Introduction: The approach for initial thyroid hormone suppression in patients who undergo surgery for differentiated thyroid cancer (DTC), is based upon the risk of disease recurrence. In particular, recent American Thyroid Association guidelines suggest to maintain TSH levels between 0.1 and 0.5 mU/l and less than 0.1 mU/l for patients with ‘intermediate’ and ‘high’ risk respectively. The aim of the study is to identify the major predictive factors of LT4...

Background: In a previous publication we identified the major predictive factors of levothyroxine (LT4) requirement and proposed an efficient nomogram to calculate LT4 substitutive starting dose after total thyroidectomy for benign disease. The aim of this study was to assess whether the LT4 requirement differs between the tablet and the soft gel capsules formulations.Methods: One hundred and three consecutive patients su...

Introduction: Differentiated thyroid cancer (DTC) is the most frequent endocrine cancer. After surgery followed, if any, by 131I radio remnant ablation (RRA), follow-up monitoring consists of neck ultrasonography (US) and measurements of thyroglobulin (Tg) levels and anti-Tg antibodies (Ac-Tg) both on levothyroxine (L-T4) therapy and after recombinant TSH (rTSH). The aim of our study is to define a cut-off of Tg before RRA (RRA-Tg) during <...

A 73 years old man came to our observation for severe dysphagia and loss of weight (10 kg in 1 month). About 30 years before he had myocardial infarction and he underwent coronary artery bypass graft. One week before the first medical evaluation, patient suspended all drugs per os because he could not swallow pills and food. Thyroid function test revealed a severe hyperthyroidism (FT3 11.9 pg/ml; FT4 40 pg/ml; TSH <0.01 μU/ml). Anti-TSH ...

Chronic obstructive pulmonary disease (COPD) patients could have altered endocrine function as different endocrine organs (gonads, pituitary, thyroid and pancreas) can be affected depending on the phenotype of the disease and the degree of systemic inflammation. Anabolic hormones can be involved as COPD patients can show weight loss and muscle wasting and both these conditions can modify natural history of the disease. Moreover COPD patients can frequently have acute exacerbat...

Oxidative stress is associated with chronic alcoholic abuse; it is also a mechanism involved in male infertility. To further investigate the relationships between these two conditions, we studied 6 patients with diagnosis of Alcohol Dependence (DSM-IV) during post-detoxification phase, who consulted our centre for infertility. We evaluated seminal parameters, hormone pattern, Total Antioxidant Capacity (TAC) and the lipophilic antioxidant Coenzyme Q10 (CoQ10), both in blood an...
