Guillain-Barré syndrome: advances and future perspectives

The first case of Guillain-Barré syndrome was described in 1916. Since then, knowledge about the pathophysiology and immunogenesis of this acquired inflammatory polyradiculoneuropathy has been growing steadily, especially after the advent of nerve conduction studies and the discovery of pathogenic autoantibodies. In the present study, we conducted a review of the main information available in the literature to date about the syndrome, including its diagnosis and management

Guillain-Barré syndrome associated with the Zika virus outbreak in Brazil

ABSTRACT Zika virus (ZIKV) is now considered an emerging flavivirosis, with a first large outbreak registered in the Yap Islands in 2007. In 2013, a new outbreak was reported in the French Polynesia, with associated cases of neurological complications including Guillain-Barré syndrome (GBS). The incidence of GBS has increased in Brazil since 2015, what is speculated to be secondary to the ZIKV infection outbreak. The gold-standard test for detection of acute ZIKV infection is the polymerase-chain reaction technique, an essay largely unavailable in Brazil. The diagnosis of GBS is feasible even in resource-limited areas using the criteria proposed by the GBS Classification Group, which is based solely on clinical grounds. Further understanding on the relationship of ZIKV with neurological complications is a research urgency

Polineuropatia devida ao óxido de etileno registro de caso com estudo clínico, eletrofisiológico e histopatológico

Os autores referem-se a caso de um jovem que, trabalhando em fábrica de esterilização de artigos médicos e em contato diário com o óxido de etileno, desenvolveu leve polineuropatia sensitivo-motora. Os estudos eletrofisiológicos evidenciaram neuropatia por degeneração axonal. A biópsia do nervo sural mostrou discreta perda de fibras mielínicas e sinais de degeneração e regeneração axonal. Este é o primeiro caso desta afecção descrita em nosso meio
