BACKGROUND: Interpersonal violence impacts communities, victims, perpetrators, families, and children. This audit of 315 cases of non-sexual assault compares characteristics of general assault to those of non-fatal strangulation (NFS). METHOD: Clinical review of all cases referred to Clinical Forensics Australian Capital Territory (CFACT) by ACT Policing between 2018 and 2022, following allegations of non-sexual assault. Descriptions of the model of care, victim characteristics, alleged perpetrators, and presentations in NFS versus general assault, from forensic medical examination...

Childhood is a long period extending up to the age of 18 years. Childhood encompasses different developmental stages; each stage has specific characteristics. This 5-year study included 244 autopsied children who died unexpectedly due to natural causes. This study was conducted in the forensic pathology unit of the Egyptian Forensic Medicine Authority (EFMA). Pathological causes of death were diagnosed in 181 cases, representing nearly three-quarters (74.2 %) of cases. Males represented 60.8 % of these cases...

Coronary atherosclerosis is due to build-up of plaque within the coronary arteries. Post-mortem computed tomography (PMCT) allows non or minimally invasive visualization of abnormalities prior to an autopsy, however PMCT-angiography (PMCTA) greatly enhances relevant findings, especially in viewing the cardiovascular system which is important in the diagnosis of coronary atherosclerosis. Contrast media used in PMCTA however has been reported to cause distortion of tissue which may interfere with post-mortem investigation outcomes...

OBJECTIVE: This study aimed to analyze a sample (n = 65) of juvenile homicide/attempted homicide cases in terms of psychiatric, demographic, criminal characteristics, IQ scores, and Rorschach test (where available) characteristics and decisions on criminal responsibility. METHOD: Data were collected through a retrospective chart review of cases between the ages of 12 and 18 at the time of the offense, who were referred to the Observation Department of the Council of Forensic Medicine (Adli Tip Kurumu Baskanligi, Gözlem İhtisas Dairesi) for determination of criminal responsibility between 2014 and 2019 and who were assessed under inpatient status by law...

The number of unidentified corpses has been increasing in recent years. There is a need for an objective and readily applicable method to estimate age, which is important information for identification. In previous reports, we reported that the protein folding ratio (RPF ) of skin, as measured by Raman spectroscopy using cross sections of skin samples, is highly correlated with age. In this study, we investigated the possibility of estimating age by measuring Raman spectra from the skin surface of cadavers using a portable device...

BACKGROUND: Sexual violence is a crime that affects people of all genders. While focus is frequently on female survivors, it is crucial to acknowledge that males also experience sexual violence and to ensure that gender-sensitive services are available to all survivors. Understanding the prevalence of, and factors associated with, sexual violence against males is a critical first step in addressing this issue. We aim to address the lack of data in relation to sexual violence against males...

The marks left by the bite of a subject (bitemark) represent an unequivocal character, being useful in identifying the possible perpetrator of a crime. To date, the analysis of bitemarks is mainly based on the direct vision of photographic finds and on the visual comparison with the teeth of the hypothetically responsible person. However, the bitemark also retains three-dimensional characteristics detectable with a 3D scanner. In this pilot study, an innovative method of bitemark analysis, utilizing a three-dimensional scanner and some software, will be introduced, enabling a quantitative comparison of bitemarks and their corresponding human dentitions...

Most studies of violence from the health care system lack reliable information about the counterpart, which is important for distinguishing between different types of violence. Since 2014, the emergency department at Odense University Hospital in Denmark has routinely registered information about the counterpart. The purpose of this study was to evaluate the completeness of registering information about the counterpart during routine registration of victims of interpersonal violence in the emergency department...

Analysis and interpretation of the findings for γ-hydroxybutyrate (GHB) in related fatalities remains problematic. Indeed, GHB is a naturally occurring compound present in both the mammalian central nervous system and peripheral tissue. Moreover, a postmortem increase in endogenous GHB concentration has been observed, especially in blood. Facing this issue, the use of an alternative matrix such as vitreous humor (VH) can thus be particularly interesting for GHB testing and quantification. VH is considered to be less prone to postmortem redistribution, is easy to collect, and has relatively few interfering compounds for the analytical process...

The potential for recreational abuse of the analgesic and antiepileptic drug pregabalin is now well established in the literature. The potential minimum lethal dose in post mortem cases is however less defined. All post mortem examinations in Northern Ireland where the cause of death was found to be due to pregabalin were examined for demographic and toxicological analysis. Deaths are generally seen in young men, especially 30-39-year-olds, many of whom have a history of substance misuse and are often prescribed pregabalin...

Fractures of the laryngohyoid complex are classically associated with deaths due to strangulation. Recent studies, however, indicate the possible presence of such fractures in fatal falls. The primary focus of this systematic review is to analyze the characteristics of laryngohyoid fractures in the context of falls to aid in a more accurate interpretation of autopsy findings. Search for relevant literature occurred on PubMed on the 26th of October 2022, and Embase and Web of Science on the 5th of November 2022...

Airway obstruction by foreign bodies or laryngospasms often results in negative pressure pulmonary edema (NPPE). NPPE can develop despite the removal of airway obstruction. This is well-known among clinicians, particularly anesthesiologists, emergency physicians, pediatricians, and radiologists. Computed tomography (CT) features of NPPE include diffuse central ground-glass opacities and thickening of the bronchovascular bundles and bronchial walls. NPPE can also occur after strangulation or smothering with a plastic bag, and is sometimes fatal...

Abusive head trauma (AHT) is a leading cause of abusive deaths in children under age one. AHT can include intracranial hemorrhages, hypoxic ischemic injury, or parenchymal lacerations. Most infants with parenchymal lacerations present with acute neurological symptoms. There has been some published literature on lucid intervals in cases of AHT; however, there has not been a described lucid interval with parenchymal lacerations. Parenchymal lacerations typically present with acute symptomatology such as seizures, alteration in mental status, or increased fussiness/lethargy given the damage to neurons and brain structure...

INTRODUCTION: Knives are commonly-used weapons in criminal activities and interpersonal assaults worldwide. Injury reports have identified the upper body as the most frequent location of knife injuries, and that stabbing attacks are more fatal than slashing attacks. The first two aims of the study explore whether the type of attack and attack location could be predicted from age and sex group. The following aims compared attack times between sex and age groups and evaluated the influence of subject characteristics on attack duration...

Synthetic cannabinoids (SCs) represent a diverse class of new psychoactive substances characterized by extensive substance variety and severe abuse implications. The current situation of synthetic cannabinoid abuse in China is getting worse, with an increasing number of SC variants emerging. Therefore, it is imperative to improve synthetic cannabinoid detecting methods to align with the prevalent abuse situation in the region. In this study, a reliable and validated liquid chromatography-tandem mass spectrometry method was developed for the qualitative and quantitative analysis of 65 SC analogues in human hair samples...

Fibromuscular dysplasia of the coronary is an uncommon coronary defect with a range of pathological alterations and unpredictable clinical description that can cause sudden death. We present an autopsy case of sudden cardiac death due to a rupture of a coronary artery aneurysm in a 59-year-old woman. Postmortem autopsy revealed two huge saccular aneurysms located at the right coronary artery, one of which was ruptured leading to a fatal hemopericardium. Histopathological examination revealed coronary artery fibromuscular dysplasia with fibromyxoid dissociation of the media causing saccular aneurysms...

In forensic cases for which the time of death is unknown, several methods are used to estimate the postmortem interval. The quotient (Q) defined as the difference between the rectal and ambient temperature (Tr - Ta) divided by the initial difference (T0 - Ta) represents the progress of postmortem cooling: Q = (Tr - Ta)/(T0 - Ta), (1 ≥ Q ≥ 0). Henssge was able to show that with the body weight and its empirical corrective factor, Q can be reasonably predicted as a double exponential decay function of time (Qp(t))...

In forensic science and in modern times, impalement is a rare event. When this occurrence involves the head, it is even more unusual since this region is very small compared to the rest of the body. Although impalements are rare, they represent scenarios that must be treated with great care by forensic pathologists. They may involve a mixture of blunt and penetrating wounds, and the injuries observed at autopsy must be interpreted correctly. For this reason, if possible, the interconnection between the body and the impaling object should be maintained until the autopsy table...

Donepezil is one of the primary treatments options for patients suffering from Alzheimer's Disease. In a review of more than 2200 postmortem donepezil positive blood specimens, 76% of concentrations were higher than the proposed therapeutic range. Means and medians were similar between central blood specimens and peripheral specimens, indicating minimal postmortem redistribution. Postmortem concentrations may not reflect those circulating antemortem. Mean and median postmortem blood concentrations were approximately 3-fold higher than those in antemortem blood specimens...

South Africa is experiencing a scourge of violence against women and children, with alarming levels of violence, and as such, juvenile cases are sometimes encountered in a forensic anthropological setting. The aim of this research was to assess the cases of juveniles (under 20 years) presenting at the Human Variation and Identification Research Unit (HVIRU) for a 6-year period (2016-2022), in order to assess patterns and types of cases referred. A total of 19 cases were assessed, of which 10 were 16-20 years old, 3 between the ages of 5 and 15 years and 6 less than 5 years old at the time of death...
