Une Bresilienne de 39 ans est adressee a l’hopital de Cayenne pour des cephalees, une confusion febrile et une alteration de l’etat general. Six mois plus tot, une infection par le VIH avait ete revelee (charge virale de 147 615 copies/ ml ; CD4 a 56/ mm3), au Bresil, par un tableau de tuberculose pleuro-pulmonaire non documentee. Elle suit depuis un traitement antiretroviral et une quadritherapie antituberculeuse, sans cotrimoxazole, traitement toujours en cours a son entree.

La pratique sportive doit être encouragée au cours de la grossesse, car les bénéfices sur la santé maternelle et fœtale sont importants en particulier en prévention du diabète gestationnel et du surpoids. La pratique est d’intensité au moins modérée en fonction du niveau antérieur et peut être poursuivie sans risque au cours de la grossesse physiologique, en l’absence de contre-indications. La reprise dans le post-partum sera progressive et individualisée.The sport should be encouraged during pregnancy because the health benefits are important, maternal and fetal especially in preventing gestational diabetes and overweight. Practice is at least moderate intensity depending on the previous level and can be continued safely during physiological pregnancy, in the absence of contraindications. Exercise in the postpartum period should increase gradually and should be individualized.

A model aimed at explaining prospective duration judgments in real life settings (as well as in the laboratory) is presented. The model is based on the assumption that situational meaning is continuously being extracted by humans’ perceptual and cognitive information processing systems. Time is one of the important dimensions of situational meaning. Based on the situational meaning, a value for Temporal Relevance is set. Temporal Relevance reflects the importance of temporal aspects for enabling adaptive behavior in a specific moment in time. When Temporal Relevance is above a certain threshold a prospective duration judgment process is evoked automatically. In addition, a search for relevant temporal information is taking place and its outcomes determine the level of Temporal Uncertainty which reflects the degree of knowledge one has regarding temporal aspects of the task to be performed. The levels of Temporal Relevance and Temporal Uncertainty determine the amount of attentional resources allocated for timing by the executive system. The merit of the model is in connecting timing processes with the ongoing general information processing stream. The model rests on findings in various domains which indicate that cognitive-relevance and self-relevance are powerful determinants of resource allocation policy. The feasibility of the model is demonstrated by analyzing various temporal phenomena. Suggestions for further empirical validation of the model are presented.

Exogenous lipod pneumonia is generally unrecognized clinically. Typical radiological patterns such as low (fat) attenuation in a condensation or a mass, associated with a positive history of oil inhalation or other source of lipoid consumption, may provide the diagnosis. Diagnosis is particularly important in the event of a chronic disease in order to avoid bronchoalveolar lavage or transthoracic, transbronchial or surgical lung biopsy. (C) 2010 Elsevier Masson SAS.

Le sarcome granulocytaire (SG) est une localisation extra-médullaire peu fréquente de la leucémie aiguë myéloïde (LAM). Ses modes de révélation sont variés. Nous rapportons six observations de SG cérébrales et spinales. Dans la majorité des cas, plusieurs diagnostics différentiels étaient évoqué, entraînant un retard ou une erreur diagnostique initiale ; l’apport de l’anatomopathologie et de l’immuno-histochimie se révélait décisif. Le sarcome granulocytaire est traité par chimiothérapie comme une LAM.Granulocytic sarcoma (GS) is a rare extramedullary tumor frequently associated with acute myeloblastic leukemia (AML). We report six cases of brain and spinal cord locations. In most cases, the diagnosis was delayed or initially missed. Pathology and immuno-histochemistry data identified the disease. GS is treated with chemotherapy, like AML.
