Abstract (original English)

Hypertrophic scars and keloids remain a challenge in surgery. We appreciate that our understanding of the process at cellular and molecular level, profound as it is, when it comes to the clinical evidence much is left to be desired. Although the bench to bedside conundrum remains, the science of translational research calls for an even higher level of cooperation between the scientist and the clinician for the impetus to succeed.The clinicians alerted us to the possible theories in the pathogenesis of keloid formation, inter alia, the ischemia theory, mast cell theory, immune theory, transforming growth factor β interaction, mechanical theory, and the melanocyte stimulating hormone theory. All of the above presupposed a stimulus that would result in an uncontrolled upregulation of collagen and extracellular matrix expression in the pathogenesis of the keloid. This bedside to bench initiative, as in true science, realized more ponderables than possibilities.By the same token, research into the epidermal-mesenchymal signaling, molecular biology, genomics, and stem cell research holds much promise in the bench top arena. To assess efficacy, many scar assessment scores exist in the literature. The clinical measurement of scar maturity can aid in determining end points for therapeutics. Tissue oxygen tension and color assessment of scars by standardized photography proved to be usef
