Introduction: Short stature is a common manifestation of Noonan syndrome (NS). GH deficiency, GH insensitivity, and neurosecretory dysfunction have been reported in the literature. The optimal GH treatment for NS is still controversial. In this study, we aimed to evaluate the growth characteristics in addition to clinical features of NS, and the growth response to GH treatment by using a nationwide registration system.Material and methods: Children and a...

Introduction: DAX1 (NROB1) mutation, that is among the causes of primary adrenal insufficiency; is revealed with X-linked congenital adrenal hypoplasia and hypogonodotropic hypogonadism. Growth hormone (GH) deficiency is not common in affected individuals. In the literature, there are few cases of GH treatment . growth hormone therapy in two cases with DAX1 gene mutation were evaluated in clinical features and treatment responses.<strong...

Objectives: Type 1 diabetes mellitus (DM) is an autoimmune disease caused by the destruction of pancreatic beta cells. The frequency of Type 1 DM is increasing, and the highest incidence rate is in children under 5 years of age. It is estimated that children under the age of five will develop approximately 70% of the cases under the age of 15, with an increased incidence.In our study, we aimed to evaluate the demographic, clinical an...

Introduction: A rare cause of diabetes mellitus is Wolfram Syndrome, which arises from mutations in wolframin gene found on chromosome 4. Optic nerve atrophy, diabetes insipidus, sensorineural deafness, psychiatric problems can accompany diabetes mellitus, so it can be also named as DIDMOAD syndrome. Hypergonadotrophic hypogonadism can be rarely observed in Wolfram syndrome. A case of novel homozygous mutation in the wolframin gene has been reported because of concomitant rare...

Introduction: The most common type of diabetes in childhood is type-1 diabetes. The group of diabetes called MODY (maturity-onset diabetes of the young) is rarer. Mutations that occur in glucokinase gene cause disruption in the perception of the resultant glucose level and, consequently, impaired insulin release, leading to the development of MODY-2. In this case, resulting hyperglycemia is usually at a mild, non-progressive level and does not require insulin therapy. For this...

Resistance to thyroid hormone (RTH) is a rare genetic disease caused by reduced tissue sensitivity to thyroid hormone. The hallmark of RTH is elevated serum levels of thyroid hormone with unsuppressed thyrotropin (TSH). The most common form of RTH results from minor defects in the ligand-binding domain of the TRb gene, resulting in impaired T3-induced transcriptional activity. This study aimed to characterize clinical and genetic features of THD suspected cases in our clinic. ...

Background: Intratubular Large Cell Hyalinizing Sertoli Cell Neoplasia (ITLCHSCN) resulting from Sertoli cells of the testis are mainly reported in young adults and these are rarely seen in childhood.Objective and hypotheses: In this case report, an eight-and-a-half-year old case presenting with complaint of bilateral gynecomastia since two years, showing no endocrine abnormality in laboratory during 2-years of follow-up, determined to have progression i...

Background: Polycystic ovary syndrome (PCOS) is a common endocrinological disorder of unclear etiopathogenesis characterized by hormonal and reproductive abnormalities which may coexist with metabolic disturbances.Objective and hypotheses: To investigate the role of endocrine disruptor bisphenol A (BPA) in etiopathogenesis of PCOS in adolescent girls. Additionally, we wished to investigate the relationship between BPA and metabolic parameters, insulin re...

Background: Polycystic ovary syndrome (PCOS), characterized by hyperandrojenemia, anovulatory periods and polycystic ovaries, is a disorder in which metabolic and reproductive abnormalities overlap. The etiopathogenesis is currently unclarified. Besides the evidence of genetic causes, environmental factors are considered to be involved in development of phenotype. Phthalates are widely used industrial chemicals and have several known untoward effects on human reproductive heal...

Background: Recent studies have shown a rising trend in pediatric obesity. However, studies dealing with the ultimate metabolic consequences of pediatric obesity and the means of accurately predicting these consequences are limited.Objective and hypotheses: To study the utility of WHtR as a marker of insulin resistance. To validate the presently used cutoffs (≧0.5) and validate its utility in populations studies.Method: 96 c...
