Background: Androgens play a pivotal role in non-reproductive tissues, such as the kidney, heart, and liver, as well as the pancreas. Since the androgen receptor is expressed in pancreas and liver cells, this raises the possibility that excess testosterone results in insulin hypersecretion, and in fetuin-A, a protein produced in the liver. However, whether fetuin-A and insulin levels are affected by androgens in classic congenital adrenal hyperplasia (CAH) due...

Background: CD59 is a complement regulatory protein which inhibits membrane attack complex protecting self-cells from complement-mediated damage. Recent evidence suggests CD59 may suppress T cell activation via a complement-independent mechanism. Other than an immune regulator, CD59 is shown to regulate glucose stimulated insulin secretion. Herein we report a patient with inherited CD59 deficiency who developed type 1 diabetes.Case: 11 year-old girl was ...

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: X-linked lissencephaly with ambiguous genitalia (XLAG) syndrome which is a clinical spectrum of ARX mutations is presented with severe growth deficiency, abnormal genitalia and resistant seizures in neonatal period. We present a XLAG case which was formed due to a new ARX mutation and has an appearance of a huge interhemispheric cyst different from classic neuroradiological imagings.Case: The case which was diagnosed with prenatal hydrocephal...

Background: Phthalates are industrial chemicals extensively used as plasticizers in a variety of commercial products. Di-(2-ethylhexyl) phthalate (DEHP) is one of the most frequently used phthalates. DEHP is readily metabolized to mono-(2-ethylhexyl) phthalate (MEHP), which is more toxic than its parent compound. There are some animal and in vitro studies suggesting that phthalates can disrupt hypothalamus-pituitary-thyroid axis.Objective and hy...

Objective: Fetuin-A has many different functions due to its ability to bind to different toll-like receptors in different tissues. Working in different groups will contribute to our understanding of the pathophysiology of Fetuin-A. In this study, we aimed to evaluate Fetuin-A levels in obese adolescents and the relationship between Fetuin-A and anthropometric data, insulin levels and high sensitivity CRP(HSCRP). Material and Meth...

Objective: Obesity and its complications affecting many organ systems have been documented. Nevertheless, study conducted on the ophthalmological effects of obesity are scarce. The aim of the present study was to evaluate the changes in the ophthalmological parameters in obese children in comparison to their healthy counterparts.Material and methods: Study included 61 obese and 35 age-sex matched controls. Obesity was defined as body mass index- standard...

Background: C1q/tumor necrosis factor-related proteins (CTRPs) are the recently recognized members of the adipokine family, secreted from adipose tissue. Some types of CTRPs, including CTRP-13, play an important role in energy metabolism in humans. Also, CTRP-13 was found as an anorexigenic factor in experimental studies.Objective: We aimed to investigate serum CTRP-13 levels in obese and healthy children, as well as the...

Objective: Congenital Hyperinsulinism(CHI) is a clinically, genetically, and histologically heterogeneous disease. Turkey is a county with highly prevalent cases of severe CHI due to the high rate of consanguinity and recessively inherited KATP gene mutations. We herein evaluated the clinical characteristics, molecular genetic analysis, and follow-up of a large nationwide cohort of CHI from Turkey.Patients and method: Th...

Introduction: In 1950s - 1960s, the thalidomide disaster resulted in congenital malformations in more than 10,000 children. Derivative of thalidomide interferes with early embryonic transcriptional regulation due to selective degradation of SALL4 protein and thus, thalidomide embryopathy phenocopies pathogenic variants of the SALL4 gene. Their phenotypes range from phocomelia, reduced radial ray, to defects of the heart, kidneys, eye, and cerebral mid...
