-The attitudes toward people with epilepsy are influenced by the degree of knowledge of the condition. Teachers usually do not receive any formal instruction on epilepsy during their training. This study was done to access three hundred teachers knowledge and attitudes toward epilepsy by answering a questionnaire in order to quantify their knowledge, attitude and practice toward epilepsy. Almost all the teachers had heard about epilepsy yet could not demonstrate discrimination among the students. Some teachers still thought that epilepsy was contagious. A few others either objected to having epileptic children in their classes or did not think that an epileptic child could achieve higher studies. The knowledge about the clinical characteristics and initial procedures to attend a person during a seizure was unsatisfactory. We conclude that schools should offer some kind of knowledge or assistance in health services and physicians must ensure that these teachers have sufficient knowledge of epilepsy. Also general public education campaigns should be encouraged in this field.KEY WORDS: epilepsy, attitude, prejudice, public awareness.Atitude e percepção sobre epilepsia entre professores de primeiro, segundo e terceiro graus RESUMO -As atitudes referentes a pacientes com epilepsia são influenciadas pelo grau de conhecimento acerca desta patologia. Os professores geralmente não recebem instruções formais a este respeito. Este estudo procurou avaliar o grau de conhecimento e atitude quanto à epilepsia em trezentos professores, os quais responderam um questionário que quantifica o conhecimento, atitude e prática. Quase todos os professores já tinham ouvido falar sobre epilepsia e não discriminavam seus alunos. Alguns ainda acreditavam em contágio e poucos professores referiram objeções à presença de alunos com epilepsia em suas classes ou achavam que uma criança com epilepsia não poderia se tornar um bom professor. O conhecimento quanto às características clínicas ou procedimentos iniciais diante de uma crise epiléptica foi insatisfatório. Os resultados evidenciam que escolas médicas e médicos devem proporcionar um melhor conhecimento sobre epilepsia aos professores e campanhas educativas públicas devem também objetivar melhor esclarecimento sobre estas questões.

Objective:The study evaluated the trend of hospitalization for ischemic stroke (HIS) and its hospital mortality in Brazil over the last 15 years as well as the impact of the Hiperdia program in this scenario. Methods: An ecological study was designed with analytical approach and data collected in the Hospital Admission System on episodes of stroke, over the years 1998 to 2012. All data were stratified by sex and age, creating an indicator for HIS and proportion of hospital mortality. To estimate the trend of the data a polynomial curve fitting was created; and the Generalized Linear Model was applied to investigate the impact of Hiperdia on the endpoint HIS and hospital mortality. We adopted a 5% significance level to minimize an error type I. Results: We observed a reduction of HIS from 37.57/10 5 inhabitants in 1998 to 2001 to 10.33/10 5 inhabitants in 2002 to 2005, declining 73.64%. The reduction occurred in both sexes and for all age groups. The mortality rate of ischemic stroke also declined in Brazil since 2002, in both men and women, therefore in less than 3%; and only in the groups aged between 0 and 14 and above 80 years, we did not detect trend. Conclusion: Therefore, the decline of HIS temporally coincided with the implementation of Hiperdia in 2002 and this trend continues today.

Introduction: Depressive disorders can be defined as episodes of depressed mood or loss of interest and pleasure in nearly all activities. Depression is considered a major mental disorder in the elderly, and may be related to quality of sleep and living habits as well as being influenced by sociodemographic factors. Objective: To determine the prevalence of depression among the elderly in the north-east of Brazil, and the relationship between the condition and socio-demographic profile, quality of sleep and living habits. Method: An epidemiological cross-sectional study was performed of the elderly population of the urban area of Campina Grande, Paraiba. The dependent variable presence of depression and the independent variables sociodemographic aspects, sleep quality, and living habits were investigated. Estimates of the prevalence of the variables were obtained and association measured using Poisson Regression. A 5% significance level was adopted for the estimates. Results: The study included 168 elderly patients with a mean age of 72.3 (±7.8) years, most of whom, 122 (72.6%), were women. Depression was identified in 72 elderly persons (42.9%). Elderly women were twice as associated with depression (PR=2.26) as men. A subjective quality of sleep of very good (PR=0.34), medium/high risk of sleep disturbance (PR = 4.08), taking sleeping medications once or twice (PR=5.21) and three times or more (PR=8.69) a week, daytime dysfunction once or twice (PR=14.40) and three times or more (PR=27) a week and poor quality of sleep on the Pittsburgh index were associated with depression in bivariate analysis, although there was no relationship following multivariable adjustment. Conclusion: The prevalence of depression was high in the studied population, being noticeably more frequent among elderly woman. However, it was not possible to detect an association between depression and living habits and sleep quality.

Objective To assess sleep quality and its association with metabolic syndrome and its components. Methods This cross-sectional study was conducted from June 2011 to March 2012 at the Childhood Obesity Center, Campina Grande, Paraíba , Brazil, with 135 overweight or obese children and adolescents. Sleep quality was assessed by the Pittsburgh Sleep Quality Index. Metabolic syndrome diagnosis was based on abdominal circumference, blood pressure, glycemia, high density lipoprotein-cholesterol, and triglycerides. The data were treated by the software Statistical Package for the Social Sciences version 22.0 at a significance level of 5%. Results The prevalence of poor sleep quality or sleep disorder according to the Pittsburgh Sleep Quality Index was 40.7%, and females had higher mean global Pittsburgh Sleep Quality Index score. Metabolic syndrome prevalence was 63.0%. Females also had higher daytime dysfunction. Poor sleep quality was associated with high diastolic blood pressure (OR=2.6; p =0.015) and waist circumference (OR=3.17; p =0.024) after adjusting for sex and age. Conclusion Girls had higher global Pittsburgh Sleep Quality Index score, which was associated with daytime dysfunction. Poor sleep quality was a predictor of high diastolic blood pressure in the study sample.

It was found that obesity for women, and depression and cardiovascular dysfunction risking for men were associated with EDS in the elderly. The variable sex is a confusion condition for the association with sleepiness.

Introdução: Acidente vascular encefálico isquêmico (AVCI) é o comprometimento neurológico mais comum na população geral. Seu estudo permite conhecer sua dinâmica epidemiológica objetivando tomada de decisões em saúde pública. Objetivos: Traçar perfil temporal da ocorrência de AVCI e sua taxa de mortalidade hospitalar. Métodos: Utilizou-se um delineamento ecológico de série temporal nas Unidades Federativas do Nordeste brasileiro. Os dados foram coletados no Sistema de Informação Hospitalar sobre os episódios de AVCI, entre os anos de 1998 e 2010. Resultados: Observou-se grande redução na incidência de AVCI no período analisado, com redução de 31,33 casos/105 habitantes em média até 2002, para 11,4 casos/105, após esse período. A incidência de AVCI aumenta com a idade e não há diferença entre os sexos. A mortalidade hospitalar não mostrou alteração considerável no período. Conclusão: A incidência de AVCI no Nordeste do Brasil declinou a partir do ano de 2002, mantendo um novo paradigma.

EEG is a popular, low-cost examination used in neurologic and nonneurologic evaluations. Nevertheless, the diagnostic usefulness of EEG has some limitations, and it may increase medical costs. The manifestations of syncope may lead to misdiagnoses, and frequently, it is mislabeled as epilepsy. An EEG is usually obtained, yet some studies have suggested that EEGs have little value in diagnosing this condition. We aimed to determine the diagnostic usefulness of EEG in patients with syncope. We retrospectively examined EEG recordings of 10,408 patients. EEG findings were evaluated for all patients with a diagnosis of syncope (syncope, convulsive syncope, loss of consciousness, or sudden unexplained falls), including requests from neurologists and nonneurologists. EEGs were classified into (1) normal, (2) epileptiform discharges (spike/sharp waves), and (3) slow waves. The EEGs were separated according to gender and age. From 1,003 patients with the diagnosis of syncope, 899 (89.53%) were normal, 62 (6.18%) showed bilateral slow waves, 19 (1.89%) right slow waves, 18 (1.79%) epileptiform discharges, and 6 (0.6%) left slow waves. Epileptiform discharges only occurred among females. Left focal sharp waves were disclosed in 18 (50%), generalized discharges in 8 (44.4%), and right focal discharges in 1 (5.6%). Bilateral slow waves were more prevalent among adults. We conclude that EEG is not useful for evaluating the diagnosis of syncope because of its very low diagnostic yield. Patients with syncope must have a correct history and physical examination plus cardiovascular tests.

-The analysis of the temporal lobe seizures through video-EEG systems shows that they often consist of a sequence of clinical and EEG features which may suggest the localization and the lateralization of the epileptogenic lobe. We analyzed clinical and EEG features of 50 temporal lobe seizures which were separated in group 1 with 25 patients (related to mesial temporal sclerosis) and group 2 with 25 patients (other neocortical temporal lesions). Among the auras, the epigastric type was the most frequent and predominated in group 1. There were differences between the two groups, considering dystonic and tonic posturing and versive head and eye movements. Dystonic posturing was always contralateral to the ictal onset and was considered the most useful lateralizing clinical feature. Ictal speech, spitting and blinking automatisms, prolonged disorientation for place and a greatest percentage of postictal language preservation occurred in right temporal seizures. Postictal aphasia and global disorientation predominated in left temporal seizures. EEG was important for lateralizing the epileptogenic lobe, specially considering rhythmic ictal activity and postictal findings.KEY WORDS: temporal lobe epilepsy, complex partial seizures, video-EEG.Análise clínica e eletrencefalográfica de crises epilépticas temporais de origem mesial e lateral RESUMO -As crises epilépticas do lobo temporal tendem a seguir uma sequência previsível de eventos clínicos e eletrencefalográficos, cuja análise, preferencialmente através de sistemas de vídeo-EEG, sugere a localização e a lateralização do lobo epileptogênico. Para este estudo, foram analisadas 50 crises epilépticas do lobo temporal, do ponto de vista clínico e eletrencefalográfico, sendo 25 relacionadas a esclerose mesial (grupo 1) e 25 a patologias neocorticais (grupo 2). Auras abdominais foram as mais frequentes, predominando no grupo 1. Houve diferenças entre os dois grupos, quanto à instalação e duração da postura distônica, à postura tônica e à versão oculocefálica. Postura distônica unilateral foi o mais importante fenômeno clínico lateralizatório, sempre contralateral à área epileptogênica. Verbalização crítica, automatismo de cuspir, piscamento palpebral bilateral, desorientação espacial prolongada e maior percentual de preservação da linguagem no período pós-crítico foram relacionados a crises temporais direitas. Afasia pós-crítica e desorientação global, a crises temporais esquerdas. O EEG teve importante acurácia lateralizatória em ambos os grupos, especialmente quanto à atividade crítica rítmica e achados pós-críticos. PALAVRAS-CHAVE: epilepsia do lobo temporal, crises parciais complexas, vídeo-EEG.According to the International Classification of Epilepsies and Epileptic Syndromes 1 , these can be divided in partial, generalized, epilepsies and syndromes undetermined whether focal or generalized and special syndromes. Temporal lobe epilepsy (TLE) is responsible for 60% of all the partial epileptic seizures 2 and it has been extensively studied clinically, electr...
