Relation entre exposition professionnelle des manipulateurs de déchets d'équipements électriques et électroniques et problèmes respiratoires à Bamako en 2019 / Relationship between occupational exposure of waste electrical and electronic equipment handlers and respiratory problems in Bamako in 2019

Introduction: les déchets d'équipements électriques et électroniques (D3E), avec leurs enjeux sanitaires et environnementaux, sont devenus un problème de santé publique exposant les travailleurs aux composés d'éléments toxiques responsables de (2ème expertise) troubles respiratoires. Objectif: Etudier la relation entre l'exposition professionnelle aux D3E et la survenue des problèmes respiratoires à Bamako en 2019. Matériel et Méthodes : Il s'agissait d'une étude transversale, analytique de 6 mois, menée dans la ville de Bamako en 2019 et concernait 159 manipulateurs de D3E. Les données ont été collectées sur tablette et les analyses univariées et multivariées réalisées sur SPSS version 22 au seuil de significativité de 0,05 avec présentation des Odds Ratio (OR) et leurs intervalles de confiance à 95% (OR[IC95%]). Résultats : La prévalence en général des troubles respiratoires était de 67,3% chez les manipulateurs des D3E. On notait que le retrait du revêtement des fils électroniques (OR[IC95%] =25,93[2,30;291,53]), la perte de poids récente en dehors d'un régime (OR[IC95%] =7,43[1,68;32,85]) et la rareté de lavage des mains avec du savon après les toilettes (OR[IC95%] =11,50[2,07;63,89]) représentaient un risque plus élevé de problèmes respiratoires. Conclusion :Ces résultats montrent que les manipulateurs de D3E ont beaucoup de comportement à risque des problèmes respiratoires. Cette étude pourrait servir à la mise en œuvre de stratégies visant à réduire l'impact des D3E

Introduction: waste electrical and electronic equipment (WEEE), with its health and environmental issues, has become a public health problem exposing workers to toxic compounds causing respiratory problems. Objective: To study the relationship between professional exposure to WEEE and the occurrence of respiratory problems in Bamako in 2019. Material and Methods: This was a 6-month cross-sectional, analytical study carried out in the city of Bamako in 2019 and involved 159 WEEE manipulators. Data were collected using a tablet (2). Univariate and multivariate analyzes were performed using SPSS version 22 with the significance level of 0.05. Odds Ratio (OR) were presented with their 95% confident interval (OR [95%CI]). Results: The overall prevalence of respiratory disorders was 67.3% among WEEE handlers. It was noted that the removal of the coating of electronic wires (OR [95%CI] =25.93[2.30;291.53]), recent weight loss outside of a diet (OR [95% CI] =7,43[1.68;32.85]) and the infrequent hand washing with soap after the toilet (OR [95% CI] =11.50[2.07; 63.89]) represented a higher risk of (2) breathing problems. Conclusion: These results show that D3E handlers have a lot of risky behavior for respiratory problems. This study could be used to implement strategies to reduce the impact of D3E

CT manifestation of schistosoma haematobium cystitis / 中华放射学杂志

Objective To analyze CT manifestation of Schistosoma haematobium cystitis.Methods Retrospective analysis 32 patients,who were tested for Schistosoma haematobium cystitis using the urine filtration method.CT scan was performed for each patient with contrast enhancement.Results The vast majority of urinary tract schistomiasis lesions were in the urinary bladder.Calcification of the bladder wall was observed in all patients and mild enhancement in non calcified zone was found after intravenous contrast.Except for 5 patients of bladder cancer,the rest were no abnormality in size of bladder when bladder was filling or emptying.Ureteral wall annular calcification could also be identified in 25 patients.Twenty two patients were companied with ureteric hydronephrosis.Seminal vesicle calcification was seen in 4 patients among 11 male patients,while both uterine and ovarian in female and prostate in men had non calcification.Serious illness can be combined with bladder cancer.In 5 patients of patients with bladder cancer,bladder showed irregular soft tissue mass which was enhanced moderately after post-contrast scan,with vesical calcification in mass medially.Conclusion Bladder calcification is the most prominent CT feature of Schistosoma haematobium cystitis,which is useful in diagnosis the disease.
