Intoxicaciones por benzodiacepinas y antidepresivos, una realidad preocupante / Epidemiological Characterization of Benzodiazepine and Antidepressant Poisonings in Chile

INTRODUCTION: Poisonings are a worldwide preventable public health problem that affects the general population. OBJECTIVE: To epidemiologically characterize BZ and AD poisonings registered in Chile between 2002 and 2019. METHODS: An observational retrospective study of poisonings registered in the medical outcome report system of the Chilean Ministry of Health was conducted. The World Health Organization International Classification of Disease codes T42.2, T43.0 and T43.2 were included. RESULTS: 22,807 poisonings associated with BZ or AD were identified, representing 0.08% of all hospitalizations. Poisoning rates distribution were established at regional and national level. There were 9.8% of accidental events, 63.7% of intentional events, and 26.5% of undetermined cases. The highest accidental and intentional poisoning rates were estimated at the ages of 0 to 4 and 15 to 19 years old respectively. Poisoned patients remained hospitalized on average for 3.4 days. 0.3% of cases were related to death of patients. CONCLUSIONS: Poisoning events were characterized according to the studied variables. National poisoning rates decreased over the years with prevalence of those intentional events linked to women. Efforts should be made in creating poisoning prevention campaigns focused on age-based groups in the general population.

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.

Cocaína adulterada con opioides en la provincia de Buenos Aires: análisis epidemiológico para pensar una nueva política de drogas / Cocaine adulterated with opioids in the province of Buenos Aires: epidemiological analysis to think about a New Drug Policy

INTRODUCCIÓN: En febrero de 2022 se produjo en la provincia de Buenos Aires un brote de intoxicación por consumo de cocaína adulterada con opioides. El objetivo de este trabajo fue describir la población afectada, las acciones realizadas desde el Ministerio de Salud de la Provincia de Buenos Aires a partir de la detección de la problemática y analizar las modalidades de abordaje de los consumos respecto de los paradigmas de atención desde la perspectiva de la salud y las normativas vigentes en la temática en Argentina. MÉTODOS: Se realizó un estudio descriptivo transversal con enfoque cuantitativo. Se estudió a todas las personas que presentaban síntomas compatibles con cuadros de intoxicación por consumo de cocaína adulterada y que consultaron en establecimientos de salud de la provincia de Buenos Aires en febrero de 2022. RESULTADOS: Se notificaron 124 casos, el rango etario fue de 18 a 57 años, y el 84,5% fueron informados como sexo legal masculino. El 66% requirió internación hospitalaria, y 19 personas fallecieron. Los resultados de laboratorio confirmaron que la sustancia consumida era cocaína con carfentanilo. DISCUSIÓN: La identificación de opioides es un fenómeno novedoso en la región, que invita a problematizar los marcos normativos y los paradigmas de abordaje vigentes para superar visiones que reducen la problemática a los aspectos inherentes a los individuos y sus conductas respecto del consumo de sustancias psicoactivas.

Intoxicação cutânea grave por Paraquat / Serious skin poisoning by Paraquat

O Paraquat é um herbicida não seletivo altamente tóxico, sendo responsável por altas taxas de letalidade acidentais ou provocadas, devido, principalmente, à insuficiência respiratória. Apesar de a intoxicação por via oral ser a principal e mais grave, o contato prolongado com a substância em uma grande área corporal pode gerar uma toxicidade similar e levar ao óbito ­ fato pouco elucidado na literatura. Este é o relato de caso de um homem de 22 anos, que foi admitido em um hospital devido a queixas de mal-estar, náuseas, febre, cefaleia, dor abdominal, diarreia, queimaduras e dispneia. A suspeita diagnóstica inicial foi de hantavirose, leptospirose, dengue e tromboembolismo pulmonar e, posteriormente, foi comprovado intoxicação exógena com agrotóxico por via inalatória e cutânea. Exames de imagem revelaram fibrose pulmonar difusa e ele também apresentou alterações renais, hepáticas e coagulatórias. Como não há antídoto específico, foi empregado tratamento sintomático e suportivo, com uso de carvão ativado, antibióticos, corticoides, antioxidantes e hemodiálise. No entanto, o paciente teve uma piora progressiva do quadro, vindo a óbito devido à síndrome da angústia respiratória aguda e fibrose pulmonar. O Paraquat, embora proibido no Brasil em 2020, continua sendo utilizado de forma ilegal. Além disso, seu substituto, o Diquat, possui toxicidade semelhante. Assim, é fundamental que os profissionais da saúde reconheçam o diagnóstico da intoxicação por tais substâncias e suas diferentes vias de exposição. Também são necessárias novas medidas de fiscalização das substâncias e maior investimento em educação em saúde para evitar exposições acidentais, assim como relatado (AU).

Paraquat is a highly toxic non-selective herbicide and is responsible for high accidental or provoked lethality rates, mainly due to respiratory failure. Although oral poisoning is the primary and most severe, prolonged contact with the substance in a large body area can lead to similar toxicity and death ­ a fact that is little elucidated in the literature. This is the case report of a 22-year-old man admitted to a hospital due to complaints of malaise, nausea, fever, headache, abdominal pain, diarrhea, burns and dyspnea. The initial diagnostic suspicion was hantaviruses, leptospirosis, dengue and pulmonary thromboembolism, and there was subsequently proven exogenous intoxication with pesticides by inhalation and cutaneous route. Imaging tests revealed diffuse pulmonary fibrosis and he also had renal, hepatic and coagulation alterations. As there is no specific antidote, symptomatic and supportive treatment was performed using activated charcoal, antibiotics, corticosteroids, antioxidants and hemodialysis. However, the patient had a progressive worsening of the condition and died due to acute respiratory distress syndrome and pulmonary fibrosis. Paraquat, although banned in Brazil in 2020, continues to be used illegally. In addition, its substitute, the Diquat, has similar toxicity. Thus, it is essential that health professionals recognize the diagnosis of intoxication by such substances and their different exposure routes. New control measures for these substances and greater investment in health education are also needed to prevent accidental exposure, as reported (AU).

Uso de agrotóxicos e mortes por câncer no estado do Rio Grande do Sul / Pesticide use and cancer deaths in Rio Grande do Sul, Brazil

Resumo Este estudo teve como objetivo caracterizar as regiões de saúde do estado do Rio Grande do Sul (RS) quanto ao uso de agrotóxicos e à mortalidade por câncer de próstata, linfoma não Hodgkin (LNH) e leucemias. Para cada região de saúde foram estimados o volume total de agrotóxicos utilizado, o volume usado por área plantada, a proporção de lavouras com uso, a proporção de agricultura familiar e o grau de desigualdade na distribuição das terras. A mortalidade pelos três tipos de câncer foi descrita com base na mortalidade proporcional e na taxa de mortalidade ajustada por idade. A associação entre as variáveis foi estimada pelo coeficiente de correlação de Spearman. A mortalidade por câncer de próstata mostrou-se relacionada à produção agrícola intensa, utilização de elevado volume de agrotóxicos e menor proporção de agricultura familiar. Já a mortalidade por linfoma não Hodgkin e leucemias esteve associada positivamente à proporção de agricultura familiar. Mortalidade proporcional e taxa de mortalidade ajustada por idade mostraram-se positivamente correlacionadas para os três tipos de câncer. Este estudo demonstrou que, nas regiões de saúde do RS, a mortalidade pelos três tipos de câncer investigados está vinculada, em diferentes intensidades, ao uso de agrotóxicos e a características da agricultura praticada.

Abstract This study characterizes the health regions of the Rio Grande do Sul State regarding pesticide use and mortality by prostate cancer, Non-Hodgkin's Lymphoma and leukemias. Total volume of pesticide used, volume used per planted area, the proportion of crops using pesticides, the proportion of family farming and the degree of inequality in land distribution were estimated for each region. Mortality from the three types of cancer was described by proportional mortality and age-adjusted mortality rate. Association between variables was estimated using Spearman's correlation coefficient. Prostate cancer mortality was associated with intense agricultural production, high volume of pesticide use and a lower proportion of family farming. Mortality from Non-Hodgkin's Lymphoma and leukemias, in turn, was positively associated with the proportion of family farming. Proportional mortality and age-adjusted mortality rate were positively correlated for the three types of cancer. In conclusion, in the health regions of Rio Grande do Sul, mortality by the three types of cancer investigated is associated, albeit at different intensities, with pesticide use and the type of agriculture practiced.

Intoxicación por plaguicidas en autopsias medicolegales. Tegucigalpa 2014-2020 / Poisoning by pesticides in medicolegal autopsies. Tegucigalpa 2014- 2020

Justificación: Los plaguicidas han provocado un significativo problema de salud pública ya que han generado una importante carga a la mortalidad y a la morbilidad. Los suicidios con plaguicidas representan alrededor de un tercio de todos los suicidios en el mundo. Objetivo: Caracterizar las muertes relacionadas a plaguicidas, sometidas a autopsia médico legal en la Dirección de Medicina Forense de Tegucigalpa durante los años 2014- 2020. Metodología: Se consultó la base de datos digital la Dirección de Medicina Forense, encontrando 255 casos relacionados a muerte por plaguicidas de los que se seleccionaron 215 casos con expediente completo y disponible. Los cálculos estadísticos se realizaron con el programa PSPP. Resultados: Se encontraron 215 casos, el 58% eran hombres y el 42% mujeres, 54% eran solteros y 29% en unión libre. Sin escolaridad 11%, primaria incompleta 20%, primaria completa 15%, secundaria incompleta 12%, secundaria completa 10%. Respecto a la ocupación de los fallecidos, los oficios domésticos fue la más frecuente entre las mujeres y la agricultura entre los hombres. El 65% eran personas jóvenes menores de 40 años con una media de edad de 35 años (rango 8- 89a). La manera de muerte más frecuente fue suicida con el 71%. El plaguicida más utilizado como instrumento de muerte fue el fosfuro de aluminio (66%).Conclusión: La mayoría de las muertes por intoxicación con plaguicidas fueron suicidas; hombres jóvenes, menores de 40 años, solteros, con escolaridad que no sobrepasaba la secundaria; utilizaron las pastillas de fosfuro de aluminio como instrumento de autolesión. Se requiere estudiar más detalladamente el uso de tóxicos en general y de los plaguicidas en particular como instrumentos de autolesión y se evidencia la necesidad imperiosa de habilitar medidas de regulación para la comercialización y campañas de educación en la población para el uso y manejo adecuado...(AU)

Intoxicación intencional por paracetamol en adolescentes: un problema de salud creciente: a propósito de un caso / Intentional paracetamol poisoning in adolescents: a growing health problem: clinical case study / Intoxicação intencional por paracetamol em adolescentes: um problema de saúde crescente: relato de caso

La intoxicación por paracetamol de causa no intencional en niños pequeños, e intencional en adolescentes es un motivo de consulta cada vez más frecuente en los servicios de urgencia. La gravedad y el pronóstico de esta intoxicación están dados por el riesgo de falla hepática. Ante la sospecha de ingesta de paracetamol, se debe conocer el tiempo transcurrido, la cantidad de ingesta del fármaco, estimar la toxicidad de la dosis ingerida para predecir hepatotoxicidad, determinar las medidas de contaminación necesarias, dosificar paracetamol en sangre y evaluar la necesidad de administración de antídoto. Se describe el caso de una adolescente que con intención suicida presentó una intoxicación aguda por paracetamol con riesgo de daño hepático requiriendo decontaminación digestiva, administración de antídoto y abordaje interdisciplinario de sus problemas psicoemocionales.

Paracetamol intoxication due to an unintentional cause in young children, and intentional in adolescents, is an increasingly frequent cause for consultation in emergency services. The severity and prognosis of this poisoning is due to the risk of liver failure. Given the suspicion of paracetamol ingestion, the time passed since the ingestion, the amount of paracetamol ingested, the estimate of the dose ingested to predict hepatotoxicity, we must determine the necessary decontamination measures and the paracetamol dose in blood and evaluate the need to administer a paracetamol antidote. We describe the case of an adolescent who presented acute paracetamol poisoning with risk of liver damage resulting from a suicide attempt and who required digestive decontamination, antidote administration and an interdisciplinary approach to her psychological and emotional problems.

A intoxicação não intencional por paracetamol em crianças pequenas e a intoxicação intencional em adolescentes é um motivo cada vez mais comum de consulta em serviços de emergência. A gravidade e o prognóstico desse envenenamento são dados pelo risco de insuficiência hepática. Quando há suspeita de ingestão de paracetamol, o tempo decorrido desde que é ingerido, a quantidade de paracetamol ingerida, a estimação da dose ingerida para predizer hepatotoxicidade, utilizamse para determinar as medidas de contaminação necessárias, dosar paracetamol no sangue e avaliar a ne- cessidade de administração de antídoto. Descrevemos o caso de uma adolescente com intenção suicida que apresentou intoxicação aguda por paracetamol com risco de lesão hepática com necessidade de descontaminação digestiva, administração de antídoto e abordagem interdisciplinar de seus problemas psicoemocionais.

Introducción. Las emulsiones lipídicas intravenosas (ELI) son unas emulsiones grasas no tóxicas con fosfolípidos, actualmente aprobadas para su uso en el tratamiento de intoxicaciones, específicamente en las producidas por anestésicos locales. El propósito de este estudio es la caracterización del uso de ELI en pacientes mayores de 18 años, que presentaron intoxicación por sustancias y medicamentos diferentes a anestésicos locales, en un hospital de alta complejidad de la ciudad de Medellín, durante el periodo comprendido entre 2015 y 2020. Metodología. Se realizó un estudio descriptivo, retrospectivo, de casos que recibieron ELI como tratamiento para su intoxicación. Se hizo revisión de las historias clínicas de la población objeto de estudio. Se recolectó información acerca de variables sociodemográficas, clínicas y paraclínicas, y de atención. Se hizo análisis univariado de las variables de interés. Resultados. Del total de 1.966 intoxicaciones, se incluyeron 51 (2,6 %) casos de intoxicación por sustancias y medicamentos diferentes a anestésicos locales, que recibieron la terapia con ELI entre 2015 y 2020. La mediana de edad de los participantes fue de 27 años. Un 74,5 % de los participantes presentó intoxicación por medicamentos. El promedio de la dosis de ELI recibida fue de 1.036 mL en 24 horas, dosis inferior a la calculada por kilo de peso que debían recibir, de 1.149 mL en promedio. Un 86,3 % (n=44) de los casos presentaron neurotoxicidad, y 76,5 % (n=39) presentaron cardiotoxicidad. La neurotoxicidad mejoró en el 34,7 % y la cardiotoxicidad en el 59,1 % de los individuos que recibieron terapia con ELI. Conclusión. La aplicación de las ELI se hizo en personas en su mayoría intoxicadas por antipsicóticos, hombres, jóvenes; menos de la mitad tenía compromiso de la ventilación, y hubo mejoría en la cardiotoxicidad y neurotoxicidad. Hubo una diferencia entre la dosis recibida y la que debían recibir ajustada por el peso

Introduction. Intravenous lipid emulsions (IVLE) are non-toxic fatty emulsions with phospholipids, currently approved for use in the treatment of poisoning, specifically those produced by local anesthetics. The purpose of this study is to characterize the use of IVLE in patients over 18 years of age, who presented intoxication by substances and medications other than local anesthetics, in a high complexity hospital in the city of Medellín, during the period between 2015 and 2020. Methodology. A retrospective descriptive study was carried out on cases that received IVLE as a treatment for their poisoning. The clinical records of the study population were reviewed. Information was collected about sociodemographic, clinical and paraclinical variables, and care. Univariate analysis of the variables of interest was performed. Results. Of the total of 1,966 poisonings, 51 (2.6%) cases caused by substances and medications other than local anesthetics, received ELI therapy between 2015 and 2020 and were included in the study. The median age of the participants was 27 years. 74.5% of the participants presented drug poisoning. The average IVLE dose received was 1,036 mL in 24 hours, a lower dose than the one calculated per kilo of weight, which had been on average 1,149 mL. 86.3% (n=44) of the cases presented neurotoxicity, and 76.5% (n=39) presented cardiotoxicity. Neurotoxicity improved in 34.7% and cardiotoxicity in 59.1% of individuals receiving ELI therapy. Conclusion. The application of IVLE was made in people mostly poisoned by antipsychotics, men, young people, less than half had compromised ventilation, and there was improvement in cardiotoxicity and neurotoxicity. There was a difference between the dose received and the one they should have received adjusted for weight

Clinical characteristics and follow-up analysis of 12 patients of acute phosphine poisoning / 中华劳动卫生职业病杂志

Objective: To investigate the clinical characteristics of patients with acute phosphine poisoning, and to follow up and evaluate the prognosis of patients. Methods: In May 2022, 12 patients with phosphine poisoning by respiratory inhalation in Beijing Chao-Yang Hospital of Capital Medical University were analyzed. The patients were treated with symptomatic support therapy. Three months later, patients were re-evaluated the symptoms of poisoning, pulmonary function and magnetic resonance imaging (MRI) of the brain to understand the prognosis of the phosphine poisoning. Results: The main symptoms of 12 patients were respiratory and central nervous system symptoms with hypoxia. The symptoms of poisoning improved after treatment. Follow-up found that the patients had different degrees of residual symptoms. Pulmonary function showed increased airway resistance. Airway challenge test was positive in some patients. MRI of the head of some patients showed small ischemic focus in bilateral frontal lobes. Conclusion: Acute phosphine poisoning may cause persistent damage to the respiratory system and central system, and residual symptoms after 3 months.

One case of myocardial damage caused by carbamate pesticide poisoning / 中华劳动卫生职业病杂志

The data of a patient with carbamate pesticide poisoning were analyzed. Cardiac arrest, oliguria, acute renal injury and pulmonary infection occurred during treatment. After cardiopulmonary resuscitation, tracheal intubation, CRRT, anti-infection and other symptomatic support treatment, the patient recovered and discharged. The myocardial damage caused by carbamate pesticide poisoning is easy to be ignored, and it often causes cardiac manifestations such as arrhythmia and cardiac insufficiency, and the related markers of cardiac injury, electrocardiogram and echocardiogram are also changed. Therefore, the awareness of cardiac damage caused by carbamate pesticide poisoning should be improved.

Three cases of acute chlorfenapyr poisoning / 中华劳动卫生职业病杂志

This paper reported 3 cases of poisoning caused by chlorfenagyr. Chlorfenapyr poisoning has gradually increased in clinical practice. The early stage after poisoning is digestive tract symptoms, followed by sweating, high fever, changes in consciousness, changes in myocardial enzymology, etc. Its main mechanism of intoxication is uncoupling oxidative phosphorylation. Since there is no specific antidote after poisoning, the fatality rate of chlorfenapyr poisoning remains high. The therapeutic measures are early gastrointestinal decontamination, symptomatic and supportive treatments, and early blood purification may be an effective treatment.
