O ensino da Medicina Legal na formação profissional da carreira jurídica

A introdução do ensino médico-legal nos currículos de Direito, já assegura longa data e teve sua proposta relatada por Rui Barbosa e aprovada na Câmara dos Deputados, após o que o Governo brasileiro determinou a criação da cátedra de Medicina Legal nas Faculdades de Direito do país a partir de 1891. Ao longo de muitos anos foi disciplina obrigatória nos cursos de Direito transparecendo a importância da matéria na formação dos profissionais, mormente aqueles que militam na esfera criminal, mas também aplicável a, praticamente, todas as especialidades da área jurídica. A despeito da evolução das ciências forenses, que introduziram no século XXI novos horizontes da sua aplicação no contexto jurídico, ressalto ainda a própria cobrança da matéria nos concursos, para aqueles que almejam a carreira Policial. No entanto, independente da indiscutível importância da matéria, na formação acadêmica do profissional de direito, o Ministério da Educação decidiu estabelecer a Medicina Legal como disciplina optativa nos cursos de Direito. Essa medida veio ao de encontro dos interesses sociais, pois a sociedade, na busca de seus direitos, requer profissionais bem formados, com conhecimento compatível com a evolução científica. Ensinar Medicina Legal é uma árdua tarefa, pois há necessidade de valorizar mais a atividade docente e proporcionar meios para que esse ensino seja amplamente desenvolvido na formação da carreira jurídica. No presente trabalho são expostas as argumentações técnicas e pedagógicas para a manutenção de disciplina como obrigatória nos Cursos de graduação em Direito, visando, com isso, uma formação acadêmica mais completa, que corresponda a sua importante aplicação nas diversas áreas do Direito, bem como sua implantação como disciplina obrigatória nos exames de ordem da OAB.

Sudden cardiac death in forensic medicine - Swiss recommendations for a multidisciplinary approach.

Sudden cardiac death (SCD) is by definition unexpected and cardiac in nature. The investigation is almost invariably performed by a forensic pathologist. Under these circumstances the role of the forensic pathologist is twofold: (1.) to determine rapidly and efficiently the cause and manner of death and (2.) to initiate a multidisciplinary process in order to prevent further deaths in existing family members. If the death is determined to be due to "natural" causes the district attorney in charge often refuses further examinations. However, additional examinations, i.e. extensive histopathological investigations and/or molecular genetic analyses, are necessary in many cases to clarify the cause of death. The Swiss Society of Legal Medicine created a multidisciplinary working group together with clinical and molecular geneticists and cardiologists in the hope of harmonising the approach to investigate SCD. The aim of this paper is to close the gap between the Swiss recommendations for routine forensic post-mortem cardiac examination and clinical recommendations for genetic testing of inherited cardiac diseases; this is in order to optimise the diagnostic procedures and preventive measures for living family members. The key points of the recommendations are (1.) the forensic autopsy procedure for all SCD victims under 40 years of age, (2.) the collection and storage of adequate samples for genetic testing, (3.) communication with the families, and (4.) a multidisciplinary approach including cardiogenetic counselling.

One small scan for radiology, one giant leap for forensic medicine - Post-mortem imaging replaces forensic autopsy in a case of traumatic aortic laceration

The questions of cause and manner of death are the most pressing ones in any forensic investigation. Traditionally, autopsy is the means to provide answers to these questions and despite the increasing use of CT and MR in the post-mortem setting, imaging has usually been an adjunct to forensic autopsy. Here we describe a case where post-mortem CT and MR were performed instead of autopsy, at the request of the responsible public prosecutor. The forensic conclusions derived from imaging, including cause and manner of death were accepted by the legal authorities, thereby setting precedence for future cases. This case represents a landmark in forensic medicine and is another step toward the full realization of minimally invasive forensic autopsy.

Virtopsy - the concept of a centralized database in forensic medicine for analysis and comparison of radiological and autopsy data

Recent developments in clinical radiology have resulted in additional developments in the field of forensic radiology. After implementation of cross-sectional radiology and optical surface documentation in forensic medicine, difficulties in the validation and analysis of the acquired data was experienced. To address this problem and for the comparison of autopsy and radiological data a centralized database with internet technology for forensic cases was created. The main goals of the database are (1) creation of a digital and standardized documentation tool for forensic-radiological and pathological findings; (2) establishing a basis for validation of forensic cross-sectional radiology as a non-invasive examination method in forensic medicine that means comparing and evaluating the radiological and autopsy data and analyzing the accuracy of such data; and (3) providing a conduit for continuing research and education in forensic medicine. Considering the infrequent availability of CT or MRI for forensic institutions and the heterogeneous nature of case material in forensic medicine an evaluation of benefits and limitations of cross-sectional imaging concerning certain forensic features by a single institution may be of limited value. A centralized database permitting international forensic and cross disciplinary collaborations may provide important support for forensic-radiological casework and research.

Multi-phase post-mortem CT angiography: development of a standardized protocol.

The objective of this work was to develop an easily applicable technique and a standardized protocol for high-quality post-mortem angiography. This protocol should (1) increase the radiological interpretation by decreasing artifacts due to the perfusion and by reaching a complete filling of the vascular system and (2) ease and standardize the execution of the examination. To this aim, 45 human corpses were investigated by post-mortem computed tomography (CT) angiography using different perfusion protocols, a modified heart-lung machine and a new contrast agent mixture, specifically developed for post-mortem investigations. The quality of the CT angiographies was evaluated radiologically by observing the filling of the vascular system and assessing the interpretability of the resulting images and by comparing radiological diagnoses to conventional autopsy conclusions. Post-mortem angiography yielded satisfactory results provided that the volumes of the injected contrast agent mixture were high enough to completely fill the vascular system. In order to avoid artifacts due to the post-mortem perfusion, a minimum of three angiographic phases and one native scan had to be performed. These findings were taken into account to develop a protocol for quality post-mortem CT angiography that minimizes the risk of radiological misinterpretation. The proposed protocol is easy applicable in a standardized way and yields high-quality radiologically interpretable visualization of the vascular system in post-mortem investigations.

Is the formula of Traub still up to date in antemortem blood glucose level estimation?

According to the hypothesis of Traub, also known as the 'formula of Traub', postmortem values of glucose and lactate found in the cerebrospinal fluid or vitreous humor are considered indicators of antemortem blood glucose levels. However, because the lactate concentration increases in the vitreous and cerebrospinal fluid after death, some authors postulated that using the sum value to estimate antemortem blood glucose levels could lead to an overestimation of the cases of glucose metabolic disorders with fatal outcomes, such as diabetic ketoacidosis. The aim of our study, performed on 470 consecutive forensic cases, was to ascertain the advantages of the sum value to estimate antemortem blood glucose concentrations and, consequently, to rule out fatal diabetic ketoacidosis as the cause of death. Other biochemical parameters, such as blood 3-beta-hydroxybutyrate, acetoacetate, acetone, glycated haemoglobin and urine glucose levels, were also determined. In addition, postmortem native CT scan, autopsy, histology, neuropathology and toxicology were performed to confirm diabetic ketoacidosis as the cause of death. According to our results, the sum value does not add any further information for the estimation of antemortem blood glucose concentration. The vitreous glucose concentration appears to be the most reliable marker to estimate antemortem hyperglycaemia and, along with the determination of other biochemical markers (such as blood acetone and 3-beta-hydroxybutyrate, urine glucose and glycated haemoglobin), to confirm diabetic ketoacidosis as the cause of death.

Ischemic heart disease in postmortem CT and CT angiography

Objective: Postmortem radiology had in recent years appeared in the field of forensic medicine and is now considered by some authors as a good replacement for conventional autopsy and by others as a complementary examination. Although postmortem CT radiological imaging is very useful in demonstrating traumatic lesions, its utility is still quite limited in the cardiovascular field. This limitation could be minimized by the introduction of postmortem angiography. At the University Center of Legal Medicine of Lausanne, CT scans and postmortem multiphase CTangiography are used in cases with a suspicion of ischemic heart disease.Method: The goal of this presentation is to demonstrate some correlations between postmortem CT, CTangiography and conventional autopsy examination in cases of ischemic heart disease.Results: We observed that the native CT scan can show only some pathological findings as cardiac tamponade and calcifications of coronary arteries. However, postmortem angiography allows a better visualization of coronary arteries and evaluation of stenosis and occlusion as well as better imaging of soft tissue.Conclusion: The interpretation of postmortem modern radiology is a new field for both forensic pathologists and radiologists who have to learn to read the postmortem modified images. The information obtained from both parties can help to further the understanding of CT and CT angiography in postmortem cases.

Exploration of implicit theories in the formation of expert opinion in portuguese criminal law

This dissertation examines different aspects involved in the formation of psychologists’ expert opinion in the Portuguese criminal justice system, more precisely, as this opinion is reflected in assessment reports. The present dissertation is comprised of three qualitative studies, the first sought to provide a general portrait of a sample of 106 forensic psychological reports as to their overall quality as measured in terms of relevance and coherence. Results show that the formal markers of quality are present in the sample analysed, a certain number of weaknesses have been observed, notably concerning the internal coherence of the reports as well as the relevance of the information reported on. The second study explored the opinions of 17 Portuguese judges and state prosecutors concerning the use they make of this type of forensic report. It appears that they consider these reports to be useful and very credible, specially so when they have been produced under the auspices of the National Institute of Legal Medicine and Forensic Sciences, which is the state forensic institution. Furthermore, it appears that judges and prosecutors were particularly interested in data that allowed for a personalised portrait of the assessee. The third study sought to better comprehend the conceptual bases on which psychologists construct their reports. To this end, an exploratory study was undertaken with a sample of key-actors; the analysis of their interviews shows that they define their judicial mandate as well as the basic concepts that are associated to this mandate in different ways. A theoretical framework provided by an implicit theories model was used to help understand these results.

Vers une autre temporalité de la "parthénos" : entre mythe, littérature et disciplines du corps

Cette thèse trace la généalogie culturelle de la jeune fille en Occident en ciblant les moments charnières de son devenir femme au sein de structures de savoir qui ont activement participé à forger cette figure hétéronormative. Mon objectif est de produire une analyse culturelle en forgeant une cartographie des adolescences au féminin. Afin de sortir de la temporalité téléologique de la virginité et de la défloration, j’emprunte un mot étranger, parthénos, qui fait appel à l’idée de la jeune fille, sans nécessairement se limiter à ses connotations conventionnelles. La première partie, intitulée « La virginité, une affaire de jeunes filles », laisse place à une analyse du concept de parthénos à partir d’une lecture au carrefour de la médecine, de la loi et du mythe. Une lecture du traité hippocratique De la maladie des jeunes filles dévoile comment la défloration et la grossesse deviennent une cure érotique, une discipline du corps, qui décide du passage de la jeune fille dans une temporalité utile à la Cité. Un déplacement paradigmatique s’opère au 19e siècle dans les écrits médico-légaux, parce que l’hymen, auparavant inexistant dans la doxa hippocratique, devient le signe matériel par excellence pour examiner le statut de virginité de la fille. L’analyse de ces traités (frères Beck, Ambroise Tardieu, Paulier et Hétet) révèle la configuration de pratiques et de discours d’infantilisation des victimes de viol, et le refus des médecins légistes de reconnaître qu’une femme mariée puisse être violée. À partir d’une lecture contemporaine des tragédies L’Orestie d’Eschyle et Antigone de Sophocle, je montre que les figures d’Antigone et d’Électre constituent des exemples et des symboles convaincants de ce destin funeste de la parthénos qui n’accède jamais au statut de femme mariée. À ces figures mortelles, se télescopent les figures d’Artémis et des Érinyes pour montrer le potentiel de régénération inhérent à la figure de la parthénos. La deuxième partie, qui porte le titre « Le liminaire. Repenser les devenirs de l’adolescence », engage une réflexion à la lisière du contexte contemporain des Girlhood Studies, de la psychanalyse sociale et des études féministes sur le corps et le sexe, pour faciliter le déploiement d’une cartographie plus contextualisée du concept de parthénos. Je montre ici les écueils et les effets du danger qu’engendre la rationalité économique (cf. Henry A. Giroux) pour les espaces de liberté et d’exploration propres à l’adolescence. Cette posture est appuyée sur une lecture des récentes études en psychanalyse sociale (Anne Bourgain, Olivier Douville et Edmond Ortigues). Il est ainsi question d’identifier ce qui marque le passage entre l’adolescence et l’âge adulte : la crainte de la disparition et le fantasme de la naissance de soi. La théorie de la volatilité corporelle qu’élabore Elizabeth Grosz à propos de la sexualité féminine, ainsi que les théories de Michel Foucault, reprises par Judith Butler, en ce qui concerne les disciplines du corps, répondent à mon objectif de sortir de l’écueil d’une temporalité téléologique pour saisir les effets et les ramifications du discours sur la matérialité du corps de la jeune fille, sur ce qui lui arrive lorsqu’elle ne correspond pas tout à fait à l’idéal de régulation. Enfin, la dernière partie, qui porte le titre « Temporalités de la parthénos en tant que sujet liminaire », est traversée par les modalités particulières de la parthénia qui semble désincarnée dans la littérature contemporaine. L’objectif est de prouver que la virginité est toujours un marqueur symbolique qui déploie le destin de la fille dans un horizon particulier, trop souvent celui de la disparition. En proposant un éventail de cinq textes littéraires que j’inscris au sein d’une posture généalogique, je souhaite voir dans la littérature contemporaine, une volonté, parfois aussi un échec, dans cette pensée de la parthénos en tant que sujet liminaire. Le récit Vu du ciel de Christine Angot montre que l’ascension vers le statut d’ange concerne seulement les victimes enfants. Le récit d’Angot met donc en lumière la distinction entre la vraie victime, toujours innocente et pré-pubère, et la fausse victime, l’adolescente. Contrairement à Vu du ciel, The Lovely Bones d’Alice Sebold met en scène la possibilité d’une communauté politique de filles qui sera en fait limitée par le refus du potentiel lesbien. La question du viol sera ici centrale et sera abordée à partir de l’insistance sur la voix de la narratrice Susan. La littérature devient un espace propice à la survie de la jeune fille, puisqu’elle admet la reprise de l’expérience de la première relation sexuelle. Si la communauté est convoquée dans The Lovely Bones, elle est associée à l’image de l’identité sororale dans le roman Virgin Suicides de Jeffrey Eugenides. La pathologie virale et la beauté virginale que construit le narrateur polyphonique et anonyme font exister le discours médical sur la maladie des vierges dans un contexte contemporain. Le récit médical rejoint alors le récit érotique puisque le narrateur devient médecin, détective et voyeur. À la différence de ces trois récits, Drames de princesses d’Elfriede Jelinek montre une parthénos, Blanche Neige, qui fait face à son agresseur pour s’inscrire dans une historicité discursive. Cette collision dialogique ranime le cycle tragique (celui d’une Antigone confrontant Créon) et traduit de nouveau le danger d’une superstructure sociétale composée d’images et de discours où la fille est construite comme un accessoire pour le plaisir éphémère de l’homme. À l’inverse de l’image de la vierge sacrée et désincarnée que proposent les récits d’Angot, de Sebold, d’Eugenides et de Jelinek, Virginie Despentes offre une autre réflexion dans Apocalypse bébé. Le personnage de Valentine est configuré comme une sœur des parthénoi qui préfère le suicide et la terreur à la domestication, faisant ainsi appel à une temporalité radicale et inachevable, celle de la fin de la jeune fille. Mon souhait est enfin de souligner la nécessité de penser au mérite autant épistémologique, intime que politique, d’explorer le temps des éclosions sexuelles de la fille par delà l’idée de la première relation sexuelle.

Muertes por sustancias químicas en el ámbito laboral municipio de Soacha 1993 - 2008

Este trabajo permite tener un acercamiento a la magnitud del problema que generan las sustancias químicas en los trabajadores de un municipio de Cundinamarca entre los años 1993-2008 basándose en los informes obtenidos de la unidad básica de la Dirección seccional Cundinamarca Regional Oriente del Instituto Nacional de Medicina Legal y Ciencias Forenses; hallando como principal causa de muerte la intoxicación por monóxido de carbono, en los trabajadores del sector informal. Genera además la inquietud de crear, un instrumento que permita un adecuado registro de estos eventos y a través de este, programas dirigidos a empleadores y trabajadores, que pueda concientizarlos de la exposición a la que se someten, ante un enemigo invisible como lo son las sustancias químicas y cuya consecuencia se observa claramente en la mortalidad de menores de edad que se encontraron durante la revisión de los informes

Prevalencia de anormalidades estructurales cardiacas en pacientes con enfermedad isquémica. Bogotá 2007 – 2009

Introducción: Las enfermedades cardiovasculares son la causa de muerte más frecuente en el mundo desarrollado, la mayoría de éstas se relacionan con alteraciones de las arterias coronarias, sin embargo un subgrupo de pacientes presentan como causa de isquemia cardiaca alteraciones estructurales. Material y métodos: Estudio Descriptivo. Se utilizó la base de datos recolectada en un servicio de hemodinamia de Bogotá durante dos años. Se aplicaron criterios de inclusión y exclusión y se determinaron cuatro grupos etáreos, a todos los pacientes se les practicó cateterismo cardiaco diagnóstico. Las variables analizadas fueron: diagnóstico de referencia, antecedentes y resultados del cateterismo incluyendo presencia de anomalías estructurales como las valvulopatias, el origen anómalo de las coronarias y los puentes miocárdicos. Para el análisis descriptivo se utilizó reporte de prevalencias y para el análisis de asociaciones se utilizaron tablas de contingencia y el estadístico de prueba Chi cuadrado, no se realizó análisis multivariado debido a que no se encontraron asociaciones estadísticamente significativas. Resultados: La edad promedio de los pacientes fue de 62 años (DS= 10,5), la representación del género masculino fue del 61,7%, la prevalencia de angina estable fue del 61,6%, los 3 antecedentes más prevalentes fueron: hipertensión arterial (41,4%), la hiperlipidemia (19,1%) y la Diabetes Mellitus (17,7%). La prevalencia de las alteraciones estructurales en la población de estudio de manera general fue del 12,9%, y su distribución por tipo fue: 1,4% para puentes miocárdicos, 0,7% para origen anómalo de las arterias coronarias y 10,8% de enfermedad valvular. Conclusiones: Se encontró una asociación entre los antecedentes médicos y la presencia de valvulopatias cardiacas. Se evidenció que el género no tiene relación con la presencia de alteraciones cardíacas a pesar de la mayor participación de hombres en la población de estudio. Las limitantes de este estudio se relacionaron con el tamaño de muestra, debido a la baja prevalencia de las anomalías estructurales medidas.

Evaluación de la ciencia y tecnología como instrumento de intervención del Estado en la Política Nacional de Ciencia, Tecnología e Innovación

El uso de instrumentos y directrices en la política pública para la modelación de los resultados de la actividad científica y tecnológica ha sido frecuente en el Estado colombiano. Este trabajo bajo la ‘teoría de la regulación’ de Black, examina el Modelo de Medición de Grupos de Investigación y de calificación de Revistas Científicas –Publindex- de Colciencias, como instrumentos de intervención del Estado, fundados en el uso de indicadores bibliométricos y cienciométricos. Para ello, se da respuesta a interrogantes referidos a la auto-organización de la ciencia; su relación con el Modelo de Grupos de Investigación, la influencia que dicho modelo tiene sobre la libertad de investigación; las implicaciones que tiene el otorgar categoría o status a los Grupos por actos estatales y la conveniencia de que el Estado tenga un sistema de incentivos para el examen de información científica y técnica originada en indicadores científicos, entre otros. Se busca en síntesis, aportar elementos que permitan, desde una perspectiva sistémica e interdisciplinaria explicar algunas de las razones por las cuales los elementos involucrados en la estructuración de la normativa de ciencia y tecnología, pueden inducir a afectaciones negativas y positivas en el quehacer científico y tecnológico.
