Background: Low bone mass during growth may increase risk of fracture. Adequate reference data for bone mineral density (BMD) are needed to identify adolescents with bone deficit.Objective and hypotheses: We aimed to provide normative values and reference curves for BMD in Korean adolescents and young adults.Method: Using the data from Korean Nutrition Health and Nutrition Examination Survey (KNHANES) in 2008–2011, a total of ...

Background: Phthalates are synthetic chemicals produced in extremely large volumes for a wide variety of uses in personal care and consumer products, including building materials, food packaging, medical devices, toys and cosmetics. Though a few studies have shown that concentrations of phthalate metabolites are associated with obesity and insulin resistance in adults, studies in children are limited.Objectives: We studied to examine the associations of ...

Background: Hypertension is the leading cause of cardiovascular disease worldwide and both high and low blood pressures are associated with various chronic disease. Thyroid hormones have profound effects on cardiovascular function, including effects on blood pressure.Objective and hypotheses: Recent studies suggest that early life high blood pressure could be attributed to hypertension in late adulthood. Therefore, we aimed to investigate the association...

Background: The serum 25-hydroxyvitamin D (25OHD) levels are known to be lower in obese children, probably due to sequestration of vitamin D in the adipose tissue. However, there is no consensus on the dose adjustment for vitamin D supplementation in obese children with vitamin D deficiency (VDD).Aims: To compare the response to vitamin D replacement in normal weight vs overweight children with VDD, and to investigate the determinant for increment of 25O...

Introduction: The prevalence of renal anomalies in Turner syndrome (TS) has been reported to vary from 30 to 70%. However, the influence of renal anomalies on renal function and morbidity have been less well investigated. We evaluate the status of renal function and the presence of urinary abnormalities in early adult TS patients.Patients and method: Sixty-three girls with TS, who are attending Pediatric Endocrine Clinics in Busan Paik Hospital, were stu...

Objective: To analyze the genetic cause of congenital hypothyroidism by targeted exome sequencing in pediatric patients with congenital hypothyroidism with thyroid gland in situ.Patient and Method: The study population comprised 20 patients with thyroid gland, who were diagnosed with congenital hypothyroidism at Pediatric Endocrinologic Clinic of Pusan National University Hospital. Targeted exome sequencing was ...

Background: In this study, we aimed to investigate the relationship between single-gender Korean references for non-high-density-lipoprotein cholesterol (non-HDL-C) and metabolic syndrome (MetS) in childhood.Methods: A total of 5,742 Korean children aged 10–18 years who participated in a national survey were included. The subjects were classified into three groups based on single-gender non-HDL-C levels as follows: <120 mg/dl (desirable), &#8805...

Aims: The current study aimed that first morning voided (FMV) urinary gonadotropin measurements could be used as a noninvasive alternative to the gonadotropin-releasing hormone (GnRH) test in the assessment of the hypothalamic-pituitary-gonadal function in children.Methods: In a multi-center study, we compared FMV urinary gonadotropin concentrations with GnRH-stimulated serum gonadotropin levels in 140 girls aged 7–9 years who were evaluated for pub...

Background: Hyperinsulinism/hyperammonemia (HI/HA) syndrome is a form of congenital hyperinsulinism (CHI) caused by a mutation in the GLUD1 gene. It is characterized by hyperinsulinemic hypoglycemia accompanying hyperammonemia.Objective and hypotheses: We report HI/HA syndrome with a 4-month-old male who hypoglycemic seizure.Method: A 4-month-old male infant presented with seizure caused by fasting-induced hypoglycemia. At the time...

Background: GnRH agonist (GnRHa) are able to modify natural course of Central Precocious Puberty (CPP) in girls.Objective and hypotheses: We evaluated the etiology and the effect of GnRHa in Korean CPP boys.Method: Total 29 boys diagnosed for CPP from 2007 to 2012 were included in Ajou University Medical Center. Sellar MRI was performed in 26 of 29 patients (89.7%). CPP was diagnosed on the basis of i) onset evidence of testicular ...
