RESUMO Os canabinoides compreendem os endocanabinoides, fitocanabinoides e os canabinoides sintéticos e desempenham ações no sistema nervoso central e periférico. Uma quantidade enorme de publicações tem sido lançada nos últimos anos, embora a cannabis seja conhecida por milênios. Os Departamentos Científicos da Academia Brasileira de Neurologia descreveram as evidências do uso médico em suas áreas. A literatura está em constantes mudanças e possíveis novas evidências podem surgir nos próximos dias ou meses. A prescrição dessas substâncias deve ser discutida com os pacientes e suas famílias, com conhecimento sobre eventos adversos e sua eficácia.

ABSTRACT Cannabinoids comprehend endocannabinoids, phytocannabinoids, and synthetic cannabinoids, with actions both in the central and peripherical nervous systems. A considerable amount of publications have been made in recent years, although cannabis has been known for over a thousand years. Scientific Departments from the Brazilian Academy of Neurology described evidence for medical use in their areas. Literature is constantly changing, and possible new evidence can emerge in the next days or months. Prescription of these substances must be discussed with patients and their families, with knowledge about adverse events and their efficacy.

BACKGROUND Paracoccidioidomycosis (PCM) is a systemic mycosis endemic to Latin America. Etiological agents are Paracoccidioides species that diverge phylogenetically throughout South America. OBJECTIVES This study aimed to document the epidemiology of PCM in Venezuela. METHODS We have performed a retrospective cross-sectional descriptive study in 31,081 clinical records of patients from two reference centres during 65 years (1954-2019). FINDINGS PCM diagnosis was confirmed in 745 patients. Chronic PCM was the most prevalent form (90.06% cases); 80.67% were male and the most affected age range was 41-60. Farming and construction were the most prevalent occupation and Miranda State had a higher prevalence. Lung and skin were the most affected organs, followed by oral manifestations. Direct examination, culture and serology showed a high sensibility, and no statistical difference was observed among the diagnostic tools. Out of 17 Paracoccidioides isolates genotyped from Venezuela, one was typed as Paracoccidioides americana and 16 as Paracoccidioides venezuelensis. MAIN CONCLUSIONS Clinical manifestations observed, information about the epidemiology and molecular profile is essential not only for diagnosis but also for understanding therapeutic responses to mycotic drugs and prognosis. Therefore, it is necessary to sequence all positive isolated strains in order to confirm the dominance of P. venezuelensis in Venezuela.

RESUMO Objetivo: Avaliar a acurácia dos níveis de interleucina 3 para predizer prognóstico em pacientes sépticos. Métodos: Conduzimos uma coorte prospectiva que incluiu pacientes adultos internados em unidade de terapia intensiva, que apresentassem sepse ou choque séptico iniciados há até 48 horas. Mediram-se os níveis séricos de interleucina 3 quando da inclusão (dia 1) e nos dias 3 e 7. O desfecho primário analisado foi a mortalidade hospitalar por qualquer causa. Resultados: Foram incluídos 120 pacientes. Os níveis séricos de interleucina 3 dosados à inclusão foram significativamente mais elevados em pacientes que faleceram em comparação aos que sobreviveram à internação hospitalar (91,2pg/mL versus 36pg/mL; p = 0,024). Em modelo de sobrevivência de Cox com inclusão de idade e valores sequenciais de SOFA, os níveis de interleucina 3 mensurados na inclusão mantiveram-se independentemente associados à mortalidade hospitalar (HR 1,032; IC95% 1,010 - 1,055; p = 0,005). Em curva Característica de Operação do Receptor construída para investigação adicional da acurácia da interleucina 3 na predição do prognóstico, encontrou-se área sob a curva de 0,62 (IC95% 0,51 - 0,73; p = 0,024) para mortalidade hospitalar. Valores iniciais de interleucina 3 acima de 127,5pg/mL mostraram-se significativamente associados à mortalidade hospitalar (p = 0,019; OR = 2,97; IC95% 1,27 - 6,97; p = 0,019), entretanto com baixo desempenho (especificidade de 82%, sensibilidade de 39%, valor preditivo positivo de 53%, valor preditivo negativo de 72%, razão de verossimilhança negativa de 0,73 e razão de verossimilhança positiva de 2,16). Conclusão: Níveis elevados de interleucina 3 mostraram-se independentemente associados à mortalidade hospitalar em pacientes sépticos, entretanto com baixo desempenho clínico.

ABSTRACT Objective: To evaluate the accuracy of IL-3 to predict the outcome of septic patients. Methods: Prospective cohort study with adult patients in an intensive care unit with sepsis or septic shock diagnosed within the previous 48 hours. Circulating IL-3 levels were measured upon inclusion (day 1) and on days 3 and 7. The primary outcome was hospital mortality. Results: One hundred and twenty patients were included. Serum levels of IL-3 on day 1 were significantly higher among patients who died than among patients who survived the hospital stay (91.2pg/mL versus 36pg/mL, p = 0.024). In a Cox survival model considering the IL-3 levels at inclusion, age and sequential SOFA, IL-3 values remained independently associated with mortality (HR 1.032; 95%CI 1.010 - 1.055; p = 0.005). An receiver operating characteristic curve was built to further investigate the accuracy of IL-3, with an area under the curve of 0.62 (95%CI 0.51 - 0.73; p = 0.024) for hospital mortality. A cutoff initial IL-3 value above 127.5pg/mL was associated with hospital mortality (OR 2.97; 95%CI: 1.27 - 6.97; p = 0.0019) but with a low performance (82% for specificity, 39% for sensibility, 53% for the positive predictive value, 72% for the negative predictive value, 0.73 for the negative likelihood and 2.16 for the positive likelihood ratio). Conclusion: Higher levels of IL-3 are shown to be independently associated with hospital mortality in septic patients but with poor clinical performance.

RESUMO O trabalho faz reflexões sobre o patrimônio cultural no âmbito das escolas de ensino médio, analisando algumas iniciativas de levantamentos e de valoração dos objetos de ensino enquanto bens culturais. Para tanto, buscamos traçar um perfil analítico de projetos de inventário desse patrimônio cultural no Brasil e em Portugal. A partir das lentes da ciência e tecnologia, utilizou-se a revisão bibliográfica e os contatos com as instituições como metodologia para comparar o estado de pesquisas de inventário sobre estes objetos. Observou-se que as iniciativas aqui estudadas são assimétricas, necessitando ser padronizadas e aprofundadas de forma a alcançar as diferentes modalidades de ensino e, consequentemente, obter resultados mais consistentes e efetivos do ponto de vista da preservação. No entanto, percebe-se que existe um movimento crescente de identificação e preservação desses artefatos nos dois países.

ABSTRACT This study offers some reflections about cultural heritage in secondary schools, analyzing some initiatives to survey and enhance the value of teaching objects as cultural assets. An analytical profile of inventories of cultural heritage at secondary schools in Brazil and Portugal is presented. Considering the perspective of science and technology heritage, the methodology involved a literature review and direct contact with institutions to survey and compare the state of inventory-based research of such objects. The initiatives studied here were found to be asymmetrical, requiring standardization and more in-depth analysis to encompass different types of education, thus obtaining more consistent and effective results from a preservation perspective. Nonetheless, there is a growing movement to identify and preserve these artifacts in both countries.

Resumo A paracoccidioidomicose (PCM) é uma micose sistêmica, relacionada às atividades agrícolas, com incidência e prevalência subestimadas, pela ausência de notificação em várias Unidades da Federação (UFs). A evolução insidiosa do quadro clínico pode ter como consequência sequelas graves se o diagnóstico e o tratamento não forem instituídos precoce e adequadamente. Ao lado do complexo Paracoccidioides brasiliensis (P. brasiliensis), a descrição de nova espécie, Paracoccidioides lutzii (P. lutzii), em Rondônia, onde a doença alcançou níveis epidêmicos, bem como na região Centro-Oeste e no Pará, constituem-se em desafios para a instituição do diagnóstico e a urgente disponibilização de antígenos que tenham reatividade com os soros dos pacientes. Este consenso visa atualizar o primeiro consenso brasileiro em PCM, estabelecendo recomendações para o manejo clínico do paciente, com base nas evidências conhecidas. São apresentados dados de etiologia, epidemiologia, imunopatogenia, diagnóstico, terapêutica e sequelas, enfatizando-se o diagnóstico e a terapêutica, bem como recomendações e desafios atuais nessa área do conhecimento.

Abstract Paracoccidioidomycosis is a systemic fungal disease associated with agricultural activities. Its incidence and prevalence are underestimated because of the lack of reporting in several Brazilian states. If paracoccidiodomycosis is not diagnosed and treated early and adequately, endemic fungal infection may result in serious sequelae. In addition to the Paracoccidioides brasiliensis (P. brasiliensis) complex, the appearance of a new species, Paracoccidioides lutzii (P. lutzii), in Rondônia state, where the disease has reached epidemic levels, and in the country’s Midwest region and Pará state, are challenges to diagnosis and to the urgent availability of antigens that are reactive with patients’ sera. These guidelines aim to update the first Brazilian consensus on paracoccidioidomycosis by providing evidence-based recommendations for bedside patient management. The guidelines provide data on etiology, epidemiology, immunopathogenesis, diagnosis, treatment and sequelae, with emphasis on diagnosis and treatment, as well as current recommendations and challenges in this field of knowledge.

El presente consenso tiene por objeto actualizar el primer consenso brasileño en paracoccidioidomicosis, estableciendo recomendaciones para el manejo del paciente al borde del lecho, con base en las evidencias conocidas. Se presentan datos de etiología, epidemiología, inmunopatogenia, diagnóstico, terapéutica y secuelas, enfatizando el diagnóstico y terapéutica, así como recomendaciones desafíos y actuales en esta área del conocimiento.

RESUMO Epilepsia é um problema neurológico sério e para o qual não há um tratamento efetivo e definitivo. Apesar de o tratamento cirúrgico ser bastante benéfico em alguns casos, ainda é subutilizado. O objetivo deste trabalho é descrever a implementação de um Centro de Cirurgia de Epilepsia em um Hospital Universitário Federal, divulgar a experiência inicial obtida, os principais desafios, as dificuldades e os resultados iniciais. Método: Relato da experiência na implementação do Centro de Epilepsia. Análise retrospectiva de série de treze pacientes com epilepsia resistente a medicação e que foram submetidos a tratamento cirúrgico. Resultados: Treze pacientes submetidos a tratamento cirúrgico, 5 com a Liga Internacional Contra Epilepsia classe 1, 2 com classe 3, três com classe 3, zero com classe 4 e 2 com classe 5; com uma taxa de complicação de 30, 76%. Conclusão: Apesar das dificuldades, foi possível a implementação de um Centro de Cirurgia de Epilepsia com resultados favoráveis e taxas de complicação não superiores aos centros de países desenvolvidos.

ABSTRACT Epilepsy is a serious neurological condition, often without a full and effective treatment. In some cases, surgery is beneficial, despite being underused. Our aim herein is to describe the implementation of an epilepsy surgery center in a federal university hospital, sharing the initial experience gained, as well as describing the main challenges and first results. Methods: Experience report of an epilepsy surgery center implementation. Retrospective review of 13 drug-resistant patients who underwent surgical treatment. Results: Thirteen patients underwent surgical epilepsy treatment, five patients categorized as the International League Against Epilepsy class 1, two in class 2, three in class 3, zero in class 4, and two in class 5; with a 30.76% complication rate. Conclusion: Despite the challenges, it was possible to implement an epilepsy surgery center with favorable results and acceptable incidence of complications, which were not higher than the incidences found in more experienced centers.

Abstract Paracoccidioidomycosis is a systemic fungal disease occurring in Latin America that is associated with rural environments and agricultural activities. However, the incidence and prevalence of paracoccidiodomycosis is underestimated because of the lack of compulsory notification. If paracoccidiodomycosis is not diagnosed and treated early and adequately, the endemic fungal infection could result in serious sequelae. While the Paracoccidioides brasiliensis ( P. brasiliensis ) complex has been known to be the causal agent of paracoccidiodomycosis, a new species, Paracoccidioides lutzii ( P. lutzii ), has been reported in Rondônia, where the disease has reached epidemic levels, and in the Central West and Pará. Accurate diagnoses and availability of antigens that are reactive with the patients’ sera remain significant challenges. Therefore, the present guidelines aims to update the first Brazilian consensus on paracoccidioidomycosis by providing evidence-based recommendations for bedside patient management. This consensus summarizes etiological, ecoepidemiological, molecular epidemiological, and immunopathological data, with emphasis on clinical, microbiological, and serological diagnosis and management of clinical forms and sequelae, as well as in patients with comorbidities and immunosuppression. The consensus also includes discussion of outpatient treatments, severe disease forms, disease prevalence among special populations and resource-poor settings, a brief review of prevention and control measures, current challenges and recommendations.

BACKGROUND Fluorescence in situ hybridisation (FISH) associated with Tyramide Signal Amplification (TSA) using oligonucleotides labeled with non-radioactive fluorophores is a promising technique for detection and differentiation of fungal species in environmental or clinical samples, being suitable for microorganisms which are difficult or even impossible to culture. OBJECTIVE In this study, we aimed to standardise an in situ hybridisation technique for the differentiation between the pathogenic species Paracoccidioides brasiliensis and Paracoccidioides lutzii, by using species-specific DNA probes targeting the internal transcribed spacer-1 (ITS-1) of the rRNA gene. METHODS Yeast and mycelial phase of each Paracoccidioides species, were tested by two different detection/differentiation techniques: TSA-FISH for P. brasiliensis with HRP (Horseradish Peroxidase) linked to the probe 5’ end; and FISH for P. lutzii with the fluorophore TEXAS RED-X® also linked to the probe 5’ end. After testing different protocols, the optimised procedure for both techniques was accomplished without cross-positivity with other pathogenic fungi. FINDINGS The in silico and in vitro tests show no reaction with controls, like Candida and Cryptococcus (in silico) and Histoplasma capsulatum and Aspergillus spp. (in vitro). For both phases (mycelial and yeast) the in situ hybridisation showed dots of hybridisation, with no cross-reaction between them, with a lower signal for Texas Red probe than HRP-TSA probe. The dots of hybridisation was confirmed with genetic material marked with 4’,6-diamidino-2-phenylindole (DAPI), visualised in a different filter (WU) on fluorescent microscopic. MAIN CONCLUSION Our results indicated that TSA-FISH and/or FISH are suitable for in situ detection and differentiation of Paracoccidioides species. This approach has the potential for future application in clinical samples for the improvement of paracoccidioidomycosis patients prognosis.

Abstract: En | Text: En | PDF: En

Aureobasidium pullulans is a causal agent of phaeohyphomycosis, occasionally found in men and animals. As an agent of different opportunistic fungal processes, it may cause fungemia, systemic infections and abscesses in different viscera. This paper aims to report a case of a patient with infection of the lymphatic system by A. pullulans. A 23-year-old patient being treated for erythema nodosum leprosum presented a 60-day complaint of daily fever, hoarseness, odynophagia and weight loss. Laboratory tests showed pancytopenia with severe neutropenia, cervical adenomegaly and solid contrast uptake lesion in the oropharyngeal region. Due to neutropenia and sepsis the patient was initially treated with cefepime and vancomycin, but there was no clinical improvement. Lymph node puncture-aspiration showed yeast-form fungus identified as A. pullulans by sequencing ITS region. The patient was treated with amphotericin B deoxycholate, leading to complete recovery of bone marrow function and regression of adenomegaly and the oropharyngeal lesion.

OBJETIVO: A técnica do interruptor é usada para determinar interrupter resistance (Rint, medida de resistência das vias aéreas através da técnica do interruptor) durante respiração tranqüila. Este método não-invasivo requer mínima cooperação e, por isso, pode ser útil para avaliar obstrução de vias aéreas em crianças não-colaborativas. Não existem dados publicados de valores de referência para Rint na população brasileira até o momento. O objetivo deste estudo foi definir uma equação para prever a resistência das vias aéreas pela técnica do interruptor em crianças saudáveis de 3 a 13 anos de idade. MÉTODOS: Este estudo transversal prospectivo com crianças pré-escolares e escolares em Porto Alegre, Brasil, mensurou Rint durante pico de fluxo expiratório no volume corrente. RESULTADOS: Cento e noventa e três crianças completaram as medidas. Estatura, peso corporal e idade mostraram correlação significante e independente com Rint na análise univariada usando regressão linear. A regressão múltipla com estatura, peso corporal, idade e gênero como variáveis resultou em um modelo no qual somente estatura e peso corporal foram significativos e independentes para predizer Rint. Colinearidade foi identificada entre estatura, peso corporal e idade. CONCLUSÕES: Valores e equação de referência para Rint em crianças saudáveis foram obtidos e são relacionados a estatura.

OBJECTIVE: The interrupter technique is used for determining interrupter resistance (Rint) during quiet breathing. This noninvasive method requires minimal cooperation and can therefore be useful in evaluating airway obstruction in uncooperative children. To date, no reference values have been determined for Rint in a Brazilian population. The objective of this study was to define a prediction equation for airway resistance using the interrupter technique for healthy children aged 3-13 years. METHODS: This was a prospective, cross-sectional study involving preschool and school children in Porto Alegre, Brazil, in whom Rint was measured during peak expiratory flow. RESULTS: One-hundred and ninety-three children were evaluated. Univariate analysis using linear regression showed that height, weight and age correlated significantly and independently with Rint. Multiple regression with height, weight, age and gender as variables resulted in a model in which only height and weight were significant, independent predictors of Rint. Collinearity was identified among height, weight and age. CONCLUSIONS: Reference values and an equation for calculating Rint in healthy children were obtained and are adjusted for height.

Mais de 60.500 casos de dengue foram notificados no Espírito Santo, entre 1995 e 1998. Realizou-se estudo com o objetivo de averiguar se o mosquito Aedes albopictus estava transmitindo o vírus durante uma epidemia em Vila Bethânia (Viana), no sudeste de Vitória, capital capixaba. De 3 a 9 de abril de 1998, amostras de sangue e (ou) soro de pacientes foram coletadas e os mosquitos foram capturados diariamente, tanto para isolamento viral como para testes sorológicos. Em onze casos autóctonos, quatro foram confirmados por isolamento do vírus DEN 1, e dois por reação MAC ELISA Dos 37 Ae. aegypti e 200 Ae. albopictus adultos capturados e inoculados, apenas uma amostra de vírus DEN 1 foi obtida de um lote de duas fêmeas de Ae. aegypti. Os resultados sugerem que a espécie Ae. albopictus ainda não pode ser considerada um vetor inter-humano durante epidemias de dengue no Brasil.

Over 60,500 dengue cases were reported in the state of Espírito Santo (ES), Brazil, between 1995 and 1998. The study's purpose was to identify whether Aedes albopictus was transmitting the dengue virus during an epidemic in the locality of Vila Bethânia (Viana County),Vitória, ES. From April 3 to 9, 1998, blood and serum samples were collected daily for virus isolation and serological testing. Four autochthonous cases were confirmed through DEN 1 virus isolation and two autochthonous cases through MAC ELISA testing. Of 37 Ae. aegypti and 200 Ae. albopictus adult mosquitoes collected and inoculated, DEN1 virus was isolated only from a pool of two Ae. aegypti female mosquitoes. The study results suggest that Ae. albopictus still cannot be considered an inter-human vector in dengue epidemics in Brazil.
