Daily prophylactic application of either 1.0% silver sulfadiazine cream or 0.1% gentamicin cream was compared for effectiveness in preventing bacterial colonization of burn wounds and sepsis. Pseudomonas aeruginosa colonized the wounds of 37% of the 38 patients treated with silver sulfadiazine and 30% of the 33 patients treated with gentamicin; gentamicin-resistant P. aeruginosa colonized the wounds of 21% of the patients treated with gentamicin. Staphylococcus aureus colonization occurred in 55% of the patients treated with silver sulfadiazine, whereas colonization with Candida species occurred in 58% of the patients treated with gentamicin. Although gentamicin-resistant organisms caused no deaths their repeated appearance resulted in discontinuation of prophylaxiz with gentamicin cream. The next year P. aeruginosa strains resistant to gentamicin were isolated from burn wounds of only two patients who had not previously received parenteral therapy with gentamicin or tobramycin. Gentamicin cream should be reserved for treating patients with wounds infected by gentamicin-sensitive P. aeruginosa and those allergic to sulfa drugs. For most patients with burn wounds silver sulfadiazine is safe and effective as an antibacterial agent for topical prophylaxis.

Gentamicin (GM) was intramuscularly injected to 16 children with various infectious disease (1 septicemia, 1 purulent meningitis, 4 bronchopneumonia, 1 pyothorax, 3 pyelonephritis, 2 acute cystitis and 4 RITTER'S dermatitis). The results obtained are as follows: 1. The excellent and good clinical results were noted in all patients except for an indeterminate case with bronchopneumonia because of the concomitant therapy with CEZ. The effective rate was 100.0%. This was possibly because of quite high susceptibility (See Article) of all isolates to gentamicin. 2. Doses of GM were adjusted depending on the style of infectious diseases. The satisfactory clinical results were obtained in some cases by increasing its recommended dosage to about 5-8 mg per kg per day. 3. No kidney dysfunction, liver dysfunction, the 8th cranial nerve damage, etc. were observed by administering 5 to 8 mg per kg per day for at maximum 18 days, in this clinical trial. 4. It has been indicated in this clinical trial that GM is worthy to be used as a first-choice drug in chemotherapy of infectious diseases caused by Staphylococcus, gram-negative bacillus, etc., especially in patients who are hypersensitive to penicillin and cephalosporin derivatives. However, further study would be required for the safety of increase in its dosage and duration of administration.

Gentamicin in combination with cephalothin (Gent-Ceph) or with chloramphenicol (Gent-Chloro) was utilized in the treatment of 55 infections occurring in 49 cancer patients. Responses were obtained in 78% of the infections treated with Gent-Ceph and in 64% of those treated with Gent-Chloro. Pneumonia and septicemia were the most common infections in this study. Among the cases of penumonia, 64% responded to Gent-Ceph and 67% to Gent-Chloro. Among the cases of septicemia, 88% responded to Gent-Ceph and 50% to Gent-Chloro. All of the identified organisms producing infection were gram-negative bacilli. Of these, E. coli was the most common. All organisms were resistant to cephalothin in vitro, and only 41% of them were resistant to chloramphenicol. However, resistant organisms responded significantly better to the Gent-Ceph combination (p less than 0.025). Also, response to therapy among patients with severe neutropenia (less than 100 neutrophils/mm3) was better for those patients treated with Gent-Ceph (p = 0.07). The combination of gentamicin with cephalothin or with chloramphenicol did not increase the frequency of side effects expected from gentamicin alone. No significant hematological toxicity was seen among those patients treated with chloramphenicol. Gentamicin in combination with cephalothin or chloramphenicol is an effective and safe antibiotic combination against gram-negative bacilli infections occurring in cancer patients. The efficacy of Gent-Ceph in patients with severe neutropenia is particularly advantageous.

We have presented recommendations for diagnosis and management of otitis media in children based on a comprehensive review of the pertinent medical literature. For an entity that is so common, there still remain amazingly large numbers of areas of controversy. We have also attempted to stress the importance of appropriate therapy and adequate followup as being very important in the management of otitis media. Newer concepts, particularly the use of the impedance bridge tympanogram, have been mentioned. With all the above background information in mind and with considerations for what is practical for the patient and the medical community, we would recommend the following as the acceptable minimal care for patients with otitis media. When the diagnosis of the acute otitis media is made on the basis of physical findings of myringitis, and/or middle ear fluid, and/or rupture of the tympanic membrane, the following treatment course is advisable: Neonates Culture of middle ear fluid if possible. Ampicillin 200 mg/kg/day intramuscularly. Gentamicin 3/5mg/kg/day intramuscularly. Hospitalize and treat until well and for minimum of seven days. Observe closely for meningitis and other infections and drug toxicity. These should be handled only by physicians experienced in dealing with patients in this age range. Appropriate work-up for septicemia should precede treatment. Switch to specific antibiotic when cultures and sensitivity available. Children. From 2 months to 6 years of age: Ampicillin 50mg/kg/day. Decongestant (if desired). Administer for ten days. Every patient with otorrhea, severe otitis and those not clinically well should be seen for followup ten to 14 days later. They should have a minimum of otologic evaluation including drum mobility. In persistent cases, audiometry and otologic referral are necessary. If patient is allergic to penicillin, erythromycin at 20mg/lb/day may be used. Trimethoprim sulfa may hold promise in the future. Tetracycline is never indicated in this age range because of side effects and high relapse rate secondary to resistant organisms. Patients above 6 years of age: Penicillin pheyoxymethyl 250 mg every six hours for ten days. Decongestant (if desired). Followup and penicillin allergy as above.

Most infections on the surgical ward are due to one or more gram-negative rods, acting either as the sole pathogens or as principal components in a polymicrobial flora. To date, parenteral aminoglycosides have proven to be the most effective antibiotics for control or treatment of such sepsis. Unfortunately, however, serious complications as well as therapeutic failures do occur. During a 40-month period, 405 surgical patients receiving aminoglycosides (Gentamicin, Tobramycin, Sisomicin, or Amikacin) were prospectively studied with respect to: indications for antibiotic; patient population; serum concentrations of antibiotic according to route of administration, dose in mg/kg/day, and renal function; rapidity of antibiotic excretion in the urine; causative bacteria and their sensitivities to each aminoglycoside as determined by both disc and tube dilution methods; severity and frequency of drug complications; and clinical efficacy of each study antibiotic. Results supported the contention of a superior effectiveness from aminoglycosides for established abdominal and unspecified surgical infections, more rapid development of therapeutic blood levels by intravenous administration, need to alter drug dose according to frequent serum creatinine determinations, increased drug toxicity in dehydrated and shocked patients, preventability of complicating Candida sepsis, and the importance of early as well as adequate surgical debridement and drainage.

The minimal inhibitory concentrations of gentamicin and minocycline alone and in combination were determined by a broth microdilution method for 100 aerobic, facultative, and anaerobic isolates representative of pathogens recovered from patients with intra-abdominal sepsis. Gentamicin inhibited all strains of Klebsiella, Enterobacter, and Pseudomonas aeruginosa in concentrations of 0.4 to 3.1 mug/ml and all strains of Escherichia coli and Proteus mirabilis in concentrations of 0.8 to 12.5 mug/ml. Whereas minocycline did not consistently inhibit these organisms in concentrations of 1.6 mug or less/ml, it did act synergistically with gentamicin against 43% of the Enterobacteriaceae tested in clinically achievable concentrations; significant synergy was most common with E. coli (60%). Minocycline inhibited 62% of Bacteroides fragilis, 71% of Clostridium, 40% of anaerobic cocci, and 40% of enterococci tested in concentrations of 1.6 mug or less/ml. Whereas gentamicin rarely inhibited these organisms in concentrations of 6.2 mug or less/ml, it did act synergistically with minocycline against 20% of B. fragilis, 67% of Clostridium, 22% of anaerobic cocci, and 22% of enterococci (which had minimal inhibitory concentrations of minocycline within the range tested) at clinically achievable concentrations. Although only four (13%) of the 30 isolates resistant to both gentamicin and minocycline alone were inhibited by clinically achievable concentrations of the combination, the observed synergy, particularly against strains of E. coli, was considered to be of potential clinical usefulness. Antagonism between gentamicin and minocycline was not observed at the concentrations tested.

We report a case of Yersinia enterocolitica septicemia with septic arthritis. Gentamicin administration controlled the septicemia but failed to eradicate the organisms in the joint, in spite of a synovial fluid level four times its minimal inhibitory concentration after four days of therapy. Development of azotemia necessitated change of antibiotic therapy to chloramphenicol, which eradicated the infection. While Y enterocolitica infection in the United States is uncommon, it must be added to the list of organisms causing suppurative arthritis and septicemia in susceptible hosts. Septic arthritis must be distinguished from the much more common reactive theumatic polyarthritis associated with Y enterocolimica infection, for which antibiotic therapy is neither needed nor helpful.

Mortality from neonatal meningitis due to gram-negative microorganisms remains 50% despite use of aminoglycoside antibiotics. Blood was obtained on 238 occasions from 77 neonates with putative or documented sepsis; paired blood and cerebrospinal fluid (CSF) samples were obtained on 14 occasions from ten neonates with meningitis. Kanamycin and gentamicin were measured by a radioisotopic assay procedure. Kanamycin was administered at 15 mg/kg/day in three divided doses intravenously; serum concentrations peaked at one hour (mean, 7.77mug/ml). Gentamicin was administered at 7.5 mg/kg/day in three divided doses intravenously; serum concentrations peaked at two hours (mean, 5.34mug/ml). Both aminoglycosides generally were nondetectable within the CSF; survival of neonates with gram-negative meningitis correlated specifically with the sensitivity of their isolates to ampicillin which was administered concurrently. This study suggests that alternative approaches to the treatment of neonatal sepsis should be explored; administration of an antibiotic which crosses the blood-cerebrospinal fluid barrier more readily should be considered.

From 1969 to 1974, 19 cases of Serratia marcescens endocarditis were observed in the San Francisco Bay Area. Seventeen patients were intravenous drug users, and Serratia caused 14% of all addict-associated endocarditis in San Francisco. Serratia strains were nonpigmented and had typical antibiotic sensitivities, except that 9 of the isolates exhibited colonial variation, with each variant having different antibiotic sensitivities. Aortic or mitral valves were involved in 13 patients, and heart failure developed in 9 of these. Twelve patients had embolic episodes to brain, iliofemoral arteries, or lung. Five of 6 patients with tricuspid valvulitis were cured by antibiotics either with (1) or without excision of the valve. All 12 patients with aortic or mitral valvulitis treated medically died; 11 had unremitting sepsis. Aortic valve replacement and antibiotics were effective in 1. Gentamicin combined with either carbenicillin or chloramphenicol was the most effective treatment regimen.

Polymicrobial infection is a significant cause of mortality in critically ill patients. Antibiotics and surgical intervention are useful but limited in their effectiveness for combating mixed infections. New prophylactic and therapeutic approaches are required to improve survival in critically ill patients. Neutrophils are a known primary host defense mechanism against bacterial infection. We evaluated the use of a neutrophil growth factor, recombinant human granulocyte colony-stimulating factor (G-CSF), to improve survival in a well-established sepsis model, cecal ligation and puncture (CLP). When administered beginning 4 days before CLP with injections continuing for 14 days after CLP, mice that received 10, 100, or 1000 ng of G-CSF had significantly improved survival compared with the control group. When treatment began at the time of CLP and continued for 7 days after CLP, G-CSF treatment resulted in a dose-dependent improvement in survival in groups that received 100, 500, or 1000 ng. The interaction of G-CSF and conventional antimicrobial therapy was evaluated by administration of G-CSF plus gentamicin. Mice received 100 ng of G-CSF beginning on day 1 before CLP with injections continuing for 3 days after CLP. Gentamicin-treated mice received a single 15 mg/kg injection of gentamicin at the time of CLP. Mice that received G-CSF alone or gentamicin alone had significantly improved survival compared with controls. Mice that received G-CSF plus gentamicin had improved survival compared with control mice and compared with mice that received G-CSF alone but not compared with mice that received gentamicin alone.(ABSTRACT TRUNCATED AT 250 WORDS)
