As the anticonvulsant plasma level of diazepam (DZP) after intravenous injection is maintained only for a short period, it is profitable to administer DZP as an intravenous infusion. It has, however, been claimed that DZP cannot be mixed with dextrose injection as DZP would precipitate. As this is in contrast to our clinical experience we added DZP of various brands to dextrose injections. A precipitate was in fact found in dextrose injections containing Valium and Stesolid whereas Diazepam A.L. was not only slightly cloudy. The concentration of DZP was, however, the same in all the samples and corresponded to the calculated concentration. The precipitate in the solutions with Valium and Stesolid which did not pass the filter must therefore be due to additives, most probably benzoates. On the basis of these findings and our clinical experience of this mode of administration we recommend the infusion method as one of the most effective in the acute treatment of status epilepticus.

Alumina cream epileptic focus was established in the right sensorimotor cortex in 20 split-brain cats (partial or complete). EEG and behavioral observations were made in a period ranging from 24 to 836 days. Four types of EEG changes after alumina cream injection were differentiated. These types could be related to the direct effects of brain damage and to development of epilepsy. Spikes and sharp waves and paroxysmal discharges (focal and multifocal) were observed in about 60% of the cats. Clinical seizures developed in about the same percentage of the animals. These values are below those reported for cats with intact interhemispheric commissures. Diphenylhydantoin (DPH) was given orally in a daily dose of up to 15 mg/kg body weight in 9 animals with developed epileptic EEG activity. Five of them had epileptic seizures. DPH was introduced not earlier than 1.5 months after intracortical alumina cream injection. The plasma level of DPH varied between 7-20 mug/ml. This dose produced chronic symptoms of intoxication. Neither EEG changes nor clinical seizures were entirely controlled by this drug. Additional doses of Relanium (diazepam), and phenobarbital were necessary to stop generalized seizures or status epilepticus.

Serum anticonvulsant determinations made possible the identification of an unusual cause of status epilepticus and assisted with appropriate therapy in an epileptic patient with second-degree burns. The seizures were associated with a serum phenytoin concentration of 3.5 mug per milliliter. This suboptimal concentration of drug developed despite continuation of the patient's customary oral dose of phenytoin led to the conclusion that the unexpected decrement in serum anticonvulsant concentration was related to an experiment in absorption of that drug, possibly caused by the concurrent administration of oral oxacillin.

We report the case of a young female patient with photosensitive primary epilepsy who presented partial motor status epilepticus provoked by the act of shutting the eyes. Clinical, EEG and neuroimage data are presented and discussed.

Several experiments were designed to evaluate a secondary humoral response following limbic seizures. After baseline antigen binding capacity (ABC) had been determined for the primary response, a second subcutaneous injection of the antigen (human serum albumin) was accompanied by an injection of either lithium (3 mEq/kg)-pilocarpine (30 mg/kg) or one of two comparator treatments: metrazol (30 mg/kg) or cyclophosphamide (50 mg/kg); other rats served as drug controls. Only the groups that received the lithium-pilocarpine (status epilepticus) or cyclophosphamide (no seizure) displayed significant immunosuppression after 5 but not 10 days. The results support the hypothesis that seizure activity within the amygdaloid-hippocampal complex modulates immunocompetence through corticotropin mechanisms.

Nineteen patients with severely handicapped children were divided into 3 groups; tube-fed patients (group 1, n = 8), oral-fed patients with dysphagia (group 2, n = 3) and oral-fed patients (group 3, n = 8). Clinical symptoms, past history, cranial CT, EEG, blink reflex and auditory brainstem response were evaluated in these patients. All patients of group 1 and 2 could not control head or sit by themselves. They needed naso-oral suction. However, nasal airway, intubation and tracheostomy were necessary only in group 1 patients. Five out of 8 patients of group 3 could control head and sit by themselves. No one needed naso-oral suction. CT revealed ventricular dilatation or prominent destructive lesions in group 1. However, patients of group 2 and 3 showed the lesions of mild to moderate degree. EEGs showed poorly developed background activities or electrical status epilepticus in group 1, while they showed relatively well-developed background activities with less prominent paroxysmal discharges in group 2 and 3. R2 component of blink reflex was absent bilaterally in 90% patients of group 1 and 2, while unilateral R2 at least was present in group 3. Feeding problems in severely handicapped children were affected by combination of cerebrum and brainstem involvements. Examination of cranial CT, EEG and blink reflex was useful to determine the method of feeding.

The efficacy of valproic acid (VPA) in control of generalized convulsive status epilepticus was tested in a rat model. Rats with cortical cobalt lesions were injected with homocysteine thiolactone to induce secondarily generalized tonic-clonic seizures (GTCS). The median effective dose (ED50) for control of GTCS was 211.9 mg/kg (270 micrograms/ml in serum 30 min post dose) when treatment was given intraperitoneally after the second GTCS. VPA entered both serum and brain very rapidly after injection, with little change in concentration from 5 to 30 min post dose. In earlier experiments with phenytoin, phenobarbital, diazepam and lorazepam in this model, we found that the serum concentrations produced by the ED50s versus GTCS were very similar to those which have been reported to be effective in treating human status epilepticus. If this same relationship holds true for VPA, we would predict that a serum concentration of around 270 micrograms/ml VPA would be required for control of generalized convulsive status epilepticus in human patients. The safety of this high a concentration of VPA has not been tested.

In 51 children with different types of epilepsy, blood flow velocities in the middle cerebral artery were recorded continuously by transcranial Doppler sonography during a standard electroencephalogram of 30 min duration. In 16 children 33 epileptic seizures were recorded. During tonic seizures, the mean flow velocity increased to a maximum of 133%-191% (median 160%) of the baseline values. Tonic-clonic seizures were also accompanied by a velocity increase. During absence seizures the mean flow velocity decreased to a minimum of 46%-82% (median 71%) of the baseline values. Changes in cerebral metabolism and arterial blood pressure in the presence of disturbed autoregulation are thought to be factors causing these alterations. No alteration of the flow velocities occurred in cases of petit-mal status, electrical status epilepticus and in 35 children with generalized epileptic discharges of up to 5 s duration without clinical manifestations.

The authors present the clinical case of a boy manifesting eyelid myoclonias on eye closure. The corresponding electroencephalographic recording was characterized by unceasing spike activity, constituting a sort of electrical status epilepticus. There was no loss of consciousness or differences between results of neuropsychological tests with eyes open and closed.

Three cases of status epilepticus not responsive to an aggressive treatment are described. The seizures and EEG activity were rapidly brought under control with a continuous infusion of propofol (3-6 mg/kg/hour), maintained between 21 hours and 7 days. Patient awakening at the end of the infusion period was rapid and without sequelae.
