What is the classic triphasic presentation of Raynauds?
cold-induced pallor, then cyanosis, followed by hyperemia, but incomplete forms are frequent.
This progression is rarely seen in childhood.
Examination of the cuticle edge, using an otoscope or a special microscope called a capillaroscope, is important to screen for dilated and/or tortuous capillaries that may suggest an underlying rheumatic disease such as lupus or scleroderma.
How is Raynaud's treated?
Treatment involves education about keeping the extremities and core body warm and the role of stress, which may be a precipitant. In very symptomatic patients, treatment with calcium channel blockers such as nifedipine can be effective.
