According wolff chaikoff effect hypothyroidism icd 9 newer theories, thyroid storm results from allostatic failure in a situation where thyrotoxicosis hampers the development of non-thyroidal effecct syndrome[11] which would help to save energy in critical illness and other situations of high metabolic demand. Dehydration, which occurs due to fluid loss from sweating, diarrhea, and vomiting, is treated with frequent fluid replacement. In larger amounts [potassium iodide] acts immediately to block further uptake of iodide by several means, particularly by saturating the iodide transport mechanisms of the thyroid, by inhibiting the intrathyroidal organification of iodide, and by simple dilution.

Possible explanations include a type Wolff chaikoff effect hypothyroidism icd 9 error, the absence of a biological effect, or concealment of a transient effect owing to the prolonged interval between ICM exposure and follow-up thyrotropin measurement. Hypothyroidism has been described most commonly in premature infants exposed to excess iodine by transcutaneous absorption of iodine-containing skin antiseptics 10and many newborn intensive care units have abandoned the routine use of these agents.

However, such interpretation must be tempered by realization that titers were measured in only a small possibly selected subset of cases, ICM exposure was similar among autoantibody-positive and autoantibody-negative cases, and the source population was drawn from an iodine-replete region.
