Refractory Adult-onset Still's Disease Treated with a Combination of Methotrexate and Etanercept.

Background: Adult-onset Still's disease (AOSD) is a challenging diagnosis because of the variability in clinical presentation and lack of gold-standard diagnostic investigations. Even after diagnosis, the treatment is challenging, especially when the disease is refractory to first-line therapy. Multiple pharmacotherapeutic options exist for refractory AOSD, but treatment failures still occur.

Crystal arthritis. Gout and pseudogout in the geriatric patient.

Gout and pseudogout are inflammatory arthritides due to monosodium urate and calcium pyrophosphate dihydrate crystal formation. Both are prevalent among geriatric patients, and can present as acute mono- or oligoarticular disease, or as a chronic polyarthropathy resembling osteoarthritis or rheumatoid arthritis. Gout in the geriatric patient is a disease affecting women, commonly associated with diuretic usage, often involves the fingers, may be complicated by the development of masses of uric acid crystals (tophi) in soft tissues, and is frequently polyarticular.
