Objective: Central precocious puberty (CPP) is characterized by the development of secondary sexual characteristics before the age of 8 years in girls and 9 years in boys. Early activation of hypothalamic-gonadal axis is influenced by both environmental and genetic factors. Especially, genetic factors have critical role of pubertal progression, but mutations associated with CPP have only been discovered in three genes: KISS1, KISS1R, and MKRN3. The aim of thi...

Background: The growth hormone (GH) stimulation test, which requires multiple blood sampling, should be performed to confirm the diagnosis of growth hormone deficiency because of the pulsatile secretion of GH. In addition to hypoglycemia, L-dopa and arginine, deep sleep is also known as an important stimulator of GH secretion.Objectives: The aim of study was to assess the accuracy and predictive value of the test of post...

Background: Fibrous cortical defects (FCDs) and non-ossifying fibromas (NOFs) are the most common benign lesions of the skeletal system, with an estimated incidence of up to 30% in children and adolescents.Objective and hypotheses: Although their aetiologies are unknown, FCDs and NOFs develop mostly in regions of intense bone growth. We hypothesized that patients with precocious puberty (PP) would have a higher prevalence of FCDs and NOFs than age-matche...

Case presentation: A 23 months-old girl visited the hospital because of fever and left neck mass. She was diagnosed as acute suppurative thyroiditis with piriform sinus fistula. Thyroid sonography showed perithyroidal abscess formation and thyroid scan showed decreased uptake of Tc-99 m pertechnate of both thyroid glands. Magnetic resonance imaging of neck suggested infected 3rd and 4th branchial cyst. And there was tiny fistula between thyroid and piriform sinus on barium eso...

Purpose: The Tanner-Whitehouse (TW) system is the method of choice for skeletal maturity assessment in both clinical practice and auxological research (Tanner et al. 1983), and it has been used to estimate skeletal maturity in groups of children from all over the world. This study aimed on analyzing the characteristic of the RUS maturity of Korea children by evaluating RUS maturity of Korea children using the TW3 method, compared with children in China and Japan<stron...

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: Girls with precocious puberty have high LH levels and bone age was advanced over chronological age by 1 year. Obese children start puberty at an earlier age than non obese children. The mechanisms that cause obese children to grow faster starting from early childhood are not well defined.Objective and hypotheses: We analysed the effects of obesity on luteinising hormone (LH) secretion by using gonadotropin-releasing hormone (GnRH) tests in gi...

Background: The triglyceride glucose (TyG) index is significantly associated with the presence of nonalcoholic fatty liver disease (NAFLD) and is a reliable insulin resistance (IR) surrogate marker. Alanine aminotransferase (ALT) has been commonly used to reflect liver inflammation and liver damage in patients with chronic liver diseases, including NAFLD. Transient elastography (TE) uses pulsed echo ultrasound to measure the hardness of the liver, showing exce...

Background: Congenital hyperinsulinism (CHI) is a disorder causing persistent hypoglycemia due to oversecretion of insulin. Diazoxide, a KATP channel opener in pancreatic beta cells is the treatment of choice, however, the glucose level should be monitored carefully. We report here a case of an infant girl with CHI who was complicated by diabetic ketoacidosis (DKA) during acute febrile illness.Case Report: A 1...

Purpose: Central precocious puberty (CPP) is less common in boys than girls; very little data is reported on long-term effects of gonadotropin-releasing hormone analog (GnRHa) treatment in boys with CPP. The aim of the study was to evaluate the impact of treatment with GnRHa on adult height (AH) and body mass index (BMI) in boys with idiopathic CPP.Subjects and Methods: In 18 boys with confirmed diagnosis of idiopathic C...
