RESUMO
To differentiate between medical malpractice and expected, but rare, medical complication in a medicolegal autopsy context is often difficult. Such an assessment requires knowledge about the clinical practice associated with the procedure at hand, and that findings of the autopsy, including medical relevant information such as patient chart, radiological imaging, and statements from witnesses about the medical procedure itself, provides evidence that substantiate either conclusion. In a case report published in the journal such an assessment is discussed by presenting findings and circumstances surrounding the death of a patient during a percutaneous needle lung biopsy procedure. The authors conclude that the death was not due to medical malpractice. However, in this commentary it is highlighted that the reasoning behind the conclusion needs to be further substantiated.

BACKGROUND: Nonischemic heart disease (NIHD) is the underlying pathology in about 20% of sudden cardiac deaths (SCDs). Psychotropic medication has been reported as a risk factor for SCD among patients with coronary artery disease, but similar information concerning NIHD is scarce. OBJECTIVES: We evaluated the use of psychotropic medication in victims of SCD due to NIHD and compared it to the general medication use in Finland. METHOD: Study population was derived from the Finnish Genetic Study of Arrhythmic Events (Fingesture) (n = 5,869, mean age: 65 ± 12, 79% males; 1,404 victims of SCD due to NIHD, mean age: 57 ± 13, 77% males). All deaths occurred in Northern Finland during 1998-2017. All victims underwent a medicolegal autopsy. Data on use of medication were defined using postmortem toxicology results and patient records. Subjects with neither toxicological analysis nor information of medication use available were excluded. Information on general medication use was derived from Finnish Statistics on Medicines 2018 and presented as defined daily dose/1,000 inhabitants/day. RESULTS: Psychotropic medication was used by 579 (41%) subjects with NIHD, whereas in the general population, only 12% were estimated to use psychotropics. The results were similar in subgroups of psychotropic medication: 27% versus 2.3% for benzodiazepines, 19% versus 7.5% for antidepressants, and 18% versus 2.2% for antipsychotics. CONCLUSIONS: Use of psychotropic medication is common in victims of SCD due to NIHD compared to the general population.

The use of animals for therapeutic purposes is based on traditional beliefs, family pressure, and watching others appear to be cured. We report an unusual case of a 47-y-old man who choked to death after consuming a live slug. During autopsy, a 9.5-cm slug was found impacted in the tracheobronchial tree. History provided by the family revealed that the deceased consumed slugs in the belief that this would relieve his symptoms of chronic arthritis. We report this rare case to highlight the possible ill effects of such practices.

Placenta percreta is a rare, aggressive, and severe form of the placenta accreta spectrum. One of its most devastating effects is the sudden rupture of uterus. Uterine scarring is the leading risk factor for uterine rupture, although it can also happen, but rarely, in an unscarred uterus showing more severe repercussions. The present study reported a case of an Egyptian primigravida female, aged 29 years old, at 32 weeks of gestation who died suddenly due to uterine rupture complicating placenta percreta, the diagnosis of which was first settled during autopsy. There was no history of abdominal trauma. No medical history of significance was present. Autopsy denoted an intrauterine fetal death of 32 weeks gestational age. The fundus of the uterus had a laceration (rupture) of the uterine wall including the serosa and myometrium. The placenta has extensively infiltrated the fundus uterine wall and penetrated the myometrium and serosa. Histopathological examination of the ruptured site on the uterus confirms total invasion of the uterine wall by chorionic villi with the presence of hemorrhage and fibrin indicating placenta percreta. Uterine rupture due to placenta percreta may go unnoticed, especially when no associated high-risk factors exist. The current case depicts that placenta percreta is a rare but critical complication of pregnancy that may exist at any stage of pregnancy without any associated high-risk factors with unusual symptoms and leads to uterine rupture and sudden death.
RESUMO
BACKGROUND: Although the mean age of sudden cardiac death (SCD) victims has increased during recent decades, overall incidence has remained relatively stable. Small but very important proportion of SCDs occur in subjects under 40 years of age and temporal trends in the incidence and characteristics of SCD in this age-group are not well known. METHODS: The Fingesture study has prospectively gathered data from 5,869 consecutive autopsy verified SCD victims in Northern Finland during 1998-2017. On the basis of Finnish law, all who die unexpectedly undergo autopsy. RESULTS: Out of total 5,869 SCDs, 160 occurred in subjects under 40 years of age (3%) indicating a total incidence of 2.9/100,000/year. Incidence decreased during the study period: 4.0/100,000/year (n = 50) in 1998-2002, 3.7/100,000/year (n = 45) in 2003-2007, 2.5/100,000/year (n = 36) in 2008-2012, and 1.5/100,000/year (n = 29) in 2013-2017. Coronary artery disease (CAD) was the cause of death in 46 SCD victims (29%). Among nonischemic causes, most common were obesity-related hypertrophic myocardial disease (24%), primary myocardial fibrosis (19%), and hypertensive myocardial disease (6%). The incidence of SCD caused by CAD decreased as follows: 1.5/100,000/year in 1998-2002, 1.2/100,000/year in 2003-2007, 0.6/100,000/year in 2008-2012, and 0.2/100,000/year in 2013-2017. Proportion of male gender (81%) and obesity as a comorbidity (body mass index >30 kg/m2, 40%) remained relatively stable during the period (p = 0.58 and p = 0.79, respectively). CONCLUSIONS: The incidence of SCD in subjects under 40 years of age has decreased in Northern Finland during 1998-2017. According to autopsy data, most of the deaths are due to nonischemic myocardial diseases and relative proportion of CAD has decreased.

CoVID-19 is a novel viral infection with now well-established clinical radiological findings. There is limited data on post-mortem imaging. We explore the proposition that PMCT could be used as screening test. In an 11-week period, 39 deceased persons were referred for medicolegal investigation with pre-existing or subsequent nasopharyngeal swabs showing positivity on SARS-CoV-2 RT-PCR testing. All 39 had routine whole-body CT scans on admission and 12 underwent medicolegal autopsy. These cases were contrasted with 4 others which were negative on nasopharyngeal swabs despite PMCT findings suggestive of CoVID-19 pneumonia (designated false positive). Nine of the 12 autopsies showed lung histology consistent with those reported in CoVID-19 pneumonia. Typical clinical CoVID-19 lung findings on PMCT were only detected in 5 (42%). In 3 of the 4 false positive cases, lung findings showed non-COVID-19 histology but in 1, findings were identical. PMCT CoVID-19 findings in the lungs are therefore not specific and may not be detected in all cases due to obscuration by expected agonal CT findings or other pathologies that pre-dated SARS-CoV-2 infection. PMCT findings may otherwise be subtle. Although PMCT may hint at CoVID-19, we believe that nasopharyngeal swabs are still required for definitive diagnosis. Even with positive swabs, clinical CoVID-19 lung findings on PMCT are often not detected. PMCT findings can be subtle, extreme or obscured by agonal changes. Given this range of PMCT changes, the challenge for pathologists is to determine whether death has been caused by, or merely associated with, SARS-CoV-2 infection.

BACKGROUND: There are no detailed reports, in terms of epidemiology and pathology, on intracranial aneurysms and on dissections that were found in unexpected fatal subarachnoid hemorrhage (SAH) cases. In this report we analyzed, based on large-sized medicolegal autopsy cases, the detailed epidemiology and pathological aspects of both lesions. METHODS: We analyzed 607 autopsy cases of unexpected fatal SAHs including 496 aneurysms and 111 dissections. RESULTS: The following results were obtained: (1) Patients who died of dissections were younger than those who died of aneurysms; (2) symptom prevalence rates of aneurysms were 31.9%, appearing to be lower than those in previous studies; (3) a significantly higher prevalence of clinical symptoms was found in patients with dissections (60.5%) than patients with aneurysms; (4) hypertensive cardiomegaly was indicated in more than 80%, while no obvious difference in incidence in hypertensive cardiomegaly was noted between aneurysms and dissections; (5) aneurysms were found to occur much more frequently in the anterior communicating artery (31.9%) and vertebral arteries (7.5%), while dissections were found much more commonly in vertebral arteries (93.7%); and (6) the size of aneurysms was much smaller in general than that previously regarded as a risk factor of rupturing. CONCLUSIONS: These data might help in the prompt intervention in SAH and also in the prevention of lethal SAH in clinical settings.

INTRODUCTION: In medicolegal practice, rare cases associated with suicidal, criminal or accidental overdose of insulin are both analytically and forensically challenging. The determination of insulin in post-mortem blood has limited diagnostic value, mainly on account of post-mortem chemical degradation processes (particularly hemolysis), and hence is not useful in medicolegal practice. AIM OF THE STUDY: The aims of the study were: 1) to assess the usefulness of the immunoradiometric method, used in clinical practice, for post-mortem measurement of insulin concentration in the intraocular fluid, 2) to preliminarily evaluate the usefulness of the obtained results for toxicological and medicolegal assessment, and 3) to verify on the basis of our own material the validity of the cited literature data on the effect of hemolysis on the result of insulin level determination in post-mortem blood. MATERIAL AND METHODS: The study material consisted of 93 samples of intraocular fluid collected during consecutive medicolegal autopsies performed in the Department of Forensic Medicine and Forensic Toxicology, Medical University of Silesia in Katowice. In addition, 10 samples of peripheral blood taken from living people (5 women and 5 men) for clinical and diagnostic purposes were analyzed. Insulin(e) IRMA KIT from IMMUNOTECH was used for the analyses. RESULTS: In 86 (92.5%) samples, the insulin concentration was below the analytical sensitivity of the method (less than 0.5 µIU/ml), while in 7 cases it was in the range of 1.42-24.42 µIU/ml. CONCLUSIONS: Determination of the insulin level in the intraocular fluid by the immunoradiometric method provides an opportunity for objective verification of poisoning, however this claim requires further research.

Part 2 of the review "Back to the Future" is dedicated to the evolutionary role of the bio-medicolegal sciences, reporting the historical profiles, the state of the art, and prospects for future development of the main related techniques and methods of the ancillary disciplines that have risen to the role of "autonomous" sciences, namely, Genetics and Genomics, Toxicology, Radiology, and Imaging, involved in historic synergy in the "post-mortem assessment," together with the mother discipline Legal Medicine, by way of its primary fundament, universally denominated as Forensic Pathology. The evolution of the scientific research and the increased accuracy of the various disciplines will be oriented towards the elaboration of an "algorithm," able to weigh the value of "evidence" placed at the disposal of the "justice system" as real truth and proof.

Neurocysticercosis is endemic in many parts of the underdeveloped and developing countries, with continuous presence in developed countries due to the influx of migrants from regions where the diseases are endemic. Neuroimaging, anatomic pathological techniques, immunodiagnostic tests, clinical examination and epidemiologic considerations will easily provide the diagnosis. However, physicians in developed countries are perhaps progressively missing the diagnosis, and need to re-acquaint themselves with the condition and acquire a high suspicion index. The authors present a medicolegal case where the forensic team made a conclusion of neurocysticercosis (among other diagnoses), following post mortem examination of a largely skeletonized and mummified human remains. Characteristic changes were observed in the calvarium of the decedent at autopsy. Review of the antemortem medical records revealed that Computed Tomography (CT) scan had 12 years earlier, suggested diagnostic features in a Hispanic migrant, but the attending surgeons failed to consider the possibility of the condition. Physicians should pay attention to suggestive clinical findings especially when attending to individuals coming from endemic parts of the world. Cysticercosis remains endemic and a misdiagnosis can potentially attract medical malpractice suits. Forensic pathologists should also consider the possibility of uncommon clinical disorders, even in skeletonized remains. Perhaps an earlier diagnosis might have altered the outcome in the decedent.

Primary myocardial fibrosis (PMF), defined as myocardial fibrosis in the absence of identifiable causes, may represent a common alternative phenotype in various cardiomyopathies and contribute to sudden cardiac death (SCD). No previous definitions of histopathological characteristics exist for PMF. We aimed to evaluate whether common features of fibrosis could be identified. PMF cases (n = 28) were selected from the FinGesture cohort consisting of 5,869 SCD victims that underwent a medicolegal autopsy. Twelve trauma controls and 10 ischemic heart disease cases were selected as reference groups. Further 3 PMF cases and 5 ischemic heart disease cases from autopsies performed in the University of Copenhagen, Denmark, were selected for a validation substudy. Relative area of fibrosis, amount of diffuse and perivascular fibrosis, and location of fibrosis were assessed from left ventricle myocardial samples stained with Masson trichrome. Further evaluations were performed with alpha-smooth muscle actin (α-SMA), vimentin, and CD68 stainings. Mean relative area of fibrosis was 5.8 ± 10.7%, 1.0 ± 0.7%, and 7.0 ± 7.4% in PMF, trauma controls, and ischemic cases, respectively. Fibrosis in the PMF group was mostly located in other sites than the endocardium. Most cases with fibrosis had vimentin-positive but α-SMA-negative stromal cells within fibrotic areas. Histopathologically, PMF represents a heterogeneous entity with variable fibrotic lesions affecting the whole myocardium and a suggested significant role of fibroblasts. These findings may bring validation to PMF being a common manifestation of cardiomyopathies. Evidently, PMF stands out as a particular entity demanding special attention as a cause of SCD.
RESUMO
The predominance of artificial intelligence (AI) will be the next Industrial Revolution. All the fields of industry will be reshaped with AI. Forensic medicine and toxicology is an important branch for investigations of crimes and this branch has tremendous scope of development with the help of AI. Any science or process cannot stay away long from newer techniques. The traditional way of doing an autopsy and framing an opinion has a lot of limitations and these limitations can be overcome with AI. Various procedures of forensic medicine like analysis of toxins, collection of the various samples of medicolegal importance from body cavity, detection of pathological changes in various organs of the body, detection of various stains on the body, detection of a weapon used in crime, time since death calculations, etc. are the areas where AI will play a key role in framing the various opinions of medicolegal importance. AI can also be integrated into existing testing and analysis processes to make the whole procedure rapid and more accurate. In the future, AI might become a key part of forensic medicine and toxicology practice.
RESUMO
The mouth plays an important role in the self-representation and its damage threatens psychological integrity and self-perception. There is literature that reports the mouth as an intentional source of harm in different contexts of violence and torture. Mutilations in drug trafficking contexts (as "corpse messaging") have been recommended as necessary for evaluation and analysis in medicolegal environment as they can guide investigations, even favoring the identification of the criminal group involved. A scoping review focused on lesions and oral signs configuring oral corpse messaging in victims of drug trafficking was carried out, which identified six patterns: a) genitals stuffed in the mouth; b) finger stuffed in mouth; c) 'Colombian necktie'; d) cutting out the tongue; e) the mouth is taped shut; and f) badges stuffed into the mouths. The meanings attributed to each of these oral corpse messaging, their historical contexts, and their diagnostic value in the drug trafficking scene in Latin America are discussed. The role that the forensic dentist can play during the medicolegal autopsy is also discussed.

Objective: This study aimed to determine the clinicopathological characteristics of cancer-associated venous thromboembolism (CAT-VTE). Methods: A total of 47 cases of lethal pulmonary thromboembolism (PTE) with active cancer were investigated by autopsy records. Results: We studied 22 men and 25 women who were deceased at a mean age of 66±11 years. Nine (19%) patients had recently undergone cancer resection, 14 (30%) were undergoing clinical treatment for cancer, and 24 (51%) were autopsy-proven CAT-VTE. The colon (eight cases), lungs (seven cases), and ovaries (six cases) were frequent sites of a tumor. There were 29 (62%) cases of acute PTE and 18 (38%) of recurrent PTE. The embolic source was detected in 36/39 (92%) cases. Among them, 33 cases were leg deep vein thrombosis (DVT) and 31 were calf-type DVT. Three cases were isolated vena cava thrombi that were present near the tumor. Twenty-three (64%) cases were recurrent DVT. Conclusion: Most of the lethal CAT-VTE cases were induced by the same mechanism as non-CAT-VTE that originated from calf-type DVT with proximal propagation. However, the finding that patients had tumor-related vena cava thrombi suggested that prevention of CAT-VTE requires individualized treatment of patients according to their pathological condition. (This is secondary publication from Jpn J Phlebol 2020; 31(3): 123-129.).
RESUMO
To this day, autopsies and dissections have been essential in medical education, but declining autopsy numbers have endangered this long-standing tradition. Students' perceptions of these teaching methods should be constantly updated to help educators understand how to achieve their teaching goals. The purpose of this study was to explore the state of autopsy- and dissection-based teaching in two Finnish universities based on the experiences of the students, survey their perceptions of such teaching, and to compare the Finnish situation with students' perceptions in other countries as it emerges from medical literature. A questionnaire went to 859 second-, fourth-, and sixth-year medical students. The questions concerned dissection and autopsy classes these students had attended, the views of the students in regard to the number of classes, and the benefits of and attitudes towards autopsy teaching. An open question of how to improve autopsy teaching was included. The response rate was 19.4%. Most respondents requested more autopsy and dissection classes, especially practical education. They found autopsies most beneficial in learning anatomy and dealing with one's own emotions related to death. Their experiences proved least beneficial for interaction with the relatives of a deceased patient and for people skills. Integrational methods and focusing on the main learning outcomes were suggested as improvements. Overall, students found dissection and autopsy teaching important, but felt concerned about the diminishing autopsy numbers. Focusing on main learning objectives and better integration of autopsies in the teaching of different specialties could help to utilize autopsies to a greater extent.

Objective: Cardiac hypertrophy with varying degrees of myocardial fibrosis is commonly associated with coronary artery disease (CAD) related sudden cardiac death (SCD), especially in young victims among whom patterns of coronary artery lesions do not entirely appear to explain the cause of SCD. Our aim was to study the genetic background of hypertrophy, with or without fibrosis, among ischemic SCD victims with single vessel CAD. Methods: The study population was derived from the Fingesture study, consisting of all autopsy-verified SCDs in Northern Finland between the years 1998 and 2017 (n = 5,869). We carried out targeted next-generation sequencing using a panel of 174 genes associated with myocardial structure and ion channel function in 95 ischemic-SCD victims (mean age 63.6 ± 10.3 years; 88.4% males) with single-vessel CAD in the absence of previously diagnosed CAD and cardiac hypertrophy with or without myocardial fibrosis at autopsy. Results: A total of 42 rare variants were detected in 43 subjects (45.3% of the study subjects). Five variants in eight subjects (8.4%) were classified as pathogenic or likely pathogenic. We observed 37 variants of uncertain significance in 39 subjects (40.6%). Variants were detected in myocardial structure protein coding genes, associated with arrhythmogenic right ventricular, dilated, hypertrophic and left ventricular non-compaction cardiomyopathies. Also, variants were detected in ryanodine receptor 2 (RYR2), a gene associated with both cardiomyopathies and catecholaminergic polymorphic ventricular tachycardias. Conclusions: Rare variants associated with cardiomyopathies, in the absence of anatomic evidence of the specific inherited cardiomyopathies, were common findings among CAD-related SCD victims with single vessel disease and myocardial hypertrophy found at autopsies, suggesting that these variants may modulate the risk for fatal arrhythmias and SCD in ischemic disease.
RESUMO
A Japanese woman in her 30s was found dead on a mattress. She had had fever, cough, and dyspnea for about 2â¯weeks. Gross examination at autopsy revealed slight enlargement of the thyroid gland and histopathological examination resulted in a diagnosis of chronic lymphocytic thyroiditis. The concentration of triiodothyronine in the cadaveric blood was extraordinarily high, whereas that of thyroid stimulating hormone was below the detection limit. Autoimmune antibodies against thyroid tissue were positive. The cause of death was assumed to be congestive heart failure caused by thyroid storm associated with chronic lymphocytic thyroiditis. Systemic histopathological examination of tissues and postmortem biochemistry can enable a diagnosis in medicolegal autopsies.
RESUMO
We present the first report of pneumopericardium observed by autopsy and on postmortem computed tomography (PMCT) images. The subject was a woman who died of self-inflicted stab wounds to the abdomen. The PMCT scan revealed air in the pericardial sac, a "flattened heart" sign, and retroperitoneal hemorrhage. Medicolegal autopsy revealed two abdominal stab wounds near the xiphoid process that had cut the apical pericardium and adjacent diaphragm and liver. Examination of the open thorax confirmed that the pericardial sac was distended with air. The wound extended to the abdominal aorta, causing retroperitoneal hemorrhage. PMCT images showed that the pneumopericardial volume was 133 mL. We believe that cardiac tamponade occurred resulting from the tension pneumopericardium; however, the effects were mitigated by hypovolemia secondary to the retroperitoneal hemorrhage as well as obstructive shock. Therefore, the cause of death appears to have been low-pressure cardiac tamponade.

The aim of postmortem medicolegal examination in pediatric death is primarily to establish the circumstances and causes of death and to exclude child abuse. In France, pediatric death is systematically documented by medicolegal or medical autopsy. In case of medicolegal autopsy, the complementary examinations, requested and financed by justice, are rarely limited to a histopathological examination. However in medical autopsies other tools are available to the pathologist as toxicology, biochemistry and molecular biology. The purpose of this article is to evaluate the efficacy of forensic histopathology in pediatric forensic autopsies. We analyze the main causes of pediatric death in a forensic context. Between 2004 and 2015, 157 infant deaths were identified in Marseille university hospital. The forensic histopathology and autopsy reports of all 157 cases were available for systematic review. Medical or surgical causes represented 41,3% of deaths in our center, accidental causes 8.1% and child abuse 28,8%. The definitive diagnosis was made at autopsy in 30% of cases and at histopathological examination in 70% highlighting that forensic histopathology is an indispensable tool in pediatric medicolegal autopsies. Significant histological abnormalities may be detected in selected organs such as the brain, lungs, heart, liver, adrenal glands and kidneys in spite of macroscopically normal appearances. This justifies systematic sampling of all organs. Despite the implementation of the French sudden infant death protocol which recommends medical autopsies, too many pediatric autopsies are carried out in a medicolegal context. 30% of the cases remain without diagnosis at the end of the autopsy and histological examination. This number could be reduced by the contribution of others laboratory investigation.

INTRODUCTION: Autopsies are carried out to establish the identity, cause of death, time of death, and ante-mortem or post-mortem nature of death. These help in establishing the cause of death and ascertain the disease process which led to death. AIM: To study the prevalence and pattern of lung diseases in medicolegal autopsies, confirmed by histopathological examination. MATERIALS AND METHODS: This retrospective study was carried out in the Department of Pathology. Tissue bits from lungs, retrieved at the time of autopsy, were preserved in 10% formalin. These were processed and examined microscopically. A total of 86 cases were received during the period of study. RESULTS: Among these 86 cases, in 4 cases (4.8%) the tissue was autolysed and in another 26 cases (30.1%) histopathology was unremarkable. Significant microscopic findings were found in 56 cases (65.1%). Wide spectrum of microscopic findings were seen, the commonest being oedema and congestion (28.5%) followed by changes in interstitium (11.9%). There were 9.5% cases of granulomatous inflammation and 5.9% cases each of acute pneumonia and emphysema. There were 1.2% cases each of Hyaline Membrane Disease (HMD), Meconium Aspiration Syndrome (MAS) and Acute Respiratory Distress Syndrome (ARDS) in the series. The series also had 1.2% cases of young adult having fungal colonies surrounded by necrosis and abscess formation. Possibility of mucormycosis was suggested in that case. CONCLUSION: This study highlights various lesions in lungs confirmed by histopathology, which were either incidental or direct cause of death. The short coming in present study was non receipt of whole organ or representative sample at the time of autopsy, which if overcome will set much higher standard of autopsy reporting and would be a more useful tool in understanding cause of death.
