barre syndrome

Carey L Medin, Alan L Rothman
Once obscure, Zika virus (ZIKV) has attracted significant medical and scientific attention in the past year because of large outbreaks associated with the recent introduction of this virus into the Western hemisphere. In particular, the occurrence of severe congenital infections and cases of Guillain-Barré syndrome has placed this virus squarely in the eyes of clinical and anatomic pathologists. This review article provides a basic introduction to ZIKV, its genetics, its structural characteristics, and its biology...

Guillain-Barré syndrome (GBS) is mainly classified into acute inflammatory demyelinating polyneuropathy (AIDP) and acute motor axonal neuropathy (AMAN). Although diagnosis of GBS requires progressive weakness and universal areflexia or hyporeflexia, cases of GBS with preserved or increased deep tendon reflexes (DTRs) have been increasingly recognized. We report three cases of GBS, presenting at a single unit in six months. Our first case presented with pure sensory symptoms. The second case had nonspecific generalized weakness, while the third presented with typical ascending weakness...

The World Health Organization (WHO) has coined the term expanded dengue to describe cases which do not fall into either dengue shock syndrome or dengue hemorrhagic fever. This has incorporated several atypical findings of dengue. Dengue virus has not been enlisted as a common etiological agent in several conditions like encephalitis, Guillain Barre syndrome. Moreover it is a great mimic of co-existing epidemics like Malaria, Chikungunya and Zika virus disease, which are also mosquito-borne diseases. The atypical manifestations noted in dengue can be mutisystemic and multifacetal...

Zika virus (ZIKV) is a deadly flavivirus that has spread from Africa to Asia and European countries. The virus is associated with other viruses in the same genus or family, transmitted by the same mosquito species with known history of fatality. A sudden increase in the rate of infection from ZIKV has made it a global health concern, which necessitates close symptom monitoring, enhancing treatment options, and vaccine production. This paper reviewed current reports on birth defects associated with ZIKV, mode of transmission, body fluids containing the virus, diagnosis , possible preventive measures or treatments, and vaccine development...

INTRODUCTION: Hodgkin lymphoma (HL) is a common lymphoid malignancy rarely associated with Guillain-Barré Syndrome (GBS). In most cases, GBS does not precede HL. METHODS: We describe a patient with acute inflammatory demyelinating polyneuropathy (AIDP) who fulfilled criteria for GBS that heralded undiagnosed HL. RESULTS: Cerebrospinal fluid (CSF) studies revealed albuminocytologic dissociation with significant protein elevation (250 mg/dL)...

INTRODUCTION: The most efficient method of performing electrophysiology for Guillain-Barré syndrome (GBS) is unknown. METHODS: We retrospectively analyzed electrophysiological data of 97 consecutive GBS patients from Birmingham, U.K. (2001-12) studied ≤3 weeks post-onset. RESULTS: The sensitivity of electrophysiology for each GBS subtype was dependent on the tested upper and lower limb nerves. In acute inflammatory demyelinating polyneuropathy (AIDP), abnormalities were predominant in the arms, whereas leg abnormalities predominated in axonal GBS...

Zika virus (ZIKV) infection and its associated complications have become a significant public health concern. Zika virus is a Flavivirus, and is transmitted to humans by Aedes species mosquitoes. In May 2015, the World Health Organization reported the first locally acquired transmission of ZIKV in Brazil, the first case in the Western Hemisphere. There have also been reports of increased incidence of microcephaly and other neurologic complications associated with ZIKV infection, as well as a 20-fold increase in the incidence of Guillain-Barre Syndrome during ZIKV outbreaks...

Epstein-Barr virus (EBV) infection is ubiquitous in humans, but the majority of infections have an asymptomatic or self-limiting clinical course. Rarely, individuals may develop a pathological EBV infection with a variety of life threatening complications (including haemophagocytosis and malignancy) and others develop asymptomatic chronic EBV viraemia. Although an impaired ability to control EBV infection has long been recognised as a hallmark of severe T-cell immunodeficiency, the advent of next generation sequencing has identified a series of Primary Immunodeficiencies in which EBV-related pathology is the dominant feature...

The epidemics of Ebola virus in West Africa and Zika virus in America highlight how viruses can explosively emerge into new territories. These epidemics also exposed how unprepared we are to handle infectious disease emergencies. This is also true when we consider hypothesized new clinical features of infection, such as the associations between Zika virus infection and severe neurological disease, including microcephaly and Guillain-Barré syndrome. On the surface, these pathologies appear to be new features of Zika virus infection, however, causal relationships have not yet been established...

The Zika virus (ZIKV) is a flavivirus of the family Flaviviridae, which is similar to dengue virus, yellow fever and West Nile virus. Recent outbreaks in South America, Latin America, the Caribbean and in particular Brazil have led to concern for the spread of the disease and potential to cause Guillain-Barré syndrome and microcephaly. Although ZIKV has been known of for over 60 years there is very little in the way of knowledge of the virus with few publications and no crystal structures. No antivirals have been tested against it either in vitro or in vivo...

Worldwide concern over Zika virus causing Guillain-Barre syndrome (GBS) soared after recent reports that Zika-related weakness was due to GBS. A global strategic response plan was initiated with recommendations for at-risk countries to prepare for GBS. This plan has major economic implications, as nations with limited resources struggle to implement costly immunotherapy. Since confirmation of causality is prerequisite to providing specific management recommendations, it is prudent to review data endorsing a GBS diagnosis...

Recent views on Guillain-Barré syndrome (GBS) question the accuracy of classification into axonal and demyelinating subtypes that represent convergent neurophysiological phenotypes rather than immunological targets. Instead it has been proposed to clarify the primarily affected fibre subunit in nerve biopsies. As nerve biopsies rarely are part of routine work-up in human patients we evaluated tissues taken from companion animals affected by GBS-like polyradiculoneuropathy to screen for distribution of immune cells, targeted fibre components and segregating non-inflammatory lesions...

Guillain-Barré syndrome has been reported in pregnancy and is a potentially lethal condition. It affects the nervous system with acute onset of symmetric ascending weakness and may result in frank respiratory failure and autonomic dysfunction. Most patients recall symptoms of a respiratory or gastrointestinal illness in the weeks preceding the onset of weakness. Recent evidence suggests a potential role of the Zika virus as a trigger for the syndrome. The diagnosis of Guillain-Barré is clinical. Supportive measures include venous thromboembolism prophylaxis, aggressive physical therapy, pressure ulcer prevention, enteral nutrition, and respiratory support...

The unexpected emergence of Zika virus (ZIKV) in the Pacific Islands and Latin America and its association with congenital Zika virus syndrome (CZVS) (which includes microcephaly) and Guillain-Barré syndrome (GBS) have stimulated wide-ranging research. High densities of susceptible Aedes spp., immunologically naive human populations, global population growth with increased urbanization, and escalation of global transportation of humans and commercial goods carrying vectors and ZIKV undoubtedly enhanced the emergence of ZIKV...

The current outbreak of Zika virus (ZIKV) in South America is one of the most serious public health emergencies since the Ebola outbreak of West Africa [2014]. ZIKV belongs to the flaviviridae family and has two lineages (Asian and African). The virus was first discovered in Uganda [1947] and the first human infection was identified in Nigeria [1952]. The current epidemic is the third of its type after that of Yap Island, Micronesia [2007] and French Polynesia [2013]. Phylogenetic studies revealed that the current strain shares about 99...

Zika virus is an arbovirus belonging to the Flaviviridae family known to cause mild clinical symptoms similar to those of dengue and chikungunya. Zika is transmitted by different species of Aedes mosquitoes. Nonhuman primates and possibly rodents play a role as reservoirs. Direct interhuman transmission has also been reported. Human cases have been reported in Africa and Asia, Easter Island, the insular Pacific region, and Brazil. Its clinical profile is that of a dengue-like febrile illness, but recently associated Guillain-Barre syndrome and microcephaly have appeared...
