The association between earlobe crease(s) and coronary artery atherosclerosis has stimulated debate and controversy over the years. Most available published studies have been conducted on living patients. Although these studies offer valuable insight into such associations in patients who exhibit symptoms, no information is available from these studies on the prevalence of earlobe creases among an asymptomatic population. Postmortem studies offer the advantage of including individuals free of symptomatic cardiovascular disease, thus providing an inbuilt control group. The atherosclerotic pathological findings of 1298 individuals who underwent coronial postmortem examination at Wellington Regional Hospital, New Zealand, between 2006 and 2013 were retrospectively studied. Earlobe creases and atherosclerosis involving the coronary arteries were semiquantitatively appraised. The presence of an earlobe crease was found to be significantly associated with coronary artery atherosclerosis.

The definition of myocardial infarction (MI) type 3 does not include the possible elevation of postmortem biomarkers if measured at autopsy. We determined postmortem cardiac troponin I (cTnI) levels in plasma samples obtained at autopsy in patients who died from MI type 3 to determine whether cTnI plasma levels may be elevated.
Using a chemiluminescent microparticle immunoassay system, we determined postmortem cTnI plasma levels at autopsy performed within 24 hours of death in every decedent who died from MI type 3, confirmed by an autopsy. Over 2 years, autopsy confirmed 52 decedents who died from MI type 3 due to coronary atherosclerotic disease. The age range and mean age were 40 to 78 and 60.6 years, respectively, 38 (73%) men and 14 (27%) women. Ten percent of the decedents exhibited postmortem cTnI plasma levels that were within the normal reference levels (0.01-0.30 ng/mL). Ninety percent of the decedents exhibited elevated cTnI plasma levels at autopsy, which ranged from 0.31 to greater than 4400 ng/mL. link2 Sixty-nine percent of our decedents showed severe/significant (75%-100%) luminal occlusion in 2 or 3 major coronary arteries.
If cTnI plasma levels are measured in autopsy blood samples after sudden and unexpected death due to MI type 3, highly elevated cTnI plasma levels may be detected. We propose that the current MI type 3 definition be slightly modified to include the possible elevation of cTnI plasma levels if measured at autopsy in the immediate postmortem period.

The diagnosis homicide by unspecified means (HUM) is used to categorize deaths occurring under suspicious or criminal circumstances, but a specific cause of death cannot be identified. In 2010, Matshes and Lew (Am J Forensic Med Pathol. 2010;31(2)174-177) presented a HUM cases series, from which they derived 5 diagnostic criteria; however, the accuracy of these criteria has not been assessed.To identify a validation cohort, Cuyahoga County Medical Examiner's Office records were searched from 2008 to 2019 for cases certified as HUM. Thirteen cases were identified; on review, all cases fulfilled criteria 1, 4, and 5. Only 1 case had a potential anatomic cause of death identified (criterion 2).However, in 3 cases, toxicologic analyses could not be conducted because of skeletonization; in 2 cases, the decedents tested positive for cocaine/benzoylecgonine but were found in proximity to other victims for whom a specific violent cause of death was determined. link3 By strict reading of criterion 3, these cases would havn 2).However, in 3 cases, toxicologic analyses could not be conducted because of skeletonization; in 2 cases, the decedents tested positive for cocaine/benzoylecgonine but were found in proximity to other victims for whom a specific violent cause of death was determined. By strict reading of criterion 3, these cases would have been excluded from the diagnosis of HUM. Perpetrators confessed to homicide in 7 cases, including the 5 cases that failed the toxicologic criterion. The 2010 diagnostic criteria are a reasonable foundation for the determination of HUM; modification of criterion 3 would provide improved flexibility based on clinical judgment.
Glyphosate is an organophosphorus compound and the active ingredient in commonly used herbicides, whereas polyoxyethyleneamine (POEA) is a nonionic surfactant often coupled with glyphosate in these herbicides to increase their efficacy. Cases of glyphosate-POEA ingestion have shown a variety of outcomes, ranging from skin and mucosal surface irritation to death. Here, we report mortality after ingestion of at least 237 mL of an herbicide confirmed to contain both glyphosate and POEA. The decedent's electronic medical record indicates presentation to the emergency department shortly after ingestion and rapid decompensation, with death occurring on the fourth day of admission. The autopsy report showed extensive pulmonary edema and congestion with no alimentary tract abnormalities. Microscopically, airway inflammation, edema, and hemorrhage were shown as well as pericentral necrosis and macrovascular hepatic steatosis. This case is unusual for several reasons including the fatal outcome in a young 30-year-old decompensation, with death occurring on the fourth day of admission. The autopsy report showed extensive pulmonary edema and congestion with no alimentary tract abnormalities. Microscopically, airway inflammation, edema, and hemorrhage were shown as well as pericentral necrosis and macrovascular hepatic steatosis. This case is unusual for several reasons including the fatal outcome in a young 30-year-old patient, the large volume of the herbicide consumed, the associated large volume aspirated, and the lung pathology associated with exposure to glyphosate-POEA since inhalation, and in this case, aspiration is an uncommon route of glyphosate-POEA exposure. This report therefore offers rare respiratory tract pathological findings and the clinical course after aspiration of a large volume of glyphosate-POEA.
This survey of Canadian pathology residents was designed to quantify the number of autopsies Canadian residents aim to complete during residency training, to better understand the perception of residents about access and quality of autopsy skills education. In addition, the interest of current pathology residents in autopsy and forensic pathology as a future career was also assessed.
A web-based survey was sent to all Canadian pathology residents. This survey consisted of 19 questions on institution, level of training, intention to complete the American Board of Pathology examination, number of autopsies completed, perception of quality/access to autopsy skills education, interest, and factors contributing to autopsy and forensic pathology.
Eighty two (26%) of a possible 310 residents (12/47 general pathology, 70/263 anatomical pathology) across all Canadian institutions offering anatomical or general pathology programs (16/16 institutions) participated in the survey. Eighty-three percent of the respondgood job market in comparison with most other subspecialties.
Forensic pathologists may sometimes encounter cases of suicide with ingestion of unusual compounds. Herein, we describe a case of suicide by ingestion of barium acetate. Deaths by ingestion of this compound have not previously been reported in literature. This case shows the clinical presentation of the toxicity of barium compounds and highlights the importance of scene investigation and clinicopathologic correlation in suicides by unusual ingestion.

Muscular hemorrhages around the scapula that are caused by upper extremity motion are rarely reported in cases other than drowning. We examined differences in the frequency of muscular hemorrhages around the scapula and stratified them by the cause of death. Muscular hemorrhages were mostly noted in cases of drowning (118/185, 63.8%), followed by cases of asphyxia (23/44, 52.3%). In addition, muscular hemorrhages around the scapula were found in cases of ligature strangulation (8/11, 72.7%), manual strangulation (2/3, 66.7%), choking (11/14, 78.6%), and traumatic asphyxia (2/2, 100%). Muscular hemorrhages were not found in cases of hanging or environmental suffocation, possibly because of the short time interval preceding the loss of consciousness. The distribution of muscular hemorrhages was similar in choking and drowning cases. Muscular hemorrhages due to strangulation were mainly unilateral, whereas those due to choking and drowning were mainly bilateral. During all types of asphyxia, muscular hemorrhages around the scapula were considered to be the result of conscious, active upper extremity motion.
