title: Mass gastric examinations of prisoners at Miyagi Prison in Japan.
abstract: Mass examinations of the stomach were carried out on 79 convicts over 40 years of age confined in the Miyagi Prison, Japan. Of the 79 subjects, 11.9% were found to need detailed examination of the stomach which disclosed gastric polyp in one case and scar from gastric ulceration in one. None was found to have carcinoma of the stomach. Complaints of symptoms were obviously more frequent with the convicts as compared with a control group. There was not, however, a significant depression in efficiency of this group examination by photofluorography, as compared with the usual gastric mass examination on general inhabitants.
