The majority of full-thickness burn wounds heal with hypertrophic scar formation. Burn eschar most probably influences early burn wound healing, since granulation tissue only forms after escharotomy. In order to investigate the effect of burn eschar on delayed granulation tissue formation, burn wound extract (BWE) was isolated from the interface between non-viable eschar and viable tissue. The influence of BWE on the activity of endothelial cells derived from dermis and adipose tissue, dermal fibroblasts and adipose tissue-derived mesenchymal stromal cells (ASC) was determined...

Burns are a very painful skin injury, or injury of soft tissues. The development of post-traumatic stress disorder can develop, even in those with minor injuries (Ia-IIb degree). Development of problems is very rapid and intense since, according to developmental embryology, the skin and central nervous system (CNS) descend from the same germ layer-ectoderm. This clinical report presents the results acquired from the data of 1008 patients suffering from burns treated by the acupuncture (ACU)-from 1983-2015 in the surgery ward of the hospital in Vysoke Myto in the Czech Republic...

BACKGROUND: Pseudomonas aeruginosa is an opportunistic pathogen with the ability to cause severe nosocomial infections and remains a major problem in burn patients. This organism shows a remarkable antimicrobial resistance and is often resistant to multiple antibiotics. Integron genes as mobile genetic elements are playing an important role in the spread of P. aeruginosa antibiotic resistance. This study was aimed to investigate the occurrence of class 1, and 2 integron genes (int1, int2), among P...

Artificial skin has achieved considerable therapeutic results in clinical practice. However, artificial skin treatments for wounds in diabetic patients with impeded blood flow or with large wounds might be prolonged. Cell-based therapies have appeared as a new technique for the treatment of diabetic ulcers, and cell-sheet engineering has improved the efficacy of cell transplantation. A number of reports have suggested that adipose-derived stem cells (ASCs), a type of mesenchymal stromal cell (MSC), exhibit therapeutic potential due to their relative abundance in adipose tissue and their accessibility for collection when compared to MSCs from other tissues...

Although the wound healing effects of nitric oxide (NO) are known, the mechanism by which NO modulates corneal wound healing remains unclear. In this study, we investigated the effect of exogenous NO donor (NaNO2) on corneal wound healing. We found that NaNO2 (0.1 μM to 100 μM) increased human corneal epithelial cell (HCEC) viability and migration. It also modulated the phosphorylation of mitogen-activated protein kinases (MAPKs) in a time- dependent manner in those HCECs. Further, p38 MAPK phosphorylation increased at 6 h and normalized at 24 h, while the phosphorylation of extracellular signal regulated kinase (ERK) was increased both at 6 h and 24 h...

BACKGROUND: There exists neither a consensus definition of burn "graft loss" nor a scale with which to grade severity. We introduced an institutional scale in 2014 for quality improvement. MATERIALS AND METHODS: We reviewed all burned patients with graft loss on departmental Morbidity and Mortality reports between July 2014 and July 2016. Graft loss grades were assigned during the course of clinical care per institutional scale. Chronic nonhealing wounds and nonburn wounds were excluded...

'Fragile skin', or skin with lower resistance to aggressors, can be broadly classified into four causal categories: constitutional (age-dependent or associated with specific vulnerable locations on the body, e.g. eyelids), pathological (related to disease), circumstantial (related to environmental or internal factors, e.g. stress) and iatrogenic (caused by medical interventions or treatments). In this supplement, we focus on the fourth category, the iatrogenic origin of fragile skin and the role that dermo-cosmetics can have in restoring the natural protective function of the skin following treatments for skin diseases and medical interventions...

INTRODUCTION: There is significant nationwide interest in transitioning new and new-to-specialty nurses into practice, especially in burn care. Lack of a structured transition program in our Burn Center was recognized as a contributing factor for nursing dissatisfaction and increased turnover compared to other hospital units. Employee evaluations exposed a need for more didactic instruction, hands-on learning, and preceptor support. The goal of this project was to implement an evidence-based transition to practice program specific to the burn specialty...

Management of severe burn injury (SBI) requires prompt, complex, and aggressive care. Despite major advances in the management of SBI-including patient-targeted resuscitation, management of inhalation injuries, specific nutritional support, enhanced wound therapy, and infection control-the consequences of SBI often result in complex, multiorgan metabolic changes. Consensus guidelines and clinical evidence regarding specific management of small animal burn patients are lacking. This article aims to review updated therapeutic consideration for the systemic and local management of SBI that are proven effective to optimize outcomes in human burn patients and may translate to small animal patients...

INTRODUCTION: New technologies in the field of burn wound and scar assessment are continually being evaluated. Accurate estimation of total body surface area (TBSA) burn wound is of paramount importance in fluid resuscitation to prevent complications which are associated with morbidity and mortality. Estimating the TBSA is performed by a multitude of different methods, however a gold standard would be ideal. The aim of this study was to compare the estimation of burned TBSA% between 3D photography by Panasonic FZ-M1 Toughpad in conjunction with WoundCare Lite software and expert opinion volunteered by burns doctors...

OBJECTIVE: While the prevalence of burns in children is highest in low and middle-income countries, most research on burn-related pain intensity and distress is carried out in high-income countries. In this study we assessed pain intensity and distress in paediatric patients with burns undergoing wound care procedures without distraction and parental presence in a South-African children's hospital and sought to identify predictors for the outcomes. METHODS: This observational study, carried out as part of a randomized controlled trial, took place at a burns unit in Cape Town, South Africa and included patients between the ages of 0 and 13 years undergoing their first or second wound care procedure...

Corneal neovascularization (CNV) is one of the leading causes of vision loss and a high-risk factor for transplant rejection. The present study proposed a supramolecular hydrogel comprised of MPEG-PCL micelles and α-cyclodextrin (α-CD) for co-delivery of dexamethasone sodium phosphate (Dexp) and Avastin(®) (Ava), and further evaluated its therapeutic efficacy in rat alkali burn model. A physical mixing of Dexp/Ava, MPEG-PCL micelles, and α-CD aqueous solution leads to a spontaneous formation of the supramolecular hydrogel via a "host-guest" recognition between MPEG and α-CD...

In the treatment of traumatic injuries, burns, and ulcers of the eye, inadequate epithelial tissue healing remains a major challenge. Wound healing is a complex process involving the temporal and spatial interplay between cells and their extracellular milieu. It can be impaired by a variety of causes including infection, poor circulation, loss of critical cells and/or proteins, and a deficiency in normal neural signaling (e.g. neurotrophic ulcers). Ocular anatomy is particularly vulnerable to lasting morbidity from delayed healing, whether it be scarring or perforation of the cornea, destruction of the conjunctival mucous membrane, or cicatricial changes to the eyelids and surrounding skin...

BACKGROUND: Changes in microvascular perfusion in scalds in children during the first four days, measured with laser speckle contrast imaging (LSCI), are related to the time to healing and need for surgical intervention. The aim of this study was to determine the accuracy (sensitivity and specificity) of LSCI on different days after injury in the prediction of healing outcome and if the accuracy can be improved by combining an early and a late measurement. Also, the accuracy of LSCI was compared with that of clinical assessment...

BACKGROUND: Burn injury induces immunosuppression and promotes infection with opportunistic pathogens. Pneumonia and sepsis are leading causes of post-burn morbidity and mortality. Fms-like tyrosine kinase-3 ligand (Flt3L) improves local and systemic resistance to P. aeruginosa-associated burn wound infection. This study evaluates the effects of post-burn prophylactic Flt3L treatment on local and systemic infection and inflammation in a murine model of pneumonia and sepsis. METHODS: Mice received a severe scald burn, were treated with Flt3L or vehicle (CTR) for 5 days and inoculated trans-nasally with P...

BACKGROUND: Hypopigmentation is a troublesome often-permanent sequelae after burn injury, particularly in dark races. A number of methods have been described to treat this phenomenon. In this work, we are going to study the effect of E light (intensive pulsed light+radiofrequency+cooling) in repigmentation of partial thickness and full thickness burn wounds in adult patients and light microscopic changes of biopsy material at various stages of repigmentation. PATIENTS AND METHODS: In this study, 24 patients with postburn hypopigmentation were selected and E light was used, using different filters, according to the skin color...

Frostbite is an injury caused by the freezing of tissue, causing varied levels of tissue damage and necrosis. Case reports have shown a positive effect of hyperbaric oxygen (HBO₂) in such injuries, in acute cases as well as delayed (up to 21 days) presentation with complications. In this case report we present the course of hyperbaric treatment of two patients (a brother and sister, age 58 and 62) who sustained frostbite injuries to both feet 28 days earlier while hiking in the Himalayas. They were initially treated in Nepal following local protocol; afterward their primary care in the Netherlands was managed by the Burn Centre at Maasstad Hospital in Rotterdam...

According to the latest report from the World Health Organization, an estimated 265,000 deaths still occur every year as a direct result of burn injuries. A widespread range of these deaths induced by burn wound happens in low- and middle-income countries, where survivors face a lifetime of morbidity. Most of the deaths occur due to infections when a high percentage of the external regions of the body area is affected. Microbial nutrient availability, skin barrier disruption, and vascular supply destruction in burn injuries as well as systemic immunosuppression are important parameters that cause burns to be susceptible to infections...

The control of edema in burn injured patients is a priority as it can impede the wound healing process. Bioimpedance spectroscopy (BIS) has been identified as a method of swelling assessment that has merit after burns. The aim of this study was to examine the reliability and validity of BIS in the measurement of localised burn wound edema across (1) different dressing conditions (no dressing, non silver and silver dressings) and (2) three electrode positions. BIS resistance (R) was hypothesised to be inversely proportional to fluid (edema) volume...
