The study of CSF fistulae, and especially those involving otolaryngological anomalies, must be based on the search for the causative problem of recurrent meningitis. Congenital malformations, post-traumatic and post-operative situations or even diseases involving the cranial bones are basic causes that should be studied. Currently, cranial trauma is the most usual cause of CSF fistulae, with the possibility of recurrent bacterial meningitis.

Cerebrospinal fluid rhinorrhea is an uncommon but dangerous disease. Many lethal complications, such as bacterial meningitis and pneumoencephalus, may be the result of cerebrospinal fluid rhinorrhea. Otolaryngologist, neurosurgeons and radiologists must know how to diagnose, how to localize the site of leakage and how to choose the best method of treatment. A case of cerebrospinal fluid rhinorrhea and meningitis due to improper sinus surgery is presented. Satisfactory result, such as avoidance of unnecessary brain tissue damage, can be obtained by extracranial endonasal repairing of the fistula with a composite septal flap.

We present 4 cases of tuberculous meningitis with atypical clinical features and CSF findings. Two patients had initially normal CSF examination, one developed internuclear ophthalmoplegia, while the other had deterioration of consciousness. The third patient presented with paranoid psychosis, and the fourth had a picture mimicking acute bacterial meningitis and he developed right hemianopia due to a tuberculoma detected by MRI. All recovered completely with anti-tuberculous treatment.

During the four years period from 1988 to 1991, 50 pediatric patients were diagnosed to have bacterial meningitis, out of a total number of 9057 pediatric admissions at Qatif Central Hospital, Qatif, Saudi Arabia, and 82% were less than two years of age. The causative organisms were isolated in 27 (54%) patients. The bacteria grown included Haemophilus influenzae type B in 8 patients (29.6%), Neisseria meningitidis in 8 patients (29.6%), Streptococcus pneumonia in 6 (22%) patients, and other bacteria in 5 patients (18.5%). Cerebro spinal fluid cultures from twenty three patients (46%) showed no organisms, however their clinical and C.S.F. findings were compatible with bacterial meningitis. One case of H. influenzae type B was resistant to ampicillin. Six patients died with an over all mortality of 12%, and 10 patients (20%) developed some kind of C.N.S. sequelae. Partially treated meningitis formed a large percentage of our sample.

Subdural empyema is a known yet infrequent complication of bacterial meningitis. Subdural effusions occur frequently with meningitis in children and usually resolve spontaneously or with subdural taps. Subdural empyema should be suspected when a patient fails to respond to antibiotic therapy or worsens neurologically. Computed tomography (CT) scans with contrast often show enhancement of subdural collections when an empyema exists. However, this is not true all of the time. We present a case of subdural empyema complicating bacterial meningitis in a 4 month old in which CT enhancement was not present yet magnetic resonance imaging (MRI) scans with gadolinium demonstrated intense enhancement. For comparison, we present a second case of a child with sterile subdural effusions due to meningitis that demonstrates an absence of contrast enhancement on MRI studies. MRI scans with contrast may offer a more sensitive means of making an early diagnosis of subdural empyema.

Mortality from meningitis caused by Haemophilus influenzae type b (Hib), a disease that affects mainly infants and young children, can reach 5% in industrialised countries and ten times that in non-industrialised countries. To determine the efficacy of vaccination against Hib, we carried out a retrospective survey of the incidence of Hib meningitis over five decades in the Greater Helsinki area of Finland, where all children with bacterial meningitis are treated in one of three centres. Except for a meningococcal epidemic in the early 1970s, Hib was the leading cause of childhood bacterial meningitis until the Hib conjugate vaccines changed the picture profoundly. In 1986-87 the polysaccharide-diphtheria toxoid conjugate (PRP-D) was given experimentally to 50% of infants. In 1988-89 all infants were vaccinated, 50% with PRP-D, 50% with another conjugate vaccine, the oligosaccharide-CRM197 protein conjugate (HbOC). Since 1990 a third conjugate vaccine, the polysaccharide-tetanus toxoid (PRP-T), has been administered routinely to all infants. The vaccines were administered at age 3-6 months, with a booster dose at 14-18 months. In the first 5 years of the Hib vaccination programme the number of cases of Hib meningitis in children aged 0-4 years fell sharply, from 30 in 1986 (the first year of the programme) to none in 1991. The decline contrasts sharply with the rising trend up to the mid 1980s. Vaccination seems to be the only explanation for the observed change in the epidemiology of Hib meningitis.

Neonatal bacterial meningitis has a relatively low incidence in developed countries, but continues to cause morbidity and mortality despite advances in antimicrobial therapy. Bacterial pathogens commonly associated with neonatal meningitis include Group B streptococci, Escherichia coli K1 and other coliforms, Listeria monocytogenes and staphylococci. As it can be difficult to differentiate meningitis from septicaemia in neonates, empirical antibiotic therapy should be effective for both. Selection of an empirical antibiotic regimen should be based on: (a) bacterial prevalence and susceptibility; (b) drug characteristics; (c) postnatal age at the onset of disease; and (d) patient-specific factors. A penicillin in combination with an aminoglycoside or cefotaxime is commonly used in empirical therapies. The increased risk of staphylococcal infection in older neonates requires consideration of an antistaphylococcal antibiotic in the empirical therapy regimen. Once a causative organism has been identified, antimicrobial therapy should be directed towards that pathogen. Duration of therapy remains empirical, but should be at least 7 days for documented bacterial meningitis. Viral meningitis continues to have a high mortality despite the availability of antiviral agents. Adjunctive therapies may further reduce the morbidity and mortality of meningitis. While most of these therapeutic options have not been investigated in neonates, they may prove to be of benefit in the future. Anti-inflammatory agents, such as glucocorticoids, nonsteroidal anti-inflammatory agents and immunoglobulin, may modulate the inflammatory response of a meningeal infection. Other possible therapies in neonatal meningitis include cerebral blood flow modulators and disease prevention with maternal vaccines and perinatal antibiotics. Practical aspects of drug therapy such as route of administration and serum drug concentration monitoring can improve both drug therapy and patient outcome. While antibiotics have greatly improved the treatment outcome of neonatal meningitis, it is clear that additional intervention will be required to increase cure rates and reduce sequelae.

The diagnosis of bacterial meningitis depends on a lumbar puncture (LP). Sometimes, antibiotics are administered before a LP that is delayed owing to prior need for computerized tomography (CT) scan, technical problems, inability to obtain consent, or an unstable patient. We examined the accuracy of blood culture, cerebrospinal fluid (CSF) Gram's stain, and antigen detection by latex for organism identification of meningitis. All patients admitted to the Children's Hospital of Buffalo between January 1, 1984 and December 31, 1989 and having a CSF culture diagnosis of bacterial meningitis had their charts retrospectively reviewed. Patients excluded from the study were those with neural tube defects or CSF catheters, those admitted directly to the Intensive Care Nursery (ICN), those whose positive CSF cultures were determined to be a contaminant, those whose medical records were not found, or those older than 16 years. We analyzed a total of 178 patients with positive CSF cultures and the confirmed diagnosis of bacterial meningitis. Of 169 patients who had a blood culture performed, 86% had the organism responsible for meningitis recovered by this test, with the highest yield of 91% occurring in the 2.5-month to 24-month age group. Blood culture identified the bacteria in 94% of those patients with Haemophilus influenzae meningitis, and this yield increased to 100% when patients who had been pretreated with antibiotics were excluded. The combination of blood culture, CSF Gram's stain, and/or latex agglutination identified the causative bacteria in 92% of patients with meningitis. Blood culture, CSF Gram's stain, and latex agglutination are useful in identifying the organism causing pediatric meningitis.(ABSTRACT TRUNCATED AT 250 WORDS)

A prospective study of acute bacterial meningitis in infants and children in Kumasi, Ghana identified 69 cases by culture or antigen detection. Of these, 50.7% (n = 35) were S. pneumoniae, 34.8% (n = 24) N. meningitidis and 14.5% (n = 10) H. influenzae. The mortality for each pathogen was 36.4%, 17.4% and 30%, respectively, showing no significant difference. In pneumococcal meningitis, the most significant clinical factor associated with an increased mortality rate or subsequent neurological sequelae was a lowered level of consciousness at admission (chi 2 = 8.66, d.f. = 1, p = 0.003). Antibiotic susceptibilities were determined in the 40 positive isolates. Six cases of N. meningitidis and two of S. pneumoniae were penicillin-resistant, and there was a single case of chloramphenicol-resistant S. pneumoniae.

Brain abscesses are rare in infants and their clinical presentation is specific for this age group. Seven cases of brain abscess in infants aged 2-11 months are reported. The underlying cause was meningitis in four, sepsis in two, and unknown in one. Gram-negative organisms were cultured in 6 patients. The abscess size was 5 cm or more in five cases; in four there were multiple lesions. Two abscesses were aspirated and irrigated; four particularly large lesions were drained and repeatedly aspirated and irrigated. One craniotomy was done. There were two deaths, one in the postoperative period and the other 6 months after discharge. Follow-up information is available for four children, showing a good result in only one of them. Formation of an abscess should be diagnosed early, and close ultrasound monitoring or CT scanning in infants with bacterial meningitis and sepsis is essential. The prognosis in cases in which large/multiple abscesses develop is poor.
