Fifteen male hemodialysis patients developed 21 episodes of S. aureus bacteremia. Infections involving vascular access were responsible for 65% of initial bacteremias. The arteriovenous fistula was the most prevalent type of access used, and thus was responsible for the majority of these illnesses. Phage typing indicated that recurrent episodes were due to reinfection rather than relapse. Complications included endocarditis, osteomyelitis, septic embolism, and pericarditis. One patient died of infectious complications. It is recommended that hemodialysis patients developing bacteremia due to S. aureus receive at least 6 weeks of beta lactamase-resistant antimicrobial therapy.

During a five year period, 28 episodes of spontaneous bacterial peritonitis were documented. The number of cases recognized annually increased during the study period. Clinical and laboratory features of spontaneous bacterial peritonitis were similar to those previously reported; however, mortality was considerably lower (57 per cent). Factors associated with adverse prognosis were increasing hepatic encephalopathy, more than 85 per cent granulocytes in peripheral blood or ascitic fluid, total bilirubin greater than 8 mg/dl and serum albumin less than 2.5 g/dl. Temperature greater than 38 degrees C was associated with increased survival. Infection by enteric organisms was associated with higher mortality than infection by nonenteric organisms. Unexpectedly, patients with bacteremia fared no worse than those whose blood remained sterile. The data suggest that in patients with leukocyte counts greater than 1,000 cells/mm3 and more than 85 per cent granulocytes in their ascitic fluid, the likelihood of spontaneous bacterial peritonitis is high. Such patients deserve empiric antibiotic therapy pending the results of appropriate cultures.

A patient with Salmonella typhi bacteremia was sucessfully treated with cefamandole, a new cephalosporin derivative. Infection has not recurred during 6 months of follow-up observation. Minimum inhibitory concentrations and minimum bactericidal concentrations of cefamandole, cephalothin, ampicillin, and chloramphenicol were compared against 26 strains of S. typhi. All the strains were susceptible to cefamandole in vitro. Seven of the strains were resistant to chloramphenicol, and another seven were resistant to both chloramphenicol and ampicillin. Cefamandole appears to warrant further clinical trial for the treatment of typhoid fever.

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.

Semiquantitative estimates of circulating endotoxin were performed by the limulus test in patients suffering from typhoid fever and other salmonelloses. The test was positive in a large number of cases. However, no clearcut correlation was found between existence of endotoxemia, as such, and pyrexia. A correlation with recent bacteremia was found for highest levels of endotoxin activity. In minor salmonelloses a striking prevalence of positive cases was observed in the age group under one year. These findings were discussed in relation to the diagnostic and pathogenetic facets of the problem.

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.

A retrospective study on infections was done on 131 patients (predominately adults) undergoing splenectomy with a median follow-up to 11 months. 43 patients died, and 23 of them were infected. Three succumbed primarily from their infection; in 9 the infection was a contributing factor; and 11 died primarily from their underlying disease with an associated infection. 64 patients had lymphoreticular malignancies, 53 had a nonmalignant condition and 14 had carcinomas. Infection rates were 42%, 42%, and 21% respectively. Bacteremia rates (all in adults) were were 5%, 4%, and 7% respectively. Over four-fifths of the infections were hospital acquired. 12 of 14 community onset infections occurred in patients with lymphoreticular malignancies.

Three case reports of infected subdural hematoma are presented, two with Salmonellae and one with Escherichia. Infection of such hematomas most often occurs during bacteremia, and the area of infection is limited by the existing hematoma membrane. Clincally, fever, headache, nuchal rigidity, and focal neurological signs, especially in a patient with previous head trauma, suggest subdural infection. Treatment consists of drainage and systemic antibiotics. These case reports demonstrate the clinical features of this rarely reported entity, and especially illustrate the need for careful bacteriologic identification in suspected cases.

A 7 and one-half yr-old girl developed bacteremia from S. marcescens following debanding of the pulmonary artery and closure of multiple ventricular septal defects with a Dacron patch and multiple Teflon pledgets. The site of entry was probably a radial arterial catheter left in place for 8 days. Infection was eradicated by a combination of gentamicin and carbenicillin over a 4-wk period. Of 12 cases of postoperative Serratia bacteremia in adults following valve replacement, only four survived. Antibiotics of proven effectiveness against the specific isolated Serratia strain, prompt therapy sustained for 6 wk offers the prospect for cure of this serious complication of cardiac surgery.

Topical chemotherapy, prompt excision, and timely closure of the burn wound have significantly reduced the occurrence of invasive burn wound infection and its related mortality. Since wound protection is imperfect and invasive wound infection may still occur in patients with massive burns in whom wound closure is delayed, scheduled wound surveillance and biopsy monitoring are necessary to assess the microbial status of the burn wound and identify wound infections caused by resistant bacteria or non-bacterial opportunists at a stage when therapeutic intervention can control the process. As a reflection of the systemic immunosuppressive effects of burn injury, infection remains the most common cause of morbidity and mortality even though the occurrence of wound infections has been significantly decreased. Pneumonia is the most frequent infection occurring in burn patients today but the improvements in patient management, wound care, and infection control have made bronchopneumonia the most common form of this infection and gram-positive organisms the most common causative agents. The organisms causing bacteremia that exert a species specific effect on the mortality related to extent of burn injury and patient age have changed in concert with changes in wound flora. Infection control procedures, including scheduled surveillance cultures, utilization of cohort patient care methodology, strict enforcement of patient and staff hygiene, and patient monitoring have been effective in eliminating endemic resistant microbial strains, preventing the establishment of newly introduced resistant organisms, diagnosing infection in a timely fashion, instituting antibiotic and other necessary therapy in a prompt manner, and documenting the effectiveness of present day burn patient care and the improved survival of burn patients.
