RESUMEN

The renowned work of Clyde Snow and the development of the Equipo Argentino de Anthropología Forense (EAAF) team has inspired the use of forensic anthropological and archaeological skills in human rights interventions around the world. Whether for medico-legal intervention and acquisition of evidence or humanitarian repatriation and identification of human remains, forensic expertise has garnered attention in the global arena. Arguably fulfilling evidentiary and psychosocial needs, there has been growing interest in this post-conflict redress. However, as part of the critique of these interventions, scholars and practitioners have pointed out - primarily in medico-legal investigations - a lack of sensitization of local communities regarding forensic work, increasing the potential for re-traumatization, unrealistic expectations, or an unintentional increase in political tensions. Research regarding forensic intervention and human remains have permeated social sciences, peace and conflict studies, and science and technology studies, revealing both intentional and unintentional impacts of forensic sciences after mass violence. In an effort to mitigate negative impacts of medico-legal or humanitarian interventions, the research described here sought to sensitize communities in Uganda about forensic methods. Findings from this study suggest that sensitization is necessary and desired, and that a multi-step approach can assist in managing expectations.

RESUMEN

Sudden unexpected death is an upsetting event, which can remain unexplained even after post-mortem investigation. Internationally, molecular autopsies have shown to resolve up to 44% of unexplained cases; however, it is currently unclear how many of these were infants. This systematic literature review showed that significantly fewer infant cases were resolved (median: 4%) compared with cohorts of 1 to 45 years old (median: 32%). Further, no study involving indigenous African participants has yet been published. Overall, molecular autopsies hold immense value to living family members and is motivation to explore new avenues in infant cohorts.

RESUMEN

Forensic entomology aids the determination of post mortem interval based on arthropods associated with a deceased body. This relies on the accurate identification of insects that visit the body, particularly first colonisers such as Calliphoridae (Diptera). Traditional species identification though morphological keys can be challenging as immature or closely related specimens can look similar. Some of these challenges have been overcome through "DNA barcoding", which involves the sequencing of informative regions within a species' DNA and comparison to a database of reference sequences. However, reference DNA sequences of blow fly species in South Africa is currently limited. In this study, adult blow flies representing four species common to the Western Cape, South Africa (Chrysomya chloropyga, Chrysomya albiceps, Chrysomya marginalis, Lucilia sericata) were examined using morphological keys and DNA barcoding of two regions: COI and ITS2. These DNA sequences were then used as references for the successful identification of seven unknown immature specimens. Intraspecific divergence showed a maximum of 0.36% and 2.25% for COI and ITS2, respectively; interspecific divergence showed a minimum of 6.14% and 64.6% for COI and ITS2, respectively. According to these results, COI and ITS2 have sufficient discriminatory power for species-level identification for the four species studied.

RESUMEN

Death due to infectious diseases is a major health concern worldwide. This is of particular concern in developing countries where poor-socio economic status and a lack of healthcare resources contribute to the high burden of disease. In some cases death due to infection can be acute and aggressive, and death may occur without a diagnosis whilst the person is still alive. These deaths may ultimately lead to a medico-legal autopsy being performed. There are various mechanisms by which sudden death due to infection may occur. In addition, there are many risk factors associated with sudden death due to infection, which differ between infants and older individuals. However, it is unclear which pathogens and risk factors are most frequently associated with sudden death due to infection. Therefore a systematic review of articles and case reports published between 1 January 2000 and 30 June 2016 was undertaken in order to (1) explore the relationship between pathogens and their causative role and (2) identify the relationship between predisposing and/or risk factors associated with sudden death due to infection. Major databases were searched and after critical appraisal 143 articles were identified. It was found that respiratory infections and deaths involving bacterial pathogens were most commonly associated with these deaths. In addition the most common risk factors in infants were exposure to tobacco smoke and co-sleeping. In adults the most common risk factors were co-morbid conditions and illnesses. This information aids in a better understanding of these deaths and highlights the need for more research in this field, particularly in developing countries.

RESUMEN

The objective of the present study was to identify risk factors among epidemiological factors and meteorological conditions in connection with fatal pulmonary embolism. Information was collected from forensic autopsy records in sudden unexpected death cases where pulmonary embolism was the exact cause of death between 2001 and 2010 in Budapest. Meteorological parameters were detected during the investigated period. Gender, age, manner of death, cause of death, place of death, post-mortem pathomorphological changes and daily meteorological conditions (i.e. daily mean temperature and atmospheric pressure) were examined. We detected that the number of registered pulmonary embolism (No 467, 211 male) follows power law in time regardless of the manner of death. We first described that the number of registered fatal pulmonary embolism up to the nth day can be expressed as Y(n) = α ⋅ n (ß) where Y denotes the number of fatal pulmonary embolisms up to the nth day and α > 0 and ß > 1 are model parameters. We found that there is a definite link between the cold temperature and the increasing incidence of fatal pulmonary embolism. Cold temperature and the change of air pressure appear to be predisposing factors for fatal pulmonary embolism. Meteorological parameters should have provided additional information about the predisposing factors of thromboembolism.

RESUMEN

Drowning is classified as the 3rd leading cause of accidental deaths worldwide and is deemed to be a preventable cause of death. Bodies retrieved from a water medium pose several challenges to the forensic pathologist with the diagnosis of drowning being primarily one of exclusion. The aim of this study was to do a retrospective descriptive case audit of bodies retrieved from water and immersion related deaths, which were investigated at the Pretoria Medico-Legal Laboratory (PMLL) over a 10 year period (January 2002 through December 2011). A total of 346 cases were identified for inclusion into this study. In 6% (20) of these cases, the death was not related to drowning; in 14% (48) no clear cause of death could be ascertained and in 278 cases (80%) the cause of death was considered to have been due to drowning. Infants (under 1 year, of age) constituted 41 (15%) of the cases; toddlers (aged 1-2 years) comprised 52 (19%) cases; children (aged 2-13 years) 49 (18%) cases; adolescents (aged 13-18 years) comprised 10 (3%) cases; adults (above 18, years) made up 126 (45%) of the cases. The majority of the drownings, occurred in swimming pools [125 cases (38%)]. In infants 23 (56%) of, drownings occurred in swimming pools followed by buckets [7 cases (17%)]. Sixty-nine per cent of toddler drownings (36 cases) occurred in swimming, pools. In the adult population, 40 (32%) of cases occurred in pools and 35 cases (28%) in rivers. Positive blood alcohol results were recorded in 48, (42%) out of 113 cases where the test was requested, 40 (35%) of these, cases higher than 0.05 g per 100 ml. This study suggests that many drowning deaths in Pretoria may be preventable by introducing greater public awareness of the risks and instituting relatively simple, protective measures.

RESUMEN

There is a dearth of literature on the extent of fetal or newborn abandonment or "dumping" and the medico-legal investigation procedures these cases require. This is despite the fact that these occurrences are a worldwide phenomenon and by definition involve criminal law concerns such as illegal abortion, concealment of birth, murder, or neonaticide, depending on the country concerned. This article contributes to current literature in both respects and provides a retrospective case audit for the period 2004-2008 pertaining to all abandoned newborns and fetuses admitted to the Pretoria Medico-Legal Laboratory (PMLL) in South Africa. Demographic details, scope, and nature of the medico-legal investigation as well as formulation of cause of death were recorded. A total of 289 cases were identified for inclusion in this study, 57% of which were considered to have been non-viable fetuses, while 45 of the viable fetuses were deemed to have been stillborn. These instances involve the crimes of concealment of birth and at times illegal abortion, yet prosecution of these cases are relatively unheard of. Signs of live birth were identified in 38 of the cases in the study. Of these infants, 9 were deemed to have died from injuries they have sustained, and in a further 9 cases, no anatomical cause of death could be identified. Homicidal cases should be brought in cases where death ensued as a result of abandonment; however, it is not known how many cases were prosecuted. A comparatively large number of cases were found to have been admitted to the Pretoria Medico-Legal Laboratory. This is alarming because South African abortion laws are liberal and services are free at point of access in the public health care sector. A substantial percentage of cases of abandoned infants were found to have shown signs of life after birth implying a homicidal manner of death or death by abandonment, but it seems these cases are merely shelved.

RESUMEN

La medicina legal es la especialidad médica que reúne todos los conocimientos de la medicina que son útiles a la administración de justicia, cumpliendo una función vital, al facilitar el intercambio de conocimientos entre las ciencias médicas y las ciencias jurídicas. La exigencia científica requerida en la realización de peritajes médico legales constituye un factor determinante para una adecuada administración de justicia. Cuando la Autoridad Judicial solicita un peritaje médico legal, debe entenderse como la solicitud de una investigación de carácter científico en la cual, el especialista en medicina legal, está en la obligación de cumplir a cabalidad como científico que es, basando su investigación en la aplicación del método científico. En la presente revisión se analiza la importancia de la aplicación del método científico en la elaboración de peritajes médico legales.

The Legal Medicine is the medical specialty that reunites all medical knowledge useful to justice administration, performing a vital role as facilitator of the knowledge exchange between medical science and legal science. The scientific management required to perform a medico-legal expertise is a determinant factor for the adequate justice administration. When the Judicial Authority requests a medico-legal expertise, it should be understood as a request for a scientific investigation in which the specialist in Legal Medicine is obliged to completely fulfilled this requirement as a scientist, basing his investigation in the application of the scientific method. In this review, it is analized the importance of the application of the scientific method in the elaboration of a medico legal expertise.

RESUMEN

The study compared the prevalence of common suicide risk factors between poisoning deaths classified as injuries of undetermined intent or suicides among women. Data were derived from the 2003-10 National Violent Death Reporting System. Multiple logistic regression assessed the factors associated with 799 undetermined deaths (relative to 3,233 suicides). Female decedents with lower education, a substance use problem, and a health problem were more likely to be classified as undetermined death. Older women, those with an intimate partner problem, financial problem, depressed mood, mental health problem, attempted suicide, and disclosed intent to die were less likely to be classified as undetermined death. The present study raises the possibility that many (perhaps most) undetermined female poisoning deaths are suicides.

RESUMEN

Assessment of individuals with injuries that may have been caused by intentional self-harm is part of routine work of forensic physicians. We present a case of deliberate self-harm of a 19 years old woman who claimed she had been cut by her partner during a quarrel while her partner claimed that she had injured herself. No forensic examination was performed. The case was first reviewed several months after the incident by experts giving consultations for the defense (the authors) by that time the only documentation of injury available were scant medical records and photos of very low quality. This case shows the importance of recognizing self-inflicted injuries even when only scant documentation is available, by comparing the injuries described to the different accounts of the incident as described by the complainant and defendant. Also the importance of availability of access of defense lawyers to forensic medical consultations is stressed.

RESUMEN

In forensics, the nature of collected evidence makes analysis in many disciplines complex. Each type of trace evidence requires a unique systematic approach, and even though these approaches are significantly based on the size and morphology of the evidence being examined. In 1999, the Council of Europe Committee of Ministers adopted the Recommendation No. R (99)3 on the harmonization of medico-legal autopsies. This document promoted the adoption of internationally recognized and standardized protocols for forensic autopsies. Nevertheless, the interdisciplinary philosophy still needs integration of information from various investigative sources. An orientated and correct examination of the oral cavity requires specific knowledge of its anatomy and physiopathology, and of the procedures most adapted for its study, and thus the participation of a qualified odontologist is advisable. On the basis that there is not a current protocol that establishes the participation of the dentist during all medico-legal autopsies, we present a review based on that significant document, including reports and personal findings of oral injury patterns. Finally, a new paradigm on the participation of the forensic dentist in the medico-legal investigation of death is discussed.

En ciencias forenses, la naturaleza de la evidencia recolectada deviene en análisis específicos realizados por muchas disciplinas complejas. Cada tipo de rastro requiere una aproximación única y sistemática, significativamente basada en el tamaño y la morfología de esa potencial evidencia. En 1999, el Consejo Europeo de Ministros adoptó la Recomendación No. R (99)3 para la armonización metodológica de las autopsias medicolegales. Este documento, promovió la adopción de protocolos estandarizados para las autopsias forenses de reconocimiento internacional. Sin embargo, la filosofía interdisciplinaria aún necesita integración de la información desde varias fuentes de investigación. Un examen orientado y correcto de la cavidad oral necesita de conocimientos específicos tanto de su anatomía y fisiopatología, de los procedimientos mejor desarrollados para su estudio, y de la participación de un odontólogo calificado para realizar este análisis. Sobre la base de que no existe un protocolo vigente que establezca la participación del odontólogo en todas las autopsias medicolegales, se presenta una revisión sobre este importante documento, incluyendo reportes y observaciones personales de algunos patrones de lesiones orales. Se discute además un nuevo paradigma respecto de la participación del odontólogo forense en la investigación médicolegal de la muerte.
