Background: Prolactin is a peptide hormone produced by the anterior pituitary gland. Hyperprolactinemia can be caused by stress, but pathological causes of hyperprolactinemia could be due hypothyroidism, medications or hypothalamic/pituitary tumors. It is important to differentiate between the causes of hyperprolactinemia. The best way to accomplish this is via a rest test. One way to accomplish this would be to measure prolactin levels as a part of a hormone ...

Context: Deficiency of 3β-hydroxysteroid dehydrogenase 2 (3βHSD2) causes a very rare form of congenital adrenal hyperplasia (CAH) known as 3βHSD2 deficiency, which is a consequence of biallelic HSD3B2 gene defects. The estimated prevalence is less than 1/1,000,000 live births. Knowledge of comprehensive steroid metabolome patterns in 3βHSD2 deficiency is scarce.Objective: We aimed...

Objectives: Type one diabetes mellitus (T1DM) is an autoimmune disorder that is yet the most common type of diabetes in children and adolescents. Therefore, children and adolescents with T1DM are at increased risk for developing other autoimmune diseases including Graves’ disease. Detection of thyroid abnormalities in children is crucial since thyroid dysfunction can affect growth, pubertal maturation, insulin metabolism and gastrointestinal function. Herein, we reported ...

Background: 5α-Reductase is an enzyme that converts testosterone to dihydrotestosterone (DHT) in peripheral tissues. DHT is responsible for the differentiation of male external genitalia. Mutations in the 5α-steroid reductase type 2 gene (SRD5A2) result in incomplete masculinisation of the external genitalia in subjects with a 46,XY karyotype. The clinical spectrum of a 46,XY individual with 5α-reductase deficiency at birth can range from complete femal...

Introduction: Brain-lung-thyroid syndrome (BATS) is a rare autosomal dominant inherited syndrome that develops due to mutations in the NKX2-1 gene, which is a thyroid transcription factor, and is characterized by respiratory distress in the neonatal period, congenital hypothyroidism, and choreatetosis. Approximately half of affected patients have the complete triad, with 30% affected by the neurological phenotype (motor developmental delay, gait difficulties, choreatetosis, hy...

Introduction: DICER1 syndrome is a pleotropic, autosomal dominant familial genetic tumor predisposition syndrome. DICER1 somatic + germ-line mutations (double hit hypothesis); cystic nephroma; pleuropulmonerblastoma, ovarian sex cord-stromal tumors, multinodular goitre (MNG) are associated with many conditions such as differentiated thyroid cancer, pituitary blastoma. We presented three cases, two of whom were siblings, who had been consulted because of no...

Background and methods: Sellar and suprasellar tuberculomas are extremely rare in children and most often patients present with headache, vomiting, visual disturbances, and hypofunction of the pituitary gland. Here, we report a girl with hypothalamic obesity, that recovers after antituberculosis treatment.Findings: An 11-year old girl presented with headache, fever and anorexia that progressively evolved into an encephal...

Background: Luteinizing hormone stimulating hormone (LHRH) test is the gold standard test in the diagnosis of puberty precocıous (PP). The basal levels of FSH (follicular stimulating hormone) and LH (luteinizing hormone) cannot be always reliable.Objective and hypotheses: To investigate the relation between the LHRH test and basal levels of FSH and LH.Method: Girls with puberty started before the age 8 are investigated. Eighty...

Background: The diagnosis of turner syndrome (TS) must be included in the differential diagnosis of all girls with short stature. Despite overall earlier diagnosis and treatment there still remain patients with TS who present late with delayed puberty. Although growth hormone (GH) is known to increase final height (FH) in girls with TS, little evidence exists on treatment in late-presenting girls.Objective and hypotheses: To assess the effect of late GH ...

Background: According to the latest studies vitamin D has an effect on the production and/or secretion of IGF1 in the liver, but the exact mechanism regulating these relationships has not been thoroughly explained.Objective and hypotheses: Evaluation of the relationship between 25(OH)D and IGF1 levels in the serum of children with GH deficiency (GHD).Method: The study group consisted of 76 GH deficient children qualified for GH the...
