The characteristics of adult patients admitted for self-poisoning to an inner London district general hospital were examined during 1971/72 and 1983/84. The incidence of self-poisoning halved over the 12 years, from 326 to 178 per 100,000. Although no West Indians were admitted in the first period, they comprised 7% of such admissions 12 years later. The West Indian population in the catchment area remained constant at around 6%. Amongst all patients admitted for self-poisoning, there was a fall in the number of patients diagnosed as depressed, having a personality disorder or admitting to prior psychiatric care, but an increase in alcoholism. Paracetamol became more common as a drug used in self-poisoning and barbiturates were taken less often. Only one patient died in the series. These results should stimulate more soundly based epidemiological studies on ethnic variation in self-poisoning, and on self-injury in inner-city areas.

The successful isolation of C. pyloridis from human gastric mucosa has renewed interest in these bacteria and their role as a causative agent for gastritis, and possible causal relationship between chronic gastritis and peptic ulceration. To determine the incidence of C. pyloridis in gastric biopsies we studied 51 consecutive Brazilian patients with a wide range of alimentary disorders presenting for endoscopy. At least three biopsies were taken from each site: antrum, any ulcer or cancer. Microbiological and histological studies were performed to identify the bacteria. The organism was found in 40/51 (78%) of patients. These was a close correlation between culture (100%), Gram (90%) and Gimenez staining (80%) in identifying the bacteria. All C. pyloridis positive patients had histological evidence of antral chronic gastritis (active or quiescent) even if the endoscopic appearance looked normal. All peptic ulcer patients (n = 17) showed C. pyloridis in the antrum. In the duodenum the bacteria were mainly seen in gastric type of mucosa. Our findings support the hypothesis that C. pyloridis is etiologically related to gastritis and possibly peptic ulceration.
