Burn wound infection often involves a diverse combination of bacterial and fungal pathogens. In this study, we characterize the mixed species burn wound infection by inoculating the burn surface with 1 × 103/4/5 CFU of Pseudomonas aeruginosa, Staphylococcus aureus, and Candida albicans in a 1:1:1 ratio. Using the revised Walker-Mason scald burn rat model, 168 male Sprague-Dawley rats (350-450 g) subject to ∼10% TBSA burn injury, with or without inoculation, were evaluated for 11 days after burn. ⋯ Interestingly, within 3 days C. albicans achieved tissue loads of ∼1 × 106 CFU/g, but its numbers were significantly reduced beyond the limit of detection in the burn wound by day 7 in partial-thickness injuries and by day 11 in full-thickness injuries. The pathogenic biofilms contributed to burn depth progression, increased release of HMGB-1 into circulation from injured tissue, and significantly elevated the numbers of circulating innate immune cells (Neutrophils, Monocytes, and Basophils). This robust model of multi-species burn wound infection will serve as the basis for the development of new antimicrobials for combating biofilm-based wound infections.

Extensive burn injury results in a complex immune response that is associated with mortality and prognosis. Studies on acquired immune and the development of sepsis in burn patients have been reported. However, one of the main cells in innate immune, neutrophil dysfunction in the burn shock stage has not been thoroughly characterized. ⋯ Neutrophil dysfunction plays a key role in the development of burn injury. Targeting the restoration of neutrophil function may be a feasible therapeutic intervention to help reduce fluid loss during shock and the severity of subsequent infection.

Burn care is demanding and time intensive. After initial evaluation and treatment, remote follow-up of suitable patients might reduce the on-site workload and efficiency. In this study, the reliability of telemedicine assessment of burn patients and preference of patients to use telemedicine was investigated. ⋯ In the assessment of burn wounds, telemedicine and face-to-face examination resulted in agreement in terms of burn depth, decision of hospitalization and percentage of total body surface area. Although WhatsApp is a reliable method, the majority of patients preferred a face-to-face follow-up. WhatsApp application can be used in remote follow up of eligible burn patients after giving brief information about the procedure.

Burns incidence, mortality and complication rates have been shown to be directly correlated by race, gender and socioeconomic status. As such, socioeconomic status (SES) has been previously highlighted as a target for burn prevention in the UK and abroad. The Queen Elizabeth Hospital, Birmingham (QEHB) is the regional Burns Centre for the Midlands Burn Network, supporting a population of 13.7 million METHODS: 16-year retrospective review was performed of all acute adult burns assessed by the Burns and Plastics Department, QEHB. The data included patient demographics (age, gender, ethnic origin and postcode), mechanism of injury, total body surface area (TBSA) affected and whether first aid was given. IMD Rank, IMD Scores were obtained from individual postcodes, as well as incidence data per electoral ward. ⋯ This study shows patients from the most deprived areas are over-represented in burns incidence and are less likely to perform first aid. We feel this should be highlighted in burns prevention and education strategies.

Laser Doppler imaging is universally considered the most evidence-based method for objective burn depth assessment by accurately predicting burn wound healing potential. This study has analyzed how exactly laser Doppler imaging measurements can be useful in the early therapeutic decision making for patients with clinically indeterminate depth burns. ⋯ Laser Doppler imaging reduces the number of clinical indeterminate depth burns. For these intermediate depth burns on laser Doppler imaging, treatment decisions are based on a combination of interpretation ('man') and laser Doppler imaging measurements ('machine'). Thorough knowledge of confounding factors and validated laser Doppler imaging color code, consideration of surrounding laser Doppler imaging colors, the use of mean flux values, and not directly burn related factors are essential. Burn centers with most laser Doppler imaging experience considered laser Doppler imaging an indispensable diagnostic tool.
