[Management of hand burns: clinical and epidemiological aspects and therapy at CHU Gabriel Toure]. / Sequelles de brulure de la main: aspects epidemio-cliniques et therapeutiques au CHU Gabriel Toure.

AIM: Evaluate the care of burn sequel of the hand in the services of orthopaedic trauma and paediatric in the teaching hospital Gabriel Touré. METHODS: It was about a longitudinal and prospective study lasting from Jun 2006 to January 2008 in all the children aged from 0 to 14 years with burn sequel of the hand admitted and treated in the services of orthopaedic- trauma and paediatric surgery of Gabriel Touré. Patients with an incomplete file or lost during the study were not included. RESULTS: In 20 months we brought together 40 cases of burn sequel of hand. The mean age of the patients was 8.5 years. There were 18 boys and 22 girls. The sex-ratio was 1.22 for girls. The causal agent was more frequently thermal (85%) by hot liquid. Burn was caused by domestic accident in 95%. 14 of our patients were seen by a doctor after 24 months of burn and another 14 were after 36 months. A functional deficit was noted to the physical examination in all our patients. The treatment was surgical in 26 patients. Results were judged well in 16 cases, little good in 8 and bad 2 case. A good initial treatment done in a fear condition permit to reduce the number of sequel of the hand and to stay less severe.

[Reinfection with Schistosoma haematobium and mansoni despite repeated praziquantel office treatment in Niger, Mali]. / Réinfections par Schistosoma haematobium et mansoni à l'office du Niger au Mali malgré la prise répétée de praziquantel.

The dynamics of reinfection by Schistosoma haematobium and Schistosoma mansoni after repeated treatment with praziquantel (40 mg/kg body weight, single dose) was studied in a cohort of schoolchildren living in an endemic area. A total of 214 urine and 220 stool samples were collected and examined at three different times, i.e., February 1989, July 1989 and February 1990. Mass chemotherapy was administered at the beginning of study (February 89). Treatment was repeated in children with positive tests at each subsequent sampling. Prevalence rates were 55.1 p. 100, 3.7 p. 100, and 35.0 p. 100 for Schistosoma haematobium and 62.7 p. 100, 46.3 p. 100 and 73.1 p. 100 for Schistosoma mansoni in February 1989, July 1989 and February 1990 respectively (p < 0.001). From July 1989 to February 1990, reinfection was observed in 84.5 p. 100 of children by Schistosoma haematobium versus 57.8 p. 100 by Schistosoma mansoni. The risk of reinfection by Schistosoma haematobium was higher in children between the ages of 7 and 10 years than in children between the ages of 11 and 15 years (p < 0.001), The incidence of intense Schistosoma haematobium egg excretion rose from 0 p. 100 in July 1989 to 6.0 p. 100 in February 1990. The incidence of intense Schistosoma mansoni excretion in February 1990 was 4.5 p. 100. The reinfection rate at 7 months was over 50 p. 100 for both parasite species despite repeated treatment. This finding demonstrates that additional measures such as proper sanitation and vector control are needed to control human schistosomiasis in irrigated rice paddies.

[Epidemiology of human urban schistosomiasis in Bamako in Mali (the case of the "populous" quarter of Bankoni)]. / Epidémiologie des Schistosomiases humaines urbaines a Bamako au Mali (le cas du quartier "populeux" de Bankoni).

From may 1989 to january 1990, we have studied parasitologic index in snails population, stools and urines examination in children (1-15 years) in one of the greatest "spontaneous" quarter of Bamako. 584 stools samples and 563 urines were tested. 4.717 snails were captured during six months. From all these data, we conclude that in Bankoni S. haematobium is mesoendemic (36.6%) and S. mansoni hypoendemic (3.4%). B. truncatus is the most important host for urogenital schistosomiasis. The two seasonal revers (Tienkole and Bankoni) are unfavourable to B. pfeifferi's production. B. globosus and B. forskalii are not frequent in this suburban area. This investigation, shows that a selective mass treatment with praziquantel is the better public health care strategy in Bankoni quarter.
