Purpose: Bisphenol A (BPA) is endocrine disrupting chemicals used to manufacture plastics such as epoxy resins and polycarbonate polymers. BPA has weak estrogenic and strong anti-androgenic effects and has also been linked to disruption of thyroid function in previous studies. This study aims to investigate the relationship between urinary bisphenol A exposure in early childhood and thyroid hormone of pubertal children in Korea.M...

Background: Relative adrenal insufficiency (RAI) may be associated with neonatal adrenal hemorrhage (AH).Objective and hypotheses: The purpose of this study was to investigate the usefulness of ultrasonography for detecting AH in steroid treated neonates with RAI.Method: A retrospective analysis of 52 corticosteroid-treated patients with RAI at a neonatal intensive care unit of a tertiary center from January 2006 to April 2014 was ...

Background: Simple goitre (SG) and autoimmune thyroid disease (AITD) are the two most common causes of goiter in children.Objective and hypotheses: The prevalence of thyroid dysfunction, AITD, and SG at the time of goiter diagnosis was investigated. The natural course of SG was studied and factors related to the development of AITD and/or thyroid dysfunction were analysed.Method: A retrospective review of 1,225 patients (1071 femal...

Background: Childhood obesity is a major health concern. Exposure to environmental chemicals may play a role in childhood obesity.Objective and hypotheses: We investigated whether urinary phthalate metabolite concentrations was associated with overweight or obese status in 4-year-old children.Method: Forty-hundred thirteen children born as term, appropriate-for-gestational-age infants (226 males) were included in this study. BMI wa...

Patients with Disorders of sex development (DSD) can present with a large phenotypic spectrum and caused by a number of different genetic defects. Therefore, it is difficult to reach a specific diagnosis using traditional approaches including biochemical analysis and single gene sequencing in a number of patients with DSD. Recently, next-generation sequencing technologies have revolutionized the identification of causative genes with diseases with genetic heterogeneity using m...

Background: Microalbuminuria is usually the earliest sign of diabetic nephropathy. However, it does not always progress to macroalbuminuria,and may regress to normoalbuminuria. Mean HbA1c and HbA1c variability was known to be independent risk factors for microalbuminuria in children with type 1 diabetes.Objective and hypotheses: We hypothesised that both mean and variability of HbA1c could affect the progression to macroalbuminuria in children with type ...

Maturity onset diabetes of the young (MODY) is a rare type of non-autoimmune diabetes mellitus which usually present in young adulthood. An estimated prevalence was 1.2% within the pediatric diabetic population. To date it has been proposed that pathogenic variants in at least 14 genes cause MODY. Among these genes, most cases result from mutations in HNF1A (MODY3), GCK (MODY2), HNF4A (MODY1) and HNF1B (MODY5). The patient is a 13-year-old, previously healthy, nonobese female ...

Purpose: Vitamin D deficiency is thought to be influenced by cardiovascular function and glucose homeostasis, however the potential influence of vitamin D status on insulin resistance, is not well understood. The aim is investigate the correlations between 25-hydroxyvitamin D[25(OH)D] with adiposity assessed by body mass index(BMI), fasting glucose and lipid levels on schoolchildren.Methods: From April 2015 to July 2018,...

Background: Nephrogenic diabetes insipidus (NDI) is caused by inability of renal collecting duct cells to respond to arginine vassopresin (AVP)/antidiurethic hormone (ADH).Objective and hypotheses: The majority of patients (about 90%) have type 1, X-linked recessive form, of NDI caused by mutation in gene encoding the vassopresin V2 receptor. Type 2, autosomal NDI, have the rest 10% of patients. This type is caused by the aquaporin-2 water channel (AQP2)...

Background: The lack of agreement in the definition of vitamin D deficiency may be due to differences in the study populations or in the assays used to measure 25OHD.Objective and hypotheses: The aim of this study is to evaluate the relationship between 25OHD and PTH, and define the level of vitamin D deficiency in a paediatric population.Method: Retrospective medical record of children (age: 0.1–18years, n=193) who v...
