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.

Haemophilus influenzae is a gram-negative rod, causing severe infections in childhood, including meningitis, sepsis, epiglottits, pneumonia and otitis. Most of the invasive infections are due to serotype b. Since ampicillin-resistance is increasing, modern cephalosporines like cefotaxime and ceftriaxone are the antibiotics of choice in severe disease. Bacterial meningitis due to Haemophilus influenzae and epiglottitis are both still life-threatening diseases with a lethality of 5% to 25%, and there are severe sequelae in 35% of meningitis cases. Efforts have been made to develop efficacious vaccines. While immunogenicity of type b polysaccharide was low in the high-risk age (below 18 months), conjugated vaccines with either diphtheria-toxoid or Neisseria meningitis outer membrane protein and the Hib polysaccharide were found to be strongly immunogenic even in the first months of life. These vaccines show every few side-effects and can easily be combined with other immunizations such as DPT and DT. Thus, the incidence of invasive infections due to Haemophilus influenzae type b might decline in future.

In a multicenter randomized trial, 107 children with bacterial meningitis were initially given either cefuroxime or ampicillin plus chloramphenicol. Patients were alternately assigned to 7- or 10-day courses of the designated antimicrobial regimen. CSF isolates included Haemophilus influenzae type b (89, of which 25% were beta-lactamase positive), Streptococcus pneumoniae, and Neisseria meningitidis. Although mean CSF bactericidal titers against Haemophilus isolates were 1:6 in each treatment group, H. influenzae was cultured from CSF in four of 39 patients receiving cefuroxime, 24 to 48 hours after initiation of therapy, compared with none of 40 patients given ampicillin plus chloramphenicol (P = 0.11). Clinical cure rates were similar (95%); one death occurred in each group. One child given cefuroxime had persistent meningitis after 5 days of therapy, and mastoiditis with secondary bacteremia developed in one on day 10. Three patients had relapse or reinfection. One patient who received cefuroxime for 10 days had a relapse of epiglottitis 17 days later, and of the patients given ampicillin plus chloramphenicol, one had a relapse of meningitis 1 week after 7 days of therapy, and bacteremia developed in one 42 days after completion of 10 days of therapy. No increase in either in-hospital complications or relapses occurred with a 7-day treatment course. Proof of the equivalence of the antibiotic regimens and the efficacy of 7-day courses of treatment, as well as the consequences of delayed CSF sterilization, will require additional investigation.

During 1971-77 the incidence of bacterial meningitis among Alaskan Eskimos was 84.4 cases per 100 000 population per year, which is more than 10 times that for most other U.S. populations. Haemophilus influenzae (HI) accounted for 68% of meningitis cases. The average annual incidence of HI disease per 100 000 children below 5 years of age was 409 for patients with meningitis only and 491 for patients with all systemic HI disease. Children with HI meningitis in Alaska tended to be younger than those in other U.S. populations, 98% of the children affected being less than 18 months of age. The risk for all HI disease was 2.4% during the first year of life. The spectrum of HI disease in Alaska differs from that in other populations in that no patient had epiglottitis and 5% of children had recurrent HI disease. Alaskan newborns and children over 4 years old had HI anticapsular antibody titres that were nearly thrice those for children of similar ages in other U.S. populations (p less than 0.005). The pharyngeal carriage of HI type b (5%) and the rectal carriage of Escherichia coli K100 (2%), an organism with a capsule antigenically similar to HI type b, did not differ from those in other populations. The high incidence of disease almost exclusively in the very young and the early development of antibody in this population suggest that the high rate of disease is due to early exposure to HI type b rather than to an unusual susceptibility to HI type b.

Hemophilus influenzae type b (Hib) is the most common cause of bacterial meningitis among children under 5 years old. Hib is also responsible for other invasive diseases including epiglottitis, cellulitis, sepsis, pneumonia, and osteomyelitis. A child's cumulative risk of systemic Hib disease during the first 5 years of life is approximately 1 in 200. A polysaccharide Hib vaccine was first marketed in 1985, and newer, more effective conjugated vaccines have been licensed since 1987. Immunization schedules have included increasingly younger children. No studies have been published that analyze the effects of a vigorous immunization program on a sample population representative of the United States at large. Records of pediatric patients ages 5 years and younger who were treated for Hib meningitis or epiglottitis (N = 373) at all U.S. Army medical facilities between 1986 and 1991 were reviewed. The combined incidence of these diseases declined by more than 86% in the study group during this period. The largest decrease occurred in infants less than 1 year old, before vaccines were licensed for use in this group. Meanwhile, the number of cases of bacterial meningitis due to other organisms in this cohort remained unchanged. Economic modeling validates the cost-effectiveness of vaccination. The impact of these preliminary trends on health care systems and otolaryngology-head and neck surgery will be significant. Almost two thirds of Hib disease has involved infants under 15 months old, for whom a conjugated vaccine has been available only since October 1990. The change in disease frequency will have substantial bearing on training programs, because management of neurologic sequelae and the emergent airway require the expertise of otolaryngologists. In the face of medical onslaught, Hib invasive disease is in retreat.

Epidemiological surveillance programs have shown that before the introduction of effective vaccines, Haemophilus influenzae type b (Hib) was the primary pathogen associated with bacterial meningitis in children. Vaccines composed of the bacterium's polysaccharide conjugated onto protein carriers began to be introduced into routine health care practices for infants as early as 1989 in some European countries. Continued introduction in industrialized nations, including the United States in late 1990, has resulted in the rapid decline in the incidence of reported invasive Hib disease. Follow-up surveillance studies show that (a) the decline in the incidence of Hib disease is temporally related to the introduction of effective vaccines, (b) the decline in Hib epiglottitis preceded the decline in meningitis in the United States, (c) the incidence of disease declined in children under the age of 5 years but remained constant in older children and adults, (d) other bacterial pathogens are now the primary causative agents of infant meningitis and epiglottitis even though the incidence of disease caused by these other pathogens has not changed, and (e) the pharyngeal carriage rate of Hib in children has declined without any evidence of an increase in the carriage of non-type b strains or other pathogens. The introduction of effective conjugate vaccines appears to protect at-risk children from invasive Hib disease as well as reduce the opportunities for interpersonal transmission of this bacterium. In addition, Hib conjugate vaccine utilization has benefited society through economic savings.

Systemic donor infection is regarded as being an absolute contraindication to cadaveric organ donation for transplantation. This is largely due to fear of transmitting pathogenic organisms to the immunosuppressed recipient. However, due to the current shortage of organs available for transplantation, clinicians are faced with the option of using organs from 'non-ideal' donors, such as those patients with documented evidence of infection. We report the successful outcome of six orthotopic liver transplants, 11 renal transplants, one combined heart lung transplant and one simultaneous kidney and pancreas transplant with organs from eight donors in whom bacterial meningitis (n = 7) and acute bacterial epiglottitis (n = 1) were the antecedent causes of death.

This paper reviews the role of Haemophilus influenzae type b (Hib) as one of the most important pathogens causing invasive infectious diseases, especially in the first 2 years of life. In developing countries H. influenzae is responsible for 30% of all pneumonia cases with positive cultures and for 20% to 60% of all bacterial meningitis cases. In this study we compared Brazilian and international epidemiologic data obtained from several bibliographic databases (MEDLINE, 1966 to 1995; LILACS, 1982 to 1995; Thesis Databank, 1980 to 1995; and Dissertation Abstracts, 1988 to 1994). The incidence of Hib infection in Brazil was analyzed for individual states and for different ages, including within the first year of life. Meningitis cases were used as an incidence marker because of the difficulty in identifying the causative organism in such other infections as pneumonia, osteomyelitis, epiglottitis, cellulitis, and endocarditis. Our analysis showed that the nationwide Brazilian data masked the regional incidence and lethality of H. influenzae. For example, in 1991 the national incidence was 18.4 per 100,000 children under 1 year of age. In the same period, the Federal District had an incidence of 175 per 100,000 among children between 4 and 6 months of age. Similarly, the North of Brazil had a 35% case fatality rate in 1987, whereas the rate was 22% for Brazil as a whole. This study raises issues concerning the relevant epidemiologic factors associated with Hib infection and the costs and benefits of prophylaxis and vaccination in the age groups most at risk.

The emergence of beta-lactamase-mediated resistance to established beta-lactam antibiotics prompted the development of beta-lactamase inhibitors for co-administration. Ampicillin has been combined with sulbactam for both parenteral and oral (as the mutual pro-drug sultamicillin) administration. The combination is active in vitro against a wide variety of Gram-positive and Gram-negative pathogens, including aerobic and anaerobic organisms. In clinical trials, ampicillin/sulbactam has proved clinically and bacteriologically effective against a variety of frequently encountered pediatric infections, including mild-to-moderate upper respiratory tract infections (acute otitis media, sinusitis, pharyngitis, and tonsillitis), severe post-operative and intra-abdominal infections, periorbital infections (which, left untreated, can lead to blindness, brain abscess, or death), acute epiglottitis, bacterial meningitis, and brain abscess. Ampicillin/sulbactam has also proved effective in the prevention of post-operative surgical infections in pediatric patients. The clinical efficacy profile of ampicillin/sulbactam and sultamicillin, combined with their excellent tolerability profile, make these agents attractive options for the management of many life-threatening infections in pediatric patients.

Vaccines against Haemophilus influenzae type B (HI) and Streptococcus pneumoniae (SP) have dramatically reduced the incidence of bacterial meningitis (due to both HI and SP) and epiglottitis (due to HI) in childhood. The effects of these vaccines on other conditions, however, are less clear. We report an analysis of the effect of serial deployment of various HI and SP vaccines over a 25-year period, involving an examination of over half a million pediatric hospitalizations occurring in Army hospitals worldwide. We show that, in marked contrast to the reduction in the number of meningitis and epiglottitis cases, the disease burden of orbital and facial cellulitis--conditions oft attributed to HI and SP-did not diminish.
