Randomized Controlled Trial Multicenter Study Comparative Study
Efficacy of intralesional recombinant human epidermal growth factor in diabetic foot ulcers in Mexican patients: a randomized double-blinded controlled trial.
The healing process in diabetic foot ulcer (DFU) is hindered by factors such as chronic inflammation, defects in fibroblast function, poor angiogenesis, and lack of cell migration. Recombinant human epidermal growth factor (rhEGF) has been shown to enhance extracellular matrix formation, cellular proliferation, and angiogenesis. Therefore, intralesional application of rhEGF in DFU could accelerate wound healing. ⋯ Mild transitory dizziness was the only side effect that was more frequently noted in the rhEGF group. Our results showed that in patients with DFU who received standard care, intralesional rhEGF application resulted in complete healing in more patients, promoted the epithelialization of the wound bed, and significantly reduced the area of the DFU treated. Therefore, rhEGF resulted in better outcomes for patients suffering from DFU.

Randomized Controlled Trial Multicenter Study Comparative Study
A randomized controlled trial of larval therapy for the debridement of leg ulcers: results of a multicenter, randomized, controlled, open, observer blind, parallel group study.
It has been known for centuries that the application of larvae is useful to heal certain wounds by facilitating debridement of necrotic tissue,(1) yet the efficacy of larval therapy continues to be debatable. This study compared the clinical effectiveness of a larval therapy dressing (BioFOAM) with a standard debridement technique (Purilon gel; hydrogel) in terms of time to debridement of venous (VLU) or mixed arterial/venous (MLU) leg ulcers. Data analyses were conducted on 88 subjects. ⋯ There were no statistically significant differences in the clinical condition of the wound bed and surrounding skin by intervention. Subjects in the larvae arm experienced more ulcer-related pain or discomfort than subjects in the hydrogel arm (p < 0.001). This study provided good evidence to show that larval therapy, in the form of a BioFOAM dressing, debrided VLU and MLU considerably more quickly than a hydrogel, although the possibility of resloughing should be closely monitored.

Randomized Controlled Trial Multicenter Study
Clinical effectiveness of dermal substitution in burns by topical negative pressure: a multicenter randomized controlled trial.
Previous research has shown clinical effectiveness of dermal substitution; however, in burn wounds, only limited effect has been shown. A problem in burn wounds is the reduced take of the autograft, when the substitute and graft are applied in one procedure. Recently, application of topical negative pressure (TNP) was shown to improve graft take. ⋯ Significantly fewer wounds in the TNP group showed postoperative contamination, compared to other groups. Highest elasticity was measured in scars treated with the substitute and TNP, which was significantly better compared to scars treated with the substitute alone. Concluding, this randomized controlled trial shows the effectiveness of dermal substitution combined with TNP in burns, based on extensive wound and scar measurements.

Randomized Controlled Trial Multicenter Study
A multicenter clinical trial of recombinant human GM-CSF hydrogel for the treatment of deep second-degree burns.
Wound healing is a complex and dynamic biological process. The efficacy and safety of a recombinant human granulocyte-macrophage colony-stimulating factor (rhGM-CSF) hydrogel to promote deep-second-degree burn wound healing is evaluated in this study. In this multicenter, randomized, double-blind, and placebo-controlled clinical trial, 90 patients with deep second-degree burns were randomly assigned into two groups. ⋯ A statistically significant difference was noted at each time point (p<0.01). No side effects were observed. These results suggest that rhGM-CSF hydrogel can significantly accelerate deep second-degree burn wound healing and is considered to be safe.

Randomized Controlled Trial Multicenter Study Comparative Study
Reducing wound pain in venous leg ulcers with Biatain Ibu: a randomized, controlled double-blind clinical investigation on the performance and safety.
Six out of 10 patients with chronic wounds suffer from persistent wound pain. A multinational and multicenter randomized double-blind clinical investigation of 122 patients compared two moist wound healing dressings: a nonadhesive foam dressing with ibuprofen (62 patients randomized to Biatain Ibu Nonadhesive Coloplast A/S) and a nonadhesive foam without ibuprofen (60 patients to Biatain Non-Adhesive-comparator). Patients were recruited from September 2005 to April 2006. ⋯ It was generally found that women reported less pain intensity than men, and pain intensity decreased with increasing age. In addition, pain intensity increased with initial pain intensity and increasing wound size. This study has demonstrated that the ibuprofen-foam dressing provided pain relief and reduced pain intensity without compromising healing or other safety parameters.
