Background: Van Wyk–Grumbach syndrome (VWGS) is characterized by breast development, uterine bleeding and multi-cystic ovaries in the presence of long-lasting primary hypothyroidism.Objective and hypotheses: The pathophysiology of VWGS involves a complex mechanism, which is at least partly mediated by the direct action of TSH and FSH receptors.Method: We present a girl with Down syndrome having typical feature...

Background: Pancreas transcription factor-1 alpha (PTF1A), encoded by the PTF1A gene, is a beta helix loop(bHLH) protein which involved in the development of the pancreas and cerebellar neurogenesis. Although mutations of PTF1A cause permanent neonatal diabetes(PNDM), pancreas agenesis and cerebellar agenesis, PTF1A enhancer mutations reported causing PNDM and isolated pancreas agenesis. In the present study, we evaluate the phenotyp...

Background: Aldosterone synthase deficiency (ASD) caused by mutations in the CYP11B2 gene is characterized by isolated mineralocorticoid deficiency. Data is scarce regarding clinical and biochemical outcomes of the disease in the follow-up.Objective: Assessment of the growth and steroid profiles of patients with ASD at the time of diagnosis and after termination of treatment.Design an...

Autosomal dominant DICER1 mutations are among the causes of early-onset familial cancer. DICER1 mutation has been shown in pleuropulmonary blastomas as well as ovarian tumors, thyroid, parathyroid, pituitary, adrenocortical and testicular tumors. It is important to be aware of the risk for the development of other cancers in the follow-up of these cases.Cases: Case-1: Previously known to be healthy 8,5-year-old girl presented with compla...

Background and aim: C-peptide is an important indicator of endogenous insulin release. Our aim was to investigate the association of serum C-peptide levels with age, BMI and insulin doses in newly diagnosed type 1 diabetic (DM1) children.Metods: The patients with newly diagnosed DM1 were enrolled the study and classified as DM1A and DM1B. Clinical and laboratory findings of all the patients were recorded. Daily insulin doses, BMI and its z score were cal...

Introduction: In the pediatric age group, the incidence of the adrenocortical cancer (ACC) is 0.2%. The effective treatment is surgical resection. The only medical option is mitotane but it has negative effects on steroidogenesis. The difficulty in the management of mitotane therapy is discussed in this case.Case report: An 1110/12 years-old boy was referred with A 5 cm diameter solid-hypoecoic mass observed by sonography in the left surrenal ...

Background: Irisin is an adipomyokine secreted by many tissues. Because it has known relationships with the energy metabolism and exercise, its relationships with obesity and type 2 diabetes (T2D) are being focused on. Its relationship with type 1 diabetes (T1D) is unknown.Objective and hypotheses: In this study, the relationships between the serum irisin level and the metabolic control were investigated in adolescents with T1D.Met...

Background: The prevalence of childhood obesity is increasing all over the world and leading to an increase in obesity-related health problems such as adult obesity, cardiovascular diseases, type 2 diabetes and depression. There is no nationwide systematic study investigating obesity trends in Turkish children.Objective and hypotheses: The aim of this study is to determine the prevalence of overweight and obesity among school age children, to compare the...

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: Subclinical hypothyroidism (SH) is defined as an elevated serum concentration of TSH when serum free thyroxine (fT4) concentration is within its reference range. Impaired myocardial contractility in overt hypothyroidism and left ventricular (LV) diastolic dysfunction in adults with SH as well as beneficial effects of thyroid hormone replacement on systolic and diastolic functions in adults with SH has been documented, however the presence of similar alte...
