Antithyroid drugs sometimes cause severe complications. Propylthiouracil (PTU) can be associated to ANCA positive vasculitis, most often related to myeloperoxidase subtype (ANCA-MPO). Our objective is to describe a female patient with Graves' disease, who developed PTU induced-autoimmune disease, with cutaneous, pulmonary, and renal lesions, associated with(More)
Thyroid nodules are frequent findings, especially when sensitive imaging methods are used. Although thyroid cancer is relatively rare, its incidence is increasing, particularly in terms of small tumors, which have an uncertain clinical relevance. Most patients with differentiated thyroid cancer exhibit satisfactory clinical outcomes when treatment is(More)
OBJECTIVE The objective of this study was to evaluate the efficacy and safety of percutaneous ethanol injection (PEI) in the treatment of benign thyroid nodules. SUBJECTS AND METHODS We evaluated 120 patients with benign thyroid nodules. Patients underwent evaluation of serum TSH and free T4, cervical ultrasound, and thyroid scintigraphy (in those with(More)
Thyroid nodules are a common manifestation of thyroid diseases. It is estimated that approximately 10% of adults have palpable thyroid nodules with the frequency increasing throughout life. The major concern on nodule evaluation is the risk of malignancy (5-10%). Differentiated thyroid carcinoma accounts for 90% of all thyroid malignant neoplasias. Although(More)
BACKGROUND Congenital hypothyroidism (CH) is mainly due to developmental abnormalities leading to thyroid dysgenesis (TD). TD encompasses very distinct morphologic subtypes of disease. This study examined and compared the phenotype in TD variants and searched for genetic alterations in sporadic thyroid hypoplasia (TH), the most misdiagnosed form of CH. This(More)
We herein report the case of a 51-year-old woman, who presented with a large goiter (250-300 g on palpation) with extension to the mediastinum and compression of the trachea causing dyspnea and with associated lumbar pain. Although two fine-needle aspiration biopsies of the gland were negative, a biopsy of a lesion in the spine shown on computed tomography(More)

Thyroid Nodules and Differentiated Thyroid Cancer: Brazilian Consensus. Thyroid nodules are a common manifestation of thyroid diseases. It is estimated that ~10% of adults have palpable thyroid nodules with the frequency increasing throughout life. The major concern on nodule evaluation is the risk of malignancy (5–10%). Differentiated thyroid carcinoma(More)
Laboratory tests are essential for accurate diagnosis and cost-effective management of thyroid disorders. When the clinical suspicion is strong, hormonal levels just confirms the diagnosis. However, in most patients, symptoms are subtle and unspecific, so that only biochemical tests can detect the disorder. The objective of this article is to do a critical(More)
OBJECTIVE Compliance to levothyroxine treatment in hypothyroidism is compromised by daily schedule, and a weekly dose may be an alternative. SUBJECTS AND METHODS This was a randomized, crossover study. Fourteen females were assigned to daily or weekly doses of LT4. After six weeks, they switched regimens. Thyroid parameters were measured at baseline, and(More)
