Background: Transient elastography (TE) uses pulsed echo ultrasound to measure the hardness of the liver, showing excellent accuracy in the assessment of fibrosis, and is considered a useful test in nonalcoholic fatty liver disease (NAFLD). Ultrasound fatty liver indicator (US-FLI) is proposed as a non-invasive, semi-quantitative method for predicting hepatitis in children with NAFLD and may reflect the severity of liver histological changes. US-FLI ≥4 or 6...

Introduction: C-type natriuretic peptide (CNP, NPPC gene) and its receptor, natriuretic peptide receptor B (NPR-B, NPR2 gene), is critical for endochondral ossification in growth plate. Biallelic NPR2 mutations are known as acromesomelic dysplasia, type Maroteaux which is characterized by severe short stature. A monoallelic NPR2 mutation has been suggested to mildly impair long bone growth.Obje...

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...

Turner syndrome is the most common chromosomal disorder in girls. They present classically short stature and delayed puberty. Turner girls with 45,X karyotype show normal female external genitalia. But Turner patients containing 45,X/46,XY mosaicism, or Sex-determining Region Y(SRY) gene may have mixed gonadal dysgenesis with various external sexual differentiation or pure gonadal dysgenesis. Existence of Y chromosome particles in Turner syndrome implies that they have risk of...

Turner syndrome(TS) is a chromosomal disorder which occurs in 1/2500 - 1/3000 among female live births, characterized by short stature, pubertal failure and cardiac defects. Mosaicism of 45X/47XXX is extremely rare and accounts for 1.7% of the TS cases. TS with 45X/47XXX is more likely to have spontaneous puberty. The case we present herein is a 13-years old girl who was admitted to Chuncheon sacred heart hospital due to severe anemia. She was diagnosed with Turner syndrom...

Purpose: Central precocious puberty (CPP) is less common in boys than girls; very little data is reported on effect of gonadotropin-releasing hormone analog (GnRHa) treatment in boys with CPP. The aim of the study was to evaluate growth changes in boys with CPP and early puberty (EP) treated with GnRHa therapy for 1 year.Subjects and Methods: In 60 (39 CPP and 21 EP) boys with confirmed diagnosis of CPP and EP, auxological (height, height standard deviat...

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: Nutrition is an important factor to regulate reproductive function. Some studies showed that high fat diet (HFD) may influence to puberty onset and irregular estrous cycles in the female rats. However, underlying regulation mechanism of nutrition on pubertal maturation and reproductive function is not well-known. Kisspeptin and neurokinin B (NKB) are an essential factor for regulation of pubertal development.Objective and hypotheses: In this ...

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...
