Dysplasia epiphysealis multiplex is a rare syndrome, first discribed by Fairbank in 1935, but numerous publications have made it a well-recognized entity. The syndrome is caused by a congenital developmental error of unknown etiology, characterized by changes in the developing epiphyses, dwarfism and stubby digits in children of normal intelligence. Diagnosis is mainly by roentgenographic apperences of the epiphyses before fusion to the shaft. The centers of ossification of the epiphyses are late in appearing, slow in developing, deformed in shape and irregular in density. The spine is never affected, blood and biochemicaI studies show no abnormality. A case of dysplasia epiphysealis multiplex which revealed typical roentgenographic pictures is presented with a brief review of a literature.

One hundred and sixty five cases of the fracture of tibial shaft in adult have been treated and managed in the Department of Orthopedic Surgery, Kyunghook National University Hospital during the period from January, 1965 to December, 1970. Seventy one of 165 patients were analyzed clinically and we came to the following conclusions. 1. Most of the injuries were the results of traffic accident (67.6%). 2. The incidence of trauma was high in the young man, most frequent in the 3rd decade. 3. The closed fractures were three times more than open fractures and the middle third of tibial shaft was the most frequent site of fracture. 4. The average healing period was 16 weeks in mild case and 28 weeks in severe case. 5. Of 71 cases, we experienced 4 cases of non-union, 8 cases of residual joint stiffness at the knee and the ankle and 3 cases of leg shortening (more than 2 cm.) as complication.

PURPOSE: To find the rebleeding factors in bronchial arterial embolization for treatment of hemoptysis, a retrospective study was performed. MATERIALS AND METHODS:Medical records, anglographic findings and embolic materials of 35 patients who had undertaken arterial embolization for control of hemoptysis were reviewed. The period of follow-up for rebleeding was from 3 to 32 months after arterial embolization. We investigated the anglographic findings of extravasation, neovascularity, intervascular shunt, aneurysm and periarterial diffusion. Neovascularity was classified as mild(numerable neovascularity) and severe(innumerable). RESULTS: Rebleeding occured in 15(43%) among 35 cases. Only two of 11 cases with no past episode of hemoptysis showed recurrence, while 9 of 15 cases who had more than three episodes did. Severe neovascularity were seen in 11 of 15 recurred cases, but seven of 20 non-recurred cases showed severe neovascularity. More than three anglographic findings representing hemoptysis were seen on 11(73%) among recurred 15 cases and seven(35%) among non-recurred 20 cases. The lesion was supplied by more than two different arteries on 8(54%) of the recurred cases, but only three(15%) of the non-recurred cases. Six of seven cases persistent neovascularity after arterial embolization were recurred. CONCLUSION: The history of repeated hemoptysis, severe neovascularity, variable anglographic findings, and post-embolization persistency of neovascularity were the factors related with the rebleeding after arterial embolization for hemoptysis. Careful and active arterial embolization are required on these conditions.

To investigate frequency of painful and/or silent myocardial ischemia(SMI) determined by ECG ST-segment depression(more than 1.0mm depression for 0.08 second after J point over 60 seconds) during unrestricted daily activities, 24-hour dynamic ECG was performed in 19 patients(11 males, 8 females) with chronic stable angina pectoris, aged 57.4 years(44 to 73 years). During 456 hours of recording, there were 154 episodes of SMI. Of these, 139 episodes(90.3%) were silent and 15 episodes(9.7%) accompaned chest pain. The higher incidence of SMI than previously published data is probably influenced by 1 patient who disclosed 56 episodes (excluding this, SMI 84.7%). Sixty one percent of episodes of SMI occurred during light activities such as slow walk, hand labor, eating or at rest(sitting at ease), smoking and sleep, and 39% during more strenuous activites such as walk, climbing stairs and physical exercise. In contrast, most of the painful myocardial ischemia(PMI) developed during climbing stairs, walk and physical exercise. Heart rate during episodes of SMI varied ranging from 85.2+/-13.7/min at rest to 115.5+/-19.2/ min druing climbing stairs. Mean ST-segment depressions during episodes of SMI and PMI were 2.0(1.0-4.0)mm and 2.6(1.2-7.0)mm, respectively, in 6 patients who disclosed both SMI and PMI on 24-hour ECG recordings. However, frequency of ischemic episodes was higher(9.0 vs 2.5/day) and duration was longer(13.8min vs 3.0min) in SMI. These findings indicate that transient SMI in patients with chronic stable angina pectoris occurs more frequently than painful myocardial ischemia. In addition, SMI develops during activities that increase heart rate(increased O2 demand) as well as during activites that do not increase heart rate(decreased O2 supply). Therefore, both O2 demand and supply mechanisms may be involved in the pathogenesis of transient SMI in Patients with chronic stable angina pectoris.

This study was undertaken to determine the adequate bracket slot torque degrees in Korean. The subjects were consisted of plaster casts of 30 male and 30 female. They had acceptable profile, normal occlusion, no loss of tooth and no experience of dental treatment. Labiohngual or buccolingual inclinations of individual tooth were estimated as +, - degrees on the fixed model by use of dental surveyor, contact angle gauge and measuring grid. The following conclusions were obtained 1. Adequate degrees of bracket slot torque in Korean were obtained. 2. The degrees of labiolingual or buccolingual inclination of every tooth were very variable according to the individuals. 3. Almost constant torque degrees were observed on the maxillary buccal segments. 4. Progressive increase in minus torque degrees were observed from the mandibular canines to the 2nd molars.

BACKGROUND: The two most commonly used drugs as a stressor during wtress echocardiography are dipyridamole and dobutamine. The purpose of this study was to compare diagnostic accuracies of dipyridamole and dobutamine stress echocardiography for fixed coronary artery disease and evaluate complications related to the two agents in the same patients. METHODS: 30(M : 5=19 : 11, age=56+/-8.8yr) consecutive patients without history of previous myocardial infarction underwent coronary angiography, dipyridamole and dobutamine stress echocardiography in random order. Dipyridamole was infused up to 0.84mg/Kg for 10 minutes during clinical, ECG and echocardiographic montioring. Dobutamine was infused in dose increments from 5 to 40microg/Kg/min under the same condition. Positive criteria for myocardial ischemia by echocardiography was now regional wall mation abnormatity or worsening of regional wall motion after stress. Significant coronary disease was defined as more than 70% stenosis by coronary angiography. RESULTS: The sensitivity and specificity of both stress echocardiography were same, 82% and 92% respectively. In a single vessel disease the sensitivity of dipyridamole echocardiography was 75% and dobutamine echocardiography was 83% without statistical difference. The correlation of ischemic free time during both stress test was 0.375. During dipyridamole infusion no test was prematurely terminated because of side effects, but 3 patients(10%) developed severe hypertension and ventricular arrytricular arrythmia during dobutamine infusion and test was terminated. CONCLUSION: Thus, by this prospective direct comparison of both stress test, dipyridamole and dobutamine stress echocardiography have similar diagnostic accuracies for the detection of coronary artery disease. But during dobutamine infusion, careful monitoring for hemodynamic changes arrythmia is required for possible serious complications.

To assess the efficacy of amiodarone on chronic atral fibrillation(AF) and to evaluate the relation between the ability to convert AF to sinus rhythm (SR) with amiodarone therapy and left atrial(LA) size and atrial fibrillatory wave forms, 22 patients with AF, aged 40 to 60 years(mean 47.5 years), were studied. Nine patients(40.9%) had mitral valvaular heart disease, 6(27.3%) hypertension, 5(18.2%) lone AF and 2 (9.1%) cadiomyopathy. Amiodarone therapy with either 600mg for 1 week, 200mg for 4 weeks in 5 consecutive patients, or 800mg for 1 week, 400mg for 4 weeks and 200mg for 6 weeks in 17 patients, converted AF to SR in 9(40.9%) patients 3 to 6 weeks after amiodarone was started on. In either group, patients who achieved conversion had smaller LA size(mean 43.7mm) than those who failed conversion(mean50.2mm)(P<0.05). Those who had LA size less than 45mm achieved conversion of AF to SR in 70%, comparing to 16.7% in patients with LA size more than 46mm(P<0.05). Among patients who achieved conversion, LA size was less than 46mm in 77.8% comparing to 23.1% in patients who failed conversion on Amiodarone. Those with coarse AF(46.2mm), althogh the difference was not significant statistically. There was no converstion in patients with LA size greater then 58mm and in patients with coarse AF who concomittantly had MVD. These findings suggest that the efficacy of amiodarone was related to LA size, and to the atrial fibrillation wave form in patients with mitral valvular heart disease.
