Ji Eun Jeong, Ji Eun Soh, Ji Hee Kwak, Hye Lim Jung, Jae Won Shim, Deok Soo Kim, Moon Soo Park, Jung Yeon Shim
Clin Exp Pediatr. 2018;61(8):258-263.   Published online August 15, 2018

Purpose: Macrolide-resistant Mycoplasma pneumoniae pneumonia (MPP) is characterized by prolonged fever and radiological progression despite macrolide treatment. Few studies have examined serum procalcitonin (PCT) level in children with MPP. We aimed to investigate the association of acute inflammation markers including PCT with clinical parameters in children with MPP. Methods: A total of 147 children were recruited. The diagnosis of MPP...

Pil-Joo Hwang, Ji Hee Kwak, Taek Jin Lee, Su Jin Jeong
Clin Exp Pediatr. 2009;52(4):453-457.   Published online April 15, 2009
Purpose : Our aim was to describe the clinical features of noroviral gastroenteritis in children. Methods : This study included 22 children with noroviral gastroenteritis, as confirmed by stool RT-PCR, who were admitted to Bundang CHA Hospital between July 2006 and June 2008. Their medical records were reviewed and compared with those of 45 children with rotaviral gastroenteritis. Results : In the...

This study aimed to evaluate the safety and efficacy of ultra-rush therapy using Dermatophagoides extracts in children. Methods : Of children older than four years who had visited Bundang CHA Pediatric Allergy Clinic, those showing positive...
A comparison between impulse oscillometry system and spirometry for spirometry for detecting airway obstruction in children
Hae Young Hur, Ji Hee Kwak, Hyoung Yun Kim, Da Wun Jung, Yoon Ho Shin, Man Yong Han
Clin Exp Pediatr. 2008;51(8):842-847.   Published online August 15, 2008
Purpose : Measurement of forced expiratory volume in 1 second (FEV1) is usually difficult to obtain in children under six years of age because it requires active cooperation. This study evaluates the sensitivity of impulse oscillometry system (IOS) parameters for detecting airway obstruction in comparison with FEV1. Methods : We studied 174 children who performed the lung function and methacholine challenge...
