    L'objectif était d'étudier l'aspect épidémio-clinique et thérapeutique de la hernie inguinale selon la technique de Shouldice. Nous avons réalisé une étude  rétrospective, portant sur les patients opérés pour hernie inguinale selon la technique de Shouldice dans le service de chirurgie B du CHU du Point G, Bamako, Mali. Il a été  enregistré 225patients opérés selon la technique de Shouldice. L'âge moyen était de 49 ans +/- 17,7. Il y avait 90,7% (204) hommes soit un sex-ratio de 9,7. Les cultivateurs, les ménagères et les ouvriers ont représenté 51,1% (115). Dans 75,2% (169) les patients ont consulté pour tuméfaction inguinale. En pré opératoire, la hernie était compliquée chez 82 (36,4%) patients dont 24 cas de récidive. L'étranglement herniaire a été la principale complication pré opératoire  58,5% (48/82). Les suites opératoires à un an ont été simples chez 94,2%(210) des patients; elles étaient marquées par 8 cas de récidive, 4 cas de névralgie, 2  cas d'atrophie testiculaire, 1 cas de chéloïde. La technique de Shouldice est la technique de choix pour la cure de la hernie inguinale dans les pays en voie de  développement à cause du bon résultat et son coût peu onéreux par rapport aux autres techniques utilisant des dispositifs médicaux.Key words: Hernie inguinale, technique de Shouldice, récidive

    Objective: To carry out a 3D vector reconstruction of the nerves of the ventral region of the neck from anatomical sections of the “Korean Visible Human” for educational purposes. Materials and Methods: The anatomical subject was a 33-year-old Korean man who died of leukemia. He was 164cm tall and weighed 55kgs. A cryomacrotome sectioned the frozen body into 5960 sections. Sections numbered 1500 to 2000 were used for this study. A segmentation by manual contouring of each nervous anatomical element of the ventral region of the neck was done using Winsurf version 3.5 software on a laptop PC running Windows 10 equipped with an 8 gigabyte RAM. Results: Our vector 3D model of nerves in the ventral neck region includes the brachial plexuses, vagus nerves, inferior and superior laryngeal nerves, glossopharyngeal nerves, hypoglossal nerves and spinal nerves. This vector model has been integrated into the Diva3d virtual dissection table. It was also uploaded to the Sketchfab website and 3D printed using an ENDER 3 printer. Conclusion: Our 3D reconstruction of the nerves of the ventral region of the neck is an educational tool for learning the nerves of the ventral region of the neck and can also serve as a 3D atlas for simulation purposes for training in therapeutic gestures

    Multicentre studies of insecticide-treated durable wall lining in Africa and South-East Asia: entomological efficacy and household acceptability during one year of field use.

    BACKGROUND: Indoor residual spraying (IRS) is a primary method of malaria vector control, but its potential impact is constrained by several inherent limitations: spraying must be repeated when insecticide residues decay, householders can tire of the annual imposition and campaign costs are recurrent. Durable lining (DL) can be considered an advanced form of long-lasting IRS where insecticide is gradually released from an aesthetically attractive wall lining material to provide vector control for several years. A multicentre trial was carried out in Equatorial Guinea, Ghana, Mali, South Africa and Vietnam to assess the feasibility, durability, bioefficacy and household acceptability of DL, compared to conventional IRS or insecticide-treated curtains (LLITCs), in a variety of operational settings. METHODS: This study was conducted in 220 households in traditional rural villages over 12-15 months. In all sites, rolls of DL were cut to fit house dimensions and fixed to interior wall surfaces (usually with nails and caps) by trained teams. Acceptability was assessed using a standardized questionnaire covering such topics as installation, exposure reactions, entomology, indoor environment, aesthetics and durability. Bioefficacy of interventions was evaluated using WHO cone bioassay tests at regular intervals throughout the year. RESULTS: The deltamethrin DL demonstrated little to no decline in bioefficacy over 12-15 months, supported by minimal loss of insecticide content. By contrast, IRS displayed a significant decrease in bioactivity by 6 months and full loss after 12 months. The majority of participants in DL households perceived reductions in mosquito density (93%) and biting (82%), but no changes in indoor temperature (83%). Among those households that wanted to retain the DL, 73% cited protective reasons, 20% expressed a desire to keep theirs for decoration and 7% valued both qualities equally. In Equatorial Guinea, when offered a choice of vector control product at the end of the trial (DL, IRS or LLITCs), DL consistently emerged as the most popular intervention regardless of the earlier household allocation. CONCLUSIONS: Just as long-lasting insecticidal nets overcame several of the technical and logistical constraints associated with conventionally treated nets and then went to scale, this study demonstrates the potential of DL to sustain user compliance and overcome the operational challenges associated with IRS

    DĂ©centralisation et pouvoirs en Afrique

    No full text
    Depuis les années 1990, de nombreux pays africains ont engagé des décentralisations administratives, soutenus en cela par les instances internationales. Ces réformes, qui s’inscrivent à une échelle globale, bousculent les équilibres antérieurs entre différents pôles de pouvoir et redéfinissent les relations entre États et sociétés civiles. À travers une décennie d’évolution, éclairée par une histoire de longue durée, des anthropologues, géographes, historiens, politistes, socio-linguistes analysent ces processus dans cinq pays d’Afrique. Ils décrivent les nouvelles formes de compétition autour des pouvoirs et du contrôle des ressources, mais soulignent aussi l’émergence de dynamiques novatrices, conjuguant communautés et citoyenneté. Une mise en regard avec l’histoire de la décentralisation et la genèse des « pays » en France apporte des éclairages inattendus sur les relations Nord/Sud, du double point de vue de la circulation des modèles et de l’existence de paradoxes communs. Ce livre intéressera tous ceux – chercheurs, acteurs ou institutions – qui travaillent sur la décentralisation, et, plus largement, sur les refontes des États en temps de mondialisatio

    <div><p>Background</p><p>In 2009, three years after stopping mass treatment with azithromycin, a trachoma impact survey in four health districts in the Kayes region of Mali found a prevalence of trachomatous inflammation—follicular (TF) among children aged 1 to 9 years of >5% and a trachomatous trichiasis (TT) prevalence within the general population (≥1-year-old) of <1%. As a result, the government’s national trachoma program expanded trichiasis surgery and related activities required to achieve trachoma elimination.</p><p>Methodology/Principal findings</p><p>In 2015, to assess progress towards elimination, a follow-up impact survey was conducted in the Kayes, Kéniéba, Nioro and Yélimané health districts. The survey used district level two-stage cluster random sampling methodology with 20 clusters of 30 households in each evaluation unit. Subjects were eligible for examination if they were ≥1 year. TF and TT cases were identified and confirmed by experienced ophthalmologists. In total 14,159 people were enumerated and 11,620 (82%) were examined. TF prevalence (95% confidence interval (CI)) was 0.5% (0.3–1%) in Kayes, 0.8% (0.4–1.7%) in Kéniéba, 0.2% (0–0.9%) in Nioro and 0.3% (0.1–1%) in Yélimané. TT prevalence (95% CI) was 0.04% (0–0.25%) in Kayes, 0.29% (0.11–0.6%) in Kéniéba, 0.04% (0–0.25%) in Nioro and 0.07% (0–0.27%) in Yélimané.</p><p>Conclusions/Significance</p><p>Eight years after stopping MDA and intensifying trichiasis surgery outreach campaigns, all four districts reached the TF elimination threshold of <5% and three of four districts reached the TT elimination threshold of <0.1%.</p></div
