    Background: A cluster of suspected shigellosis was reported from health center in Pemagatshel district to Royal Center for Disease Control on 14th May 2012. The investigation was done to determine the cause and risk factor for the outbreak so that appropriate control and prevention measures can be implemented. Methods: A descriptive study was used for the outbreak investigation. The food items and drinks served to boarding students were collected from the mess in-charge in order to assess their risk for the outbreak. The kitchen and its premises were inspected to study the likely contamination by rodents and other animals. The water and stool specimens were tested in the laboratory to identify all possible enteric pathogens. Results: 82 boarding students were affected with an overall attack rate of 28% (82/294). Diarrhea was the predominant symptom followed by abdominal pain and headache. The onset date of the cases varied between 11th and 18th May, 2012. Shigella species was isolated from stool specimens that showed resistant to amoxicillin, nalidixic acid, chloramphenicol and sulfamethoxazole. Water specimen collected from source, distribution reservoir and tap water at school were found grossly contaminated. Conclusion: The outbreak was caused by novel strain of Shigella species which was not detected earlier in Bhutan. The promotion and provision of boiled water will greatly reduce the incidence of shigellosis especially in boarding facility

    PURPOSE: The purpose of this meta-analysis is to study the impact of varicocele repair in the largest cohort of infertile males with clinical varicocele by including all available studies, with no language restrictions, comparing intra-person conventional semen parameters before and after the repair of varicoceles. MATERIALS AND METHODS: The meta-analysis was performed according to PRISMA-P and MOOSE guidelines. A systematic search was performed in Scopus, PubMed, Cochrane, and Embase databases. Eligible studies were selected according to the PICOS model (Population: infertile male patients with clinical varicocele; Intervention: varicocele repair; Comparison: intra-person before-after varicocele repair; Outcome: conventional semen parameters; Study type: randomized controlled trials [RCTs], observational and case-control studies). RESULTS: Out of 1,632 screened abstracts, 351 articles (23 RCTs, 292 observational, and 36 case-control studies) were included in the quantitative analysis. The before-and-after analysis showed significant improvements in all semen parameters after varicocele repair (except sperm vitality); semen volume: standardized mean difference (SMD) 0.203, 95% CI: 0.129-0.278; p\u3c0.001; I²=83.62%, Egger\u27s p=0.3329; sperm concentration: SMD 1.590, 95% CI: 1.474-1.706; p\u3c0.001; I²=97.86%, Egger\u27s p\u3c0.0001; total sperm count: SMD 1.824, 95% CI: 1.526-2.121; p\u3c0.001; I²=97.88%, Egger\u27s p=0.0063; total motile sperm count: SMD 1.643, 95% CI: 1.318-1.968; p\u3c0.001; I²=98.65%, Egger\u27s p=0.0003; progressive sperm motility: SMD 1.845, 95% CI: 1.537%-2.153%; p\u3c0.001; I²=98.97%, Egger\u27s p\u3c0.0001; total sperm motility: SMD 1.613, 95% CI 1.467%-1.759%; p\u3c0.001; l2=97.98%, Egger\u27s p\u3c0.001; sperm morphology: SMD 1.066, 95% CI 0.992%-1.211%; p\u3c0.001; I²=97.87%, Egger\u27s p=0.1864. CONCLUSIONS: The current meta-analysis is the largest to date using paired analysis on varicocele patients. In the current meta-analysis, almost all conventional semen parameters improved significantly following varicocele repair in infertile patients with clinical varicocele
