Background: Isolated gonadotropin-releasing hormone (GnRH) deficiency (IGD) is caused by a deficiency in GnRH production, secretion or action and 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. FGFR1 mutations have been identified in about 3–10&#3...

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...

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: As the survival rate for pediatric cancers increases significantly with advances in treatment modalities, long-term endocrine complications have also risen. This study investigated the frequencies and risks of endocrine sequelae of childhood cancer survivors after hematopoietic stem cell transplantation (HSCT).Methods: This study included 200 pediatric patients who underwent HSCT. Clinical and endocrinological f...

Background: Leptin, ghrelin, and nesfatin-1 are peptide hormones which regulates food intake, energy homeostasis and growth hormone synthesis.Objectives: To evaluate the relationship between leptin, ghrelin and nesfatin-1 with catch-up growth (CUG) in children born small for gestational age (SGA).Methods: A total of 67 children were included; 34 children born SGA without CUG, 17 ch...

Background: Small for gestational age (SGA) children are defined by birth weight and/or length at least 2 standard deviations (S.D) below the population mean for gestational age. Up to 90% of these infants experience catch-up growth within the first two years of life; however, 10-15% fail to do so, remaining short at age 2 (SGA-SS). The etiology of failure to achieve catch-up growth remains largely unknown.Methods: This ...
