This article evaluates the criteria for diatom testing in forensic investigations, focusing on drowning cases. Diatoms, unicellular algae found in aquatic environments, are critical to the determination of drowning because water containing diatoms is inhaled during submersion. The primary objectives include defining the exact amount and type of tissue to be analyzed, expressed in terms of diatom concentration relative to tissue weight, and detailing the conditions under which water samples are collected to study the diatom flora at the site.

It is a crucial information for judicial authorities, but current techniques still cannot establish a precise time interval. Novel approaches are therefore required.

- Paranasal sinuses can help identify individuals by comparing post-mortem CT (PMCT) scans with ante-mortem CT (AMCT) scans, but security issues arise when sharing raw AMCT images for suspected identities.
- The study aimed to create an identification score, called IDScore, by analyzing CT slices from two successive AMCTs and assessing their similarities among radiologists.
- The validated IDScore method achieved perfect identification rates (100% sensitivity and specificity) without needing to access full AMCT images, addressing ethical concerns during identity verification.
Article Synopsis
- Post-mortem computed tomography (PMCT) is a valuable technique in forensic medicine for assessing head gunshot injuries, particularly through signs like vault bevelling to help identify entry and exit wounds.
- A new study tested the cutaneous hyperdense rim sign, which could indicate entry wounds, showing high specificity (97%) but moderate sensitivity (63%) when analyzed in 64 cases of gunshot wounds.
- The research found a significant correlation between the hyperdense rim sign and the presence of powder residues or bullet wipe, supporting its potential as an effective tool for determining gunshot entry wounds alongside other forensic methods.
