The choking game is defined as a self-strangulation or strangulation by another person with the hands or a noose to achieve a brief euphoric state caused by cerebral hypoxia. Death may occur, but forensic pathologists often classify them as suicides or accidental deaths, without focusing on the possibility that they may result from a deliberate self-temporary-asphyxiation, turned into a deadly game. Presenting two fatal cases of self-strangulation involving an 11-year-old boy and a teenager of 15 years, the authors identify victims' characteristics and death scene's evidence, which may help to distinguish if a death is from an asphyxial suicide or an asphyxial game.

The aim of this is to review deaths associated with the use of Riot Control Agents (RCAs) and to assess how the presenting pathologies is such cases may better inform cause of death conclusions upon autopsy. We also sought to present which additional steps should be added to the Minnesota protocol and the European harmonization of medico-legal autopsy rules in suspected cases of deaths associated with the use of RCAs. We included 10 lethal cases in our study. ⋯ As there are no specific findings in suspected cases of death associated with RCA use, establishing cause of death and whether RCAs are the sole cause or only a contributory factor will be based on the elimination of other possible causes of death. For this reason, a specifically structured autopsy is essential. This specifically structured autopsy should contain basic principles of the Minnesota Protocol and the European harmonization of medico-legal autopsy rules with the following additional steps taken: examination of clothing, eyes, and skin; examination of pharyngeal, tracheobronchial, and eusophegeal mucosas; and a thorough recording of the steps taken by the party conducting the arrest, including other possible causes of in-custody death, as well as a detailed medical history of the deceased.

Intimate partner violence (IPV) is a common occurrence in Australian society and has far reaching health, social and economic impacts, particularly for females who are the most common victims. It is theorised that paramedics frequently encounter IPV in the field and in some cases are the only agency which deal with IPV victims in the out-of-hospital setting. Thus paramedics have a unique opportunity to increase discovery, treatment and reporting, however there is little formal training in managing IPV for most Australian paramedics. ⋯ The vast majority of participants stated that they felt additional education and training would be most helpful to improving their ability to manage IPV cases. Participants had a poor knowledge and poor preparedness for IPV prior to undertaking a targeted education session. There is an urgent need for additional research of the needs and best methods to educate and train paramedics to appropriately respond to IPV cases.

Computerised tomography (CT) is being increasingly advocated to support post mortem investigation of death but the value of using CT data already captured during emergency imaging, prior to treatment of life threatening injuries, remains under recognised and inadequately explored. We demonstrate the value of three dimensional computerised tomography (3D CT) reconstructions of such data, in interpreting the injuries sustained by a male who survived after being subjected to an assault with an axe and whose surface injuries had been debrided and sutured, before any photography was undertaken. ⋯ This case also illustrated the effectiveness of joint interpretation of 3D CT reconstructed images in medico-legal casework, by experienced consultants in forensic pathology and radiology and the potential value of reviewing emergency pre-treatment CT imaging in any serious head injury allegedly sustained in an assault. This is likely to be particularly valuable when sharp or blunt weapon damage to bone is suspected.

The purpose of this study was to evaluate the postmortem distributions of procalcitonin (PCT), C-reactive protein (CRP), soluble triggering receptor expressed on myeloid cells-1 (sTREM-1) and soluble interleukin-2 receptor (sIL-2R) levels in postmortem serum from femoral blood, pericardial fluid and pleural fluid in a series of sepsis-related fatalities (12 subjects) and control cases (20 subjects) that underwent medico-legal investigations. Our aim was to assess the diagnostic potential of the results obtained from pericardial and pleural fluid analysis in identifying sepsis-related deaths. All sepsis-related cases had a documented, clinical diagnosis that was established in vivo during hospitalization. ⋯ Pseudomonas aeruginosa, Klebsiella pnemoniae and Escherichia coli were the most commonly identified bacteria in blood and lung tissue cultures. The preliminary results corroborate the usefulness of PCT, CRP, sTREM-1 and sIL-2R determination in postmortem serum for the identification of sepsis-related deaths. Moreover, the data suggest that, as far as PCT, CRP, sTREM-1 and sIL-2R measurements are concerned, pericardial and pleural fluids can be considered suitable alternatives to postmortem serum should femoral blood prove unavailable at autopsy.
