We have studied the viability of PGF2a as a vitality marker in skin wounds. Incised vital skin wounds and homolateral control pieces of skin were obtained from 20 autopsies performed at the Institute of Legal Medicine of Coimbra University (Portugal). We have also studied 10 fresh skin samples from the Department of Dermatology of the University Hospital (Granada). Our results show that PGF2a is not suitable for the diagnosis of the vitality of wounds because of its irregular behaviour.
[Show abstract][Hide abstract] 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.

[Show abstract][Hide abstract] ABSTRACT: Wound examination is indispensable in forensic practice. It is always necessary to determine wound vitality or wound age to correctly evaluate the relationship between death and any wounds. Thus, the determination of wound vitality or wound age is a classic but still modern theme in forensic pathology. Skin wound healing is a primitive but well orchestrated biological phenomena consisting of three sequential phases, inflammation, proliferation, and maturation. Many biological substances are involved in the process of wound repair, and this short and simplified overview of wound healing can be adopted to determine wound vitality or wound age in forensic medicine. With the development of immunohistochemistry and chemical analyses, the scientific field of wound age determination has advanced progressively during recent years. In particular, it has been demonstrated that collagens, cytokines, and growth factors are useful candidates and markers for the determination of wound vitality or age. In this review article, some interesting and instructive results are presented, contributing to the future practice of every forensic pathologist.

[Show abstract][Hide abstract] ABSTRACT: A critical review is made of the studies on wound healing used for forensic purposes, focusing on the problem of which characteristics indicate that a parameter could be used as evidence in court. A panel analysing the more important information obtained by each marker is given, and a perspective of what might be expected from future research is discussed.
