Optic neuropathy in a child with primary Sjögren's syndrome.

An eight-year-old girl developed optic neuritis followed by primary Sjögren's syndrome confirmed by a lip biopsy. Glucocorticoid therapy combined during six months with monthly intravenous pulse cyclophosphamide ensured resolution of the sicca syndrome but failed to improve the visual impairment. This is the second pediatric case of optic neuritis associated with primary Sjögren's syndrome, and the first pediatric case in which optic neuritis was the only neurologic manifestation.

[Symptomatic treatment of benign hypertrophy of the prostate. Comparative study of prazosin and serenoa repens]. / Tratamiento sintomático de la hipertrofia benigna de próstata. Estudio comparativo entre Prazosin y Serenoa repens.

Forty-five patients diagnosed as having BPH and clinically diagnosed micturition disorders were entered in a therapeutic protocol. Twenty-five patients received Prazosin and the remaining 20 patients were treated with Serenoa Repens for a period of 12 weeks. The symptomatology was assessed by flowmetry and the patients were questioned as to the irritative symptoms. It can be concluded from the study that Prazosin is slightly more effective in controlling the irritative symptoms produced by BPH.
