Background: Humans are exposed to a variety of endocrine disruptors (EDs), including phthalates and phenol substitutes, in daily life. Previous studies have suggested the association between individual EDs and the risk of obesity, however, studies on the effects of multiple EDs have been extremely limited. We investigated the associations of urinary 12 phthalates, 3 polycyclic aromatic hydrocarbons, and 26 phenol substitutes with adiposity measures in Korean girls.<p class...

Background: Cushing disease defined as hypercortisolism due to pituitary adrenocorticotrophic hormone (ACTH) secreting adenoma is a very rare disease, especially in childhood and adolescence. The purpose of this report is to follow up Cushing disease patient who presented with osteoporosis, rapid weight gain, decreased growth rate, and relapsing pituitary adenoma after transsphenoidal adenomectomy (TSA).Case: A 17-years-old boy visited our hospital for e...

Introduction: Encephalocraniocutaneous lipomatosis (ECCL) is a rare neurocutaneous syndrome characterized by unilateral lipomatosis and ipsilateral neurologic/ophthalmic malformation. Jaffe–Campanacci syndrome (JCS) is characterized by the association of café-au-lait spots, axillary freckles, multiple non-ossifying fibromas of the long bones and jaw. Both of ECCL and JCS was associated neurofibromatatosis type 1. We had a case of GH deficiency with combined ECCL and ...

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: Acquired QT prolongation can be caused by electrolyte abnormality, myocarditis, cerebrovascular disease, drug intoxication and hormonal disorders such as hypopituitarism, hypothyroidism, and adrenal insufficiency.Case presentation: We describe a 14-year-old boy with hypopituitarism after trans-sphenoidal surgery (TSS) due to suprasellar mass who manifested bradycardia and QT prolongation on electrocardiogram. This subject complained of blurre...

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...

Hypochondroplasia (HCH) is an autosomal dominant inherited skeletal dysplasia with abnormal growth pattern and inadequate pubertal growth spurt. Achondroplasia and HCH have many similar phenotype, however, HCH show the mildest phenotype among FGFR3-associated skeletal dysplasia, and the radiologic findings are usually so subtle. We investigated to evaluate clue for the hypochondroplasia, and clinical and genetic characteristics of eleven Korean patients with HCH. We a...

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...
