목적: 제약회사에서 직업상 천식의 유병 규모를 파악하고 작업공정에 대한 작업환경 측정을 통해 제약회사의 약제 분말에 대한 노출수준을 평가하고자 하였다. 방법: 제약회사에서 약제 분말에 노출되는 근로자를 대상으로 천식을 선별하기 위하여 설문조사 및 진찰, 혈액검사, 폐기능 검사 그리고 피부단자시험을 실시하였고, 각 부서별 공정에 따라서 총분진과 항생제 또는 효소제 분말에 대한 작업환경 측정을 실시하였다. 직업상 천식이 의심되는 근로자에 대하여 기관지과민성에 대한 검사(메타콜린을 이용한 비특이 기관지유발시험)와 약제 분말 기관지유발시험을 실시하여 확진하였다. 결과: 설문조사 및 진찰에서 작업 관련 천식 증상이 있는 근로자는 11명(34.4%)이었고, 약제 분말을 이용한 피부단자시험에서 1+ 이상 반응을 보인 근로자 10명(31.2%)이었다. 비특이 기관지유발시험 결과 8명(25.0%)이 양성(PC20 ≤16 mg/ml)이었다. 약제 분말 기관지유발시험을 통해 직업상 천식으로 확진된 근로자는 5명(15.6%)이었다. 작업환경 측정에서 원료를 충진하거나 투입하는 작업 그리고 정립작업에서 약제 분말에 대한 노출이 많았다. 결론: 제약회사에서 직업상 천식은 주로 제조공정 중 약제 분말에 노출된 근로자에서 발생하여, 증상 및 직업성 천식의 유병률이 높았다. 따라서 원료를 충진 또는 투입하는 작업과 정립작업 등 제조과적에서 약제 분말 노출을 줄이기 위한 세심한 주의가 필요하여, 약제 분말을 취급하는 근로자에 대해서는 천식 증상 조사뿐 아니라 정기적으로 피부단자시험, 비특이 기관지유발시험 등을 실시하여야 할 것이다. Objectives: After the investigation of one worker with occupational asthma, we surveyed the preva- lence of occupational asthma and the exposure level of pharmaceutical dust of 32 workers in a pharmaceutical company. Methods: Thirty-two of the 90 employees participated in the survey which consisted of questionnaire, blood sampling, spirometry and skin prick tests with 8 common allergens as well as 9 antibiotics and 2 enzymes. Various indices of the working environment were also measured. Subjects who had a symptom suggestive of work-related asthma or positive skin prick test were further investigated by PC20 methacholine. Nine subjects who had a PC20 result of 16 mg/ml or less (n=7) or had work-related symptoms and positive skin prick test (n=2) were referred to undergo a specific bronchial provocation test to phar- maceutical dust in an academic allergic disease center. Results: Eleven of 32 workers (34.4%) had a work-related symptom suggestive of occupational asthma. Ten (31.2%) showed positive skin prick test. 8 (25.0%) had a PC20 result of 16 mg/ml or less (indicative of significant bronchial hyperresponsiveness), and 5 (15.6%) had a positive result on the specific bronchial provocation test. Exposure levels of stuffing, input of raw materials and screening process were relatively high. Conclusions: This survey showed that pharmaceutical workers have an increased risk of occupational asthma. Although pharmaceutical factories maintain a relatively good working environment, careful control of respiratory tract exposures, especially during stuffing, input or raw materials and screening process, is important to prevent occupational asthma. Pharmaceutical workers need to undergo regular skin prick and methacholine bronchial provocation tests, as well as asthmatic symptom survey, to ensure the early detection and prevention of occupational asthma.

Objectives : Pneumoconisis and noise-induced hearing loss (NIHL) have been reported as main occupational diseases by the Special Health Examination. The Industrial Accident Compensation Insurance has reported various work-related diseases, however, these two diseases occupied almost a half of compensated cases. Therefore, it was not well known about the status of occupational diseases other than pneumoconiosis, NIHL, and cardio-cerebrovascular accident (CVA). This study was conducted to analyze claimed cases as an occupational disease, that was requested to the Korea Industrial Safety and Health Agency (KOSHA). Methods : The local office of the Korea Labor Welfare Corporation (KLWC) has asked the KOSHA for confirmation of claimed cases as an occupational disease. We analyzed 379 cases requested from KLWC, the Ministry of Labor, employers, unions and occupational health agencies from 1992 to 1999. Results : Male was 80.7 % of the requested cases. Their mean age was 42 years old and 75.5 % of them were more than 35 years old. The requested cases were increased rapidly from 25 cases in 1992 to 108 cases in 1999 and the accept rate was 50.7 %. The majority of requested cases were respiratory diseases(22.4%), cancers(18.5%), Neuropsychiatric problems(14.5%), and musculoskeletal problems(13.5%). The accept rate was high in reproductive, respiratory, musculoskeletal and digestive disorders and low in neuropsychiatric, renal and otologic problems and occupational cancers. 73.6% of them were caused by chemical agents, especially 28.5 % were by organic solvents. 67% of them were clinically confirmed at university hospitals. A half of the cases were from KyongIn area, even the request came from the whole country. Conclusions : A claim was common in workers whose age was over 35 years old and exposure history was over 10 years. The respiratory diseases and neuropsychiatric disorders were still main problems in occupational health and occupational cancers was increasing even though its accept rate was not high yet.

N/A Diverticular disease of the colon is extremely common in developed Western nations, in which the most common site of diverticula is the sigmoid. Its prevalence increases with age and complications occur not rarely. In Asia and Africa, however, lower overall prevalence, higher frequency in right-side colon than left-side and rarer complications are observed. Therefore, we analyzed the prevalence, location and the number of divericula with double-contrast colon studies, and clinical manifestations and complications in 12,599 patients in Seoul National University Hospital from January 1988 to December 1991. Overall prevalence of diverticular disease of the colon was 4.1%, mean age 53.8 year and the ratio of male to female was 2:1. Diverticula occurred 6 times more frequently in the right-side colon than left-side. The prevalence of diverticula in left-side colon increased with age. Mean number of diverticula was 4.9 and the cases with rnore than 11 diverticula belonged to aged group exclusively. The rnost common symptoms were abdominal discomfort and pain. Complications were diverticulitis (1.8%) and lower gastrointestinal hleeding (1%). These data suggest that the prevalence of diverticular disease of the colon is low in Korea compared with the prevalence in Western nations, but it is increasing these days. Right-side colon is the predominant site of colonic diverticula in Korea, but increase in frequency in left-side colon with age was observed. Complications were rare and could be managed with medical treatment.

Hepatic hemangioma is the most common benign tumor of the liver which presents typical angiographic features, and can be usually differentiated from other tumorous conditions by various radiographic methods including angiography. However a review of the literatures shows a few cases with normal angiogram. The causes of nonopacification on angiogram described in the literatures are small size, fibrosis of the tumor, and dilution phenomenon of injected dye. We report a case of hepatic hemangioma, which showed normal angiogram, because of blood supply from a feeding vessel branched from portal vein.

N/A We reviewed clinical records of 34 cases of primary tumors in the small intestine from 1986 to 1990. In total 34 cases, 26 cases were male and 8 cases were female. The mean age was 50.9 year. Benign tumors were 6 and malignant tumors were 28. The most common symptom of benign tumors was abdominl pain (83%) followed by anemia (50%) and intussusception (33%). The most common symptom of the malignant tumors was also abdominal pain (86%) followed by weight loss (50%), anemia (43%), constipation (43%), and palpable mass (39%). Leiomyoma was the most common benign tumor and adenocarcinoma was the most common malignant tumor. Adenocarcinomas occured predominatly in the duodenum and malignant lymphomas occured prednminantly in the ileum. In the duodenal tumors, the detectabilities of endoscopy and upper GI series were 79% and 77%, respectively. In the jejunal and the ileal tumors, the detectabilities of small bowel series were 50% and 71%, respectively and those of abdominal computed tomogram were 30% and 33%, respectively. The accuracy of preoperative diagnosis in pathology was 32% and only 65%. of patients could be diagnosed to have small intestinal tumors before surgery.

N/A We reviewed the total 291 procedures in 134 patients in whom esophageal dilatation or esophageal endoprosthesis insertion had been performed in Seoul National University Hospital from March 1987 to September 1990. Twelve cases(4.1%) of esophageal perforation developed. Eight cases of them were managed successfully only with medical treatment. Two cases were not followed up after self-discharge during medical treatement. One case was treated successfully with immediate surgical intervention and one case underwent delayed surgical repair two times because of the failure of initial medical treatment. There were 7 cases of esophageal perforation with pleural or peritoneal involvement. Five of them were managed successfully with medical treatment. Thus we recommended the medical management as the first choice of treatment in iatrogenic esophageal perforation even in the cases with pleural or peritoneal involvement except in some selected cases.
