Sex differences from fingerprint ridge density in the Indian population

Determination of individuality is one of the prime concerns in forensic investigation. The study of fingerprints is widely used in providing a clue regarding identity. The present study was undertaken to study the sex differences in fingerprint ridge density in the Indian population. The study done on 100 males and 100 females revealed that significant sex differences occur in the fingerprint ridge density. The present study shows a statistically significant difference in fingerprint ridge densities of male and female fingerprints in people of Indian origin. A mean fingerprint ridge density of 12 ridges/25 mm(2) or less is found to be more likely to be of males and a mean ridge count of more the 12 ridges/25 mm(2) is more likely to be of female origin.

Toxicoepidemiology of fatal poisonings in Southern India.

An autopsy based retrospective study was conducted from January 2000 to December 2006 at Manipal in Southern India, and a profile of the victims of poisoning was prepared. The study was done to understand the magnitude and pattern of all poisoning fatalities in relation to the manner of death in Manipal region of Southern India. The study included a total of 198 cases of fatal poisoning. Self-poisoning was reported in 92.9% cases. Fatal accidental poisoning was seen in 6.1% cases. Homicide by poisoning was not reported during the study period. Uncertainty regarding the manner of death due to poisoning was observed only in two cases. Males were predominantly affected (71.2%). The majority of the victims were in the 3rd decade (28.3%) of life. The age of the victims ranged from 2 to 82 years with a mean age of 38.4 years. While majority of the victims consumed poison during daytime, most of the poisoning fatalities were reported during summer months. Organophosphate compounds were implicated in 68.7% of the total poisoning related fatalities. Males in the 3rd to 5th decades were prone to self-poisoning with organophosphate compounds. Accidental poisoning deaths were uncommon and poisoning was not a preferred method of homicide in this region. Our approach to the study reveals that quantitative chemical (toxicological) analysis is required to further strengthen and improve the databases of epidemiology of poisoning in our region.

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.

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.

Fatal Craniocerebral Injury from Wild Boar Attack

Figure 1. Abrasions and puncture wounds on the thighs. There has been and will continue to be proactive communication on behalf of the Society with program directors and medical school deans to inform them of our resources, in both curricula material and speakers. The ability of educators, residents, and students to connect with each other has been expanded through use of the WMS site, which not only facilitates communication but also provides a way to assess the demographics of wilderness medicine education. There has been and will continue to be efforts made to reach out to other academic groups to create practice standards, as well as influence curricula. We are engaged with creating a joint statement on practice standards with the wilderness medicine subsection of the American College of Emergency Physicians. All these steps represent a new and exciting time in the evolution of our field and will further promote the WMS as its sole academic body and as a viable academic clearinghouse for students and future practitioners.

Postmortem diagnosis of acute haemorrhagic pancreatitis

Forensic pathologists can help in the investigation of sudden unexpected deaths in co-operation with the officials responsible for the maintenance of law and order to administer justice. Sudden unexpected deaths form the subject of medicolegal investigation if they occur in apparently healthy individuals, wherein an autopsy would shed light regarding the cause of death. A 4 year retrospective review of autopsy files at the Department of Forensic Medicine, Kasturba Medical College, Mangalore, South India was undertaken for cases of sudden unexpected deaths due to acute haemorrhagic pancreatitis occurring between May 2004 and April 2008. A total of seven cases of acute haemorrhagic pancreatitis diagnosed at autopsy as the cause of sudden unexpected death during the study period are discussed herein.

“Atypical Suicidal” cut throat injury – A case report

Suicide is one of the leading causes of death in the world. The incidence and pattern of suicide vary from country to country. Cultural, religious and social value plays a vital role. Hanging, poisoning, drowning are the common methods of committing suicide. Suicide by incising ones own throat without hesitation marks remains a rare, and only few cases have been reported in the forensic literature. We present here an unusual and rare case of self-inflicted cut throat injury of a 45-year old ex-military man without tentative cuts over the neck, which has resulted from a curved sharp weapon.

Acute haemorrhagic pancreatitis – A case of sudden death

Sudden death in young individuals is relatively uncommon and acute haemorrhagic pancreatitis as a cause of sudden and unexpected death is a rare phenomenon. A case of sudden death due to acute haemorrhagic pancreatitis is reported in a young doctor who ignored the radiating pain of acute pancreatitis for gastritis, and resorted to self-medication. The condition was discovered only at autopsy.

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.
