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.

[Primary Sjögren's syndrome with cutaneous vasculitis manifested as leg ulcerations].

Primary Sjögren's Syndrome (pSS) is an autoimmune disease with a large spectrum of clinical manifestations extending from an organ-specific involvement to a systemic process. The skin is affected quite commonly and the estimated frequency of inflammatory vascular lesions is from 20% to 30%. Two specific, clinically recognizable forms of cutaneous vasculitis predominate, palpable purpura and chronic urticaria, but erythema multiforme, erythema perstans, erythema nodosum, erithematous macules and subcutaneous nodules have also been described.
