Background: Hyperglycemia and dyslipidemia are metabolic abnormalities commonly found in type 1 diabetes.Objective and hypotheses: Limited data are available on the relationship between glycemic control and dyslipidemia in patients with type 1 diabetes. We aimed to investigate the incidence of dyslipidemia and its association with glycemic control in adolescents and young adults with type 1 diabetes.Method: This cross-sectional stu...

Objectives: Diabetes in children and young adults is increasing worldwide. However, the study of change in fasting glucose among general pediatric and young adult population was lacking. The aim of this study was to investigate the secular trend of fasting plasma glucose (FPG) levels in non-diabetic Korean youth and young adults and to evaluate the change in the proportion of impaired fasting glucose (IFG).Methods: Study subjects were Korean youth aged 1...

Background: Experimental models suggest that exposure to low dose nonylphenol could induce adiposity and promote adipocyte differentiation in mice. However, studies on the effect of nonylphenol exposure to human obesity have not been adequately studied.Objective: We investigated the associations of serum nonylphenol concentration with adiposity measures in Korean children and adolescents.Me...

Background: During puberty, gray matter (GM) volume decreases and white matter (WM) volume increases in brain. It has been suggested that pubertal hormones may induce some neuroanatomical changes during puberty. Central precocious puberty (CPP) is caused by premature activation of the hypothalamus-pituitary-gonadal axis in inappropriately early age. However, little is known about the differences of brain structure (especially brain volume) in idiopathic CPP. Also the relation ...

Background: The Korean National Health Insurance Service has started reimbursing the cost of continuous glucose monitoring (CGM) in type 1 diabetes (T1D) in 2019. We investigated the effect of CGM use on glycemic control among Korean children, adolescents, and young adults with T1D in a real-world setting.Method: We retrospectively reviewed the medical records of childhood-onset T1D patients aged < 30 years (n</em...

Background, Objective and hypotheses: GX-H9 is a hybrid Fc-based long-acting recombinant human growth hormone (hGH). The safety, tolerability, and PK/PD of single ascending dose in healthy volunteers were assessed to determine GX-H9 doses capable of normalizing IGF-1 level. The PK/PD, safety, efficacy and tolerability of multiple sequential doses of GX-H9 in adult growth hormone deficiency (AGHD) were compared to that of a daily recombinant hGH in AGHD. A Phase 2 study in pedi...

We investigated the reference values of liver enzymes based on cardiometabolic risks among children and adolescents using the Korea National Health and Nutrition Examination Survey (KNHANES). A total of 8,091 subjects aged 10-18 years were included data from 2007-2017. Overall, Aspartate aminotransferase (AST), alanine aminotransferase (ALT), and the AST/ALT ratio varied with sex and age. AST levels tended to decrease with age, but ALT levels had a U-shaped curve, which result...

Purpose: Bisphenol A (BPA) is endocrine disrupting chemicals used to manufacture plastics such as epoxy resins and polycarbonate polymers. BPA has weak estrogenic and strong anti-androgenic effects and has also been linked to disruption of thyroid function in previous studies. This study aims to investigate the relationship between urinary bisphenol A exposure in early childhood and thyroid hormone of pubertal children in Korea.M...

Objective: To analyze the genetic cause of congenital hypothyroidism by targeted exome sequencing in pediatric patients with congenital hypothyroidism with thyroid gland in situ.Patient and Method: The study population comprised 20 patients with thyroid gland, who were diagnosed with congenital hypothyroidism at Pediatric Endocrinologic Clinic of Pusan National University Hospital. Targeted exome sequencing was ...

Hypophosphatasia (HPP) is a genetic skeletal disease caused by loss-of-function mutations of ALPL encoding tissue-nonspecific alkaline phosphatase (TNSALP). The clinical presentation of HPP varies greatly, ranging from stillbirth without bone mineralization to findings in later life, such as delayed walking, short stature, skeletal deformities, bone pain, and pathologic fractures. The diagnosis is based on clinical examination, radiographic findings, biochemical parameters of ...
