We report the prevalence and association of secondary brain injuries with the circumstances in which a head injury was sustained. The sample comprised 76 neuropathologically examined medico-legal autopsy cases with an acute primary head injury. Neuropathology reports were analysed to determine the prevalence of various secondary injuries, i.e., hypoxic-ischaemic neuronal injury, brain oedema, and vascular axonal injury (VAI). The prevalences were compared between cases from three distinct injury circumstances, i.e., fall, assault, and strangulation. The sample had a median age of 49 years (interquartile range 27–73) and 71.1% were identified as male. As for distinct injury circumstances, the sample comprised 14 fall cases, 21 assault victims, and 6 strangulation victims. The prevalence of hypoxic-ischaemic neuronal injury was highest in strangulations (100.0%), followed by assaults (81.0%) and falls (64.3%); of specific brain regions, statistically significant differences between the three case groups were found in frontal and parietal cortex (p ≤ 0.018) and the hippocampus (p = 0.005). Brain oedema was present in approximately half of assault (47.6%) and strangulation cases (50.0%), contrastingly to the lower prevalence in falls (7.1%; p = 0.024).

The systematic review aimed to assess changes in salivary hormone levels among perpetrators of violence, with particular emphasis on physical violence, as parameters pointing to perpetrators of violence. Following the inclusion and exclusion criteria, 22 studies were included. Most of the papers included in the analysis came from the USA and Europe. Studies typically included adults as well as children, while focusing mainly on men. Among the hormones, salivary testosterone levels were the ones analyzed most frequently. On the basis of the included studies, a meta-analysis was conducted on the relationship between aggressive behavior and the levels of concentration of testosterone and cortisol measured in saliva. Regardless of gender, individuals exhibiting aggressive behavior were proved to have significantly higher testosterone levels and lower cortisol concentrations in saliva measurements. The obtained results indicate the feasibility of using the examined parameters for initial detection of perpetrators of aggression-related violence.

Sample comprised scans of 2.0 mm resolution of 405 individuals (209 male; 196 female) aged between 19 to 88 years. These scans were reconstructed and visualized using <em>Infinitt</em>. Six clavicular measurements (i.e. maximum length, C1; midshaft circumference, C2; midshaft maximum diameter, C3; midshaft minimum diameter, C4; maximum breadth of the sternal end, C5; and maximum breadth of the acromial articular surface, C6) were obtained from these images.
