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...

Objective: To analyze the genetic cause of congenital hypothyroidism by targeted exome sequencing in pediatric patients with congenital hypothyroidism with thyroid gland in situ.Patient and Method: The study population comprised 20 patients with thyroid gland, who were diagnosed with congenital hypothyroidism at Pediatric Endocrinologic Clinic of Pusan National University Hospital. Targeted exome sequencing was ...

Objective: We evaluated frequency and risk factors of delayed TSH elevation (dTSH) and investigated follow-up outcomes in the dTSH group with venous TSH (v-TSH) levels of 6–20 mU/L according to whether late preterm infants born at gestational age (GA) 35–36 weeks had risk factors.Methods: The medical records of 810 neonates (414 boys) born at Seoul National University Hospital who had a normal neonatal screenin...

Purpose: We try to analyze the prediction capacity of variable factors to diagnose adrenal insufficiency.Methods: We analyzed clinical and laboratory data of 22 children (Male =13) who have been checked regular dose ACTH stimulation test for suspected symptoms after HSCT (Lymphoid leukemia=5, Myeloid leukemia=9, Non-malignant=8) at the Catholic HSCT center from Feb 2013 to Feb 2017 at Seoul St. Mary’s Hospital. A normal response of ACTH stimulation ...

Purpose: To analyze the effects of clinical and laboratory factors, including insulin-like growth factor (IGF) levels, on the height velocity of normal prepubertal children.Methods: Ninety-five healthy prepubertal children (33 boys, 62 girls) were enrolled. The mean chronological age of the participants was 6.3±1.4 years, with a height standard deviation score (SDS) of −0.88±0.70. IGF-1, IGF binding protein-3 (IGFBP-3), SDS for anthropome...

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...

Objectives: This study aimed to analyze dosing patterns of recombinant human growth hormone (rhGH) (Eutropin® Inj\., Eutropin®Pen Inj., and Eutropin®AQ Inj. for daily injection, and Eutropin®Plus Inj. for weekly injection, LG Chem, Ltd.) using the collected data of the LG Growth Study (LGS) in Korean pediatric patients with growth disorders including growth hormone deficiency (GHD), idiopathic sho...

Objectives: This study aimed to evaluate the safety and effectiveness of rhGH treatment, using specific products (Eutropin®, Eutropin®Pen, Eutropin®AQ, Eutropin®Plus and Eutropin®SPen; LG Chem, Ltd.), in pediatric patients with growth disorders in Korea.Methods: Among the patients who enrolled in LGS (2012–2022, n=5,120), patients received at least one injection of rhGH were included fo...

Background: Studying patients with rare Mendelian diabetes has highlighted molecular mechanisms regulating β-cell pathophysiology. Previous, experimental studies have shown that Class IIa histone deacetylases (HDAC4, 5, 7, and 9) modulate mammalian pancreatic endocrine cell differentiation, function and finally glucose homeostasis.Methods: We performed exome sequencing in one adolescent boy with non-autoimmune di...
