Yildiz Melek , Bas Firdevs , Karaman Birsen , Poyrazoglu Sukran , Basaran Seher , Darendeliler Feyza ,

Background: In Silver-Russell Syndrome (SRS), it is known that puberty starts early, frequency of premature adrenarche increases and adrenarche progresses aggressively. However, data regarding gonadal functions and testicular development in males during pubertal period is still insufficient.Methods: Twenty-four cases (9F, 15M) who were followed-up with diagnosis of SRS between 1990-2020 were included in the study. The di...

Karaman Volkan , Karakilic-Ozturan Esin , Bas Firdevs , Poyrazoglu Sukran , Basaran Seher , Darendeliler Feyza , Oya Uyguner Zehra ,

Background: Approximately one-third of the central precocious puberty (CPP) cases have familial transitions. Although more than 30 genes related to puberty have been reported to date, only a few (KISS1, KISS1R, MKRN3, DLK1 and PROKR2) were associated with CPP. This study aims to reveal the associated sequence variants of MKRN3 and DLK1 genes in cases with familial CPP and their etiology.Method:...

Karakilic Ozturan Esin , Bas Firdevs , Yavas Abali Zehra , Karaman Volkan , Poyrazoğlu Sukran , Oya Uyguner Zehra , Darendeliler Feyza

Background: Melanocortin receptor 2 (MC2R) is expressed in the adrenal cortex and has a major role in the control of the hypothalamic-pituitary-adrenal axis. It is reported that the ACTH receptor MC4R has an impact on premature adrenarche. The melanocortin signaling system is reported to have leptin mediated effect on the regulation of GnRH neuron activity and has an important role in the onset of puberty and fertility.Objective:...

Gencay Ali Genco , Darendeliler Feyza , Nisli Kemal , Karaca Serra , Kardelen Asli Derya , Poyrazoglu Sükran , Bas Firdevs

Background: The most common reason for the increased mortality and morbidity in TS, which results from partial or complete deficiency of an X chromosome in a female, is acquired cardiovascular disease, which is the result of endothelial dysfunction that causes atherosclerosis. Endocan, an inflamatory marker, has been found elevated in several diseases with endothelial dysfunction (ED). There is no study of endocan levels in TS.Ob...

Background: Neonatal diabetes mellitus (NDM) is a form monogenic diabetes diagnosed under 6 month of age.Objective and hypotheses: To describe the clinical and molecular features of NDM patients in a Turkish cohort.Method: Fifteen patients (13M, 2F) with diabetes onset before 6 months of age were included in the study. Clinical and molecular data were evaluated retrospectively.Results: Mean age at diagnosis w...

Associations of Vascular Biomarkers and the Somatotrophic Axis with Carotid Ultrasound and Echocardiography Findings in Relation to Turner Arteriopathy

Ucar Ahmet , Oz Fahrettin , Bas Firdevs , Oflaz Huseyin , Nisli Kemal , Tugrul Melike , Darendeliler Feyza , Saka Nurcin , Poyrazoglu Sukran , Bundak Ruveyde

Background: Turner syndrome (TS) is associated with increased arterial stiffness. To date, factors associated with the ontogeny of Turner arteriopathy remain unclear.Objective and hypotheses: To assess the associations of vascular biomarkers and the somatotrophic axis with arterial stiffness indices, and left heart size, in normotensive ‘dipper’ TS.Method: Sixty-one patients with uncomplicated normotentensive &#1...

Evaluation of Sitting Height/Height SDS in Patients with Turner Syndrome

Genens Mikayir , Kaya Gamze , Ulak Ceren Melis , Poyrazoglu Sukran , Bas Firdevs , Bundak Ruveyde , Saka Nurcin , Darendeliler Feyza

Background: Short stature and gonadal dysgenesis are the main characteristics in Turner syndrome (TS). There are conflicting reports about the body proportions in TS. Some studies described a proportionate short stature, whereas others reported disproportionately short legs. It is known that body proportions are genetically controlled and are different in different populations or ethnic groups.Objective and hypotheses: To evaluate body proportions assess...

Objective: To evaluate metabolic syndrome parameters in children with premature adrenarche (PA) during presentation in prepuberty and afterwards in puberty.Methods: 54 (48 femals, six males) patients (mean age 12.5±2.4 years) diagnosed with PA and followed until puberty were included in our study; as the control group 28(22 females, six males) (age, sex, puberty matched) healthy children (mean age 13.5±2.2 years) were taken. CAH was ruled out i...

Background: The prevelance of pediatric obesity is increasing in childhood. Nonalcoholic fatty liver disease (NAFLD) is frequently associated with obesity, insulin resistance (IR), diabetes, and hypertriglyceridemia. Gut microbiota was suggested to play a role in both etiology of NAFLD and also progression to steatohepatitis. Feacal calprotectin (FCP) is a noninvasive marker of intestinal inflammation.Objective and hypotheses: To evaluate FCP and its ass...
