The patient was a 67-year-old man who vomitted blood during therapy while hospitalized due to an asthma attack. He underwent a gastric examination, which detected a submucosal tumor on the greater curvature of the gastric antrum and gastric cancer on the lesser curvature. This tumor was diagnosed as a glomus tumor by postoperative pathological examination. In Japan, glomus tumors of stomach have been reported in 50 cases including our case. The mean age of patients was 48 years (23 to 74). Nineteen patients were male and 31 female. The main symptom was upper abdominal pain. The tumors developed in the submucosal layer of the greater curvature in the antrum and the mean size was 2.8cm. A Angiography revealed hypervascularization and endoscopic ultrasonography showed spheroid tumors localized in the muscle layer. Preoperative histological diagnoses were often difficult. Two cases including our patient were associated with gastric cancer.
To evaluate the risk factors of cerebral infarction, a case-control study was conducted in rural areas of Okayama prefecture that are rapidly urbanizing. The results of an interview focusing on psychological stress and stress response scales, questionnaires on life styles and mass health examinations were analyzed by conditional logistic regression methods. The results were as follows: 1. Psychological stress, smoking, hypo-HDL-cholesterolemia, hypercholesterolemia and high grade preference for fat were identified as new risk factors of cerebral infarction in rural areas in addition to known risk factors such as hypertension, glucose intolerance, atrial fibrillation and high consumption of rice and salt. 2. High consumption of salt, diastolic high blood pressure and hypo-HDL-cholesterolemia were strongly related to an increased risk of cerebral infarction. 3. The age at onset of cerebral infaction was noted to be increased becuse the odds ratios were high for systolic blood pressure as well as diastolic blood pressure. 4. Targets for strategies of preventive medicine for cerebral infarction are needed giving attention to the risk factors sucb as increased psychological stress, smoking that reflect modern life style chages in rural areas.
