Wound ballistics examines the specific effect, namely the wound profile, of bullets on the body by firing at synthetic models made of ordnance gelatine, glycerin soap and synthetic bones, validated with real cases from (battlefield) surgery and forensic pathology. Wound profile refers to the penetration depth, the bullet deformation/ fragmentation, the diameter of the permanent and the temporary wound cavity. ⋯ The forensic pathologist can draw conclusions as to the used ammunition based on the wound profile. By measuring of the destructive capability of different ammunition types, wound ballistics lays the foundation for guidelines concerning the maximum effect of military ammunition.

Everything in nature and life is occurring in a rhythmic manner. The major “Zeitgeber” is the change of light and dark during a 24 h day. ⋯ A disruption of the circadian rhythm has a high pathophysiological potential. In this article a few basic issues about the role of circadian rhythms and the pathophysiological importance of desynchronisation are reviewed.
