Introduction: Thyroid nodules can be detected by ultrasound (US) in 20–30% of unselected populations. Various non-surgical techniques such as laser and radiofrequency ablation have been developed to reduce thyroid nodule size. High-intensity focused ultrasound (HIFU) ablation is a new, non-invasive method that has been shown recently. The aim of our study was to assess the long-term efficacy and safety of US-guided HIFU treatment of benign solid thyroid nodules.<p cla...

Background: There is growing evidence supporting TNF-related apoptosis-inducing ligand (TRAIL) involvement in weight and body composition regulation, which are classically influenced by thyroid hormones. This study aimed at investigating the relationship between thyroid hormones and TRAIL.Methods: Circulating TRAIL was measured in 40 controls, 40 hyperthyroid, and 25 hypothyroid patients before and after their respective treatments. In the same patients ...

Introduction: The Bethesda System for Reporting Thyroid Cytopathology is the standard for interpreting fine-needle aspiration (FNA) and created a new diagnostic category (III): ‘atypia of undetermined significance/follicular lesion of undetermined significance’ (AUS/FLUS). The risk of malignancy for this category has been ascribed of 5–15% but the real malignancy rate remains unclear and plays a key role to define appropriate management.Ob...

Introduction: American Thyroid Association recommends that benign thyroid nodules should be revaluated 6–18 months after initial FNA and in case of stability the follow-up should be 3–5 years. However there isn’t any consensus about the periodicity of the follow-up.Aim: To evaluate the nodules in terms of function, size and malignancy in a 10-year follow-up.Methods: Retrospective study of 347 patients (543 benign thy...

The transcription factor Sox9 is a member of the HMG-box-DNA binding family essential for chondrocyte differentiation, sexual determination, and the maintenance of the stem/progenitor cells in several tissues. Furthermore, Sox9 is involved in the development of endoderm-derived-organs. Owing to the endodermic origin of the thyroid, we proposed to study the expression of Sox9 in thyroid follicular cells and its regulation by TSH and TGFβ, two main factors involved in thyro...

Introduction: ‘Atypia of undetermined significance (AUS) or follicular lesion of undetermined significance’ category is established by The Bethesda System for Reporting Thyroid Cytopathology because of the necessity to report those thyroid fine-needle aspiration (FNA) results that are not easily classified into the benign, suspicious or malignant categories. In most cases, a repeated FNA results in a more definitive interpretation. Estimated risk of malignancy for an...

Introduction: Knowing that only in 5–15% of FNABs the pathological analysis shows malignancy, enhance diagnostic accuracy is needed. The use of the TIRADS score and a revised version proposed by the British Thyroid Association (BTA) intend to determine if a FNAB should be performed or not in the evaluation of nodular goitre.Objective: To determine whether an adequate correlation is present between the risk category assigned to the nodules studied un...
