Objective: To investigate whether earlier mother’s age at menarche is a risk factor of daughter’s early menarche, obesity, and short stature in young Korean female.Research design and methods: We tested associations between mother’s age at menarche, mother’s adult body size and her daughter’s age at menarche, body size from the data of 6th Korea National Health and Nutrition Examination Survey (KNHANES VI) (2013–2015). We an...

Background: Currently, little information is available on current growth status according to birth weight at gestational age (BWGA) on Korean adolescents. Herein, the current height and weight of Korean adolescents who were born as small for gestational age (SGA) were compared to those of the non-SGA groups.Methods: Data from the population-based nationwide Korean survey 5th Korea National Health and Nutrition Examinatio...

Objective: The present study aimed to evaluate the association of free thyroxine (FT4) and TSH with insulin resistance indices in euthyroid Korean children and adolescents using nationally representative data.Methods: A total of 259 children and adolescents were included in data from The Korean National Health and Nutrition Examination Survey 2015.Results: TSH levels were significantly positively associated with HOMA-IR (β...

Objective: To determine the effect of gonadotropin-releasing hormone agonist (GnRHa) treatment on auxological outcome of Korean boys with central precocious puberty (CPP) and early puberty (EP).Methods: This study included 11 boys with CPP and 8 boys with EP who were treated with GnRHa for at least 2 years at the Pediatric Endocrine Unit of Ajou University Hospital from March 2003 to December 2015. All nineteen boys atta...

Background: Premature thelarche (PT) is a benign, non-progressive condition defined as isolated breast development without the activation of the hypothalamic-pituitary axis. While the pathophysiology of PT remains unclear, increased sensitivity to estrogen may cause PT.Objective and hypotheses: The aim of this study was to investigate the association between polymorphisms in the estrogen receptor alpha (ERα) gene and PT in girls.<p class="abstex...

Background: Congenital hypothyroidism (CH) is the one of the most common preventable cause of mental retardation. Earlier and proper treatment is associated with better intellectual outcomes.Objective and hypotheses: The aim of the present study was to evaluate intellectual outcome of children with diagnosed congenital hypothyroidism (CH) and early onset treatment.Method: We retrospectively reviewed the medical record of 43 childre...

Objective: Obesity is associated with bone age (BA) advancement of unclear etiology. In animal study, insulin may directly modulate skeletal growth. Our objective was to investigate the association with BA maturation and insulin levels in children with overweight and obesity.Methods: In this cross-sectional study of 42 prepubertal children, anthropometric data and hormonal values during oral glucose tolerance test were measured. Subjects were divided int...

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 ...

Background: Familial precocious puberty is defined by the existence of more than one affected member either in the proband generation or in the pedigree. Recently, several gene mutation cause familial CPP is elucidated, gain of function mutations in KISS1 and KISS1R, loss of function mutations in the MKRN3, the feature of familial precocious puberty is not fully understood.Objective: To investigate the clinical characteristics of familial precocious pube...
