Un gran número de intoxicaciones agudas letales se producen en el país debido al uso indebido de métodos químicos para el control de plagas. Sin embargo, no se encuentran implementados protocolos confiables para establecer el diagnóstico de intoxicaciones agudas producidas por agentes de control de plagas como los fitosanitarios, que contribuyan a brindar información a los tribunales de justicia para establecer la etiología tóxica. En respuesta a lo anteriormente descrito, en el presente trabajo se implementaron protocolos analíticos para la investigación de productos fitosanitarios en muestras biológicas postmortem. Se establecieron protocolos y se implementaron metodologías analíticas para la determinación cualitativa o cuantitativa de un grupo de pesticidas organofosforados (paration, metil paration y diazinon) y del tipo carbamatos (carbaril, methomil y aldicarb) en muestras ingresadas en el departamento de laboratorios del Instituto Médico Legal de Santiago de Chile, y procedentes del departamento de Tanatología. Las metodologías analíticas se basaron en un pre-tratamiento de las muestras de acuerdo a su naturaleza, extracción en fase sólida (SPE) y análisis cromatográfico con detectores de nitrógeno-fósforo (GC-NPD) y de espectrometría de masas (GC-MS). Estas metodologías fueron validadas y favorablemente comparadas en su eficiencia con respecto a aquellas existentes en el servicio. Este nuevo pre-tratamiento, asociado ahora con SPE, permitió obtener muy buenos resultados tras la aplicación de cromatografía en placa fina (TLC) con derivatización post-cromatografica, para identificar pesticidas organofosforados en contenido gástrico y carbamicos en sangre y contenido gástrico. Al mismo tiempo se implementó un método analítico adecuado para la cuantificación de pesticidas organofosforados en la matriz sangre (paration, metilparation y diazinon), mediante la aplicación de SPE y GC-NPD. Se obtuvieron las curvas de calibración para determinar los pesticidas organofosforados en la matriz sangre, en el intervalo de concentraciones comprendido entre 0,1 y 4,0 mg/L, lográndose coeficientes de determinación superiores a 0,99 para los tres pesticidas organofosforados. Los limites de detección (LOD) y cuantificación (LOQ) obtenidos con esta metodología se encuentran entre 0,05-0,06 mg/L y 0,17-0,19 mg/L respectivamente. Estos valores son adecuados de acuerdo a las concentraciones que se logran obtener en sangre luego de una intoxicación aguda por pesticidas, según la experiencia forense mundial. La recuperación de los pesticidas organofosforados desde las muestras de sangre fue superior o igual al 95%, con valores de repetibilidad menores o iguales a 6,5%, indicando un bajo grado de dispersión para el método. Al mismo tiempo se evaluó la precisión intermedia obteniéndose valores inferiores o iguales a 6,9% (RSD), siendo menores al máximo de 15% establecido como límite. Los parámetros de calidad del método analítico desarrollado se enmarcan dentro de los valores aceptados para una metodología destinada al análisis de muestras de sangre del tipo post-mortem, avalados por literatura internacional. La importancia del desarrollo e implementación de esta metodología de trabajo para el Servicio Médico Legal tiene un alto impacto debido a que se trata de los compuestos (pesticidas organofosforados y carbamicos) que estadísticamente se presentan con mayor frecuencia en las causas de muerte por intoxicación aguda por pesticidas (IAP). En consecuencia, esta metodología será una valiosa contribución al informe tanatológico final que debe presentar el médico ante los tribunales de justicia, cuando se encuentra frente a un caso por muerte por intoxicación por pesticidas.
A great number of lethal acute intoxications take place in the country due to the undue use of chemical methods for the control of plagues. However, reliable protocols are not implemented to establish the diagnosis of acute intoxications taken place by agents of control of plagues, as the phytosanitary, that contribute to offer information to the tribunals of justice to establish the toxic etiology. In answer to these facts, in this work were implemented analytical protocols for the investigation of products phytosanitary in biological postmortem samples. It were established and implemented analytical methodologies for the qualitative or quantitative detection of a group of organophosphorus pesticides (parathion, parathion methyl and diazinon) and carbamates (carbaril, methomil and aldicarb) in samples entered in the department of laboratories of the Legal Medical Institute of Santiago from Chile, and coming from the department of Tanatology. The analytical methodologies were based on a pre-treatment of the samples according to their nature, solid phase extraction and chromatographic analysis with nitrogen-phosphorus (GC-NPD) and mass spectrometry detectors (GC_MS). These methodologies were validated and favorably compared in their efficiency with regard to those existent ones in the service. This new sample treatment, associate now with SPE, allowed to obtain very good results after the application of thin layer chromatography (TLC) with postchromatographic derivatization, to identify organophosphorus pesticides in gastric content and carbamates in blood and gastric content. At the same time a suitable analytical method for the quantification of organophosphorus pesticides in blood samples was implemented (parathion, metilparathion and diazinon), by means of the application of SPE and GC-NPD. The calibration curves for determining the organophosphorus pesticides in blood samples were obtained between 0.1 and 4.0 mg/L, with coefficients of determination higher than 0.99 for the three organophosphorus pesticides. The limit of detection (LOD) and quantification (LOQ) obtained with this methodology ranged 0.05-0.06 mg/L and 0.17-0.19 mg/L, respectively. These values are adequate taking into account the concentrations reached in blood after an acute poisoning by pesticides, according to world-wide forensic experience. The recovery of the organophosphorus pesticides from the blood samples was higher or equal than 95% with values of repeatability lower or equal than 6.5% indicating a low degree of dispersion for the method. At the same time the intermediate precision showed values lower or equal than 6.9% (RSD), being lower than the maximum of 15% establishes as the limit. The quality parameters of the analytical method developed are within the ranges of acceptance for a methodology aimed to the analysis of blood samples of the type post-mortem examination, and are warranted by international literature. The importance of the development and implementation of this methodology of work for Legal Medical Service has a high impact because it is the compounds (organophosphorus and carbamates pesticides) that statistically appear most frequently in the death causes by acute poisoning by (IAP). As a consequence, this methodology will be a valuable contribution to the report that it must present the doctor before the justice courts, when as opposed to a case by death by poisoning by pesticides.

Resumo: A estimativa do intervalo pós-morte (IPM), período entre a ocorrência da morte e o momento em que o corpo ou carcaça é encontrado, é uma das principais utilizações de insetos na área forense. A partir de informações sobre a biologia, ecologia e distribuição geográfica dos insetos, bem como do comportamento de toda fauna presente em um corpo é possível estimar o menor intervalo da ocorrência da morte. Diversos fatores tais como temperatura, umidade, presença de substâncias tóxicas nos tecidos de uma carcaça, podem interferir no ciclo de vida de um inseto, afetando diretamente a estimativa do IPM quando esta é baseada em parâmetros biológicos do inseto. Por isso, múltiplos fatores devem ser considerados para que a perícia seja mais precisa. Com o aumento no número de mortes de animais de importância econômica devido à intoxicação medicamentosa, se faz necessárias pesquisas voltadas para a entomotoxicologia, uma área que carece de estudos específicos. Assim, o presente trabalho visou identificar a entomofauna associada a carcaças de cabras (Capra aegagrus hircus L.) mortas após tratamento com ivermectina, expostas em ambiente natural, além de averiguar possíveis diferenças na atratividade, no desenvolvimento dos imaturos que utilizaram esse substrato para alimentação e se a temperatura e o padrão de colonização da massa larval divergem entre as carcaças de animais mortos por intoxicação. Esse último parâmetro foi avaliado por meio de registros termográficos realizados em intervalos de 12 horas. Além da importância de fatores abióticos como luminosidade, temperatura, umidade e pluviosidade, pôde-se observar a ação da ivermectina nas carcaças tratadas, interferindo na composição da fauna colonizadora, no tempo total e em cada estágio da decomposição, assim como no padrão físico e comportamental das massas larvais em comparação ao grupo controle. Ainda foi demonstrado que a termografia pode ser utilizada como uma nova ferramenta em estudos periciais, auxiliando de forma significativa a avaliação dos parâmetros das massas larvais
Abstract: The estimation of the postmortem interval (PMI), period between the occurrence of death and the time at which the body or casing is found, is one of the main uses of insects in the forensic field. Using information on the biology, ecology and geographical distribution of insects, as well as the behavior of the entire fauna present in a body, is possible to estimate the time of death. Several factors such as temperature, humidity, presence of toxic substances in the tissues of a carcass, may interfere with the life cycle of an insect, directly affecting the estimate of PMI when it is based on biological parameters of the insect. Therefore, multiple factors should be considered so that the forensic analysis is more accurate. With the increase in the number of animal's deaths of economic importance due to drug intoxication, becomes necessary a research on entomotoxicology, an area with lack of specific studies. Thus, the present study aimed to identify the insect fauna associated with carcasses of goats (Capra aegagrus hircus L.) killed after treatment with ivermectin and exposed in the natural environment. Still, investigate possible differences in attractiveness, the immature development that used this substrate for feeding and if the temperature and the colonization pattern of larval mass differ between carcasses of animals killed after ivermectin inoculation. This last parameter was evaluated by thermographic shots performed at intervals of 12 hours. Besides the importance of abiotic factors such as luminosity, temperature, humidity and rainfall, the action of ivermectin on carcasses couse interferense in the composition of the colonizing fauna, the total time of colonization and the time of the decomposition stages, as well as the physical patterns and behavior of larval masses compared to the control group. Although it has been shown that thermography can be used as a new tool in forensic studies, helping to evaluate the parameters of larval mass

Full textA farmacogenética é a ciência que estuda a influência da componente genética nas respostas a tratamentos farmacológicos. Estas podem variar entre indivíduos devido a vários fatores, sendo um deles a ocorrência de polimorfismos em genes que codifiquem proteínas envolvidas no metabolismo, transporte do fármaco ou que sejam o alvo da ação farmacológica. Os estudos farmacogenéticos têm desempenhado um importante papel na área da toxicologia forense uma vez que acrescentam informações que podem auxiliar na identificação da causa e circunstância da morte, especialmente nos casos em que as concentrações de fármacos encontradas nas análises toxicológicas post mortem são difíceis de interpretar. Estas informações adicionais servem essencialmente para determinar se a morte foi intencional ou acidental, tendo sido publicados vários casos que o demonstram. No entanto, estes estudos apresentam ainda bastantes limitações e são necessárias mais evidências científicas para que sejam implementados na rotina médico-legal e possam ser usados como evidência em tribunal. Apesar deste facto, é amplamente reconhecido que os polimorfismos genéticos podem desempenhar um relevante papel nas mortes e isto alerta para a necessidade da realização de estudos farmacogenéticos aquando da prescrição médica de forma a evitar que tal aconteça. Pharmacogenetics is the science that studies the influence of genetic component in responses to pharmacological treatments. These can vary between individuals due to various factors, one being the occurrence of polymorphisms in genes encoding proteins involved in metabolism, transport of the drug or are the target of pharmacological action. The pharmacogenetics studies have played an important role in the field of forensic toxicology since it adds information that can help to conclude about the cause and manner of death in cases where drugs are found in certain concentrations and thus toxicological results are not clear. This additional information should primarily serve to distinguish intentional and accidental causes and there are several published cases that show that. However, these studies still have many limitations and are needed more scientific evidence before can be implemented in forensic routine and can be used as evidence in court. Despite this fact, there is evidence that genetic polymorphisms may play a role in the deaths and this points to the need of conducting pharmacogenetics studies on prescription to avoid that.

Full textOs pesticidas são substâncias destinadas a prevenir, destruir ou controlar pragas. No entanto, estes produtos são também responsáveis por intoxicações em seres humanos. Em Portugal, mais de metade das intoxicações voluntárias com pesticidas envolvem inseticidas organofosforados (IOFs). Neste trabalho, pretendeu-se desenvolver e validar um conjunto de metodologias para a determinação analítica de dez IOFs, nomeadamente, clorfenvinfos, clorpirifos, diazinão, dimetoato, fentião, fosalona, malatião, paratião, pirimifos-metilo e quinalfos, em amostras de sangue total e de conteúdo gástrico, tendo em vista a introdução das mesmas na rotina pericial do Serviço de Toxicologia Forense da Delegação do Norte do Instituto Nacional de Medicina Legal e Ciências Forenses, I.P. (STF-N). Foram testados métodos de extração de IOFs com Extração em Fase Sólida (SPE) em amostras de sangue com colunas Oasis® HLB e Sep-Pak® C18 e com separação e deteção por GC-ECD e GC-MS. O método de extração com colunas Sep-Pak® C18 foi selecionado, uma vez que no final do processo de extração e análise foram gerados sinais cinco vezes superiores aos obtidos após extração com as outras colunas de SPE, e mostrou ser seletivo para isolamento dos analitos e do padrão interno (etião) em amostras de sangue postmortem. Foram preparadas curvas de calibração entre 50 e 5000 ng/mL, utilizando modelos de regressão linear ponderada. Devido à sensibilidade mais baixa do detetor, não foi possível definir uma gama de trabalho para o fentião por GC-ECD, enquanto para o pirimifos-metilo esta foi estabelecida entre 500 e 5000 ng/mL. O limite de quantificação foi 50 ng/mL para todos os analitos, à exceção do pirimifos-metilo por GC-ECD (500 ng/mL). A eficiência de extração média situou-se entre os 72 e os 102%. Após testes com Extração Líquido-Líquido (LLE) e/ou SPE, o procedimento adotado para rastreio/confirmação qualitativa de IOFs em amostras de conteúdo gástrico, consistiu num passo de LLE com éter dietílico, evaporação do solvente e retoma do extrato em acetonitrilo, seguido de SPE com colunas Sep-Pak® C18 e da análise por GC-MS ou por GC-ECD. Obtiveram-se eficiências de extração médias entre 40 e 50% e limites de deteção de 10 μg/mL para todos os IOFs, exceto para o fentião por GC-ECD. Os métodos desenvolvidos foram considerados robustos e adequados ao propósito, tendo sido já adotados na rotina do laboratório do STF-N.
Pesticides are substances intended to prevent, destroy and control plagues. However, these products are also responsible for intoxications in humans. In Portugal, more than half of pesticide intoxications involve organophosphorus insecticides (OPs). In this thesis we intended to develop and validate methodologies for the determination of ten OPs, namely, chlorfenvinphos, chlorpyrifos, diazinon, dimethoate, fenthion, phosalone, malathion, parathion, pyrimiphos-methyl and quinalphos, in whole blood and gastric content samples, aimed at being included in routine procedures of Forensic Toxicology Laboratory of North Delegation of National Institute of Legal Medicine and Forensic Sciences (FTL-N). In blood, were tested three procedures of Solid Phase Extraction (SPE) for OPs with Oasis® HLB and Sep-Pak® C18 cartridges, followed by GC-ECD and GC-MS analysis. The Sep-Pak® C18 cartridges extraction procedure was selected because the samples prepared using that SPE cartridges generated signals 5 times higher than those obtained with the two different Oasis® HLB cartridges. The method was shown to be selective for the isolation of selected OPs as well as the internal standard (ethion) in postmortem blood samples. Calibration curves Were prepared between 50 and 5000 ng/mL using weighted linear regression models. Due to the lower sensitivity of the detector it was not possible to establish a working range for fenthion by GC-ECD, whereas for pirimiphos-methyl it was set between 500 and 5000 ng/mL. The limit of quantification was 50 ng/mL for all analytes, except for pirimiphos-methyl by GC-ECD analysis (500 ng/mL). The average extraction efficiency was obtained between 72 and 102%. After tests with Liquid-Liquid Extraction (LLE) and/or SPE, the procedure adopted for detection and qualitative confirmation of OPs in gastric content samples consisted in LLE with diethyl ether, solvent evaporation, recovery of the extract with acetonitrile, and SPE with Sep-Pak® C18 cartridges, followed by GC-ECD and GC-MS analysis. Average extraction efficiencies 40 and 50%, and detection limits of 10 μg/mL were obtained by GC-ECD, except for fenthion. The developed methods were considered robust and fit for the purpose, and were already adopted in routine analysis of FTL-N.

Full textBarbiturates are a class of drugs that act as central nervous system depressant and are associated with high numbers of poisoning cases and non-medical use in several countries. In Brazil, phenobarbital is the most related antiepileptic drug involved in intoxication cases. Patients report that \"this drug is a substance with strong action in the brain.\" In fact, barbiturates are highly related to attempted suicide and homicide cases, in which quantification of these substances to correlate with the possible cause of death is necessary. However, postmortem toxicological analyses are difficult to perform and interpret, because the concentration of toxic agents found is quite complex and affected not only by deterioration condition of the body but also by a process known as postmortem redistribution. In general, higher concentrations are found in the blood located in central sites (e.g. heart cavity) compared with the levels found in peripheral vessels (such as the femoral vein). In other cases, the time between death and postmortem examination is enough for some substances that would normally be present in the blood are no longer available in this biological fluid. Besides, there are few reference values for most non-conventional biological samples, making it difficult to interpret the results. The objective of this work was the development and application of methods for identification of barbiturates (butalbital, secobarbital, pentobarbital and phenobarbital) in postmortem samples (heart blood, femoral blood and liver). The analytes were extracted by using liquid-phase micro extraction (LPME) and quantified by gas chromatography-mass spectrometry (GC-MS). After the development and validation, analytical methods were applied in real cases of eleven corpses autopsied by Death Verification Service of São Paulo City (USP-SVO), with suspected of barbiturates involvement. Nine cases were positive for phenobarbital. The mean ratio of blood femoral / cardiac blood was 0.91 with a standard deviation of 0.23. For the correlation liver / femoral blood the average was 1.17 with a standard deviation of 1.29. Barbiturates were chosen as model for this study because the high incidence of cases of acute poisoning with these drugs in Brazil.

Full textIn the first chapter of this thesis, general aspects on forensic toxicology and capillary electrophoresis are presented, aiming to show how the analytical technique can be useful for forensic applications. The second chapter presents the development of analytical methodology based on capillary electrophoresis with diode array detection for determining drugs of abuse and/or their biotransformation products in vitreous humor. Parameters such as the composition of background electrolyte (with special attention to the phenomenon of electrodispersion), online pre-concentration (stacking) and sample preparation procedures were objects of study. The complete electrophoretic separation of 12 investigated analytes was obtained within 10 minutes of run. The validation parameters of the method have shown that this is perfectly applicable to toxicological analyses with forensic purposes. The third chapter presents the elaboration of analytical methodology based on capillary electrophoresis coupled to mass spectrometry for determining cocaine and five biotransformation products in urine, with simple sample preparation. The process developed presented adequate sensitivity for the verification of acute intoxications by cocaine, and mass spectrometry contributed with great selectiveness to the analysis, mainly when the detection was conducted by the selection of the molecular-ion and fragments generated at 34% of collision energy. The fourth chapter presents the development of a simple and quick method for determining MDMA in tablets of Ecstasy using capillary zone electrophoresis. In the running condition, it is possible to determine the concentration of MDMA in less than two minutes (using procaine with internal standard). The method developed was compared with the one routinely used at Núcleo de Análise Instrumental do Instituto de Criminalística de São Paulo, based on high performance liquid chromatography with fluorescence detection. The electrophoretic method developed was five times faster than the reference one, allowing higher productivity without loss of quality in the result. Finally, chapter five presents the final considerations of this thesis, where it is possible to conclude that capillary electrophoresis, even being little utilized in Brazilian forensic laboratories, can be a tool of great utility in toxicological analyses destined to this purpose.

No período de 2009 a 2014 foram selecionados do arquivo da Faculdade de Medicina Veterinária e Zootecnia, UNESP - Universidade Estadual Paulista, Campus de Botucatu, Departamento de Clínica Veterinária, Serviço de Patologia Veterinária, 42 casos, sendo 31 (73,8%) cães e 11 (26,2%) gatos. Destes casos 21 (50%) apresentaram Boletim de Ocorrência e 22 (52,4%) realizaram exame toxicológico. A maior prevalência foi de intoxicações por carbamato. O exame necroscópico revelou que a as principais causa mortis foram insuficiência cardiorrespiratória e choque hipovolêmico. No exame histopatológico de fígado, rim e encéfalo as principais lesões observadas foram congestão, degeneração e hemorragia. Os órgãos apresentaram sinais de autólise e putrefação. As técnicas diagnósticas utilizadas são complementares e auxiliam o Médico Veterinário a elaborar laudos técnicos para processos judiciais nos casos de intoxicações criminais
Abstract: The cases of poisoning no intentional or intentional are common in the history of the Veterinary Medicine mainly in animals of company as dogs and cats. The Legal Veterinary Medicine use these tools in the base of technical decisions to aid processes, involving crimes with animals. According to the Law of Environmental Crimes 9.605 of February 12 of 1998, poisoning in animals is considered crime of mistreatments. The appropriate recognition of the clinical signs, lesions anatomical pathological that characterizes the cases of intoxication that take to death associated with the methods of identification laboratorial of forensic toxicology is fundamental to establish a definitive diagnosis of the toxic agent. In the present work was made analysis of lesions relation of toxic agents and context of Veterinary Forensic Medicine in these situations. In period 2009 to 2014 are selected from the archive of Faculdade de Medicina Veterinária e Zootecnia, UNESP - Universidade Estadual Paulista, Campus de Botucatu, Departamento de Clínica Veterinária, Serviço de Patologia Veterinária 42 cases, 31 (73,8%) dogs and 11 (26,2%) cats. These cases 21 (50%) feature Boletim de Ocorrência and 22 (52,4%) are made toxicologycal exam. The highest prevalence ware intoxication for carbamate. The necropsy revealed that main causa mortis were cardiac respiratory insufficiency and hypovolemic shock. In histopathology of liver, kidney and brain the main lesions are congestion, degeneration and bledding. The organs show signs of autolysis and putrefaction. The diagnostic technics used are additional and help veterinarion to make reports for litigation in cases of criminal intoxication
