New antioxidant therapy for hard-to-heal neuroischaemic diabetic foot ulcers with deep exposure.

Objective: To evaluate the clinical efficacy of a new antioxidant therapy for the treatment of complex neuroischaemic diabetic foot ulcers (DFUs).

Method: A prospective case series study has been conducted in patients with complex neuroischaemic DFUs after transmetatarsal amputation. DFUs were locally treated with an antioxidant dressing twice a week for the first two weeks, and then once a week until the end of the study or complete wound closure.

Wound Dressing Selection Is Critical to Enhance Platelet-Rich Fibrin Activities in Wound Care.

The use of platelet-rich fibrin (PRF) is investigated in ulcer management because it provides a healing milieu rich in growth factors and cytokines. Although crucial, the relevance of secondary dressings is under-researched and no data support the use of any particular dressing in preference to another. We assessed the properties of different dressing categories, including alginates, hydrocolloids, foams, hydrofibers, films, meshes and gauzes, in terms of affinity for PRF, releasate management (retention/extrusion) and the kinetics of cytokine release as well as the influence of each combination product, [PRF + dressing], on dermal cell behaviour, aiming to provide useful information for choosing the most adequate dressing for each particular patient.

Biological approach for the management of non-healing diabetic foot ulcers.

Objective: To show an approach to profit of the main components of platelet rich plasma (PRP), i.e. the signaling proteins, and the fibrin scaffold and discuss the intervention within TIME (Tissue, Inflammation/Infection, Moisture, Edges) framework.
