Background: In the last decades, the clinical profile of PHPT in Western Countries has changed from a highly symptomatic to a largely asymptomatic disease. However, a substantial stability in its clinical features has been reported in the last two decades. The usual management, including time to diagnosis and treatment, of PHPT during the Covid-19 pandemic has been changed and likely slowed down. Whether further changes in the clinical presentation of PHPT have occurred during...

Introduction: The use of multigene panels in thyroid nodule diagnosis is still limited, due to high costs and need for ad hoc sampling. Since BRAF-V600E is the commonest genetic alteration in differentiated thyroid cancer, this is the mostly tested genetic parameter in clinical practice.Aim: To evaluate the use of BRAF mutation analysis in wash-out liquid from fine needle aspiration (FNA) in clinical practice, characterizing th...

Introduction: Hypothyroidism treatment is classically based on levothyroxine (LT4). However, 10% of hypothyroid patients treated with LT4 complain of hypothyroidism symptoms, despite normal thyroid stimulating hormone (TSH) serum levels. This ”peripheral hypothyroidism” has been linked to decreased availability of free triiodothyronine (fT3), likely related to single nucleotide polymorphisms (SNP) in deiodinase genes (DIO), reducing enzymatic activity. Since...

Introduction: Despite normal thyroid stimulating hormone (TSH) serum levels, 10% of hypothyroid patients treated with LT4 complain of hypothyroidism symptoms, likely linked to decreased availability of free triiodothyronine (fT3). Thus, combined levothyroxine/liothyronine (LT4/lT3) therapy was suggested to ensure a more physiological balance in peripheral tissues.Aim: To evaluate the effectiveness of combined LT4/lT3 therapy in thyroidectomized subjects,...

Introduction: Despite normal thyroid-stimulating hormone serum levels, up to 60% of hypothyroid patients are dissatisfied with the treatment. Animal studies suggest that the persistence of symptoms may derive from peripheral hypothyroidism. Combination treatment with levothyroxine and liothyronine is a theoretically plausible solution but its efficacy is still questionable.Aim: To evaluate the effects of personalized twice-daily combination therapy on pe...
