| scalded skin syndrome | <syndrome> A potentially serious side effect of infection with the staph (staphylococcus) bacteria that produces a specific protein which loosens the cement holding the various layers of the skin together. This allows blister formation and sloughing of the top layer of skin. If it occurs over large body regions it can be deadly (just like a large surface area of the body having been burned). It is necessary to treat scalded skin syndrome with intravenous antibiotics and to protect the skin from allowing dehydration to occur if large areas peel off. The disease occurs predominantly in children under 5 years of age. It is known formally as staphyloccoccal scalded skin syndrome and as ritter disease. (12 Dec 1998) |

It often consists of an outer (epidermal) layer of silicone and an inner (dermal) layer of collagen and chondroitin 6-sulfate.

| skin botflies | A large, blue, brown-winged species whose larvae develop in open boil-like lesions in the skin of humans, many domestic animals, and some fowl. It is a very serious and damaging cattle parasite and frequently attacks small children in Central and South America. Its eggs are laid on the legs or abdomen of another insect, such as the mosquito; the eggs later hatch, when stimulated by warmth or other factors, to release the botfly larvae on the skin of the mosquito's bloodmeal host, and the larvae quickly invade the skin to initiate myiasis. Synonym: Dermatobia cyaniventris, human botfly, skin botflies, warble botfly. (05 Mar 2000) |
