Clindamycin and gentamicin were used in combination to treat 107 patients empirically for suspected aerobic-anaerobic sepsis. All patients were seriously ill and required initiation of treatment before results of cultures could be obtained. Infections included intraabdominal sepsis, hospital-acquired aspiration pneumonia, and soft tissue infections. Exudate cultured from 65 patients showed that the prediction of a mixed aerobic-anaerobic flora was correct in 46 patients (71%). Isolates from exudate included Escherichia coli, Bacteroides fragilis, clostridia, peptostreptococci, Proteus species, Klebsiella species, and Staphylococcus aureus. In 29 patients with bacteremia, the most frequent blood culture isolate was B. fragilis. Analysis of response to treatment showed that 92 patients were cured, five could not be evaluated adequately, and 10 failed to respond to therapy. Therapeutic failure primarily resulted from overwhelming sepsis, despite susceptibility of the pathogens to prescribed antibiotics.

Among the main aspects to be considered when treating burns, the problem of infection control remains unsolved. Considerable financial resources are needed to prevent the transmission of organisms. To justify such investments in buildings and antiseptic measures, an extensive epidemiological hospital study was carried out from 1970 to 1974, involving 930 patients, and more than 25,000 wound biopsies as well as 10,000 contact cultures and environmental swabs. Bacteria from the environment of severly burned patients were counted every week. Serotyping was used for a specialized study of Pseudomonas aeruginosa. In 200 patients wound organisms were counted. The most important organisms were: Streptococcaceae (pyogenic streptococci, less frequently faecal and salivary streptococci). Pseudomonadaceae, Enterobacteriaceae, and Micrococcaceae (especially Micrococcus aureus). Povidon iodine, gentamicin and silver sulfadiazine were used for local disinfection. Antibiotics used were gentamicin, carbenicillin and polymyxin. Whereas from 1970 to 1972 P. aeruginosa was the predominant organism found in wounds, other gram-positive organisms increased from 1972 on. Wounds were colonized mainly in the course of the first two weeks of treatment. Special studies regarding P. aeruginosa revealed a predominance of serotypes 5 and 13 between 1970 and 1973, whereas types brought into the hospital were dominant from 1973 on. An analysis of furniture and equipment, water faucets and drains showed that Pseudomonas strains found in the water did not coincide with those found in wounds. Therefore, a contamination from this source seems unlikely. Strains found on furniture and equipment, however, also appeared in the wound flora. When the therapeutic routine was changed (to prevent patients passing through common treatment areas such as bathrooms and dressing areas) hospital organisms 5 and 13 could be eliminated almost completely. Thus, it is possible to achieve a considerable reduction in the rate of cross-infection among patients by, for instance, excluding common treatment areas from the therapy programme. Nevertheless, in the majority of cases wounds will still be colonized, in particular by bacteria that were already in the anal region or on the skin before the patient was injured. For this reason, the elimination of such organisms by topical bactericidal agents constitutes an an important factor in efforts to reduce the rate of septicaemic complications. In view of the persisting high mortality due to generalized infections this therapeutic aspect must also be exploited thoroughly in the future. Although in comparative studies of topical therapy using povidon iodine, silver sulfadiazine and gentamicin, organisms did appear in the course of the first two weeks; in the case of the PVP-I the colonization never reached 10(5) organisms per cm2, i.e. the danger threshold for generalized sepsis. There was no evidence of a correlation between number of organisms and depth of burns.

The catabolic effects of starvation alone, or starvation in the presence of pneumococcal sepsis, were compared in rats whose skeletal muscle protein had been tagged 14 days earlier with 14C-phenylalanine. In a fed rat, protein catabolism (as estimated by expired 14CO2) is not constant throughout the day but is highest during the dark hours. Starvation is associated with accelerated protein catabolism and a gradual loss of periodicity. Infection increases the rate of catabolism still further and results in a complete loss of periodicity.

Infection in prosthetic grafts of the aorta and in the groin present different problems. Retroperitoneal sepsis must be treated by total removal of the graft. This is probably equally true for acutely infected grafts seen in enteric fistula. The surgical technique described can be performed in one stage. The principles of treatment for groin infections are the same as for infections associated with prosthetic grafts. The hazard is more to limb than to life, since the infection tends to point outward in the groin and thus be confined. The technique for dealing with groin infections, as presented, is straightforward.

Severe burns are followed by a shock period of more than 48 h. Insufficient fluid replacement may lead to serious organic damage. Protein losses are high. Cardio-respiratory complications are frequent. Infection and sepsis are still frequent causes of death. Skin damage requires extensive operations for debridement and skin replacement, and blood losses must be replaced simultaneously.

The prevalence of obligate anaerobes was studied prospectively in 60 patients with severe sepsis of intra-abdominal, soft tissue, female genital or oropulmonary origin. In addition, the efficacy of clindamycin (for anaerobes) plus gentamicin (for aerobic bacteria, especially coliforms) as initial empiric therapy in these patients was evaluated. Among 54 patients with cultural proof of infection, anaerobic pathogens were recovered from 52%. Nineteen patients had bacteremia; Bacteroides fragilis and Klebsiella pneumoniae were the most prevalent pathogens, being isolated in five patients each. Infection was eradicated in 56 of the 60 patients (93%). Mortality related to sepsis was 7% in the entire group, 16% in patients with bacteremia and 2% in patients without bacteremia. Eighty-five percent of aerobic isolates tested were susceptible in vitro to either gentamicin or clindamycin; 97% of anaerobic isolates were inhibited by 5 mug/ml of clindamycin.

Complications after heart valve replacement remain a substantial source of morbidity and mortality despite continuing advances in surgical care and prosthetic design. Infectious endocarditis occurs in about 4 percent of patients and may appear early (within 60 days) or late after operation. Endocarditis of early onset is commonly due to staphylococcal, fungal or gram-negative organisms and is fatal in 70 percent or more of cases. Infection of late onset is more often of streptococcal origin and the mortality rate is lower, about 35 percent. With either type, prompt recognition, vigorous and appropriate antimicrobial therapy and early consideration of surgical intervention are crucial. The postperfusion and postpericardiotomy syndromes are relatively common and relatively benign syndromes associated with postoperative fever. Their recognition is important to prevent confusion with endocarditis or sepsis and thus to reassure the patient and physician. Treatment is primarily symptomatic. Intravascular hemolysis occurs with most prosthetic heart valves but is more common with certain prostheses and with paraprosthetic valve regurgitation, with significant hemolytic anemia in 5 to 15 percent. Oral iron replacement therapy is effective in the majority of patients, but occasionally blood transfusion or reoperation for leak around the prosthesis is necessary. Prosthesis dysfunction due to thrombus may be recognized clinically by recurrence of heart failure, syncope, cardiomegaly and altered prosthetic valve sounds or new murmurs. Hemodynamic studies verify the diagnosis, and prompt reoperation is indicated for this potentially lethal problem. Systemic embolization has decreased markedly with the introduction of cloth-covered prostheses and is frequently related to erratic or ineffective anticoagulant therapy. We continue to recommend anticoagulant therapy for all patients with prosthetic heart valves unless there is a major contraindication.

S-fimbriated Escherichia coli, which cause sepsis and meningitis in the newborn, bind to sialic acid-containing glycoprotein structures on the surface of human buccal epithelial cells. The dependence of this binding on host age was examined. S-fimbriated E. coli adhered in comparable numbers to cells in newborns, infants, children and adults (23.0 +/- 8.6; 23.1 +/- 11.5; 24.7 +/- 7.9; 28.9 +/- 8.8). Thus, the increased susceptibility of neonates to infections caused by S-fimbriated E. coli cannot be explained by enhanced adhesion to epithelial cells.

In order to define the role of intracranial and extracranial complications in determining outcome from severe head injury, 734 patients from the Traumatic Coma Data Bank were analyzed. Nine classes of intracranial and 13 classes of extracranial complications occurring within the first 14 days after admission were analyzed, while controlling for age, admission Glasgow Coma Scale motor score, early hypoxia or hypotension, and severe extracranial trauma. Outcome for survivors was based on the last recorded Glasgow Outcome Scale score, obtained a median of 521 days after injury. Intracranial complications did not significantly alter outcome for the study group. Of the extracranial complications, pulmonary, cardiovascular, coagulation, and electrolyte disorders occurred most frequently at 2 to 4 days. Infections developed later, peaking at 5 to 11 days. Gastrointestinal, renal, and hepatic complications followed no specific time course. Electrolyte abnormalities were the most frequent occurrence (59% of patients) but did not alter outcome. Pulmonary infections (41%), shock (29%, systemic blood pressure < or = 90 mm Hg for 30 minutes or more), coagulopathy (19%), and septicemia (10%) were significant independent predictors of an unfavorable outcome. Backward-elimination, stepwise logistic regression modeling indicated that the estimated reduction of unfavorable outcome was 2.9% for the elimination of pneumonia, 3.1% for coagulation disturbances, 1.5% for septicemia, and 9.3% for shock. These data suggest that extracranial complications are highly influential in determining the outcome from severe head injury and that significant improvements in outcome in a sizeable proportion of patients could be accomplished by improving the ability to prevent or reverse pneumonia, hypotension, coagulopathy, and sepsis.

The neutropenia often seen in infants of hypertensive mothers (IHMs) at < 12 hours of age has been associated with nosocomial infection in the first 18 days of life. To assess maternal hypertension as an independent factor for nosocomial infection, we compared 101 low birth weight (< or = 2.00 kg) IHMs to a concurrent birth weight-matched group of infants of normotensive mothers (INMs). Infants without differential leukocyte counts at < 12 hours of age were excluded, leaving 93 IHMs and 98 INMs. The incidence of neutropenia at < 12 hours among IHMs was not significantly different from that among INMs (42/92 (45%) vs 37/98 (38%)). Nosocomial infection was more frequent in neutropenic IHMs than in neutropenic INMs (12/42 vs 2/37; p = 0.007). Infection in IHMs included omphalitis (2 infants), pneumonia (4), and sepsis with or without meningitis (6); INMs had cellulitis (1) and sepsis (1). The underlying mechanism(s) for this predisposition remains to be elucidated, although limited data suggest that neutropenia may be more severe and prolonged among IHMs.
