Description and Extensions

Description: NCI2016_NICHD_1602D:An episodic vasoconstriction resulting in discoloration of the skin and pain in the affected areas, often involving fingers or toes. Classically associated with triphasic color changes (white, blue, red) but may be biphasic. Often occurs in response to cold temperatures or emotional stress. May be primary or secondary to an underlying autoimmune disease.|NCI2016_FDA_1602D:Intermittent bilateral attacks of ischemia of the fingers or toes and sometimes of the ears or nose, marked by severe pallor, and often accompanied by paresthesia and pain.|NCI2016_02D:An episodic vasoconstriction resulting in discoloration of the skin and pain in the affected areas, often involving fingers or toes. Classically associated with triphasic color changes (white, blue, red) but may be biphasic. Often occurs in response to cold temperatures or emotional stress. May be primary or secondary to an underlying autoimmune disease.|AIR93:WHAT: Raynaud's phenomenon. Raynaud's Phenomenon: the paroxysmal constriction of the small arteries and arterioles of the hands or feet, usually precipitated by cold or emotional upset, resulting in pallor and cyanosis of the fingers or toes following a characteristic pattern. WHY: Raynaud's phenomenon may occur in mixed connective tissue disease, systemic lupus erythematosus, progressive systemic sclerosis, poly- myositis/dermatomyositis, and rheumatoid arthritis associated with Sjogren's syndrome. HOW: In Raynaud's phenomenon there are three classic color changes of the fingers or toes. First, vasoconstriction results in a white blanching of the fingertips. Second, vasodilatation with sludging of vascular flow follows and results in blue, cyanotic digits. Finally, with recovery, there is increased blood flow with resulting erythema of the fingers. With observation of two of the three color changes, Raynaud's phenomenon is considered present. Local body cooling (by placing the hands in ice cold water) may demonstrate Raynaud's phenomenon, but some cases require general body cooling before the characteristic color phases occur. Permanent tissue damage can be induced by this testing, which therefore must be done only when absolutely necessary. If the digits show persistent cyanosis or there is evidence of pre-existing necrosis, performing this test is especially hazardous. One or more digits may be involved in Raynaud's phenomenon, and this involvement may be unilateral. REFS: 1) Spittell, JA: "Raynaud's phenomenon and allied vasospastic disorders".
