Les fractures de l’extrémité proximale de l’humérus chez l’enfant au CHU Tokoin de Lomé

This retrospective study, carried on files of children treated between January 2005 and December 2009 from humerus upper end fractures (HUEF), aimed to specify the epidemiological, diagnostic and therapeutic aspects of these fractures in the Tokoin Teaching Hospital of Lome. Results: During 5 years, 10 children (6 girls and 4 boys) were treated from HUEF. The HUEF represented 9% of humerus fractures and 1.39% of children fractures. The HUEF were due 8 times to game and sport accidents, and 2 times to home accidents. The shoulder pain, present in all cases, was associated with functional disability, absolute in 8 cases, and relative in 2 cases. The fracture was associated with concussion in one case. The shoulder x-ray showed that the fracture was metaphyseal 6 times, and epiphyseal 4 times. In any case, orthopedic treatment led to very good results.Conclusion: Even though the orthopedic treatment leads to very good results in the majority of cases, an early treatment helped with image intensifier when required is the guarantee of satisfactory results.Keywords: Fractures, humerus, children, Togo.J.

Epidemiology of onchocerciasis-associated epilepsy in the Mbam and Sanaga river valleys of Cameroon: Impact of more than 13 years of ivermectin

Background: A high epilepsy prevalence has been reported in several onchocerciasis-endemic villages along the Mbam and Sanaga river valleys in Cameroon, including Bilomo and Kelleng. We sought to determine the prevalence of epilepsy in these two villages following more than 13 years of community-directed treatment with ivermectin (CDTI). Methods: Door-to-door surveys were performed on the entire resident population in the villages in August 2017 and January 2018. Epilepsy was diagnosed using a 2-step approach: administration of a standardized 5-item questionnaire followed by confirmation by a neurologist. Previously published diagnostic criteria for onchocerciasis-associated epilepsy (OAE) were used. Ov16 serology was done for children aged 7-10 years to assess onchocerciasis transmission. Findings were compared with previous data from these two villages. Results: A total of 1525 individuals (1321 in Bilomo and 204 in Kelleng) in 233 households were surveyed in both villages. The crude prevalence of epilepsy was 4.6% in Bilomo (2017) and 7.8% in Kelleng (2018), including 12 (15.6% of cases) persons with epilepsy (PWE) with nodding seizures. The age and sex-standardized prevalence in Kelleng decreased from 13.5% in 2004 to 9.3% in 2018 (P < 0.001). The median age of PWE shifted from 17 (IQR: 12-22) years to 24 (IQR: 20-30) years in Bilomo (P < 0.001); and slightly from 24 (IQR: 14-34) years to 28 (IQR: 21.25-36.75) years in Kelleng (P = 0.112). Furthermore, 47.6% of all tested children between 7 and 10 years had Ov16 antibodies. Conclusions: There is a decrease in epilepsy prevalence after 13 years and more of CDTI in both villages. The age-shift observed in PWE suggests that ivermectin may prevent OAE in younger residents. Ov16 seropositivity in children indicates ongoing onchocerciasis transmission possibly due to suboptimal control measures. Our findings support the existence of OAE in Cameroon and highlight the need to strengthen onchocerciasis elimination programs.SCOPUS: ar.jinfo:eu-repo/semantics/publishe
