Introduction: Papillary thyroid carcinoma (PTC) is the most common endocrine malignancy, with a steadily increasing incidence in the last few decades worldwide. Studies revealed the predisposition to PTC by the heterozygous state of rs2910164 within the precursor of microRNA146a. Interestingly, on the same chromosome, 40Kb separate the pre-miR-146a from the pituitary tumour transforming gene (PTTG1), a proto-oncogene involved in thyroid carcinomas. A genome-w...

Introduction: Thyroid volume (TV) depends on age, gender, anthropometry, smoking and iodine status. IGF1 plays a role on thyroid growth, as demonstrated in acromegaly and GH-deficiency. Finally, TSH is a well recognised permissive factor for thyroid tissue growth. The aim of the study is to evaluate the long-term effect of TSH-deficiency on TV in hypopituitaric patients compared with healthy volunteers.Methods: We performed a cross-sectional, controlled ...

Background: Thyroid nodules represent a common clinical finding and their prevalence is increasing worldwide. However, the most recent international guidelines do not give indications on the need to retest adults with previous negative neck ultrasound (US).Aim: To evaluate the incidence of thyroid US abnormalities in patients with previous negative thyroid US and identify patient’s characteristics able to predict the risk of developing thyroid disea...
