Case ReportsDevelopment of interstitial pneumonia in a rheumatoid arthritis patient treated with infliximab, an anti-tumor necrosis factor alpha-neutralizing antibody.
Infliximab, an anti-tumor necrosis factor (TNF)-alpha antibody, was introduced to a 66-year-old woman with methotrexate (MTX)-resistant rheumatoid arthritis (RA). Although the TNF-blocking therapy was successful, she developed noninfectious interstitial pneumonia (IP) after a second infusion of infliximab. ⋯ Keeping a sharp lookout on IP development during this period is crucial to the success of infliximab treatment. After MTX discontinuation and steroid pulse therapy, our patient made a dramatic recovery from IP.

Based on the prevalence of musculoskeletal pain in the context of interference with daily activities (IDA) and treatment for musculoskeletal disorders in the study population (n = 3188), we estimated the prevalence and years lived with disability (YLD) of musculoskeletal pain in Japan. The total of 42,287 thousand (41.2%) of Japanese adult people was estimated to suffer from musculoskeletal pain. Among them, 9127 thousand was estimated to interfere with daily activities due to the pain. ⋯ One-way sensitivity analysis showed that the YLD of musculoskeletal pain might increase to 4,421,844.0 (4305.2 per 100,000) with the increased disability weight for Pain without IDA of 0.1, while they might inversely decrease to 1,018,875.0 (992.0 per 100,000) with the increased treatment rate in Pain with IDA of 100%. Musculoskeletal pain imposes a substantial burden on the Japanese adult population. To allow the population to keep their health-related quality of life, health professionals should pay more attention to musculoskeletal pain and make positive efforts to improve prevention and control of musculoskeletal pain.

Discovertebral lesion in ankylosing spondylitis: differential diagnosis with discitis by magnetic resonance imaging.
Abstract Ankylosing spondylitis (AS) is occasionally accompanied by erosive changes in the vertebral endplate at one or more restricted levels (Andersson lesions). The radiographic findings of this lesion are similar to those of bacterial discitis, and a differential diagnosis between them is often difficult. These diseases must be diagnosed correctly because they require different treatments. ⋯ All these three cases developed Andersson lesions in the earlier phase of the AS, and differentiating the lesions from bacterial discitis was difficult. The details of these three cases are reviewed, and the importance of differentiating between Andersson lesions and bacterial discitis is discussed. Plain radiographs showed no clear difference between these conditions, but magnetic resonance imaging (MRI) was found to be more efficient.
