The Association Between Subcategorization, Cytomorphological Features and Ultrasonographic Characteristics With Surgical Outcomes of Atypia of Undetermined Significance Thyroid Nodules.

Introduction We aimed to investigate malignancy rates in atypia of undetermined significance (AUS) subcategories and their association with cytomorphologic and ultrasonographic features. Methods A total of 201 thyroid nodules with AUS cytology that underwent surgical resection were analy-zed, including 169 AUS-Nuclear (AUS-N) and 32 AUS-Other (AUS-O) nodules. Cytomorphological and ultrasonographic features, along with the American College of Radiology Thyroid Imaging Reporting and Data System (ACR-TIRADS) and the European Thyroid Imaging Reporting and Data System (EU-TIRADS) classifications, were analyzed to assess the association between malignancy and AUS subcategories.

The Role of Blood Cell-Derived Parameters in the Differential Diagnosis of Subacute Thyroiditis and Graves' Disease and Long-Term Outcomes in Subacute Thyroiditis.

Purpose: To assess the utility of blood cell-derived parameters in differentiating subacute thyroiditis (SAT) from Graves' disease (GD) and their association with recurrence and the development of permanent hypothyroidism in the patients with SAT.

Methods: The study involved 414 patients with SAT, 415 patients with GD, and 92 healthy controls. Pre-treatment hematological parameters were retrospectively compared, especially in cases where differentiation is challenging, including painless SAT, acute phase reactants negative SAT, and TSI, TRAB (Thyroid Stimulating Immunoglobulin, TSH-receptor-antibodies) negative GD.

Seasonal Changes in Thyrotropin and Thyroid Hormones in Women of Reproductive Age.

Background: Thyroid hormones are essential for the proper functioning of the female reproductive system. Seasonal changes in thyroid hormones in women of reproductive age are not fully understood. we aimed to investigate seasonal changes in thyrotrophin and thyroid hormones in women of reproductive age.

Investigation of pre-operative demographic, biochemical, sonographic and cytopathological findings in low-risk thyroid neoplasms.

Objective: The present article analyses pre-operative demographic, biochemical, sonographic and histopathological characteristics of low-risk thyroid neoplasms (LRTNs), with a focus on four subgroups, "well-differentiated carcinoma-not otherwise specified" (WDC-NOS), "non-invasive follicular thyroid neoplasm with papillary like nuclear features" (NIFTP), "well-differentiated tumours of uncertain malignant potential" (WDT-UMP) and "follicular tumour of uncertain malignant potential" (FT-UMP).

Methods: The study retrospectively analyzed the histopathology of 2453 malignant thyroids and the final analyses included 99 cases diagnosed with LRTNs. The demographic and clinical features, pre-operative thyroid function, ultrasonography results, cytopathology results, histopathology results and prognostic classifications were assessed.

Effect of Ramadan Fasting on Thyroid Hormone Levels in Patients on Levothyroxine Treatment.

Objective: To evaluate the changes in thyroid functions in Ramadan, and compare late evening and pre-seheri use of levothyroxine in patients with hypothyroidism.

Study Design: Cross-sectional study.

Place And Duration Of Study: Department of Endocrinology, Ankara Ataturk Education and Research Hospital and Ankara Yildirim Beyazit University, Turkey, from May to June 2018.
