title: Diagnostic ability of D-dimer in the establishment of the vitality of wounds.
abstract: The potential of skin measurements of D-dimer (DD), a specific derivative of crosslinked fibrin, for the diagnosis of the vital origin of wounds was investigated in 67 human vital skin wounds and homolateral control pieces of skin from 53 autopsies performed at the Institute of Legal Medicine of Coimbra (Portugal) during 1992. Our results demonstrate that DD levels for the incised vital skin wounds (n = 50) were much higher on average than their controls (P < 0.01) which were actually incised injuries produced postmortem at the autopsy. We did not find any statistical difference in average DD levels among the remaining injuries (seven abrasions and ten contusions) in comparison to their respective controls. DD may be used, with certain limitations, as a marker of the vitality of incised wounds. The authors believe this is the first time this marker has been applied in forensic pathology. It is an example of an easy and quick application technique, with the added advantage of low cost.
