Background: Management options are limited for the treatment of Graves' disease (GD) in children and adolescents. Antithyroid drugs (ATDs) remain the first-line therapy in patients with GD, despite a high relapse rate. We investigated the clinical characteristics, treatment, the outcome, and predictors of a remission of children and adolescents with GD at a single center.Methods: We retrospectively reviewed the medic...

Purpose: This study aimed to describe gene mutations and growth outcome in patients with 21-hydroxylase deficiencyMethods: Subjects were diagnosed as 21-hydroxylase deficiency by direct Sanger sequencing or multiple ligation-dependent probe amplification analysis and visited Pusan National University Children's Hospital from July 2008 to April 2019.We investigated the genotype, phenotype and growth profiles.<p cl...

Background: CHARGE syndrome is a complex of congenital malformations affecting multiple organ systems caused by mutations in CHD7.Objective and hypotheses: This study was performed to evaluate endocrine dysfunctions including hypogonadotropic hypogonadism, growth hormone deficiency, or hypothyroidism in patients with CHARGE syndrome.Method: Eighteen patients (10 males and 8 females) with CHARGE syndrome were included. A di...

Background: A 3-year-old boy appeared healthy at birth and did not experience any fractures until 12 months of age. Blue sclera, frequent fractures without adequate trauma, nearly normal stature, the absence of dentinogenesis imperfecta, no bony deformity, and no limitation of mobility were characteristics suggestive of OI type I that were observed in the patient. The patient’s mother had blue sclera and a history of frequent fracture episodes until the age of 15 years.</...

Background: Osteogenesis imperfecta (OI) includes a group of disorders with a susceptibility to bone fractures, the presentation ranging from slightly increased fracture frequency to death in the perinatal period.Objective and hypotheses: Autosomal-dominant inheritance with type I collagen biosynthesis defects is the most common, but many autosomal-recessive genes have been previously reported.Method: Whole-exome sequencing was per...

Background: GnRH agonists are a common treatment modality for patients with central precocious puberty.Objective and hypotheses: Danazol-induced precocious puberty rats were used as an animal model to compare the effects of GnRH analogues and to assess combinations of treatment with agonistic and antagonistic GnRH analogues.Method: A 5-day-old female Sprague–Dawley rats were subcutaneously injected with a single dose of 300 &#...

Introduction: Turner syndrome (TS) is caused by monosomy or structural abnormalities of the X chromosome, with a prevalence of out 1/2500 females live birth. Most important clinical features of TS are short stature and gonadal failure. Approximately one third of girls with TS may undergo spontaneous puberty. Here we report a case of a variant TS with breast development.Case report: A 9-year-old girl was referred to our paediatric endocrinology outpatient...

Background: Triglyceride and glucose (TyG) index is significantly associated with higher risk of developing type 2 diabetes mellitus (T2DM). The mechanism of the role of TyG index in the development of T2DM is not clear. There are few studies on the relationship between the TyG index and homeostatic model assessment of insulin resistance (HOMA-IR).Aims: To elucidate the role of the TyG index, studies are needed on the association between...

Background: Perturbation of inflammation is critically linked to nutrient metabolic pathways and obesity-associated complications, such as insulin resistance and type 2 diabetes (T2DM). The S100 family of proteins, including S100A8/A9 (calprotectin), have been implicated in disease pathogenesis and investigated as potential markers of inflammation. In adults, increased circulating levels of calprotectin have been reported in obesity-related chronic low-grade i...

Objective: Prader-Willi syndrome (PWS) is a complex genetic disease associated with hypothalamic-pituitary dysfunction, severe obesity and metabolic dysfunctions. The aim of this study was to describe endocrine and metabolic profiles in PWS children and young adults.We also investigated the differences in clinical outcomes according to genotype.Methods: Data of 64 children and adults with genetically verified PWS aged mo...
