1. Wnt3a but not CDX-2 expression is associated with differentiated thyroid cancer
SUMMARY OBJECTIVE: Thyroid neoplasm incidence has increased worldwide, mostly due to the advancements in medical imaging and screening rates. The aberrant Wnt/β-catenin pathway has been identified as a key mechanism, and it has also been related to the metastatic activity of differentiated thyroid cancer. We aimed to verify the difference in the expression

2. Preoperative vitamin D deficiency is a risk factor for postoperative hypocalcemia in patients undergoing total thyroidectomy: retrospective cohort study
ABSTRACT BACKGROUND: The relationship between preoperative vitamin D deficiency and postoperative hypocalcemia in cases of total thyroidectomy (TT) is a matter of controversy and may vary according to geographical scenarios and populations. OBJECTIVE: The objective here was to evaluate whether preoperative vitamin D deficiency was associated with postope

3. Preoperatively undiagnosed papillary thyroid carcinoma in patients thyroidectomized for benign multinodular goiter
ABSTRACT Objective Incidental thyroid cancers (ITCs) are often microcarcinomas; among them, the most frequent histotype is the papillary one. The purpose of this study was to evaluate the rate of papillary thyroid cancer (PTC) in patients thyroidectomized for benign multinodular goiter. Subject and methods We retrospectively evaluated the histological inci

4. Malignant melanoma with synchronous thyroid metastases: case report and literature review
SUMMARY Thyroid metastases are rare in clinical practice. We describe the case of an 85-year-old woman who was referred to our department due to a multinodular goiter with compressive symptoms and subclinical hyperthyroidism. The patient was also undergoing evaluation for a polyp in her left nasal cavity, which was then diagnosed as a malignant melanoma of t

5. Radio-contrast agent-induced hyperthyroidism: case report and review of the literature
SUMMARY A 66 year-old woman with a history of a euthyroid multinodular goiter underwent a head and neck computed tomography (CT) scan (total iodine load of 35 g) in order to evaluate the extent of retrosternal expansion. Less than 24 h after the iodine-based contrast media (ICM) administration, she presented with symptoms and laboratory findings typical of t

6. Thyroid nodule: first manifestation of chronic lymphocytic leukaemia
The presence of chronic lymphocytic leukaemia (CLL) cells in the thyroid gland is most likely due to a secondary involvement by a systemic disease. The reported incidence of CLL involving the thyroid is extremely low, representing about 3–4% of all thyroid lymphoproliferative neoplasm. We report a rare case of CLL presenting initially in the thyroid gland.

7. Radioiodine plus recombinant human thyrotropin do not cause acute airway compression and are effective in reducing multinodular goiter
Recombinant human thyrotropin (rhTSH) reduces the activity of radioiodine required to treat multinodular goiter (MNG), but acute airway compression can be a life-threatening complication. In this prospective, randomized, double-blind, placebo-controlled study, we assessed the efficacy and safety (including airway compression) of different doses of rhTSH asso

8. Multinodular goiter treatment with radioiodine aided by recombinant human TSH in different doses: a randomized, double-blind, placebo-controlled study / Administração prévia do TSH humano recombinante, em diferentes doses, no tratamento do bócio multinodular com iodo radioativo: um estudo randomizado, duplo cego, controlado com placebo
INTRODUÇÃO: Não há tratamento ideal para o bócio multinodular (BMN). A cirurgia é o método mais utilizado, por proporcionar uma redução imediata do volume tiroidiano (VT), dos sintomas compressivos e permitir um diagnóstico histológico definitivo. O iodo radioativo (I¹³¹) é considerado uma excelente opção terapêutica em situações de contr

9. O selênio e a glândula tireóide: um estudo em pacientes portadores de disfunções tireoidianas nos estados de Ceará e São Paulo / The selenium and thyroid gland: a study in patients with thyroid dysfunction in the states of Ceara and São Paulo
Introduction: The Selenium is a mineral essential to human, part of antioxidant mechanisms, influences the immune system and participates actively in homeostasis of the thyroid gland. Objective: To evaluate the nutritional status of selenium on adult patients bearers of hypothyroidism and hyperthyroidism in ambulatory care at the Hospital of the Faculty of M

10. Oxidant/antioxidant balance in patients with thyroid cancer
PURPOSE: To compare the antioxidant enzyme activities of superoxide dismutase (SOD), glutathione peroxidase (GSH-Px) and the levels of lipid peroxidation product malondialdehyde (MDA) in blood samples of thyroid cancer patients compared to healthy controls. METHODS: 43 control subjects (mean age 44±13 years) and 43 patients (43±13 years) presented with mul

11. Effect of 30 mCi radioiodine on multinodular goiter previously treated with recombinant human thyroid-stimulating hormone
Recombinant human thyroid-stimulating hormone (rhTSH) enhances 131I uptake, permitting a decrease in radiation for the treatment of multinodular goiter (MNG). Our objective was to evaluate the safety and efficacy of a single 0.1-mg dose of rhTSH, followed by 30 mCi 131I, in patients with MNG. Seventeen patients (15 females, 59.0 ± 13.1 years), who had never

12. Implicações do aumento da expressão do proto-oncogene Ras no bócio multinodular
O bócio multinodular (BMN) é definido como aumento da glândula tireóide devido a proliferação de tireócitos e caracteriza-se pela heterogeneidade no crescimento e função das células foliculares. É uma patologia comum, com aumento da prevalência em áreas com deficiência de iodo, sendo este o principal fator etiológico do BMN. O BMN é considera
