RESUMO
This is a report on the precision controlled gastric mass screenings conducted under the sponsorship of the Welfare Federation of Agricultural Cooperatives in Nagano Prefecture and the assessment test using some samples of radiographic stomach images.<BR>Physicians and x-ray technicians participated in the test and interpreted in their own ways the radiographs of 30 healthy cases and 20 cases of cancer of the stomach. Experienced physicians and technicians made better scores on the test than those less experienced in reading radiographs. Physicians read a little better that technicians in checkups of different parts regardless of years of experience, but the difference was not significant. In terms of FP and FN percentages (?), physicians scored 40.5% and 20.8% on the first tryout, and 34.0% and 29.0% on the second tryout.<BR>The 1988 mass screening found 67.4% of cancer in antral and angular areas and 23.8% on the lesser curvature side of the angular area.<BR>Grade 5 means that “No doubt about the existence of cancerous lesions.” In the 1983 screening, 25% of the grade 5 cases turned out to be nothing wrong upon close examination. The figure went down to 5.9% in the 1988.
RESUMO
Blessed with a mild climate and located conveniently, Shizuoka Prefecture is the nation's leading tea and orange growing center. It also produces rice, vegetables and melons in large quantities.<BR>This paper reports on the findings obtained in an investigation of the role of women in farming, their amount of work, and living and health conditions in the central part of Shizuoka Prefecture.<BR>For the sake of comparision, this region was divided into the three areas different from each other in production structure and living environment.<BR>The area in and around Shizuoka City, the capital of the prefecture was designated as Area A, where tea, orange and rice are principal products. Area B is a flat-land district where mixed farming is dominant and rice, tea and vegetables are grown. Area C is a hilly, wooded area. The major farm products are tea and mushrooms.<BR>More than 80% of women are engaged in farm work, and espeically in the tea-pricking season 90% work out in the terraced fields.<BR>It was found that about 3% of the women surveyed are suffering injuries caused by farm implements and machinery. More than 90% said they have engaged in the spraying of pesticides, and 8 to 19% of them said they had subjective symptoms of intoxication after spraying.<BR>The findings of medical examinations for anemia, cardiovascular disease, liver function, stomach cancer, uterine cancer and so on will be discussed in this report.
RESUMO
This is a review of the results of mass screenings for early detection of stomach diseases conducted during the past 10 years from 1971 to 1980 and similar disease prevention schemes undertaken by 25 prefectures in 1980. The materials we used are the statistics presented at the 1981 general meeting of the Japanese Association of Rural Medicine and the 1979 and 1980 survey findings on mass screenings prepared by the Japanese Society of Adult Disease Prevention.<BR>1. The number of people who receivea group stomach examination during a year increased from 128, 169 in 1971 to 274, 905 in 1980.<BR>2. Of the total number of persons who underwent stomach checkups during 1980, 16.0% were urged to get intensive medical examination.<BR>3. Those who actually got intensive exams accounted for 76.3% of those tho were required to receive such exams. This ratio varies greatly from 27.0% to 92.9% according to prefectures.<BR>4. Stomach cancer was found in 255 people. This represents 0.093% of the total number of the examinees and includes 113 persons with early gastric cancer (44.1% of the total stomach cancer cases). Among other diseases detected in the mass screenings are gastro-polyp (1, 151 cases, 0.42%), gastric ulcers (2, 301 cases, 0.84%) and duodenal ulcers (1, 285 cases, 0.47%). Altogether, 13, 730 or 4.99% of the total number of the examinees were found that they have ailments.<BR>5. The methods employed in mass screening, intensive medical examination, procedures after examination and follow-up study differ from prefecture to prefecture.<BR>So it is difficult to obtain the exact picture of health conditions of rural inhabitants from the data we used.
