Durante 27 anos, o diagnóstico clínico da doença de Alzheimer foi baseado nos critérios feitos, em 1984, pela National Institute of Neurological and Communicative Disorders and Strokes (NINCDS) e pelo Alzheimer's Disease and Related Disorders Association (ADRDA). Contudo, com o passar dos anos, os avanços científicos permitiram melhor compreensão da sua fisiopatologia, bem como melhor entendimento sobre as outras formas de demência-que culminaram na necessidade de revisão dos antigos critérios. Por isso, em 2011 foram publicados quatro artigos com novas recomendações da NINCDS-ADRDA. As principais mudanças nas novas diretrizes envolvem a identificação de estágios não demenciais para doença e a incorporação dos biomarcadores.
This manuscript reports a case of intestinal toxemia botulism in an adult with recently diagnosed metastatic colon cancer in whom botulism symptoms began 23 days after hospital admission. Representing the rarest form of botulism presentation in clinical practice, this infectious disease may have developed due to a cluster of predisposing factors that favored Clostridium botulinum colonization and the endogenous production of neurotoxins, among which are previous use of broad-spectrum antibiotics and colon changes related to the development of the neoplasia. This case highlights the importance of considering intestinal toxemia botulism in the differential diagnosis of a patient presenting with symmetrical descending flaccid paralysis, since immediate treatment with botulinum antitoxin may improve clinical outcomes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
