Multicenter StudyQuantifying Temporomandibular Joint Synovitis in Children With Juvenile Idiopathic Arthritis.
Juvenile idiopathic arthritis (JIA) frequently affects the temporomandibular joints (TMJs) and is often undetected by history, examination, and plain imaging. Qualitative assessment of gadolinium-enhanced magnetic resonance images (MRIs) is currently the standard for diagnosis of TMJ synovitis associated with JIA. The purpose of this study is to apply a quantitative analysis of synovial enhancement to MRIs of patients with and without JIA to establish a disease threshold and sensitivity and specificity for the technique. ⋯ Calculating a ratio of pixel intensity between the TMJ synovium and the longus capitis muscle is a reliable way to quantify synovial enhancement. An ER of 1.55 differentiates normal TMJs from those affected by inflammatory arthritis.

Review Meta AnalysisPhysical Activity Interventions for Increasing Objectively Measured Physical Activity Levels in Patients With Chronic Musculoskeletal Pain: A Systematic Review.
To investigate whether physical activity interventions increase objectively measured physical activity levels of patients with chronic musculoskeletal pain (e.g., osteoarthritis, low back pain) compared to no/minimal intervention. ⋯ Our findings suggest that physical activity-based interventions may lead to little or no difference in objectively measured physical activity levels of patients with chronic musculoskeletal pain compared with no/minimal interventions. Given the number of registered trials, the pooled effect found in this review is likely to change once the results of these trials become available.
