Background: Type 1 diabetes is characterised by destruction of islet β cell by autoimmune insulitis and islet cell apoptosis. This study analysed the microRNA 125b how to regulate pancreatic β-cells dysfunction, aiming to elucidate the association between miRNA125b and type 1 diabetes.Objective and hypotheses: Recent study indicate miRNA may have role in the development of type 1 diabetes, so this study analyse the miRNA expression profile in t...

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: Hyperuricaemia has been associated with increased risk of metabolic syndrome in adults and children. Elevation in serum uric acid (SUA) is hypothesized to be a critical initiator of the development of essential hypertension. The exact relationship between SUA and blood pressure (BP) has not been established in the pediatric population. We conducted a systematic review to evaluate the association between SUA and BP in well, obese/overweight and hype...

Introduction: Deficient anterior pituitary with variable immune deficiency (DAVID) syndrome is a rare condition characterized by symptomatic ACTH deficiency and primary hypogammaglobulinemia, caused by a heterozygous mutation in the NFKB2 gene (MIM#164012) on chromosome 10q24. We report the novel mutation of the NFKB2 gene in a Korean boy presenting with gait disturbance, calf pain, and abnormal thyroid function test.<s...

Background: There is a link between congenital hypothyroidism (CH) and neurodevelopmental abnormalities, but no longitudinal studies have yet identified reliable quantifiable measures.Purpose: To evaluate associations between CH and abnormalities in neurodevelopment and growth, and identify the timing of these abnormalities and the best time for intervention.Methods: Data from the ...

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...

Purpose: Patients with mixed gonadal dysgenesis (MGD) and ovotesticular disorders of sex development (DSD) usually present with asymmetric gonads. Differential diagnosis of these conditions is based on karyotype and pathological findings of gonads. However, it is difficult to determine sex of rearing and to predict long-term outcomes. This study investigated the clinical features, karyotype, sex of rearing, and pubertal outcomes of patients with MGD and ovotesticular DSD.<...

Thyroid nodules in children are less common than adults. However, pediatric thyroid nodules have higher rate of malignancy compared with adults, and also have increased risk of metastasis and recurrence. In this study, we analyzed clinical features, laboratory findings, and thyroid ultrasound (US) of children with thyroid nodules to determine predictive factors of thyroid cancer. Total 268 patients under 18 years of age with thyroid nodule whom visited Severance Children’...

Background: Congenital Hyperinsulinism in Infancy (CHI) is characterised by inappropriate insulin release. We currently attribute hypoglycaemia to β-cell dysfunction because of defects in the ion channel genes ABCC8 or KCNJ11. However, the CHI pancreas is also associated with inappropriate expression of foetal-like transcription factors and enhanced cell proliferation.Hypothesis: As the CHI pancreas bears similarities to the foetal pancreas, we hypo...

Background: Congenital hyperinsulinism in infancy (CHI) is associated with inappropriate insulin release from β-cells. This is causally linked to defects in the ion channel genes ABCC8 and KCNJ11 regulating insulin, but little is known about the metabolic support for sustained insulin exocytosis.Objective and hypotheses: We hypothesised that inappropriate insulin release in CHI would require sustained ATP generation by enhanced mit...
