Introduction: 5-α-Reductase type 2 deficiency (5αRD2) is 46,XY disorder of sex development that requires androgen treatment for normal male external genitalia development. Despite concerns regarding precocious puberty and stunted growth associated with androgen treatment, limited research has been conducted on its effects on individuals with 5αRD2. The present study aims to evaluate the impact of androgen treatment on bone age (BA) and height...

Background: Glycogen storage disease (GSD) is an inherited metabolic defect of metabolic defect of glycogenolysis and gluconeogenesis. Patients with GSDs are associated with endocrine abnormalities such as short stature, delayed puberty, fasting hypoglycemia, and dyslipidemia. In addition, patients with GSD 1b are also at risk of autoimmune hypothyroidism. Therefore, this study was performed to investigate endocrine complications in patients with GSD.<p cl...

Background: Interleukin-6 (IL-6) is a proinflammatory cytokine associated with obesity, insulin resistance, hypertension, and atherosclerosis in adulthood. Few studies have been conducted in healthy young children. We aimed to investigate whether IL-6 levels are associated with cardiometabolic risk factors in healthy 4-year-old children.Methods: From a prospective cohort study named Environment and Development of Children (EDC) cohort, a total of 421 sin...

Background: Hematopoietic stem cell transplantation (HSCT) has improved the prognosis of children with malignant hematologic disease. However, it has had significant adverse effects on the endocrine system, including bone health. Limited studies are available to assess osteoporosis in survivors of adolescents after HSCT.Objective and hypotheses: We investigate the bone mineral density (BMD) and endocrinopathy/treatment factors associated with low BMD in ...

Background: Central precocious puberty (CPP) may result from organic lesions, but it is most frequently of idiopathic origin in girls.Objective and hypotheses: The objective of the study was to identify central nervous system abnormalities in girls with CPP.Method: This retrospective study was performed in 3-tertiary care hospitals between 2005 and 2015. During this period, 200 girls with CPP performed brain magnetic resonance imag...

Background: The Toll-like receptors (TLRs) are germline-encoded receptors that play an essential role in initiating the immune response against pathogens.Objective and hypotheses: In this study, we assess the association of TLR polymorphism with autoimmune thyroid disease (AITD) in Korean children.Method: Seven Toll-like receptor genes (TLR-1, -2, -3, -4, -5, -6, -9) including 15 single-nucleotide polymor...

Background: South Korea is one of the adequate or excessive iodine nutritional state countries and high-iodine intake is related to papillary thyroid cancer. The prevalence of thyroid cancer of South Korea has increased and the proportion of thyroid papillary cancer has increased as 97.9–98.3% in 2010. Childhood thyroid cancer is rare, and the prevalence of thyroid cancer in pediatric population was reported as 20–26% of thyroid nodules worldwide. However, there have...

Background: KiSS-1 and its product, kisspeptin is necessary for puberty onset and proper adult gonadal function due to its stimulatory effect on the secretion of gonadotropin-releasing hormone (GnRH). Although the pathophysiological importance of KiSS-1 and kisspeptin is well known, the developmental patterns of expression of KiSS-1 genes and serum level of kisspeptin have not been explored to date.Objective and hypotheses: We report herein the expressio...

Background: Retinol binding protein 4 (RBP4) and adiponectin are known to be related with insulin resistance and type 2 diabetes.Objective and hypotheses: This study was aimed at investigating (RBP4) and adiponectin secretion in obese Korean children and adolescents with newly diagnosed type 2 diabetes (T2DM).Method: Nine obese children and adolescents with newly diagnosed T2DM (DM group) and ten obese age-matched subjects without ...

Background: Nesfatin-1, a recently discovered anorexigenic neuropeptide, seems to play an important role in hypothalamic pathways regulating food intake and energy homeostasis.Objective and hypotheses: The aim of this study is to evaluate the relation of serum nesfatin-1 level with anthropometric and metabolic parameters in children and adolescents.Method: This study included 78 Korean children and adolescents (42 obese/overweight ...
