PURPOSE: In young male patients who suffered several kinds of trauma with subsequent suspicious reflex sympathetic dystrophy syndrome, we performed three-phasic bone scan in order to investigate its usefulness. MATERIALS AND METHODS: Patients with narrow range of age (21-25. mean 22.8+/-1.3, all male) were included with suspicious reflex sympathetic dystrophy syndrome of 12 feet and 5 hands. Only one was bilateral feet case and 16 were ipsilateral (Rt:13, Lt:3). The etiologic traumas were 4 fractures, 4 sprains, 3 blunt trauma, 2 cellulitis, 1 tendon tear, 1 crush injury, 1 overexercise, and 1 unknown. Radiologically 3 showed osteoporotic changes. Three-phasic bone scans were performed 21.2+/-7.3wks after trauma. RESULTS: According to symptom complex, confirmatory reflex sympathetic dystrophy syndrome 4 cases and suspicious 13 were analyzed. All confirmatory cases (100%) showed increased uptake at delay phase with periarticular accentuation. Of confirmatory 4 cases, 2 showed increased uptake in all three phases (perfusion: P, blood pool: B, and delay: D), and other 2 revealed decreased P but, both increased B and D. Of suspicious 13 cases, 9(69.2%) had increased D (4 periarticular and 5 focal), 2 decreased D, and 2 symmetric D. In 12 foot cases, so-called weight bearing patterns - increased contralateral sole at P and B - were revealed in 7(58.3%). CONCLUSION: Diffuse periarticular increased uptake at delay phase of three-phasic bone scan was a compatible finding to reflex sympathetic dystrophy syndrome in young male patients whose symptom complex strongly designated post traumatic reflex sympathetic dystrophy syndrome.

BACKGROUND: Reperfusion of ischemic myocardium is clinically encountered during thrombolytic therapy of acute myocardial infarction, percutaneous transluminal coronary angioplasty(PTCA), and coronary artery bypass graft(CABG). Reperfusion results in endothelial dysfunction characterized by a reduced release of endothelium-derived relaxing factor(EDRF) in animal studies. Studies with experimental animals have emphasized the role of oxygen free radicals and lipid peroxidation in pathophysiology of reperfusion injury and myocardial stunning. The object of this study is to determine whether endothelial dysfunction was developed after open heart surgery and to evaluated the role of oxygen free radical and lipid peroxidation in reperfusion injury. METHODS: The study group was comprised 13 patients who underwent open heart surgery(male/female : 2/11, mean age : 43+/-4 year, Atrial septal defect in 4, Ventricular septal defect in 1, Mitral regurgitation in 2, Tetralogy of Fallot in 1, and Aortic stenosis and Regurgitation with Mitral stenosis in 5 patients). The endothelial function was evaluated with the vasomotor response to acetylcholine and nitroglycerin by change of arterial diameter during the continous infusion of acetylcholin, from 10(-9) to 10(-6) molar concentration to the coronary artery and intracoronary injection of 200microg nitroglycerin after acetylcholine infusion. The infusion study was performed before and 10 days after surgery. For analysis of the role of oxygen free radical and lipid peroxidation in reperfusion injury, blood samples for malondialdehyde and neutrophil respiratory burst test(hydrogen peroxide amount of neutrophils) were obtained in pre-declamping of aorta and 5 min, 10 min, and 20 min after declamping of aorta from coronary sinus. RESULTS: 1) The vasoconstrictor response to acetylcholine, 10(-9) to 10(-6)M concentration, at proximal and distal left anterior descending coronary artery, were increased significantly in post-operation infusion study but there was no singnificant difference in vasodilator response to nitroglycerin. 2) The mean absorbance value of malondialdehyde(MDA) in pre-declamping and 5min, 10min, and 20min after reperfusion were 96+/-12, 73+/-12, 89+/-11 and 77+/-12, respectively. There was no significant difference in plasma MDA level and hydrogen peroxide amount of neutrophils after reperfusion(aortic declamping). CONCLUSION: These data suggest that endothelium dependent vascular relaxation is impaired in patients with open heart surgery and post-ischemic reperfusion injury may be responsible for the abnormal response. But we did not determine the role of lipid peroxidation and oxygen free radical in reperfusion injury.

BACKGROUND: Unstable angina is a critical phase of ischemic heart disease, but there are no reliable noninvasive methods of assigning patients to different prognostic actegories. Recently cardiac Troponin-T has been developed as a new myocardial specific marker, especially myocardial injury. We investigated the value of the Troponin-T in unstable angina to determine whether the increase of cardiac Troponin-T might be a useful predictor of prognosis. METHODS: Unstable angina is defined as Braunwald classification(Class I, II, III). CLass I is new onset of severe angina or accelerated angina and no rest pain, class II is angina at rest but not within preceding 48 hour, and class III is angina at rest within 48 hour. We studied 16 cases of unstable angina(male:10, mean age:57+/-2year). We measured Troponin-T and CK-MB at admission, after 6 hours, and every 8 hour for 2 days. For the determination of serum Troponin-T, an enzyme immunosorbent assay (Boehringer Mannheim, ES 300 analyzer) was used. Above 0.1ng/ml was regarded as positive. During the admission, we investigated the myocardial infartion, sudden death, and the need of emergency PTCA and CABG. RESULTS: 1) Among 16 unstable angina patients, there are 12 patients in Class I(range 0.001-0.13, mean SD 0.04 0.01, median 0.02ng/ml) and 4 patients in Class III(range 0.03-1.56, mean SD 0.39 0.2, median 0.27ng/ml) and 4 patients showed positive value of Troponin-T. One was in Class I and the others were in Class III. 2) During the admission, one patient expired due to cardiogenic shock preceding inferior myocardial infarction, and 2 patients progressed non-Q wave myocardial infarction(NQMI). These 3 patients were in unstable angina Class III and had positive Troponin-T value. In Class I, one patient performed emergency CABG due to consistent chest pain at the sixth hospital day. These patient had negative Troponin-T value. 3) CK-MB increased in one patient with NQMI, and the other patients were not increased. CONCLUSION: Cardiac Troponin-T in serum appears to be a more sensitive indicator of myocardial cell injury than serum creatine Kinase MD activity, and its detection in the circulation may be a useful porgnostic indicator in patients with unstable angina.

Prosthetic valve endocarditis(PVE) is not infrequent and one of the serious complications of cardiac valve replacement despite advances in antimicrobial therapy, diagnostic techniquens and surgical procedures. Although the incidence of PVE may be declining, the absolute number of cases of this infection is increasing. In patients with a prosthetic valve, fever, a regurgitant heart murmur, peripheral manifestations of infective endocarditis and postitive blood cultures, the diagnosis of PVE is evident. We have reviewed our experience with 13 patients with PVE from October 1976 through August 1983. During this period valve replacements were performed in 686 patients, with an infection rate of 1.9%. PVE currently accounts for approximately 14% of the total number of cases of infective endocarditis seen at Seoul national University Hospital. PVE occurred more often after multiple valve replacement than after replacement of single valve alone. Blood cultures were positive in 69% cases of PVE. Systemic emboli could be seen in 54% of patients with PVE and overall mortality was about 23%.

BACKGROUND AND OBJECTIVES: Several echocardiographic methods, such as ejection fraction, fractional shortening, and Doppler tissue imaging (DTI), have been developed to quantify systolic function but all had several important limitations. The purpose of this study was to quantify the regional wall motion abnormality, using strain, in an acute myocardial infarction, compared with a visual estimation. SUBJECTS AND MEHTODS: Forty-five patients, with acute anterior (n=28) and inferior myocardial (n=17) infarctions, who underwent color DTI, were examined using longitudinal strain and standard echocardiography, and the results were compared with 54 normal controls. A total of 594 segments [3 segments (apical, mid and basal portion) of septum and inferior wallx99 patients] were evaluated. RESULTS: In the normal control group, the strain was uniformly distributed in all segments (-20%~-23%). In the infarction groups, the strain was negatively related with the wall motion score. The strain of the apical segments and mid-septum was decreased in the anterior wall infarctions, and the strain of basal septum and mid to basal inferior wall was decreased in the inferior wall infarctions. The dyskinetic segments showed positive strain. CONCLUSION: This study validates strain as a superior method for the quantification of the regional wall motion abnormality in an acute myocardial infarction than visual estimation.

Hemobilia is a status of bleeding into the biliary tract, which is caused by abnormal communication between the intrahepatic blood vessels and biliary tract, and is a rare cause of upper gastrointestinal hemorrhage. Most cases of the hemobilia originating in the gallbladder are related to gallstones. However, hemobilia is a rare complication of calculous cholecystitis. We report a case of hemobilia as a complication of calculous cholecystitis in a patient given continuous aspirin medication.

Common metastaic sites of hepatocellular carcinoma include lung, peritoneum, adrenal gland and bone, but rarely, skin can be metastatic sites. Although hepatocellular carcinoma is the third commonest malignancy in Korea, cutaneous metastasis from hepatocellular carcinoma was rarely reported. Cutaneous metastasis from malignant neoplasm of the internal organ occur at the variable stage and the growth pattern of cutaneous lesions is nonspecific and various, so the differential diagnosis of skin lesions must be considered to other malignant condition. We report a case of cutaneous metastasis from recurrent hepatocellular carcinoma that was confirmed by skin biopsy with immunohistochemical stain.

Congenital hepatic fibrosis (CHF) is an autosomal recessive disease, presenting principally in children or young adults with portal hypertension, and infrequently associated with cholangitis. It is associated with renal malformation and Caroli's disease. The diagnosis of CHF is usually confirmed by its typical histological features. Cholangitis is a severe and frequently fatal complication. We report a 22-year-old man with congenital hepatic fibrosis who showed the cholangitis without radiological features of cystic dilatation or stone of intrahepatic ducts.

Combined double chambered right ventricle(DCRV) and discrete subaortic stenosis(DSAS) is a rare entity on which only 12 cases have been reported in the literature. We presented a case of combined DCRV and DSAS in an 18 year old girl. She had type II(thin membranous type) DSAS and the peak systolic prssure gradient between aorta and left ventricle was 38 mmHg. Aberrant muscle bundle was found on the right ventriculography and the pressure gradient in the right ventricle was 35 mmHg. She also had aortic regurgitation, persistent left sided superior vena cava and extracardiac malformations such as kyphoscoliosis and congenital cloacal anomaly.
