This study was designed to investigate factors relating to fiscal deficit for regional health insurance. The financial statements for the fiscal year 1990 of nationwide 254 regional medical insurance societies were analyzed. Important findings are summarized below: 1. There were differences in the main reason for the financial deficit among regions when deficit and surplus societies were compared by regions. The total revenue per enrollee, especially revenue from the premium contribution of a deficit society was significantly smaller than that of a surplus society in large cities and counties. On the other hand, the total expenditure per enrollee of a deficit society was larger than that of a surplus society in small cities. 2. Both low premium irate at the beginning of health insurance program and less effort to increase the premium rate were main factors for the smaller revenue from the contribution of a deficit society in large cities and counties. 3. Larger expenditures per covered person of a deficit society in small cities were explained with larger medical expenditures especially for out-patients services rather than larger administrative expenses. 4. A regression analysis showed that utilization rates in out-patient services were significantly associated with income and numbers of total medical care institution per capita within a region where a health insurance society located. Also expenses paid by insurer per visit were associated with the proportion of utilization for tertiary care hospitals as well as the proportion of utilization of public health centers.

Heat stroke, a medical emergency, occurs when the body's thermal regulation is upset and unable to dissipate adequate amounts of heat with a rise in body temperature. It is characterized by hyperyrexia, with a core temperature of 40degrees C or more, hot dry skin, and central nervous system disturbance and usually results in rhabdomyolysis and multiorgan failure. Our case, a 43-year-old healthy male, was caused by a marathon, half course, on a sunny day in late summer. He suddenly fell down on the road and was delivered to a nearby hospital, where a seizure developed. He was transfered to our hospital and then displayed Central Nervous System disturbance, hot dry skin, acute liver failure, rhabdomyolysis, anuric acute renal failure, and disseminated intravasculular coagulopathy. He was treated with general supportive care and hemofiltration. Despite the aggressive management, he died of shock on the fifth day after admission.

Spontaneous spinal epidural hemorrhage(SSEH) represent 0.3%~0.9% of spinal epidural-space-occupying lesions. The therapeutic outcome seems to be determined by the accuracy of the diagnosis and by the time interval between the onset of symptom and surgical decompression. Thus, SSEH is a rare spinal emergency and a diagnostic challenge. We experienced two such cases. In one case, the symptoms were confused with those for a ureter stone, aortic aneurysm, spinal cord infarction. That patient completely recovered spontaneously within 2 hours. In the other case, which was initially diagnosed incorrectly as a cerebral infarction, surgical decompression was performed. That patient recovered completely within 1 month.

A 46-year-old female with abnormal radiologic finding was diagnosed with pancreatic neuroendocrine tumor and multiple hepatic metastasis. Molecular targeted therapy (everolimus) and two times of transarterial chemoembolizations (TACE) were performed before pylorus-preserving pancreaticoduodenectomy (PPPD). After 2nd TACE and PPPD, grade 2 pancreatic neuroendocrine tumor was pathologically confirmed. Four times of additional TACE was done. After size increase of several probable hepatic metastasis in the both lobes of liver, laparoscopic left lateral sectionectomy of liver was performed. After two and half years of left lateral sectionectomy, 7th TACE was performed and the patients have survived without further disease progression. This case suggests that patients with pancreatic neuroendocrine tumor and hepatic metastasis can be treated by TACE, primary tumor resection, surgery for liver metastasis and molecular targeted therapy. Therefore, aggressive multidisciplinary approaches need to be considered for long term survival of patients with pancreatic neuroendocrine tumor with hepatic metastasis.

OBJECTIVES: The purposes of this study were 1) to correlate the carotid intima-medial thickness (IMT) with risk factors of atherosclerosis, 2) to demonstrate the standarized methods of B-mode ultrasound (US) scanning of carotid artery and IMT measurement. MATERIALS AND METHODS: Bilateral carotid arteries of 95 adult volunteers were scanned using 12 MHz linear probe. The mean of bilateral IMT was regarded as the volunteer's IMT, which was measured on the far wall of distal common carotid artery. The normality test for measured IMT and correlation tests between IMT and various known risk factors of atherosclerosis including age, end-systolic blood pressure, end-diastolic blood pressure, fasting blood glucose level, body mass index, life-style data and lipid profiles were performed. Inter-observer and intra-observer variability were evaluated through correlation tests on 20 randomly sampled data. RESULTS: The measured IMT showed normal distribution (mean=0.673 mm, SD=+/-0.1, p=0.494) and the 95th percentile was 0.830 mm. The systolic blood pressure (r=0.101) and body mass index (r=0.200) showed positive correlation but they did not show statistically significant relationships with IMT (p>0.05). The age showed statistically significant correlation (r=0.585, p<0.001), but the other risk factors did not show statistically significant correlation with IMT. The correlation coefficients of inter-observer and intra-observer variability on IMT measurement were 0.8770 and 0.9213, respectively. CONCLUSION: The diagnostic criteria for early carotid atherosclerosis using B-mode US could be estimated from our data. Our measurement protocols showed high reproducibility. The associations between most risk factors that did not show statistically significant correlation in our study and IMT should be confirmed in a population-based study.

BACKGROUND AND OBJECTIVES: The ideal treatment for allergic rhinitis that is refractory to medical therapy is still lacking. Recently, radiofrequency-assisted partial turbinoplasty (RFAPT) has been introduced as a new treatment modality for reduction of inferior turbinate volume. The aim of the study is to evaluate the efficacy of RFAPT for the treatment of allergic rhinitis that is unresponsive to medical therapy and compare the postoperative outcome of RFAPT with that of Laser-assisted partial turbinoplasty (LAPT). SUBJECTS AND METHOD: Forty-eight patients with nasal obstruction due to allergic rhinitis which is refractory to medical therapy were prospectively evaluated with a follow-up period of 3 months. Twenty patients (40 sides) were treated with RFAPT, and 28 patients (56 sides) with LAPT. The the degree of postoperative changes in nasal obstruction, rhinorrhea, itchy nose, sneezing, operation time, operation-associated pain, intraoperative bleeding, duration of crust formation was compared between the two surgical methods. RESULT: There were no significant differences in the improvement of allergic symptoms and intraoperative bleeding between the two groups. Operative time was less in the RFAPT group and crust was formed for a shorter postoperative period. Operation-associated pain was less in the LAPT group. CONCLUSION: The study demonstrates that RFAPT appears to be effective for treating allergic rhinitis whihc demonstrates poor response to medical therapy.

BACKGROUND AND OBJECTIVES: The mucosal epithelium of middle ear and eustachian tube needs hydration to maintain proper amount of moisture. Recent discoveries of various types of water channel proteins (aquaporins ; AQPs) in mucous epithelium suggest that they play critical roles in the regional regulation of water balance. The purpose of this study is to assess the distribution and expression of different subtypes of AQPs in the rat eustachian tube. SUBJECTS AND METHOD: We analyzed the distribution and expression of AQP1, 2, 4, 5, and 7 using RT-PCR, Western blot, and immunohistochemistry study in the rat middle ear and eustachian tube samples. RESULTS: The expression of the mRNA of AQP1, 4, and 5 were observed in the rat eustachian tube and middle ear. The bands of AQP1, 4, and 5 were detected at 28 kDa, 31 kDa, and 26 kDa proteins in the Western blot analysis, respectively. The immunohistochemical analysis demonstrated that AQP1 was expressed in fibroblasts at subepithelial portions of the rat eustachian tube and that AQP4 was observed at the basolateral membrane of the ciliated epithelial cells. The distribution of AQP5 in rat eustachian tube was limited to the apical surface of serous gland cells, but all of the epithelial goblet cells were labeled negative. CONCLUSION: We demonstrated that there are various subtypes of AQP in rat eustachian tube and that they existed at specific cells and sites. This study may be a preliminary study to determine the possibility of relationship between AQP expression and AQP-related disease in the middle ear and eustachian tube.

BACKGROUND: Perindopril. a new second-generation angiotensin converting enzyme inhibitor developed by Servier Research, was administered in essential hypertensive patients in order to observe the clinical effects. METHOD: The changes of blood pressure, heart rate, quality of life, clinical laboratory examinations, side effects, electrocardiogram and echocardiographic left ventricular mass were evaluated before and after 4-12mg of perindopril 12 weeks' administration in 25 essential hypertensive patients(mild 10, moderate 8, severe 5, very severe 2 : male 7, female 18 ; mean age 53.1+/-8.9 years). RESULT: 1) After treatment with perindopril alone, blood pressures were lowered markedly in 17(68%), moderately in 5(20%) and mildly in 2(8%) cases. The average of blood pressures of 25 subjects were systolic 173.1+/-22.8mmHg and diastolic 105.9+/-9.5mmHg before treatment, which were lowered to 125.2+/-14.9mmHg and 83.2+/-9.0mmHg respectively after 12 weeks(p<0.0001). 2) Quality of Life improved markedly in 11(44%) and slightly in 9(36%) cases after perindopril administration. 3) On electrocardiographic follow-up study, three out of five left ventricular hypertrophy with strain, seven out of 13 left ventricular hypertrophy, two out of three ST segment and T wave change and two sinus tachycardia were improved. Echocardiographic left ventricular mass was reduced significantly form 249.4+/-72.7g to 202.9 56.3g after 12 weeks perindopril treatment(p<0.0001). 4) Side effects were 5 cases of dry cough and 3 facial flushing. 5) Final Assessment of perindopril effect including hypotensive effect, quality of life, left ventricular mass regression and side effect showed very useful in 16(64%) and useful in 6(24%) out of 25 subjects. CONCLUSION: Perindopril may be an effective initial single antihypertensive agent for the treatment of varying degree of hypertension, especially with left ventricular hypertrophy.
