Mafenide acetate is used in some burn wounds for its ability to penetrate eschar but requires frequent uncomfortable dressing changes for its application. The authors hypothesize that hydrofiber dressings will hold mafenide acetate solution for an extended period of time and maintain antimicrobial activity longer than traditional gauze, thus possibly obviating the need for frequent dressing changes. Four experimental arms included: 1) hydrofiber, stored on a dry well plate as control, 2) gauze saturated with 2.5% mafenide acetate, stored on nonsterile porcine skin, 3) hydrofiber saturated with mafenide acetate, stored on dry well plate, and 4) hydrofiber saturated with mafenide acetate, stored on nonsterile porcine skin. ⋯ Gauze saturated with mafenide acetate did not reliably demonstrate antimicrobial activity beyond 0 hours. Hydrofiber saturated with mafenide acetate, whether stored on a dry well plate or nonsterile porcine skin, consistently possessed sustained antimicrobial activity as demonstrated by zones of inhibition greater than 2 mm to both S. aureus and P. aeruginosa. Mafenide acetate-soaked hydrofiber dressings stay moist and maintain antimicrobial activity against S. aureus and P. aeruginosa for at least 72 hours without repeated soaks.

Self-immolation is a self-destructive conduct described since antiquity. Its frequency is variable from one country to another and it is a real public health problem in parts of the world. In Tunisia, after the 2011 revolution the problem of self-immolation protest has been highly publicized giving the impression of an increase in this phenomenon. ⋯ The self-immolation took place in the victims' homes in 19 cases (46.3%). It came after a conjugal or family conflict in 14 cases (34.1%) and it is of protest character in 8 cases (19.5%). This study confirmed the increasing frequency of self-immolation in Tunisia after the 2011 revolution and noted a change in the victims' profiles.

Electronic cigarettes (e-cigarettes) are novel battery-operated devices that deliver nicotine as an inhaled aerosol. They originated from China in 2007 and their use has rapidly increased worldwide in the past decade, yet they remain largely unregulated. Reports of injuries associated with their use have appeared as unusual events in the news media and as case reports in the medical literature. ⋯ Serious burn injuries from e-cigarettes have recently occurred with greatly increased frequency. The increase in injuries appears out of proportion to the increased popularity of e-cigarettes. The most common pattern of injury is explosion when either the idle device or its batteries are carried on personal attire.

In 2016 the American Burn Association held a State of the Science conference to help identify burn research priorities for the next decade. The current paper summarizes the work of the sub-committee on Burn Wound Healing and Tissue Engineering. ⋯ We then summarize the current state of the science related to burn wound healing and tissue engineering including determination of burn depth, limiting burn injury progression, eschar removal, management of microbial contamination and wound infection, measuring wound closure, accelerating wound healing and durable wound closure, and skin substitutes and tissue engineering. Finally, a summary of the round table discussion is presented.

Recognition of fluid creep has driven a large amount of the scientific investigation in the area of acute fluid resuscitation for burn patients. The role of colloids in ameliorating fluid creep is controversial, despite the fact that a fluid-sparing effect of colloids has been recognized for some time. All but one of the available prospective studies using colloids are more than a decade old, and a modern randomized controlled trial (RCT) comparing crystalloids to colloids is long overdue. ⋯ Use of high-dose vitamin C (ascorbic acid) has become a popular approach to limit fluid resuscitation volumes and edema formation, but it has been investigated in only two clinical studies: one a pseudo-randomized prospective study and the other a retrospective study. Improvements in clinical outcome have not been convincingly demonstrated, and concerns persist surrounding the possibility of induction of an osmotic diuresis, leading to intravascular volume depletion. An RCT is urgently required to evaluate high-dose vitamin C as an adjunct to crystalloid resuscitation compared with the use of crystalloids alone.
