Résumé
Estimation of post mortem interval is of great importance in both civil and criminal disputes. Determining time since death is extremely difficult and accuracy can never be met. Most of the methods currently employed are temperature based algorithms, rigor mortis, livor mortis, thanato-chemistry etc. But the uncertainties attaching to traditional means of establishing the time since death have directed attention to the chemical changes in the body fluids like cerebrospinal fluid and vitreous humour along with various cellular changes in the body tissues. The study of the viability and morphological changes seen in the cells of various body tissues could provide useful information regarding post-mortem interval. In our study the cellular and cytoplasmic changes observed were time related up to 16 hours.
Résumé
The present research aims to highlight the pattern of thoraco-abdominal injuries sustained by the victims of fatal road traffic accidents (RTA) in Manipal, South India. The study is an autopsy based observation of thoraco-abdominal injuries in victims of fatal road traffic accidents during 1999 – 2003. Road traffic accidents accounted for most of the injury related deaths (77%) during the study period. A male preponderance (86%) was observed with a male-female ratio of 6:1. Individuals in the age group of 21 to 50 years formed the most vulnerable (83%) group. External thoracic injuries were more common than internal thoracic injuries in the thoracic region. In the abdominal region, internal injuries were more common than external injuries. Lungs (61%) and kidneys (23%) were the most commonly involved organs in the thoracic and abdominal regions respectively. Majority of the victims were two wheeler occupants (35%) followed by pedestrians (23%). The study indicates the pattern of thoraco-abdominal injuries sustained along with the trend of road traffic accidents in the region.
