The purpose of the study was to identify the clinical symptomatology of children with focal sharp waves of genetic nature. Genetic determination was assumed if the EEG of at least one sib revealed typical focal sharp waves. Forty-one probands (27 boys, 14 girls) and their 44 sibs showed a broad spectrum of different seizure types of focal origin including so-called atypical benign partial epilepsy (pseudo-Lennox-syndrome) and febrile convulsions. Numerous cases showed psychomental retardation or selective deficits of development. The classical syndrome of rolandic seizures with normal psychomental development and normal neurological findings was present in only a few cases. Similarly, EEG findings were quite variable. Rolandic sharp wave foci alone were found in only 22% of the probands. The remainder had foci in other regions (17%), or multiple foci (61%). Depending on age at first seizure, 42%-79% of the seizure-affected probands and 50% of the affected sibs showed generalized heritable EEG traits such as 4-7/s rhythms, generalized irregular spikes and waves, and/or photoparoxysmal response. Three pairs of monozygotic twins were concordant for the special type of EEG findings, two of them also for clinical symptoms.

Selective episodic prophylactic home treatment with rectal diazepam in children with febrile convulsions should reduce the risks of permanent long term anticonvulsive drug therapy. To evaluate this approach and its side effects, selective prophylaxis (rectal diazepam, 0.6 mg x kg at 8 to 12 hour intervals) was given to 15 children with previous febrile convulsions whenever their axillary temperature raised to 38 C degrees or over. They were followed up for a mean of 7.73 months (range 3 to 20 months). In a total of 27 febrile episodes only 2 seizures occurred, each to a different patient and in both cases when treatment was inadvertently withheld. No recurrences were observed in the remaining 13 patients involving 25 treated febrile crisis. The small number of patients precluded evaluation of the effects of risk factors in recurrence rates. Mild and transient collateral effects were detected in 46.6% patients and in 32.0% of the observed febrile periods. In spite of the small number of patients and short follow-up period these results suggest, that episodic, non permanent, treatment with rectal diazepam is an appropriate alternative to traditional continuous oral anticonvulsive therapy for children with febrile convulsions.

We examined the clinical significance of bisynchronous spike-wave complexes which appear in EEGs of some patients with focal spikes in one or both temporal lobes. Few features distinguished patients with bisynchronous spike-waves from those with only focal temporal spikes: a higher incidence of patients with more than two grand mal seizures a year (43 vs. 7%) and a younger age at last recording (22.5 vs. 28.3 years) were the only statistically reliable factors. Proportion of patients with complex partial seizures (CPS) (100%), age of CPS onset, incidence of febrile convulsions, intellectual level, and normal neurologic examination were features common to the two groups. In contrast to other studies which did not exclude influencing variables such as extratemporal spike foci, our group with bisynchronous spike-waves fared equally well after temporal lobectomy as did patients with temporal spikes alone. All 6 patients with spike-waves obtained a reduction of at least 50% in seizure frequency and 5 of the 6 (83%) had a greater than 90% reduction. Sixteen of 17 patients (94%) without spike-waves had a reduction of at least 50% and 14 of the 17 (82%) had a greater than 90% reduction of seizures.

Forty patients with partial epilepsy that began before they were aged 3 years were recorded at the Centre Saint-Paul between 1981 and 1986 with a follow-up ranging from 1 year 9 months to 20 years. We analyzed the following data: age at onset, clinical features of seizures at onset and during the follow-up period, ictal and interictal EEG features, etiologic circumstances, evolution of the epilepsy, and psychomotor development. The age of onset was mostly between 2 months and 2 years (more than two thirds of cases). Most had partial symptomatic epilepsy. In nine cases, epilepsy was preceded by febrile convulsions. Seizures at onset were of the following type (in order of decreasing occurrence): unilateral seizures, complex partial seizures, elementary partial seizures, and other seizures, often difficult to classify. A few patients with infantile spasms associated with focal or multifocal EEG abnormalities, differing from West's syndrome, were included in this study. We discuss the problem arising from the classification of infantile seizures and epilepsies.

We randomized 31 children with a 1st afebrile unprovoked seizure to receive carbamazepine (CBZ) or no medication for 1 year or until the time of a 2nd seizure. All seizures had a focal onset or were generalized tonic-clonic. Overall, 2/14 randomized to CBZ and 9/17 with no medication had a recurrent afebrile seizure. Compliance with CBZ was excellent in 12/14, but noncompliance may have contributed to 1 of the recurrences with CBZ. Four discontinued CBZ because of side effects. Two additional children taking CBZ had a febrile seizure. Thus, only 6/14 taking CBZ had a year completely seizure-free with no unacceptable medication side effects. Of those taking no medication, 2 had a febrile recurrence, and 7/17 had a year completely-seizure free. Side effects and febrile recurrences may limit the value of CBZ for some children, although CBZ appears to reduce significantly recurrences after a 1st afebrile seizure.

To evaluate the risk of neurologic events after vaccination with diphtheria-tetanus-pertussis (DTP) vaccine, we used data from the Centers for Disease Control Monitoring System for Adverse Events Following Immunization to compare the family history of convulsions in persons reporting neurologic events with that in persons reporting nonneurologic events; these events have an onset within 3 days of immunization with DTP vaccine, given either alone or with oral poliovirus vaccine. Persons reporting neurologic events were 6.4 times more likely to report a prior personal history of convulsions than those reporting nonneurologic events (95% confidence interval 4.7 to 8.8), and were 2.4 times more likely to report a history of convulsions in first-degree family members, that is, siblings or parents (95% confidence interval 1.7 to 3.4). Similar risks were noted for subgroup analyses controlling for type of event (febrile vs nonfebrile convulsion), age at immunization, source of report, number of previous doses of DTP vaccine, and day of onset. Because the Centers for Disease Control monitoring system receives reports on a nonrandom sample of all adverse events after immunization, selection bias could not be ruled out. On the basis of these data, we conclude that children with a family history of seizures are at increased risk of neurologic events, primarily febrile convulsions, after DTP vaccination. However, this increase in risk may reflect a nonspecific familial tendency for convulsions rather than a specific vaccine effect. Considering the rare occurrence of neurologic events after DTP vaccination, the generally benign outcome of febrile convulsions (which make up the majority of these neurologic events), and the possible increased risk of pertussis in the general population if the estimated 5% to 7% of persons with a first-degree family history of convulsions were exempted from pertussis vaccination, we further conclude that a history of convulsions in siblings or parents should not be a contraindication to pertussis vaccination. Special care in the prevention of postvaccination fever may be warranted in children with a family history of seizures.

Using spectral analysis data of the previous study a trial was undertaken to develop criteria for diagnosis and risk assessment of epilepsy. To the spectral parameters++, differentiating groups of epilepsy and normals, the diagnostic weights from 1 to 10 were attributed, according to the probability "p" from 0.01 to 0.001 using "t" criterion. Sums of the weights formed "epilepsy indexes" (EL) for each normal and patient. From these EI confidence intervals for p less than 0.034 and less than 0.003 were obtained. The criteria were checked on a mixed group of patients differing by the degree of epileptic charge. Positive EI were found only in the patients with high risk of epilepsy (febrile convulsions and epileptic siblings) and in patients with actual epileptic seizures, corresponding in the latter mostly to p less than 0.003.

Cerebrospinal fluid/serum lactic acid was prospectively assayed in 42 patients with febrile convulsions. Patients were divided into two groups for analytical purposes. Those with brief febrile seizures (30 patients) and the remaining 12 patients had prolonged febrile seizures. CSF and serum lactic acid values were within normal range in patients with brief seizures while elevated values were obtained in patients with prolonged seizures. The mean CSF lactic acid on admission was significantly higher (P less than 0.001) in patients with prolonged seizures than corresponding values in those with brief seizures. Mean serum lactic acid on admission was also significantly higher in patients with prolonged febrile seizures compared to the corresponding mean value in patients with brief seizures (P greater than 0.001). Patients who recovered with neurological deficits had significantly higher CSF lactic acid on admission (P greater than 0.001). Similarly 8 patients who had recurrent febrile convulsions had significantly higher CSF lactate on admission. It is suggested that measurement of CSF lactate can be used as a biochemical marker to identify children with prolonged seizures and those who are likely to have recurrent febrile seizures.

Febrile seizures are a common problem in young children. Most febrile seizures are benign in nature, although a small percentage of children may develop recurring febrile seizures or afebrile seizures. The approach to the management of this disorder varies widely from specialty to specialty despite the recent publication of studies that provide for rational treatment of febrile seizures. Most children do not need any treatment after a first simple febrile seizure. In certain children who are at risk for recurrent febrile seizures, rectal anticonvulsants should be considered for acute, short-term management. Long-term anticonvulsants should be reserved for patients who are unable to use rectal anticonvulsants or who have significant risk factors for the development of afebrile seizures.

The study was performed on a group of 91 children with their first febrile convulsion whose parents were then instructed in the use of rectal diazepam in the event of a further seizure. later, the families were periodically recalled for interviews. The aim was to study the acceptance and cooperation of the families, the psychological attitude and the relation between the findings and parents' educational level. At the end of the follow-up, 80% of the 91 families showed good cooperation and psychological benefits. There was no relationship between the findings at the end of the follow-up and families' educational level. Even in the presence of a favorable psychological attitude, recurrences of febrile convulsions were still a frightening experience for many parents.
