Purpose: Multiple endocrine neoplasia (MEN) is a rare, autosomal dominantly inherited cancer syndrome caused by a mutation in MEN1 or RET gene. Identification of the genetic causes of the MEN is critical because genotype provides information on timing of prophylactic surgery in patients with MEN type 2 who have clinically silent tumors. Therefore, this study investigated clinical phenotype and molecular characteristics of children with MEN in...

Purpose: Type 1 diabetes mellitus (DM) is the most common cause of diabetes in children and adolescents. Prevalence of monogenic DM is estimated for about 1%–5% of all patients with DM. Overlapping clinical features of various forms of diabetes make differential diagnosis challenging. This study was performed to investigate frequency and genetic etiologies of monogenic diabetes in a single academic center.Methods: This study included 466 consecutive...

Background: Isolated gonadotropin-releasing hormone (GnRH) deficiency (IGD) is caused by a deficiency in GnRH production, secretion or action. IGD is a highly heterogeneous disorder with wide phenotypic spectrum including Kallmann syndrome (KS) with anosmia and normosmic idiopathic hypogonadotropic hypogonadism (nIHH). More than 30 different causative genes have been identified in several studies. However, there are no data on the prevalence, clinical characteristics, and mole...

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...

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: 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...

Objective: Prader-Willi syndrome (PWS) is a complex genetic disease associated with hypothalamic-pituitary dysfunction, severe obesity and metabolic dysfunctions. The aim of this study was to describe endocrine and metabolic profiles in PWS children and young adults.We also investigated the differences in clinical outcomes according to genotype.Methods: Data of 64 children and adults with genetically verified PWS aged mo...

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: Growth hormone (GH) treatment requires long-term self-management and optimized recombinant-human growth hormone (r-hGH) prescription. Patient support programs (PSPs) are vital in educating, providing personalised support to caregivers and enhancing patient care to achieve optimal growth outcomes. Nurse-led PSP calls using behavior change techniques (BCTs) and motivational interviewing principles have demonstrated a meaningful behavior change across...

Purpose: Growth hormone (GH) treatment has become common practice in Turner syndrome (TS) to improve final adult height. However, there are only a few studies on the analysis of good responders to GH treatment in TS. The aim of this study is to predict the responsiveness to growth hormone therapy in Turner syndrome.Methods: Among 197 TS patients registered in LG Growth study, 92 patients were excluded because of systemic illness or hypothyroidism. The cl...
