OBJECTIVE The 1987 American College of Rheumatology (ACR; formerly the American Rheumatism Association) classification criteria for rheumatoid arthritis (RA) have been criticised for their lack of sensitivity in early disease. This work was undertaken to develop new classification criteria for RA. METHODS A joint working group from the ACR and the(More)
UNLABELLED A worldwide epidemic of hip fractures has been predicted. Time trends in BMD testing, bone-sparing medications and hip and wrist fractures in the province of Ontario, Canada, were examined. From 1996 to 2001, BMD testing and use of bone-sparing medications increased each year, whereas despite the aging of the population, wrist and hip fracture(More)
BACKGROUND Many patients who have undiagnosed osteoporosis and a recent fragility fracture present to fracture clinics in Canadian hospitals, where the focus of management is on fracture care. The rate of diagnosis and treatment of osteoporosis in this patient group is unknown. METHODS Patients who presented with fractures at sites consistent with(More)
A cross-sectional, community-based survey of a random sample of 1750 of 242,311 Medicare recipients was performed. The patients were at least sixty-five years old and had had a primary or revision knee replacement (either unilaterally or bilaterally) between 1985 and 1989. Three samples were surveyed separately: a national sample (to reflect the United(More)
Patients with dialysis-dependent renal failure are at increased risk for low-trauma fractures. However, the optimal means of identifying patients at high risk for fracture is not known. We assessed the association between fracture history and two tests of bone mineral density (dual x-ray absorptiometry [DEXA] and calcaneal ultrasound) among patients with(More)
Peak bone mass has been shown to be a significant predictor of risk for osteoporosis. Previous studies have demonstrated that skeletal mass accumulation is under strong genetic control, and efforts have been made to identify candidate loci. Determinants of peak bone mass also include diet, physical activity, hormonal status, and other clinical factors. The(More)
OBJECTIVE Remission in rheumatoid arthritis (RA) is an increasingly attainable goal, but there is no widely used definition of remission that is stringent but achievable and could be applied uniformly as an outcome measure in clinical trials. This work was undertaken to develop such a definition. METHODS A committee consisting of members of the American(More)
OBJECTIVE Compared with men and women without diabetes, individuals with type 2 diabetes have higher bone mineral density (BMD). However, they may still be at increased risk for hip fractures. Using population-based Ontario health care data, we compared the risk of hip fractures among men and women with and without diabetes. RESEARCH DESIGN AND METHODS(More)
OBJECTIVE To evaluate the measurement properties of a new osteoarthritis (OA) pain measure. METHODS The new tool, comprised of 12 questions on constant vs intermittent pain was administered by phone to 100 subjects aged 40+ years with hip or knee OA, followed by three global hip/knee questions, the Western Ontario and McMaster Universities (WOMAC) pain(More)
