Prevalence, comorbidities, diagnosis, and treatment of nonallergic rhinitis: real-world comparison with allergic rhinitis
Hye Yung Yum, Eun Kyo Ha, Yoon Ho Shin, Man Yong Han
Clin Exp Pediatr. 2021;64(8):373-383.   Published online August 10, 2020
Rhinitis is among the most common respiratory diseases in children. Nonallergic rhinitis, which involves nasal symptoms without evidence of systemic allergic inflammation or infection, is a heterogeneous entity with diverse manifestations and intensities. Nonallergic rhinitis accounts for 16%–89% of the chronic rhinitis cases, affecting 1%–50% (median 10%) of the total pediatric population. The clinical course of nonallergic rhinitis is generally...

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...
Reference values for respiratory system impedance using impulse oscillometry in school-aged children in Korea
Young Sun Wee, Hyoung Yun Kim, Da Wun Jung, Hye Won Park, Yoon Ho Shin, Man Yong Han
Clin Exp Pediatr. 2007;50(9):862-867.   Published online September 15, 2007
Purpose : The impulse oscillometry (IOS) is applicable to young children because it requires minimal cooperation and a non-invasive method to measure the mechanics of respiratory system. This study aimed to develop the reference values in school-aged children in Korea, using IOS which is a modification of forced oscillation technique (FOT). Methods : Measurements were performed in 92 previously untrained healthy...
