Behavioral or neuropsychiatric symptoms of Alzheimer's disease: from psychopathology to pharmacological management / Sintomas comportamentais ou neuropsiquiátricos da doença de Alzheimer: psicopatologia e abordagem terapêutica

Abstract Neuropsychiatric or behavioral symptoms of dementia encompass a series of disorders, such as anxiety, depression, apathy, psychosis, and agitation, all commonly present in individuals living with dementia. While they are not required for the diagnosis of Alzheimer's disease (AD), they are ubiquitously present in all stages of the disease, contributing to negative clinical outcomes, including cognitive decline, functional disability, and caregiver burden. Neuropsychiatric symptoms have been conceptualized not only as risk factors but as clinical markers of decline along the AD spectrum. The concept of "mild behavioral impairment", the behavioral correlate of mild cognitive impairment, has been proposed within this framework. The first steps in the management of behavioral symptoms in AD involve defining the target and investigating potential causes and/or aggravating factors. Once these factors are addressed, non-pharmacological approaches are preferred as first-line interventions. Following the optimization of anticholinesterase treatments, specific pharmacological approaches (e.g., antidepressants, antipsychotics) can be considered weighing potential side effects.

Resumo Sintomas neuropsiquiátricos ou comportamentais de demência envolvem uma série de condições, como ansiedade, depressão, apatia, psicose e agitação, frequentemente observadas em indivíduos com demência. Embora esses sintomas não sejam necessários para o diagnóstico da doença de Alzheimer, estão presentes em todas as fases ou estágios da doença, contribuindo negativamente para o declínio cognitivo, comprometimento funcional e sobrecarga do cuidador. Os sintomas neuropsiquiátricos têm sido conceituados não apenas como fatores de risco, mas também como marcadores clínicos de progressão da doença de Alzheimer. O construto "comprometimento comportamental leve", correlato comportamental do comprometimento cognitive leve, tem sido proposto nesse contexto. Os primeiros passos na abordagem dos sintomas comportamentais da doença de Alzheimer envolvem definir os alvos-terapêuticos e investigar potenciais causas ou fatores agravantes. Após intervir nesses fatores, abordagens não farmacológicas constituem a primeira linha de intervenção. Depois da otimização do tratamento anticolinesterásico, terapias farmacológicas específicas (por exemplo, antidepressivos, antipsicóticos) podem ser consideradas, levando-se em conta potencias efeitos colaterais.

Translation, cross-cultural adaptation, and validation of the Behavioral Activity Rating Scale (BARS) for the Brazilian population

Abstract Introduction Few instruments are available in Brazil to evaluate psychomotor activity in psychiatric emergency, clinical, and research settings. This study aimed to perform a cross-cultural adaptation of the Behavioral Activity Rating Scale (BARS) into Brazilian Portuguese and assess the adapted scale's psychometric properties. Method An expert consensus committee conducted a translation and back-translation of the original scale, resulting in the BARS-BR. Four pairs of physicians administered the BARS-BR and the Sedation-Agitation Scale (SAS) to patients in a hospital psychiatry emergency room and patients in the hospital's psychiatric wards. The BARS-BR was compared to the SAS to assess concurrent validity and internal consistency was evaluated with the Bland-Altman technique. Results In the emergency room, the correlation coefficients between the first and second assessments were rho = 0.997 and rho = 1.0, respectively. In the hospital wards, the correlation coefficient between the pair of evaluators was rho = 0.951. There were strong correlations between the BARS-BR score of the first examiner and the SAS score of the second examiner (rho = 0.903) and between the SAS score of the first examiner and the BARS-BR score of the second examiner (rho = 0.893). Conclusion The BARS-BR showed good psychometric properties, and we recommend its use because it constitutes an easy method for assessment of changes in psychomotor activity. Further studies are suggested to evaluate adoption and comprehension of the BARS-BR scale by all classes of healthcare professionals.

Background: Neuropsychiatric symptoms can be part of the clinical spectrum of COVID-19 infections. Aim: To devise an evidence based clinical algorithm as a guide for clinicians, to identify and treat underlying clinical syndromes of psychomotor agitation, such as delirium, catatonia or substance withdrawal in patients who are hospitalized and infected with SARS-CoV-2. Material and Methods: A review of the literature about the pharmacological management of neuropsychiatric manifestations of COVID-19 at the general hospital, to develop a clinical protocol based on a consensus from an interdisciplinary expert panel at a Clinical Hospital. Results: A consensual clinical algorithm for the management of delirium, catatonia, and substance withdrawal, manifested as psychomotor agitation in patients hospitalized with COVID-19, was developed as a clinical proposal for physicians at different levels of complexity in health services. Conclusions: Cooperation among different clinical units in the general hospital facilitated the implementation of a clinical algorithm for clinicians for the management of psychomotor agitation in COVID-19 patients.

Guía práctica para el manejo de la agitación psicomotora en pediatría / Clinical Guide for the management of psychomotor agitation in pediatrics

La agitación psicomotora es un estado de hiperactividad impulsiva aguda en grados variables, que requiere intervención. Sus manifestaciones abarcan un amplio espectro desde mínima inquietud hasta perturbaciones intensas con grandes movimientos no propositivos o violentos. Datos recientes muestran que aproximadamente 10-20% de los niños, niñas y adolescentes (NNA) presenta una patología de la esfera psiquiátrica y/o abuso de sustancias y, en consecuencia, han aumentado las consultas por estos motivos en servicios de urgencia pediátrica. Hasta 1 de cada 15 NNA requiere contención de algún tipo. Las causas de agitación son múltiples y se deben investigar en cada paciente. El objetivo de este trabajo es concientizar al equipo de salud sobre el problema y contribuir a la estandarización del manejo clínico en pediatría. Se describen intervenciones no farmacológicas, contención farmacológica y física, con sus respectivas indicaciones.

Psychomotor agitation is a state of acute impulsive hyperactivity with varying degrees of magnitude that requires intervention. Its manifestations cover a broad spectrum from minimal unrest to intense disturbances with large non-purposeful or violent movements. Recent data show that approximately 10-20% of children and adolescents have a psychiatric disease and/or substance abuse disorder and, consequently, consultations for these reasons have increased in pediatric emergency services. Up to 1 in 15 children require some form of restraint. Causes of agitation are multiple and must be investigated in each patient. The objectives of this review are to improve awareness of the issue to health work-teams and aims at the standardization of its medical management in pediatrics. Non-pharmacological interventions, chemical and physical restraint methods are described, with their respective indications.

Assessment of delirium in children admitted into the Intensive Care Unit: psCAM-ICU Tool

Abstract Background: Delirium has been identified as a risk factor for the mortality of critically ill patients, generating great social and economic impacts, since patients require more days of mechanical ventilation and a prolonged hospital stay in the intensive care unit (ICU), thus increasing medical costs. Objective: To describe the prevalence and characteristics of delirium episodes in a sample of 6-month to 5-year-old children who are critically ill. Methods: Cohort study at a Pediatric Intensive Care Unit (PICU) in Bogotá (Colombia). Participants were assessed by the Preschool Confusion Assessment Method for the ICU (psCAM-lCU) within the first twenty-four hours of hospitalization. Results: One quarter of the participants (25.8%) presented some type of delirium. Among them, two sub-types of delirium were observed: 62.5% of the cases were hypoactive and 37.5% hyperactive. Moreover, from them, six were male (75%) and 2 female (25%). Primary diagnosis was respiratory tract infection in 62.55% of the patients, while respiratory failure was diagnosed in the remaining 37.5%. Conclusions: The implementation of delirium monitoring tools in critically ill children provides a better understanding of the clinical manifestation of this phenomenon and associated risk factors in order to contribute to the design of efficient intervention strategies.

Resumen Introducción: el delirium se ha identificado como un factor de riesgo para la mortalidad de pacientes en estado crítico, lo que genera un mayor impacto social y económico, teniendo en cuenta que los pacientes requieren más días de ventilación mecánica y una estancia hospitalaria prolongada en la unidad de cuidados intensivos (UCI), lo que incrementa los costos médicos de su estadía. Objetivo: describir la prevalencia y las características de los episodios de delirium en una muestra de niños de seis meses a cinco años en estado crítico. Métodos: estudio de cohorte en una Unidad de Cuidados Intensivos Pediátricos (UCIP) en Bogotá (Colombia). Los participantes fueron evaluados por el método de evaluación de confusión preescolar para la UCI (psCAM-UCI) dentro de las 24 horas iniciales del período de hospitalización. Resultados: una cuarta parte de los participantes (25,8 %) presentó algún tipo de delirium. Entre ellos, se observaron dos subtipos de delirium: el 62,5 % de los casos era hipoactivo y el 37,5 % hiperactivo. Además, el 75% (6) de los participantes delirantes eran hombres y el 25 % (2) mujeres. En 62,5 % de los pacientes el diagnóstico primario fue infección de las vías respiratorias, mientras que la insuficiencia respiratoria fue diagnosticada en el 37,5 % restante. Conclusiones: la implementación de herramientas de monitoreo del delirium con niños en estado crítico proporciona una mejor comprensión de la presentación clínica de este fenómeno y los factores de riesgo asociados, con lo cual es posible contribuir al diseño de estrategias de intervención eficientes.

Resumo Introdução: o delirium foi identificado como um fator de risco para a mortalidade de pacientes graves, o que gera maior impacto social e econômico, visto que os pacientes necessitam de mais dias de ventilação mecânica e internação prolongada na unidade de terapia intensiva (UTI), o que aumenta os custos médicos para a sua estadia. Objetivo: descrever a prevalência e as características dos episódios de delirium em uma amostra de crianças de 6 meses a 5 anos, gravemente doentes. Métodos: estudo de coorte em uma Unidade de Terapia Intensiva Pediátrica (UTIP) em Bogotá (Colômbia). Os participantes foram avaliados pelo método de avaliação de confusão pré-escolar para a UTI (psCAM-UTl) dentro das primeiras 24 horas do período de internação. Resultados: um quarto dos participantes (25,8%) apresentou algum tipo de delirium. Entre eles, dois subtipos de delirium foram observados: 62,5% dos casos eram hipoativos e 37,5% hiperativos. Além disso, 75% (6) dos participantes delirantes eram do sexo masculino e 25% (2) feminino. Em 62,5 % dos pacientes, o diagnóstico primário foi infecção das vias respiratórias, enquanto a insuficiência respiratória foi diagnosticada em 37,5 % restante. Conclusões: a implementação de instrumentos de monitorização do delirium com crianças gravemente doentes permite uma melhor compreensão da apresentação clínica do fenômeno e dos fatores de risco associados, de forma a contribuir para o desenho de estratégias de intervenção eficazes.

Intervenções não farmacológicas de manejo na agitação de idosos com demência em ambiente doméstico / Intervenciones no farmacológicas de manejo de la agitación en ancianos con demencia en ambiente doméstico / Nonpharmacological Interventions for Managing Agitation in Elderlies with Dementia in the Home Setting

Introdução: A agitação é um sintoma neuropsiquiátrico recorrente em idosos com demência. No ambiente doméstico, essa condição impõe aos familiares cuidadores o desafio de intervir adequada e precocemente a fim de minimizar visitas às emergências, internações ou até mesmo institucionalizações de longa permanência. Objetivo: Identificar as intervenções não farmacológicas utilizadas por familiares cuidadores no manejo da agitação em idosos com demência. Métodos: Pesquisa qualitativa realizada com 11 familiares cuidadores de idosos em Minas Gerais, Brasil. Foram realizadas entrevistas com roteiro semiestruturado e, para a análise, foi empregada a técnica de análise de conteúdo. Resultados: As intervenções mais utilizadas foram: a conversa, a escuta, a distração, o uso de brinquedos, a música/canto e a leitura da Bíblia para acessar a espiritualidade/religiosidade. Verificou-se que, diante dos desafios impostos pela demência ao cuidado e dos desgastes físico e emocional experimentados, os familiares esforçaram-se para acolher e oferecer suporte humano ao idoso, além de sentirem-se satisfeitos por terem a oportunidade de retribuir o cuidado que receberam. Conclusão: Não há uma intervenção capaz de responder a todos os comportamentos agitados. A experiência e o vínculo desenvolvido entre familiares cuidadores e idosos ajudaram a guiar a escolha individual de intervenções não farmacológicas mais eficazes, provavelmente, por facultar certa antecipação das respostas dos idosos(AU)

Introducción: La agitación es un síntoma neuropsiquiátrico recurrente en ancianos con demencia. En el cotidiano del ambiente doméstico, esta condición impone a los familiares cuidadores el desafío de encontrar estrategias adecuadas de manejo a fin de evitar las visitas a emergencias, hospitalizaciones o incluso la institucionalización a largo plazo. Objetivo: Identificar las estrategias no farmacológicas utilizadas por los familiares cuidadores en el manejo de la agitación en ancianos con demencia. Métodos: Investigación cualitativa realizada con 11 familiares cuidadores de ancianos en Minas Gerais, Brasil. La recolección de datos fue realizada a través de entrevistas con guión semiestructurado. Para la interpretación de los datos se utilizó la técnica de análisis de contenido. Resultados: Se identificaron como estrategias más utilizadas para el manejo de la agitación: la conversación, la escucha, la distracción, el uso de juguetes, la música/canto y la lectura de la Biblia para acceder a la espiritualidad/religiosidad. Se verificó que, frente a los desafíos impuestos por la demencia al cuidado y el desgaste físico y emocional experimentado, los familiares cuidadores se esforzaron para acoger y brindar apoyo humano al familiar anciano, además de sentirse satisfechos por tener la oportunidad de retribuir el cuidado que recibieron. Conclusiones: No hay una intervención capaz de responder efectivamente a todos los comportamientos agitados. Sin embargo, la experiencia y el vínculo desarrollado entre familiares cuidadores y ancianos guiaron la elección individual de las intervenciones no farmacológicas más efectivas, probablemente al proporcionar cierta anticipación de las respuestas de los ancianos(AU)

Introduction: Agitation is a neuropsychiatric symptom recurrent in elderly people with dementia. In the daily life of the home setting, this condition imposes on the family caregivers the challenge of finding appropriate management strategies for avoiding visits to the emergency room, hospitalizations, or even long-term institutionalization. Objective: To identify the nonpharmacological strategies used by family caregivers in the management of agitation in elderly people with dementia. Methods: Qualitative research carried out with 11 family caregivers of elderly people in Minas Gerais, Brazil. The data collection was carried out through interviews with semi-structured repertory of quotations. The content analysis technique was used to interpret the data. Results: The most commonly used strategies for agitation management were identified. These were conversation, listening, distraction, use of toys, music/singing, and reading the Bible for accessing spirituality or religiosity. It was verified that, in the face of the challenges imposed by dementia onto the care and the physical and emotional outwearing experienced, family caregivers strived to welcome and provide human support to the elderly relative, in addition to feeling satisfied to have the opportunity to give back the care received Conclusions: There is no intervention capable of responding effectively to all agitation-related behaviors. However, the experience and the relationship developed between family caregivers and the elderly guided the individual choice for the most effective nonpharmacological interventions, probably by providing some anticipation to the elderly's responses(AU)

Brazilian guidelines for the management of psychomotor agitation. Part 2. Pharmacological approach

Objective: To present the essential guidelines for pharmacological management of patients with psychomotor agitation in Brazil. Methods: This is a systematic review of articles retrieved from the MEDLINE (PubMed), Cochrane Database of Systematic Reviews, and SciELO databases published from 1997 to 2017. Other relevant articles in the literature were also used to develop these guidelines. The search strategy used structured questions formulated using the PICO model, as recommended by the Guidelines Project of the Brazilian Medical Association. Recommendations were summarized according to their level of evidence, which was determined using the Oxford Centre for Evidence-based Medicine system and critical appraisal tools. Results: Of 5,362 articles retrieved, 1,731 abstracts were selected for further reading. The final sample included 74 articles that met all inclusion criteria. The evidence shows that pharmacologic treatment is indicated only after non-pharmacologic approaches have failed. The cause of the agitation, side effects of the medications, and contraindications must guide the medication choice. The oral route should be preferred for drug administration; IV administration must be avoided. All subjects must be monitored before and after medication administration. Conclusion: If non-pharmacological strategies fail, medications are needed to control agitation and violent behavior. Once medicated, the patient should be monitored until a tranquil state is possible without excessive sedation. Systematic review registry number: CRD42017054440.

Brazilian guidelines for the management of psychomotor agitation. Part 1. Non-pharmacological approach

Objective: To present the essential guidelines for non-pharmacological management of patients with psychomotor agitation in Brazil. Methods: These guidelines were developed based on a systematic review of articles published from 1997 to 2017, retrieved from MEDLINE (PubMed), Cochrane Database of Systematic Review, and SciELO. Other relevant articles identified by searching the reference lists of included studies were also used to develop these guidelines. The search strategy used structured questions formulated using the PICO model, as recommended by the Guidelines Project of the Brazilian Medical Association. Recommendations were summarized according to their level of evidence, which was determined using the Oxford Centre for Evidence-based Medicine system and critical appraisal tools. Results: We initially selected 1,731 abstracts among 5,362 articles. The final sample included 104 articles that fulfilled all the inclusion criteria. The management of agitated patients should always start with the least coercive approach. The initial non-pharmacological measures include a verbal strategy and referral of the patient to the appropriate setting, preferably a facility designed for the care of psychiatric patients with controlled noise, lighting, and safety aspects. Verbal de-escalation techniques have been shown to decrease agitation and reduce the potential for associated violence in the emergency setting. The possibility of underlying medical etiologies must be considered first and foremost. Particular attention should be paid to the patient's appearance and behavior, physical signs, and mental state. If agitation is severe, rapid tranquilization with medications is recommended. Finally, if verbal measures fail to contain the patient, physical restraint should be performed as the ultimate measure for patient protection, and always be accompanied by rapid tranquilization. Healthcare teams must be thoroughly trained to use these techniques and overcome difficulties if the verbal approach fails. It is important that healthcare professionals be trained in non-pharmacological management of patients with psychomotor agitation as part of the requirements for a degree and graduate degree. Conclusion: The non-pharmacological management of agitated patients should follow the hierarchy of less invasive to more invasive and coercive measures, starting with referral of the patient to an appropriate environment, management by a trained team, use of verbal techniques, performance of physical and mental assessment, use of medications, and, if unavoidable, use of the mechanical restraint. Systematic review registry number: CRD42017054440.

Effects of Aromatherapy on Agitation in Patients with Dementia: A Systematic Literature Review and Meta-analysis

PURPOSE: The purpose of this study is to identify the effects of aromatherapy on agitation in patients with dementia using a meta-analysis and systemic literature review. METHODS: The EMBASE, CINAHL, MEDLINE, and other databases were searched up to November 2017. RESULTS: Of 419 publications identified, 12 met inclusion criteria, and 9 studies were used to estimate the effect size of aromatherapy. A total of 837 participants across all studies were included. The commonly applied methods were massage (50%), type of oil lavender (75%), and instrument Cohen-Mansfield Agitation Inventory (75%). A medium effect size of aromatherapy on agitation was identified (d=−0.56, I2=65.0%, p=.001). The massage group has lower effect size than the other group (d=−0.98, I2=0.0%, p=.001). CONCLUSION: Aromatherapy appears to be effective in improving agitation in patients with dementia. However, further studies for home-dwelling patients with dementia and with different types of aroma oil should be conducted in the future. In addition, research with well-designed are needed to assess the effects or aromatherapy on agitation.

Manejo de la excitación psicomotriz en niños y adolescentes / Management of psychomotor excitement in children and adolescents

La agitación o excitación psicomotriz (EPM) es un síndrome que no constituye en sí mismo una enfermedad, sino que se trata de una manifestación de una gran variedad de trastornos psiquiátricos y orgánicos. Se caracteriza por aumento desorganizado de la motricidad acompañado de una activación vegetativa (sudoración, taquicardia, midriasis) y ansiedad severa. Constituye uno de los cuadros de presentación más frecuente en salas de urgencia psiquiátricas y generales. El objetivo del presente artículo es revisar los aspectos clínicos del síndrome, describir las diferentes causas y plantear su manejo en los diferentes ámbitos de la práctica clínica y medidas de seguridad. Se consideran las medidas terapéuticas no farmacológicas (intervenciones verbales, sujeción física) y medicamentosas, mencionando las vías de administración, las opciones de drogas y sus dosis según la presunción diagnóstica. Es una urgencia donde se debe actuar con rapidez para garantizar la seguridad del paciente y del entorno (AU)

Psychomotor agitation or excitation (PMA) is not a disorder in itself but a manifestation of a broad variety of psychiatric and organic disorders. It is characterized by increased disorganization of motor activity associated with vegetative activation (sweating, increased heart rate, mydriasis) and severe anxiety. It is one of the most common disorders presenting in general and psychiatric emergency departments. The aim of this study was to review the clinical aspects of the entity, to describe possible causes, and to evaluate management in different settings of clinical practice as well as safety measures. Non-pharmacological interventions (verbal interventions, physical restraint) and medications are considered, describing routes of administration, options of drugs and drug doses according to the presumed diagnosis. PMA is an urgency in which fast intervention is warranted for the safety of the patient and their environment (AU)

Effect of dexmedetomidine in children undergoing general anesthesia with sevoflurane: a meta-analysis / Efeito da dexmedetomidina em crianças submetidas à anestesia geral com sevoflurano

Abstract Background and objectives: Sevoflurane is often used in pediatric anesthesia and is associated with high incidence of psychomotor agitation. In such cases, dexmedetomidine (DEX) has been used, but its benefit and implications remain uncertain. We assessed the effects of DEX on agitation in children undergoing general anesthesia with sevoflurane. Method: Meta-analysis of randomized clinical and double-blind studies, with children undergoing elective procedures under general anesthesia with sevoflurane, using DEX or placebo. We sought articles in English in PubMed database using the following terms: Dexmedetomidine, sevoflurane (Methyl Ethers/sevoflurante), and agitation (Psychomotor Agitation). Duplicate articles with children who received premedication and used active control were excluded. It was adopted random effects model with DerSimonian-Laird testing and odds ratio (OR) calculation for dichotomous variables, and standardized mean difference for continuous variables, with their respective 95% confidence interval (CI). Results: Of 146 studies identified, 10 were selected totaling 558 patients (282 in DEX group and 276 controls). The use of DEX was considered a protective factor for psychomotor agitation (OR = 0.17; 95% CI 0.13-0.23; p < 0.0001) and nausea and vomiting in PACU (OR = 0.49; 95% CI 0.35-0.68; p < 0.0001). Wake-up time and PACU discharge time were higher in the dexmedetomidine group. There was no difference between groups for extubation time and duration of anesthesia. Conclusion: Dexmedetomidine reduces psychomotor agitation during wake-up time of children undergoing general anesthesia with sevoflurane.

Resumo Justificativa e objetivos: Sevoflurano é frequentemente usado em anestesia pediátrica e está associado à alta incidência de agitação psicomotora ao despertar. Nesses casos a dexmedetomidina (dex) tem sido usada, porém permanecem incertos seus benefícios e suas implicações. Foram avaliados os efeitos da dex sobre a agitação no despertar de crianças submetidas à anestesia geral com sevoflurano. Método: Metanálise de ensaios clínicos randomizados e duplamente encobertos, com crianças submetidas a procedimentos eletivos sob anestesia geral com sevoflurano, que usaram dex ou placebo. Buscaram-se artigos em língua inglesa na base de dados Pubmed com termos como Dexmedetomidine, sevoflurane (Methyl Ethers/sevoflurane) e agitation (Psychomotor Agitation). Artigos duplicados, com crianças que receberam medicação pré-anestésica e que usaram controle ativo foram excluídos. Adotou-se modelo de efeitos aleatórios com testes de DerSimonian-Laird e cálculo de odds ratio (OR) para variáveis dicotômicas e diferença de média padronizada para variáveis contínuas, com seus respectivos intervalos de confiança de 95% (IC). Resultados: Dos 146 estudos identificados, 10 foram selecionados, com 558 pacientes (282 no grupo dex e 276 controles). O uso da dex foi considerado fator de proteção para agitação psicomotora (OR = 0,17; 95% IC 0,13-0,23; p < 0,0001) e para náuseas e vômitos na SRPA (OR = 0,49; 95% IC 0,35-0,68; p < 0,0001). Tempo para despertar e para alta da SRPA foram maiores no grupo dexmedetomidina. Não houve diferença entre os grupos para tempo de extubação e duração da anestesia. Conclusão: A dexmedetomidina reduz a agitação psicomotora no despertar de crianças submetidas à anestesia geral com sevoflurano.

Syndrome of inappropriate antidiuretic hormone secretion induced by the phytotherapy Harpagophytum procumbers: case report / Síndrome da secreção inapropriada do hormônio antidiurético induzida pelo fitoterápico Harpagophytum procumbers: relato de caso

Abstract Introduction: The syndrome of inappropriate antidiuretic hormone secretion (SIADH) is the inability of antidiuretic hormone (ADH) suppression, compromising the mechanisms of water excretion and urinary concentration. It manifests as hyponatremia and its symptoms, especially neurological. There are many causes that trigger such disease, notably: central nervous system disorders, malignant neoplasm, drugs and others. Case Report: A 65 years female hypertensive patient presented clinical and laboratory manifestations of hyponatremia due to SIADH. It happened twice under use of herbal medication for osteoarthritis treatment. Discussion: The drug-related hyponatremia can be triggered by direct effect of the drug or by association with SIADH. The clinical manifestations presented could have been related to psychiatric condition and may have severe outcome if not properly diagnosed. The association of an herbal medicine to SIADH could be confirmed after a new episode of hyponatremia related to Harpagophytum procumbers reintroduction. Our literature review did not find this herbal medicine associated with SIADH, so far. Conclusion: SIADH may be caused by herbal medicine described from now on their association in the literature.

Resumo Introdução: A síndrome da secreção inapropriada do hormônio antidiurético (SIADH) consiste na incapacidade de supressão do hormônio antidiurético (ADH), comprometendo os mecanismos de excreção da água e concentração urinária. Possui como manifestações a hiponatremia e seus sintomas, sobretudo neurológicos. Há variadas causas que desencadeiam tal distúrbio, a se destacarem: distúrbios do sistema nervoso central, neoplasias malignas e drogas, dentre outros. Relato de Caso: Paciente feminina, 65 anos, hipertensa, apresentando manifestações clínicas e laboratoriais correspondentes à hiponatremia. O fato ocorreu em duas ocasiões em vigência de medicação fitoterápica para tratamento de osteoartrite. Discussão: A hiponatremia relacionada às drogas pode ser provocada pelo efeito direto do medicamento ou por desencadear SIADH. As manifestações clínicas apresentadas poderiam ter sido atribuídas a um quadro psiquiátrico, o que poderia ter desfecho grave, caso não diagnosticada corretamente. A associação de um fitoterápico à SIADH pôde ser confirmada após novo episódio de hiponatremia relacionado à reintrodução do Harpagophytum procumbers. Nossa revisão da literatura não encontrou este fitoterápico associado à SIADH, até o momento. Conclusão: SIADH pode ser ocasionada por medicamento fitoterápico doravante descrita sua associação na literatura.

Fatores de risco para desenvolvimento de agitação em pacientes críticos / Risk factors for agitation in critically ill patients

RESUMO Objetivo: Avaliar a incidência de agitação nos primeiros 7 dias após admissão à unidade de terapia intensiva, seus fatores de risco e associação com desfechos clínicos. Métodos: Estudo de coorte unicêntrico prospectivo que incluiu maiores 18 anos, admitidos à unidade de terapia intensiva há menos de 24 horas e com previsão de permanência superior a 48 horas. Agitação psicomotora foi definida como pontuação igual ou superior a +2 na Escala de Agitação e Sedação de Richmond ou episódio de agitação, ou registro de uso de medicação específica na ficha clínica. Resultados: Ocorreu agitação em 31,8% dos 113 pacientes incluídos. Na análise multivariada, delirium (OR = 24,14; IC95% 5,15 - 113,14; p < 0,001), dor moderada ou intensa (OR = 5,74; IC95% 1,73 - 19,10; p = 0,004), ventilação mecânica (OR = 10,14; IC95% 2,93 - 35,10; p < 0,001) e tabagismo (OR = 4,49; IC95% 1,33 - 15,17; p = 0,015) foram independentemente associados a maior risco de desenvolver de agitação. Por outro lado, hiperlactatemia associou-se a um menor risco de ocorrência de agitação (OR = 0,169; IC95% 0,04 - 0,77; p = 0,021). Pacientes agitados tiveram menor tempo livre de ventilação mecânica em 7 dias (p = 0,003). Conclusão: A incidência de agitação nos 7 primeiros dias de internação em unidade de terapia intensiva foi elevada. Delirium, dor moderada ou intensa, ventilação mecânica e tabagismo foram fatores de risco independentes para o desenvolvimento de agitação. Pacientes agitados tiveram menor tempo livre de ventilação mecânica nos 7 primeiros dias.

ABSTRACT Objective: To evaluate the incidence of agitation in the first 7 days after intensive care unit admission, its risk factors and its associations with clinical outcomes. Methods: This single-center prospective cohort study included all patients older than 18 years with a predicted stay > 48 hours within the first 24 hours of intensive care unit admission. Agitation was defined as a Richmond Agitation Sedation Scale score ≥ +2, an episode of agitation or the use of a specific medication recorded in patient charts. Results: Agitation occurred in 31.8% of the 113 patients. Multivariate analysis showed that delirium [OR = 24.14; CI95% 5.15 - 113.14; p < 0.001], moderate or severe pain [OR = 5.74; CI95% 1.73 - 19.10; p = 0.004], mechanical ventilation [OR = 10.14; CI95% 2.93 - 35.10; p < 0.001], and smoking habits [OR = 4.49; CI95% 1.33 - 15.17; p = 0.015] were independent factors for agitation, while hyperlactatemia was associated with a lower risk [OR = 0.169; CI95% 0.04 - 0.77; p = 0.021]. Agitated patients had fewer mechanical ventilation-free days at day 7 (p = 0.003). Conclusion: The incidence of agitation in the first 7 days after admission to the intensive care unit was high. Delirium, moderate/severe pain, mechanical ventilation, and smoking habits were independent risk factors. Agitated patients had fewer ventilator-free days in the first 7 days.

Contenção física no hospital psiquiátrico: estudo transversal das práticas e fatores de risco / Physical restraint in a Brazilian psychiatric hospital: cross-sectional study of practice and risk factors

RESUMO Objetivos Descrever a utilização da contenção física em um hospital psiquiátrico público e analisar os fatores de risco associados com seu uso, no contexto da implantação de um protocolo clínico. Métodos Em um hospital psiquiátrico público de Belo Horizonte-MG, os formulários de registro e monitoramento de contenção física (2011-2012) foram analisados e comparados com os registros das demais internações englobadas no mesmo período. Neste estudo transversal, além das análises descritivas das características clínicas e demográficas dos pacientes contidos, das técnicas utilizadas e das complicações reportadas, os fatores de risco associados com o uso da contenção foram analisados por meio de regressão logística múltipla. Resultados A contenção foi utilizada em 13,4% das internações, sendo mais comum em pacientes jovens, do sexo masculino, portadores de psicoses não orgânicas, apresentando agitação/agressividade. A técnica foi geralmente de quatro pontos, durando entre 61-240 minutos. Os únicos fatores de risco significativos para o uso da contenção incluíram a idade (OR = 0,98; p = 0,008) e o tempo de permanência (OR = 1,01; p < 0,001). Conclusões A contenção física foi utilizada usualmente na abordagem aguda do paciente agitado/agressivo inabordável verbalmente, no contexto de um transtorno psicótico. O registro dos dados vitais e dos efeitos adversos foram os itens menos aderentes aos protocolos vigentes.

ABSTRACT Objectives To describe the use of physical restraint in a public psychiatric hospital and analyze the risk factors associated with its use in the context of the implementation of a clinical protocol. Methods In a public psychiatric hospital of Belo Horizonte-MG, registration forms for monitoring physical restraint (2011-2012) were analyzed and compared with the records of other admissions in the same period. In this cross-sectional study, the clinical and demographic characteristics of the restrained patients, the techniques used and the reported complications were described. Also, risk factors associated with the use of physical restraints were analyzed using multiple logistic regression. Results Physical restraint was used in 13.4% of admissions, was more common in young male patients, with a non-organic psychoses diagnosis, presenting agitation/aggressive behavior. Usually, a four-points restraint technique was performed, lasting between 61-240 minutes. The only significant risk factors for the use of restraints included age (OR = 0.98, p = 0.008) and length of stay (OR = 1.01, p < 0.001). Conclusions Physical restraint was used in the approach of the acutely agitated, aggressive, and non-responsive to verbal de-escalation patient, in the context of a psychotic disorder. The registration of vital signs and adverse effects were the items less frequently compliant to current protocols.

Farmacoterapia de la acatisia aguda inducida por neurolépticos / Pharmacological treatment of neuroleptic-induced akathisia

La acatisia aguda es un trastorno del movimiento bastante molesto, caracterizado por sensación subjetiva y signos objetivos de inquietud motora, que se presenta frecuentemente como efecto adverso de los neurolépticos; un tratamiento oportuno es necesario para garantizar una buena adherencia al manejo con antipsicóticos y prevenir recaídas. Se describe el estado actual de los tratamientos disponibles para la acatisia aguda inducida por neurolépticos, valorando efectividad y tolerabilidad. Se realizó una búsqueda electrónica en Pubmed, Science Alert, Springer link, SciELO, Ovid y Elsevier con criterios de selección específicos, obteniendo 87 estudios, de los cuales se escogieron 51 teniendo en cuenta relevancia clínica, nivel de evidencia y actualidad. En este artículo se describen los resultados de la búsqueda. Las benzodiacepinas, los betabloqueadores lipofílicos de acción central y los anticolinérgicos son los fármacos más estudiados para el tratamiento de este trastorno del movimiento; los dos primeros han mostrado superioridad, sin embargo, se necesita aún bastante investigación al respecto.

Acute Akathisia is a movement disorder rather annoying; characterized by subjective feelings and objective signs of restlessness, which often presents as a side effect of neuroleptics, early treatment is necessary to ensure good adherence to treatment with antipsychotics and prevent relapses. To describe the state of the art of available treatments for neuroleptic-induced acute akathisia, taking into account effectiveness and tolerability. An electronic search in Pubmed, Science Alert, Springer link, SciELO, Ovid and Elsevier with specific eligibility criteria, obtaining 87 studies, of which were chosen 51 of them manually, according to their clinical relevance, topicality and level of evidence. In this paper, we describe the results of the search. The benzodiazepines, centrally acting lipophilic beta-blockers and anticholinergics, are the most studied drugs to treat this movement disorder, the first two have shown superiority; however, considerable research is still needed in this regard.

Effects of dexmedetomidine combined with subanesthetic dose of ketamine on emergence agitation in patients undergoing thoracotomy / 中华麻醉学杂志

Objective To evaluate the effects of dexmedetomidine combined with subanesthetic dose of ketamine on the emergence agitation in the patients undergoing thoracotomy.Methods Eighty ASA physical status Ⅱ or Ⅲ patients,aged 55-75 yr,weighing 50-75 kg,scheduled for elective esophageal cancer resection,were randomly divided into 4 groups (n =20 each) using a random number table:normal saline group (NS group),dexmedetomidine group (group D),subanesthetic dose of ketamine group (group K),and dexmedetomidine combined with ketamine group (group DK).In DK and K groups,ketamine 0.5 mg/kg was injected intravenously (within 1 min) at 10 min before the end of the operation.In DK and D groups,dexmedetomidine 0.5 μg/kg was infused intravenously over 10 min starting from 10 min before the end of operation.In group NS,the equal volume of normal saline was infused intravenously over 10 min starting from l0 min before the end of operation.The emergence time,extubation time,duration of ICU stay,occurrence and degree of agitation,and development of cardiovascular events and hypoxemia within 24 h after operation were recorded.Ramsay sedation scores were recorded before induction of anesthesia (T1),immediately after completion of administration at the end of surgery (T2),and at 0,5,10 and 30 min after extubation (T3-6).Results There was no significant difference in the emergence time,extubation time,and duration of ICU stay between the four groups.Compared with group NS,Ramsay sedation scores were significantly increased at T3-6,the incidence and degree of agitation were decreased,and the incidence of cardiovascular events and hyoxemia was decreased in D,K and DK groups.Compared with D or K group,Ramsay sedation scores were significantly increased at T3-6,the incidence and degree of agitation were decreased,and the incidence of cardiovascular events and hyoxemia was decreased in group DK.Conclusion Dexmedetomidine combined with subanesthetic dose of ketamine can prevent the emergence agitation in the patients undergoing thoracotomy,which provides better efficacy than either alone.

Hematological Alterations Induced by Tityus discrepans Scorpion Venom in Mice / Alteraciones Hematológicas Inducidas por el Veneno del Escorpión Tityus discrepans en Ratones

In order to evidence the hematological changes induced by the venom of the scorpion Tityus discrepans, a sublethal dose of Tityus discrepans venom (Tdv, 1 µg/g) in a total volume of 0.1 mL was intraperitoneally injected in BALB/c female mice (20±2 g; n=20). Mice were anesthetized and blood samples were withdrawn by cardiocentesis at 0 h, 3 h, 6 h, and 12 h after Tdv administration. Hematologic analyses were performed by routine procedures. A significant (p<0.05) increase in hematocrit, hemoglobin concentration and total protein concentration was observed at 3 h and 6 h, possibly due to dehydration, splenic contraction and acute-phase protein induction. The red blood cell count in envenomed mice was significantly (p<0.05) higher in comparison with the control only at 12 h. Tityus discrepans venom caused neutrophilia and lymphopenia probably as a result of catecholamine release, without significant (p>0.05) changes in absolute leukocyte count. Neither platelets number nor hematimetric indexes significantly (p>0.05) changed. Altogether, these results suggest that Tdv administration induces alterations in the hematologic profile in mice.

Para evidenciar los cambios hematológicos inducidos por la inyección intraperitoneal de una dosis subletal (1 µg/g) de veneno del escorpión Tityus discrepans (VTd), se usaron ratones hembras de la raza BALB/c con un peso de 20±2g (n=20). Los ratones fueron anestesiados y se obtuvieron muestras de sangre por cardiocentesis a las 0 h, 3 h, 6 h y 12 h después de administrado el VTd. Los análisis hematológicos fueron realizados por procedimientos rutinarios. Se observó un aumento significativo (p<0,05) en el hematocrito, la concentración de hemoglobina y la concentración de proteínas plasmáticas a las 3 h y 6 h, posiblemente debido a deshidratación, contracción esplénica e inducción de proteínas de fase aguda. El conteo de glóbulos rojos en ratones envenenados fue significativamente (p<0,05) mayor en comparación con el control sólo a las 12 h. El VTd causó neutrofilia y linfopenia probablemente debido a la liberación de catecolaminas, sin observarse cambios significativos (p>0,05) en el conteo total de leucocitos. Ni el número de plaquetas ni los índices hematimétricos fueron afectados significativamente (p>0,05) por la administración de VTd. Considerando los hallazgos, la administración de VTd induce alteraciones en el perfil hematológico en ratones.

Risk Factors of Emergence Agitation in Adults Undergoing General Anesthesia for Nasal Surgery

OBJECTIVES: To identify the incidence and the risk factors of emergence agitation in adults undergoing general anesthesia for nasal surgery. METHODS: We retrospectively examined 792 patients aged > or =18 years who underwent general anesthesia for elective nasal surgery between July 2012 and August 2013. Patients in the postanesthesia care unit with a Richmond Agitation Sedation Scale> or =+1 at any time were considered to have emergence agitation. RESULTS: The overall incidence of emergence agitation is 22.2%. From multivariate regression analysis, the following six variables were found to be significantly associated with emergence agitation (P or =5, presence of a tracheal tube, and presence of a urinary catheter. Presence of a tracheal tube was the greatest risk factor, increasing the risk of developing emergence agitation by approximately fivefold (odds ratio, 5.448; 95% confidence interval, 2.973 to 9.982). Younger age was also a strong risk factor (odds ratio, 0.975 for each 1-year increase; 95% confidence interval, 0.964 to 0.987). Current smoking, sevoflurane anesthesia, postoperative pain of NRS> or =5, and the presence of a urinary catheter nearly doubled the risk of emergence agitation. CONCLUSION: Emergence agitation following general anesthesia is a common complication in adult nasal surgery patients. To reduce the occurrence and consequences of agitation episodes, elimination of the associated risk factors is necessary, especially in at-risk patients.
