RESUMEN

Pharmacological treatments for mild cognitive impairment (MCI), are lacking, and alternative approaches have been implemented, including cognitive training (CT). OBJECTIVE: To determine the impact of CT on cognitive and quality of life measures in patients with Parkinson's disease (PD) who were seen a hospital neurorehabilitation program. METHODS: Thirty-nine individuals with MCI-PD, according to the Movement Disorder Society, were randomly distributed into two groups: experimental and control group, matched for demographic and clinical characteristics. Both groups were assessed for cognition and quality of life at the beginning of the study and at the end of the intervention protocol. The following instruments were used to assess cognition and quality of life: Addenbrooke's Cognitive Examination III, Digit Span, Trail Making Test (TMT, A and B) and Parkinson disease quality of life questionnaire. The experimental group (EG) engaged in CT, whereas the control group (CG) underwent activities of the general rehabilitation program. RESULTS: No baseline evaluation differences were found. Intergroup analysis showed differences in measures, such as total score (1.977, p=0.0480) and visuospatial domain (-2.636, p=0.0084) of the ACE-III, with the EG performing better, in addition to better performance in TMT-B mistakes (-1.928, p=0.0439). Intragroup analysis revealed that the EG showed significant improvement in almost all the cognitive variables, well as in self-reported quality of life (total score and mobility, activities of daily living, body discomfort dimensions). CONCLUSIONS: Engagement in cognitive activities was associated with better cognitive abilities in PD-MCI. Future studies should consider the long-term effect of this type of intervention and impact on functional activities.

A falta de evidência de tratamentos farmacológicos, especificamente para pacientes com comprometimento cognitivo leve na doença de Parkinson (CCL-DP), leva à implementação de abordagens alternativas, incluindo a reabilitação cognitiva. OBJETIVO: Determinar o impacto do treino cognitivo (TC) em medidas cognitivas e da qualidade de vida em pacientes com DP, que participavam de um programa de reabilitação neurológica hospitalar. MÉTODOS: Total de 39 indivíduos com CCL-DP, de acordo com a Sociedade de Distúrbios do Movimento, foram distribuídos aleatoriamente em dois grupos: experimental e controle, pareados por características demográficas e clínicas. Ambos os grupos foram avaliados quanto à cognição e qualidade de vida no início do estudo e ao final do protocolo de intervenção. Os seguintes instrumentos foram utilizados para avaliar a cognição e a qualidade de vida: Exame Cognitivo III de Addenbrooke, teste de dígitos, TMT (A e B) e questionário de qualidade de vida da doença de Parkinson. O grupo experimental foi submetido ao treino cognitivo, ao passo que o grupo controle passou por atividades do programa de reabilitação. RESULTADOS: Não foram encontradas diferenças na avaliação basal. A análise intergrupo mostrou diferenças em medidas, como escore total (1,977, p=0,0480) e domínio visuoespacial (-2,636, p=0,0084) da ACE-III, tendo o grupo experimental melhor desempenho, além de desempenho superior em TMT-B erros (-1,928, p=0,0439). A análise intragrupo revelou que o grupo experimental mostrou melhora significativa em quase todas as variáveis cognitivas, assim como na percepção de qualidade de vida (escore total e dimensões de mobilidade, atividades da vida diária e desconforto corporal). CONCLUSÕES: O envolvimento em atividades cognitivas foi associado a melhores habilidades cognitivas em pacientes com CCL-DP. Estudos futuros devem considerar o efeito a longo prazo desse tipo de intervenção e o impacto nas atividades funcionais.

RESUMEN

PURPOSE: Comorbidity of celiac disease with demyelinating diseases of the central nervous system has been reported since the 1960s. The objective of this study was to determine the serological prevalence of celiac disease in the largest series of patients diagnosed with multiple sclerosis, neuromyelitis optica, or myelitis. METHODS: A prevalence study was conducted with patients evaluated at Sarah Network of Rehabilitation Hospitals between March 2012 and September 2013. They were previously diagnosed with multiple sclerosis, neuromyelitis optica, or idiopathic myelitis. The serum levels of antibodies against tissue transglutaminase and endomysium were assessed. RESULTS: Of the 379 patients evaluated, 249 (65.70%) were diagnosed with multiple sclerosis, 37 (9.56%) with neuromyelitis optica, and 96 (24.54%) with idiopathic myelitis. Two patients (0.53%), one with multiple sclerosis and other with myelitis, tested positive for both antibodies. CONCLUSION: Our study do not confirm the relationship between celiac serological antibodies with multiple sclerosis, neuromyelitis optica and inflammatory myelitis of an unknown etiology.

RESUMEN

OBJECTIVES: To determine if there are evidences of a causal relation between patent foramen ovale (PFO) x cryptogenic ischemic stroke (IS) in the young population and to analyze this relation in terms of causal criteria. METHODS: A total of 168 young patients with IS was retrospectively evaluated and divided into two groups: cryptogenic and with a defined cause. As a routine procedure, the patients underwent investigation of the PFO by means of transesophageal echocardiogram and/or transcranial Doppler sonography, both of them associated with the bubble test. Multivariate analysis was performed after demonstration of univariate statistical association between PFO x IS. RESULTS: After multivariate analysis, the association between PFO x cryptogenic IS was still statistically significant with odds ratio (adjusted OR = 3.3; 95% CI: 1.5-7.4). The total number of cerebral lesions also presented a significant association with cryptogenic IS (adjusted OR = 0.4; 95% CI: 0.2-0.9). The association between PFO and cryptogenic IS met all the causality criteria. CONCLUSION: The causal relation between PFO and cryptogenic IS in the young population is highly probable. This fact should be considered in the therapeutic decision.

RESUMEN

OBJETIVOS: Determinar se há evidências de uma relação causal entre forame oval patente (FOP) e acidente vascular cerebral isquêmico (AVCI) criptogênico em jovens. Analisar essa relação à luz dos critérios de causalidade. MÉTODOS: Avaliaram-se, retrospectivamente, 168 pacientes jovens com AVCI, divididos em dois grupos: criptogênico e de causa definida. Como parte da rotina, os pacientes foram submetidos a pesquisa de FOP por ecocardiograma transesofágico e/ou Doppler transcraniano, ambos associados ao teste de bolhas. Demonstrada a associação estatística univariada entre FOP e AVCI, procedeu-se a análise multivariada. RESULTADOS: Após análise multivariada, a associação FOP e AVCI criptogênico mostrou-se ainda estatisticamente significante, com razão de chance (RCajustada de 3,3 (IC95 por cento 1,5-7,4). O número total de lesões no encéfalo também apresentou associação significativa com o AVCI criptogênico (RCajustada= 0,4 IC95 por cento 0,2-0,9). A associação FOP e AVCI criptogênico satisfez todos os critérios de causalidade. CONCLUSÃO: A relação causal entre o FOP e o AVCI criptogênico em jovens é altamente provável. Esse fato deve ser considerado na decisão terapêutica.

RESUMEN

A multiple sclerosis-like syndrome, also called lupoid sclerosis for having some lupus characteristics, has been described in a few reports. Recently, antiphospholipid antibodies have been demonstrated in patients with this syndrome, suggesting that they can participate in the etiopathogenic process, which can have therapeutic implications. We report the case of a patient previously diagnosed with multiple sclerosis who later presented with ANA positivity and antiphospholipid antibodies, livedo reticularis, and deep venous thrombosis, leading her to be characterized as having lupoid sclerosis. The patient was anticoagulated. Antiphospholipid antibodies may be involved in the pathogenesis of lupoid sclerosis.

RESUMEN

Estima-se que 40 por cento dos acidentes vasculares cerebrais isquêmicos (AVC) sejam classificados como criptogênicos. Essa cifra costuma ser maior nos pacientes jovens. A embolia paradoxal, cujo forame oval patente (FOP) é o principal exemplo, pode ser responsável por uma parcela desses casos. Entre janeiro de 2004 e novembro de 2004, 168 pacientes com diagnóstico de AVCI, entre 15 e 45 anos de idade, admitidos em unidades da Rede Sarah de hospitais foram admitidos, além da avaliação de rotina, a pesquisa de FOP com ecodopplercardiograma transesofágico e/ou Doppler transcraniano, ambos associados ao teste de bolhas.Usando a combinação dos dois métodos a prevalência da FOP em toda a amostra foi de 28 por cento (IC95 por cento 21,3-35,4).Nos pacientes com AVCI criptogênico essa prevalência sobe para 40 por cento e no grupo com etiologia definida foi de apenas 15 por cento, configurando uma razão de chances de 3,7 (IC 95 por cento 1,8-7,9). Esses resultados apontam para a necessidade de se considerar a possibilidade de embolia paradoxal na etiologia do AVCI criptogênico em pacientes jovens.
