BackgroundSchistosomiasis is classically described as a rural disease that occurs in areas with poor sanitary conditions. However, over recent decades, there has been an expansion of schistosomiasis foci towards urban areas faced with a rapid and disordered urbanization. In Bamako, Mali, the impact of environmental change on vector-borne diseases such as schistosomiasis is not well known. This study sought to identify the presence of schistosomiasis transmission hotspots in Bamako. Using this perspective, we aimed to describe the risk factors of the endemization and maintenance of schistosomiasis.Materials and methodsA cross-sectional study was carried out in the six municipalities (communes) in Bamako. Environmental information was obtained from earth observation satellites in order to maximize ecological contrasts. Twenty-nine blocks of 200 m x 200 m were identified. We selected a school inside or nearest to each block for urine and stool samples examination. The study cohort was school children aged between eight and 15 years. The Kato-Katz technique and filtration were used for Schistosoma mansoni and S. haematobium ova research in stools and urine, respectively. The schools and snail breeding sites were georeferenced. Four malacological surveys were conducted between October 2011 and February 2012. Bivariate analysis was used to identify independent predictors of being infected with schistosomiasis.ResultsThe prevalence rate of S. haematobium was 14.7% (n = 1,761) and that of S. mansoni 1.5% (n = 1,491). Overall, the urinary form was endemic in 76.6% of schools. The infection significantly varied between the municipalities (p < 0.001). It was also more prevalent on the left side of the Niger River than the right side (17.4% vs. 9.5% respectively; p < 0.001). The vicinity to snail breeding sites (OR = 3.677; 95% IC [2.765–4.889]; p < 10-3) and parents’ occupations (OR = 7.647; 95% IC [2.406–24.305]; p < 0.001) were the most important risk factors associated with S. haematobium infection exposure. Biomphalaria pfeifferi, Bulinus truncatus, and B. globosus were the intermediate hosts captured. The schistosome natural infection rates (SNIRs), which were low or nil in October and November, rose to 2.8% in January and 8.3% in February for B. pfeifferi and B. truncatus, respectively.ConclusionOur findings show that there is a high transmission risk for schistosomiasis in Bamako. Appropriate integrated control measures need to be introduced to control the transmission of this disease in the study area.Electronic supplementary materialThe online version of this article (doi:10.1186/2049-9957-4-4) contains supplementary material, which is available to authorized users.

Purpose: To describe the aspects of the positive diagnosis of large goiters. Patients and Methods: We conducted a retrospective and prospective study including 115 patients from January, 2009 till December, 2014 (6 years) in Central Hospital of University of Point G in Bamako (Mali). The diagnosis of large goiters was based on the measurements of the anterior neck swelling. Thus large goiter was defined as any goiter including the height or width was greater than or equal to 10 cm (centimeters). Results: We operated 115 cases of large goiters on 760 goiters operated either 15.1%. The average age of patients was 44, 43 years ±14, 3 with extremes of 9 and 80 years. There was 101 women (87.8%) and 14 men (12.2%) with a sex ratio of 7.2 in favor of women. The signs of compression were dyspnea in 40% of cases (46/115), dysphonia in 13.0% (15/115), and dysphagia in 8.6% (10/115). The average height of goiter was 12.1 cm ± 3.5 cm with extremes of 10 and 29 cm and the average width was 14.4 cm ± 5.4 cm with extremes of 10 and 32 cm. Thyroid ultrasound found large goiters multinodular in 100%. Cervical radiography found the tracheal deviation in 48.2% (42/87), tracheal compression in 20.6% (18/87), plunging goiters in 11.5% (10/87). Cytology found a benign goiter in 97.4% of cases (112/115), malignant (thyroid cancer) in 2.6% of cases (3/115). Conclusion: Diagnosis of large goiters was based on the measurement of the swelling in our context. The signs of compression are the severity of this condition.

Introduction: Cervical cystic lymphangiomas are rare benign dysembryoplastic tumors of lymphatic origin. Its severity in the child is due on one hand to their fast evolution and the compression of the way aerodigestive and on the other hand, by the classical difficulty of their excision. The purpose of this work was to report a case of giant cervical cystic lymphangioma in a child to discuss the difficulties associated with its management in our context. Observation: This was a 3-year-old female child who was admitted to the ENT department of CHU "Luxembourg" for right lateral cervical swelling. The clinical examination had noted a large anterior-latero cervical swelling of soft, renitent, painless palpation, movable in relation to the superficial and deep plane, measuring about 20 cm × 17 cm, the skin was healthy. It wasn't particularity to the rest of the physical examination. The diagnosis of giant cervical cystic lymphangioma was discussed. Thorough excision of the swelling by right lateral cervicotomy was performed. Anatomopathological examination of the operative specimen confirmed the diagnosis. The postoperative course was simple and the evolution was favorable. Conclusion: Cervical cystic lymphangiomas are rare. Their management involves surgery, with short and long-term post-operative outcomes are often excellent.

Objectives were to determine the frequency, describe the epidemiological and clinical aspects, therapeutic and analyze the postoperative course. Methodology: This was a retrospective study that covered 08 years (January 2009-December 2017). Inclusion criteria: all patients operated for obstruction of the small bowel by hail and/or flanging. Exclusion criteria: other types of occlusion and non-operated patients. Result: We recorded a total of 162 cases of hail obstruction by adhesions and/or flanges at 2.87%. The average age was 32.04, the sex ratio was 1.2. The average consultation time was 4 days. Abdominal pain associated with stopping of material and gas was present in all our patients. X-ray of the abdomen without preparation carried out in all the patients made it possible to objectify in 150 patients (92.6%) of the hydro-hail levels. Inoperative occlusion of hail on flange was present in 80 patients (49.4%). Occlusion of the small bowel on flange and adhesion was present in 69 patients. Adhesion obstruction of hail accounted for 6.8% (11 cases). The most commonly used surgical technique was flange resection in 91 patients (56.2%). The follow-up was simple in 151 patients (93.2%). Mortality was 1.2% of cases, i.e. 2 deaths. The average duration of hospitalization was 6 days. Conclusion: Occlusion of the small bowel by flanging and/or adherence is a surgical emergency whose prognosis depends on early management.
