RESUMO
ABSTRACT: Female homicide is a broad term that includes any homicide in which the victim is a female, representing the most extreme form of violence against women. This study investigated the characteristics of female homicides to determine the types and characteristics of injury, circumstances of the events, and other aspects in this specific population. The Cook County Medical Examiner's Office files were searched for homicides in female subjects between January 2017 and January 2022, with no limits for age, race, or cause of death. A total of 527 cases met the criteria. Most homicides occurred in Chicago during the summer. The most common cause of death was firearm(s) wounds, followed by sharp force traumas, asphyxia, and blunt force injuries. The remaining deaths were due to combined and "other" mechanisms. Different patterns of injuries were observed at the autopsy. Alleged offenders were mostly male subjects and were frequently in a romantic relationship with the victim, and the reasons for homicide were related to jealousy and personal conflicts. This study offers an overview of homicidal deaths in female subjects in a large metropolitan area.

ABSTRACT: Gunshot injuries are one of the leading causes of death from trauma in the United States. In recent years, the US has experienced an increasing number of fatal pediatric cases related to firearms.A search of the database of the Cook County Medical Examiner's Office over the period January 2016-December 2021 revealed 418 deaths by gunshot wounds (GSWs) among people aged between 0 and 18 years old. Subjects were subcategorized in infants (0 to 1 year), toddlers (≥1 to 3 years), preschool (≥3 to 6 years), preadolescents (≥6 to 12 years), and adolescents (≥12 to 18 years).Most victims were males (n = 374) and adolescents (357 males and 30 females). Homicide (n = 373) was the most common manner of death. Only 2 deaths were accidental. Single GSWs deaths (n = 232) were more common than multiple GSWs (n = 186) and preferentially directed to the head in both homicides and suicides. Gang or robbery related events in areas of readily available firearms explained 4.5% of homicides (17 out of 373 cases). Among deaths by self-inflicted GSWs (n = 36), 7 cases were linked to psychiatric disorders, 3 to family difficulties, 2 to history of playing Russian roulette, and 2 to bullying at school.Pediatric gunshot injuries and deaths are an important public health problem. Understanding and addressing individual and societal risk factors should be the first step toward prevention.
RESUMO
ABSTRACT: Since January 2023, a series of fatalities has occurred in the Cook County Jail. Upon reviewing surveillance videos, in some cases, the inmates shared paper strips, and it was followed by the onset of labored breathing and loss of consciousness. Scene investigation revealed burnt paper strips near the body in 3 cases. No trauma was observed during autopsy. The expanded toxicology panels did not detect any illegal drugs in the postmortem blood samples. However, additional analysis specifically targeting synthetic cannabinoids revealed the presence of MDMB-4en-PINACA [methyl 3,3-dimethyl-2-{[1-(pent-4-en-1-yl)-1H-indazole-3-carbonyl]amino}butanoate], a synthetic cannabinoid associated with a wide range of adverse effects, including cardiovascular complications such as tachycardia and hypertension, respiratory depression, and acute kidney injury. There is limited research on the lethality of MDMB-4en-PINACA. This case series suggests that even isolated use can potentially lead to death. This study aims to raise public awareness regarding MDMB-4en-PINACA, highlighting its unpredictable effects and potential for severe adverse reactions, and to facilitate the development of effective prevention and harm reduction strategies. Implementing screening methods in correctional facilities is crucial to prevent the circulation of potentially fatal substances.
RESUMO
Sudden cardiac death is a phenomenon that affects more than 200,000 individuals annually in the United States. Among sudden cardiac deaths, only a fractionally small portion is thought to be attributable to intracardiac neoplasms. Though rarely implicated as the primary cause of death, cardiac myxomas are the most common benign neoplasms of the heart and have been known to cause death due to multifactorial embolic events, fatal arrhythmias, and frank obstructive events. In this case, a healthy, asymptomatic young male was found unresponsive in his residence. Examination of the heart at autopsy revealed dilation of the right atrium and a large, hemorrhagic, irregular, and obstructing mass arising from the right atrium, consistent with cardiac myxoma. When unusual cardiac findings are discovered at autopsy, a systematic investigation of the heart, including retaining the organ for cardiac pathology consultation, is mandatory to correctly identify the cause of death.
RESUMO
Purpose The role of cadaver labs in preparing new generations of effective neurosurgeons is of paramount importance. The Authors describe a personal cadaver lab experience aimed at improving the knowledge of a difficult region of the central skull base. The anterior and middle incisural spaces are regions of remarkable anatomical, and surgical interest due to complex relationships between bony, dural, arachnoidal, and neurovascular structures. The primary purpose of this study is (1) to describe the anatomy of this region with particular emphasis on the relationships between the anterior margin of the free edge of the tentorium and the sphenoid and petrous bone; (2) to identify surgical implications in many different types of neurosurgical procedures dealing with this challenging complex anatomic area.Methods Eight fresh, non-formalin-fixed non-silicon-injected adult cadaver heads and five injected formalin-fixed adult cadaver heads were analyzed in this study.Results The anatomical study was focused on the description of the relationships between bony, dural, arachnoid, and neurovascular structures. Surgical implications are described accordingly.Conclusions Detailed anatomical knowledge of this region finds concrete applications in neurosurgical practice since the anterior and middle incisural spaces are often surgically exposed in neoplastic and vascular diseases.

ABSTRACT: Eutylone is an emerging synthetic stimulant that is quickly gaining popularity due to its affordability and wide availability. A recent surge has been observed in Upstate New York. This study presents a retrospective review of deaths in which eutylone was identified in postmortem samples from January 2018 to December 2021 in the electronic database of the Onondaga County medical examiner's office in Syracuse, NY. Of the 176 subjects who met the study criteria, 128 (73%) were male and 48 (27%) were female, with a mean age of 37.6 years. Most of the subjects were listed as White (89%), followed by African American (9%). Most of the cases had multiple medical comorbidities (89%), with anxiety and hypertension being the most common illnesses. Chromatography/mass spectrometry was used to perform a qualitative analysis of femoral blood and urine samples to detect multiple drugs, including eutylone. Substance abuse disorder was present in 135 (77%) cases, with opiates and cocaine being the most common additional drugs detected. The most common cause and manner of death were drug toxicity and accident, in 137 (78%) and 143 (81%) cases, respectively. Overall, the study suggests that eutylone is a growing concern in Upstate New York, and its use is increasing in prevalence. Policymakers and health care providers should take steps to address this emerging issue and prevent further harm to individuals and communities affected by drug overdose.

Found in virtually any organ system, immunoglobulin (Ig) G4-related disease (RD) is a recently recognized immune-mediated, systemic, a fibroinflammatory disease characterized histologically by storiform fibrosis, obliterative phlebitis, and lymphoplasmacytic infiltrate with IgG4-positive plasma cells (PCs). IgG4-related Hashimoto thyroiditis (IgG4-RHT), also called IgG4-related thyroiditis, shares many features with IgG4-RD but is distinct in several ways. A case of IgG4-RHT in a 51-year-old African American female is assembled together with a literature review which uncovered 82 cases of IgG4-RHT. The findings and criteria which the respective authors used to reach their diagnoses are analyzed. Findings common to all studies are lymphoplasmacytic infiltration and IgG4-positive staining, while most describe follicular atrophy (95.2%, 79/83). Stromal fibrosis involving >33% of thyroid architecture was reported in 74% (58/78) of cases. While few reports observed storiform fibrosis, all describe lack of obliterative phlebitis or systemic involvement. Discrepancies between reports exist in immunostaining thresholds, as well as grading systems for stromal fibrosis. Based on our review of the literature and experience, we propose a set of best practice recommendations for the diagnosis of IgG4-RHT. Our diagnostic criteria are (1) lack of extrathyroidal IgG4-RD, (2) the fibroinflammatory process should not extend beyond the thyroid capsule, (3) stromal fibrosis comprises at least 30% of the involved tissue, (4) >30% IgG4/IgG ratio, with absolute immunostaining cutoffs varying by the degree of stromal fibrosis: for >50% stromal fibrosis use >20 IgG4+PCs/HPF, for 30% to 50% fibrosis use >30 IgG4+PCs/HPF, (5) fibrosis infiltrates the interlobular/interfollicular space, (6) features of follicle injury, and (7) obliterative phlebitis is not required.

ABSTRACT: In laymen's terms, it can be difficult to communicate how much force is needed to create a stab wound into a person's chest. Previous work has determined the force to puncture the skin, rib cartilage, or bone but without putting the results in terms that are easy to understand.The purpose of this study was to determine the force needed to puncture 3 types of fruit using 3 different types of knives, namely, a steak knife, a butcher's knife, and a lock-blade knife, to help put these previous results in perspective.There was wide variation in the force required to insert a knife into different fruits, but no force for any knife at any location for all fruits exceeded 93.1 N. Results show that force needed to penetrate the skin and allow for an 8-cm blade penetration into the chest is similar to the force required to insert a steak knife for a 6-cm distance into a cantaloupe. In addition, the force needed to penetrate the cartilage is most similar to stabbing a watermelon to 6 cm with a butcher knife. However, the forces required to penetrate the bone are greater than those required to penetrate any fruit with any type of blade.

ABSTRACT: Adrenal crisis is a life-threatening manifestation of acute adrenal insufficiency. One of the most important underlying causes is Addison disease (primary adrenal insufficiency).A 42-year-old White woman with a medical history of Addison disease on chronic steroid therapy was admitted to the emergency department due to sustained episodes of cardiopulmonary arrest. Upon admission, she was hypotensive and hypoglycemic. Despite resuscitation attempts, she developed multiorgan failure and eventually died. At autopsy, no definitive adrenal gland tissue was grossly identified, but histology detected atrophy of adrenal glands with patchy chronic inflammation. Evidence of acute pneumonia was seen. The cause of death was determined to be complications of adrenal/Addisonian crisis.A review of the literature showed only a few autopsy studies regarding deaths due to adrenal crisis. Forensic pathologists should include adrenal crisis in their differential diagnosis. Adequate medical history and pertinent autopsy findings can corroborate deaths due to adrenal crisis, but exhaustive biochemical analyses are mandatory to support the diagnosis further.

ABSTRACT: When investigating deaths due to stab wounds, a common question asked to the forensic pathologist concerns the force required to inflict a given wound.In this study, tests were performed on 6 human cadavers. A material testing machine was used to produce the stab wounds and to record the force required to penetrate skin, muscle, cartilage, and rib bone of the chest. Three different blades were used: a steak knife, a butcher knife, and a lock-blade knife. On each cadaver, chest injuries were produced at the following locations: (a) skin, intercostal soft tissues; (b) skin, muscle, and cartilage; and (c) skin, muscle, and bone. After the experiment, a chest dissection was performed to confirm the correct locations of the produced stab wounds.The force required to insert a knife into cartilage or bone was significantly greater than the force to insert it into a region only covered by skin. There was wide variation in the force required to insert a knife into different bodies, but no force for any knife at any location for all bodies was greater than 261 N.This study allowed us to obtain quantitative measures of the force required to penetrate human chest tissues, removing subjective factors.

The primary medico-legal investigation goal in deaths due to animal attacks is distinguishing between animal-related injuries and potential homicidal wounds. We report the case of a 49-year-old male found dead in his farm's pigsty, where a sow and her piglets were present. At the postmortem examination, numerous, severe blunt force injuries were observed on the body, with special regard to the upper extremities where massive injuries involving soft tissues, bones, and regional vessels, tendons, and nerves were present. The death resulted from severe bleeding from massive upper extremities injuries due to a domestic pig attack. Domestic pigs are usually placid but they can become aggressive if disturbed and attack humans producing severe injuries due to trampling, kicking and biting. Knowing the relevant anatomy, pattern of attack, and morphologies of wounds produced by particular animals can distinguish animal attacks from homicides, as well as attempt to identify the type of animal involved in an unwitnessed attack.

Sudden death due to leukostasis and lymphocyte thrombi in patients with chronic hematologic malignancies is rare. Leukostasis is characterized by highly elevated leukemic cell count and decreased tissue perfusion symptoms, leading to severe complications and even death. Chronic lymphocytic leukemia (CLL) is a chronic lymphoproliferative disorder that shows a highly heterogeneous clinical course, ranging from indolent form to very aggressive disease. Due to its low metabolic and mitotic rate, there is a lower incidence of clinically significant leukostasis in patients with CLL. Two main theories have been proposed in the development of leukostasis: (1) increased blood viscosity due to large leukemic cell populations; (2) high metabolic activity and cytokine production by leukemic cells. Both mechanisms lead to local hypoxic damage.We present a case of a 70-year-old man who died suddenly in the absence of symptoms. Autopsy and histology examinations revealed findings consistent with CLL and diffuse leukostasis involving the major organs' vessels.In the presence of gross and/or microscopic findings suggesting a potential hematologic malignancy, undiagnosed or relapsing hematologic malignancies should be considered in the differential diagnosis of sudden deaths.

The use of postmortem computed tomography (PMCT) to support autopsy pathology has increased in recent decades. To some extent, PMCT has also been contemplated as a potential alternative to conventional postmortem examination. The purpose of this study was to investigate the ability of PMCT to detect specific pathologic findings in the head and brain in natural hospital deaths.We examined postmortem CT images and autopsy data from 31 subjects who died at SUNY (State University of New York) Upstate University Hospital between 2013 and 2018. Each subject underwent a noncontrast PMCT and a traditional autopsy. A neuroradiologist analyzed PMCT images for head and brain abnormalities. The autopsies were performed by pathologists who were aware of the radiology results.In our series, PMCT was able to detect the majority of the significant space-occupying lesions, although it was not always reliable in ascertaining their nature. Postmortem computed tomography revealed findings usually challenging to detect at autopsy. Unfortunately, there were also situations in which PMCT was misleading, showing changes that were difficult to interpret, or that could be related to postmortem events. Therefore, we conclude PMCT should be used as an adjunct rather than a substitute to autopsy.

Pneumosinus Dilatans Frontalis (PDF) is a rare pathologic condition characterized by expansion and hyper aeration of the frontal sinuses. This abnormality has been described in otolaryngology, ophthalmology, neurology, and radiology journals, while only a few autopsy studies are reported in the English literature. The etiology of this condition remains unclear, although multiple theories have been proposed. Clinically, PDF is often an asymptomatic condition, but it can lead to significant bone deformation with esthetic complaints, and even severe associated neurological deficits. In the following case report, a 20-year-old Caucasian male committed suicide by asphyxia due to plastic bag suffocation combined with a vitiated atmosphere as a consequence of helium inhalation. At postmortem an abnormal expansion of the frontal sinuses was detected, involving the frontal bone just above the orbits. The defect showed a multiloculated appearance in the sinus cavities. An incidental diagnosis of PDF was made. A description of the findings and a hypothesis of the clinical relevance of PDF in the reported case are presented.

Intracranial pseudoaneurysm (IPA) is a rare but likely underdiagnosed cause of intracranial hemorrhage, which accounts for just 1-6% of all intracranial aneurysms. Spontaneous IPAs are exceptionally rare, and their etiology and features are not well defined. Herein, we report a case of a pediatric patient who died from massive intracranial bleeding due to the rupture of a spontaneous IPA after undergoing multiple radiological studies and neurosurgical operations. At the postmortem examination of the brain, a giant size pseudoaneurysm of the right middle cerebral artery was observed. Microscopic examination demonstrated variable wall thickness and dense fibrosis focally in the vessel wall with disruption of the media structure together with a loss and fragmentation of the elastic laminae, loss of organization of smooth muscle cells in the media, and multifocal areas of hemorrhage throughout the vessel wall, as well as direct evidence of wall dissection. Since IPAs without any traumatic or infective history are extremely uncommon, further pathologic studies should be performed to clarify spontaneous pseudoaneurysm etiology.

Skull fractures occur when forces striking the head exceed the mechanical integrity of the calvarium. A depressed skull fracture is a break in a cranial bone with depression of the bone into the brain. A depressed fracture may be open (compound), with a skin laceration over the fracture, or closed (simple), when the overlying tissue is not disrupted. The association between simple depressed fracture of the skull and elderly is rare. Paget disease of the bone is a chronic disease characterized by the deposition of abnormal bone tissue, more fragile than normal bone. We report a case of a 92-year-old man who was found supine on the floor in his residence, showing multiple signs of trauma. X-rays and computed tomography scans were performed, showing a simple depressed skull fracture on the right occipital-temporal area and even the characteristics of Paget disease of the skull. The first hypothesis was death due to voluntary homicide. A detailed study of clinical reports, laboratory tests, radiograph scans, and post mortem examination data allowed us to reconstruct the event. Death was finally ruled due to a mild passive trauma, suggesting the unlawful killing of a human without criminal intent, meaning involuntary manslaughter.

In the past, self-infliction of sharp force was a classic form of suicide, while in modern times it is quite rare, constituting only 2% to 3% of all self-inflicted deaths. In Japan, the jigai (Japanese characters: see text) ritual is a traditional method of female suicide, carried out by cutting the jugular vein using a knife called a tanto. The jigai ritual is the feminine counterpart of seppuku (well-known as harakiri), the ritual suicide of samurai warriors, which was carried out by a deep slash into the abdomen. In contrast to seppuku, jigai can be performed without assistance, which was fundamental for seppuku.The case we describe here involves an unusual case of suicide in which the victim was a male devotee of Japanese culture and weapons. He was found dead in his bathtub with a deep slash in the right lateral-cervical area, having cut only the internal jugular vein with a tanto knife, exactly as specified by the jigai ritual.

A 43-year-old Asian woman was found unresponsive on the sidewalk, prompting a call to 911. Upon transportation to the hospital, no signs of trauma were evident, but her condition deteriorated, leading to her eventual passing. An autopsy revealed a complete occlusion of the right coronary artery due to segmental coronary artery vasculitis. Without details of the individual's social or medical history, the specific type of coronary vasculitis couldn't be determined. The internal examination also showed thymic hyperplasia of unknown origin. While there is no conclusive evidence, a potential link between thymic hyperplasia, immune dysregulation, and coronary artery vasculitis is discussed, considering the case and existing literature.
