Phototherapy (LEDs 660/890nm) in the treatment of leg ulcers in diabetic patients: case study. An. Bras. Dermatol. [online]. 2009, vol.84, n.3, pp.279-283.

This study evaluated the use of phototherapy in the healing of mixed leg ulcers in two diabetic patients (type 2) with arterial hypertension. The device had probe 1 (one 660nm LED, 5mW) applied in 3 ulcers and probe 2 (32 890nm LEDs associated with 4 660nm LEDs, 500mW) in 6 ulcers. After asepsis, ulcers were treated with probes to 3 J/cm2, 30sec per point, twice a week, followed by topical daily dressing with 1% silver sulphadiazine during 12 weeks. The following analyses of ulcers with software Image J showed that probe 2 presented mean healing rates of 0.6; 0.7 and 0.9, whereas probe 1 had 0.2;0.4 and 0.6 at 30, 60 and 90 days, espectively. Phototherapy accelerated wound healing of leg ulcers in diabetic patients.
