Introduction: The aim is to examine skin blood flow in diabetic patients having disease-related skin lesions, and to evaluate possible improvement imposed by low-intensity laser therapy (LILT) as a new treatment modality.

Methodology: Thirty patients (plus 15 controls receiving conventional treatment = Group II and 15 others receiving no treatment group = III) having diabetes-related skin lesions were tested for skin blood flow by laser Doppler Flowmetry. Group I patients received combined uniform He-Ne and infrared laser delivered by a scanner over the affected area by a specified dosimetry. A paired t test was used to determine the significance of blood flow recovery after treatment within each group, while Independent t test compared results between the 3 groups. The level of significance was at p < 0.05.

Results: The most frequently detected diabetes specific skin lesions were dryness, nail changes, hair loss, infections, itching, and frank eczema-like reactions, mostly in combinations (76%). This pattern appears specific for Egyptians as it is different from data registered in foreign literature. The minimum perfusion flow improved from 16.45 blood perfusion units before LILT to 25.94 after, while maximum flow recovered from 32.91 to 48.47 and basal perfusion changed from 24.68 to 34.84. The percentage change in perfusion values was 23.17. All these were statistically significant.

Conclusion: The study demonstrates that diabetes-linked skin lesions have a special pattern in Egyptians and are apparently caused by deranged skin blood flow. The deficit is measurable by laser flowmetry and can be partially reversed by LILT.
