Summary
The demand for prosthetic joint replacement surgery will double over the next decade. Complications involving the surgical wound are a devastating complication of this surgery. This randomised controlled trial aims to investigate whether skin cleansing prior to surgical incision with alcoholic iodine reduces the number of patients with superficial wound complications when compared to alcoholic chlorhexidine.

Complications involving the surgical wound are a devastating complication of this surgery. This randomised controlled trial aims to investigate whether skin cleansing prior to surgical incision with alcoholic iodine reduces the number of patients with superficial wound complications when compared to alcoholic chlorhexidine. The study will be performed in patients undergoing orthopaedic joint replacement surgery: a high volume, high cost surgery.Read moreRead less

Summary
Hospital acquired infections continue to rise with over 60% occuring in patients with medical implants. Infections are due to skin bacteria forming a microscopic slime, or biofilm, around the implant. Biofilm infection is only diagnosed after implant removal, responds poorly to antibiotics, and can cause implant failure, such as joint loosening & bone infection in joint replacements and breast deformity with silicone implants.

Summary
It is well known that major burns, as well as being relatively common injuries, are notoriously difficult to manage. Patients exhibit significant variability due to a combination of anatomic, physiologic, hormonal and immunologic alterations occurring both at the wound site and, more importantly, in other body compartments and vital organ systems. Skin burn injury results in the release of multiple inflammatory mediators in addition to significant fluid loss.

Patients exhibit significant variability due to a combination of anatomic, physiologic, hormonal and immunologic alterations occurring both at the wound site and, more importantly, in other body compartments and vital organ systems. Skin burn injury results in the release of multiple inflammatory mediators in addition to significant fluid loss. The distribution of inflammatory mediators and wound bacteria to central organs can cause complex physiological changes that may lead to multiple organ failure, with serious infections occurring in around 50% of patients with serious burns. Antibiotic distribution kinetics, such as bioavailability, clearance, volume of distribution, elimination half-life and unbound fraction in plasma can be significantly altered in burn patients. Without detailed knowledge of changes and relationships between factors such as wound pH, tissue oxygenation, protein concentrations of fluid leaked from the local wound microvasculature, tissue binding, oedema and changes in burned and non-burned tissue induced by resuscitation therapies, the optimisation of both local and systemic infection contriol therapies can hardly be expected to advance. This project aims to determine how changes the physiology of burn patients, in particular in the burn wound environment, affect antibiotic penetration and distribution into tissues. We also believe that these changes will vary between patients and are aiming to determine whether certain parameters can be used to give an indication of the best antibiotic dosing regimens for individual patients.Read moreRead less
Improving The Pre-hospital Treatment And Acute Management Of Burned Children

Summary
Children’s burns are physically and psychologically debilitating and are a huge burden for the children themselves, their families and the Australian health care system. My work will determine exactly what conditions are required to cause burns so that we can act to prevent them. I will also develop more effective first aid treatment and new treatments to improve burn wound healing.
This project aims to improve the acute treatment of children with burn injuries through developing more effective and novel treatments and understanding the conditions required for burn injuries to occur.
Development Of Monoclonal Antibody Therapy For Treating Wounds

Summary
Chronic wounds, diabetic ulcers, injuries in response to trauma, burns and scalds form a medical need which will only expand as the population ages and the diabetic epidemic grows. In our studies, we have shown that Flightless I (Flii), an actin-remodelling protein, is a negative regulator of wound healing. We are developing monoclonal antibodies as a new therapy for reducing Flii levels in wounds which leads to improved wound repair outcomes.

Summary
Scarring is the inevitable outcome of wound repair and can cover a spectrum of conditions, from normal fine lines to unsightly, restrictive and deforming scars. Each year in the world over 100 million patients acquire scars, primarily from surgical procedures. Many of these scars cause considerable problems. Over 4 million burn scars occur every year, 70% of them in children. Poor wound healing is a major clinical problem and can result in loss of movement and deformity.

Each year in the world over 100 million patients acquire scars, primarily from surgical procedures. Many of these scars cause considerable problems. Over 4 million burn scars occur every year, 70% of them in children. Poor wound healing is a major clinical problem and can result in loss of movement and deformity. These are especially important considerations for children, where their growth places extra demands on healing wounds and grafts, necessitating regular surgical adjustment. Scarring is an area of largely unmet medical need and development of new treatment strategies would have significant impact on public health. Changes in cell adhesion, shape and movement are important processes in wound repair. A framework of filaments, much like guy-ropes that support a tent, help coordinate these events. Remodelling of these filaments, shortening or extending them and making new connections, allows cells to change shape and respond to stimuli. This is a crucial event in repairing wounds and the proteins that perform this are fundamentally important to wound repair. We have discovered a protein in skin, known as Flightless, that is involved in this filament remodelling process. The goal of this project is to determine what Flightless does in wound repair. By changing the amount of this protein and comparing its effect in non-scarring and scarring animal wound healing models we can gain insight into its role in wound healing and scar formation in humans. The development of new animal models in this research and the discovery of the role of Flightless in wound repair will provide exciting new opportunities to improve wound repair and reduce scarring, with significant impact on public health.Read moreRead less
