The main principle of the determination of the time since death is the calculation of a measurable date along a time-dependent curve back to the start point. Characteristics of the curve (e.g. the slope) and the start point are influenced by internal and external, antemortem and postmortem conditions. These influencing factors have to be taken into consideration quantitatively in order to improve the precision of death time estimation. It does not make any sense to study the postmortem time course of any analyte without considering influencing factors and giving statistical parameters of the variability. Comparison of different methods requires an investigation of the same postmortem interval. For practical purposes, it must be concluded that the amount of literature on estimating the time since death has a reverse correlation with its importance in practice.

Case histories in forensic medicine.

Case histories make up a great part of publications in forensic medicine, especially forensic pathology, although considered low on the hierarchy of evidence based medicine because of its inherent anecdotal nature. Meanwhile some journals exclude case histories categorically from publication. The boom of case histories in forensic medicine has not only opportunity reasons (easily [even mental] and cheap to do) but also structural reasons: due to its tasks in case work many items of forensic medicine can not be simulated experimentally for ethical reasons (violent death, traumatic injuries, sexual assault, poisonings, influence of alcohol and drugs on driving ability and legal responsibility, medical malpractice, adverse events during medical care). In these fields the role of case histories is mainly the augmentation of experience based knowledge. However, quality aspects have to be considered and case histories should be the basis for systematic or hypothesis based research.
