Strain 13 histocompatible guinea pigs developed allergic thyroiditis after immunization with thyroid extracts derived from the same strain or from other strains of guinea pigs. This thyroiditis appeared as early as 5 days after immunization, and by 7 weeks was uniformly present and generally severe. 7 weeks after immunization, the anti-thyroid antibody titer correlated with the presence and deg...

Subacute thyroiditis is generally felt to have a viral etiology, and the diagnosis is usually obvious when the patient presents with a diffusely enlarged and very tender thyroid gland associated with elevated free T4 levels, elevated sedimentation rate, low radioiodine uptake and/or nonvisualization on scan and often some systemic symptoms. Subacute thyroiditis can be unilateral or focal (1,2)....

Thyroiditis is an inflammatory condition of the thyroid gland. It has been reported that thyroiditis is currently ranked the third autoimmune disease in the United States and has a staggering estimated prevalence of 21.8/100,000 (Burek et al., 2009). This is a well-established condition and many aspects of its etiology are also well known. According to the 2005 data of the American Thyroid Asso...

Hashimoto's thyroiditis has been reported to be associated with many neoplastic and nonneoplastic thyroid pathologies. This retrospective study aims to determine the demographic profile of Hashimoto's thyroiditis in Sri Lankans, document ancillary pathologies in Hashimoto's thyroiditis, and determine whether there is an increased risk of occurrence of malignancies, benign neoplasms, and nonneop...

Riedel's thyroiditis is a rare disorder of unknown etiology and may be seen isolated or as a part of multifocal fibrosclerosis. It is important to distinguish Riedel's thyroiditis from thyroid carcinoma. Reports about imaging features of Riedel's thyroiditis are limited in the radiologic literature. We describe herein CT and MR imaging features of Riedel's thyroiditis in a case of multifocal fi...

Background: This study aims to research the relationship of subacute thyroiditis with SARS-CoV-2. The prevailing risks predisposition certain diseases or organ dysfunctions even after surviving disease are discussed more frequently each day. Aim: Could SARS-CoV-2 be considered as a triggering factor in patients diagnosed thyroiditis? Investigating between and Methods: Thirty-three 01.11.2020 01...

conclusions thyroid dysfunction was not higher in sle patients compared to healthy individuals. however, anti-tg antibodies were higher in sle patients. it has not yet been established that thyroid function tests should be performed routinely in sle patients. results the mean age of sle patients and controls were 32.16 ± 9.19 and 32.48 ± 9.47 years, respectively (p = 0.821). patients had signif...

Alpha interferon (alphaIFN) therapy is known to induce thyroid autoimmunity in up to 40% of patients. The mechanism is unknown, but Th1 switching has been hypothesized. The aim of our study was to examine whether alphaIFN accelerated the development of thyroiditis in genetically susceptible mice. We took advantage of NOD-H2h4, a genetically susceptible animal model, which develops thyroiditis w...

A case of autoimmune thyroiditis after long term treatment with lithium is described in a 29 year old Japanese woman with manic depression. Positive serum antithyroglobulin and antimicrosomal antibodies, diffuse goitre, and microscopic chronic thyroiditis, as well as the clinical history of long term lithium treatment were suggestive of lithium associated autoimmune thyroiditis. Microscopically...
