Introduction: Prolactin is a multifunctional pituitary hormone. The effect of prolactin on platelet activation is not well understood. Prolactinomas are the most common type of pituitary adenomas, and they are medically responsive to dopamine agonists. Mean platelet volume (MPV) is a marker of platelet function and activation. The aim of this study was to evaluate MPV values before and 6 months of cabergoline treatment when normoprolactinemia was achieved.<p class="abstext...

Introduction: 80–90% of insulinomas are smaller than 2 cm, equally located in the head, body and tail of pancreas. Computer tomography (CT) is 75%, magnetic resonance imaging (MRI) is 55–90%, endoscopic ultrasonography (EUS) is 85–95% and selective arterial calcium stimulation test (SACST) is 95–100% sensitive in the diagnosis of insulinomas. Here, we presented two cases of insulinoma which could not be located by conventional methods and evaluated with SAC...

Introduction: Thyroid tumors of uncertain malignant potential (TT-UMP) has been accepted as a subgroup of follicular-patterned thyroid tumors for which benignancy or malignancy cannot be assessed exactly. We aimed to evaluate demographic characteristics, ultrasound (US) findings, and cytological results of patients with TT-UMP and compare these findings with the classical variant of papillary thyroid carcinoma (CV-PTC) and non-encapsulated follicular variant of PTC (NEFV-PTC) ...

Introduction: Hyalinizing trabecular tumor is a very rare neoplasm of thyroid and can be misinterpreted as papillary or medullary cancer in fine needle aspiration biopsy (FNAB).Case report: Multinodular goiter was detected in a 65 years old woman using metformin and L-thyroxine for impaired blood glucose and Hashimoto thyroiditis, respectively. FNAB was performed in two nodules and reported as suspicious for malignancy and benign. She underwent total thy...

Introduction: Increasing evidence is available for the role of prolactin in the development of various cancers. The purpose of this study is to evaluate the frequency of thyroid cancer in patients with prolactinoma followed up at a single site.Materials and methods: Medical records of 182 patients, diagnosed with prolactinoma, were reviewed retrospectively. Out of these patients, 114 patients (103 female patients, 11 male patients, mean age 35±10.4)...

Riedel thyroiditis is a rare chronic inflammatory disease of the thyroid. It is characterized by replacement of normal parenchyma with dense fibrotic tissue. Peripheral tissues might also be affected and this may cause airway obstruction, dysphagia, recurrent laryngeal nerve palsy and hypoparathyroidism. We report a patient with toxic adenoma previously treated with radioactive iodine and histopathologically confirmed Riedel thyroiditis.Case: A 61 years ...

Introduction: Nowadays, ultrasonography (USG) is being used very commonly and indispensably for diagnosing thyroid diseases. Heterogeneous appearance of thyroid parenchyma is associated with positivity for thyroid autoantibody and hypofunctioning of thyroid gland. On the other hand, it is not determined whether thyroid parenchyma appearing totally of normal ecogenity on USG is related to presence normal thyroid function tests or otherwise. The objective of our study was evalua...

Introduction: Acromegaly is an acquired disorder related to excessive production of growth hormone (GH) and insulin-like growth factor-1 (IGF-1). It is characterized by progressive somatic disfigurement and systemic manifestations. Empty sella (ES) is an anatomical condition comprising sella turcica that is partially or completely filled with cerebrospinal fluid mainly due to intrasellar herniation of subarachnoid space. Primary ES may be associated with endocrine dysfunction ...

Aim: In this study, we aimed to evaluate ABO blood groups and Rh factor in patients with thyroid cancer. We also assessed whether the ABO/Rh factor had any effect on prognosis, agressive features and advanced stage of thyroid malignancies.Methods: Medical records of patients who underwent thyroidectomy between December 2006 and September 2014 were evaluated retrospectively. Demographical and clinical features, cytological results (according to Bethesda c...

ObjectivesAdherence to treatment is one of the most important parameters that affect the success of the treatment in hypothyroidism. We aimed to evaluate the use and adherence to treatment and determine the factors that are related to adherence in patients on levothyroxine therapy.Materials and MethodsPatients older than 18 years old and using levothyroxine for hypothyroidism were recruited. Demographical, so...
