 Abstract

- Asbestos exposure may cause asbestosis, pleural plaques and benign pleural disease, and may give a predisposition to malignant mesothelioma in occupationally exposed workers. This case report describes a 50-year-old man, dying from histologically confirmed, diffuse, malignant mesothelioma after asbestos exposure. As a young man, he had been exposed at the workplace to crocidolite for 2 years, but he had no other known history of occupational or environmental asbestos exposure. The patient presented with chest pain and general weakness. Computed tomography showed bilateral irregular pleural thickening along both lower lateral chest walls and a low attenuating mass in the anterior portion of the left lobe. Pathological examinations revealed that it was an epithelial type with tubulopapillary structures and it tested immunohistochemically positive for antibodies against cytokeratin, calretinin and vimentin. The patient was started on chemotherapy but he died to the disease at ten months after the first onset of the symptoms. Mesothelioma is a rare neoplasm in the general population. Nevertheless, the importance of close medical surveillance of the high-risk population is emphasized, because of increased asbestos exposure.

- OBJECTS: Residents are exposed to various hazards and harassed by sleep deficiency due to overwork. This study was performed to outline the health condition of residents and develop the ways of improving it.
METHODS
A questionnaire was distributed to 881 army doctors who enrolled at the Korea Third Military Academy and The Armed Force Health Service School in 2000 with the exception of medical doctors who joined the armed service without going through intern and resident periods , dental and oriental medical doctors. 784 (89.0%) of the 881 questionnaires were returned of which 704 cases (79.9%). This should actually be 89.0% were regarded for analyses as being reliable data.
RESULTS
More than 20% of residents were exposed to radiation, laser, disinfectants, anesthetic gas, and anticancer drugs during their training periods with preventive measures for each of these hazards taken in about 10% of the cases of the lesser hazards but in about 35% for the hazards from radiation and laser. 91.1% of residents had experience of needlestick injuries during their training periods with over 36.3% being exposed to patients with infection during that time. The cases contracting HBV and HCV diseases due to pricking are 2.3 and 0.6% respectively. The average number of night duties per month during a one-year resident's period was about 19. The average sleeping time on duty during a one-year residents was less than 4 hours .28.4% of respondents were not satisfied with their occupation, 96.5% felt tired from overwork and 69.5% wanted to change their occupation to another that would pay the same salary.
CONCLUSION
Residents are exposed to harmful physical , chemical and biological factors, but the preventive care seldom undertaken. In addition, their overwork brings about lack of sleep which causes them problems when giving medical treatment to patients during their training periods. Despite the resident's interest in an occupation as a doctor, many intend to select other occupations if they can receive the same salary. According to the above results, preventative systems and measures should be prepared with environmental improvements for residents, and proper rewards for their overwork should be accomplished.
