Comparative Study
Fasciculations and their F-response revisited: high-density surface EMG in ALS and benign fasciculations.
To compare the prevalence of fasciculation potentials (FPs) with F-responses between patients with amyotrophic lateral sclerosis (ALS) and patients with benign fasciculations. ⋯ F-waves confirm the distal origin of FPs for an individual axon. The occurrence of these FPs in a benign condition suggests that the generation of ectopic discharges in the distal axons is not specific to progressive neurodegeneration.

Comparative Study
Nonconvulsive status epilepticus in adults: electroclinical differences between proper and comatose forms.
Nonconvulsive status epilepticus (NCSE) represents an important percentage of status epilepticus in adults, but detailed studies of both NCSE proper and comatose NCSE are lacking. We retrospectively analyzed a prospectively collected series of 50 adult patients with a diagnosis of NCSE whose electroencephalograms (EEGs) have been interpreted for a period of 10 years by the same investigator. ⋯ A distinction between NCSE proper (ambulatory forms of NCSE) and comatose NCSE is useful in the clinical practice and, therefore, it should taken in account in the design of future investigations on this heterogeneous epileptic condition.

Comparative Study
Quantitative electroencephalography in a swine model of cerebral arterial gas embolism.
Cerebral arterial gas embolism (CAGE) is a serious hazard in cardiovascular surgery and other invasive procedures. We used a swine model of CAGE to determine if quantitative electroencephalography (qEEG) is a useful tool in diagnosis and prognostication of CAGE. ⋯ This study provides evidence for the utility of qEEG for diagnosis and prognosis in CAGE. Further studies are necessary to investigate the use of this method in patients.
