Stature estimation from the length of the sternum in South Indian males: A preliminary study☆

Estimation of stature is one of the important initial steps during forensic analysis of human skeletal remains. The aim of the present study was to derive a linear regression formula for estimating stature of adult South Indian males from the length of the sternum. The study included 35 male sternums of South Indian origin dissected from cadavers during medico-legal autopsies. The linear regression equation [Stature=117.784 + (3.429 x Sternal length)] was derived to estimate the stature from the length of the sternum. The correlation coefficient was 0.638. The standard error of the estimate was 5.64 cm. This preliminary study concludes that the length of the sternum can be used as a tool for stature estimation in adult South Indian males.

Estimation of stature from cranial sutures in a South Indian male population

The aim of this study was to investigate the possibility of estimating height from length of coronal and sagittal sutures of the skull for the positive identification of the height in forensic investigations concerned with fragmentary skeletal remains. The study was conducted on 87 male bodies subjected to medicolegal autopsy in the Department of Forensic Medicine, Kasturba Medical College, Manipal, South India and the Department of Forensic Medicine, Kasturba Medical College, Mangalore, South India. Length of coronal suture was measured from left pterion at the junction of sphenoparietal with the sphenofrontal suture, along the coronal plane, over the coronal suture to the pterion on the right side. Length of sagittal suture was measured from bregma along the sagittal plane over the sagittal suture to the lambda. The data collected were subjected to statistical methods. Significant correlation was found between height and coronal suture length in males, when compared to sagittal suture. The correlation coefficient between height and coronal suture was 0.363. The correlation coefficient between height and sagittal suture was 0.090. Linear regression equations for stature estimation were derived from coronal suture length in male population. Coronal suture length gives more accurate results in estimating stature than sagittal suture. However, in cases where identification is required by means of only skull, this method could prove useful.

Sexual dimorphism of the index to ring finger ratio in South Indian adolescents.

Sex determination from prepubertal human remains is a challenge for forensic experts and physical anthropologists worldwide as definitive sexual traits are not manifested until after the full development of secondary sexual characters that appear during puberty. The research was undertaken in 350 South Indian adolescents to investigate sexual dimorphism of the index and ring finger ratio. The index finger length (IFL) and the ring finger length (RFL) were measured in millimeters in each hand and the index and ring finger ratio was computed by dividing the index finger length by the ring finger length. Mean RFL was greater than mean IFL in both males and females. Mean RFL was significantly higher in males. The index and ring finger ratio showed a statistically significant difference between males and females (p </= 0.001). The index and ring finger ratio was found to be higher in females (0.99) when compared to their male counterparts (0.95). The index and ring finger ratio thus shows sexual dimorphism in the South Indian adolescents that may prove useful to determine the sex of an isolated hand when it is subjected for medicolegal examination. The study suggests that a ratio of 0.97 and less is suggestive of male sex, while a ratio of more than 0.97 is suggestive that the hand is of female origin among South Indian adolescents.

Objective structured practical examination (OSPE) in Forensic Medicine: students' point of view.

The purpose of this study was to assess the attitudes of undergraduate medical students towards the objective structured practical examination (OSPE) in Forensic Medicine, in a medical college in Nepal. Participants included 59 undergraduate medical students of the 7th semester. Findings indicated that the OSPE was an acceptable tool considering the conduct of practical examination in Forensic Medicine at the undergraduate level. The overall mean attitude score was towards the favourable side. Students strongly agreed that the OSPE tested a wide range of skills. They also strongly agreed that it was a good form of examination as well as a learning experience. The introduction of the OSPE replacing the conventional method of practical examination in Forensic Medicine is a step in the right direction taken to objectively assess undergraduate medical students.

An Autopsy Case of Sudden Unexplained Death Caused by Malaria

Abstract:  Sudden unexplained deaths, especially those unwitnessed can lead to forensic issues and would necessitate the need for a meticulous and complete postmortem examination including ancillary investigations to discover the cause of death. We herein report a case of sudden unexplained death caused by malaria in an apparently healthy individual. This fatal case is presented to remind the forensic pathologist of the possibility of malaria as a cause of sudden unexplained death in malaria‐endemic regions. In the present case, histopathological examination demonstrated the presence of parasitized red blood cells with malarial pigment in the blood capillaries in the brain, myocardium, pericardium, lungs, kidneys, liver, and the spleen. Cerebral malaria with acute renal insufficiency or pulmonary edema with an acute respiratory distress syndrome might have been the cause of death.

Bilateral calcified stylohyoid ligament: an incidental autopsy finding with medicolegal significance.

Eagles syndrome occurs due to elongation of the styloid process or calcification of the stylohyoid ligament, which then may produce a pain sensation due to pressure exerted on various structures in the head and neck region. A case report of calcified stylohyoid ligament found incidentally at autopsy and further confirmed by computed tomography scan and histopathology is herein discussed with associated medicolegal significance.

Traumatic degloving lesion of male external genitalia

Injury to the male external genitalia is relatively uncommon when compared with other parts of the human body. Trauma to external genitalia could result from accidents involving motor vehicles, power farm machinery, gun shot and stab injuries. We present a rare case of traumatic degloving injury of male external genitalia associated with partial penile amputation and loss of both testes sparing the internal abdominal and pelvic organs, resulting from run over by a heavy vehicle tyre.

Forensic evaluation of occupational marks in establishing identity—A case report

The livings have responsibilities for the dead; and in particular, civilized societies recognize the need for identity both during life and at death, particularly in circumstances when an unknown body is summoned for medico-legal autopsy. There are numerous tools for identification of an unknown body which includes visual identification, fingerprints, medical prostheses, odontological techniques, DNA fingerprints and to include in the list is the occupational marks over the body sustained during the course of his or her profession. The medico-legal investigators should possess comprehensive knowledge of such occupational marks, which aid in identification. We are highlighting a case of rare entity, where a forensic evaluation of occupational marks was done to establish the identity of an unknown elderly male, who committed suicide by ligature hanging.

Male external genitalia injury caused by ‘elephant stampede’

We report an unusual and rare cause of male external genitalia injury, caused by an elephant stampede. The incident occurred when the unfortunate victim was attending a �call of nature� early one morning in the coffee plantation estate adjacent to his residence in Coorg District of Karnataka State, India. The patient sustained injuries to the left chest and left thigh, as well as a degloving scrotal injury on the right side. Language: en

Adenomyomatous polyp of the uterus: Report of an autopsy case and review of the literature

Adenomyomatous polyps of the endometrium are a rare subtype of endometrial polyps. In addition to the usual features of endometrial polyps, they also contain a smooth muscle component. Grossly they appear no different than ordinary endometrial polyps. In the case reported herein, a 23-year-old nulliparous female was killed in a traffic accident. In the course of the medicolegal autopsy, a small pedunculated growth was identified in the fundus of the endometrial cavity. Histologically the mass consisted of endometrial glands intimately mixed with smooth muscle and thick walled blood vessels, consistent with an adenomyomatous polyp. There was no history of tamoxifen use in this individual. To our knowledge this is the first report of post-mortem diagnosis of an adenomyomatous polyp. Furthermore, this is the first report of an individual with this diagnosis younger than the fourth decade. In the medicolegal setting, forensic pathologists are constantly faced with entities that, while they may not have caused death, may serve to educate practitioners about rare lesions. This individuals finding serves as one of those entities. This case reiterates the importance of the autopsy as not only the answer to an individuals death, but as an avenue for the discovery of entities that may have relevance to those who are still living.
