Abstract

Background: Directly observed therapy-short course (DOTS) had been adopted by World Health Organization (WHO) as hopeful strategy for treatment of tuberculosis (TB) since early nineties. Iraqi health authorities started DOTS implementation since 2001 in Baghdad. Coverage expanded gradually till 100% in 2004. War and unstable security condition hit Iraq since March 2003. Objective: The objective of this study was To evaluate the DOTS implementation program in Baghdad in different periods including 2 unstable periods for proper assessment of war and instability on treatment of TB. Patients and methods: This study had been conducted in Baghdad during four different periods (before and during 2003 war, after war; without and with DOTS). Direct interview with patients, and follow up of their treatment were done. Results: The results reveled that78% of patients were in active age groups, 62% of them were males. Surprisingly, direct observation was not achieved in those who were treated under DOTS in the whole periods. Patients treated under DOTS in the 1st and 4th periods showed much better sputum conversion rate after 2 month treatment (88.7 %in 1st and86.5% in 4th periods` patients) than those treated under DOTS during war (45.9% or Non-DOTS 75.6%). A better cure rate also found in patients of both periods (64.9% in 1st and 63% in 4th period) than patients in other periods ( 11% in 2nd% and 43.6% in the 3rd one) .Conclusions: DOTS strategy played important role in improving registration and curing of TB cases in Baghdad. War and unstable security conditions got a destructive effect on treatment of TB patients regardless the followed strategy. Involvement of private medical sector and other governmental and nongovernmental organization can improve TB treatment outcome.

Abstract

Monthly rainfall data of Baghdad meteorological station were taken to study the time behavior of these data series. Significant fluctuation,very slight increasing trend and significant seasonality were noticed. Several ARIMA models were tested and the best one were checked for the adequacy. It is found that the SEASONAL ARIMA model of the orders SARIMA(2,1,3)x(0,1,1) is the best model where the residual of this model exhibits white noise property, uncorrelateness and they are normally distributed. According to this model, rainfall forecast for four years was also achieved and showing similar trend and extent of the original data.

استخدمت البيانات الشهرية للامطار في محطة بغداد للأنواء الجوية لدراسة السلوكية الزمنية لها حيث تم ملاحظة تذبذبات واضحة فيها مع وجود نمط تزايدي طفيف جدا اضافة الى الدورية الواضحة فيها. تم اختبار نماذج متعددة لل ARIMA واخضاع النموذج الافضل لاختبار الوائمة. لوحظ ان افضل نموذج كان ذا المعالم SARIMA(2,1,3)x(0,1,1) اذ تعكس بواقي هذا النموذج خصائص سلسلة الضجة البيضاء. تم استخدام هذا النموذج للتنبؤ بقيم الامطار لفترة اربع سنوات قادمة بعد التحقق من موائمته لتمثيل المعلومات الاصلية

Abstract

Exposure to dog bites is an important public health problem , these bites not only cause increase morbidity and mortality but also loss of workers days and cost for treatment , so a cross - sectional retrospective study was carried out during January (2011) to determine the epidemiological profile of dog bite victims registered in the Anti-Rabies clinic of ( Pasteur Institute ) and who live in Baghdad city during (2010) were reviewed data collection then were analyzed by using simple descriptive statistics .The results show that the total number of dog bite victims in Baghdad city during (2010) was 1914 , (79.2%) attended the clinic within the first three days post-exposure with an epidemiological profile which consisted mainly of males (88.5%) , people at risk were mainly children under ten years of age (26.8%) , living in Al- Risafa district (66.6%) . Considerable percentage (74.6%) had injuries involved the lower limbs but a clear seasonal variation in dog bite attacks does not exist .Recommendation was suggested to enhance public awareness through health education , institution of intervention program targeted to control stray dogs and to enhance active animal bite surveillance studies to estimate the true burden of the disease.

التعرض لعضة الكلب هي احدى مشاكل الصحة العامة المهمة ، هذه العضات لاتسبب فقط ازدياد النسبة المراضة والوفيات ، بل ايضا تسبب خسائر مادية من خلال فقدان ايام العمل للعمال وتكاليف العلاج ، لذلك انجزت دراسة مقطعية رجعية في شهر كانون الثاني عام (2011) لغرض تحديد الخصائص الوبائية لضحايا عضات الكلاب المسجلة في معهد باستور ( عيادة الوقاية من داء الكلب ) للساكنين في محافظة بغداد فقط خلال عام (2010) والتي تمت مراجعتها ثم تحليل البيانات من خلال استخدام احصائيات وصفية بسيطة .اظهرت النتائج بأن العدد الكلي لضحايا عضات الكلاب في محافظة بغداد خلال عام (2010) بلغت (1914 ) حالة (%79.25) منهم راجعوا المركز المذكور خلال الايام الثلاثة الاولى بعد التعرض ، كانت لهم خصائص وبائية منحصرة اكثرها في فئة الذكور( %88.5) الاشخاص المعرضون للاصابة كانو اكثر نسبة ضمن فئة الاطفال دون العشر سنوات (%26.8)، الساكنين في قطاع الرصافة (%66.6). ان نسبة ملحوظة منهم (%74.6) لديهم جروح في الاطراف السفلى ولكن لم يتبين وجود تغيرات موسمية واضحة في التعرض لعضات الكلاب .تم تقديم التوصيات لزيادة وعي الناس من خلال التثقيف الصحي , اعداد برامج تنفيذية موجهة لابادة الكلاب السائبة وكذلك التشجيع على اجراء دراسات مسحية فعالة لمعرفة الحجم الحقيقي للمشكلة.
