What is a vital reaction?

Vital reactions are local reactions of tissues at the site of damage. Vitality and wound healing or wound age estimation are phenomena which are closely related to each other, in particular with regard to skin lesions. Wound age describes the time interval between the infliction of an injury and the time of death.

How do you determine the age of a wound?

Total RNA of sufficient quality and quantity can be obtained using biological stains that are several months, even years, old [29–31]. Thus, the mRNA levels of inflammatory cytokines and wound-healing factors are assayed using the real-time polymerase chain reaction (PCR) to evaluate wound age.

What is wound age?

Currently, the wound age is a principal parameter in forensic investigations. It is essential to determine the time of wounds whether it occurred before or after death. It can be determined using immunohistochemical techniques, growth factors and cytokines.

Which enzyme would be observed in high concentration for an aged wound of 8 hours or above?

As early as 1/2 hour after vital wounding the epidermis and hair follicles in the vicinity of the wound edge revealed an increased esterase activity. This increase in esterase activity was seen in wounds up to 8 hours old, disappearing in wounds older than 16 hours.

Is death an injury?

The legal definition of a bodily injury is roughly the same as the definition used by insurance companies: any physical sickness or injury to the physical body is a bodily injury, including death if the victim died from a physical sickness or injury.

What is wound in forensic science?

Is death a physical injury?

How are vital reactions used in forensic medicine?

Systemic and local vital reactions are in the focus of forensic research. There is much progress in the field of immunohistochemistry and molecular pathology. Postmortem imaging provides the possibility to prove vital signs. The question whether an injury was sustained during life or not is one of the most important subjects in forensic medicine.

Why is a vital reaction a valid phenomenon?

According to Bernhard Knight [ 112] a “vital reaction” (VR) is a dubiously valid phenomenon, mainly due to the fact that death and dying is a process and not an event [ 127, 128, 132, 133, 142 ]. It is rather the proof that a specific system, organ, tissue, cell or metabolic process was still functional.

Which is the most important subject in forensic medicine?

There is much progress in the field of immunohistochemistry and molecular pathology. Postmortem imaging provides the possibility to prove vital signs.

What is the aim of a vital reaction review?

The aim of the present review is to provide an update on forensically relevant vital signs/vital reactions. Systemic vital reactions especially of the circulatory and respiratory system as well as local vital reactions will be addressed.
