The mean annual rates of hospital admission for deliberate self-poisoning were calculated for Caucasian and Asian 12-15-year-olds between 1982 and 1990 as 2.31 and 2.47 per 1000 respectively. There was an excess of girls in each group.
A study of self-poisoning in 25 Asian and 25 Caucasian adolescents is presented. Cultural conflicts were the most important factors in the parasuicidal behaviour of Asian children, whereas a variety of factors accounted for the parasuicidal behaviour of Caucasians with a predominance of a disrupted family background. There was little difference in the type of poisoning and the degree of pre-planning between the two groups.

We report the colonic pathology of two surgical excisions and two autopsies from patients acutely infected by E. coli O157:H7. The right colon was most severely affected. Extreme edema, fibrin deposition, and hemorrhage in the submucosa was the most distinctive finding. All cases showed patchy mucosal ulceration, mucosal hemorrhage, neutrophil infiltration, and microvascular thrombi. Pseudomembranous lesions similar to those described in pseudomembranous colitis caused by Clostridium difficile were a minor feature. Advanced lesions displayed regenerative mucosal changes and heavy plasmacytic infiltration of submucosa. The colonic pathology may be due to bacterial verocytotoxin rather than to bacterial attachment-effacement or invasion.
