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.

Niek B. Achten, J. Wendelien Dorigo-Zetsma, Annemarie M.C. van Rossum, Rianne Oostenbrink, Frans B. Plötz
Clin Exp Pediatr. 2020;63(10):406-410.   Published online April 16, 2020
Question: To what extent does risk-based Group B Streptococcus (GBS) screening influence management recommendations by the early-onset sepsis (EOS) calculator?
Finding: In 97% of the newborn infants, the EOS calculator recommendation remained unchanged after the GBS status at birth was updated to the definitive GBS status.
Meaning: Risk-based GBS screening results are compatible with EOS calculator recommendations.

Clin Exp Pediatr. 2015;58(1):33-36.   Published online January 31, 2015

Group D streptococci are known to cause newborn septicemia and meningitis, but the Streptococcus bovis group strains rarely cause serious neonatal infections in Korea. Central nervous system (CNS) complications of neonatal S. bovis group infection have rarely been reported. In adults, S. bovis group strains cause bacteremia and endocarditis, and are associated with gastrointestinal malignancy. However, only a few studies...

Effect of Granulocyte-macrophage Colony-stimulating Factor in Neonatal Infection
Il-Young Jo, Sang-Hyun Byun
Clin Exp Pediatr. 2000;43(12):1552-1557.   Published online December 15, 2000
Purpose : Neutrophils are central to the defences against bacterial infection, and in neonates the number of neutrophils are decreased due to inhibited production and phagocytic function. This induces high mortality rates in infants suffering from neonatal sepsis. Exogenous GM-CSF can increase the number of neutrophils and improve the phagocytic function. To establish the most cost effective dose of exogenous...
