Joint Range of Motion in Burn Scars
Contractures Resulting From Burn Scar TissueThe purpose of this study is to determine the relationship between cutaneous functional unit(CFU)recruitment throughout the available active range of motion of a prescribed joint in normal subjects and patients with burn scars. Specifically, this study will determine if differences in CFU recruitment exist between normal subjects and individuals with burn scars at the dorsal hand, dorsal or volar forearm, or anterior or posterior arm during active range of motion of the MCP joint during flexion, or the wrist or elbow during flexion or extension, respectively.

Testing an Innovative Biomarker: Expression of HIF-1α and Its Isoforms in the Blood and Skin Tissue...
Burn InjuriesBurn injury with full-thickness skin damage that encompass large body surface areas can induce local and systemic perturbations that are costly in terms of human suffering as well as in strains on the health care system. Characterization of new major molecular biomarkers involved in this process creates significant diagnostic and therapeutic challenges. Hypoxia-inducible factor-1 α (HIF-1 α) is a ubiquitously expressed heterodimeric transcription factor comprising an α and a β subunit. It was shown that under normoxic conditions, the HIF-1α subunit is ubiquitinated and degraded, whereas under hypoxic conditions, HIF-1α accumulates, dimerizes with HIF-1β, and activates the transcription of a spectrum of target genes encoding multiple angiogenic growth factors and cytokines of potential importance in wound healing. Seven isoforms of HIF-1α issued from alternative splicing have been identified. The importance of HIF-1α in wound healing in animal models has been suggested by several studies. Indeed, diminished HIF-1 levels and activity have been documented in conditions of impaired wound healing. The literature review shows a marked reduction of HIF-1α levels in mice in case of burn wound skin that in the case of excisional cutaneous wound. Other studies have shown that the expression of HIF-1α was correlated with the extent and depth of the burns. This study aims to improve the knowledge on the pathophysiological factors involved in the field of wound healing. The assumptions are based on results of studies done on mice, and this work aims to document these findings in humans. Objective The main objective of the study is to compare the variations of expression of HIF-1α measured in blood and skin tissue samples in three groups: Subjects with major burn wounds involving more than 20% of the total body surface area; Subjects with burn wounds smaller than 5% of total body surface area; Subjects with a skin wound after a surgical procedure requiring a skin resection. Secondary objectives are to compare the expression levels of HIF-1α locally at the burn site to those observed in blood, to evaluate the expression of growth factors produced by HIF-1α target genes (VEGF and EPO) or playing a central role in the healing process (TGF-β1), and to assess the correlation between the expression of HIF-1α and the kinetics of wound healing of the subject rated by evaluation of time of donor sites complete epithelialization. Material and Methods We propose to create three groups: 15 patients with extensive third degree burns involving more than 20% of the total body surface area; 15 patients with less extensive third degree burns, involving less than 5% of body surface area; 15 patients with post-surgical wounds with skin resection. Skin and tissue specimens will be collected three times: day 0, 7 and 14 from burned patients (with more than 20% of the total body surface area and less than 5% of body surface area). Samples of skin tissue will be collected within the skin resection from patients with post-surgical wounds at day 0, blood samples will be collected at day 0 and 14.
Fractional Nonablative 1540 nm Laser Resurfacing for Burn Scars- A Randomised Controlled Trial

Safety Study of a Novel Wearable Phototherapy System for the Management of Acute Burn Wounds
Burn WoundThe primary purpose of this first-in-human, early feasibility study is to assess safety and feasibility of the Low-Irradiance Monochromatic Biostimulation (LIMB) System as a phototherapeutic intervention for the management of acute burn wounds. The prototype LIMB device will be evaluated for the occurrence of adverse events (treatment-related or otherwise) of the LIMB System, a portable, wearable, light-emitting system developed by Rogers Sciences, Inc. (RSI). The device will be administered in the small feasibility pilot to confirm design, usability and operating specifications that will inform procedures and endpoints of a subsequent large, multicenter clinical trial.
Assessing Bioavailability of CoQ10 Supplementation in Burn Patients
Burn InjuryTo test the hypotheses that plasma and intracellular coenzyme Q10 levels will decline after burn injury and that ubiquinol supplementation will increase plasma and intracellular coenzyme Q10 levels in burn patients. To test the hypothesis that ubiquinol supplementation ameliorates mitochondrial dysfunction/disintegrity and metabolic derangements, and decreases circulating alarmins (a.k.a. endogenous DAMPs) in burn patients as compared with placebo.
