A 15 years-old girl with no previous history of epilepsy or neurological disease presented three types of epileptic symptoms the same day: 1) clusters of rhythmic myoclonus of the left hemiface; 2) episodes of painful paresthesias of the left arm followed by secondary generalised seizures; 3) episodes of elementary visual hallucinations of the right hemifield. She had several seizures each hour and some were recorded. There were no EEG abnormalities during the facial myoclonus but rapid rhythms were seen during the sensory and visual partial seizures on the right parietal and left occipital lobes. There was no fever and no drowsiness. The CSF tap showed pleocytosis. Serological studies indicated recent mumps. The drugs were initially inefficient. The seizures disappeared after a month. The drugs were stopped after three months and the seizures had not relapsed after a one year's follow-up. Though there were no other sign of encephalitis, we believe that episode of multifocal seizures was due to mumps encephalitis.

Intramuscular injection of sodium penicillin in roach (Rutilus rutilus) caused delayed habituation of arousal responses to repeated presentation of the onset of illumination or of a 'tap' stimulus. Topical application of aluminum hydroxide to the telencephalon of roach had a similar effect but was shown, also, to induce electroencephalographic seizures, in which the EEG amplitude was elevated from 4-20 times its normal level. Both treatments caused intermittent, abnormal 'weaving' behaviour and sporadic, violent, uncoordinated motor activity. In goldfish, Carassius auratus, topical application of aluminum hydroxide also caused delayed habituation of quantitatively measured, cardiac arousal responses to a moving shadow stimulus, compared to controls. This delayed habituation was, however, largely a result of the elevated magnitude of these arousal responses. The results are discussed in relation to brain mechanisms normally operative during arousal which may be hyperactive in epilepsy.

In the course of a schizophrenic episode a woman drank a large amount of tap water. She was found nearly unconscious in her room and was admitted to the clinic. Very low sodium and potassium values in the serum were indicative of water intoxication. During hospitalization she also suffered from several convulsive seizures. After replacement of electrolytes she recovered within 12 to 17 h. This case report demonstrates that water intoxication should also be considered in cases of suspected poisoning with other substances such as drugs. In all these cases an electrolyte status is indicated.

A case of astroblastoma in a male newborn baby was reported. He has been suffered from convulsive seizures from six hours later after the birth, not controlled by the anticonvulsants, and lumbar tap revealed bloody cerebrospinal fluid. He had no response against the noxious stimuli and left clonic hemiconvulsion, and showed anisocoria, left pupil was dilated. Right BAG showed a large space occupying lesion in the right frontal lobe. Operation was performed eighteen hours after the birth. Right frontotemporal craniotomy revealed reddish-grey, soft tumor in the right frontal lobe infiltrating into the parietal and temporal lobe of the same side and frontal lobe of the left side. Right frontal lobectomy was performed. He had cardiac arrhythmia after the operation and died next day. Autopsy was not permitted. Histologically tumor tissue showed abundant vessels and perivascular pseudorosettes, and electron micrograph revealed glial filaments in the tumor cells. Histological diagnosis was astroblastoma.

We have studied prospectively 39 patients receiving a course of electroconvulsive therapy (ECT) for major depressive disorder; they were allocated randomly to receive either propofol or methohexitone for anaesthesia. Recovery after the third ECT treatment was assessed by finger tap and digit symbol substitution tests at 15, 30, 45, 60 and 90 min after induction. Seizure duration (median (interquartile range)) was shorter with propofol (24 (10) s) than methohexitone (29 (17) s) (P = 0.08). There was no significant difference in psychometric recovery for drug type, duration of the seizure or initial severity of depression. These results suggest that the more rapid recovery rates noted with propofol in other procedures are not evident after electrically induced seizures.

The clinical courses of 8 term infants with focal cerebral infarction or neonatal stroke were studied to determine whether such infants can be identified by current markers of perinatal distress, and whether changes in cerebral blood flow velocity (CBFV) occur during the acute phase of the disease. CBFV was measured from the middle cerebral artery (MCA) and anterior cerebral artery (ACA) utilizing duplex Doppler. Seven of the 8 patients required no resuscitation in the delivery room; 1 infant required brief bag and mask ventilation. No infant had evidence of severe fetal acidemia (i.e., cord pH < 7). All 8 infants were initially admitted to the newborn nursery. Infants were identified on the basis of abnormal clinical findings observed during the first 48 hours: seizures (n = 6) and hypotonia and apnea (n = 2). Serum electrolytes, calcium, magnesium, and glucose levels were normal, and the sepsis evaluation including a spinal tap was sterile in all patients. Neuroimaging revealed nonhemorrhagic left focal MCA infarction (n = 6) and right focal MCA infarction (n = 2). Duplex Doppler demonstrated transient ipsilateral decreases in CBFV as compared to the contralateral unaffected side at clinical presentation in 4 infants. In 2 of these infants the decrease in CBFV involved both the MCA and ACA, and in 2 infants, only the MCA vessels. These side-to-side differences were not present at subsequent CBFV measurements. The data indicate that infants who develop neonatal stroke cannot be distinguished from infants who do not develop the lesion by current markers of perinatal distress.(ABSTRACT TRUNCATED AT 250 WORDS)

Bismuth subsalicylate preparations are over-the-counter products for gastrointestinal complaints. Bismuth toxicity causes delirium, psychosis, ataxia, myoclonus, and seizures and is reversible over several weeks or months, when bismuth intake is stopped. We report a 54-year-old man with a 6-week history of progressive confusion and memory difficulty and a 2-3-week history of involuntary movements and gait impairment. His encephalopathy was further characterized by marked multifocal myoclonic jerks, coarse postural tremors, postural instability, and gait ataxia. He gradually improved. Extensive toxic, metabolic, and infectious workup demonstrated bismuth toxicity. Spinal tap and brain magnetic resonance scan were normal. Electroencephalography showed bihemispheric slowing. As his encephalopathy cleared, he reported using bismuth subsalicylate long term (daily intake of 8 oz). Bismuth levels 5 weeks after cessation of bismuth were elevated and normalized after 12 weeks. He followed a typical course for bismuth toxicity with subacute progressive encephalopathy and gradual recovery. Creutzfeldt-Jakob was strongly considered due to his rapidly progressive encephalopathy, multifocal myoclonus, and ataxia. Due to its rarity, bismuth toxicity is often overlooked. We hope this presentation will increase recognition of bismuth toxicity. We believe more detailed labeling of bismuth products is needed to avoid similar toxicity from this readily available product.

Inbred mouse strains differ in sensitivity to a first dose of nicotine and in the development of tolerance to nicotine. The experiments reported here used six inbred mouse strains (A, BUB, C3H, C57BL/6, DBA/2, ST/b) that differ in sensitivity to an acute challenge dose of nicotine to determine whether differences in oral self-selection of nicotine exist. Animals were presented with solutions containing nicotine or vehicle (water or 0.2% saccharin) and their daily intake of the two fluids was measured for 4 days starting with a 10 micrograms/ml nicotine solution. This was followed by sequential 4-day testing with 20, 35, 50, 65, 80, 100, 125, 160 and 200 micrograms/ml nicotine solutions. The strains differed dramatically in their self-selection of nicotine and in maximal daily dose (mg/kg); the rank order of the strains was C57BL/6 > DBA > BUB > A > or = C3H > or = ST/b for both the tap water and 0.2% saccharin choice experiments. Correlations between nicotine consumption and sensitivity to nicotine, as measured by a battery of behavioral and physiological responses, were also calculated. Strain differences in nicotine intake were highly correlated with sensitivity to nicotine-induced seizures. As sensitivity to nicotine-induced seizures increases, oral self-selection of nicotine decreases. This finding may suggest that this toxic action of nicotine serves to limit intake.

Subdural empyema, a collection of pus in the space between the dura and arachnoid, is a rare type of intracranial infection. We report on 23 patients, aged 8 months to 70 years, with subdural empyema who were treated in our clinic between 1989 and 1994. The sources of subdural empyemas were meningitis in five patients, middle ear in five, trauma in four, paranasal sinus in three, complications of surgery and subdural tap in four, and unknown in two patients. The common presentations were headache, focal neurologic deficit, fever, vomiting, seizures, and neck stiffness. Diagnosis was achieved by computerized tomography and neurologic examinations in all cases. Treatment was effected by burr hole or small craniotomy with catheter drainage, and antibiotics were administered to all patients. The mortality rate was 8.7%; the remaining patients made a good recovery without sequelae. We therefore recommend burr hole with catheter drainage plus antibiotics as a method of treating subdural empyema.

Febrile convulsions can cause extreme anxiety to parents. Factors associated with parental anxiety and its relief during and after admission of their child for simple febrile convulsions were studied by questionnaire. Of the 70 parents approached 46 responded (66%), all of whom reported feeling anxiety. Factors directly associated with parental anxiety were lack of knowledge regarding the management of seizures and the performance of a spinal tap or EEG. There was no correlation between a previous seizure in the same child or in a first-degree relative and a decrease in anxiety in the present seizure. Hospital admission of the child yielded no relief of anxiety in 27.3% and some relief in 34.1%. Staff activity was insufficient regarding parental instruction in handling the child in the event of a recurrence. About two-thirds of the parents wished to continue neurologic follow-up after discharge, and about one-half preferred that the child be treated with anticonvulsants. Our findings show that a very intensive effort is required to relieve parental anxiety after febrile convulsions. It is suggested that routine parental preventive education in this area be conducted in well-baby clinics.
