Objective: This study aimed to evaluate oral and maxillofacial trauma caused by falls during epileptic seizures., Method: A prospective case-control study was carried out among patients recruited from both the Epileptic Outpatient Clinic and the Emergency Room of Hospital de Base during 2006. The study group was composed of patients with epilepsy that had been diagnosed by a specialist. Oral and maxillofacial trauma was diagnosed using a questionnaire together with physical and radiographic examinations. A control group was formed from non-epileptic relatives or neighbors of the patients. The two groups were compared with regard to the number and type of oral and maxillofacial trauma events suffered. Odds ratios with a 95% confidence interval, dependency analysis and the Pearson χ(2) test were used for statistical analysis, and the significance level was set at p≤0.05., Results: A total of 159 patients with epilepsy (91 males; 57.3%) and 68 control individuals (28 males; 41.1%) were enrolled in the study. The frequencies of oromaxillary trauma in the study and control groups were 23.9% and 4.4%, respectively. Generalized tonic-clonic, generalized and non-classified seizures were strongly associated with trauma. The commonest lesions were fractures of dental tooth crowns (32.9%), followed by tooth avulsion (7.6%), tooth luxation (5%) and fracturing of prostheses in edentulous patients (3.8%)., Conclusion: This work shows that injuries to the face and teeth are statistically more common in patients with epilepsy than in the general population, and that individuals who suffer seizures without aura are the most affected.

Objective: To determine the survival rate according to the main findings of emergency electroencephalography (EEGs) of patients treated in a tertiary hospital., Method: In this prospective study, the findings of consecutive emergency EEGs performed on inpatients in Hospital de Base in São José do Rio Preto, Brazil were correlated with survival utilizing Kaplan-Meyer survival curves., Results: A total of 681 patients with an average age of 42 years old (1 day to 96 years) were evaluated, of which 406 were male. The main reasons for EEGs were epileptic seizures (221 cases), hepatic encephalopathy [116 cases of which 85 (73.3%) were men, p-value=0.001], status epilepticus (104 cases) and impaired consciousness (78 cases). The underlying disease was confirmed in 578 (84.3%) cases with 119 (17.5%) having liver disease [91 (76.0%) were men, p-value=0.001], 105 (15.4%) suffering strokes, 67 (9.9%) having metabolic disorders, 51 (7.5%) central nervous system infections and 49 (7.2%) epilepsy. In the three months following EEG, a survival rate of 75% was found in patients with normal, discreet slow activity or intermittent rhythmic delta activity EEGs, of 50% for those with continuous delta activity and generalized epileptiform discharges, and of 25% for those with burst-suppression, diffuse depression, and in alpha/theta-pattern coma. Death was pronounced immediately in patients with isoelectric EEGs., Conclusion: The main findings of EEGs, differentiated different survival rates and are thus a good prognostic tool for patients examined in emergencies.

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.

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.

Objective: To assess the epilepsy treatment gap in Campinas and São Josédo Rio Preto, two cities in the State of São Paulo, Brazil., Method: The treatment gap was estimated using the formula n1-n2/n1x100, where n1 was calculated using 1.86% prevalence and represented the number of individuals with epilepsy, while n2 represented the number of people who could be treated with an adult standard dose for a year utilizing the antiepileptic drugs supplied by the public health system., Results: Our estimates revealed that in 2001, approximately 50% of the population with epilepsy was treated with the recommended antiepileptic medication., Conclusion: These results suggest that a relevant percentage of patients with epilepsy are not untreated. Further epidemiological studies are needed to investigate the reasons for this treatment gap so that interventions can reduce this gap and improve the quality of life of patients with epilepsy.

Unlabelled: The aim of this study was to determine the prevalence of epilepsy in the urban population of São José do Rio Preto. This is a medium-sized city of 336000 inhabitants, located in the northwest of the state of São Paulo, Brazil., Method: A cross-sectional epidemiological investigation with a randomized sample was performed in two phases, a screening phase and a confirmation of the diagnosis phase. The gold standard was a clinical investigation and neurological examination. The chi-square test was used in analysis of the results and p-value value < 0.05 was considered significant. Prevalence was calculated with 95% confidence interval., Results: The study sample size was 17293 individuals, with distributions of gender, age, and race similar to the general population. The prevalence per 1000 inhabitants of epilepsy was 18.6, of these 8.2 were active, defined as at least one seizure within the last two years. The prevalence per 1000 inhabitants for the age groups (years) was 4.9 (04), 11.7 (514), 20.3 (1564) and 32.8 (65 or over)., Conclusion: Prevalence of both accumulated and active epilepsy was elevated, comparable to other developing nations, in particular those of Latin America. However, the prevalence of epilepsy in childhood was low, whilst in aged individuals it was high similar to industrialized nations.

The purpose of this cross-sectional study was to evaluate the prevalence of epilepsy in a population based sample: the Bakairi indians, who live on the banks of Paranatinga river in the central plateau of Mato Grosso state, Brazil. This population is composed of 483 inhabitants. The study was outlined in two stages, and the investigation was door-to-door in a total of 103 houses. The results of the instrument showed a sensitivity of 88% (CI- 95%, 84.9-93), specificity of 97.8% (CI-95, 95-98). The prevalence of active epilepsy was 12.4 per mil, and inactive was 6.2 per mil. This prevalence of the epilepsy was considered high probably due to some familial risk factor (p=0.04) among those Indians, while other factors were not important.

We report a case of Aicardi syndrome in a female child with 2 month old, ocular abnormalities "chorioretinal lacunae", flexion in spasms, hipsarrhythmic "split brain", callosal agenesis referred to Service of Neuropediatric and Neurophysiology of Base Hospital of São José do Rio Preto, SP, Brazil.

This study aims to evaluate, prospectively, the epileptic syndromes and seizures types upon work based on a sample of 412 out-patients from Hospital de Base, São José do Rio Preto, SP, Brazil. It was observed that the epileptic syndromes were significant in relation to the patients' labor skills (p= 0.001): the idiopathic syndromes showed less prejudiced, while the symptomatic was more. The seizures types also had some influence in relation to the patients' labor skills (p=0.016): the generalized non-convulsive seizures had no involvement; the simple partial and the non-classified had moderately involvement; and the simple partial seizures evolving to complex and tonic-clonic generalized were the seizures which mostly have taken the patients away from work. The seizure severity was also analyzed.

This study aims to evaluate, prospectively, the relationship of the active epilepsy length and the work, of the 379 out-patients from Hospital de Base, São José do Rio Preto. Epilepsy length was subdivided into 5 time rates and by age, into 3 age-groups. There was no relationship, not considering the age of patient among the epilepsy length and the work, but young patient (14 at 29 years old) and with recent epilepsy (length of 0 at 5 years) lost more work than the adult and elderly epileptic.

This study aims to assess epileptic patients migration in different sorts of paid/non paid and formal/informal work, unemployment and retirement. Eighty one epileptic patients were evolutively analyzed (cohort) at the Epilepsy Department of Hospital de Base, Medical School, São José do Rio Preto, Brazil. The epileptic percentages in different sorts of work, in March 1996 was compared with the one after three-year follow-up period in March 1999. There were no statistical significant changes among the same sorts of work in this period. However, there were intense migrations in relation to different sorts of work. Paid work showed migration to unemployment and retirement. This research shows the significant migration of epileptic patient either to some kind of a less qualified work or to some social security dependence as well as to early retirement.

Unlabelled: This study aims to determine the age at which the rolandic spikes (RS) appear and disappear in routine EEGs., Method: It has been carried out a hospital based prospective study of 412 EEGs records of 160 children who had been assisted at the neuropediatric out-patient department during the period between March, 1989 and March, 1998. Recordings were made on 8-channel instruments and 10/20 system has been to place the electrodes. The children have been divided into 4 groups, according to their age (1 to 4; 5 to 8; 9 to 16; 1 to 16), and the actuarial curve method has been used to show the disappearance of the rolandic spikes., Results: RS distribution between boys and girls has been 64/36 ratio. RS have been found at average age of 7 years (boys, 7.2 and girls, 6.6). In a small group of children with normal EEGs previous to the RS appearance, the average age has been 6.8 years old. After this 7-year follow up period, the percentage of patients free from RSs was 60% for 1 to 4 year old group at admission; 84% for the 5 to 8 year old group and for the 9 to 16 year old group. For the total group (1 to 16 year old), the percentage of those free from RSs after this 7 year follow up period was 78%., Conclusion: This study shows that RSs appear at the average age of 7 years old, and are likely to disappear up to the end of a 7-year follow up period, independently on the appearance age.
