“…The capillaroscopic exam should be done after a 15-min stay in a room at 19–23°C. This technique is used in the diagnosis of connective tissue disease, Raynaud's phenomenon, vasculitis, Adamantiades-Behçet disease ( Bergamo ), diabetic microangiopathy, and red fingers' syndrome ( 4 ) but also in other conditions such as venous insufficiency and venous ulcers ( Carpentier et al ) and psoriasis ( 5 ), in which the capillaroscopic examination is carried out above all the levels of the skin lesions under investigation (skin districts where the capillaries are vertical).…”
