Lithium as an adjuvant in the postoperative ablation of remnant tissue in low-risk thyroid carcinoma.

Background: Thyroid remnant ablation (RA) with 30 mCi of radioactive iodine (131I) in patients thyroidectomized for treatment of low-risk differentiated thyroid carcinoma (DTC) has a success rate of 64% to 84%. Lithium increases the residence time of 131I in the thyroid tissue. The aim of this study was to determine if lithium treatment added to 30 mCi 131I would enhance the success rate of this treatment compared with 30 mCi 131I alone in patients who were thyroidectomized for treatment of low-risk DTC.

[Evaluation of clinical, laboratorial and ultrasonographic predicting factors of malignancy in thyroid nodules].

Objective: To evaluate the risk of malignancy in thyroid nodules through clinical, laboratory, ultrasonographic and cytological aspects.

Patients And Methods: 741 nodules of 407 patients.

Results: The cytology was benign (60,5%), indeterminate (23,3%), malignant (8,3%) or nondiagnostic (7,6%).

Colchicine in the treatment of the inflammatory phase of Graves' ophthalmopathy: a prospective and randomized trial with prednisone.

Purpose: To investigate if colchicine is valuable in the treatment of Graves' ophthalmopathy (GO), we compared its effect with prednisone in 22 patients during the inflammatory phase of GO.

Methods: All patients, similar in age, sex and smoking habits, were euthyroid for at least 3 months and randomly divided into two groups, one treated with colchicine (1.5 mg/day) and the other treated with prednisone (0.
