Efficacy of Low-Dose Radioiodine Ablation in Low- and Intermediate-Risk Differentiated Thyroid Cancer: A Retrospective Comparative Analysis.

(1) Background-low-dose radioiodine ablation is an accepted strategy for the treatment of low- and intermediate-risk thyroid carcinomas, although there is no international consensus. The aim of this study is to describe the clinical experience with low-dose radioiodine ablation in patients with low- and intermediate-risk thyroid cancer compared to high-dose ablation. (2) Methods-174 patients with low- and intermediate-risk thyroid cancer, 90 treated with low-dose ablation and 84 treated with high-dose ablation, were included.

New molecular biomarkers in differentiated thyroid carcinoma: Impact of miR-146, miR-221 and miR-222 levels in the evolution of the disease.

Objective: MircroRNAs (miR) are small, noncoding RNA molecules of 18-25 nucleotides. Their dysregulation has been widely studied in many human tumours including differentiated thyroid cancer (DTC). miRs more frequently associated with these kinds of tumours are miR-146, miR-221 and miR-222.

Adiponectin and leptin serum levels in osteoporotic postmenopausal women treated with raloxifene or alendronate.

Objective: Clinical studies evaluating the role of leptin and adiponectin on bone metabolism had shown conflicting results, and data about the effect of anticatabolic drugs on these adipokines are scarce. Our aims were to determine adiponectin and leptin levels in osteoporotic postmenopausal women and their relationship with bone mass and bone turnover and to analyze changes on adiponectin and leptin levels after treatment with raloxifene or alendronate.

Methods: We selected 53 women (mean ± SD age, 63 ± 7 y) with postmenopausal osteoporosis divided into two treatment groups: raloxifene (60 mg/d; n = 20) or alendronate (70 mg/wk; n = 33) during a period of 1 year.

[Clinical experience in a high-resolution thyroid nodule clinic].

Background And Objectives: The finding of a thyroid nodule is a very common occurrence in clinical practice. Management of thyroid nodules requires a multidisciplinary approach that may be eased by a high-resolution thyroid nodule clinic. We report our clinical experience and outcomes in a high-resolution thyroid nodule clinic.

Pituitary carcinomas.

Pituitary carcinoma is a extremely rare and is characterized by a very poor prognosis. Even if at diagnosis the presence of metastases is required to define a pituitary carcinoma, the lesion was almost invariably diagnosed first as a benign pituitary tumor, that after a variable period of latency, ranging from few months to many years, changed its natural course to an aggressive pituitary tumor poorly responsive to therapy. Recent studies have partially clarified its molecular pathogenesis and found possible markers of aggressiveness in order to make an earlier diagnosis, when still treatment could improve their prognosis.

Dramatic response to cholestyramine in a patient with Graves' disease resistant to conventional therapy.

Background: Resistance to the conventional treatment of hyperthyroidism with antithyroid drugs is not commonly found in clinical practice, and only few other treatment options have been reported on in detail. For example, surgery or radioiodine ablation are well-accepted interventions that must be always considered. The euthyroid state is strongly recommended before both of these as this might reduce complications.

Neonatal diabetes: genetic implications in treatment.

A 2-month-old newborn was diagnosed with diabetes mellitus presenting with ketoacidosis and negative islet antibodies. Genetic study revealed the R201C mutation of the KCNJ11 gene. In the last few years, the heterozygous activating mutation in KCNJ11 encoding the Kir6.
