Clin Exp Pediatr. 2022;65(7):350-357.   Published online December 9, 2021
Question: What is prevalence of bacterial pathogens causing sepsis and their antimicrobial susceptibility over 20 years?
Finding: Coagulase-negative remains most common causative organism. The most common gram-negative organism was Klebsiella pneumonia. The susceptibility of staphylococcus aureus and K. pneumonia showed increased susceptability to oxacillin, cefotaxime and amikacin, gentamicin, respectively.
Meaning: Answers to the question asked is important in choosing antimicrobials and to monitor emergence of multidrug-resistant organisms.

Validity of the Korean Developmental Screening Test for very-low-birth-weight infants
Chae Young Kim, Euiseok Jung, Byong Sop Lee, Ki-Soo Kim, Ellen Ai-Rhan Kim
Clin Exp Pediatr. 2019;62(5):187-192.   Published online March 20, 2019

Purpose: The importance of the neurodevelopmental outcomes of very-low-birth-weight (VLBW) infants has been emphasized as their mortality rate has markedly improved. This study aimed to assess the validity of the Korean Developmental Screening Test (K-DST), a developmental screening tool approved by the Korean Society of Pediatrics, for the timely diagnosis of neurodevelopmental delay in VLBW infants. Methods: Subjects included VLBW infants...

Case of mucinous adenocarcinoma of the lung associated with congenital pulmonary airway malformation in a neonate
Juneyoug Koh, Euiseok Jung, Se Jin Jang, Dong Kwan Kim, Byong Sop Lee, Ki-Soo Kim, Ellen Ai-Rhan Kim
Clin Exp Pediatr. 2018;61(1):30-34.   Published online January 22, 2018

Congenital pulmonary airway malformation (CPAM), previously known as congenital cystic adenomatoid malformation, is a rare developmental lung abnormality associated with rhabdomyosarcoma, pleuropulmonary blastoma, and mucinous adenocarcinoma of the lung. We report an unusual case of a 10-day-old male newborn with a left lower lobe pulmonary cyst who underwent lobectomy, which revealed type II CPAM complicated by multifocal mucinous adenocarcinoma. KRAS...

Nutritional strategy of early amino acid administration in very low birth weight infants
Byong Sop Lee
Clin Exp Pediatr. 2015;58(3):77-83.   Published online March 20, 2015

Relative to a fetus of the same gestational age, very low birth weight (VLBW) infants are more likely to be underfed and to undergo growth restriction during their early hospital stay. The current trend towards "early and aggressive" nutritional strategies in VLBW infants aims to overcome the early nutritional deficiency and thereby boost postnatal catch-up growth, simultaneously improving long-term neurodevelopmental...

Evaluation of immunogenicity of the 2008-2009 seasonal influenza vaccines by microneutralization test
Seung Youn Kim, Yun Kyung Kim, Byung Wook Eun, Nam Hee Kim, Eun Kyeong Kang, Byong Sop Lee, Jung Sub Lim, Jun Ah Lee, Dong Ho Kim
Clin Exp Pediatr. 2012;55(12):474-480.   Published online December 20, 2012
Purpose

For evaluating the immunogenicity of an influenza vaccine, the microneutralization (MN) test has a higher sensitivity and specificity as compared to the hemagglutination inhibition (HI) test. However, the MN test is more time consuming and is difficult to standardize. We performed the MN test to determine its usefulness as an alternative or complementary test to the HI test for evaluating...

Therapeutic Efficacy of Cefotaxime as an Empirical Antibiotic on Ascending Cholangitis after Kasai Operation for Biliary Atresia
Dong Ho Kim, Byong Sop Lee, Yun Kyung Kim, Jae Sung Ko, Hoan Jong Lee, Jeong Kee Seo
Clin Exp Pediatr. 2002;45(4):474-481.   Published online April 15, 2002
Purpose : Ascending cholangitis is the most common complication after Kasai operations. The aim of this study is to evaluate the therapeutic efficacy of cefotaxime as an empirical antibiotic on ascending cholangitis after Kasai operations. Methods : Thirty-nine episodes of cholangitis in twenty-nine children who underwent Kasai operations at Seoul National University Children's Hospital from January 1991 to December 2000 were...
