3D CT based age estimation from the pubic symphyseal surface in an Indian population using the Chen et al. method.

The pubic symphyseal surface is one of the reliable parameters used to estimate age, as it consistently shows degenerative observational variations throughout the lifespan, particularly from the 3rd decade onwards. These changes have been extensively studied to generate population-specific models for forensic age estimation. In the past, there have been many studies used to estimate age at death from the pubis symphysis using skeletal remains. However, due to dearth of contemporary skeletal repositories, and the resource intensive maceration process required for obtaining examination quality bones, studies on cadaver are difficult to conduct. Moreover, due to recent advancements in the science of medical imaging, newer radiological modalities like computed tomography (CT) can be used to visualize previously inaccessible areas such as the pubic symphysis in cadavers and the living alike, and subsequent age estimation is feasible. Recently, Chen et al. (2008, 2011) conducted a study on the cadaveric Chinese Han population in both males and females separately by using nine morphological changes and scoring them according to the changes that occurred. The present study aimed to estimate an individual's age using CT images of the pubic symphysis, by applying the scoring method for its morphological changes given by Chen et al. The present study was conducted on 263 randomly selected participants (Males = 154, Females = 109), who came for diagnostic purposes to the hospital. The CT images of these individuals were collected after obtaining ethical approval and proper consent from the study participants. Each of the morphological indicators was assessed, and appropriate scores were given according to criteria given by Chen et al. In the present study, both linear and multiple regression models to estimate age using the pubic symphyseal morphological changes were developed. From the results of the present study, it was concluded that the Chen et al. scoring method can be used to accurately estimate age from 3DCT images of the living, and the models derived in the present study could be applicable to individuals from the Indian subcontinent.

An Unusual Attack by a Blue Bull Resulting in Penetrating Horn Injuries.

Owing to multiple factors, human-wildlife interactions are increasing, and conflict can result in fatal injuries. A 21-y-old man was brought to the emergency department in critical condition with 2 puncture wounds over the thoracoabdominal region after a nilgai, or blue bull (Boselaphus tragocamelus), had gored him. The patient sustained double gastric perforation, which was managed laparoscopically and complicated by an abscess formation in the lesser sac 1 wk later, which required further surgical exploration. The operative culture showed growth of Klebsiella pneumoniae. Intravenous antibiotics were given as per the culture sensitivity report, and the patient improved. Many horn injuries are described as puncture lacerated wounds owing to the rugged nature of animal horns. However, in this case, the margins of the wound were regular and incision-like owing to the smooth and straight structure of blue bull horns. Early surgical exploration and monitoring of treatment progress are crucial in reducing morbidity in penetrating horn injuries.

Filicide-suicide: An unusual variant of dyadic death.

Dyadic suicides may be committed simultaneously or one after another by two or more people who may or may not have made a prior pact. The perpetrator is usually male and their victims female, and generally their intimate partners, with children less commonly involved. Another distinct type of homicide-suicide is the killing of children by a parent (filicide-suicide). The terms 'maternal filicide' or 'paternal filicide' are used respectively when the perpetrator is the mother or the father of the victim. We report a rare case of maternal filicide, where the mother drowned her three children and then herself in the same water tank. The case highlights the extreme stress put on a mother of girls in a patriarchal society where there is an overriding expectation and wish for sons. The resulting pressure on this mother for her 'failure' caused her to take her own and her children's lives.
