Iodine-131 (usually as iodide) is a component of nuclear fallout, and is particularly dangerous owing to the thyroid gland's propensity to concentrate ingested iodine and retain it for periods longer than this isotope's radiological half-life of eight days. For this reason, people at risk of exposure to environmental radioactive iodine (iodine ...
Iodine deficiency is a lack of the trace element iodine, an essential nutrient in the diet. It may result in metabolic problems such as goiter , sometimes as an endemic goiter as well as congenital iodine deficiency syndrome due to untreated congenital hypothyroidism , which results in developmental delays and other health problems.
These drugs block the binding of iodine and coupling of iodotyrosines. The most dangerous side effect is agranulocytosis (1/250, more in PTU). Others include granulocytopenia (dose-dependent, which improves on cessation of the drug) and aplastic anemia. Patients on these medications should see a doctor if they develop sore throat or fever.
Iodine is the fourth halogen, being a member of group 17 in the periodic table, below fluorine, chlorine, bromine; since astatine and tennessine are radioactive, iodine is the heaviest stable halogen. Iodine has an electron configuration of [Kr]5s 2 4d 10 5p 5, with the seven electrons in the fifth and outermost shell being its valence electrons.
It is the most common cause of hypothyroidism in areas of sufficient iodine. [10] Also, the rate of lymphocytic infiltration increased in areas where the iodine intake was once low, but increased due to iodine supplementation. [27] [119] Iodine deficiency disorder is combated using an increase in iodine in a person's diet.
“There is no medication without risk. People die every year from aspirin. People have penicillin allergies,” he said. Kleber has been a pioneer in the use of medically assisted treatments since founding a methadone clinic in the ’60s, and he was among the first to open a Suboxone clinic in the U.S.
A radioactive iodine uptake test and thyroid scan together characterizes or enables radiologists and doctors to determine the cause of hyperthyroidism. The uptake test uses radioactive iodine injected or taken orally on an empty stomach to measure the amount of iodine absorbed by the thyroid gland.
Seafood "allergy" is not a contraindication for the use of iodinated contrast materials, because in seafood allergy the immune system is directed against the muscle protein tropomyosin. While iodine levels in seafood are higher than in non-seafood items, the consumption of the latter exceeds that of the former by far and there is no evidence ...
