On Mon, 4 Mar 1996 Ruth Wilson <[log in to unmask]> posted: I believe a general review of Reynaud's syndrome is in order in light of the issue of "Medical shorthand", many folks lack info on this syndrome, anyone care to give it a try ? I'll try, Ruth... Raynaud's phenomenon, or syndrome, is a disorder of the blood vessels that supply the skin, consisting of vasospasm as arteries over-contract (hands, toes, other extremities turn white or "blanch" in response to cold or emotional stress or vibration, and become numb), followed a few minutes later by vasocongestion as arteries over-relax (same areas turn red, then purplish, and swollen as blood flow returns to area). There is no pain with the vasospasm but vasodilation or vasocongestion can be hot, burning, and uncomfortable. It occurs more commonly in women, and the cause is unknown, but the triggers are usually exposure to cold, frostbite, emotional stress, or continual vibration (typists, for example). Its a temporary occurrence that lasts just a few minutes in most cases. Prevention would include staying warm, wearing gloves to handle frozen foods, and treatment can include biofeedback, relaxation, and sometimes medication. Raynaud's can be primary or secondary: primary meaning it just happens on its own, secondary meaning it occurs and is associated with the development of other more serious diseases such as lupus, scleroderma, rheumatoid arthritis, use of various drugs, or seen in smokers. Women who experience Raynaud's should be screened for other more serious underlying diseases such as lupus or scleroderma, since it can be the initial symptom that presents. Fortunately, for most, I believe Raynaud's more often stands as an independent symptom, unrelated to the more serious diseases. I hope that helps clarify.
