We report the fourth case of partial status epilepticus (SE) in benign epilepsy of childhood with rolandic spikes (BECRS). The child suffered long-lasting attacks involving the mouth and pharynx, clinically manifest as speech arrest, sialorrhea, and drooling. Both clinical and electroencephalogram (EEG) data were compatible with the diagnosis of BECRS. Only during SE was the clinical picture similar to that observed in the operculum or Foix-Chavany-Marie syndrome. SE remission was obtained with the usual antiepileptic drug therapy (diazepam, clobazam, valproate). EEG records showed additional patterns of continuous spike-waves during slow sleep and specific inhibition and blocking of interictal centrotemporal spikes by mouth and/or tongue voluntary movements.

Prolonged isolated sialorrhea of epileptic origin was described by Penfield and Jasper (1954) in a patient with a lesional epilepsy. A child with prolonged but intermittent drooling, lingual dyspraxia, and other clinical and electroencephalographic (EEG) features compatible with benign childhood epilepsy with centrotemporal spikes (BCECS) is described. The fluctuant course of the symptomatology and correlation with the intensity of the paroxysmal discharges on EEG are consistent with an epileptic dysfunction located in the lower rolandic fissure. No lesion was demonstrated by magnetic resonance imaging (MRI). Our case bears analogies with the recently reported status epilepticus of BCECS and the "acquired aphasia-epilepsy syndrome."

A 5-year-old girl developed recurrent prolonged episodes of severe oral apraxia, dysarthria, and drooling, similar to the opercular syndrome in children. Each episode lasted several weeks to > 6 months and was associated with exacerbation of epileptiform activity in her EEG. Electrographic status epilepticus during slow wave sleep (ESES) was recorded during three of the exacerbations. The EEG improved markedly when clinical symptoms subsided. Antiepileptic drugs (AEDs) were not effective, although there was some improvement when they were combined with a ketogenic diet. A similar case was described by Roulet et al. We believe that this is a distinct epileptic syndrome, equivalent to the Landau-Kleffner syndrome (LKS).

This study reports on a girl with a permanent cerebral lesion and opercular syndrome after status epilepticus (SE). She had previously been healthy and had her first focal motor seizure at 5 years of age, which was controlled with intravenous phenytoin and rectal diazepam. Twenty-four hours later, she developed partial SE consisting of right facial twitching and right-hand clonic movements. These uncontrollable seizures lasted for 5 days, after which the partial SE changed to generalized SE, and the seizures continued for another 5 days. CT performed the day before onset of SE revealed no brain abnormality. Another CT performed a year later disclosed bilateral brain lesions, more severe in the left hemisphere. Follow up at 16 years of age revealed moderate motor sequelae of the right-hand side of the body, anarthria, difficulty chewing, dysphagia, bilateral facial weakness, and drooling, all of which clinically characterize opercular syndrome. An MRI study performed at 14 years of age showed a cerebral parenchymatous lesion which extended between the parietal cortices of both hemispheres, more severe on the left side, and which crossed the corpus callosum, destroying the posterior-middle zone. Evidence from the CT indicates that the lesion was not present before onset of SE. It seems likely that the focal SE caused the focal brain damage, but the possibility that the subsequent generalized SE played a role cannot be excluded.

A 9-year-old male with congenital bilateral perisylvian syndrome is described. He had pseudobulbar palsy, mental retardation, and intractable epilepsy. Computed tomography and magnetic resonance images of the brain demonstrated bilateral perisylvian malformations and a diffuse pachygyric appearance. At 8 years of age, he had episodes of excessive drooling, fluctuating impairment of consciousness, unsteady sitting, and frequent head drop that lasted several days. The electroencephalogram demonstrated continuous diffuse slow spike and waves. These findings suggested atypical absence status epilepticus. Intravenous administration of diazepam resulted in transient improvement of clinical and electroencephalographic findings. Status epilepticus recurred within several minutes after diazepam administration. Although no patient has been reported to have a history of status epilepticus among those affected by this syndrome, it seems that atypical absence status can occur more frequently than expected, as seen in Lennox-Gastaut syndrome. After recognition and confirmation of nonconvulsive status epilepticus, immediate treatment must be attempted.

In patients with focal epilepsy, focal neurological dysfunction can occur due to status epilepticus and also as a post-ictal phenomenon. Bulbar dysfunction as evident by drooling, dysarthria, swallowing difficulties, and palatal-glossalpharyngeal weakness has been reported in conjunction with epilepsy. This is non-progressive and is correlated in its severity with the frequency of seizures. Accompanying EEG discharges are often localized to rolandic areas that cortically represent oral movements and salivation. We report a 6-year-old male and a 6 1/2-year-old female with progressive bulbar dysfunction resulting from epilepsy. Ictal EEGs in patient 1 did not confirm a diagnosis of epilepsy. With no evidence of a cortical or brainstem focus from EEG or MRI, it is very difficult to explain the mechanism of bulbar dysfunction. The complete restoration of bulbar function after treatment with antiepileptic drugs demonstrates the need to consider epilepsy in similar clinical situations.

The vagus nerve stimulator has become a standard modality for intractable pediatric epilepsy. We reviewed our experience with major adverse events, after accidental puncture of a stimulator wire by an emergency room physician seeking intravenous access to treat status epilepticus. The Children's National Medical Center database was reviewed for patients undergoing vagus nerve stimulator placement between January 1988 and June 2006. Patient characteristics, duration of therapy, and treatment-limiting adverse events were noted. Of 62 patients implanted over 8 years, 22 (35%) had adverse events which led to a change in therapy. Adverse events included prominent drooling, coughing, throat discomfort, dysphagia, wound infection, difficulty breathing, vomiting, vocal-cord weakness, lead failure, and iatrogenic (piercing of wire; surgical clipping of wire during revision). Eight patients required nonroutine surgical intervention (13%). There were two unusual case presentations. In a 13-year-old boy with status epilepticus at an outlying emergency department, the stimulator line was pierced in search of intravenous access. In a 25-year-old housepainter, neck paresthesias upon right lateral neck turning were attributed to insufficient strain relief. Treatment-limiting adverse events occurred in approximately one-third of patients. Unanticipated adverse events included misidentification of the wire for intravenous access, clipping of the wire during surgical dissection, and cervical dysesthesias associated with head-turning.
