In India, it is estimated that about 13 million people are homeless. As these individuals have no close acquaintances, in the event of death, their bodies remain unclaimed. These unclaimed corpses pose a major challenge for the local law enforcement agencies in identification and thus become an obstacle in solving the cases of missing persons. We sought to review the autopsy characteristics and causes of death in the unclaimed/unidentified bodies autopsied at the All India Institute of Medical Sciences (AIIMS) from 2006 to 2012. Among the total of 11,786 cases autopsied during the year 2006 to 2012, 1335 (11%) were unclaimed. Most of the cases were males (91%) with a male-to-female ratio of 9:1. Mean age of the cohort was 43 years (range, 1-85 years). Natural events were the foremost cause of death and were more commonly seen in males. While accidental, suicidal and homicidal modes were common in younger age groups; natural manner of death predominated in the elderly. Most of the cases were found dead on the roadside. This paper also compares with the previous study in the same set-up during the time period 2001 to 2005. The authors believe that knowledge about the existing healthcare facilities need to be reinforced and their utilisation promoted.
The presence of several osteogenic molecules in caudate nucleus indicates that BGC would probably be the outcome of an active process. The differences in expression of these molecules in caudate over gray matter could favor BGC at this site in the unique biochemical milieu of hypoparathyroid state.
Context:The appropriate collection and preservation of soft tissues from putrefied unidentifiable human corpse for the purpose of identification using DNA profiling technique is critically important especially in developing countries like India having different levels of health-care set ups with largely varying facilities and varying climatic conditions.Aims:The present study was carried out, mainly focusing on quality and quantity of extracted DNA from the soft tissues of putrefied unidentifiable human corpse stored upto 4 weeks at 4°C and at −80°C for DNA analysis.Materials and Methods:The present study was conducted on 16 different putrefied unidentifiable human corpses after getting approval from institutional ethical committee. Around 2 g of four different tissues (brain, kidney, heart and muscle) were collected and preserved for one month followed by DNA extraction using the organic method, the quality and quantity of high molecular weight-DNA was estimated using the spectrophotometer and gel electrophoresis. Further, the amplification polymerase chain reaction (PCR) was also performed (AmpFLSTR® Indentifiler™ PCR Amplification kit for multiple loci, of Applied Biosystems, Lab India) and was checked using continuous PAGE.Results:The yield of DNA was significantly higher at −80°C for all the four tissues collected and was best for brain followed by heart, kidney and worst for muscles in all cases.Conclusions:It is suggested that the brain tissue preserved at −80°C is the best among soft issues for DNA extraction. Refrigeration or deep freezing facility should be available at all the centers.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
