RESUMO
Contexte & objectif L'uvéite est peu très peu documentée en Niamey. L'objectif de la présente étude était de décrire les aspects épidémiologique et clinique des uvéites. Méthodes. Il s'agissait d'une étude rétrospective et descriptive portant sur 127 dossiers des patients suivis pour uvéites à la clinique lumière de Niamey sur une période de 5 ans (2015 2020). Les paramètres sociodémographiques, cliniques et thérapeutiques ont été recueillis. Résultats. La fréquence hospitalière des uvéites était de 0,21 %. Le sex-ratio était de 1,01. L'âge moyen des patients était de 40,76 ans. La douleur oculaire représentait le motif de consultation le plus fréquent avec 51 ,97 %. La majorité des patients avait présenté 2 épisodes d'uvéites soit 57,48 %. L'atteinte était unilatérale dans 70,97 % et les uvéites antérieures étaient les plus fréquentes 66,93 %. Les étiologies étaient identifiées chez seulement 7,87 % des patients dont près de la moitié était la tuberculose. 33,07 % des patients avaient présenté des complications. Conclusion. Il ressort de cette étude que l'uvéite touche plus des jeunes adultes, ses étiologies sont indéterminées dans la majorité de cas. Les formes antérieures sont plus fréquentes.
Context and objective Little is known about Uveitis in Niamey. This study aimed to analyze the epidemiological and clinical aspects of uveitis. Methods. This was a retrospective, descriptive study of 127 records of patients followed up for uveitis at the Niamey Lumière Clinic over a 5-year period (2015 2020). Sociodemographic, clinical and therapeutic parameters were collected. Results. The hospital frequency of uveitis was 0.21%. The sex ratio was 1.01. The mean age of patients was 40.76 years. Ocular pain was the most frequent reason for consultation, accounting for 51.97 %. The majority of patients (57.48%) had presented with 2 episodes of uveitis. Involvement was unilateral in 70.97 %, and anterior uveitis was the most frequent, at 66.93 %. Etiologies were identified in only 7.87 % of patients, of which tuberculosis accounted for almost half. Complications occurred in 33.07 % of patients. Conclusion. This study shows that uveitis affects mainly young adults, and its etiologies are undetermined in most cases. Anterior forms are more frequent.

OBJECTIVES: The relationship between electromagnetic field exposure and stillbirth has not been evaluated. We assessed associations between residential proximity to extremely low frequency power transmission lines and stillbirth across gestational age. METHODS: Data included singleton live births (N=514,826) and stillbirths (N=2033) for 1998-2007 in metropolitan areas of Québec, Canada. Using power transmission line maps, the distances between lines and residential six-digit postal codes (<25, 25-49.9, 50-74.9, 75-99.9, ≥ 100 m) were calculated. Generalised estimating equations were used to compute ORs and 95% CIs for distance and stillbirth, accounting for individual and area characteristics. Early preterm (< 28 weeks), late preterm (28-36 weeks) and term (≥ 37 weeks) stillbirths were examined relative to fetuses-at-risk. RESULTS: There was no association between distance and preterm stillbirth. The odds of term stillbirth for <25 m were greater compared to ≥ 100 m (OR 2.25, 95% CI 1.14 to 4.45), but no dose-response pattern was apparent. CONCLUSIONS: A graded dose-response trend between distance to lines and odds of stillbirth was not found, but the likelihood of term stillbirth was elevated for residences within 25 m of power transmission lines. Residential proximity to transmission lines is unlikely to be associated with stillbirth, but more research is needed to rule out a possible link.
