"Was the Infant Born Alive?" A Review of Postmortem Techniques Used to Determine Live Birth In Cases of Suspected Neonaticide

Umbilical Cord Tissue: From Antemortem Monitoring to Postmortem Possibilities

ABSTRACT

Umbilical cord tissue (UCT) traditionally has been used as an antemortem matrix for identifying and monitoring fetal exposure to drugs suspected to have been used during pregnancy. The specimen offers several advantages as a testable tissue, including accessibility and ease of collection, ample sample volume, a long window of detection, and ability to detect for a wide range of drugs. Despite these advantages, little to no research exists on the use of UCT as a postmortem forensic toxicology specimen. This article aims to provide insights into UCT toxicological testing and infer potential applications for postmortem use, such as investigations into stillbirths and infant abandonment. Umbilical cord tissue offers several benefits as a postmortem toxicological specimen. Importantly, it can be collected with or without an autopsy being performed and may help explain factors that contribute to the underdevelopment and death of the neonate. With the limited sample volumes present in infant investigations, toxicological analysis of UCT could become a valuable tool for neonatal medicolegal death investigations.

Useless and limits of Postmortem CT (PMCT) in a complex case of preterm infant murder

The present case-report empathizes the usefulness of post-mortem computed tomography (PMCT) in the detection of live birth signs in a baby found dead, comparing the results with standard autoptic, histologic and immunohistochemical examinations. The report describes the case of a new-born who was thrown out on the footpath from a window of the fifth floor according to the investigative police, whilst the mother has hidden herself immediately after childbirth. PMCT showed diffusely aerated lung parenchyma with signs of severe lung distress, air in the airways with no fluid inside, and air in the upper gastro-intestinal tract, in absence any resuscitation manoeuvres performed on the baby at delivery. PMCT underlined multiple fractures of the skull with degeneration of cerebral parenchyma. All these findings were confirmed by conventional autopsy and histological and immunohistochemical examinations, clinching the usefulness of PMCT in differentiating live births from stillbirths.

Medicolegal Evaluation of an Abandoned Dead Neonate: A Case Report

Introduction: The killing of an illegitimate newborn immediately or within 24 hours of birth is neonaticide which differs from other forms of homicide in terms of diagnosis and motives. Neonaticide is a cognizable offense where mothers are usually the perpetrators. This case reports the autopsy findings of a smothered neonate at a secluded location in rural Nepal. The present case study also highlights the medicolegal implications in such cases.
