Klebsiella pneumoniae is one of the predominant pathogens in burn wound infections, and prevalence of multidrug resistant strains has further complicated the situation. An increased interest in phage therapy as a means of combating infection has been accruing in recent years. In order to overcome the drawbacks associated with phage therapy, the present study was conducted to evaluate the potential of liposomes as a delivery vehicle for phage in the treatment of burn wound infection. ⋯ The results showed the potential of liposome entrapped phage cocktail for treating Klebsiella pneumoniae mediated infections. Thus, this strategy can serve as an effective approach for treating Klebsiella mediated burn wound infections in individuals who do not respond to conventional antibiotic therapy.

Keloids are abnormal fibroproliferative scars that pose a significant challenge to patients and clinicians. The molecular basis for keloid formation remains incompletely understood, and currently no universally effective treatments exist. It is well recognized that keloids are more prevalent in populations with darkly pigmented skin, such as African Americans, but the basis for the link between skin color and keloid risk is not known. ⋯ Further, the percentage of epidermal cells displaying nuclear VDR localization was significantly lower in keloid scars compared with normal skin samples. Interestingly, analysis of VDR-positive nuclei among different normal skin samples showed a significant reduction in nuclear localization in epidermis of black donors compared with white donors. The results suggest that VDR may play a role in keloid pathology, and hint at a possible role for VDR in the increased susceptibility to keloid scarring in individuals with darkly pigmented skin.

This study compared different energy densities of laser on second degrees burns in rats aiming to determine the most effective dosimetry in stimulation of the healing process. ⋯ The energy density of 9.86J/cm2 was more effective in promoting cellular responses related to neoangiogenesis, decreasing inflammation and collagen fibers reorganization.
