PHOTOTHERAPY IMPROVES HEALING OF CHRONIC VENOUS ULCERS

Abstract Objective: We tested the hypothesis that LED phototherapy

will promote healing of venous ulcers that failed to respond to other forms of

treatment. Background Data: A variety of dressings, growth factors, and adjunct therapies are used to treat venous ulcers, but none seems to yield satisfactory results.

Ulcers treated with phototherapy healed significantly faster than controls when compared at day 30 and day 90. Conclusion: Phototherapy promotes healing of chronic venous ulcers, particularly large recalcitrant ulcers that do not respond to conventional treatment.

DIABETIC NEUROPATHIC FOOT ULCER: SUCCESSFUL TREATMENT BY LLLT

Objective: To evaluate the efficacy of low-intensity laser irradiation for the induction of wound healing of a diabetic neuropathic foot ulcer. CASE: We report a case of a man with insulindependent diabetes mellitus, sensory neuropathy, macroangiopathy and microangiopathy who had been suffering from an ulcer of his first left toe accompanied by osteomyelitis for 6 weeks.

Results: After a total of 16 sessions of low-intensity laser administered within a 4-week period the ulcer healed completely. During a follow-up period of 9 months, there was no recurrence of the ulcer even though the patient’s metabolic condition remained unstable.

EFFECTS OF PHOTOTHERAPY ON PRESSURE ULCER HEALING IN ELDERLY PATIENTS AFTER FALLING TRAUMA.  A PROSPECTIVE, RANDOMIZED, CONTROLLED STUDY

PRESSURE ULCERS

Background: The effects of infrared and red pulsed monochromatic light, with varied pulsations and wavelengths, on the healing of pressure ulcers were evaluated in this prospective, randomized, controlled study.

Results: Patients treated with pulsed monochromatic light had a 49% higher ulcer healing rate, and a shorter time to ulcer closure compared with controls. Their mean ulcer area was reduced to 10% after 5 weeks compared with 9 weeks for the controls.

Conclusion: The results are encouraging as pulsed monochromatic light increased healing rate and shortened healing time. This will positively affect the quality of life in elderly patients with pressure ulcers.
