Abstract:

Abstract Over-granulation or exuberant granulation tissue is a common problem encountered in the care of chronic wounds, especially that of diabetic foot ulcers. There are several potential options for the treatment of this challenging problem. Some have an immediate short term effect but may have a longer term unfavourable effect, for example, silver nitrate application and surgical excision, which may delay wound healing by reverting the wound back to the inflammatory phase of healing. Other products, such as foams and silver dressings may offer some effect in short term, but their long term effects are questionable. The more recent research supports Haelan cream and tape as an efficacious and cost effective treatment for over-granulation in a variety of wound types. The future of treating over-granulation may lie with surgical lasers, since lasers can not only remove over-granulation tissue but will also cauterise small blood vessels and are very selective, leaving healing cells alone while removing excess and unhealthy tissue. Recently Drs Lain and Carrington have demonstrated the utility of imiquimod, an immune-modulator with anti-angiogenic properties, in the treatment exuberant granulation tissue, in a patient with long standing diabetic foot ulcer, resistant to other forms of therapy. We adapted a modified version of their protocol in the management of a similar patient in our hospital and achieved a good result in lesser time than the former.

Abstract:

The study of wound healing and its treatment is extremely important in veterinary medicine due to the high frequency of wounds and the difficulty in treating wounds by second intention. Thus, the objective of this study was to evaluate the use of a nanofiber membrane made of biodegradable polymers as a method of wound treatment in dogs. This study comprised two dogs with bite wounds. Debridement and cleaning was performed followed by the application of the membrane. In one dog, the wound was in the left proximal calcaneal region with clinical signs of infection, necrotic tissue, and muscle and the gastrocnemius tendon were exposed. The wound displayed rapid formation of granulation tissue which became excessive, so it was necessary to debride several times. However, with the suspension of the use of the membrane, formation of this tissue was not observed, and the wound evolved to epithelialization and fast contraction. In the second dog, there was a deep wound on the medial aspect of the proximal right hind limb, with clinical signs of infection, with muscle exposure. Once the membrane was placed, granulation tissue formed, and the membrane was used until the level of this tissue reached the skin. The wound underwent rapid epithelialization and contraction, without developing exuberant granulation tissue. Efficient wound repair was observed and the dogs exhibited greater comfort during application and use of the membrane. More studies should be conducted in dogs focusing on the application of this membrane until the appearance of healthy granulation tissue, as continued use seems to stimulate the formation of exuberant granulation tissue.

Abstract:

L'objectif de ce travail de recherche est le développement, la mise au point et la validation d'une méthode de spectroscopie multi-modalités en diffusion élastique et autofluorescence pour caractériser des tissus cutanés cicatriciels hypertrophiques in vivo. Ces travaux sont reposés sur trois axes. La première partie des travaux présente l'instrumentation : développement d'un système spectroscopique qui permet de réaliser des mesures de multimodalités in vivo de manière automatique et efficace. Des procédures métrologiques sont mise en place pour caractériser le système développé et assurer la repétabilité les résultats de mesure. La deuxième partie présente une étude préclinique. Un modèle animal et un protocole expérimental ont été mises en place pour créer des cicatrices hypertrophiques sur lesquelles nous pouvons recueillir des spectres à analyser. La troisième partie porte sur la classification des spectres obtenus. Elle propose des méthodes algorithmiques pour débruiter et corriger les spectres mesurés, pour extraire automatiquement des caractéristiques spectrales interprétables et pour sélectionner un sous-ensemble de caractéristiques "optimales" en vue d'une classification efficace. Les résultats de classification réalisée respectivement par trois méthodes (k-ppv, ADL et RNA) montrent que la faisabilité d'utiliser la spectroscopie bimodale pour la caractérisation de ce type de lésion cutané. Par ailleurs, les caractéristiques sélectionnées par notre méthode montrent que la cicatrisation hypertrophique implique un changement de structure tissulaire et une variation de concentration de porphyrine

Abstract:

L’hypoxie contribue à la guérison cutanée via l’induction de HIF-1 (hypoxia-inducible factor-1). HIF-1 gère l’expression de VEGFA (vascular endothelial growth factor A) en se liant au HRE (hypoxia response element) présent au niveau de son promoteur. Par contre, dans le contexte de la guérison cutanée il est incertain si l’hypoxie et HIF-1 contribuent à l’augmentation de l’expression de VEGFA. Pour vérifier cette hypothèse, la guérison cutanée et l’expression de VEGFA ont été étudiées dans un modèle murine, Vegfa/, possédant un HRE non-fonctionnel dans le promoteur de Vegfa. De manière inattendue, le niveau d’ARNm de Vegfa présent dans la peau intacte des souris mutantes était diminué. Par contre, le niveau d’ARNm de Vegfa dans le tissu de granulation n’était pas altéré par rapport à celui de souris normales. Similairement, le niveau d’ARNm des gènes ciblés par Vegfa, Pdgfb et Sdf-1, étaient aussi comparativement diminués dans la peau intacte des souris mutantes mais aucune différence significative ne fut observée dans le tissu de granulation de plaies. L’analyse histologique des plaies en guérison chez les souris mutantes a démontré un tissu de granulation altéré en quantité et qualité (densité de capillaires). Par contre, la différence dans l’épithélialisation et le taux de guérison cutanée entre les deux populations de souris était non-significative. Les résultats démontrent qu’HIF-1 n’est pas un facteur majeur dans la régulation de Vegfa dans le contexte de la guérison cutanée. Cependant, HIF-1 est nécessaire pour maintenir un niveau d’expression basale (Vegfa et ses gènes cibles) adéquate et est aussi nécessaire pour la formation d’un tissu de granulation de qualité optimal suivant une blessure cutanée.
Hypoxia in skin wounds is thought to contribute to healing through the induction of hypoxia-inducible factor-1 (HIF-1), a key transcriptional regulator of genes associated with healing. HIF-1 regulates the expression of vascular endothelial growth factor A (VEGFA) by binding a hypoxia response element (HRE) in its promoter. Although VEGFA is a key regulator of angiogenesis during healing, whether hypoxia and HIF-1 serve to induce its expression in this context is unknown. To test this hypothesis, we studied VEGFA expression and wound healing in the Vegfa/ mouse model, which lacks a functional HRE in the Vegfa promoter. Unexpectedly, decreased levels of Vegfa mRNA were found in intact skin in Vegfa/ mice, whereas levels in granulation tissue during wound healing were not altered. Likewise, mRNA levels of VEGFA target genes Pdgfb and Sdf-1 were decreased in skin but unchanged in granulation tissue in the Vegfa/ mice. Decreased Vegfa levels in skin could not be attributed to decreased HIF-1 protein expression in the skin of Vegfa/ mice, and were therefore the consequence of a loss of HIF-1 responsiveness of the Vegfa promoter. Histologic analyses of healing wounds in Vegfa/ mice revealed significant defects in granulation tissue, both in terms of quantity and capillary density, although epithelialization and healing rates were unaltered. It can be concluded that HIF-1 is not a major regulator of Vegfa during wound healing. Rather, HIF-1 serves to maintain basal levels of Vegfa and VEGFA target genes in intact skin, required for optimal granulation tissue formation in response to wounding.
