We retrospectively reviewed the clinical features and results of investigation of 62 patients with acute encephalitis or encephalopathy in the acute phase to identify the prognostic factors in the development of postencephalitic epilepsy. Patients who later developed epilepsy showed more marked disturbance of consciousness, convulsions, and seizure activities on EEG during the acute phase than those who did not. There was no relation between CSF abnormalities and postencephalitic epilepsy. Control of convulsions during the acute phase, especially of status epilepticus, seems to be important to improve the prognosis.

202 cases of children with shunted hydrocephalus of congenital or acquired origin were studied and the incidence of seizure disorder was found to be 39%. However in only 17% of cases was the seizure disorder found to be persistent. Focal seizures were rarer than expected. If focal seizures were present they did not appear to be related to shunt site. 9.4% of children suffered an episode of status epilepticus. A large number of incidents of seizures could be shown to have a specific precipitant, usually CSF infection or shunt related problems. No aspect of birth history or development or treatment of the hydrocephalus was related to the occurrence or seizure disorder or type of fit experienced. Children with persistent seizure disorder were found to be more likely to be of low IQ, physically handicapped and at Special School.

Cerebrospinal fluid concentration of 5-hydroxyindolacetic acid (5-HIAA) was determined in 15 patients soon after recovery from status epilepticus. Similarly, patients with generalised epilepsy and persons without epilepsy, serving as controls, were also studied. The level of 5-HIAA was significantly reduced in all epileptic patients with or without status epilepticus, as compared with the nonepileptic control group. However, there was no statistical difference between patients with status epilepticus and those with generalised epilepsy. Among patients with epilepsy, low 5-HIAA levels in CSF could not be correlated with frequency or severity of seizures, or with antiepileptic drugs. A link between CSF 5-HIAA and susceptibility of humans to epilepsy may indicate a possible future therapeutic approach.

A 17 year old high school boy experienced fever and diarrhea, which subsided within 4 days by appropriate medications. Six days later, however, he developed unsteadiness and limb spasm. On the morning of admission, he was found to have drowsiness, dysarthria, gait disturbance and involuntary jerks. When he was brought to the hospital, he was lethargic but could follow simple verbal commands. Frequent involuntary movements manifested by facial grimacings, limb spasms and twitchings with dystonic features were seen. Decorticate posturing was readily elicited by painful stimuli. There was no meningeal irritation sign or gross sensory impairment. The deep tendon reflexes were symmetrically exaggerated with bilateral Babinski signs. Bilateral lateral rectus muscle weakness was found together with mild ptosis and upward gaze limitation. Nystagmus was not present and the funduscopic examination was normal. Immediately he was placed on anticonvulsants, steroid hormone, gamma-globulin and antibiotics as well. A brain CT scan and a CSF examination revealed no abnormality. Meanwhile he continued to show a progressive deterioration associated with fever and status epilepticus, and within 24 hours he lapsed into coma in decorticate posture. An EEG obtained at the 3rd hospital day was compatible with spindle coma. In spite of aggressive treatment he remained febrile and comatous. Therefore, vidarabine (adenine arabinoside) was initiated from the 3rd hospital day for 5 days. Then he began to groan and show frequent choreic movements. For the subsequent 2 weeks he made a slow recovery.(ABSTRACT TRUNCATED AT 250 WORDS)

The efficacy of intravenous phenytoin for the treatment of status epilepticus is related to the rapid entry of phenytoin into brain parenchyma. There is no information concerning the correlation between phenytoin serum and CSF concentrations in children, and the application of CSF data to clinical use. We report 7 children (2-11 yrs) who were treated or exposed to phenytoin in doses between 10.5-230 mg/kg. Lumbar puncture was performed 9 times in 6 of the patients. In one patient, an intraventricular catheter permitted successive assessment of CSF phenytoin concentrations. The ratio of CSF/serum phenytoin concentrations was 0.16 +/- 0.08, with gradual increase over the first 8 hours as the serum phenytoin concentration decreased. There was good correlation between therapeutic outcome and CSF phenytoin levels higher than 2 mcg/ml. In one patient the coma state secondary to phenytoin intoxication was associated with high CSF concentration (6 mcg/ml).

A 70 year-old-man with recurrent herpetic keratitis had a meningo-encephalitis with transient left hemiplegia and disorders of consciousness. EEG disclosed periodic slow waves on the right temporal region. Isotope and CT scans showed focal abnormalities in the same region. Antibodies to herpes simplex virus were demonstrated by complement fixation in serum and specific antiherpes IgG and IgM by immunofluorescence assay in serum and CSF. A year later the patient had a status epilepticus. CT scan showed a large right temporal hypodense area. CSF was abnormal with pleiocytosis, increased protein and IgG levels. High titers of antiherpes IgG persisted in serum and CSF. Neuropsychological tests did not demonstrate any memory impairment. The occurrence of persistent inflammation after herpes simplex encephalitis is discussed. The unusual benign course without antiviral therapy, may be related to the reactivation of a latent infection with an efficient immunological response. The unilateral temporal necrosis may explain the absence of amnestic sequelae.

Nonketotic hyperglycinemia was diagnosed in identical twins with lethargy and respiratory failure in the neonatal period. Therapy with strychnine (0.32 mg/kg/day) resulted in great reductions in CSF and plasma glycine levels and improvement in muscle tone, respiration, and ability to suck. Myoclonic seizures were partially controlled by therapy with clonazepam. Higher dosages of strychnine (up to 2.0 mg/kg/day) were needed to counteract the increased lethargy following administration of clonazepam. At 5 months of age, the twins' developmental performance remained below the 1-month level despite adequate somatic growth. The twins died suddenly of status epilepticus at 6 1/2 months of age.

Among the calls for information recently received by the French Poison Control Centers, 78 concerned a liver protecting agent, thiazolidine carboxylic acid. In almost every case, doses well above the therapeutic range have provided a status epilepticus. Thus confirming the neurotoxicity of the drug which had been known to the Poison control Centers for the past 10 years. Several patients had also metabolic acidosis, severe hypoglycaemia, or, more scarcely, hyperglycaemia. Seizures convulsions occurred specially in young children whose immature blood-brain barrier allowed penetration into the CSF of thiazolidine carboxylic acid, later metabolized locally into the strongly irritant compound formaldehyde. In view of its toxicity, the drug should never be administered to young children. The usual measures to prevent intoxication should be applied and in case of overdosage the patients should be admitted to hospital for observation. Long-lasting anti-epileptic treatments should be avoided.

The temporal pharmacokinetic (blood) and neuropharmacokinetic (cerebrospinal fluid, CSF) interrelationship of phenytoin was studied after acute and during chronic (up to 5 days) intraperitoneal administration of phenytoin (30, 50 or 100 mg/kg) using a new freely behaving rat model. After administration, phenytoin rapidly appeared in both serum (Tmax mean range 0.15-0.38 h) and CSF (Tmax mean range 0.9-1.4 h), suggesting ready penetration of the blood-brain barrier. However, transport across the blood-brain barrier may be rate limiting since whilst phenytoin concentrations rose dose dependently in serum, CSF concentrations did not. Further, the divergence between the blood and CSF compartments increased with chronic dosing. Cmax, AUC and t1/2 values for serum increased non-linearly, suggestive of accumulation kinetics. Based on these data, high initial phenytoin blood concentrations are essential if phenytoin entry into the brain is to be facilitated, and this may be important in studies of phenytoin in animal models of status epilepticus.

A previously healthy 22-month-old boy presented in status epilepticus with high fever. He was comatose, with upper respiratory-tract infection. The seizures responded to anticonvulsant therapy. The boy's temperature returned to normal within 24 hours and he recovered slowly from his encephalopathy. On the third hospital day, he exhibited the characteristic rash of reseola infantum. Acute infection with human herpes virus 6 (HHV-6) was established serologically by enzyme immunoassay. HHV-6 DNA was not detected by polymerase chain reaction in CSF or serum at the onset of illness, but was found three months later in the child's saliva. The pathogenesis of the patient's encephalopathy is discussed. It is concluded that HHV-6 infection should be considered in infants and young children with febrile status epilepticus.
