Impacts of maternal COVID-19 during pregnancy on neonatal health and epidemiology
Jae Woo Lim
Clin Exp Pediatr. 2024;67(3):149-151.   Published online December 28, 2023
Newborns born to mothers infected with coronavirus disease 2019 (COVID-19) should be closely monitored for respiratory disorders, such as transient tachypnea of the newborn, regardless of their COVID-19 test results. Further research is required of the development of infants born to mothers with COVID-19. The trends in Korea's birth rate and infant mortality rates have not been significantly affected by COVID-19.

The improvement of right ventricular function after adenotonsillectomy in children with obstructive sleep apnea
Dong Yeop Kim, Kyung Ok Ko, Jae Woo Lim, Jung Min Yoon, Young Hwa Song, Eun Jeong Cheon
Clin Exp Pediatr. 2018;61(12):392-396.   Published online October 26, 2018

Purpose: Adenotonsillar hypertrophy (ATH) that causes upper airway obstruction might lead to chronic hypoxemic pulmonary vasoconstriction and right ventricular (RV) dysfunction. We aimed to evaluate whether adenotonsillectomy (T&A) in children suffering from obstructive sleep apnea (OSA) due to severe ATH could improve RV function. Methods: Thirty-seven children (boy:girl=21:16; mean age, 9.52±2.20 years), who underwent T&A forsleep apnea due to ATH, were...

Granular cell tumor of the esophagus in an adolescent
Ji Sun Lee, Kyung Ok Ko, Jae Woo Lim, Eun Jeong Cheon, Young Jin Kim, Jang Sin Son, Jung Min Yoon
Clin Exp Pediatr. 2016;59(Suppl 1):S88-S91.   Published online November 30, 2016

Esophageal granular cell tumor (GCT) is a rare neoplasm originating from the Schwann cells of the submucosal neuronal plexus. Histology is the gold standard for its diagnosis. Endoscopic resection or surgical excision should be considered, depending on the potential for malignancy. Here, we report a case of an esophageal GCT in an adolescent. A 12-year-old boy presented with a 1-year...

Interstitial deletion of 5q33.3q35.1 in a boy with severe mental retardation
Jin Hwan Lee, Hyo Jeong Kim, Jung Min Yoon, Eun Jung Cheon, Jae Woo Lim, Kyong Og Ko, Gyung Min Lee
Clin Exp Pediatr. 2016;59(Suppl 1):S19-S24.   Published online November 30, 2016

Constitutional interstitial deletions of the long arm of chromosome 5 (5q) are quite rare, and the corresponding phenotype is not yet clearly delineated. Severe mental retardation has been described in most patients who present 5q deletions. Specifically, the interstitial deletion of chromosome 5q33.3q35.1, an extremely rare chromosomal aberration, is characterized by mental retardation, developmental delay, and facial dysmorphism. Although the...

Age-adjusted plasma N-terminal pro-brain natriuretic peptide level in Kawasaki disease
Heul Jun, Kyung Ok Ko, Jae Woo Lim, Jung Min Yoon, Gyung Min Lee, Eun Jung Cheon
Clin Exp Pediatr. 2016;59(7):298-302.   Published online July 31, 2016
Purpose

Recent reports showed that plasma N-terminal pro-brain natriuretic peptide (NT-proBNP) could be a useful biomarker of intravenous immunoglobulin (IVIG) unresponsiveness and coronary artery lesion (CAL) development in Kawasaki disease (KD). The levels of these peptides are critically influenced by age; hence, the normal range and upper limits for infants and children are different. We performed an age-adjusted analysis of plasma...

Case Report
A pediatric case of Bickerstaff's brainstem encephalitis
Ju Yi Park, Kyong Og Ko, Jae Woo Lim, Eun Jung Cheon, Jung Min Yoon, Hyo Jeong Kim
Clin Exp Pediatr. 2014;57(12):542-545.   Published online December 31, 2014

Bickerstaff's brainstem encephalitis is characterized by ophthalmoplegia, ataxia, and disturbance of consciousness. It is similar to Miller Fisher syndrome, a variant of Guillain-Barre syndrome, in that they share features such as ophthalmoplegia and ataxia. The difference is that patients with Bickerstaff's brainstem encephalitis have impaired consciousness, whereas patients with Miller Fisher syndrome have alert consciousness and areflexia. Here, we report...

Jin Hwan Lee, Jung Min Yoon, Jae Woo Lim, Kyung Og Ko, Seong Jun Choi, Jong-Yeup Kim, Eun Jung Cheon
Clin Exp Pediatr. 2014;57(11):484-488.   Published online November 30, 2014
Purpose

Chronic upper airway obstruction causes hypoxemic pulmonary vasoconstriction, which may lead to right ventricle (RV) dysfunction. Adenotonsillar hypertrophy (ATH) is the most common cause of upper airway obstruction in children. Therefore, we aimed to evaluate RV function in children with ATH.

Methods

Twenty-one children (male/female, 15/6; mean age, 92.3¡¾39.0 months; age range, 4-15 years) with ATH and 21 healthy age- and gender-matched...

Clin Exp Pediatr. 2011;54(11):429-435.   Published online November 30, 2011

Although Korean population has been growing steadily during the past four decades, the nation is rapidly becoming an aging society because of its declining birth rate combined with an increasing life expectancy. In addition, Korea has one of the lowest fertility rates in the world due to fewer married couples, advanced maternal age, and falling birth rate. The prevalence of...

Clin Exp Pediatr. 2008;51(5):542-545.   Published online May 15, 2008
Epidural hematoma (EDH) is relatively rare in newborn infants and frequently associated with instrumental deliveries or other complications during labor and delivery. Although surgical evacuation has been the most common therapy, many other procedures have been suggested. Although many epidural hematomas require surgical evacuation rather than non-surgical management, the conservatiob or aspiration of hematoma have been attempted. In the case...
