Abstract Introduction Split-thickness skin grafting (STSG) is the standard of care for the treatment of full thickness skin injuries. Skin grafts are associated with long-term morbidity including graft loss, adjacent structural injury, anesthetic complications, scarring, and scar contractures. Large surface area burns are additionally challenging due to limited donor site availability. Autologous skin cell suspension (ASCS) is a new adjunct for STSG using device that provides a suspension of non-cultured, autologous skin cells applied overtop of STSG. Dermal matrix templates are placed on wounds after burn excision and induces dermal regeneration in preparation for STSG, allowing for a thinner graft to be harvested and applied. This technique has been shown to require both smaller areas of donor skin as well as thinner skin harvest which improves both healing time and aesthetic outcomes of donor sites, enhancing the time-tested and well accepted technique of STSG. Methods We present the case of a 5-year-old African American female who suffered 18% TBSA deep partial thickness burns and full thickness burns to her abdomen, trunk and left back after her shirt was accidentally lit on fire at home. She was transferred from a local hospital to our burn center for further evaluation. She was evaluated by both the burn surgery and pediatric teams and admitted for wound cares and surgical planning. Results On hospital day five she underwent burn excision and placement of acellular dermal regeneration template. She returned to the operating room on hospital day 22 after daily wound cares for autografting with autologous skin cell suspension application to anterior and posterior torso and left arm, as well as to back and thigh donor sites. Her takedown on hospital day 29 showed excellent graft take. She was ultimately discharged on hospital day 47. She continued to undergo wound care in the outpatient burn clinic and daily physical and occupational therapy. Conclusions This case illustrates the use of dermal matrix and ASCS on a large burn with excellent aesthetic outcomes and improved healing time. This case is unique in highlighting the versatility of this therapy in a darker skinned patient. There are significant challenges with long term morbidity from STSG and the use of both dermal regenerative matrix and ASCS may provide surgeons with new approaches to decreasing depth and size of donor sites, as well as improving the length of hospital stay and overall aesthetic outcomes of donor and graft sites, specifically in darker skinned patients.

Abstract Introduction Advances in burn injury knowledge, critical care, and pharmacological developments have increased survival rates among extensive burn patients. Survival now dependents not just on skin coverage, but effective control of SIRS response, metabolic derangement, fluid loss and sepsis. Novel synthetic dermal substitutes create robustness, thickness, and pliability of the skin in addition to an improved aesthetic appearance while; point-of-care autologous skin cell harvesting enhances treatment by amplifying small split-thickness skin samples to produce an autologous skin cell suspension (ASCS) to cover a larger burn area. This study reports on two survivors with greater than 90% total body surface area full-thickness burns utilizing a combined treatment of a dermal substitute along with ASCS and traditional burn management strategies. Methods Chart review of two patients with >90% burns and inhalation injury after being trapped in a burning vehicle following a traffic collision occurred. Most of the burns in both patients were “leathery” and consistent with full thickness, sparing only the plantar and dorsal aspect of the feet and bilateral small areas of the hip in Patient 1. Patient 2 had fourth-degree burns in some areas of the chest and flank with only the bilateral groin regions and feet spared. The patients were treated with a multi-step process which included using allograft, dermal substitute, and ASCS with split-thickness skin grafts (STSG) in place of cultured epidermal autograft to achieve coverage of >90% burns with high meshed ratio. Results The dermal substitute was limited to deep burns that penetrated down to fat, muscle, and/or joints. Fluid loss was well controlled by the dermal substitute during initial resuscitation. Post reconstruction, areas covered with the dermal substitute and grafted with autogenous STSG with ASCS exhibited less hypertrophy and contracture bands. The elbow and knee joints showed minimal restriction with passive motion and good skin compliance, but contractures persisted in areas where 4th degree tendon and fascia thermal injury occurred. Areas that showed signs of infection were trimmed or unroofed and allowed to drain while maintaining the remainder of the dermal substitute. Conclusions The use of dermal substitutes and ASCS allowed the care team to achieve SIRS control, improved fluid management, enhanced skin coverage, and reduced hospitalization stay. The process experienced in these cases shows promise for future patients with extensive burns. Both patients were able to survive and show improvement during rehabilitation.

AbstractBecause molecular memories of past inflammatory events can persist in epidermal cells, we evaluated the long-term epidermal protein expression landscapes after dermal regeneration and in psoriatic inflammation. We first characterized the effects of two dermal regeneration strategies on transplants of indicator split-thickness skin grafts (STSGs) in ten adult patients with deep burns covering more than 20% of their body surface area. After fascial excision, three adjacent areas within the wound were randomized to receive a permanent dermal matrix, a temporary granulation-tissue-inducing dressing or no dermal component as control. Control areas were covered with STSG immediately, and treated areas after two-weeks of dermis formation. Epidermis-dermis-targeted proteomics of one-year-follow-up samples were performed for protein expression profiling. Epidermal expression of axonemal dynein heavy chain 10 (DNAH10) was increased 20-fold in samples having had regenerating dermis vs control. Given the dermal inflammatory component found in our dermal regeneration samples as well as in early psoriatic lesions, we hypothesized that DNAH10 protein expression also would be affected in psoriatic skin samples. We discovered increased DNAH10 expression in inflammatory lesions when compared to unaffected skin. Our results associate DNAH10 expression with cell proliferation and inflammation as well as with the epidermal memory resulting from the previous regenerative signals of dermis. This study (ISRCTN14499986) was funded by the Finnish Ministry of Defense and by government subsidies for medical research.

Abstract Introduction An autologous skin cell suspension (ASCS) spray containing keratinocytes, fibroblasts, and melanocytes can be processed from a small split thickness skin sample for use at the point-of-care in the operating room. ASCS have been shown to facilitate epidermal regeneration in large TBSA partial thickness burns with minimal donor site morbidity. We hypothesized that ASCS in conjunction with a 3:1 split thickness skin graft applied to burn wounds and ASCS alone applied to the donor site would facilitate healing in a 95 year-old burn patient with 12% TBSA deep partial and full thickness scald burns to the abdomen and bilateral thighs. To our knowledge, she is the oldest patient to undergo epidermal autografting with ASCS. Methods All burn wounds were tangentially excised in the standard fashion to healthy tissue. Split thickness (12/1000 inch) skin graft was harvested from the right lateral thigh, meshed 3:1, and applied to all wound beds. ASCS were prepared and sprayed on grafted sites and the donor site. All areas were dressed with Telfa clear and Xeroform with bacitracin. Dressings were initially changed every 2 days, and wounds were photographed on day 2, 4, 6, 8, 10, and 20. Results All burn wounds were deep partial thickness or full thickness. The right thigh donor site was completely healed by POD 10. 90% of the burn wounds had healed by POD 10. The area of deepest burn, an approximately 20 cm2area on the left medial thigh, was healed by POD 20. Conclusions We believe that ASCS enhanced the rate of re-epithelialization of burn wounds in a 95 year-old patient compared to our experience with skin grafting alone in this population. ASCS also promoted complete healing of the donor site by POD 10. This technology may have a role in decreasing healing time in the geriatric burn population. These findings are important for this population as longer lengths of stay are associated with delirium, hospital acquired infections, and deconditioning. This patient’s improved donor site healing also has broader implications as split thickness skin grafts are used widely for wound coverage in plastic surgery. Applicability of Research to Practice Demonstrates efficacy of ASCS in very elderly patients with moderate-sized deep burns and with skin graft donor sites.

Abstract Dermal substitutes coupled with split thickness skin graft are the primary method of treating most severe full-thickness burns particularly when there is a lack of healthy donor skin. Although dermal replacements optimize functional and aesthetic outcomes in patients, the risk of infection and the amount of time required to process most dermal substitutes delay treatment potentially compromising graft take and the overall healing process. The purpose of this case series is to describe the treatment course of patients with severe burn injuries using a novel synthetic Biodegradable Temporizing Matrix (NovoSorb BTM) in conjunction with RECELL Autologous Cell Harvesting Device, a new methodology allowing for a timely point-of-care preparation of an autologous skin cell suspension in combination with a 3:1 split-thickness skin graft. To the best of our knowledge, this is the first reported case series to describe the treatment algorithm and clinical outcomes of deep full-thickness burns utilizing BTM in conjunction with RECELL ASCS.
