Five cases of neonatal infective endocarditis are reported. The mitral, tricuspid and pulmonary valves were involved either alone or in association. The predisposing factors were multiple: umbilical catheter, respiratory distress with assisted ventilation, septicemia, osteoarthritis or gastroenteritis. Only one child had a minor cardiac malformation. The causal organism was a staphylococcus aureus in all cases. All children had disseminated intravascular coagulation and a cardiac murmur. The diagnosis was confirmed by echocardiographic demonstration of bacterial vegetations. Three of the 5 children died despite long-term antibiotic therapy. In one case, a vegetation embolised to the pulmonary artery. In the two cured neonates the vegetations disappeared. These cases illustrate the value of echocardiography which should be performed in all neonates with septicemia or disseminated intravascular coagulation, especially when there is an associated cardiac murmur.

Canine saliva was tested for its bactericidal effects against pathogens relevant to the presumed hygienic functions of maternal grooming of the mammary and anogenital areas and licking of wounds. Both female and male saliva were bactericidal against Escherichia coli and Streptococcus canis but only slightly, and nonsignificantly, bactericidal against coagulase positive staphylococcus and Pseudomonas aeruginosa. E. coli is the cause of highly fatal coliform enteritis of neonatal mammals and E. coli and S. canis are the main pathogens implicated in neonatal septicemia of dogs. The bactericidal effects of saliva would facilitate the hygienic function of maternal licking of the mammary and anogenital areas in protecting newborns from these diseases. E. coli and S. canis along with coagulase positive staphylococcus and P. aeruginosa are among the common wound contaminants of dogs. Wound licking, and the application of saliva, would thus reduce wound contamination by E. coli and S. canis. The resistance of staphylococcus to bactericidal effects of saliva may be a factor in the high frequency (46 percent) with which coagulase positive staphylococcus was isolated from wounds compared with much lower frequency (9-17 percent) with which E. coli and S. canis were isolated.

There is little data to support the efficacy of prophylactic antibiotics in traumatology. In closed fractures three randomized controlled studies using a 1-3 day prophylaxis with Cephalosporins of the first or second generation or a Penicillinase-resistent Penicillin demonstrated a reduction of the infection rate. For the Cephalosporins of the second generation it was shown, that a single dose was less efficient than five repeated applications over 24 hours. In hip-fractures a prophylaxis with Cephalothin or Cefotiam reduced the frequency of infections when compared with controls. In open fractures a treatment over 10 days using Cephalothin or Isoxazolyl-Penicillin showed a significant drop of the infection rate. If however the fractures were not treated using the principles of rigid internal fixation and were covered with Dicloxacillin over 2 days only there was no significant improvement. A multicenter study finally indicates that a one day course of cefonicid sodium is not inferior to a prolonged course of antibiotics for prevention of early postoperative fracture-site infections. We conclude, that open and closed fractures can profit from antibiotic prophylaxis which starts immediately before surgery and is continued over 24 hours. We favour Isoxazolyl-Penicillin because of its efficacy against staphylococcus aureus and epidermidis which predominate in early infection. In established bone and soft tissue infections antibiotics are used when there is local spreading, sepsis, involvement of joints or when reinterventions in the infectious focus are necessary. In these cases bacteriological testing in the laboratory is essential for the selection of antibiotics. Local application of antibiotics in irrigation-drainage solutions can not be recommended. PMMA-chains serve as temporary spacers, but should be removed early before their extraction becomes difficult and resistant bacteria develop. When defects are closed with cancellous bone or soft tissues the use of Gentamycin-fleece or Taurolin-gels is recommended.

One hundred thirty-three febrile episodes in 115 neutropenic patients with hematologic malignancies were empirically treated with ceftriaxone and amikacin in a single daily dose. An indwelling central venous catheter (CVC) was present in 44 cases. Septicemia was documented in 18 (41%) patients with CVC (13 gram-positive, 5 gram-negative and 1 fungus) and in 30 (34%) patients without CVC (19 gram-positive, 10 gram-negative and 2 fungi). Coagulase-negative staphylococcus was observed in 10 out of 19 blood isolates in the presence of a CVC and in 6 out of 31 blood isolates in patients without CVC. Empiric therapy was successful in 56.4% of cases. Improvement after the addition of vancomycin or teicoplanin was observed in 38.6% of cases with a CVC and in 13.5% of those without (p less than 0.02). Only two patients died from gram negative septicemia, and the substitution of ceftriaxone with another beta-lactam was necessary in only 6% of the cases. Empiric therapy with single daily-dose ceftriaxone and amikacin appears to be effective in febrile neutropenic patients; our data, however, show the high incidence of Staphylococcus epidermidis septicemia and the frequent need to add an anti-gram-positive drug in patients with an indwelling CVC.

From 1974 to 1984, 46 patients underwent emergency surgery for acute native valve endocarditis. Urgent valve replacement was necessary because of rapid hemodynamic deterioration in 34 (73%), uncontrolled sepsis plus heart failure in 9 (19%), and life-threatening emboli in 3 (7%) patients. At the time of surgery 23 patients (50%) were in NYHA functional class IV, 20 in Class III, and 3 in class II. Streptococcus was the most common organism encountered, followed by staphylococcus. Thirty-four cases presented severe aortic regurgitation, 3 mitral incompetence, 8 mitral plus aortic insufficiency, and one aortic plus tricuspid insufficiency. Operative mortality rate was 17% (8/46). Most deaths were due to preoperative multiple system deterioration, especially in cases with lesions of both the aortic and mitral valves, and were unrelated to the duration of preoperative antibiotic therapy. The postoperative observation period of long-term survival is from 6 to 102 months (= 44 months). There were 7 late deaths. The actuarial survival, including operative mortality, is 67%. Twenty-two patients are now in NYHA class II, 6 in class III. The duration of postoperative antibiotic treatment (6 weeks in our series) seems to be important for the prevention of reinfection, early surgery is of great benefit; our 31 survivors showed an excellent clinical improvement.

A prospective study on major bacterial infections (MBI) has been made over a six-month period in a neonatal unit. Incidence of MBI was 6.8 per 1,000 live births. Rates were significantly higher in low (57/1,000) and very low-birth-weight newborns (200/1,000). Septicemia occurred most frequently with group B hemolyticus streptococcus and staphylococcus aureus as the commonest infecting organisms. In 19/33 haematologic studies abnormal neutrophilic cell counts, thrombocytopenia or both were seen. Case/fatality rate was 50% in this series.

475 samples taken from newborn infants hospitalized at "William Soler" Pediatric Teaching Hospital between January-June 1987 are studied, with the view to determine both localized and generalized sepsis. The total of positive samples was 41.3%. Enterobacteria were the organisms most frequently isolated. The coagulase-negative staphylococcus was the most frequently found in systemic sepsis (25.9%). It was demonstrated that the antibiotics with most effectiveness against enterobacteria were amikacin (97.5%) and Gentamicin (98.2%).

Clinical and bacteriological data of 145 inpatients with septicemia, treated at the hospital of Chiba University School of Medicine from 1972 to 1987, were reviewed by dividing them into three stages. (stages I: 1972-76, stage II: 1978-82, stage III: 1983-87) Patients with underlying diseases have been increasing: 91.8% of the total patients in stage III. Among the patients with underlying diseases, malignant and hematological diseases occupied about 60%, and in the other diseases, congenital heart diseases have been increasing in number. As to the organisms isolated, gram positive bacteria have increased, while gram negative bacteria have decreased. In stage III, the rate of gram positive organisms and gram negative ones accounted for 43.1% and 41.2% of all the isolates from the septic patients with malignant & hematological diseases, respectively. In patients with malignant & hematological diseases, alpha-streptococcus, coagulase-negative staphylococcus, and Fusobacterium sp. have been increasing, whereas, Escherichia coli, Enterobacter sp., Klebsiella sp., and Pseudomonas aeruginosa decreasing. In patients with other underlying diseases, S. aureus, CNS, and non Fermenters have been increasing. Among the patients without underlying diseases, gram positive bacteria accounted for the major part. The decrease of gram negative organisms in patients with malignant and hematological diseases may partially depend on the introduction of polymixin B as the drug of gut decontamination. The outcome of septicemia in the patients with malignant & hematological diseases has been markedly improving through all the three stages. During stage III, episode mortality and case mortality rate proved to be 23% and 31%, respectively. The introduction of the third generation cephems has decreased the mortality rate for gram negative organisms and contributed to the improvement of the total prognosis. The prognosis was worst in the case of P. aeruginosa, showing a mortality rate of 50% during stage III. Coincidence rate of blood and other cultures have been largest in the case of P. aeruginosa, so, the drug sensitivity of the strain cultured from other sites is sometimes useful in the choice of antibiotics.

Infective endocarditis, both in the native and prosthetic valve, presents a tremendous challenge to the cardiologist and cardiovascular surgeon, as well as the infection specialist. The timing of surgery is critical but it would appear that aggressive surgical intervention is indicated when there is persistent sepsis, continuing congestive heart failure, signs of nonfatal emboli, or in association with certain organisms such as staphylococcus, pseudomonas, or fungal organisms. Cardiac catheterization would not appear to add greatly to the diagnosis except to document the presence of coronary artery disease. The risk of surgery in patients with no annular abscess is low but the recurrence rate tends to be highly dependent on the organism. Similarly, patients who have annular abscesses tend to provide the greatest challenge for the surgeon and despite the use of newer prosthetic and biological prostheses and an overall more aggressive approach, this pathological entity, particularly in conjunction with prosthetic valve endocarditis, has a high mortality and a high recurrence rate.

A 33-year-old woman was admitted as an emergency case because of shock condition after delivery. Physical examination revealed fever, cyanosis and coarse crackles throughout the entire chest. Laboratory data showed leukocytosis and increase of CRP value. Adult respiratory distress syndrome (ARDS) was diagnosed based on progressive severe hypoxemia and bilateral diffuse alveolar shadows on chest X-ray film. The cause of ARDS was considered to be septicemia as staphylococcus aureus was cultured from lochia. The patient was intubated, then artificially ventilated employing PEEP. Chemotherapy using three different kinds of antibiotics was started, combined with the administration of corticosteroid and a protease inhibitor, Urinastatin. The patient finally recovered completely.
