Microcephaly and arthrogryposis multiplex congenita: The full-blown CNS spectrum in newborns with ZIKV infection.

The recent alarming statements concerning the newborn ZIKV-induced microcephaly epidemics in the Northeast of Brazil, released by the Brazilian Ministry of Health, as well as important international health agencies, such as the World Health Organization and the Pan American Health Organization, raised many "why and how" questions so far, that will hopefully be scientifically answered, as more researches in that regard come up in the long term. In this paper, we describe another potentially ZIKV-induced central nervous system and musculoskeletal disorder that has accompanied microcephaly in these children: atrhogryposis multiplex congenita. The goal is to bring up some hypotheses for possible underlying molecular mechanisms based on published data taken from animal models, such as ovine and cattle, which once infected by other types of arboviroses and viruses that also belong to the Flaviviridae family, presented, too, with the full-blown CNS spectrum of malformations at birth.

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

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.

Scrutinizing brain magnetic resonance imaging patterns in Angelman syndrome.

Background: Global developmental delay, lack of speech, and severe epilepsy are the characteristic hallmarks of Angelman syndrome (AS). The purpose of this study was to explore the utility of brain magnetic resonance imaging (MRI) as an ancillary tool for the diagnosis of AS.

Material And Methods: Brain MRI images of nine laboratory-confirmed patients with AS from a neurorehabilitation center in Rio de Janeiro were reviewed.

Guidelines for the diagnosis, treatment and clinical monitoring of patients with juvenile and adult Pompe disease.

Pompe disease (PD) is a potentially lethal illness involving irreversible muscle damage resulting from glycogen storage in muscle fiber and activation of autophagic pathways. A promising therapeutic perspective for PD is enzyme replacement therapy (ERT) with the human recombinant enzyme acid alpha-glucosidase (Myozyme®). The need to organize a diagnostic flowchart, systematize clinical follow-up, and establish new therapeutic recommendations has become vital, as ERT ensures greater patient longevity.
