Demonstration Project on Epilepsy in Brazil: situation assessment.

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.

Demonstration project on epilepsy in Brazil: outcome assessment.

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 patients and the physicians 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.

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 por centoIC= 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 por cento 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 por cento. A média estimada de porcentagem em monoterapia era de 55 por cento. A média estimada de porcentagem de referência para neurologistas era de 59 por cento. A média estimada de porcentagem de pacientes que estavam trabalhando ou estudando era de 56 por cento. 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...

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 por cento), 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.

Prevalence and pattern of epilepsy treatment in different socioeconomic classes in Brazil.

PURPOSE: The worldwide prevalence of epilepsy is variable, estimated at 10//1,000 people, and access to treatment is also variable. Many people go untreated, particularly in resource-poor countries. OBJECTIVE: To estimate the prevalence of epilepsy and the proportion of people not receiving adequate treatment in different socioeconomic classes in Brazil, a resource-poor country. METHODS: A door-to-door survey was conducted to assess the prevalence and treatment gap of epilepsy in three areas of two towns in Southeast Brazil with a total population of 96,300 people. A validated screening questionnaire for epilepsy (sensitivity 95.8%, specificity 97.8%) was used. A neurologist further ascertained positive cases. A validated instrument for socioeconomic classification was used. RESULTS: Lifetime prevalence was 9.2/1,000 people [95% CI 8.4-10.0] and the prevalence of active epilepsy was 5.4/1,000 people. This was higher in the more deprived social classes (7.5/1,000 compared with 1.6/1,000 in the less deprived). Prevalence was also higher in elderly people (8.5/1,000). Thirty-eight percent of patients with active epilepsy had inadequate treatment (19% on no medication); the figures were similar in the different socioeconomic groups. CONCLUSION: The prevalence of epilepsy in Brazil is similar to other resource-poor countries, and the treatment gap is high. Epilepsy is more prevalent among less wealthy people and in elderly people. There is an urgent need for education in Brazil to inform people that epilepsy is a treatable, as well as preventable, condition.

Sleep parameters in patients using pacemakers with sleep rate function on.

INTRODUCTION: The cardiovascular system (CVS) is heavily influenced by the autonomic nervous system. Additionally, there is a functional alteration during the various stages of sleep. In nonrapid eye movement (NREM), a state of cardiovascular relaxation occurs during stages three and four. A large amount of rapid ocular movements is concentrated in rapid eye movement (REM) sleep. During this phase, fluctuations in arterial pressure (AP) and heart rate (HR) can be readily noted. Sleep disordered breathing (SDB) has been associated with cardiac rhythm disorders. Recently, cardiac rhythm disorder treatment with pacemaker (PM) highlighted a reduction in abnormal respiratory events during sleep. OBJECTIVE: Comparison of sleep parameters of patients using PM with a sleep rate (SR) algorithm based on its rate-modulated capability during physical activity (Integrity PM with SR function on and off). METHODS: Twenty-two patients (14 women, 8 men), implanted with an Integrity PM (St. Jude Medical Cardiac Rhythm Management Division, Sylmar, CA) with SR function for standard clinical indications, were evaluated utilizing a double-blind protocol. The indication for pacing included sinus node disease (SND), atrium ventricular blockage (AVB), and atrial fibrillation (AF). Following randomization, half of our patients had SR function switched to "on" mode while the other half were on "off" mode. During the first stage of the protocol, all patients underwent two consecutive nights of polysomnographic sleep recordings (PSG). During the first night patients slept in the sleep lab only for adaptation purpose. PSG full recording was carried out in the subsequent night. At a later stage, the programing of SR functions was shifted to "on" or "off" modes. One week later, a third assessment was undertaken. RESULTS: Twelve patients (54%) showed sleep efficiency improvement (total sleeping time/recording time) with PM SR on. This group had the least effective sleep efficiency with PM off, if compared with the others who highlighted no change in this sleep parameter (72 +/- 12 vs 81 +/- 7%, P = 0.01, respectively). This first group displayed a lower latency for REM sleep than the last one (89 +/- 55 vs 174 +/- 107 minutes, P = 0.01, respectively). In 11 (50%) patients, the number per sleep hour of microarousals was reduced when PM SR was switched on. When we compared such findings to the group whose parameters had not changed, we noted that the first set of patients were sleepier (ESE: 9 +/- 4 vs 5 +/- 5, P = 0.04, respectively), and showed more microarousals with PM SR off (20 +/- 14 vs 7 +/- 5 microarousal/hour, P = 0.007). CONCLUSION: In PM patients with sleep-related issues, the SR function activation improved sleep both from a qualitative and quantitative perspective.

Idade de aparecimento e desaparecimento das pontas rolândicas em 160 crianças acompanhadas ambulatorialmente: estudo atuarial / Age of appearance and disappearance of rolandic spikes of 160 children treated in ambulatory: actuarial study

Proposta: Determinar a idade em que surgem e desaparecem as pontas rolândicas (PR) em traçados eletrencefalográficos de rotina. Método: Estudo prospectivo hospitalar, baseado em 412 eletrencefalogramas de 160 crianças que frequentaram o ambulatório de neuropediatria entre as idades de 1 e 16 anos, no período de março de 1989, a março de 1998. Usou-se o sistema 10/20 para colocação dos eletrodos. As crianças foram divididas, por idade, em quatro grupos (1 a 4;5 a 8;9 a 16;1 a 16) e usou-se o método de curva atuarial, considerando-se como evento, o desaparecimento da PR. Resultados: PR teve distribuição entre meninos e meninas na razão de 64/36. A idade média em que surgiu a PR foi 7 anos (7,2 para homens e 6,6 para mulheres) e, num pequeno grupo de crianças que tinha EEG normal anterior ao surgimento da PR, a idade média foi 6,8 anos. Após 7 anos de seguimento, a percentagem de pacientes livres de PRs era 60 por cento para o grupo de 1 a 4 anos na admissão, 84 por cento para os grupos de 5 a 8 anos e 9 a 16 anos. Para o grupo total (1 a 16 anos) a percentagem de livres de PR, após 7 anos de seguimento, foi 78 por cento. Conclusão: O estudo mostra que as PR surgiram, em média, aos 7 anos e têm probabilidade de desaparecimento até 7 anos de seguimento, independetemente da faixa etária de aparecimento.
