Skin blood flow in diabetic dermopathy.
BACKGROUND Diabetic dermopathy has been termed the most common cutaneous finding in diabetes, occurring in as many as 40% of diabetic patients older than 50 years. Using laser Doppler technology, we tested the hypothesis that dermopathy lesions represented areas of cutaneous ischemia. DESIGN A survey of cutaneous blood flow in diabetic patients with dermopathy and comparison of values with th...
متن کاملEarly decrease of skin blood flow in response to locally applied pressure in diabetic subjects.
Pressure ulcers are common debilitating complications of diabetes that are caused by tissue ischemia. Skin blood flow in response to locally applied pressure might be impaired in diabetic patients because of the combined effects of a typically low skin temperature and alterations in microcirculatory function, and could be worsened by neuropathy. We measured skin blood flow by laser Doppler flow...
متن کاملSweating and Skin Blood Flow in Women
Evaporation by sweating is the most effective way to remove heat from the body. Sweat rates increase under both local and whole-body heat stress. Men and women differ in how they respond to heat, because sexual steroids alter resting body core temperature and the threshold for sweating and skin blood flow (SBF) during heating. The purpose of the present study was to compare local sweat rates an...
متن کاملSkin capillary blood flow in scleroderma.
Skin blood flow was measured by the clearance of radioactive xenon ((133)Xe) injected intracutaneously in eight patients with scleroderma and nine control subjects under conditions of controlled temperature and humidity. Scleroderma patients, on being cooled 1 hr at 18 degrees C, had a rate constant of (133)Xe clearance from the dorsal finger skin which was 0.04 +/-0.07 min(-1) (mean +/-SD), co...
متن کاملBlood Flow in the Diabetic Leg
Femoropopliteal bypass grafting with reversed saphenous vein was performed in 47 nondiabetic and 27 diabetic extremities. Graft flow was measured with an electromagnetic flow probe before and after injection of 15 mg of papaverine into the graft. Basal flow (nondiabetic, 74 -+6; diabetic, 76 + 11 ml/min) was similar in the two groups. Peak flow was significantly higher in the nondiabetic group ...
