Staphylococcus spp. causes more than half of all osteoarticular infections of native structures or implanted material. The ability of Staphylococcus spp. to persist within infected bone tissue and to produce a bacterial biofilm, most notably in infections of implanted material, can lead to treatment failures and microbiological relapses. Rifampin is a(More)
In a prospective randomised trial of calcifying tendinitis of the rotator cuff, we compared the efficacy of dual treatment sessions delivering 2500 extracorporeal shock waves at either high- or low-energy, via an electromagnetic generator under fluoroscopic guidance. Patients were eligible for the study if they had more than a three-month history of(More)
OBJECTIVES To update the evidence-based position statement published by the French National Authority for Health (HAS) in 2006 regarding the pharmacological treatment of postmenopausal osteoporosis, under the auspices of the French Society for Rheumatology and Groupe de Recherche et d'Information sur les Ostéoporoses (GRIO), and with the participation of(More)
Genetic hemochromatosis (GH) is an iron overload disorder mainly due to the C282Y mutation of the HFE gene. The possibility of bone involvement was only recently recognized. The aims of this study were to assess bone mineral density (BMD) and bone remodeling in men with GH, and to examine the influence of iron overload. Thirty-eight men (mean age 47.2+/-9.4(More)
UNLABELLED In order to understand mechanisms involved in osteoporosis observed during iron overload diseases, we analyzed the impact of iron on a human osteoblast-like cell line. Iron exposure decreases osteoblast phenotype. HHIPL-2 is an iron-modulated gene which could contribute to these alterations. Our results suggest osteoblast impairment in(More)
OBJECTIVE To determine whether spinal magnetic resonance imaging performed one month into anti-microbial therapy for pyogenic discitis demonstrated changes of value for predicting outcomes and making therapeutic decisions. METHODS Prospective study of 16 patients with discitis. A physical evaluation, laboratory tests for inflammation, plain radiographs(More)
Although fractures involving the wrist, spine, and proximal femur are known to be strongly associated with osteoporosis, the underlying bone insufficiency often receives insufficient diagnostic and therapeutic attention. Osteoporosis also increases the risk of fractures at other sites. Low-energy fractures in patients older than 50 years should lead to(More)
Osteoporosis may complicate iron overload diseases such as genetic hemochromatosis. However, molecular mechanisms involved in the iron-related osteoporosis remains poorly understood. Recent in vitro studies support a role of osteoblast impairment in iron-related osteoporosis. Our aim was to analyse the impact of excess iron in Hfe-/- mice on osteoblast(More)
OBJECTIVES Although the cause of Sjögren's syndrome remains unknown, many arguments suggest a role for both environmental and genetic factors. An association with HLA molecules has been established. Other genes on the short arm of chromosome 6 may be involved, most notably the TNF gene, which may be pivotal in the development of the epithelial lesions. (More)
Hemochromatosis is a known cause of osteoporosis in which the pathophysiology of bone loss is largely unknown and the role of iron remains questionable. We have investigated the effects of iron on the growth of hydroxyapatite crystals in vitro on carboxymethylated poly(2-hydroxyethyl methacrylate) pellets. This noncellular and enzyme-independent model(More)
