Spontaneous pneumomediastinum and dermatomyositis may be a not so rare association: report of a case and review of the literature.

One patient with dermatomyositis (DM) who developed spontaneous pneumomediastinum (SPnM) is described. A review of 15 previously reported cases shows that this is a complication of DM but not of polymyositis. It occurs in young patients with recent onset of disease characterized by cutaneous vasculopathy, and patients treated with immunosuppressive drugs have, in general, better outcomes.

The effect of intravenous zoledronic acid on glucocorticoid-induced multiple vertebral fractures in juvenile systemic lupus erythematosus.

Glucocorticoids are widely used in the treatment of lupus patients, and adverse effects, which include osteoporosis and associated fractures, are frequent. Treatment of osteoporosis of young patients should be effective and not harmful to bone growth and remodeling. Bisphosphonates are drugs that decrease the incidence of bone fractures, but their use in juvenile patients is still controversial because of their possible side effects on the growing skeleton.
