Healing of burn wounds is often associated with scar formation due to excessive inflammation and delayed wound closure. To date, no effective treatment is available to prevent the fibrotic process. The Renin Angiotensin System (RAS) was shown to be involved in fibrosis in various organs. Statins (e.g. Atorvastatin), Angiotensin receptor antagonists (e.g. Losartan) and the combination of these d...

BACKGROUND Burns are among the most devastating forms of injury. Nowadays the standard treatment for deep partial thickness and full-thickness burn is early excision and grafting, but this technique is not always feasible; and this leads to chronicity and microbial colonization of burn wounds. Interesting properties of human amniotic membrane made us use it in management of chronic infected bur...

This thesis focuses on the evaluation of growth factors, cytokines and chemokines present in the wound environment of burn, chronic and surgical wounds. The first chapters describe a differential expression of these mediators in wound exudates isolated from the 3 different wound types. Our results indicate that development of a universal therapy for these wounds is not an option. Since surgical...

Burns expose the deeper tissues of the skin or body to invasive microbes. Topical preparations for treating burn wounds, to be useful, should ideally have antibiotic power and promote healing. Silver compounds have been the mainstay of topical burn treatment for decades. However, most chemical substances retard wound healing. Several natural agents such as honey and moist exposed burn ointment ...

Surgical intervention of second degree burns is often delayed because of the difficulty in visual diagnosis, which increases the risk of scarring and infection. Non-invasive metrics have shown promise in accurately assessing burn depth. Here, we examine the use of spatial frequency domain imaging (SFDI) and laser speckle imaging (LSI) for predicting burn depth. Contact burn wounds of increasing...

BACKGROND Burn wound infections carry considerable mortality and morbidity amongst burn injury victims who have been successfully rescued through the initial resuscitation. This study assessed the prevalent microrganisms causing burn wound infections among hospitalized patients; their susceptibility pattern to commonly used antibiotics; and the frequency of infections with respect to the durati...

Introduction: Re-epithelialisation of cutaneous wounds is a complex multistep process. In partial thickness wounds, keratinocytes from wound edges and the remnants of the epidermal appendages contribute to the process. We investigated whether the mechanism of injury had any influence on reepithelialisation of partial thickness wounds in a porcine model. Method: Partial thickness wounds were cre...

A period of aggressive surgical treatment of early identification of fungal infection of the burn wound was compared with the previous 5 years' experience with patients suffering from fungal infection of burn wounds. The portion of those patients with Candida infections diagnosed and treated premortem increased from 48.0% to 63.6% and of patients with noncandidal infections from 40.8% to 67.0% ...

A critical need exists for a robust method that enables early discrimination between superficial-partial and deep-partial thickness burn wounds. In this study, we report on the use of laser speckle imaging (LSI), a simple, non-invasive, optical imaging modality, to measure acute blood flow dynamics in a preclinical burn model. We used a heated brass comb to induce burns of varying severity to n...
