Acute radiodermatitis occurs when an "erythema dose" of ionizing radiation is given to the skin, after which visible erythema appears up to 24hrs after. Radiation dermatitis generally manifests within a few weeks after the start of radiotherapy. Acute radiodermatitis, while presenting as red patches, may sometimes also present with desquamation or blistering. Erythema may occur at a dose of 2 Gy radiation or greater.
Famous quotes containing the word acute:
“Strictly speaking, there is but one real evil: I mean acute pain. All other complaints are so considerably diminished by time that it is plain the grief is owing to our passion, since the sensation of it vanishes when that is over.”
—Mary Wortley, Lady Montagu (16891762)
“Only the most acute and active animals are capable of boredom.A theme for a great poet would be Gods boredom on the seventh day of creation.”
—Friedrich Nietzsche (18441900)
“Long before I wrote stories, I listened for stories. Listening for them is something more acute than listening to them. I suppose its an early form of participation in what goes on. Listening children know stories are there. When their elders sit and begin, children are just waiting and hoping for one to come out, like a mouse from its hole.”
—Eudora Welty (b. 1909)
