Abstract Objective: Graves’ disease (GD) is the leading cause of hyperthyroidism globally, with 40% of affected individuals developing thyroid eye disease (TED). Treatment options for TED have advanced in recent years. This study aimed to investigate the prevalence of TED at a single center in Brazil, contributing more robust data for cost-analysis studies assessing the financial implications of novel TED treatments. Subjects and methods: This study evaluated the clinical histories of 660 patients diagnosed with GD from 1999 to 2019. […]

A 29 yrs-old patient was referred to our hospital due to generalized convulsions. She had hyperthyroidism treated with methimazole. Her MRI showed 4 metastatic lesions in the brain. She had a goiter with a “cold” nodule and a palpable ipsilateral lymph node. The FNAB disclosed a papillary thyroid carcinoma. Under 5 mg of MMI treatment, she had a subclinical hyperthyroidism and TRAb were 47.8% (n.v. < 10%). The CT scan also showed lung metastasis. She underwent a total thyroidectomy with […]

OBJECTIVE: To examine the factors associated with persistence or recurrence of hyperthyroidism following an initial therapy dose of 131 I. METHODS: Retrospective case-note review of all patients with hyperthyroidism treated with a fixed dose of 400 MBq 131 I at a single reference centre (1992 to 1997). From the 104 patients treated during that period, six had a multinodular goitre and one, a toxic adenoma; 96 were taking thionamide preparations, which were discontinued 7 days prior to radioiodine administration. RESULTS: […]
