BACKGROUND: Community-acquired pneumonia (CAP) is one of the leading worldwide causes of childhood morbidity and mortality. Its disease burden varies by age and etiology and is time dependent. We aimed to investigate the annual and seasonal patterns in etiologies of pediatric CAP requiring hospitalization. METHODS: We conducted a retrospective study in 30,994 children (aged 0-18 years) with CAP between 2010 and 2015 at 23 nationwide hospitals in South Korea. Mycoplasma pneumoniae (MP) pneumonia

BACKGROUND: The growing prevalence of overweight and/or obese children is an important public health problem in both developed and developing countries. Although the association of obesity between parents and their children is well known, its underlying mechanisms are not well established. PURPOSE: This meta-analysis examined parent-child (PC) relationships in obesity and identified factors such as world region and country income level that may influence this relationship. METHODS: We identified

Mycoplasma pneumoniae is a major causative pathogen of community-acquired pneumonia in children, and the treatment of choice is macrolides. There is an increasing trend in reports of refractory clinical responses despite macrolide treatment due to the emergence of macrolide-resistant M. pneumoniae. Early discrimination of macrolide-refractory M. pneumoniae pneumonia (MrMP) from macrolide-sensitive M. pneumoniae pneumonia (MSMP) is vital; however, testing for macrolide susceptibility at the time

Atopic dermatitis (AD) is a common chronic skin disease with a negative influence on adolescent mental health state. We aimed to identify the influencing factors for mental health in adolescents with AD. We used data from the 13th Korean Youth Risk Behavior Web-based Survey (KYRBS) conducted in 2017. KYRBS data were obtained from a stratified, multistage, clustered sample. Participants responded to the question "have you ever been diagnosed with AD by a doctor?" and several yes/no questions abou

The prevalence of asthma was 2.8% and of depression was 4.1%. Logistic regression analysis showed that single marital status (separated or divorced) (adjusted odds ratio [aOR] 1.291 [95% confidence interval {CI}, 1.077-1.547]), unemployment (aOR 1.226 [95% CI, 1.061-1.417]), under middle school graduated education level (aOR 2.433 [95% CI, 1.867-3.171]), middle school graduated education level (aOR 1.759 [95% CI, 1.330-2.327]), obesity (aOR 1.403 [95% CI, 1.196-1.647]), and depression (aOR 1.796

Based on the assumption that asthma is heterogeneous and each subject exhibits a different subset of risk factors for asthma exacerbation, as well as a different disease progression, the KAS aims to identify several asthma clusters and their essential determinants, which are more suitable for Korean asthmatic children. Thereafter we may suggest cluster-specific strategies by focusing on subjects' personalized aggravating factors during each exacerbation episode and by focusing on disease progres

Purpose: The objective of this study was to investigate the epigenetic role of histone lysine methylation/demethylation on the expression of epithelial-to-mesenchymal transition (EMT) associated transcriptional factors (TFs) during the metastasis of lung adenocarcinoma to the brain. Methods: Paired samples of lung adenocarcinoma and brain metastasis (BM) were analyzed in 46 individual patients. Both samples were obtained by surgical resection or biopsy of the lung and brain. The paraffin-fixed f

This large observational study found that smoking was not associated with hypertension in the overall population, but, when the gender was considered, female smokers were more likely to demonstrate hypertension.

목 적 : 아토피피부염은 피부의 만성 염증질환으로 최근에는 이러한 아토피피부염을 IgE 매개성과 비 IgE 매개성으로 나누고 있으며 양자 간에서는 임상적 증상과 자연경과에서 차이를 보이는 것으로 보고되고 있다. 그러나 이러한 분류에 이용되는 흡입성항원에 대한 피부단자시험이 어려운 경우가 있어 본 저자들은 CAP system을 이용한 혈청검사가 이러한 분류에 유용하게 사용될 수 있는지를 알아보고자 하였다.방 법 : 2002년 6월부터 2005년 2월까지 마산삼성병원 소아과에 내원하였던 5세이상 15세 이하의 아토피피부염 환아 110명을 대상으로 혈청 총 IgE 농도와 집먼지진드기, 난백, 우유, 대두에 대한 특이 IgE농도를 CAP-FEIA을 이용하여 측정하였으며 천식으로 의심되는 경우 환아의 증상과 메타콜린 흡입 후 측정한 기도과민성이 PC20가 8 mg/mL 이하인 경우를 종합하여 천식으로 진단하였고 알레르기비염의 진단은 ARIA guideline을 이용하였다. 결 과 : IgE

= 0.005). Our results suggest that p110α and p110β play different roles depending on tumor stage, and that both p110α and p110β have potential as independent prognostic biomarkers of NSCLC.

Objectives: To assess the relationship between coronary artery changes and periungual desquamation in Kawasaki disease (KD) and non - KD patients. Methods: This retrospective descriptive study was conducted through a review of records of children with KD from March 2011 to February 2016. We also analyzed non - KD subjects with desquamation. Results: Among 329 patients with KD, 177 (53.8%) had periungual desquamation. Subjects with desquamation had longer duration of fever (6.75 ± 2.43 vs. 5.63
