Terrorist acts occur every day around the world. Healthcare professionals are often present as bystander survivors in these situations, with none of the equipment or infrastructure they rely on in their day-to-day practice. Within several countries there has been a move to disseminate the actions to take in the event of such attacks: in the UK, Run, Hide, Tell , and in the USA, Fight Back This paper outlines how a very basic medical knowledge combined with everyday high-street items can render highly effective first aid and save lives...

BACKGROUND: Wounds of the finger nail bed represent a frequent injury, especially in children. Residents often learn nail bed repair on patients without prior training. We aimed to develop and evaluate a "low-fidelity" simulation model of nail bed repair. METHODS: The model consists of a false nail on a plastic finger and a hydrocolloid dressing, which is pasted on the nail bed site and cut horizontally. This model allows nail bed suture and nail fixation...

BACKGROUND: Venous leg ulcers are open skin wounds on the lower leg which can be slow to heal, and are both painful and costly. The point prevalence of open venous leg ulcers in the UK is about 3 cases per 10,000 people, and many people experience recurrent episodes of prolonged ulceration. First-line treatment for venous leg ulcers is compression therapy, but a wide range of dressings and topical treatments are also used. This diversity of treatments makes evidence-based decision-making challenging, and a clear and current overview of all the evidence is required...

Biofilms and rapid evolution of multi-drug resistance complicate the treatment of bacterial infections. Antibiofilm agents such as metallic/inorganic nanoparticles or peptides act by exerting anti-bacterial effects and hence do not combat biofilms of antibiotics-resistant strains. In this paper we show that the block copolymer DA95B5, dextran-block-poly((3-acrylamidopropyl) trimethylammonium chloride (AMPTMA)-co-butyl methacrylate (BMA)), effectively removes preformed biofilms of various clinically relevant multi-drug resistant Gram-positive bacteria including Methicillin-resistant Staphylococcus aureus, Vancomycin-Resistant Enterococci (VRE V583) and Enteroccocus faecalis (OG1RF)...

The military has used silver-nylon dressings as a topical antimicrobial on combat-related burns for the past 15 years. However, their clinical efficacy and associated risks have not been evaluated. Herein, the authors document our experience with the use of a specific silver-nylon dressing (Silverlon®) during global evacuation of casualties from combat zones to the United States sArmy Institute of Surgical Research Burn Center. A 10-year retrospective analysis was performed. Variables included patient demographics, total body surface area, length of stay, Injury Severity Score, incidence of urinary tract and burn infections, pneumonia, patient status at the time of discharge, and a composite endpoint...

Introduction: New options are needed to improve wound healing while preventing excessive scar formation. Temporary primary dressings are important options in topical wound management that allow the natural healing process. Methods: We evaluated a novel primary dressing consisting of a biosynthetic, variable porosity, matrix-containing gelatin and Aloe Vera extract and a derivative dressing coated with the anti-scarring agent salinomycin for their ability to promote cell growth, reduce myofibroblast formation, and regulate cytokine production...

Introduction: New treatments that promote wound healing while preventing scar formation are needed. One option in topical wound healing is the use of temporary dressings that allow the natural healing process with minimal scar formation. Methods: We evaluated the temporary wound dressings PermeaDerm C, and a PermeaDerm C derivative coated with the anti-scarring agent, salinomycin (PermeaDerm D) in a pig model of wound healing to show the efficacy of these wound dressings in vivo. Results: Porcine fibroblasts grow well in the presence of PermeaDerm C or PermeaDerm A, and salinomycin reduces excessive myofibroblast formation in porcine fibroblasts in vitro...

BACKGROUND: β-N-oxalyl-L-α,β-diaminopropionic acid (L-ODAP) is a non-protein amino acid with haemostatic property present in Lathyrus sativus. It is considered to be the causative agent of neurolathyrism that occurs upon prolonged overconsumption of Lathyrus sativus seeds. L-ODAP is used as a haemostatic drug in surgical dressings. We previously reported that it can stabilize hypoxia inducible factor (HIF)-1α in normoxic conditions. HYPOTHESIS: We hypothesised that L-ODAP might affect wound healing by modulating cellular proliferation, migration and angiogenesis via HIF-1α stabilization...

Topical antimicrobials are widely used to control wound bioburden and facilitate wound healing; however, the fine balance between antimicrobial efficacy and non-toxicity must be achieved. This study evaluated whether an anti-biofilm silver-containing wound dressing interfered with the normal healing process in non-contaminated deep partial thickness wounds. In an in-vivo porcine wound model using 2 pigs, 96 wounds were randomly assigned to 1 of 3 dressing groups: anti-biofilm silver Hydrofiber dressing (test), silver Hydrofiber dressing (control), or polyurethane film dressing (control)...

The successful treatment of chronic dermal wounds, such as diabetic foot ulcers (DFU), depends on the development of safe, effective, and affordable regenerative tools that the surgeon can rely on to promote wound closure. Although promising, strategies that involve cell-based therapies and the local release of exogenous growth factors are costly, require very long development times, and result in modest improvements in patient outcome. We describe the development of an antioxidant shape-conforming regenerative wound dressing that uses the laminin-derived dodecapeptide A5G81 as a potent tethered cell adhesion-, proliferation-, and haptokinesis-inducing ligand to locally promote wound closure...

New composites based on Ca-alginate hydrogels were produced that release activated charcoal (AC) particles with adsorbed povidone iodine (PVP-I) as a model antimicrobial substance in a physiological-like environment. Composite beads with different alginate (0.5-1.5%w/w) and AC (1-20%w/w) concentrations were analyzed by FE-SEM and characterized regarding textural parameters, swelling, and AC release kinetics. PVP-I was easily adsorbed onto AC particles within the optimized beads (0.5%w/w alginate, 20%w/w AC) as indicated by UV-vis spectroscopy, EDX and FT-IR analyses...

Pyoderma gangrenosum (PG) is primarily, a sterile, inflammatory, neutrophilic dermatosis, characterized by recurrent cutaneous ulceration with mucopurulent or hemorrhagic exudate. The incidence of PG is uncertain, but it is estimated to be about 3-10 patients per million per year. It occurs most commonly on the lower legs, but has been reported at other sites of the body as well. The causes of PG are unknown, but about 50-70% of cases are associated with other diseases, mainly inflammatory bowel disease. We hereby report a case of PG in a 21-year-old male, with a history of ulcerative colitis (UC)...

OBJECTIVE: Wound dressings that use biosynthetic cellulose may be a good alternative to dressings currently used to treat chronic and acute ulcers because their nanostructure is similar to collagen. The objective of this study was to evaluate a wound dressing created with a new material that is composed of a fibrillary network of biosynthetic cellulose. METHODS: A case series of 8 patients in primary healthcare centers in Östergötland county council, Sweden, with chronic and acute lower limb wounds were treated with a wound dressing based on eiratex (S2Medical AB, Linköping, Sweden)...

BACKGROUND: Acrylates and methacrylates are acrylic resin monomers that are known to induce skin sensitization as a result of their presence in different materials, such as nail cosmetics, dental materials, printing inks, and adhesives. Allergic contact dermatitis resulting from the use of modern wound dressings containing them has only rarely been reported. OBJECTIVES: To describe 2 patients who developed allergic contact dermatitis caused by acrylic-based modern medical dressings and/or adhesives...

Open fractures of the leg with large loss of tissue require extensive reconstructive methods that can injure the donor area. The use of negative pressure wound therapy (NPWT) may minimise the impact of these reconstructive methods because of its capacity to create granulation tissue that will form a wound bed for the skin graft, thus reducing the volume of soft tissue defect and saving the donor region. This case study describes the effectiveness of NPWT in the treatment and reconstruction of an open fracture of the leg, with massive loss of soft tissue, associated with elastic intramedullary nailing in a 10-year-old female patient, who was a victim of a car accident...
