Lupus myocarditis: marked improvement in cardiac function after intravenous immunoglobulin therapy.
Intravenous immunoglobulin (IVIg) is emerging as the mainstay in the treatment of many autoimmune diseases, including systemic lupus erythematosus. IVIg has been found to be beneficial in myocarditis due to dermatomyositis/polymyositis, Kawasaki disease, and viral myocarditis in children. We report an 18-year-old man of active lupus with worsening cardiac systolic function who did not respond to pulse methylprednisolone and cyclophosphamide, but subsequently showed an improvement in his cardiac function after IVIg administration.

This study examines flexor digitorum tendons and A1 pulley in patients presenting trigger fingers using high-resolution ultrasonography (US), determines the accurate causes of trigger fingers, and analyzes the relationship between clinical data and US findings. As much as 50 trigger fingers of 41 patients were examined by high-resolution US, and the US findings were analyzed as tendon thickness, fibrillar echotexture, tendon margin, fluid collection, A1 pulley thickening, tendon sheath cyst, and metacarpophalageal (MCP) joint abnormalities. The affected fingers were compared with the asymptomatic opposite sides. ⋯ The patients with extension difficulty of the fingers had thicker flexor digitorum tendon than those without. The patients with locking fingers had more blurred margin of the tendon than those without. US can detect various lesions in clinical trigger fingers, and some US findings correlated with clinical findings.
