Introduction

This study analyzed sudden deaths in young adults (18-35 years old) via forensic autopsy in Greece over a five-year period. Key findings highlighted cardiovascular diseases as the predominant cause, emphasizing the critical role of comprehensive medico-legal investigation in establishing cause of death, especially when no prior medical history exists. The research underscores the need for standardized autopsy protocols to accurately identify underlying pathologies and inform public health strategies.[1].

This review article meticulously examines the postmortem distribution and toxicological significance of new psychoactive substances (NPS). It highlights the challenges in detecting and interpreting NPS concentrations in various biological matrices due to their diverse chemical structures and rapid metabolism. The paper provides crucial insights for forensic toxicologists, emphasizing the need for advanced analytical techniques and comprehensive interpretative frameworks in medico-legal death investigations involving NPS.[2].

This cross-sectional survey investigated Turkish physicians' knowledge, attitudes, and practices concerning medical malpractice and legal medicine. The study revealed significant gaps in understanding legal responsibilities and processes, highlighting a need for improved medical education and continuous training on medico-legal issues. Such initiatives are crucial for reducing malpractice risks and enhancing patient safety within the healthcare system.[3].

This review article explores the critical role of forensic anthropology in identifying human remains following mass fatality incidents. It discusses current methodologies, including osteological analysis, craniofacial reconstruction, and DNA integration, highlighting the challenges posed by degraded remains and fragmented contexts. The authors emphasize the need for interdisciplinary collaboration and advanced techniques to improve identification rates and support legal and humanitarian efforts in such complex scenarios.[4].

This article delves into the complexities of assessing criminal responsibility in offenders with mental disorders, a cornerstone of forensic psychiatry. It meticulously outlines the inherent challenges, such as diagnostic ambiguities, cultural factors, and varying legal frameworks, while proposing practical solutions. The authors advocate for comprehensive evaluations, multidisciplinary collaboration, and ongoing professional development to ensure fair and accurate medico-legal determinations in such cases.[5].

This systematic review provides an updated overview of postmortem computed tomography (PMCT) in forensic practice, highlighting its increasing integration and value as an adjunct to traditional autopsy. The review synthesizes evidence on PMCT's capabilities in detecting traumatic injuries, identifying foreign bodies, and characterizing natural diseases, especially in cases where conventional autopsy is challenging or restricted. It emphasizes PMCT's role in improving diagnostic accuracy and efficiency in medico-legal investigations.[6].

This review critically examines the forensic aspects and medico-legal challenges associated with child abuse and neglect. It discusses the complexities of identifying non-accidental injuries, differentiating them from accidental trauma, and navigating the legal implications of such findings. The article underscores the crucial role of forensic pediatricians and multidisciplinary teams in evidence collection, interpretation, and expert testimony to ensure justice for child victims.[7].

This comprehensive review highlights recent advancements in forensic DNA analysis crucial for human identification in medico-legal contexts. It covers innovations in techniques like next-generation sequencing, Y-STR analysis, and mitochondrial DNA profiling, which enhance resolution and sensitivity, particularly for degraded or limited samples. The article also discusses the evolving statistical interpretation of DNA evidence, underscoring its pivotal role in criminal investigations and disaster victim identification.[8].

This article addresses the significant challenges in conducting effective forensic death investigations within resource-limited settings. It identifies issues like inadequate infrastructure, lack of specialized personnel, and limited access to advanced technologies. The authors propose practical and sustainable solutions, including capacity building, regional collaborations, and simplified protocols, to enhance the quality and reliability of medico-legal death investigations globally.[9].

This review explores the evolving field of forensic odontology, focusing on its critical role in human identification, particularly in mass disasters and cases involving heavily decomposed or fragmented remains. It discusses conventional methods like dental record comparison, along with advancements such as 3D imaging and AI integration. The article also addresses the controversies surrounding bite mark analysis, advocating for evidence-based practices and continuous methodological refinement in medico-legal investigations.[10].

Conclusion

Forensic science plays a crucial role in various medico-legal investigations, encompassing diverse specializations. Studies highlight the importance of forensic autopsy in determining the cause of sudden deaths in young adults, often revealing underlying cardiovascular diseases and emphasizing the need for standardized protocols. Challenges exist in detecting and interpreting new psychoactive substances (NPS) postmortem due to their complex pharmacology, necessitating advanced analytical techniques for forensic toxicologists. Legal medicine also addresses the knowledge gaps among physicians regarding medical malpractice, underscoring the need for continuous education to enhance patient safety and reduce legal risks. Beyond clinical applications, forensic anthropology is vital for identifying human remains in mass fatality incidents, employing osteological analysis, craniofacial reconstruction, and DNA integration. The field also grapples with assessing criminal responsibility in mentally disordered offenders, calling for comprehensive evaluations and multidisciplinary collaboration within forensic psychiatry. Technological advancements are transforming forensic practices, with postmortem computed tomography (PMCT) becoming an increasingly valuable adjunct to traditional autopsies, improving diagnostic accuracy for injuries and diseases. Similarly, breakthroughs in forensic DNA analysis, including next-generation sequencing and Y-STR profiling, are enhancing human identification capabilities for degraded or limited samples, critical for criminal investigations and disaster victim identification. Furthermore, forensic odontology continues to be essential for identification, especially in mass disasters, using dental records and advanced imaging, though it faces ongoing debates, particularly around bite mark analysis. Investigations into child abuse and neglect also present significant medico-legal challenges, requiring specialized forensic pediatricians and team efforts for evidence interpretation. Finally, resource-limited settings globally face substantial hurdles in conducting effective forensic death investigations, prompting calls for capacity building and simplified protocols to ensure quality and reliability in medico-legal processes.
