Interictal SPECT in the presurgical evaluation in epileptic patients with normal MRI or bilateral mesial temporal sclerosis SPECT intercrítico na avaliação pré-cirúrgica de pacientes epiléticos com ressonância magnética normal ou esclerose mesial temporal bilateral

The aim of this study was to evaluate the sensitivity of interictal compared to ictal SPECT in the lateralization of the epileptogenic focus in refractory temporal lobe epilepsy (TLE) patients that present with normal magnetic resonance imaging (MRI) or bilateral mesial temporal sclerosis (MTS). Thirty patients with TLE, for whom MRI examinations were normal or who presented with bilateral MTS, were retrospectively studied. Using a confidence interval of 95% and a level of significance for p-value O objetivo deste estudo foi avaliar a sensibilidade do SPECT interictal, em relação ao ictal, na lateralização do foco epileptogênico, de pacientes com epilepsia refratária de lobo temporal (ELT) que apresentam ressonância magnética (RM) normal ou esclerose mesial temporal (EMT) bilateral. Foram estudados retrospectivamente 30 pacientes com ELT, nos quais os exames de RM eram normais ou apresentavam EMT bilateral. Avaliada a sensibilidade do SPECT interictal em relação ao ictal, obtivemos taxa estimada de acerto de 73% com taxa mínima de acerto de 57%, adotando intervalo de confiança de 95% e índice de significância p<0,05. Conclui-se que o SPECT interictal é necessário apenas quando associado ao SPECT ictal, e não substitui a realização do ictal na localização da AE em pacientes com RM normal ou EMT bilateral

Projeto demonstrativo em epilepsia no Brasil: avaliação situacional

PURPOSE: To provide a situation assessment of services for people with epilepsy in the context of primary health care, as part of the Demonstration Project on Epilepsy in Brazil, part of the WHO/ILAE/IBE Global Campaign 'Epilepsy out of the shadows'. METHODS: We performed a door-to-door epidemiological survey in three areas to assess the prevalence of epilepsy and its treatment gap. We surveyed a sample of 598 primary health care workers from different regions of Brazil to assess their perceptions of the management of people with epilepsy in the primary care setting. RESULTS: The lifetime prevalence of epilepsy was 9.2/1,000 people [95% CI 8.4-10.0] and the estimated prevalence of active epilepsy was 5.4/1,000 people. Thirty-eight percent of patients with active epilepsy were on inadequate treatment, including 19% who were taking no medication. The survey of health workers showed that they estimated that 60% of patients under their care were seizure-free. They estimated that 55% of patients were on monotherapy and that 59% had been referred to neurologists. The estimated mean percentage of patients who were working or studying was 56%. Most of the physicians (73%) did not feel confident in managing people with epilepsy. DISCUSSION: The epidemiological survey in the areas of the Demonstration Project showed that the prevalence of epilepsy is similar to that in other resource-poor countries, and that the treatment gap is high. One factor contributing to the treatment gap is inadequacy of health care delivery. The situation could readily be improved in Brazil, as the primary health care system has the key elements required for epilepsy management. To make this effective and efficient requires: i) an established referral network, ii) continuous provision of AEDs, iii) close monitoring of epilepsy management via the notification system (Sistema de Informação da Atenção Básica - SIAB) and iv) continuous education of health professionals. The educational program should be broad spectrum and include not only medical management, but also psycho-social aspects of epilepsy.OBJETIVO: Avaliar a situação da assistência à epilepsia no contexto da atenção primária sob o Projeto Demonstrativo em epilepsia no Brasil, parte da Campanha Global Epilepsia Fora das Sombras da WHO/ILAE/IBE. MÉTODO: Fizemos um levantamento epidemiológico para definir a prevalência e lacuna de tratamento em epilepsia. Avaliamos a percepção de 598 profissionais de saúde da atenção básica de diferentes regiões do Brasil sobre epilepsia e seu manejo na rede básica de saúde. RESULTADOS: A prevalência acumulada de epilepsia foi de 9,2/1000 pessoas (95%IC= 8,4-10) e a prevalência estimada de epilepsia ativa foi de 5,4/1000 pessoas. Trinta e oito porcento dos pacientes com epilepsia ativa estavam sendo tratados inadequadamente, incluindo 19% que estavam sem medicação. A enquete com os profissionais de saúde mostrou que a média estimada de pacientes livre de crises sob os cuidados dos mesmos era de 60%. A média estimada de porcentagem em monoterapia era de 55%. A média estimada de porcentagem de referência para neurologistas era de 59%. A média estimada de porcentagem de pacientes que estavam trabalhando ou estudando era de 56%. A maioria dos médicos não se sente confiante em atender uma pessoa com epilepsia. DISCUSSÃO: A análise situacional da Fase I - estudo epidemiológico nas áreas de interesse do PD mostrou que a prevalência da epilepsia é similar a outros países em desenvolvimento e a lacuna de tratamento é grande. Um dos fatores importantes para a lacuna de tratamento é a falta de adequação à assistência na atenção básica. Essa situação pode ser revertida no Brasil, pois os elementos chaves existem na rede básica para o manejo de pessoas com epilepsia. Entretanto, para torna efetivo e eficiente é preciso i) estabelecimento de um sistema de referência e contra-referência, ii) fornecimento contínuo de medicação anti-epiléptica, iii) monitorização de manejo de pessoas com epilepsia através de sistema de notificação (SIAB - Sistema de Informação da Atenção Básica), e iv) educação continuada de profissionais de saúde. O programa educacional deve ser amplo incluindo não somente manejo médico, mas também aspectos psico-sociais.51

Demonstration project on epilepsy in Brazil: outcome assessment Projeto demonstrativo em epilepsia no Brasil: avaliação do desfecho

PURPOSE: To assess the outcome of patients with epilepsy treated at primary care health units under the framework of the demonstration project on epilepsy in Brazil, part of the WHO/ILAE/IBE Global Campaign Against Epilepsy. METHOD: We assessed the outcome of patients treated at four primary health units. The staff of the health units underwent information training in epilepsy. The outcome assessment was based on: 1) reduction of seizure frequency, 2) subjective perception from the patient’s and the physician’s point of view, 3) reduction of absenteeism, 4) social integration (school and work), and 5) sense of independence. RESULTS: A total of 181 patients (93 women - 51%) with a mean age of 38 (range from 2 to 86) years were studied. The mean follow-up was 26 months (range from 1 to 38 months, 11 patients had follow-up of less than 12 months). Seizure frequency was assessed based on a score system, ranging from 0 (no seizure in the previous 24 months) to 7 (>10 seizure/day). The baseline median seizure-frequency score was 3 (one to three seizures per month). At the end of the study the median seizure-frequency score was 1 (one to three seizures per year). The patients’ and relatives’ opinions were that in the majority (59%) the health status had improved a lot, some (19%) had improved a little, 20% experienced no change and in 2% the health status was worse. With regard to absenteeism, social integration and sense of independence, there were some modest improvements only. DISCUSSION: The development of a model of epilepsy treatment at primary health level based on the existing health system, with strategic measures centred on the health care providers and the community, has proved to be effective providing important reductions in seizure frequency, as well as in general well being. This model can be applied nationwide, as the key elements already exist provided that strategic measures are put forward in accordance with local health providers and managers.<br>OBJETIVO: Avaliar o resultado do tratamento de pacientes com epilepsia na atenção básica sob o modelo proposto pelo Projeto Demonstrativo no Brasil, como parte da Campanha Global Contra a Epilepsia da WHO/ILAE/IBE. MÉTODO: Avaliamos o resultado do tratamento nos pacientes acompanhados em quatro unidades básicas de saúde. As equipes de saúde fizeram um treinamento padrão. O resultado do tratamento foi baseado em cinco aspectos: 1) redução da freqüência das crises, 2) percepção subjetiva dos pacientes e dos médicos, 3) redução de absenteísmo, 4) integração social (escola, trabalho), e 5) senso de independência. RESULTADOS: Um total de 181 pacientes (93 mulheres - 51%), com uma média de 38 anos (variando de 2 a 86 anos) entraram nesta análise. O tempo médio de seguimento foi de 26 meses (variou de 1 a 38 meses, 11 pacientes tinham seguimento menos de 12 meses). A freqüência das crises foi categorizada variando de 0 (sem nenhuma crise nos últimos 24 meses) a 7 (>10 crises/dia). O escore mediano da freqüência de crises no começo era de 3 (uma a três crises por mês). O escore mediano da freqüência de crises no final era de 1 (uma a três crises por ano). A opinião dos pacientes e familiares é que a maioria (106 casos) houve uma melhora importante na saúde, 34 tiveram pouca melhora, 37 não tiveram mudanças e em quatro houve piora. Em relação ao absenteísmo, integração social e senso de independência houve pouca melhora. DISCUSSÃO: O modelo desenvolvido de tratamento de epilepsia na atenção primária com base na estrutura de saúde existente, com estratégias centradas nos profissionais de saúde e na comunidade, provou ser efetivo com redução importante na freqüência das crises bem como na melhora em geral da saúde. Esse modelo pode ser aplicado em âmbito nacional, pois os elementos chaves já existem, desde que essas estratégias sejam pactuadas com os organismos locais de saúde

Brazilian Flora 2020: Leveraging the power of a collaborative scientific network

International audienceThe shortage of reliable primary taxonomic data limits the description of biological taxa and the understanding of biodiversity patterns and processes, complicating biogeographical, ecological, and evolutionary studies. This deficit creates a significant taxonomic impediment to biodiversity research and conservation planning. The taxonomic impediment and the biodiversity crisis are widely recognized, highlighting the urgent need for reliable taxonomic data. Over the past decade, numerous countries worldwide have devoted considerable effort to Target 1 of the Global Strategy for Plant Conservation (GSPC), which called for the preparation of a working list of all known plant species by 2010 and an online world Flora by 2020. Brazil is a megadiverse country, home to more of the world's known plant species than any other country. Despite that, Flora Brasiliensis, concluded in 1906, was the last comprehensive treatment of the Brazilian flora. The lack of accurate estimates of the number of species of algae, fungi, and plants occurring in Brazil contributes to the prevailing taxonomic impediment and delays progress towards the GSPC targets. Over the past 12 years, a legion of taxonomists motivated to meet Target 1 of the GSPC, worked together to gather and integrate knowledge on the algal, plant, and fungal diversity of Brazil. Overall, a team of about 980 taxonomists joined efforts in a highly collaborative project that used cybertaxonomy to prepare an updated Flora of Brazil, showing the power of scientific collaboration to reach ambitious goals. This paper presents an overview of the Brazilian Flora 2020 and provides taxonomic and spatial updates on the algae, fungi, and plants found in one of the world's most biodiverse countries. We further identify collection gaps and summarize future goals that extend beyond 2020. Our results show that Brazil is home to 46,975 native species of algae, fungi, and plants, of which 19,669 are endemic to the country. The data compiled to date suggests that the Atlantic Rainforest might be the most diverse Brazilian domain for all plant groups except gymnosperms, which are most diverse in the Amazon. However, scientific knowledge of Brazilian diversity is still unequally distributed, with the Atlantic Rainforest and the Cerrado being the most intensively sampled and studied biomes in the country. In times of “scientific reductionism”, with botanical and mycological sciences suffering pervasive depreciation in recent decades, the first online Flora of Brazil 2020 significantly enhanced the quality and quantity of taxonomic data available for algae, fungi, and plants from Brazil. This project also made all the information freely available online, providing a firm foundation for future research and for the management, conservation, and sustainable use of the Brazilian funga and flora
