Accord- ing to WHO, more than 1.2 million women were diagnosed with breast cancer in 2008. The chance of developing invasive breast cancer during a woman’s lifetime is approximately 1 in 7 (13.4%). Though much less common, breast cancer also occurs in men. The high incidence and mortality rates of breast cancer, as well as the high cost of treatment and limited resources available, require that it should continue to be a focus of attention for public health authorities and policy-makers. The costs and benefits of fighting breast cancer, including the positive impact that early detection and screening can have, need to be carefully weighed against other competing health needs. Early detection with extensive screening and modern therapy has great potential to reduce mortality from breast cancer. The existing literature on breast imaging technologies is clouded with uncertainty. There is hardly any perfect method to tell which technique per- forms better or the best. However, mammography is considered in many developed countries as the gold standard for early detection. A mammogram can detect cancer as much as a year or two before person or physician can feel it. Breast cancer detected in its earliest stages offers the greatest chance of remission and survival. It could reduce the mortality of breast cancer by 45% in women above the age of 50 years who have been screened. Screening programmes should be undertaken only when their effectiveness has been demonstrated with sound evidence. Such pro- grammes require sufficient resources to cover nearly the entire target group, means for confirming diagnoses, facilities for treatment and follow-up of those with abnormal results, and justification of the effort and costs of screening when prevalence of the disease is high enough. While screening mammography can detect most breast cancers, it can miss up to 15% of cancers. If a physician detects a breast lump with physical examination but the mammography does not reveal any abnormality, he or she will most likely recommend additional breast imaging to further investigate the lump. Guidelines for the management of breast cancer prepared by the World health Organi- zation Regional Office for the Eastern Mediterranean and King Faisal Specialist Hospital and Research Centre (a WHO collaborat- ing centre for cancer prevention and care) provide an outline of the elements involved in diagnosis including clinical examination, laboratory investigation, pathologic diagnosis, staging and risk assessment, and prognostic factors1. 1Guidelines for management of breast cancer.

Miller 1 1Associate Director Research, Dalla Lana School of Public Health, University of Toronto, Toronto, Canada (Correspondence to A.B. Miller: ab.miller@sympatico.ca). Breast cancer is the most important cancer in women in the World Health Organization (WHO) Eastern Medi- terranean Region (EMR), being the number one cancer in 16 of the 22 countries. In many technically advanced countries mammography screening, generally from the age of 50 years, is the most common breast cancer control strategy performed. The WHO has rec- ommended a step-wise approach to in- troducing screening, beginning with the promotion of early diagnosis through public and professional education, to pilot studies of organized programmes, followed by national programmes as resources permit [1,2]. This approach has been incorporated in the Cancer Control Strategy of the EMR Office of WHO. In summary, the planning steps include: 1: Where are we now? Assess the cancer problem;• Assess the evidence-base for screen-• ing; Consider alternative strategies to • reach the same objectives (primary prevention or improved treatment); Assess the existing early detection • plan and ongoing activities 2: Where do we want to be? Define the target population for early • detection of frequent cancers; Identify gaps in early detection serv-• ices; Set objectives for early diagnosis and • screening; Assess the feasibility of screening in-• terventions; Set priorities for screening.• 3: How do we get there? Plan procurement of key res ources;• Determine activities for early diagno-• sis and screening; Work with multidisciplinary and mul-• tisectoral teams; Move from policy to implemen-• tation. Working through these steps in rela- tion to each priority cancer site provides the basis for the organization of screen- ing and enables strategic decisions to be made to start or stop screening for a specific site as part of a country’s Na- tional Cancer Control Plan. In this issue of the EMHJ, Akhtar et al. describe the initial results from the pilot phase of a mammography screen- ing programme in Saudi Arabia. The authors are to be complimented on conducting this pilot phase in a defined area. A great deal of care seems to have been taken to try and ensure the project was a success. However, compliance with attendance for mammography screening was low, and the rate of recall for abnormalities suspected high, while the numbers of breast cancers detected were small. The authors admit that by the standards of many organizations in the more developed countries, various indicators suggest a need for much more attention to some of the components of an organized screening programme. In the study of Akhtar et al., 4 wom- en were detected with invasive breast cancer as a result of the screening of 1628 women, a detection rate of 2.5 per 1000. This breast cancer detection rate was low, largely because the majority of those screened were young. The age of 1 woman detected with breast cancer was unknown, but of the 3 with known ages, all were between 41 and 50 years. The 1 case of ductal carcinoma in situ (DCIS) was detected in a younger woman. However, there is no good evidence that detecting cases of DCIS is benefi- cial as these lesions, though markers of risk, are not precursors of breast cancer in the classic sense. The numbers of detected invasive cancers, though small, are compatible with the expected incidence of breast cancer in Saudi Arabia in women aged 40–49 years. They are lower, however, than was found in a population-based breast screening trial in Cairo, Egypt, which used clinical breast examinations performed by specially trained female doctors in sessions at primary health centres as the primary screen, mam- mography being used for diagnosis in a hospital serving the community [3]. Possible explanations for the higher detection rate in Cairo are that the social workers, who visited women in their homes to invite them for screen- ing, were more successful in persuading women with potential breast problems to attend, and breast cancer incidence is higher in Egypt than in many other countries in the EMR, including Saudi Arabia. Thus the Cairo trial has shown طسوتلما قشرل ةيحصلا ةلجلماشرع سداسلا دلجلما شراعلا ددعلا 1023 that it is feasible to use social workers to invite women to attend for screen- ing breast examinations while there is preliminary indication that a stage shift has been achieved [4]. In Morocco, after a pilot study of mammography screening, it has been decided to base breast screening nationally on clinical breast examinations. A similar decision has been taken in Oman. In Egypt, the Ministry of Health and Population has initiated a mammography screening programme, using digital mammogra- phy, with images read in a central loca- tion. Although based on mobile units visiting primary health care centres, this seems to be largely opportunistic. Data on coverage of the target group have not been published. Successful screening requires a fully organized programme. An organized screening programme has a number of components, including: An identifiable target group or popu-• lation, with accompanying popula- tion registers; Implementation measures available • to guarantee high coverage and par- ticipation; Access to high-quality screening;• Effective referral system in place for • diagnosis and treatment; Measures in place to monitor and • evaluate a programme [5]. The alternative to organized screen- ing is opportunistic, or laissez faire, screening. Organized screening is distin- guished from opportunistic screening primarily on the basis of how invitations to screening are extended. In organized screening, invitations should be issued to those at risk in a defined target popu- lation, preferably through population registers, and measures instituted to facilitate their attendance for screening. In this context, risk is usually defined by age and sex. In opportunistic screening, invitations to screening are extended to individuals when they encounter health care providers for reasons unrelated to cancer. Opportunistic screening is often inefficient because many who are screened are not at high risk of cancer; many in the population who should be screened are not, and those that do re- ceive screening may be screened either too frequently or too infrequently. All screening programmes require some degree of organization to be successful, and as the extent of the organization of the various elements of screening increases, so too does the impact of the programme. In the project described by Akhtar et al. the invitations issued were disseminated by public informa- tion campaigns, and were not based upon a defined register. It would seem that in this region of Saudi Arabia, this approach was not sufficient to ensure that the majority of women in the target group attended for screening. This sug- gests that further pilot phases are needed evaluating ways to recruit women into screening before a national programme can be mounted. One option would be to evaluate the use of social workers, as is being done in Sana’a, Yemen, and Khartoum, Sudan, on the lines of the Cairo trial [4]. Another aspect of the study of Akhtar et al. to be reconsidered is the age group of women included. In west- ern Europe and North America, the large majority of programmes do not in- clude women under the age of 50 years. Although this has not been the case in the United States of America (USA), where the American Cancer Society and the American College of Radiology urge annual screening from the age of 40 years, recently the US Preventive Services Task Force recommended that women aged 40–49 years should not receive routine mammography screen- ing [6]. The reasons for this were that the expected benefit was small, and the harm (in the form of excessive investi- gations) high. The number needed to invite for screening to prevent 1 breast cancer death was calculated as 1904 [7]. I have calculated that in nearly every country in the Region, it would be necessary to screen over 2000 women aged 35–39 years to detect 1 case of breast cancer, approximately double the number that would need to be invited if they were aged 40–49 years, which implies that it would be necessary to invite approximately 5000 women aged 35–39 years to prevent 1 death from breast cancer under the assumption that there is a benefit from screening in this age group, for which there is, as yet, no evidence. Thus, it would be more efficient in the future not to attempt to recruit women under the age of 40 years. Indeed including women from the age of 35 years in routine mammog- raphy screening programmes has never been advocated in the more developed countries, even in the USA. Because of the larger number of younger than older women in most countries in the EMR, clinically a higher proportion of women in their thirties and forties present with breast can- cer than would be the expectation in western Europe and North America. This has led to the misunderstanding that somehow breast cancer is differ- ent in the countries in the Region than in more developed countries. How- ever, when population-based cancer registries are active and it is possible to compute the risk of the development of breast cancer by age, it appears that the incidence of breast cancer at each age is no higher, though it is often much lower at older ages. This creates a problem for countries in the Region considering mammography screening, as it is now accepted that mammography screening is less effective in women under the age of 50 years than in older women [7,8]. The difficulty in recruiting women into screening, and its likely low efficacy in relation to the main burden of breast cancer in younger women, suggests that there is a substantial risk of very little benefit from breast screening in the Region, and that the priority should shift to early diagnosis through health education, combined with effective treatment of detected cases.

References Early diagnosis is defined by WHO as the awareness (by the public or health professionals) of early signs and symptoms of cancer in order to facilitate diagnosis before the disease becomes advanced [2]. This enables more effective and simpler therapy. The concept of early diagnosis is sometimes called “down-staging”. In a population where the majority of the cancers ame- nable to early detection are diagnosed in late stages, the establishment of an early diagnosis programme may be the most feasible strategy to reduce the percentage of advanced stages and im- prove survival rates [2]. To introduce an early diagnosis programme based on health education, however, will re- quire special studies to help understand women’s’ concept of the importance of breast cancer and its curability if de- tected early, and the ways to change often basic misunderstandings. Any education programme devised must be culturally appropriate, so it cannot simply be imported from the types of programmes and pamphlets developed in other regions. Further, it may be necessary to ensure such education is also addressed to men as they may be influential in the decision-making that results in a woman attending a primary health care centre for diagnosis if she becomes concerned about her breasts. It will also mean that primary care physicians may have to undergo re-training, partly to ensure they do not have the same misunderstanding of the potential curability of breast cancer as their patients, but also so that they are able to recognize the signs of early breast cancer. Once an early diagnosis programme is in place and there is evidence that it is being successful, then, in accord- ance with WHO guidelines, it would be appropriate to consider screening. However, if resources are not sufficient to consider nationwide mammography screening, it might be preferable to start by introducing pilot programmes of Clinical Breast Examination screen- ing, along the lines of the Cairo trial, or following the model of Morocco and Oman, reserving mammography for diagnosis. It is relevant that in the Canadian National Breast Screening Study we found no benefit from adding annual mammography to clinical breast examination screening in women aged 50–59 years [9]. طسوتلما قشرل ةيحصلا ةلجلماشرع سداسلا دلجلما شراعلا ددعلا 1025 First organized screening mammography programme in Saudi Arabia: preliminary analysis of pilot round S.S.

Analysis was conducted in the central screening office in Prince Faisal Oncology Centre, which coordinates activities of various screening units. Data were collected during the period 1 January 2007 to 30 June 2008. Organizational and functional information was obtained from policy and procedure manuals of the programme. Out of 9812 eligible women, 1766 (18%) participated and data were available for 1628 (16.6%). The median age of participants was 47 (standard deviation 8.12) years. The low uptake rate (18%) and a high recall rate (31.6%) characterized the pilot screening round. Biopsy rate was 1.5% and cancer detection rate was 0.24%. Many performance indicators in this pilot screening round were not available. Many of the available indicators did not meet international standards. 1Al-Qassim Screening Mammography Programme; 5Department of Family Medicine and Awareness Programme Committee, Al-Qassim Screening Mammography Programme, Buraidah, Al-Qassim, Saudi Arabia (Correspondence to S.S.

L’analyse a été effectuée dans le bureau central de dépistage de Prince Faisal Oncology Centre, qui coordonne les activités de diverses unités de dépistage. Les données ont été collectées entre le 1er janvier 2007 et le 30 juin 2008. Les informations organisationnelles et fonctionnelles ont été extraites des manuels de politique et de procédures du programme. Sur 9812 femmes correspondant aux critères, 1766 d’entre elles (soit 18 %) ont participé à l’étude ; des données ont pu être collectées pour 1628 femmes (soit 16,6 %). L’âge médian des participantes était de 47 ans (écart-type 8,12). L’opération pilote de dépistage s’est caractérisée par un faible taux de participation (18 %) et un taux de rappel élevé (31,6 %). Le taux de biopsie était de 1,5 % et le taux de dépistage du cancer de 0,24 %. Il manquait de nombreux indicateurs de performance dans cette opération. Enfin, un grand nombre des indicateurs disponibles ne satisfaisaient pas les normes internationales. EMHJ • Vol. 16 No.10 • 2010 Eastern Mediterranean Health Journal La Revue de Santé de la Méditerranée orientale 1026 Introduction Large randomized controlled trials and meta-analyses have reported a significant decrease in breast cancer mortality in women through screening mammography [1,2]. As a result, many countries in Europe and North Amer- ica have initiated national or regional screening mammography programmes for breast cancer [3]. The majority of the developing countries barely have resources to meet the basic needs of their population. The baseline incidence of breast cancer in these countries may still be too low to justify wide applica- tion of such population-based screen- ing programmes. However, there is a documented increase in breast cancer incidence in most of these countries, and this is expected to rise further [4]. Since such programmes may take as long as a decade to become operational- ly effective, it is prudent that if resources exist, plans to decrease mortality due to breast cancer should be activated before it is too late. According to the 2008 report of the World Health Organization, life expectancy of Saudi Arabian females is 73 years [5]. Saudi Arabia, an afflu- ent country, spends 3.4% of its gross domestic product on health care. This is the equivalent of around US$ 607 spent per capita annually [5]. Breast cancer is the commonest cancer seen in females in Saudi Arabia, and the majority of patients present with advanced stage of disease [6,7]. As resources are avail- able, initiation of a population-based screening mammography programme is feasible. As has been shown in the industrial- ized countries as well as in neighbouring countries, implementation and par- ticipation in screening mammography programmes may reduce the incidence of late stage of breast cancer at pres- entation, which may be an added ad- vantage of such a programme in Saudi Arabia [7–9]. It is indeed recognized that the social and traditional values of the population may influence accept- ance of such a programme. It is impor- tant to recognize that participation in breast cancer screening programmes is influenced by a multitude of local fac- tors. Studies conducted in the Islamic Republic of Iran, Lebanon and Qatar have shown that participation in screen- ing programmes may be affected by religious belief, fear of encounter with a male physician, embarrassment and fear of the test itself [10–12]. Recently, the pilot round of the population-based screening mam- mography programme conceived in the central Al-Qassim region of Saudi Arabia was concluded. This programme is expected to be the basis for a future national programme. We present here the preliminary analysis of the pilot round of this programme. Methods Approval for conducting this analysis was acquired from the regional ethics committee. The organizational structure of the programme is shown in Figure 1. Unaizah is a mainly urban area of Al- Qassim region. It has a well-established network of primary health care centres (PHCs) connected by well-developed roads, telephones and the Internet to a secondary care hospital in the area, King Saud Hospital. Owing to its cen- tral location and proximity to Buraidah, the capital city of Al-Qassim region, Un- aizah was selected for the pilot screening round. Another rural township, Okalat- al Sakur, which has many desert dwell- ers living in the surrounding desert area of the region, was also included in the pilot project. A public awareness team was consti- tuted by community medicine experts and consisted of female Saudi Arabian nurses, female social workers and a committed group of female volunteers from the public. They held interactive sessions with females invited from the pilot areas to discuss the importance of screening mammography and the methods used. The public awareness campaign also included exhibitions, lectures, information stalls in shopping malls, and boards and banners displayed in the prominent areas of the region. The male members of the team held special sessions for the male residents of the pi- lot areas, and details of the programme were discussed. Community leaders, government officials, teachers, clergy and other persons of social importance were specially invited. The awareness campaign preceded the launch of ac- tual screening by 6 months. The role of the media in this campaign was limited to the coverage of various events. The programme started recruiting from 1 January 2007 and the first round was completed on 30 June 2008. Al-Qassim Screening Mammog- raphy Programme is aimed at women aged 35–60 years. The screening inter- val is 18 months. To be eligible, women should not be lactating or pregnant, and should have no breast symptoms. Exclusion criteria also included previ- ous breast cancer, breast implants and a mammogram within the previous 18 months. Digital mammography has the advantage of film-less digital storage, archiving at a distant site, easy retrieval and manipulation of images. Since there are data demonstrating the superiority of digital mammography over film mam- mography in younger women, it was decided to use only digital mammog- raphy units for this programme [13]. A team of radiologists and radiation physicists assessed the available mam- mography equipment in the region: 7 analogue units were available. After as- sessment the units were either upgraded to Computed Radiography System for mammography (CR) or replaced by Digital Mammography System (DR) units. Initially 2 DR units were procured for the pilot project screening sites: a mobile unit (Selenia Full Field Digital Mammography System, Hologic) and طسوتلما قشرل ةيحصلا ةلجلماشرع سداسلا دلجلما شراعلا ددعلا 1027 another unit (Siemens, Mammomat Novation) was installed in King Saud Hospital, Unaizah. A DR unit (GE Senographe 2000D) and another CR unit (Agfa, Belgium) were located at King Fahd Specialist Hospital, a tertiary care referral hospital, in Buraidah. This hospital has the only oncology centre (Prince Faisal Oncology Centre) in the region, where a regular breast health clinic is run. Two ultrasound machines with high-resolution probes and elas- tography facility (Hitachi, Japan and GE, United States of America) were installed for the pilot project, 1 at each hospital. Whenever required, the par- ticipants were referred to King Fahd Specialist Hospital for stereotactic bi- opsy procedures. The screening units consisted of 2 radiologists and a team of radiographers and mammographers. Additional mam- mographers were selected from a pool of female Saudi technologists/nurses. A team of dedicated mammographers trained them for a period of 3 months prior to the start of programme. A female coordinator was designated as liaison between the participating teams at the static and mobile units. The mobile unit was stationed at the 30-bed hospital in Okalat-al Sakur region to cater to that area. The DICOM (Digital Imaging and Communication in Medicine) im- ages were digitally archived and read at the central reporting office at King Fahd Specialist Hospital. Data were stored in a locally developed database programme. The mammography screening com- prised 2 views, craniocaudal and medi- olateral oblique. Two radiologists read the images independently, and only in the event of consensus was the decision taken either to investigate the patient further or return her to a routine follow- up. In case of discordance between the 2 radiologists, a third reading by a senior member of the central team was taken as decisive. In Al-Qassim region medical records of almost all the inhabitants are maintained at the local PHC. From these files, the PHC department pre- pared a list of registered females in the areas selected for the pilot round. For each PHC, women of eligible age group were short-listed with their contact numbers and address. In each PHC, a coordinator was designated to com- municate with eligible females and the screening unit. Every eligible woman was contacted and, after checking exclu- sion criteria, invited to the PHC where demographic data were recorded on a previously drafted form.

The coordinator secured appointments for screening as well as subsequent assessment of the clients ac- cording to their convenience and men- strual cycle. The assessment protocol at the PHC and a flow diagram of the programme are shown in Figures 2 and 3 respectively. Commencement of the programme was announced through various media channels, newspapers and display posters in the region. The screening results were communicated through the PHC and for those recalled an appointment was made in the assess- ment clinics at King Saud Hospital or King Fahd Specialist Hospital. Details of participants undergoing any kind of biopsy procedure were dis- cussed in the multidisciplinary team meetings. Those needing therapy were referred to Prince Faisal Oncology Cen- tre (Figure 3). Results According to the 2004 census, the to- tal number of Saudi Arabian women in Al-Qassim region was 409 970, of whom 74 476 were aged 35–60 years [14]. Out of these, 9812 resided in the 2 health care sectors selected for the pilot screening round and these constituted the target group. Only 1766 responded to the call and attended the screening round, resulting in an uptake rate of 17.99% for the first 18-month cycle of the programme. Data were available for 1628 clients in the temporary database developed for the purpose. The median age of the participants was 47 (standard deviation 8.12) years and the mean was 46.8 years. Age distribution of the participants is shown in Table 1: 54 of the participat- ing women were over 60 years and 6 were over 70 years. Following the initial screening round, 925 (56.82%) women were sent back to return for a routine round after 18 months, while as 515 (31.6%) were recalled for an early reassessment. For 188 women (11.5%) there was no infor- mation about follow-up in the database. The detailed performance and quality indicators of the pilot round are shown in Table 2. Tables 1 and 3 show the biopsy, cancer detection rate and follow-up as related to the age groups screened. Our early recall rate ranged from 28.2% in 51-55 age group to a very high of 41.2% in women >70 years of age (Table 1). As shown in Table 3, no invasive cancer was detected in women younger than 40 years of age in this pilot round. Discussion In a previous study from Al-Qassim, around 50% of women residing in the region had never heard about breast self examination, and those who had did not practise it regularly [15]. Improving awareness and practice rates of breast self examination among the popula- tion could be an easy and cost–effective method for early detection of breast can- cer in a country with different cultural, ethnic and racial make-up. However, a recent trial involving 300 000 women in another developing country, China, in- dicated that breast self examination did not reduce breast cancer mortality rates [16]. Screening mammography there- fore, remains the method of choice to decrease mortality due to breast cancer. Organized screening programmes can ensure quality control of the screening process and monitor interim indica- tors showing whether the programme is on track towards achieving a reduc- tion in breast cancer mortality in the population. Conversely, opportunistic programmes such as charity or fee for service programmes are delivered in an ad hoc fashion without targeting or recalling women who are most likely to Figure 3 Al-Qassim Screening Mammography Programme: flow chart of screening process (PHC = primary health care centre; PFOC = Prince Faisal Oncology Centre) Cancer Normal/benign Screening visit Programme participants Non-participants Normal Abnormal Asymptomatic ≥ 35 – < 60 years Communicate result to woman through the physician Personal invitation to re-screen PFOC for therapy Diagnostic follow-up at PFOC Breast Health Clinic Communicate result and appointment to woman through PHC physician Programme promotion: Awareness campaign Physician education Personal invitation to screening through PHC طسوتلما قشرل ةيحصلا ةلجلماشرع سداسلا دلجلما شراعلا ددعلا 1029 benefit from screening mammography. A recent study comparing the 2 types of screening has confirmed the higher sensitivity of a population-based pro- gramme [17] Al-Qassim Screening Mammog- raphy Programme is the first organ- ized population-based screening mammography programme in Saudi Arabia. It was imperative that results were compared to international standards to confirm that the programme was achieving its goals. The uptake of our pilot screen- ing round (17.9%) was much lower than reported in similar pilot projects conducted in Europe: 42%–45% in a Swiss pilot project, 36.7% in a French pilot programme, 36% in Luxembourg and 45.1% in a first round in Hungary [18–21]. Our uptake rate was much lower than the standard figure of more than 70% recommended by the Euro- pean Union and the United Kingdom [22,23]. The factors known to influence first time attendance for screening include being married, working, low or mid- dle levels of education and income, misinformation, ineffective health communication, competing priorities, participating in early detection prac- tices, perceiving mammography as a sensitive technique for detecting breast cancer and seeing oneself as suscep- tible to breast cancer [24,25]. Indeed the characteristics and demography of our population were quite unlike the Europeans, with strong cultural differ- ences. These could have had a bearing on uptake rate in our programme. In future, it would be interesting to analyse the factors and barriers affecting the participation by the eligible population of this region. The recall rate, 31.6%, for early as- sessment in the pilot screening round was much higher than the international guidelines set by the European Union and the United Kingdom (Table 2). Ac- cording to European Union guidelines, the proportion of women recalled for early assessment should be less than 7% in an initial screening examination, and the desirable level is below 5% [22]. In a review of European programmes, the recall rate varied from 1.3%–18.4% Table 1 Al-Qassim screening mammography programme pilot screening round: type of recall related to the age group of screened population Age group (years) No. women screened Type of recall Routine Early No information No. % No. % No. % ≤ 40 353 221 62.6 104 29.5 28 7.9 41–45 346 199 57.5 111 32.1 36 10.4 46–50 401 212 52.9 139 34.7 50 12.5 51–55 294 176 59.9 83 28.2 35 11.9 56–60 158 80 50.6 55 34.8 23 14.6 61–65 37 19 51.4 12 32.4 6 16.2 > 65 17 8 47.1 7 41.2 2 11.8 Unknown 22 10 45.5 4 18.2 8 36.4 Total 1628 925 56.8 515 31.6 188 11.5 Table 2 Performance and quality indicators of the pilot screening round of the Al- Qassim Screening Mammography Programme Indicator Present series International standard EU [14] UK [15] No. of women eligible for pilot project in the 2 health sectors (target population) 9812 No. of women screened 1766 Uptake rate (%) 17.9 > 75 > 75 No. of women for whom data were available 1628 No. of women recalled 515 Recall ratea (%) 31.6 < 5 < 7 Total No. of biopsiesb 25 Biopsy rate (%) 1.5 Biopsy rate among recalled patientsa (%) 4.85 Benign biopsy rate per 1000 screened 12.3 < 3.6 Total no. of cancers detected 5 No. of invasive cancers 4 Cancer detection rate per 1000 screened 2.45 > 1.5 DCIS per 1000 screened 0.61 > 0.4 – < 0.9 DCIS (% of malignant cases) 20 > 15 aTotal number biopsies/number of women recalled for assessment ×100. bIncludes stereotactic core biopsies, fine needle aspiration cytology and open surgical biopsies.

In another comparative assess- ment of performance indicators of in- ternational screening mammography programmes in 14 countries, recall rate on initial screening varied from 1.4% in the Netherlands to 15.1% in the United States of America [27]. A decline in recall rate across age and in subsequent screens has also been documented [27]. We did not note a decline in the recall rate with increasing age: in our pilot round, recall rate was lowest in the age group 51–55 years (28.2%) and highest in women aged over 65 years (41.2%). A high recall rate causes psychologi- cal morbidity and indicates inefficient use of screening resources and women have to undergo unnecessary and costly follow-up investigations. At the same time, too low a recall rate may decrease the detection rate and increase the in- cidence of subsequent interval cancers. Double reading by consensus or arbitra- tion reportedly decreases the recall rate [28]. This is standard practice in our pro- gramme, hence should have decreased the recall rate. Numerous explanations could be hypothesized to explain our high recall rate: our physicians may tend to recall women with suspicious find- ings, even in the absence of a possibility of cancer, to avoid possible malpractice litigation; our mammography readers are low-volume readers by definition, interpreting around 100 mammograms a month; interpreting a high volume of mammograms is known to lessen the recall rate [29]. Other factors, which are known to have an impact on the recall rate include the age of the screened population, type of mammography equipment used, technical problems and training of the mammography staff. It would be inter- esting to analyse the reasons for the high recall rate in a future study. In French pilot and Norwegian pro- grammes the biopsy rate was similar to our rate: 1.2% and 1.9% respectively [19,30]. The biopsy rate may be related to the rate of recall. A higher recall rate will decrease the proportion of women biopsied among those recalled com- pared to a programme with a low recall rate. The number of biopsies related to the total number screened, of course, re- mains constant. The biopsy rate among our recalled women was 4.85%, which is quite low compared to 39.2% in the Norwegian programme [30]. The cancer detection rate in this first screen, also called prevalent screen, was 0.24%. Cancer detection rate de- pends upon baseline incidence of breast cancer in the population. Consequently, the detection rate in our programme was lower than even those European countries that have the lowest detec- tion rates, Finland 0.37% and Hungary 0.36% [21,31]. Conclusion Many performance indicators of the pilot round of Al-Qassim Screening Mammography Programme were not available. Many of those available did not meet recommended international standards. There is an urgent need to review and revise the whole programme in order to achieve the following goals: increase the participation rate,• decrease the recall rate,• improve the detection rate,• develop or procure a purpose-built • database with trained staff to receive, enter and analyse the data.

Arkoob,1 M. Al-Nsour,2 O. Al-Nemry 3 and B. Al-Hajawi 2 ABSTRACT The 5-year survival rate of female breast cancer cases in Jordan and some of the factors that affected survival were measured. All Jordanian women newly diagnosed with breast cancer during 1997–98 were included. Data were obtained retrospectively from the Jordan Cancer Registry and hospital records. Of 838 women included, half were diagnosed between the ages 40 and 59 years. The overall Kaplan–Meier 5-year survival rate was 59.3%. Stage, laterality and grade had a significant effect on survival rate. However, Cox proportional regression showed that tumour stage was the only factor that significantly influenced survival analysis after controlling for other factors. Further studies are needed to confirm the results and to ensure the inclusion of other factors. 1Al-Basheer Hospital, Ministry of Health, Jordan. 2Disease Control and Prevention Directorate, Ministry of Health, Jordan (Correspondence to M.

Toutes les femmes jordaniennes chez lesquelles un nouveau diagnostic de cancer du sein avait été posé en 1997-1998 ont été incluses. Les données ont été obtenues rétrospectivement dans le Registre du cancer jordanien et les dossiers hospitaliers. Pour la moitié des 838 femmes incluses, le diagnostic avait été établi entre 40 et 59 ans. Le taux de survie global à cinq ans par la méthode Kaplan-Meier était de 59,3 %. Le stade, la latéralité et le grade avaient un effet important sur le taux de survie. Toutefois, le modèle de régression à effet proportionnel de Cox a révélé que le stade de la tumeur était l’unique facteur ayant une véritable influence sur l’analyse de la survie après l’élimination d’autres facteurs. Des études supplémentaires sont nécessaires pour confirmer les résultats et garantir l’inclusion d’autres facteurs. طسوتلما قشرل ةيحصلا ةلجلماشرع سداسلا دلجلما شراعلا ددعلا 1033 Introduction Breast cancer is considered to be the most common cancer throughout the world. Statistics show that about 700 000 cases are reported annually, about 57% of them in developing coun- tries [1]. Data from the United States of America indicate that the incidence of breast cancer increases directly with age until 75–80 years [2]. In Jordan, cancer is the second most frequent cause of death after cardiovascular disease [3]. According to official Jordanian statistics, breast cancer was the most common of all cancers in women in the last decade [3], a figure that agrees with the results obtained from different countries in the region [4,5]. The survival rate is one of the most important measures of cancer care, and is a valuable tool for comparisons between countries. Studies of cancer patient sur- vival, using data from population-based cancer registries, are essential for moni- toring and evaluating the effectiveness of the diagnosis and treatment of cancer [6]. The higher survival rates being re- corded in some developed countries reflect improvements that have taken place in various areas of cancer control, from health education and early diag- nosis to treatment and after care [7]. In- formation about survival rates in Jordan will help us take further preventive and control measures in order to improve the prognosis of patients with different types of cancers. The present study aim to identify the epidemiology of female breast cancer in Jordan in 1997–98; to measure the observed 5-year survival of female breast cancer cases diagnosed in Jordan in the years 1997–98; and to explore some of the factors that affect survival rates, such as age at diagnosis, type, grade and stage of tumour. The majority of studies in Jordan to date have been descriptive, and to the best of our knowledge this is the first study of survival rates at population-based registry level in Jordan. Methods Study design This was a descriptive study using data from the Jordan Cancer Registry (JCR). Established in 1996, the JCR is a population-based registry that provides statistics on the incidence of cancer throughout Jordan. JCR obtains its information about patients from governmental and nongovernmental health care facilities and military hospi- tals throughout the country and from laboratories and the Jordan National Civil Department. Liaison personnel in the main hospitals are responsible for registering and reporting all cases of cancer by completing a special form containing demographic and medical data, which is sent to JCR. Data collection for the current study lasted more than 3 months. All cases of breast cancer in women that were registered in the JCR and were newly diagnosed during the period 1 Janu- ary 1997 to 31 December 1998 were included in the study. Cases that could not be verified by a histopathology re- port were excluded. Data collection Special data collection forms were designed for the study to collect so- ciodemographic information about the patient (national ID number, name, age at diagnosis, address) and information related to current cancer status (his- topathology report, laterality, stage of cancer, grade and stage of the tumour, date of diagnosis, date of last visit, and outcome). The validity and reliability of the study instrument were tested in a pilot study and some variables in the data collection instrument were modified. Patients were first identified from the JCR registry, after which the medi- cal records and histopathology reports from the reporting hospital were con- sulted to complete the data. The out- come (alive or dead) was ascertained from the Civil Registration Department using the patient’s unique national ID number. Each patient was followed up until dead or alive at the end of data col- lection period, i.e. for up to 5 years from the date of diagnosis to the cutoff point at 31 December 2003. The follow-up endpoint was death from any cause. Some patients were lost to follow-up as no information was available about them. The final number of patients was 838. Duplication of data was avoided by using the patient’s unique national ID number and full (4) names (patient, father, grandfather and family name). Official approval for the study was obtained from the medical ethics com- mittee of the Ministry of Health before starting data collection. All informa- tion about patients was handled under conditions of strict confidentiality and data were analysed anonymously by ID number. No contact was made with patients or their relatives. Definitions Laterality was subdivided into right, left, bilateral and unknown (undetermined or data missing). Histopathology type was categorized into: ductal carcinoma, lobular carcinoma, adenocarcinoma, medullary carcinoma and unknown (undetermined type or data missing). Tumour stage was classified into 4 stages using the American Joint Com- mittee on Cancer TNM [tumour, node, metastasis] criteria: stage I, stage II, stage III, stage VI or unknown (undetermined stage or data missing). Tumour grade was divided into 5 cat- egories: grade 1 (well-differentiated); grade 2 (moderately differentiated); grade 3 (poorly differentiated); grade 4 (undifferentiated) and unknown (undetermined grade or data missing). Data management and statistical analysis Data were entered and analysed using SPSS, version 12. Frequencies of so- ciodemographic and clinical character- istics of all patients were obtained. The survival rates at 1-year intervals were EMHJ • Vol. 16 No.10 • 2010 Eastern Mediterranean Health Journal La Revue de Santé de la Méditerranée orientale 1034 estimated using the actuarial (life-table) method and overall survival rates us- ing exact survival times were estimated using the Kaplan–Meier product limit technique. Log-rank testing was used to test for an association between the variables and the survival rate. P-value < 0.05 was considered statistically sig- nificant. Survival probabilities by age, type of cancer, laterality, grade, stage and treatment were obtained. Cox pro- portional hazard regression analysis was performed to assess the independent effect of different prognostic factors after simultaneously controlling for the effect of potential confounders. Initially all of the following variables were entered in the model: age, type, laterality, grade, stage and treatment modality. Results A total of 838 women with breast cancer were included in this study. The mean age of the patients was 50.2 (standard deviation 12.4) years. Slightly more than half the patients diagnosed fell into the 40–49 and 50–59 years age groups. The left breast was the most commonly affected site (44.6%). More than three-quarters (77.5%) of patients were diagnosed with ductal carcinoma and 41.7% of tumours were moder- ately well-differentiated. Almost half (47%) the patients received combined treatment of surgery, chemotherapy and radiotherapy. More than one-third of patients (37.6%) were in stage II at diagnosis. The period of follow-up ranged from 1 day to 5 years. Just over half the patients (51.4%) were known to be still alive 5 years after first diagnosis, while 34.8% were recorded as dead and data were missing for 13.9% (Table 1). Calculation of the survival rates at 1-year intervals are presented in Tables 2 and 3. Using the actuarial method, the 5-year survival rate for breast cancer cases was 59.3% (Table 2). The percentage of women surviving 1 year after diagnosis was 91.6%, for 2 years 80.1%, for 3 years 70.2% and for 4 years 65.8%. The cumulative 5-year survival rates by the Kaplan–Meier method as a func- tion of the different prognostic factors studied (age, type, laterality, grade, stage and treatment) are presented in Table 3. Figure 1 shows the survival curves for the same variables. The high- est 5-year survival rate by age was in the age group 40–49 years (67.2%), and the poorest survival rate in the age group > 30 years (43.8%).

EMHJ • Vol. 16 No.10 • 2010 Eastern Mediterranean Health Journal La Revue de Santé de la Méditerranée orientale 1036 Figure 1 Breast cancer survival rates in women diagnosed in Jordan 1997–98 according to selected variables (RT = radiotherapy; CTR = chemotherapy) طسوتلما قشرل ةيحصلا ةلجلماشرع سداسلا دلجلما شراعلا ددعلا 1037 was 61.1% and for the left breast was 59.1%; however the survival rate was only 16.7% for bilateral breast cancer, a difference that was statistically signifi- cant (P < 0.001). According to the dif- ferentiation grade of the tumour, 5-year survival for well-differentiated tumours was 73.9% compared with 42.9% for undifferentiated tumours (P < 0.001). The 5-year survival rates were 71.4%, 39.6% and 5.8% for tumours in stage II, III and IV at diagnosis respectively (P < 0.001). Regarding treatment given to the patients, 5-year survival for pa- tients receiving only surgery was slightly higher (58.3%) than for those receiving triple therapy of surgery, chemotherapy and radiotherapy (56.3%), but the dif- ference was not significant (P = 0.45). Cox proportional hazard regression analysis was performed to assess the in- dependent effect of different prognostic factors after simultaneously controlling for the effect of potential confound- ers. All of the following variables were initially entered into the model—age, type, laterality, grade, stage and treat- ment modality—but only laterality, grade and stage of cancer were kept in the final model. Table 4 shows the haz- ard ratio and the significance for these 3 variables. According to tumour stage the best survival was found for stage I (hazard ratio of dying = 1.00) compared with the other stages (P < 0.001). The grade of the tumour and the laterality did not reach the level of significance in the model. Discussion Our study provides substantial informa- tion about the survival rate of women diagnosed with breast cancer in Jordan in 1997–98. While TNM staging at diagnosis, laterality and grade had a significant effect on survival rate, Cox proportional regression analysis showed that after controlling for other factors tumour stage was the only factor that influenced survival. Age and grade had no statistically significant association with survival. Consistent with studies from other countries in the region [8–11], our study showed that the overall 5-year survival rate for breast cancer in Jordan, regardless of stage or grade, was 59.6%. The 1-year rate was 91.6%, the 2-year rate was 80.1%, the 3-year rate was 70.2% and the 4-year rate was 65.8%. In line with other studies, we found that the overall survival rate was poorer in the age group < 30 years (43.8%) compared with the age group > 70 years (56.5%) [12–14]. Lack of competing causes of death, higher frequency of un- differentiated tumours and more cases diagnosed at stage II or III have previ- ously been suggested as the reason for the poor survival experience of young women with breast cancer [2,15]. In contrast, a study in the United States of America about breast cancer in young patients aged < 35 years showed that overall 5- and 10-year survival rates were 65% and 49% respectively and con- cluded that young age was not directly related to the “aggressiveness” of breast cancer [16]. Consistent with a study from Europe [17], the best survival rate in our study was seen in the age group 40–49 years. This could be explained due to access to screening mammography in this age group or due to lower levels of circulating sex hormones, resulting in reduced stimulation of tumour cell growth [18,19]. There was a statistically significant association between survival and lateral- ity, which was 61.1% in the right breast and 59.1% in the left breast, while in bilateral cases the 5-year survival was only 16.7%. This is probably explained by the more aggressive disease present in bilateral cases of breast cancer. The TNM stage proved to be the most significant independent prog- nostic factor for determining survival. In our study only 55.6% of cases were diagnosed at stage I and II, whereas in Canada 75% were diagnosed at stage I and II [11]. Regular mammography combined with regular clinical examina- tion may offer the best opportunity of increasing the proportion of early stage cases detected. In our study, the 5-year survival rate varied according to stage. This was prob- ably due to the fact that stage reflects the interaction between the host and the tumour.

EMHJ • Vol. 16 No.10 • 2010 Eastern Mediterranean Health Journal La Revue de Santé de la Méditerranée orientale 1038 stage and 5-year survival by stage was similar to data reported by the Ameri- can Cancer Society [18,20]. However, information from Bahrain showed that that the 5-year survival rate ranged from 87.5% at stage I to 48% at stage IV [8], which differs from the results of the present study. A strength of our study is that it was population-based, comprising virtually all histologically verified cases registered in the JCR, and was therefore not subject to the selection bias of studies that select samples. Another important strength of the study was the ability to investigate the impact of demographic, histological and therapeutic factors on survival in breast cancer. Furthermore, the size of the study was sufficiently large to per- form survival analysis across different subgroups of breast cancer cases. On other hand, some weaknesses of our study should be addressed. First, as in other population-based studies, the medical records were not complete and there was some information missing. Although notification of cases to the JCR is mandatory, the exact cause of death was not recorded in all cases, so we assumed that cancer was the cause of death unless otherwise specified. The exact cause of death in population- based studies may not always be clearly determined. Since 30.5% of the breast cancer cases were diagnosed at stage III and stage IV, great efforts should be made to improve this percentage through a good surveillance system and screening programmes for high-risk groups. De- termining the prognosis in cancer cases depends on accurate data on prognostic factors and the appropriate choice of therapeutic and supportive interven- tions. Further studies are needed to confirm our results in a larger sample and perhaps to ensure the inclusion of other factors such as number of lymph nodes affected, pregnancy history, age at menarche, use of oral contraceptives, menopausal status and oestrogen and progesterone levels.

Jafarzadeh,1 A. Esmaeeli-Nadimi,2 M. Nemati,1 M. Tahmasbi 2 and P. Ahmadi 1 ABSTRACT To compare the serum concentrations of IgG to Helicobacter pylori and its virulence factor CagA in patients with ischaemic heart disease (IHD), we recruited 120 patients with IHD [acute myocardial infarction (AMI) (n = 60); unstable angina (UA) (n = 60)] and 60 sex- and age-matched healthy controls in this study. The seroprevalence of anti-H. pylori IgG was 86.7% in AMI, 91.7% in UA patients and 58.3% in the control group with mean titres of 33.2 U/ml [standard error (SE) 4.76], 57.96 U/ml (SE 7.54) and 25.72 U/ml (SE 4.01) respectively. The seroprevalence of anti-H. pylori in the patient groups was significantly higher than the control group. The mean levels of anti-H. pylori in the AMI and UA groups were also significantly higher than in the control group. The seroprevalence and mean titre of anti-CagA IgG did not differ significantly between patient and control groups. 1Department of Immunology, Medical School; 2Department of Internal Medicine, Ali-ebne-Abitaleb Hospital, Rafsanjan University of Medical Sciences, Rafsanjan, Islamic Republic of Iran (Correspondence to A.

EMHJ • Vol. 16 No.10 • 2010 Eastern Mediterranean Health Journal La Revue de Santé de la Méditerranée orientale 1040 Introduction A number of etiological factors have been determined for development of is- chaemic heart disease (IHD). Although there are several major known risk fac- tors for the development of coronary ar- tery disease, about 50% of patients with this condition do not have any of these risk factors [1]. It has been suggested that inflammatory reactions may play an important role in the pathogenesis of IHD [2] An association between IHD and some infectious agents including Chlamydia pneumoniae, herpes simplex virus (HSV), cytomegalovirus (CMV) and hepatitis A, respiratory tract and dental infection has been reported in some epidemiological studies [2]. How- ever, some prospective studies failed to demonstrate a strong relationship between the presence of IgG antibodies to C. pneumoniae, HSV-1 and CMV and the occurrence of coronary arte- rial disease [3]. Some investigators also have assessed the relationship between H. pylori and IHD, reporting a strong positive association [4–6] a moderate association [7–10] and even negative association [11–14]. Strains of H. pylori are genetically diverse and have been divided into type I and type II according to the expression or non-expression of cytotoxin-asso- ciated gene A (CagA) [15]. CagA has been identified as a virulence marker of H. pylori and the cagA+ strains induce more severe disease and inflammatory response [15]. Since CagA is immuno- dominant, the detection of serum IgG to the CagA antigen has been reported as a reliable marker of carriage of cagA+ H. pylori strains [16]. We have recently reported that the seroprevalence of H. pylori in healthy Iranian adults was 67.5% and in healthy children 46.6%; the prevalence of anti-CagA antibody was 72.8% in infected adults and 67.4% in infected children [17]. Elevated levels of C-reactive protein (CRP), fibrinogen, homocysteine, pro- inflammatory cytokines and antibodies to some heat shock proteins are known to be associated with an increased risk of cardiovascular events [18]. Chronic infections such as H. pylori may be behind these changes. However, the role of H. pylori as a risk factor for IHD remains debatable. This study was con- ducted for the first time to evaluate the seroprevalence of antibody to H. pylori and bacterial virulence factor CagA in Iranian patients with IHD to clarify the possible relationships. Methods A total of 120 patients aged 40–65 years with IHD who were admitted to Ali-Ebne-Abitaleb Hospital in Rafsanjan (a city in Kerman province in the south- east of the country) during the period March–December 2007 were enrolled to this cross-sectional, case-controlled study. Sample size was calculated at 50 (using P1 = 90%; P2 = 60%; α = 5%; β = 10%), which was increased to 60 in each group for the actual sample, i.e. 120 patients altogether. Patients were classified into 2 groups according to well-established criteria as having acute myocardial infarction (AMI) or unsta- ble angina (UA). AMI was diagnosed by the presence of 2 of these criteria: prolonged chest pain compatible with AMI, typical ECG changes, elevation of cardiac enzymes. Patients with non-ST elevation were excluded from the study. UA was defined according to Braun- wald’s classification and all patients had chest pain at rest with definite ischaemic electrocardiographic changes such as ST-segment changes and/or T-wave inversion; all UA patients were in class IIIB according to Braunwald’s classifica- tion [3]. Exclusion criteria were valvular heart disease, surgery, trauma within the previous month, cardiomyopathy, liver disease, renal failure, malignant diseases, other inflammatory disease (such as septicaemia and pneumonia) and oral anticoagulant therapy. A third sex- and age-matched group with similar geographic and socioeconomic status comprised 60 subjects without any IHD, registered as a control group. The healthy control group was recruited from blood donors at Rafsanjan Blood Transfusion Centre. All patients and controls were residents of Rafsanjan city. The study was evaluated and ap- proved by the Ethical Committee of Rafsanjan University of Medical Sci- ences. Informed consent was given and all those recruited had agreed to give blood samples. Peripheral blood (2–4 mL) was collected from the participants in the 3 groups and the serum separated and stored at –20 °C. In patients with AMI the serum samples were collected dur- ing 3–5 days after admission; in patients with UA they were collected at admis- sion. Determination of H. pylori- specific antibodies in serum The serum levels of anti-H. pylori im- munoglobulin G (IgG) were measured using a commercial enzyme-linked im- munosorbent assay (ELISA) (Trinity Biotec, Ireland) according to the manu- facturer’s guidelines. The results were expressed as U/mL and a cut-off value of 5 U/mL was used to discriminate negative from positive samples. Serum levels of anti-CagA IgG were also assayed by ELISA using commer- cial kits (Diagnostic Bioprobes, Italy). The serum concentrations of anti-CagA antibodies were expressed in arbitrary units (Uarb/mL) as no international standard is available. According to the manufacturer’s guidelines, a cut-off value of 5 Uarb/mL was used to discriminate negative from positive samples. The se- rum concentrations of anti-H. pylori and anti-CagA antibodies were expressed as mean and standard error (SE). Statistical analysis Differences in variables were analysed using analysis of variance, t-test, Mann– Whitney U test, Kruskal–Wallis test طسوتلما قشرل ةيحصلا ةلجلماشرع سداسلا دلجلما شراعلا ددعلا 1041 and Chi-squared test as appropriate, and P-values < 0.05 were considered significant. All the available data were analysed using SPSS, version 15.0. Results Baseline characteristics Baseline characteristics of the partici- pants are shown in Table 1. The patient and control groups were similar in age and male/female ratio, but patients had significantly higher prevalence of clas- sic risk factors for IHD (hypertension, dyslipidaemia and diabetes) compared with the control group. Anti-H. pylori IgG seropositivity The overall seroprevalence of anti- H. pylori IgG was 89.2% among patients with IHD and 58.3% among healthy controls with mean titre 45.58 U/mL (SE 4.58) and 25.72 U/mL (SE 4.01) respectively. The prevalence of anti- H. pylori IgG was significantly higher in IHD patients compared to the control group (P < 0.0001). The mean titre of anti-H. pylori antibodies in the IHD group was significantly higher than that observed in the control group (P < 0.01) (Table 2). The seropositivity rate of anti-H. pylori antibody was 86.7% and 91.7% in the AMI and UA groups with mean titre of 33.2 U/mL (SE 4.76) and 57.96 U/mL (SE 7.54) respectively. The seroprevalence of anti-H. pylori antibodies in AMI and UA groups was also significantly higher compared to the control group (P < 0.0001). The mean titre of anti-H. pylori antibodies in AMI and UA groups was significantly higher than that observed in control group (P < 0.05 and P < 0.001 respectively). The seroprevalence of anti-H. pylori was similar in patients with AMI and UA. No significant difference was observed between the AMI and UA groups re- garding the mean titre of anti-H. pylori antibodies (Table 2). Anti-CagA seropositivity The overall seroprevalence of anti-CagA IgG was 60.7%in H. pylori-infected pa- tients with IHD and 65.7% in infected asymptomatic healthy subjects; mean titres were 37.68 Uarb/mL (SE 8.35) and 16.84 Uarb/mL (SE 2.88) respec- tively. There was no significant differ- ence between IHD and control groups regarding the prevalence of anti-CagA antibodies. There was no significant difference between IHD and control groups regarding the mean titre of se- rum anti-CagA antibodies, although this parameter was higher in the IHD group in comparison to asymptomatic healthy subjects. The seropositivity rate of anti- CagA antibody was 55.8% and 65.5% in H. pylori-infected patients with AMI and UA respectively; mean titres were 42 Uarb/mL (SE 15.42) and 33.61 Uarb/ mL (SE 7.32) respectively (Table 2). Statistical analysis showed that the differences for both seroprevalence and mean titre of anti-CagA antibodies were not significant between the AMI and UA groups compared to the control group. The prevalence and the mean titre for anti-CagA antibodies were similarly expressed in patients with AMI and UA (Table 2). Discussion In this study the seroprevalence of anti-H. pylori IgG and the mean titre of anti-H. pylori antibodies were signifi- cantly higher in patients with IHD com- pared to the healthy control group. The seropositivity rate for H. pylori infection varies greatly between studies (Table 3). Moreover, the association of H. pylori with IHD may also differ between countries or even within a country. The discrepancies may be attributed largely to differences in age, socioeconomic status, race and ethnic background. Moreover, different inclusion criteria of patients and controls used in the various studies, differences in the distribution of traditional risk factors of IHD and genetic heterogeneities of H. pylori may account for some differences. Accord- ingly, the results of one study may not necessarily apply to other populations, even within the country. H. pylori infection might partici- pate in IHD pathogenesis via direct or indirect effects. The presence of H. pylori DNA has been demonstrated in the aortic tissues and atherosclerotic plaques of the majority patients with coronary heart disease, which could be an important indication of the direct role of bacteria in the pathogenesis of disease [19]. Accordingly, H. pylori can directly provoke inflammation within the atherosclerotic plaques.

EMHJ • Vol. 16 No.10 • 2010 Eastern Mediterranean Health Journal La Revue de Santé de la Méditerranée orientale 1042 Our results showed no significant differences between patient and con- trol groups regarding the prevalence of serum anti-CagA antibodies, which in- dicates that CagA-positive strains were not more related to IHD in comparison to CagA-negative strains. However, the results of a systematic meta-analysis confirm the hypothesis that infection with CagA-seropositive strains is signifi- cantly associated with susceptibility to coronary heart disease [20]. The con- troversial results of some studies regard- ing the association of CagA status of H. pylori with IHD have been summa- rized in Table 4. It has also been reported that there is wide geographical variation in the genotype of CagA+ strains [24]. Moreover, the polymorphisms in genes encoding for some cytokines such as IL-1, TNF-α and IFN-γ have been associated with H. pylori-related dis- eases such as gastric cancer and peptic ulcer [25]. Accordingly, it seems that both host and bacterial factors may account for these differences. Further studies on the interaction between H. pylori and the host genotype, which in turn could determine the intensity of the inflammatory responses, may ex- plain the development of IHD in some H. pylori-infected subjects. Consistent with our findings in the present study, we recently observed that serum concentrations of hs-CRP were not affected by the expression of bacterial CagA virulence factor [26]. However, in our previous study in the same population, an important asso- ciation was observed between infection with CagA-positive H. pylori strains and peptic ulcer [27], which indicate that the role of the CagA-positive strains may differ in peptic ulcer and IHD pathogenesis. We have demonstrated that the mean titre of anti-H. pylori antibodies in patients with IHD was significantly higher than that observed in a control group. Moreover, the mean serum lev- els of anti-CagA antibodies were higher in patients than controls, but the differ- ences were not statistically significant. Recently, cross-reactivity between rab- bit serum with high levels of anti-H. py- lori and antigens from atherosclerotic carotid arteries has been demonstrated [28]. It has been also shown that anti- CagA antibodies are capable of reacting with both bacterial CagA and proteins present in the wall of arteries, provid- ing evidence of molecular mimicry between CagA and vascular antigens [29]. Accordingly, it has been suggested that CagA-positive strains of H. pylori may contribute to the destabilization of coronary atherosclerotic plaques in some patients with acute coronary syn- drome. From these findings, it seems that both anti-H. pylori and anti-CagA antibodies may have an important role in the pathogenesis of IHD. Further prospective studies are needed to assess the relationship be- tween exposure to H. pylori and subse- quent risk of ischaemic heart disease. Because H. pylori infection may be eas- ily eradicated by specific treatments, the accurate definition of this new risk factor may lead to the design of possible novel strategies for the prevention of ischaemic heart disease. Recent studies have highlighted the importance of the Table 2 Association of Helicobacter pylori and CagA in patients with ischaemic heart disease (IHD) compared to the control group Variable Control group IHD group AMI group UA group Seroprevalence of anti-H. pylori (%) 58.3 89.2*** 86.7*** 91.7*** Serum anti-H. pylori (U/mL) [Mean (SE)] 25.72 (4.01) 45.58** (4.58) 33.2* (4.76) 57.96*** (7.54) Serum anti-CagA (Uarb/mL) [Mean (SE)] 16.84 (2.88) 37.68 (8.35) 42 (15.42) 33.61 (7.32) °*P < 0.05; **P < 0,01; ***P < 0.001 compared to control group.

Fouda 2 ABSTRACT This study evaluated peripheral eosinophil and serum eosinophilic cationic protein (s-ECP) levels as markers of asthma control. A total of 38 children with asthma (16 controlled and 22 partially controlled) were compared with 16 age- and sex-matched healthy children. Total asthma cases had higher eosinophil counts and s-ECP levels than healthy children and partially controlled asthmatics had significantly higher levels of both markers than controlled asthmatics. Controlled asthma cases showed non-significant changes in both parameters versus healthy children. A negative correlation was noted between degree of asthma control and both eosinophil counts and s-ECP levels (r = –0.60 and –0.75 respectively). s-ECP as well as peripheral eosinophil count may be helpful in the assessment of asthma control. 1Allergy, Respiratory and Clinical Immunology Unit; 2Department of Paediatrics; 3Clinical Pathology and Immunology Unit, Faculty of Medicine, University of Mansoura, Mansoura, Egypt (Correspondence to M.

Au total, 38 enfants souffrant d’asthme (contrôlé pour 16 d’entre eux et partiellement contrôlé pour 22 autres) ont été comparés à 16 enfants en bonne santé de même sexe et de même âge. Tous les cas d’asthme présentaient un comptage des éosinophiles et un dosage sérique de la protéine cationique de l’éosinophile supérieurs à ceux des enfants en bonne santé ; dans les cas d’asthme partiellement contrôlé, les niveaux des deux marqueurs étaient nettement supérieurs à ceux des cas d’asthme contrôlé. Les cas d’asthme contrôlé n’ont révélé aucun changement significatif des deux paramètres par rapport aux enfants en bonne santé. Une corrélation négative a été observée entre le degré de contrôle de l’asthme d’une part, et le comptage des éosinophiles et le dosage sérique de la protéine cationique de l’éosinophile d’autre part (r = –0,60 et –0,75 respectivement). Le dosage sérique et dans le sang périphérique de la protéine cationique de l’éosinophile peuvent être utiles pour évaluer le contrôle de l’asthme. EMHJ • Vol. 16 No.10 • 2010 Eastern Mediterranean Health Journal La Revue de Santé de la Méditerranée orientale 1046 Introduction Bronchial asthma is a chronic inflam- matory disorder of the airways in which many inflammatory cells have been found to play a role, particularly mast cells, eosinophils and T-lymphocytes [1]. Immunohistochemical techniques have identified higher levels of the CD4+ subset of T-lymphocytes as well as eosinophils in the airways of patients with asthma than in non-asthmatic subjects [2]. The association between eosino- philia and asthma was observed shortly after eosinophils were discovered. In patients with asthma, eosinophils are present in increased numbers in the blood [3], sputum [4] and bronchoal- veolar lavage fluid [5]. After activation, eosinophils can release granulocyte-de- rived proteins, the most toxic of which are eosinophilic cationic protein (ECP) and major basic protein [6]. Clinical research has suggested an emerging clinical usefulness of eosinophil granule proteins as sero- logical makers in the assessment and management of asthma, of which ECP has been most widely characterized and researched [7,8]. We hypothesized that the degree of eosinophilic expression in the blood and the serum ECP (s-ECP) level may be correlated with the degree of asthma control. Accordingly the aim of our work was to evaluate the levels of asthma control in relation to serum eosinophil counts and s-ECP levels. Methods This was a case–control, cross-sectional study of children attending a hospital in Mansoura, Egypt. Sample The cases were 38 children with atopic asthma who were newly presenting to the Allergy and Respiratory Unit at the University of Mansoura Children’s Hospital, Egypt, from 2002 to 2006. They were defined as asthmatic by the frequency of day and night asthma symptoms and the results of pulmonary function tests (PFT) and as atopic from positive skin prick tests. All were new asthma patients who had not previously received asthma controller medication. A control group of 16 healthy children matched by age and sex was chosen from among attendees at outpatient clinics who came for routine vaccina- tion or regular check-ups. According to the degree of severity of asthma on presentation, patients were given asthma controller medication based on the 2006 Global Initiative for Asthma (GINA) guidelines for asthma management [9]. Patients received in- haled corticosteroids (fluticasone-HFA/ metered dose inhaler) 100 µg daily plus short-acting ß-2 agonists (salbutamol inhaler) as rescue medication. After receiving controller treatment for 1 month, patients were categorized into controlled and partially controlled cases based on GINA criteria [9]. Con- trolled cases were those who had a fre- quency of daytime asthma symptoms or use of rescue medication twice or less/ week; suffered no limitation of activities, no nocturnal symptoms and no asthma exacerbations; and had normal PFTs. Partially controlled cases were those who had a frequency of daytime symp- toms or use of rescue medications more than twice/week; suffered any restric- tion of activities, nocturnal symptoms or asthma exacerbations; and PFTs showing forced expiratory volume in 1 s (FEV1) < 80% predicted. Only atopic asthmatic patients with a positive skin test were included in the study. Patients with negative skin prick test, those on controller medications that did not comply with GINA guide- lines (particularly oral corticosteroids) or who presented with severe exacerba- tion were excluded from the study. Informed written consent was ob- tained from all participants before inclu- sion in the study, which was approved by Mansoura institutional review board. Data collection Skin-prick tests were performed only on the asthma cases at initial assessment to differentiate atopic from non-atopic asthmatics using various antigens, in- cluding 2 types of house-dust mite, cat and dog epithelial cells and mould and pollen antigens (Omega), together with negative (saline) and positive (0.5% his- tamine hydrochloride) controls. Wheal size was measured after 15 minutes [10]. A positive reaction was defined as a wheal larger than 3 mm [11]. Children were considered atopic if they had at least 1 positive skin-prick test response. Pulmonary function tests such as FEV1, peak expiratory flow rates (PEF%, PEF25%, PEF50% and PEF75%) were done for both cases and controls at the initial assessment as part of diagnosis and after 1 month of controller medica- tions as an evaluation tool for the degree of control. It was performed by a body- plethysmograph (Master Screen Body) for measurement of static and dynamic pulmonary functions. Blood samples were taken for com- plete blood count and determination of peripheral eosinophil counts for both cases and controls. The s-ECP assay was also done for both cases and controls (Immulite ECP, for use on the Immulite and Immulite1000 systems, Siemens) [12]. Statistical analysis SPSS, version 12.0, was used for all anal- yses. Descriptive data included means and standard deviations (SD) in addi- tion to median values. Non-parametric statistical tests were used including Mann–Whitney U-test for comparison of numerical variables and Spearman test for correlations. P-values < 0.05 was considered statistically significant. Results Background characteristics During the study period 62 children newly presented with asthma to the طسوتلما قشرل ةيحصلا ةلجلماشرع سداسلا دلجلما شراعلا ددعلا 1047 outpatient clinic of the Allergy and Respiratory Unit; 12 of them refused to participate in the study, 10 did not meet the inclusion criteria and 2 were lost to follow-up after starting controller medication. Thus, 38 newly presented asthmatic children were enrolled in the study (19 males and 19 females), with a mean age of 10.3 (SD 1.9) years. Based on their response to controller medication and GINA criteria they were divided into controlled (16, 42.1%) and partially controlled asthma cases (22, 57.9%). They were compared with the 16 healthy control children. The PFTs showed significantly lower values in all parameters (FEV1, PEF%, PEF25%, PEF50%, PEF75%) in the total group of asthma cases compared with healthy children. Also, significantly lower PFT values were found for the same parameters in partially controlled compared with controlled asthmatics (Table 1). Eosinophil levels The total group of asthma cases had a significantly higher peripheral eosino- phil count compared with the healthy control group [mean 627.4 (SD 103.4) versus 371.5 (SD 34.3) cells/mm3 respectively] and also a higher s-ECP level than healthy children [mean 51.8 (SD 47.8) versus 13.8 (SD 3.26) ug/L respectively] (P < 0.001) (Table 2). The same was observed comparing the partially controlled asthma cases with the healthy children for peripheral eosi- nophil count [mean 854.2 (SD 92.1) versus 371.5 (SD 34.3) cells/mm3 re- spectively] and s-ECP level [mean 56.2 (SD 57.2) versus 13.8 (SD 3.3) ug/L respectively] (P < 0.001). On the other hand, there were non-significant differences comparing controlled asthma cases with healthy control children for both eosinophil count [mean 396.9 (SD 45.6) versus 371.5 (SD 34.3) cells/mm3] and s-ECP level [mean 20.2 (SD 19.9) versus 13.8 (SD 3.26) ug/L respectively]. There were also significantly higher eosinophil counts in partially controlled asthma cases compared with controlled asthma cases [mean 854.2 (SD 92.1) versus 396.9 (SD 45.6) cells/mm3] and s-ECP [mean 56.2 (SD 57.2) versus 20.2 (SD 19.9) ug/L respectively] (P < 0.05) (Table 2). Testing the correlations of both eosinophil counts and s-ECP levels with degree of asthma control, we Table 1 Background characteristics and respiratory parameters of the study subjects Variable Healthy controls Total asthma cases Partially controlled asthma Controlled asthma (n = 16) (n = 38) (n = 22) (n = 16) Males/females (no.) 6/2 19/19 10/12 9/7 Mean (SD) age (years) 10.8 (2.5) 10.3 (1.9) 10.0 (2.1) 10.0 (1.9) Mild/moderate asthma (no.) n/a 21/17 12/10 9/7 Mean (SD) duration of symptomsa (months) n/a 7 (6) 7 (3) 8 (1) Respiratory parameters Mean (SD) Mean (SD) Mean (SD) Mean (SD) FEV1 (mL) 90.1 (11.5) 75.6 (11.2)c 62.5 (13.5)c,d 88.8 (9.7) PEF% (mL) 87.7 (4.6) 75.3 (10.7)c 63.8 (18.3)c,d 87.7 (4.6) PEF25% (mL) 83.7 (22.4) 62.7 (9.6)c 51.8 (14.4)c,d 73.7 (7.1)b PEF50% (mL) 118.1 (35.2) 62.6 (13.7)c 48.4 (13.9)c,d 76.9 (13.6)c PEF75% (mL) 111.1 (23.1) 51.6 (13.7)c 37.1 (17.8)c,d 66.3 (9.1)c aDuration of asthma symptoms before presentation. bP < 0.05 versus healthy controls; cP < 0.001 versus healthy controls; dP < 0.001 versus controlled asthma cases (non-parametric statistics).

Thus, higher eosinophil counts and s-ECP were correlated with poorer asthma control, with a higher correlation for s-ECP than eosinophil count (Table 3). Discussion Direct measurement of airways inflam- mation using biological markers could potentially refine asthma management. This explains the current research inter- est in measuring levels of exhaled nitric oxide and eosinophil granule proteins especially s-ECP in asthma [13]. This study revealed that both pe- ripheral eosinophil count and s-ECP levels were significantly higher in atopic asthmatics as a group than in healthy Table 3 Non-parametric correlation of eosinophil counts and serum eosinophilic cationic protein (s-ECP) levels of asthma patients versus healthy controls Variable Spearman correlation coefficient (r) P-value Peripheral eosinophil count (cells/mm3) –0.60 < 0.001 Serum-ECP level (µg /L) –0.75 < 0.001 control subjects. On the other hand, both parameters were significantly high- er among partially controlled asthma cases compared with healthy control children as well as controlled asthma cases. Interestingly, however, controlled asthma cases showed non-significant changes in the levels of both parameters versus healthy control children. These higher levels of s-ECP and eosinophil counts in children with uncontrolled asthma may suggest that eosinophil-mediated inflammation is important to investigate in assessing asthma control and in deciding treat- ment regimens. This finding is support- ed by the evidence that eosinophils play an important role in the pathogenesis of asthma and that elevation of peripheral blood eosinophil count is a risk factor for the development of airway remodel- ling and irreversible changes in lung function [14]. This is also supported by the research of Lee et al. who reported that higher levels of s-ECP were associ- ated with more severe exacerbation of asthma followed by a decrease in s-ECP levels with resolution of symptoms [15]. Our work also showed a significant inverse correlation between level of asthma control and both parameters, particularly s-ECP, implying that poorer control is expected with higher s-ECP levels. This will add to the work of Koh et al., who described a correlation between asthma severity and s-ECP level. Thus, considering that s-ECP has been widely investigated as a potential biomarker of airway inflammation, it may have a useful role to play as a control parameter in asthma guidelines [16]. In conclusion, despite the small sam- ple size, this study has demonstrated that s-ECP and peripheral eosinophil counts may have clinical usefulness in assessing levels of asthma control and hence in refining asthma management. Based on these findings, we recom- mend conducting a larger, randomized controlled trial to evaluate the correla- tion between s-ECP level and degree of asthma control and to obtain a cut-off point for s-ECP beyond which a patient may be considered uncontrolled.

All cases with clinical signs and symptoms of VL and positive by the direct agglutination test were referred for physical examination and treatment. The mean annual incidence of VL decreased significantly from 1.88 before (1985–2000) to 0.77 per 1000 child population after the intervention (2001–07). In a control area with no surveillance, it increased from 0.11 to 0.23 per 1000. Early detection of VL using practical serological tests and timely treatment of cases could decrease the mortality and morbidity rates of VL in endemic areas. 1Department of Medical Parasitology and Mycology; 4Meshkin-Shahr Research Station, National Institute of Health Research of Islamic Republic of Iran; 6Department of Epidemiology and Biostatistics, Tehran University of Medical Sciences, Islamic Republic of Iran (Correspondence to M.

Tous les cas présentant des signes cliniques et des symptômes de leishmaniose viscérale ainsi qu’une réaction positive au test d’agglutination directe étaient orientés en vue d’un examen physique et d’un traitement. L’incidence annuelle moyenne de la leishmaniose viscérale a nettement diminué, passant de 1,88 avant l’intervention (1985-2000) à 0,77 pour 1 000 enfants après l’intervention (2001-2006). Elle a augmenté dans une zone témoin sans surveillance, passant de 0,11 à 0,23 pour 1 000 enfants. Un dépistage précoce de la leishmaniose viscérale à l’aide de tests sérologiques pratiques et une prise en charge rapide des cas permettraient de réduire les taux de mortalité et de morbidité de la leishmaniose viscérale dans les zones endémiques. طسوتلما قشرل ةيحصلا ةلجلماشرع سداسلا دلجلما شراعلا ددعلا 1051 Introduction Visceral leishmaniasis (VL)—caused by Leishmania infantum LON-49 (GenBank accession no. EF653268) in human and animal reservoirs—has been reported from different parts of the Islamic Republic of Iran [1,2]. In recent decades, VL has become an important endemic disease among rural and semi- nomadic populations in the north-west of the country [1]. In a longitudinal, cross-sectional seroepidemiological study carried out during 1996–2006, a total of 32 855 human serum samples were collected from 4 geographical zones of the Islamic Republic of Iran; 3574 samples (10.9%) were positive at titres of ≥ 1:3200. Almost 43% of the samples were collected from Meshkin- Shahr and Moghan districts in Ardebil province in the north-west of the coun- try [3], an area where health facilities are not well-established and VL often coexists with brucellosis, tuberculosis and other infectious diseases. Moreover, 99.4% of the VL cases were in children under 12 years of age. A VL surveillance system for active and passive case-finding was set up in the villages of Meshkin-Shahr district in 2001 to carry out early detection in children aged under 12 years in the primary stage of infection using sero- logical methods [4] and to treat infected individuals promptly to decrease the mortality and morbidity rates of the disease in endemic areas. In the present study, the incidence of VL in children in the intervention area was compared before and after the intervention and in a control area where the surveillance system was not established. Methods Study design In this longitudinal study a VL surveil- lance system was established for chil- dren ≤ 12 years old in Meshkin-Shahr district (intervention area) in 2001. The annual incidence of VL in children of this age group was compared over 2 periods, before (1985–2000) and after the intervention (2001–06). In order to control for ecological changes or chang- es in living facilities that might affect the VL incidence rate, an endemic area adjoining Meshkin-Shahr was selected where a VL surveillance system was not established, Ahar district (control area). The annual incidence of VL in this area was similarly compared over the period for which relevant data were available, both before (1992–2000) and after the intervention (2001–06) and with the incidence in the intervention area. Study area Meshkin-Shahr district is located in the north-west of the Islamic Republic of Iran. It covers an area of approxi- mately 1530 km2 and its population is estimated to be 237 585, among whom 29.7% are settled in urban areas and 70.3% live in 323 rural areas. Meshkin- Shahr is an important endemic focus of VL in the Islamic Republic of Iran and several VL studies have been conducted in this area [5,6]. The control villages in Ahar district have similar ecology and socioeconomic characteristics to the Meshkin-Shahr villages. Health services in the study areas are delivered through the district health net- work, consisting of a local hospital and a few health centres in the city, and health centres with health houses in rural areas. The health house (khaneh behdasht) is the first level of rural health services and covers several satellite villages with simi- lar cultural and social characteristics to a range of about 1500 m. One of the most important activities of health workers (behvarz) in the health houses is local disease control and data collection. The second level is the rural health centre (RHC) situated in a village and covering a population up to 7500. It is run by a medically trained doctor (usually a general physician). The main functions of the RHC are to provide backup services to rural health houses, offer diagnostic and treatment services to cases referred by the behvarz and refer those needing more specialist care to the district health centre (DHC) or district hospital. The third level in the rural health network is the DHC, which is mainly concerned with the supervision and co- ordination of the activities of RHCs and liaison with more specialized district hospitals. The data for this study were col- lected by trained behvarz in the health houses, trained technicians in the RHCs and medically trained physicians in the DHC and district hospitals. Sample collection There were around 100 behvarz during 2001–07 serving an average popula- tion of Meshkin-Shahr of 179 000 with 29 868 children aged ≤ 12 years . In the control area there were 117 behvarz for an average population of 237 585 and 23 062 children ≤ 12 years. The behvarz of all health houses in Meshkin-Shahr district were trained to recognize and refer all suspected cases of VL to an RHC. Finger-prick blood samples were collected onto filter paper by the behvarz from children who were suspected of having VL, i.e. if they had all 3 of the clinical symptoms: abdominal distension, paleness and fever of at least 2 weeks duration [5,7]. In Meshkin- Shar districts where the number of VL cases was high, active case-finding and investigation of the animal reservoir hosts, particularly stray and owned dogs, were also carried out. The blood samples were sent first to the RHC then to the local VL laboratory in the DHC where they were tested us- ing the direct agglutination test (DAT) by trained technicians. Seropositive pa- tients were referred to a paediatrician or general physician in the only hospital in Meshkin-Shahr city for further physical examination and treatment. Some chil- dren were referred to private or public physicians in Meshkin-Shahr. In some cases, bone marrow aspirates were also EMHJ • Vol. 16 No.10 • 2010 Eastern Mediterranean Health Journal La Revue de Santé de la Méditerranée orientale 1052 obtained for the detection of Leshmania spp. from patients with clinical signs and symptoms of VL but with no positive DAT results. All confirmed cases, i.e. those with positive DAT and clinical manifestations of VL (fever, paleness, anaemia, splenomegaly and hepatome- galy), were referred to the DHC to re- ceive appropriate treatment. Pentavalent antimony in meglumine antimoniate (Glucantime, Rorer Rhone-Poulenc Specia, Paris, France) was administered intramuscularly at 20 mg/kg body weight daily for 21–28 days. Since, the VL surveillance system had not been set up in the control area, the incidence was estimated from clini- cal features, response to the treatment and occasionally DAT (only in sympto- matic patients). DAT antigen preparation and serological tests DAT was developed as a simple, reli- able, cost-effective tool for diagnosis and epidemiological surveys of VL in human and canine reservoirs in the Islamic Republic of Iran [3,4,8–10]. DAT Leishmania antigen was sup- plied by the Protozoology Unit of the Department of Medical Parasitology and Mycology at the School of Public Health, Tehran University of Medical Sciences [3,10]. All the collected serum samples were tested by DAT. Initially, for screening purposes, 2 dilutions of serum samples (1:800 and 1:3200) were tested with Leishmania antibod- ies. If both of these dilutions were positive, samples with titres 1:800 were diluted further to give endpoint titres of 1:102 400. Control wells with negative serum samples and known negative and positive controls were tested on each plate daily. The positive standard control was prepared from the serum of humans with L. infantum infection from the endemic areas, confirmed by microscopy, culture, animal inocula- tion and 1:102 400 DAT titres. A titre of ≥ 1:3200 was used as the cut-off point for human Leishmania infection, as determined in our previous studies [1,3,10]. Statistical analysis The mean annual incidence of VL per 1000 population aged ≤ 12 years old based on positive DAT accompanied by clinical signs and symptoms and relative risk of the disease with 95% confidence interval (CI) were calculated. Data were compared in the periods before and after establishment of surveillance in Meshkin-Shahr villages and with data from the control area. Analyses were done using the chi-squared, t-test and paired t-tests with SPSS software, ver- sion 13.5. P-value < 0.05 was considered statistically significant. Results During 2001–06 a total of 3977 human serum samples were collected from children suspected of having VL in the intervention area. The seroprevalence rate at titres ≥ 1:3200 was 4.15%. Table 1 shows the incidence of VL in children ≤ 12 years old, based on positive DAT and clinical signs and symptoms, in the intervention and control areas before and after the inven- tion started in 2001. The mean annual incidence of VL decreased significantly from 1.88 per 1000 population aged ≤ 12 years in the period before the inter- vention (1985–2000) [5] to 0.77 per 1000 after the intervention (2001–07) (P < 0.001). In the control area, the mean annual incidence of VL increased significantly from 0.11 per 1000 popula- tion aged ≤ 12 years in the period before 2001 (1992–2000) [5] to 0.23 per 1000 in the period after the intervention (2001–07) (P < 0.005). Figure 1 shows the mean annual incidence each year in the interven- tion and control areas for the period 2001–07, i.e. after the intervention. During the intervention period, there were only 2 registered deaths due to VL in the intervention area (including an 8-year-old boy who did not tolerate meglumine antimoniate or amphotericin B), while at least 10 deaths caused by VL were registered in the intervention area before the surveil- lance intervention. The annual mortal- ity rate due to VL in children up to 12 years in the intervention area decreased significantly from 0.16 per 1000 before to 0.009 per 1000 population aged ≤ 12 years after the intervention (P < 0.001). About 20 deaths due to VL in children up to 15 years old were registered in the control villages during this period.

Despite the evidence from experimental studies of a decreased incidence of ZVL in both dogs and children following serological screening of dogs and killing of seropositive animals, the efficiency and acceptability of control strategies for ZVL are still debated [13,14]. Treat- ing infected dogs is not an effective control strategy, as relapses are frequent and dogs can regain infection weeks after treatment, despite showing clinical cure [15]. Moreover the widespread veterinary use of VL drugs might lead to the development of resistant strains of the parasite. A new control approach is the use of deltamethrin-treated collars, which reduced the risk of infection in dogs by 54% and in children by 43% in a study conducted in the Islamic Republic of Iran [16]. Anti-leishmanial vaccines are unfortunately not yet available [17]. Although phlebotomine sand-flies are still susceptible to insecticides, unfor- tunately the disease quickly re-emerges when the spraying campaigns are dis- continued. Therefore early case-finding and treatment of VL is still an essential component of reducing VL mortality and morbidity rates [18]. Our findings showed that mean an- nual incidence of symptomatic cases of VL decreased significantly from 1.88 per 1000 to 0.77 per 1000 in children ≤ 12 years old in the periods before and after the intervention respectively, whereas in the control villages, the mean annual incidence of the disease increased significantly from 0.11 per 1000 to 0.23 per 1000 respectively. Our results suggest that establishment of a VL surveillance system can decrease the incidence of VL. A pilot study to control VL in the focus of Meshkin-Shahr carried out by Nadim et al. in 1991–92 showed that this combined method for control of ZVL (case detection, destruction of stray dogs as well as seopositive owner- ship dogs, vector control and public health education) was very effective in this area [unpublished report to WHO Special Programme for Research and Training in Tropical Diseases (TDR), project no: 910191]. Although early detection of VL in humans is effective in prevention of death due VL and in reducing the incidence of the disease, it cannot completely eliminate the dis- ease by stopping the transmission cycle. Mohebali et al. showed that 14.2%) of domestic dogs in the villages of endemic areas of the Islamic Republic of Iran were positive by DAT [2]. Furthermore, the type of construction of houses in vil- lages and the semi-nomadic life of part of the population play an essential role in the transmission cycle of VL. As the clinical manifestations of VL have low specificity, confirmatory tests are required to decide which patients should be treated. Such tests should not only be highly sensitive—as VL is a fatal condition—but also need to be highly specific because the current drugs used to treat VL are toxic [12]. DAT has been specifically developed for field use and has been extensively validated in most endemic areas [8,9]. Thirty studies were included in a recent meta-analysis, which gave sensitivity and specificity estimates for DAT of 94.8% (95% CI: 92.7%–96.4%) and 85.9% (95% CI: 72.3%–93.4%) respectively [19]. In our study, we used DAT to support the VL surveillance system because it is simpler than many other tests and suitable for field activities. It should be noted that a positive DAT result in endemic areas must be combined with specific clini- cal manifestations of VL such as mild fever (at least 2 weeks), paleness and anaemia, splenomegaly, hepatomegaly and lymphadenopathy to be considered as VL [5]. We faced some challenges in carry- ing out routine serological testing due to variations in different batches of DA an- tigen, the lack of a cold-chain supply for transport of antigen, the need for serial dilutions of blood or serum samples and also the relatively long incubation time (18 hours) for reading the test results. A variant of DAT—the fast agglutination screening test—is very practical under field or rural conditions, and can be used in the future to screen large populations Figure 1 Mean annual incidence of visceral leishmaniasis (VL) per 1000 children aged ≤ 12 years in the intervention area (Meshkin-Shahr district) and control area (Ahar district) after establishment of the VL surveillance system EMHJ • Vol. 16 No.10 • 2010 Eastern Mediterranean Health Journal La Revue de Santé de la Méditerranée orientale 1054 References Edrissian GhH.

Daboul1 ABSTRACT Neutrophils are always present in the cytomorphologic process of leishmaniasis but their role is still not fully understood. Microscopic examination was done on smears from 56 cases of clinically diagnosed cutaneous leishmaniasis. Neutrophils were the predominant cells in the smear (>35% of the total cell count including neutrophils, macrophages and lymphocytes) in 7% of cases, a minority (10%–35% of total cells) in 36% of cases and rare (< 10% of total cells) in 57% of cases. Microscope images confirmed that neutrophils appeared to have an important role in leishmania elimination through phagocytosis of amastigotes in the later stages of the disease process. 1Daboul Medical Laboratory, Damascus, Syrian Arab Republic (Correspondence to M.W.

EMHJ • Vol. 16 No.10 • 2010 Eastern Mediterranean Health Journal La Revue de Santé de la Méditerranée orientale 1056 Introduction Cutaneous leishmaniasis is endemic in over 70 countries, with an estimated annual incidence of 1.5 million cases [1]. Neutrophils are always present in the cytomorphologic process of leishmaniasis, but their role is still not fully understood. Polymorphonuclear (PMN) neutrophils have been reported to have a crucial role in the destruction of the Leishmania major parasites at an early stage of infection [2,3]. A rapid and sustained neutrophilic infiltration local- ized at the site of the sand-fly bite has been observed using dynamic intravital fluorescence microscopy and flow cy- tometry [4]. Studies showing that PMN neutophils are present in vivo at the sites of the lesion and can kill the parasites in vitro have suggested that these cells might be involved in inhibiting multi- plication of the parasite. Neutrophils also appear to play a major role in the development of protective immunity [5,6]. One study with C57BL/6 mice demonstrated that the interaction of L. major-infected macrophages with dying neutrophils induced parasite destruction mediated by neutrophil elastase and tumour necrosis factor-α production from neutrophils [5]. Most of these studies focused on the very early stages of infection; little has been mentioned about the role of neu- trophils in the later stages of cutaneous leishmaniasis. The pathological features in the later stages of the disease indicate a gradual decrease in the number of amastigotes and macrophages, leaving a granulomatous infiltrate consisting of lymphocytes, epithelioid cells and multinucleated giant cells. At this stage it is difficult or even impossible to detect the amastigotes in haematoxylin and eosin or Giemsa-stained sections [7]. In a dry nodular type of lesion, there is a tendency to form granuloma with fewer lymphocytes and scanty plasma cells [8]. Previous studies have not claimed any role for neutrophils or demonstrat- ed the appearance of neutrophils during the late stages of the disease process, although they mention the disappear- ance of the amastigotes without giving any rationale for their disappearance. This cytomorphological study of the role of neutrophils in cutaneous leishmaniasis aimed to investigate the appearance of neutrophils together with the phagocytosis function on the amas- tigotes in infected lesions from humans with cutaneous leishmaniasis at a later stage of the disease. Methods The sample for the study was all 56 cases of cutaneous leishmaniasis (50 males and 6 females) referred for investigation to a medical laboratory in Damascus, Syrian Arab Republic over the period October 2006 to February 2008. All the cases were clinically diagnosed as cuta- neous leishmaniasis by an expert der- matology consultant at a dermatology clinic in Damascus. All cases referred over the time period were included and the stage of the disease had not been determined. Two microscope slides were pre- pared from each patient, stained with Wright stain and examined under the microscope at × 400 magnification. A total of 50 fields were studied in each slide and the neutrophil, phagocyte and lymphocyte counts per field were noted. For each case the cell counts were calcu- lated as mean percentages. For each case the neutrophils were defined as: +++ if they constituted > 35% of the different cells microscopically present in the smear including macro- phages and lymphocytes; ++ if they were between 10% and 35% of total; or + if they were < 10% of the total. The presence of amastigotes in the smear was noted in relation to the neu- trophils cell counts. Results Table 1 shows the neutrophil counts as a percentage of the total neutrophils, phagocytes and lymphocytes in the microscope slides. Neutrophils were present in a high concentration among the 3 cell types (neutrophils, lym- phocytes and phagocytes) in only 7% of the cases studied, while in 93% of cases neutrophils were not the predominant- cells in the slides and in 57% of cases neutrophils were rarely seen (< 10%).

When the amastigotes were heavily concentrated in the extracellular fluid, the neutrophils were more concentrated, while when the amastigotes were present intracellu- larly with very low appearance in the ex- tracellular fluid, the neutrophils showed low presence (0%–35%) among the cells and when the amastigotes disap- peared from the screen, the neutrophils had very low counts in the microscope slide (< 10%). It appears from the sample micro- scope images that once the neutrophils became the predominant cell type in the field, their function in phagocytosis of the amastigotes becomes apparent (Figures 1 and 2). When the neu- trophils were in lower concentrations, phagocytosis of amastigotes was not seen (Figure 3). The greater appearance of neutrophils when the amastigotes were present in the extracellular fluid, as shown in the cell counts, is evident in Figure 4. Discussion The cases in this study were referred with clinical signs of cutaneous leishma- niasis and no definite disease stage was determined for any of them. We can as- sume that none of the cases were at the very beginning of the disease process (as presented in other studies [2–4]) as studies indicate that no immediate clinical symptoms appear at the very early stage of the disease soon after the sand-fly transmits the parasite to the host [7,8]. When a patient presents clinically with a skin ulcer measuring 2–5 cm in diameter with a wet exudate and the pathological features show a dermal infiltrate mainly composed of macrophages filled with amastigotes, lymphocytes and plasma cells, then this is an early stage of the disease proc- ess. When the lesions clinically appear smaller in size, dry and nodular with dried exudates and the microscopic features show a decrease in the number of, or a disappearance of, the amastig- otes and their macrophages, leaving a granulomatous infiltrate consisting of epithelioid cells, multinucleated giant cells, fewer lymphocytes and scanty plasma cells [7,8], then this is a later stage of the disease process. In the microscope images, neu- trophils are shown phagocytosing the released amastigotes in the extracellular fluid of infected lesions. Neutrophils are believed to be specialized in the phago- cytosis process, while macrophages are considered less efficient than PMN neu- trophils at killing foreign microorgan- isms, and the mechanism is not as well understood [9]. Accordingly, we can as- sume that those PMN neutrophils have a strong role to play in phagocytosis and destruction of amastigotes released after membrane rupture of the infected macrophages. Otherwise it is not pos- sible to explain the disappearance of the amastigotes from the infected tissues after their release in huge numbers into the extracellular fluid later in the healing process of cutaneous leishmaniasis [7]. We can hypothesize that once the amastigotes are released from the ruptured phagocytes into the extracel- lular fluid in the late stage of the dis- ease process, they are recognized by the neutrophils as foreign bodies and an acute-phase reaction is established. More neutrophils are attracted, as seen by an increase in the neutrophil con- centration in the damaged area. The neutrophils start the process of phago- cytosis of the released amastigotes and consequent limitation of disease. In conclusion, this study has found that PMN neutrophil cells were at no time absent from the disease process of cutaneous leishmaniasis, in either the early or late stages. While previous Figure 1 Microscope image shows amastigotes engulfed within the neutrophil Figure 2 Microscope image shows increased neutrophils with phagocytosis activity Figure 3 Microscope image shows fewer neutrophils and more lymphocytes and no phagocytosis function Figure 4 Microscope image shows amastigotes released into extracellular fluid with elevation in the number of neutrophils and phagocytosis activity EMHJ • Vol. 16 No.10 • 2010 Eastern Mediterranean Health Journal La Revue de Santé de la Méditerranée orientale 1058 studies have noted the role of PMN neu- trophils in the early stages of the disease process, this study concentrated on their role in the later stages. The neutrophils seemed to be highly effective in phago- cytosis of amastigotes released from ruptured phagocytes to the extracellular fluid. The PMN neutrophils seemed to establish their role by phagocytosis of the amastigotes as demonstrated by the disappearance of amastigotes when neutrophil counts drop. References Daboul MW.

Al Awaidy,1 S. Bawikar,1 P.K. Patel,2 P. Kurup,3 G.S. Sonal,4 S. Al Mahrooqi1 and R. Ramzy1 ABSTRACT The endemicity status of lymphatic filariasis in Oman is uncertain, with only sporadic cases reported, mostly imported. Immunochromatographic card test surveys were carried out to assess the presence of circulating Wuchereria bancrofti antigenaemia as a marker for active infection in children from suspected high-risk areas of Oman (South Batinah and Dhofar). Lot quality assurance sampling surveys were carried out on a minimum of 250 secondary-school children aged 17–18 years in each of 8 districts from February 2004 to March 2004. All tested students were negative for circulating W. bancrofti antigen. Based on these findings as well as previous data, Oman may possibly be classified as a nonendemic country, with no evidence of indigenous lymphatic filariasis transmission. 1Department of Communicable Disease Surveillance and Control, Ministry of Health, Muscat, Oman (Correspondence to S.T.

Des études fondées sur des tests immunochromatographiques sur carte ont été effectuées pour déterminer la présence d’antigènes circulants spécifiques de Wuchereria bancrofti, en tant que marqueur d’une infection active chez les enfants dans les régions suspectées de présenter un haut risque à Oman (Batinah-sud et Dhofar). Un sondage pour le contrôle de la qualité des lots a été réalisé sur un minimum de 250 élèves de l’enseignement secondaire âgés de 17 à 18 ans, dans chacun des huit districts entre février et mars 2004. Tous les élèves testés présentaient des résultats négatifs pour l’antigène circulant spécifique de W. bancrofti. En fonction de ces résultats et de données précédentes, Oman peut être classé comme un pays non endémique ne présentant aucun signe de transmission indigène de la filariose lymphatique. EMHJ • Vol. 16 No.10 • 2010 Eastern Mediterranean Health Journal La Revue de Santé de la Méditerranée orientale 1060 Introduction Lymphatic filariasis (LF) is one of the most debilitating, disfiguring and stig- matizing diseases of the tropical and subtropical regions of the world. LF is endemic in more than 80 countries. It is estimated that 120 million people are infected and one-third of them suf- fer from chronic manifestations of the disease. Worldwide, an additional 1 bil- lion individuals are at risk of acquiring the infection [1–4]. The World Health Organization (WHO) estimates that 5.1 million disability-adjusted life years (DALYs) are lost due to LF [5]. Estimates suggest that approximate- ly 12.6 million LF-infected individu- als, 1% of the LF global burden, live in countries of the Eastern Mediterranean Region, where LF is entirely caused by Wuchereria bancrofti and is transmitted primarily by Culex spp. mosquitoes in mostly rural and semi-urban areas [6]. LF is endemic in Egypt, Sudan and Yemen and is targeted for elimination under the Global Programme for the Elimination of Lymphatic Filariasis (GPELF) [7]. The LF situation in Dji- bouti, Oman, Pakistan, Saudi Arabia and Somalia is currently described as uncertain. However, clinical cases have been reported from Oman, Pakistan, Saudi Arabia and Somalia [4,7]. Oman has a population of approxi- mately 2.34 million, of whom 23.9% are expatriates (2003 census data). Many of these expatriates are from LF- endemic countries such as Egypt, India and Sri Lanka. LF is a notifiable disease in Oman, and between 1991 and 2001 15 cases were reported, mostly classified as imported based on the history of the patient’s stay in LF-endemic countries. Of these, 7 were Omanis who lived for some time in LF endemic areas [6,8]. With such sporadic cases it is necessary to verify the LF status of Oman. A study conducted by Scrimgeour et al. found an LF antigenaemia prevalence of 4.2% based on the immunochromatographic test (ICT) among Indian expatriates living in Oman [9]. However, in the global perspective, Oman is included among countries with an uncertain LF situation, i.e. there is no clear evidence either of the presence or absence of local transmission [6]. The ICT filariasis card test is a rapid format test that detects circulating filarial antigens released by adult worms [10] and can thus detect active infec- tion independent of microfilaraemia. Several field studies have evaluated the rapid test and showed that the ICT test can use blood collected during the day or night; the sensitivity of the test reached 98%–100% among microfilaria carriers with 100% specificity [11–14]. Therefore, WHO has recommended the use of the ICT card test for mapping LF endemic areas [15]. The present study aimed to evaluate the LF status in Oman by carrying out ICT-card surveys to detect W. bancrofti antigenaemia among secondary-school children aged 17–18 years in these 2 regions. Methods Study design This was a lot quality assurance sam- pling (LQAS) school-based survey conducted during the academic year 2004–05 among secondary-school children from areas identified as having the potential for LF transmission. Study area The process of verification included initial use of qualitative methods (ques- tionnaire surveys of key informants) to identify possible LF endemic areas. This was followed by LQAS antigenaemia surveys in these possible endemic areas. The key informant surveys identified 2 possible LF endemic areas: South Batinah and Dhofar region (adminis- tratively described as the governorate of Dhofar). Initial rapid assessment question- naire surveys had revealed that the probability of local transmission was highest in the 6 districts of South Bati- nah region and 2 districts representing 81% of the population in the Dhofar governorate. Hence, the current antigen surveys were conducted in these 8 dis- tricts of 2 regions of Oman. Study population The target population was children aged 17–18 years attending secondary schools. The rationale for selecting this age group for the surveys was that LF is a chronic disease with a long incubation period that requires repeated exposure over an extended period of time be- fore the infection is acquired. It takes even longer for the clinical signs and symptoms of lymphatic obstruction to appear. Therefore, the secondary- school students of this age group would offer epidemiological evidence of the presence or absence of indigenous LF infection in Oman because they would represent an exposure history of 17–18 years. Sampling The WHO guidelines for preparing and implementing a national plan to eliminate LF require that LQAS surveys are conducted to assess the prevalence of antigenaemia in a district to decide on initiation of mass treatment. Thus it was decided that a sample of 250 children from the target age group from each district would be examined using ICT. A cut-off point of 1% was set to classify the district as endemic for LF [16]. Out of 6 districts from South Bati- nah region 3 districts have a significantly lower population compared with the other 3. Hence, it was decided to test the whole secondary-school population in these 3 districts (295, 235 and 257 students). In the other 3 districts , Barka, Musanah and Rustaq, the selection of the students was done according to the proportional target population. Thus 358, 347 and 506 students were select- ed from these districts respectively, by considering each class in the secondary طسوتلما قشرل ةيحصلا ةلجلماشرع سداسلا دلجلما شراعلا ددعلا 1061 schools as 1 cluster and randomly se- lecting the classes. Similarly, 499 and 248 students were selected from Salalah and Taqah districts of Dhofar region respectively. Survey The field part of the study was conducted from February to March 2004. A field protocol was developed to ensure uniformity and smooth conduct of the surveys and also to ensure quality. A national team was formed to oversee the survey activities including the train- ing of staff. The field investigators were the school health staff, including doc- tors and nurses of the respective district. A standardization training workshop was organized before the field part of the study to detail the survey methodology. All aspects of the ICT kit procedure were explained and demonstrated to the field staff. The staff were given hands-on training followed by a field evaluation of the acquired skills to ensure quality. Each survey team consisted of 1 doctor and 2 staff nurses. One nurse filled the data collection forms while the other collected blood samples and performed the ICT test. The doctor was responsi- ble for reading the card results and over- all quality control. Data were collected onto pre-tested school forms. ICT test kit The NOW ICT filariasis kit (catalog no. 620-000, Binax Inc.) was used for the qualitative detection of W. bancrofti antigen. The tests were developed and read according to the manufacturer’s instructions. The test is useful for the demonstration of the W. bancrofti anti- gen at any time of the day and with any accessible population. A 100 µL blood sample collected by fingerprick during the day was added without pre-treat- ment to a pink and white sample pad coupled to colloidal gold that contained dried polyclonal antibody (PAb) and monoclonal antifilarial antibody (MAb) respectively. The teams were asked to conduct the tests in lots of 10 students to ensure a smooth flow of the test pro- cedures. The results were read after 10 minutes. The test was recorded positive if 2 lines (test and control) were seen in the viewing window, even when the test line appeared lighter or darker than the control line. The test was considered invalid if the control line did not appear; the test was then repeated according to the manufacturer’s instructions. Ethics The study was approved by the Omani Ministry of Health and regional health administrators as well as the Regional Committee of the World Health Or- ganization Regional Office for the East- ern Mediterranean. The students as well as the parents and community at large were briefed about the purpose of the survey. Informed consent was obtained before conducting the survey. Statistics The data were computed and analysed using the statistical program Epi-Info 2000. Frequencies, proportions and prevalence rates were calculated. Results A total of 2745 students aged 17–18 years were subjected to antigenaemia testing with a minimum of 250 students in each of the 8 districts. A total of 1998 (72.8%) were from South Batinah re- gion and the remaining 747 (27.2%) were from Dhofar region. The study subjects were from classes belonging to 34 randomly selected secondary schools in the study areas. The male to female ratio was 0.9:1. Of the 2745 tested, none of the students tested positive for circulating W. bancrofti antigen (Table 1). During the surveys 2 card tests were doubtfully positive in South Batinah region and 14 cards were read as invalid in Dhofar region. These tests were repeated later and also found to be negative. Discussion LF is uncommon in Oman. The en- demicity status is uncertain [6]; how- ever some areas have been suggested as endemic areas [4]. Only 15 cases of LF were reported in Oman during the surveillance period 1991–2001. Most cases were classified as imported [6]. In our LQAS surveys of 2745 sec- ondary-school students in South Batinah region and Salalah and Taqah districts of the Dhofar region, all were uniformly antigen-negative and therefore none of the study districts were LF endemic.

Similar to our study, the prevalence of LF was zero in some studies in Trinidad [16,17]. It is generally believed that the vectors of LF are abundant in Oman, although the specific mosquito species have not been formally identified. Nevertheless, LF is most likely not endemic in Oman. The existence of isolated infected cases in areas where transmission is extremely unlikely (e.g. immigrants from a LF en- demic country to a nonendemic coun- try) does not require development of a national LF elimination programme. Such a situation requires implementa- tion of a passive surveillance system by testing blood routinely collected from military recruits, university students, blood donors and hospitalized patients. Similarly, examination of blood samples from expatriates and treatment of in- fected subjects would also be necessary. Conclusions The prevalence of filarial antigenaemia among students aged 17–18 years in the suspected transmissible areas was zero. From this evidence it can reasonably be concluded that LF is not endemic in Oman and there is no evidence of its transmission. The data suggest that Oman could seek to be awarded a certificate of LF elimination.

Nafi1 ABSTRACT The introduction of a rotavirus vaccine makes it important to determine the need for vaccination in a population. This study in Jordan in 2007–08 determined the incidence and clinical features of rotavirus gastroenteritis among children aged under 5 years admitted to hospital with diarrhoea. Of 148 children, 59 (39.9%) were ELISA-positive for rotavirus in stool samples, predominantly in the age group < 2 years. There was a marginally higher rate of fever in the rotavirus cases than the non-rotavirus cases. The lowest rate of infection was in winter. No deaths were recorded among the rotavirus or non-rotavirus groups. Rotavirus vaccine was not in use in Jordan at the time of the study. 1Department of Paediatrics, College of Medicine, Mutah University, Karak, Jordan (Correspondence to O. Nafi: onafi2000@yahoo.com).

La présente étude réalisée en Jordanie en 2007-2008 a permis d’identifier l’incidence et les caractéristiques cliniques de la gastro-entérite à rotavirus chez les enfants de moins de cinq ans hospitalisés pour une diarrhée. Sur 148 enfants, 59 d’entre eux (soit 39,9 %) avaient un test ELISA positif pour le rotavirus dans les échantillons de selles, principalement dans le groupe d’âge des moins de deux ans. Le taux de fièvre dans les cas à rotavirus était légèrement plus élevé que celui des cas sans rotavirus. Le taux d’infection le plus faible se situait en hiver. Aucun décès n’a été enregistré dans les groupes avec ou sans rotavirus. Le vaccin antirotavirus n’était pas utilisé en Jordanie au moment de l’étude. طسوتلما قشرل ةيحصلا ةلجلماشرع سداسلا دلجلما شراعلا ددعلا 1065 Introduction Diarrhoea diseases are the second most frequent cause of death among young children in the Eastern Mediterranean Region [1,2] and rotavirus disease is the single most important cause of severe gastroenteritis in children throughout the world [3–5]. Globally about 30%–40% of hospitalizations and deaths due to diarrhoea among children under 5 years old, and about 5% of all child deaths, are attributed to rotavirus infection [1,6]. It occurs as a sporadic seasonal form, even as severe gastroenteritis of infants and younger children, mostly in the first 2–3 years of life, with a peak at age 6–24 months [6]. National cause-specific mortality rates range from 439 per 100 000 (Sierra Leone) to less than 1 per 100 000 (50 countries) [6]. Gastroenteritis due to rotavirus is characterized by vomiting, fever and watery diarrhoea, and occasionally leads to severe dehydration and death in young children. Man is the only res- ervoir of infection, and transmission occurs by the faecal–oral route and can be attributed to poor standards of per- sonal and environmental hygiene [7] in both developed as well as develop- ing countries. Seasonal variation in the incidence of the disease has been noted, particularly in temperate climates where it peaks during the cooler months, while in tropical climates cases occur through- out the year [6]. Unfortunately, protective immunity against rotavirus infection is not com- pletely understood, although serotype specific immunity is believed to play a major role [1]. The introduction of a rotavirus vaccine in some parts of the world makes it important to establish the impact of this organism in our popu- lation in Jordan to determine the need for vaccination. The study reported here from south Jordan is part of a national sentinel surveillance programme. The aims of study were to determine the incidence of rotavirus gastroenteritis among children aged under 5 years admitted with diarrhoea to Al Karak hospital and to map some of the clini- cal features associated with rotavirus disease (fever, severity of dehydration, vomiting and duration of illness). Methods A prospective hospital-based study was carried out over 1 year from 1 May 2007 to 30 April 2008. All cases of diarrhoea in children under 5 years old admit- ted to the department of paediatrics of Al-Karak general teaching hospital were recruited for the study. Patients were eligible if they were admitted for treatment of gastroenteritis and this was the primary illness; were aged ≤ 5 years; and had symptoms for < 7 days duration. The exclusion criteria were: age > 5 years; bloody diarrhoea; or symptoms ≥ 7 days duration. Patients with hospital-acquired gastroenteritis were also excluded. Complete clinical examination was carried out and a questionnaire was filled for each child to collect data on demographic characteristics (e.g. age, sex) and clinical presentation (e.g. body temperature, vomiting, dehydration, duration of illness, date of admission). Fever was defined as body temperature ≥ 38 °C at the time of admission. Mild dehydration was diarrhoea and thirst; moderate and/or severe dehydration was depressed fontanel, sunken eyes, dry tongue and loss of skin turgor. The seasons of admission were recorded as: autumn (21/09–20/12); winter (21/12–20/03; spring (21/03– 20/06); summer (21/06–20/09). A stool sample was obtained from each child and analysed for rotavirus, using an enzyme-linked immunosorb- ent assay (ELISA) (IDEIA rotavirus kit, DakoCytomation Ltd) and read with a photometer (Multiskan EX, Thermo Electron Corporation). The data were analysed using SPSS, version 10. Data were presented as simple frequencies and percentages or means. The significance of differences between proportions or means were tested using the chi-squared or t-test respectively, with P < 0.05 as significant. Results Demographic and clinical characteristics of the whole group Data were collected for 148 children with diarrhoea, 87 males (58.8%) and 61 females (41.2%) (Table 1), a male to female ratio of 1.4:1. The age range was 0–60 months, with mean age 12.4 [standard deviation (SD) 11.5] months. The highest number of diarrhoea cases was during the autumn (60%) and the lowest in winter (4%) (Figure 1). Out of 148 cases with diarrhoea 97 (65.5%) children presented with fever and 51 (34.5%) without fever. (Table 2) The mean age of children with fever was 13.8 (SD 13.0) months and with- out fever was 9.8 (SD 7.5) months. A high rate of diarrhoea patients (107, 72.3%) presented with dehydra- tion on admission; only 11 (7.4%) pre- sented with severe dehydration, while the remaining 96 (64.9%) were consid- ered to have mild dehydration. Patients with dehydration were significantly younger than those not presenting with dehydration [mean age 11.0 (SD 9.3) months versus 16.2 (SD 15.5) months] (t = 2.5, P = 0.013). Demographic characteristics of children with rotavirus diarrhoea We found 59 (39.9%) cases were ELI- SA-positive for rotavirus in their stool and 89 (60.1%) were ELISA-negative for rotavirus. The great majority of cases of rotavi- rus diarrhoea (96.6%) were in children < 2 years old and 78.0% were among children aged < 1 year. A total of 39 cases (66.1%) were in males. Children with rotavirus diarrhoea were significantly younger than children EMHJ • Vol. 16 No.10 • 2010 Eastern Mediterranean Health Journal La Revue de Santé de la Méditerranée orientale 1066 with diarrhoea caused by pathogens other than rotavirus [mean 8.8 (SD 6.3) months versus 14.8 (SD 13.4) months] (t = 3.205, P = 0.002). This inverse re- lationship between the age of children with diarrhoea and the incidence of rotavirus infection is shown on Table 1. The highest rate of rotavirus infec- tion was found among patients aged ≤ 6 months (50.0%) and the lowest rate among those aged > 24 months (11.8%). In contrast, the highest rate of diarrhoea caused by pathogens other than rotavirus was among children aged ≥ 24 months (88.2%) and the lowest rate of non-rotavirus diarrhoea was in children aged ≤ 6 months (50.0%) (Table 1). Rotavirus was detected at a higher rate in the stool samples of male (44.8%) than female patients (32.8%), a male to female ratio of cases of rotavirus infec- tion of 1.95 to 1. However, there was no significant association between patient’s sex and rotavirus infection (χ2 = 2.14, P > 0.05)(Table 1). Interestingly the seasonal pattern of diarrhoea, with a greater incidence in the autumn, was more pronounced among the children infected with rotavirus than those without. The highest incidence of rotavirus diarrhoea was during autumn (28%)(Figure 1).

Fever occurred during rota- virus infection at a significantly younger age [8.8 (SD 6.3) months] than in diar- rhoea cases caused by pathogens other than rotavirus infection [14.8 (SD 13.4) months] (t = 3.208, P < 0.05). Severe dehydration was noticed in a slightly higher rate among patients with rotavirus infection, than diarrhoea cases caused by pathogens other than rotavirus (11.1% versus 9.6%); however this was not significant (Table 2). The rate of vomiting was similar tin both groups (Table 2). Outcomes Most of the diarrhoea cases came for management during the first 7 days of illness with a mean duration of illness of 3.1 (SD 1.3) days. All the cases of diarrhoea were treated and cured within the first 15 hours with a mean of 3.1 (SD 2.3) hours. No deaths were recorded among either group. Discussion Diarrhoeal diseases remain a major cause of death in developing countries, especially in preschool children [1,7]. Children under 3 years of age may ex- perience as many as 10 episodes of diar- rhoea per year [7]. Rotavirus is among the most common causes of diarrhoea worldwide [7,8], accounting for 134 mil- lion episodes/year [7,9,10]. Although a vaccine has become available, rotavirus vaccine was not in use in Jordan at the time of the study. Diarrhoeal disease is considered to be the most important cause of infant morbidity in Jordan [11]. Khuri-Bulos and Al-Katib in 2006 concluded that rotavirus was a significant cause of gastroenteritis in Jordanian children regardless of their social background [7]. In the present study the incidence of rotavirus diarrhoea among children in Al-Karak (39.9%) was slightly higher than in the north of Jordan (33%) as detected by Youssef et al. in 2000 [12]. This discrepancy can be attributed to dif- ferences between the populations, vari- ations in the time of the study or to the laboratory tests used. We found a higher incidence higher than that detected in neighbouring countries: 24%, 37%, 35% and 37% in southern Iraq, northern Iraq, Islamic Republic of Iran and Turkey respectively [5,13–15]. The incidence was also considerably higher than 15% recorded in Spain [16]. In contrast, our rate was lower than the prevalence of rotavirus diarrhoea estimated in Saudi Arabia during 2004–05 (86%) [17] and in Turkey in 2005 (63%) [13]. It is also slightly lower than the prevalence of rotavirus diarrhoea in Kuwait (40%) [9]. This variation in the prevalence of rotavirus infection among different areas is probably due to the social habits of the population, e.g. personal hygiene, and/or environmental variations that may be related to growth of rotavirus pathogens particularly in contaminated water [7]. Although no significant association was detected between sex of patients and rotavirus infection in our study, the male to female ratio of cases with rotavirus infection was almost double (1.95:1), which is similar to another study in Jordan (1.85:1) [18], while a ratio of 1.5:1 was found in Bahrain [19]. The reason for this male predominance cannot easily be explained, although it may be due to social factors rather than a higher rate of infection in boys as parents in Arab societies may be more likely to take a male child to hospital than a female child. On the other hand a study in northern Iraq found no sig- nificant association between rotavirus infection and epidemiological charac- teristics, including sex [5]. The great majority of cases of rotavi- rus diarrhoea (96.6%) were in children < 2 years of age, and the mean age of ro- tavirus diarrhoea cases was significantly lower than diarrhoea cases caused by pathogens other than rotavirus (8.8 months versus 14.8 months). This age pattern is consistent with other studies from the region [9,12,13]. Children < 2 years may be more exposed to infection, or the older age group may have been exposed previously to rotavirus and ac- quired some immunity against infection [7]. Moreover, the mean age of children with rotavirus in our study [8.8 (SD 6.34 months] was lower than that found in northern Iraq [9.3 (SD 8.5) months] [5]. This early exposure of our children may be related to environmental factors such as water contamination [7]. We found an incidence of rotavirus among children aged < 1 year of 45.5% which is similar to the rates of 50% and 30% estimated in Kuwait [9] and Kurdistan respectively [5]. This difference could be related to breastfeeding and weaning times among populations in different areas or countries. There is evidence Table 2 Presenting symptoms of rotavirus-positive and -negative cases in children under 5 years old admitted with diarrhoea Presence of: Rotavirus +ve (n = 59) Rotavirus –ve (n = 89) Statistics No. % No. % Fever 44 75.0 53 59.5 χ2 = 3.62, P = 0.057 Severe dehydration 5 11.1 6 9.6 χ2 = 0.67, P > 0.05 Vomiting 51 86.4 76 85.4 χ2 = 0.038, P > 0.05 EMHJ • Vol. 16 No.10 • 2010 Eastern Mediterranean Health Journal La Revue de Santé de la Méditerranée orientale 1068 that breastfeeding has a protective role in rotavirus-associated diarrhoea [18]. We found that fever was significant- ly associated with rotavirus diarrhoea although we found no other studies with data on fever in rotavirus diarrhoea. Our study demonstrated that the highest incidence of rotavirus diarrhoea was during autumn, followed by sum- mer and spring, while the lowest inci- dence was during winter. This finding contrasts with other studies that found the highest incidence of rotavirus dur- ing winter in Islamic Republic of Iran, Pakistan, Oman and Tunisia (53%, 37%, 60.5% and 40.5% respectively [1]. Simi- larly in Al-Qassim, Saudi Arabia 50% of diarrhoea disease cases found during winter were caused by viruses, and 66% of these were due to rotavirus [20]. A 39.6% prevalence of rotavirus was found in northern Jordan during the summer (1992–93) [21]. In Spain 8% of rota- virus diarrhoea cases occurred during the winter months (January–March) [16]. The peak of rotavirus incidence in the Islamic Republic of Iran, Kuwait and Turkey was during winter [6,9,13]. In contrast to these studies, no seasonal variation was detected in Iraqi Kurdis- tan [5]. These differences may be due to environmental factors that may affect the survival rate of the rotavirus outside the body (temperature, humidity) and to contaminated water or its relation with level of chlorination of water, as rotavirus is inactivated only by chlorine, rather than other disinfectants [7]. Conclusions This study in southern Jordan found rotavirus infection in 39.9% of children < 5 years old hospitalized with diar- rhoea, predominantly in the age group < 2 years. There was a marginally higher rate of fever in the rotavirus cases than the non-rotavirus cases. The lowest rate of infection was in winter. No deaths were recorded among the rotavirus or non-rotavirus group. Whether to introduce rotavirus vaccine to the national immunization schedule is now under discussion in technical health committees in Jordan.

Those most affected are the poorest populations often living in remote, rural areas, urban slums or in conflict zones. With little political voice, neglected tropical diseases have a low profile and status in public health priorities. Although medically diverse, neglected tropical diseases share features that allow them to persist in conditions of poverty, where they cluster and frequently overlap. Over 1 billion people – one sixth of the world’s population – suffer from one or more neglected tropical diseases.

La population de l’étude (4634 patients) était relativement jeune avec une moyenne d’âge de 41,1 ans (écart type [ET] 23,4). La prévalence des infections nosocomiales était de 10,5 % ; celle-ci était plus élevée dans les centres non universitaires et dans les hôpitaux de taille moyenne. Globalement, les infections urinaires étaient les plus fréquentes. Les services de pédiatrie ont enregistré une prévalence particulièrement élevée (11,3 %). Les germes les plus fréquemment isolés étaient Escherichia coli (17,2 %), Staphylococcus aureus (12,5 %), Pseudomonas aeruginosa et Klebsiella pneumoniae (9,2 % chacun). Le jour de l’enquête, 40,7 % des patients étaient sous traitement antibiotique, dont presque la moitié avec une indication empirique. La survenue d’une infection nosocomiale était significativement associée à la ventilation mécanique, un délai de séjour supérieur ou égal à 8 jours, la présence d’un cathéter central ou périphérique, une sonde urinaire, au diabète, et à l’âge. 1Laboratoire d’épidémiologie et santé publique, Université Claude Bernard, Lyon (France) (Correspondance à adresser à K.

The study population (4634 patients) was relatively young, mean age 41.1 (standard deviation 23.4) years. The prevalence of nosocomial infections was 10.5%; this was higher in non-teaching centres and moderate-sized hospitals. Overall, urinary tract infections were the most common. Paediatric departments rated particularly high (11.3%). The most commonly isolated organisms were: Escherichia coli (17.2%), Staphylococcus aureus (12.5%), Pseudomonas aeruginosa and Klebsiella pneumoniae (9.2% each). On the day of the study, 40.7% of the patients were under treatment with antibiotics, with nearly half for an empirical indication. Nosocomial infection was significantly associated with mechanical ventilation, hospitalization ≥ 8 days, presence of a central or peripheral catheter), urinary catheter, diabetes and age. طسوتلما قشرل ةيحصلا ةلجلماشرع سداسلا دلجلما شراعلا ددعلا 1071 Introduction Le s i n f e c t i on s no socom i a l e s représentent un problème de santé publique universel. Mais si la lutte contre ces infections est bien organisée dans les pays développés, elle l’est beaucoup moins dans les pays de faible niveau socio-économique qui souffrent, pour la majorité, d’une absence de réglementation et du manque de données représentatives de surveillance. Les enquêtes de prévalence constituent l’outil de base pour la surveillance des infections nosocomiales. Elles ont même été recommandées par l’Organisation mondiale de la Santé pour des études nationales ou internationales [1]. Elles permettent de faire, de manière simple et à moindre coût, un état des lieux du risque infectieux nosocomial. Cet avantage est encore plus considérable dans les pays de faible niveau socio-économique où les ressources disponibles pour la lutte contre les infections nosocomiales font défaut [2]. De plus, ces enquêtes constituent un outil de sensibilisation et d’information du personnel [3,4]. Dans la région méditerranéenne, peu d’études multicentriques ont été menées sur le sujet. Excepté une étude de prévalence nationale conduite au Maroc en 1994 [5], les autres enquêtes concernant l’infection nosocomiale ont été réalisées à une échelle plus restreinte, souvent au niveau d’un seul hôpital, ce qui rend difficile la possibilité de réflexions communes afin de proposer des solutions cohérentes et efficientes. Autrement, les données des différentes études ne sont pas comparables de façon directe puisque les méthodologies adoptées diffèrent entre elles [6]. Ains i nous avons entrepr is , dans le cadre du réseau NosoMed (Strengthening HealthCare Epidemiology for the Investigation of Nosocomial Infections in the Mediterranean Area), une enquête de prévalence des infections nosocomiales afin de répondre au besoin de faire un état des lieux de l’étendue des infections nosocomiales dans la région méditerranéenne, en incluant un nombre relativement important d’hôpitaux pilotes et en utilisant une méthodologie standardisée et commune à ces hôpitaux. Les objectifs de cette étude étaient de déterminer le taux de prévalence des infections nosocomiales dans des hôpitaux pilotes de la région méditerranéenne, de connaître les sites les plus fréquents de ces infections et leur prévalence, de déterminer les micro-organismes les plus impliqués dans les infections nosocomiales, d’étudier les facteurs de risque liés à ces infections, d’évaluer la consommation des antibiotiques et enfin de sensibiliser le personnel à la gravité de l’infection nosocomiale. Méthodes L’enquête a été conduite dans 27 établissements publics ou privés : quatre établissements en Algérie, dix en Égypte, trois en Italie, six au Maroc et quatre en Tunisie. La participation des établissements était volontaire. Tous les patients admis depuis 48 heures ou plus étaient inclus. Le recueil d’information, par des enquêteurs formés, s’est fait en examinant les dossiers médicaux des patients, ceux des soins infirmiers et les résultats de laboratoire, en plus de l’interrogatoire du personnel, au besoin. Les définitions de l’infection nosocomiale étaient basées sur celles des Centers for Disease Control and Prevention (CDC) [7]. Les données recueillies sur une fiche standardisée ont concerné : l’identification de l’établissement et • du service ; les caractéristiques du patient : • admission, âge, sexe, facteurs de risque intrinsèques (diabète, obésité, dénutrition, immunodépression, neutropénie) ; les facteurs de risque extrinsèques : • sonde urinaire, cathéter vasculaire périphérique ou central, alimentation parentérale, ventilation mécanique, procédure chirurgicale ; l a p ré sence d ’une in fec t ion • nosocomiale : seules les infections actives étaient prises en compte - date du début de l’infection, cultures, résultat microbiologique et résistance pour certains organismes -, deux infections actives pouvaient être notées ; la prescription des antibiotiques : • molécule et indication. Les données ont été validées et saisies localement à l’aide d’une application commune sur Epi Info 6.04. L’ensemble des données a été centralisé au niveau du centre de coordination (laboratoire d’épidémiologie et santé publique à Lyon) et analysé avec le logiciel SPSS V12. L’analyse des facteurs de risque a été effectuée pour l’ensemble des infections nosocomiales et pour les sites les plus fréquemment recensés lors de l’enquête. Une analyse univariée a permis de mesurer l’association des différents facteurs avec la survenue de l’infection nosocomiale (ou des sites d’infection). Cette association a été mesurée à l’aide de l’odds ratio (OR). Les paramètres avec une valeur de p associé au χ2 inférieure à 0,1 ont été introduits dans un modèle logistique afin de déterminer les facteurs de risque indépendants, et la validité du modèle a été évaluée à l’aide du test de Hosmer-Lemeshow. Résultats Caractéristiques des établissements Vingt-sept établissements totalisant 11 853 lits ont participé à l’enquête. Le taux d’occupation des lits par des patients présents depuis 48 heures ou plus était de 39,1 %. EMHJ • Vol. 16 No.10 • 2010 Eastern Mediterranean Health Journal La Revue de Santé de la Méditerranée orientale 1072 Description des patients L’enquête a porté sur 4634 patients. L’âge moyen était de 41,1 ans (écart- type [ET] 23,4) et la médiane de 42 ans ; 19,4 % des patients étaient âgés de 65 ans ou plus. Le sex ratio hommes/ femmes était de 0,99. La durée moyenne de séjour des patients au moment de l’étude était de 15,4 jours (ET 24,3), la médiane se situant à 8 jours. La durée moyenne de séjour la plus élevée était enregistrée en Algérie (20,7 jours, p = 0,02) et la plus faible au Maroc (7,7 jours, p < < 0,001). Les caractéristiques des patients et la présence des facteurs de risque intrinsèques par pays sont présentées dans le tableau 1. Les facteurs de risque extrinsèques sont présentés dans le tableau 2. La présence de facteurs de risque intrinsèques chez les patients issus des hôpitaux égyptiens était plus importante que chez ceux issus des autres pays (différence statistiquement significative pour tous les facteurs de risque cités). Le sondage urinaire, la présence d’un cathéter central et la ventilation étaient plus fréquents chez les patients italiens (p < 10-5), alors que les cathéters périphériques et l’alimentation parentérale étaient plus fréquents en Égypte que dans les autres pays (p < 0,001). Parmi les patients, 1224 (27,0 %) avaient subi une intervention chirurgi- cale pendant l’admission en cours ; 59,5 % d’entre eux avaient un score ASA (American Society of Anesthesiologists) de 1, 25,2 % un score ASA de 2, 10,9 % un score ASA de 3, 3,9 % un score ASA de 4 et 0,4 % un score ASA de 5.

Le taux de prévalence des infections était de 10,5 % (483 infections au total). La moyenne d’âge des patients infectés était de 41,8 ans contre 41,0 ans pour les patients non infectés (différence non significative). La durée moyenne de séjour entre l’admission et l’infection était de 13,6 (ET 25,9) jours (médiane : 6 jours) avec des grandes variations entre les pays allant de 2,6 jours au Maroc à 24,1 jours en Algérie. La durée moyenne de séjour était significativement plus élevée (p < 0,001) chez les patients infectés (24,6 jours) par rapport aux patients non infectés (14,5 jours). Le taux de prévalence des infections nosocomiales était plus faible dans les centres hospitalo-universitaires comparé aux hôpitaux non universitai- res (8,3 % vs 11,0 % ; p = 0,008). Selon la taille des établissements, les hôpitaux de plus de 500 lits rapportaient le taux de prévalence le plus faible (7,6 %), suivis par les hôpitaux de moins de 200 lits (10,6 %), alors que les hôpitaux moyens (200-500 lits) avaient le taux d’infections le plus élevé (12,9 %) (p < 0,001). Le taux de prévalence des patients infectés variait de 6,3 % en Algérie à 11,9 % en Italie. Le tableau 3 présente les résultats par pays. La figure 1 présente les taux de prévalence dans 25 établissements ayant un effectif supérieur à 30 patients inclus.

EMHJ • Vol. 16 No.10 • 2010 Eastern Mediterranean Health Journal La Revue de Santé de la Méditerranée orientale 1074 Sites des infections nosocomiales Les infections urinaires étaient les infections les plus fréquentes : elles représentaient 25,9 % de l’ensemble d e s i n f e c t i on s no so com i a l e s contractées et une prévalence de 2,6 %. L’importance des sites d’infection en termes de fréquence était néanmoins différente entre les pays. Les infections urinaires représentaient presque la moitié des infections nosocomiales en Italie ; elles étaient également en tête en Tunisie, avec la même fréquence que les infections de la peau et des tissus mous. En Égypte, les infections du site opératoire (ISO) étaient les infections prédominantes alors que les infections de la peau et des tissus mous étaient les plus fréquentes en Algérie et les infections respiratoires les plus fréquentes au Maroc (Tableau 4). Infections nosocomiales et spécialité du service Les services de réanimation étaient ceux qui présentaient le taux de prévalence le plus élevé (24,8 %), suivis des services de pédiatrie (11,3 %). Les services chirurgicaux, la gynéco- obstétrique et les services médicaux avaient des taux de prévalence de 8,0 %, 7,7 % et 7,6 % respectivement. En Italie et en Égypte, les infections nosocomiales étaient plus fréquentes dans les services de médecine (11,5 % et 11,6 % respectivement) que dans ceux de chirurgie (8,6 % et 8,4 % respectivement, différence non significative pour les deux). Micro-organismes isolés et résistance aux antibiotiques Pour les 483 infections déclarées, 274 (56,7 %) cultures ont été réalisées dont 230 se sont révélées positives. Au total, 273 germes ont été identifiés. Qua t r e e spèce s b a c t é r i enne s représentaient presque la moitié des germes isolés : Escherichia coli (17,2 %), S t a p h y l o c o c c u s a u r e u s (12 ,5 %) , Pseudomonas aeruginosa (9,2 %) et Klebsiella pneumoniae (9,2 %) ; 31,6 % des S. aureus isolés étaient résistants à la méticilline. La résistance a été également recherchée pour les espèces les plus courantes d’entérobactéries (Enterobacter, E. coli et K. pneumoniae) : 13,5 % des 96 souches isolées étaient sensibles à tous les antibiotiques, 39,6 % étaient résistantes aux aminopénicillines, 14,6 % aux céphalosporines de troisième génération, 5,2 % aux céphalosporines de troisième génération, aux quinolones et aux carbapénèmes. La moitié des 12 A. baumanii identi- fiés étaient résistants aux céphalos- porines de troisième génération, aux quinolones et aux carbapénèmes et un seul était sensible à tous les antibiotiques testés.

Infections nosocomiales et facteurs de risque En fonction de l’âge des patients, le taux de prévalence le moins élevé était enregistré dans la classe d’âge 25-42 ans. Excepté le sexe et l’obésité, tous les autres facteurs de risque, intrinsèques et extrinsèques, étaient significativement associés à une plus grande fréquence d’infection. Un séjour supérieur à huit jours, le sondage urinaire, la présence d’un cathéter central et la ventilation présentaient un OR supérieur à 3. Le sexe féminin a été associé à un risque élevé uniquement pour les infections de la peau et des tissus mous, avec un OR de 1,64 (IC : 1,01-2,68). L’exposition au risque des différents sites infectieux les plus fréquents est présentée dans le tableau 5. Le lien entre les actes invasifs et les sites pour lesquels ils constituent des facteurs de risque particuliers a été retrouvé (sondage et infections urinaires, ventilation et infections respiratoires, cathéter central et bactériémie). Après ajustement, sept variables ont subsisté comme des facteurs de risque indépendants des infections nosocomiales. Elles sont présentées dans le tableau 6. Prescription des antibiotiques La proportion des patients sous antibiotiques le jour de l’enquête était de 40,7 %, avec une indication de prescription empirique dans 40,8 % des cas. Excepté en Tunisie où elle était de 7,7 %, dans les autres pays cette proportion variait de 41,0 % au Maroc à 66,4 % en Égypte ; 17,1 % des patients étaient sous deux antibiotiques ou plus. Les classes d’antibiotiques les plus consommées étaient les pénicillines (32,1 %), les aminoglycosides (15,5 %) et les céphalosporines de troisième généra- tion (14,6 %).

EMHJ • Vol. 16 No.10 • 2010 Eastern Mediterranean Health Journal La Revue de Santé de la Méditerranée orientale 1076 Discussion Cette étude multicentrique sur la prévalence des infections nosocomiales a l’intérêt de produire des données épidémiologiques représentatives du risque infectieux nosocomial dans la région méditerranéenne. Avec une moyenne d’âge des patients de 41,1 ans, la population incluse dans l’étude était très jeune : 15,2 % étaient âgés de 65 ans ou plus dans les pays non européens alors qu’en Italie, seul pays européen participant à cette étude, cette proportion était de 61,5 %. Des proportions supérieures à 50 % des patients âgés de 65 ans ou plus sont rapportées dans toutes les études réalisées dans les pays européens [4,8]. Le taux de prévalence des patients ayant acquis une infection nosocomiale dans notre étude était de 8,9 % et celui des infections de 10,5 %. Ces chiffres se situaient dans la fourchette de ceux rapportés dans la littérature, que ce soit dans les pays européens [3,4,8-10], ou dans les pays sud-méditerranéens [11-14]. Nous tenons à rappeler cependant que la comparaison directe avec les données de la littérature est délicate : taille et activité des établissements, méthodologie adoptée, etc. À titre d’exemple, une étude tunisienne a donné un taux de prévalence des patients infectés de 17,9 % [15], mais l’établissement avait la particularité de posséder un grand nombre de lits appartenant à des spécialités à haut risque (unité de soins intensifs, brûlés, oncologie). Il a été établi par de précédentes études multicentriques que la prévalence des infections nosocomiales augmente avec le niveau de technicité et la taille des établissements [5,8] ; or, dans notre étude, le taux de prévalence des infections nosocomiales était plus élevé dans les hôpitaux non universitaires ainsi que dans les hôpitaux de taille moyenne. Ceci peut être dû en grande partie à des pratiques plus défectueuses et à un manque de règles d’hygiène plus important au niveau de ces hôpitaux mal équipés et peu sensibilisés à la problématique des infections nosocomiales. La fréquence élevée des infect ions nosocomiales en réanimation est régulièrement retrouvée dans toutes les enquêtes de prévalence des infections nosocomiales [5,8,12,15,16]. Elle est associée à une forte fréquence de Ta bl ea u 5 Ex po si ti on a u ri sq ue d es s ite s in fe ct ie ux le s pl us fr éq ue nt s : a na ly se u ni va ri ée Fa ct eu rs d e ri sq ue In fe ct io ns u ri na ir es In fe ct io ns d u si te op ér at oi re In fe ct io ns re sp ir at oi re s Ba ct ér ié m ie In fe ct io ns p ea u/ ti ss us m ou s O R (IC 95 % ) p O R (IC 95 % ) p O R (IC 95 % ) p O R (IC 95 % ) p O R (IC 95 % ) p  ge (< 2 5 ou > 4 2 an s) 1,5 3 (0 ,9 5- 2, 47 ) 0 ,0 8 1,0 9 (0 ,6 4- 1,8 6) 0 ,9 2, 24 (1 ,19 -4 ,2 5) 0 ,0 1 1,5 1 ( 0 ,7 3- 3, 13 ) 0 ,3 1,3 4 (0 ,7 4- 2, 41 ) 0 ,4 Se xe (F ) 0 ,8 5 (0 ,5 8- 1,2 4) 0 .4 1,1 2 (0 ,7 3- 1,8 2) 0 ,6 0 ,9 6 (0 ,6 2- 1,5 0 ) 0 ,9 1,2 1 ( 0 ,6 9- 2, 14 ) 0 ,6 1,6 4 (1, 0 1- 2, 68 ) 0 ,0 5 D ur ée d e sé jo ur ≥ 8 j 3, 92 (2 ,5 3- 6, 0 9) < 10 -1 1 2, 89 (1 ,7 4- 4, 80 ) < 0 ,0 0 1 1,9 8 (1, 26 -3 ,10 ) 0 ,0 0 3 3, 80 (1 ,9 4- 7,4 5) < 0 ,0 0 1 4, 35 (2 ,4 1- 7,8 4) < 0 ,0 0 1 D ia bè te 1,6 8 (1, 0 7- 2, 64 ) 0 ,0 3 1,7 6 (1, 0 3- 3, 0 1) 0 ,0 5 0 ,9 8 (0 ,5 3- 1,8 1) 1 0 ,6 8 (0 ,2 7- 1,7 3) 0 ,5 3, 0 7 (1, 84 -5 ,13 ) < 0 ,0 0 1 O bé si té 2, 11 (1 ,2 1- 3, 68 ) 0 ,0 1 1,5 8 (0 ,7 5- 3, 32 ) 0 ,3 0 ,6 9 (0 ,2 5- 1,8 9) 0 ,7 - 0 ,0 8 0 ,4 1 ( 0 ,10 -1 ,6 9) 0 ,3 D én ut rit io n 1,9 4 (1, 15 -3 ,2 8) 0 ,0 2 1,2 7 (0 ,6 0 -2 ,6 6) 0 ,5 1,5 2 (0 ,7 8- 2, 98 ) 0 ,2 0 ,7 3 (0 ,2 3- 2, 36 ) 0 ,8 1,2 8 (0 ,5 8- 2, 82 ) 0 ,5 Im m un od éfi ci en ce 1,8 7 (1, 0 4- 3, 38 ) 0 ,0 5 0 ,5 9 (0 ,19 -1 ,9 0 ) 0 ,5 0 ,9 3 (0 ,3 8- 2, 32 ) 1 1,3 0 (0 ,4 6- 3, 64 ) 0 ,6 3, 15 (1 ,6 7- 5, 95 ) 0 ,0 0 1 N eu tr op én ie 0 ,6 2 (0 ,19 -1 ,9 6) 0 .6 1,3 3 (0 ,4 8- 3, 68 ) 0 ,5 1,8 8 (0 ,8 1- 4, 38 ) 0 ,1 4, 74 (2 ,19 -1 0 ,2 6) 0 ,0 0 1 1,8 6 (0 ,7 4- 4, 67 ) 0 ,2 So nd ag e ur in ai re 5, 59 (3 ,8 4- 8, 15 ) < 0 ,0 0 1 2, 50 ( 1,5 0 -4 ,16 ) 0 ,0 0 1 2, 63 (1 ,6 2- 4, 25 ) < 0 ,0 0 1 2, 87 (1 ,5 6- 5, 31 ) 0 ,0 0 2 3, 0 7 (1, 84 -5 ,14 ) < 0 ,0 0 1 C at hé te r p ér ip hé riq ue 1,2 0 (0 ,8 3- 1,7 5) 0 .3 4, 55 (2 ,6 7- 7,7 6) < 0 ,0 0 1 1,3 4 (0 ,8 7- 2, 0 8) 0 ,2 3, 72 (1 ,9 6- 7,0 7) < 0 ,0 0 1 3, 77 (2 ,2 1- 6, 41 ) < 0 ,0 0 1 C at hé te r c en tr al 7,8 3 (4 ,9 6- 12 ,3 7) < 0 ,0 0 1 1,6 4 (0 ,6 5- 4, 10 ) 0 ,2 5, 26 (2 ,9 5- 9, 37 ) < 0 ,0 0 1 10 ,7 6 (5 ,7 5- 20 ,11 ) < 0 ,0 0 1 3, 0 6 (1, 44 -6 ,4 8) 0 ,0 0 8 A lim en ta tio n pa re nt ér al e 1,7 2 (0 ,9 9- 2, 99 ) 0 ,0 6 3, 63 (2 ,12 -6 ,2 3) < 0 ,0 0 1 3, 42 (2 ,0 3- 5, 77 ) < 0 ,0 0 1 6, 83 (3 ,7 9- 12 ,3 4) < 0 ,0 0 1 0 ,8 8 (0 ,3 5- 2, 20 ) 1 Ve nt ila tio n m éc an iq ue 5, 5 (3 ,0 -1 0 ,1) < 0 ,0 0 1 2, 23 (0 ,8 0 -6 ,2 0 ) 0 ,12 12 ,5 4 (7 ,17 -2 1,9 4) < 0 ,0 0 1 19 ,8 2 (1 0 ,4 6- 37 ,5 6) < 0 ,0 0 1 1,8 1 ( 0 ,5 6- 5, 84 ) 0 ,2 Pr oc éd ur e ch iru rg ic al e 1,7 2 (1 ,18 -2 ,5 1) 0 ,0 0 6 - 0 ,9 2 (0 ,5 6- 1,5 1) 0 ,8 0 ,9 8 (0 ,5 2- 1,8 5) 1 1,0 3 (0 ,6 1- 1,7 5) 0 ,9 O R : o dd s r at io ; I C : in te rv al le d e co nfi an ce . طسوتلما قشرل ةيحصلا ةلجلماشرع سداسلا دلجلما شراعلا ددعلا 1077 réalisation d’actes invasifs. En revanche, et contrairement à notre étude, la pédiatrie est habituellement un service à faible taux de prévalence des infections nosocomiales ne dépassant pas 4 %, que ce soit dans les pays européens [16] ou dans les autres pays de plus faible niveau socio-économique [5,12,14]. Dans les études réalisées dans les hôpitaux sud-méditerranéens au début des années 1990, les infections du site opératoire constituaient incontestablement les infections les plus répandues, avec des fréquences relatives allant de 29 % à 39,9 % [5,11,16,17]. Dans les études les plus récentes et de la même manière que dans notre étude, les infections du site opératoire sont un peu moins fréquentes et sont dominées souvent par les infections respiratoires [12,15]. La localisation des infections nosocomiales au niveau de la peau et des tissus mous est rarement observée dans la littérature internatio- nale dans des services autres que le long séjour et la psychiatrie [4]. Par contre, cette localisation représente une part importante des infections observées dans notre étude, en Algérie et Tunisie, dans des services de médecine, chirurgie et pédiatrie. Cette prédominance a déjà été signalée dans l’étude de prévalence nationale au Maroc, et elle a été expliquée par un manque d’hygiène hospitalière englobant aussi bien l’hygiène individuelle des patients et du personnel, l’hygiène collective que le non-respect des conditions d’asepsie [5]. Dans le même ordre d’idée, les facteurs de risque extrinsèques étaient les plus associés au risque infectieux nosocomial. Une durée de séjour de huit jours ou plus augmentait considérablement le risque d’acquérir une infect ion nosocomiale . La présence d’un disposit i f invasi f ainsi que l’intervention chirurgicale é ta ient a s soc iées à un r i sque accru d’infections nosocomiales conformément aux données de la littérature [4,5,10,14,16,18]. C o n c e r n a n t l e s f a c t e u r s intrinsèques, seuls le diabète et l’âge ont été associés, de manière plus modérée, au risque infectieux. La stratification sur l’âge a révélé un taux de prévalence des infections nosocomiales particulièrement élevé chez les enfants âgés de plus d’un an. La distribution des infections nosocomiales selon les classes d’âge est assez comparable à celle retrouvée par Bezzaoucha et al. [17] où les sujets âgés de moins de 20 ans et ceux âgés de 40 à 59 ans présentaient les prévalences les plus élevées. Cette distribution est liée en partie au risque élevé dans les services de pédiatrie déjà signalé. La prescription d’antibiotiques chez les patients enquêtés était particulièrement alarmante. Cette forte prescription d’antibiotiques a été rapportée dans la majorité des études réalisées dans des pays en développement [18,19]. Ainsi 46,8 % des patients enquêtés dans un hôpital tunisien étaient sous antibiotiques et la moitié d’entre eux recevaient deux molécules ou plus ; les céphalosporines de troisième génération étaient les antibiotiques les plus fréquemment administrés [15]. À contrario, dans l’enquête nationale de prévalence de 2001 en France [4], seuls 15,9 % des patients avaient un traitement antibiotique. Cette étude a permis de faire un premier état des lieux sur la situation des infections nosocomiales dans les hôpitaux pilotes en utilisant la même méthodologie. Elle a permis de mieux approcher les spécificités locales : services de pédiatrie à risque (donc nécessité d’établir des programmes de prévention adaptés aux caractéristiques épidémiologiques de cette spécialité), forte prescription d’antibiotiques (nécessité de normes de bonnes pratiques), localisations des infections nosocomiales toutes présentes avec des proportions assez proches, écart de prévalence beaucoup plus réduit entre les services de réanimation et les autres services (notamment la pédiatrie), ce qui évoque des risques plus liés aux insuffisances dans les pratiques d’hygiène qu’aux procédures invasives. Mais pour avoir une meilleure approche de la réalité des infections nosocomia les e t pour pouvoir évaluer les tendances dans le temps, il serait intéressant que les hôpitaux participant à cette étude réalisent des enquêtes de prévalence périodiques en utilisant le même protocole d’étude.

Dans une population telle que celle de notre étude, avec une moyenne d’âge ne dépassant pas les 42 ans et une exposition aux principaux dispositifs invasifs relativement faible, le taux d ’ infect ion « incompress ible » devrait être beaucoup plus faible si un programme opérationnel en hygiène hospitalière est mis en place.

Jokhio,1 T.A. Bhatti2 and M.S. Memon3 ABSTRACT Hepatitis B and C virus (HBV/HCV) infections are serious global health problems. Shaving by barbers has been identified as the key risk factor for spread of HBV. We conducted a cross-sectional survey of barbers in Hyderabad city, Pakistan in 2007 to establish their knowledge and attitudes to the risk of HBV and HCV transmission and their working patterns. Observations showed that 96.2% washed razors with antiseptic after each client and 95.7% used a new blade with new clients. However, knowledge about the diseases and modes of transmission were poor and only 36.6% knew that hepatitis can be transmitted via shaving instruments. Only 3.2% of 186 barbers were vaccinated against HBV. Strategies are needed for raising awareness and regulations of barbers’ practices. 1Department of Community Health Sciences, Aga Khan University, Karachi, Pakistan (Correspondence to A.H.

Le rasage par les barbiers a été identifié comme étant le principal facteur de risque de propagation du virus de l’hépatite B. Nous avons effectué une étude transversale auprès des barbiers de la ville d’Hyderabad (Pakistan) en 2007 afin d’identifier leurs connaissances et leurs attitudes dans le domaine du risque de transmission des virus de l’hépatite B et C ainsi que leurs méthodes de travail. Les observations ont révélé que 96,2 % d’entre eux lavaient les rasoirs avec un antiseptique après chaque client et qu’ils étaient 95,7 % à utiliser une lame neuve pour chaque client. Mais leur connaissance de ces maladies et de leur mode de transmission était faible et seuls 36,6 % d’entre eux savaient que l’hépatite pouvait se transmettre par des instruments de rasage. Seuls 3,2 % des 186 barbiers étaient vaccinés contre le virus de l’hépatite B. Des stratégies de sensibilisation aux pratiques des barbiers et de réglementation de ces dernières sont nécessaires. EMHJ • Vol. 16 No.10 • 2010 Eastern Mediterranean Health Journal La Revue de Santé de la Méditerranée orientale 1080 Introduction Globally over 2 billion people have been infected with hepatitis B virus (HBV) [1] and an estimated 170 million people are chronically infected with hepatitis C virus (HCV) [1,2]. In Pakistan spe- cific estimates for the prevalence of both diseases range from 2%–10% [3,4]. Recently the rates of HBV infection in the country have been increasing, attributed to a lack of proper health facilities, low socioeconomic status and low public health awareness about the transmission of communicable diseases [5]. A significant proportion of those exposed to HBV become chronically infected and are at considerable risk of liver cancer, chronic active hepatitis and cirrhosis. These infected people may not be aware of their HBV status and are not clinically ill but are a source of infection to others. HBV is 50 to 100 times more infec- tious than HIV, yet is transmitted by contact with blood or body fluids of an infected person in the same way as HIV [1]. Razor shaving by barbers has been identified as a key risk factor for trans- mission of HBV [6] and HCV [7,8]. In Turkey 39.8% of barbers were found to be HBV positive and many were infected during the course of employ- ment [9]. HBV and HCV infections have been implicated as an occupa- tional hazard of the barbers’ trade in several developing countries [10–18]. In Pakistan, daily facial shaving and armpit shaving from barbers has been identified as a risk factor for transmis- sion of HBV and HCV [14–17]. Prevention is the best strategy against the epidemic of viral hepatitis. Barbers have low awareness about hepatitis and the risk of transmission of infectious agents by reuse of razors and scissors on multiple clients [19,20]. In Pakistan the prevalence of shaving by barbers is reported to be as high as 34%–49% of the male population [14] and it is im- portant to know how barbers perceive the risks in relation to prevention of transmission between themselves and customers. A very limited number of studies have been published in Pakistan investigating knowledge, attitude and practices about hepatitis transmission among barbers [19] and patients at- tending family medicine clinics [21]. We therefore designed the current study to assess the knowledge, attitudes and common practices of barbers in Hy- derabad city, Sindh province regarding risk of transmission of HBV and HCV in their work. This information will help to guide the design and implementation of appropriate prevention and interven- tions strategies. Methods This study was part of cross-sectional study conducted in Hyderabad to de- termine the prevalence and risk factors of HBV and HCV infection among barbers and their regular clients. Hy- derabad is the 4th largest city in Pakistan and 2nd largest city in Sindh province and about 200 km from Karachi, which has a mix of both low and high socio- economic residents. Sample There were 521 barbers shops registered in the city. Hyderabad city was divided into 11 zones and all the barbers’ shops were listed using the mapping exercise carried out by the Canadian Interna- tional Development Agency project for HIV/AIDS serosurveillance. Using a computer-generated, simple, random sampling procedure, 10 shops were selected from each zone to achieve the target sample size for the original cross- sectional study. From the selected 111 shops, there were 202 barbers available and eligible for interview. After giving informed verbal consent, 186 barbers agreed to participate in the study and were included in the final analysis; the refusal rate was 8% (16/202). Data collection The survey was completed during March–October 2007. Trained medi- cal interviewers visited the selected barbers’ shops and requested barbers to participate in the study. Face-to-face interviews were conducted with partici- pating barbers about their knowledge and attitudes. Before the start of the main interview, one of the accompa- nied supervisors not involved in data collection observed the barber and as- sessed his instrument use practices with clients. The questionnaire collected data about personal characteristics such as age, education, income, marital status, ethnic group and area of residence. The knowledge section covered barbers’ knowledge about different modes of transmission of hepatitis, including the risk of transmission of the disease due to use and reuse of razors, and knowl- edge of vaccines for HBV and HCV. The attitudes section covered the type of media they use for information and entertainment; attitudes towards these diseases; whether they had been vac- cinated against these diseases; whether they were a substance abuser, had had a blood transfusion, tattoos or surgical operation/stitches; and whether they thought it was necessary to have peri- odic screening for bloodborne diseases in general and whether they themselves would like to be tested for these dis- eases. The practices of barbers were ob- served on 2 occasions while they were attending clients and a checklist was used to record: hand-washing before each client; sterilization of instruments with antiseptic; use and reuse of blades; and disposal of used blades and instru- ments. A random selection of 10% of the questionnaires was checked to verify whether all questions had been under- stood by the barbers. Participation in the survey was on a voluntary basis. طسوتلما قشرل ةيحصلا ةلجلماشرع سداسلا دلجلما شراعلا ددعلا 1081 The study was approved by the ethical review committee of Liaquat University of Medical and Health Sciences. Analysis A Microsoft Access 2000 database was used for data entry and the data were tabulated and analysed by frequency distributions in SPSS, version 11.5. Results A total of 186 questionnaires were com- pleted from barbers’ interviews. The par- ticipant’s demographic characteristics are shown in Table 1. Most respond- ents (69.9%) were aged 15–30 years. Around one-third (35.5%) of barbers were illiterate and another 41.9% had education up to primary school. Nearly half (53.2%) of the respondents were unmarried. Most respondents (95.7%) were resident in the main urban areas and the largest ethnic group in terms of mother tongue was Urdu (47.8%). Knowledge Responses to the knowledge questions showed that awareness of modes of transmission of hepatitis and the different sources/risk factors were low, ranging from only 9.7% correct for foodborne transmission to 36.6% who knew that hepatitis can be transmitted through barber’s shaving instruments (Table 2). Only 11.3% of respondents knew that both HBV and HCV have the same mode of transmission and 6.5% knew that there is a vaccine that can protect against HBV, while 8.1% thought there was a vaccine for HCV. Attitudes Only 3.2% of respondents reported that they had been vaccinated against hepa- titis B virus. (Table 3) Three-quarters (74.7%) had not seen any information or radio/television programmes on these or other bloodborne diseases. Most barbers (90.3%) did not agree that it was essential to have periodic screening tests for bloodborne dis- eases in the population; however, 97.8% would themselves like to be tested for these infections: around one-quarter (24.7%) reported a history of substance abuse (Table 3). Practices Observations of barbers’ practices showed that 68.8% washed their hands before attending each client, 75.8% cleaned instruments with disinfectant between clients, 60.2% washed their instruments after shaving the clients, 72.0% washed razors with tap water before use on a new client, 96.2% also washed razors with an antiseptic solu- tion after every use, 95.7% used a new blade on new clients and 39.2% used disinfectants for skin cuts (Table 4). About one-third (34.9%) of barbers disposed of used blades in the regular garbage system. Discussion The current study has described bar- bers’ knowledge about the transmission of HBV and HCV and provides an outline for further studies. The results show low awareness about the different modes of transmission of HBV and Table 1 Socioeconomic and demographic characteristics of barbers participating in the study Characteristic No. % Age (years) 15–20 50 26.9 21–30 80 43.0 31–40 28 15.1 > 40 28 15.1 Education (no. of years) Illiterate 66 35.5 Primary (≤ 5) 78 41.9 Intermediate (≤ 12) 40 21.5 Higher/university (≥ 14) 2 1.1 Monthly income (Pakistan rupees) 2000–4000 20 10.8 > 4000–5000 71 38.1 > 5000–10 000 91 48.9 > 10 000 4 2.2 Marital status Married 87 46.8 Single 99 53.2 Mother tongue Sindhi 56 30.1 Urdu 89 47.8 Punjabi 23 12.4 Baluchi 1 0.5 Pashto 2 1.1 Saraki and others 15 8.1 Residence Urban 178 95.7 Semi-urban 1 0.5 Rural 7 3.8 EMHJ • Vol. 16 No.10 • 2010 Eastern Mediterranean Health Journal La Revue de Santé de la Méditerranée orientale 1082 HCV diseases, even though the major- ity of barbers were from the 4th largest city in Pakistan. The majority of study participants had the misconception that these diseases were not transmitted by contact with the blood of an infected person, via blood transfusion, reuse of needles or through barbers’ shaving instruments. Only 9.7%–36.6% of respondents knew about the different modes of transmission of hepatitis and the risk factors. This is similar to another study in which 13% of barbers in Rawalpindi and Islamabad urban cities in 1999 re- ported having knowledge of HBV and HCV [19]. Knowledge about specific routes of HBV transmission was also similar to the previous study. For ex- ample, 7% of barbers in Rawalpindi/ Islamabad knew that HBV could be prevented by vaccination (compared with almost the same proportion of barbers in the current study), and 13% of barbers in Rawalpindi/Islamabad were aware of the risk of transmission of hepatitis through the intravenous route (compared with 22.0% of barbers in Hyderabad). However, more of our barbers (36.6%) were aware that hepa- titis can be transmitted through barbers’ shaving instruments compared with only 12.5% in the previous study. Although mass media campaigns regarding these diseases and HBV im- munization had been introduced in Pakistan, they seem to have had a low impact concerning knowledge of HBV immunization. It may be that poor peo- ple cannot afford to avail themselves of the opportunity for vaccination and therefore are less likely to be aware about immunization. This could also be because these infections are perceived to be common diseases in Pakistan. Only 4.3% of barbers reused blades on different clients and 13.4% reused blades on the same clients for armpit shaving without antiseptic cleaning. However, is possible that they were aware of being observed during data collection and that the 65.1% of barbers who did not dispose of used blades in the bin may have been intending to reuse them later on. Clearly, reuse of blades and non-sterilization of instru- ments creates a risk of person-to-person transmission of bloodborne infection [7,14]. Blade reuse and risk of transmis- sion of diseases with similar practices have also been reported from surveys of barbers in Turkey and India [9,18]. Barbers in Pakistan and elsewhere also carry out other very risky procedures such as circumcision, incisions and wound drainage [19,20]. Our study has several important strengths, including the use of random sampling of the listed population of bar- bers in the whole city, face-to-face admin- istration of the survey questionnaire and inclusion of all the barbers working in the selected shops with a high response rate. However we also acknowledge Table 2 Barbers’ knowledge about hepatitis B and C virus diseases and their mode of transmission (n = 186) Knowledge item Yes No No. % No. % Mode of transmission Contaminated water 23 12.4 163 87.6 Food 18 9.7 168 90.3 Shared utensils 25 13.4 161 86.6 Sexual contact 67 36.0 119 64.0 Intravenous drug use 41 22.0 145 78.0 Reuse of needles 59 31.7 127 68.3 Blood transfusion 54 29.0 132 71.0 Dental procedures 38 20.4 148 79.6 Scissors/surgical instruments 46 24.7 140 75.3 Tattooing 39 21.0 147 79.0 Barbers’ shaving instruments 68 36.6 118 63.4 Ear/body piercing 39 21.0 147 79.0 Hepatitis B and C have the same mode of transmission 21 11.3 165 88.7 Protection A vaccine can protect the individual against hepatitis B infection 12 6.5 174 93.5 A vaccine can protect the individual against hepatitis C infection 15 8.1 171 91.9 Table 3 Barbers’ attitudes about hepatitis B and C virus diseases (n = 186) Attitude item Yes No No. % No. % Seen television/radio programmes on these or other bloodborne diseases 47 25.3 139 74.7 Agree with periodic screening for bloodborne diseases 18 9.7 168 90.3 Agree to be personally tested for these infections 182 97.8 4 2.2 Is vaccinated against hepatitis B 6 3.2 180 96.8 Is currently substance abuser 46 24.7 140 75.3 Has had blood transfusion 3 1.6 183 98.4 Has had tattoos 4 2.2 182 97.8 Has had surgical operation or stitching 22 11.8 164 88.2 طسوتلما قشرل ةيحصلا ةلجلماشرع سداسلا دلجلما شراعلا ددعلا 1083 diseases caused by HBV and HCV and their mode of transmission, and employed risky practices implicated in transmitting these diseases. These results raise questions about the best possible way of correcting such gaps, for example with educational and promo- tional strategies tailored to this target group. Information should be focused on the different modes of transmission and the fact that HBV is a vaccine- preventable disease whereas no vaccine is available to prevent HCV. Further studies are required to assess the effect of interventions and how to enhance awareness among this target group.

Our findings may not be applicable to barbers who have shops outside Hyderabad city. Barbers may have misunderstood questions or may not have expressed their own views. Barbers may have been aware that they were being observed, and may therefore have modified their practices. Pakistan is facing a huge burden of HBV and HCV infection. Preven- tion of transmission is the best strategy to deal with these diseases. Changing barbers’ behaviours and practices can have a direct impact on risk reduction. If alerted to the situation, barbers might even be trained to act as community HIV/hepatitis educators because of their unique access to the general male population [22,23]. Our findings demonstrate that de- spite the many mass media health edu- cational programmes regarding these diseases in Pakistan, barbers in Hydera- bad had no detailed understanding of References Table 4 Barbers’ shaving practices from observations of interactions with clients (n = 186) Practice item Yes No No. % No. % Washes hands before each client 128 68.8 58 31.2 Cleans instruments with disinfectant between clients 141 75.8 45 24.2 Washes instruments after shaving clients 112 60.2 74 39.8 Washes razor with antiseptic solution after use 179 96.2 7 3.8 Uses new blade on new client 178 95.7 8 4.3 Washes razor with tapwater before use on new client 134 72.0 52 28.0 Disinfects skin cuts 73 39.2 113 60.8 Uses same blade for armpit shaving 25 13.4 161 86.6 Disposes of used blades in the garbage 65 34.9 121 65.1 Razor cuts observed on clients 5 2.7 181 97.3 Hepatitis B.

Aljasir 1,2 and M.S. Alghamdi 3 ABSTRACT Mobile clinics have been established in Saudi Arabia to facilitate the equitable delivery of primary health care services in remote and rural areas. A descriptive cross-sectional study was conducted to investigate the perceived quality of services provided to villages in the Al-Laith region. The majority of the 176 clients interviewed were satisfied with the working hours and health staff. However, 35.8% viewed the location as unsatisfactory and 20.5% were dissatisfied with the clinic schedule. Overall satisfaction was very high, although the mobile clinics were not viewed as substitutes for primary health care centres. Public awareness of the service needs to be improved and better access and quality of services are important for optimal service provision. 1Department of Epidemiology and Community Medicine, University of Ottawa, Ottawa, Ontario, Canada (Correspondence to B.

Une étude transversale et descriptive a été réalisée afin d’étudier la perception de la qualité des services fournis aux villages de la région d’Al-Laith. La majorité des 176 personnes interrogées étaient satisfaites des horaires et du personnel de santé.

Le taux de satisfaction global était très élevé, bien que les services mobiles ne soient pas perçus comme des substituts des centres de soins de santé primaires. Il est nécessaire de mieux faire connaître cette structure au public ; l’amélioration de l’accès aux services et de la qualité de ceux-ci est importante en vue d’une prestation optimale. EMHJ • Vol. 16 No.10 • 2010 Eastern Mediterranean Health Journal La Revue de Santé de la Méditerranée orientale 1086 Introduction Saudi Arabia is a geographically varied country whose population reflects a range of social and cultural back- grounds. Primary health care services were instituted in Saudi Arabia in 1983 [1] and comprise a large network of pri- mary care centres covering most of the country [2]. Health authorities deploy continuing efforts to make these services comprehensive and capable of provid- ing high-quality preventive and curative services to citizens and residents [3–5]. There are concerns, however, about the availability of appropriate facilities to people living in remote and rural areas. While road and air transportation provides accessibility for rural patients to high-quality emergency care in hos- pitals, in many rural areas the travel time to a facility providing routine or ongoing health care services can be considerable because of difficult road conditions and a lack of adequate transport. This poses particular problems for elderly people and others such as pregnant women and children, who require medical care on a regular basis. To improve equity in the distri- bution of health care services and to reach those in high need the Ministry of Health, via the Primary Health Di- rectorate, has established a mobile clinic service. As demonstrated elsewhere, the potential clients of mobile health clinics are people living in medically underserved areas, who are likely to be poor and elderly and would otherwise not seek medical care [6]. Needs assessment is always an im- portant starting point for determining the specific needs of a population and thus for effective planning of health care services [7,8]. To be successful, our mo- bile clinic service requires evaluation and monitoring with respect to aspects such as location, types of services of- fered, staffing and the specific needs of the target population. The aim of the present study was to assess consumer satisfaction with the mobile clinics in Al-Laith region of Saudi Arabia. To the best of our knowledge, this research is the first to be conducted on mobile clinics in the Middle East and among the very few studies internationally that have provided a comprehensive evalua- tion of such services in rural areas. Methods Study setting The study was conducted in Al-Laith governorate, a remote rural area com- prising 12 administrative emirates in the south-western region of Saudi Arabia. It is divided into 2 main areas: a coastal region and a mountainous region. The total population was about 120 000 in the 1995 census. The health services in the area are provided by 25 primary health care centres and 2 small hospi- tals. Mobile health clinics in Al- Laith Two 4-wheel-drive mobile clinics were designed to provide, as much as pos- sible, the work capabilities of a standard clinic. They were intended to transport and provide working space for a doctor and a nurse (in addition to the driver) and to contain a well-equipped clinic and a laboratory capable of providing commonly needed tests. The air- conditioned mobile clinic accommo- dated a bed, drawers for the storage of instruments and bandages, and a refrig- erator for medication and vaccine stor- age. The clinic space was connected to the driver’s compartment by intercom. The van was fitted with a waste disposal tank designed for hazardous materials. Other safety considerations and the ability to withstand various climate con- ditions were also taken into account in the design of the vehicle. Among 42 underserved villages in Al-Laith area, 13 were selected for the mobile health clinics service on the basis of their remote location and complete lack of health care services. The villages were situated between 20 and 100 km from the nearest primary health care centre and each was visited 1 day per week on a regular schedule. The 2 mobile clinics were scheduled to depart from the main 2 centres located in Al-Laith area at 06:00 each day in order to provide health care services for the assigned village from 08:00–09:00 until 15:00. Research design and sample A descriptive cross-sectional research design was used to evaluate consumer satisfaction with the mobile heath clinic services. Ethical approval was obtained from the local health authorities in Al- Laith. The sample for the study was users of the mobile clinics. The 2 mobile clin- ics serve a population that has been esti- mated at approximately 17 000 on the basis of the national census conducted in 1995. A convenience sample of 200 clients—100 for each mobile clinic— was planned. To be eligible for inclusion in the study, clients were required to be 16 years or over, able to communicate and fully willing to participate. A total of 690 clients visited the mobile clinics during the research period (April 2006). The target was to select 5 or 6 clients by a simple random process at each visit. However, because of time constraints and technical problems with the mobile clinic in the mountainous region, only 197 clients were invited to participate and of these, 176 were included in the study sample from 30 visits, a response rate of 89.3%. Data collection tool A structured interview questionnaire was designed to elicit the opinions of mobile clinic consumers about the serv- ices provided and their expectations and needs. Close-ended questions were used with questions about sociodemo- graphic characteristics, general medical history and health-related behaviours, perceptions about the quality of services provided in relation to the structure of طسوتلما قشرل ةيحصلا ةلجلماشرع سداسلا دلجلما شراعلا ددعلا 1087 the mobile clinics (human resources, equipment, facilities, supplies), the process of care (system, communica- tion, quality control, policies and procedures), and the outcome of care, including patient satisfaction, as well as suggestions for improvement. The interviews were conducted by well- trained interviewers and took place in the mobile clinics during the scheduled break times. The data collection tool was pre- pared and then tested on a sample who were not subsequently included in the main study sample (n = 20). The aim of the pilot study was to test the clarity and practicality of the tools as well as their internal consistency. Among the tested questions, 21 items were constructed to have an ordinal scale to determine consumers’ satisfaction with the various aspects of the health care services. Each item was evaluated separately for its internal consistency by computing the reliability coefficient (Cronbach alpha coefficient). When any of the items showed a negative correlation, recoding of the responses was considered so that all of the items were correlated posi- tively to compute an overall reliability coefficient. Thus, the overall Cronbach alpha coefficient was 0.84, which is con- sidered high. Pilot testing also helped to estimate the time needed to conduct the inter- views and to complete the questionnaire. Minor modifications to the different data collection tools were needed. Data management For satisfaction with services, the responses “yes,” “sometimes” and “no” were scored 2, 1 and 0, respectively. The total scores for items within a question area were divided by the number of items, giving a mean score for the topic. These scores were converted into a per- centage score, and means and standard deviations (SD) were computed. The topic was considered satisfactory if the mean score was 60% or more and unsat- isfactory if the mean score was less than 60%. The cut-off point of 60% was used to facilitate comparison with previous research evaluating health care services in the area [9]. Data analysis Data entry was done using SPSS, version 11.0. Data cleaning was done and a qual- ity check was conducted for coding and data entry. Data analysis was done using the same program, in addition to the Epi-Info, version 6.04 software package. Data were presented using descriptive statistics in the form of frequencies and percentages for qualitative variables, and ranges, means and SD for quan- titative variables. Qualitative variables were compared using the chi-squared test or Fisher exact test, as appropriate. P-value < 0.05 was considered statisti- cally significant. Results Of the 13 villages included in the study, 63.1% were in coastal areas and 36.9% in mountainous areas. The characteristics of the 176 re- spondents are presented in Table 1. Participants ranged in age from 16 to 76 years, with a mean age of 37.1 years. Most (90.3%) were men. About one- third (33.3%) were illiterate, while only 2.8% were university graduates. More than half (54.0%) were married. They were mostly unemployed (72.7%). Almost all the respondents (93.2%) had used the mobile clinic service in the past. The most common sources of in- formation about the clinics were sheikhs (tribal leaders) (39.2%) and friends (35.8%). The distance from home to the clinic ranged from 0.5 km to 13.0 km. Before the mobile clinic became operational, the majority (93.2%) had received services at a primary health care centre in another village, with an average travel time of 56.8 min. However, 51.1% of respondents were still using this other service, mostly for the treatment of acute diseases in adults (48.6%). Survey responses with respect to the structure of the mobile clinics are shown in Table 2. The majority of clients were satisfied with the working hours, doc- tors and nurses, rating them acceptable or good. Meanwhile, more than one- third (35.8%) viewed the location of the clinic as unsatisfactory and 20.5% were dissatisfied with the schedule. The respondents’ rating of services provided by mobile clinic is provided in Table 3. Respondents noted the lack of many important services, or serv- ices that were not used by them, such as services for people with disabilities, laboratory tests, electrocardiography and vaccinations. Conversely, medica- tions were present in all clinics, and this aspect of care was judged as good by all respondents. Health education services were also provided in most cases and were mostly judged as good (83.5%).

EMHJ • Vol. 16 No.10 • 2010 Eastern Mediterranean Health Journal La Revue de Santé de la Méditerranée orientale 1088 The overall satisfaction of the mobile clinic users was very high; the structure of the services and the types of services provided were rated as satisfactory by 94.9% and 98.9%, respectively. There was a statistically significant difference between respondents from mountain- ous areas and those from coastal areas in their level of satisfaction with the mobile clinic structure, with more coastal resi- dents expressing satisfaction (100.0%) than those from the mountainous re- gion (91.9%) (P = 0.03). The overall opinion of mobile clinic users about the services compared with primary health care centres in other villages is shown in Table 4. Most users considered the services less satisfactory or equal to those provided in primary health care centres. About two-thirds (62.5%) viewed the mobile services as of lower quality in comparison with services provided by primary health care centres. The majority rated the services provided as good in part or in total, but 90.9% of the users did not feel that they could depend on the mobile clinics to meet all of their routine or emergency care needs. Discussion Ideally mobile clinics provide services that extend from childhood and adult immunizations, to taking medical histories and performing physical ex- aminations, providing well-child care and chronic illness management, health education and counselling, geriatric home visits and health maintenance. However, the accessibility and utili- zation of mobile health services vary greatly according to location and other characteristics, including how well the services are publicized [10]. The mobile clinics involved in the present study provide health care to underserved and difficult-to-reach areas whose underprivileged status might be inferred from the personal characteris- tics of the respondents, of whom about one-third were illiterate and more than two-thirds were unemployed. These rates are higher than the national il- literacy rate (17.1%, reported in 2005) [11] and the national unemployment rate (11.2 % and 9.8%, reported in 2006 and 2008, respectively) [12]. The low prevalence of women in our study was expected in this rural area in view of cultural barriers that discourage participation in such surveys as well as visits to health facilities by women, Table 2 Respondents’ rating of the structure of mobile clinic services (n = 176) Criterion Rating Unsatisfactory Acceptable Good No. % No. % No. % Location 63 35.8 11 6.3 102 58.0 Schedule (1/week) 36 20.5 48 27.3 92 52.3 Working hours 9 5.1 23 13.1 144 81.8 Doctors 0 0.0 2 1.1 174 98.9 Nurses 0 0.0 2 1.1 174 98.9 Table 3 Respondents’ rating of services provided by mobile clinic (n = 176) Health service Not applicable (unavailable to clients) Unsatisfactory Acceptable Good No. % No. % No. % No. % Chronic diseases 9 5.1 0 0.0 81 46.0 86 48.9 Maternity and well-baby health services 88 50.0 13 7.4 50 28.4 25 14.2 Accidents 45 25.6 18 10.2 65 36.9 48 27.3 Vaccinations 153 85.9 2 1.1 16 9.1 5 2.8 Health education 27 15.3 0 0.0 2 1.1 147 83.5 Infectious diseases 66 37.5 0 0.0 10 5.7 100 56.8 Mental health 109 61.9 8 4.5 0 0.0 59 33.5 Special needs (disabilities) 167 94.9 8 4.5 0 0.0 1 0.6 Emergency 41 23.3 0 0.0 86 48.9 49 27.8 Laboratory tests 164 93.2 0 0.0 11 6.3 1 0.6 Electrocardiography 164 93.2 0 0.0 11 6.3 1 0.6 Medications 0 0.0 0 0.0 0 0.0 176 100.0 طسوتلما قشرل ةيحصلا ةلجلماشرع سداسلا دلجلما شراعلا ددعلا 1089 except in urgent situations, and that require women to be accompanied by a male relative. Further, the fact that the clinics were run only by male workers might have discouraged their use by women, who may have travelled to a primary health care centre to receive services from female health care work- ers. Solutions to overcome this barrier and thus increase the utilization of mo- bile clinics by women could include recruiting female health care workers or extending the operating hours of mobile clinics until the later hours of the day, which would allow for the return of male relatives from work so that they could accompany female family members and children to the mobile clinic. The finding that most respondents had learned about the mobile clinics from sheikhs or friends indicates a lack of advertising about the services provided through these clinics to the local com- munity. Therefore, there is a need for more publicity on the part of health au- thorities with respect to mobile clinics. Before the mobile clinics became operational, most respondents had obtained services at a primary health care centre in another village, with an average travel time of an hour compared to a few minutes to reach the mobile clinic. About half of the mobile clinic users were still travelling to primary care centres to obtain services not provided by the mobile clinic. However, even though mobile medical programmes do not provide full services, they have the potential to improve equity in health care and disease control by providing services to high-risk individuals who may lack access to care elsewhere [13– 15]. Mobile clinics in rural areas can play a supporting role in the provision of health care services, and health care authorities can use such technology to improve access and reduce the burden of travel on patients. Mobile clinics should give emphasis to preventive as well as curative services. In this respect, Swaddiwudhipong has reported that the use of a mobile unit may be an effective means of delivering screening programmes in rural areas where existing screening activities can- not effectively reach the population at risk [16]. Respondents noted that many important services were lacking, or that some services were not relevant to them, such as services for people with disabilities, laboratory tests, electrocar- diography and vaccinations (despite the fact that the mobile clinics had been designed to provide such services). Al- though services related to disabilities might not be applicable to most visitors, the lack of services related to laboratory tests, electrocardiography and vaccina- tion do appear to constitute a weak- ness of these mobile clinics; the fact that these services were not consistently available indicates a need for improve- ment. Although health care services related to maternal and infant health were seen by 40.6% of the participants as acceptable or good, we should keep in mind the under-representation of women in the current sample, which indicates that the services utilized were likely to be related to well-baby care. Conversely, medications were avail- able in all clinics, and this aspect of care was judged as good by all respondents. Health education services were also provided in most cases, and were mostly judged as good. In this regard, current mobile clinic services should be more consistent in the services provided and should include more preventive and screening services as well. When asked their opinion about the structure of mobile clinics, most respondents expressed satisfaction with the clinic hours, doctors and nurses. However, the dissatisfaction of re- spondents with the range of services offered indicates a need for more im- provement in the services provided and for an ongoing process of determining consumer satisfaction with the services and for gathering suggestions for im- provement. There was a statistically significantly higher level of satisfaction with mobile Table 4 Respondents’ overall opinions about mobile clinic service as compared with primary health care centres (n = 176) Variable No. % Mobile clinic compared with primary centre Cannot be compared 50 28.4 Provides some services 103 58.5 Provides same services 21 11.9 Provides more services 2 1.1 Mobile clinic quality of services compared with primary centre Cannot be compared 42 23.9 Provides lower quality services 110 62.5 Provides same quality services 24 13.6 General opinion about mobile clinics Waste of money 18 10.2 Good in certain services 136 77.3 Good in all basic services 21 11.9 Good substitute for primary centre 1 0.6 Mobile clinic is dependable in providing health care in the area No 160 90.9 Yes 3 1.7 Yes, with exceptions 13 7.4 EMHJ • Vol. 16 No.10 • 2010 Eastern Mediterranean Health Journal La Revue de Santé de la Méditerranée orientale 1090 clinic services among coastal residents compared with those from mountainous areas. This may be because the residents of mountainous areas, who have no alternative services nearby, had higher expectations of the mobile clinic. Any lack of service in the mobile clinic would mean a long trip to the nearest primary health care centre for these users. In this regard, providers of health services in rural areas should give special attention to subgroups that may have different needs and require more support. In ad- dition, a quick maintenance process for the mobile clinic is required to maintain service without interruption; technical problems with the mobile clinic in the mountainous areas had an impact on the service. An alternative could be the presence of an extra mobile clinic that could replace that under maintenance, especially for areas with a challenging geographical terrain. Despite the fact that the overall satisfaction with the mobile clinic was high, most users considered the serv- ices less satisfactory than or equal to those provided in primary centres. Moreover, the majority responded that mobile clinics were not dependable in providing services in their area. Health planners and decision-makers should take these opinions into consideration. In addition, there is a need for more information for consumers about the aim of these mobile clinics and the services that should be expected from such alternative health care provision settings. Conclusion The majority of mobile clinic clients were satisfied with the services provided, although a need to provide some im- portant services more consistently and with optimum quality was noted. Issues convening access (location and operat- ing hours) should be reviewed regularly to ensure that they match the needs of the area served. It is recommended that mobile clinics be given more publicity by the health authorities, with clarifica- tion about the types of services that they provide. There is a need to improve the utilization of mobile clinic services by women. A rapid maintenance process and a continuous process of assessing the quality of services provided are needed to optimize service provision. Health planners and decision-makers should take into account the ability of mobile clinics to provide good health care in certain settings, while remembering that they cannot be relied upon as substitutes for full-service health centres.

EMHJ • Vol. 16 No.10 • 2010 Eastern Mediterranean Health Journal La Revue de Santé de la Méditerranée orientale 1092 Introduction There is a growing interest in shortening hospital stays for patients with cancer and treating them on an outpatient basis [1–3]. This shift of care from hospital to the home places considerable responsi- bility on informal family caregivers. In fact, researchers reported that caregivers assume approximately 50%–55% of the total care required for patients with cancer at home [4,5]. Caring for patients with cancer is a complex and demanding role [1,6,7]. Cancer caregivers are expected to meet patients’ needs in the physical, psycho- logical, social, spiritual and financial di- mensions [6,7]. In addition, caregivers need to balance the responsibilities of caregiving role with their own needs and demands, which is one of the most challenging problems facing caregivers of patients with cancer [1]. Previous research demonstrated that caregivers have to commence this role suddenly with limited knowledge and experiences, with a negative effect on the patient and the caregiver [1,6]. For example, in a prospective popula- tion-based cohort study, it was found that stress associated with caring for a patient with cancer increased the car- egiver’s risk of mortality by 63% within 5 years [8]. In addition, the role of caregiv- ing for patients with cancer was found to be associated with sleep disturbance [9,2], fatigue [10–12], anxiety [13], social withdrawal [4,14], depression [13,15], impaired quality of life [2] and financial constraints [2,15]. Designing individualized care plans which incor- porate caregivers’ needs is an essential element to improve the quality of care provided to patients with cancer [4,16]. In Jordan, the number of people providing care for patients with cancer at home is unknown and the needs of caregivers have never been examined before from a Jordanian Arab perspec- tive. This study was therefore designed to address the following research ques- tions: what are the health care needs identified by Jordanian caregivers of cancer patients receiving chemotherapy on an outpatient basis; how do these caregivers rank the importance of those identified needs; and are the identified needs currently being met? Methods Sample Consecutive primary caregivers accom- panying cancer patients to an outpatient chemotherapy clinic at a major univer- sity-affiliated hospital in Jordan during the period 10 August to 25 October 2006 were selected to participate in this study. Since this was an exploratory, descriptive study, no attempt was made to estimate sample size. The inclusion criteria for caregivers were: Jordanian nationality; male or female; identified by the patient as the individual who is most involved in, or affected by, the pa- tient’s situation; residing in the patient’s home; able to communicate in Arabic; and able to give written consent. Instruments Data were collected using the following scales: the caregivers’ demographic data sheet, the caregivers’ medical informa- tion form and the caregivers’ need scale. The demographic data sheet con- tained questions related to participants’ characteristics such as: age, sex, marital status, income level, number of people living in the same household and educa- tion. Two items were added to reflect structural barriers to health services: distance travelled to the hospital and usual time required to travel from home to hospital. The medical information form contained questions related to the car- egivers’ chronic medical conditions, physical disabilities and history of mental illnesses. In addition, participants were asked to report the presence of nega- tive impacts thought to be associated with the caregiving role, including sleep disturbances, fatigue, anxiety, distress, financial constraints and depression. The caregivers’ need scale was devel- oped to assess caregivers’ current health care needs in relation to the patient’s situation and contains 6 subscales and 90 items [17]. These subscales are: personal care (28 items), activity management (13 items), involvement with health care (19 items), work (2 items), inter-personal interaction (21 items) and finance (7 items). Each item is measured on a 10 cm visual scale from “not a need at all” (0) to “very big need” (10). In addition, participants are asked to indicate whether each need is being met or not. The caregivers’ need scale yields 3 scores for each item: the exist- ence of the need (an item is considered as an existing need if 66% or more of the participants report it as a need); the need was met or not met (participants mark a “need met” or “need unmet” column for each need they decide to be existing); and the importance of the need (an item is considered “very important” if 50% or more of the participants rank it as 9 or 10 on the need scale). The original author reported that the caregivers’ need scale had 99% inter-rater reliability and a reliability coefficient alpha of 0.80. Construct and face validity for the scale were also estab- lished [17]. Procedure A panel of 2 Masters level nurses and 2 lay persons who were competent in English and Arabic languages translated and back-translated the caregivers’ need scale. Any discrepancy between the original version and the translated form was resolved based on the suggestions of the researchers and the panel. Permission from the institutional review board and the hospital admin- istration was obtained before starting data collection. Then the researchers visited the clinic on a daily basis during the study period to recruit participants. Once a participant was identified the researcher approached the patient and طسوتلما قشرل ةيحصلا ةلجلماشرع سداسلا دلجلما شراعلا ددعلا 1093 caregivers to discuss the purpose and procedure of the study, invite them to participate and obtain written consent. Participants were assured that confiden- tiality would be maintained throughout the study and that the results would be reported as aggregates without revealing their identity. In addition, participants were assured that they could withdraw from the study at any time without jeop- ardizing their care at the institution. A structured interview lasting 30–35 minutes was used to collect data from each participant. Completed forms were coded and fed into a computer for data analysis. A pilot test of the translated version of the caregivers’ need scale was made with 10 participants before the beginning of the study, resulting in an alpha coefficient of 0.86. Results Participants’ demographic characteristics Of the 104 companions of patient who were approached and invited to par- ticipate, 22 (21.2%) did not meet the inclusion criteria and were excluded. Table 1 summarizes the demographic characteristics of the remaining 82 par- ticipants. The majority of participants were female (64, 78.1%) and married (58, 70.7%). The education level of participants ranged from 2 to 18 years, with a mean of 8.4 [standard deviation (SD) 12.6] years. The age of partici- pants ranged from 21 to 62 years, with a mean of 36.2 (SD 15.8) years. The distance between participants’ home and hospital ranged from 20 to 60 miles, mean 32.5 (SD 14.6) miles, and the mean time required to travel from home to hospital was 64.0 (SD 17.4) minutes. Participants’ medical status Participants reported suffering from 5 chronic medical conditions: diabe- tes mellitus (34.2%), hypertension (36.6%), angina (29.3%), renal failure (3.7%) and rheumatoid arthritis (2.4%). Negative impacts of the caregiving role experienced by participants were: fatigue (78.0%), sleep disturbance (64.6%), anxiety (60.7%), financial con- straints (58.5%) and mood disturbance (43.9%). None of the participants re- ported having major physical disabilities or a history of psychiatric illness. Participants’ existing needs Two-thirds of the participants (n = 55, 67.1%) identified a total of 68 needs, i.e. 75.6% of the 90 items found on the caregivers’ need scale. These were con- sidered to be existing needs according to the criteria identified by Longman et al. [17]. Existing needs covered all possible areas on the caregivers’ need scale, including personal care, activity management, involvement with health care, work, interpersonal interaction and finance. Participants’ very important needs A total of 46 of the 68 existing needs identified (67.7%) were considered to be “very important”. Again, very impor- tant needs covered all possible areas on the scale and the highest-rated very important needs were: to be told about symptoms that would be expected as the patient’s health changes (97.6% of participants); need for a home care or public health nurse (95.0%); need to be kept informed of patient’s condition (94.7%); help with patient’s emotional needs (87.8%); and help with additional expenses due to patient care (85.4%). Table 2 presents the very important needs identified by need area. Participants’ unmet needs A total of 52 out of 68 (76.4%) identified needs were marked as “unmet”. As with existing and very important needs, the unmet needs also covered all possible areas on the caregivers’ need scale. Ta- ble 2 presents the unmet needs reported by participants on the caregivers’ need scale by need areas. The highest rated unmet needs according to need areas were: for personal care “be assured patient • is comfortable”, “need help knowing how to care for patient” and “be told about symptoms to be expected as patient health changes”; for activity management: “help as-• sessing his/her ability to give his/her own care (e.g. taking medication or changing a dressing), “help with ways Table 1 Demographic characteristics of participants (n = 82) Characteristic No. % Sex Male 18 22.0 Female 64 78.1 Marital status Married 60 73.2 Single 14 17.1 Widow 5 6.1 Divorced 3 3.7 Mean (SD) Range Age (years) 36.2 (15.8) 21–62 Education (years) 8.4 (12.6) 2–18 Travel distance to hospital (miles) 32.5 (14.6) 20–60 Time to travel to hospital (min) 64.0 (17.4) 35–120 Income (US$) 380.8 (150.6) 100–1800 No. of people in household 6.6 (4.5) 0–12 SD = standard deviation EMHJ • Vol. 16 No.10 • 2010 Eastern Mediterranean Health Journal La Revue de Santé de la Méditerranée orientale 1094 of relieving the patient’s physical dis- tress”, “need information about com- munity resources to help with his/ her activities of daily living (meals, housekeeping, etc.); for involvement with health care: • “need to be informed of any changes”, “need to be kept informed of patient’s condition”, “need to be closer to the medical centre”; for work: “need to balance homemak-• ing with patient’s needs”; for interpersonal interaction: “need • to share feelings and experiences with others in similar situations”, “need for acceptance, support, and comfort from staff”, “need to express my own emotions”; and for financial: “need to obtain financial • assistance for patient”. Table 3 shows the items on the car- egivers’ need scale identified as very im- portant needs by need area; the highest rate very important needs are marked. Discussion Jordanian caregivers of patients with cancer in this study reported almost double the number of existing needs identified by caregivers in 2 studies in the United States of America (USA) [17,18]. Table 4 compares the results of Longman et al. [17] and Silveira and Winstead-Fry [18] with the current results. Very important needs of the urban and rural samples in the USA were identified in only 3 areas (per- sonal care, involvement with health care and interpersonal interaction), while Jordanian caregivers reported very important needs in all 6 areas of the caregivers’ need scale (personal care, activity management, involvement with health care, work, interpersonal interac- tion and finance). About 76.5% of the existing needs identified were found to be unmet among Jordanian caregiv- ers, as compared with 30% and 14% for the urban and rural USA samples respectively. These results suggest that there is insufficient attention given to the needs of caregivers of patients with cancer in Jordan. The differences in the results can be attributed to several factors. First, there were demographic differences between the 3 samples. For example, the Jordanian participants were younger, less educated, travelled longer and spent more time travelling to hospital than the USA urban and rural samples. Secondly, there are unique features of the Jordanian health care system. These features include problems with access to care (physical distribution and insurance), inadequate staff and sup- plies and poor availability of supportive services. Primary and secondary health services are available and accessible to most Jordanians [19]. However, tertiary and specialized services are centralized in major cities, oncology services are limited to 2 major cites, and radio- therapy is available only in the capital, Amman. On average, participants in this study reported that they travelled 60 miles and spend 90 minutes to obtain their required services. Such a problem places extra burdens of cost and effort on patients and their caregivers, which limits their ability to seek help when they need it. Although about 32% of Jordanians have no health insurance [19], unin- sured oncology patients can obtain medical treatment in public institutions free of charge. Therefore, health insur- ance appears not to be a problem for such patients. Although Jordanian hos- pitals employ the highest available tech- nologies and very competent physicians and nurses, there are staff shortages, high number of patients being treated in outpatient chemotherapy clinics and brief contact times between health pro- fessionals and patients. These factors limit the supportive and educational services provided to the caregivers of patients. Researchers reported that Jorda- nian hospitals are experiencing falling values of salaries, shortages of drugs and supplies, shortages of physicians and nurses and high bed occupancy rates (80%) [20]. The majority of Jordanian hospitals do not employ support serv- ices such as psychologists and social workers. Researchers assert that Arabs are not familiar with the profession of Table 2 Items identified as existing, very important and unmet needs by caregivers of cancer patients Need area Total items Existing needsa Very important needsb Unmet existing needs No. No. %c No. %d No. %d Personal care 28 22 78.6 13 59.1 18 81.8 Activity management 13 11 84.6 8 72.7 11 100.0 Involvement with health care 19 13 68.4 11 84.6 9 69.2 Work 2 2 100.0 1 50.0 2 100.0 Interpersonal interaction 21 15 71.4 11 73.3 10 66.7 Finance 7 5 71.4 2 40.0 2 40.0 aExisting needs were items identified by more than 66% of participants as needs. bVery important needs were those rated by more than 50% of participants as 9 or 10 on a scale of 0–10, with 10 the highest. cPercentage of total. dPercentage of existing needs. طسوتلما قشرل ةيحصلا ةلجلماشرع سداسلا دلجلما شراعلا ددعلا 1095 social work, and rely on family mem- bers and friends for help and support [21]. In addition, Arabs perceive mental and emotional illnesses as stigmatizing, which limits the use of psychologists in Jordanian hospitals [21,22]. Furthermore, home nursing serv- ices, help groups and agencies, and Table 3 Items identified as very important needsa by caregivers of cancer patients Personal care Be assured patient is comfortable Need help with patient’s emotional needs Need help knowing how to care for patient Need help with patient’s pain management (i.e. medications, other) Knowing how to observe the effects of treatments ordered by physician Be taught about the medication the patient takes at homeb Discuss the person’s illness and the nursing care needed Getting relief for anxiety by having reasons for the person’s symptoms explained Help using safe technique when giving care Discuss how changes in health status affect his/her daily living activities (e.g. ability to dress or bath self, go shopping or use phone) Be told about symptoms to be expected as the patient’s health changesb Be assured that I am providing good careb Discuss psychological management Activity management Opportunity to discuss ways to adapt his/her health status changes Help assessing his/her ability to give his/her own care (e.g. taking medication or changing a dressing) Help with ways of relieving the patient’s physical distressb Chance to talk about ways of modifying the environment to make it easier for him/ her to change Need information about community resources to help with his/her activities of daily living (meals, housekeeping, etc.) Take time to talk with me and answer my questionsb Chance to discuss alternatives for providing careb Help with transportation Involvement with health care Help available with emergency measures, if needed Need for a home care or public health nurse Need to be informed of any changesb Need to be kept informed of patient’s conditionb Need to be closer to the medical centreb Help conveying patient’s or my concerns Chance to discuss situation with other health professional(s) Access to prescription medication Obtaining needed equipment Need for more information about home care Need for help in emergency situations Work Need to balance homemaking with patient’s needsb Interpersonal interaction Need to share feelings and experiences with others in similar situations Need for acceptance, support, and comfort from staffb Need to express my own emotions Need to have the feeling of not being rushedb Need someone to listen to meb Need to have someone enquire about my health Financial Need to obtain financial assistance for patientb Need help with additional expenses due to patient care aVery important needs were those rated by more than 50% of participants as 9 or 10 on a scale 0–10, with 10 being the highest. bHighest rated very important needs. educational materials are very scarce in Jordan, resulting in limited resources when Jordanian caregivers need help and support. Moreover, the fact that caregivers’ needs are not incorporated in the nursing care plans further com- plicates the problem, resulting in car- egivers’ needs being unexplored and unmanaged. Finally, cultural issues of Jorda- nian Arabs may explain the increased number of existing and unmet needs reported by participants in this study. These issues are the high sense of obli- gation and commitment to the ill, the gaps in communication patterns and the utilization of ineffective traditional treatments. Jordanians, as Muslims, feel they should be very committed to the care of the sick and weak; care for the elderly and sick is regarded as an expres- sion of worship [21,23]. This sense of commitment is expressed at 3 levels: intentions (promises and pledges a per- son retains deep inside about a specific situation), verbal expressions (words a person uses about the situation) and actions (measures the person takes to implement the intentions) [23]. Con- sequently, Muslims attempt to reach a state of perfection in their care for loved ones who are sick, which may exacerbate the sense of burden, especially when the care is complicated, such as in the care of cancer patients. As for communication patterns, caregivers of Jordanian patients with cancer may not report their distress to health care professionals for 3 rea- sons. First, Jordanian caregivers may not express their sense of distress and burden to avoid being perceived by the patients as if they are trying to quit. Secondly, Muslims are encouraged to meet hardships, illness and death with patience and prayer, and to avoid exces- sive complaints. Thirdly, Arabs regard revealing family issues to strangers as a sign of mistrust and weakness [22]. Fourthly, when a treatment plan is not suited to an Arab client, it will result in noncompliance with the instructions EMHJ • Vol. 16 No.10 • 2010 Eastern Mediterranean Health Journal La Revue de Santé de la Méditerranée orientale 1096 References Glajchen M.

Other authors assert that Arab patients seek medications from pharmacists without prescriptions and become disappointed if they are not treated with a variety of medications for the same illness [21]. Finally, Arab clients prefer more ag- gressive treatments over teaching and counselling. For example, they prefer injections to tablets, and intravenous to intramuscular treatments [24].

USA = United States of America. There were some limitations to the current study. It utilized a small non- representative sample, which limits the generalizability of the results. Although the caregivers’ need scale has been demonstrated to be applicable to other cultures, it may lack cultural sensitiv- ity to capture the unique features of the Jordan Arab culture. In spite of the limitations of this study we can recommend that caregivers in Jordan would benefit from measures to satisfy their unmet needs, including the establishment of a home health care nursing system; facilitation of travel from their home to hospitals; written teaching materials to help patients and caregivers understand the disease proc- ess, treatment options and self-care strategies; and the establishment of formal and informal community sup- port systems. طسوتلما قشرل ةيحصلا ةلجلماشرع سداسلا دلجلما شراعلا ددعلا 1097 Ahmad NM. 21.

Women’s health A number of advances have been made over the past few years in respect to women’s health issues, and in fact, such issues are more openly discussed nowadays and women themselves are more involved in controlling their own health. Although there is still no room for complacency, there has been significant progress in opportunities for health education and treatment, including preventive treatment. In her inaugural speech to the World Health Assembly in 2006, Margaret Chan, Director General of the World Health Organization, spoke at length on this topic: “The health of women must be the other key indicator – and I do not mean just maternal health. Women do much more than have babies. Unfortunately, their activities in households and communities, coupled with their low status, make them especially vulnerable to health problems – from indoor air pollution and multiple infectious diseases to violence. Yet evidence from many sources also shows that women are agents of change – for families, the workforce, and entire communities. The health of children largely depends on the health of women. As mothers, as sisters, as aunts and as grandmothers in the home. As carers, as teachers and as health workers in the community. And I have been all of these - except a grandmother! Reducing health problems in women and empowering them will result in a dramatic increase in health-promoting behaviours – right where it counts most.” (Source: http://www.who.int/dg/speeches/2006/wha/en/index.html) EMHJ • Vol. 16 No.10 • 2010 Eastern Mediterranean Health Journal La Revue de Santé de la Méditerranée orientale 1098 Review Demographic transition and potential for development: the case of Iraqi Kurdistan T.S. Al-Hadithi,1 N.P. Shabila,1 N.G. Al-Tawil 1 and S.M. Othman1 ABSTRACT The effect of population growth and demographic transition on economic development has been well documented. The population growth in Iraqi Kurdistan is passing through a critical stage of demographic transition. It is, in fact, extremely likely that the region will fail to efficiently move through the demographic transition and will experience a long period in the demographic trap, i.e. the population will grow steadily and rapidly owing to the high fertility and low mortality rates. With correct government policies in terms of promoting family planning programmes, should the political context allow, demographic transition can pass smoothly through this critical stage. Furthermore, if demographic transition in Kurdistan moves to the next stage, it will provide an important window of opportunity for economic development. Proper exploitation of this demographic window through investment in education, on-the-job training and health services, in addition to proper and appropriate exploitation of economic resources and suitable and productive use of the labour force, will result in significant economic development over the next few decades. 1Department of Community Medicine, College of Medicine, Hawler Medical University, Erbil, Iraq (Correspondence to N.P.

La croissance démographique au Kurdistan irakien est entrée dans une phase cruciale. En réalité, il est fort probable que la région ne traversera pas aisément la transition démographique et connaîtra une longue période de « piège démographique » : la population augmentera régulièrement et rapidement en raison d’un taux de fécondité élevé et d’un faible taux de mortalité. Avec une politique gouvernementale appropriée promouvant des programmes de planification familiale - si le contexte politique le permet, la transition démographique pourrait traverser sans heurts cette phase cruciale. En outre, si celle-ci passe au stade suivant, elle constituera une période très propice au développement économique. La mise à profit de cette opportunité démographique par l’investissement dans l’éducation, la formation en cours d’emploi et les services de santé entraînera un développement économique important dans les prochaines décennies, si elle est associée à une exploitation appropriée des ressources économiques et à une utilisation adaptée et productive de la population active. طسوتلما قشرل ةيحصلا ةلجلماشرع سداسلا دلجلما شراعلا ددعلا 1099 Introduction The implication of population growth on economic development has been an issue of long-standing debate [1]. A number of studies have tackled this issue, leading to the emergence of many views and theories that have varied enor- mously over time. Generally speaking, there have been 3 positions regarding such implications: one optimistic, one neutral and the other pessimistic [2,3]. The pessimists considered rapid popu- lation growth an obstacle to economic development and a trap for the poor countries where all efforts will go to addressing the needs of the larger popu- lation while maintaining them under poorer and deteriorating conditions. The proponents of the neutral posi- tion denied any significant implications of population growth and attributed poverty to other factors such as govern- ment policies and institutional defects. The optimists went even further to em- phasise the importance of population growth as a stimulant for technological progress and economic development [1]. Population growth came onto the agenda only around the 18th century. Prior to this, the high fertility required mainly for supporting agricultural ac- tivities was counterbalanced by the high mortality. The high mortality was due to the effects of low level of health and socioeconomic conditions, including famines, unsanitary living conditions, disease, and general poverty [4]. The high population growth rates noticed in the 20th century were a result of the substantial decline in mortality and the continued high and sustained fertility, in particular in the developing countries [5]. The current total fertility rate is around 1.4 in Europe, 2.4 in Asia and Latin America and 5.0 in Sub-Saharan Africa [6]. Even though the total fertility rate in Iraq significantly decreased from 7.2 in 1970 to 5.9 in 1990 and to 4.07 in 2007, the rate is still very high [7]. The Iraqi Kurdistan region had the same total fertility rate (4.07) in 2007; this is projected to be 3.32 in 2015, which is still high [7,8]. In 2005 the global population was around 6.6 billion and is projected to be 9 billion in 2050; ranging from 7.7 to 10.6 billion depending on future fer- tility [7]. Currently rapid population growth at rates above 2% is common in most developing countries, especially in Africa [5]. In Iraq, the annual popula- tion growth rate of 3% in the 1990s has decreased to 2.62% in 2007, which is still in the rapid growth category. This is projected to continue at a high level even in 2015, with an estimated rate of 2.18% [7]. The present annual population growth in Iraqi Kurdistan is estimated at 2.75%, and a high rate is projected to continue till 2015 [7,8]. This review discusses the different views and theories on the implications of rapid population growth on eco- nomic development. It also attempts to examine the experience of a number of regions of the world regarding the im- pact of population growth on economic development. More specifically, it puts greater emphasis on the situation in Iraqi Kurdistan and tries to give an un- derstanding of the trend in this region through analysing the existing data and information and comparing it with the experience of other regions. The specific population charac- teristics or figures for Iraqi Kurdistan, wherever available, have been used throughout this review, whereas the population estimates and projections for Iraq as a whole have been used in cases where specific data for Iraqi Kurdistan were unavailable. Review Population debate Thomas Malthus, in his famous “First Essay on Population” in 1798, argued that population would grow more quickly than food production and went on to strongly suggest that rapid population growth hinders economic development [2,9]. The experience of the next 2 centuries revealed that Malthus’ pre- dictions were not sustained as people consciously managed fertility due to changing conditions. Furthermore, food production expanded as a result of advances in technology [1]. Another famous contribution to the population debate came from Ester Boserup, who argued that population growth increases settlement densities and creates pressure on resources and thus stimulates innovation and improve- ment in agricultural technology [10]. Recent studies put more emphasis on the impact on economic develop- ment of factors other than population growth alone. These studies stressed the importance of factors like family plan- ning, age structure, and government policies and investment in determining economic development [2]. Demographic transition Demographic transition is a 4-stage model that describes population change when a country moves from high to low fertility and mortality rates as part of economic development [11]. Stage 1 is associated with pre- development time and is characterised by high but approximately balanced fer- tility and mortality rates. Consequently, this stage results only in very slow popu- lation growth [10]. In stage 2, the mortality rate declines as a result of significant improvements in public health and food supply. The fertility rate, however, remains high or even increases slightly. Stage 2 is charac- terised by increasingly rapid population growth. Subsequently, the proportion of children will be very high and as a result the proportion of consumers will be higher than that of producers. At this stage, the country needs to invest well in the children through quality education and training in order to prepare a highly qualified labour force that can give a boost to the economy in the future [11]. EMHJ • Vol. 16 No.10 • 2010 Eastern Mediterranean Health Journal La Revue de Santé de la Méditerranée orientale 1100 In stage 3, substantial decline in fertility rates moves the population to- wards stability. This decline is mainly related to increased urbanization, better education and employment among women and availability of family planning programmes. As a result, the proportion of children starts to decline while the proportion of working age people starts to rise. Stage 3 has a par- ticular period, called the “demographic window”, which starts about 15 years after the decline in fertility and lasts for around 30–40 years. The demographic window constitutes an economic bonus which can result in an economic boom if the country properly absorbs and productively employs the extra labour force [10]. Stage 4 is characterised by popula- tion stability and an increased propor- tion of elderly in the age structure, and thus increased dependency. In cases where the fertility rate declines below replacement level, the population may even start to decline. This period can again have a negative impact on eco- nomic growth if not tackled in policy [10,11]. When a country fails to efficiently move through the demographic transi- tion, the population constantly grows extremely rapidly due to high fertility and low mortality rates. Here the coun- try ends up spending a big share of its resources to provide public services to the increasing population and will be stuck in what is called the “demographic trap” [10,11]. Experience of different regions Different regions of the world have different experiences in terms of ac- commodating population growth and applying policies to cope with the de- mographic transition. East Asia entered the demographic transition very early and moved through it very rapidly. The decline in fertility rate was the effect of successful family plan- ning programmes through encouraging contraception and providing incentives for decreasing birth rates. The govern- ments were successful in tackling the baby boom through the provision of high quality education and training es- pecially by expanding secondary educa- tion, which resulted in the production of a high quality labour force [10]. Furthermore, the policies of East Asia governments in encouraging investment and trading, investment in agriculture and industry as well as proper use of resources resulted in providing employment to the newly emerged labour force. These policies had enormous effects on reducing in- come inequalities. The increased job opportunities for women and decline in fertility rate have resulted in more women engaged in productivity, and thus further increased the proportion of producers. As a result, the region was very successful in exploiting the demo- graphic bonus and experienced high economic growth rates, the so called “economic miracle”. However, over the next 1–2 decades, the dependency ratio may increase again in the region due to the effect of a growing proportion of elderly people, which may negatively affect the economic situation [12]. Latin America followed a similar population pattern as East Asia. The region experienced a dramatic fall in mortality rates followed by a decline in fertility rates. However, the region was not able to experience economic growth similar to that of eastern Asia. Actually, Latin America failed in prop- erly exploiting the demographic bonus as a result of poor government poli- cies, improper investment in building high quality labour forces, improper use of resources and lack of investment in trade [1]. In Sub-Saharan Africa the decrease in mortality rate was not followed by a decline in fertility rate. As a result the population continued to grow. In 1990, around 45% of people in sub- Saharan Africa were living in extreme poverty. While this proportion only slightly increased by 2001, this meant an additional 87 million people in poverty due to the effect of population growth. The rapid population growth in the re- gion is an important obstacle to tackling poverty and apparently all efforts could not even keep the numbers of people living in extreme poverty stable [13]. While many countries in Sub- Saharan Africa are stuck in a demo- graphic trap, there is no good evidence that countries that are moving through the demographic transition will be able to benefit from the demographic bonus. With the existing government policies and investments, it is quite unlikely that countries in Sub-Saharan Africa can fol- low the East Asia model. However, there is still time for these countries to adopt strategies to exploit such opportunities and promote economic growth [10]. The case of Iraqi Kurdistan According to the 2007 population estimates and population projection, Iraqi Kurdistan is at the end of stage 2 of demographic transition and will enter stage 3 over the next few years. This can be concluded from the high total fertility rate of 4.07 and the current population age structure. According to the 2007 age structure, a very high percentage of people are in the age group 0–14 years (39.45%), i.e. dependants. On the other hand, the workforce age group (15–64 years) has experienced little expansion (57.57%) [7,8]. According to population projections, Iraq, including the Kurdistan region, will continue to have a high proportion of dependants (36.3%) in 2015 [7]. This association suggests that Iraqi Kurdistan is going to experience a long period in the demo- graphic trap. There are no systematic, efficient family planning programmes in Iraqi Kurdistan even though the fertility rate is very high. While there are some programmes existing, they are actually inefficient, and do not sustain wide cov- erage or effective provision of consul- tancy or distribution of contraceptive pills and condoms. The unmet need for طسوتلما قشرل ةيحصلا ةلجلماشرع سداسلا دلجلما شراعلا ددعلا 1101 contraception among Kurdish women is considerably high (29.3%) leading to high unwanted fertility [14]. In fact, the government is still working with the sys- tems and rules that were adopted in the 1980s to encourage fertility during the Iraq–Iran war, such as long maternity leave and incentives for children [15]. In terms of the related economic situation, the Iraqi economy is domi- nated by oil. In addition to having a high unemployment rate, ranging from 30% to 60%, more than 66% of the labour force in Iraq work in service provision sectors rather than production sectors [16]. In the Kurdistan region, agriculture and tourism can contribute effectively to economic development. Kurdistan, in fact, has experienced an important advance in foreign and internal invest- ment in many sectors during the last few years, but mainly in the oil sector [17]. Education is free in Iraq and there is extra support and a lot of incentives in Kurdistan towards encouraging educa- tion at all stages of study. Even though the education system is below interna- tional standards, the region has expe- rienced some changes and advances in the system over the last few years. However, the country is facing serious challenges in terms of accommodat- ing the growing generation in schools and universities. Furthermore, most of those who complete their studies end up working in public service sectors, i.e. they become dependent rather than productive. With the current trend of high fer- tility rate and high population growth, Iraqi Kurdistan will most probably fol- low the African model. However, the level of poverty will not be as bad as in Sub-Saharan Africa owing to the oil- dominated economy. If the fertility rate constantly decreased and proper invest- ment was made in education and training with good economic investment, Iraqi Kurdistan would follow the East Asia model of economic boom. Otherwise, it will follow the Latin America model of no significant economic growth. Discussion Many countries have managed to ac- commodate population growth to some extent and have been able to increase the average income in spite of popu- lation growth. Moderate population growth can be beneficial in particular situations. When economic growth is accompanied by moderate population growth, it can stimulate demand and encourage technological innovation and investment. Similarly, moderate labour force growth, combined with sufficient resources, good governance and investment policies and increased spending on education, can lead to eco- nomic development [4]. Meanwhile, it is also well document- ed that rapid population growth can slow development in developing coun- tries, especially when they already suffer from the effects of poverty and food insecurity. Similarly, high fertility can reduce the amount of time and money spent on children’s development at the family level. It is also true that poor people who have large families ben- efit less from public services like health and education when these cannot keep pace with population growth. Rapid population growth can also weaken government potential and exhaust its resources, making it much more difficult to invest in education and infrastructure to ensure economic development. However, studying the implications of population growth on economic de- velopment without considering other factors such as fertility and mortality patterns, age structure of the population, and government policies would be neither informative nor useful [9]. Ex- amination of the context of population changes and the effect of demography on development should take into con- sideration studying population along- side the effect of other determinants of economic development. The effect of population growth may vary widely, de- pending on the institutional, economic, cultural and demographic setting [2]. Determinants related to quality of population, age structure, political sta- bility, government policies regarding family planning, investment in popula- tion and in economic means, as well as using the demographic transition op- portunities are more important factors that influence economic development than merely population growth [18]. Promotion of family planning when the birth rate is high, as in Iraqi Kurdis- tan, is essential to pass through the demographic transition successfully. In addition to its direct role in reducing poverty, family planning will decrease maternal and childhood deaths, leading to women’s empowerment and well- being, and contribute to the provision of better quality of services such as health and education. Provision of compre- hensive, accessible and modern family planning services will eventually lead to more opportunities for women to work and thus contribute to increasing the proportion of producers and also sup- port better rearing of children [6,14]. However, adoption of strict family planning policies in the current political context in Iraq is not easy and there are many challenges due to the association of ethnic, sectarian and territorial rights with population size. The investment of the Kurdistan Regional Government in health and education of children and youth, espe- cially during this critical period of baby boom and demographic transition, is crucial to obtain a high quality popula- tion with a specialized and strong labour force that will be an asset for economic development during the demographic window phase, especially since the region is already experiencing some trends of economic development. Proper exploitation of the demo- graphic bonus opportunity in the Kurdistan region will ensure effective economic development as such an op- portunity occurs only once, and may not recur. Adoption of policies for strengthening the land, labour, industry, trade and markets as well as providing EMHJ • Vol. 16 No.10 • 2010 Eastern Mediterranean Health Journal La Revue de Santé de la Méditerranée orientale 1102 openings for trade, foreign investment and the creation of job opportunities at this demographic stage will enforce economic development [1]. Conclusion Demographic transition is in a criti- cal stage in Iraqi Kurdistan and there is a clear need for action in terms of adopting appropriate family planning policies in order to go through the tran- sition smoothly. As the demographic window will appear shortly after this transition is passed through, the Kurdistan govern- ment needs to strengthen the policies it has already initiated for better and more effective education, on-the-job training and health services, as well as proper investment and exploitation of important resources like oil, agricul- ture and tourism. However, the current political and demographic contexts of Kurdistan and Iraq as a whole hinder the adoption of large-scale, strict family planning policies.

Karimi: abbasalikarimi2006@yahoo.com). Received: 14/02/09; accepted: 22/03/09 Introduction As previous studies have revealed, postoperative chylothorax is a rare complication of cardiothoracic surgery procedures, especially myocardial revascularization [1–4]. It occurs in less than 1% of thoracic procedures [5] and 0.6%–0.8% of cases of cardiovascular surgery [6]. We describe a case of chylothorax that occurred a few days after coronary artery bypass grafting and which was treated only with low-fat diet. Case presentation A 54-year-old diabetic man underwent triple coronary artery bypass grafting using the left internal mammary artery (LIMA) and saphenous vein. The LIMA was harvested with electrocau- tery and grafted onto the left anterior descending artery. The first postopera- tive day was uneventful, but the second was complicated by severe left-sided chylothorax. The chest tube drainage contained about 400 mL of a milky fluid with a biological analysis of 88 mg/dL cholesterol and 250 mg/dL triglycerides. All the pleural effusion cultures and smears for Mycobacterium spp. were negative. A diagnosis of chylothorax was made due to lymphatic injury during LIMA harvesting, and the patient was placed on a low-fat diet. The chylous effusion gradually reduced over the following 21 days (total 3480 mL) using this conservative management. The amount of discharge on each day is shown in Table 1. The chest X-ray was normal with no localized plural effusion or opacifica- tion. The patient was discharged on postoperative day 27, and remained well at 60 days’ follow-up. Discussion Postoperative chylothorax, albeit rare, is a serious complication with a high mortality rate, which can approach 50% in untreated patients [4]. Furthermore, it can lead to fluid and electrolyte distur- bances, protein–calorie malnutrition, coagulopathy and increased susceptibil- ity to infection [7]. The lymphatics of the internal tho- racic chain and left anterior mediastinal lymph node chain (LAMLNC) are divided during internal thoracic artery dissection in coronary artery bypass grafting. The LAMLNC is an important pathway for left lung lymph drainage [2]. It normally connects with the left jugulo-subclavian venous confluent after having crossed the LIMA near its origin at the apex of the thorax and sometimes with the arch of the thoracic duct near its termination [8]. Lymph vessels have valves and normally back-flow is im- possible. Chyle valve insufficiency may allow backflow from the thoracic duct within the LAMLNC. Injury of such a backflowing LAMLNC is more likely to explain chylothorax as a complication of LIMA harvesting than the injury of the thoracic duct itself since this is more deeply located in this region. The rarity of chylothorax following LIMA harvest is explained by the usual lymph vessel valve competency of the LAMLNC, Table 1 Amount of discharge in a patient with chylothorax after coronary artery bypass and internal mammary artery harvesting Days post-operation Amount of discharge (mL) 2 400 3 300 4 350 5 250 6 210 7 200 8 300 9 150 10 50 11 230 12 250 13 300 14 210 15 0 16 100 17 50 18 70 19 150 20 10 21 50 22 0 23 0 Total 3480 EMHJ • Vol. 16 No. 10 • 2010 Eastern Mediterranean Health Journal La Revue de Santé de la Méditerranée orientale 1104 Choong CK, Martinez C, Barner HB.

References which is not always connected with the thoracic duct itself [2]. Chylothorax is mainly treated by diet modification, including a low-fat diet or a diet with medium-chain triglycerides. In some cases, chylothorax is treated by somatostatin, and operative treatment remains an option for resistant chylot- horax with no response to conservative medical treatment [1]. Late presenting chylothorax responds more readily to conservative treatment as the leak vol- ume is smaller and healing is more likely [3]. As Choong et al. showed in their literature review, most cases with early presenting chylothorax respond only to surgical procedures [1]. Our case and that reported by Weber et al. in 1981 [9] do not agree with the above findings. On the second postoperative day, our patient developed severe chylothorax, which lasted for 21 days. However, he had no further complications related to chylothorax and responded well to dietary modification. In conclusion, conservative therapy in uncomplicated cases of chylothorax seems to be a favourable option, and surgical intervention should remain as a final choice if conservative therapy fails. طسوتلما قشرل ةيلماعلا ةحصلا ةمظنلم ةيميلقلإا ةنجللا ءاضعأ نادلبلا ةيملاسلإا ناريإ ةيروهجم . ةيبيللا ةيبرعلا ةييرهمالجا . سنوت . نيرحبلا . ناتسكاب . ةدحتلما ةيبرعلا تاراملإا . ناتسناغفأ . ندرلأا صرم . نانبل . تيوكلا . رطق . ينطسلف . نماُع . قارعلا . لاموصلا . نادوسلا . تيوبيج . ةينميلا ةيروهملجا . ةيروسلا ةيبرعلا ةيروهملجا ةيدوعسلا ةيبرعلا ةكلملما . برغلما Subscriptions and Distribution Enquiries regarding subscriptions and distribution of the print edition of EMHJ should be addressed to: Printing and Marketing of Publications at: email: pam@emro.who.int; tel: (+202) 2276 5000; fax: (+202) 2670 2492 or 2670 2494 Permissions Requests for permission to reproduce or translate articles, whether for sale or non-commercial distribution should be addressed to EMHJ at: emhj@emro.who.int Members of the WHO Regional Committee for the Eastern Mediterranean Afghanistan .
