Raynaud's Disease and Raynaud's Syndrome: Characteristics, Causes and
Differences
------------------------------------------------------------------------------
QUESTION: I have a peculiar problem that causes my fingers to turn blue when
the temperature drops even a little bit or when I get upset. The doctor
called it Raynaud's Disease. I have tried to find out as much as I can about
my condition and have seen other words like "phenomenon" and "syndrome" linked
with the name. Are these all the same thing? Just what is Raynaud's Disease
and what treatments are available? Thanks for all your help.
------------------------------------------------------------------------------
ANSWER: The condition was first described by Maurice Raynaud in 1862, when he
noted three color changes that occur most commonly in fingers or toes, when a
spasm of the arteries shuts off the blood flow to the digits. First the color
is dead white, from lack of circulating blood, then turns blue, because of the
lack of oxygen (cyanosis), then becomes red (hyperemia) as a surge of blood
returns to the digits. Usually this is a benign condition that is seen more
frequently in women (about 9 to 1 over men), which begins during the 20's and
30's. When there is no detectable underlying reason for this, it is called
Raynaud's Disease. However, this same situation may be associated with many
other disorders, including connective tissue diseases (such as lupus or
scleroderma), vascular diseases (temporal arteritis for example), blood
disorders (polycythemia vera), neurologic disorders (causalgia, reflex
sympathetic dystrophy), after trauma caused by cold (frostbite) or vibration
(as in jackhammer operators).
In some cases, where there is a possibility of an underlying illness that
still remains unproven, it may be referred to as Raynaud's "syndrome". While
there is no specific cure, an number of possible treatment strategies can
reduce the symptoms. Avoiding stress, cold, tobacco and caffeine may be
sufficient to control symptoms. Behavioral modification techniques and
biofeedback training are useful, and if these are inadequate, medications
including calcium channel blockers or nitrates may be prescribed.
