ABSTRACT
When a charred corpse is found, a primary unavoidable phase of the subject's identification is performed. Then, the medico-legal investigation must clarify whether the charring occurred before or after death, and so establish a differential diagnosis between accidental, homicidal, or suicidal modality. We report three cases of charred corpses in which a death dynamic was initially suspected but subsequently disproved: a suicidal intoxication in arson at first thought to be homicidal strangulation, a suicidal hanging revealed by neck haemorrhages in a suspected accidental fire, a femicide through ligature strangulation concealed with the simulation of a car accident. Many of the events are accidental, related to fires or traffic accidents. However, it must be considered that charring following a murder was deliberately provoked to prevent the identification of the subject and to conceal evidence of how the murder occurred. Because of the complex operational conditions in the study of a charred corpse, all the diagnostic tools proper to forensic science should be held beyond the preliminary circumstantial suggestions. We aim to emphasise the importance of a multidisciplinary approach since the solution of the three cases was possible thanks to the combination of crime scene investigation, radiological exams, autopsy, and histopathological and genetic analysis.

Every finding during a neck autopsy may be essential for accurately diagnosing and explaining the mechanism of death. In this prospective study in the Department of Forensic Medicine and Toxicology of Jordan University Hospital, 17 out of 95 neck autopsies revealed contusions of the laryngeal mucosa in the vocal or perivocal area. These contusions were found to be associated with various causes of death, including mechanical asphyxia (such as throttling, ligature strangulation, hanging, smothering, choking, plastic bag asphyxia, gagging, and inhalation of blood) and other causes (such as atypical drowning, carbon monoxide poisoning, head injury due to a road traffic accident, burns, electrocution, and brain edema). This study provides insight into the mechanisms of this important lesion and may contribute to a better understanding of the cause of death.

A risk of suicide in the course of a psychiatric disorder will often be answered with an admission for inpatient psychiatric treatment, resulting in a high potential of suicidal behavior on the ward. Despite extensive safety precautions and therapeutic interventions, suicides still occur within psychiatric hospitals. Such incidents, known as inpatient suicides, are rare but significant, necessitating further examination. We present the case of a 91-year-old suicidal male patient, who committed suicide on an open ward on a Sunday morning by blocking his nostrils with cotton and tissue and breathing into a pillow, leading to death by asphyxia. The case report aims to draw attention to the possibility of this extraordinary method of suicide, demonstrating that a suicide can be accomplished in a psychiatric hospital even without the use of prohibited dangerous objects.

AIM: The aim of this study was to determine how front-line health professionals identify and manage nonfatal strangulation events. DESIGN: Integrative review with narrative synthesis was conducted. DATA SOURCES: A comprehensive database search was conducted in six electronic databases (CINAHL, Wed of Science, DISCOVER, SCOPUS, PubMed and Scholar) resulting in 49 potentially eligible full texts, reduced to 10 articles for inclusion after exclusion criteria were applied. REVIEW METHODS: An integrative review was undertaken in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) Statement guidelines. Data were extracted, and a narrative synthesis using Whittemore and Knafl (2005) framework was undertaken to determine how front-line health professionals identify and manage nonfatal strangulation events. RESULTS: The findings identified three main themes: an overall failure by health professionals to recognize nonfatal strangulation, a failure to report the event and a failure to follow up on victims after the event. Stigma and predetermined beliefs around nonfatal strangulation, along with a lack of knowledge about signs and symptoms, were the salient features in the literature. CONCLUSION: Lack of training and fear of not knowing what to do next are barriers to providing care to victims of strangulation. Failure to detect, manage and support victims will continue the cycle of harm through the long-term health effects of strangulation. Early detection and management of strangulation are essential to prevent health complications, particularly when the victims are exposed to such behaviours repeatedly. IMPACT: This review appears to be the first to explore how health professionals identify and manage nonfatal strangulation. It identified the significant need for education and robust and consistent screening and discharge policies to assist health providers of services where victims of nonfatal strangulation attend. NO PATIENT OR PUBLIC CONTRIBUTION: This review contains no patient or public contribution since it was examining health professionals' knowledge of identifying nonfatal strangulation and the screening and assessment tools used in clinical practice.

The reliance on external injuries for justice is misguided given that assault injuries may be less visible among victims of color due to increased melanin in the skin. To date, however, less is known whether racial/ethnic disparities extend to officers' identification of signs of nonfatal strangulation (NFS). The current study estimates the extent of NFS indicators identified by officers who completed a standardized strangulation assessment in 133 family violence complaints. Breathing difficulties were the most common symptoms identified by officers (98%), followed by external signs (89%), and symptoms of impeded blood circulation (87%). Compared to cases involving White/Asian survivors, officers were less likely to identify external injuries on Black survivors' neck, chin, and chest/shoulders. While racial/ethnic differences did not emerge for symptoms of disrupted airflow, Hispanic survivors were twice as likely to report losing control of bodily functions. Implications for policy and practice are discussed.

In recent years, the increase in the number of cases of postural asphyxia has gradually attracted the attention and discussion of forensic scientists domestically and internationally, but a systematic, comprehensive and recognized expert consensus and identification standard has not been established at home and abroad. This paper reviews the case characteristics, occurrence, mechanism of death, and identification criteria of postural asphyxia, to provide reference for future research.

OBJECTIVE: Our goal was to investigate the frequency of specific signs and symptoms following sexual assault-related non-fatal strangulation (NFS) and to explore the interaction between assault characteristics and physical exam findings. METHODS: This retrospective observational study included all adults (>18 years) reporting strangulation during sexual assault who presented for a forensic sexual assault exam at one of six urban community hospitals contracted with a single forensic nurse agency. Demographic information, narrative elements, and physical exam findings were abstracted from standardized sexual assault reporting forms. We analyzed data with descriptive statistics and compared specific variables using chi-square testing. RESULTS: Of the 580 subjects 99% were female, with a median age of 27 (interquartile range 22-35 years). The most common injury location was the neck (57.2%), followed by the mouth (29.1%). We found that 19.1% of the victims had no injuries evident on physical exam and 29.8% reported a loss of consciousness. Eye/eyelid and neck findings did not significantly differ between subjects who reported blows to the head in addition to strangulation and those who did not. The time that elapsed between assault and exam did not significantly correlate with the presence of most head and torso physical exam findings, except for nose injury (P = 0.02). CONCLUSION: Slightly more than half of the victims who reported strangulation during sexual assault had visible neck injuries. Other non-anogenital findings were present even less frequently, with a substantial portion of victims having no injuries documented on physical exam. The perpetrators' use of blows to the head may account for many of the non-anogenital injuries observed, but not for the neck and eye/eyelid injuries, which may be more specific to non-fatal strangulation. More research is needed to definitively establish strangulation as the causal mechanism for these findings, and to determine whether any long-term neurologic or vascular sequelae resulted from the observed injuries.

Emerging evidence suggests that an onset or escalation of interpersonal violence has been occurring during the COVID-19 pandemic, particularly among persons in intimate or familial relationships. Strangulation (or neck compression) is a common form of interpersonal violence and can result in serious adverse health outcomes, including death. The identification and attribution of injuries from non-fatal strangulation are complex, as there may be an absence of external signs of injury and their appearance may be delayed by many days. There is a heavy reliance on clinician identification of 'red flag' symptoms and signs, the presence of which necessitates urgent further assessment. Additional challenges arise when acute non-fatal strangulation symptoms and signs are shared with other clinical conditions. In such cases, differentiating between the conditions based on the symptoms and signs alone is problematic. We present the diagnostic challenges faced when conducting forensic assessments of COVID-19-positive and suspected COVID-19 (S/COVID) patients following allegations of non-fatal strangulation in the setting of physical and sexual assaults. The implications of shared symptoms and signs, for forensic clinicians, primary healthcare, and emergency practitioners, as well as other frontline service providers, are discussed.

OBJECTIVE: To describe characteristics of strangulation, and associated medical care, documentation, and injuries of women after nonfatal intimate partner strangulation (NF-IPS) who present for care to a community-based emergency department (ED) with an associated intimate partner violence (IPV) advocacy program between 2008 and 2016. SETTING, DESIGN, AND PARTICIPANTS: A retrospective review of 345 female ED patients' medical records who sought care at a community hospital ED following a physical assault including strangulation by an intimate partner was conducted. Demographics, characteristics related to reported signs and symptoms, injuries, and subsequent imaging, diagnoses, and discharge information were abstracted. RESULTS: Commonly reported symptoms were neck pain (67.2%) and headache (45.8%), with fewer patients reporting more severe symptoms such as loss of consciousness (22.6%), dysphagia (25.0%), or dysphonia (26.7%). Rates of patients disclosing strangulation to the entire multidisciplinary team and dedicated neck imaging appeared to improve between 2008 and 2014. Among the 45 patients with noted head and neck findings, 2 patients were found to have an internal carotid artery dissection, 2 patients were found to have strokes, and 1 patient was found to have an intracranial hemorrhage. CONCLUSIONS: Survivors of NF-IPS may present to community-based hospitals, and existing imaging guidelines can support clinicians in identifying serious internal injury such as carotid artery dissection and stroke. Further research is needed to better discern symptoms previously attributed to psychological trauma from poststrangulation brain injury. This study contributes to the growing literature on NF-IPS with data specific to community-based ED visits.

OBJECTIVE: Non-fatal strangulation assessment is challenging for clinicians as clear guidelines for evaluation are limited. The prevalence of non-fatal strangulation events, clinical findings, frequency of injury on computed tomography angiogram (CTA) and outcomes across two trauma centres will be used to improve this assessment process. METHODS: This is a retrospective observational study of adult presentations during 2-year period to two major-trauma referral hospitals and subsequent 12 months to identify delayed vascular injury. Patients included using standardised search terms. Demographic data, clinical findings, radiological reports and outcomes were included for review. RESULTS: A total of 425 patients were included for analysis. Self-inflicted injury comprised 62.1%, with domestic violence (28.5%) and assault (9.4%) the remainder. Manual strangulation events 36.7% of overall presentations and 63.3% following ligature strangulation (ligature strangulation, incomplete and complete hanging). On examination soft signs present in 133 (31.2%) cases, commonly neck tenderness in isolation. No hard signs suggesting vascular damage. Vascular injury was demonstrated in three cases (0.7% of the total cohort and 1.5% of CTA scans completed), and all occurred in ligature strangulation events as a result of hanging. No patients had delayed vascular injury in the 12-month period post-initial presentation. CONCLUSIONS: In non-fatal strangulation presentations, the majority have subtle signs of neck injury on examination with inconsistent documentation of findings. Low rate of vascular injury overall (0.7%), and entirely in hanging events. No longer-term vascular sequalae identified. Improving documentation focusing on hypoxic insult and evidence of airway trauma is warranted, rather than a reliance on computed tomography imaging to delineate a traumatic event in non-fatal strangulation.

BACKGROUND: Non-fatal strangulation is a dangerous mechanism of injury among survivors of intimate partner violence and sexual assault, with inadequate evidence to guide investigation in the emergency department (ED). The primary objective is to identify the proportion of intimate partner violence and sexual assault where non-fatal strangulation occurs, and to describe the sequelae of injuries. METHODS: Health records review of patients treated at the Sexual Assault and Partner Abuse Care Program (SAPACP) and/or Trauma Program at a tertiary level hospital between January 2015 and December 2018. Eligible patients were greater than 16 years old, seen by the SAPACP or trauma team for intimate partner violence and sexual assault, and had a non-fatal strangulation injury. Data were abstracted from the standardized assessment completed by the SAPACP nurse. Descriptive statistics were used. RESULTS: We identified 209 eligible cases of non-fatal strangulation, among 1791 patient presentations to the SAPACP. Median patient age was 27 years, and 97.6% were female. Computed tomography (CT) of the head was obtained in 22.5%, and CT angiography (CTA) of the head and neck in 6.2% of cases. Eleven significant injuries were identified. Two cases of vascular abnormalities: internal carotid artery indentation with possible intramural hematoma and possible internal carotid artery dissection. Other injuries included delayed bilateral subdural hematomas, a depressed skull fracture, and six nasal fractures. CONCLUSION: We found over 10% prevalence of non-fatal strangulation in survivors of intimate partner violence and sexual assault. There was a low rate of clinically important injury on the index ED visit secondary to non-fatal strangulation. Severe injury was primarily secondary to concomitant trauma, and utilization of CTA in this cohort was low. Increased awareness is needed among ED physicians regarding the need to consider CTA head and neck.
RéSUMé: CONTEXTE: La strangulation non mortelle est un mécanisme dangereux de blessures chez les survivants de violence conjugale et d'agression sexuelle, avec des preuves insuffisantes pour guider l'enquête aux services d'urgence (SU). L'objectif principal est d'identifier la proportion de violence conjugale et d'agression sexuelle où survient un étranglement non mortel, et de décrire les séquelles des blessures. MéTHODES: Examen des dossiers médicaux des patients traités au programme de soins pour les agressions sexuelles et les abus de partenaires (SAPACP) et/ou au programme de traumatologie d'un hôpital de niveau tertiaire entre janvier 2015 et décembre 2018. Les patients éligibles avaient plus de 16 ans, étaient vus par le SAPACP ou l'équipe de traumatologie pour des violences entre partenaires intimes et des agressions sexuelles, et présentaient une blessure non mortelle par strangulation. Les données ont été extraites de l'évaluation standardisée réalisée par l'infirmière du SAPACP. Des statistiques descriptives ont été utilisées. RéSULTATS: Nous avons identifié 209 cas éligibles de strangulation non fatale, parmi les 1791 présentations de patients au SAPACP. L'âge médian des patients était de 27 ans, et 97,6 % étaient des femmes. La tomodensitométrie (TDM) de la tête était réalisée dans 22,5 % des cas, et l'angiographie TDM de la tête et du cou dans 6,2 % des cas. Onze blessures significatives ont été identifiées. Deux cas d'anomalies vasculaires : indentation de l'artère carotide interne avec possible hématome intramural et possible dissection de l'artère carotide interne. Les autres blessures comprenaient des hématomes sous-duraux bilatéraux retardés, une fracture du crâne déprimée et six fractures nasales. CONCLUSION: Nous avons constaté une prévalence de plus de 10 % de strangulation non mortelle chez les survivants de violence conjugale et d'agression sexuelle. Il y avait un faible taux de blessures cliniquement importantes lors de la visite aux urgences de référence, secondaires à une strangulation non fatale. Les lésions graves étaient principalement secondaires à des traumatismes concomitants, et le recours à l'angiographie dans cette cohorte était faible. Il est nécessaire de sensibiliser davantage les médecins des urgences à la nécessité d'envisager une angioplastie de la tête et du cou.

The authors present the first case, to the best of our knowledge, of a preplanned suicide by self-waterboarding. Waterboarding (WB) is a military method of torture in which water is poured into the nostrils and the mouth of a victim, to evoke the sensation of asphyxiation by drowning. The victim was a 22-year-old male student, who was found dead and naked in the bathtub. His head was covered by a soaked canvas bag, and his hands were tied with two nylon ropes and a padlock. The water jet of the showerhead was specifically directed at the victim's head, so that the canvas bag could be soaked with water. The cause of death was defined as the combination of asphyxiation by drowning with the direct suffocation provoked by the soaked canvas bag in the context of the waterboarding practice. Finally, the authors discuss the differential diagnosis regarding the modality (suicide versus homicide) through which this case of waterboarding was performed. The case is intended to be used as source data for similar forensic cases, where a multidisciplinary approach is advisable in such complex cases.

Determination of mechanical asphyxia as the cause of death has always been difficult for forensic pathologists, particularly when signs of asphyxia are not obvious on the body. Currently, depending on only physical examination of corpses, pathologists must be cautious when making cause-of-death appraisals. In a previous study, four biomarkers-dual-specificity phosphatase 1 (DUSP1), potassium voltage-gated channel subfamily J member 2 (KCNJ2), miR-122, and miR-3185-were screened in human cardiac tissue from cadavers that died from mechanical asphyxia compared with those that died from craniocerebral injury, hemorrhagic shock, or other causes. Expression of the markers correlated with death from mechanical asphyxia regardless of age, environmental temperature, and postmortem interval. However, a single biological index is not an accurate basis for the identification of the cause of death. In this study, receiver operating characteristic curves of the ΔCq values of the four indexes were generated. The diagnostic accuracy of the indexes was judged according to their area under the curve (DUSP1: 0.773, KCNJ2: 0.775, miR-122: 0.667, and miR-3185: 0.801). Finally, a nomogram was generated, and single blind experiment was conducted to verify the cause of death of mechanical asphyxia.

The diagnosis of mechanical asphyxia remains one of the most difficult issues in forensic pathology. Asphyxia ultimately results in cardiac arrest (CA) and, as there are no specific markers, the differential diagnosis of primitive CA and CA secondary to asphyxiation relies on circumstantial details and on the pathologist experience, lacking objective evidence. Histological examination is currently considered the gold standard for CA post-mortem diagnosis. Here we present the comparative results of histopathology versus those previously obtained by 1H nuclear magnetic resonance (NMR) metabolomics in a swine model, originally designed for clinical purposes, exposed to two different CA causes, namely ventricular fibrillation and asphyxia. While heart and brain microscopical analysis could identify the damage induced by CA without providing any additional information on the CA cause, metabolomics allowed the identification of clearly different profiles between the two groups and showed major differences between asphyxiated animals with good and poor outcomes. Minute-by-minute plasma sampling allowed to associate these modifications to the pre-arrest asphyxial phase showing a clear correlation to the cellular effect of mechanical asphyxia reproduced in the experiment. The results suggest that metabolomics provides additional evidence beyond that obtained by histology and immunohistochemistry in the differential diagnosis of CA.

Death following accidental suffocation due to overlaying is often overlooked, and still attributed to Sudden Infant Death Syndrome (SIDS). We report a case of sudden infant death following accidental suffocation due to breast overlaying during breastfeeding. We report the death of a two-month-old male baby, without medical history, who was found lifeless wedged under his mother's breast. The mother subsequently admitted that she had fallen asleep while breastfeeding and awoke a few minutes later to find him wedged under her breast and not breathing. External examination of the infant's body revealed right frontal congestion with reddish-purple colour of the right frontal skin corresponding to where the mother's breast had overlaid his face with bilateral conjunctival petechiae with no signs of external injury. Internal examination revealed congestion with petechiae marks of the internal side of the right frontal scalp, with moderate congestion and few petechiae marks at the level of the lungs. The histopathological examination showed non-specific passive congestion, with no abnormalities. The cause of death was attributed to accidental suffocation following obstruction of external airways by the mother's breast during breastfeeding. Accidental asphyxia cases require extensive investigation of the circumstances surrounding death, reconstruction of events, and careful documentation of the findings observed at autopsy with full histological examination which may become relevant in a specific case in later stages of the investigation.

The determination of cause of death is one of the most important tasks in forensic practice. However, asphyxia is a difficult cause of death to determine, especially when the deceased has an underlying disease that can lead to a sudden unexpected death, such as coronary atherosclerotic heart disease (CAHD, which is the leading cause of sudden cardiac death, SCD), because its determination is currently still based on an exclusion strategy. In this study, gas chromatography coupled with high-resolution mass spectrometry (GC-HRMS)-based untargeted metabolomics was employed to obtain the pulmonary metabolic profiles of rats who died from asphyxia and SCD. First, fourteen metabolites were identified to investigate the mechanism of death from asphyxia, and we proposed some explanations that may account for these metabolic alterations, including the perturbation of amino acid metabolism, lipid metabolism, and energy metabolism (TCA cycle). Second, we discovered eight potential biomarkers to differentiate between asphyxia and SCD as the cause of death. The excellent classification performances of the eight individual biomarkers and their combination in fresh lung tissue were observed. Third, we also explored the relative change in the concentration of the eight metabolites and their classification performance in decomposed tissue (at 24 h postmortem). Lactic acid, pantothenic acid, and the combination of the eight biomarkers can be recognized as perfect classifiers to discriminate asphyxia from SCD even when decomposition has occurred. Our results showed that GC-HRMS-based untargeted metabolomics can be used as a promising tool to explore the metabolic alterations of the death process and to determine the cause of death.

Intimate partner violence (IPV) is a significant public health problem that has profound effects on the physical and psychological well-being of millions of Americans. It is known that strangulation is one of the most lethal forms of IPV. Frequently, a lack of visible external trauma is present, and attempted strangulation may be accompanied by other more severe injuries to the head and face; thus, the signs and symptoms of nonfatal strangulation may be overlooked. Because the emergency department (ED) is frequently the first point of contact for an individual who has experienced any type of IPV, it is imperative that providers have the knowledge and skill set for the identification and management of this patient population. The purpose of this article is to present a discussion of the challenges faced by ED providers in the clinical decision-making process when caring for a patient who has experienced nonfatal strangulation.

Perthes syndrome is defined by the association among subconjunctival hemorrhage, cervicofacial cyanosis and petechiae up to neurological manifestations. Violent compression of the thorax or thoracoabdominal block after forced inspiration with glottis closure due to effort is the mechanism responsible for the syndrome. Prognosis is generally good if the compression is brief and cardiopulmonary resuscitation has been started early. The purpose of this study was to describe the features of Perthes syndrome among children.
