Introduction: Although medullary thyroid cancer (MTC) constitutes 2–4% of all thyroid cancers, it is associated with higher mortality compared to differentiated thyroid carcinomas. Here we present long term clinical results of medullary carcinoma patients’ follow-up in our center.Methods and results: MTC was detected in 27 (3.73%) patients of 850 thyroid cancer cases who were followed-up between 2004 and 2020 at the Marmara University School ...

Objective: Hyperprolactinemia has been reported to be associated with endothelial dysfunction, abnormalities of carbohydrate metabolism and insulin sensitivity. The aim of this study was to evaluate carbohydrate metabolism and endothelial function of our patients in outpatient clinics.Material and methods: In this cross-sectional study, currently or previously treated 87 hyperprolactinemic patients with PRL-secreting adenoma (fifty four with microadenoma...

Background and aim: Low testosterone levels are known to be associated with unfavorable body composition and testosterone replacement is known to be associated with increased muscle mass and muscle strength. The aim of this cross-sectionalstudy is to evaluate the grip strength, appendicular muscle mass and physical performance and bone mineral densities of hypogonad male patients.Method: 75 hypogonad and 45 healthy control subjects were included in this ...

Introduction: Acromegalic osteopathy is an emerging complication characterized by high risk for vertebral fractures (VFS), whereas bone mineral density (BMD) may not be useful to predict the risk. Recent studies have reported that increased advenced glycation end products (AGEs) are associated with bone fragility. We aimed to evaluate the relationship between AGEs and VFs in patients with acromegaly.Study design: Cross-sectionalPat...

Introduction: Various rates were reported regarding diabetes remission and improvement in hyperglycemia in many studies from different populations. Determinants of diabetes remission have not been definitively established so far. In this study, we aimed to evaluate the long-term glycemic status after bariatric surgery in diabetic obese patients followed by Marmara University Endocrinology Outpatient Clinic.Method: The retrospective study included 233 typ...

ApoB plays a central role in lipoprotein metabolism through regulation of total cholesterol and LDL-cholesterol (LDL-C) concentrations in plasma. Two restriction fragment length polymorphisms (ECoRI and XbaI) represent single base alterations in the coding region of ApoB gene. ECoRI polymorphic region of ApoB gene is due to on an amino acid change (Glu→Lys). The XbaI polymorphic region of ApoB gene results from a substitution of (A→T) in the threonine codon and doe...

Hypoparathyroidism is a rare endocrine disorder whose epidemiologic characteristics regarding the cause, clinical course, acute and chronic complications have not been well defined. There is also a substantial geographic variability regarding those parameters, and country-specific local data is scarce.This study was conducted to assess the baseline characteristics, including the demographics, etiologic distribution, disease severity, medications use...

Background: Treatment of vitamin D deficiency orinappropriate vitamin D supplementation may cause side effects associated with hypercalcemia. We observed a tendency to use very high single dose cholecalciferol for treatment of vitamin D deficiency.Aim: The primary aim of this study was to examine the clinical characteristics of patientswith very high serum 25OHD levels of vitamin D toxicity in Turkey.Materials and methods: An invit...
