Etiological and pathophysiological enigmas of severe coronavirus disease 2019, multisystem inflammatory syndrome in children, and Kawasaki disease
Jung-Woo Rhim, Jin-Han Kang, Kyung-Yil Lee
Clin Exp Pediatr. 2022;65(4):153-166.   Published online November 23, 2021
· Severe cases of coronavirus disease, Kawasaki disease (KD), and multisystem inflammatory syndrome in children (MIS-C) share similar findings: a protracted clinical course, multiorgan involvement, and similar activated biomarkers.
· Here we propose etiological agents in KD and MIS-C as species in the microbiota and introduce a common pathogenesis through the protein-homeostasis-system hypothesis.
· Early proper dose of corticosteroids and/or intravenous immunoglobulin may help to reduce morbidity and mortality in these diseases.

Clin Exp Pediatr. 2020;63(7):239-250.   Published online June 18, 2020
The novel coronavirus disease 2019 (COVID-19) is spreading globally. Although its etiologic agent is discovered as severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), there are many unsolved issues in COVID-19 and other infectious diseases. The causes of different clinical phenotypes and incubation periods among individuals, species specificity, and cytokine storm with lymphopenia as well as the mechanism of damage to organ...

Jin-Han Kang
Clin Exp Pediatr. 2014;57(4):164-170.   Published online April 30, 2014

Influenza causes acute respiratory infections and various complications. Children in the high-risk group have higher complication and hospitalization rates than high-risk elderly individuals. Influenza prevention in children is important, as they can be a source infection spread in their communities. Influenza vaccination is strongly recommended for high-risk children with chronic underlying circulatory and respiratory disease, immature infants, and children receiving...

Clin Exp Pediatr. 2003;46(5):467-473.   Published online May 15, 2003
Purpose : The Epstein-Barr virus(EBV), gamma herpesvirus, is an important pathogen that is widespread around the world. The EBV causes various diseases depending on the geographic location, and on the immunity or the premorbid condition of the person exposed to EBV. To evaluate EBV typing may be the most important step to figure out the pathogenesis of EBV associated diseases,...

Purpose : Klebsiella pneumoniae is a major nosocomial pathogen in neonatal intensive care unit (NICU). Sequential outbreaks of K. pneumoniae infection in NICU could occur due to antibiotic resistant strains or persistent environmental sources in NICU. When these outbreaks are happen, epidemiological analysis must be performed to discover the nosocomial sources and clarify the nature of the outbreaks strains. We...
A Clinical Study of Atypical Kawasaki Disease - A Rate of Coronary Artery Involvement -
