A Systematic Review About Postmortem Pink Teeth: Forensic Classification, Diagnostic Value, and Analysis Methods.

The phenomenon of pink teeth represents a notable observation in forensic science, although its interpretation remains complex and not directly attributable to a specific cause of death. This systematic review provides an updated and comprehensive overview of the morphological and histological mechanisms associated with this finding, with a focus on hemoglobin diffusion and pigment accumulation during putrefaction rather than on detailed biochemical pathways. Environmental conditions, especially high humidity and moderate temperatures, are identified as key facilitators.

Application of bloodstain pattern analysis (BPA) to reconstruct a staged crime scene in a complex forensic case.

Bloodstain Pattern Analysis (BPA) constitutes a critical component of modern forensic science, particularly in complex crime scenes where the physical evidence may be manipulated or misinterpreted. This manuscript presents a detailed reconstruction of a residential scene initially suspected to be the site of a violent homicide. Despite extensive blood distribution across multiple rooms, forensic investigation revealed that the injuries sustained were superficial and incompatible with the volume and morphology of the bloodstains observed.

The Role of Autopsy in Diagnosing Fatal Chest Injuries in Road Traffic Accidents: A Literature Review.

Road accidents are one of the leading causes of death worldwide, with significant repercussions on public health and the global economy. Fatal accidents can cause injuries in various anatomical areas with different dynamics. The thorax is one of the main sites involved in fatal accidents, due to the presence of vital organs such as the heart and lungs.

Human Deaths Related to Oleander Poisoning: A Review of the Literature.

Oleander poisoning, resulting from the ingestion of Nerium oleander or Thevetia peruviana, is a serious toxicological issue in various parts of the world, particularly in regions where these plants grow abundantly and are easily accessible. Oleander contains potent cardiac glycosides, such as oleandrin and thevetin, which exert powerful effects on the cardiovascular system, leading to symptoms ranging from nausea and abdominal pain to severe arrhythmias and sudden cardiac death. This review summarizes the existing literature on the epidemiology, clinical features, pathophysiology, and challenges in treatment management associated with oleander poisoning.

Investigating the Post-Mortem Risk of Transmission of SARS-CoV-2 Virus in Cadaveric Tissues: A Systematic Review of the Literature.

The emergence of SARS-CoV-2, responsible for the COVID-19 pandemic, has prompted extensive research into its transmission dynamics; yet, a critical aspect that remains underexplored is the post-mortem infectivity of the virus within cadaveric tissues. Understanding the mechanisms by which SARS-CoV-2 maintains infectivity after death is essential, as it raises significant concerns regarding public health and forensic practices. Research indicates that the virus can persist in various tissues, including lung, liver, and kidney tissues, with studies showing that factors such as the time elapsed since death, the presence of underlying health conditions, and environmental conditions at the time of death can influence the level of infectivity in deceased individuals.

The Role of GFAP in Post-Mortem Analysis of Traumatic Brain Injury: A Systematic Review.

Traumatic brain injuries (TBIs) are a leading cause of mortality and morbidity, particularly in forensic settings where determining the cause of death and timing of injury is critical. Glial fibrillary acidic protein (GFAP), a biomarker specific to astrocytes, has emerged as a valuable tool in post-mortem analyses of TBI. A PRISMA-based literature search included studies examining GFAP in human post-mortem samples such as brain tissue, cerebrospinal fluid (CSF), serum, and urine.

Rapunzel Syndrome: Clinical, Diagnostic and Forensic Aspects in Related Deaths-A Review of the Literature.

Rapunzel syndrome is a rare and severe form of trichobezoar, characterized by the presence of hair masses in the stomach that often extend into the bowel, resembling the legendary "Rapunzel's" long hair. : This review examines the clinical, diagnostic, forensic, and post-mortem aspects associated with Rapunzel syndrome, with a focus on cases resulting in mortality or those at high risk of death due to complications. In particular, the review systematically analyzes the existing literature on fatal cases of Rapunzel syndrome, emphasizing insights into risk factors, clinical manifestations, diagnostic methods, autopsy findings, and preventive measures to provide a focused understanding of these critical aspects.

The Role of Adrenomedullin as a Predictive Marker of the Risk of Death and Adverse Clinical Events: A Review of the Literature.

Adrenomedullin (ADM) is a vasodilatory peptide that plays a crucial role in maintaining cardiovascular health through its various biological functions. ADM was discovered in the acidic extract of human pheochromocytoma tissue and has been recognized for its significant effects on the vascular system. The main functions of ADM include vasodilation, controlling blood pressure and maintaining vascular integrity, although its role on cardiovascular health is broader.
