Background: TSH suppression therapy has been associated with hip and vertebral fracture. However, the relationship between TSH suppression and bone mineral density (BMD) remains controversial. The aim of this study was to evaluate the effect of TSH suppression therapy on cortical bone geometry in differentiated thyroid cancer (DTC) patients.Methods: This study included 122 subjects (19 men, 27 premenopausal women, and 75 postmenopausal women) who have be...

Introduction: Minimally invasive video-assisted thyroidectomy (MIVAT) was introduced for the treatment of selected patients. Our experience from 2005 indicates that outcome of surgery in differentiated thyroid cancer (DTC) is comparable in patients treated with MIVAT vs conventional thyroidectomy; minimally invasive technique is characterized by a better postoperative discomfort.Material and methods: In this prospective study from July 2005 to December 2...

Introduction: In recent years, micro papillary thyroid carcinomas (mPTCs; ≤1.0 cm) are increasingly diagnosed. Although clinical course is usually favourable, disease persistence may occur and multiple treatments needed. We examined factors that could be predictors of clinical behaviour and disease persistence.Patients and methods: 478 mPTC patients (78.9% females) followed-up for 0.6–10 years were classified according to tumour size in group ...

TIM16, a protein of the translocase complex TIM23 of the mitochondrial inner membrane, is encoded by the Magmas a gene. Magmas silencing has been associated with a greater sensitivity to apoptotic stimuli in pituitary adenoma cell lines. We recently demonstrated that in a human medullary thyroid carcinoma cell line (TT) compound 5, a TIM16 inhibitor, was not cytotoxic but enhanced the proapoptotic effects of staurosporine. The aim of our study is to verify whether mithocondria...

Previous studies have shown that Rituximab (RTX) is effective as a disease modifying drug at doses of 500 mg or 1000×2 mg in active Graves’ orbitopathy (GO). We have conducted a pilot study (EUDRACT 2012-001980-53) in which patients with active moderate-severe GO were treated with a single infusion of low dose RTX (100 mg). Ten patients were enrolled of whom seven completed the study at 52 weeks. Five patients did not respond to a previous treatment with i.v. methylp...

Context: High maternal TSH and/or low FT4 during pregnancy is associated with an increased risk of premature delivery. hCG is the main determinant of thyroid function changes during pregnancy but has a versatile pattern with high inter and intra-individual variability. We hypothesised that the correct interpretation of thyroid function tests and its use in the risk assessment of premature delivery during pregnancy depend on hCG levels.Design, ...

Thyroid storm (TS) is one extreme of a continuum beginning with thyrotoxicosis. It’s rarely caused by exogenous thyroid hormone intake (ETHI). Aggressive medical therapy is the cornerstone of treatment; nevertheless, it might not be sufficient. Plasmapheresis is an extracorporeal technique that can rapidly lower thyroid hormone levels. The aim of this study was to assess the efficacy of plasmapheresis in TS secondary to ETHI. We evaluated retrospectively all TS cases (Bur...

Graves’ orbitopathy (GO) is a common complication of Graves’ disease (GD) which is often responding poorly to therapy. GO may develop before or together with, or during the course of GD. In an individual patient, the development of GO cannot be predicted. We assumed that orbital autoimmune activity is predictable using orbital 99mTc-labelled diethylenetriamine pentaacetic acid (99mTc-DTPA) SPECT. We aimed to determine whether any orbital autoimmune activity can be id...
