Background: The increasing number of transgender adolescents presenting in early puberty requires to investigate the effects of long-term puberty suppression and gender-affirming hormones (GAH) on body composition and metabolism. Clinical studies have ethical and practical limitations. A preclinical mouse model may be helpful to gain mechanistic insights.Methods: Prepubertal (4week-old) female mice were treated with the ...

Background: Transgender individuals increasingly present at gender services in childhood. Consequently, to suppress pubertal development, more adolescents are long-term exposed to gonadotropin-releasing hormone analogues (GnRHa), from onset of puberty until start of gender-affirming hormones (GAH), around 16 years. Prolonged GnRHa may compromise bone health more than shorter-term treatment. If earlier start of GAH, when psychologically indicated, may partially...

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: 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: Ox in a dose of 0.03-0.05 mg/kg per day in addition to GH treatment significantly increases adult height in TS more than GH alone. To date, the long term effects of Ox in childhood on bone mineral density (BMD) in adulthood are unknown.Methods: This is a follow-up study of a previous randomized controlled trial, performed in the Netherlands. In the original trial, 133 girls were treated with GH. Placebo (Pl...

Objectives: This study aimed to evaluate the long-term safety and effectiveness of recombinant human growth hormone (rhGH) (Eutropin® Inj.., Eutropin®Pen Inj., Eutropin®AQ Inj., and Eutropin®Plus Inj., LG Chem, Ltd.) based on the interim analysis of a 7-year accumulated data of the LG Growth Study (LGS) in Korean pediatric patients with growth disorders including growth hormone deficiency (GHD), T...

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 ...

Objectives: This study was performed to evaluate effectiveness on near-adult height (NAH) and safety of recombinant human growth hormone (rhGH) (Eutropin® Inj., Eutropin®Plus Inj., Eutropin®AQ Inj., LG Chem, Ltd.) treatment in children with growth hormone deficiency (GHD) and Turner syndrome (TS).Methods: The LG Growth Study (LGS) is a multicenter, long-term, observational study designed to evaluate the lon...

Background: Patients born small for gestational age (SGA) with additional syndromic features to short stature are likely to present with genetic causes.Aim: To perform a clinical and genetic-molecular investigation of a group of syndromic SGA patients without catch-up growth.Methods: We selected 118 patients born SGA [birth weight and/or length standard deviation score (SDS) ≤−2 for gestational age] without catch-up gro...

McCune-Albright syndrome (MAS) is a rare disease defined by the triad of precocious puberty (PP), café au lait spots, and fibrous dysplasia (FD). There are only a few patients with MAS in Korean because of the rarity of this disease. We reported the various clinical and endocrine manifestations and genetic analysis of 14 patients with MAS in Korea. It is a retrospective cohort study of patients’ clinical data including about peripheral PP, FD. Also, treatment experie...
