RESUMO
Physical restraint is usually used when trying to control and terminate a violent episode. Many causes are possible behind aggressive, agitated, and violent behavior. Some of these are such factors that can either be detected in forensic autopsies or can be evident from the person's medical records. Various causes for deaths during physical restraint have been suggested. In this study, we wanted to review all incidents in which physical restraint was employed, ending in death of the restrained person, whether the restraint was applied by police officers, security guards, police custody personnel, health care personnel or ordinary civilians. The main aim was to see if this new kind of study design would increase our knowledge in circumstances and causes leading to death in restraint situations. Data was collected retrospectively from all forensic autopsies performed in the Southern Finland area during 2010-2015. We went through 21,036 forensic autopsy cases and found 12 cases (0.06 %) in which a physical restraint was employed before death. Police officers were involved in the physical restraint in 7/12 of the cases: in two of these cases, police alone; in three cases, police and guards; and in two cases, police and health care personnel. Civilians carried out the restraint in 5/12 cases. With civilians responsible for the restraint, the cause of death was more likely considered to be a result of the restraint itself than in cases where police and other authorities were responsible for the restraint. This could be because civilians aren't educated about safe restraint methods, and they might themselves be intoxicated. Alcohol was the most common psychoactive substance found in this study and could be a risk factor for not only aggressive behavior but also death, since alcohol use can provoke cardiac arrhythmias and even sudden death. Based on this study, and previously published studies, we see restraint deaths as a varying spectrum of deaths, in which the death is often possibly a result of many factors, including the effects of agitation and restraint, intoxication, and cardiac and other illnesses.
RESUMO
BACKGROUND: Our case report provides the first clinical evaluation of autopsy practices for a patient death that occurs on the cloud. We question how autopsy practices may require adaptation for a death that presents via the 'Internet of Things', examining how existing guidelines capture data related to death which is no longer confined to the patient's body. CASE PRESENTATION: The patient was a British man in his 50s, who came to the attention of the medical team via an alert on the cloud-based platform that monitored his implanted cardioverter defibrillator (ICD). The patient had a background of congenital heart disease, with previous ventricular fibrillation cardiac arrest, for which the ICD had been implanted two years earlier. Retrospective analysis of the cloud data demonstrated a gradually decreasing nocturnal heart rate over the previous three months, falling to a final transmission of 24 beats per minute (bpm). In the patient post-mortem the ICD was treated as medical waste, structural tissue changes precluded the effective evaluation of device hardware, potential issues related to device software were not investigated and the cause of death was assigned to underlying heart failure. The documentation from the attending law enforcement officials did not consider possible digital causes of harm and relevant technology was not collected from the scene of death. CONCLUSION: Through this patient case we explore novel challenges associated with digital deaths including; (1) device hardware issues (difficult extraction processes, impact of pathological tissue changes), (2) software and data limitations (impact of negative body temperatures and mortuary radio-imaging on devices, lack of retrospective cloud data analysis), (3) guideline limitations (missing digital components in autopsy instruction and death certification), and (4) changes to clinical management (emotional impact of communicating deaths occurring over the internet to members of family). We consider the implications of our findings for public health services, the security and intelligence community, and patients and their families. In sharing this report we seek to raise awareness of digital medical cases, to draw attention to how the nature of dying is changing through technology, and to motivate the development of digitally appropriate clinical practice.

Background: Fetal death has various causes, among the most common are problems relating to the placenta, such as placental abruption or placental malformations such as placenta accreta. From the literature, it emerges that placental analysis at autopsy can allow for greater resolution of cases compared to clinical history and external examination of the fetus alone. Case Report: We report the case of a woman at the eleventh week of pregnancy who died in hospital. The medical history revealed two further previous pregnancies, both with births by cesarean section. The autopsy identified the cause of maternal death as acute cardiorespiratory arrest secondary to hemorrhagic shock from spontaneous uterine rupture. Hemorrhagic infiltrate was found in the intervillous placental spaces with rupture of the uterus due to placenta previa and accreta. Discussion: Placenta accreta is a condition in which a pathological adherence and/or invasion of the myometrium by the placenta is observed. This condition poses a problem during recovery with potential for severe bleeding. Therefore, we emphasize the macroscopic and histological analysis of the placenta, uterus and the ovaries in all cases of maternal-fetal death, suggesting however that the organs be analyzed both by gross analysis and after permanence in formaldehyde. Furthermore, in these cases, it is important to evaluate the clinical history and data, especially ultrasound scans performed in life, or insertion anomalies during instrumental investigations. For this reason, we recommend to collaborate with a multidisciplinary team in these cases, including the gynecologist and the forensic pathologist.

Background: Homicide by drowning in adults is rare. Usually, marks of violence are found on both the victim and the perpetrator, unless the victim was under the influence of alcohol, drugs, or was unexpectedly forced or dragged into the water. Indeed, many cases of drowning in adults are believed to be accidental, but they may be the result of drunken fights or attempts to make the death appear ac-cidental. In order to define the manner of death, cooperation between the forensic pathologist and the investigators is mandatory. Indeed, the autopsy is important to distinguish homicide by drowning from other kinds of drowning. The purpose of this study is to highlight the features of homicide by drowning. Materials and Methods: Literature search was conducted using PubMed databases, using the following keywords: "(homicide) and (drowning)". 3 articles were included in the systematic review, in addition to 3 cases observed in our institute. Conclusions: Both external examination and autopsy findings and the results of the investigation are essential to differentiate a homicide by drowning from accidental ones. The low specificity and variability of external and internal findings, the possibility of atypical asphyctic and nonasphyctic pathophysiological mechanisms, whose nature is not detectable at postmortem examinations, makes the diagnosis of cause of death difficult and often based on exclusion criteria only. In complex cases only using a strict forensic method allows to use the essential tools to identify the real manner of death.

Background: Healthcare-associated infections (HAIs) represent the most frequent adverse event in healthcare systems around the world. From a forensic point of view, HAIs show various legal implications. Therefore, it is essential in cases of death or injury from a suspected nosocomial infection that the infection itself, the source and the method of contamination are correctly diagnosed in order to evaluate any profiles of professional liability. Methods: This study combined a minireview of the scientific literature using the Pubmed search engine, the website of the Higher Institute of Health and the member states information sessions on infection prevention and control (IPC). Discussion: Despite the significant impact that HAIs have on healthcare systems, their severity is often not fully understood by healthcare professionals, leading to insufficient responses. In the autopsy setting, the diagnosis of these infections is not always simple due to the risk of post-mortem contamination determined by the endogenous bacterial flora. In the forensic field, the medical examiner during the autopsy can use various diagnostic techniques and investigative tools to identify the infection. Some usefulpp approaches include: 1) Macroscopic examination of the organs; 2) Histopathological investiga-tions; 3) Microbiological analyzes with the performance of swabs; 4) Immunofluorescence tests for the detection of antigens or antibodies on biological liquids; 5) Molecular tests. The choice of methods will depend on the nature of the suspected infection and the availability of diagnostic resources.

Background: Polycystic kidney disease is a cystic genetic disease. There are two forms: an autosomal dominant one, more common and typical of adults, and an autosomal recessive one, rarer and present in childhood. The autosomal dominant form is caused by genetic mutations of the PKD1 gene in 85% of cases and of PKD2 in 10-15% of cases. Case Report: We reported a case of 56-year-old woman with ADPKD, who had a kidney transplant and who was hospitalized for respiratory failure from Covid 19 disease. She was intubated, sedated and dialyzed, treated with antibiotics, immunosuppressants, diuretics and heparin. CT scan of the abdomen showed multiple cysts of various sizes in the liver and multiple cysts in the kidneys. The patient died after 20 days because she was unresponsive to therapy. The autopsy showed milky ascitic fluid in the abdomen, massive gastric haemor-rhage, intestinal fungal plaques, hepatic and renal polycystosis. The kidneys measured a total of 27 cm with a total weight of about 9 kg. The liver parenchyma appeared cavernous with multiple cysts. The kidney cysts contained bloody liquid. Conclusions: The case demonstrates how important it is in these subjects to evaluate not only the kidneys but also the liver which could present polycystosis and cause liver failure, affecting the severity of the pathology and death. This data is important to emphasize in the clinical management of these patients a close monitoring of liver function also from a preventative perspective in life.

Background: In the evolving field of forensic medicine, artificial intelligence (AI) technologies may revolutionize traditional autopsy practices by enhancing the precision and efficiency of postmortem examinations. Methods: A review of the literature was carried out on the Pub-med and Scopus search engines by inserting the keywords "artificial intelligence" AND "forensic" AND ("autopsy" OR "crime scene management" OR "forensic odontology" OR "post mortem interval" OR "forensic anthropology" OR "forensic sciences"). The works that analyzed the applications of artificial intelligence in the forensic and autopsy field were analyzed. Conclusion: The results showed the application of different forms of artificial intelligence such as machine learning, deep learning, robotics, artificial neural networks. Various applications are therefore possible in the autopsy field including forensic identification, analysis of radiological data through Virtopsy, estimation of the weapon used through analysis of firearm damage with ballistics, estimation of the Post-Mortem Interval (PMI), forensic toxicology. AI's potential to aid in the precise identification of causes of death, estimation of postmortem intervals. With forensic pathologists facing the constant challenge of making accurate diagnoses under pressure, AI applications can offer much-needed support by reducing subjective judgment and the inherent human error due to fatigue. Therefore, the integration of AI into autopsies, while promising in terms of efficiency and accuracy, demands a careful balance between technological advancement and ethical responsibility to ensure trust and integrity in forensic practices.

Postmortem computed tomography angiography (PMCTA) is a valuable tool for diagnosing vascular conditions, such as hemorrhages, in trauma cases. This case report demonstrates the use of the Voronoi algorithm to assess myocardial ischemia using coronary PMCTA. A male in his 70s was found unconscious in a car after colliding with a traffic light pole. Despite medical interventions, including pericardial drainage and cardiopulmonary resuscitation, the patient died two hours later. PMCTA revealed significant filling defects in the left anterior descending artery (LAD), consistent with plaque rupture and narrowing observed during autopsy. The cause of death in this case was likely cardiac tamponade due to cardiac rupture secondary to myocardial infarction resulting from LAD stenosis. Cardiac perfusion areas were analyzed using the Voronoi algorithm, demonstrating a total myocardial volume of 151.9 mL in the left ventricle. Perfusion volumes were calculated as 92.9 mL (61.2%) for the LAD, 34.2 mL (22.5%) for the left circumflex artery, and 24.9 mL (16.4%) for the right coronary artery. The predicted ischemic volume distal to the LAD stenosis was estimated to be 49.8 mL (32.8%). Furthermore, the ischemic areas observed during autopsy macroscopically corresponded well with the predicted ischemic regions. This case highlights that combining PMCTA with the Voronoi algorithm provides an accurate method for assessing myocardial ischemic areas, offering a non-invasive approach to visualize and quantify perfusion and ischemic regions.
RESUMO
Background and aims: Metabolic dysfunction-associated steatotic liver disease (MASLD) is a growing global epidemic in Türkiye and worldwide. The aim of this study was to evaluate the prevalence and predictors of MASLD and steatohepatitis among adults who died of unnatural causes including sudden death and non-burn trauma. Method: We conducted a prospective review of all consecutive adult forensic autopsies for natural (sudden unexpected) and non-natural (Suicidal, homicidal and accidental) suspicious deaths carried out at the Istanbul Council of Forensic Medicine from February to May 2022. Four wedge biopsies were extracted from sagittal sectioned liver specimens. A liver pathologist with 20 years of experience examined each case for steatosis, ballooning, inflammation, and fibrosis. Results: Among 1797 autopsies, 62 met inclusion criteria. Overall, 43.3 % (n = 26) of autopsies showed evidence of steatotic liver disease, with a distribution of steatosis severity as: Grade I (28.3 %), Grade II (6.6 %), and Grade III (8.3 %). All these cases met at least one cardiometabolic criteria and diagnosed with MASLD. Ballooning was observed in 20.0 % of cases (5 cases grades 1 and 7 cases grade 2), and Inflammation was present in 51.7 % (9 cases with grade 0-1, 12 with 1-2, 7 with 2-3, and 3 with 5-6). Notably, 46.1 % (n = 12) of MASLD cases and 20.0 % (n = 12) of all cases were diagnosed with steatohepatitis, with three cases exhibiting delicate perisinusoidal fibrosis and one case showing portal fibrosis. Conclusion: The histopathological findings from this autopsy study confirmed the markedly high prevalence of MASLD and steatohepatitis within the general adult population, highlighting the concerning burden of steatotic liver disease in Türkiye.
RESUMO
Avalanche fatalities are quite rare in the Czech Republic. Due to the presence of avalanche fields in the two Czech mountains, forensic pathologists at some forensic medicine departments may encounter this specific mechanism of accidental death. The authors summarize medicolegal aspects of deaths in avalanches in the territory of the Czech Republic for the twenty-three-year period between 1993-2015. Ten avalanche fatalities were recorded during study period. The studied group consisted of nine male and one female victims. The average age of the deceased was 27.9 years. Skiers or ski-alpinists died in the avalanche in five cases (50%), climbers in two cases (20%), snowboarders in one case (10%), cross-country skiers in one case (10%) and in one case it was a fatality of child playing on a snowy hill (10%). The cause of death was suffocation in four cases (40%), blunt trauma in four cases (40%), and in the remaining two cases it was the survival of trapped persons several hours after being rescued from the avalanche in the hospital; both victims subsequently died as a result of prolonged shock (20%) due to a combination of prolonged suffocation and hypothermia. The time interval from the fall of the avalanche to the rescue of the trapped person was in the range of minutes to 3 hours. The presence of alcohol or drugs was not detected in any studied case.

Death from positional asphyxia occurs when the victim is found in a position that interferes with adequate breathing. We present an unusual case of a 67-yearold man who was found deceased trapped in a badger sett. The autopsy revealed marked congestion, cyanosis and a multitude of pinpoint hemorrhages in the face, neck and upper chest. Confluent scleral and conjunctival hemorrhage were observed and numerous petechial bleedings were found in the oral mucosa and within the reflected scalp. Death was attributed to positional asphyxia due to head-down position in a badger sett.

BACKGROUND: Alzheimer disease (AD) is a heterogenous and multifactorial disease, and its pathology is partly driven by microglia and their activated phenotype. Brain organoids (BOs) are gaining prominence as a relevant model of the human brain for the study of AD; however, BOs are commonly devoid of microglia. To overcome this limitation, current protocols incorporate microglia through either (1) co-culture (BO co-culture), or (2) molecular manipulation at critical windows of BO development to have microglia arise innately (BO innate cultures). It is currently unclear whether the microglia incorporated into BOs by either of these two protocols differ in function. METHODS: At in vitro day 90, BO innate cultures and BO-co-cultures were challenged with the AD-related ß-amyloid peptide (Aß) for up to 72 h. After Aß challenge, BOs were collected for immunoblotting. Immunoblots compared immunodensity and protein banding of Aß and ionized calcium-binding adapter molecule 1 (IBA1, a marker of microglial activation) in BOs. The translational potential of these observations was supported using 56 human cortical samples from neurocognitively normal donors and patients with early-onset AD and late-onset AD. Statistical analyses were conducted using the Kruskal-Wallis test, a two-way ANOVA, or a simple linear regression, and where applicable, followed by Dunn's or Sidak's test. RESULTS: We show that BO co-cultures promote Aß oligomerization as early as 24 h and this coincides with a significant increase in IBA1 levels. In contrast, the Aßs do not oligomerize in BO innate cultures and the IBA1 response was modest and only emerged after 48 h. In human cortical samples, we found IBA1 levels correlated with age at onset, age at death, and the putative diagnostic Aß(1-42)/Aß(1-40) ratio (particularly in their oligomeric forms) in a sex-dependent manner. CONCLUSIONS: Our unique observations suggest that BOs with innate microglia model the response of a healthy brain to Aß, and by extension the initial stages of Aß challenge. It would be impossible to model these early stages of pathogenesis in BOs where microglia are already compromised, such as those with microglia incorporated by co-culture.

The beginning of post-mortem evaluation studies through minimally invasive procedures began between 1800 and 1930. It started with Dr. Howard Kelly and was later followed by Décio Parreiras and Werneck Genofre, due to the yellow fever outbreak in Brazil. However, despite its early beginnings, the intensification of the research on this field occurred around 2010, when the publications about this subject became three times more frequent than before. There are basically two classifications for this procedure. The first one is virtual non-invasive autopsy, which is based only on imaging exams; the second is the minimally invasive autopsy, in which imaging exams are associated with other techniques such as biopsy and angiography. The main objective of the present study is to evaluate the existent data published about virtual autopsy from 2010, and highlight the key concepts related to this theme. A search was conducted in PUBMED, MEDLINE, and LILACS databases using the descriptors "virtual autopsy" and "minimally invasive autopsy", the review protocol has been registered on Open Science Framework (OSF), the total number of studies included were 28, and the data was presented through the PRISMA-ScR flowchart. Although, it is well known that this theme is recent in research fields and, because of that, there is still a lot to explore.

Kidney cysts in humans are mainly caused by inheritable polycystic kidney disease. Although they are a regular finding in laboratory mice, their occurrence upon dissection has not been systematically investigated, yet. Therefore, the aim of this report was to investigate on prevalence, phenotype and aetiology of spontaneously occurring kidney cysts in mice by retrospectively analysing the laboratory-receipt tables of the in-house laboratory of a central animal facility in North Rhine-Westphalia, Germany, years 2009-2019. A percentage of 0.4% of dissected mice displayed kidney cysts, with more male than female animals affected and average age equal to that of all dissected animals. Preliminary report in half of the cases was distended abdomen, and a few individuals displayed additional pathologic alterations of kidneys, most commonly dilated renal pelvis, or extrarenal comorbidities. Kidney cysts occurred independently of a renal phenotype of the transgenic strain or presence of infectious agents in health monitoring. To conclude, kidney cysts were characterized as harmless for affected mice but, as inheritability is suggested according with the literature, affected animals should be excluded from breeding.
RESUMO
Cardiac tamponade from ruptured intrathoracic organs can lead to sudden cardiac death. In rare circumstances, the pulmonary artery can be the source of hemopericardium. We describe a case of a 62-year-old woman with no significant past medical history, who presented with sudden unexpected death. A forensic autopsy revealed 500 ml of hemopericardium. Further dissection demonstrated a saccular aneurysm in the pulmonary artery trunk, along with the evidence of prior dissection, i.e., neointimal layer. Persistent ductus arteriosus (PDA) was also present. Pulmonary artery aneurysms (PAA) are rare and often associated with congenital heart disease (CHD). PDA is the most common CHD related to PAA. Secondary pulmonary hypertension makes the pulmonary artery vulnerable to medial degeneration and increases the risk of dissection and rupture. Careful inspection of the great vessels and congenital anomalies are essential in the forensic autopsies for sudden death investigation.
RESUMO
The two most prevalent childhood vascular abnormalities are infantile hemangioma (IH) and port-wine stain (PWS). They become apparent shortly after birth but have distinct pathophysiology and clinical manifestations. The goal of this study was to determine if mother's history of angioma or PWS is associated with these vascular abnormalities. We evaluated an UK anonymized electronic medical records database with medical records that were linked between children and their mothers. Cox proportional hazards models were used to evaluate the association between maternal factors and the time of onset of either IH or PWS in children. Between 2004 and 2021, 639,085 children were linked to their mom's medical data with a total of 4,270,773 person-years of follow up. Children born to mothers with an angioma as compared to a mother without an angioma were more than 60% more likely to have an IH (HR: 1.64 [1.07, 2.52]). Children born to mothers with a PWS as compared to children born to mothers without a PWS were nearly 20 times more likely to have a PWS (18.95 [4.71,76.26]). Mothers with angiomas were not more likely to have children with PWS and mothers with PWS were not more likely to have children with IH. The effect estimates were minimally changed after adjustment. We demonstrated that children born to mothers with angiomas or PWS were at increased risk of IH or PWS, respectively.

INTRODUCTION: Facial gunshot wounds have devastating functional and aesthetic consequences for the patient. If associated with penetrating craniocerebral injuries, the prognosis is rather compromised even with appropriate medical and surgical treatment. Chop-off injuries with penetrating wounds constitute a challenging situation for the facial reconstructive surgeon in facial trauma. OBSERVATION: This case involved a 49-year-old man who sustained an accidental facial shot from a pellet gun. Radiological and clinical investigations revealed complex ballistic trauma to the maxillofacial region, with projectiles reaching the base of the skull. One of the projectiles migrated via the carotid canal towards a cerebral artery, leading to obstruction of the artery with cerebral infarction. An autopsy was performed which evaluated that the shooting distance was compatible with a long distance, causing the dispersion of lead grains with the absence of a wad inside the trauma site. CONCLUSION: In some cases of facial gunshot wounds, despite a complex and extensive lesion assessment, death may occur due to a neurological complication rather than sustaining hemodynamic shock, depending on the trajectory of the projectiles.

INTRODUCTION: Human rabies (HR) is a lethal zoonotic disease caused by lyssaviruses with increase in the number of cases post-coronavirus disease 2019 (COVID-19) pandemic. METHODOLOGY: We report a case of human rabies in a patient from a rural area of Ceará, northeastern Brazil in 2023, who was bitten by a white-tufted-ear marmoset (Callithrix jacchus jacchus). The patient was co-infected with severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) and was diagnosed by minimally invasive autopsy (MIA). RESULTS: MIA offers many advantages related to biosafety, and speed of sample acquisition; and markedly reduces disfigurement of the body compared with complete autopsy. It is a great alternative in COVID-19 patients. CONCLUSIONS: New methods such as MIA are a promising tool for diagnosis, and have the potential to improve family cooperation and support rabies surveillance.

In forensic medicine, hypothermia is a frequently encountered cause of death, and this characteristic provides public health information to prevent similar deaths in the future. Previous studies revealed regional differences in hypothermia occurrence (indoors or outdoors). However, to our knowledge, no recent studies in Japan have directly compared the characteristics of indoor- and outdoor-onset cases based on forensic autopsy reports. Hence, this study aimed to determine the characteristics and risks of unexpected hypothermia-related death. It included 218 cases from the Chiba Prefecture, Japan, wherein forensic autopsies were performed and hypothermia was diagnosed; these cases were categorized into indoor- and outdoor-onset cases, and their characteristics were examined. The results showed no significant differences between the two groups in relation to the age of onset or residential environment (i.e., the presence or absence of cohabitants). The outdoor-onset group tended to have a higher incidence of dementia. Regarding the causes of hypothermia, the indoor group had more internal causes (p < 0.0001), whereas the outdoor group had more primary and external causes (p < 0.0001 and p = 0.0029, respectively). The indoor group was more undressed than the outdoor group. Atypical antipsychotic components were predominantly detected in the blood in the outdoor group (p = 0.0077). The body mass index tended to be lower in the indoor group than in the outdoor group. Broadening public awareness of the present study findings may aid in developing preventative strategies for hypothermia based on the location of onset.
