Our Chilean colleagues, keenly sensitive to the prevalence of gastric cancer in that country, describe a patient with an antral ulcer which appeared to be highly suspicious of an early gastric carcinoma. Such was not the case. An editorial comment in this issue addresses the question of how radical resection might be avoided in these perplexing circumstances.

One hundred and sixteen patients with chronic intestinal amebiasis treated with diverse combinations of drugs and with a satisfactory follow-up are studied. Although success was obtained in 80 to 90 per cent of the cases in the different series, immediate results do not appear to be significantly superior to those obtained by the use of the antibiotic alone. Ideal controls should extend for periods of up to one year afterwards, but in our surroundings three to six months is enough because of poor sanitary measures and lack of cooperation from the patients. It is our opinion that amebiasis is a public health problem and that in our region it is useless to treat the individual patient unless the whole family group is treated and, more important, unless adequate sanitary measures are taken.
