[Recurrent retroperitoneal hematoma due to viperine envenomation: case study]. / Hématome rétro-péritonéal consécutif à une envenimation vipérine: à propos d'un cas.

Ophidian envenomations are a public health problem in Africa, causing 20.000 annual deaths. This mortality reflects the difficulties in the management of these complications, in particular of bleeding complications. We report the case of Mr SL, aged 35 years, farmer, victim of snake bite causing haemorrhagic syndrome followed by a progressive onset of acute abdomen. Ultrasound objectified high abundant effusion. Effusion puncture was performed which showed unclotting blood. Given the re-establishment of the hemoperitoneum after three doses of antivenin serum as well as the coagulation of the samples collected using drying tube, exploratory laparotomy was performed on day 9. It showed retroperitoneal hematoma, with bulging appearance, in the mesocolon which flowed in the peritoneal cavity. Aspiration of 1500ml of blood and rinsing with physiological serum were performed. The postoperative course was uneventful. The patient was transferred to the department of surgery three days after surgery and was discharged on day 19.

Discrepant prevalence and incidence of Leishmania infection between two neighboring villages in Central Mali based on Leishmanin skin test surveys.

UNLABELLED: Apart from a single report, the last publication of cutaneous leishmaniasis (CL) in Mali dates back more than 20 years. The absence of information on the current status of CL in Mali led us to conduct a cohort study in Kemena and Sougoula, two villages in Central Mali from which cases of CL have been recently diagnosed by Mali's reference dermatology center in Bamako. In May 2006, we determined the baseline prevalence of Leishmania infection in the two villages using the leishmanin skin test (LST). LST-negative individuals were then re-tested over two consecutive years to estimate the annual incidence of Leishmania infection. The prevalence of Leishmania infection was significantly higher in Kemena than in Sougoula (45.4% vs. 19.9%; OR: 3.36, CI: 2.66-4.18). The annual incidence of Leishmania infection was also significantly higher in Kemena (18.5% and 17% for 2007 and 2008, respectively) than in Sougoula (5.7% for both years). These data demonstrate that the risk of Leishmania infection was stable in both villages and confirm the initial observation of a significantly higher risk of infection in Kemena (OR: 3.78; CI: 2.45-6.18 in 2007; and OR: 3.36; CI: 1.95-5.8 in 2008; P<0.005). The absence of spatial clustering of LST-positive individuals in both villages indicated that transmission may be occurring anywhere within the villages. Although Kemena and Sougoula are only 5 km apart and share epidemiologic characteristics such as stable transmission and random distribution of LST-positive individuals, they differ markedly in the prevalence and annual incidence of Leishmania infection. Here we establish ongoing transmission of Leishmania in Kemena and Sougoula, Central Mali, and are currently investigating the underlying factors that may be responsible for the discrepant infection rates we observed between them.
