CT scans of 23 patients with gallbladder carcinoma were retropectively reviewed to determine the incidence of lymphatic spread and to access the pattern of regional lymph node metastases. The lymphatic spread were noted in 74%(17/23). The involved patterns of regional lymph node metastases were nodes of porta hepatis 65%, portocaval nodes 41%, superior pancreaticoduodenal nodes 47%, posterior pancreaticoduodenal nodes 59%, nodes around the celiac trunk 35%, nodes around the superior mesenteric artery 29% and paraaortic nodes 35%. The findings suggested that the pattern of regional lumph node metastases in gallbladder carcinoma occurred along the normal lymphatic pathway of the gallbladder.

A case of intracerebral tension pneumatocele as a complication of an Osteoma in the Fronto-ethmoid sinus is reported. The commonest causes of intracranial air are head trauma and neurosurgical procedures. Less common etiologies include infection due to gas-forming organisms, mucoceles, tumors(e.g. osteomas carcinomas pituitary adenomas peripheral nerue tumors) and congenital neurenteric cysts or dural defects. Computed tomography permitted rapid diagnosis including localization of the air thus facilitating prompt treatment.

We have studied 1927 cases of primary tumor patients, who were admitted, managed and registered at Cancer Center of Maryknoll Hospital from Nov. 1985 to Jun. 1988. Of these, 50 cases were metastasized to central nervous systems, and the cases of brain metastases were 31 cases. This report presents an analysis of 31 cases of metastatic brain tumors. The results are as followings: 1) The sexes were represented with 20 males and 11 females. In 20 cases(65%), the metastases occurred between the 6th decade and 7th decade. 2) The most frequent anatomical site of brain metastases was brain parenchyme(67.7%). 3) The most frequent site of primary malignancy was lung(45.2%), and the next order was choriocarcinoma of the uterus. 4) The clinical symptoms and signs of metastatic brain tumors were headache(87%), nausea, vomiting(35.5%) orderly. 5) In C-T scan findings, the metastatic brain tumors presented hyperdense area at 50% of cases before contrast enhancement, and were enhanced nearly almost of cases. 6) In cases which could be treated surgical procedure, radiation and chemotherapy seemed to improve the prognosis.

This study was performed to evaluate the semiquantitative food frequency questionnaire used to obtain information about. dietary patterns of adults in a rural county, Yang-pyeung Gun. The study population was 1311 adults aged 17~85 years. And well-trained interviewers interviewed subjects in 1990, 1992, 1993. The results are as follows. 1) Nutrients intake calculated from each questionnaire showed significant difference, because the number of question was not same(fifty questions in 1990, eighty questions in 1992, 1993). 2) Estimated nutrients intake from separate food items was significantly different when food items are combined in one question. 3) The agreement of nutrients intake level except vit C were high when the subjects are cross-classified by their ranks on the nutrients intake level from items in both questionnaires and on the nutrient intake level from items in each questionnaire. 4) And analysing this study data by multiple stepwise regression, we selected twenty seven food items whic could explained over 85% of inter-individual variation of nutrients(energy, carbohydrate, fat, protein, vit A, vit B1, vit B2, vit C, Ca). From above results, we suggested that it is neccessary to standardize questionnaire and perform validity studies.

Intracranial chondromas are extremely rare tumors, but when present, are generally related to the synchondrosis of the base, and they have several distinct features. They are slow growing benign tumors, and plain roentgenogram frequently reveals lytic lesion and stippled calcification at base of the skull. They are radioresistant, and surgical removal is treatment of choice. We report the rare case of chondroma arisen from base of the skull which diagnosed by brain CT and confirmed by operation.

Despite of their frequent occurrence among the brain tumor, meningiomas are rarely seen as a multiple growth. Most authors report an incidence ranging from 1 to 3% of all meningioma prior to the introduction of computed tomography. After the CT has introduced, diagnostic problems involved with multiple meningiomas were resolved, and its reported incidence was arisen to 8~8.9% of all meningiomas. It may be difficult to differenciate multiple meningioma from the special varient(forme fruste) of von Recklinghausen's disease. Although the pathogenetic factors related to the multiple meningiomas are unknown, various theories of the etiology have been studied and reported. We report a patient with multiple meningioma without evidence of von Recklinghausen's diseases.

OBJECTIVES: To find differences in Framingham risk scores which predict the probable risk of future cardiovascular disease, among three different occupational categories. METHODS: Subjects were selected from respondents of the 3rd Korean National Health and Nutrition Examination Survey. A total of 2,059 employed people between 20 to 59 years old were selected. The occupational categories were professional and office workers, salespeople and service workers and technicians and elementary occupations. The Framingham risk score was calculated to find the risk of cardiovascular disease within the next 10 years. In addition socio-demographic characteristics, life-styles, the prevalence of chronic disease, and cardiovascular disease were compared among the occupational categories. RESULTS: The average Framingham risk score was 2.77+/-6.44 for professional and office workers (n=771), 5.95+/-6.10 for salespeople and service workers (n=603) and 7.07+/-5.87 for technician and elementary occupations (n=685) Statistically significant multiple regression equations were derived (p<0.001). CONCLUSIONS: Framingham risk scores of technicians and elementary occupations were highest which suggests that this occupational group has the highest risk of cardiovascular disease.

In this paper, a new superimposition scheme using a computer vision system was proposed with pairs of skull and ante-mortem photographs, which were already identified through other tests and DNA fingerprints at the Korea National Institute of Scientific Investigation. In this computer vision system, an unidentified skull was caught by video-camcoder with the MPEG and the other ante-mortem photograph was scanned by scanner. These two images were processed and superimposed using pixel processing. This recognition of individual identifications by anatomical references can be performed on the two superimposed images for many big cases like as Guam KAL accident in 1997.
