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...

We investigated the reference values of liver enzymes based on cardiometabolic risks among children and adolescents using the Korea National Health and Nutrition Examination Survey (KNHANES). A total of 8,091 subjects aged 10-18 years were included data from 2007-2017. Overall, Aspartate aminotransferase (AST), alanine aminotransferase (ALT), and the AST/ALT ratio varied with sex and age. AST levels tended to decrease with age, but ALT levels had a U-shaped curve, which result...

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...

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...

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...

Purpose: We investigated the prevalence of subclinical hypothyroidism (SCH) and its risk factors in prepubertal children at age 6. We also evaluated the prevalence of thyroid nodule or cyst and its relationship with SCH in prepubertal children.Methods: From the Environment and Development of Children (EDC) cohort study, 458 prepubertal children (243 boys, mean 5.8 years) who visited at age 6 were included in this study. Serum concentrations of free thyro...

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: 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...

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...
