We studied the angiographic findings in 65 patients wtih congenital pulmonary atresia, ages 4 days to 14 years(mean 3.3 yrs), form 1981 to 1986 at Severance Hospital Yonsei University. 1. 6 had pulmonary atresia with anintact interventricular septum, 38 had it with cardiac anomaly Renodynamically simulating TOF, and 21 associatedwith more complicated cardiac anomalies. 2. In the group with an intact ventricular septum, 5 showed confluentintrapericardial pulmonary artery, all segmental pulmonary arteries connceted to intrapericardial pulmoanryartery. 3. In the group simulating TOF, aorta arose from RV with or without overriding in 35. In 27 patients withconfluent intrapericardial pulmonary artery, 23 had more than 10 segmental pulmoanry arteries connceted tointrapericardial artery and 5 had severely hypoplastic hilar pulmonary arteries. In 11 with nonconfluentintrapericardial pulmonary artery, 4 had more than 10 segmental pulmonary arteries connected to central pulmonaryartery and 9 had severely hypoplastic hilar pulmonary arteries. 4. In the group associated with more complicatedcardiac anomaly, included 8 patients with atrioventricular discordance, 7 with univentricular heart and 6 withtricuspid atresia. In 17 patients with confluent intrapericardial artery, 16 had more than 10 segmental pulmoanryarteries conncected to intrapeircardial artery, one showed severe hypoplasia of hilar pulmonary arteries. Inanother 4 with nonconfluence, no one showed more than 10 segmental arteries conncted to intraperdicardial or hilarpulmonary artery.

Chondromalacia patella is a symptom complex characterized by aching pain behind the knee cap, retropatella tenderness that is aggravated by the stair climbing. Malalignment is an important factor causing chondromalacia patella. And to recognize it, is important in the diagnosis and treatment. We studied 3 parameters in the chondromalacic knee and nonchondromalacic knee and the following results was obtained. l. In nonchondromalacic knee, the sulcus angle is 141° 7′ and the congruence angle is −5° 1′ 2. In chonduomalacic knee the sulcus sagle is 139° 2′ and the congruence angle is +5° 3′ 3. In the group with abnormal congruence angle, there was much degenerative changes in the patellofemaral joint. So, it can be inferred that chondromalacia is a precursor of the osteoarthritis and the patient with abnormal congruence angle should be treated actively at the early stage if the conservative treatment had failed.

This is a report of 13 cases of surgically corrected ruptured aneurysm of the aortic sinus of Valsaha. The simultaneous trans-venous and trans-arterial catheterization and cineangiogram are the best diagnostic procedures. In 12 cases, the aneurysm originated from the right coronary sinus and only one from the noncoronary sinus. Eleven aneurysms ruptured into the right ventricle and 2 into the right atrium. Eight cases were associated with ventricular septa1 defect and 5 with aortic regurgitation. In three cases the Hancock porcine valve replacement was done. There was no surgical mortality.

Pulmonary vein stenosis is a rare condition which is usually congenital in origin and is almost invariably fatal in its bilateral and severe forms. It is often overlooked, however, during clinical examination, routine echocardiography, and even at cardiac catheterization. This report describes pulsed Doppler, color flow echocardiography, and hemodynamic findings of bilateral pulmonary vein stenosis accompanying ventricular septal and atrial septal defects successfully corrected by surgery.

Twenty-one patients undergoing aortic valve replacement for pure aoritic regurgitation were studied retrospectively to evaluate the left ventricular function and internal dimension change before, 1-6 weeks(early postoperative) and 2-36 months after(late postoperative) aortic valve replacement by serial echocardiography. Postoperatively, NYHA function class improved remarkably (from 3.3+/-0.6 to 1.4+/-0.7). Early postoperatively, left ventricular end-diastolic dimension (EDD), left ventricular end-systolic dimension(ESD), left ventricular fractional shortenting(FS) significantly decreased in all patients(7.6+/-1.2cm vs 5.8+/-1.5cm P<0.001, 5.5+/-1.3cm vs 4.7+/-1.3cm P<0.001, 39+/-12% vs20+/-8% P<0.001 respectively). Interventricular septum thickness(IVS) and posterior wall thickness (PW) were slightly thickened before(1.4+/-0.3cm, 1.3+/-0.3cm respectively) and in the early postoperative period (1.3+/-0.4cm, 1.3+/-0.3cm respectively) without significant interval change. Late postoperatively, EDD and ESD decreased significantly (7.8+/-1.2cm vs 5.1+/-0.8cm P<0.01, 5.1+/-1.1cm vs 3.4+/-0.8cm P<0.001. respectively), and FS increased significantly (25+/-9% vs 34+/-9%, P<0.05). Among 3 patients of so called high risk group mentioned by Henry(22,33), ESD and FS improved to normal range in 2 patients, and ESD decreased to 4.4cm and FS increased to 33% in the other one. EDD and ESD decreased significantly in both group I(preoperative ESD<5.5cm) and group II(preoperative ESD<5.5cm), without no decrement difference between two groups, and there was a significant difference of FS decrement between group I and group II at early postoperative period. Preoperative ESD correlated highly with the early postoperative EDD(r=0.89) and ESD(r=0.87) with statistical significance, and moderately high with late postoperative EDD(r=0.45), ESD(r=0.50) and FS(r=0.42) without statistical signiticance. We concluded that there was significant improvement in left ventricular function in pure aortic regurgitation patients postoperatively. Preoperative left ventricular and systolic dimension above 5.5cm and fractional shortenting below 25% are not so reliabel index of poor postoperative prognosis.

Since the first report on infective endocarditis by Rokitansky in 1985, this subject has been extensively dealt with in the world literature. Nowadays by use of echocardiography, there has been a high discovery rate of vegetation, and thus made it a valuable tool in diagnosis, treatment, and the evaluation of the patient. However in Korea, there have been only a few case reports and even fewer studies on infective endocarditis. This study is a clinical analysis of 87 infective endocarditis cases, which were admitted and treated at the department of Pediatrics and Internal medicine, diagnosed as infective endocarditis, during the period from january 1975 through February 1984. 1) The mean age was 24.8 years and male to female ratio was 1.49:1. 2) Annual incidence showed no increment during the period and it was 1:2500. 3) Underlying heart diseases consisted of rheumatic heart disease(52.3%), congenital heart disease(39.7%), no underlying heart disease(8%), previous infective endocarditis(4.6%), and prosthetic valve endocarditis(3.4%). 4) Frequent clinical manifestations on admission were high fever, heart murmur, congestive heart failure and frequent laboratory findings were positive blood culture results, anemia, positive C-reactive protein, and hematuria. 5) Blood culture was positive in 75.9% and the most common infecting organism was alpha-streptococcus, which represented 42.4% of total positive cases. S. aureus and S. epidermidis were next common and these three organisms consisted of 71.2% Culture positivity was not significantly related to the type and incidence of complications. 6) Antibiotics sensitivity of the major isolated organisms were performed. Alpha-streptococcus was sensitive to almost all antibiotics except Tetracycline. Group D-streptococcus was sensitive to Chloramphenicol and Cephalosporin. S. aureus and S. epidermidis showed same results, which showd sensitivity to Chloramphenicol, Cephalosporin and Methicillin and resistence to penicillin. 7) Echocardiography was performed in 55 cases and showed vegetation in 58.2%. Complications related to the echocardiographic identification of the vegetations showed difference only in the mortality rate, which was greater by 3 times in the positive cases than in the negative. 8) Peripheral embolizations occurred in 29.9% of cases, and by far the mostcommon site was the brain, where 63% of the embolism was localized. 9) Sufficient duration of hospitalization(4-6 weeks) and judicious antibiotics administration was done in 43.7%. The initial response to therapy was noted in 48.5% of total febrile cases. 10) The mortality rate of the cases was 13.8% of the patients died. However, as many patients were discharged against advice because of socio-economic factors, precise therapeutic results of these cases could not be obtained.

Surgical revascularization is very effective for the relief of chest pain, improvement of exercise tolerance and ventricular performance in certain ischemic heart diseases. Bypass graft angiography and native coronary angiography after coronary artery bypass graft(CABG) were required for the evaluation of graft patency, progression of the native coronary artery disease and to predict the prognosis of the patients after CABG. The cases included in this study involved 15 patients who underwent selective bypass graft angiography among 102 CABG cases. Thirty eight sites were bypassed by saphenous vein and two sites by internal mammary artery. The results were as follows: 1) The overall patency rate of the saphenous vein bypass graft was 76.3% and the two sites of the internal mammary artery bypass graft were both patent. 2) The patency rate of direct anastomosis was 86.2% and of sequential anastomosis, 44.4%. 3) In eight patients who underwent native coronary angiography, five patients showed progression of grafted coronary artery disease. Among them, two patients had accompanying progression of coronary artery disease in non-grafted vessels. 4) Follow up treadmill test performed in six patients showed improvement of exercise tolerance in all patients. 5) There was some increase in the ejection fraction of the left ventricle after CABG in six patients who received follow up left ventriculography.

Surgical treatment of compressive ulnar neuropathy at the elbow has been performed with a wide variety of techniques. Among these techniques, anterior submuscular transposition of the ulnar nerve has been regarded as the method of choice by many authors. It has many advantages including a low recurrence rate, scar-free vascular bed, and protection from repeated trauma to the nerve. However, anterior submuscular transposition is technically demanding and requires more extensive soft tissue dissection. On the other hand, anterior subfascial transposition is less invasive, requires a relatively shorter operation time than the submuscular technique, and also can be done safely even in patiensts with elbow arthritis. We evaluated the clinical results of anterior submuscular transposition compared with anterior subfascial transposition. Fifteen patients underwent anterior submuscular transposition and ten patients underwent anterior subfascial transposition of the ulnar nerve. The mean follow-up time was 15 months (range 10 to 38 months) in the anterior submuscular transposition group and 7 months (range 6 to 15 months) in the anterior subfascial transposition group. According to the outcome status determination algorithm devised by Mowlavi, 3 patients (20%) showed total relief, 10 patiensts (66.7%) improvement and 2 patients (13.3%) no changes in the anterior submuscular transposition group. In the anterior subfascial transposition group, 2 patients (20%) showed total relief, 7 patients (70%) improvement and 1 patient (10%) displayed no changes. Statistically there was no significant difference of the clinical results between the two surgical techniques. Therefore we would suggest anterior subfascial transposition of the ulnar nerve as a preferred method for treatment of cubital tunnel syndrome.

OBJECTIVES: Research into emotional or behavioral stress typically focuses upon the hypothalamic-pituitary-adrenal axis. It is well established that the hypothalamic-pituitary-adrenocortical axis is subject to inhibitory control by opioids in a variety of animal species including pigs. Exposure to acute stress induces the upregulation of opioid receptors and the release of endogenous peptides which mediate the stress-induced analgesia. There is some literature substantiating that repeated stress can lead to changes in opioidergic neurotransmission. However, the changes are highly variable. This study was designed to observe the modulatory effect of repeated immobilization stress on opioidergic neurotransmission. METHODS: Male Sprague-Dawley rats weighing 150-200g were forced to suffer immobilization stress for 2 hours on each of 14 successive days. Then we examined the maximum binding capacity and affinity of each opioid subtypes(mu, delta, kappa). RESULTS: Repeated immobilization stress increased the binding of [3H]DPDPE on the delta-subtype opioid receptor in the striatum and hypothalamus. Saturation experiments followed by scatchard analyses of the results showed an increase in the density of delta-subtype opioid receptors, but the affinity of the delta-subtype opioid receptor remained unchanged. Repeated immobilization stress reduced enkephalin activity of striatum and hypothalamus. CONCLUSIONS: From these results, it could be concluded that repeated immobilization stress up-regulated the delta-subtype opioid receptors and reduced the activity of enkephalin, an endogenous ligand for the delta-subtype opioid receptor.
