Predictors of Mechanical Ventilation in Guillain-Barré Syndrome with Axonal Subtypes.

Background: The early clinical predictors of respiratory failure in Latin Americans with Guillain-Barré syndrome (GBS) have scarcely been studied. This is of particular importance since Latin America has a high frequency of axonal GBS variants that may imply a worse prognosis.

Methods: We studied 86 Mexican patients with GBS admitted to the , a referral center of Mexico City, to describe predictors of invasive mechanical ventilation (IMV).

Clinical and neurophysiological description of patients with POEMS syndrome.

Introduction: POEMS syndrome (polyneuropathy, organomegaly, endocrinopathy, monoclonal protein, skin changes) is a monoclonal gammopathy with polyneuropathy as a mandatory criterion.

Objective: To describe potential associations between clinical expression and electrodiagnostic patterns in POEMS syndrome.

Method: Observational, retrospective, cross-sectional study of cases cared for in a referral center, diagnosed with POEMS syndrome from 2009 to 2019.

Levosulpiride Relieved Persistent Hiccups in a Patient With COVID-19 and Vascular Cognitive Impairment.

Background: The coronavirus disease 2019 (COVID-19) is a systemic illness that implies neurological features and complications. Persistent (>48 hours) hiccups (ie, singultus or hiccoughs) have been recently described as a rare presentation of COVID-19. Even when considered benign, the frequency and duration of hiccup spells can be burdensome and sometimes difficult to treat.

Prediction of acute neurovascular syndromes with prehospital clinical features witnessed by bystanders.

Background: The prompt recognition of an acute neurovascular syndrome by the patient or a bystander witnessing the event can directly influence outcome. We aimed to study the predictive value of the medical history and clinical features recognized by the patients' bystanders to preclassify acute stroke syndromes in prehospital settings.

Methods: We analyzed 369 patients: 209 (56.
