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

We aimed to investigate associations of dietary diversity (DD) with gut microbial diversity and the development of hen's egg allergy (HEA) in infants. We enrolled 68 infants in a high-risk group and 32 infants in a control group based on a family history of allergic diseases. All infants were followed from birth until 12 months of age. We collected infant feeding data, and DD was defined using 3 measures: the World Health Organization definition of minimum DD, food group diversity, and food alle

Oral immunotherapy (OIT) has emerged to build sustained unresponsiveness or tolerance in patients with egg allergy. However, it is important to increase compliance and ensure safety because OIT requires an extended period of time and has a risk of side effects like anaphylaxis. We aimed to show the feasibility and safety of OIT during the build-up phase using a home-based, up-dosing method in children with egg allergy. Sixteen patients aged 4 to 12 years with egg allergy were enrolled. Patients

Background: The association between prenatal exposure to phthalate and childhood atopic dermatitis (AD) has previously been investigated; however, the results are inconsistent. Objective: We aimed to perform a systematic review and meta-analysis of birth cohort studies to investigate whether prenatal exposure to phthalate increases the risk of developing AD in children. Methods: We performed an electronic search of medical literature data bases. Studies were critically appraised, and a meta-anal

Although the prevalence of asthma was similar every year, the prevalence of depression and suicidality among adolescents with asthma decreased. Nevertheless, clinical physicians should pay more attention to screen for depression and suicidality among adolescents with asthma, especially having associated factors.

BACKGROUND: Influenza viral infection is a major public health problem with significant morbidity and mortality.Asthma is a risk factor for developing serious complications related to influenza infection. OBJECTIVE: We explored factors associated with influenza vaccination coverage among adolescents with asthma. METHODS: Data were obtained from 62,276 participants in the 13th Korean Youth Risk Behavior Web-Based Survey (KYRBS) conducted in 2017. KYRBS data were obtained from a stratified, multis

BACKGROUND: Predicting food allergy resolution is essential to minimize the number of restricted foods in children. However, there have been no studies on the natural history of peanut allergy (PA) in Korea. OBJECTIVE: This study aimed to evaluate the natural course and prognostic factors of immediate-type PA in children till the age of 10 years. METHODS: We retrospectively collected data of 122 children who developed PA before 60 months of age from 3 tertiary hospitals in Korea. Diagnosis and r

Postpartum maternal anxiety, mediated by reduced DD and gut microbial diversity, may be a risk factor for the development of FA in infants during the first 2 years of life.

Brugada syndrome is a rare channelopathy associated with the SCN5A gene that causes fatal ventricular arrhythmias. This case of Brugada syndrome, in which ventricular tachycardia (VT) was provoked by high fever, is the first report in a Korean child. The boy had retinoblastoma of his left eye diagnosed at 16 months of age. After chemotherapy, he contracted a catheter-related infection with a high fever up to 41℃ leading to monomorphic VT. This was characterized as having right bundle branch bloc

In the current study, while ex-smoking status was significantly associated with CVD, current smoking status was not. Female ex-smoking status had a higher adjusted odds ratio for CVD than males compared to non-smoking status. An effect of hidden female smoking was also found on the association between smoking status and CVD in Korean adults.

Atopic dermatitis (AD) is a prevalent allergic disease in children that often causes sleep disturbance and which is associated with diminished quality of life and heightened susceptibility to depression and suicidality. In this study, we investigate the relationship between weekend catch-up sleep (WCUS) and mental health in a sample of 71,434 adolescents with AD and 221,057 without AD using multivariate logistic regression analysis. We hypothesized that adolescents with AD experience shorter tot

Atopic dermatitis (AD) has a negative influence on school attendance. We aimed to identify factors associated with school absenteeism in adolescents with AD. We used data from the 3rd to 11th annual Korean Youth Risk Behavior Web-based Survey completed from 2007 to 2015. Survey data were obtained from a stratified, multistage, clustered sample. Participants responded to the question "have you ever been diagnosed with AD?" Factors associated with AD-related school absenteeism (ADSA), which is def

PURPOSE: Prader-Willi syndrome (PWS) is a well-known genetic disorder, and microdeletion on chromosome 15 is the most common causal mechanism. Several previous studies have suggested that various environmental factors might be related to the pathogenesis of microdeletion in PWS. In this study, we investigated birth seasonality in Korean PWS. METHODS: A total of 211 PWS patients born from 1980 to 2014 were diagnosed by methylation polymerase chain reaction at Samsung Medical Center. Of the 211 pa
