Ju Young Kim, Moon Souk Lee, Seung Yeon Kim, Hyun Jung Kim, Soo Jin Lee, Chur Woo You, Jon Soo Kim, Ju Hyung Kang
Clin Exp Pediatr. 2016;59(Suppl 1):S125-S128.   Published online November 30, 2016

Harlequin syndrome, which is a rare disorder caused by dysfunction of the autonomic system, manifests as asymmetric facial flushing and sweating in response to heat, exercise, or emotional factors. The syndrome may be primary (idiopathic) with a benign course, or can occur secondary to structural abnormalities or iatrogenic factors. The precise mechanism underlying idiopathic harlequin syndrome remains unclear. Here, we...

Clinical outcome of patients with refractory Kawasaki disease based on treatment modalities
Hyun Jung Kim, Hyo Eun Lee, Jae Won Yu, Hong Ryang Kil
Clin Exp Pediatr. 2016;59(8):328-334.   Published online August 24, 2016
Purpose

Although a significant number of reports on new therapeutic options for refractory Kawasaki disease (KD) such as steroid, infliximab, or repeated intravenous immunoglobulin (IVIG) are available, their effectiveness in reducing the prevalence of coronary artery lesions (CAL) remains controversial. This study aimed to define the clinical characteristics of patients with refractory KD and to assess the effects of adjuvant therapy...

Correlation between the morning hypertension on ambulatory blood pressure monitoring and the left ventricular mass in children
Hyun Jung Kim, Kyung Hee Kim, Hong Ryang Kil
Clin Exp Pediatr. 2014;57(9):403-409.   Published online September 30, 2014
Purpose

Although high morning blood pressure (BP) is known to be associated with the onset of cardiovascular events in adults, data on its effects in children with hypertension are limited. Our retrospective study aimed to define the clinical characteristics of children with morning hypertension (MH) and to determine its associated factors.

Methods

We reviewed 31 consecutive patients with hypertension, confirmed by the ambulatory...

Case Report
A case of Kawasaki disease with coexistence of a parapharyngeal abscess requiring incision and drainage
Se Hyun Choi, Hyun Jung Kim
Clin Exp Pediatr. 2010;53(9):855-858.   Published online September 13, 2010

Kawasaki disease (KD) causes multisystemic vasculitis but infrequently manifests with deep neck infections, such as a peritonsillar abscess, peritonsillar or deep neck cellulitis, suppurative parapharyngeal infection, or retropharyngeal abscess. As its etiology is still unknown, the diagnosis is usually made based on typical symptoms. The differential diagnosis between KD and deep neck infections is important, considering the variable head and...

Clinical outcome of acute myocarditis in children according to treatment modalities
Hyun Jung Kim, Gyeong-Hee Yoo, Hong Ryang Kil
Clin Exp Pediatr. 2010;53(7):745-752.   Published online July 31, 2010
Purpose

There is currently little evidence to support intravenous immune globulin (IVIG) therapy for pediatric myocarditis. The purpose of our retrospective study was to assess the effects of IVIG therapy in patients with presumed myocarditis on survival and recovery of ventricular function and to determine the factors associated with its poor outcome.

Methods

We reviewed all consecutive cases of patients with myocarditis with...

Case Report
Two cases of Kawasaki disease following pneumonia
Hyun Jung Kim, Soo Jin Lee
Clin Exp Pediatr. 2009;52(5):615-618.   Published online May 15, 2009
Kawasaki disease (KD) causes multisystemic vasculitis but rarely manifests with pulmonary symptoms. As its etiology is still unknown, there are no specific diagnostic tools available, and KD can be diagnosed only by the symptom pattern. The presence of unusual clinical manifestations often leads to delayed diagnosis. Here, we report two cases of KD with an initial presentation of pneumonia. KD...

Clinical factors causing hyponatremia in patients with mucocutaneous lymph node syndrome
Soo Yeon Kim, Hyun Jung Kim, Jun Seok Choi, Jae Kyung Huh
Clin Exp Pediatr. 2009;52(3):364-369.   Published online March 15, 2009
Purpose : Clinical and laboratory findings predict a severe outcome for mucocutaneous lymph node syndrome. This study aimed to define the clinical characteristics of Kawasaki disease (KD) patients with hyponatremia and to determine the factors associated with its development. Methods : Retrospective studies were performed on 114 KD patients who received an initial high-dose intravenous immunoglobulin (IVIG, single 2 g/kg/dose)...
Analysis of disease mechanism of subacute necrotizing lymphadenitis in children
Hyun Jung Kim, Jung Suk Yeom, Ji Suk Park, Eun Sil Park, Ji Hyun Seo, Jae Young Lim, Chan Hoo Park, Hyang Ok Woo, Jae Min Cho, Jeong Hee Lee, Hee Shang Youn
Clin Exp Pediatr. 2008;51(11):1198-1204.   Published online November 15, 2008
Purpose : The cause of subacute necrotizing lymphadenitis, a rare disease in children, has not been completely clarified. This study was aimed to investigate the disease mechanism by examining clinical, radiologic, and immunohistochemical findings in children diagnosed with subacute necrotizing lymphadenitis after an excisional biopsy. Methods : We examined 19 lymph node tissue specimens from 17 children diagnosed with subacute...

Clin Exp Pediatr. 2003;46(6):597-601.   Published online June 15, 2003
Trisomy 9 mosaic syndrome is a rarely reported chromosomal abnormality with high incidence of intrauterine growth retardation and perinatal death. Even a baby lives, he has severe mental retardation and significant malformations. The incidence and severity of malformations and mental retardation correlate with the percentage of trisomic cells in the different tissues. The characteristic craniofacial abnormalitis are narrow bifrontal diameter,...
