On August 30th, 2024, a specialized workshop on Thanatology was organized for 25 final-year students at Father Muller Medical College. This event was conducted as part of the ongoing Memorandum of Understanding (MoU) between our institution and Father Muller’s, aimed at fostering academic collaboration and enhancing forensic education. The session was led by Dr. Thanush Shetty, an Assistant Professor of Forensic Medicine and Toxicology, who delved into the scientific study of death and the various post-mortem changes that occur in the human body.
Dr. Thanush began by introducing students to different types of death. He explained the distinctions between somatic death, which marks the cessation of bodily functions, and cellular death, which pertains to the death of individual cells. He also introduced the concept of suspended animation—a temporary cessation of vital functions that can mimic death. Understanding these distinctions is crucial in both medical and forensic contexts to avoid premature declarations of death, which could have significant legal and ethical implications.
The workshop also covered the Harvard criteria for determining brainstem death, which is essential in diagnosing legal death, particularly in cases involving life support and organ donation. Dr. Thanush highlighted the importance of these criteria in ensuring ethical and accurate death determinations. He further discussed the complexities of conducting autopsies, with a focus on negative autopsies, where no cause of death is found, and obscure autopsies, where the cause remains undetermined despite thorough investigation.
In addition to theoretical discussions, Dr. Thanush provided an in-depth overview of the signs of death, categorizing them into immediate, early, and late signs. Immediate signs include the cessation of respiration and circulation, while early signs involve physical changes such as rigor mortis (stiffening of the muscles) and algor mortis (cooling of the body). Late signs encompass putrefaction, mummification, and adipocere formation, each of which has specific characteristics and timelines that are vital for estimating the time of death and understanding the circumstances surrounding a death.
The session also explored various post-mortem changes, including marbling (the appearance of a marbled pattern on the skin due to blood decomposition), post-mortem purge (release of bodily fluids), and maggot activity, all of which are crucial in forensic investigations for determining the time since death and reconstructing post-mortem intervals. Dr. Shetty also discussed Casper’s Dictum, a principle used to estimate the time of death based on decomposition rates in different environments, and examined the conditions under which phenomena like mummification, adipocere formation, and skeletonization occur.
To enhance understanding, Dr. Thanush incorporated post-mortem videos into the workshop, demonstrating various stages of decomposition and other post-mortem changes. These visual aids provided students with practical insights into the physical processes of death, such as rigor mortis, algor mortis, and putrefaction. The videos also illustrated how environmental conditions and other factors influence the rate and nature of these changes, making the session both engaging and informative.
Throughout the workshop, Dr. Thanush encouraged active participation from the students, fostering an interactive learning environment. He addressed their questions and clarified their doubts, ensuring a clear understanding of the complex concepts discussed. This interactive approach not only enhanced the students' grasp of thanatology but also deepened their appreciation of its critical role in forensic investigations.
Overall, the workshop significantly enriched the students' knowledge of thanatology, providing them with a comprehensive understanding of the various stages of death and the post-mortem changes that are fundamental to forensic science. The session served as a valuable learning experience, equipping future forensic professionals with the knowledge and skills necessary for accurate death investigations.
