Review Case ReportsFatal caffeine overdose: a case report and review of literature.
Caffeine is a central nervous system stimulant that is consumed by large numbers of people on a routine basis, usually in the form of coffee or tea. However, if consumed in high doses, this xanthine alkaloid is profoundly toxic and can result in death. ⋯ Autopsy blood caffeine levels were 350 mg/L. We recommend mandated labeling of pure caffeine anhydrous, highlighting the toxicity risk of ingesting this chemical; and we recommend ensuring that caffeine levels are included in the comprehensive forensic toxicology panel performed on all cases.

Gunshot wounds: a review of firearm type, range, and location as pertaining to manner of death.
Many studies have examined the characteristics of gunshot wounds by manner of death; however, no published study has directly compared these characteristics for the different types of firearms. This study was designed to address that deficiency. Existing data sets of nonaccidental deaths by handguns, shotguns, and rifles were reviewed. ⋯ For both homicides and suicides, there were significant differences between the firearm types for age of victims, range of fire, and wound locations. Possible reasons for those differences are discussed. It is concluded that information about the type of firearm is crucial to have when examining the nature of a firearm injury and determining the manner of death.

The effect of intermediate clothing targets on shotgun ballistics.
The ballistic properties of shotgun shells are complex because of multiple projectiles fired simultaneously that interact and spread out to affect their energy relayed to a human target. Intermediate targets such as clothing can affect penetration into tissues. We studied the effect of common clothing fabrics as intermediate targets on penetration of shotgun shell pellets, using ordnance gelatin to simulate soft tissue and thin cowhide to simulate skin. ⋯ We found that protection afforded by fabrics to reduce penetration of shotgun pellets into tissues was greater at increasing distance from the muzzle beyond 40 yd (36.6 m). The thicker denim and cotton fabrics provided slightly greater protection than polyester. This study demonstrates that clothing modifies the potential wound patterns to victims of shotgun injuries.
