Clin Exp Pediatr. 2015;58(9):330-335.   Published online September 21, 2015
Purpose

The clinical interpretation of children sensitized to allergens is challenging, particularly in children with food allergies. We aimed to examine clinical differences between children with monosensitization and those with polysensitization to common food allergens and to determine risk factors for polysensitization in young children <10 years of age with immediate-type food allergies.

Methods

The study included children <10 years of age with...

Increased B cell-activating factor (BAFF) level in the sputum of children with asthma
Hye Mi Jee, Bong Seok Choi, Kyung Won Kim, Myung Hyun Sohn, Man Yong Han, Kyu-Earn Kim
Clin Exp Pediatr. 2010;53(8):795-800.   Published online August 31, 2010
Purpose

B cell-activating factor (BAFF) is a tumor-necrosis factor (TNF) superfamily member best known for its role in the survival and maturation of B cells. BAFF activity is observed in naïve cells as well as in effector/memory T cells. We aimed to explore whether BAFF in sputum is expressed at elevated levels in asthmatic airways and associated with eosinophilic inflammation, pulmonary...

Thymolipoma in a 13-year-old Korean girl
Su-Jin Park, Ji Young Baek, Junjeong Choi, Kyung Won Kim, Myung Joon Kim, Myung Hyun Sohn, Kyu-Earn Kim
Clin Exp Pediatr. 2010;53(1):103-105.   Published online January 15, 2010
Thymolipoma is a rare benign tumor of anterior mediastinum. Most patients are asymptomatic with incidental finding of the tumor during a diagnostic workup of other medical problems. We present a case of 13-year-old girl with anterior mediastinal thymolipoma, surgically removed after an incidental diagnosis.

Toll-like receptor 9 expression and interferon-α secretion upon CpG-ODN stimulation in allergic subjects
Man Yong Han, Hye Mi Jee, Hyeong Yoon Kim, Cho Ae Lee, Hyo-Jin Cho, Seong-Gyu Hwang, Kyu-Earn Kim
Clin Exp Pediatr. 2009;52(9):1015-1020.   Published online September 15, 2009

Purpose:The aim of this study is to explore the effect of the Toll-like receptor 9 (TLR9) expressed in plasmacytoid dendritic cells (pDCs) that respond to antigen to Th2 immune deviation in allergic patients. Methods:Subjects consisted of 19 allergic patients and 17 healthy volunteers. Skin prick tests and nasal provocation tests were performed for the two groups. Peripheral blood mononuclear cells (PBMCs)...

Clin Exp Pediatr. 2009;52(3):324-329.   Published online March 15, 2009
Purpose : Acute interstitial pneumonia (AIP) is a rare disease, but its prognosis is fatal because of lack of efficient treatment modality. Recently, it has been reported that there was epidemic AIP in Korea. This study aims to investigate the past and current status of AIP in Korea. Methods : We performed a nationwide survey and a prospective study. From August...

Mycoplasma and chlamydia infection in Korea
Kyung Won Kim, Kyu-Earn Kim
Clin Exp Pediatr. 2009;52(3):277-282.   Published online March 15, 2009
Pneumonia, which usually requires hospitalization for children, is caused by various pathogens. According to recent surveys, the prevalence of atypical pneumonia caused by Mycoplasma or Chlamydia has increased, especially in preschool children. Also, the evidence has been accumulated that Mycoplasma or Chlamydia infection is associated with asthma including both inception and exacerbation. Therefore, it is important to consider how the...
The prevalences of asthma and allergic diseases in Korean children
Soo-Jong Hong, Kang-Mo Ahn, Soo-Young Lee, Kyu-Earn Kim
Clin Exp Pediatr. 2008;51(4):343-350.   Published online April 15, 2008
Asthma and allergic diseases are one of the most common disorders in children. Due to its increased prevalence, as well as the increased morbidity and mortality from these diseases, asthma and allergic diseases have come to be recognized as a major worldwide public health issue. In addition, socioeconomic burden of asthma and allergic diseases has increased in Korea also. The...

Utility of a forced expiratory flow of 25 to 75 percent as a predictor in children with asthma
Jung Wan Kang, Kyung Won Kim, Eun Soo Kim, Jun Young Park, Myung Hyun Sohn, Kyu-Earn Kim
Clin Exp Pediatr. 2008;51(3):323-328.   Published online March 15, 2008
Purpose : Asthma is defined as chronic inflammation of the lower small airways, and bronchial hyperreactivity (BHR) is a pathophysiologic feature of asthma. It has been proposed that although there is no direct variable capable of assessing the small airways, a forced expiratory flow of between 25 and 75 percent (FEF25-75) might be considered a more sensitive early marker of...
Mycoplasma pneumoniae-induced production of proasthmatic mediators in airway epithelium
Kyung Won Kim, Byung Chul Lee, Kyung Eun Lee, Eun Soo Kim, Tae Won Song, Mi Yeoun Park, Myung Hyun Sohn, Kyu-Earn Kim
Clin Exp Pediatr. 2006;49(9):977-982.   Published online September 15, 2006
Purpose : There has been an increasing amount of literature concerning the association between Mycoplasma pneumoniae and asthma pathogenesis. Interleukin(IL)-6 stimulates the differentiation of monocytes, and can promote Th2 differentiation and simultaneously inhibit Th1 polarization. IL-8 is a potent chemoattractant and, it has been suggested, has a role in asthma pathogenesis. Nitric oxide (NO) synthesized by airway epithelium may be...
Effects of Hyperosmolar Stimuli on Activation of Human Eosinophilic Leukaemia EoL-1 Cells

Clin Exp Pediatr. 2005;48(8):881-885.   Published online August 15, 2005
Purpose : Airway dehydration and subsequent hyperosmolarity of periciliary fluid are considered critical events in exercise-induced bronchoconstriction. The aim of this study was to establish if a hyperosmolar challenge could induce activation of eosinophils. Methods : Human eosinophilic leukaemic cell lines, EoL-1 cells were incubated with hyperosmolar solutions for 15 minutes. Activation of EoL-1 cells was monitored by degranulation and superoxide...
