Context: Thyrotoxicosis is the most common endocrine adverse event due totreatment with anti-PD1 and anti-PD-L1. The most common form is destructive thyrotoxicosis whereas persistent, supposedly autoimmune hyperthyroidism (Graves’ hyperthyroidism) is rare. The possible role of thyroid imaging (neck ultrasound and scintigraphy) in the differential diagnosis has never evaluated.Aim: To evaluate the usefulness of neck ultrasound and 99Tc- s...

Objective: Thyroid nodules (TN) are extremely common in the general population. Data on long-term follow-up of benign nodular thyroid disease are limited. The aim of our study was to evaluate the changes in ultrasound features in a group of patients with TN.Methods: We retrospectively collected data about ultrasound features of 228 nodules from 153 consecutive patients with mean age 54.73±11.55 years [125 F (81.7%), 28 M (18.3%)], followed for a media...

Background and Objectives: During pregnancy normal thyroid activity undergoes significant changes, including an increase in the amount of iodine intake and maternal renal iodine excretion. Hence, dietary iodine requirements are higher in pregnant women than in non-pregnant ones. This study aimed to assess the nutritional iodine status in a large group of pregnant women and thyroid function according to different iodine intake and thyroid diseases.Methods...

Background: In recent years, increasing cases of congenital hypothyroidism (CH) with in situ thyroid gland are identified. Outcome of children affected from CH with normally sited thyroid of normal size is still unknown. The objective of our study is to describe the natural history of this specific form of CH. Patients and methods: We retrospectively evaluated clinical, biochemical and instrumental data of 74 patients with diagnosis of CH with in situ thyroid...

Introduction: Congenital hypothyroidism (CH) with in situ thyroid gland (GIS) and non-autoimmune subclinical hypothyroidism (NASI) are functional defects of thyroid gland occurring at birth and after birth, respectively. In recent years, a higher incidence of these disorders has been documented. The etiology remains unclear, with only an almost 50% of cases attributable to mutations in known dyshormonogenesis-associated or TSH-receptor genes. Although replacement ther...

Background: In recent years, increasing cases of congenital hypothyroidism (CH) with in situ thyroid gland (GIS) are identified. Outcome of children affected from CH with normally sited thyroid of normal size is still unknown. The objective of our study is to describe the natural history of this specific form of CH.Methods: We retrospectively evaluated clinical, biochemical and instrumental data of 89 patients with diagnosis of CH and GIS, refer...

Objectives: The association between thyroid function variations and body mass index (BMI) has been described in the adult population in several studies: higher TSH values and lower FT4 values, while still within reference range, have been correlated with higher BMI values. The aim of the study was to assess thyroid hormones variations in relation to body weight in pregnant women without thyroid diseases.Methods: In this prospective study, thyroid functio...

Objective: Destructive thyroiditis is the most common endocrine immune related adverse event (iRAEs) in patients treated with anti-PD1/PD-L1 agents. Given its self-limited course, current guidelines recommend no treatment for this iRAE. Nevertheless in patients with enlarged thyroid volume and a poor performance status, thyrotoxicosis may be particularly severe and harmful. Aim of the study is to evaluate if steroid treatment might be useful in improving thyrotoxicosis in subj...

Introduction: Congenital hypothiroidism (CH) is the most common neonatal endocrine disorder, affecting up to one in 1500 to 2000 newborns, if mild forms of hypothyroidism with eutopic and normal-sized thyroid gland are included. It is caused by either dysgenesis or dyshormonogenesis. Recently a novel iodide transporter, SLC26A7 (a member of the SLC26 transporter family), whose dysfunction affects thyroid hormonogenesis in humans, has been identified. The main purpose of this s...

The insecticide DDT has been shown to inhibit both the basal and the TSH stimulated accumulation of cAMP in CHO stably transfected with the TSHr (CHO-TSHr). Aim of this study was to evaluate whether the DDT has a similar effect on cells transfected with TSHr mutants displaying a high level of constitutive activity. In addition we investigate the effect of DDT on cells transfected with wtFSHr and wtLHr which share a high degree of amino-acid homology sequence with wtTSHr. In co...
