Development and Pilot Testing of the Cutaneous Lupus Screening Tool.

Importance: Patients with cutaneous lupus erythematosus (CLE) experience significant morbidity and poor quality of life. In the absence of a dermatologist's examination, no reliable tool exists to confirm whether a patient has CLE for use in epidemiologic studies.

Objective: To determine whether the Cutaneous Lupus Screening (CLUSE) tool can detect cases of CLE by measuring its performance in individuals with dermatologist-diagnosed CLE compared with individuals without CLE.

Dermatomyositis induced by anti-tumor necrosis factor in a patient with juvenile idiopathic arthritis.

Importance: Biologic therapies, including anti-tumor necrosis factor (TNF) agents, are increasingly used to treat a variety of autoimmune diseases. Paradoxically, these agents have been reported to induce some of the very diseases they were designed to treat, including dermatomyositis (DM). We describe the first case of anti-TNF-associated DM without muscle involvement presenting in an adult patient with a history of arthritis since childhood.
