Pneumonia due to Pneumocystis jirovecii (PCP) is a frequent infection among HIV-positive or other immunocompromised patients. In the past several years, PCR on pulmonary samples has become an essential element for the laboratory diagnosis of PCP. Nevertheless, very few comparative studies of available PCR assays have been published. In this work, we(More)
IMPORTANCE Infective endocarditis (IE) is a rare disease with poor prognosis. When IE is suspected, skin examination is mandatory to look for a portal of entry and classic skin lesions to help diagnose and manage the condition. OBJECTIVES To describe the prevalence of and factors associated with dermatological manifestations in patients with definite IE.(More)
Non-iatrogenic spondylodiscitis caused by anaerobic bacteria remains exceptional. We describe 2 cases of spondylodiscitis with epidural abscess due to Bacteroides fragilis, 1 after colonoscopy with biopsy and 1 in a cirrhotic patient. The clinical and imaging findings were not discriminant relative to other pyogenic spondylodiscitis. One should consider B.(More)
Anti-TNFalpha strategies can result in significant clinical benefits in rheumatoid arthritis (RA), but with an increased rate of opportunistic infections. Visceral leishmaniasis (VL) is a severe disease that can develop in immunocompromised hosts, principally in HIV patients. VL in RA patients treated with TNFalpha antagonists is an extremely rare event,(More)
Staphylococcus caprae has been recently classified as a human pathogen, but the incidence of S. caprae in human bone and joint infections (BJIs) is under-reported. In this study, we report 25 cases of S. caprae BJI, and we review the 31 cases published in the literature. Molecular techniques and matrix-assisted laser desorption ionization time-of-flight(More)
There is evidence for the interest of 18F-fluoro-deoxyglucose positron emission tomography with computed tomography (18F-FDG-PET/CT) in fever of unknown origin (FUO) clinical investigation. However, little and conflicting data exist about its place in the investigation procedure. The aim of this work was to evaluate the clinical value of 18F-FDG-PET/CT in(More)
The genetic diversity of HIV-1 strains in Chad was documented with a total of 107 samples from patients attending the general hospital in N'Djamena, the capital city of Chad. The genetic subtypes were identified in the V3-V5 env and p24 gag regions by sequence and phylogenetic tree analyses. Of the 107 strains, 78 had the same subtype/CRF designation(More)
Anti-tumor necrosis factor-a (anti-TNF-a) therapy strategies result in significant clinical benefits in patients with rheumatoid arthritis, but with an increased rate of serious infectious diseases. We describe a patient receiving infliximab who developed a primary cutaneous Nocardia otitidiscaviarum infection after a skin injury.
