RESUMO
Impaired wound healing complicates a wide range of diseases and represents a major cost to healthcare systems. Here we describe the use of discarded wound dressings as a novel, cost effective, accessible, and non-invasive method of isolating viable human cells present at the site of skin wounds. By analyzing 133 discarded wound dressings from 51 patients with the inherited skin-blistering disease epidermolysis bullosa (EB), we show that large numbers of cells, often in excess of 100 million per day, continually infiltrate wound dressings. We show, that the method is able to differentiate chronic from acute wounds, identifying significant increases in granulocytes in chronic wounds, and we show that patients with the junctional form of EB have significantly more cells infiltrating their wounds compared with patients with recessive dystrophic EB. Finally, we identify subsets of granulocytes and T lymphocytes present in all wounds paving the way for single cell profiling of innate and adaptive immune cells with relevance to wound pathologies. In summary, our study delineates findings in EB that have potential relevance for all chronic wounds, and presents a method of cellular isolation that has wide reaching clinical application.

El objetivo de este trabajo es investigar la utilidad del uso de Cianocrilato en la síntesis de heridas de fimosectomías realizadas en el Hospital "Miguel Pérez Carreño" durante el período de enero a diciembre de 2003. Se realizó estudio prospectivo, procediéndose a la síntesis de heridas de fimosectomías con Cianocrilato en 10 pacientes y comparándose en 10 pacientes en quienes la síntesis se realizó con Catgut Crómico, tomando en cuenta el tiempo utilizado en la síntesis, dolor, complicaciones y el tiempo para reinicio de relaciones sexules. Con el uso de Cianocrilato no se evidenciaron cicatrices hipertróficas. El tiempo utilizado en la síntesis con Cianocrilato fue significativamente menor que con la sutura (P<0,0001), al igual que el dolor a las dos semanas de postoperatorio (p<0,000092) y el tiempo de reinicio de relaciones sexuales (P<0,00033) con un valor de 4.87 y 11.03 días más corto
