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...

Background: Leptin is mainly produced by adipocytes. In animal and human, it is a potnet anorectic and increases in obesity. Some reported that precocious puberty is prevelent in children with obesity.Objective and hypotheses: This study was done to see the changes of blood leptin levels in both obese and non-obese children with early puberty or precocious puberty.Method: Study patients consist of 325 children with early puberty or...

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: The lack of agreement in the definition of vitamin D deficiency may be due to differences in the study populations or in the assays used to measure 25OHD.Objective and hypotheses: The aim of this study is to evaluate the relationship between 25OHD and PTH, and define the level of vitamin D deficiency in a paediatric population.Method: Retrospective medical record of children (age: 0.1–18years, n=193) who v...

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 ...

Purpose: Both timing of menarche and growth patterns have changed with time. Menarche is supposed to important role in pediatric linear growth. This study is aimed to investigate the relationship between the timing of menarche and pubertal growth, specifically to analyze when menarche occurs related to the pubertal growth spurt, and how the pubertal height gain is related to the timing of menarche.Method: From January 20...

Pituitary stalk interruption syndrome (PSIS) is a rare congenital pituitary anatomical defect with endocrine abnormalities. The triad of this syndrome comprises thin or interrupted pituitary stalk, absent or ectopic posterior lobe, and hypoplastic or aplastic anterior pituitary lobe. We diagnosed a 16-year-old female patient with combined pituitary hormone deficiency (CPHD) due to PSIS. The patient complained of chronic fatigue and was Tanner stage 1 with no signs of puberty. ...

Backgound: Cleidocranial dysplasia (CCD) is a rare genetic disorder characterized by skeletal abnormalities affecting various parts of the body, including the skull, clavicles, and long bones. The responsible gene is RUNX2 which plays a crucial role in the development of bone and cartilage. Sometimes growth hormone deficiency (GHD) can be associated with short stature in CCD.Case: A female patient was brought to...

Purpose: Gonadotropin-releasing hormone (GnRH) analog is the first-line treatment with precocious puberty happens before age 8 in girls. This study is aim ed to investigate the relationship between height gain and other factors, specifically to analyze validated tool for predicting adult height for precocious puberty or early puberty.Method: From January 2022 to June 2022, 32 girls with central precocious puberty who vis...

Background: Gonadotropin-releasing hormone agonist (GnRHa) treatment is widely used for central precocious puberty (CPP). Although some authors found increases in body mass index (BMI) in girls after GnRHa treatment, most studies reported no significant difference in BMI in girls during and after treatment. However, few studies have investigated changes in BMI in boys with CPP during and after GnRHa treatment. Hence, we aimed to evaluate the effects of GnRHa t...
