Fifty-two patients with generalized Hodgkin''s disease were treated with a combination of mustine hydrochloride, vinblastine, procarbazine, and prednisolone. Complete remissions were obtained initially in six out of seven patients (86%) who had previously received no treatment, in 15 out of 19 (79%) who had had only radiotherapy in the past, and in 9 out of 26 (35%) who had previously been given chemotherapy with or without radiotherapy. Of these 30 patients in whom a complete remission was obtained 22 have been free of any symptoms or signs of disease for periods ranging from 4 to 22 months. The response to treatment was rapid, and toxicity was not a major problem, except in those who had previously been treated with cytotoxic drugs used continuously and not in courses. A comparative trial of radiotherapy and combination therapy in the treatment of Stage III Hodgkin''s disease is strongly recommended.  相似文献

Meningoencephalitis proved to be due to an amoeba (Naegleria) has been diagnosed in Great Britain for the first time. The first patient (a boy of 2) survived longer than any previously recorded cases, but in spite of early diagnosis and treatment he died 15 days after the onset of meningeal symptoms.Two other children who were exposed to the same possible source of infection (a warm, muddy puddle) had similar symptoms and developed mild meningitis. A naegleria was isolated from the cerebrospinal fluid of one of them. Both recovered after treatment with amphotericin.  相似文献

A double-blind controlled trial in 24 lepromatous leprosy patients in reaction showed that clofazimine (Lamprene) controlled symptoms of erythema nodosum leprosum reaction in lepromatous leprosy better than prednisolone. Clofazimine also appeared to be significantly superior in preventing recurrence once the reaction had been controlled. There was a statistically significant rise in serum albumin among inpatients on clofazimine as compared with patients on prednisolone, but no difference in terms of neurological status, bacterial index, morphological index, and renal functions. Red/black hyperpigmentation was seen among practically all patients on clofazimine. No other side-effects or deleterious systemic effects were observed.  相似文献
