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: 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...

Introduction: Several studies have shown that prediabetic patients had increased concentrations of inflammatory markers and this association is independent of underlying obesity. Netrophil to lymphocyte ratio (NLR) is considered as a new inflammatory marker and has been studied extensively in a variety of clinical conditions especially in solid tumours and cardiovascular diseases. Studies evaluating the subclinical inflammation in prediabetes revealed positive association of s...

Introduction: Reoperative surgery for thyroid disease is rare. It is sometimes indicated for nodular recurrence after partial surgery for initially benign thyroid disease or for a completion total thyroidectomy when a final diagnosis of thyroid cancer is confirmed on a permanent section of a partially removed thyroid gland. We aimed to investigate the demographic features and reoperation indications in patients with reoperative thyroidectomy.Methods: Thi...

Introduction: Fine needle aspiration (FNA) is the first-line diagnostic test for evaluating thyroid nodules. This test can effectively distinguish between neoplastic and non neoplastic nodules. The Bethesda System suggest that thyroid nodules with non diagnostic (ND), atypia/follicular lesions of undetermined significance (A/FLUS) aspiration should undergo repeat sampling. We aimed to investigate the clinical validity of repeated FNA in the management of patients with thyroid ...

Introduction: Radioactive iodine (RAI) therapy is widely used in the treatment of hyperthyroidism especially in patients with Graves’ disease (GD), toxic multinodular goitre (TMNG), and toxic adenoma. RAI may lead to worsening of the autoimmunity with the elevation of TSH-receptor antibody (TRAB). In this study, we aimed to compare the effects of surgery or RAI treatment on TRAB.Methods: Hyperthyroid patients were divided into three groups; patients...

Objective: Serum total sialic acid(SA) concentration is assessed as an up to date risk indicator of atherosclerosis and cardiovascular diseases.Methods: It was aimed to investigate about how SA levels are effected in overt or subclinical hypothyroidism (SH) and how it’s associated with other atherosclerosis risk factors because there is no study about these topics, though SA is intensively studied in recent years.Patients: Six...

Objective: Primary hyperparathyroidism (PHPT) is a clinical condition characterized by hypercalcemia-specific symptoms and signs caused by excessive secretion of parathormone. After the evaluation of blood calcium measurements within routine tests, the frequency of hyperparathyroidism increased and there is a marked decrease in the frequency of classical symptoms and signs. Recently, most PHPT cases are detected in the asymptomatic period, and which of these asymptomatic patie...

Atypical tumors were identified in 15% of pituitary adenomas, and they tended to be aggressive, invasive macroadenomas. WHO classification of atypical pituitary adenomas include; Ki-67 proliferative index >3%, excessive p53 immunoreactivity, and ≥ 2 mitotic figures per 10 high-powered fields. Pituitary carcinomas are extremely rare tumors with cerebrospinal or extracranial metastasis.Case: A 31 years old man with symptoms of stuffy nose and sno...

Introduction: Fine needle aspiration cytology (FNAC) has been widely accepted the most accurate, safe and cost-effective method for evaluation of the thyroid nodules. The most challenging category in the FNAC is atypia of undetermined significance (AUS) and follicular lesion of undetermined significance (FLUS). Bethesda System (BS) recommends repeat FNAC in that category due to their low risk of malignancy. In our study, we aimed to investigate the malignancy rate of thyroid n...
