In the rapidly changing environmental situation during the coronavirus disease 2019 outbreak, neonatal centers have developed telemedicine systems with extended coverage for neonatal monitoring and high-risk follow-up programs including neonatal hyperbilirubinemia. At this point, electronic health technology and noncontact medical system increase the effectiveness of rather than replacing the face-to-face visit and the opinions of experienced neonatologists.

Genetic risk factors associated with respiratory distress syndrome
Heui Seung Jo
Clin Exp Pediatr. 2014;57(4):157-163.   Published online April 30, 2014

Respiratory distress syndrome (RDS) among preterm infants is typically due to a quantitative deficiency of pulmonary surfactant. Aside from the degree of prematurity, diverse environmental and genetic factors can affect the development of RDS. The variance of the risk of RDS in various races/ethnicities or monozygotic/dizygotic twins has suggested genetic influences on this disorder. So far, several specific mutations in...

The Effect of Histologic Chorioamnionitis on the Development of Respiratory Distress Syndrome and Chronic Lung Disease in Preterm Infants
Heui seung Jo, Beyong Il Kim, Chang Won Choi, Jun Dong Park, Chong Jai Kim, Jung-Hwan Choi
Clin Exp Pediatr. 2004;47(2):150-156.   Published online February 15, 2004

Purpose: Histologic chorioamnionitis may play a role in the development of respiratory distress syndrome(RDS) and chronic lung disease(CLD) independently or through its association with preterm birth. We investigated the relationship between histologic chorioamnionitis and clinical complications including, RDS and CLD, of preterm infants. Methods: Clinical data were collected retrospectively from 478 preterm infants(gestational period≤34 weeks) who were admitted to the neonatal...

A Case of Citrullinemia Diagnosed at the Neonatal Period
Seung Kyu Song, Kyung Chang Oh, Mi Ae Hong, Hee Taeg Kim, Hye Jung Shin, Soon Young Kim, Jin Keun Chang, Heui Seung Jo, Beyong Il Kim, Sei Won Yang, Jung-Hwan Choi

Citrullinemia is a rare inborn error of metabolism of the urea cycle, and was first reported by McMurray, et al. in 1962. It is inherited as an autosomal recessive trait. The normal synthesis of argininosuccinic acid is blocked in this disease due to a deficiency of argininosuccinic acid synthetase(AS), which has been demonstrated in liver cells and fibroblasts. The clinical...

Classification and Risk Factors for Chronic Lung Disease(CLD) of Prematurity : Classical CLD Versus Atypical CLD
Chang Won Choi, Beyong Il Kim, Heui Seung Jo, Jun Dong Park, Chong Jae Kim, Bo Hyun Yoon, Jung-Hwan Choi
Clin Exp Pediatr. 2001;44(11):1222-1232.   Published online November 15, 2001
Purpose : We tried to classify the different type of CLD and assess the risk factors for classical CLD and atypical CLD. Methods : Retrospective cohort analysis was done in 120 preterm infants with birth weights less than 1,500 g who were admitted to NICU in Seoul National University Children's Hospital between Jan. 1993 and Dec. 1998 and survived more...

A Case of Congenital Methemoglobinemia Due to NADH-Methemoglobin Reductase Deficiency
Do Hyeon Kim, Jin A Lee, Sung Jae Lee, Heui Seung Jo, Yun Kyoung Lee, June Dong Park, Beyong Il Kim, Jung-Hwan Choi, Dong Soon Lee, Han Ik Cho, Kyung Ran Park
Clin Exp Pediatr. 2001;44(6):699-704.   Published online June 15, 2001
Congenital methemoglobinemia is caused by NADH-methemoglobin reductase deficiency in more than half of the total reported cases. NADH-methemoglobin reductase deficiency is an uncommon hereditary disorder producing methemoglobinemia and cyanosis in the homozygous subject. A majority of the patients born with these abnormalities have only a cosmetic defect-asymptomatic cyanosis. Congenital methemoglobinemia due to NADH-methemoglobin reductase deficiency is an autosomal recessive disorder...

Effects of Cisapride on QTc Interval and QT Dispersion in Preterm Infants
Heui Seung Jo, Chang Won Choi, Yun Kyung Lee, Hee Seok Kim, Jun Dong Park, Jun Huh, Beyong Il Kim, Chung Il Noh, Jung-Hwan Choi
Clin Exp Pediatr. 2000;43(2):188-194.   Published online February 15, 2000
Purpose : Cisapride, a prokinetic agent, is widely used in preterm infants with feeding intolerance or gastroesophageal reflux. Although cisapride is regarded as a safe drug, increased QTc interval or ventricular arrhythmia has been reported in adults and neonates. So we prospectively examined the effects of cisapride on the QTc interval and QT dispersion in preterm infants. Methods : QTc interval...
