Twenty-eight post-injury states were assessed in 27 children (in one child two attacks occurred) aged 1-9 years. The states could be classed as so called benign posttraumatic encephalopathy. The mild head injury was followed after a latent period (proved in 22 attacks) of 5 min. to 14 hours by transient brain disorder (in 17 cases quantitative, qualitative and combined alteration in consciousness, in 7 children cortical blindness, in 2 epileptic seizure and in two brain stem disturbance). The duration of symptoms lasted 5 minutes to 48 hours. After recovery the children had no difficulties; the mean of follow-up was 3.3 years. The EEG showed predominantly a normal picture or only abnormal background activity of bioccipital slow waves. In the history and clinical picture we found after the attack most often perinatal abnormality and minimal brain dysfunction (15x, 57%) and various forms of migraine (4x, 16%). It indicates that in the pathogenesis of benign posttraumatic encephalopathy apparently an important part is played by pretraumatic cerebral affection.

The pattern of epilepsy and other convulsive disorders in 1,000 consecutive Saudi nationals is described. These disorders were common with a hospital frequency rate of 8 per 1,000. Men were more frequently affected than women and 60% of the patients were under 10 years old at the onset of their illness. The epilepsies were the commonest type (74%). Febrile convulsions (20%) presented mainly between the ages of one and five years. Isolated seizures (3%) and acute symptomatic convulsions (3%) were uncommon. In the epileptic group, generalised seizures (71%) were more frequent than partial (29%) and complex partial seizures occurred mainly in those above 21 years old. Absences (4%), infantile spasms (3%) and atonic seizures (3%) were uncommon. No specific etiology of the epilepsy was determined in the majority of the cases (63%). The identified major etiologic factors of the epilepsies were perinatal encephalopathy (21%), cerebral trauma (11%), sequelae of meningitis or encephalitis (2%), brain tumors (0.5%), and vascular lesions such as stroke and arteriovenous malformation. Perinatal encephalopathy accounted for 40% of the epilepsies in children less than 5 years old, and trauma for 20% of those above 20 years old. A family history of epilepsy in close relations was obtained in 23% of the cases, and the consanguinity rate among the parents was 53%. The high incidence of associated perinatal encephalopathy found in this study suggests that perinatal factors play a major role in the pathogenesis of epilepsy in Saudi Arabia. The high frequency of cerebral trauma was also striking. Although consanguinity of the parents appeared not to be a major factor in the genetics of convulsive disorders in this environment, it might have potentiated the tendency of familial aggregation of convulsive disorders in this community. Consanguinity may be an important factor in the production of some of these disorders but its precise role has not been determined.

One hundred and thirty four newborn children of 37 weeks' gestation age or greater, with evidence of hypoxic-ischemic encephalopathy following perinatal asphyxia and surviving through the neonatal period were prospectively studied. The study involved evaluation of clinical outcome and the presence of epilepsy associated with the EEG pattern in the neonatal period. The results prove that the presence of a burst suppression EEG pattern and a hypoactive/flat EEG are negative prognostic criteria. In presence of a focal or multifocal pattern it is difficult to establish a clear prognostic criteria. Last, in newborn children with a normal EEG; with a low amplitude register; with frequencies slow or with bilateral sharp waves transients, a good prognosis can safely be established.

A syndrome of pertussis vaccine encephalopathy was first reported 56 years ago. Analysis of the recent literature, however, does not support the existence of such a syndrome and suggests that neurologic events after immunization are chance temporal associations of neurologic conditions that occur in the target age group, even in the absence of immunization. Population-based studies do not prove a causal relationship with acute encephalopathy. There are no consistent neuropathologic findings suggesting a specific pathophysiologic process, and hypotheses concerning possible mechanisms of damage are not supported by reproducible studies in children. No acceptable animal model exists. There clearly is an increased risk of a convulsion after diphtheria-tetanus-pertussis immunization but no evidence that this produces brain injury or is a forerunner of epilepsy. Studies have also not linked immunization with either sudden infant death syndrome or infantile spasms.

We report 3 cases of epilepsy with bilateral occipital calcifications followed up for several years. These cases were compared with 21 published cases and were found to differ from the classical Sturge-Weber syndrome on several points: 1) the disease appeared around the age of 5 years and consisted of focal epilepsy without neurological or mental disorders; 2) the epilepsy was easy to control during 2 to 5 years. This was followed by a diffuse encephalopathy with severe, treatment-resistant epilepsy, Gerstmann's syndrome, optic ataxia, cerebellar syndrome and slow activity at EEG. It appears from these 3 cases that: 1) occipital calcifications may be unilateral at the onset of the disease; 2) visual evoked potentials are affected at a late stage, and 3) CT scans are of considerable value in the prognosis of benign epilepsy in childhood.

Epilepsy is a rare but possible manifestation of thyrotoxicosis. The patient reported here developed recurrent, generalized and focal seizures, as presenting symptoms of a thyrotoxic encephalopathy. Intercritic EEG records showed triphasic waves. Seizures and signs of encephalopathy disappeared and the EEG reverted to normal only after treatment of the thyroid hyperfunction. It is concluded that thyroid function should be evaluated in cases of otherwise unexplained encephalopathy with untreatable seizures and triphasic waves.

The clinical course of symptomatic epilepsy caused by intraventricular hemorrhage (IVH) in 7 preterm infants and hypoxic-ischemic encephalopathy (HIE) in 9 full-term infants were followed up for more than 2 years and 6 months. West syndrome was the first manifestation of epilepsy in 10 cases (IVH: 4, HIE: 6), and all 16 patients had severe neuropsychiatric deficits. Comparing with children without epilepsy, IVH grades III and IV, mechanical ventilation for more than 6 days and neonatal convulsions in the patients with IVH, and mechanical ventilation and neonatal convulsions in the patients with HIE, were significantly related to the risk of subsequent epilepsy. These findings suggest that the degree of brain injuries may be predictive of the development of epilepsy during infancy and early childhood in the patients with IVH or HIE.

We presented the experience at the Emergency Unit of the National Institute of Pediatrics with children with Status Epilepticus (SE). This series studied 70 patients, the greatest frequency was seen among infants (55%), followed by preschool children (17%). The most frequent type of SE was generalized tonic clonic (54%) also being the most critical. The simple partial status or epilepsia partialis continua was found to be another frequent variety. In newborns babies the most common type of SE was generalized tonic. Sixty percent originated as acute process, their main causes were central nervous infections, ischemic-hypoxic encephalopathy, intracranial hemorrhages and intoxications. The remaining 40% were due to chronic processes, the most important was secondary epilepsy. Among these children the main cause was the irregular use of antiepileptic drugs. Other factors were intercurrent infections with fever, head trauma and hyponatremia. Only 12.8% of the cases were idiopathic. Fifteen percent of the SE were successfully treated with diazepam; 44% with phenytoin plus phenobarbital, in 34.2% we used generalized anesthesia with thiopental. In 33% of the acute cases os SE there were sequelae, there were nine deaths (12.8%) all of them with serious illness of the central nervous system.

Below is report on our experience using a relatively new benzodiazepine as treatment for refractory epilepsy in 30 children. All of the patients had a severely fixed encephalopathy; 17 presented mixed epilepsy, 9 had Lennox-Gastaut syndrome and 4 others, West Syndrome. The seizures were totally controlled in 20% of the children; in a proportion superior to 75%, seizures were decreased in 46% of the patients. There were positive results in 6% of the cases and side-effects were seen in 13%. The usefulness of the clobazam as a co-adjuvant medication in the control of refractory epileptic seizures was demonstrated since the number of seizures decreased from 15 to 3 per day.

Two young males in their thirties are reported with a clinical history and examination indistinguishable from typical females with the Rett syndrome. Both had normal early development. The first patient had a regression by the end of the second year. He was late in walking, had prominent hand-wringing from the age of 4 years, and non-progressive dystonia from the age of 14 years. He is still ambulatory. Seizures which started at the age of 18 months have been easily controlled. The second patient has had a severe seizure disorder since the age of 7 months. In his early teens, he lost ambulation and his height and weight fell below the 2nd percentile. He has severe foot dystonia without spasticity. Both patients have a normal head size and no evidence of atrophy on a CT scan of the brain. Both had kyphoscoliosis in their teens. It is difficult to evaluate the incidence of such cases. Little attention being paid to the normal early development, they hide behind vague diagnoses such as cerebral palsy, static encephalopathy, and behavior disorder. Dystonia is often confused with spasticity, the lack of paralysis is not appreciated, apraxia and hand wringing are assumed to be self-stimulatory behaviors.
