Clin Exp Pediatr. 2019;62(4):131-137.   Published online October 23, 2018

Purpose: Respiratory syncytial virus (RSV) infection can cause various neurological complications. This study aimed to investigate the RSV-associated neurologic manifestations that present with seizures. Methods: We retrospectively reviewed the medical records of patients aged less than 15 years with laboratory-confirmed RSV infections and seizures between January 2011 and December 2016 in a regional hospital in South Korea. Results: During this period, 1,193...

Clin Exp Pediatr. 2016;59(2):91-95.   Published online February 29, 2016

We report the case of a 22-month-old boy with a new mosaic partial unbalanced translocation of 1q and 18q. The patient was referred to our Pediatric Department for developmental delay. He showed mild facial dysmorphism, physical growth retardation, a hearing disability, and had a history of patent ductus arteriosus. White matter abnormality on brain magnetic resonance images was also noted....

Characteristics of allergic pollens and the recent increase of sensitization rate to weed pollen in childhood in Korea
Jae-Won Oh
Clin Exp Pediatr. 2008;51(4):355-361.   Published online April 15, 2008
Pollen is very important causing factor for allergy such as allergic rhinitis, allergic conjunctivitis, and asthma, and pollen allergy has a remarkable clinical impact all over Korea. The main pollination period covers about half the year, from spring to autumn, and the distribution of airborne pollen taxa of allergological interest is related to pollen season dynamics. Korean academy of pediatric...

Ultrastructure of nasal cilia in children with recurrent or persistent respiratory diseases
Su-A Shin, Seung Yang, Jae-Won Oh, Ha-Baik Lee, Cheol-Eon Park, Jung-Kyun Kwan
Clin Exp Pediatr. 2006;49(4):410-416.   Published online April 15, 2006
Purpose : Ciliary abnormalities of the respiratory system usually accompany recurrent or persistent respiratory diseases such as paranasal sinusitis, bronchiectasis, rhinitis, and/or otitis media, since they cause certain derangements in ciliary cleaning activities. This disease is usually inherited by autosomal recessive trait, but may also be found to be acquired or transient in rare cases after heavy exposure to pollutants,...
A Clinical Study of Neurologic Abnormalities Associated with Rotavirus Gastroenteritis
Yoon-Duk Kang, Myung-Kul Yum, Jae-Won Oh, Chang-Ryul Kim, In-Joon Seol, Jung-Oak Kang
Clin Exp Pediatr. 2004;47(7):751-755.   Published online July 15, 2004
Purpose : Reports of neurologic abnormalities associated with acute diarrhea are increasing recently. It was reported that the incidence of the neurologic abnormalities related to gastroenteritis was higher in rotavirus gastroenteritis than in non-rotavirus gastroenteritis. We investigated the incidence, the manifestations and the prognosis of the neurologic abnormalities associated with rotavirus diarrhea and non-rotavirus diarrhea in Korean children. Methods : Six...
Differential Excretion of Urinary Eosinophil Protein X after Methacholine Challenge Test in Children with Asthma
Su-A Shin, Jae-Won Oh, Ha-Baik Lee
Clin Exp Pediatr. 2003;46(5):495-499.   Published online May 15, 2003
Purpose : Eosinophil is one of the important inflammatory cell involved in the airway inflammation in childhood asthma. It has been demonstrated that markers of eosinophil activation, including eosinophil cationic protein or eosinophil protein X(EPX), are increased in childhood asthma. Furthermore, they are related to disease activity and are assumed to be helpful in monitoring the treatment effect as urinary...
Effect of Parenteral Nutrition Guideline Changes on Neonatal Sepsis in Premature Infants
Chang-Ryul Kim, Jae-Won Oh, Myung-Kul Yum, Soo-Jee Moon
Clin Exp Pediatr. 2001;44(6):620-626.   Published online June 15, 2001
Purpose : We hypothesized that decreased parenteral nutrition would lower the incidence of neonatal sepsis in premature infants. Methods : The study involves 223 premature infants who were admitted to the neonatal intensive care unit of Hanyang University Kuri Hospital from July 1995 to January 1999. Infants were divided into two groups based on different parenteral nutrition guidelines : Old...
Risk Factors for Neonatal Sepsis in Premature Infants Admitted to Neonatal Intensive Care Unit
Chang-Ryul Kim, Jae-Won Oh, Myung-Kul Yum, Soo-Jee Moon
Clin Exp Pediatr. 2000;43(9):1174-1179.   Published online September 15, 2000
Purpose : The purpose of this study is to find out the risk factors of sepsis except the prematurity itself. Methods : Seventy-seven premature infants less than 37 weeks of gestation, who were admitted to the neonatal intensive care unit of Hanyang University Kuri Hospital between July 1995 and December 1996, were enrolled in this study. All 77 premature infants, 14...
Comparison of Phototherapy Guidelines for Neonatal Jaundice in Healthy Term Newborns
Hyo-Jung Kim, Chang-Ryul Kim, Jae-Won Oh, Myung-Kul Yum, Soo-Jee Moon
Clin Exp Pediatr. 1999;41(5):606-613.   Published online May 15, 1999
Purpose : We hypothesized that phototherapy, if the total serum bilirubin(TSB) is ≥14mg/dl, would decrease not only in frequency and duration, but complications due to phototherapy, such as weight loss, rash, temperature instability, feeding intolerance, and diarrhea, would decrease when compared to phototherapy TSB ≥10mg/dl after 48 hours of life in healthy term newborns without hemolysis. Methods : Forty healthy newborns...
Autonomic Activity, Cardiac Chaos and Circadian Rhythm in Asymptomatic Children with Postoperative Tetralogy of Fallot
Myung-Kul Yum, Nam-Su Kim, Jae-Won Oh, Chang-Ryul Kim, Chul-Burm Lee, June Huh, Chung-Il Noh
Clin Exp Pediatr. 1998;41(11):1517-1529.   Published online November 15, 1998
Purpose : This study aimed to characterize the autonomic and chaotic control of heart rate and circadian rhythm in asymptomatic patients with postoperative tetralogy of Fallot(pTOF). Methods : Twenty-four-hour electrocardiogram recordings were obtained in 30 asymptomatic pTOF patients and in 30 age-and sex-matched controls, aged between 6 and 11 years. The data was digitized and partitioned into sections of 30-...
Developmental Changes of Spectral and Chaotic Indexes of Heart Rate Variability in Normal Fetuses
Jee-Young Jung, Myung-Kul Yum, Nam-Su Ki, Jae-Won Oh, Chang-Ryul Kim, Jung Hye Hwang, Moon-Il Park
Clin Exp Pediatr. 1998;41(10):1380-1388.   Published online October 15, 1998
Purpose : The purposes of this study were to determine the normal values of spectral and chaotic indexes and to assess the maturational process of autonomic and chaotic control of fetal heart rate according to gestational age. Methods : Three hundred and thirty-seven mothers with normal singleton pregnancies, who were 23 weeks or more in gestational age, was randomly chosen. For...
