The Effect of Combined Red and Infrared Lasers on Histopathology Collagen Formation in Diabetic Foot Ulcer

Objective: investigate The effect of combined red and infrared lasers on histopathology collagen formation in diabetic foot ulcer Participants: The forty five patients will assigned randomly into three equal groups, each group consist of 15 patients, group A received laser therapy in sequential mode, group B received laser therapy in separate mode and the control group C receive conventional wound care treatment

Inclusion Criteria:aged between 18 and 60 years; both gender; Diabetic patients type II; Ulcer lasting longer than two months; diabetic foot ulcer (DFU) grade 1 (Superficial diabetic ulcer, ulcer limited to the dermis, not extending to the subcutis) or grade 2 (Ulcer of the skin extending through the subcutis with exposed tendon or bone and without osteomyelitis or abscess formation) according to the Wagner classificationExclusion Criteria:Patients with fixed ankle deformity as Charcot foot or stiffness; Patients with any type of osteomyelitis associated with DFU; the presence of active infection requiring hospitalization, gangrene, systemic diseases such as collagen-vascular diseases, renal failure, evidence of ischemia; BMI < 30 kg/m2 as Obesity can cause poor perfusion due to vascular insufficiencies; an altered population of immune mediators may lengthen the inflammatory process & decrease oxygenation of subcutaneous adipose tissue which is liable to be infected
