A Forensic Autopsy Study of Dead Foetuses and Newborns

Background: The term abandonment refers to babies or foetuses which are found abandoned at various unwanted places such as gutter, rubbish dumps, railway tracts and bushes. It does not refer to live born babies left in places, such as hospitals where care can be given by someone other than the mother. Aims and Objectives: To find out the distribution of death cases of newborns/feotuses and to trace its probable reason and its relationship with female foeticide.Methods:A retrospective study of all the medico-legal autopsies of foetuses and newborns was conducted in Forensic medicine and Toxicology department, Government Medical College, Amritsar (Punjab) from Jan 1, 2014 to Jul 31, 2021. During this period, 46 cases of fetal and newborn deaths had been studied.Results:The dead bodies of known foetuses/newborns is 43.5% cases while total unknown cases were 56.5% cases. 32.6% cases were non viable foetuses while 10.8% cases died as a result of prematurity. All the unknown cases (56.5%) were found from the abandoned places like street, bushes, canal side, water bodies that mainly includes pond and railway tract.Conclusion:Despite, the problem is present in every corner of the nation, there is dearth of research studies on this issue. Stringent measures and strict checks are required against antenatal sex determination. The motive behind the abandonment of foetuses can be any, but this grave issue needs urgent attention.

Mites occurring in farm buildings as allergic agents and indicators in forensic analyses

Storage mites, especially several species in the families Acaridae, Glycyphagidae, and Chortoglyphidae are commonly found in farming and occupational environments. They are a source of clinically important allergens, and may also have a significant impact on forensic analyses. They may be of use in forensic situations, particularly as allergenic taxa, in relation to workers who are occupationally exposed to mites. Additionally, because many of them are present through all stages of vertebrate decomposition, they may provide valuable information as indicators of time and circumstances of death. This study aimed to investigate the possible occurrence and abundance of allergenic mites in farm buildings, as well as to examine and analyse collected material samples in relation to forensic medicine. A total of 58 samples from 15 farms in the Żywiecki district (Silesian Province, Poland) were examined as potential sources of allergenic mites in farm buildings with a special reference to forensic acarology. Mites were found in all the examined samples. A total of 4,473 specimens were isolated and 22 mite species were identified. Most of them were found in barns and pigsties. The species composition of the acarofauna was varied across the particular types of farm buildings examined. Generally, the dominant species were representatives of families Acaridae and Glycyphagidae (Astigmatina). This knowledge may be useful in a variety of cases or situations in the field of forensic medicine.

South African and international legislature with relevance to the application of electronic documentation in medicolegal autopsies for practice and research purposes

Background Forensic and legal medicine requires all documentation to be recorded in a manner that is admissible in court. Issues surrounding privacy, confidentiality, and security mar the implementation of electronic document systems in medicine. Awareness of current legislature governing record keeping and electronic documentation especially in modern medicine and forensic medicine has not been sufficiently explored. This study explored the current South African and international laws that govern admissibility of evidence, especially relating to electronic evidence, for use in court and research, Findings Egypt, UK, Canada and the USA have similar legislation to South Africa regarding admissibility of electronic records. The South African Electronic Communications and Transactions Act no. 25 of 2002 defines data and the Criminal Procedure Act 51 of 1977 further defines the admissibility of evidence in court and the National Health Act regulates publication of deceased information after death. Conclusions Forensic medicine requires all documentation to be admissible in court and the storage of data thus requires proper custodianship and a high level of security, which can be achieved with modern technology. Modern medicine is evolving and technology can create secure and efficient methods of record keeping which will benefit forensic and legal medicine. Knowledge of the laws regarding admissibility of evidence can assist in creating electronic evidence that is permitted in court and can be used for research.

Age Estimation from Left-Hand Radiographs with Deep Learning Methods

Bone age is estimated in pediatric medicine for medical and legal purposes. In pediatric medicine, it aids in the growth and development assessment of various diseases affecting children. In forensic medicine, it is required to determine criminal liability by age, refugee age estimation, and child-adult discrimination. In such cases, radiologists or forensic medicine specialists conduct bone age estimation from left hand-wrist radiographs using atlas methods that require time and effort. This study aims to develop a computer-based decision support system using a new modified deep learning approach to accelerate radiologists' workflow for pediatric bone age estimation from wrist radiographs. The KCRD dataset created by us was used to test the proposed method. The performance of the proposed modified IncepitonV3 model compared to IncepitonV3, MobileNetV2, EfficientNetB7 models. Acceptably high results (MAE=4.3, RMSE=5.76, and R2=0.99) were observed with the modified IncepitonV3 transfer deep learning method.
