RESUMO
ABSTRACT: Xylazine is an emerging adulterant with fentanyl in fatal drug intoxications, which has public health, safety, and criminal investigative implications. Xylazine is a nonnarcotic sedative used for analgesia and muscle relaxation exclusively in veterinary medicine. Its chemical structure is similar to clonidine and acts as a central α-2 agonist which may cause bradycardia and transient hypertension followed by hypotension. We report the detection of xylazine in 42 deaths in Connecticut from March to August 2019. Xylazine combined with an opioid or stimulant may affect the toxicity of these drugs. Detection of xylazine may help the forensic pathologist distinguish illicit from prescribed fentanyl, and law enforcement agents track the illicit drugs to a specific drug supplier. Because of its lack of response to naloxone, emergency medicine physicians need to be aware of its potential presence as it may affect therapy.

This study on cremation clearance examines whether physical inspections detect more unnatural unreported deaths than medicolegal investigations without inspections. We reviewed all deaths reported to the medical examiner for cremation clearance during 2 distinct years and compared subsequent amendments of death certificates after 2 different investigative methodologies (1 with and 1 without physical inspection). Of 10,367 deaths in 2012, there were 86 deaths (0.83%) in which the investigation with physical inspection resulted in amendments to the death certificate. Of 11,906 deaths in 2016 without physical inspection, there were 153 that resulted in amendments (1.3%) including 2 homicides. For the detection of accidents, there was no statistically significant difference (χ = 0.8119, P = 0.367552). For cremation investigations, the work effort and costs of performing physical inspections do not appear justified given the similar detection rates (approximately 1%) for unnatural deaths among the 2 groups. Both methods, however, do detect unreported unnatural deaths.

Iatrogenic deaths are a concern for patients, physicians, and public health specialists. Most medicolegal investigation jurisdictions in the United States have the legal authority and mandate to investigate deaths associated with diagnostic/therapeutic procedures. Given the decreasing trends of autopsies performed in U.S. hospitals, forensic pathologists are likely to take on an even greater role in investigating these deaths. This is an overview and forensic pathological approach to fatal complications due to diagnostic and therapeutic medical events.
