RESUMEN
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.

INTRODUCTION: Pheochromocytomas are rare catecholamine-producing neuroendocrine tumors. They are surgically curable but can be lethal if remain undiagnosed. We report a patient earlier diagnosed with malignant hyperthermia but later found to have pheochromocytoma on autopsy. CASE REPORT: After a preprocedural pain block for elective right shoulder arthroscopy, a 53-year-old hypertensive white man developed chest pain. In the operating room, he had increased blood pressure. Postoperatively, his blood pressures dropped from 220/100 to 80/30 mm Hg. He later developed high fever with core temperature reaching a peak of 42.2°C, rapid breathing, and died after unsuccessful attempts to stabilize him. AUTOPSY: Autopsy revealed a tumor in his right adrenal gland, measuring 10 cm in greatest dimension and weighing 530 g. It was red brown with a hemorrhagic and cystic cut surface. A thin rim of yellow-orange adrenal cortex was visible at the margin of the tumor, indicating that it originated from the underlying adrenal medulla. The left adrenal gland was unremarkable.Sections showed hypercellular tumor with zellballen architecture. The tumor cells were round to oval with finely granular basophilic cytoplasm and mild pleomorphism. A 24-hour urine sample collected before his death showed greater than 22727 µg/g Ratio to Creatinine metanephrines and normetanephrine, indicating that the tumor was active and secreted high levels of catecholamine. The cause of death was established as the complications of pheochromocytoma in the settings of general anesthesia for shoulder arthroscopy. The manner of death was natural. CONCLUSIONS: Pheochromocytoma can mimic malignant hyperthermia, and it should always be considered and managed appropriately in such scenarios to avoid untoward consequences. Pathologists must also be aware of this when conducting an autopsy in cases with a previous clinical diagnosis of malignant hyperthermia.

For more than 100 years since their initial description, gastric mucosal petechial hemorrhages have been discovered at autopsy in cases where environmental hypothermia was determined to be the cause of death. Although these lesions are frequently seen in deaths caused by environmental hypothermia, they can also be seen in cases where hypothermia is not implicated; however, this has been seldom described. We present a series of autopsy cases where hypothermia has been conclusively ruled out as a cause of death, in which Wischnewsky lesions are found. In all of these cases, diabetic ketoacidosis (DKA) was determined to be the proximate cause of death, as confirmed through clinical history, laboratory analysis, and absence of other anatomic or toxicological findings. We provide a mechanism of Wischnewsky lesion formation and how that mechanism relates to both hypothermia and ketoacidosis. Our data show that gastric mucosal petechial hemorrhages are not specific for hypothermia-related deaths, and are likely indicative of a state in which hypothermia and DKA have a common underlying pathophysiology, most likely a coagulopathy. Our data also illustrate that in autopsy cases where Wischnewsky lesions are found, DKA should be seriously considered as the underlying cause of death, particularly in the absence of indications of environmental hypothermia.

Dyskeratosis congenita (DC) is a genetic syndrome with progressive multisystem involvement classically characterized by the clinical triad of oral leukoplakia, nail dystrophy, and reticular hyperpigmentation. Frequent complications are bone marrow failure, increased rate of malignancy, lung and liver diseases. DC results from an anomalous progressive shortening of telomeres resulting in DNA replication problems inducing replicative senescence. We report a death due to DC in a 16-year-old male with bone marrow failure and multiple organ dysfunction. At autopsy, nail dystrophy and skin hypopigmentation were observed. Gross and microscopic examinations of the internal organs showed cardiac hypertrophy, multiple lung consolidations and prominent interstitial fibrosis, liver cirrhosis, and fibrosis. Multiple foci of extramedullary hematopoiesis were identified, including on the epidural surface of the dura, that is an infrequent location, mimicking a focal area of epidural hemorrhage. Only a few autopsy studies about DC are reported in the literature. Further research should be done to understand the pathophysiology of the disease and its complications.
RESUMEN
Introduction: Deaths due to drug overdose in the US in 2017 amounted to approximately 72,000, an increase of 12% from the previous year. There was a near tenfold increase in deaths involving synthetic opioids from 3,105 in 2013 to approximately 30,000 in 2017. Recent data from the United States (US) Centers for Disease Control and Prevention (CDC) identified fentanyl as most frequently involved in overdose deaths in the US as of 2016. This is consistent with statistics in New York State, where opioid-related overdose deaths increased by nearly 35% between 2015 and 2016, with fentanyl-related deaths increasing by 160%. The objective of this study is to report the incidence of deaths involving fentanyl and fentanyl analogs across five counties in Central New York between January 1, 2013 and December 17, 2017.Methods: All unintentional drug-related deaths across five counties in Central New York between January 1, 2013 and December 17, 2017 reported by the Medical Examiner's (ME) Office were included. Ante-mortem and post-mortem specimens were obtained for analysis.Results: A total of 417 deaths involving fentanyl and/or fentanyl analogs were reported, increasing from 10 cases in 2013 to 184 cases in 2017. Despropionyl fentanyl and furanylfentanyl were the analogs identified most frequently.Discussion: The study's data demonstrates an increase in the number of deaths related to fentanyl and/or fentanyl analogs. The number of deaths associated with fentanyl or an analog rose year to year, with despropionyl fentanyl and furanylfentanyl most commonly identified. The increase in fentanyl- and/or fentanyl analog-related deaths is consistent with national and international data.Conclusions: This study highlights the current crisis occurring in Central New York and serves to emphasize the ongoing global health threat posed by these chemical derivatives.

Several studies have shown an association between asthma and opiate abuse. This retrospective study aims to analyse the demographic, toxicological, and seasonal differences in asthmatic and non-asthmatic subjects who died of opiates. In addition, the relationship between toxicological levels of opiates and histologic grade of lung inflammation is examined. Deaths from 2013 to 2018 involving opiates as the primary cause of death in Cook County, Illinois (USA) were reviewed. Twenty-six cases of opiate deaths of individuals with a history of asthma and lung histology slides available were identified. In comparison, 40 cases of deaths due to opiates only were analysed. A check-list system for the evaluation of the grade of microscopic inflammation in asthma was developed. We found statistically significant differences between the asthmatics and the non-asthmatics regarding demography (age and race) and toxicology (6-MAM presence). In particular, the "opiate and asthma group" was mainly composed of African-American subjects, in contrast with the "opiate group", consisting mostly of Caucasian. The mean age was significantly higher in the "opiate and asthma group" compared with the "opiate group". A greater presence of 6-MAM was detected in the "opiate group" compared with the "opiate and asthma group". While we expected to find that low opiate levels would lead to deaths in asthmatics and, in particular, that lower opiate concentrations would cause deaths in subjects with higher grades of histologic inflammation, our study suggests that the quantity of drug and the level of inflammation are not statistically significant in the determination of death. We, therefore, recommend histologic examination of the lungs to evaluate for asthma, particularly in suspected low-level opiate-related deaths, to help further clarify any relationship between asthma and opiate use.

Atrial septal defects (ASDs) are one of the most prevalent congenital cardiac anomalies in adults. These interatrial communications can produce changes in the right heart (remodeling and failure) and the lungs (pulmonary hypertension). Most adults with ASDs are surgically treated with excellent results. However, a small fraction of patients is at risk for postoperative complications, particularly the persistence of pulmonary hypertension. A case of a 47-year-old woman who was found unresponsive in the bathroom of her house and died despite resuscitative efforts is described. According to medical records, the woman underwent a surgical repair of an atrial septal defect at the age of 37. At the autopsy, macroscopic and microscopic signs of advanced pulmonary hypertension were detected, highlighting the importance for the forensic pathologists to recognize pulmonary hypertension as a cause of sudden death in adults with a history of late surgical closure of an atrial septal defect.

BACKGROUND: Kratom is an herbal supplement containing alkaloids with opioid properties. This review was conducted to determine toxicities associated with kratom use in the United States in order to provide insight into its safety as a dietary supplement. METHODS: We conducted a retrospective review of kratom exposures reported to the National Poison Data System to determine the toxicities associated with kratom use. We also reviewed records from a county medical examiner's office in New York State to identify kratom-associated fatalities. RESULTS: A total of 2312 kratom exposures were reported, with 935 cases involving kratom as the only substance. Kratom most commonly caused agitation (18.6%), tachycardia (16.9%), drowsiness (13.6%), vomiting (11.2%), and confusion (8.1%). Serious effects of seizure (6.1%), withdrawal (6.1%), hallucinations (4.8%), respiratory depression (2.8%), coma (2.3%), and cardiac or respiratory arrest (0.6%) were also reported. Kratom was listed as a cause or contributing factor in the death of four decedents identified by the county medical examiner's office. CONCLUSIONS: Kratom use is increasing and is associated with significant toxicities. Our findings suggest kratom is not reasonably expected to be safe and poses a public health threat due to its availability as an herbal supplement.

The worldwide dependence on electricity to support the needs of today's society is often taken for granted and, as such, the hazards associated with the termination of electrical services are often neglected. Whether electrical services are unintentionally terminated as the result of severe weather or intentionally terminated as the result of nonpayment of utility bills, the ensuing conditions may lead to injury or death in affected individuals. We performed a retrospective review of all deaths investigated by the Onondaga County Medical Examiner's Office between 1999 and 2004. Our case database was searched for causes of death that included hypothermia, hyperthermia, carbon monoxide, fire, electrocution, and/or electricity. Further review of these cases was undertaken to determine the potential relationship between the death and the termination of electrical services. Seven fatalities were found to be associated with the termination of electrical services. Four fatalities resulted from its unintentional termination and 3 were a consequence of intentional termination. In reporting these deaths, we hope to emphasize the potential dangers associated with the termination of electrical services and explore the informational programs and public health laws that are in place to limit the associated potential negative outcomes.

Acute pancreatitis can present as sudden, expected death and, therefore, fall under the jurisdiction of the medical examiner/coroner (ME/C). Although its etiologies are varied, alcohol abuse, trauma, and drugs are important to consider in the forensic setting. It is therefore important for the forensic pathologist to have an understanding of these and other etiologies, to have a functional knowledge of the pancreatic anatomy and physiology, and to be able to diagnose acute pancreatitis and distinguish it from postmortem artifact. This review will highlight the forensic aspects of acute pancreatitis, with particular focus on acute hemorrhagic pancreatitis. This will include an overview of the developmental anatomy and normal physiology of the pancreas, the various causes of pancreatitis that may result in deaths coming to the attention of the ME/C, the underlying pathophysiology of the disease, the postmortem diagnosis of acute pancreatitis, and ancillary studies that support the diagnosis.

RESUMEN
We report a case of incidentally diagnosed chronic lymphocytic leukemia (CLL) in a patient with glioblastoma, which responded completely following standard treatment of the glioblastoma with temozolomide and cranial irradiation. The patient remained without an evidence of CLL until his death from recurrent glioblastoma. Further study of temozolomide for the treatment of CLL is indicated.
RESUMEN
Duloxetine is a second-generation selective serotonin and norepinephrine reuptake inhibitor used primarily for the treatment of depression. Relatively few fatalities have been reported in association with its use. Similarly, there are no known reports that provide a comprehensive analysis of blood, fluid and tissue samples in an overdose setting. Herein we present a fatal case of duloxetine toxicity with both the highest reported post-mortem blood concentration and a comprehensive toxicological analysis of duloxetine in femoral blood, vitreous humor, liver tissue, urine and gastric contents. In doing so, we hope to provide data that can assist both toxicologists and forensic pathologists with assessing duloxetine toxicity in the future.

Loeys-Dietz syndrome is a rare autosomal dominant connective tissue disorder with a genetic predisposition to aneurysm formation and congenital cardiofacial defects through genetic mutation affecting the transforming growth factor-beta (TGFß) signaling pathway. We present a case of a 6-year-old female patient with Loeys-Dietz syndrome who developed an annular aortic valve abscess and ascending aortic dissection due to Staphylococcus aureus endocarditis. Within this case, multiple complications from Loeys-Dietz syndrome were identified, including prosthetic valve infection, aneurysm formation and dissection, septic embolism, and aspiration pneumonia. The clinical presentation, pathologic findings, and pathophysiology will be discussed.
RESUMEN
Adverse effects associated with synthetic cannabinoid use include agitation, psychosis, seizures and cardiovascular effects, all which may result in a lethal outcome. We report the collection of data from 25 medical examiner and coroner cases where the presence of synthetic cannabinoids was analytically determined. Participating offices provided case history, investigative and relevant autopsy findings and toxicology results along with the cause and manner of death determination. This information, with the agency and cause and manner of death determinations blinded, was sent to participants. Participants offered their opinions regarding the likely contribution of the toxicology findings to cause and manner of death. The results show that some deaths are being attributed to synthetic cannabinoids, with the highest risk areas being behavioral toxicity resulting in excited delirium, trauma or accidents and as contributing factors in subjects with pre-existing cardiopulmonary disease. While insufficient information exists to correlate blood synthetic cannabinoid concentrations to effect, in the absence of other reasonable causes, the drugs should be considered as a cause or contributory cause of death based on history and circumstances with supporting toxicological data.

Malaria is the world's most important parasitic disease, accounting for an estimated 300 to 500 million new cases and between 1.5 and 2.7 deaths annually. The majority of these deaths occur in sub-Saharan Africa where malaria is endemic and are the result of infection with Plasmodium falciparum. The number of deaths in the United States due to malaria is comparably much lower and involves so-called "imported" cases in which U.S. travelers acquire the infection upon travel to endemic areas and subsequently return to the United States or in which infected foreign citizens travel to the United States. There were a total of 118 deaths due to malaria in the United States between 1979 and 1998 with an average of 5.9 deaths per year. Specific epidemiological data provided by the CDC regarding the 40 deaths that occurred between 1992 and 1998 yielded the following results. Deaths occurred in patients ranging from 9 months to 89 years of age (median, 53 years). Thirty-eight (95%) of these were due to P. falciparum and two (5%) due to P. vivax. Anti-malarial chemoprophylaxis was taken in 40% of cases, not taken in 45% of cases, and unknown in 15% of cases. Twenty-four (60%) of the cases involved U.S. travelers to endemic areas, of whom 59% traveled to Africa, 25% to South America, 8% to India, 4% to Haiti, and 4% to unspecified areas. The remaining cases included eleven foreign travelers to the U.S. (27.5%), three induced cases (7.5%), and two undetermined cases (5%). Thirty-nine (98%) of the cases were diagnosed antemortem and only one case was known to have come to the attention of the medical examiner/coroner. An illustrative case report demonstrates many of the features associated with fatal malaria infections in the United States. The case involves a U.S. student who was studying in Africa and who, by report, had not taken antimalarial chemoprophylaxis. Despite seeking medical attention, the patient was not diagnosed with P. falciparum infection and cerebral malaria until the time of medico-legal autopsy, where the classic gross and microscopic features of cerebral malaria were identified. This case represents one of the few cases of P. falciparum infection in the United States not diagnosed antemortem. Given the worldwide prevalence of the disease, increasing international travel, and rapidly developing drug resistance, malaria will continue to be an important disease and should be considered in cases of sudden, unexplained deaths. By reviewing the major epidemiological features of malaria-related deaths in the United States and by presenting the major gross and microscopic features of cerebral malaria, an attempt is made at raising the awareness of the forensic community to the potential of malaria-related deaths.

The Combitube is a ventilatory device consisting of a twin lumen tube with proximal and distal inflatable cuffs. The major benefit of the Combitube is that its design and function allow for ventilation through non-laryngoscope-assisted insertion into either the trachea, or esophagus. As with any invasive procedure, intubation using the Combitube carries certain risks and potential complications. The majority of complications are relatively minor; however, a rare and serious complication reported primarily in the anesthesiology literature is laceration of the esophagus. This reportedly rare injury is increasingly seen by medical examiners/coroners in the forensic setting. This paper presents a series of three cases of esophageal laceration and a single case of perforation of the hypopharynx associated with the use of the Combitube, while also exploring potential mechanisms of injury. In addition, this work demonstrates the vital role the medical examiner/coroner plays in identifying existing or potential problems with current or emerging medical devices.
