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.

Psychogenic seizures can mimic convulsive epilepsy and with repetitive attacks, iatrogenic complications from aggressive treatment of status epilepticus can occur. We studied neuropsychiatric features of 20 patients in whom psychogenic seizures were intractable and at times continuous. Nineteen of 20 patients seen were female, and all but one were under 40 years of age. All had convulsive attacks resistant to various medications, normal neurological examinations, and negative imaging studies and electroencephalograms (EEGs). Sixteen had previous evidence of epilepsy and the other four had epileptic relatives. Seizures were atypically prolonged, included back arching and pelvic thrusting, and persisted despite intravenous diazepam and therapeutic phenytoin and phenobarbital levels. Seizures terminated spontaneously in five, were stopped by suggestion in four, and persisted until respiratory arrest or elective intubation in 11. Ten patients had conversion disorder, six borderline or mixed personality disorder and four mental retardation. Fifteen had had some precipitating stressor and the remainder had histories of exhibiting attention-seeking behaviour. Nine of 10 patients with conversion disorder had 'conversion V' Minnesota Multiphasic Personality Inventory (MMPI) profiles, while personality disorder patients had elevation of several psychopathological scales. Patients with conversion disorder gradually improved with anticonvulsant discontinuation, while retarded individuals were helped by behaviour modification, situational change or neuroleptics. Personality disorder patients continued to have attacks and eventually discontinued follow-up. Clinical evidence of non-epileptic seizures includes clinical atypicality and long duration, exacerbation by medications and frequent attacks despite normal examination and studies.(ABSTRACT TRUNCATED AT 250 WORDS)

We studied the clinical course and seizure prognosis of 126 children with complex partial seizures regularly followed up for more than 4 years in our clinic. Clinical and EEG features of 63 seizure-free patients were compared with those of 63 patients with persistent seizures. The features contributing to poor prognosis were 1) mental retardation, 2) a history of status epilepticus and 3) abnormal basic rhythm in EEG. CT abnormality, a history of febrile convulsions (FC), the clustering of seizures and association with other types of seizures did not influence prognosis. We divided the patients into four groups according to the evolutionary pattern of seizure discharges: Group A, 55 (43.7%) patients with spike focus always fixed in the same region; Group B, 20 (15.9%) patients with wandering foci; Group C, 10 (7.4%) patients with multifocal spikes; and group D, 41 (32.5%) patients with no focal discharges. There was no difference in seizure prognosis among these four groups, but the patients with a focus in the anterior temporal region in Group A evidenced the worst prognosis.

Of 580 epileptic children, 353 males and 227 females, seen at the Paediatric Neurology Clinic of the University of Nigeria Teaching Hospital Enugu, from 1985 to 1987, 18 per cent were mentally retarded, a much higher prevalence rate than in the general population. Nine different seizure types were seen, with generalized tonic-clonic seizures (grand mal) leading in frequency. The highest incidence of mental retardation occurred among the children with infantile spasms (51 per cent). For all the seizure types, there was a long delay in seeking medical attention (mean interval, 1.7 years). The mean interval for epileptics with mental retardation was even higher (2.77 years). Factors found to increase the chances of an epileptic child having mental retardation include episodes of status epilepticus, early age at onset of seizures, and long delay before presentation to hospital for treatment. There is need for increased efforts aimed at the elimination of these factors and also for a well organized programme to educate the population about the nature of epilepsy, and the importance of compliance with the treatment schedule.

This study reports the neonatal aspects and prognosis of seizures observed in 71 neonates from 1.3. 1980 to 30.6 1981. Forty-five were full-term, 26 preterm babies. Twenty-one children had status epilepticus (SE), 50 isolated crises (IC). An etiology was found in 68 cases. Acute fetal distress (AFD) was observed in half of the cases. AFD and intracranial hemorrhages represented 62% of the etiologies in term babies, 42% in preterm. Fifteen children died in the neonatal period. The outcome of the 56 survivors was followed until at least two years of age. Forty-one children were neurologically normal; 15 were not: 9 had a cerebral palsy, 12 a mental retardation, 1 was deaf, 4 were epileptic. Sequelae occurred in 24.3% of term, 31.6% of preterm survivors (p less than or equal to 0.01). The outcome was normal in 8 out of 15 living children with SE (53%), in 32 out of 41 (78%) with IC (p less than or equal to 0.01). The prognosis of hypoxic-ischemic seizures was good if crises lasted less than two days. Treatment was discontinued as soon as possible, during the days following the end of the crises and the recovery from the initial disease, without adverse effects. Convulsions following obstetrical abnormalities were less frequent, and the prognosis was better in premature babies than in previous studies.

A total of 482 patients who had had one or more seizures in the first year of life were followed for at least five years (most for more than 10 years). The patients were divided into four groups: febrile convulsions, infantile spasms, status epilepticus and 'other'. Of those with febrile convulsions, 62 per cent developed normally, compared with 14 per cent in the group with infantile spasms, 15 per cent with status epilepticus, and 24 per cent in the 'other' group. Findings on recurrent seizures, epilepsy and mental retardation and/or neurological abnormalities are also reported. Epilepsy developed equally frequently among those with partial and with generalised seizures, but the former more frequently became mentally retarded. The effects of severity of seizures and other factors are discussed. In general, this research confirmed the grave prognosis after seizures during the first year of life, and not only for West syndrome and status epilepticus. The outcome was more favourable when the seizures were cryptogenic or febrile, isolated, with onset in the second six months, generalised, and when the EEG was normal between seizures.

Cerebral cortical dysgenesis (CD) is a heterogeneous disorder of cortical development and organization commonly associated with epilepsy, with a variety of subtypes. We reviewed the clinical, EEG and neuroimaging features in 100 adult patients with CD. There were 39 men and 61 women with a median age of 27 years (range 15-63 years). All patients were referred because of medically refractory epilepsy. Median age at seizure onset was 10 years (range 3 weeks to 39 years); in 30 patients, onset was in adulthood. The epilepsy was classified as generalized in 16 patients and localization-related in 84. Of the latter, the epileptic syndromes in decreasing frequency were frontal (32%), temporal (31%), parietal (14%) and occipital (7%). Only 15% of patients had a history of status epilepticus. Prenatal/perinatal problems were reported in 32 patients but these were severe in only four: exposure to drugs (three) and infection (one) during the first trimester. Delayed developmental milestones were seen in 10%, mental retardation in 9%, additional congenital abnormalities in 4% and neurological deficits in 14% of patients. Diagnosis of CD was based on neuroimaging in 70, pathology in four and both methods in the remaining 26. The following subcategories were identified: agyria/diffuse macrogyria (four patients), focal macrogyria (16), focal polymicrogyria (one), focal macrogyria/polymicrogyria associated with a cleft (11), minor gyral abnormalities (seven), subependymal grey matter heterotopia (20), bilateral subcortical laminar grey matter heterotopia (eight), tuberous sclerosis (five), focal cortical dysplasia/microdysgenesis (seven) and dysembryoplastic neuroepithelial tumours (DNT) (21). Sixty-eight percent of patients had normal CT and 19 out of 36 patients had normal previous conventional MRI. MRI-based hippocampal volume measurements in 47 patients revealed ratios (smaller: larger hippocampus) of < 0.90 in 16, 0.90-0.94 in 14 and > or = 0.95 in 17 patients. EEGs were normal in only five patients. Alpha rhythm was preserved in 78 patients, including one patient with bilateral posterior macrogyria. Localized polymorphic slow activity was present in 43 patients. Five of 68 patients with focal/unilateral CD had only bilateral independent/synchronous spiking and 14 out of 32 with diffuse/bilateral CD only focal/unilateral spiking. In 60 patients with nondiffuse CD or with abnormal gyration or DNT, the epileptiform abnormalities were less extensive than coextensive with the lesion in 28, more extensive than and overlapped the lesion in 18 and remote from the lesion in five; nine patients did not have epileptiform abnormalities. There was poor correlation between the epileptic syndromes and EEG abnormalities and the location/extent of CD as defined by MRI and pathology.(ABSTRACT TRUNCATED AT 400 WORDS)

We report 5 pediatric patients (2 male, 3 female; age range: 4-8 years) with complex partial status epilepticus (CPSE). Four patients had previous illnesses and mild motor or mental retardation. In 2 patients, CPSE was induced by inappropriate management or selection of antiepileptic drugs. Clinical features varied and automatisms were observed in 3 patients. In 1 patient, decreased physical tone with syncope and impaired consciousness with amaurosis were observed. The episodes of CPSE were continuous in 3 patients and recurrent in 2 patients. In 4 patients, ictal electroencephalographic (EEG) findings, including video-EEG analyses of 3 patients, demonstrated persistent focal epileptic features. Intravenous diazepam abolished CPSE in 3 patients with brief periods of definite EEG localizations remaining. In 4 patients, seizure prognoses were favorable after appropriate treatments; in 1 patient, seizures were intractable even after antiepileptic drug administration.

The effects of rapid rectal diazepam introduction (DZP test) were investigated in 43 patients (age range 5 months-14 years) with electrical status epilepticus (ESE) undergoing EEG monitoring. A remission of the paroxysmal activity was obtained in 58% of cases, a negative response in 42%, particularly in hypsarrhythmic patterns. DZP test responders were aged over 12 months with organized paroxysmal EEG patterns, in particular with ESE during sleep (ESES). The patients who responded to the DZP test underwent short cycles (3-4 weeks) of relatively high dosage DZP (0.5-0.75 mg/kg). The response to treatment was positive in 64%, particularly in ESES conditions. 56% of responders to the DZP test but not to DZP therapy (five out of nine patients) presented a significant mental retardation; maturational factors were also likely to be present.

A previously healthy 8-month-old girl developed exanthem subitum and acute encephalopathy with status epilepticus, quadriplegia and bilateral abducens nerve palsies. Human herpesvirus-6 DNA was found in the cerebrospinal fluid by the polymerase chain reaction at the acute stage. Cranial computed tomography showed low density areas in the thalami and in the cerebellar and abducens nuclei. The distribution of the lesions was consistent with acute necrotizing encephalopathy. As for the thalamic lesions, a T2 weighted magnetic resonance image on the 24th day of the illness demonstrated low signal intensity surrounded by high intensity; 99mTc-ECD SPECT showed hypoperfusion, which suggested irreversible tissue damage. The patient is now 1 year 6 months old and has spastic quadriparesis with mental retardation and abducens nerve palsies.
