Chronic Systemic Metal Ion Toxicity from Wear on a Revised Cobalt-chromium Trunnion.

Introduction: Metal toxicity secondary to corrosion and wear has been reviewed in the arthroplasty literature with evidence supporting dermatologic, neurologic, and cardiac involvement. This is the first report of a novel case with the occurrence of systemic pathology with only mildly elevated serum cobalt (Co) and chromium (Cr) levels due to trunnion wear in a metal-on-polyethylene articulation.

Case Report: A 45-year-old female who had undergone a revision total hip arthroplasty developed concerning dermatologic, neurologic, and cardiac symptoms.

Obesity Impacts Swelling of Ankle and Foot Joints in Early Rheumatoid Arthritis Patients.

Objective: The evaluation of disease activity in obese rheumatoid arthritis (RA) patients presents challenges particularly in the clinical assessment of swollen joints. This study examines the effect of obesity on the American College of Rheumatology (ACR) core set measures used in assessing RA disease activity with specific focus on the swollen joint count (SJC).

Methods: We examined a cross-sectional cohort of 323 early seropositive RA patients (symptom duration ≤15 months).

Contagious weakness in an elderly couple with neurologic emergencies.

We present an unusual neurologic emergency in an elderly male patient. Given his presentation and risk factors, we presumed the initial symptoms to be secondary to a cerebrovascular accident. As the case evolved, however, it became apparent that a more unusual pathology was present.
