Clin Exp Pediatr. 2006;49(5):513-518.   Published online May 15, 2006
Purpose : This study was undertaken to determine the differences in genotypes of rotavirus and their incidence between patients with acute rotaviral enteritis who suffered neurologic complications and those who did not suffer neurologic complications. Methods : Among the 82 patients with rotaviral enteritis whose genotype was analyzed, 71 patients were not associated with neurologic complications(neurology(－) group), and eleven patients were...

Purpose : Medicolegal problems start when the patient asserts the mistake of doctor and doctor does not accept it. The purpose of this study is to assess the actual condition of medicolegal problems and to provide solutions of medicolegal problems in the pediatric field.

Stenosis of Individual Pulmonary Veins
Mira Lee, Kil Soon Choi, Nam Su Kim, Myung Kul Yum, Yong Joo Kim, In Jun Sul
Clin Exp Pediatr. 2003;46(6):610-614.   Published online June 15, 2003
Pulmonary hypertension may be associated with variable conditions such as the hyperkinetic state or pulmonary vascular obstruction. In these, stenosis of the individual pulmonary veins without any cardiac or vascular malformation is very rare. We experienced stenosis of individual pulmonary veins in a 10 months old boy who was admitted with recurrent dyspnea and cyanosis and then underwent angiogram and...

Predicting of Aneurysm with Learning Vector Quantization in Patients with Kawasaki Disease
Jae Hyun Kwon, Myung Kul Yum, Nam Su Kim
Clin Exp Pediatr. 2000;43(1):78-84.   Published online January 15, 2000
Purpose : We applied Learning Vector Quantization(LVQ) in the analysis of data from Kawasaki disease patients with coronary artery aneurysm in an attempt to achieve accurate predictions of outcome for individual patients. Methods : One hundred and seventy-five patients with Kawasaki disease were recruited. First, data of 75 patients(of which 60 patients had no aneurysm and 15 patients had aneurysm) were trained using the network....
Development of Approximate Entropy of Fetal Heart Rate Varibility during Normal Pregnancy
Myung Kul Yum, Jung Hye Hwang, Moon Il Park
Clin Exp Pediatr. 1997;40(4):464-472.   Published online April 15, 1997
Purpose : The approximate entropy of heart rate variability has recently been used as a tool in evaluating cardiovascular health and physiology and in diagnosing pertubated physiologic status, by quantifying the irregularity and the pattern of the heart rate variability. Therefore approximate entropy of the fetal heart rate variability will be used as an important tool in studying the fetal...
Diagnosis and Treatment of Fetal Cardiac Anomalies
Nam Su Kim, Myung Kul Yum, Hahng Lee, Sung Ro Jung, Jung Bae Yoo, Jae Ek Lee
Clin Exp Pediatr. 1996;39(10):1395-1404.   Published online October 15, 1996
Purpose : Fetal echocardiography is used for the prenatal diagnosis of congenital heart disease. Fetal echocardiography allows decisions to be made in advance where the fetal abnormality is not compatible with life after delivery or where early correction is required. Our fetal echocardiographic experience was analysed retrospectively to guide future clinical application. Methods : 138 mothers had fetal echocardiography from April 1992 to December...
Comparative Study of Oscillation of Pulmonary Artery Pressure to That of Systemic Artery Pressure
Hyang Ok Woo, Hyung Jin Kwon, Myung Kul Yum
Clin Exp Pediatr. 1995;38(4):461-469.   Published online April 15, 1995
Purpose : The purpose of this study is to examine the difference between the below respiratory-frequency oscillations of the pulmonary artery pressure and those of the systemic arterial pressure. Methods : The subjects in this experiment were patients suffering from ventricular septal defect and having treatment with the cardiac catheterization at Gyeongsang National University Hospital. Signals from pulmonary...

Two Cases of Idiopathic Pulmonary Fibrosis
Young Gyun Oh, Seoung Hwan Kim, Mi Reong Kim, Byung Kiu Park, Hee-Shang Youn, Myung Kul Yum
Clin Exp Pediatr. 1992;35(1):122-128.   Published online January 15, 1992
Idiopathic pulmonary fibrosis is a heterogeneous group of disorder which predominantly affects the lung parenchyma and spares the airway. We report two cases of idiopathic pulmonary fibrosis in a 2 year 11 month-old female and a 1 year 1 month-old male patients who were treated with steroid. These patients presented with dyspnea and showed fine crepitant rales in both lung...

Studies on the Change of Pulmonary Artery Pressure in Early Neonatal Period.
Jung Ae Kim, Yung Kyun Oh, Byung Kiu Park, Hee Shang Youn, Myung Kul Yum
Clin Exp Pediatr. 1990;33(8):1081-1086.   Published online August 31, 1990
The change of postnatal pulmonary artery pressure was studied with doppler echocardiography and phonocardiogram in 40 normal full term neonates before 6 hours, between 6 〜 24 hours, 24~48 hours, 48-72 hours, 72 hours 〜 7 days. The results of study were as follows: Pc-To interval (sec) decreased (0. 071 ±0.002, 0.062±0.003, 0.050±0.002, 0.037±0.007, 0.027±0.003) and AT/ET ratio increased (0. 24±0.01, 0.30±0.02, 0.40±0.03, 0.40±0.04,...
A case of Henoch -Schönlein purpura associated with scarlet fever.
Hee Shang Yoon, Byung Kiu Park, Myung Kul Yum
Clin Exp Pediatr. 1989;32(11):1581-1585.   Published online November 30, 1989
We experienced an interesting case of Henoch-Schönlein purpura associated with scarlet fever in a 10-year-old girl. Typical two rashes representing Henoch-Schönlein purpura and scarlet fever appeared simultaneously. Fine erythematous maculopapular eruptions (goose-skin appearance) and straw-berry tongue, characteristic of scarlet fever, were present above the pelvis with varing sized purpuras, characteristic of Henoch-Schönlein purpura, below the pelvis.

To assess the VSD type of TOF and relationship between VSD type of TOF and pulmonary valve stenosis, small pulmonary valve annulus, and pulmonary artery anomaly, we analyzed 256 cases of surgically confirmed TOF patients. The summary of observation is as follows; 1) Four tytes of VSDs were found. The most frequent is perimembranous (PM) VSD of which incidence is 75.7% (159/210), second most...

Myung Kul Yum, Hye Sun Lee, Hee Sang Yoon, Yong Seung Hwang, Hyun Jip Kim
Clin Exp Pediatr. 1985;28(1):95-98.   Published online January 31, 1985
We reported a case of syringomyelia in a 9 year old boy. His major problem was left side hemiparesis and sensory loss. Diagnosis was made by myelography and spinal CT with the use of metrizamide, and was confirmed by surgical exploration. The hemiparesis and sensory loss improved after lamincetomy and decompression.
