Does the presence of short and sharp MEG spikes imply focal cortical dysplasia?
MEG epileptiform discharges of short duration and steep tilt characterize FCD, especially when located at the superficial neocortical gyrus. We speculate that this particular spike morphology results from the intrinsic epileptogenicity of FCD. Morphological analysis of MEG spikes can evaluate the etiology of epileptogenic lesions and detect a strong, localized epileptogenic focus such as that typically observed in FCD.
Markers of acute HEV infection were present in 6.5% of patients in our cohort of cirrhotics with histologically proven severe AH, without any impact on short-term or long-term outcome. Whether systematic screening of acute HEV infection in this population should be performed remains an unsolved question.
