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...

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: KiSS-1 and its product, kisspeptin is necessary for puberty onset and proper adult gonadal function due to its stimulatory effect on the secretion of gonadotropin-releasing hormone (GnRH). Although the pathophysiological importance of KiSS-1 and kisspeptin is well known, the developmental patterns of expression of KiSS-1 genes and serum level of kisspeptin have not been explored to date.Objective and hypotheses: We report herein the expressio...

Thyroid nodules in children are less common than adults. However, pediatric thyroid nodules have higher rate of malignancy compared with adults, and also have increased risk of metastasis and recurrence. In this study, we analyzed clinical features, laboratory findings, and thyroid ultrasound (US) of children with thyroid nodules to determine predictive factors of thyroid cancer. Total 268 patients under 18 years of age with thyroid nodule whom visited Severance Children’...

Background: Rathke’s cleft cyst (RCC) is a benign, sellar or suprasellar lesion arising from the remnants of Rathke’s pouch that have failed to disappear in the normal development of the embryo. Patients with RCCs are mostly asymptomatic but can also exhibit various symptoms related to pituitary insufficiency. With increasing interest on endocrinology disorders of children or adolescents, the prevalence of RCCs is also on the rise. However, the studies on children or...

Background: The achievement and maintenance of normoglycemia is one of the most important goals to prevent both short and long-term complications in type 1 diabetes mellitus (T1DM). As carbohydrate acts as the primary macronutrient affecting postprandial glycemic response, carbohydrate counting is crucial in adjusting prandial insulin doses to preserve postprandial blood glucose within normal limits. The purpose of this study is to examine the effect for carbo...

Background: Glucocorticoids play a major role in the treatment of lymphoblastic lymphoma. However, supraphysiological glucocorticoid therapy may cause the secondary adrenal insufficiency.Presentation of case: A 11-year-old boy with T cell lymphoblastic lymphoma, treated according to COG A5971 protocol, experienced sudden onset of tremor and general weakness in the first day after tapering 28 days of glucocorticoid therapy. He had a moon face and pigmenta...

Background: The incidence of type 1 diabetes mellitus (T1DM) in children and adolescents has increased worldwide. However, the epidemiology of T1DM among Korean children has not been reported since 2001.Objective and hypotheses: We therefore investigated the incidence of T1DM in Korean children and adolescents in 2012–2013 and compared it with data from 1995–2000.Method: Data were obtained from the National Health Insuran...

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...
