Encefalitis de Bickerstaff / Bickerstaff encephalitis

La encefalitis de tallo cerebral es un síndrome que se presenta con alteración del estado de conciencia, oftalmoplejia, ataxia y signos piramidales. Esta condición neurológica rara que fue descrita en 1950 por primera vez, presenta similares características clínicas a Síndrome de Guillain-Barré, por lo que representa un reto diagnóstico para el clínico. En este artículo se presenta el caso clínico de una paciente de 51 años de edad que se presenta con alteración del estado de conciencia, es llevada a unidad de cuidado intensivo de adulto donde se considera el diagnóstico de encefalitis de Bickerstaff, tras un exhaustivo abordaje diagnostico; el cual se describe, al igual que sumanejo y evolución...(AU)

Brain stem encephalitis is a syndrome that presents with altered state of consciousness, ophthalmoplegia, ataxia and pyramidal signs. This rare neurological condition that was described in1950 by The first time, it presents similar clinical characteristics to Guillain-Barré syndrome, which represents a diagnostic challenge for the clinician. This article presents the clinical case of a 51-year-old patient who presents with altered state of consciousness, is taken to the adult intensive care unit where the diagnosis of Bickerstaff encephalitis is considered, after an exhaustive diagnostic approach ; which is described, as well as its management and evolution ...

Clinical and cerebrospinal fluid findings contribute to the early differentiation between infectious and noninfectious encephalitis.

Early recognition and prompt specific treatment are crucial factors influencing the outcome of patients with acute encephalitis. The aim of this study was to determine the main causes of acute encephalitis in our population and to find predictors that may lead to specific diagnosis. Adult patients admitted to our hospital with suspected diagnosis of encephalitis in the period 2006-2013 were included. One hundred and five medical records were analyzed. Eighty-two patients with infectious encephalitis were identified (78% of total cases), 53 (65%) men and 29 (35%) women, mean age 47.8 years. The most common microorganisms identified were: HSV-1 (11%), VZV (10%), HSV-2 (5%) and EBV (5%). Twenty-three patients (22% of the series) had non-infectious encephalitis. Headache (p < 0.0001) and fever (p = 0.008) were more frequent in encephalitis of infectious origin. Protein levels and white blood cell counts in the cerebrospinal fluid were significantly higher in patients affected by infectious encephalitis than in those affected by noninfectious encephalitis (OR 95% CI 12.3 [2.9-51.7] and OR 95% CI 7.4 [2-27], respectively). Identifying specific causal agents of acute encephalitis remains a major challenge. Cerebrospinal fluid markers, as well as specific clinical findings, may however contribute to initial differentiation between infectious and noninfectious causes.
