Background: The phenotypic manifestations in the 45,X/46,XY karyotype is diverse and there are challenges in management due to this diversity.Objective and hypotheses: The aim of this study was to describe the clinical spectrum of 45,X/46,XY mosaicism and variants diagnosed in childhood.Method: A retrospective review of 20 patients with 45,X/46,XY (n=7) and its variants ((45,X/46,X,der(Y) (n=12)) and 46,X,der(X),t...

Background: Obesity is a well-recognized complication of craniopharyngioma. Increased hypothalamic involvement (HI) by the tumour and accordant treatment has been associated with greater obesity. Changes in hypothalamic control of the autonomic nervous system (ANS) have been implicated in the development of hypothalamic obesity however, long term changes in the ANS have not been assessed.Objective and hypotheses: We aimed to evaluate ANS activity using h...

Background: Hematopoietic stem cell transplantation (HSCT) recipients are at risk of endocrine complications as a result of chemotherapy and radiation therapy. Development of diabetes mellitus (DM) after HSCT is less frequently reported compared with other complications.Objective and hypotheses: We investigated clinical features of newly diagnosed DM after HSCT for treatment of childhood leukemia.Method: Between April 1999 and Marc...

Background: A subset of central obese but normal weight individuals has been identified, who harbor potentially increased risks for development of MS despite a normal BMI.Objective and hypotheses: We try to evaluate metabolic syndrome (MS) components of normal weight central obese adolescents in Korea stratified by waist-to-height ratio (WHR).Method: This is a cross-sectional study. Data were obtained from the Korean National Healt...

Background: In adolescents, as much as 51% of peak bone mass is accumulating and reaching 40% of bone mineral density (BMD) of adults. There are inconsistent reports on the associations between birth weight (BW) and bone mineral contents (BMC) in adolescents.Objective and hypotheses: We try to investigate the association between BW and BMC in adolescents.Method: Dual-energy x-ray aborptiometry assessment (DXA) of 10–18 adolesc...

Background: Microalbuminuria is usually the earliest sign of diabetic nephropathy. However, it does not always progress to macroalbuminuria,and may regress to normoalbuminuria. Mean HbA1c and HbA1c variability was known to be independent risk factors for microalbuminuria in children with type 1 diabetes.Objective and hypotheses: We hypothesised that both mean and variability of HbA1c could affect the progression to macroalbuminuria in children with type ...

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: Elevated serum uric acid (UA) levels are associated with metabolic syndrome (MS), cardiometabolic risk factors (CMRFs) and non-alcoholic fatty liver disease (NAFLD) in adults. However, little is known about usefulness of UA to predict MS in adolescents. As the prevalence of obesity among pediatric population has been increasing, it is important to know the factors associated with the CMRFs to prevent future development of diabetes and cardiovascular disease.<p ...

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...
