ABSTRACT
OBJETIVO: Verificar a ocorrência dos efeitos adversos relacionados ao uso da toxina botulínica na face, por meio de revisão sistemática, usando meta-análise. MÉTODOS: Foi realizada pesquisa eletrônica de artigos publicados no MEDLINE e Cochrane Library até setembro de 2007. A ocorrência dos efeitos adversos foi verificada pela freqüência relativa para os relatos de casos e do risco relativo para os estudos randomizados. A heterogeneidade foi avaliada pelo teste Q e pelo índice I². Foi utilizado o teste de significância de Egger para identificar viés de publicação e a análise de sensibilidade para verificar o efeito dos viéses de publicação. RESULTADOS: Oito estudos randomizados e treze relatos de casos preencheram os critérios de inclusão. Na revisão sistemática dos relatos de casos, 1.003 pacientes foram estudados, dos quais 182 (18,14 por cento) apresentaram efeitos adversos. O efeito adverso mais freqüente foi a ptose palpebral ocorrendo em 34 (3,39 por cento) pacientes dos relatos de casos. Na meta-análise dos estudos randomizados, o risco relativo global para os efeitos adversos como cefaléia, ptose palpebral, reação local e infecção foi 1,07, 3,25, 0,99 e 0,94, respectivamente. Para todas as comparações, o valor de P foi maior que 0,05. CONCLUSÃO: O efeito adverso mais freqüente e que apresentou o maior risco relativo relacionado ao uso da toxina botulínica na face foi a ptose palpebral. A padronização dos efeitos adversos relatados é necessária a fim de melhor estabelecer as características dos mesmos.
PURPOSE: To estimate the occurrence of adverse effects associated with the use of botulinum toxin by performing a systematic review and meta-analysis. METHODS: A systematic literature search of MEDLINE and Cochrane Library was conducted until September 2007. The occurrence of the adverse effects was estimated of the relative frequency for case report and of the relative risk for randomized trials. Heterogeneity was evaluated with the Q test and I² index. Egger's significance test was used to identify the publication bias. Sensitivity analysis was performed to evaluate the effect of the publication biases. RESULTS: Eight randomized trials and thirteen case reports filled the inclusion criteria. In the systematic review of case reports, 1,003 subjects were studied and 182 (18.14 percent) showed adverse effects. Eyelid ptosis was the most frequent adverse effect, presenting in 34 (3.39 percent) patients of the case reports. In the meta-analysis of randomized trials, the overall relative risk for adverse effects as headache, eyelid ptosis, local reaction and infection was respectively: 1.07, 3.25, 0.99 and 0.94. For all comparisons, P values were greater than 0.05. CONCLUSION: Ptosis was the most frequent adverse effect and showed the higher relative risk associated with botulinum toxin. It is necessary to perform a pattern of adverse effects related for better understanding the relationship between adverse effects and use of botulinum toxin.

Objective: The aim of the present study is to investigate whether there are geographic differences in the etiology of parkinsonism (PA). Background: 72 percent of patients with PA evaluated at movement disorders clinics in the Northern Hemisphere are diagnosed with Parkinson's disease (PD). Data regarding other regions are not available. Methods: We reviewed the charts of all patients with PA seen at the Federal University of Minas Gerais Movement Disorders Clinic from July 1993 through October 1995. PA was diagnosed by the presence of at least two of the following: rest tremor, bradykinesia, rigidity, and postural instability. The different etiologies were diagnosed based on standard clinical criteria Results: During the period of the study, PA was recognized in 338 subjects. The following clinical diagnoses were made: PD (68.9 percent), drug-induced PA (DIP) (13,3 percent), vascular PA (4.7 percent), progressive supranuclear palsy (PSP) (2 percent), multiple system atrophy (MSA) (1.8 percent), others (9.7 percent). Cinnarizine, haloperidol and flunarizine were the commonest drugs related to DIP. Conclusions: Similarly to other studies, PD accounts for about 70 percent of PA patients. However, there are differences between our results and previous series. DIP is much more common in the present series. This may be accounted for a more liberal use of antidopaminergic drugs in our environment, especially Calcium channel blockers. The lower frequency of MSA and PSP in our study may reflect a short follow-up, since many patients initially diagnosed with PD later are found to have Parkinson-plus syndromes.
