The geographical distribution of active physicians who graduated from medical schools before 1985 were studied. Those who had emigrated, hold non-medical jobs, are in the military service, or work as public health physicians and resident staff were excluded from the study. A total of 27,728 physicians were analyzed. Our studies have shown a relationship between the location of the medical schools from the which the physicians have graduated and the geographical regions in which they practice. A statistically significant number of physicians are working near the medical colleges from which they have graduated. That is, those who had graduated from medical schools located in the southern area of the country are presently working in the same region. This relationship was shown to be especially significant for older physicians and female doctors, who work around the area of the medical colleges from which they graduated.

BACKGROUNG AND OBJECTIVES: Diet is the basic and principal therapeutic modality for hyperlipidemia. However, diet therapy alone showed variable responses in lowering lipid levels in different studies. This research is to prove the effect of diet and Apo E polymorphism on the variation of serum lipid profile in Korean males. MATERIALS AND METHODS: To evaluate the gene-diet interation, serum total cholesterol (Chol), triglycerides (TG), HDL-cholesterol and LDL-cholesterol (HDLc, LDLc), lipoprotein (a) (Lp (a)), and fasting blood glucose (FBS) were measured with Apo E genotyping in vegeterians (group A, n=154) and in healthy Korean male adults (group B, n=150) of similar mean age (50.1 vs. 49.3). RESULTS: Lipid profiles showed significantly lower levels in group A compared to group B (Chol 168.3+/-30.5 mg/dL vs. 181.3+/-33.4 mg/dL, p<0.001;TG 131.0+/-62.9 mg/dL vs. 149.4+/-76.7 mg/dL, p=0.023;HDLc 56.0+/-11.0 mg/dL vs. 56.9+/-11.5 mg/dL, p=0.509;LDLc 92.5+/-28.1 mg/dL vs 100.6+/-29.9 mg/dL, p=0.016;Lp (a) 22.1+/-14.6 mg/dL vs. 26.9+/-13.8 mg/dL, p=0.004;FBS 85.1+/-14.1 mg/dL vs. 102.7+/-16.6 mg/dL, p<0.001). The Apo E genotyping showed Epsilon3/3, 64.1%; Epsilon3/4, 20.7%;Epsilon2/3, 11.8%;Epsilon2/2, 1.3%;Epsilon4/4, 0.6% in the combined groups. The distribution was similar in both groups. Chol and LDLc were significantly (p<0.05) higher in Epsilon3/4 allele group compared to other allele groups among non-vegetarians. On the other hand, Chol and LDLc were significantly (p<0.01) lower in vegetarians compared to non-vegetarians only in Epsilon3/4 allele group. CONCLUSION: Vegetarian diet significantly lowered Chol, TG, LDLc, Lp (a) and FBS levels. Significant lipid lowering effect of vegetarian diet was noted in Apo E allele Epsilon3/4 group which had significantly higher Chol and LDLc levels without diet intervention. These data suggest that the influence of diet on serum lipid profiles differ according to apo E genotypes.

It is very important to estimate the future medical care expenditure, because medical care expenditure escalation is a big problem not only in the health industry but also in the Korean economy today. This study was designed to project the medical care expenditure in view of population age change. The data of this study were the population projection data based on National Census Data (1990) of the National Statistical Office and the Statistical Reports of the Korea Medical Insurance Corporation. The future medical care expenditure was eatimated by the regression model and the optional simulation model. The significant results are as follows; 1. The future medical care expenditure will be 3,963 billion Won in the year 2000, 4,483 billion Won in 2010, and 4,826 billion Won in 2020, based on the 1990 market price considering only the population age change. 2. The proportion of the total medical care expenditure in the elderly over 65 will be 10. 4% in 2000, 13.5% in 2010, and 16.9% in 2020. 3. The future medical care expenditure will be 4,306 billion Won in the year 2000, 5,1101 billion Won in 2010, and 5, 699 billion Won in 2020 based on the 1990 market price considering the age structure change and the change of the case-cost estimated by the regression model. 4. When we consider the age-structure change and inflation compared with the preceding year, the future medical care expenditurein 2020 will be 21 trillion Won based on a 5% inflation rate, 42 trillion Won based on a 7.5% inflation rate, and 84 trillion Won based on a 10% inflation rate. Consideration of the aged (65 years old and over)will be essential to understand the acute increase of medical care expenditure due to changes in age structure of the population. Therefore, alternative policies and programs for the caring of the aged should be further studied.

It has been widely accepted that complete surgical resection of hepatoblastoma is essential for long-term survival. But unfortunately less that 50% of hepatic tumors in children can be totally removed at the time of diagnosis. This report is to present the experience of successful resection of hepatoblastoma after concurrent radiotherapy with transarterial chemoinfusion in a child. We believe this modality of treatment enables complete resection of unresectable hepatoblastoma, which is resistant to the systemic chemotherapy.

OBJECTIVES: This study describes the risk factors affecting the unexpected readmission of 261 patients who were discharged from a university hospital in Seoul. METHODS: This case-control study reviewed medical records of inpatients who had been discharged from a hospital between 1 August 1995 and 31 October 1995 after the treatment for general diseases. The cases were 68 patients who were readmitted unexpectedly within 28 days of discharge from an index stay, and the controls were 193 patients who were discharged without readmission during the study period. RESULTS: Logistic regression analysis results were as follows; Patients who had no operation during their hospital stay were more likely to be readmitted unexpectedly than patients who had operation. Patients who had 1 or 2 parts of their body being involved in treatment were more likely to be readmitted unexpectedly than patients who hand more than 3 parts of their body being involved in treatment. Patients who had complications after surgery were more likely to be readmitted unexpectedly than patients who had no complications. Insufficient discharge planning caused unexpected readmissions. CONCLUSIONS: Discharge planning education should be extended to health care providers. And the assessment of discharge planning should be evaluated. Readmission is often necessary for the treatment of related problems originating from initial hospitalization, which causes cost problems. Unexpected readmission is preventable and the models for readmission can serve as a valuable clinical tool for high risk patients.
