In 1923 the American physician Henry Stanley Plummer discovered that high-dose iodine may be effective in the treatment of Graves’ disease. [2] [3] Today, “Plummering”, i.e. therapy with Lugol's iodine solution, is one of several emergency measures in the management of severe thyrotoxicosis. [4]
Only the Wolff–Chaikoff effect is helpful to prevent the thyroid from uptaking radioactive iodine in the case of nuclear emergencies. Therefore, "plummering" with high-dose iodine is only effective in a short time window after the release of radionuclides. [15] Wrong timing of iodine use may even increase the risk by triggering the Plummer ...
In high dosage, iodine may reduce the synthesis of thyroid hormone via the Wolff–Chaikoff effect and its release via the Plummer effect. [5] Some guidelines recommend that iodine be administered after antithyroid medications are started, because iodine is also a substrate for the synthesis of thyroid hormone, and may worsen hyperthyroidism if ...
Saturated solutions of potassium iodide can be an emergency treatment for hyperthyroidism (so-called thyroid storm), as high amounts of iodide temporarily suppress secretion of thyroxine from the thyroid gland. [58] The dose typically begins with a loading dose, then 1 ⁄ 3 mL SSKI (5 drops or 250 mg iodine as iodide), three times per day.
The uptake test involves administering a dose of radioactive iodine (radioiodine), traditionally iodine-131 (131 I), and more recently iodine-123 (123 I). Iodine-123 may be the preferred radionuclide in some clinics due to its more favorable radiation dosimetry (i.e. less radiation dose to the person per unit administered radioactivity) and a ...
Iodine-131 (131 I, I-131) is an important radioisotope of iodine discovered by Glenn Seaborg and John Livingood in 1938 at the University of California, Berkeley. [3] It has a radioactive decay half-life of about eight days. It is associated with nuclear energy, medical diagnostic and treatment procedures, and natural gas production.
This is a form of targeted therapy for hyperthyroidism. Since even low levels of ionizing radiation are highly mutagenic and can cause cancer, [16] less toxic iodine isotopes such as iodine-123 [17] are more commonly used in nuclear imaging, while iodine-131 is used for its cytolytic (cell-destroying) effects in hyperthyroidism and thyroid ...
Thyroid diseases are highly prevalent worldwide, [10] [11] [12] and treatment varies based on the disorder. Levothyroxine is the mainstay of treatment for people with hypothyroidism, [13] while people with hyperthyroidism caused by Graves' disease can be managed with iodine therapy, antithyroid medication, or surgical removal of the thyroid ...
