Reflexões a respeito da educação a distância: a visão de professores em formação continuada

The study aimed to analyze the vision of teachers in conducting a continuing education course in level of expertise in the field of special education, focusing on Global Development Disorders, through the modality of distance education. The current study was provided by the Network Program São Paulo Teacher Training - REDEFOR in partnership with Universidade Estadual Paulista-UNESP, for teachers of the state of São Paulo. The survey went through some steps, namely: a) literature review a brief history of Distance Education in Brazil and in the world thus seeking to understand their development to the present day, including legislation that regulates; b) study and survey of potential and limiting factors for distance education in teacher training. Was observed of initial and continuing teacher education in the distance mode, focusing on education and training policies implemented by the state of São Paulo, in recent years; c) data collection with 33 teachers in the continuing education process, e-mail and performed with the use of Google Drive tool that enabled the creation of online search form; d) organization, analysis and interpretation of data and its consequences. Through the results it observed that distance education is considered a favorable mode of education for the continuing education of teachers. The course was offered via Moodle and tools were considered easy to assimilate and elaborate activities in general, favored the construction of knowledge, and some questioned for its effectiveness. It follows therefore, that distance education provides continuing education for teachers, but it is necessary in the preparation of these courses is taken into consideration the tools and resources available in their construction, contributing to a dynamic and interactive model between all participants in which the exchange of experiences, questions, doubts, can effectively contribute to the construction of knowledge and possible developments in..

Encefalite anti-receptor N-metil-D-aspartato na infância

OBJETIVO: Discutir o diagnóstico diferencial das encefalites além daquelas de etiologia infecciosa, e alertar os pediatras para a possibilidade do diagnóstico de encefalite anti-receptor N-metil-D-aspartato (rNMDA) na população pediátrica, destacando suas principais características clínicas. DESCRIÇÃO: Três pacientes apresentaram-se com uma síndrome neuropsiquiátrica inicial seguida de encefalopatia e transtornos de movimento. As características neuropsiquiátricas iniciais se desenvolveram ao longo de dias ou semanas, com mudanças comportamentais, ansiedade, confusão mental e regressão da fala. Em seguida, os pacientes evoluíram com distúrbios de movimento, caracterizados por coreoatetose ou distonia, acometendo a região orofacial e os membros. Após a exclusão das principais causas de encefalite, foram identificados anticorpos anti-rNMDA no soro e no líquido cefalorraquidiano. Não foram detectadas neoplasias durante a investigação etiológica. Os pacientes foram submetidos a imunossupressão, e dois deles tiveram uma recuperação neurológica completa. Um deles ainda apresenta uma postura distônica leve em um dos membros. COMENTÁRIOS: Os sinais clínicos de encefalite anti-rNMDA em crianças são semelhantes aos anteriormente descritos em adultos. Tumores geralmente não são detectados nessa idade. O diagnóstico de encefalite anti-rNMDA deve ser abordado após a exclusão de outras causas de encefalite na infância, como as de origem infecciosa. Pediatras devem estar atentos a essa condição autoimune passível de tratamento.

Stigma and higher rates of psychiatric re-hospitalization: Sao Paulo public mental health system

Objective: The aim of this study was to assess re-hospitalization rates of individuals with psychosis and bipolar disorder and to study determinants of readmission. Methods: Prospective observational study, conducted in Sao Paulo, Brazil. One hundred-sixty-nine individuals with bipolar and psychotic disorder in need of hospitalization in the public mental health system were followed for 12 months after discharge. Their families were contacted by telephone and interviews were conducted at 1, 2, 6 and 12 months post-discharge to evaluate readmission rates and factors related. Results: One-year re-hospitalization rate was of 42.6%. Physical restraint during hospital stay was a risk factor (OR = 5.4-10.5) for readmission in most models. Not attending consultations after discharge was related to the 12-month point readmission (OR = 8.5, 95% CI 2.3-31.2) and to the survival model (OR = 3.2, 95% CI 1.5-7.2). Number of previous admissions was a risk factor for the survival model (OR = 6.6-11.9). Family's agreement with permanent hospitalization of individuals with mental illness was the predictor associated to readmission in all models (OR = 3.5-10.9) and resulted in shorter survival time to readmission; those readmitted were stereotyped as dangerous and unhealthy. Conclusions: Family's stigma towards mental illness might contribute to the increase in readmission rates of their relatives with psychiatric disorders. More studies should be conducted to depict mechanisms by which stigma increases re-hospitalization rates.

Language impairment in Huntington's disease

Language alterations in Huntington's disease (HD) are reported, but their nature and correlation with other cognitive impairments are still under investigation. This study aimed to characterize the language disturbances in HD and to correlate them to motor and cognitive aspects of the disease. We studied 23 HD patients and 23 controls, matched for age and schooling, using the Boston Diagnostic Aphasia Examination, Boston Naming Test, the Token Test, Animal fluency, Action fluency, FAS-COWA, the Symbol Digit Modalities Test, the Stroop Test and the Hooper Visual Organization Test (HVOT). HD patients performed poorer in verbal fluency (p<0.0001), oral comprehension (p<0.0001), repetition (p<0.0001), oral agility (p<0.0001), reading comprehension (p=0.034) and narrative writing (p<0.0001). There was a moderate correlation between the Expressive Component and Language Competency Indexes and the HVOT (r=0.519, p=0.011 and r=0.450, p=0.031, respectively). Language alterations in HD seem to reflect a derangement in both frontostriatal and frontotemporal regions.

Atividade muscular da mastigação na anquilose temporomandibular

Purpose: due to the presence of major masticatory dysfunction in patients with temporomandibular joint (TMJ) ankylosis, this study analyzed mouth opening and EMG activity of masticatory muscles in order to detect changes in these parameters after surgical release of mandible ankylosis. Method: in 7 patients with temporomandibular ankylosis, between 7 and 30 years (median = 9 years), the distance was measured as interincisal maximum active (DIMA) and we recorded the electromyographic activity (EMG) of masseter and temporal muscles during voluntary isometric contraction (VIC) and chewing, comparing the data before and after surgery using the Wilcoxon test. Results: higher values were observed for DIMA after surgery (p=0.0277), the asymmetry index showed no difference between the two evaluated periods for both studied muscles, the values of the EMG during VIC decreased after surgery for the right (p=0.0179) and left (p=0.0179) masseter but not for the temporal muscle, there were no changes in EMG values for the studied muscles during mastication. Conclusion: the surgical release of TMJ ankylosis resulted in an increase of mouth opening and decreased amplitude of action potentials generated during maximum isometric voluntary contraction of the masseter muscle on both sides, this did not change the asymmetry index of the masseter and temporal as well as the electromyographic activity of the temporal muscle bilaterally during isometric contraction and masseter and temporal muscles during mastication.

Risk factors for swallowing dysfunction in stroke patients

CONTEXT: Stroke is a frequent cause of dysphagia. OBJECTIVE: To evaluate in a tertiary care hospital the prevalence of swallowing dysfunction in stroke patients, to analyze factors associated with the dysfunction and to relate swallowing dysfunction to mortality 3 months after the stroke. METHODS: Clinical evaluation of deglutition was performed in 212 consecutive patients with a medical and radiologic diagnosis of stroke. The occurrence of death was determined 3 months after the stroke. RESULTS: It was observed that 63% of the patients had swallowing dysfunction. The variables gender and specific location of the lesion were not associated with the presence or absence of swallowing dysfunction. The patients with swallowing dysfunction had more frequently a previous stroke, had a stroke in the left hemisphere, motor and/or sensitivity alterations, difficulty in oral comprehension, alteration of oral expression, alteration of the level of consciousness, complications such as fever and pneumonia, high indexes on the Rankin scale, and low indexes on the Barthel scale. These patients had a higher mortality rate. CONCLUSIONS: Swallowing evaluation should be done in all patients with stroke, since swallowing dysfunction is associated with complications and an increased risk of death.

Esophageal contractions, bolus transit and perception of transit after swallows of liquid and solid boluses in normal subjects

CONTEXT: Esophageal dysphagia is the sensation that the ingested material has a slow transit or blockage in its normal passage to the stomach. It is not always associated with motility or transit alterations. OBJECTIVES: To evaluate in normal volunteers the possibility of perception of bolus transit through the esophagus after swallows of liquid and solid boluses, the differences in esophageal contraction and transit with these boluses, and the association of transit perception with alteration of esophageal contraction and/or transit. METHODS: The investigation included 11 asymptomatic volunteers, 4 men and 7 women aged 19-58 years. The subjects were evaluated in the sitting position. They performed swallows of the same volume of liquid (isotonic drink) and solid (macaroni) boluses in a random order and in duplicate. After each swallow they were asked about the sensation of bolus passage through the esophagus. Contractions and transit were evaluated simultaneously by solid state manometry and impedance. RESULTS: Perception of bolus transit occurred only with the solid bolus. The amplitude and area under the curve of contractions were higher with swallows of the solid bolus than with swallows of the liquid bolus. The difference was more evident in swallows with no perception of transit (n = 12) than in swallows with perception (n = 10). The total bolus transit time was longer for the solid bolus than for the liquid bolus only with swallows followed by no perception of transit. CONCLUSION: The results suggest that the perception of esophageal transit may be the consequence of inadequate adaptation of esophageal transit and contraction to the characteristics of the swallowed bolus.

Perfil clínico e demográfico de anestesiologistas usuários de álcool e outras drogas atendidos em um serviço pioneiro no Brasil

JUSTIFICATIVA E OBJETIVOS: Anestesiologistas são os mais representados em serviços de atendimento a médicos com transtornos por uso de substâncias psicoativas. O objetivo deste trabalho é apresentar um estudo descritivo sobre o perfil clínico e sociodemográfico de uma amostra de anestesiologistas dependentes químicos atendidos em um serviço de referência, bem como elencar comorbidades psiquiátricas, drogas frequentemente utilizadas e repercussões psicossociais e profissionais do consumo. MÉTODO: Realizou-se estudo transversal, prospectivo, tendo sido aplicadas entrevistas estruturadas para diagnóstico de transtornos mentais e transtornos por uso de substâncias psicoativas, com base na Classificação Internacional de Doenças - Versão 10 - e questionário sócio-ocupacional, aplicados por dois pesquisadores treinados. RESULTADOS: Cinquenta e sete anestesiologistas foram entrevistados, em sua maioria do sexo masculino (77,2%), idade média de 36,1 anos (DP = 8,5). Observou-se uma alta prevalência de uso de opioides (59,6%), benzodiazepínicos (35,1%) e álcool (35,1%). Usuários de opioides procuraram tratamento mais precocemente comparado aos não usuários desta substância e, geralmente, sob influência da pressão de colegas ou do conselho regional de medicina. O uso de drogas como automedicação foi elevado dentro deste subgrupo. CONCLUSÕES: Anestesiologistas podem apresentar um perfil distinto de risco de uso de opioides. O padrão de início de consumo, associado aos anos de residência médica ou aos primeiros anos da prática médica, reforça a hipótese de dependência de opioides como problema ocupacional entre anestesiologistas.

Influência de tratamentos para enxaqueca na qualidade de vida: revisão integrativa de literatura

Este estudo objetivou identificar o impacto dos principais tratamentos para a enxaqueca na qualidade de vida (QV) de pessoas acometidas e os instrumentos utilizados para a avaliação da QV. Trata-se de uma revisão integrativa de literatura em que foram utilizadas as bases de dados PubMed, BIREME e The Cochrane Library e selecionados artigos entre 2000 a 2009. Foram eleitos 42 artigos para análise e leitura na íntegra. Os artigos foram classificados em três categorias: tratamentos farmacológicos para a crise, tratamentos farmacológicos profiláticos e tratamentos alternativos para enxaqueca. Na maioria dos estudos os instrumentos utilizados para avaliar a QV eram validados e os mais comumente utilizados foram o Medical Outcomes Study Questionaire 36-Item Short Form Health Survey (SF 36), o Migraine-Specific Quality of Life Questionnaire e o Migraine Disability Assessment. Conclui-se que, de uma maneira geral, os tratamentos parecem refletir positivamente na QV dos sujeitos com enxaqueca.
