Importance of pulmonary valve morphology for pulmonary valve preservation in tetralogy of Fallot surgery: comparison of the echocardiographic parameters

Clin Exp Pediatr. 2020;63(5):189-194.   Published online November 8, 2019
Question: Is echocardiographic examination is useful for surgical method decision in patients with tetralogy of Fallot (TOF)?
Finding: Various echocardiographic parameters serve as predictors for determining surgical methods for TOF patients. However, the PV morphology and tissue characteristics should also be considered.
Meaning: A full dependence on the size of the pulmonary valve annulus (PVA), the z score, and the ratio of the size of PVA to aortic valve annulus or descending aorta surgery may result in inadequate surgical results during TOF total correction.

Comparison of cytokine expression profiles in infants with a rhinovirus induced lower respiratory tract infection with or without wheezing: a comparison with respiratory syncytial virus
Da Eun Roh, Sook-Hyun Park, Hee Joung Choi, Yeo Hyang Kim
Clin Exp Pediatr. 2017;60(9):296-301.   Published online September 21, 2017
Purpose

The aim of this study was to evaluate whether infants with rhinovirus (RV) infection-induced wheezing and those with respiratory syncytial virus (RSV) infection-induced wheezing have different cytokine profiles in the acute stage.

Methods

Of the infants with lower respiratory tract infection (LRTI) between September 2011 and May 2012, 88 were confirmed using reverse transcription polymerase chain reaction and hospitalized. Systemic interferon-gamma (IFN-γ),...
