Partial Thickness Burns

Skin thermal burn wounds are classified according to subjective assessments of wound depth that indicate divergent modes of medical intervention. However, clinically discriminating superficial partial from deep partial thickness burns remains a significant challenge, where only the latter requires excision and skin grafting. Motivated by the need for and ramifications of an objective burn wound assessment tool, this paper advances hyperspectral imaging (HSI) in a porcine skin burn model to quantitatively evaluate thermal burn injuries (superficial and deep partial thickness burns). Two-dimensional (2D) principal component analysis for noise reduction is applied to images captured by HSI in the visible wavelength range. Herein, a multivariate regression analysis is used to calculate the total hemoglobin concentration (tHb) and the oxygen saturation (StO2) of the injured tissue. These perfusion profiles are spatially mapped to yield characteristic distributions corresponding to the burn wound degree validated histologically. The results demonstrate that StO2 and tHb diverge significantly for superficial partial and deep partial burns at 24 h and 1 h, respectively (p < 0.05). A StO2 burn map at 1 h post-burn yields a 2D burn contour that is registered with a burn color image. This early stage burn-specific contour has implications to guide downstream burn excision and grafting.

Skin thermal burn wounds are classified by depth and require different levels of medical intervention. In this paper, the authors propose a novel treatment method where hyperspectral imaging (HSI) is applied to measure skin burn wound information that guide an additive biomanufacturing process to print a custom engineered skin graft in three dimensions (3D). Two dimensional principle component analysis (2DPCA) for noise reduction is applied to images captured by HSI in the visible wavelength range from 375 nm to 750 nm. A multivariate regression analysis is used to calculate hemodynamic biomarkers of skin burns, specifically the total hemoglobin concentration (tHb) and oxygen saturation (StO2) of the injured tissue. The biomarker results of the skin burn images are mapped spatially to show the burn wound depth distribution. Based on the biomarker values, the burn area is segmented into different sub areas with different burn degrees. Depth profiles of deep burns which require skin grafting are extracted from the burn distribution map. Next, each profile is processed to generate an additive biomanufacturing toolpath with a prescribed internal tissue scaffold structure. Using the toolpath, a 3D printer processes a custom graft from an alginate polymer hydrogel material. Alginate is chosen as the print material since it can be stretched into aligned fibers to create a porous structure that facilitates oxygen and nutrient uptake. The resultant printed construct demonstrates the feasibility of fabricating patient-specific tissues with custom-geometry grafts for treating clinical burns.

Abstract Objective Burn wound progression is an inflammation driven process where an initial partial-thickness thermal burn wound can evolve over time to a full-thickness injury. We have developed an oil-in-water nanoemulsion formulation (NB-201) containing benzalkonium chloride for use in burn wounds that is antimicrobial and potentially inhibits burn wound progression. We used a porcine burn injury model to evaluate the effect of topical nanoemulsion treatment on burn wound conversion and healing. Methods Anesthetized swine received thermal burn wounds using a 25cm 2 surface area copper bar heated to 80 oC. Three different concentrations of NB-201 (10%, 20%, or 40% nanoemulsion), silver sulfadiazine cream or saline were applied to burned skin immediately after injury and on days 1, 2, 4, 7, 10, 14, and 18 post-injury. Digital images and skin biopsies were taken at each dressing change. Skin biopsy samples were stained for histological evaluation and graded. Skin tissue samples were also assayed for mediators of inflammation. Results Dermal treatment with NB-201 diminished thermal burn wound conversion to a full-thickness injury as determined by both histological and visual evaluation. Comparison of epithelial restoration on day 21 showed that 77.8% of the nanoemulsion treated wounds had an epidermal injury score of 0 compared to 16.7% of the silver sulfadiazine treated burns (p=0.01). Silver sulfadiazine cream and saline treated wounds (controls) converted to full-thickness burns by day 4. Histological evaluation revealed reduced inflammation and evidence of skin injury in NB-201 treated sites compared to control wounds. The nanoemulsion treated wounds often healed with complete regrowth of epithelium and no loss of hair follicles (NB-201: 4.8±2.1, saline: 0±0, silver sulfadiazine: 0±0 hair follicles per 4mm biopsy section, p&lt;0.05). Production of inflammatory mediators and sequestration of neutrophils were also inhibited by NB-201. Conclusions Topically applied NB-201 prevented the progression of a partial-thickness burn wound to full-thickness injury and was associated with a concurrent decrease in dermal inflammation.

Abstract Backgroud: Burns wound treatment remains a significant clinical challenge around the world. Although stem cell-based scaffold therapies are promising strategy for burn wounds, its clinical therapeutic effect is still not satisfactory nowadays. Herein the aim of this study is to evaluate the therapeutic efficacy of injectable small intestinal submucosa (SIS) and rat adipose-derived mesenchymal stem cells (ADSCs) composite gel to repair the deep partial thickness burns in rats. Methods The deep partial-thickness burns model in rats were made by contacting the dorsal surface SIS memberance directly with boiled water for 10 seconds. After scalding, the wound edge and the central area were injected for phosphate-buffered saline (PBS) solution, ADSCs, injectable SIS and injectable SIS/ ADSCs composite gel, respectively. At 3, 7, 14 and 21 days post injection treatment, the burn wound closure percentages were evaluated. Moreover, micro-vascular density and epidermal thickness assessment in burn wound were performed by histopathology examination or immunofluorescence. Besides, the expression of genes related to wound angiogenesis and re-epithelialization were determined in vitro. Results Our data revealed that that injectable SIS gel could provide a well-grown microenvironment for ADSCs in vitro, and the ADSCs-SIS composite gel could synergistically promote the deep partial-thickness burn repair via paracrine and differentiation mechanisms. Conclusions Taken together, this study shows the ADSCs-SIS composite gel is a promising candidate for burn wound regeneration.

Background Dermal burns (partial thickness burns) are the most painful trauma with two types of pain background pain with additional procedural pain, one of the best tolerable mode of treatment that commonly used now adays is treatment with MEBT ointments to maintain the moist and warm wound environment suitable for regeneration of epidermal cells, and to reduces pain. Moist wound dressings retain moisture, heat, body fluids, and biofilm with medication. The assumption is that the polyethylene film will maintain the ointment and its effect more than to be used merely. Patients and methods Prospective study to evaluate treatment of patients with partial thickness burns conservatively with MEBT ointment as a control group and MEBT ointment + Cling Film, 63 patients being admitted to the burn center at Azadi teaching hospital during a period of one year starting from June 2018 till June 2019. The inclusion criteria including all patients between 10-95% partial thickness burns of various age, sex and skin types. Results Very much decrease in procedural and background pain, better joint movement in physiotherapy decrease in crust formation, increase maceration of eschar, better cost- effectiveness, less days of hospital stay. Aim; in Iraq circumstances we have to use the most cost effective measures to reach our goals in managing the burn wounds the moist trend which is now being proved it gives better healing with less pain, with best criteria of wound dressing . Conclusion Easily applicable, less painful, non-coasty over all, better condition of patient during course of management, reduced length of hospital stay and lower treatment costs, appropriate wound healing with living tissue , less joint stiffness problems

Abstract This study aims to evaluate the efficacy of Nile tilapia skin as a xenograft for the treatment of partial-thickness burn wounds in children. This is an open-label, monocentric, randomized phase II pilot study conducted in Fortaleza, Brazil. The study population consisted of 30 children between the ages of 2 and 12 years with superficial “partial-thickness” burns admitted less than 72 hours from the thermal injury. In the test group, the tilapia skin was applied. In the control group, a thin layer of silver sulfadiazine cream 1% was applied. Tilapia skin showed good adherence to the wound bed, reducing the number of dressing changes required, the amount of anesthetics used, and providing benefits for the patients and also for healthcare professionals, by reducing the overall work load. The number of days to complete burn wound healing, the total amount of analgesics required throughout the treatment, burn improvement on the day of dressing removal, and pain throughout the treatment were similar to the conventional treatment with silver sulfadiazine. Thus, tilapia skin can be considered an effective and low-cost extra resource in the therapeutic arsenal of pediatric superficial partial thickness burns.
