A total of 76 articles published within the last twenty years, indexed in the PubMed and ResearchGate databases, were reviewed in order to compare medical imaging-based methods of age estimation of children, adolescents and young adults. The evaluated studies were analyzed for any statistically significant differences between the sexes and sides of the body, sample sizes, and population age. Irrespective of the evaluation method, there were some studies that showed a statistically significant differences in ossification stages between the male and female groups. Most of the studies whose authors conducted a statistical analysis demonstrated no significant differences between the left and right side of the body., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 Elsevier B.V.

Overkilling in the Forensic Medicine is known as a specific type of homicide where the number of inflicted injuries greatly surpasses the number of fatal ones. Conducted research aimed to create a unified definition of the phenomenon and its classification criteria by analysing a vast majority of variables concerning its various characteristics. From the population of homicide victims autopsied in the authors' research facility a number of 167 cases were chosen consisting of both overkilling and other homicides. 70 cases were thoroughly analysed based on the completed court files, autopsy protocols and photographs. Second part of the research concerned the facts regarding the perpetrator, used weapon and the circumstances of the act. Conclusions of the conducted analysis allowed to add further characteristics to the overkilling definition: the perpetrators were almost exclusively men, around 35 of age, not related to the victim but might have been in a close relationship with them, often a conflicted one. They did not threaten the victim before the incident. Mostly perpetrators were not intoxicated, and they tried to cover up the homicide in various ways. Perpetrators of overkilling were in most cases mentally disturbed (and thus stated insane), had different levels of intelligence but also a low level of planning before the act - rarely taking actions as preparing the weapon in advance, choosing the scene or luring in the victim., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 Elsevier B.V.

Overkilling in the Forensic Medicine field is known as a specific type of homicide where the number of inflicted injuries greatly surpasses the number of fatal ones. Conducted research aimed to create a unified definition of the phenomenon and its classification criteria by analysing a vast majority of data concerning its various characteristics. From the population of homicide victims autopsied in the authors' research facility a number of 167 cases were chosen consisting of both overkilling and other homicides. 70 cases were thoroughly analysed based on the completed court files, autopsy protocols and photographs. First part of the research concerned the facts regarding the injuries sustained and the victim's characteristics. Conclusions of the statistical analysis allowed to characterize overkilling as a type of homicide where the number of injuries (sharp or blunt) is several times higher than the number of fatal injuries. Sharp force injuries predominate, and are often localized on the torso, neck and limbs, while blunt force injuries are localized mostly on the head. There is no significant dominance between the sexes of the victims, mostly they are in their 40-50's. Victims with reduced abilities to resist predominated (mostly women), which is correlated with the position of their body (lying or sitting) at the begging of the incident. Also overkilling victims more often suffer from defensive injuries and post mortem trauma., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2022 Elsevier B.V.

Unlike amphetamine, amphetamine-like substances accessible on the drug market are less expensive and more easily available; they also produce hallucinogenic effects expected by the users. Such properties render them more attractive as compared to amphetamine. On the other hand, the knowledge of the toxicity of these compounds is very limited, what in consequence generates problems that create ever-expanding research areas, including analytical, clinical and medicolegal issues, thus leading to development of systemic databases. An example here is paramethoxyamphetamine (PMA), which appeared on the drug market in recent years as a result of creative inventiveness of producers of psychoactive substances, who aimed at PMA replacing the popular ecstasy (MDMA) as a less expensive and more available product. It is more potent than MDMA, but has a slower onset of action, which encourages users to take more. The problem is illustrated in the present paper by three fatal cases involving PMA, which were comprehensively investigated taking into consideration case histories, pathological and toxicological findings obtained with the use of LC-MS-MS method. In blood samples taken from all the three victims, very high concentrations of PMA were found (in the range of 10-27mg/L) and thus the cause of deaths was determined as overdoses of PMA with the underlying mechanism of acute cardiorespiratory failure., (Copyright © 2016 Elsevier Ireland Ltd.

In this study, we present 23 cases of dismembered bodies examined by the Cracow Department of Forensic Medicine in 1968-2005 period. Presented material includes 17 instances of defensive mutilation, three instances of offensive mutilation and two cases when dismemberment (decapitation) was a direct cause of death. One case is hard to classified, the perpetrator dissected free skin from the all torso. Analysis of all presented cases and other publications concentrating on the problem of dismemberment gave us the possibility to perform some conclusions. Apart from rare cases of necrophilia, the victim of dismemberment is always a victim of homicide. Homicides ending with corpse dismemberment are most commonly committed by a person close to, or at least acquainted with the victim and they are performed at the site of homicide, generally in the place inhabited by the victim, the perpetrator or shared by both. Such instances are generally not planned by the perpetrator and rarely serial in character.
