Dacryoadenite tuberculeuse bilatérale: à propos d’un cas

La dacryoadénite tuberculeuse est une inflammation rare de la glande  lacrymale causé par le bacille Mycobacterium tuberculosis. Elle pose unproblème étiopathogénique et diagnostique. Nous rapportons dans cette observation le cas d'une dacryoadénite tuberculeuse bilatérale chez unjeune homme Marocain de 34 ans ayant présenté une tuberculose  ganglionnaire et du cavum il y à 14 ans, ayant été confirmé par l'examenanatomopathologique. La tuberculose reste un diagnostic qui doit être  toujours évoqué même dans les atteinte bilatérale surtout si il y a unantécédent personnel ou familiale positif de tuberculose. Le pronostic de cette affection est devenu favorable grâce au traitement antibacillaire précoce

Spatio-temporal patterns of pre-eclampsia and eclampsia in relation to drinking water salinity at the district level in Bangladesh from 2016 to 2018

This analysis examines whether salinity in drinking water is associated with pre-eclampsia and eclampsia (PE/E), a leading cause of maternal morbidity and mortality. Bangladesh’s national health information system data were extracted at the district level (n = 64) to assess PE/E rates, and these were overlaid with three environmental measures approximating drinking water salinity, remotely sensed low-elevation coastal zone (LECZ), monthly rainfall data, and electrical conductivity of groundwater (i.e., water salinity). Results from a negative binomial fixed effects model suggest PE/E rates are higher with less rainfall (dry season), lower population density, and that district level rates of PE/E increase with higher groundwater salinity and in the high risk LECZ category closest to the coast. Results suggest that drinking water salinity may be associated with PE/E and that using national health surveillance data can improve understanding of this association. This approach can potentially be leveraged in the future to inform targeted interventions to high risk regions and times

Latent energy storage: Melting process around heating cylinders

AbstractA physical model to investigate the melting process around a multiple of heating cylinders in the presence of the natural convection has been carried out. A numerical code is developed using an unstructured finite-volume method and an enthalpy porosity technique to solve for natural convection coupled to solid-liquid phase change. It is found that during the melting process around the cylinders, natural convection circulation around each cylinder interacts with the other cylinders to influence the melt shape. In addition to natural convection, the heat source arrangement is an important factor in determining the melt shape

Melting inside a Horizontal Cylindrical Capsule

International audienceThe role of natural convection on solid-liquid interface motion during constrained melting within a horizontal cylindrical capsule was investigated. A numerical code is developed using an unstructured finite-volume method and an enthalpy porosity technique to solve for natural convection coupled to solid-liquid phase change. Flow patterns for different Rayleigh numbers are presented. The resulting melt shapes and the temperature in the PCM provide conclusive evidence of the importance of natural convection on heat transfer in the melt region
