Harness racing injuries and deaths. Report of a fatal accident and review of 178 cases

A case of a harness racing accident in which the driver died of head injuries is presented. To evaluate the victim's head injury and corresponding helmet damage, a videotape of the race was reviewed and analyzed. Based on calculations of a simplified trajectory analysis and testing of the helmet, it was determined that the helmet design did not provide adequate protection for the victim. The standards for harness helmet design are being re-evaluated by the harness racing industry to ensure the safety of the drivers. A review of 178 harness racing injuries and deaths, current harness helmet research, and recommendations for safer helmets are discussed. A protocol for the forensic investigation of sports-related injuries and/or deaths is also presented to assist medical examiners in fulfilling their roles as practitioners of preventive medicine.     

Copper toxicity following massive ingestion of coins

Two hundred seventy-five United States coins were discovered in the stomach of a mentally disturbed individual at autopsy. Many coins containing copper were corroded by prolonged contact with gastric juice, with subsequent absorption and deposition of copper in the liver and kidneys. The patient died from complications related to the acute toxic phase of chronic copper poisoning. A discussion of the case, foreign-body ingestion, gastric bezoars and the mechanism of copper toxicity is presented. To our knowledge, this is the first death due to copper intoxication following a massive ingestion of coins.

Deaths at the workplace. Accidents or homicides?

The medical examiner is responsible for certifying and determining the cause of death of any person dying from criminal violence, accident, suicide, when unattended by a physician, in police custody, or in any suspicious or unusual manner. A less well-recognized, but no less important, responsibility of the medical examiner is the investigation of deaths of individuals who die at the workplace. The manner of death of most job-related fatalities has been traditionally classified as accidental. In recent times, prosecutors have scrutinized these cases more carefully. The results of some investigations have prompted them to bring criminal charges against employers for blatant negligence that contributed directly to injuries and deaths of employees. This paper is devoted to a review of the controversy surrounding the issue of industrial homicide, illustrative cases, and the role of the medical examiner in the investigation of deaths at the workplace.
