Following acute meningitis associated with severe convulsions in childhood, two patients had chronic, drug-resistant, temporal lobe epilepsy. This disorder was preceded by an entirely natural development, in one case extending for nine years and in the other case for eight years. Each patient was treated with right anterior temporal lobectomy. Classic mesial temporal sclerosis (Ammon's horn sclerosis) was found in both patients. Relief of the epilepsy was associated with remission of the concomitant social and psychiatric handicaps. At least ten years of follow-up are required in the evaluation of the treatment of early brain infections. Chronic focal epilepsy after childhood meningitis with febrile convulsions merits neurosurgical consideration.

Previous studies have suggested that levels of cerebrospinal fluid (CSF) gamma-aminobutyric acid (GABA) may be decreased in children with febrile seizures. We used gas chromatography and mass spectrometry to measure CSF GABA levels in 14 children with febrile seizures. The results were compared with the GABA levels in six children with first-time afebrile seizures, three with recurrent febrile seizures, and 13 controls (febrile children undergoing lumbar puncture to rule out meningitis). Children with central nervous system infections or known neurologic disease were excluded. The CSF GABA levels in children with febrile seizures were not significantly different from those in controls and children with afebrile or recurrent febrile seizures. In the control group, CSF GABA levels correlated with increasing age. There was no correlation with severity of febrile response in any group. The results indicated that the CSF GABA level may not be abnormal in patients with first-time febrile convulsions.

In 14 children with epilepsy, 51 with febrile convulsions and 22 with meningitis gamma-aminobutyric acid (GABA) concentrations in lumbar CSF were determined. While the mean for CSF GABA concentrations for all epileptic children was unchanged [144 (range: 73-285) pmol/ml; controls: 148 (range: 90-243) pmol/ml] extraordinarily high GABA levels were found in the CSF of two children on valproate (525 and 557 pmol/ml) and remarkably low GABA concentrations in hitherto untreated epileptic children [109 (range: 67-176) pmol/ml]. Children with febrile convulsions [103 (range: 63-170) pmol/ml] and acute meningitis [105 (range: 65-171) pmol/ml] had significantly decreased CSF GABA concentrations (P less than 0.001 and P less than 0.02 compared with controls). The data indicate that valproate intake increases dramatically the GABA concentrations in the CSF of epileptic children. Furthermore, the study supports the concept that low GABAergic activity within the CNS may be one cause for an increased seizure frequency.

Over two years 29 children had bacteraemia due to Streptococcus pneumoniae at this hospital. In 15 previously healthy children the site of infection could not be identified, and in most of them, bacteraemia was not suspected clinically. All 15 had high total white cell (greater than or equal to 17 x 10(9)/1) and neutrophil (greater than or equal to 11 x 10(9)/1) counts. Twelve children were under 4 years of age, and of these, 10 had been admitted because of a simple febrile convulsion and one had a prolonged febrile convulsion. Occult pneumococcal bacteraemia has been reported in the USA for more than 10 years, but no series has been reported from the United Kingdom. Occult pneumococcal bacteraemia may be an important cause of febrile convulsions. Persisting bacteraemia and the development of focal infections, including pneumococcal meningitis, have been reported. Meningitis did not occur after occult bacteraemia in our patients. Studies to date have been retrospective, and thus the true incidence of the complications and the best treatment are not clear. A prospective study of children with febrile convulsions could provide answers.

Cerebrospinal fluid prostaglandin F2 alpha (CSF PGF2 alpha) levels were measured by radioimmunoassay in children as follows: Febrile convulsions (31 cases), epilepsies (32 cases), meningitides (31 cases) and non-neurological diseases (20 cases), totaling 114 cases. A 4.5-fold increase in CSF PGF2 alpha levels was seen in simple febrile convulsion, and a 2.5-fold increase in those with complex febrile convulsion as compared to those with non-neurological diseases. On the other hand, no increase in CSF PGF2 alpha levels was seen in children with epilepsy. When the body temperature was normal, the mean CSF PGF2 alpha levels showed no relation with age. When the body temperature was between 37.5 degrees C and 40 degrees C, the CSF PGF2 alpha levels in infants were higher than those in older children. The CSF PGF2 alpha levels in children with meningitis were high. The mean CSF PGF2 alpha levels in bacterial meningitis were not statistically (p greater than 0.05) different from those in viral meningitis. The CSF PGF2 alpha levels in meningitis were high on admission and gradually decreased with therapy. The results of our studies indicate that PGF2 alpha of the central nervous system markedly increased in infants and children with febrile convulsions or meningitis but not in those with epilepsy.

Analysis of cerebrospinal fluid lactic acid levels in 62 patients suspected of having meningitis was performed. Lactic acid was measured enzymatically using lactic acid dehydrogenase with the liberation of NADH. In a control (no meningitis) group, 46 children had a mean cerebrospinal fluid lactic acid level of 14.7 +/- 2.2 mg/dl; 3 with febrile seizure had a mean lactic acid level of 33.5 +/- 0.98 mg/dl. In 9 cases of bacterial meningitis, the mean lactic acid level was 54.8 +/- 16.8 mg/dl. In 3 patients of aseptic meningitis, the mean lactic acid level was 34.5 +/- 1.0 mg/dl. Serial lactate determination was done in three patients and they were well correlated with the clinical response and other cerebrospinal fluid findings. These data suggest that the determination of cerebrospinal fluid lactic acid may be of diagnostic value in differentiating between bacterial and aseptic meningitis.

A prospective epidemiological study of the incidence of simple febrile convulsions (FC) was performed in a northern Swedish county. The yearly incidence was 700/100 000. The children with FC were re-examined three years later. The pre- and perinatal complications were significantly more common in the group of children with FC than in a randomly collected group of controls. The value of an extensive investigation program is discussed. Between six months and five years of age the children with FC can be separated from those with other cerebral diseases causing epileptic seizures by recording a thorough history followed by a somatic and neurological physical examination and a determination of acute blood glucose. In children less than six months of age and in children in which meningitis or encephalitis cannot be ruled out, a lumbar puncture and a blood culture should be performed. If the onset of the convulsion has been after five years of age, if the seizures are partial or have a duration of more than 30 minutes, or if signs of cerebral disease are found, the examination should be supplemented with EEG and relevant investigations. There is no need for an extensive routine program of investigations in the care of children with FC.

Childhood hyperpyrexia is associated with serious infections particularly bronchopneumonia, infective diarrhoea, meningitis, measles, urinary tract infections, otitis media, septicemia and sickle cell crisis Hyperpyrexia was found most in children aged 6-12 months followed by children aged 12-18 months. Hyperpyrexia occurred least in children aged 2-6 months. Febrile convulsion was associated with 38% of the cases. Malaria was a cause of convulsion in 27% of children with fever. This appears to contrast earlier reports by Lennox (1953) and Familusi (1971). The study confirms the rarity of hyperpyrexia in children aged 3 months and under. Deaths recorded were in children brought at the late stages of their ill health. Intensive health education is recommended to obviate unnecessary death of children through ignorance and poor knowledge of simple first aid measures.

Zinc modulates the activity of glutamic acid decarboxylase, the rate limiting enzyme in the synthesis of gamma-aminobutyric acid (GABA), which is a major inhibitory neurotransmitter. Low cerebrospinal fluid GABA values have been reported in association with several seizure disorders, including febrile convulsions. It is also known that fever and/or infections may cause a reduction in serum zinc concentrations. In this study the hypothesis that febrile convulsions are related to low cerebrospinal fluid zinc was tested. Cerebrospinal fluid zinc concentrations were measured in 66 febrile children: 32 with febrile convulsions, 18 with fever but without convulsions, and 16 with aseptic (viral) meningitis. There was no statistically significant difference in the cerebrospinal fluid zinc between the three groups of children, and the mean concentration was 26.2 micrograms/l. No significant relationship was found between either age, gender, maximal temperature, type of infection, or time of performance of the lumbar puncture and cerebrospinal fluid zinc concentration. These results do not support the hypothesis that febrile convulsions are related to reduced cerebrospinal fluid zinc concentrations.

Cerebrospinal fluid (CSF) was analysed to determine a lumbar puncture (LP) yield for meningitis in 95 children who presented with their first febrile convulsions between July 1993 and June 1994. There were 52 males and 43 females aged six months to six years with a mean age of 21.9 +/- 13.0 months at presentation. 87(91.6%) had simple febrile convulsions (SFC) while the remaining 8(8.4%) had complex febrile convulsions (CFC). The majority of the subjects presented with a sudden onset of convulsions that were preceded by a day or two history of fever, coryza, cough and respiratory distress while others had their convulsions preceded by fever and passage of bloody stools. The LP yield for meningitis in this series was 6.3%. The CSF analysis revealed six cases of meningitis comprising an eight month old infant with Haemophilus influenzae type B (HIB) meningitis, two partially treated pyogenic meningitis and three aseptic meningitis. All of them had presented with febrile convulsions without signs of meningeal irritation. Excluding aseptic meningitis from this series, a 3.1% LP yield for pyogenic meningitis is significant enough to recommend continued performance of LP in children with first febrile convulsions, especially if under the age of eighteen months.
