Aim: The aim of the study was to compare the incidence of Messerer fractures in the years 1980–1984 and 2016–2020 in the material of the Department of Forensic Medicine in Kraków and to equate it with the available literature.

Material and methods: Section protocols collected at the Department of Forensic Medicine in Kraków from 1980–1984 and 2016–2020 were investigated. Cases of car-pedestrian traffic accidents were collected and analyzed.

Results: In the 39 cases from 1980–1984, 47 Messerer fractures were present. These reports represented 8.35% of deaths related to car-pedestrian traffic accidents. Among 9 women, Messerer fracture was generally observed in the right femur (41.67%), and the base of the wedge was lateral (41.67%). Whereas among 30 men, it was mainly located in the right femur or tibia (25.71% each). Alcohol was detected among 17 people. While in the 34 postmortem reports from 2016–2020 (15.38% of fatal strikes by a car), 43 Messerer fractures were present. They were usually located in the right tibia (39.5%), then in the right fibula (20.9%) and in the left tibia (14%). The bases of the wedges were mostly lateral (51.2%) and anterior (14%). In contemporary protocols, alcohol was detected among 22 people.

Conclusions: Contrary to the literature data Messerer fractures occur in modern times almost twice as often as in the 80’s. Some differences regarding localization in lower extremities or wedge orientation can be observed.

The study aims to compare suicide poisoning and poisons used to commit suicide in the 1930s and today. The focus is on autopsy protocols from 1930–1939 and 2010–2019 collected at the Forensic Medicine Institute in Krakow. In the years 1930–1939, there were 184 cases, 65 of which were among men and 119 among women. The most common poisons were corrosives, accounting for 69 cases, 43 were carbon monoxide, 24 were drugs and narcotics, 17 were heavy metals, and the remaining 31 were other substances. Of the 138 suicide poisonings in modern times, 96 were committed by men and 42 by women. The most common poisoning was multi-drug poisoning – 62 cases. Opioids, benzodiazepines, neuroleptics and antidepressants were the most frequently chosen substances today. Fatal intoxications with drugs/new psychoactive substances (NCAs) were observed in 28 cases, while other substances were used in the remaining 17. The conducted analysis showed a significant decrease in suicidal poisoning with the use of corrosive substances and gases, while the percentage of drug overdoses is systematically growing. Poisons used for suicide purposes in the 1930s left macroscopic changes that could be instantly noticed during the autopsy. The fact that drugs that are currently used most often do not leave such changes may justify the dynamic development of forensic toxicology.

Aim: The aim of the study was to analyze and compare the most common post-mortem changes which can be found in the body after ligature strangulation and compare it with the most recent literature.

Materials and methods: autopsy protocols from years 2001–2020 gathered in the Department of Forensic Medicine in Kraków were investigated. 37 cases of certain and possible strangulation were found and analysed. Prevalence of ligature strangulation, age, sex, information concerning perpetrator and post-mortem changes were considered.

Results: we found and analysed 37 cases, however only in 16 cases the certain cause of death was ligature strangulation. in the remaining 18 cases the mechanism of death was not precisely defined. in 3 cases advanced late post-mortem changes disturbed establishment of certain identification. Women constituted 87.5% of all victims, while men 12.5%. among 16 certain ligature strangulations we analysed the most important post-mortem changes. Both subconjunctival hemorrhagic petechiae and facial skin petechiae were observed in 93.8% of the cases, laryngeal or hyoid fracture in 56.3%, and hemorrhages in neck muscles were detected in 87.5% of the cases.

Conclusions: The most frequent post-mortem changes after ligature strangulation include subconjunctival petechiae, facial skin petechiae and hemorrhages in the neck muscles which are convergent with the data found in literature. The autopsy may not indicate the circumstance of strangulation.
