Lysozyme is absent from normal cerebrospinal fluid (C.S.F.) and in C.S.F. from children with viral meningitis. Appreciable amounts of lysozyme were noted in C.S.F. from children with bacterial meningitis (0.23 +/- 0.14 mg/100 ml) and cerebral convulsions (0-0.82 mg/100 ml). The C.S.F.-lysozyme content is a sensitive indicator for bacterial meningitis and important in the differential diagnosis between viral and bacterial meningitis. The beta2-microglobulin content of C.S.F. in healthy children was 0.11 +/- 0.05 mg/100 ml; in children with viral meningitis 0.20 +/- 0.06 mg/100 ml and in children with bacterial meningitis 0.44 +/- 0.17 mg/100 ml. Children with cerebral convulsions had also a rise in C.S.F. beta2-microglobulin.

Four patients with bacterial meningitis are reported. On initial examination 1 patient had a slightly abnormal cerebrospinal fluid (CSF), and in the other 3 patients the CSF was completely normal. An obviously purulent CSF was obtained when lumbar puncture was repeated 14-48 hours later. All 4 patients presented initially with pyrexia, and either neck stiffness or convulsions. In 3 of the 4 patients a cause for pyrexia was found on initial examination but lumbar punctures were done for neck stiffness or convulsions to exclude meningitis. The problems and the need to repeat a lumbar puncture, as well as the importance of blood cultures in a patient with suspected meningitis, are discussed. The fact that a normal specimen of CSF does not exclude meningitis is stressed.

Review of 208 patients with bacterial meningitis, admitted from march 1, 1971 to march 1, 1976. Incidence peak was found in Winter (december to march). Etiologically N. meningitiditis, 39, 9%, was the mainly predominate germ. In 49% of the patients C.S.F. cultures were negative, significantly influenced by the previous treatment with antibiotics (P less than 0.001). Cure was obtained in 86.5% Convulsions, 12%, were the most frequent complication, followed by subdural effussion, 3.8%, and arthritis, 2.4%. Twenty patients died, 9.6%; fifteen of them with endotoxic shock. Definitive sequelae was present in the 3.8%, mainly hidrocephaly. A comparative study with other series in Spain is performed.

A total of 522 children, aged 1 month to 6 years, who presented with convulsions and fever of acute onset at the Children's Emergency Room of the University of Benin Teaching Hospital over a 1-year period, were prospectively evaluated. Bacterial meningitis was diagnosed in 22 (4.2%) on bacteriological and/or biochemical evidence. The causative organisms were cultured from the CSF in 13 (Neisseria meningitidis = 7, Streptococcus pneumoniae = 5 and Haemophilus influenzae = 1) and identified by Gram stain only in three (Gram-positive diplococci = 2 and Gram-negative diplococci = 1). No organisms were identified in the CSF of six of the children with meningitis. The prevalence of meningitis declined sharply after 6 months of age. Six of the children with bacterial meningitis lacked classical meningeal signs but had other indications for lumbar puncture. The following were significantly associated with meningitis: age under 6 months; focal or multiple seizures; absence of a past or family history of seizures; unrousable coma; and an extracranial focus of infection. It is concluded that bacterial meningitis occurs in a good proportion of children, even beyond infancy, with convulsions associated with fever of acute onset, and that decision on the need for lumbar puncture should be guided by clinical features such as age and the presence of complex febrile seizures.

The diagnosis of bacterial meningitis can be difficult nowadays when antibiotics are freely used in infants and children with fever due to infection, so that a positive smear or culture may be difficult to achieve. In areas where sophisticated methods of diagnosis may be hard to come by, the simple procedure of simultaneously estimating the blood and cerebrospinal fluid (CSF) glucose levels may be helpful in distinguishing bacterial meningitis from viral meningitis. 74 proven cases of bacterial meningitis and aseptic meningitis were investigated prior to treatment. There were 36 cases of bacterial meningitis and 38 cases of aseptic meningitis. The CSF glucose/plasma glucose ratio was calculated for each patient. The cases were divided into two groups; Group A with CSF glucose/plasma glucose ratio of (0.38-2.0) and Group B with CSF glucose/plasma glucose ratio of (0.1-0.35). In Group A, two out of 59 cases died while in Group B, nine out of 15 died (p < 0.01). 44 out of 59 in Group A recovered fully while only two out of 15 in Group B were cured (p < 0.01). It was also found that 54.2% in Group A were admitted in deep coma compared with 86.7% in Group B (p < 0.05) and 25.4% in Group A were admitted with seizures while 66.7% in Group B had convulsion (p < 0.01). Hence, a low CSF glucose/plasma glucose ratio was associated with a poor outcome. The mechanisms responsible for these findings are discussed especially with reference to the blood-brain barrier (BBB).(ABSTRACT TRUNCATED AT 250 WORDS)

The treatment of children with bacterial meningitis includes many aspects, such as fluid and antibacterial therapy, treatment of convulsions, and prophylactic use of dexamethasone. This report focuses in particular on the prophylactic use of dexamethasone together with cefalosporines in order to reduce inflammation and neurological sequelae in this disease. Probably this approach is now justified in the treatment of meningitis caused by Haemophilus influenzae. Modern principles for fluid therapy and treatment of increased intracranial pressure are also discussed.

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.

In most developing countries, bacterial meningitis (BM) is associated with a high case-fatality rate. The search for a simple, convenient, and inexpensive antibiotic treatment remains a priority. In this study, a non-blinded, multicentre, randomised clinical trial of 528 cases of BM was done in two hospitals in Mali and Niger, between March, 1989, and May, 1990, to see whether a double injection of long-acting chloramphenicol (on admission to hospital and 48 h later) is as effective as a course of intravenous ampicillin (8 days, 4 times a day). The cumulative case-fatality rate on day 4 (principal end-point) among the chloramphenicol (254 patients) and ampicillin (274) groups were, respectively, 28% and 24.5% (relative risk 1.14, 95% confidence interval 0.86-1.52). No outbreak occurred during the study period. The hospital case-fatality rate was 33.1%. Main risk factors for death were associated with clinical condition on admission--ie, altered consciousness, convulsions, or dehydration. The case-fatality rates were 13% (21/161) for Neisseria meningitidis, 36.1% (48/133) for Haemophilus influenzae, and 67% (77/115) for Streptococcus pneumoniae. In a multiple logistic regression model, controlling for the differential distribution of potential risk factors (including bacterial species), there was no difference between treatment groups. Our findings suggest that long-acting chloramphenicol is a useful first-line presumptive treatment for BM in high-incidence countries.

Six children aged 13 days to nine years with herpes simplex encephalitis (HSE) are presented. Institution of appropriate antiviral treatment was later than six days in three cases; original diagnosis in these cases were post-traumatic epilepsy, bacterial meningitis and febrile convulsion. Initially pyrexia was absent in two cases and cranial CT was normal in two cases. Encephalitic changes were observed on the EEGs of five children. Diagnosis was confirmed by paired serological titres, brain biopsy, vesicle culture and CSF titres. The outcome for all six children was poor. HSE should always be considered in children presenting with focal seizures, even when apyrexial and with normal CT findings. In such situations, saving CSF for antibody titres or antigen identification should be routine practice. Treatment with acyclovir is justified before precise virological diagnosis has been established.

Spinal epidural abscesses (SEA) are uncommon in children. This paper reported a two-year-old boy who was noted to have neck stiffness, with local tenderness posteriorly. Bacterial meningitis was suspected initially in terms of the finding of the cerebral spinal fluid; antibiotics were prescribed. Three days later another spinal tap was performed because of persistent high fever and irritability. A pus-like material drained out as the needle punctured into the spinal region. A magnetic resonance image (MRI) scan of the spine revealed a SEA, with extensive involvement from the second cervical spine to the lumbosacral spine region. Culture of the pus, as well as the blood and CSF, were positive for Staphylococcus aureus. Because of extensive involvement of the spinal epidural space, the patient was again given antibiotics: Prostaphllin and Amikin intravenously for six weeks instead of laminectomy. Then the oral antibiotic (Keflex) was given to the patient for another three months after the boy was discharged from the hospital. A review of the literature shows the incidence of SEA to be increasing and the bacterial spectra to be broadening because of increasing use of immunosuppressing drugs or antibiotics, and the increase in numbers of immunecompromised patient. The clinical symptoms and signs of the SEA were non-specific, but SEA can be early diagnosed by computurized tomography (CT) scan or MRI scan with caution. The literature suggests that, if the patient's condition fits the criteria for non-surgical treatment, antibiotic therapy is the first choice for preventing the complication of spinal deformity, especially in children.
