Infection is the major cause of morbidity and mortality in burns. Burn wound infection is defined as burn wound bacterial proliferation in a density equal to or greater than 10(5) bacteria per gram of tissue. Gram-negative bacteria, notably Pseudomonas aeruginosa, as well as staphylococci and fungal opportunists, have been identified as prominent invaders. Topical and systemic antimicrobial agents are essential adjuncts in the prevention and treatment of burn wound infection. Topical antimicrobial therapy is indicated in all hospitalized burn patients. Short-term use of systemic antimicrobials for prophylaxis and treatment is required in all moderate and major burns, specifically for early prophylaxis, perioperative prophylaxis, and clinical infection. Antimicrobial choice is based on specific patient or environmental bacteriological data.

Background: Data on trauma burden and outcome varies amongst the nine South African Provinces. In Limpopo Province there is a paucity of data which this study aimed to quantify and characterise the severe trauma burden in the province.
Methods: A retrospective chart review for all patients with injury severity score (ISS) > 16 over a 6-year period (Jan 2015-Dec 2020) at two central hospitals in Limpopo province.

Background: KwaZulu-Natal bears a significant trauma burden, with polytrauma patients often experiencing traumatic limb amputations. This study investigates traumatic limb amputations in the subgroup of severely injured polytrauma patients admitted to the trauma ICU in KwaZulu-Natal. This study aims to describe the management and outcomes of traumatic limb amputations in polytrauma patients at the trauma ICU.

Keloid scars (KS) and hypertrophic scars (HS) are fibroproliferative wound healing defects characterized by excessive accumulation of extracellular matrix (ECM) in the dermis of affected individuals. Although transforming growth factor (TGF)-β is known to be involved in the formation of KS and HS, the molecular mechanisms responsible for its activation remain unclear. In this study we investigated Granzyme B (GzmB), a serine protease with established roles in fibrosis and scarring through the cleavage of ECM proteins, as a potential new mediator of TGF-β activation in KS and HS.

The pathophysiological relationship between wound healing impairment and diabetes is an intricate process. Burn injury among diabetes patients leads to neurological, vascular, and immunological abnormalities along with impaired activities of cell proliferation, collagen production, growth factors, and cytokine activities with huge bacterial infestation. In our study, we aimed to achieve a burn wound dressing material with the help of electrospun Chitosan/Polyethylene oxide/Rosmarinic acid (CS/PEO/RA) nanofibers.
