Implication of microRNA as a potential biomarker of myocarditis
Jin-Hee Oh, Gi Beom Kim, Heeyoung Seok
Clin Exp Pediatr. 2022;65(5):230-238.   Published online March 2, 2022
· Myocarditis was recently examined quantitatively as inflammation of the heart muscle based on endomyocardial biopsy, and its noninvasive diagnosis remains unsatisfactory.
· Additionally, numerous miRNAs (miR-155, miR-146b, miR-590, miR-221, miR-222, etc.) coupled with inflammation or viral activation have been examined in myocarditis patients or mouse models.
· The recent identification of mmu-miR-721 (has-miR-Chr8: 96), a myocarditis-specific microRNA, demonstrated its potential as an acute myocarditis biomarker.

The use of extracorporeal membrane oxygenation in children with acute fulminant myocarditis
Silver Heinsar, Sainath Raman, Jacky Y. Suen, Hwa Jin Cho, John F. Fraser
Clin Exp Pediatr. 2021;64(5):188-195.   Published online August 10, 2020
Acute fulminant myocarditis (AFM) occurs as an inflammatory response to an initial myocardial insult. Its rapid and deadly progression calls for prompt diagnosis with aggressive treatment measures. The demonstration of its excellent recovery potential has led to increasing use of mechanical circulatory support, especially extracorporeal membrane oxygenation (ECMO). Arrhythmias, organ failure, elevated cardiac biomarkers, and decreased ventricular function at presentation...

Successfully treated infective endocarditis caused by methicillin-resistant Staphylococcus Aureus in extremely low birth weight infant
Sehwa Jung, Kyung Uk Jeong, Jang Hoon Lee, Jo Won Jung, Moon Sung Park
Clin Exp Pediatr. 2016;59(2):96-99.   Published online February 29, 2016

Survival rates of preterm infants have improved in the past few decades, and central venous catheters play an important role in the intensive medical treatment of these neonates. Unfortunately, these indwelling catheters increase the risk of intracardiac thrombosis, and they provide a nidus for microorganisms during the course of septicemia. Herein, we report a case of persistent bacteremia due to...

The first pediatric case of tularemia in Korea: manifested with pneumonia and possible infective endocarditis
Jung Sook Yeom, Kyuyol Rhie, Ji Sook Park, Ji-Hyun Seo, Eun Sil Park, Jae-Young Lim, Chan-Hoo Park, Hyang-Ok Woo, Hee-Shang Youn
Clin Exp Pediatr. 2015;58(10):398-401.   Published online October 21, 2015

Tularemia is a potentially severe zoonotic disease caused by Francisella tularensis. A lack of awareness about tularemia can be embarrassing and could result in delayed treatment because of improper diagnosis. The diagnosis of tularemia is difficult, because the infections are rare and the clinical spectrum is broad. As only 1 adult case has been reported in Korea thus far, pediatricians...

Sunhee Bang, Jeong Jin Yu, Myung-Ki Han, Hong Ki Ko, Sail Chun, Hyung Soon Choi, Young-Hwue Kim, Jae-Kon Ko, In-Sook Park
Clin Exp Pediatr. 2011;54(8):340-344.   Published online August 31, 2011
Purpose

Brain natriuretic peptide (BNP) has been considered a biochemical marker for myocarditis in Kawasaki disease. We performed this study to determine its quantitative significance.

Methods

We attempted to correlate log-transformed BNP concentrations (log-BNP) and clinical, laboratory, and echocardiographic variables in 81 children with Kawasaki disease. Stepwise multiple linear regression analysis was used to determine the variables independently associated with log-BNP concentration.

Hong Ryang Kil
Clin Exp Pediatr. 2007;50(11):1049-1054.   Published online November 15, 2007
Myocarditis represent an important condition encountered by general pediatricians & general practitioners. Its presentation is varied, and therefore a high index of suspicion must be maintained when the possibility of myocarditis is raised. A progression from viral myocarditis to dilated cardiomyopathy has long been hypothesized. Treatment is initially aimed at achieving hemodynamic stability and is largely supportive. There is currently...

Constrictive pericarditis represents a rare cause of protein-losing enteropathy in children. Reported is an 11-year-old girl with protein-losing enteropathy (PLE) as the principal manifestations of constrictive pericarditis. After total pericardiectomy, symptoms and signs of PLE disappeared. Doppler echocardiography including tissue Doppler imaging is a useful noninvasive initial diagnostic tool for differential diagnosis of diastolic heart failure.
