Osteoarthritis (OA) of the knee is the most common form of arthritis. A positive association between obesity and several occupational factors and knee OA has been observed in previous studies in populations of different ethnicity. The aim of this study was to examine the relation between knee OA and body weight and occupational factors in a Moroccan sample(More)
UNLABELLED Ankylosing spondylitis (AS) is characterized by inflammation of the entheses and paravertebral structures, leading in time to bone formation at those sites. As well, vertebral bone loss is also a recognized feature of AS Objective: To calculate the prevalence and risk factors of osteoporosis and vertebral fractures in patients with AS. METHODS(More)
Bone mineral density (BMD) measurements are frequently performed repeatedly for each patient. Subsequent BMD measurements allow reproducibility to be assessed. Previous studies have suggested that reproducibility may be influenced by age and clinical status. The purpose of the study was to examine the reproducibility of BMD by dual energy X-ray(More)
BACKGROUND Diagnostic discordance for osteoporosis is the presence of different categories of T-scores in 2 skeletal sites of an individual patient, falling into 2 different diagnostic categories identified by the World Health Organization classification system. OBJECTIVES To evaluate the prevalence and risk factors for T-score discordance between spine(More)
The aim of this study was to test bone mineral density (BMD), trabecular bone score (TBS), and their combination, for detection of rheumatoid arthritis (RA) patients with vertebral fractures (VFs). One hundred eighty-five women aged 56.0 ± 13.5 yr, with RA since 15.5 ± 9.9 yr were studied. Lumbar spine, total hip, and femoral neck BMD were assessed by(More)
OBJECTIVE Studies of bone turnover in fibromyalgia (FM) have, to date, shown conflicting results. Although most patients with FM are women, only a few investigations have paid attention to the changes of sex hormones in FM. Moreover, FM is often viewed as a stress related disorder, and abnormalities of the hypothalamic-pituitary-adrenal (HPA) axis have been(More)
Introduction Measuring bone mineral density (BMD) is a widely accepted strategy for identifying subjects with an increased risk of fracture. However, because of limited availability of BMD technology in some communities and cost considerations, it has been proposed that BMD measurements be targeted to subjects with risk factors for osteoporosis. Recently,(More)
INTRODUCTION Vertebral fracture assessment (VFA) is a technology that can reliably and accurately diagnose vertebral fractures with greater patient convenience, less radiation exposure, and lower cost than standard spine radiography. OBJECTIVE To study prevalence and risk factors of vertebral fractures using VFA in healthy men. METHODS The study cohort(More)
Specific antagonists of tumour necrosis factor (TNF-alpha) have rapidly gained popularity for the treatment of rheumatoid arthritis and ankylosing spondylitis (AS). Reported side effects from these agents include drug-induced autoimmune disorders. The monoclonal antibody against TNF-alpha, infliximab, has been associated with induction of systemic lupus(More)
Vertebral fracture assessment (VFA) is a convenient tool for the diagnosis of vertebral fracture in RA. Optimal control of inflammation may be an effective means to protect against vertebral fractures. The aim of this case–control study was to assess the prevalence of vertebral fractures (VFs) in patients with RA using VFA technology. Consecutive women (N =(More)
