A Rare Case of Poisoning with a Volatile Substance: Quantitative Determination of n‐Butane in Postmortem Tissue

Poisoning with volatile substances remains exceptional. Authors report the case of a married couple who were found in a car with a butane gas bottle: the woman was dead and her husband alleged it was an unsuccessful suicide pact. A specific research of volatile substances on postmortem samples with headspace gas chromatography–mass spectrometry following a quantitative determination was performed. The n‐butane concentrations detected were composed of 610 μg/L (cardiac blood), 50 μg/kg (brain), 134 μg/kg (lungs), 285 μg/kg (liver), and 4090 μg/kg (heart) and were compatible with the rare lethal concentrations evoked in the literature. The cause of death was determined to be asphyxiation through n‐butane criminal poisoning. Authors recommendation therefore is to take samples immediately and place them in properly sealed containers and hence analyzing the samples as soon as possible after collecting them or storing them under ?30°C (?22°F) if analyses cannot be performed immediately.     

Influenza A/H1N1 (2009) Infection as a Cause of Unexpected Out‐of‐Hospital Death in the Young*

Abstract: In March 2009, a new strain of influenza A/H1N1 virus was identified in Mexico, responsible for a pandemic. Worldwide, more than 13,500 patients died, most often from acute respiratory distress syndrome. Because sudden death cases were rare, involving mostly young apparently healthy persons, influenza A/H1N1 (2009)‐related deaths may be misdiagnosed, which can raise medico‐legal issues. Case history: we report on an unexpected out‐of‐hospital death involving a young male with no past medical history and no vaccination. Fever was his only symptom. Laboratory tests: histology showed patchy necrotic foci with mononuclear inflammation in the lungs. The heart was histologically normal, but virological analyses using molecular biology on frozen myocardial samples showed high virus load. In conclusion, this case report shows that influenza A/H1N1 (2009) virus can be a cause of sudden cardiac death in the young and demonstrates the importance of quantitative virological analyses for the diagnosis of myocarditis.     

The Value of Outsourcing Selected Cases in a Medical Examiner Population: A 10‐Year Experience

Due to increasing caseloads and inadequate staffing, the burden on Coroner/Medical Examiner Offices to comply with recommended autopsy limits for forensic pathologists (FPs) has been difficult. Since 2006, pathologists at the University of Alabama at Birmingham have performed select autopsies for the Alabama Department of Forensic Sciences. Each case was reviewed by a state FP and scene investigator to determine appropriateness for referral. All referred cases received full postmortem examination including microscopic examination and collection of toxicological samples, and toxicology was ordered by the referring FP as appropriate. The final cause and manner of death were determined by the referring state FP after review of all findings. A majority of the 421 cases were ruled accidental deaths (233), most due to drug toxicity. Of the 178 natural deaths, 118 were attributed to cardiovascular disease. Outsourcing select forensic cases can be educational and an effective tool to manage workflow without compromising quality.     

Deaths Due to Child Abuse: A 6‐Year Review of Cases in The Cook County Medical Examiner's Office

Case files from the Cook County Medical Examiner's Office from 2007 to 2012 were reviewed to analyze homicides due to physical child abuse in children <3 years old. Fatal cases mostly involved younger subjects. Intracranial injuries were the leading cause of death, while death due to extracranial injuries was uncommon. Eyes were involved in most of the cases. Spinal cord was involved in about 1/3 of the cases, mostly in the thoracic area. In some cases, previous injuries were present. There were significant differences in the pattern of injuries between age groups. Subjects showing signs of impact to the head and subjects with no evidence of an impact showed no significant difference in internal injuries. The association of multiple injuries is highly suggestive of child abuse. In suspected child abuse, a postmortem examination including neuropathological, ophthalmological, and radiological information should be always evaluated, together with investigative reports and the medical history.
