Cavernomatose cĂ©rĂ©brale sporadique rĂ©vĂ©lĂ©e par une crise convulsive: Ă propos dâun cas
La cavernomatose cĂ©rĂ©brale est une pathologie rare pouvant ĂȘtre sporadique ou familiale autosomique dominante. Elle est caractĂ©risĂ©e par la prĂ©sence de cavernomes multiples du systĂšme nerveux central. Souvent asymptomatique, la pathologie peut se rĂ©vĂ©ler par des symptĂŽmes variĂ©s comme lâhĂ©morragie cĂ©rĂ©bro-mĂ©ningĂ©e, les cĂ©phalĂ©es ou lâĂ©pilepsie. Nous rapportons un cas de cavernomatose cĂ©rĂ©brale sporadique chez un patient de 55 ans sans antĂ©cĂ©dent pathologique particulier rĂ©vĂ©lĂ© par une crise dâĂ©pilepsie. A travers cette observation et une revue de la littĂ©rature, nous faisons le point sur les aspects cliniques et radiologiques (scanner et IRM) de cette pathologie

Profil épidémiologique de la rougeole au Mali de 2009 à 2018: Epidemiological profile of measles in Mali from 2009 to 2018
Introduction: La rougeole, maladie virale hautement contagieuse causeÌe par un Morbillivirus, reste un important probleÌeme de santeÌ publique dans de nombreux pays malgreÌ l'existence d'un vaccin efficace. La surveillance de la rougeole est l'un des aspects cleÌs de la lutte contre cette maladie. La preÌsente eÌtude avait pour objectif de deÌcrire la mortaliteÌ et la morbiditeÌ de la rougeole au Mali entre 2009 et 2018. MĂ©thodes: Il s'agissait d'eÌtude transversale descriptive. Les donneÌes de surveillance de la rougeole au Mali de 2009 aÌ 2018 ont eÌteÌ analyseÌes en personne, lieu et temps. RĂ©sultats: De 2009 aÌ 2018, le nombre de cas confirmeÌs de rougeole eÌtait de 6461 dont 29 deÌceÌs soit une leÌtaliteÌ de 0,45%. La confirmation des cas avait eÌteÌ faite par le laboratoire pour 2551 cas (39,48%), par lien eÌpideÌmiologique pour 3738 cas (57,85%) et cliniquement pour 172 cas (2,66%). Les enfants de moins de 5 ans repreÌsentaient 50,97% des cas et 75,86% des deÌceÌs. La majoriteÌ des cas (95,71 %) n'avaient jamais eÌteÌ vaccineÌs contre la rougeole. Les incidences les plus eÌleveÌes avaient eÌteÌ observeÌes en 2009 (22,65 pour 100 000 hbts) et 2010 (11,81 pour 100 000 hbts). Tombouctou, Gao et Mopti avaient enregistreÌs les plus grands nombres de cas en 2009 et Bamako, Koulikoro et Mopti en 2010. Conclusion: La majoriteÌ des cas et des deÌceÌs eÌtaient les enfants non vaccineÌs de moins de cinq ans. Un renforcement du programme eÌlargi de vaccination de routine, une riposte aux eÌpideÌemies et des strateÌegies de vaccination couvrant tout le pays sont neÌcessaires.
Introduction: Measles, a highly contagious viral disease caused by a Morbillivirus, remains an important public health problem in many countries despite the availability of an effective vaccine. Measles surveillance is one of the key aspects of measles control. The objective of this study was to describe measles mortality and morbidity in Mali between 2009 and 2018. Methods: This was a descriptive cross-sectional study. Measles surveillance data in Mali from 2009 to 2018 were analysed by person, place and time. Results: From 2009 to 2018, the number of confirmed measles cases was 6461 including 29 deaths, i.e. a case-fatality rate of 0.45%. Cases were confirmed by the laboratory for 2551 cases (39.48%), by epidemiological link for 3738 cases (57.85%) and clinically for 172 cases (2.66%). Children under 5 years of age represented 50.97% of cases and 75.86% of deaths. The majority of cases (95.71%) had never been vaccinated against measles. The highest incidences were observed in 2009 (22.65 per 100,000 inhabitants) and 2010 (11.81 per 100,000 inhabitants). Timbuktu, Gao and Mopti had the highest number of cases in 2009 and Bamako, Koulikoro and Mopti in 2010. Conclusion: The majority of cases and deaths were among unvaccinated children under five years of age. Strengthening of the routine expanded programme of immunisation, response to epidemics and nationwide immunisation strategies are needed
A novel de novo variant in the RUNX2 gene causes cleidocranial dysplasia in a Malian girl
Key Clinical Message Cleidocranial dysplasia (CCD) is a rare genetic skeletal disorder with only few cases reported in Africa, mostly based on clinical and radiological findings. We report the first case in Mali, caused by a novel de novo variant in the RUNX2 gene. Abstract Cleidocranial dysplasia (CCD) is a rare autosomal dominant skeletal dysplasia characterized by an aplastic/hypoplastic clavicles, patent sutures and fontanels, dental abnormalities and a variety of other skeletal changes. We report a novel de novo variant in the RUNX2 gene causing a severe phenotype of CCD in a Malian girl
Specificity of serological screening tests and reference laboratory tests to diagnose gambiense human African trypanosomiasis: a prospective clinical performance study
International audienceBackground Serological screening tests play a crucial role to diagnose gambiense human African trypanosomiasis (gHAT). Presently, they preselect individuals for microscopic confirmation, but in future âscreen and treatâ strategies they will identify individuals for treatment. Variability in reported specificities, the development of new rapid diagnostic tests (RDT) and the hypothesis that malaria infection may decrease RDT specificity led us to evaluate the specificity of 5 gHAT screening tests. Methods During active screening, venous blood samples from 1095 individuals from CĂŽte dâIvoire and Guinea were tested consecutively with commercial (CATT, HAT Sero- K -SeT, Abbott Bioline HAT 2.0) and prototype (DCN HAT RDT, HAT Sero- K -SeT 2.0) gHAT screening tests and with a malaria RDT. Individuals withââ„â1 positive gHAT screening test underwent microscopy and further immunological (trypanolysis with T.b. gambiense LiTat 1.3, 1.5 and 1.6; indirect ELISA/ T.b. gambiense ; T.b. gambiense inhibition ELISA with T.b. gambiense LiTat 1.3 and 1.5 VSG) and molecular reference laboratory tests (PCR TBRN3, 18S and TgsGP; SHERLOCK 18S Tids, 7SL Zoon , and TgsGP; Trypanozoon S 2 -RT-qPCR 18S2, 177T, GPI-PLC and TgsGP in multiplex ; RT-qPCR DT8, DT9 and TgsGP in multiplex). Microscopic trypanosome detection confirmed gHAT, while other individuals were considered gHAT free. Differences in fractions between groups were assessed by Chi square and differences in specificity between 2 tests on the same individuals by McNemar. Results One gHAT case was diagnosed. Overall test specificities ( n =â1094) were: CATT 98.9% (95% CI : 98.1â99.4%); HAT Sero- K -SeT 86.7% (95% CI : 84.5â88.5%); Bioline HAT 2.0 82.1% (95% CI : 79.7â84.2%); DCN HAT RDT 78.2% (95% CI : 75.7â80.6%); and HAT Sero- K -SeT 2.0 78.4% (95% CI : 75.9â80.8%). In malaria positives, gHAT screening tests appeared less specific, but the difference was significant only in Guinea for Abbott Bioline HAT 2.0 ( P =â0.03) and HAT Sero- K -Set 2.0 ( P =â0.0006). The specificities of immunological and molecular laboratory tests in gHAT seropositives were 98.7â100% ( n =â399) and 93.0â100% ( n =â302), respectively. Among 44 reference laboratory test positives, only the confirmed gHAT patient and one screening test seropositive combined immunological and molecular reference laboratory test positivity. Conclusions Although a minor effect of malaria cannot be excluded, gHAT RDT specificities are far below the 95% minimal specificity stipulated by the WHO target product profile for a simple diagnostic tool to identify individuals eligible for treatment. Unless specificity is improved, an RDT-based âscreen and treatâ strategy would result in massive overtreatment. In view of their inconsistent results, additional comparative evaluations of the diagnostic performance of reference laboratory tests are indicated for better identifying, among screening test positives, those at increased suspicion for gHAT
