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

Study Overview
=================
Brief Summary
-----------------
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

Eligibility Criteria
-----------------
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 classification Exclusion 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

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: laser sequential mode<br>All patients received 2 sessions of laser therapy / week with different wavelengths in sequential mode in two consecutive months of treatment aiming complete wound closure , patients received & infrared laser therapy plus traditional wound care | Device: laser therapy<br>* All patients received 2 sessions of laser therapy / week in two consecutive months of treatment aiming complete wound closure , patients received & infrared laser therapy plus traditional wound care: (I) Use red & infrared laser therapy device with 4 different wavelengths in a synchronized mode: 980 nm for wound decontamination, improve circulation, lymphatic drainage 915 nm enhances O2 delivery 810 nm increases ATP production 650 nm accelerate surface healing, tissue regeneration plus traditional wound treatment mentioned before<br>|
| Experimental: laser seperate mode<br>All patients received 2 sessions of laser therapy / week with different wavelengths in seperate mode in two consecutive months of treatment aiming complete wound closure , patients received & infrared laser therapy plus traditional wound care | Device: laser therapy<br>* All patients received 2 sessions of laser therapy / week in two consecutive months of treatment aiming complete wound closure , patients received & infrared laser therapy plus traditional wound care: (I) Use red & infrared laser therapy device with 4 different wavelengths in a synchronized mode: 980 nm for wound decontamination, improve circulation, lymphatic drainage 915 nm enhances O2 delivery 810 nm increases ATP production 650 nm accelerate surface healing, tissue regeneration plus traditional wound treatment mentioned before<br>|
| Active Comparator: traditional wound care<br>Traditional wound care inform of Wound care treatment Debridement to remove necrotic tissue Irrigation of the wound by normal saline Change dressing daily to protect wound from infection Foot care Wash feet daily, dry carefully especially between toe Avoid extreme temperatures Inspection daily of foot blisters Foot wear Avoid walking bare foot Properly fitted shoes Avoid wearing open-toed shoes | Device: laser therapy<br>* All patients received 2 sessions of laser therapy / week in two consecutive months of treatment aiming complete wound closure , patients received & infrared laser therapy plus traditional wound care: (I) Use red & infrared laser therapy device with 4 different wavelengths in a synchronized mode: 980 nm for wound decontamination, improve circulation, lymphatic drainage 915 nm enhances O2 delivery 810 nm increases ATP production 650 nm accelerate surface healing, tissue regeneration plus traditional wound treatment mentioned before<br>|
