Angiogenesis, the induction of new capillaries and venules, is associated with tumor growth. This study was designed to determine whether cervical carcinomas are angiogenic, and to investigate whether tumor angiogenesis can serve as a prognostic factor in cervical carcinoma. Surgical specimens of 47 cervical carcinomas were immunohistochemically stained specifically for endothelial cells with factor VIII-related antigen to identify all vessels. Microvessels were counted from photographs of 200x microscopic fields. In addition, thirty-seven cases were studied by immunohistochemical means using the monoclonal antibodies for PCNA and for Ki-67 to determine tumor cell proliferation rates in cervical carcinomas. The microvessel count(MVC), the PCNA labelling index, and the Ki-67 index were calculated and compared with known prognostic factors and disease free survival rates in cervical carcinomas. A wide range in the MVC count(range 12-100 mean=38.2+/-19.2), the PCNA labeling index(8-69% mean=33.6+/-15.2%), and in the extent of Ki-67 staining(0-43% mean=10.3+/-10.5%) was observed, indicating considerable variation of tumor angiogenic activity and tumor growth rates. This study showed statistically significant correlations in disease free survival rates with both lymph node status and the microvessel count. However, there was no significant difference in disease free survival rates between tumor stage, age, the PCNA labelling index, and the Ki-67 index.

Internal hernia is an unusual cause of the intestinal obstruction. The advances of CT make the diagnosis more easier than in the past. We report one case of internal hernia with herniation of the ileum into the lesser omenturn. The diagnosis could be made when abdominal radiographs showed fixed clustering of the small bowel loops in upper abdomen medial to the stomach. CT and ultrasound showed characteristic interposition of the ileum between the left hepatic lobe and the stomach.

PURPOSE: The purpose of this study is to assess the sonographic findings of Osgood-Schlatter disease with correlation to radiographic findings and to determine value of sonography in the diagnosis of Osgood-Schlatter disease. MATERIALS AND METHODS: The population consist of 22 cases of Osgood-Schlatter disease and 15 healthy subjects of the same age range for comparison. The sonographic study was carried out with real time units equipped with linear probe of 7 MHz frequency. Radiography and sonography were done in all cases and follow-up sonography was performed in 10 cases. RESULTS: The sonographic features of the Osgood-Schlatter disease were swelling of cartilage over the anterior tibial tuberosity ossification center in 16 cases, fragmentation and/or irregularities of the ossification center of the anterior tibial tuberosity in 14 cases, localized thickening of the pateliar tendon in 14 cases, ossicles in the thickened pateliar tendon in 3 cases, and distension of the infrapatellar bursa in 2 cases. Fifteen of 22 cases of Osgood-Schlatter disease had abnormal findings on radiographs and sonograms. Out of 7 cases which had normal radiograph and abnormal findings on sonogram, 6 cases showed pateliar tendon thickening, cartilage swelling, and/or distended infrapatellar bursa and one case showed fragmentation of anterior tibial tuberosity on sonogram. CONCLUSION: Sonographic evaluation of Osgood-Schlatter disease provided a clear picture about pathologic changes in the superficial soft tissues and in the cartilage and also yielded the same diagnostic information on bony change as radiography Sonography is a reliable and useful method for the evaluation of young patients with clinically suspected Osgood-Schlatter disease.

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.

Korean Journal of Preventive Medicine 1987;20(2):287-300
Island regions suffer from a shortage of health care in part because they are less developed, they cover a widespread area relative to the population, and due to transportation barriers. The purpose of this study was to assess the level of illness and the magnitude of medical care utilization, and to investigate the determinants of utilization in these area. The data were collected by means of a household survey conducted from February 16 to 25, 1987 on 5 islands which were selected in consideration of the size of the population, the distance from the main land, and the distribution of health care facilities. The household response rate was 89.1% (491 of 551 households), and 1971 persons were surveyed. The major findings of this study are as follows: 1) The morbidity rate of the island inhabitants was 27.7% during the two weeks, and 25.5 chronic illnesses and 9.1 acute illnesses per 100 persons, were noted. Differences in the magnitude of illness were statistically significant by sex, age, education, and family size. 2) The magnitude of total ambulatory care utilization was 16.8 visits per 100 persons during the two weeks, which was less than that of other regions; and differences in the magnitude of total ambulatory care were statistically significant by sex, age, education, occupation, and family size. 3) Unmet needs were classified as 56.0% in chronic illnesses and 19.6% in acute illnesses; and differences in unmet needs were statistically significant by sex, age, education, occupation, income, and family size. 4) Statistically significant determinants in medical care utilization included the frequency of acute illness and chronic illness, and income in total utilization; the frequency of chronic illness and acute illness, and medical care insurance in physician visits. 5) According to the results of the path analysis, need factors had the greatest effect on utilization, and predisposing factors had more indirect effects through enabling or need factors than direct effects.
