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.

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.

OBJECTIVE: To compare the age of menarche, changing patterns of the menstrual characteristics in adolescent girls between 1988 and 1998. METHODS: A survey was undertaken for 1,500 highschool girls and compare with those of pervious study for 5,000 middle and highschool girls performed by same author in 1998 by means of questionnaire. RESULTS: During a decade, the mean menarcheal age decreased from 13.5+/-1.0 to 12.7+/-1.0 years(p=0.001). Gynecologic age, Body mass index were associated with age of menarche in both 1988 and 1998. The interval of menstruation was 30.6 3.5dyas in 1998 and shortened compared with 32.1+/-6.3 days in 1988(p=0.001). The duration of menstruation was lengthened in 1998 than in 1988(6.1+/-1.1 days vs 5.8+/-2.2 days, p=0.001). The incidence of irregular cycle(28.2% vs 58.2%, p=0.001), dysmenorrhea(73.9% vs 77.8%, p=0.001), and secondary amenorrhea(16.2% vs 27.2%, p= 0.001) decreased in 1998 compared with those of 1988. The incidence of agonies about menstruation was also decreased in 1998 than in 1988(26.2% vs 69.1%, p=0.001). The most common agony about menstruation in 1988 was irregular cycle(28.4%), but dysmenorrhea( 64.3%) in 1998. CONCLUSIONS: From the above results, the mean age of menarche was advanced since last decade but most of the adolescent girls still have suffered from dysmenorrhea.

To validate the diagnostic significance of red cell indices in non-anemic iron deficiency and iron deficiency anemia, complete blood count, serum iron, total iron binding capacity, and serum ferritin were measured in 208 middle school girls between 13 and 15 years of age. We used Reciever Operatin Characteristic (ROC) curve to compare the diagnostic significances of various red cell indices (MCV, MCH, MCHC, RDW). We also established the ideal cutoff values of red cell indices for the diagnosis of iron deficiency anemia. The results were as follows: 1) The prevalence of iron deficiency anemia and non-anemic iron deficiency were 4.8% and 11.1% respectively. 2) For the diagnosis of iron deficiency anemia, MCV had the highest diagnostic capacity, and MCH was the secondly useful one. 3) For the diagnosis of non-anemic iron deficiency. MCV had the highest diagnostic capacity, but the sensitivity and specificity of the 4 red cell indices(MCV, MCH, MCHC, RDW) were so low that they could not be used as screening or confirmative tests. 4) The sensitivity and specificity of MCV were 1 for the diagnosis of iron deficiency anemia(cutoff value: MCV=79 fl). In case of MCH, the sensitivity was. 1 and the specificity was 0.995 for the diagnosis of iron deficiency anemia(cutoff value: MCH=25pg). In case of MCHC, the sensitivity was 1 and the specificity was 0.69 for the diagnosis of iron deficiency anemia (cutoff value: MCH-33g/dl). In case of RDW, the sencitivity was 0.9 and the specificity was 0.96 for the diagnosis of iron deficiency anemia(cutoff value: RDW=13.5%). With above results, we could conclude that MCV and MCH were very useful screening tests for iron deficiency anemia and MCV could be used as a confirmative test of iron deficiency anemin.
