The presented work describes the thyroid pathologies and nuclear-medical diagnostic approach, in order to obtain a differential diagnosis monitoring of various neoplasms; specifically, it importance radiometabolic treatment with iodine 131, after thyroidectomy surgery. Through study conducted patients suffering from disease, undergoing metabolic radiotherapy, is shown that, equal distribution r...

OBJECTIVE To determine the effect of adjunctive antithyroid drugs on the risk of treatment failure, hypothyroidism, and adverse events after radioiodine treatment. DESIGN Meta-analysis. DATA SOURCES Electronic databases (Cochrane central register of controlled trials, Medline, Embase) searched to August 2006 and contact with experts. Review methods Three reviewers independently assessed tri...

Introduction:Differentiatedthyroid carcinoma (DTC) constitute approximately 90% of all thyroid tumors with an overall excellent prognosis. However, there is a small group of patients with a more aggressive form of disease, usually associated with certain poor prognostic factors. Using our large database of patients with DTC, the current study aims at identifying some of these f...

Radioiodine-concentrating activity in thyroid tissues has allowed the use of radioiodine as a diagnostic and therapeutic agent for patients with thyroid disorders such as well-differentiated thyroid cancer. However, some extrathyroidal tissues also take up radioiodine, contributing to unwanted side effects of radioiodine therapy. Now that the molecule that mediates radioiodine uptake, the sodiu...

OBJECTIVE To evaluate the effects of pretreatment with the retinoid X receptor (RXR) agonist bexarotene on the efficacy of radioiodine therapy for metastases of differentiated thyroid carcinoma (DTC) with limited uptake of radioiodine (I-131). DESIGN An open prospective intervention study. METHODS Eight patients with metastases of DTC, with insufficient uptake of I-131 who showed increased ...

Various studies have demonstrated the safety and efficacy of recombinant human thyroid-stimulating hormone (rhTSH) for radioiodine remnant ablation. On this basis, rhTSH was approved in Europe for the radioiodine ablation of low-risk differentiated thyroid cancer (DTC) during thyroid hormone therapy with L-thyroxine (L-T4). Moreover, in December 2007, the US Federal Drug Administration approved...

BACKGROUND Radioiodine treatment of hyperthyroidism in Graves' disease patients may cause or aggravate the course of ophthalmopathy (GO). We evaluated the activity and severity of ophthalmopathy in patients who acquired GO following radioiodine therapy. MATERIAL AND METHODS Between 2003 and 2005, 763 Graves' disease patients (50.9% of the total number of 1,500 patients referred to our Departm...

We experienced a case with Graves' disease in which radioiodine treatment failed probably because of intentional spitting out of capsules of radioactive iodide. Chemical analysis of the substances collected from the trash in the treatment room demonstrated that its profile was the same as that of the capsules for radioiodine administration. Measurement of the iodine concentrations in a blood sa...

We investigated the effect of a single dose of 131I upon thyrotropin receptor antibodies (TRAb) in 21 patients with Graves' disease. The thyrotropin receptor antibodies were assessed by parallel measurements of thyrotropin binding inhibitor immunoglobulin (TBII), thyroid stimulating antibody (TSAb), and thyroid stimulation blocking antibody (TSBAb) in serum by radioreceptor assay, stimulation o...
