Introduction: Upper gastrointestinal (UGI) symptoms are frequently encountered in patients with primary hyperparathyroidism (PHPT). Some of these symptoms may improve after PHPT treatment, while hypercalcemic state may also cause permanent effects. We aimed to evaluate UGI symptoms, UGI endoscopic and pathologic features and determine the relationship between these features with serum chromogranin A (CgA) and gastrin in PHPT patients.Methods: Seventy-one...

Introduction: Although, familial medullary thyroid cancer is a known condition, familial papillary thyroid cancer (PTC) is a rare and less well described clinical entity. While some studies suggest more aggressive features in familial PTC, some do not support these findings. We aimed to compare ultrasonographical, cytopathological and histopathological results of patients with familial and sporadic PTC.Methods: Data of 194 patients diagnosed with PTC his...

Introduction: Ectopic adrenocorticotrophic hormone (ACTH) syndrome is associated with variable tumor groups most commonly originating from neuroendocrine cells. Here, we reported a patient considered to have nonconvulsive status epilepticus initially due to neurological symptoms and diagnosed as neuroendocrine tumor with ectopic ACTH syndrome.Case: A 85 years old woman with regulated hypertension admitted with partial loss of conciousness. She had cachec...

Introduction: Hepatic dysfunction in hyperthyroidism may occur due to high thyroid hormones, medications or associated autoimmune liver disease. Autoimmune hepatitis or primary biliary cirrhosis (PBC) has rarely been reported in Graves’ disease. We report a patient presenting with pruritus and diagnosed as accompanying PBC and Graves’ disease.Case: A 50 years old female patient applied with progressive pruritus for at least 4 months. Laboratory...

Aim: In this study we aimed to evaluate the oxidative stress via evaluating changes in dynamic thiol-disulphide status in euthyroid patients with Hashimoto’s thyroiditis (HT).Methods: Fifty euthyroid patients with HT and 50 healthy individuals were enrolled in this study. Thyroid function tests (free triiodothyronine (fT3), free thyroxine (fT4), thyrotropin (TSH)), acute phase reactants (C-reactive protein (CRP), high sensitive CRP (hs-CRP)) and thi...

Aim: Atypia/follicular lesion of undetermined significance(AUS/FLUS) is a category of thyroid cytology with features that are neither definitely benign or malignant. We aimed to determine whether specific cytologic or architectural features are associated with malignancy in AUS/FLUS category of Bethesda system according to subgroups.Methods: The specimens of patients who underwent surgery with preoperative thyroid fine neeedle aspiration (FNA) biopsies o...

Introduction: Although malignancy rate is low in thyroid nodules with nondiagnostic (ND) cytology, it is reported as higher in persistent ND nodules. We aimed to determine the role of ultrasonography (US) features and Thyroid Imaging Reporting and Data System (TIRADS) in the prediction of malignancy in patients with persistent ND cytology.Methods: 246 patients who underwent thyroidectomy with an indication of at least two ND cytologies were included in t...

Introduction: Recently, it has been suggested that thyrotropin (TSH) concentration can be used as a marker for prediction of thyroid malignancy. However, the association between the cytology results and TSH levels is not clear. In this study, we aimed to investigate the relationship between TSH levels and Bethesda categories and determine the role of TSH levels in prediction of malignancy in patients with different Bethesda categories.Methods: The data o...

Introduction: Incidental thyroid carcinoma (ITC) in patients operated on for a benign disease is frequent. ITC characteristics in patients operated for malign disease, but not sampled by fine needle aspiration (FNA) or seen in ultrasonography, is unknown. We aimed to compare ITC with nonincidental ITC (NITC) in this study.Material and method: Retrospective analyses of 918 individual patients who were operated for benign and malign thyroid disease in our ...

Background: We aimed to evaluate malignancy rate in thyroid nodules ≥4 cm and determine false negativity of fine needle aspiration biopsy (FNAB) in these nodules.Methods: Patients who underwent thyroidectomy between January 2007 and December 2014 in our institution were reviewed. Demographical and clinical data and preoperative ultrasonography (US) findings were obtained from the medical records. The nodules in these patients were grouped as &#8805...
