Abstract
Leprosy is disease of skin and peripheral nerve especially. Sequale and disability of musculoskeletal system, especially peripheral extremities (hands and foots) can be developed due to severe and irreversible peripheral nerve damage in leprosy. In leprosy, Skin ulcers can relapse very often and progress to deformity and amputation of hands or foot. We needto treat skin ulcer effectively. We have usedvarious therapies such as antibiotics in infectiosstate, disinfectant, variable wet dressing(transparent film, foams, gels&hydrogels, hydrocolloids, calciumalignate), silver dressing,Vacuum Assisted Closure, debridement, curettage, surgeryetcto treat skin ulcer in old leprosy patients.
Sometimes we can treat skin ulcer successfully but, we often encounter ulcer resistant to treat. We need to find and develop methods to treat ulcer successfully. Several researches have reported articles to treat wound using light emitting diode(LED). We tried to treat ulcer in old leprosy patients using LED. We divided ulcers patients into case group (conventional dressing + LED therapy) and control group(only conventional dressing therapy) randomly in out patient department and in ward. This research was carried out from February 2012 to September 2012. Case group and control group have composed of 30 patients respectively. Average age of patients was 74 in case group and 69 in control group. We have used LED device composed of 700 diodes emitting 635nm and 500 diodes emitting 830nm, totally 1200 diodes. We have observed the size of wounds twice per week in control group and case group. Before treatment average size of wounds was 8509.76 in case group and 8625.33 in control group. P-vale was 0.49.There was no significant difference in case and control group. After treatment average size of wounds was 787.83 in case group and 8074.63 in control group. P-vale was 0.02. There was significant difference in case and control group. After treatment average reduction of size per time was 338.02 in case group and 26.55 in control group. P-vale was 0.002. There was significant difference in case and control group. Therefore we have concluded that LED device was effective in wound treatment. Some articles have reported that LED Device have help treat wounds in DM ulcer, 3nd degree burn, oralulcer, skin ulcer in Klippel-Trenaunaysyndrome patient, some retinopathy etc. We can use LED device(infrared or long wavelength visible ray) in treatment of wound suplementarily with conventional treatment concurrently.
