SARS-CoV-2 (COVID-19) Experience at an Academic Medical Examiner's Office.

Introduction: The coronavirus disease of 2019 (COVID-19) pandemic has resulted in a great deal of morbidity and mortality worldwide. Since most deaths related to COVID-19 are currently considered natural, and they tend to occur following a clinically recognized illness, many medical examiner/coroner offices within the United States do not take jurisdiction over the majority of COVID-19 deaths.

Methods: In this review, we present the experience of a medium-sized medical examiner's office affiliated with an academic medical school institution, over the first 15 months of the COVID-19 pandemic.

Sudden Death Due to Necrotizing Fasciitis After Routine Cervical Radiofrequency Ablation Treatment.

Cervical facet joint neurotomy, also known as cervical radiofrequency ablation (RFA) or cervical facet rhizotomy, is a medical procedure aimed at alleviating chronic neck pain caused by issues related to the cervical facet joints through ablation of neurons (J Pain Res 2021;14:2807-2831). Although generally safe, adverse events can occur. Infection is a rare consequence of this procedure.

Lethal Complications of Meningiomas: A Case Series.

Background: Meningiomas are the most prevalent type of primary intracranial tumor in adults, comprising nearly one-third of all intracranial tumors. They are typically benign, slow-growing, and asymptomatic but may cause neurological symptoms as they expand due to mass effect. Classification is determined by World Health Organization (WHO) grades 1 to 3 following pathological examination corresponding to benign, atypical, and anaplastic (malignant), respectively, reflecting their rate of growth and risk of recurrence.

Accidental Gunshot Wound Fatalities Related to Dropped Firearms.

A death resulting from the accidental discharge of a firearm represents a rare but oftentimes preventable tragedy. Such deaths may occur in a variety of settings. One such setting involves the discharge of a loaded firearm, which occurs when it is accidentally dropped, thrown, or falls to the ground.

Cutaneous skin defects overlying tangential gunshot wounds: A case series.

In examining deaths resulting from gunshot wounds, it is important to describe the wound pathway created by the projectile. Forensic pathologists must identify all entrance and exit wounds and account for all projectiles. Occasionally, confusion arises as to whether a skin defect represents an entrance wound or not, an exit wound, or some other type of wound.

Fatal Complication of Mouthguard Used to Treat Awake Bruxism in Patient with Frontotemporal Dementia.

Awake bruxism is an understudied manifestation of frontotemporal dementia, yet awake bruxism can have fatal consequences in the aging population. This report presents a patient suffering from awake bruxism associated with frontotemporal dementia being treated with a mouthguard, which ultimately becomes lodged in her posterior oropharynx leading to asphyxiation. The case highlights the need for investigation into the occurrence and treatment of awake bruxism among patients with dementia, and the unique risk-benefit analysis that must be performed to develop proper treatment plans for patients with dementia.

Positional Asphyxia in Opioid-Related Deaths: Is It Being Overlooked?

The contribution of positional asphyxia in opioid-related deaths is currently unknown. Diagnostic criteria for positional asphyxia include finding the decedent in a position that does not allow for adequate respiration and an inability to extricate themselves from the position due to various conditions. Our primary objective was to assess whether positional asphyxia and the resulting airway compromise were a contributing factor to death due to the toxic effects of opioids.

Neuropathology in Consecutive Forensic Consultation Cases with a History of Remote Traumatic Brain Injury.

Traumatic brain injury (TBI) is widely assumed to be causal in neurodegenerative disease, based on epidemiological surveys demonstrating an increased risk of Alzheimer disease (AD) following TBI, and on recent theories surrounding repetitive head movement. We tested this assumption by evaluating 30 consecutive forensic examinations in which neuropathology consultation was sought, and in which a history of remote TBI was uncovered during the course of the investigation. In this series, there was a high frequency of psychiatric co-morbidities (100%), remote contusion (90%), and seizures (63%).

A Case Series of Anterograde and Retrograde Vascular Projectile Embolization.

Deaths related to firearms are common within the United States, with most cases having conspicuous projectile wounds found at autopsy. Individual gunshot wounds may be perforating or penetrating. In most cases with penetrating wounds, projectiles are relatively easily found via radiography and by following the pathway on internal examination.

Can Neck Contusions in Unexplained Pediatric Deaths be Explained by Cardiopulmonary Resuscitation?

The distribution of cutaneous contusions in infants may raise the possibility of maltreatment. Neck contusions are particularly problematic since they seldom occur outside the setting of abuse, while cardiopulmonary resuscitation (CPR)-related maneuvers may involve the neck. To address the role of CPR in neck findings, we examined 260 consecutive pediatric autopsies in which CPR was attempted.

A Unique Type of Birth Trauma Mistaken for Abuse.

Pediatric abusive head trauma is a challenging subject across many disciplines. Of particular importance is the identification of mimics of abuse, so cause and manner of death can be properly assigned. We present the case of suspected child abuse involving an infant who presented unresponsive to the hospital with hypoglycemia, hypothermia, and bilateral parietal fractures.

Autopsy Fingerprint Technique Using Fingerprint Powder.

The collection of high-quality fingerprints is an important component of routine forensic autopsies and represents one of the several potential methods for identifying a decedent. Fingerprint collection at autopsy frequently employs a manual method using fingerprint ink and cards, although some offices use digital-scanning equipment. While these methodologies are adequate in most circumstances, this study introduces an alternative method using fingerprint powder and adhesive labels.

Gabapentin in Mixed Drug Fatalities: Does this Frequent Analyte Deserve More Attention?

From 2000 to 2014, drug overdose deaths increased 137% in the United States, and 61% of these deaths included some form of opiate. The vast majority of opiate-related drug fatalities include multiple drugs, although there is scant data quantitatively describing the exact drugs that contribute to deaths due to multiple drugs. In the present study, we sought to quantitatively identify the drugs that occur with opiates in accidental multidrug-related fatalities.

Inhibition of the Sur1-Trpm4 channel reduces neuroinflammation and cognitive impairment in subarachnoid hemorrhage.

Background And Purpose: Subarachnoid hemorrhage (SAH) can leave patients with memory impairments that may not recover fully. Molecular mechanisms are poorly understood, and no treatment is available. The sulfonylurea receptor 1-transient receptor potential melastatin 4 (Sur1-Trpm4) channel plays an important role in acute central nervous system injury.

Cocaine-induced intracerebral hemorrhage in a patient with cerebral amyloid angiopathy.

Intracerebral hemorrhage (ICH) is a well-recognized complication of recreational cocaine use. The precise mechanism of the cocaine-induced hemorrhagic event is unclear, although multiple factors have been implicated. We report a case of a 62-year-old woman who suffered left parieto-occipital ICH with herniation and death, following a cocaine binge.

Collembola of the grave: a cold case history involving arthropods 28 years after death.

This report describes a cold case in which a cadaver of a 28-year-old female was exhumed in February 2005 from a cemetery in Battle Creek, Michigan. She had sustained a gunshot wound to the head and was found dead in her home on November 15, 1977. The body of the victim was subsequently embalmed and then buried at a depth of 1.

Medical examiners, coroners, and biologic terrorism: a guidebook for surveillance and case management.

Medical examiners and coroners (ME/Cs) are essential public health partners for terrorism preparedness and response. These medicolegal investigators support both public health and public safety functions and investigate deaths that are sudden, suspicious, violent, unattended, and unexplained. Medicolegal autopsies are essential for making organism-specific diagnoses in deaths caused by biologic terrorism.

Punched with a fist: the etiology of a fatal depressed cranial fracture.

We report a case in which a 33-year-old man was discovered unconscious following a fistfight with another man. Emergency neurosurgical efforts to repair a depressed temporoparietal skull fracture and associated brain injuries were unsuccessful. The forensic anthropologist and pathologist worked in tandem to sort out a complex combination of cranial evidence, including healed antemortem trauma, perimortem blunt force trauma, remote and recent neurosurgical intervention, and the craniotomy cut performed at autopsy.
