CONTEXT AND OBJECTIVE Celiac disease is an autoimmune disorder with an average prevalence of 1% in Europe and the United States. Because of strong European ancestry in southern Brazil, this study aimed to evaluate the seroprevalence of celiac disease among autoimmune thyroiditis patients. DESIGN AND SETTING Cross-sectional study in a public university hospital. METHODS This cross-sectional ...

PURPOSE The aim of this study was to evaluate the clinicopathologic characteristics of papillary thyroid cancer with thyroiditis, and to determine the rate of its complications for it. METHODS A retrospective review of 1,247 patients with papillary thyroid cancer who underwent primary thyroidectomy was performed. Among them, 316 patients had thyroiditis (group I) while 931 patients had no thy...

CONTEXT When the liver function tests are aggravated after starting antithyroid drugs (ATDs) in Graves' hyperthyroidism, discontinuation of ATDs is generally considered. However, a question arises whether such aggravation constitutes an adverse effect of the drugs or not. OBJECTIVE The aim of this study was to clarify the influence of thyrotoxicosis on liver function tests, comparing the resu...

OBJECTIVE The objective of this study is to evaluate the link between excess iodine intake as evidenced by increased urinary iodine excretion (UIE) and autoimmune thyroiditis in children and to assess the correlation between UIE and thyroid microsomal antibody (thyroid peroxidase [TPO]) titers in children. MATERIALS AND METHODS All children with goiter between age group 6 and 12 years, were s...

Hashimoto’s thyroiditis (HT) is an autoimmune disease with genetic background. It is also named as autoimmune thyroiditis or chronic lymphocytic tiroiditis. Hashimoto's thyroiditis is the most common cause of thyroid diseases in children and adolescents and it is also the most common cause of acquired hypothyroidism with or without goiter. Hashimoto’s thyroiditis was first described in 1912 by ...

BACKGROUND Autoimmune thyroid disease is a common complication of patients with chronic hepatitis C undergoing combination pegylated interferon-α and ribavirin treatment. A small proportion develops interferon-induced thyroiditis of which the long term natural history is unknown and how it compares with de novo thyroiditis. The aim of the study is to determine the natural history of thyroid dis...

In 43 patients with Graves' disease, 5 patients with painless thyroiditis and 30 patients with Hashimoto-thyroiditis ultrasonographical observations and histological examinations by needle biopsy of the thyroid were carried out simultaneously. In all cases the level of echo-amplitude was well correlated with the rate of lymphocytic infiltrations and fibrosis. In cases which exhibited marked lym...

Thyroiditis is a general term that encompasses several clinical disorders characterized by inflammation of the thyroid gland. The most common is Hashimoto thyroiditis; patients typically present with a nontender goiter, hypothyroidism, and an elevated thyroid peroxidase antibody level. Treatment with levothyroxine ameliorates the hypothyroidism and may reduce goiter size. Postpartum thyroiditis...

A 36-year-old woman with postpartum hypopituitarism (Sheehan's syndrome: SS) developed postpartum autoimmune thyroiditis (PPAT). She delivered a baby by Caesarean section (620 mL blood loss). At 1 month post partum, she developed thyrotoxicosis due to painless thyroiditis (autoimmune destructive thyroiditis). She was positive for antithyroid antibodies. Postpartum and hypoadrenalism-induced exa...

INTRODUCTION Riedel's thyroiditis, a rare thyroid disease, can be difficult to diagnose prior to surgical removal and can be confused with malignancy both clinically and cytologically. CASE PRESENTATION We report the case of a 72-year-old Caucasian woman who presented with a goiter, which showed a rapid increase in size at ultrasound check, suggesting malignancy. Because of inconclusive cytol...
