BACKGROUND There is a high incidence of opportunistic infection among HIV-1-infected patients with tuberculosis in Africa and, consequently, high mortality. We assessed the safety and efficacy of trimethoprim-sulphamethoxazole 800 mg/160 mg (co-trimoxazole) prophylaxis in prevention of such infections and in decrease of morbidity and mortality. METHODS(More)
BACKGROUND In sub-Saharan Africa, various bacterial diseases occur before pneumocystosis or toxoplasmosis in the course of HIV-1 infection, and are major causes of morbidity and mortality. We did a randomised, double blind, placebo-controlled clinical trial at community-health centres in Abidjan, Côte d'Ivoire, to assess the efficacy of(More)
BACKGROUND Zidovudine reduces the rate of vertical transmission of HIV in non-breastfed populations. We assessed the acceptability, tolerance, and 6-month efficacy of a short regimen of oral zidovudine in African populations practising breastfeeding. METHODS A randomised double-blind placebo-controlled trial was carried out in public clinics of Abidjan,(More)
The 'oscillations' which have been observed in the visual cortex of cats and monkeys in the case of moving targets are discussed in relation to a temporal coding based on the arrival times of spikes or bursts. A decoding process for this temporal coding is proposed in which neurons work in a correlator mode. In the case of motion analysis, periodic(More)
BACKGROUND Staphylococcus aureus, one of the most frequently isolated pathogens in both hospitals and the community, has been particularly efficient at developing resistance to antimicrobial agents. In developed countries, as methicillin-resistant S. aureus (MRSA) has prevailed and, furthermore, as S. aureus with reduced susceptibility to vancomycin has(More)
Of 237 children with acute gastroenteritis in Antananarivo, Madagascar, during May 2004-May 2005, 14 ( 6%) were infected with norovirus. Seasonality (November-December peak) was detected. Reverse transcription-PCR identified GII as the most common genogroup. GIs belonged to GI.1, GI.3, and GI.4. Noroviruses in Madagascar show extensive genetic diversity.
We report data regarding the molecular epidemiology of human astrovirus (HAstV) infections among children in Madagascar. In a 13-month study, 5 HAstV isolates were detected in fecal samples from 237 children (2.1%) by reverse transcription-PCR. Phylogenetic analysis showed the cocirculation of usual and unusual HAstVs.
The case report of two brothers who evidenced neurological disorders with peripheral nerve syndrome, pyramidal deficit and bulbar symptoms is described. The diagnosis of amyotrophic lateral sclerosis was assumed upon the association of these clinical features. Seven and nine years respectively after the beginning of the disease, an increase of the clinical(More)
