There is a disturbing inaccuracy, mostly observed to be overdiagnosis, in the diagnosis of FM by referring physicians. This finding may help explain the current high reported rates of FM and caution physicians to consider other diagnostic possibilities when addressing diffuse musculoskeletal pain.
BackgroundThe presence of a fragility fracture is a major risk factor for osteoporosis, and should be an indicator for osteoporosis diagnosis and therapy. However, the extent to which patients who fracture are assessed and treated for osteoporosis is not clear.MethodsWe performed a review of the literature to identify the practice patterns in the diagnosis and treatment of osteoporosis in adults over the age of 40 who experience a fragility fracture in Canada. Searches were performed in MEDLINE (1966 to January 2, 2003) and CINAHL (1982 to February 1, 2003) databases.ResultsThere is evidence of a care gap between the occurrence of a fragility fracture and the diagnosis and treatment of osteoporosis in Canada. The proportion of individuals with a fragility fracture who received an osteoporosis diagnostic test or physician diagnosis ranged from 1.7% to 50%. Therapies such as hormone replacement therapy, bisphosphonates or calcitonin were being prescribed to 5.2% to 37.5% of patients. Calcium and vitamin D supplement intake was variable, and ranged between 2.8% to 61.6% of patients.ConclusionMany Canadians who experience fragility fracture are not receiving osteoporosis management for the prevention of future fractures.
Our results suggest that osteophytes may be more prevalent in this population than radiographic data suggests due to the limitations of two-dimensional imaging. Meniscal degeneration or tears, a risk factor for knee osteoarthritis, are highly prevalent in asymptomatic individuals with the medial anterior and posterior horns being the most commonly affected regions.
Therapies for osteoporosis must be taken for at least 1 year to be effective. The purpose of this study was to determine the difference in adherence to etidronate, alendronate and hormone replacement therapy in a group of patients seen at our tertiary care centres. The Canadian Database of Osteoporosis and Osteopenia (CANDOO), a prospective observational database designed to capture clinical data, was searched for patients who started therapy following entry into CANDOO. There were 1196 initiating etidronate, 477 alendronate and 294 hormone replacement therapy women and men aged (mean, SD) 65.8 (8.7) years in the study. A Cox proportional hazards regression model was used to assess differences between treatment groups in the time to discontinuation of therapy. Several potential covariates such as anthropometry, medications, illnesses, fractures and lifestyle factors were entered into the model. A forward selection technique was used to generate the final model. Hazard ratios and 95% confidence intervals (CI) were calculated. Adjusted results indicated that alendronate-treated patients were more likely to discontinue therapy as compared with etidronate-treated patients (1.404; 95% CI: 1.150, 1.714). After 1 year, 90.3% of patients were still taking etidronate compared with 77.6% for alendronate. No statistically significant differences were found between hormone replacement therapy and etidronate users (0.971; 95% CI: 0.862, 1.093) and hormone replacement therapy and alendronate users (0.824; 95% CI: 0.624, 1.088) after controlling for potential covariates. After 1 year, 80.1% of patients were still taking hormone replacement therapy, which decreased to 44.5% after 6 years. Increasing age and presence of incident non-vertebral fractures were found to be independent predictors of adherence. In conclusion, alendronate users were more likely to discontinue therapy than etidronate users over the follow-up period. Potential barriers to long-term patient adherence to osteoporosis therapies need to be evaluated.
Hip fractures are an important cause of morbidity and mortality in the elderly. Hip protectors are padded undergarments designed to decrease the impact of a fall on the hip. We systematically reviewed randomized controlled trials of hip protectors to determine if they reduce hip fractures in the elderly. Analyses were pooled according to participant residence--community or institutional (the latter, included nursing homes, residential group homes or seniors' hostels). We included individually randomized and statistically adjusted cluster randomized trials. Seven trials of 12- to 28-month duration were included. The Safehip brand of hip protector was used in most studies. Compliance rates in the treatment groups varied from 31 to 68%. In four trials including a total of 5,696 community-dwelling seniors, the hip fracture rates in control groups ranged from 1.1 to 7.4%, and the pooled risk difference with hip protector allocation was 0% [95% confidence intervals (CI), -1%, +1%), with a relative risk of 1.07 (0.81, 1.42). In three trials including 1,188 institutionalized elderly participants, hip fracture rates in the control groups varied from 8 to 19.4%, and the pooled risk difference for sustaining one or more hip fractures with hip protector allocation was -3.7% (95% CI, -7.4%, 0.1%), with a relative risk of 0.56 (0.31, 1.01) (with statistically significant heterogeneity of treatment effect). In a post-hoc subgroup analysis of two trials comprised of exclusively nursing home residents, the risk difference with hip protector allocation was -4.4% (-8.09, -0.76) with a relative risk of 0.50 (0.28, 0.91) (n=1,014). Thus, there is little evidence to support the use of hip protectors outside the nursing home setting. The potential benefit of hip protectors in reducing hip fractures in nursing home residents requires further confirmation.
Background: The clinical use of minimum joint space width (mJSW) and cartilage volume and thickness has been limited to the longitudinal measurement of disease progression (i.e. change over time) rather than the diagnosis of OA in which values are compared to a standard. This is primarily due to lack of establishment of normative values of joint space width and cartilage morphometry as has been done with bone density values in diagnosing osteoporosis. Thus, the purpose of this pilot study is to estimate reference values of medial joint space width and cartilage morphometry in healthy individuals of all ages using standard radiography and peripheral magnetic resonance imaging.
A 42-year-old male presented with right-sided weakness, dysphasia and seizures while climbing the French Alps at an approximate altitude of 3,000 m. Imaging studies were consistent with superior sagittal sinus thrombosis with hemorrhage. Laboratory testing for thrombophilic states, 18 days after presentation at our hospital, showed a low protein C level (0.32 U/ml, normal 0.80–1.60 U/ml). A family member was also found to have protein C deficiency without a history of thrombosis. The patient gradually improved and was discharged on warfarin and valproic acid. This is the first reported case of cerebral venous thrombosis in a patient with congenital protein C deficiency who ascended to high altitude. We postulate that the ascent to high altitude represented an additional prothrombotic risk factor to the congenital protein C deficiency leading to cerebral thrombosis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
