Despite much evidence showing racial disparities in the use of surgical procedures, it is unknown whether ethnicity affects perception of surgical risk. ⋯ Patient ethnicity is an important factor to consider in understanding a patient's perception of risk in joint replacement surgery.

Treatment with tumor necrosis factor (TNF) antagonists in patients with rheumatic diseases has been associated with increased rates of tuberculosis due to reactivation of latent Mycobacterium tuberculosis (MTb) infection (LTBI). Diagnosis of LTBI is based mainly on the tuberculin skin test (TST), which has certain limitations. ⋯ Elispot assay is a useful test for diagnosis of LTBI in rheumatic patients scheduled for anti-TNF therapy and identification of patients with false-positive TST results due to previous BCG vaccination.

(1) To investigate dysfunction of hippocampus in patients with fibromyalgia syndrome (FM) using proton magnetic resonance spectroscopy (1H-MRS), and to compare these findings with healthy controls. (2) To correlate levels of metabolites obtained with aspects of cognition, depression, and sleep symptoms in the patient group. ⋯ The hippocampus was dysfunctional in patients with FM, as shown by lower NAA levels compared to controls, representing neuronal or axonal metabolic dysfunction. As the hippocampus plays crucial roles in maintenance of cognitive functions, sleep regulation, and pain perception, we suggest that metabolic dysfunction of hippocampus may be implicated in the appearance of these symptoms associated with this puzzling syndrome.

This prospective study examined circulating cytokines in patients with fibromyalgia (FM) over 6 months rather than at only one timepoint, and investigated correlations between serum cytokine concentrations and pain intensity in FM patients receiving multidisciplinary pain therapy. ⋯ Our results suggest that proinflammatory cytokines TNF-alpha and IL-8 are involved in FM, but they do not apparently provoke the pain of FM directly. Multidisciplinary pain therapy modified the cytokine profile in patients with FM during the observation period.

Practice Guideline
Canadian consensus practice guidelines for bisphosphonate associated osteonecrosis of the jaw.
Following publication of the first reports of osteonecrosis of the jaw (ONJ) in patients receiving bisphosphonates in 2003, a call for national multidisciplinary guidelines based upon a systematic review of the current evidence was made by the Canadian Association of Oral and Maxillofacial Surgeons (CAOMS) in association with national and international societies concerned with ONJ. The purpose of the guidelines is to provide recommendations regarding diagnosis, identification of at-risk patients, and prevention and management strategies, based on current evidence and consensus. These guidelines were developed for medical and dental practitioners as well as for oral pathologists and related specialists. ⋯ Our multidisciplinary guidelines, which provide a rational evidence-based approach to the diagnosis, prevention, and management of bisphosphonate-associated ONJ in Canada, are based on the best available published data and the opinion of national and international experts involved in the prevention and management of ONJ.
