· 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. |

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... |
We retrospectively analyzed 779 medical records of children (0-15 years of old) with MP pneumonia admitted to our institution and compared the data from 3 recent epidemics. In 779 patients, the mean age... |
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... |
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 : AOM is the most common bacterial URI in children. The bacteriology and antibiotic Tx of AOM in children has been studied in many countries. But, there is few study of causative pathogens and antibiotic Tx of AOM in our country. In this aspect, we performed prospective clinical study to confirm the causative pathogens and assess the clinical responses... |
Purpose : We evaluated clinical manifestations and laboratory findings in patients with measles according to age distribution. Methods : Retrospective analyses were performed using medical records of patients with measles admitted to The Catholic University of Korea, Daejon St. Mary's Hospital from October 2000 to May 2001. We divided the patients with measles into three age groups, i.e., those who were... |
Purpose : Recurrent parotitis is defined as a recurrent parotid inflammation, generally associated with sialectasis of the parotid gland. It can often be misdiagnosed as recurrent mumps. We studied the clinical and laboratory features of recurrent parotitis. Methods : Outpatient clinical records of 23 cases were analyzed retrospectively between April 1993 and March 1999. Follow-up after the last outpatient clinic... |
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... |
Purpose : Without a specific diagnostic method, the clinical diagnostic criteria for atypical Kawasaki disease is known as the presence of coronary artery changes in a patient who did not meet the already estabilished clinical criteria. With this criteria, we are put into dilemma because atypical Kawasaki disease should exhibit coronary artery disease. So, we demonstrated the rate of coronary artery involvement in atypical... |
Purpose : The aim of this study was to elucidate the pathogenesis of vertical transmission of hepatitis B virus(HBV), and to study the protective efficacy of the vaccine and hepatitis B immune globulin(HBIG). Methods : Eighty-two infants born from HBV carrier mothers were studied. HBV plasma-derived vaccine and HBIG were administered to their neonates. Then, changes of viral markers, anti-preS2... |
Purpose : We experienced an outbreak of hepatitis A in Taejon, Korea for the summer of 1996. Recently a shift in hepatitis A incidence from children to adults has been well noted in Korea. For the purpose of possible measures in preventing hepatitis A, we studied a seroepidemiology of hepatitis A in Taejon. Methods : We measured IgG anti-HAV antibody(HAVAB MEIA, Abbott) from 722... |
