Triiodothyronine, also known as T3, is a thyroid hormone. It affects almost every physiological process in the body, including growth and development, metabolism, body temperature, and heart rate.
Common side effects include itchiness, hair loss, parotid swelling, vomiting, muscle pains, numbness, and headache. [3] Other severe side effects include liver problems and low blood cell counts. [3] Use during pregnancy may harm the baby. [3] Propylthiouracil is in the antithyroid family of medications. [4] It works by decreasing the amount of thyroid hormone produced by the thyroid gland and ...
Congenital iodine deficiency syndrome ( CIDS) is a medical condition present at birth marked by impaired physical and mental development, due to insufficient thyroid hormone ( hypothyroidism) often caused by insufficient dietary iodine during pregnancy. It is one cause of underactive thyroid function at birth, called congenital hypothyroidism, historically referred to as cretinism (obsolete ...
The primary treatment of thyroid storm is with inorganic iodine and antithyroid drugs ( propylthiouracil or methimazole) to reduce synthesis and release of thyroid hormone. Temperature control and intravenous fluids are also mainstays of management. Beta blockers are often used to reduce the effects of thyroid hormone. [5] Patients often require admission to the intensive care unit. [6]
The major form of thyroid hormone in the blood is thyroxine (T 4 ), whose half-life of around one week [4] is longer than that of T 3. [5] In humans, the ratio of T 4 to T 3 released into the blood is approximately 14:1. [6] T 4 is converted to the active T 3 (three to four times more potent than T 4) within cells by deiodinases (5′-deiodinase). These are further processed by decarboxylation ...
Wilson's (temperature) syndrome, also called Wilson's thyroid syndrome or WTS, is a term used in alternative medicine to improperly attribute various common and non-specific symptoms to abnormally low body temperature and impaired conversion of thyroxine (T4) to triiodothyronine (T3), despite normal thyroid function tests. E.
Treatment consists of a daily dose of thyroid hormone ( thyroxine) by mouth. Because the treatment is simple, effective, and inexpensive, most of the developed world utilizes newborn screening with blood thyroid stimulating hormone (TSH) levels to detect congenital hypothyroidism.
The thyroid is normally very resistant to infection. Due to a relatively high amount of iodine in the tissue, as well as high vascularity and lymphatic drainage to the region, it is difficult for pathogens to infect the thyroid tissue. Despite all this, a persistent fistula from the piriform sinus may make the left lobe of the thyroid susceptible to infection and abscess formation. [1] AIT is ...
