During last 10 years we experienced 25 cases of C.N.S. cysticercosis. Now clinical analysis and evaluation of our cases were made and the results are followings; 1. Prevalence in man and women are nearly same and about 70% of cases are distributed between 20-50 years old. 2. According to Nieto's classification, mostly are ventricular (44%) and parenchymal type (36%). 3. Clinical manifestations were IICP (92%), focal neurological deficits (68%), seizure (48%), altered mental status (36%) and others listed on table 7. 4. In ventricular type, IICP and cerebellar dysfunction signs were predominated but seizure and focal neurological deficits were commonly seen in parenchymal type. 5. Subcutaneous cysticercus nodules were palpated in 32% of cases. 6. Positive stool ova was observed in 29% of cases. 7. Radiologic studies revealed as followings: 16% of cases showed abnormal findings on plain film, 84% on angiography, 94% on ventriculography and 100% on computed tomography and myelography. Computed tomography looks like most helpful diagnostic method for C.N.S. cysticercosis, they usually revealed lucent cystic lesion, hydrocephalic findings and contrast enhancement. 8. Suboccipital craniectomy, craniotomy with removal of parenchymal cyst or laminectomy were done according to location and types of lesion. 72% of operated cases revealed good results and mortality was 4% of cases.

BACKGROUND: Primary hepatocellular carcinoma(HCC) is the second cause of cancer death in our country. Hepatitis B virus(HBV) and hepatitis C virus(HCV) are important risk factors for hepatocellular carcinoma. The mechanism of HCC development and the epidemiology in HCV infected individuals are still unclear. In this study, we investigated the epidemiolgical and clinical features of HCC in relation to viral infection. METHODS: We reviewed the medical records of 160 HCC patients retrspectively who had been admitted to one University Hospital located in Seoul between January 1991 and December 1995. Among these patients, 113 patients were positive for HBsAg(B group), 24 for anti-HCV(C group). We compared epidemiological and clinical data between B group and C guoup. RESULTS: Anti-HCV positivity was significantly higher in HBsAg negative patients than in HBsAg positive patients(53.3:1.7%, p<0.01). The mean age of patients in B group was significantly lower than that in C group(52:62yr, p<0.01). In C group, the proportion of Child-Pugh class B and C was significantly larger than that of B group(35.4: 75.0%, p<0.01). In C group, the proportion of transfusion history was significantly larger than that in B group(4.4: 16.7%, p<0.05), and the proportion of drug abuse hestory was significantly larger than that in B group (31.0:62.5%, p<0.01). In C group, the albumin, cholesterol, Gamma-glutamyl transferase leves were significantly lower than those in B group. In B group, the proportion of metastasis was significantly larger than that in C group(31.9:4.2%, p<0.01). Alpha fetoprotein levels greater than 400ng/ml are much more prevalent in group B significantly(67:39.1%, p<0.05). No significant differences in cumulative survival rate(1yr, 2yr) and median survival time were observed between the two groups. CONCLUSIONS: We ascertain that the HBV and HCV are inportant factors in HCC. In epidemiology and clinical features of HCC, there were some difference between the HBsAg and anti HCV positive group. Therefore, on primary health care settings, it is necessary to test for hepatitis C as well as hepatitis B in order to prevent and manage HCC and chronic liver desease.

The purpose of this study was to compare the difference of two survey methods for health services research. Data were collected by means of two types of household survey conducted from March 11 to September 19, 1985. A probability sample of 30,613 persons was taken from 180 Enumerated Districts designated by the Economic Planning Board. The sample was divided into two groups systematically. One group was surveyed by the self-administered questionnaire and the other group was interviewed. Response rates were 81.4% and 90.6% respectively. The data were analyzed by the ratio of the results of the self-administered survey to those of the interview survey. No difference was observed in sex, age, residence, or occupation between the two groups. However the respondents' characteristics were statistically different between the two groups. The major findings of this study are as follows : 1. The morbidity rate was 142.5 per 1,000 persons during the two week period by the self-administered questionnaire survey and 74.3 per 1,000 persons with the interview survey method. The ratio of the morbidity rate by the self-administered questionnaire to that by the interview was 1.92, and the difference between the two rates were due to the personal characteristics. 2. The out-patient utilization rate was 10.2 visits per person per year by the self-administered questionnaire survey and 5.4 by the interview survey, and the ratio was 1.89; the admission rate was 3.2 times per 100 persons per year by the self-administered questionnaire survey and 1.9 times by the interview survey, and the ratio was 1.68. Differences due to the sociodemographic characteristics were greater in the out-patient utilization rates than in the admission rates. 3. Percentages of effective medical care demand were 90.2% in the self-administered survey and 92.3% in the interview survey; the ratio was 0.98 which was less than that of the morbidity rate and medical care utilization. But, differences of effective medical care demand occurred in persons with no occupation, and aged or low educated respondents. 4. Respiratory illness had the highest frequency in the two survey methods. But there was a slight difference between the two survey methods in morbidity composition. 5. It was concluded that data collected by the interview survey were inclined to be underestimated and this problem can be corrected by a modified self-administered survey.

Small cell osteosarcoma is a rare form of osteosarcoma and the histological differential diagnosis from other small round cell tumors (SRCTs) is difficult. The immunohistochemical stain for MIC2 has been considered an useful diagnostic marker for Ewing's sarcoma and primitive neuroectodermal tumors but recently, other SRCTs such as malignant lymphoma and embryonal rhabdomyosarcoma also showed positive reaction. Therefore, the usefulness of MIC2 must still be proven. We experienced a case of small cell osteosarcoma of the mandible in a 25-year-old man. Histologically, the tumor consisted of small round cells that resembled those of Ewing's sarcoma. Immunohistochemically, the tumor cells expressed diffuse strong positive reaction for MIC2 gene products. However, the scanty foci of lacy osteoid material between the tumor cells seemed to be diagnostic of osteosarcoma. The histologic and immunohistochemical findings of this case suggest close relationship between small cell osteosarcoma and Ewing's sarcoma.

Acupuncture with gold needle insertion is utilized in Oriental medicine, and the effect of therapy is represented by anti-inflammatory and analgesic function, But sometimes the needle is erroneously inserted into abdominal organs, and then it may cause dangerous complications. We report a case of multiple gold needles in the abdominal organs without having definete clinical symptoms.

To evaluate the prognostic predictor and clinicopathologic characteristics of the gastrointestinal (GI) mesenchymal neoplasm, we examined 75 cases of GI mesenchymal tumors surgically resected during 8 years from 1983 to 1990. Various histological parameters referrable to the prognosis, including the Ag-NORs count, were analysed. Fifty cases were followed-up for 1 to 7 years. Sixteen out of these fifty cases died during this period. The location of tumor was the stomach in 33 cases, the small intestine in 31 cases and the large intestine in 11 cases, and the tumor size was variable from 2 to 35 cm in diameter. The GI mesenchymal neoplasm appeared as an extraluminal mass in 50 cases, an intramural mass in 17 cases, and an intraluminal mass in 8 cases. Each tumor was composed of spindle or epithelioid cells, the former cell type being more common than the latter (45 vs 30 cases). Mitotic count of the tumor showed the best correlationship with the survival of patients(p<0.05), although the tumor size and necrosis appeared to have some values. The Ag-NORs count was variable and was not significantly correlated with the patient's prognosis(p>0.05). These results indicate that the mitotic count is the most valuable pathological predictor for the prognosis in GI mesenchymal neoplasms.
