Item Epidemiology of goitre in Sri Lanka in the post-iodization era(Sri Lanka Medical Association, 2015) Fernando, R.; Pathmeswaran, A.; Pinto, M. D.INTRODUCTION: Previous studies of goitre in Sri Lanka proposed the presence of a goitre belt, which was refuted subsequently. Epidemiology of goitre in the post iodization era needs re-evaluation. Objectives To describe the epidemiology of goitre in Sri Lanka. METHODS: A descriptive cross-sectional study was conducted in designated zones except in conflict areas in 2006/2007. An interviewer administered questionnaire was used and patients were evaluated clinically, biochemically and cytologically. RESULTS: Among 5200 participans 426 had goitre. Mean age was 36.3 (SD 17.3) years. Goitre was commonest in the age group 40-49 years with a female pre-ponderance. The prevalence was similar in all zones with pockets of high prevalence in each zone. Overall islandwide adjusted prevalence was 6.8% (95% CI = 6.0-7.6). CONCLUSIONS: There was no identifiable goitre belt.There were pockets of high prevalence in all zones. Goitre remains a public health issue despite universal iodization.Item Epidemiology of irritable bowel syndrome in children and adolescents in Asia(Lippincott Williams and Wilkins, 2015) Devanarayana, N.M.; Rajindrajith, S.; Pathmeswaran, A.; Abeygunasekara, C.; Gunawardena, N.K.; Benninga, M.A.OBJECTIVES: Several cross-sectional surveys have been conducted to study the prevalence of irritable bowel syndrome (IBS) in children. The aim of the present study was to conduct a systematic review and a meta-analysis of published literature to estimate the prevalence of IBS among Asian children. METHOD: A computer-assisted search of MEDLINE, EMBASE, PsycINFO, and regional databases of Asia was carried out. Selected articles were reviewed in depth and data were extracted. Pooled prevalence, sex differences, and 95% confidence intervals were calculated. Heterogeneity of the studies was assessed using the I(2) test. RESULTS: A total of 16 cross-sectional studies that reported prevalence of IBS (in children and adolescents) and qualified to be included were taken into the final analysis containing 38,076 patients. Selected studies are from China, Korea, Japan, Iran, Sri Lanka, and Saudi Arabia. Studies showed a marked heterogeneity with I(2) of 98.59 (P < 0.0001). Prevalence of IBS ranges from 2.8% to 25.7%, with a pooled prevalence of 12.41% (95% confidence interval 9.87-14.95). Prevalence risk ratio of girl:boy is 1.39. Prevalence of subtypes is diverse and varies between studies. CONCLUSIONS: The published data indicate that IBS is a significant problem among Asian children and adolescents. Female sex predisposes children and adolescents to develop IBS.
