iodine poisoning

An acute condition caused by accidental ingestion of iodine or its compounds. This condition is marked by brown stains on the lips and mouth; burning pain in the mouth, throat, and stomach; vomiting (blue vomit if the stomach contained starches, otherwise yellow vomit); bloody diarrhea.

Patient care

The patient should immediately be given by mouth a cornstarch or flour solution, 15 g in 500 ml (2 cups) of water. Activated charcoal or gastric lavage may also be employed.

iodine

a chemical element, atomic number 53, atomic weight 126.904, symbol I. See Table 6. Iodine is essential in nutrition, being especially prevalent in the colloid of the thyroid gland. It is used in the treatment of hypothyroidism and as a topical antiseptic. Iodine is a frequent cause of poisoning. See also iodism.

iodine-125
a radioisotope of iodine having a half-life of 60 days and a principal gamma-ray photon energy of 28 keV; used as a label in radioimmunoassays and other in vitro tests, and also for thyroid imaging. Symbol 125I.
123iodine-metaiodobenzylguanidine
a radioisotope which concentrates in chromaffin cells; used in diagnostic scintigraphy, e.g. in cases of pheochromocytoma.
iodine-131
a radioisotope of iodine having a half-life of 8.1 days and a principal gamma-ray photon energy of 364 keV; used in treatment of hyperthyroidism and carcinoma of the thyroid, in thyroid function testing, and in imaging of the thyroid gland and other organs. Symbol 131I.
iodine deficiency
may occur in all species under certain conditions; in dogs and cats, a factor in all-meat diets. See also goiter.
iodine contrast agents
iodine salts are opaque to x-rays; therefore they can be combined with other compounds and used as contrast media in diagnostic x-ray examinations.
iodine nutritional deficiency
is characterized by goiter, neonatal mortality and alopecia.
iodine poisoning
occurs usually due to accidental overdosing. It causes lacrimation, anorexia, coughing due to bronchopneumonia, and a heavy dandruff. Paradoxically, iodine excess may result in thyroid hyperplasia and goiter, especially in the young.
protein-bound iodine
a test of thyroid function. See also protein-bound iodine (PBI) test.
radioactive iodine
see iodine-125, iodine-131 (above).
iodine residues in milk
careless use of iodine-based teat dips results in unacceptable residues of iodine in milk.
iodine solution
contains 2% free iodine and 2.4% sodium iodide in an aqueous solution.
iodine solution (strong)
contains 5% free iodine and 10% potassium iodide in an aqueous solution.
tamed iodine
iodine trapping
the selective absorption of iodine from the circulation by the thyroid gland.
