A saliva pode ser utilizada como fonte eficiente de DNA para tecnicas de identificacao humana, as quais sao aceitas como prova legal, sendo o parecer do profissional superlativo para a formulacao da sentenca. Esse material pode ser coletado de maneira indolor e nao-invasiva e utilizado mesmo quando armazenado em diferentes condicoes. Este trabalho objetiva avaliar a qualidade do DNA obtido de saliva humana armazenada e sua aplicabilidade da identificacao de pessoas. Foram analisadas amostras salivares de n=100 sujeitos da pesquisa, coletadas nas formas de saliva in natura e saliva coletada de swab. A saliva foi armazenada a -20ºC. Apos 7 dias, realizou-se a primeira etapa, quando o DNA foi extraido das 200 amostras de saliva utilizando-se a resina InstaGene (Bio-Rad Laboratories, Inc., Hercules, CA, USA) e, posteriormente, submetido a PCR e a eletroforese. Apos 180 dias de armazenamento da saliva, repetiu-se a mesma tecnica da primeira fase, porem em apenas 20 amostras, selecionadas aleatoriamente do total de 100 amostras de saliva coletadas por swab bucal. Os resultados da primeira etapa indicaram que o DNA foi extraido com sucesso em 96% das reacoes realizadas para as 200 amostras de saliva, fato observado tambem quando se analisou as amostras em separado, de saliva in natura (94%) e saliva advinda do swab (98%). Alem disso, nao houve diferencas estatisticamente significantes na extracao do DNA entre as duas formas de coleta de saliva utilizadas. Na segunda fase, foi possivel a deteccao do gene alvo nas 20 amostras analisadas (100%). Posteriormente, objetivando-se aprofundar a analise do DNA salivar de maneira mais proxima ao padrao exigido em um processo de identificacao, o gene SIX3-2 foi testado nas amostras e tambem foi feita a digestao do produto da PCR com a enzima de restricao MbO1 para avaliar polimorfismo do gene ADRA-2. Os resultados mostraram que a quantidade e a qualidade do DNA advindo de saliva do swab bucal, bem como as tecnicas empregadas estao adequadas a analise forense do DNA. Portanto, a saliva humana e bastante util como fonte de DNA e pode ser armazenada, em temperatura e condicoes ideais, para analise posterior. / The saliva can be used as efficient DNA source for human identification techniques in which they are accepted as forensic proof, being the superlative professionals opinion for the sentence formulation. This material can be collected in a painless and noninvasive way and it is used even when stored in different conditions. This paper aims at evaluating DNA quality obtained from stored human saliva and its applicability in people identification. Saliva samples from n=100 research subjects were analyzed. They were collected in two ways: in natura and swab. The saliva was stored at the temperature of -20°C. After 7 days, the first phase was performed, when the DNA was extracted from the 200 saliva samples using the InstaGene resin (Bio-Rad Laboratories, Inc., Hercules, CA, USA) and, subsequently, submitted to PCR and electrophoresis. After 180 days of the saliva storage, the same technique used in the first phase was repeated; however, in only 20 samples, selected at random from the total of 100 ones collected from mouth swab. The results of the first phase indicated that the DNA was successfully extracted in 96% of the reactions performed for the 200 saliva samples. This fact was also observed when the separate saliva samples in natura (94%) and swab (98%) were analyzed. In addition, there were no statistically significant differences in the extraction of the DNA between the two ways used for collecting saliva. In the second phase, the target gene detection was possible in the 20 samples analyzed (100%). Subsequently, the SIX3-2 gene was tested in the samples with the objective of deepening the salivary DNA analysis as close as the standard required in an identification process. Also, the digestion of the PCR product with the enzyme of MbO1 restriction was performed to evaluate the polymorphism of the ADRA- 2 gene. The results showed that the DNA quantity and quality from the mouth swab saliva, as well as the techniques applied are suitable for the forensic analysis of DNA. Therefore, the human saliva is very useful as DNA source and can be stored in ideal temperature and conditions for further analysis.

Este ensaio inicia-se com um sucinto painel a respeito de uma pesquisa bibliográfica sobre Medicina Legal que começa com Ambroise Paré em 1532 e chega ao ano de 2008; pesquisa esta que muito nos ajudou no planejamento desta Tese. É preciso que se diga que o conceito de Medicina Legal só aparece em 1621 com Paolo Zacchia (Quaestiones Medico Legales...). Nosso objetivo neste trabalho envolve diferentes aspectos teóricos dessa ciência. O primeiro é o de demonstrar que a Medicina Legal pode ser a ciência de uma classe no sentido da Lógica e que ela não seria, portanto, a exemplo da Medicina Clínica, uma ciência do indivíduo, como diz Gilles Granger em sua obra sobre Epistemologia já tornada célebre. O segundo aspecto teórico seria o de propor a Medicina Legal como uma ciência do freqüente aristotélico (hòs epì tò polú ws epi to polu - termo cunhado pelo helenista Porchat Pereira, enquanto conceito filosófico) graças ao qual situamos nossa ciência entre o acidental e o necessário e universal do pensamento lógico-matemático. Em terceiro lugar discorreremos sobre o fato de que os laudos médico-legais estão normalmente restritos a constatação empírica e, então, iremos demonstrar a também indispensável consideração das condições a priori da possibilidade de se estabelecer o visum et repertum, ou seja, a consideração do papel do encéfalo na leitura da experiência possível ao ser humano, numa linguagem atual. No que diz respeito à prática, realizamos uma pesquisa na qual analisamos 996 laudos médico-legais, no Brasil, cujos problemas nos remeteram à questão do Método. Sobre o Método, consideramos as teorias de Aristóteles, Descartes, Kant, Popper, Piaget e Granger, deixando de lado os grandes empiristas como Francis Bacon, David Hume, Stuart Mill, na medida em que suas teorias, devido às crenças embutidas no próprio Empirismo, não há lugar para o cérebro como condição primeira de qualquer tipo de leitura da experiência no mundo sensível. Ora, muitos biólogos, inclusive no Brasil, a partir do Prêmio Nobel em Fisiologia ou Medicina, Konrad Lorenz, consideram que o a priori kantiano pode ser interpretado hoje, como o aspecto endógeno, orgânico, da possibilidade humana de conhecer o mundo (o encéfalo) necessário a toda e qualquer leitura da experiência vivida, sobretudo quando houver a necessidade de explicá-la e reportá-la a terceiros. No caso da Medicina Legal, reportá-la à Justiça, com muitíssimas implicações psico-sociais. Nós proporemos então, à Medicina Legal, um Método Dialético, procurando demonstrar suas vantagens teóricas e práticas. / This essay begins with an overview of a bibliographic research on Forensic Medicine, from its early onset with Ambroise Paré, in 1532, up to the present. This research played an important role on the planning of this thesis (it is important to emphasize that the proper concept of Forensic Medicine, however, appears only in 1621 with Paolo Zacchia,-Quaestiones-Medico-Legales...). Our purpose in this work includes many theoretical aspects of this science, first of all, to show that Forensic Medicine should be considered a science of a class in the sense of Logic, instead of, as in Clinical Medicine, \"a science of the individual\", as stated by Gilles Granger in his already classical work on epistemology. The second theoretical objective will be to propose Forensic Medicine as a science of the \"Aristotelian frequent (hòs epì tò polú term coined by the Hellenist Porchat Pereira as a philosophical concept), through which such science should find its place between the realm of the mere accidental, and that of the necessary and universal, proper to the logic-mathematical reasoning. Thirdly, we also address the problem that the forensic reports are usually limited to empirical observations, and, then, we will also demonstrate the necessity to take into account a priori conditions of the possibility of the making of Visum et repertum, that means, we aim to consider the role of the brain in the framing of the human beings accessible experience, through a contemporary approach. On the empirical side, we conducted an extensive research, analyzing 996 Brazilian forensic reports, whose problems led us to questioning the generally used method. On the method, we discussed the theories of Aristotle, Descartes, Kant, Popper, Piaget and Granger, leaving aside the great empiricists such as Francis Bacon, David Hume, Stuart Mill, as in their theories, due to the embedded beliefs of empiricism, there is no room for the brain as the first condition of the possibility of any kind of sensory experience of the world. However, many biologists worldwide (Brazil included), since the work of Konrad Lorenz (Nobel Prize, Physiology or Medicine, 1973) has begun to circulate amid the scientific community, moved to consider that the Kantian a priori can be interpreted as the endogenous aspect (organic) of the human ability to apprehend the world, necessary to any construction of actual experience, especially when there is an intent to explain and report it to others. In the case of Forensic Medicine, it means reporting the findings to the Judicial System, which entails many psycho-social effects. Finally, we propose to Forensic Medicine a dialectical method, aiming to demonstrate its theoretical and practical advantages.

A despeito das leis que visam garantir a defesa dos direitos das crianças e adolescentes, diversas formas de violência continuam a acometer diariamente estes seres em formação, produzindo pessoas psicologicamente desajustadas e propensas à continuidade do comportamento violento em suas relações. O presente trabalho analisa o perfil epidemiolágico das crianças e adolescentes vítimas de violência familiar na Região Metropolitana da Grande Vitória, nos anos de 2002 e 2003, examinadas no Departamento Médico Legal da citada região. Foi realizado um estudo retrospectivo dos laudos de Exame de Lesões Corporais dos arquivos daquele Departamento, sendo detectados 895 casos de crianças e adolescentes vítimas de agressões não-fatais impostas pelos seus familiares. Ao contrário de outros trabalhos, a maior parte das vítimas era do sexo feminino (567 - 63,35%), contra 328 (36,64%) do sexo masculino. Na maioria dos casos (482 - 53,85%) os principais agressores foram os pais biológicos, seguidos pelo padrasto (111 - 12,40%). A maior incidência de agressões se deu nos fins de semana e aconteceram por meio de trauma direto, com as próprias mãos, mas o uso de cinto e outros objetos caseiros foi relatado em 129 casos (14,41%). Em 89 casos (9,94%) as vítimas não apresentavam nenhuma lesão corporal visível. As lesões mais freqüentes eram equimoses (479 - 59,42%), escoriações (400 - 49,62%) e hematomas (184 - 22,82%). As regiões corporais mais atingidas foram os membros superiores (390 - 25,74%), a cabeça (351 - 23,30%), os membros inferiores (269 17,75%) e a face posterior do tórax (180 - 11 ,88%). Na face, as regiões mais atingidas foram as orbitárias (79 -15,22%), a frontal (74 - 14,25%) e a oral (69 - 13,29%). Em 54 circunstâncias houve várias vítimas da mesma família, totalizando 117 crianças ou adolescentes agredidos, em sua maioria, pelos pais biológicos. Foram observados 8 casos (14,81%) em que as vítimas eram irmãos gêmeos. De acordo com os critérios do Código Penal Brasileiro, a maior parte das crianças e adolescentes deste estudo sofreu um dano físico classificado como Lesão Corporal de Natureza Leve, uma vez que não apresentaram um dano maior para a integridade física ou funcional / Abstract: Family Violence represents one of the cruelest faces of violence, because it affects defenseless people, women and children, mostly in their own homes, where protection and well-being are expected. Despite the laws focusing on the rights for children and teenagers, several forms of violence continue to psychologically affect children in such age group, promoting violent behavior in their relationship. The present work analyzed the epidemiological profile of children and teenagers victims of family violence in the Metropolitan Region of Grande Vitoria, between 2002 and 2003. Individuais were examined at the Legal Medicine Department in that region. A retrospective study of forensic examination records of that Department was conducted. A total of 895 cases of children and teenagers victims of non-Iethal aggressions by their family members were detected. However, previous studies verified that most of the victims were female (567 female - 63.35% and 328 male - 36.64%). Besides, the highest incidence of cases was verified for teenagers, aged 15-18 years. There was no significant difference between teenagers (450 - 50.27%) and children (445 - 49.72%). In most cases (482 53.85%), the main aggressors were the biological parents, followed by stepfather (111 - 12.40%). The highest incidence of aggressions occurred on weekends by means of direct trauma, with bare hands; the use of a belt and other household objects was related in 129 cases (14.41%). In 89 cases (9.94%), the victims presented no corporal lesions. The most frequent lesions were bruise (479 59.42%), scratch (400 - 49.62%) and hematoma (184 -22.82%). The most affected body regions were the upper limbs (390 - 25.74%), head (351 - 23.30%), lower limbs (269 - 17.75%), and posterior thorax (180 - 11.88%); as for the face, the orbits (79 - 15.22%), the forehead (74 -14.25%) and the mouth (69 - 13.29%) were the most affected regions. In 54 cases, there were several victims of the same family, totaling 117 children or teenagers, most of whom were violently punished by their parents. In 8 cases (14.81%), the victims were twin brothers. According to criteria described in the Brazilian Penal Code, most children and teenagers in this study suffered damage classified as Minor Corporal Lesion, since their physical or functional integrity was not affected. / Mestrado / Mestre em Odontologia Legal e Deontologia

This thesis examines the practice of forensic medicine in Scotland in the period 1914 to 1939. This was a time of significant dynamism for the discipline, in which it enjoyed a high public profile and played an important role in the investigation of crime. The project focuses in particular on medico-legal practice at an elite level, based in specialist departments in the universities of Edinburgh and Glasgow. As well as producing a significant amount of research and textbook material, and thus constituting authorities within the discipline, representatives of these institutions gave expert evidence in a number of high-profile trials. Thus, an examination of their work can show how medico-legal knowledge was constructed, presented and challenged. To this end, four main areas of forensic medical practice are analysed, including the post-mortem examination, the laboratory analysis of trace evidence, the investigation of shootings and the use of photography. The development of the techniques contained within these categories is charted, as is the range of situations to which they were applied and the various ways in which their use was challenged in court by hostile legal counsel. Sources including textbooks and journal articles, medical case reports, photograph albums and trial transcripts are used. A fifth section explores an area of the public face of the discipline, specifically the popular output of two of its most famous practitioners, Sydney Smith and John Glaister Jr. Both produced memoirs and newspaper serials after retirement. These are used to explore the ways they reflected on their careers and spun their legacies, portraying themselves as impartial servants of science and justice. The thesis argues that the place of forensic medicine in wider institutional, investigative and geographical networks was central to its existence. The discipline collaborated extensively, both with representatives of other areas of the medical profession and with external authorities, professions and trades. Means of communication, such as written reports and samples taken at autopsy, allowed experts in the universities to lend their expertise to the non-specialists in peripheries by providing expert opinions based on materials sent to them. The scrutiny of post-mortem reports produced by peripheral generalists allowed medico-legists’ expertise to be spread over a wide geographical area. The thesis also reflects on the ways in which medico-legists guarded against error. Techniques derived from other areas of medicine and science were not adopted for use in court until their reliability could be demonstrated satisfactorily, and controls and standards were built in to procedures.

Le rapport d’expertise du médecin légiste a souvent un rôle déterminant dans de nombreux procès criminels pour condamner ou relaxer un mis en cause. En révélant des faits utiles à l’enquête, le médecin légiste a le devoir d’être neutre, d’utiliser les données actuelles de la science et de rechercher la vérité de ce qui s’est passé. Mais la position classique de neutralité axiologique est-elle pertinente? Peut-on évacuer les valeurs de l’expertise ? La vérité est-elle accessible ? Qu’est-ce que la science en médecine légale ? Le médecin légiste n’utiliserait-il pas d’autres outils pour arriver à ses conclusions ? Pour répondre à ces questions, ce travail se propose d’étudier le rapport entre faits et valeurs au sein de l’expertise médico-judiciaire ainsi que d’examiner comment s’élaborent les conclusions du médecin légiste et la manière dont il les exprime. / The expert report composed by a forensic pathologist often plays a key role in many criminal trials in order to either free or convict the defendant. By unearthing useful facts for the inquiry, the forensic pathologist has a duty to be neutral, use up-to-date scientific knowledge and data and to search for the truth in underlying events. But is the usual position of axiological neutrality relevant? Can values be evacuated from the expertise? Can the truth be achieved? What is actually science in the field of forensics? Is the forensic pathologist not using other tools to reach a conclusion? To address these issues, this work proposes to investigate the relationship between facts and values in the field of forensic expertise, as well as to examine the way the forensic scientists draw conclusions and in turn how these are stated.

The benefits of the computed tomography in the forensic medicine Radiological imaging methods represent one of the complementary examination methods supplementing conventional autopsy in addition to histological, toxicological, biochemical, microbiological, and serological examination in forensic medicine. The basic and commonly available radiological imaging method in forensic practice is X-ray imaging. With the development of modern radiological imaging methods (especially computed tomography and nuclear magnetic resonance), these modern methods have been gradually applied to the field of forensic medicine. The rapid development of radiological imaging methods in recent years (especially computed tomography and nuclear magnetic resonance) has caused the gradual application of these modern methods in the field of forensic medicine. Post mortem CT (pmCT) examination is now a common part of forensic medicine in the most developed world countries (Switzerland, Denmark, Australia, Japan, Germany, Italy, France and others) and since 2015 this examination has been available at two departments of forensic medicine in the Czech Republic. The primary aim of the study was to evaluate the benefits of pmCT examination in routine forensic practice in three comprehensive groups of individuals who died as a result of...

<p>Određivanje koncentracije etanola u telesnim tečnostima, pre svega u krvi, neophodan je uslov da bi se ustanovio uticaj alkoholemije na psihomotorne sposobnosti. Poznavanje stabilnosti lekova, droga i metabolita u biolo&scaron;kim uzorcima je od ključne važnosti kada se ukaže potreba za ponovljenom analizom i evaluacijom rezultata u sudskom postupku. Osnovni ciljevi ovog rada su da se uz pomoć HS-GC metode (hedspejs gasna hromatografija) ustanovi da li postoji statistički značajna promena koncentracije etanola u uzorcima krvi dobijenih od živih osoba i u biolo&scaron;kim uzorcima uzorcima sa autopsijskog materijala. Na osnovu rezultata potrebno je bilo utvrditi u kojem tipu uzorka uzetog sa le&scaron;nog materijala postoji najmanja promena koncentracije tokom perioda čuvanja uzorka. Istraživanje je bilo otvoreno, randomizirano i prospektivnog tipa. Biolo&scaron;ki uzorci krvi krvi živih osoba i le&scaron;nog materijala (krv, mokraća i staklasto telo) uzimani su metodom slučajnog izbora, u rasponu alkoholemije od 0,1 mg/ml do 5 mg/ml. Nakon inicijalne dvostruke analize, jedan biolo&scaron;ki uzorak čuvan je u trajanju od 180 dana, dok je drugi otvaran i analiziran nakon 60, 120 i 180 dana. Ukupan broj analiza alkoholemije u krvi živih osoba iznosio je 500. Ukupan broj analiza koncentracije etanola u krvi, mokraći i staklastom telu sa le&scaron;eva iznosio je 360. Etanol je u uzorcima krvi živih osoba, kao i u biolo&scaron;kim uzorcima sa autopsijskog materijala određivan metodom HS GC. Tokom čuvanja biolo&scaron;kih uzoraka u periodu od &scaron;est meseci ustanovljeno je da je do&scaron;lo do značajnog smanjenja koncentracije etanola u svim analiziranim uzorcima, nezavisno od njegovog porekla. Promena koncentracije etanola tokom čuvanja u zavisnosti je od tkivne vrste uzorka, inicijalne alkoholemije, dužine čuvanja, integriteta vijala i čepova, temperature, odnosa tečne i gasne faze, prisustva konzervansa i potencijalnog intermitentnog otvaranja radi analiza.</p> / <p>Determination of ethanol concentration in body fluids, especially blood, is a necessary objective to establish the influence of alcohol on psychomotor skills. Knowing the stability of medicines, drugs and metabolites in biological samples is of crucial importance when there is a need for repeated analysis and result evaluation in court. The main objectives of this work were to determine whether there was a statistically significant change in ethanol concentration in blood samples obtained from living subjects and from autopsy material, by using HS-GC method (headspace gas chromatography). Based on the results it was necessary to determine which type of sample collected from autopsy showed the lowest change in concentration during the storage period. The study was open, randomized and prospective. Biological samples of living person&#39;s blood and autopsy biological samples (blood, urine and the vitreous humor) were taken at random, in the level range between 0.1 mg/ml and 5 mg/ml. After an initial duplicate analysis, one biological sample was stored for a period of 180 days, while the other was opened and analyzed after 60, 120 and 180 days. Total number of analysis of living person&#39;s blood samples was 500. The total number of analysis of autopsy biological samples was 360. All concentrations were determined by HS-GC method. During the storage, results showed that there has been a significant decrease in the concentration of ethanol in all of the analyzed samples, regardless of its origin. The level of this change was dependent on the type of tissue sample, initial alcohol concentration, duration of storage, integrity of the vials and stoppers, temperature, ratio of liquid and gas phases, presence of preservatives and intermittent opening for analysis.</p>

Etablir le diagnostic différentiel entre des fractures réalisées sur os frais de celles produites sur os sec permet, quelle que soit la période chronologique considérée, une approche interprétative relative à l’attitude comportementale humaine qu’ils s’agissent des relations au sein d’un groupe ou face à une autre population, ainsi que les gestes réservés aux morts. Ainsi peuvent être envisagés le cannibalisme, des comportements de violence, ou des pratiques funéraires originales. Si certaines méthodes analytiques existaient pour le squelette infracrânien, aucun référentiel permettant de différentier les fractures sur os frais (intentionnelles ou non) des cassures sur os secs n’est actuellement disponible pour le squelette crânien. Notre objectif de recherche s’est donc concentré sur un essai de détermination des critères statistiquement valides de distinction du moment de fracturation sur os fossiles. Une partie importante de ce travail est consacrée aux études expérimentales menées pour tenter de distinguer une différence de comportement mécanique entre une fracture réalisée sur os frais de celle réalisée sur os sec (essais mécaniques, rugosimétrie confocale, microtomographie ou numérisation des pièces osseuses). Puis, les critères de la médecine légale sont discutés à partir d’échantillons osseux provenant de séries archéologiques différentes d’un point de vue chronologique et géographique et relevant de problématiques différentes. Il ressort de ce travail que très peu de critères pris individuellement sont suffisamment pertinents pour différencier fracturation sur os frais et fracturation sur os sec (décollement de la lame corticale). Ils doivent toujours être discutés à l’échelle d’une série archéologique et non sur un échantillon isolé, seul ou sorti de son contexte. Dans le meilleur des cas, ils nous permettent de proposer des hypothèses (cannibalisme, pression des sédiments…) qui devront être corroborées en fonction du contexte archéologique et anthropologique par une analyse interdisciplinaire. / Establishing a differential diagnosis between fresh bone fractures and dry bone fractures allows, whatever the chronological period considered, an interpretative approach relating to the human behaviours within a group or another population, as well as the deaths gestures. Thus, cannibalism, violent behaviours, or original funerary practices can be considered. If some analytical methods existed for the infracranial skeleton, no references allowing for the differentiation between fresh bone fractures (intentional or not) and dry bone breaks were available for the cranial skeleton. Thus, our research objective concentrated on a determination trial of statistically valid criteria that distinguished the fracturing moment on fossil bones. An important part of our work concerned experimental studies undertaken to distinguish a mechanical behavioural difference between fresh bone fractures and dry bone fractures (mechanical tests, rugosimetry, microtomography, or bone pieces digitalization). Forensic medicine criteria was also discussed with osseous samples coming from different archeological series that were taken from chronological and geographical points of view and used to represent each different problem. It appears that there exist very few criteria taken individually that are sufficiently relevant to differentiate fracturing on fresh bone and fracturing on dry bone (delamination). They must always be discussed on an archeological series scale and not on an isolated sample, either alone or taken out of context. In the best of the cases, they enable us to propose assumptions (cannibalism, pressure of the sediments…) that will have to be corroborated according to the archaeological and anthropological context by an interdisciplinary analysis.
