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: Maturity-onset diabetes of the young (MODY) is one of monogenic diabetes caused by a single gene defect. To date, 13 MODY genes have been identified. However, there is big discrepancy in genetic locus between the Asian MODY patients and Caucasian’s one.Objective and hypotheses: We conducted the whole exome sequencing in Korean clinical MODY families to identify novel variants for MODY and compare the result with Caucasian’s one....

Background: Central precocious puberty (CPP) is mostly idiopathic, however, familial cases of CPP and evidence of genetic factors on pubertal timing by genome-wide association studies suggested genetic causes of CPP.Objective and hypotheses: Molecular defects in six genes (KISS1, KISS1R, LIN28A, LIN28B, TAC3, and TACR3) have been known to cause early activation of the hypothalamic-pituitary–gonad...

Background: Craniopharyngioma is the most common parasellar tumor in childhood arising from remnants of Rathke’s pouch. As the hypothalamus plays a vital role in regulation of body weight by balancing energy intake and expenditure, hypothalamic damage by structural lesions is one of the most common causes of hypothalamic obesity. This study investigated prevalence, risk factors for the development of hypothalamic obesity, and consequent morbidities in children following t...

Background: Precocious puberty (PP) is associated with psychological and behavioral problems. However, little is known about body image and psychological features in girls with PP, being treatment with GnRH analogues.Objective and hypotheses: This study aimed to evaluate the perception of body image and self-esteem in girls with PP, were receiving GnRH analogue therapy.Method: From March to August 2013, 82 girls with PP with GnRH a...

Introduction: Serum glycated albumin (GA) is a glycemic marker reflecting the average serum glucose values for the previous 2 weeks. The purpose of this study was to evaluate the usefulness of serum GA as a glycemic index complementing glycosylated hemoglobin (HbA1c) in children and adolescents.Methods: Fifty-four children and adolescents with diabetes mellitus (DM) and 98 children and adolescents without DM (Non-DM) wer...

Introduction: Primary polydipsia is rare during adolescence and is known to be associated with psychiatric disorders or psychological stress. Differential diagnosis includes endocrine, neurologic, renal, and iatrogenic causes.Case Report: A 14-year-old male presented with polydipsia and polyuria that persisted for 6 years. His fluid intake was about 9 liters a day and he woke up for voiding once or two times every night....

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’...
