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.

Selected clinical and laboratory parameters were studied respectively in patients with meningitis caused by enterococci and viridans streptococci in an academic children's hospital. During a nine-year period (1981-1989), enterococci or viridans streptococci were isolated from the cerobrospinal fluid (CSF) of 48 patients. In nine of these 48 patients, enterococci or viridans streptococci were the causative agents of meningitis. These nine children constituted 2.0% of 450 patients with bacterial meningitis in this period. All nine children suffered from underlying diseases; neurosurgical procedures were performed in six of these patients, of whom four had ventricular drains. A head trauma preceded the development of meningitis in another patient. Drainage of the lacrimal duct was associated with the development of meningitis in another patients. One child concurrently suffered from severe gastroenteritis. CSF leukocyte count and CSF protein levels were moderately elevated, whereas CSF glucose levels were either slightly decreased or within the normal range. Meningitis due to enterococci or viridans streptococci is seen predominantly in children under the age of one year. Predisposing factors, including neurosurgical procedures, head trauma and severe gastroenteritis, are usually present in these patients. The prognosis for recovery is generally good.

A retrospective review of charts for 650 children who had lumbar puncture for suspected meningitis was undertaken to determine the characteristics of patients with and without meningitis, identify other conditions suggesting meningitis, and evaluate the predictive value of signs and symptoms of meningitis. The incidence of positive lumbar punctures increased with patient age. Younger infants did not present with classical features of meningitis. Bulging fontanel, lethargy, and irritability were nonspecific symptoms. Vomiting and headache, although not specific, proved to be more sensitive indicators of meningeal infection. Most patients with meningitis (75%) had at least one sign of meningeal irritation, but so did 25% of patients without meningitis. Brudzinski's sign was not specific. In contrast, nuchal rigidity and Kernig's sign had high predictive value. Up to age five, the diseases most often suggesting meningitis were right-sided pneumonia, gastroenteritis, otitis, tonsillitis, exanthema subitum, and urinary tract infections. Of 171 patients with febrile convulsion, one (0.5%) had bacterial meningitis and four had aseptic meningitis.

It is the policy at the Jordan University Hospital to perform lumbar puncture on children with gastroenteritis who present with one or more of the following: age less than 1 month, convulsions, hypoactivity or marked irritability, and depressed sensorium. Review of the records of 737 children admitted with gastro-enteritis between January 1980 and October 1984 showed that lumbar puncture was performed on 351 (47.6%) children. Acute bacterial meningitis was diagnosed in only three children, two of whom had already received treatment before admission and the third had obvious meningeal signs. These findings do not justify the present policy on lumbar puncture in children with gastroenteritis and it is proposed that the procedure be reserved for children in whom abnormal CNS findings persist after initial correction of fluid and electrolyte balance or with overt signs of meningitis.

In order to study the causes of prolonged and secondary fever in bacterial meningitis, a group of 102 infants and children with proven bacterial meningitis were studied. The causative agent was Haemophilus influenzae in 58% of patients, Streptococcus pneumoniae in 25% and Neisseria meningitidis in 17%. Prolonged fever was observed in 12% of the patients. The established causes include, in order of frequency, subdural effusion, drug fever, otitis media, gastroenteritis and urinary tract infection. Secondary fever was noted in 18% of the patients. The causes, in order of frequency, were urinary tract infection, subdural effusion, otitis media, phlebitis, pneumonia and drug fever. Neither relapse of the meningitis nor inadequate response to antibiotic therapy was the cause for prolonged or secondary fever. Neurological sequalae were observed in 21 patients. There was no correlation between prolonged or secondary fever and neurological sequalae. We conclude that prolonged and secondary fever in patients with treated bacterial meningitis is rarely caused by the primary infection.

Four hundred thirty-four febrile infants two months of age or younger were evaluated in the emergency departments of five major teaching hospitals over a one-year period. A culture-proven bacterial infection was present in 3.5% of the infants; bacteremia was detected in 3.3%. Bacterial meningitis was present in 2.4%, and aseptic meningitis was noted in 13.4%. Twenty-one percent had clinically apparent serious disease including pneumonia, otitis media, and gastroenteritis with dehydration. Six variables (age less than 1 month, lethargy, no contact with an ill individual, breast-feeding, total polymorphonuclear greater than or equal to 10,000/mm3 and band count greater than or equal to 500/mm3) were correlated with bacterial infection by step-wise discriminant analysis. However, these findings were neither sensitive nor specific enough to be clinically useful. Management varied, and 62% of the infants were hospitalized. Fifty-four percent, some of whom were managed as outpatients, received antibiotics. Febrile infants two months of age or younger require a comprehensive emergency department assessment, including appropriate laboratory studies (CBC, differential, urinalysis and culture, lumbar puncture, and blood culture), since 3.5% have bacterial infection that may be life-threatening. Hospitalization is warranted if the infant appears ill, laboratory studies indicate serious infection, or follow-up care is uncertain.

Blood leukocytes from 37 patients with acute bacterial infections, and cerebrospinal fluid (CSF) granulocytes from 12 patients with bacterial meningitis, were examined for the distribution of membrane receptors (R) for (1) untreated sheep erythrocytes (E), (2) the Fc portion of IgG (Fc gamma), and (3) complement component C3b. We found a decreased percentage of granulocytes bearing Fc gamma-R in the CSF from patients with meningitis, and in blood from patients with respiratory tract infections. This group also had a decreased percentage of C3b-R bearing granulocytes on admission, whereas meningitis patients had lower levels of C3b-R and Fc gamma-R bearing granulocytes in the 2nd and 3rd week and even later. Several patients with meningitis and gastroenteritis had granulocytes bearing the E-R, previously considered specific for T lymphocytes. Such cells were also found in the CSF. Meningitis and respiratory tract infections were associated with a decreased percentage of 'active' T lymphocytes. The total percentage of T lymphocytes was also decreased in meningitis. Conversely the proportion of Fc gamma-R bearing lymphocytes (consisting mostly of B lymphocytes) was increased in most infections. During the first 3 weeks of bacterial meningitis, the percentages of Fc gamma- and C3b-R bearing granulocytes, and of Fc gamma-R bearing lymphocytes, gradually decreased, while the T lymphocyte percentage increased from the initial low values.

In recent years, Aeromonas species has been reported to cause extraintestinal infections with a growing frequency. Meningitis due to Aeromonas species is, however, a rare entity. We report a case of aeromonas meningitis in a 54-year-old man with a history of chronic alcoholic liver disease who, after an episode of gastroenteritis, developed an acute clinical picture characteristic of meningitis with septic shock and ecthyma gangrenosum. Aeromonas veronii (biogroup sobria) was isolated from cultures of blood as well as from cultures of stool, peritoneal fluid, skin lesion, and CSF specimens (obtained by lumbar puncture). Our review of seven additional cases of aeromonas meningitis in the world literature revealed that this condition is generally secondary to metastatic dissemination from primary bacteremia. Aeromonas meningitis, which may or may not be preceded by gastroenteritis, presents clinically as bacterial meningitis, although the presence of skin lesions may increase suspicion of the diagnosis. Third-generation cephalosporins are probably the therapy of choice for patients with aeromonas meningitis.

Interleukin-8 (IL-8) elaborated by monocytes and endothelial cells is a cytokine which is responsible for adhesion of leucocytes to vascular endothelium and migration of neutrophils into the cerebrospinal fluid (CSF) from the intravascular space. The inflammation in meningitis is elicited by the cytokine release from leucocytes which encounter micro-organisms in the arachnoid or subarachnoid space. In bacterial meningitis, tumour necrosis factor (TNF), IL-1 and IL-6 are produced vigorously, and initiate and augment the inflammation in the central nervous system. In this study, utilizing a quantitative immunometric sandwich enzyme immunoassay, the concentration of IL-8 was investigated in the CSF of patients with bacterial meningitis, patients with aseptic meningitis, and patients with gastroenteritis who served as controls. The IL-8 concentration was markedly higher in the CSF of patients with bacterial meningitis (224 +/- 2.57 pg/ml; mean +/- SD) than in the CSF of patients with aseptic meningitis (less than 30 pg/ml). The IL-8 level in the CSF of patients with aseptic meningitis did not differ from that in the CSF of the patients with gastroenteritis (less than 30 pg/ml). The augmented production of IL-8 in CSF may account for the inflammation in bacterial meningitis being more severe than that in aseptic meningitis.

The purpose of this study was to determine the applicability of two accepted outpatient management protocols for the febrile infant 1-2 months of age (Boston and Philadelphia protocols) in febrile infants 1-28 days of age. We retrospectively reviewed charts of patients 1-28 days of age with a temperature greater than or equal to 38.0 degrees C. Criteria from each of the above-cited management protocols were applied to the patients to determine their applicability in screening for serious bacterial infection (SBI). An SBI was defined as bacterial growth in cultures from blood, urine, cerebrospinal fluid (CSF), stool, or any aspirated fluid. Overall, 372 febrile infants were included in the study. Ages ranged from 1 to 28 days of age. The mean age was 15 days. SBI occurred in 45 patients (12%). The mean age of the patients with an SBI was 13 days. Thirty-two infants (8.6%) had a urinary tract infection; 12 (3.2%), bacteremia; five (1.3%), bacterial meningitis; three (0.8%), cellulitis; one (0.3%), septic arthritis; one (0.3%), bacterial gastroenteritis; and one (0.3%), pneumonia. Ten infants had more than one SBI. Of 372 patients, 231 (62%) met the Boston's laboratory low-risk criteria; eight (3.5%) would have been sent home with an SBI with these criteria. Philadelphia's laboratory low-risk criteria would have been met by 186 patients (50%); six (3.2%) would have been sent home with an SBI with these criteria. The negative predictive value of both the Boston and Philadelphia protocols for excluding an SBI was 97%. We conclude that current management protocols for febrile infants 1-2 months of age when applied to febrile infants 1 to 28 days of age would allow 3% of febrile infants less than 28 days of age to be sent home with an SBI. Current guidelines recommending admitting all febrile infants less than 28 days of age should be followed until the outcome of those 3% of febrile infants with an SBI treated as outpatients can be determined.
