BACKGROUND The purpose of this study was to investigate the impact of lymphocytic thyroiditis on incidence of incidental thyroid cancers. METHODS We conducted a retrospective review of 713 consecutive patients who underwent thyroidectomies. Incidental thyroid cancer was defined as an unexpected cancer discovered on pathological examination outside the index nodule undergoing preoperative cyto...

BACKGROUND Intensive vaccination protocols have been suggested as partially responsible for an increased prevalence of autoimmune diseases in dogs in recent years. The aim of this study was to determine whether repeated routine vaccination in dogs is associated with an increased prevalence of thyroiditis. METHODOLOGY/PRINCIPAL FINDINGS We conducted a prospective experimental study with 20 hea...

BACKGROUND Pyrexia of unknown origin is a difficult and challenging problem for the physician. Endocrine disorders, such as subacute thyroiditis, rarely present with pyrexia of unknown origin. Subacute thyroiditis can have a broad spectrum of clinical presentations including fever and biochemical thyrotoxicosis without overt signs or symptoms. CASE PRESENTATION A previously healthy 42-year-ol...

The serum T3 to T4 ratio is a useful indicator for differentiating destruction-induced thyrotoxicosis from Graves' thyrotoxicosis. However, the usefulness of the serum free T3 (FT3) to free T4 (FT4) ratio is controversial. We therefore systematically evaluated the usefulness of this ratio, based on measurements made using two widely available commercial kits in two hospitals. Eighty-two untreat...

We recently described a novel H2E class II-transgenic model (A(-)E(+)) of experimental autoimmune thyroiditis (EAT) that permits disease induction with heterologous thyroglobulin (Tg), but unlike conventional susceptible strains, precludes self-reactivity to autologous mouse Tg. In transgenic E(+)B10 (A(+)E(+)) mice, the presence of endogenous H2A genes is protective against H2E-mediated thyroi...

Enteroviruses, including coxsackieviruses and Echovirus, are well known pathogens responsible for the development of thyroiditis. We describe the case of a 49-year-old woman with no personal or family history of thyroid disease who presented to the emergency room with a two-week history of daily fevers up to 39°C, a sore throat, occasional palpitations and diaphoresis, decreased appetite and an...

Autoimmune disorders encompass a wide spectrum of diseases that progress with several clinical findings. They can be organ-specific (such as Hashimoto's thyroiditis) or they can involve multiple organs (such as SLE). The common characteristic of all these disorders is the production of different autoantibodies against various autoantigens along with inflammation. IgA nephropathy is the most com...

Noonan syndrome is an autosomal dominant, multisystem disorder. Autoimmune thyroiditis with hypothyroidism is an infrequent feature in patients with Noonan syndrome. A 16-year-old boy was admitted because of chest discomfort and dyspnea; an echocardiogram revealed pericardial effusion. Additional investigations led to a diagnosis of severe hypothyroidism due to Hashimoto thyroiditis. The patien...

BACKGROUND Acute suppurative thyroiditis is an increasingly rare entity, accounting for less than 0.1% of thyroid surgery. This is the first report in the literature of acute thyroiditis causing a unilateral reversible vocal cord paralysis. METHODS A 41-year-old woman was initially seen with a unilateral vocal cord paralysis resulting from acute suppurative thyroiditis. RESULTS The vocal co...

Thyroiditis should be in the differential for hyperthyroidism when thyroid-stimulating hormone (TSH) is suppressed and T3/T4 levels are elevated. Suspicion of further increased patient can exhibit symptoms such as weight loss, anxiety, feeling feverish, tremors, shaking, sweating. Hyperthyroidism generally classified being overt or subclinical. In following case, had which considered more sever...
