Background: Hypoparathyroidism may manifest either as an isolated disorder or as a component of a more complex syndrome. Molecular genetic studies indicate that mutations in PTH, CASR, GCM2 and GNA11 are causes of isolated hypoparathyroidism (IH) and mutations in GATA3, TBCE, FAM111A, AIRE and TBX1 are associated with different complex syndromes with hypoparathyroidism.Objec...

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: The incidence of type 1 diabetes mellitus (T1DM) in children and adolescents has increased worldwide. However, the epidemiology of T1DM among Korean children has not been reported since 2001.Objective and hypotheses: We therefore investigated the incidence of T1DM in Korean children and adolescents in 2012–2013 and compared it with data from 1995–2000.Method: Data were obtained from the National Health Insuran...

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 &#...

Background: The use of GnRHa in central precocious puberty is known to slow puberty progression, subsequently prevent early menarche, and attenuate the height loss by advanced skeletal maturation. But enhancing the final height was so controversial that an additional approach has been used.Objective and hypotheses: To investigate the age of menarche, and the height outcomes in central precocious girls treated with GnRHa (n=61) or combined GH (<e...

Background: GNRH agonist (GnRHa) has been widely used for decades to treat in patients with central precocious puberty (CPP). There are severe studies concerning changes in body composition in CPP patients following GnRHa treatment, but the results are inconsistent.Objective and hypotheses: The aim of this study was to investigate the change of BMI in children treated with GnRHa for 2 years. Also, the present study was performed to assess whether BMI aff...

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...

Objectives: We investigated the trajectories in hemoglobin A1C (A1C) levels among transition-aged patients (age from 15 to 22 years) with type 1 diabetes (T1D).Methods: Among the patients diagnosed with type 1 diabetes in pediatric age between 2001 and 2013 in Seoul National University Children’s Hospital, 119 patients (54 males and 65 females) with a diagnostic age for under 14 and measurement of A1C at least once...

Background: The diagnosis of growth hormone deficiency (GHD) requires the subnormal responses to two provocation tests. This study evaluated the value of the growth hormone provocation test using arginine and insulin-induced hypoglycemia to diagnose growth hormone deficiency (GHD).Method: This study included 294 children with short stature (136 girls and 158 boys) who underwent a growth hormone provocation test using the...
