To characterize a cohort of patients with the signs and symptoms of posterior reversible encephalopathy syndrome (PRES), but with clinical and radiologic involvement of the spinal cord. ⋯ In light of the already wide definition of PRES, we propose a new syndrome named PRES with spinal cord involvement (PRES-SCI). Clinicians should suspect PRES-SCI when patients with PRES have neurologic signs referable to the spinal cord, extreme elevation in blood pressure, MRI lesions that extend to the cervicomedullary junction, or grade IV hypertensive retinopathy. These clinical scenarios should prompt a cervical spine MRI to help guide patient management decisions and prognostication. When clinicians evaluate longitudinally extensive spinal T2 hyperintensities, they should consider PRES-SCI, which, if diagnosed, would spare patients the morbidity of a standard myelitis workup and empiric treatment.

To objectively measure daytime sleepiness and to assess for clinical and polysomnographic determinants of mean sleep latency in adult patients with somnambulism (sleepwalking [SW]) or sleep terrors (ST) compared with controls. ⋯ Excessive daytime sleepiness is a common complaint in subjects with SW or ST and shorter sleep latencies in the early morning hours. Despite an increased slow-wave sleep fragmentation found in these patients, we did not identify any association with the level of daytime sleepiness.

To assess the occurrence of narcolepsy after influenza vaccines used in the United States that contained the influenza A(H1N1)pdm09 virus strain. ⋯ Influenza vaccines containing the A(H1N1)pdm09 virus strain used in the United States were not associated with an increased risk of narcolepsy. Vaccination with the influenza A(H1N1)pdm09 vaccine viral antigens does not appear to be sufficient by itself to increase the incidence of narcolepsy in a population.

To pool data from completed amyotrophic lateral sclerosis (ALS) clinical trials and create an open-access resource that enables greater understanding of the phenotype and biology of ALS. ⋯ The PRO-ACT database is the largest publicly available repository of merged ALS clinical trials data. We report that baseline levels of creatinine and uric acid, as well as baseline BMI, are strong predictors of disease progression and survival.
