Introduction: The intellectual outcome in children with congenital hypothyroidism detected by neonatal screening is generally good. The aim of this study was to evaluate the intellectual outcome in patients with congenital hypothyroidism at childhood and to identify factors that may affect intellectual development.Methods: The intelligence quotient (IQ) of 126 patients with congenital hypothyroidism was evaluated at childhood using the Korean Wechsler In...

Introduction: Hypophosphatasia (HPP) is a rare autosomal recessive or dominant genetic disorder characterized by the abnormal development of bones and teeth and deficiency of tissue non-specific alkaline phosphatase activity. These abnormalities occur due to defective mineralization, the process by which bones and teeth take up minerals such as calcium and phosphorus. The specific symptoms can vary greatly from one person to another, sometimes even among membe...

Background: Hyperinsulinism is a common cause of persistent hypoglycaemia in infant. Insulin secretion from pancreatic β-cells is unregulated and inappropriate for the level of blood glucose, causing glucose into the insulin-sensitive tissues, such as the muscle, liver and adipose tissue, leading to hyperinsulinaemic hypoglycaemia. But congenital portosystemic shunt, a rare vascular malformation, can cause hyperinsulinaemic hypoglycaemia rarely because glucose from portal...

The aim of this study was to investigate that exposure metabolites of phthalate one of the endocrine disruptors might be different in sex and might have influenced from obesity and insulin resistance in Korean children and adolescents. Nationwide data of 551 subjects aged 8-15 years (boys 281 and girls 270) who were included the study from 2010-2011. Subjects were grouped by sex and BMI percentile (normal: BMI<85p; overweight: 85P≤BMI<95p; obese: ≥95p). We...

Purpose: Childhood obesity epidemic leads an interest of pre-stage of hypertension; higher/elevated blood pressure (BP) status which BP numbers are lower than the criteria for diagnosing hypertension. In 2017, the clinical practice guidelines for pediatric BP management were published separately by Endocrine Society (ES) and American Academy of Pediatrics (AAP). The aims of this study are to evaluate the prevalence of elevated blood pressure (EBP) including hy...

Background: The use of GnRHa in central precocious puberty is known to slow puberty progression, subsequently prevent early menarche, and attenuate the height loss by advanced skeletal maturation. But enhancing the final height was so controversial that an additional approach has been used.Objective and hypotheses: To investigate the age of menarche, and the height outcomes in central precocious girls treated with GnRHa (n=61) or combined GH (<e...

Background: Endocrine-disruptor compounds (EDCs) like phthalates and bisphenol A (BPA) can have long term effect on children's physical growth. Studies have reported that effect of EDCs exposure on concurrent physical parameters like weight. But there is a knowledge gap with regards to long term effects of EDCs exposure on children's physical growth. Thus, in this study we evaluated the prenatal exposure of EDCs: BPA and phthalates and their influence ...

Background: Interleukin-6 (IL-6) is a proinflammatory cytokine associated with obesity, insulin resistance, hypertension, and atherosclerosis in adulthood. Few studies have been conducted in healthy young children. We aimed to investigate whether IL-6 levels are associated with cardiometabolic risk factors in healthy 4-year-old children.Methods: From a prospective cohort study named Environment and Development of Children (EDC) cohort, a total of 421 sin...

Objective: To investigate whether the early-life overweight/obesity trajectory from ages 2, 4, to 8 affects insulin resistance (IR) in 8-year-old prepubertal children.Methods: From the Environment and Development of Children (EDC) cohort, 262 prepubertal children (147 boys and 115 girls) who visited Seoul National University Children’s Hospital for anthropometric measurements at ages 2, 4 and 8 were included. At ag...
