A total of 82 patients involving 83 episodes of proven or presumed bacterial infection were treated with sulbactam/ampicillin. These included 36 cases of soft tissue infection or abscess, four cases of joint or bone infection, 20 cases of respiratory tract infection (17 cases of pneumonia, two of otitis media, and one of tonsillitis), 15 urinary tract infections, three cases of enterocolitis, one case of infective endocarditis, two cases of septicemia, and two of peritonitis. The causative pathogen was isolated in 48 cases (49 infections). These pathogens included Staphylococcus aureus 13 cases, Staphylococcus epidermidis one, Streptococcus pyogenes two, Streptococcus pneumoniae two, Viridans group streptococcus two, peptostreptococcus one, Haemophilus influenzae one, Escherichia coli 12, Enterobacter cloacae three, Proteus mirabilis one, Acinetobacter calcoaceticus one, Salmonella spp. two, Shigella sonnei one, Bacteroides fragilis one, and polymicrobial infections of various combinations in five cases. No bacterial pathogens were isolated in 34 infections, 14 cases of pneumonia and 15 soft tissue infections. Sulbactam/ampicillin was given by intravenous bolus in a dosage range of 75-450 mg/kg/day in four divided doses for variable periods of time depending on the type and severity of the infection. Of a total of 83 episodes of infections, 80 (96.4%) cases were either cured or improved. Bacteriologic eradication also occurred in 46 (93.9%) of 49 infections. Side effects were diarrhea in two patients, acute hemolytic anemia in one patient, and transient elevations in SGOT and leukopenia in one patient. Side effects disappeared upon completion of treatment. Sulbactam/ampicillin is a safe and effective antibiotic for the treatment of common pediatric infections.

The bacterial flora of the nose and nasopharynx was studied in 86 healthy young men. Common pathogens (Haemophilus influenzae and Streptococcus pneumoniae) were isolated from only 6% of all 172 nasal cavities. The same pathogens were isolated from 27% of 86 nasopharyngeal samples. H. influenzae dominated over S. pneumoniae both in the nose and the nasopharynx. No culture either from the nose or nasopharynx grew Streptococcus pyogenes. Potentially pathogenic bacteria, non-group-A hemolytic streptococci and various groups of Neisseria meningitidis were isolated from the nasopharynx in 20% of the subjects. According to the present study healthy adults do not carry group-A hemolytic streptococci in the nose and seldom if ever in the pharynx. Thus, isolation of S. pyogenes by bacterial culture is suggestive of a bacterial infection by this agent at these sites. Isolation of hemolytic streptococci other than group A from the pharynx does not necessarily indicate bacterial infection, and the same holds true for H. influenzae and S. pneumoniae.

In acute maxillary sinusitis, purulence could best be assessed from sinus washings, but evaluation based on aspirates was also reliable, provided that the amount of secretion was adequate. Injection-aspirates were of negligible diagnostic value in this respect. Sinus washings and aspirates which were clinically defined as purulent were almost invariably indicative of bacterial infection. The bacterial etiology was most accurately obtained by sinus aspiration. Only 14.5% of cultured specimens were negative for pathogenic bacteria. In maxillary sinusitis, judged to be non-purulent, 52.5% of cultures grew a pathogen. The most common pathogen was Haemophilus influenzae, which accounted for 90% of these isolations. There was a clear correlation between occurrence of many PMNs and pathogen positive culture in non-purulent cases. Thus, antimicrobial therapy which is effective against Haemophilus influenzae seems indicated in most cases of non-purulent maxillary sinusitis.

Clinical and bacterial findings were prospectively studied in 90 children hospitalized because of middle or lower respiratory tract infection caused by respiratory syncytial virus (RSV) during a surveillance period of 12 months. The results were compared with those of RSV-negative children hospitalized with identical indications during the 3 peak months of the RSV epidemic (N = 91) or for the 3 months after the outbreak (N = 99). A high frequency of pneumonia and acute otitis media were found in both RSV-positive and RSV-negative children during the epidemic, but not in control patients after the epidemic. Bacterial infection, based on a significant rise of antibody titer and/or on detection of pneumococcal antigen in serum or urine, was observed in 39% of the children with RSV infection. The respective figures were 24% in RSV-negative children hospitalized during the epidemic and 8% after the epidemic. Our observations stress the role of RSV as a predisposing agent for secondary bacterial infection in the airways of children. The most common bacteria involved in the mixed RSV-bacterial infections were Streptococcus pneumoniae and Haemophilus influenzae, the latter being found only in pneumonic patients. The presence or absence of pneumonia or acute otitis media was not significantly correlated with evidence of pneumococcal infection. We conclude that a bacterial pathogen should be actively sought when managing patients with lower respiratory tract syndromes, especially in those who have evidence of RSV infection.

In the five year period between 1980 and 1984, 2146 adults and 172 neonates suffering from acute conjunctivitis underwent laboratory investigation for Chlamydia trachomatis (CT), Adenoviruses (AV), Herpes Simplex Virus (HSV) and pathogenic bacteria. Epidemiology and clinical features are presented and discussed. CT was detected in 29 per cent of neonates with conjunctivitis. 5.6 per cent of adults and older children investigated for follicular conjunctivitis were CT positive. There was a significant female preponderance among CT positive neonates of 1.9:1 (p less than 0.02). 91 per cent of neonates and 62 per cent of adults in whom CT was detected were receiving some sort of treatment. Serotypes 7, 3, 10, 4 and 8 were responsible in decreasing order of frequency for 96 per cent of AV infections. Serotype 7 was seen for the first time in an adult age distribution. HSV was isolated in 1.3 per cent of cases in the absence of typical lid or corneal lesions. Viral infection was not detected in any neonate. Bacterial infection was a more likely cause than CT in neonates if infection had persisted longer than 5 weeks (p much less than 0.001). Neonates with Staph aureus infection tended to present earlier in the course of disease than those with Haemophilus sp or Pneumococcus (p less than 0.05).

Mixed bacterial infection in meningitis is well-documented, but there have been few previous reports of mixed viral-bacterial meningitis. A retrospective analysis of the bacterial and viral cerebrospinal fluid (CSF) cultures from a 1-year period in a 315-bed children's hospital revealed 5 patients with mixed viral-bacterial meningitis among 276 patients with viral and/or bacterial culture-positive meningitis. These 5 accounted for 2.8% of the patients with positive CSF viral cultures and 4.8% of those with positive CSF bacterial cultures. All of the viruses were identified as enteroviruses, and the bacteria were Group B Streptococcus, Group D Salmonella, Streptococcus pneumoniae, Haemophilus influenzae type b and Staphylococcus aureus. The ages of the patients ranged from 10 days to 22 years. The clinical course of each of the illnesses was typical of bacterial meningitis. This relatively high frequency of mixed viral-bacterial meningitis could affect the utility of rapid viral diagnostic tests for CSF viruses.

This review examines an important bacterial infection in acquired immunodeficiency syndrome (AIDS). Despite occasional infections with bacteria such as Streptococcus pneumoniae, Haemophilus influenzae, Salmonella, and Nocardia in patients with AIDS, the primary problems of AIDS and invading bacterial infections center around mycobacteriosis. A unique feature of AIDS has been the common identification of disseminated infections with Mycobacterium avium-intracellulare. The following discussion examines our present understanding of this group of organisms and how they interact with the compromised host.

Analysis of 121 consecutive cases with infection of the nervous system showed that the majority were the granulomatous infections, tuberculosis and brucellosis (53 cases (44 per cent)). Thirty-nine patients had tuberculosis and 14 had brucellosis. The clinical and microbiological pattern of infection differs from that frequently reported from Western countries. Tuberculosis lesions presented with features of intracranial space occupying lesions (14), spinal cord compression (13) and lumbosacral root compression (1 child). Ten adults and one child had tuberculous meningitis. Pyogenic meningitis present in 38 cases (31 per cent), was most common in children. The infecting organism was identified in 26 patients; Gram-positive cocci in 17, Haemophilus influenzae in four and other Gram-negative organisms in five. Eleven patients had brain abscesses, caused by bacterial infection in eight, fungal infection in two and Toxoplasma gondii in one. Nineteen patients had clinical and pathological features of viral meningitis. Fourteen patients (12 per cent) died including six children with pyogenic meningitis.

We performed a prospective, randomized, placebo-controlled, double-blind clinical trial of antibiotic administration to treat possible occult bacteremia in febrile children. A total of 955 children aged 3 to 36 months with temperatures greater than or equal to 39.0 degrees C and no focal bacterial infection were enrolled at the emergency departments of two children's hospitals from January 1982 until July 1984. Blood samples for culture were obtained, and the children were randomly assigned to receive either oral amoxicillin or placebo and were restudied approximately 48 hours after enrollment. Data were also collected on 228 children who could not be randomly assigned. Twenty-seven of the randomly assigned children (2.8 percent) had bacteremic infections with pathogenic organisms (Streptococcus pneumoniae, Haemophilus influenzae, and salmonella). There were no differences in the incidence of major infectious morbidity associated with bacteremia between the antibiotic and placebo groups--2 of 19 patients (10.5 percent) in the antibiotic group and 1 of 8 (12.5 percent) in the placebo group--although the power for this comparison was low. Antibiotics reduced fever (P less than 0.005) and improved the clinical appearance (P = 0.07) in the children with bacteremia but not in those without bacteremia. Although there were no statistically significant differences in the incidence of side effects, diarrhea tended to occur more often in the patients treated with amoxicillin (15 vs. 11 percent, P less than 0.10). We conclude that our data do not support the routine use of standard oral doses of amoxicillin in febrile children who do not have evidence of focal bacterial disease.

Seven adult patients with nongonococcal polyarticular septic arthritis are presented with a literature review of the clinical features of polyarticular bacterial infection. Polyarticular septic arthritis occurred in 19% of reported cases of septic arthritis in adults. Similar to monoarticular disease, the knee was the most commonly affected joint, and Staphylococcus aureus was the most frequently isolated microorganism. Pneumococcus, group G streptococcus, and Hemophilus influenzae had an increased association with polyarticular infection. Five of our 7 patients had underlying rheumatic diseases and the immediate mortality rate was 57%. Review of the literature yielded an overall mortality of 23% for polyarticular septic arthritis compared to the 9% mortality of septic arthritis in general. The subset of patients with polyarticular infection superimposed on rheumatoid arthritis had a mortality rate of 56%.
