The effects of rapid intracarotid injection of 20 to 100 mg of sodium amobarbital were studied in three patients with bilateral myoclonic status epilepticus due to Jakob-Creutzfeldt disease, sequelae to anoxic encephalopathy, and hepatic coma, respectively. In each instance, the drug produced prompt abatement of clonic jerks contralaterally and attenuation of electroencephalographic epileptiform discharges ipsilaterally. These results suggest that the cerebral cortex actively participates in the elaboration of certain types of bilateral myoclonus in human beings.

A 12-year-old Bedouin boy presented with sudden asymmetrical status epilepticus. The presence of a scalp wound, rubbery cervical lymphadenopathy and a history of contact with cats suggested the diagnosis of cat-scratch disease complicated by encephalopathy. The diagnosis was supported by histological examination of a cervical lymph node and a positive skin test with cat-scratch antigen. The rapid establishment of the diagnosis avoided the necessity of elaborate and complicated neuroradiological investigations.

The record of 67 cases under 15 years of age who were hospitalized during status convulsivus from 1975 to 1978, the 348 cases who visited the hospital for the first time with epilepsy (Oct. 1977 to Sept. 1978) and the 32 cases who were hospitalized during status epilepticus from 1969 to 1974 and who are being followed up as outpatients were studied. The frequency of status epilepticus was 8% among epileptic children. There was no difference in the frequency of incidence between male and female. Patients with mental retardation, however, were revealed to have status epilepticus twice to three times more frequently as compared to cases without mental retardation. The major seizure types of status epilepticus in childhood were generalized tonic clonic convulsion and unilateral clonic convulsion. In 25% of the cases, status epilepticus was the first ictal manifestation. The major cause of status convulsivus was epilepsy, followed by encephalitis and encephalopathy, but cases due to brain tumor were rare. The drug of first choice for status convulsivus is diazepam. If there is any difficulty in controlling status convulsivus with diazepam, it may be worthwhile to consider what the problem is, causes of status convulsivus, seizure type, or basic disease of the patient. The effective dose of diazepam was within the range of 0.3--0.5 mg/kg. When the effect is not sufficient, the dose of diazepam should be increased to 1 mg/kg while watching the general condition of the patient. Factors affecting the prognosis of status convulsivus were its cause, duration, onset age and effectiveness of therapy during the acute stage. The frequency of cases who suffered disability after status epilepticus was 56%. (transient disability 43%, permanent disability 13%) The most frequent type of transient disability was hemiplegia. Most epileptic children who had repetitive status convulsivus revealed psychomotor retardation before first status. Factors which cause repetitive status seem to be hemispheric brain damage or diffuse corticocentrencephalic damage.

Large doses of phenytoin were administered on 159 occasions to 139 adult patients. Most patients had had more than three seizures or were in status epilepticus. Based on response to treatment, patients could be divided into two groups. Those with excellent response (recurrent seizures, 10%; mortality, 1%) included known epileptics with exacerbation of seizures (n = 75), atypical alcohol withdrawal (6), or miscellaneous conditions (17). Those with poor results (recurrent seizures, 57% mortality, 38%) included patients with anoxic or metabolic encephalopathy (14), stroke or other vascular disease (14), brain tumor (5), or trauma (5).

A 52 year old woman developed a severe encephalopathy with status epilepticus of six days duration in the terminal course of an acute hepatitis associated with hyperammonaemia and hyperventilation. Acute haemorrhagic lesions were observed in the brain, involving symmetrically both amygdala and cornu Ammonis. The sequential occurrence of these lesions with status epilepticus are discussed in the light of data from the literature.

Neuropathological considerations were performed on a case, who went into Lennox syndrome after an acute encephalopathy at the infantile period, and moreover who fell into an akinetic-mute state derived from brain damage by herniation caused by a head injury and subsequent status epilepticus. Neuropahtological background in the present case of Lennox syndrome is thought to be based on the widespread unilateral cerebral lesions and the basal ganglional, especially thalamic, degenerations derived secondarily from the diffuse cerebral damage. The patient revealed akinetic mutism with the disappearance of the epileptic seizures and the desynchronization of the EEG's, when the brain lesions formed at the adult period spread over the opposite hemispheric limbic system and the brain stem tectum.

Among 60 cases of status epilepticus, there were 45 cases of convulsive status and 15 cases of nonconvulsive or confusional status. In 37 cases, status was due to an identifiable cause. The most frequent etiologic factors were vascular (nine cases), traumatic (seven cases), and metabolic (five cases). Four patients with metabolic encephalopathy had focal status. While the possibility of expanding lesions should be investigated in every case of convulsive status, a complete metabolic screening is also necessary. Non-convulsive status was represented by two cases of psychomotor status and 13 cases of absence status. Clinically, these cases were characterized by various impairments of intellectual functioning and confusion. Diagnosis was determined by characteristic changes in the electroencephalogram. Aggressive treatment is indicated by one or more of the major anticonvulsants, supplemented by adequate oxygenation and maintenance of biochemical homeostasis.

Cat-scratch disease occasionally can be associated with encephalopathy and present as status epilepticus. However, the majority of these patients recover without sequelae, as shown by our patient and previous reports. Cat-scratch disease with encephalopathy should be considered in the differential diagnosis of status epilepticus in children.

Each EEG performed over a 3 year period at the University of Michigan with a diagnosis of generalized burst-suppression (BS) was reviewed. Ten EEGs from 10 patients with hypoxic-ischemic encephalopathy (HIE-BS) and 21 records from 8 patients with pentobarbital induced burst-suppression for treatment of status epilepticus (SE-BS) were reviewed. For each EEG, the mean duration of 40 interburst intervals (IBIs) as well as their coefficient of variability were calculated. We found that in the SE-BS group the coefficient of variability of IBI duration was highly correlated with the logarithm of mean IBI duration while in the HIE-BS group, there was no significant correlation between these 2 variables. This suggests that the underlying mechanism causing BS is different in the 2 groups and might be related to a uniform and progressive affection of similar brain structures in the SE-BS group and a more patchy and variable pathology in the HIE-BS group.

The correlations between sleep and prolonged epileptic activity are discussed on the basis of the status classification of Gastaut (1983). Little information is available on the interrelation of sleep and the status of tonic-clonic seizures (grand mal status). Most important is the therapeutical management of these cases. Tonic seizures have been reported to occur in large numbers during NREM sleep in patients with Lennox-Gastaut syndrome. A status-like increase is possible. Tonic seizures occur almost exclusively during sleep. Myoclonic status epilepticus arising (a) in the course of primary generalized epilepsy and (b) in the course of encephalopathies, are usually markedly attenuated during sleep. In absence status (petit mal status) synchronized sleep generally fragments the continuous discharge which is replaced by isolated bursts of polyspikes, or polyspike and wave complexes. The absence status can recur upon awaking during the night or in the morning. The abnormal EEG activity of a petit mal status can, however, occasionally persist during the whole night. Improvement as well as activation during sleep have been observed in elementary (= simple) partial status epilepticus; improvement seems to be more frequent. Epilepsia partialis continua may persist or decrease during sleep. An increase as well as decrease of motor phenomena has been observed during the REM stages. 'Epileptic aphasia' of childhood is associated with subclinical bioelectric status epilepticus during sleep. The electrical status epilepticus must be delineated as a separate group. The term encephalopathy related to electrical status epilepticus during slow sleep (ESES) has been proposed on the basis of associated psychic syndromes. This form of status epilepticus disappears during the waking state and during REM sleep. Cases with hypsarrhythmia without clinical signs may also be classified under the group of electrical or bioelectrical status. In some cases, a continuous hypsarrhythmia is observed only during sleep. In this context, one must also mention those patients who demonstrate continuous activation of spikes, or spike and wave potentials (without clinical seizures) during eye closure.
