OBJECTIVES: Medical complications are common and often serious in patients with eating disorders, however, little is known about complications in patients with bulimia nervosa. METHODS: We conducted a retrospectively investigation of clinical characteristics and hematologic, biochemical, hormonal, and bone density evaluations in 90 Korean women with bulimia nervosa together with 100 healthy Korean women of comparable ages. RESULTS: In patients with bulimia nervosa, 20% were anemic, 3.3% were hypokalemic, 14.4% had increased alanine aminotransferase, 24.4% were lower in serum protein, 8.8% were hypercholesterolemia, and 77.8% were hyperamylasemia. Osteopenia at any one site was identified in 26.7% of patients and the lowest-ever body mass index was the main determinant of bone mineral density in patients with bulimia nervosa. CONCLUSION: In this study, many features of medical findings reported in anorexia nervosa were found in bulimia nervosa, however, the findings in bulimia nervosa were milder form than in anorexia nervosa. Management of any physical abnormalities in bulimia nervosa should focus on correction of the eating disorder.

BACKGROUND: Cruciate-retaining (CR) prostheses have been considered to produce more physiologic femoral rollback, provide better proprioception, and result in better quadriceps recovery than posterior-stabilized (PS) prostheses after total knee arthroplasty (TKA). However, there are very few studies demonstrating these benefits in an objective manner. We investigated whether CR-TKA could result in (1) better quadriceps recovery; (2) a greater proportion of patients with beyond the preoperative level of recovery; and (3) better clinical outcomes than PS-TKA. METHODS: This was a prospective non-randomized comparative study on the results of CR-TKA and PS-TKA. CR prostheses were used in 51 knees and PS prostheses in 51 knees. Quadriceps force was measured with a dynamometer preoperatively and at postoperative 6 weeks, 3 months, and 6 months consecutively. The Knee Society score (KSS) and range of motion (ROM) were also evaluated. RESULTS: There were no differences between two groups in terms of the objective quadriceps force during the follow-up period. The proportion of patients with beyond the preoperative level of recovery was similar between groups. Moreover, the KSS and ROM were not significantly different between two groups. CONCLUSIONS: CR-TKA did not result in better quadriceps recovery than PS-TKA during the 6-month follow-up. In other words, PS-TKA could lead to comparable quadriceps recovery despite greater preoperative weaknesses such as more restricted ROM and more severe degenerative changes of the knee.

BACKGROUND: Coronary arterioveonus fistula(CAVf) is a rare congerital coronary artery anomaly in adults. CAVF is related with some clinincal significances, such as angina, congestive heart failure and bacterial endocarditis. METHOD: We analyzed clincial characteristics in 10 patients(mean age=52.1 +/- 12.5 year) of adult CAVF, who were diagnosed as CAVF by coronary angiogram from Jan. 1993 to Mar. 1997 in Chonnam University Hosptial. RESULTS: Five out of 10 patients complained of chest pain, four had dyspnea and one had hemoptysis. In seven patients, arteries of CAVF were originated from left coronary arteries, from right coronary artery in one, and from both coronary arteries in two. CAVF was drained into pulmonary artery in six patients, right ventricle in two, right atrium in one, and left ventricle in one. CONCLUSION: Chest pain and dyspnea are common in symptomatic patients with CAVF are originated most commonly from left coronary arteries and drained into pulomonary arteries in Korean adults.

Venous angioma and cavernous angioma have its own distinctive characteristics in the pathological, radiological, and clinical points of view. However, the chances of coexistence of two disease entities as the neuroimaging techniques developed, and highlight the possibility made us suspect that they might share the same pathogenesis. When they coexist, the clinical symptoms are almost always caused by cavernous angioma. Here, we report 2 cases of cavernous angioma coexisting with a venous angioma in the posterior fossa presenting acute brainstem dysfunction.

Congenitally corrected transposition of the great arteries is a rate congenital heart disease. In this discase, there is discordance between both the atria and ventricles and the ventricles and great vessels. The anatomic left ventricle lies on the rightside and is connected to the pulmonic trunk, whereas the anatomic right ventricles lies on the left side and functions as the systemic ventricle. Most patients have associated another cardiac anomalies and conduction disturbance.Less commonly, ventricular extrasystoles, paroxismal supraventricular tachycardia, WPW preexitaion and atrial fibrillation may be obserced. We report an adult case of congenitally corrected transposition of great arteries associated with paroxysmal atrial fibrillation and heart failure.

BACKGROUND: The endovascular stent has been applied clinically in acute arterial occlusions after intimal dissection by angioplasty and in the prevention of restenosis. However, subacute stent thrombosis and restnosis remain major concerns in clinical stenting despite intravscular ultrasound guidance and high pressure inflation. Moreover, anticoagulation before and after stent implantation may be required for long periods and complicated by bleeding. A new strategy may be local drug delivery, which maintains sustained local concentration and may limit systemic complications. To evaluate the efficacy of local Nitric Oxide(NO) donor delivery on acute or subacute stent thrombosis and bleeding complications in patients, local NO donor delivery was performed in stented patients. METHOD: NO donor (2.0mg, Molsidomine) was delivered (1.0ml/min over 10min) using the Dispatch Catheter, after predilation of target lesion in 15 patients (8 angina, 7 myocardial infarction, mean age 5311.5 yr.) without heparin or nitrate infusion after stenting. After local NO donor delivery, Palmaz-Schatz stents were placed with standard methods. APTT and CK were checked at 1 hr, 3 hrs and 24 hrs after local NO donor delivery and STENTING. Follow-up coronary angiograms were done 48 hrs after stenting. RESULT: All patients had no hypotensive effects, no ischemic symptoms or no ECG changes during and after locaL NO donor delivery. ARTT and CK values were not changed at 3 and 24 hrs after local NO donor delivery and stenting. This allowed early arterial sheath removal. Follow-up coronary angiograms at 48 hrs showed all stents patent without stent recoil, with TIMI III flow, and without intra-stent thrombus. No target lesion revascularization and 100% event free survival were obsered for one month's clinical follow-up after NO donor delivery and stenting. Conclusion: Local NO donor delivery prior to stenting prevents acute and subacute stent thrombosis, systmic complications of nitrate, and maintains stent blood flow without stent recoil within the first one month after stenting.

BACKGROUND: Aspirin, one of the antiplatelet agents, improves the survival rate after myocardial infarction. This beneficial effect is known to be obtained in part by the antiarrhythmic action of aspirin. It is not known whether other antiplatelet agents have such effects. This study was performed to compare the effects of aspirin, ticlopidine, and abciximab (platelet glycoprotein IIb/IIIa receptor antagonist) on the ischemia-induced arrhythmias with a rat model of cardiac regional ischemia. METHODS: Experiments were performed in 4 groups of rats. The 4 groups were as follows : control, n=10:aspirin-pretreated, 300 mg/kg po for 1 week:ticlopidine-pretreated, 200 mg/kg po for 1 wk:abciximab-pretreated, 2 mg/kg iv 10-20 minutes before experiment. The electrocardiogram and blood pressure were recorded during 20 minutes. The time to the onset of ST-segment elevation and ventricular tachyarrhythmias, frequency and incidence of ventricular tachyarrhythmias, and death rate were assessed during acute myocardial ischemia induced by ligation of proximal left anterior descending coronary artery in anesthetized rats. RESULTS: Platelet aggregations to ADP were significantly lower in aspirin (42.8%), ticlopidine (43.8%), and abciximab group (34.0%) than in control group (66.4%). The frequencies of sustained ventricular tachycardia (VT) were 6.8+/-3.6 in control, 3.6+/-3.8 aspirin, 4.7+/-3.7 ticlopidine, and 1.4+/-2.5 abciximab group. The frequency of sustained VT in the abciximab group was significantly lower than in control group. The incidences of ventricular arrhythmias for 20 min were 10/10 for VT and 8/10 for ventricular fibrillation (VF) in control group, 7/10 for VT and 3/10 for VF in aspirin group, 10/10 for VT and 3/10 for VF in ticlopidine group, and 5/10 for VT and 4/10 for VF in abciximab group. The incidences of cardiac death during 20 min were 8/10 in control group, 4/10 in aspirin group, 2/10 in ticlopidine group and 5/10 in abciximab group. The incidence of VT in the abciximab group was significantly lower than in control group, incidences of VF in the aspirin and ticlopidine groups were significantly lower than in control group, and death rate in ticlopidine group was significantly lower than in control group. CONCLUSION: The present study suggested that aspirin, ticlopidine, and abciximab could prevent ventricular tachycardia or ventricular fibrillation in a rat model of cardiac regional ischemia and their antiarrhythmic effects improve the survival rate.
