Cerebellar degeneration and immune thrombocytopenic purpura associated with human immunodeficiency virus infection (HIV)

Cerebellar disorders associated with HIV infection are usually caused by opportunistic infections, central nervous system lymphoma, and toxic effects of medicines, nutritional and metabolic disorders, and cerebrovascular disease. We present an unusual association of cerebellar degeneration and immune thrombocytopenic purpura in a 28-years-old woman HIV infected. An autoimmune aetiology is likely.Universidade Federal de São Paulo, Escola Paulista Med, Dept Neurol & Neurosurg, São Paulo, BrazilUniversidade Federal de São Paulo, Escola Paulista Med, Dept Neurol & Neurosurg, São Paulo, BrazilWeb of Scienc

Síndrome de burnout e engajamento em profissionais de saúde: um estudo transversal

OBJECTIVE: To evaluate the frequency of severe burnout syndrome among critical care providers and to correlate it with work engagement. METHODS: A self-administered survey including the Maslach Burnout Inventory, Depression Anxiety and Stress Scales, and Gallup questionnaire was distributed. All analyses were stratified by setting (intensive care unit or step-down unit) and by professional group (nurses versus physicians versus physiotherapists). RESULTS: Between February 2017 and June 2017, 206 out of 325 invited professionals (63.4%) answered the questionnaires. Of these, 55 were physicians (26.7%), 88 were physiotherapists (42.7%) and 63 were nurses (30.6%). The frequency of severe burnout was 34.3% (27.9 - 41.4%), and no difference was found between professional groups or settings. The frequency of severe or very severe cases of depression, anxiety or stress was 12.9%, 11.4% and 10.5%, respectively. The median (interquartile range) score observed on the Gallup questionnaire was 41 (34 - 48), and no differences were found between professional groups or settings. There was a negative correlation between burnout and work engagement (r = -0.148; p = 0.035). CONCLUSION: There is a high frequency of severe burnout among critical care providers working in the intensive care unit and step-down unit. There was a negative correlation between burnout and work engagement

Clinical features of dystonia in atypical parkinsonism Características clínicas da distonia no parkinsonismo atípico

BACKGROUND: The association between Dystonia and Parkinson's disease (PD) has been well described especially for foot and hand dystonia. There is however few data on dystonic postures in patients with atypical parkinsonism. OBJECTIVE: To evaluate the frequency and pattern of dystonia in a group of patients with atypical parkinsonism (multiple system atrophy - MSA, progressive supranuclear palsy - PSP, and corticobasal degeneration - CBD) and to investigate whether dystonia could be the first presenting symptom at disease onset in those patients. METHOD: A total of 38 medical charts were reviewed (n=23/MSA group; n=7/CBD group; n=8/PSP group) and data values were described as means/standard deviations. The variables evaluated were sex, age at onset, disease duration, first symptom, clinical features of dystonia and other neurological signs, response to levodopatherapy, Hoehn&Yahr scale >3 after three years of disease, and magnetic resonance imaging findings. RESULTS: The overall frequency of dystonia in our sample was 50% with 30.4% (n=7) in the MSA group, 62.5% (n=5) in the PSP group, and 100% (n=8) in the CBD group. In none of these patients, dystonia was the first complaint. Several types of dystonia were found: camptocormia, retrocollis, anterocollis, blepharoespasm, oromandibular, and foot/hand dystonia. CONCLUSION: In our series, dystonia was a common feature in atypical parkinsonism (overall frequency of 50%) and it was part of the natural history although not the first symptom at disease onset. Neuroimaging abnormalities are not necessarily related to focal dystonia, and levodopa therapy did not influence the pattern of dystonia in our group of patients.<br>INTRODUÇÃO: A associação de distonia e doença de Parkinson (DP) já foi bem estabelecida, principalmente para distonia focal em pé ou mão. Entretanto, há poucos dados quanto a distonia em pacientes com parkinsonismo atípico. OBJETIVO: Avaliar a freqüência e o padrão da distonia em um grupo de pacientes com parkisnonismo atípico (atrofia de múltiplos sistemas - AMS; paralisia supranuclear progressiva - PSP; degeneração corticobasal - DCB) e investigar se a distonia pode ser a manifestação inicial neste grupo. MÉTODO: Um total de 38 prontuários médicos foi revisado (n=23/grupo AMS; n=8/grupo PSP; n=7/grupo PSP) e os dados foram apresentados em médias/desvios padrões. As variaveis avaliadas foram: sexo, idade de início, duração da doença, primeiro sintoma, características clínicas da distonia e outros sinais neurológicos, resposta ao tratamento com levodopa, escala de Hoehn & Yahr >3 em 3 anos de doença, e achados de ressonância magnética. RESULTADOS: A frequência total de distonia em nosso grupo foi 50%, sendo 30,4% (n=7) no grupo AMS, 62.5% (n=5) no grupo PSP e 100% (n=8) no grupo DCB. Em nenhum dos pacientes, distonia foi o primeiro sintoma. Várias apresentações de distonia foram observadas: camptocormia, anterocólis, retrocólis, distonia oromandibular, em pé e mão. CONCLUSÃO: Em nossa série, distonia foi uma característica comum em pacientes com parkinsonismo atípico (freqüência de 50%) e fez parte da história natural em todos os grupos, embora não tenha sido o sintoma inicial em nenhum deles. Anormalidades no exame de neuroimagem não necessariamente estão relacionadas a distonia focal, e o tratamento com levodopa não influenciou o padrão da distonia em nosso grupo de pacientes
