Two patients with congenital deafness had spontaneous CSF otorrhea and recurrent bacterial meningitis. A careful workup, including tomograms, is especially important in the treatment of the closed type of CSF otorrhea. At operation of our patients, the leak was found to be at or near the oval window. The stapes was removed, and muscle was packed into the defect. The profuse flow of CSF was believed to be secondary to a wide-open cochlear aqueduct in the first case, and to an abnormal communication between the internal auditory meatus and the vestibule in the second case. These findings were the bases for the recurrent bacterial meningitis.

Bacteremia with known pathogens was documented in 28 acutely ill, febrile outpatients during a 29-month period. All of the children were previously healthy and were initially managed as outpatients. Eight patients presented with no identifiable focus of infection. Twenty patients had either otitis media or pneumonitis. An association between otitis media and bacteremia with H. influenzae type b was noted in 5 patients. Bacterial meningitis occurred subsequently in 7 patients (25%); 1 death occurred in this group. The blood culture, as an outpatient procedure, was helpful in establishing a bacterial etiology in selected children with either high fever (with or without otitis media), febrile seizures, or pneumonia. In addition, the positive blood culture was a vital aid in identifying the young child at risk for meningitis.

Plasma concentrations of arginine vasopressin were determined by radioimmunoassay in 13 normal children, 21 patients with febrile illnesses (not bacterial meningitis), and 17 patients with bacterial meningitis. The mean +/- 1 SD concentrations of AVP in the normal children and patients with various febrile illnesses were 0.7 +/- 0.6 and 1.0 +/- 1.2 muU/ml, respectively. The mean +/- 1 SD concentration of AVP in patients with bacterial meningitis was 3.3 +/- 2.3 muU/ml. The concentrations of AVP in the patients with bacterial meningitis were significantly greater (P less than 0.001) than those noted in the normal children or children with other febrile diseases.

A retrospective study of 547 cases of meningitis was performed. Of these, 236 were bacterial, 304 were viral, and 7 were fungal in etiology. Of 110 survivors of bacterial meningitis over the age of 2 1/2 years, 23 or 21% suffered partial or complete sensorineural hearing loss. The site of auditory injury in cases of partial loss was the cochlea by audiologic criteria. A positive correlation with hearing loss was found for the species of organism, delay before treatment, low CSF sugar, and CSF pleocytosis. Of 7 patients with fungal meningitis, 3 suffered hearing loss with signs of a retrocochlear site. Of 304 cases of aseptic meningitis, none developed a hearing loss. The pathophysiology of hearing loss as a sequela of meningitis and the possible explanations for absence of hearing loss in viral meningitis are discussed.

Postoperative aseptic meningitis may occur as a complication of brain neurosurgery, especially after opening of the fourth ventricle. The picture of bacterial meningitis may be simulated. Main symptoms are persistent spiking fever, meningism and pleocytosis of CSF. The usually long lasting course can be dramatically shortened by early steroid therapy.

The use of antibiotics in viral diseases of childhood is discussed. If bacterial infection is likely, either as superinfection or as part of the differential diagnosis, then antibiotics should be given. The antibiotic of choice for each illness is considered. Respiratory infections are common. The diagnosis and treatment of streptococcal pharyngitis is compared with viral pharyngitis. Penicillin is indicated if the bacterial infection is possible. If there is difficulty in distinguishing between croup and epiglottitis, then chloramphenicol or ampicillin should be given. Otitis media and pneumonia caused by viruses are difficult to differentiate from their bacterial counterparts, and antibiotics are indicated. By contrast, antibiotics are not used in bronchiolitis or asthma. Antibiotics are contraindicated in gastroenteritis even if caused by bacteria. Prolongation of the carrier state or superinfection may then occur. Interpretation of the biochemical and bacteriological findings of the cerebrospinal fluid is important in distinguishing viral meningitis and encephalitis from bacterial meningitis. If bacterial meningitis is possible, then antibiotics should be used. The indications for antibiotics in viral diseases of the skin, eye, joints, heart and parotid are also discussed.

Quantitative lactate determinations were performed on cerebrospinal fluids to assess their value in the rapid diagnosis of bacterial and mycotic meningitis and to evaluate their value in assessing the prognosis in these patients. Cerebrospinal fluid lactate concentrations were elevated in all patients with untreated bacterial or fungal meningitis. Lactate concentrations proved very valuable in following patients with mycotic meningitis and in differentiating aseptic from bacterial meningitis. Elevated cerebrospinal fluid lactate is not specific for meningitis. Lactate is also elevated in situations where there is central nervous system ischemia and necrosis and in patients with brain tumors. Lactate concentration is normal in chronic degenerative brain diseases. Thus, the clinical situation must be taken into account when interpreting the lactate concentrations.

Passage of cephaloridine, cephalothin and cefazolin into cerebrospinal fluid (CSF) was evaluated in Staphylococcus aureus meningitis in rabbits and the following results were obtained. 1. Concentration in CSF (microgram/ml) [CSF/serum ratio (%)] was determined 1/2, 1 and 2 hours after a single intravenous injection of 100 mg/kg of each antibiotic, respectively; cephaloridine-7.5 [8.9], 9.7 [13.8], 9.1 [22.6]; cephalothin-0.42 [3.6], 0.23 [6.4], not detectable [0]; cefazolin-7.5 [11.8], 5.2 [19.3], 2.0 [17.5]. 2. When results with cefazolin after an intravenous injection 100 mg/kg and 200 mg/kg were compared, a definite dose response was noted in blood concentration but not in CSF concentration. 3. A standard error of CSF concentrations of each antibiotic was larger than that of penicillins, and "Unpredictability" of their passage into CSF was considered to be one of the characteristics common to these three drugs in respect of their passage into CSF. 4. There was no significant difference noted in antibiotic passage into CSF between cephaloridine of low protein binding rate and cefazolin of very high binding rate. Cephalothin, of which binding rate was intermediate, showed a remarkably lower passage into CSF. These results indicate that a correlation does not always exist between protein binding rate of the antibiotics and their passage into CSF. 5. Based on the above results, a review of the literature was made on clinical applicability of these three antibiotics in the treatment of bacterial meningitis. Low transport rate of cephalothin into CSF and nephrotoxicity of cephaloridine make them to be unsuitable for bacterial meningitis. Cefazolin is considered to be suitable in the treatment of ampicillin-resistant Escherichia coli meningitis and Gram-positive coccal meningitis in which penicillins are not applicable.

Sudden profound bilateral sensorineural hearing loss is a serious complication of bacterial meningitis. With high dosage Dexamethasone it is possible to halt, and, in some instances, to reverse the progression of the hearing loss. The efficacy of treatment depends upon early diagnosis. Hearing may worsen upon steroid cessation and low dosage oral steroid may be required for several months. The eventual hearing loss may be considerably worse than anticipated. Two cases illustrating differing aspects of the disease are described.

In a retrospective study of 120 children aged 1 month and above with bacterial meningitis confirmed by positive CSF culture, 88.4% were found to be due to three common organisms: H. influenzae, Str. pneumoniae and N. meinigitidis. Gram-negative enteric organisms accounted for 10% of the infections. Despite intensive antibiotic and ancillary therapy, there has been no significant change in case fatality and sequelae over the past decade in this institution. The present study confirms that factors related to the organism and the host are important in determining the outcome of therapy. H. influenzae and Str. pneumoniae infections are associated with statistically significant rise in case fatality rate and neurologic sequelae at the end of therapy. The presence of neurological abnormality at the time of diagnosis significantly increases case fatality rate while delay in diagnosis appears to primarily influence the frequency of neurological sequelae. Protein-energy malnutrition increases the frequency of neurological sequelae and death from bacterial meningitis without significantly influencing the pattern of bacterial aetiology. The finding of enteric Gram-negative meningitis in association with diarrhoeal disease in the present study adds a new dimension to one of the most prevalent health problems in developing countries and needs to be confirmed.
