Introduction: In this study, we aimed to evaluate impact of multifocality, tumor number and total tumor diameter on clinicopathological features of PTC.Methods: Medical records of 912 patients who underwent thyroidectomy and diagnosed with PTC were reviewed retrospectively. Patients were grouped into 4 according to number of tumoral foci; N1 (1 focus), N2 (2 foci), N3 (3 foci) and N4 (≥ 4 foci). The diameter of the largest tumor was considered as t...

Introduction: In this study, we aimed to evaluate the usefulness of ratio of primary tumor diameter to total tumor diameter as a new parameter for the differentiation of agressive and favorable papillary thyroid microcarcinomas (PTMC).Methods: The diameter of the largest tumor focus was taken as the primary tumour diameter (PTD). For multifocal tumors, total tumor diameter (TTD) was calculated as the sum of the maximal diameter of each lesion. A ratio wa...

Aim: The intima–media thickness (IMT) measurement of the common carotid artery is recognised as an important marker of systemic atherosclerosis. It may be useful in predicting the cardiovascular events, since it is related to the severity of coronary artery disease. The aims of this study were to analyse whether correlations exist between the IMT of the common carotid artery and the main clinical and biochemical parameters in patients with primary hyperparathyroidism (PHP...

Introduction: We report stage IV B cell lymphoma in a patient presenting with adrenal failure and an intraabdominal mass which imaging techniques were suggestive for paraganglioma.Case report: A 71-years-old woman admitted to our emergency clinic with severe fatigue and stupor. She was diagnosed to have primary adrenal failure since serum ACTH was 229 pg/ml and cortisol response to 250 μg co-syntropin was 6.17 μg/dl. In abdominal MRI, bilateral...

Introduction: Primary hyperparathyroidism (PHPT) is a prevalent endocrinologic disease and the most common cause of hypercalcemia. PHPT usually affects the elderly. PHPT younger than 40 years of age is less frequent. In young patients especially for ones younger than 30 years of age, screening for familial syndromes such as MEN 1 and MEN 2A is recommended. However, in most of the cases genetic tests are negative and evidence for other endocrine components are absent. Herein th...

Background: Fine needle aspiration biopsy (FNAB) and Bethesda System for Reporting Thyroid Cytopathology (TBSRTC) have proven to be the most valuable diagnostic procedure for preoperative discrimination of benign and malignant thyroid nodules. Thyroid surgery may cause regional scarring and some degree of fibrotic process which may result in problems when collecting FNAB samples and evaluating the cellular abnormalities. In this study, we aimed to determine whether the Bethesd...

Introduction: In this study, we aimed to compare GH values obtained in oral glucose tolerance test (OGTT) and intravenous glucose tolerance test (IVGTT) in healthy individuals.Material and methods: Data of 18 healthy volunteers were analysed (10 male and 8 female). Firstly all subjects were evaluated with 75 g oral glucose tolerance test. In another day, intravenous glucose tolerance test was performed. Serum glucose, insulin and GH levels obtained durin...

Introduction: Follicular variant papillary thyroid carcinoma (FVPTC) is the most common variant of papillary thyroid carcinoma (PTC) after classical PTC (CPTC). In this study, we aimed to compare functional status, ultrasonographical features, cytological results and histopathological characteristics of patients with CPTC and FVPTC.Methods: Patients diagnosed with CPTC and FVPTC in our clinic were reviewed retrospectively. Data of preoperative thyroid fu...

Introduction: Aortic elastic properties and aortic stiffness are important determinants of increased cardiovascular morbidity and mortality in different diseases. We aimed to investigate the aortic function and to evaluate the relationship between aortic stiffness and systolic and diastolic functions of the left ventricle in patients with Cushing’s disease (CD).Material and method: Fourteen women and one man with newly diagnosed CD, and 17 control c...

Aim: We aimed to investigate the relation between preoperative serum thyrotrophin (TSH) and clinicopathological features in patients with papillary thyroid carcinoma (PTC) and microcarcinoma (PTMC).Methods: Patients who underwent thyroidectomy and diagnosed to have benign nodular disease or PTC/PTMC in our clinic were evaluated retrospectively. Patients with a previous history of thyroid surgery, patients using antithyroid medications or thyroid hormone ...
