RESUMO

In Mali, since 2007, artemether-lumefantrine has been the first choice against uncomplicated malaria. Despite its effectiveness, a rapid selection of markers of resistance to partner drugs has been documented. This work evaluated the treatment according to the World Health Organization's standard 28-day treatment method. The primary endpoint was the clinical and parasitological response corrected by a polymerase chain reaction. It was more than 99.9 percent, the proportion of patients with anemia significantly decrease compared to baseline (p < 0.001), and no serious events were recorded. Plasmodium falciparum remains sensitive to artemether-lumefantrine in Mali.

RESUMO

Galen aneurysmal malformation is a rare complex congenital vascular malformation of the brain, (less than 1% of intracranial arteriovenous malformations) characterized by pseudoaneurismal dilation of Galen's ampulla associated with one or several arteriovenous fistulas. In most cases, diagnosis is made in the neonatal or postnatal period, exceptionally in adulthood. We report the case of an 18-year male patient hospitalized for psychomotor retardation. Brain computed tomography (CT) scan using spontaneous contrast (A,B,C) showed voluminous isodense mass in the pineal region behind the third ventricle with peripheral calcifications, compatible with large vein of galen aneurysm. Its anteroposterior diameter was 8.5cm, its transverse diameter was 3cm in the axial plane (C) and its height was 3cm in the sagittal plane (G). Imaging objectified homogeneous contrast enhancement (D,E,F,G,H,I). The mass was associated with dilation of the superior sagittal sinus measured at 2.7cm (A,D), of transverse sinuses measured at 1.5cm to the right and at 1,1cm to the left (B,E). Multiple venous perianeurysmal derivations (I), hydrocephaly and small parenchymal cortical-subcortical calcifications were detected. Embolization can't be performed in Bamako, so the patient is waiting for transfer.

RESUMO

Rupture of spontaneous subcapsular hematoma of the liver is very rare and therefore it has been rarely described in the literature. It generally occurs among women with underlying liver disease or often, during pregnancy, in women with HELLP syndrome. We here report the case of a 60-year old man with no particular past medical history presenting with large subcapsular haematoma of the liver. He was admitted to the Emergency Department with moderate-intensity right hypochondre pain evolving over the last week, which was aggravated, two days before, by influenza-like illness associating cough, yellowish sputum and sweatings. Clinical examination showed abdominal tenderness on palpation of the right hypochondre and hypogastrium. The remainder of the clinic examination was normal. Laboratory tests showed hemoglobin level 7.8g/dl, MCV: 79.9, reticulocyte count 48.9. computed tomography (CT) scan showed voluminous subcapsular hematoma of the liver measuring 17cm in height, 14cm in cross-sectional diameter and 5cm in thickness and a hepatic nodule measuring 10mm (A) with hemoperitoine of great abundance without active bleeding (B). The patient underwent visceral surgery (laparotomy) with favorable postoperative outcome.

RESUMO

Kartagener's syndrome is a rare primitive ciliary dyskinesia (DCP) characterized by a clinical triad: sinusitis, bronchiectasis and complete or incomplete situs inversus. It is a rare congenital autosomal recessive disease. We report a case of Kartagener syndrome in an infertile couple with akinospermia detected using spermogram.

RESUMO

Introduction. L'hémosidérose du système nerveux central est une pathologie rare liée au dépôt d'hémosidérine à la surface du cerveau, des nerfs crâniens et de la moelle épinière secondaire à un saignement chronique. Nous rapportons un cas d'hémosidérose du système nerveux central chez une patiente jeune dans un tableau de méningite. A travers notre observation nous voulons décrire l'apport diagnostique de l'Imagerie par Resonnace Magnétique dans cette pathologie. Observation. Patiente de 39ans, sans antécédents particuliers, avait consulté au service des urgences pour des céphalées d'apparition brutale associées à des nausées. Le scanner cérébral objectivait un discret effacement des sillons corticaux et une sinusite sphénoïdale. L'Imagerie par Resonnace Magnétique cérébrale et médullaire objectivait un dépôt d'hémosidérine en hyposignal T2 Echo de gradient au niveau du cortex cérébral et de la moelle épinière. Le bilan étiologie du saignement chronique était négatif à l'angio-Imagerie par Resonnace Magnétique du polygone de Willis. La glycorachie était à 1,5g/l pour une glycémie à 5,6g/l (hypoglycorachie), la protéinorachie était à 2,43g/l sans bactériémie mais présence de 590 éléments dont 72% de lymphocytes et 27% de polynucléaires neutrophiles. Conclusion. L'Imagerie par Resonnace Magnétique est une technique indispensable au diagnostic de l'hémosidérose cérébro-méningée.

RESUMO

HIV genomic sequence variability has complicated efforts to generate an effective globally relevant vaccine. Regions of the viral genome conserved in sequence and across time may represent the "Achilles' heel" of HIV. In this study, highly conserved T-cell epitopes were selected using immunoinformatics tools combining HLA-A2 supertype binding predictions with relative global conservation. Analysis performed in 2002 on 10,803 HIV-1 sequences, and again in 2009, on 43,822 sequences, yielded 38 HLA-A2 epitopes. These epitopes were experimentally validated for HLA binding and immunogenicity with PBMCs from HIV-infected patients in Providence, Rhode Island, and/or Bamako, Mali. Thirty-five (92%) stimulated an IFNγ response in PBMCs from at least one subject. Eleven of fourteen peptides (79%) were confirmed as HLA-A2 epitopes in both locations. Validation of these HLA-A2 epitopes conserved across time, clades, and geography supports the hypothesis that such epitopes could provide effective coverage of virus diversity and would be appropriate for inclusion in a globally relevant HIV vaccine.

RESUMO

Objectifs : Etablir le profil épidémiologique des patients et répertorier les lésions retrouvées à la tomodensitométrie.Méthodes : Etude prospective descriptive sur une période de douze mois (de février 2015 à janvier 2016), portant sur des patients ayant bénéficiés d'une exploration tomodensitométrique pour traumatisme rachidien. Résultats : les traumatismes du rachis représentait 3,7% (n=100/2676) de l'ensemble des examens scanographiques effectués durant la période d'étude. Il y avait 83 % (n=83) d'hommes (sex-ratio de 4,88). La tranche d'âge 16 - 30 ans était la plus touchée avec 55% (n=55). Les accidents de la voie publique (AVP) représentaient 75% (n=75) des étiologies suivis de la chute de hauteur avec 16%(n=16). Les troubles neurologiques étaient le motif de réalisation de l'examen TDM dans 60%(n=60). Les atteintes rachidiennes étaient reparties comme suite : rachis cervical 43%(n=43), charnière cervico-dorsale 2%(n=2), rachis dorsal 22%(n=22), charnière dorso-lombaire 7%(n=7), rachis lombosacré 26%(n=26). Les lésions instables représentaient 76%(n=76) et les lésions stables 24%(n=24). Les fractures vertébrales représentaient 52%(n=52) suivies par les fractures luxations 46%(n=46).Conclusion : Le scanner est l'examen fondamental à réaliser dans le bilan initial des traumatismes rachidiens afin de préciser le caractère stable ou instable des lésions
