Le diagnostic du volvulus du grêle peut se faire en urgence devant un tableau d´occlusion intestinale aiguë, voire un état de choc ou devant des douleurs abdominales répétées associées souvent à des troubles du transit. C´est une complication redoutable du mésentère commun incomplet, qui est définie comme une anomalie de rotation du tube digestif très rare à l´âge adulte. Sa symptomatologie clinique est non spécifique, d´où l´intérêt de connaitre ses caractéristiques radiologiques surtout scannographiques, permettant ainsi une prise en charge thérapeutique précoce. Nous rapportons l´observation d´un patient de 65 ans admis pour volvulus total du grêle sur mésentère commun incomplet diagnostiqué par tomodensitométrie (TDM) abdominale et confirmé par l´exploration chirurgicale, et chez qui l´évolution était favorable.

La maladie de Creutzfeld-Jacob (MCJ) est une affection très rare et fatale qui atteint le système nerveux central. Elle est caractérisée par une détérioration mentale aboutissant à une démence progressive, une symptomatologie pyramidale et extra-pyramidale ainsi que des myolclonies. Un diagnostic précoce est essentiel pour prévenir la transmission interhumaine. Nous rapportons le cas d'un patient âgé de 62 ans chez qui le diagnostic de MCJ sporadique a été retenu, en se basant sur le tableau clinique fait de syndrome démentiel avec myoclonies précédées de troubles du comportement, des hallucinations et de dépression, et sur les données de l'IRM encéphalique qui a montré des hyper signaux au niveau du striatum et au niveau cortical en séquences pondérées Flair et diffusion.

Purpose: End-stage renal disease patients (ESRD) generally complain about a poor quality of life (QOL). The current study aims to describe and compare ESRD patients' QOL according to dialysis modalities (hemodialysis [HD] and peritoneal dialysis [PD]).Methods: This is a cross-sectional study, conducted in dialysis facilities of a Moroccan university hospital, during October 2018. All adult ESRD patients, treated either by HD or PD for more than 3 months and agreeing to participate, were included. Medical data were collected using a questionnaire, whereas the QOL data were collected using the Kidney Disease Quality of Life Short Form (KDQOL SF v 1.3) scale previously validated in dialectal Arabic. The patients' characteristics and QOL data were compared between dialysis modalities (HD vs. PD), using a linear regression, before and after adjustment on several demographic and medical factors as well as a propensity score created to reduce the effect of confounding factors related to the choice of the treatment.Results: Out of the 91 included patients (50.5% of men, median age 52.0 (IQR [36.5; 62.0]) years), 71 were on HD and 20 were on PD. The highest subscale score, for all participants, was the social support's one with a median of 83.3 (IQR [66.7; 100]), and the lowest one was the kidney disease burden with a median of 25.0 (IQR [0.00; 46.9]). The univariate analysis showed that the Physical Component Score (PCS), the cognitive function, and the dialysis staff encouragement were better in PD patients (p = 0.03, p = 0.04, and p = 0.007, respectively), while the multiple linear regression indicates that the PCS, the dialysis Staff encouragement, and the patient's satisfaction subscores decreased within patients on HD compared with those on PD (p = 0.01, p = 0.03, and p = 0.02, respectively) and that the burden of the kidney disease and the work status subscores increased within patients on HD against those on PD (p = 0.007 and p = 0.04, respectively). Conclusion:This study showed a significant difference between dialysis modalities in some sides of quality of life.

International audienceCalcium sulfoaluminate clinker is one of the most promising cements that would lower the greenhouse gas effect accompanying cement production. This article examines the effect of gypsum content on the dimensional stability of sulfoaluminate mortars. Mechanical properties as chemical evolution are studied. Our results show that the mortar with the greatest gypsum content expands without a decrease of its mechanical properties when it is cured in water. Two hypotheses about the mortars hydration are discussed to explain the differents macroscopic behaviours of the two mortars
