Thirty-six cases of paroxysmal supraventricular tachycardia which were observed at the Department of Pediatrics, Seoul National University Hospital from 1976 till October 1982, were analyzed. 1. The sex ratio was 1.8:1, male predominance. Sixteen cases (44.4%) were under 1 year of age and 11 cases (30.6%) were under 4 months of age. 2. Cases without known heart disease were 22(61.6%). Among Known etiology, most frequent one was 7 cases(19.4%) of W-P-W syndrome. 3. The sex ratio of group without known heart disease was 2.1:1, and that of group with known heart disease was 1.3:1. Under 4 months of age, there were more cases without known heart disease(72.7%) and after 4 months of age number of cases with and without known heart disease were similar. 4. Most frequent clinical manifestation was tachydyspnea. hepatomegly, irritability, palipitation, cyanosis and pallor, vomiting, chest pain, edema, abdominal pain, and fever were followed in order of frequency. 5. Congestive heart failure occurred in 22 cases(61%). The incidence was related to the duration of attack of tachycardia, age of patients, and heart rate. The longer the duration of attack and the younger the age of patients and the faster the heart rate, the higher incidence of heart failure was observed. 6. As treatment, vagal reflex stimulation was almost ineffective, and digitalization was effective in most of the cases. Verapamil and electrical cardioversion were tried in small number of cases and proved to be effective. 7. One case (2.8%) expired becase of the supraventricular tachycardia. 8. Eight cases (30.8%) had recurrence. In younger age group, recurrence rate was lower. 9. Digoxin was given in 15 cases for prevention of recurrence and was effective in 12 cases.

The head injuried patient with skeletal trauma is a challege to the orthopedic surgeon. The orthopedist initially may face the difficult management of fracture and dislocation in the patient associated with head injury. The management of the injuries to the head takes precedence over extremity injuries initially, but the orthopedist must be managed aggresively with assumption that full neurologic recovery will occur. This report analysed the treatment and results in 85 cases fracture and dislocation with head injury among the 59 patients at the Chungnam National University Hospital during the period ranging from March, 1980 to March, 1983. End result obtained are as follows: 1. The sex ratio between the male and female was 3.9: 1 and the prevalent age distribution was from 21 to 30 years of age. 2. The motorcycle accident was most common cause of the trauma and the next most frequent one was the automobile accident. 3. Type of head injury were contusion or concussion, intracranial hemorrhage, linear skull fracture, depressed skull fracture and open skull fracture. 4. Better result were obtained by operative treatment in femur fracture, especially spastic group. 5. The incidence of delayed diagnosis was 8 cases and the delay in diagnosis ranged from 15 to 95 days with an average of 38 days. 6. We, consulting with neurosurgeon, must assume that full neurologic recovery will take place and so open reduction and internal fixation should be carried out as quickly as possible.

Zonisamide was administered to 20 patients with refractory epileptic seizures. The mean duration of the administration was 6 months, and the mean dosage was 7.2 mg/kg/day. The efficacy of zonisamide was rated remarkable in 15% of the cases, improvement in 40%, and no change in 45%. The response rates of zonisamide were 62.5% for myoclonic seizures, 50% for tonic-clonic seizures, 80% for atonic seizures and 33.3% for atypical absence seizures. There was no correlation between the clinical response and dose or serum concentration of the drug. The adverse effects were observed in 35% of the cases which were drowsiness, dizziness, ataxia, nausea, and vomiting. In all cases, however, the administration of zonisamide could be continued.

BACKGROUND: Recently-developed equipment based on bioelectrical impedance analysis (BIA) not only measures total body fat but also displays several estimated indicators that reflect intra-abdominal fat, such as waist circumference (WC) and waist-to-hip ratio (WHR). This study examined the usefulness of these indicators in the diagnosis of metabolic syndrome (MS). METHODS: A total of 632 people over 20 years of age (355 men and 277 women, mean age 48.61+/-11.08 years, mean BMI 23.62+/-3.00 kg/m2, 117 MS patients) were enrolled in the study. Measurements of WC and hip circumference were measured by one individual, and WHR was calculated. BIA was performed to estimate waist circumference (BIAWC) and waist-to-hip ratio (BIAWHR). Receiver operating characteristic (ROC) curve analysis was used to examine the usefulness of BIAWC and BIAWHR in diagnosing MS. RESULTS: The areas under the curve (AUCs) were 0.836 (95% CI 0.805-0.864) for WC, 0.814 (95% CI 0.782-0.844) for BIAWC, 0.815 (95% CI 0.782-0.844) for WHR, and 0.805 (95% CI 0.772-0.835) for BIAWHR. The difference between the AUCs of WC and BIAWC (0.022, 95% CI -0.004 to 0.048) and the difference between the AUCs of WHR and BIAWHR (0.010, 95% CI -0.015 to 0.034) were not significant. CONCLUSIONS: The indices for central obesity estimated by BIA had high agreement with the direct method, and they were not inferior to direct measured indices for predicting metabolic syndrome.

The myocardial infarction is usually associated with the coronary artery disease in adults. It is unusual in chilhood and young adult but occasionally associated with coronary vasculitis. Takayasu's arteritis produces a panaortits with thickening of the adventitia and narrowing of aorta. Narrowing of coronary arteries is due to extension into these arteries of the processes of inflammation that occur in aorta. We report here two cases of Takayasu's aortitis causing acute myocardial infarction. Case 1 is a 17-year-old girl presented with the inferior myocardial infarction and the cerebral infarction. Digital subtraction aortography showed a diffuse narrowing of the aorta and the obstruction of both subclavian arteritis, right carotid artery and both femoral arteries. Case 2 is a 19-year-old male patient with anterior myocardial infarction. Coronary cineangiogram showed the beak like appearance of the left main coronay artery.
