RESUMEN
ABSTRACT: 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. We report on 3 cases in which a loaded firearm discharged when it was dropped, resulting in the deaths of 3 individuals. In 2 cases, the person carrying the dropped firearm was killed, whereas in the third case, a child standing near the person who dropped the weapon was killed. We discuss the risk factors involved in these tragic incidents and present preventive strategies.

ABSTRACT: Suicide by firearm is a significant public health concern in specific regions of the world. Depending on firearm availability, any type of firearm may be used, including handguns, shotguns, and long rifles. Common entrance wound sites in suicidal gunshot wounds include the head, with classic gunshot wound locations including the temple, the forehead, the submental aspect of the chin, and inside the mouth. Occasionally, suicidal gunshot wounds occur in atypical body locations such as the back of the head and neck. Given their relative rarity, suicidal gunshot wounds in these regions may be mistaken for homicides. In this report, we present 5 cases of suicidal gunshot wounds to the back of the head and/or neck. In our series, we focus on differentiating each case from homicides involving gunshot wounds in similar areas of the head and neck.

ABSTRACT: Uterine leiomyomas are the most common pelvic tumor in women and the most frequent indication for hysterectomy. Although benign lesions, leiomyomas can cause dysfunctional uterine bleeding, pelvic pain or discomfort, infertility, and spontaneous abortion. Despite the fact that uterine leiomyomas can result in a significant amount of morbidity, it is relatively rare for these common tumors to lead to death. Here we present a case of fatal pulmonary thromboembolism that occurred due to pelvic vein thrombosis in the setting of leiomyomas.
RESUMEN
ABSTRACT: Despite the implementation of numerous strategies to prevent unintentional burns, fire-related thermal injuries remain a significant source of morbidity and mortality. Unfortunately, fires that occur in the setting of medical oxygen do so despite many safeguards and warnings that accompany oxygen therapy. Oxygen-related accidental fires can occur both within the home and medical settings, and burns associated with these events tend to produce injuries of the face and upper airways. Thermal burns of the face and upper airway are of particular concern because of the vital respiratory function of these anatomic structures, and may initially appear minor, but due to the inhalational injury mechanism, can contribute to death. In this report, three deaths associated with accidental oxygen therapy-related facial/upper airway burns are reported, one occurring during surgery, and two occurring during home-oxygen use.
RESUMEN
ABSTRACT: Pill aspiration is a significant source of foreign body aspiration in the United States and can occur without swallowing dysfunction or illness. Consequences depend on various factors, such as the pill's chemical composition, size, and diagnostic delay. Aspiration of iron tablets poses a higher risk because of hydroxyl radical formation and subsequent caustic burns, inflammation, obstruction, and/or necrosis. We present a case of a middle-aged obese woman who died 3 weeks after aspirating an iron tablet. Autopsy revealed morbid obesity, a necrotic focus in the right middle lobe of the lung, bronchiolar granulation tissue with iron staining foreign matter, extending into an adjacent arteriole, and mural perforation of the hilar right middle lobe. Despite seeking medical attention twice, the patient was only accurately diagnosed postmortem. This case highlights the importance of accurate and timely diagnosis in preventing fatal outcomes. To enhance diagnostic accuracy and reduce morbidity and mortality associated with pill aspiration, clinicians should maintain a high level of suspicion for foreign body aspiration in patients with persistent or worsening respiratory symptoms. Furthermore, it is crucial for forensic pathologists to have a high index of suspicion about the potential for lethal pill aspiration and complications days after the acute event.

Sudden death in infants remains a common and poorly understood cause of childhood mortality in the USA. Pediatric cardiac tumors, although rare, may underlie some cases of unexplained sudden infant death. Autopsy is a crucial diagnostic step in these cases, as both gross and microscopic examination of the heart may uncover occult cardiac tumors. Rhabdomyomas are the most common cardiac tumors in childhood and may result in arrythmia and sudden death. We present a case of sudden death in a healthy 5-month-old infant which initially appeared "SIDS-like" until thorough histological analysis revealed an underlying cardiac rhabdomyoma. The case is of particular importance in that the gross examination of the heart was considered completely normal, and the tumor only involved certain portions of the heart microscopically. Had a single random section of myocardium been the only heart section examined microscopically, the diagnosis might have been missed. This case emphasizes the importance of thorough microscopic examination in infant cases, especially in cases where the heart appears grossly normal.
RESUMEN
ABSTRACT: Spontaneous coronary artery dissection (SCAD) is a rare cause of acute coronary syndrome, occurring when there is separation of the coronary artery walls by intramural hemorrhage creating a false lumen. This compresses the arterial lumen, compromising the ability of the coronary artery to perfuse the myocardial tissue. Spontaneous coronary artery dissection is usually fatal, with risk factors including pregnancy, young age, and female sex, birth control, and other hormonal therapies.In this case report, we describe the case of a 31-year-old biological female transitioning to male with exogenous testosterone who experienced a SCAD. Given the known risk factors for SCAD, such as pregnancy and exogenous hormone therapy, this case raises additional considerations regarding rare unintended consequences of testosterone therapy.

ABSTRACT: Data derived from death certificates (DCs) is an important resource for mortality statistics, disease surveillance, and the creation of public health policies. This study involved the review of COVID-19 DCs occurring during the normal course of DC review for cremation approval purposes in a medical examiner office. During the review process since the occurrence of the pandemic, it was noticed that a significant percentage of COVID-19 DCs being reviewed did not include any comorbid conditions as contributing to death, despite reports, both within the medical literature and within the media, that suggested that most deaths occur in people with known risk factors. The study involved medical record review for COVID-19 DCs that did not list any comorbid conditions. The results indicated that a vast majority of such cases did, in fact, have significant comorbid conditions, such that they should have been listed on the DCs.

ABSTRACT: Railroad-related fatalities in the United States are increasing. A paucity of literature exists regarding the medicolegal death investigation of railroad-related deaths. We report on a subset of deaths in western Michigan, propose protocols for investigating train-related deaths, and propose a stepwise approach for the medicolegal investigation of railroad-related fatalities. Fourteen railroad-related fatalities from 2015 to 2019 were reviewed. Each case was analyzed for demographics, investigative components, train variables, and death certification. The average age was 32 years. Nine decedents involved pedestrians versus trains, and 5 involved motor vehicles versus trains. Male victims were more common, and 50% of the cases were associated with mental illness or recent stressors. Accident was the most common manner of death. With the exception of basic weather conditions, the remaining investigative variables were rarely reported. Image and audio recordings were taken in 3 cases, but railroad companies refused to allow the recordings to be viewed by the medical examiner. We conclude that in addition to a thorough medicolegal death scene investigation and postmortem examination, audio/video recordings are crucial components of death certification in railroad-related fatalities and advocate that medical examiners/coroners be given the legal right to view and retain them.
RESUMEN
ABSTRACT: Concerns about potential increases in suicidal behavior during the coronavirus disease 2019 (COVID-19) pandemic arose in response to reported widespread mental health deterioration. Although early data did not corroborate such concerns, suicide remains a significant cause of preventable deaths worldwide and is of significant interest to public health in the setting of a pandemic. In this study, we present 17 cases of COVID-19-related suicides seen in our West Michigan Medical Examiner's office from 2020 to 2022, which exhibit the complex relationship between mental health and pandemic-related psychological, social, and economic stressors. The relationships were generally categorized as increased anxiety and/or stress due to COVID-19 (5/17 [29.4%]), the loss of social support and/or social isolation occurring as a result of COVID-19 restrictions (5/17 [29.4%]), financial concerns or loss of income as a result of COVID-19 policies (3/17 [17.6%]), grief related specifically to COVID-19 (2/17 [11.8%]), and purported neuropsychiatric sequelae of a prior COVID-19 infection (2/17 [11.8%]). By examining these cases, we highlight ways in which public health systems might prepare for and respond to mental health crises during current or future pandemics and the need for increased collaboration between forensic pathologists and epidemiologists in collating high-quality data during death investigations.
RESUMEN
An accurate assessment of time since fracture is an essential component of abuse and death investigations; however, little evidence-based research exists on dating fractures, especially those of the cranial vault. This is primarily due to difficulties in procuring human fracture specimens of known posttraumatic survival times. The aim of this article is to introduce a new database through which limitations imposed by sample procurement may be mitigated. The Repository of Antemortem Injury Response (REPAIR) is a digitally accessible database of cranial vault fractures of known ages with extensive contextual information and visual documentation in the form of photography, radiography, and histological photomicrographs. This repository is a multifunctional tool that serves as a case submission portal for cranial fractures of known posttraumatic survival time, a sample database for research on fracture healing and rates of repair, a resource for comparative assessments of cranial fractures in forensic casework, and an educational tool for healing fracture histomorphology.

ABSTRACT: Deaths related to exsanguination are not rare; however, most are related to large-caliber blood vessel or organ disruption. This article reports 2 deaths from external hemorrhage arising from superficial lower extremity trauma in persons with peripheral vascular disease and anticoagulant therapy. The first involved a 78-year-old woman who was found unconscious in her home by a relative, with a plastic bag tied around her left foot and evidence of profuse hemorrhage arising from a left great toenail partial avulsion injury. The second involved a 48-year-old male resident of an adult group home who was involved in a physical altercation with a group home employee, who reportedly kicked the decedent in the right shin, resulting in extensive hemorrhage and death. The cases highlight the fact that lethal exsanguination can occur from superficial trauma. Persons with peripheral vascular disease and those taking anticoagulants may be at particular risk for such deaths.

ABSTRACT: While routine medical procedures often impose some level of risk for the patient, death after routine urologic care is rare. In this series, we present 2 cases in which a relatively healthy patient ultimately died after complications, one from a prostate biopsy and one from a total nephrectomy. In case 1, a 58-year-old male died due to a 1500-mL to 2000-mL left retroperitoneal hemorrhage that occurred during insertion of a central line for sepsis treatment that resulted from an infection after a transrectal prostate biopsy. In case 2, a patient who underwent a total nephrectomy for renal cell carcinoma expired on postoperative day 7. Autopsy revealed a 1500-mL hemoperitoneum and an "unclasped" vascular surgical clip with the likely source of origin being the surgical resection site. Performance of an autopsy is essential to ascertain the cause and manner of death after medically related deaths because autopsy results can have implications on patient care, patient safety, and quality improvement.

ABSTRACT: Central pontine myelinolysis is most commonly associated with rapid correction of hyponatremia and has historically been associated with alcoholism. In this case report, 2 deaths with gross findings of central pontine lesions led to the possibility that CPM may have been a potential mechanism of death. Subsequent analysis revealed that these lesions were incidental findings. This case report discusses the importance of appropriate microscopic and immunohistochemical analysis of suspected CPM cases.

ABSTRACT: Urushiol, the active antigen in poison ivy ( Toxicodendron radicans ), is frequently associated with type I and type III hypersensitivity reactions. These reactions most often result in cutaneous symptoms that vary in severity and may at times require medical interventions. Injuries involving other body systems associated with urushiol exposure are far less common. Here, we present 2 unrelated cases of urushiol respiratory exposure status after burning of poison ivy that resulted in cardiopulmonary arrest and ultimately death. In both cases, the history, circumstances, and autopsy findings are consistent with urushiol smoke inhalation having either caused or contributed to death. The cases are unique in that they represent the first cases of death related to poison ivy smoke exposure. Clinicians and forensic pathologists should be aware of the fact that urushiol smoke exposure may lead to morbidity and mortality.

ABSTRACT: The collection of blood and tissue provides an opportunity for an objective comparison of autopsy results. Occasionally, a viable tissue sample is not available during autopsy. Expanding upon collected tissues to include a tissue that is accessible, is a possible drug depot, and is amendable to various analytical techniques may complement information obtained from other specimens. Given its absorption of ions, nutrients, and likely drugs via its rich blood supply, we evaluated the use of submandibular salivary gland tissue as an alternative postmortem specimen. The submandibular salivary glands of 52 decedents were excised. The tissue was homogenized, extracted, and analyzed via liquid chromatography tandem mass spectrometry for 43 opioids and 5 nonopioids. Liquid chromatography tandem mass spectrometry salivary tissue results were compared with the decedent's blood results. Results revealed that opioids were detected in salivary gland tissue at a sensitivity and specificity of 94.4% and 94.1%, respectively. Nonopioid drugs were detected at a sensitivity and specificity of 88.2% and 100.0%, respectively. This study suggests a comparable correlation exists between salivary gland tissue and blood results for certain drugs. Further evaluation is warranted. To our knowledge, this is the first report of salivary gland tissue being used for postmortem toxicology testing in humans.

ABSTRACT: Thromboangiitis obliterans (TAO, Buerger disease) is a segmental, non-atherosclerotic vasculitis that causes occlusion of the small and medium sized vessels of the distal extremities. In rare cases, it can affect vessels in the gastrointestinal, cerebrovascular, coronary, and renal systems. The etiology of thromboangiitis obliterans is unknown, but there is a strong association with smoking in the development and the progression of the disease. We present the case of a 42-year-old homeless female smoker, who was found dead outdoors. Although originally suspected to be a possible trauma-related death, autopsy revealed a thrombus in her left carotid artery, which caused an acute cerebral infarction. It was concluded that thromboangiitis obliterans, likely precipitated by smoking, was the cause of the thrombosis and subsequent death.

Suicide by decapitation as a primary method of injury is not common. When decapitation does occur in association with suicide, it may be a secondary consequence of the primary method of suicide, for example massive blunt force trauma, or hanging with a significant drop; however, primary suicidal decapitation has been described specifically in the context of railway incidents wherein victims lie across railroad tracks in-front of oncoming trains. Herein we report the case of a 49-year-old male who was decapitated after lying-down with his neck atop a railroad track in a railroad stockyard. He was subsequently run over by a train as it began to move to leave the stockyard. This case of train-assisted suicide occurs less often than the more common modality of suicide by train wherein victims stand or jump in front of a moving train or lay their body across the railroad tracks in order to be struck by an oncoming train.

Direct current (DC) electrocution is exceedingly rare, especially in the context of workplace accidents and exposure, where electrical fatality is almost exclusively associated with alternating current (AC). The DC electrocution requires a much higher voltage to cause significant injury and death, and therefore is generally considered safer than AC. Here, we present a case of DC electrocution where a welder accidentally electrocuted himself while repairing a metal plate inside a silo. The decedent had complained of feeling shocks in his arm while welding twice before being electrocuted. Autopsy revealed minimal trauma, along with a classic targetoid electrical burn and punctate lesions likely to be electrical burns. Correlation of the history obtained at the scene and the examination performed at autopsy aided the identification of this rare cause of death.

INTRODUCTION: Loperamide is an opioid available over the counter and in prescription form. Loperamide functions as a µ-agonist within the enteric nervous system to slow intestinal motility. Its antidiarrheal properties and primarily peripheral activity make loperamide an important tool in the management of inflammatory bowel disease. CASE REPORT: A 42-year-old man was found unconscious in cardiac arrest, and emergency medical personnel restored normal sinus rhythm. Family reported complaints of abdominal pain and that he "went through a lot" of loperamide. In the emergency department, the patient exhibited symptoms consistent with an opioid overdose. Mental status improved after administration of naloxone, an opioid antagonist. An electrocardiogram revealed a prolonged QTc interval, which progressed into Torsades de Pointes rhythm during admission. The patient succumbed from hypoxic brain injury, and there was evidence of acute pancreatitis at autopsy. Loperamide and desmethylloperamide (loperamide metabolite) were detected in blood samples. Cause of death was ruled loperamide toxicity. DISCUSSION: Because of reduced central nervous system activity and associated euphoria at therapeutic doses, loperamide abuse is rarely reported. This case demonstrates that an overdose on loperamide can occur in patients seeking symptom alleviation, and may mimic the presentation of opioid overdose.
