ABSTRACT
Cervical dystonia (CD) is a prevalent and incapacitating movement disorder which needs a thorough clinical evaluation of every patient to better tailor treatment strategies. In Brazil, there are no validated CD scales that measure the burden of dystonia. The aim of our study was to translate and adapt the Toronto Western Spasmodic Torticollis Rating Scale (TWSTRS) to Brazilian Portuguese. After translation and back-translation according to international methods, a pre-test was carried out with 30 patients. Patients under 8 years of formal schooling had severe difficulty in understanding the whole scale. The scale went through a remodeling process, without loss of its conceptual and semantic properties. The new scale was tested in 15 patients, with good understanding scores. We are now in the process of validation of the adapted scale.
Distonia cervical (DC) é um transtorno de movimento prevalente e incapacitante, sendo uma avaliação global e consistente de cada paciente necessária para a melhor intervenção diagnóstica e terapêutica. No Brasil, não há escalas validadas para avaliar o impacto da DC. O objetivo deste trabalho foi traduzir e adaptar uma escala mundialmente conhecida e usada, a Toronto Western Spasmodic Torticollis Rating Scale (TWSTRS) para o português. Após a tradução e retro-tradução da escala segundo as normas e critérios internacionais, realizamos o pré-teste com 30 pacientes, sendo que o completo entendimento da escala ficou prejudicado nos pacientes com escolaridade abaixo de 8 anos. Tornou-se necessária a re-adaptação da escala, com modificação de alguns elementos, tentando manter-se sua integridade conceitual e semântica. Após pré-teste adicional com 15 pacientes, verificou-se que a escala foi completamente entendida por praticamente todos os pacientes. A validação da escala está em andamento.

Persistent pain is a frequent health problem in the elderly. Its prevalence ranges from 45 percent to 80 percent. Chronic diseases, such as depression, cardiovascular disease, cancer and osteoporosis have a higher prevalence in aged individuals and increase the risk of developing chronic pain. The presence of pain is known to be associated with sleep disorders in these patients, as well as functional impairment, decreased sociability and greater use of the health system, with consequent increase in costs. Alzheimer's disease patients seem to have a normal pain discriminative capacity and they may probably have weaker emotional and affective experience of pain when compared to other types of dementia. Many patients have language deficits and thus cannot properly describe its characteristics. In more advanced cases, it becomes even difficult to determine whether pain is present or not. Therefore, the evaluation of these patients should be performed in a systematic way. There are three ways to measure the presence of pain: by direct questioning (self-report), by direct behavioral observation and by interviews with caregivers or informants. In recent years, many pain scales and questionnaires have been published and validated specifically for the elderly population. Some are specific to patients with cognitive decline, allowing pain evaluation to be conducted in a structured and reproducible way. The next step is to determine the type of painful syndrome and discuss the bases of the pharmacological management, the use of multiple medications and the presence of comorbidities demand the use of smaller doses and impose contra-indications against some drug classes. A multiprofessional approach is the rule in the management of these patients.
Dor persistente é um problema de saúde frequente no idoso e sua prevalência varia de 45 a 80 por cento. Doenças crônicas, como depressão, distúrbios cardiovasculares, câncer e osteoporose tem alta prevalência em indivíduos idosos e aumentam o risco de desenvolver dor crônica. Nestes indivíduos, a presença de dor está associada a distúrbios do sono, prejuízo funcional, diminuição da sociabilidade e maior procura dos serviços de saúde, com o consequente aumento dos custos de saúde. Pacientes com Alzheimer têm uma capacidade discriminativa dolorosa normal e uma experiência afetiva e emocional da dor mais atenuada quando comparados com outros tipos de demência. Muitos pacientes têm déficits de linguagem e não podem descrever adequadamente as características de sua dor. Em casos avançados, torna-se difícil determinar se a dor está realmente presente ou não. Desta forma, a avaliação destes doentes deve ser realizada de forma sistemática. Há três formas de se avaliar a dor: questionários diretos, observação direta do comportamento ou entrevistas diretas com os cuidadores ou informantes. Nos últimos anos muitas escalas e questionários para dor foram publicados e validados especificamente para a população idosa. Alguns são específicos para pacientes com declínio cognitivo, permitindo que a evolução da dor possa ser conduzida de uma forma estruturada e reprodutível. O passo seguinte é se determinar o tipo de síndrome dolorosa e se discutir as bases do manejo farmacológico. O uso de múltiplas medicações e a presença de comorbidades exige o uso de pequenas doses e impõem contra-indicações para algumas classes de drogas. A abordagem multidisciplinar é a regra no seguimento a longo prazo destes doentes.

According to the concepts of cognitive neuropsychology, there are two principal routes of reading processing: a lexical route, in which global reading of words occurs and a phonological route, responsible for the conversion of the graphemes into their respective phonemes. In the present study, functional magnetic resonance imaging (fMRI) was used to investigate the patterns of cerebral activation in lexical and phonological reading by 13 healthy women with a formal educational level greater than 11 years. Participants were submitted to a silent reading task containing three types of stimuli: real words (irregular and foreign words), nonwords and illegitimate graphic stimuli. An increased number of activated voxels were identified by fMRI in the word reading (lexical processing) than in the nonword reading (phonological processing) task. In word reading, activation was greater than for nonwords in the following areas: superior, middle and inferior frontal gyri, and bilateral superior temporal gyrus, right cerebellum and the left precentral gyrus, as indicated by fMRI. In the reading of nonwords, the activation was predominant in the right cerebellum and in the left superior temporal gyrus. The results of the present study suggest the existence of differences in the patterns of cerebral activation during lexical and phonological reading, with greater involvement of the right hemisphere in reading words than nonwords.

Chorea may occur as a neurological manifestation of systemic lupus erythematosus and is often associated with detection of antiphospholipid antibodies. No evidence of chorea as a sign of lupus activity has been established. We describe a patient with systemic lupus erythematosus associated with antiphospholipid antibodies who developed chorea, which has been considered a sign of lupus activity.
