Purpose: Androgen insensitivity syndrome (AIS) is a rare X-linked recessive disorder caused by unresponsiveness to androgen because of mutations in the AR gene. Here, we investigated the clinical outcomes and molecular spectrum of AR variants in patients with AIS attending a single academic center.Methods: This study included 19 patients with AIS who were confirmed by molecular analysis of AR. Clinical features and endoc...

Background: Hypothalamic obesity (HO), defined as abnormal weight gain due to physical hypothalamic destruction, for example due to suprasellar tumours, is characterised by significant hyperphagia, lack of satiety, and rapid weight gain in the first year of hypothalamic insult. HO is not usually responsive to caloric restriction or lifestyle modification, and no pharmacotherapies are specifically approved for treating HO. GLP-1 agonists, which suppress appetit...

Neonatal diabetes mellitus (NDM) is a hyperglycemic status usually diagnosed before first 6 months of life, which is caused by monogenic mutations. INS gene mutation is the second most common cause of permanent NDM, causing misfolding of proinsulin and accumulation in the endoplasmic reticulum, leading to apoptosis of the pancreatic beta cells. We report a case of NDM in a 2-month-old girl with a novel heterozygous mutation of the INS gene, and functional studies to confirm th...

Introduction: Post-marketing surveillance registries provided extensive information about the safety and efficacy of daily growth hormone (GH) therapy during treatment. With the availability of novel long-acting GH (LAGH) therapies, it is important to determine whether the novel molecules or the different pattern of GH exposure lead to changes in the efficacy and safety profile. Therefore, new surveillance registries of LAGH are warranted.<p class="abstext...

This study aimed to evaluate the long-term safety and effectiveness of recombinant human growth hormone (rhGH; Eutropin®, Eutropin®Pen, Eutropin®AQ, and Eutropin®Plus, LG Chem, Ltd.) treatment in Korean pediatric patients. This observational study has been conducted since 2011, and the data were collected up to August 2021 for interim analysis. The incidence rates of all adverse events (AEs) were assessed for safety a...

Background: Pediatric thyroid cancer has characteristics that are distinct from adulthood thyroid cancer. Due to its very low prevalence, little is known about the genetic characteristics of pediatric follicular thyroid cancer (FTC).Methods: We investigated genetic alterations in tumor tissues from 15 patients aged < 20 years (median: 14.3 years; range: 2.4-19.0 years) using multifaceted approaches. Whole-exome seque...

Introduction: Adrenarche refers to the increase in adrenal androgen synthesis. However, process of adrenal androgen production in early childhood remains to be elucidated. The aim of this study was to evaluate changes in adrenal androgen levels and steroidogenic enzyme activities associated with adrenarche using a prospective cohort.Methods: A total of 229 children (124 boys, 52.4%), who had participated in the Envir...

Background: Improved patient and graft survival post-liver transplantation has led to a parallel increase in metabolic syndrome (MS) reported in multiple centres. We aimed to study the prevalence and risk factors of metabolic complications in our paediatric liver transplant (LT) cohort.Methods: This was a retrospective review of the LT database from 1995-2018. We studied the incidence of overweight, obesity (WHO BMI crit...

Backgrounds: Perfluoroalkyl compounds (PFCs) have been suggested as potential thyroid disrupting chemicals. However, previous studies about the associations between PFCs and childhood thyroid function are scarce, and inconclusive. We evaluated the PFC exposure in Korean preschool children, and investigated the temporal relationship with thyroid hormone concentration.Methods: From a prospective the Environment and Develop...

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...
