In humans, echinococcal species produce cystic lesions primarily involving the liver and lung. Echinococcal infection is caused far more commonly by Echinococcus granulosa than by E. multilocularis, which accounts for less than 5 percent of all cases of hydatid liver disease. Hydatid disease occurs principally in sheep grazing areas, particularly in the Australia, New Zealand, Greece, Yugoslavia, Middle East, and South American countries, but with increasing migration and traveling, this disease now has a worldwide distribution. This disease is rare in Korea and only few cases have been reported. This is a clinical case report of hydatid cyst of liver caused by Echinococcus granulosus in a 52-year-old man who had been dispatched in the Vietnam from 1966 to 1968.

Abstract PDF: BACKGROUND
Hepatocellular carcinomal(HCC) has been considered to be relatively radioresistant. The role of radiotherapy(RT) in the treatment of HCC is controversial. But RT has a role in the treatment of hepatocellular carcinoma as a single or combination modalities. The effect of radiotherapy on HCC was evaluated. Patients and METHODS: From January 1984 through January 2000, a total of 18 patients with unresectable HCC underwent radiotherapy alone or in conjunction with transarterial embolization(TAE). We reviewed the medical ecords of patients treated with RT and measured the tumor size using measured the tumor size using planimetry method. The Kaplan-Meier method was used to calculate the survival rate. RESULTS: The RT patients were 15 men and 3 women. The mean age was 51 years. four(22.2%) of them were accompanied with ascites. Eleven(61.1%) of them were accompanied with liver cirrhosis and their functions were 6, 3, 2 in each Child-Pugh A, B, C, respectively. A partial response(PR) was observed in 2 patients(11.1%), minimal response(MR) in 4 patients (22.2%) and no change(NC), in 11 patients(61.1%), whereas progressive disease(PD) was seen in 1 patients(6%), respectively. CONCLUSIONS: Although the radiotherapy in HCC did not improve the survival rate. it decreased the tmor size. Radiotherapy strengthens the therapeutic efficacy when combined with TAE, but more studies are needed.

Abstract PDF: In Order to evaluate determinants of successful percutaneous transluminal coronary angioplasty (PTCA), PTCA was performed for 172 coronary arterial lesions in 120 patients(89 male, 31 female) at Yeungnam university hospital from Sep. 1992 to Aug 1993. The corinary artery luminal diameter at the site of the original stenosis was eveluated from end-diastolic frames of identical projections of the preangioplasty and immediate post angioplasty. The coronary luminal and balloon diameters were measured with using of computer measuring system. Overall success rate of 172 attempted lesions was 87.2%. Success rate of female patients was 93.5% and higher than those of male patients. According to the clinical diagnosis, success rate in stable angina was 93.7% and higher than those of post myocardial infarction angina, unstable angina and acute myocardial infarcrion. Success rate of American Heart Association type C lesion was 65.5% and lower those of type A(95.7%), type B (89.%). There was significantly difference in preangioplasty luminal stenosis, elastic recoil and length of lesion between successful PTCA group and failed PTCA group. Success rate of lesion location at a bed >45° and presence of intracoronary thrombus were lower than than those of other angiographic findings. In coclusion, primary angioplasty success was affected by specific angiographic factors, Stenosis severity, thrombus, lesion location at a bend >45°, elastic recoil, and length of lesion were the principle of determinants of coronary angioplasty success rate.

A Case of Disappearing Symptoms Developed Repetitively in a Complete Atrioventricular Block Patient Implanted Bipolar Permanent Pacemaker After Converting It into Unipolar System.: Jun Young Kweon, Kyo Won Choi, Dong Gu Shin, Young Jo Kim, Bong Sup Shim, Hyun Woo Lee; Yeungnam Univ J Med. 1994;11(1):181-185.

Abstract PDF: 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.

Abstract PDF: 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.

Abstract PDF: Bronchial carcinoid tumor was a low grade malignant and it was regarded as predictable clinical course and good survivality after surgical resection. But despite of its low grade malignant potentiality, bronchial carcinoid tumor was clearly capable of metastasizing and causing death. We present 2 cases of bronchial carcinoid tumors. One of them was typical carcinoid tumor in 44 year-old female and another was atypical carcinoid tumor in 53 year-old male patient. Currative therapeutic procedure was performed by lobectomy and wedge resection.

Abstract PDF: A free-floating ball thrombus in the left atrium is a rare complication of the mitral valvular disease. A 53-year-old man was admitted for pain and paresthesia on both legs. On admission he had auscultatory sign of mitral stenosis and mitral regurgitation, and the roentgenogram of his chest revealed a slight pulmonary ve..ous congestion, enlargement of the pulmonary conus and cardiomegaly. Laboratory findings including complete blood counts, coagulation studies and blood chemistry were normal. An echocardiographic examination revealed a mitral stenosis and a free-floating ball thrombus in the left atrium. We performed the emergent open heart surgery for removal of the ball thrombus and mitral replacement successfuly with Duromedics 29 mm valve. The size of thrombus was 39 X 32 X 30 mm.
