An autonomous thyroid nodule or "hot nodule" is one that has thyroid function independent of the homeostatic control of the HPT axis (hypothalamic–pituitary–thyroid axis). According to a 1993 article, such nodules need to be treated only if they become toxic; surgical excision (thyroidectomy), radioiodine therapy, or both may be used. [32]
Thyroid follicular adenoma ranges in diameter from 3 cm on an average, but sometimes is larger (up to 10 cm) or smaller. The typical thyroid adenoma is solitary, spherical and encapsulated lesion that is well demarcated from the surrounding parenchyma. The color ranges from gray-white to red-brown, depending upon the cellularity of the adenoma
Curative therapy is indicated in early stages, which include very early stage (single nodule <2 cm), curable by surgical resection (survival 50-70% five years after surgical resection) and early stage (single nodule of 2–5 cm, or up to 3 nodules <3 cm) which can be treated by radiofrequency ablation (RFA) and liver transplantation.
Euthyroid sick syndrome (ESS) is a state of adaptation or dysregulation of thyrotropic feedback control [1] wherein the levels of T3 and/or T4 are abnormal, but the thyroid gland does not appear to be dysfunctional.
Although thyroid nodules are common, thyroid cancer is rare. Thyroid cancer accounts for less than 1% of all cancer in the UK, though it is the most common endocrine tumor and makes up greater than 90% of all cancers of the endocrine glands. [40]
About one in 10 people is found to have solitary thyroid nodules. Investigation is required because a small percentage of these is malignant. Biopsy usually confirms the growth to be an adenoma, but, sometimes, excision at surgery is required, especially when the cells found at biopsy are of the follicular type.
Novo Nordisk’s latest attempt in weight loss, a combination drug called CagriSema, matched the bar set by Lilly’s currently approved medicine, Zepbound, but didn’t cleanly surpass it in late ...
Thyroid function tests will help reveal whether the nodule produces excess thyroid hormones. A radioactive iodine uptake test can help reveal the activity and location of the cancer and metastases. [67] [69] Thyroid cancers are treated by removing the whole or part of thyroid gland. Radioactive Iodine-131 may be given to radioablate the thyroid.
