In forty-five children the hypoxanthine concentration in cerebrospinal fluid (CSF) was measured (fifty-two samples). In newborn infants (nineteen patients) the hypoxanthine levels were higher in patients with clinical conditions associated with hypoxia (idiopathic respiratory distress syndrome, asphyxia, apneic attacks) than in patients without clinical hypoxia (P less than 0.01). In hypoxic patients the hypoxanthine concentration varied between 5 and 28 mu mol/l. In children outside the neonatal period the hypoxanthine concentration in CSF varied considerably in different diseases. High levels were registered in meningitis prior to treatment, febrile convulsions and in lymphoblastic leukaemia, probably reflecting tissue hypoxia and an increased tissue catabolism.

Cerebrospinal fluid amino acid concentrations were measured in 16 pediatric patients with febrile convulsions, in 9 with bacterial meningitis, and in 8 noninfected newborn infants. Most CSF amino acids are present in greater concentration in patients with bacterial meningitis than in those without CNS infection. Newborn infants have elevated CNS amino acid concentrations similar to those found in older patients with bacterial meningitis. The reason for increased amino acid concentration in the meningitis group may be due to alterations in brain metabolism, changes in the kinetics of CSF formation, alterations in the removal of amino acids by active transport mechanisms, or a combination of factors. Delayed maturation of transport mechanisms may explain the high levels found in newborn infants.

Benign febrile convulsions occur early in the course of fever of extracranial origin in children six months to five years old. The first seizure always calls for a spinal tap to exclude meningitis, as well as appropriate studies to exclude other causes of seizure activity. An EEG one week later is indicated but more extensive studies are usually nonproductive. The question of whether to employ long-term phenobarbital therapy has not been resolved.

Simple febrile convulsions occur in otherwise normal children, aged six months to five years, with extracranial infection. Cerebrospinal fluid examination should be done on all children with their first febrile convulsion to rule out an underlying organic disease, especially purulent meningitis. Initial treatment includes antipyretics, tepid sponging and intramuscular phenobarbital. If a seizure recurs, the usual anticonvulsant measures should be carried out and, if prolonged, the patient should receive appropriated doses of diazepam or phenobarbital, intravenously. Patients with suspected epileptic convulsive disorders precipitated by fever, or those with seizures thought to be associated with underlying organic disease, should be hospitalized for further evaluation or treatment or both. Patients with simple febrile convulsions have a benign disorder and can be safely treated as outpatients.

Bromide partition ratio was determined in 32 cases of tuberculous meningitis, 6 pyogenic meningitis, 8 viral meningitis and 9 cases of febrile convulsions. Bromide partition ratio below the critical value of 1.6 was present in 30 out of 32 tuberculous meningitis patients (93.74%) whereas all the control children had a ratio above 1.6. Two children who were on regular chemotherapy showed progressively rising ratio. It is concluded that in doubtful cases with inconclusive CSF picture, a low bromide partition ratio is a strong reason for starting antituberculous treatment without any delay. A very low ratio also suggests poor prognosis.

The authors report 522 infants and young children aged between one month and six years who presented with convulsions and fever as emergencies in Nigeria. 22 had bacterial meningitis, six of whom lacked the usual signs of meningitis. Although features of complex febrile convulsions were significantly associated with bacterial meningitis, it is concluded that, as an aid to the early diagnosis of bacterial meningitis, all preschool children convulsing with fever in developing countries should have a lumbar puncture. This may reduce the contribution of meningitis to chronic neurological disabilities. The necessity for such a policy is illustrated by a case report of a young infant with convulsions and fever caused by meningitis, seen at a general hospital.

During the period April 1985 to November 1986 (18 months), 196 children (of age greater than 1 month) admitted to the Children's Emergency Hospital in Khartoum, Sudan, with clinical suspicion of meningitis/meningoencephalitis were followed up prospectively. Bacterial meningitis was diagnosed by culture, direct microscopy and/or antigen-detecting assays (co-agglutination and enzyme immunoassay) in 44 infants (25 Haemophilus influenzae type b, 8 Neisseria meningitidis, 7 Streptococcus pneumoniae, 3 enterobacteria and one mixed infection), aseptic meningitis in 52, cerebral malaria in 4 and febrile convulsions in 96. The majority of cases of bacterial meningitis were boys and 57% of those in whom H. influenzae was the commonest isolate were less than 1 year old. The presenting signs and symptoms are described as well as the transient and permanent short-term sequelae. The total mortality from bacterial meningitis was 19%, permanent neurological sequelae were seen in 26% of survivors. Prospective follow-up, including audiometry, of 35 children 1-2 months after discharge showed that 11% had hemiplegia and 20% had hearing impairment. The potential impact of vaccination against invasive H. influenzae infections is discussed.

A cohort of 74 children three months to 16 years-old who presented with a first unprovoked seizure were followed for five years to assess the risk of recurrence. Children with febrile convulsions, immediate posttraumatic seizures, meningitis and encephalitis were not included. The risk of recurrence was 68% for a second seizure. 47% of the patients developed an epilepsy. 85% of recurrences occurred within the first 6 months and 100% within 2 1/2 years. A history of epilepsy in a first degree relative, age at first seizure, duration of seizure, initial EEG or neurologic status were not associated with significantly higher risk of recurrence.

Febrile convulsions affect about 1 child in 30. Most of these children have a good outcome with no sequelae and do not require prophylactic medication. Differential diagnosis should include meningitis, epilepsy, hypoglycemia, and encephalopathies and other central nervous system disorders. Children with a high risk for recurrence of seizures may benefit from continuous anticonvulsant prophylaxis.

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.
