Introdução: Os traumas abdominais representam notável importância dentre as causas predominantes de morbi-mortalidade no mundo. Em se tratando de óbitos relacionados a essas lesões, estão na categoria de causas externas, as quais no Brasil representam a segunda causa geral de mortalidade, principalmente na população em idade ativa. Notadamente, traumas estão fortemente relacionados a acidentes automobilísticos, cujas taxas vêm crescendo nos últimos anos. Neles, ocorrem os politraumas, cuja região abdominal é inclusa de forma prevalente. Objetivo: a presente pesquisa tem como objetivo apresentar o perfil de óbitos os quais sejam associados a trauma abdominal e submetido ao Instituto Médico-Legal, entre os anos de 2019 até 2021. Metodologia: estudo retrospectivo, do tipo transversal, de caráter fundamentalmente quantitativo, no qual foram avaliados os laudos de óbitos decorrentes de trauma abdominal necropsiados no IML de Toledo (PR), no período de 2019 a 2021. Foram avaliadas as variáveis sexo, idade, tipo de lesão, circunstância dos óbitos e órgão mais acometido. Resultados e discussão: dos 916 óbitos trazidos à Polícia Científica de Toledo (PR) advindos de causas externas, os inclusos dentre os traumas abdominais representaram um percentual de 51,05% (n=462), no período de 2019 a 2021. Observou-se maior prevalência de óbitos por acidentes automobilísticos (68,61%), cuja causa principal foi o politrauma (37,45%). O sexo masculino fora o mais prevalente, com 84,85% (n=392), cuja faixa etária teve concentração entre os 18 aos 29 anos. Os órgãos mais lesionados foram o fígado (69,31%) e o baço (33,66%). Considerações finais: nesta amostra houve predominância de óbitos por acidentes, principalmente associados ao trauma contuso, em homens na faixa entre 18 e 29 anos, cujo órgão mais lesado fora o fígado. O conhecimento acerca do perfil de óbitos é uma importante ferramenta epidemiológica frente a possíveis intervenções, além de servir como fonte estatística para outros trabalhos do âmbito médico-legal.

Introduction: Trauma represents a notable importance among the predominant causes of morbidity and mortality in the world. When it comes to deaths related to these injuries, they are in the category of external causes, since in Brazil they represent the second general cause of mortality, especially in the working-age population. Notably, traumas are strongly related to car accidents, whose rates have been increasing in recent years. In them, polytraumas occur, whose abdominal region is prevalently included. Objective: this research aims to present the profile of deaths which are associated with abdominal trauma and hospitalized at the Instituto Médico-Legal, between the years 2019 to 2021. Methodology: retrospective, cross-sectional study, fundamentally quantitative, in which the reports of deaths resulting from abdominal trauma necropsied at the IML of Toledo (PR), from 2019 to 2021, were evaluated. The variables were gender, age, type of injury, injuries of the deaths and most affected organ. Results and removal: Of the 916 deaths brought to the Scientific Police of Toledo (PR) from external causes, those included among abdominal traumas represented a percentage of 51.05% (n=462), in the period from 2019 to 2021. there was a higher prevalence of deaths from car accidents (68,61%), whose main cause was polytrauma (37.45%). Males were the most prevalent, with 84.85% (n=392), whose age group was concentrated between 18 and 29 years. The most injured organs were the liver (69.31%) and the spleen (33.66%). Final considerations: in this sample there was a predominance of deaths from accidents, mainly associated with blunt trauma, in men aged between 18 and 29 whose most injured organ outside the liver. Knowledge about the profile of deaths is an important epidemiological tool in the face of possible interventions, in addition to serving as a statistical source for other studies in the medical-legal field.

Introducción: El traumatismo abdominal representa notable importancia entre las causas predominantes de morbimortalidad en el mundo. Cuando se trata de muertes relacionadas con estas lesiones, se encuentran en la categoría de causas externas, que en Brasil representan la segunda causa general de mortalidad, especialmente en la población en edad de trabajar. En particular, el trauma está fuertemente relacionado con los accidentes automovilísticos, cuyas tasas han aumentado en los últimos años. En ellos se producen politraumatismos, cuya región abdominal está predominantemente incluida. Objetivo: esta investigación tiene como objetivo presentar el perfil de las muertes asociadas a traumatismo abdominal y presentadas al Instituto Médico Legal, entre los años 2019 y 2021. Metodología: estudio retrospectivo, transversal, de carácter fundamentalmente cuantitativo, en el que se analizaron los reportes de muertes. resultantes de trauma abdominal autopsiado en el IML de Toledo (PR), de 2019 a 2021. Se evaluaron las variables sexo, edad, tipo de lesión, circunstancias de las muertes y órgano más afectado. Resultados y discusión: de las 916 muertes aportadas a la Policía Científica de Toledo (PR) por causas externas, las incluidas dentro de los traumatismos abdominales representaron un porcentaje del 51,05% (n=462), en el periodo 2019 a 2021. observado- hubo mayor prevalencia de muertes por accidentes automovilísticos (68,61%), cuya principal causa fue el politraumatismo (37,45%). El sexo masculino fue el de mayor prevalencia, con 84,85% (n=392), cuyo grupo etario se concentró entre 18 y 29 años. Los órganos más lesionados fueron el hígado (69,31%) y el bazo (33,66%). Consideraciones finales: en esta muestra hubo predominio de muertes por accidentes, principalmente asociados a traumatismos cerrados, en hombres con edades entre 18 y 29 años, cuyo órgano más lesionado fue el hígado. El conocimiento sobre el perfil de defunciones es una importante herramienta epidemiológica de cara a posibles intervenciones, además de servir como fuente estadística para otros trabajos médico-legales.

Mood disorders among adolescents in conflict with the law and in custody.

The high prevalence of psychiatric symptoms among juvenile delinquents is a well-replicated international finding. This study aimed to find the prevalence of mood disorders and their relationship with serious criminal acts in a population of adolescents in conflict with the law and in custody. A total of 123 male inmates aged 14 to 17 years were interviewed and assessed. Mood disorders were diagnosed in 15% of the sample for current episode and 31% for lifetime, making them third most prevalent after dependence disorders and disruptive disorders. The psychopathological profile of the adolescents who had committed violent crimes corroborates other studies reporting a high prevalence of mood disorders in this population. Several factors have been found to influence the formation of juvenile delinquency, including absence of family structure, social inequality, lack of quality school education, alcohol and drug abuse/addiction and disruptive disorders. The present results confirm mood disorders as another such factor.

Characterization of male sexual assault in the state of São Paulo, Brazil: an epidemiological study from 2014 to 2017.

Sexual violence is a pervasive global issue that affects individuals of all genders. However, the experiences of male survivors have often been marginalized and inadequately represented. Male rape, which encompasses several forms of sexual violence against men, remains a sensitive and under-discussed topic in academic literature and public discourse. This study presents a descriptive cross-sectional analysis based on data collected from the Legal Medicine Institute (IML-São Paulo, Brazil) between 2014 and 2017. The analysis includes 7386 reports of sexological examinations performed on male victims of alleged rape. The analysis reveals that a significant majority of rape reports involved victims under the age of 12 or 14, which is considered vulnerable rape by the Brazilian legislation. Regarding the examination of reported cases of abuse against men, it was observed that only the minority of these cases exhibited visible injuries consistent with rape or tested positive for the presence of spermatozoa in the perianal region. Since the absence of visible injuries or spermatozoa does not negate the possibility of rape, this work highlights the challenges in obtaining conclusive evidence, necessitating a comprehensive approach to investigate and prosecute these crimes, creating a more inclusive and supportive environment for all survivors of rape, irrespective of their gender.

Consideraciones médico-legales laborales de la fórmula de Balthazard / Occupational medical-legal considerations of the Balthazard formula

La determinación del porcentaje de pérdida en pacientes lesionados con múltiples secuelas por riesgos de trabajo resulta un verdadero reto para el perito, esto adquiere mayor relevancia cuando en el fuero judicial se pueden presentar discrepancias en los criterios para el uso o no de fórmulas matemáticas para el cálculo. La fórmula de suma combinada, creada por el Médico Forense Víctor Balthazard, no es más que un ordenamiento de una regla de tres que ordena los porcentajes otorgados a cada secuela de mayor a menor para evitar que el porcentaje final sobrepase el 100%, o bien que resulte en un porcentaje mayor que una secuela única puntuada en el baremo y que por gravedad en la intensidad de la misma resulte con un porcentaje menor al calculado por la secuela múltiple y que se ha utilizado en fueros laborales y de seguridad social alrededor del mundo. El Baremo contenido en el Código de Trabajo no establece explícitamente la forma en que se calcula el porcentaje de pérdida por secuelas múltiples, lo cual brinda libertad al perito para utilizar fórmulas, como lo es la fórmula de suma combinada, que permite calcular de forma congruente las pérdidas sucesivas sin sobrepasar a la persona más allá de su capacidad general total del 100% o de otorgar porcentajes mayores a secuelas de mayor gravedad que la suma de las pérdidas por el evento que se está valorando.

The determination of the percentage of loss in injured patients with multiple sequelae due to occupational hazards is a real challenge for the expert, this becomes even more relevant when in the judicial system there may be discrepancies in the criteria for the use or not of mathematical formulas for the calculation. The combined sum formula, created by the Forensic Physician Victor Balthazard, is nothing more than an arrangement of a rule of three that orders the percentages given to each sequel from highest to lowest to avoid that the final percentage exceeds 100%, or that it results in a higher percentage than a single sequel scored in the scale and that due to the severity in the intensity of the same results in a lower percentage than that calculated for the multiple sequel and that has been used in labor and social security courts around the world. The Schedule contained in the Labor Code does not explicitly establish the way in which the percentage of loss for multiple sequelae is calculated, which gives the expert the freedom to use formulas, such as the combined sum formula, which allows a congruent calculation of the successive losses without exceeding the person's total general capacity of 100% or to grant higher percentages to sequelae of greater severity than the sum of the losses for the event being valued.

Aproximación a la Deontología en Medicina Legal en el contexto cubano

Se realizó una revisión bibliográfica con el objetivo de exponer cuestiones deontológicas inherentes a la práctica de la Medicina Legal y el estado de la temática en el contexto nacional. Se abordan los principales conflictos éticos derivados de la práctica pericial, las recomendaciones para las actuaciones de los peritos, el desarrollo de la especialidad en el país y la situación actual respecto a las normativas deontológicas. La escuela cubana de Medicina Legal asienta su práctica en las normas jurídicas y éticas del país, con un fuerte compromiso humanista. Se concluye que, las particularidades propias de la actividad pericial, demandan la creación de un código deontológico propio.

A bibliographical review was carried out with the objective of exposing deontological issues inherent to the practice of Legal Medicine and the state of the issue in the national context. The main ethical conflicts derived from the expert practice, the recommendations for the actions of the experts, the development of the specialty in the country and the current situation regarding the deontological regulations. The Cuban School of Legal Medicine established its practice in the legal and ethical norms of the country, with a strong humanist commitment. It is concluded that the particularities of expert activity, demand the creation of its own code of ethics.

Muerte accidental por consumo combinado de cocaína y etanol Revisión bibliográfica / Accidental death from combined cocaine and ethanol use. Literature review

La autopsia médico legal en Costa Rica, en casos sospechosos de intoxicación por cocaetileno se debe realizar bajo las normas establecidas en la Guía de estándares de trabajo para la Sección de Patología Forense del Departamento de Medicina Legal. El análisis del mecanismo fisiopatológico de cómo estas sustancias provocan alteraciones en el organismo que pueden conllevar a un eventual fallecimiento corresponde a parte del análisis requerido en la investigación ante la sospecha de esta causa de muerte. Por lo anterior, el objetivo de este artículo es describir los mecanismos fisiopatológicos que ocurren durante el consumo combinado de cocaína y etanol, los mecanismos que conllevan a la muerte de personas consumidoras de estas sustancias y las consideraciones médico legales a tomar en cuenta para el diagnóstico de esta causa de muerte. Se realizó revisión de artículos científicos, sobre los efectos del uso combinado de la cocaína y el etanol. La literatura describe que el uso combinado de cocaína y etanol potencia los efectos farmacocinéticos y bioquímicos de cada una de estas sustancias, que su derivado, el cocaetileno, es capaz de generar por sí mismo los mecanismos causantes de la muerte. Que los principales mecanismos fisiopatológicos que conllevan la muerte ante el uso combinado de estas sustancias son de origen cardiovascular y hepático. Como consideraciones médico legales a tomar en cuenta para el diagnóstico de esta manera de muerte accidental, en la Sección de Toxicología del Departamento de Ciencias Forenses de Costa Rica, la cuantificación del cocaetileno y las sustancias relacionadas no se realiza, aunque se encuentra actualmente en el desarrollo de un proyecto para la determinación de la estabilidad de las drogas en sangre bajo las condiciones de almacenamiento, con el fin de ofrecer la posibilidad de cuantificar ciertas drogas (en donde se podría incluir el cocaetileno) en un futuro próximo.

Medical-legal autopsy in Costa Rica, in suspected cases of cocaethylene poisoning must be performed under the regulations established in the Work Standards Guide for the Forensic Pathology Section of the Department of Legal Medicine. The analysis of the pathophysiological mechanism of how these substances cause alterations in the organism that can lead to eventual death corresponds to part of the analysis required in the investigation when this cause of death is suspected. Therefore, the objective of this article is to describe the pathophysiological mechanisms that occur during the combined consumption of cocaine and ethanol, the mechanisms that lead to the death of people who consume these substances, and the medico-legal considerations to be considered for the diagnosis. of this cause of death. A review of scientific articles was carried out on the effects of the combined use of cocaine and ethanol. The literature describes that the combined use of cocaine and ethanol enhances the pharmacokinetic and biochemical effects of each one of these substances, that its derivative, cocaethylene, can generate the mechanisms that cause death by itself. That the main pathophysiological mechanisms that lead to death in the combined use of these substances are of cardiovascular and hepatic origin. As legal medical considerations to take into account for the diagnosis of this type of accidental death, in the Toxicology Section of the Department of Forensic Sciences of Costa Rica, the quantification of cocaethylene and related substances is not carried out, although it is currently in the development of a project for the determination of the stability of drugs in blood under storage conditions, in order to offer the possibility of quantifying certain drugs (which could include cocaethylene) in the near future.

¿Es el "diente rosado" válido en el contexto forense actual? / Are "pink teeth" relevant to current forensics?

Introducción: El "diente rosado" es un fenómeno post mortem. Se caracteriza por una tonalidad rosa, rojiza y hasta púrpura, que puede observarse en los dientes. Su primera referencia se remite a 1829, cuando Thomas Bell lo describió, y genera polémica desde hace casi dos siglos. La temática plantea varias interrogantes: ¿sería más lógico nombrarlo "red teeth" o "purple teeth"?, ¿qué provoca esa tonalidad más intensa?, ¿la coloración rosada indica determinada causa de muerte?, ¿queda para siempre o puede desaparecer por diversos factores? Objetivo: Describir los indicadores de que el "diente rosado" o "pink teeth" pueda aún ser considerado un elemento importante para la investigación forense actual. Comentarios principales: Luego de la experiencia acumulada con los casos trabajados durante los últimos 20 años y la revisión bibliográfica realizada, se evidencia que el fenómeno aparece sobre todo en las piezas dentales anteriores y premolares monorradiculares. Además, puede verse tanto ante mortem como post mortem. Por causas diferentes el post mortem necesita de varios días para instaurarse y es un evento tafonómico, evidenciable tanto en muertes violentas como naturales, aunque la variación en su tonalidad depende de diversos factores. Consideraciones globales: Teniendo en cuenta la experiencia obtenida por los autores, y lo referido en la bibliografía sobre el tema, se evidencia que este signo, fenómeno o hallazgo (al aclararse las interrogantes planteadas) aún puede ser muy significativo y orientador en el contexto forense actual(AU)

Introduction: "Pink teeth" are a post-mortem phenomenon characterized by a rose, reddish and even purple shade of color which may be observed in teeth. Their first reference dates back to 1829, when Thomas Bell described them. They have been a topic of debate for almost two centuries. The subject poses several questions: Would it be more logical to name them "red teeth" or "purple teeth"? What causes the increase in color intensity? Does the pink shade signal a specific cause of death? Does it remain forever or may it disappear for a variety of reasons? Objective: Describe the indicators that "pink teeth" may still be considered an important element in current forensic research. Main remarks: Based on the experience gathered from the cases analyzed in the last 20 years and the bibliographic review conducted, it is evident that the phenomenon appears mainly in anterior teeth and single-rooted premolars. On the other hand, pink teeth may be observed ante mortem as well as post mortem. For a number of reasons, post mortem pink teeth take several days to form, and they are a taphonomic phenomenon, present in violent as well as natural deaths, though their change in tone depends on various factors. General considerations: Founded on the experience obtained by the authors and the bibliography about the topic, it is evident that this sign, phenomenon or finding (upon clarification of the questions posed) may still be very significant and enlightening in the current forensic context(AU)

Forensic entomology in research and practice: an overview of forensic experts' perceptions and scientific output in Brazil.

Given the growing demands for standardization of procedures for collection, preservation, and identification of insect specimens, this study aimed to identify how forensic entomology is used in Brazil and the perceptions of professionals involved in this process. We conducted: (1) bibliometric survey of the scientific production of forensic specialists from 2001 to 2020; (2) questionnaire applied to forensic professionals to verify their perceptions about the use of entomological evidence in practice. An increase in publications on Forensic Entomology was noticed in the last 5 years, mainly in the South and Northeast regions. Of the 82 respondents to the questionnaire, 62.8% deal with cadavers at least once a week, but 89.0% of the professionals who examine cadavers weekly find less than 10.0% colonized by insect larvae. Using entomological evidence to estimate PMI was mentioned by only 36.6% of the professionals. Most respondents stated no procedures related to collecting, handling, or identifying necrophagous insects in their daily practice. Regarding the chain of custody, 64.6% said they were aware of the changes in the regulations involving the collection and maintenance of forensic evidence. We emphasize the importance of collaboration between scientists at universities and crime scene examiners. Although the use of entomological evidence in criminal investigations in Brazil is still scarce, a growing interest in this area can be detected among forensic experts.

Physical evidence of rape against children and adolescents in Brazil: Analysis of 13,870 reports of sexual assault in 2017.

Introduction: The medical literature reports child and adolescent maltreatment since the 8th century. Unfortunately, even today, the incomplete knowledge of this event persists. Several forms of violence are applied to children and adolescents, mainly sexual violence including rape and sexual assault. Forensic medical examinations routinely include the genital area, anus, and the body of the victims for signs of a recent or old injury. The main goal of this study is to show the results of physical and sexual examinations regarding confirmation of rape in children and adolescents, based on the medicolegal reports. Methods: We made a descriptive cross-sectional study conducted by collecting data from Medicolegal Institute (IML-São Paulo, Brazil) in 2017. We examined 13,870 reports of sexological examinations of victims of the alleged rape. The variables analyzed were age; sex; physical examination; sexological examination; and direct search for sperm in the vaginal, anal, or oral cavity. We selected 11,725 reports from victims under 18 years. Results: As for the medical-legal findings, only 1735 reports (14.8%) confirmed sexual abuse. The most affected ages were between 3 and 5 years in the male group and 11 to 14 years in the female group. The most frequent injuries were bruises and abrasions, fissures in the anal region. In 96.2% of the examined males and 85.8% of the females under 14 years old, the examination was inconclusive, and somebody cannot prove the alleged rape. Only 1735 reports (113 from men and 1622 from women) concluded beyond any doubt the alleged rape (14.8%). The search for sperm was positive in only 1582 cases (13.5%). Conclusion: This study shows that the results of the medicolegal examinations were quite limited in recording evidence. Sexual violence against children and adolescents reaches mostly females under 13 years of age. Besides, it is a complicated crime to prove, as 85.8% of female examinations and 96.2% of male exams revealed: "no supporting elements" or "undetermined" to characterize the felony. Therefore, to prevent it, the communication of the alleged rape must be made as quickly as possible.

Análisis médico legal de la toxicomanía por MDMA: reporte de caso / Medical-legal relationship of MDMA drug addiction: case report

Resumen El análisis por toxicomanía representa un proceso común solicitado por la Autoridad Judicial para determinar si un usuario presenta hallazgos compatibles con el uso de una droga a nivel clínico, componentes histológicos, patológicos y toxicológicos que puedan generar su uso. Es necesario destacar las limitaciones del ambiente clínico donde se pueden generar múltiples hallazgos, y de la toxicología forense donde a pesar de la especificidad a la que se asocia; también se encuentra limitada por la capacidad de sus equipos tecnológicos. La resonancia magnética nuclear cuantitativa de hidrógeno representa grandes ventajas al demostrar la presencia de una droga ilegal, así como la posibilidad de disminuir costos y tiempo laboral. El uso del MDMA como tratamiento con una reciente aprobación para un estudio de fase III por la FDA, también requiere que se valore el motivo de su uso, por lo que para realizar un análisis médico legal se contemplaron diversos elementos de juicio a fin de satisfacer la evaluación sobre la toxicomanía por MDMA en un usuario que presentó un tejido granular blanco tipo polvo en la sección distal del tabique nasal y negó el consumo de metanfetaminas.

Abstract The analysis for drug addiction represents a common process requested by the Judicial Authority to determine if a user presents findings compatible with the use of a drug at a clinical level, histological, pathological and toxicological components that may generate its use. It is necessary to highlight the limitations of the clinical environment where multiple findings can be generated, and of forensic toxicology where despite the specificity to which it is associated; it is also limited by the capacity of its technological equipment. Quantitative hydrogen nuclear magnetic resonance represents great advantages when demonstrating the presence of an illegal drug, as well as the possibility of reducing costs and labor time. The use of MDMA as a treatment with a recent approval for a phase III study by the FDA, also requires that the reason for its use be assessed, therefore, in order to carry out a legal medical analysis, various elements of judgment were considered in order to satisfy evaluation of MDMA drug addiction in a user who presented with white powder-like granular tissue in the distal section of the nasal septum and denied the use of methamphetamine.

Identification of victims of the collapse of a mine tailing dam in Brumadinho.

The collapse of the B1 Dam of VALE SA mining company in Brumadinho, Minas Gerais, Brazil was the largest humanitarian disaster and occupational accident in the country's history, and it posed challenges regarding the management and identification of multiple victims. We evaluated the impact of the iron ore tailings on the victims' bodies. We examined the scientific identification of the victims and the dynamics of the disaster over the 1st year after it occurred. We also determined the socio-demographic profiles of the victims. In this retrospective, cross-sectional study, we investigated the expert reports of the victims' biological remains from 25 January 2019 to 25 January 2020. We analysed the socio-demographic data, identification methods, identification status, identification time, and necroscopic information. During the study period, 259 of 270 victims were identified, and 603 biological materials were analysed; among them, 86.2% were body parts and 13.8% were whole bodies. Of the total cases registered that year, 476 (78.9%) were submitted during the first 10 weeks after the disaster. Friction ridge analysis accounted for 67.9% of primary identifications and DNA analysis did so for 91.6% of re-identification cases. Body dismemberment was 3.4 times greater among mine workers than among community victims. Adult males accounted for the greatest number of victims (P < 0.001). Polytraumatic injury was the prevalent single cause of death. Necropsy examination revealed the occurrence of asphyxia in 7% of cases. The higher number of fatalities and greater dismemberment among employees than with community residents underlines the occupational dangers in the mining industry and clarifies the dynamics of the disaster. In the initial weeks after the dam collapsed, friction ridge analysis was the most appropriate method for identification. Subsequently, DNA analysis became the most-used technique for identification and re-identification owing to the great volume of body parts and decomposed biological tissue. Autopsy allowed diagnosis of the causes of death to be clarified according to the Brazilian criminal legal system.

Case Report: Depression × dementia with Lewy bodies in the elderly: The importance of differential diagnosis.

Background: Dementia is a clinical syndrome which is more common in elderly people. Dementia with Lewy bodies (LBD) is not so rare in elderly people, with cognitive impairment in about 30% over age 65. The clinical picture is characterized by fluctuation in cognitive functions, recurrent, well-formed, detailed visual hallucinations, and Parkinsonism, with rigidity, tremor, bradykinesia, and slurred speech. Case presentation: We present a case report of LBD in a 73-year-old retired teacher, which a initial wrong diagnosis of refractory depression for at least 3 years. We also conduct a review of recent works on theme. Conclusion: LBD diagnosis can be neglected for years, with a legal and clinical issues to patients and their families. Detailed medical research, including differential diagnosis, are very necessary on those cases, specially when they are called refractory. We encourage new research and adequate clinical training to prevent damage.

As part of its achievements, the anthropological classification and characterization of a part of the materials from the bone collection of the University of Medical Sciences of Matanzas was carried out, as well as its expansion through a physical anthropology section that incorporated six complete corpses anthropologically characterized. Conclusions: This training allowed to train and update the students on human identification, based on the study of bone remains referring to the qualitative and quantitative expression of morphological characters, which respond to the needs of teaching practice in Anatomy, as well as in legal-medical assistance(AU)

Las Neurociencias Forenses: El nuevo Paradigma Penal / Forsensic Neurosciences: The New Criminal Paradigm

Resumen Las neurociencias están en medio de un resurgimiento del interés en la dimensión biológica de los estados mentales y la conducta humana, aún más con su introducción en el ámbito ce la criminología biosocial y el sistema penal. La introducción de nuevas disciplinas en el ámbito penal representa un reto al momento de validarlas como una herramienta útil para el proceso, dado que cada vertiente tendrá puntos a favor y en contra de ellas, por lo cuál es fundamental analizar de forma crítica la utilidad, viabilidad y grado de certeza que ofrezcan dichas disciplinas. Al margen de las neurociencias forenses, resulta predominante analizarlas de forma integral, biológica, psicológica, ética y legal, con la finalidad de que las aportaciones que esta rama ofrezca al estado de derecho sean objetivas y aptas para el sistema penal de cada circunstancia temporal y social en que se implementen.

Abstract Neurosciences are in the midst of a resurgence of interest in the biological dimension of human mental states and behavior, even more so with the introduction of biosocial criminology and the penal system into the field. The introduction of new disciplines in the criminal field represents a challenge when validating them as a useful tool for the process, given that each aspect will have points for and against them, which is why it is essential to critically analyze the usefulness, viability and degree of certainty offered by these disciplines. Apart from forensic neurosciences, it is predominant to analyze them in an integral, biological, psychological, ethical and legal way, so that the contributions that this branch offers to the rule of law are objective and suitable for the criminal system of each temporary and social circumstance in which they are implemented.

Reporte de un caso: Muerte súbita de Origen Ginecoobstétrico / Sudden death of gyneco-obstetric origin: Case report

Resumen La muerte súbita de origen ginecoobstétrico es poco frecuente tanto en paises americanos como del viejo continente, sin embargo, este tipo de defunciones es por concepto relevante para la legislación de Costa Rica al ser criterio de autopsias médico legales, donde se responde no solo la causa de muerte, sino también otros objetivos propias de la necropsia, como la manera de muerte, donde debe descartarse una diferente a la natural. Los embarazos ectópicos rotos tienen significancia en los registros actuales según la razón de mortalidad materna, con repercusión en la salud reproductiva de las pacientes que lo padecen, convirtiéndose en una patología relevante para el registro médico clínico como forense.

Abstract Sudden death of gyneco-obstetric origin is rare in both American countries and the old continent, however, this type of death is conceptually relevant to Costa Rican legislation as it is the criterion of medical-legal autopsies, where not only the cause is answered of death, but also other objectives typical of the autopsy, such as the way of death, where one other than the natural one must be ruled out. Broken ectopic pregnancies are significant in current records according to the reason of maternal mortality, with repercussions on the reproductive health of patients who suffer from it, becoming a relevant pathology for clinical medical and forensic records.

Fracturas atípicas de fémur asociadas al uso de bifosfonatos / Bisphosphonate associated atypical femur fractures

Resumen Los bifosfonatos son medicamentos ampliamente conocidos por su efecto antagonista de la resorción ósea y la consecuente reducción del riesgo de fracturas en los pacientes con osteoporosis. La literatura actual provee evidencia en términos de datos clínicos y experimentales que asocian el uso prolongado de estos medicamentos con un aumento en el riesgo de fracturas atípicas de fémur. Para establecer si esta asociación es clínicamente relevante, se requiere realizar estudios posteriores que incluyan la relación entre otros factores que podrían influir en la aparición de este tipo de fracturas como lo es la propia enfermedad osteoporótica, el tipo de bifosfonato utilizado, el mecanismo lesional que originó la fractura, medicamentos concomitantes y patologías asociadas.

Abstract Bisphosphonates are medications that are widely known for their antagonizing effect on bone resorption and their consequent reduction in the risk of fractures in patients with osteoporosis. Current literature provides evidence in terms of experimental and clinical data associating prolonged use of these drugs with an increase in the risk of atypical femur fractures. To establish if this association is clinically relevant, there lies a need for further studies that take into account other factors that might influence the occurrence of these type of fractures, like the osteoporotic disease itself, age, intake of other drugs and associated systemic illnesses.

Intoxicación por tolueno / Toluene poisoning

Resumen El ser humano está inmerso en un entorno donde inhala, ingiere o absorbe muchas sustancias químicas, de las cuales toman relevancia las exposiciones en los lugares de trabajo y las que causan la muerte en la práctica médico forense. El tolueno es un inhibidor neuronal asociado con daño progresivo del sistema nervioso central y periférico, su toxicidad puede ocurrir por inhalación involuntaria o deliberada y puede llevar incluso a la muerte. Se realizó una revisión bibliográfica en diferentes bases de datos, de los artículos publicados referentes al tema de los últimos ocho años, con el objetivo de revisar las características del químico, el metabolismo, las intoxicaciones agudas y las crónicas, así como sus implicaciones letales. Se concluye que para mejorar la pericia médico legal, al valorar casos de intoxicacion por tolueno se deben de contemplar los criterios de causalidad en los casos de enfermedad laboral y en sospecha de causa de muerte es fundamentantal el resultado toxicológico ante la ausencia de hallazgos específicos en la autopsia.

Abstract The human being is immersed in an environment where he inhales, ingests or absorbs many chemical substances, in forensic medical practice the exposures in the workplace and those that cause death take on relevance. Toluene is a neuronal inhibitor associated with progressive damage of the central and peripheral nervous system, its toxicity can occur by involuntary or deliberate inhalation and can even lead to death. A bibliographic review was carried out in different databases, of the published articles referring to the subject of the last eight years, with the objective of reviewing the characteristics of the chemical, the metabolism, both acute and chronic poisoning and its lethal implications. It is concluded that to improve the legal medical expertise when assessing cases of toluene poisoning, causality criteria must be considered in cases of occupational disease and in suspected cases of death the toxicology result is fundamental in the absence of specific findings in the autopsy.
