We present a 63-year-old man who developed multiple brain infarction after ingesting a 35% hydrogen peroxide solution. Neurologic examination revealed left hemiparesis, primarily affecting the lower limb, and mild weakness of the right lower limb. Gadolinium-enhanced MRI revealed patchy bilateral brain lesions. Oxygen gas embolization is the likely cause of the brain infarctions.

There is currently much concern over the morbidity and mortality of donors undergoing nephrectomy for living related renal transplants. Between April, 1970 and July, 1986, 247 cases of living related renal transplants were performed at the Second Department of Surgery, Kyoto Prefectural University of Medicine. The average age of the donors was 50.3 +/- 9.7 years, 81 per cent of the donors being parents of the recipients. Minor abnormalities which did not affect the donors suitability were found in 71 cases. Nephrectomies were performed extraperitoneally in all cases. Peri-operative complications, including wound complications in 13 cases, urinary infection in 12 cases and pulmonary complications and arrhythmia in 4 cases, were considered to be minor in nature. A variety of renal function tests, carried out two weeks after nephrectomy revealed normal levels, although they had become slightly worse than those estimated pre-operatively. Long-term sequelae in the follow-up period from 18 months to 16 years and 2 months, was studied on 124 donors who answered questionnaires. Currently, there are 5 late deaths, none of which are directly related to the nephrectomy. Of the 124 donors, 85.5 per cent stated that there had been no change in their physical states following surgery. Pain or a feeling of discomfort at the wound site was reported by 10 donors (8.1 per cent) and hypertension was observed only in 3 (2.4 per cent). No major complication directly related to the donor nephrectomy was found, except for one case of incisional hernia.(ABSTRACT TRUNCATED AT 250 WORDS)
