Although animal models of infection are associated with certain limitations in interpretation, properly performed studies provide important information for evaluating the efficacy of new antimicrobial agents in the treatment of human disease. The antibacterial efficacy of the newer quinolones, particularly ciprofloxacin, has undergone extensive evaluation in several animal models. Efficacy has been demonstrated in animal models of pneumonia, endocarditis, meningitis, skin and soft-tissue infections, septic arthritis, burn wound sepsis, empyema, intra-abdominal abscess, osteomyelitis, prostatitis, sinusitis, urinary tract infection, chronic gastroenteritis, granuloma pouch infection, and Pseudomonas septicemia. More recent studies have evaluated the efficacy of ciprofloxacin in animal models of tuberculosis and syphilis, as well as in infections caused by the intracellular pathogens Salmonella typhimurium, Legionella pneumophila, and Listeria monocytogenes.

We have treated 42 episodes of pediatric infections with sulbactam/ampicillin since 1987. Included were 9 cellulitis, 9 urinary tract infections, 5 cervical lymphadenitis, 4 meningitis, 2 thoracic empyema, 2 osteomyelitis, 2 sepsis, 1 furuncle, 1 perianal abscess, 1 dental abscess, 1 peritonsillitis, 1 salmonellosis, 1 shigellosis, 1 peritonitis, 1 suppurative thyroiditis, 1 infective endocarditis. Responsible pathogens were Escherichia coli in 8, Staphylococcus aureus in 6, Hemophilus influenzae in 2, Streptococcus pneumoniae in 3, Streptococcus viridans in 2, Staphylococcus epidermidis in 1, Bacteroides fragilis in 1, Salmonella D1 in 1, Shigella sonnei in 1, Klebsiella pneumoniae in 1, Enterobacter agglomerans in 1, Acinetobacter calcoaceticus in 1, Enterobacter cloacae in 1, group A beta-hemolytic streptococcus in 1, and polymicrobial infection in 4 cases. Thirty-nine out of 41 (95%) clinically evaluable patients cured and all (34/34) bacteriologically evaluable patients eradicated their pathogens after treatment with sulbactam/ampicillin. Side reactions were seen in five patients; one maculopapular skin rash, one hemolytic anemia, two diarrhea, and one liver function impairment plus leukopenia. All these reactions were transient and did not require interruption of therapy. These results indicate that sulbactam/ampicillin is safe and effective in the treatment of common pediatric infections beyond the neonatal period.

Streptococci of Lancefield group C colonize healthy individuals but infrequently cause invasive disease. Eight pediatric cases of infection due to group C streptococci were identified in a retrospective survey of a recent 6-year period at a children's hospital. An additional case of group C meningitis diagnosed in 1975 was included. These nine cases and 22 pediatric cases from the literature are presented to illustrate important points with respect to clinical presentations and complications and to show that these organisms can cause serious, sometimes fatal infection: pneumonitis, sinusitis, septicemia, endocarditis, osteomyelitis, and meningitis. Group C streptococci are described in terms of their biochemical properties, the infections they cause in animals, and their tendency to produce disease in humans. With increasingly frequent serologic grouping of non-group A beta-hemolytic streptococci, recognition of the role of specific non-group A streptococci is likely to increase. The antimicrobial agent of choice for infections due to group C streptococci is penicillin G. The minimum inhibitory and minimum bactericidal concentrations for the organism should be determined since penicillin tolerance may occur and may be responsible for the slow response to penicillin therapy in some cases.

Although the first Aeromonas strain was described by Zimmermann as early as in 1890, it took 60 years until Caselitz established human pathogenicity of strains then called "Vibrio jamaicensis". Since then, and especially in the last 10 years, there have been increasing numbers of reports on different infections caused by members of the genus Aeromonas. These include sepsis; meningitis; cellulitis; necrotizing fasciitis; ecthyma gangrenosum; pneumonia; peritonitis; conjunctivitis; corneal ulcer; endophthalmitis; osteomyelitis; suppurative arthritis; myositis; subphrenic abscess; liver abscess; cholecystitis and/or ascending cholangitis; urinary tract infection; endocarditis; ear, nose, and throat infections; balanitis; etc. The role of Aeromonas in gastrointestinal disease is very controversial. Increasing epidemiological data suggest that these organisms play a major role in enteric infections, but so far enteropathogenicity has not been demonstrable in experiments where volunteers were given high numbers of Aeromonas possessing different virulence factors. Virulence factors include hemolysin(s), enterotoxin(s), hemagglutinins, invasivity, and others; but these are not found more frequently in strains isolated from patients with diarrhea than from healthy controls. Whether there is a correlation between species and disease remains to be elucidated and requires more information about the taxonomy of this genus.

The pathophysiology and pathologic appearances of adult osteomyelitis are discussed, without reference to childhood hematogenous (metaphyseal) osteomyelitis or chronic osteomyelitis secondary to vascular phenomena such as diabetes or arteriosclerosis. Osteomyelitis as a feature of generalized sepsis in the immunocompromised patient is also excluded. The focus is on infection of the adult skeleton that occasionally arises spontaneously but more commonly presents as a complication of an open fracture or an operative procedure. The special features of adult osteomyelitis that are the result of the infection developing within the confined and rigid structure of the skeleton are highlighted. Lastly, the histopathology of osteomyelitis is examined in an effort to demonstrate the host bone's response to this injury.

A 15 year old patient with acute lymphoblastic leukemia, previously diagnosed as being a salmonella carrier, developed S. typhimurium sepsis after allogeneic bone marrow transplantation, in spite of pretreatment with chloramphenicol. Clinical improvement and termination of salmonella excretion were achieved by treatment with multiple antibiotics. Another patient with acute lymphoblastic leukemia, a 3 year old boy not previously identified as a salmonella carrier, also developed sepsis and osteomyelitis, together with pathological fractures during chemotherapy. Chloramphenicol, administered after isolation of S. typhimurium from blood cultures, led to resolution of the bony defects, complete recovery, and cessation of salmonella excretion. Selective cultures for salmonellae seem indicated in patients with malignant diseases, prior to chemotherapy.

Although short courses of 4-quinolones are effective in routine infections, longer courses are necessary for chronic, deep-seated sepsis. Oral 4-quinolones exhibit efficacy equal to that of traditional parenteral regimens against osteomyelitis caused by gram-negative pathogens and have proved successful against chronic prostatitis and suppurative otorhinologic infections. The efficacy of these agents in the prophylaxis of urinary tract infection, travelers' diarrhea, and infections in neutropenic patients suggests other indications for potential widespread, long-term use. It is therefore important that the tolerability of regimens extending from 3-6 weeks to greater than or equal to 12 months has proved excellent. Potentially serious adverse reactions (including arthritis, cataract formation, and mutagenesis) noted in chronic animal toxicity or in vitro studies have no apparent human counterparts. However, experience is limited, and restrictions on use of the quinolones in children--except where real benefit outweighs theoretical risk--should not yet be abandoned.

Pressure ulcers are a common problem for older persons. Complications associated with pressure ulcers include infection and even death for some patients. Pressure is the primary pathogenic factor, but shearing forces, friction, and moisture are also important. Immobility, nutritional status, and age-related factors seem to be significant risk factors. Preventive care includes use of assessment tools to identify high risk patients, frequent repositioning, air or foam mattresses that reduce pressure over bony prominences, as well as careful attention to optimizing the overall patient condition. When pressure ulcers do develop, the treatment plan should include adequate nutrition including protein, vitamin C, and zinc supplements as indicated; systemic antibiotics for sepsis, cellulitis, osteomyelitis, or the prevention of bacterial endocarditis; and local wound care that eliminates necrotic tissue, decreases bacterial load, and provides a physiologic, pressure-free environment allowing the wound to heal. Specialized beds may be considered in some patients, particularly those with larger ulcers. Surgery is an option in older persons who are operative candidates. For some patients with pressure ulcers, appropriate treatment goals may focus on providing comfort rather than curing the ulcer.

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.
