JOURNAL FREE ACCESSA study was made of biliary cancer cases treated during the six-year period from1984 through 1989 by nine hospitals affiliated with the Akita Prefectural Welfare Federation of Agriculutural Cooperatives.
The number of cases under study totals 307. The 5-year survival rate was 14.0%. Broken down by sex 155 were men and 152 women. By site, 105 cases originated in the gallbladder, 154 cases in the bile duct, 22 cases in the duodenal papilla, and 26 cases in unspecified regions. Patients in their 70s were the largest in number.
Symptoms in the early stages were jaundice (especially notable in the cases of bile duct cancer) and abdominal pain. Most of the patients visited the hospital within one month after the initial symptoms occurred.
The 5-year survival rate was 18.7% in the cases of gallbladder cancer and 43.1% in the cases of duodenal papilla cancer. None of the bile duct cancer patients have not survived for five years.
The 5-year survival rate of those who underwent curative surgery was 62.9% for gallbladder cancer cases and 48.2% for duodenal papilla cancer cases. The result of curative resected cases of bile duct cancer was poor. Even the 3-year survival rate was as low as 47.5%.View full abstractDownload PDF (1157K) -

JOURNAL FREE ACCESSStudying the causes of death among inhabitants in mountain villages located alongside the middle stream of the Tenryu River, and farming-fishing villages located along Tokyo Bay, we found that the death rate from lung cancer was high in the former, and that from stomach cancer was high in the latter. So, in those two districts, we carried out case-control studies about both kinds of cancer. Investigation was made into the dead cases from lung cancer, 84 male cases and 168 male controls, and the dead cases from stomach cancer, 83 male and 39 female cases and the same number of controls. We selected these controls, matching district, sex, age, and year of death, and studied occupation and smoking in lung cancer cases ; occupation, eating habits, kinds of food, drinking and smoking in stomach cancer cases. The odds ratio concerning to lung cancer was as low as 0.40 among people engaged in agriculture, forestry or fishery. But that was as high as 3.25 among people exposed to metal dust, and also as high as 3.10 among those exposed to wood dust. The multiplier effect could be suggested between smoking and metal or wood dust exposure. The odds ratio concerning to stomach cancer was as low as 0.69 among males engaged in agriculture, forestry or fishery. Regarding eating habits, ‘rapid eating’ was as high as 2.57 in males, 3.00 in females. Concerning the kinds of food, ‘salted fish’ was as high as 1.90 in males, and ‘white vegetables’ was as low as 0.36 in females. No assocciation was found between stomach cancer and smoking or drinking.View full abstractDownload PDF (1519K) -

JOURNAL FREE ACCESSDuring the twelve years from January 1978 to December 1989, a total of 1, 409 cases of gastric cancer were treated in the surgical department of Tsuchiura Kyodo Hospital, located in the southern agricultural district of Ibaraki Prefecture.
Observations on these cases revealed: 1) Cases of gastric cancer tend to decrease, 2) Results of surgical treatment are improving remarkably, in terms of the resection rate and five-year survival rate, and 3) Most of the patients who survived more than five years after surgery are in satisfactory conditions.
The main factor contributing to the improvement of the results of surgical treatment of gastric cancer was increased detections of cancer in relatively early stages through mass survey or total check-up in the asymptomatic stage.
The decline of the morbidity rate of gastric cancer is reported to be more prominent in younger generations. This fact and the aging of the population in our society, especially in rural areas, will increase the number of elderly gastric cancer patients.
The future of surgery of gastric cancer depends on how early we can detect cancer and treat elderly patients. For this purpose, mass survey and total check-up on older people will be the most effective means.View full abstractDownload PDF (895K) -
Establishment of Incident Reporting SystemMasami MIKURUBE1992 Volume 41 Issue 2 Pages 110-117

JOURNAL FREE ACCESSA survey has found that the incidence of agricultural accidents caused by machinery in Kanagawa Prefecture is 14.7 per 1, 000 persons. This rate is about three times higher than that of industrial labor accidents. During the past 20 years, those who were killed in agriculturalaccidents throughout the nation totaled 7, 605 persons, which comes to an average of 380 persons per annum. From the standpoint of rural medicine and agricultural policies, this situation cannot be ignored any longer. To improve the situation, more effective safety measures must be explored. At the same time we must start investigating into human factors that lead to the accidents. The question why humans behave in a manner that may cost their own life is posed to us as a challenging theme. It is the theme to be grappled with in earnest for prevention of accidents wherever persons work in factories or in the fields. After all, accident prevention hinges on how effectively human errors can be prevented. For this purpose, it is necessary to collect as many experiences of workers as possible who have escaped death and injury by a hair's breadth during farming, and analyze those incident reports into potential accident-causing factors. If a system utilizing the data thus obtained is established in rural communities, it will be possible to further reduce the incidence of agricultural accidents.View full abstractDownload PDF (1000K) -
