The value of the computed tomography(CT) in the diagnosis of the pelvic bone (especially acetabulum) is being explored. Simple radiographic projections, including specially designed views, although very helpful, often can not provide sufficient information to give a true sense of the fractures.CT,converoly displays the anatomy in a axial plane, thereby providing the missing pieces of information and greatly fascilitating accurate classification of these fractures. In addition, the extent of the soft tissue damage and joint involvement is precisely demonstrated. 10 patients with acetabular fracture, were adimitted to Koryo General Hospital and were taken the CT, were reviewed. Comparing simple radiographic findings with those of the CT, we have made the following conclusions: 1. CT was shown to be useful in the evaluation of the acetabular fractures. 2. CT could detect the pattern of acetabular fracture including degree of fracture fragment, displacement and loose body fragment, and stability of the hip joint. 3. Follow-up of the CT was helful in confirming the extent of bony union of the acetabular fracture. 4. CT was more sensitive than simple radiography in detecting fractures involving the anterior column of the acetabulum.

We performed an epidemiologic survey to investigate the dermatologic problems from cutting oils in metal workers. The personal questionnaires and dermatologic examinations were performed on 360 metal workers who were working at 50 metal industries. The pH meter (HANNA 8520) and the atomic absorption spectrometer(G.B.C. 902) were employed to measure the pH values of cutting oil and the concentration of heavy metals contained in cutting oil respeetively. The results were as follows : 1. The prevalence rates of the dermatologic disorders from cutting oil were 46.0% of eontact dermatitis, 10.9% of black comedone, and 7.1% of paronychia in orders. The dermatologic disorders that seemed to be not directly associsted with cutting oil were callosity(19.1%), burn by metal chips(9.8%), and mechanical injury(5.7%). 2. The localizations of the contact dermatitis and the black cemedone from cutting oil were 84% of hands, 6.6% of face, and 5% af forearms. More detailed localizations of the contact dermatitis and black comedone that developed in hand were 29.6% if finger tip, 27.6% of palm and palm finger, and 19.1% of palm finger only in orders. 3. The prevalence rates of the dermatologic disorders by the of cutting oil were 51.5% of soluble oil, 68.8% of insoluble oil, and 80.8% of mixed cutting oil which containing both soluble and insoluble oil. 4. The mean pH value of aoluble cutting oil was 8.0 and that of insoluble cutting oil was 7.0. 5. The concentrations of heavy metals contained in soluble oil were 32.2 mg/m3 of chrome, 6.42 mg/m3 of nickel, and 4.85 mg/m3 of cobalt. The concentrations of heavy metals contained in inspluble oil were 24.11 mg/m of chrome, 4.63 mg/m3 of nickel, and 2.30 mg/m3 of cobalt.

Direct intraarterial measurement of blood pressure is an important diagnostic procedure in critical patients and premature baby care. Direct measurement was more accepted and confident method in physician than the indirect methods. But the presence of a significant amplification of systolic pressure in peripheral artery may lead to important error. So we have investigated the degree of the systolic pressure amplification from the ascending aorta to the femoral artery in children. Pressure waves recorded in the ascending aorta, aortic arch, diaphragmatic level of the descending aorta, common iliac artery, and femoral artery in 37 patients with congenital heart disease, aged 9 months to 21 years old (mean 7.16 yrs old) during diagnostic cardiac catheterization. The results were as follows 1) Amplification of the systolic pressure increased progressively from the ascending aorta to the femoral artery (16.7%) 2) Diastolic pressure decreased progressively from the ascending aorta to the femoral artery (6.5%) 3) Mean pressure decreased progressively from the ascending aorta to the femoral artery (1.5%) 4) Pulse pressure increased progressively from the ascending aorta to the femoral artery (42.8%) 5) There was significant drop (7%) of the systolic pressure of the ascending aorta compared with that of left ventricle. The results showed that the peripheral amplifications were limited to the systolic and pulse pressure, but the diastolic and mean pressure in peripheral arteries were lower than that of central artery.

Multiple primary tumors are defined as cases involving primary malignant tumors of different histologic origins in one person. The absolute number of reported cases of double primary malignant tumors has increased in recent years diagnostic procedures. Primary adenocarcinoma of duodenum is a rare disease and represents less than 0.5% of all gastrointestinal malignancies. Therefore, synchronous multiple primary cancers of the stomach and duodenum are very rare. Recently, we experienced a case of triple primary malignant tumors of different site originating from the stomach, duodenum and cervix in 71- year-old woman. She had had radiation therapy and chemotherapy for squamous cell carcinoma of the uterine cervix 8 years previously. We performed subtotal gastrectomy and pancreaticoduodenectomy with radical lymph node dissection. She remained healthy without any evidence of recurrence 12 months after the operation.

In spite of vigorous efforts to enhance appropriateness of blood usage in surgery, it is recognized that there are still not a few overuse and misuse of blood products in Korean hospitals. To assure appropriate use of blood, continuous monitoring and controlfling blood orders, particularly for surgical operations, should be implemented. The indicator of 'ratio of crossmatching to transfusion' (C/T ratio) has been focalized on in this regard. The authors investigated C/T ratio for eight hospitals, evenly distributed in their geographical location as well as size. Only elective surgeries operated from March 1 to May 31, 1995 were included for analysis. Standardized survey format was distributed, and retrospective reviews of medical records were performed by volunteer surveyors from each hospital after two sessions of pre- survey education. The results were as follows. Average C/T ratio, for all hospitals and all surgeries, was 1.76. Differences in C/T ratio by sex, months, clinical departments, blood components were not significant. However, the ratio showed increasing tendency with ages. The C/T ratio on the average was not higher, compared with the recommended guideline. However, due to study' s limitations ini standardization of survey method and verification of data, we could not conclude that current status of appropriateness of blood use is satisfactory. In addition, to pervasively use the C/T ratio as a quality indicator for blood use management, supplementary measures, such as standardization of data, should be adopted.

OBJECTIVES: To estimate the weighting for the disability caused by major cancers in Korea using the Delphi method. METHODS: We selected 19 panelists to estimate the disability weighting of major cancers in Korea by using the Delphi method. To select the relevant kinds of cancers, we used National Death Certificate Data produced by the National Statistical Office in 1996. Then the stability of each delphi round was calculated by using the coefficient of variance. RESULTS: The disability weight of major cancers for males was pancreas cancer(0.36), liver cancer(0.35), esophageal cancer(0.30), stomach cancer(0.27), lung cancer(0.26), and colorectal cancer(0.30). The disability weight of major cancers for females was pancreas cancer(0.36), liver cancer(0.34), esophageal cancer(0.29), stomach cancer(0.28), lung cancer(0.26), and colorectal cancer(0.28). CONCLUSION: The results of this study will provide baseline data useful for the measurement of the burden of disease caused by cancers in Korea.

Nitroblue tetrazolium dye reduction test is now widely used for early detection of bacterial infection. Practically nitroblue tetrazolium dye reduction test (N.B.T. test) gives certain clue to rule out any possibility of aseptic inflammation. Authors performed N.B.T. test for 80 orthopaedic diseases and 40 controls, and the results were as followings: 1. Forty-one of 60 subjects with bacterial infection had more than 10% formazan positive neutrophils, and 18 of 20 subjects without bacterial infection showed less than 10%. formazan positive neutrophils, The groups of the elevated N.B.T. responses were mainly the subjects who had osteomyelitis, soft tissue inflammation, pyogenic arthritis, and bone and joint tuberculosis. 2. The mean proportion of N.B.T. positive neutrophils was 3.8±2.78% in 40 controls, 4.7±4.23% in 20 nonifectious group 12.7±10.3% in 12 chronic osteomyelitis, 12.5±10.7% in 15 treated bone and joint tuberculosis, 20.9±15.65% in 15 untreated bone and joint tuberculosis and 20±10.70% in 11 pyogenic arthritis and 7 other soft inflammatory group. 3. In noninfectious group, 7 of 8 subjects with elevated ESR and 3 of 4 subjects with elevated body temperature revealed N.B.T. responses less than 10%. 4. In 23 subjects with the elevated N.B.T. responses as well as leukecytosis, 22 subjects were the groups of bacterial infection and rest 1 was noninfectious in nature. 5. Therefore, the N.B.T. test is found to be useful for the purposes of the early diagnostic aid of the bacterial infection and differential diagnosis between bacterial infections and other diseases.
