The authors studied 286 patients with epilepsy with disease onset past the age of 20 years (176 males, 110 females) from the urban and rural populations. In 57% of cases the aetiology of epilepsy was undetermined. Among the known aetiological factors head trauma accounted for 15.5% of cases, inflammatory processes in the central nervous system for 4.5%, alcoholism for 7%, vascular lesions for 6%, tumours for 5.2%, degenerative and atrophic changes for 1.5%. Over 40% of patients had had attacks for up to 15 years and over 18% for over 20 years. In 80% of cases grand mal seizures occurred, and in 33% of these cases more than 12 attacks occurred annually. Six cases of status epilepticus were observed with 2 deaths. The attacks were precipitated by menstruation, alcohol abuse, infection, stressed, television watching. Among the signs accompanying or following the seizures tongue biting and urination prevailed. Neurological signs were demonstrated in 21% of cases, encephalopathy in 65%, other psychic disturbances in 9.5%. Systematic treatment was received by 75% of the patients (over 80% in urban population), and therapy with multiple drugs was most frequent. Drug-resistant epilepsy was found in 34% of cases. The patients from the rural population had a lower educational level and had more children. About 70% of the patients were in employment.(ABSTRACT TRUNCATED AT 250 WORDS)

Fifteen newborns with neonatal status epilepticus were prospectively identified from a protocol of convulsion in the newborn, at the neonatal intensive care unit. The mean postnatal age was 7.1 days, with fourteen full term babies and one premature. Previous complications during childbirth existed in twelve infants. The principal etiology associated was hypoxic-ischemic-encephalopathy, and four patients died. In thirteen cases the antecedent of subtle seizures existed; only in four cases was status epilepticus suspected. Difficulty in clinical recognition makes it necessary to perform an EEG on each newborn with risk factors, abnormal neurological manifestations, or with prolonged and or repeated hypoxic perinatal antecedents.

Convulsions or status epilepticus in 11 infants after pertussis vaccination are reported. In 3 cases grand mal epilepsy persisted and 2 children developed infantile epileptic encephalopathy (Lennox syndrome). On the basis of our own experience, the incidence of seizures approximates 1:4800 infants vaccinated or 1:12 800 vaccinations. According to a recent prospective study from the USA, the incidence of seizures may be closer to 1:600 infants. Since there is a significant difference between the incidence of spontaneous fits in children of the same age group and the incidence after vaccination, a causal relationship between the seizures and vaccination appears to be confirmed. The following conclusions are drawn from these observations: 1. In view of the usually benign course of whooping cough today, current vaccination against pertussis is hardly satisfactory. Improvement of the available vaccines is an urgent necessity. The protection should include the population most at risk, i.e. infants during the first few months of life. 2. Parents should be better informed about the risks involved in pertussis vaccination. 3. Booster inoculations should be abandoned. 4. Health authorities should decide whether the current pertussis vaccination program should be continued. 5. Complications following vaccination should be registered at a national centre.

Five cases of encephalopathy due to intravenous penicillin treatment (penicillin G sodium in 4 cases, oxacillin in 1) are reported in 5 uraemic patients. The first abnormalities noted were decreased consciousness and myoclonic jerks (3 cases), followed by seizures and coma (2 cases). Lumbar puncture and cerebral computed tomography gave normal results. Electroencephalograms showed diffuse sharp and slow activities over the brain areas. The diagnosis was confirmed by the high blood levels of the penicillins. Three patients recovered after discontinuation of the drugs; two patients died in status epilepticus and coma resistant to all treatments.

A 16-year-old female presented with clinical, morphologic and molecular features of mitochondrial myopathy, encephalopathy, lactic acidosis and stroke-like episodes (MELAS). Her early development was normal. Starting from the age of 14 years, she experienced recurrent episodes of headaches, with vomiting, seizures, transient right hemiparesis and decreased visual acuity. Computed tomographic brain scans revealed calcification in the bilateral basal ganglia. Biopsied specimens from her left biceps brachii and rectus femoris muscles revealed ragged-red fibers and strong succinate dehydrogenase-reactive blood vessels. Electron microscopy revealed paracrystalline inclusions in muscle mitochondria. Analysis of mitochondrial DNA (mtDNA) from blood, hair follicles and muscle specimens showed an A to G point mutation at nucleotide position 3,243 in the transfer RNA(Leu(UUR)). The proportion of mutant mtDNA in the patient's blood was 43%, in hair follicles 62% and in muscle 82%. The patient was followed up for 4 years and had progressive mental deterioration and died of an episode of status epilepticus. This patient and 5 other MELAS patients reported in Taiwan are compared.

Patients with mitochondrial disease may present to the Intensive Care Unit (ICU) with a variety of neurological and general medical disorders. Eleven patients were admitted to a neurological ICU between 1970 and 1992 because of respiratory insufficiency, status epilepticus and/or metabolic encephalopathy associated with mitochondrial disease. Respiratory impairment occurred in eight patients and was associated with nocturnal hypoventilation due to respiratory muscle weakness, aspiration due to bulbar weakness and abnormalities of central control leading to a reduced CO2 drive, irregular respiratory patterns and sleep apnoea. Seven patients received continuous respiratory support during the acute illness; three were subsequently weaned to domiciliary ventilation, and four died. Five patients had stroke-like episodes, which in two were recurrent. Four patients developed tonic-clonic grand mal epilepsy associated with myoclonic fits (2 patients), absences (2), focal fits (1) and status epilepticus (2). Encephalopathy was associated with recurrent lactic acidosis (2 patients), cardiac failure (2), hyponatraemia (2), renal abnormalities (3) and complete heart block (1). Although rare, mitochondrial disease should be considered in any patient with unexplained respiratory failure, intractable epilepsy, lactic acidosis or recurrent stroke.

A 44-year-old man suffered a severe anoxic encephalopathy with rapid fatal outcome. His EEG prior to expiration showed a burst-suppression pattern (BSP) with occurrence of two previously unreported clinical features: spontaneous chewing movements during the burst and tonic posturing during the suppression phase. In coma the appearance of BSP in the EEG commonly implies a severe anoxic/metabolic insult to the brain with a grave prognosis. The pattern is considered to be interictal, except in cases presenting with myoclonic status epilepticus. Subtle intermittent movements of the eye, mouth and cardiovascular rhythm are uncommon and it is unclear whether these are epileptic events or not. This case indicates that the suppression phase can also have associated clinical signs.

Midazolam is a short-acting water soluble benzodiazepine that has been used with an increasing frequency in the last years. Although there are reports on its use in status epilepticus, there is none in the neonatal period. A pre-term (35 w) AGA newborn infant with a severe hypoxic-ischemic encephalopathy secondary to grade III hyaline membrane disease developed status epilepticus in the first 6 hours of life and was successfully treated with midazolam after phenobarbital and phenytoin failed to achieve seizure control. Dosage schedule was 0.2 mg/kg IV, followed by continuous infusion of 0.025 mg/kg/h. Midazolam is an effective drug for neonatal status epilepticus and more experience should accumulate before it can be routinely employed in the neonatal period. This case shows that it is a possible option before using more dangerous drugs, such as thionembutal.

The prognostic value of early neonatal continuous electroencephalographic recordings in hypoxic ischaemic encephalopathy was evaluated. Thirty seven full term infants with hypoxic ischaemic encephalopathy were studied. The electroencephalogram (EEG) was recorded using four or eight channel Oxford Medilog recorders and was started as soon as possible after birth. The recordings were initially visually analysed and divided into four categories: three in relation to the grade of discontinuity of the background activity (continuous, discontinuous, and maximum depression) and an additional fourth category to include status epilepticus. The EEGs with discontinuous activity were then analysed by computer to obtain a more objective assessment of discontinuity. The results were related to neurological outcome. Continuous background activity was associated with a normal outcome in all but the three infants who had continuous, but asymmetrical EEGs and who developed contralateral hemiplegia. In the eight infants with discontinuous activity, the outcome appeared to be related to the grade of continuity and the presence of clear convulsions on the EEG. The 10 infants with maximum depression and status epilepticus had severe impairment. These preliminary results suggest that continuous recording of EEGs could be used routinely in term infants with hypoxic ischaemic encephalopathy. Computer analysis can improve the value of this technique, allowing the identification of infants who might benefit from early therapeutic intervention.

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.
