Cayir Atilla , Akyigit Ali , Gullu Ufuk Utku , Kahveci Hasan , Yildiz Duran , Kurnaz Erdal , Vuralli Dogus , Kaya Abdulkadir , Demirbilek Huseyin

Objective: Vitamin deficient (VDD) rickets can manifest with skeletal (hypocalcemia, hypophosphatemia, elevated serum alkaline phosphatase and defective bone mineralization) and extra-skeletal findings. There are certain number of case reports and limited number of small scale studies reporting dilated cardiomyopathy due to VDD rickets.The aim of the present study is to evaluate the clinical, biochemical and echocardiographic features of...

A Novel Approach for the Evaluation of Hypothalamic-Pituitary Region in Patients with Growth Hormone Deficiency: Pons Ratio

Demiral Meliha , Karaca Mehmet Salih , Unal Edip , Baysal Birsen , Baran Riza Taner , Demirbilek Huseyin , Ozbek Mehmet Nuri

Objective: In patients with growth hormone deficiency (GHD), even in those with no major organic lesion, anterior pituitary height (APH) is reported decreased. Limitations in the evaluation of APH and changes according to pubertal status make its validity questionable. Recently, in a small scale study, pons ratio (PR) has been suggested as a more sensitive marker for evaluation of pituitary gland in GHD patients. The study aims to evaluate the validity of PR a...

Presenting Features, Clinical Characteristics and Follow up of Familial Isolated Glucocorticoid Deficiency (FGD) due to Mutations in MC2R and MRAP Genes

Ozbek Mehmet Nuri , Karaşin Nezehat Doğan , Demirbilek Huseyin , Demiral Meliha , Baran Rıza Taner , Guran Tulay

Objectives: Familial glucocorticoid deficiency (FGD) is a rare autosomal recessive disorder characterized with isolated glucocorticoid deficiency. Melanocortin receptor 2 (MC2R) mediates the functions of adrenocorticotropic hormone (ACTH) in the adrenal cortex. MC2R accessory protein (MRAP), a transmembrane protein, involves in the trafficking of MC2R to the cell surface. Mutations in MC2R and MRAP genes cause FGD type 1 and 2. Herein, we ev...

Evaluation of Intraocular Pressure and Retinal Nerve Fiber Layer, Retinal Ganglion Cell, Central Macular Thickness and Choroidal Thickness Using Optical Coherence Tomography in Obese Children and Healthy Controls

Taner Baran Rıza , Baran Serpil , Fusun Toraman Naciye , Bilgilisoy Filiz Meral , Filiz Serkan , Demirbilek Huseyin

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...

Systemic Pseudohypoaldosteronism Type 1 Due to 3 Novel Mutations in SCNN1A and SCNN1B Genes; Report of 3 Cases

Cayir Atilla , Demirelli Yasar , Yildiz Duran , Kahveci Hasan , Yarali Oguzhan , Karaoglan Dogus Vuralli , Kurnaz Erdal , Demirbilek Huseyin

Objective: The systemic form pseudohypoaldosteronism type 1 (PHA1) is an autosomal recessive disorder characterized with defective sodium transport in many organ systems including kidney, lungs, colon, sweat glands and salivary glands. Homozygous or compound heterozygous loss-of-function mutations in the genes encoding amiloride sensitive epithelial sodium channel (ENaC) account for genetic causes of systemic PHA1.Case 1: Male patient presented with vomi...

A Syndrome of Permanent Neonatal Diabetes Mellitus and Neurological Abnormalities due to a Novel Homozygous Missense c.449T>A (p.I150N) Mutation in NEUROD1 Gene

Hatipoglu Nihal , Demirbilek Huseyin , Gul Ulku , Tatli Zeynep Uzan , Flanagan Sarah , Ellard Sian , De Franco Elisa , Kurtoglu Selim

Neonatal diabetes mellitus (NDM) is a rare form of monogenic diabetes presenting in the first 6 months of life. NEUROD1 is a transcriptional factor involved in the development of endocrine pancreas. A few patients with maturity onset diabetes of the young (MODY) due to heterozygous NEUROD1 mutations and only two cases with permanent NDM (PNDM) associated to neurological disorders and cerebellar hypoplasia due to homozygous mutations in the NEUROD1 gene have been reported.<...

Background: Euthyroid sick syndrome (ESS), also known as non-thyroidal illness or low T3 syndrome, is defined as low T3, low/normal T4 and inability of rise in TSH due to extrathyroidal diseases. Any condition resulting stress such as infectious diseases, sepsis, metabolic disorders and severe malnutrition can associate to ESS. Patients presented with type 1 diabetes mellitus (T1DM) are usually being screened for other autoimmune diseases inclu...
