Toxic multinodular goiter is a cause of nonautoimmune hyperthyroidism and is believed to differ in its nature and pathogenesis from toxic adenoma. Gain-of-function mutations of the TSH receptor gene have been identified as a cause of toxic adenoma. The pathogenesis at the molecular level of hyperfunctioning nodules in toxic multinodular goiter has yet not been reported. Six patients with a sing...

BACKGROUND Use of recombinant human thyrotropin increases the thyroid radioiodine (iodine 131 [(131)I]) uptake and may have a role in the context of (131)I therapy of benign goiter. METHODS In a double-blind, placebo-controlled trial, 57 patients with nodular nontoxic goiter (51 women and 6 men) were randomized to receive either 0.3 mg of recombinant human thyrotropin (n = 28) or placebo (n =...

SUMMARY In order to evaluate the long-ter m effects of antithyroids and ahlative therapy on patients with toxic diffuse goiter (TDG) in an iodine deficient region, 206 patients were studied in Tehran. Hyperthyroidism recurred in 50%, of 80 patients treated with Methimazole (MMI), from one week to 48 months after cessation of therapy. Another 40 patients remained in remission. Of 102 patients t...

Introduction: Hyperthyroidism is a relatively common disorder caused by different etiologies. Graves’ disease, and toxic-nodular goiter (Plummer’s disease) are among the most common causes. Treatment with radioiodine is considered to be the treatment of choice in many of the patients. Higher biological half-life of ¹³¹I in hyperthyroid patients as compared with patients with differentiate...
