Thyrotoxicosis is a hypermetabolic condition caused by an elevation in thyroid hormone levels. The disorder has a variety of causes, manifestations, and therapies. Several clinical features of thyrotoxicosis are due to sympathetic stimulation with increased beta-adrenoreceptor upregulation and sensitization to catecholamine. Anaesthetic management of thyrotoxicosis patients using neuraxial bloc...

BACKGROUND Thyrotoxicosis is common in the Australian community and is frequently encountered in general practice. Graves disease, toxic multinodular goitre, toxic adenoma and thyroiditis account for most presentations of thyrotoxicosis. OBJECTIVE This article outlines the clinical presentation and evaluation of a patient with thyrotoxicosis. Management of Graves disease, the most frequent ca...

OBJECTIVE To characterize thyroid hormone levels at the time of diagnosis in the nosological types of thyrotoxicosis diagnosed in the population and to analyze determinants for serum thyroxine (T4) and tri-iodothyronine (T3). DESIGN Population-based study of thyrotoxicosis at disease onset. METHODS In the period 1997-2000, we prospectively identified all patients diagnosed with incident pri...

Thyrotoxicosis is defined as the clinical syndrome of hypermetabolism resulting from increased free thyroxine (T4) and/or free triiodothyronine (T3) serum levels (1). The term thyrotoxicosis is not synonymous with hyperthyroidism, the elevation in thyroid hormone levels caused by an increase in their biosynthesis and secretion by the thyroid gland (Table 1) (2). For example, thyrotoxicosis can ...

Thyrotoxicosis along with its usual signs and symptoms like palpitation, weight loss, tremors, sweating, heat intolerance, diarrhea, exophthalmos, tachycardia, and warm extremities, can also present with gynaecomastia and as many as 80% of the patients may have histological evidence of gynaecomastia 1-4 . Although association of thyrotoxicosis with gynaecomastia is well documented, its presenta...

BACKGROUND Thyrotoxicosis is a common disease caused by an excess of thyroid hormones. The prevalence of thyrotoxicosis about 2% and 70-90% of thyrotoxicosis cases are caused by Graves' disease, an autoimmune disease, which has a high recurrence rate when treated with antithyroid drugs such as methimazole or propylthiouracil. The clinical symptoms and signs of thyrotoxicosis include palpitation...

Thyrotoxicosis is a term used to describe any condition in which there is an excessive amount of circulating thyroid hormone whether from excess production and secretion from an overactive thyroid gland, leakage from a damaged thyroid gland, or from an exogenous source. In most veterinary patients, thyrotoxicosis occurs from thyroid gland hyperfunction. Feline hyperthyroidism is a common endocr...

Aim: Thyrotoxicosis is a clinical state of inappropriately high levels free T4 (thyroxine) and/or T3 (tri-iodothyronine) in the body caused by distinct etiologies including Graves’ disease (GD), subacute thyroiditis (SAT), toxic adenoma and multinodular goiter (TMNG). Simple hematologic indices such as neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte (PLR) mean platelet volume (MPV) have ...

" Scire est nescire, nisi id me Scire alius sciret SPRING, 194:1. It would not be possible to deal at all fully with the scientific aspects of this subject in an article of reasonable length, and still less would it be possible to give a resume of the enormous literature that has grown up concerning it. My purpose is much simpler ; it is to present a record of personal experience and to offer s...
