Recently, several reports of extrahepatic hepatocellular carcinoma metastasis demonstrated by technetium-99mTc-IDAs scan have shown that 99mTc-IDAs can be used to detect extrahepatic metastasis in hepatocellular carcinoma. We report here a case of hepatocellular carcinoma with pulmonary nodules that were demonstrated as metastasis in nature by the use of the 99mTc-DISIDA. The findings in this case and several reports reviewed here suggest that the 99mTc-DISIDA scan may be a useful diagnostic agent that can detect the extrahepatic metastasis of hepatocellular carcinoma and stage the disease. But more clinical study in needed to establish the position of 99mTc-DISIDA in the field of diagnosis of extrahepatic hepatocellular carcinoma.

We studied the incidence and results of treatment of secondary hypertension in Yeungnam University Hospital. Nineteen hundred fifty patients with hypertension were included from march 1990 to march 1994. We analysed the prevalence of secondary hypertension and results of treatment. The incidence of secondary hypertension in Yeungnam University Hospital was six percent. The most common underlying causes of secondary hypertension was renal parenchymal disease. Patients with three forms of potentially reversible secondary hypertension, namely, renovascular hypertension, endocrine disease, exogenous hormone, were assed to determine whether surgery or withdrawal of the exogenous hormane had led to an improvement in blood pressure control. The incidence of secondary hypertension in Yeungnam University Hospital was low(6%), but some of these are curable. Thus it is very inportant that evaluate the secondary hypertension.

OBJECTIVES: It is the objective of this study to compare hepatotoxicity of nickel chloride and cadmium chloride with each other through IPRL(Isolated Perfused Rat Liver) method. METHODS: Biochemical indicator of hepatic function such as AST(aspartate aminotransferase), ALT(alanine aminotransferase), LDH(lactate dehydrogenase) and perfusion flow rate were used as the indicator of hepatotoxicity. Oxygen consumption rate were used as viability indicator. 300(+/-50) g - weighted rats were allocated randomly to each group(0 micrometer, 50 micrometer, 200 micrometer NiCl2 and CdCl2 exposure) by 5, totally 25. After Krebs-Ringer bicarbonate buffer solution flowed into the portal vein and passed the liver cell, it flowed out of vena cava. Liver was administered with each NiCl2 and CdCl2 of each concentration and observed with buffer solution sampling time. Buffer which got out of liver was sampled and then biochemical indicator of hepatotoxicity was measured. RESULTS: AST, ALT, and LDH in buffer increased with sampling time much more in CdCl2 exposure group than NiCl2 exposure group in both 50 and 200 micrometer and statistical significance was verified with 2-way repeated ANOVA. Viability was decreased more and more in all substances during passed time. CONCLUSIONS: It is inferred that CdCl2 has stronger hepatotoxicity than NiCl2. IPRL method would be used widely for acute hepatotoxicity when considerating the benefit of it.

PURPOSE: To investigate quantitative and morphometric endothelial changes in phakic eyes implanted with an iris-fixed phakic intraocular lens in Korean patients. METHODS: We prospectively examined the endothelial cell density (ECD), ECD loss (ECL), coefficient variations (CV), and frequency of Hexagons (6A) in 46 phakic eyes implanted with an iris-fixed phakic intraocular lens. The effect of anterior chamber depth (ACD) and diopter of iris-fixed phakic intraocular lens on ECD was statistically analyzed. RESULTS: Preoperative mean ECD was 2923+/-257 cells/mm2. ECL at postoperative 1, 3, 6, 12, and 24 monthswas 0.71%, 0.88%, 0.70%, 0.64%, and 2.34%. It was significant only in the month 24 results. The mean CV value at the same time was 0.343, 0.342, 0.334, 0.329, 0.326, and 0.338. The change was significant at the 12th month. The mean 6A value at the same time was 58.2%, 57.8%, 59.7%, 59.6%, 60.1%, and 58.8%. There was no significant change in 6A value. Preoperative ACD and diopter of iris-fixed phakic intraocular lens didn't affect the ECD change. CONCLUSIONS: This two-year follow-up study of changes in endothelial cells after implantation iris-fixated phakic intraocular lens showed statistically significant decreases in the cells, which is not very significant considering the physiologic reduction rate of the cells. Thses decreases showed a tendency to be stabilized with recovery of morphological changes. Further long-term follow-up is needed to determine its long-lasting effect.

Clinical observations were made on 349 cases of acute drug intoxication who were visited to emergency room of Yeungnam University Hospital during recent 7 years from January 1984 to December 1990. The following results were obtained. 1) Total number of cases of acute drug intoxication was 349 which was 0.39% of the total patients of the emergency room during the same period. 2) The ratio of male to female was 1.1:1. The age incidence was highest in the third decade (26.7%). The monthly incidence was highest in May. Higher frequency was observed in summer season. 3) The most common drug of the intoxication was pesticides and herbicides (71.9%), the remainders were miscellaneous drugs (11.2%), sedatives (7.7%), rodenticides (6.3%) and unknown drug (3.2%) in orders. 4) The most common cause of drug intoxication was suicide (69.1%) and the others were accident, unknown cause, intention in orders. 5) Main clinical manifestations were the impairment of consciousness, nausea, vomiting and convulsion. Physical examination revealed increased pulses, increased blood pressure, miosis of the pupil and sweating. Above symptoms and signs were more prominent in pesticide intoxication. Leukocytosis, glycosuria and abnormal LFT were common findings in acute intoxications. 6) The complications were developed in 18.3% among 349 cases and the most common complication was respiratory failure, pneumonia, cardiovascular collapse and pulmonary edema in orders. 7) Overall mortality rate was 8.3% of total cases and mortality rate was highest in herbicide intoxication (22.2%).

Pacemaker malfunctions are secondary to alterations of the preset pacing rate, irregular pacing failure of sensing, failure of cardiac capture or depolarization, and various combinations of these events. A 76 years old male patients was admitted due to pacemaker malfunction. 2 years ago, he was diagnosed as complete atrioventricular block. And then bipolar permanent pacemaker was implanted. Since then syncopal attack developed repetitivly. 12 lead ECG and 24 hour holter moniter monitoring, revealed pacing and sensing failure, thus we converted bipolar system into unipolar system. since then syncopal attack did not developed again.

Purpose: The role of paraaortic lymph node dissection (PALND) in colorectal cancer (CRC) has been less evaluated than surgical treatments for other distant metastases. We evaluated surgical outcomes after PALND and identified prognostic factors. Methods: The medical records of patients who underwent PALND for paraaortic lymph node metastasis (PALNM) were reviewed retrospectively. All patients were categorized into the M1a group (isolated PALNM, n = 27), and the M1bc group (distant metastases other than PALNM, n = 26). Three severity factors (PALNM-SF: number of harvested paraaortic lymph nodes [hLN], ≥14; number of metastatic paraaortic lymph nodes [mLN], ≥5; and lymph nodes ratio [mLN/hLN], ≥0.5) were defined to determine their effects on survival. Results: The 5-year overall survival (OS) of the M1a and M1bc groups were 61.1% and 6.4%, respectively (P = 0.0013). The 5-year disease-free survival (DFS) of the M1a group was 47.4%, and the 3-year DFS of the M1bc group was 9.1% (P < 0.001).Patients with 2 or more PALNM-SFs showed worse OS than those with 1 PALNM-SF (P = 0.017). In multivariate analysis, M1bc (non-isolated PALNM) was the only significant factor for survival. In the M1a group, patients with 2 or more PALNMSFs showed significantly worse survival than those with a single PALNM-SF. In multivariate analysis, 2 or more PALNM-SF was a significant factor for survival. Conclusion PALND for CRC provided favorable outcomes in the survival of an isolated PALNM, although this was uncertain for non-isolated PALNMs. The PALNM-SFs helped assess the prognosis after PALND.

Background: The purpose of this study is to explain the factors influencing the incurrence of catastrophic health expenditure of national health insurance households using panel data observed over a long period. Methods: The study targeted 3,652 households who had no censoring during the 11-year survey period (2007–2017) and householders whose insurance type was consistently maintained as national health insurance. Generalized estimating equations were adopted to identify factors affecting the occurrence of catastrophic health expenditure at 20%, 30%, and 40% threshold levels. A subgroup analysis was conducted by categorizing groups depending on the existence of the elderly in the household. Results: For the last 11 years, the incidence of catastrophic health expenditure in the households without the elderly decreased slightly at all threshold levels, but the households with the elderly seemed to be increased. At baseline, household type showed a statistically significant relationship with all other variables. The results of generalized estimating equations analyses show that household income was not significant at all threshold levels in the households without elderly. On the other hand, in the households with the elderly, the 2nd (odds ratio [OR], 1.33–2.05) and 3rd quintile groups (OR, 1.25–2.55) were more likely to have catastrophic health expenditure compared to the 1st quintile of household income group. Conclusion As the amount of health expenditures relative to the ability to pay is increasing in households with the elderly, the application of an intervention followed by consistent monitoring is needed. This study found that there were differences in influencing factors according to the presence of the elderly in the households. In particular, in households with the elderly, interesting results have been drawn regarding the occurrence of catastrophic health expenditure in the near-poor, so additional research is required.
