Wound healing is a well-coordinated sequence of events in which signalling and remodelling of the extracellular matrix (ECM) are integral components. dehydrated human amnion/chorion membrane (dHACM) has demonstrated clinical efficacy in the enhancement of wound repair compared with standard compression therapy.

Burns, trauma, chronic and complex wounds can result in complete loss of skin, leading to infection, increased insensible water loss, hypothermia, difficulties in patient management. Lenon Cardoso and Coll performed this study to assess the efficiency of a porous bioresorbable membrane Poly (L-co-DL lactic acid)-co-trimethylene carbonate, PL-co-DLA-co-TMC, as a dermal substitute associated with partial skin graft in rats.
The approach of regenerative medicine has emerged as an alternative to provide additional therapeutic options to potentially improve wound healing.
Human amniotic membranes (hAMs) have shown promising results in recent studies aimed at improving wound healing. Ben Samuel John and Coll conducted a study on the 2019 full-thickness skin defects in 4 groups of 6 rats with one wound each.
Walid Mari and Coll conducted a prospective, multicentered, randomized, controlled, single-blinded clinical trial from August 2014 to June 2016 about the use of negative pressure and natural porcine extracellular matrix in stage 4 pressure injuries.
A discussion about the use of dermal substitutes collagen made for the treatment of burn. Have a look of my contents in the Al Das Medical Clinic web site
Another scientific publication about a clinical case at Al Zahra Hospital Dubai, using Dehydrated human amnion/chorion membrane for the treatment of venous leg ulcers.
This is a clinical case using hADM to close an open wound of the right foot caused by the penetration of part of a shell into the skin followed by necrotizing fasciitis, after multiple unsuccessful treatments using Negative Pressure Wound Therapy, porcine acellular dermal substitutes and a split-thickness skin graft.
Hyaluronic acid is a natural polymer. In the human body, it is distributed around cells and in the extracellular matrix (ECM). A Fallacara and Coll conducted an interesting overview, describing the history, physicochemical, structural and hydrodynamic of hyaluronic acid. They evaluated also the different applications of the HA in medicine, pharmaceutical and cosmetic fields.
An interesting scientific publication by Dr. Tettelbach and Coll who conducted a prospective, randomized, controlled and multicentre clinical trial. The scope of this study was to evaluate the healing outcomes in diabetic patients with chronic lower extremity ulcers treated with a weekly application of dHACM.
