STUDY DESIGN This study analyzed computed tomographic scans, magnetic resonance images, and biopsies of the paravertebral muscles of patients with camptocormia and age-matched patients with lumbar interapophyseal osteoarthritis or lumbar vertebral stenosis. OBJECTIVES To define the muscular lesions and clarify their nature in this particular disorder. (More)
OBJECTIVE To test if interleukin-1beta (IL-1beta), IL-1 receptor antagonist (IL-1Ra), IL-4, or IL-10 gene polymorphisms could be used as markers of susceptibility or severity in rheumatoid arthritis (RA). METHODS The study included 108 patients with early RA followed up for 2 years and 128 healthy controls. From genomic DNA, 6 polymorphisms in genes for(More)
Social media based brand communities are communities initiated on the platform of social media. In this article, we explore whether brand communities based on social media (a special type of online brand communities) have positive effects on the main community elements and value creation practices in the communities as well as on brand trust and brand(More)
OBJECTIVE To study the regional distribution of bone mass and look for factors leading to bone loss in ankylosing spondylitis (AS). METHODS Thirty-nine patients, all men, aged 20 to 55 years and presenting with AS were studied. Four hundred sixteen gendarmes, all men aged 20 to 55 years, formed an age matched control population used to define standard(More)

Ce document compare l’état de santé des immigrants et leur utilisation des services de santé à ceux de la population d’origine canadienne à l’aide de données provenant de deux cycles (1985 et 1991) de l’Enquête sociale générale (ESG). Les résultats obtenus démontrent que l’état de santé des immigrants de même que leur utilisation des services de santé ne(More)
BACKGROUND The mechanism of osteoporosis with fracture secondary to mastocytosis is little known, and its treatment is poorly codified. METHODS Ten patients with a mean age of 52.5 years with systemic mastocytosis and osteoporotic fractures were treated with interferon alpha 1.5 million U 3 times per week, combined with monthly pamidronate infusions (1(More)
The structural basis of the antifracture efficacy of strontium ranelate and alendronate is incompletely understood. We compared the effects of strontium ranelate and alendronate on distal tibia microstructure over 2 years using HR-pQCT. In this pre-planned, interim, intention-to-treat analysis at 12 months, 88 osteoporotic postmenopausal women (mean age(More)
When examining radiographs of patients with Paget’s disease of bone (PD), we often observed calcification of the aorta and iliac or femoral arteries. The processes of extraosseous calcification or mineralization are very close to the mechanisms regulating mineralization of bone tissue. The aim of our study was to quantify the number, extent (length and(More)
OBJECTIVES Bent spine syndrome (BSS) is characterized by involuntary forward flexion of the trunk in the standing position but not in the recumbent position. We assessed the causes of BSS based on findings in 63 patients. METHODS We retrospectively reviewed the records of all patients with BSS evaluated at a teaching hospital in Toulouse, France, between(More)
Many questions remain with regard to the treatment of osteoporosis. The increase in bone mineral density due to bisphosphonates accounts for only a quarter of their antifracture action. The studies of bone mineral density equivalences that have validated certain modes of administration are therefore not relevant. No comparative study on the same patient(More)
