Background: Metabolic control is important in prevention and delay of microvascular and macrovascular complications of type 1 diabetes mellitus (DM). Psychological disorders and, a lack of motivation may negatively affect metabolic control. Therefore, motivational and psychological support can be needed as a part of medical treatment to improve metabolic control in patients with type 1 DM.Objective and hypotheses: To investigate the impact of reward-base...

Introduction: Pituitary stalk interruption syndrome (PSIS) is a rare congenital abnormality of the pituitary gland. Perinatal injuries, defective organogenesis or rare mutations of HESX1, LHX4, OTX3 and SOX3 are proposed to be the cause of PSIS in familial cases. It is characterized by the triad of a very thin or interrupted pituitary stalk, an ectopic (or absent) posterior pituitary and hypoplasia or aplasia of the anterior pituitary. Typical features are tertiary hypothyroid...

Introduction: Vitamin D resistant rickets type II (VDDR-II) is a disease with a difficult treatment developed as a result of mutations in VDR gene. Despite high dose active vitamin D and oral calcium treatments, sufficient recovery cannot be achieved mostly. Successful results with intravenous calcium infusion that is an alternative treatment have been reported; however, serious restrictions and complications such as hospitalization, catheter infection, thrombosis, skin necros...

Introduction: It has been suggested that adipokines found in breast milk and may be effective in early growth of infants.Purpose: It was aimed to evaluate the relationship between total ghrelin (TGh) and nesfatin-1 levels in breast milk with anthropometric measurements in the first 4 months of life in infants with small for gestation age (SGA) showing fast growth pattern.Method: A total of 20 SGA and 20 control infants with appropr...

Background: Swyer syndrome (46,XY pure gonadal dysgenesis) is a rare disorder, which is characterized by female phenotype, female internal genitalia and fibrotic and primitive gonads. Classically, breast development and menstruation are absent due to hypergonadotropic hypogonadism.Objective and hypotheses: To our knowledge, three cases of Swyer syndrome with spontaneous breast development have been reported so far. In these reports, breast development wa...

Background: STAT5B deficiency is characterized by severe postnatal growth failure, low IGF1, elevated levels of GH and prolactin, and immunodeficiency. To date, only ten patients with seven different mutations have been described.Objective and hypotheses: Describe clinical characteristics of a novel homozygous frameshift mutation in STAT5B.Results: A 17-year-old female was referred for proportionate short stature and prima...

Background: Partial androgen insensitivity syndrome (PAIS) typically presents with micropenis, penoscrotal hypospadias, bifid scrotum with descending or undescending testes and gynecomastia. It is x-linked recessive disease resulting from mutations in androgen receptor (AR) gene.Objective and hypothesis: To present clinical characteristics of a novel mutation in the AR gene in an adolescent boy with PAIS who presented with gynecomastia ...

Background and objective: The first and rate-limiting step of steroidogenesis is the conversion of cholesterol to pregnanolone which is catalyzed by the P450scc side chain cleavage enzyme (encoded by CYP11A1 gene-SCC). Homozygous recessive mutations of the CYP11A1 gene cause a global steroid hormone deficiency thereby disorders of sexual development in 46, XY individuals with a variable phenotype depending on the mutation characteristics. About 60 cases of SCC...

Introduction: An activating mutations in the ABCC8 gene cause both transient and permanent neonatal diabetes mellitus (DM) or MODY 12. In relation to the variant in the ABCC8 gene, patients may also present with either neonatal hyperinsulinism and/or DM later in life. Besides, the same variant can cause different phenotypic features among family members. Response to the sulfonylurea treatment may vary between patients.<...

Introduction: Heterozygous loss-of-function mutations in the glucokinase (GCK) gene cause MODY 2. Conversely, homozygous loss-of-function mutations in the same gene give rise to permanent neonatal diabetes mellitus (DM). Previously, two patients diagnosed with DM in adolescence and had homozygous GCK mutations were reported. Variants in these patients have been shown to exhibit inactivated kinetics that are indistinguishable from neonatal ons...
