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...

Metastatic infiltration of the adrenal glands is a common finding of malignancies, but few case reports showed primary adrenal insufficiency being the presenting manifestation of underlying malignant tumors. Here, we report a case of adrenal insufficiency secondary to metastases from lung adenocarcinoma.A 69-year-old man was admitted to emergency department with weakness, altered mental status, hypotension, fever and weight loss. He had 100 pack-year his...

Introduction: Diabetic patients have an increased risk of developing dementia and cognitive impairments. DM related factors such as macrovascular and microvascular complications, glucose toxicity, hyperinsulinemia have been suggested to be involved cognitive impairment even in prediabetic stage. Our aim is to establish the relationship between insulin resistance and cognitive impairment and the effect of poorly controlled diabetes on cognitive impairment.<p class="abstext"...

Background: Fine needle aspiration biopsy (FNAB) has proven to be the most valuable diagnostic procedure for preoperative discrimination of benign and malignant nodules. Bethesda System for Reporting Thyroid Cytopathology (TBSRTC) has standardized reporting and cytomorphological criteria in aspiration smears. In this study, we aimed to determine malignancy rates in nodules with different cytology results and diagnostic value of TBSRTC for variants of papillary thyroid carcinom...

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: The increased rate of thyroid malignancy as well as incidental and subcentimeter thyroid nodules have been attributed to increasing use of high-resolution US which can detect the non-palpabl or subcentimeter (maximum diameter ≤1 cm) thyroid nodules. We aimed to evaluate the sonographic features of the tyroid nodules between ≤1 cm and > 1 cm according the histopathology results and to determine the ultrasonographical predictive factors for malignan...

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...

Introduction: Primary hyperparathyroidism (PHP) is a highly prevalent disease, which is treated most effectively by surgery. Postoperative hypocalcaemia, a morbidity of surgical treatment of parathyroidism, can prolong the hospital stay. The aim of this study was to identify the factors predictive of hypocalcaemia and hungry bone syndrome (HBS) in patients who undergo parathyroidectomy due to PHP.Materials and methods: Preoperatively and on days 1 and 4,...

Introduction: Ocular changes are common in various endocrine disorders. However, there are only few studies reporting ocular changes in patients with primary hyperparathyroidism (PHPT). Here, we examined central corneal thickness (CCT) and retinal thickness (RT), intraocular pressure (IOP) and their relationships with serum intact parathyroid hormone (iPTH), calcium (Ca), and phosphorus levels in PHPT patients.Methods: Thirty-seven patients with PHPT wer...
