Owing the frequent occurrence of intrahepatic stones in orientals, cholangitis presents a real problem. Surgery and antimicrobial drug therapy are the main forms of treatment. A retrospective study of choledochotomy, including biliary tract surgery, performed between July 1987 and June 1990, was conducted. Cases with negative common duct exploration during cholecystectomy were excluded. Among 186 cases, 128 (68%) had positive bile growth, which was defined as cholangitis. Sepsis-related complications occurred in 51 patients (27.4%), including 3 surgical deaths, 30 wound infections, and 18 others. The complication rate was higher in the cholangitis group than in the negative group (37.5% vs. 5.2%). However, if peri-operative antibiotics were effective against the cultured bacteria species, the complication rate was 16.9%; if not, the complication rate was 85.3%. For the different-generation cephalosporins used in the peri-operative period, the complication rates were 32.2%, 20.8%, and 27.6% each for 1st, 2nd, and 3rd generation cephalosporins, with no statistically significant differences. In microbiological study, polymicrobial infection was the rule. On average, 2.3 species were grown from each specimen. Enterococcus proved the most important species with a 54% culture rate. E. coli and Pseudomonas were important gram-negative bacilli, with culture rates of 46.1% and 39.1%, respectively. Anaerobic species were cultured in 12.3% of the patients. For good coverage of cholangitis prior to operation, the proper antibiotic should have potency against gram-positive Enterococcus, gram-negative bacilli, especially Pseudomonas and E. coli, and anaerobic species, especially Bacteroides.

Eighteen immuno-compromised children (malignancies, hematological diseases, collagen diseases) with neutropenia and infections were treated with imipenem/cilastatin sodium (IPM/CS), and the efficacy and the safety of the drug were evaluated. 1. Responses to IPM/CS were excellent in 13 patients, good in 1, and fair in 4. None of the patients displayed a poor response to the treatment thus the efficacy rate was 77.8%. 2. Of 5 patients with sepsis, 4 had excellent or good responses. IPM/CS was effective against sepsis caused by Enterococcus faecalis and Pseudomonas aeruginosa. 3. In patients with severe neutropenia (WBC less than 100/mm3), the efficacy rate was 70%. 4. As for side effects, elevations of GOT and GPT were observed in 1 patient with liver cirrhosis. These results indicate that IPM/CS is safe and effective in immuno-compromised children with neutropenia and infections.

Pseudomonas aeruginosa remains a cause of serious wound infection and mortality in burn patients. By means of restriction fragment length polymorphism analysis and a DNA probe for the pilin gene of Pseudomonas, a lethal strain of nosocomial P. aeruginosa was identified as the cause of an outbreak of wound infections among burn patients. Environmental surveys suggested an association of the outbreak with hydrotherapy provided to many patients in a common facility. In a trial of burn wound care without hydrotherapy, overall mortality was reduced significantly, mortality associated with pseudomonas sepsis was eliminated, and the strain of P. aeruginosa associated with earlier mortality was eradicated. Moreover, fewer nosocomial pseudomonas infections, lower levels of pseudomonas resistance to aminoglycoside antibiotics, significantly fewer pseudomonas infections of skin graft donor sites, and later appearance of Pseodomonas species in burn patients were found during the period when hydrotherapy was not used.

The diagnosis of central venous catheter-related sepsis depends on a positive culture obtained from the distal intravascular portion of the catheter. The effects of the subcutaneous tunnel and the skin exit site on the accuracy of cultures obtained from the catheter are unknown. We have developed an in vitro model to study the effect of these variables. By inoculating polyethylene catheters embedded in agar with Pseudomonas aeruginosa, we were able to show that: (1) capillary action occurs along catheters in an agar tunnel, (2) organisms that are growing on the distal segment (tip) of the catheter can be dislodged from the surface of the catheter when it is pulled through the agar tunnel, and (3) pulling a catheter through a contaminated area results in distal contamination.

We made an investigation on central venous catheter related sepsis (CRS) in recent 5 years (1987-1991). The incidence of CRS was high; 16.0% (125 out of 782 cases) or 13.1% (135 out of 1029 catheters). CRS occurred frequently during 2-3 weeks after catheter insertion. The incidence of CRS was not affected by the kind of disease (malignant or benign), complication (diabetes, liver cirrhosis, collagen disease) operation or administration of antibiotics. Eight percent out of 91 organisms isolated from culture of catheter tips were so-called resistant strains; multi-drug resistant Staphylococci (16), Pseudomonas aeruginosa (5), fungi (49), etc. Complications (shock, acute renal failure, secondary pneumonia, fungal endophthalmitis) broken out in 18 patients (14.4% out of 125 CRS). Fungi were isolated from 14 out of 18 complicated cases, furthermore fungi were isolated alone in 11 cases. No complication were seen among cases from which gram positive cocci were isolated alone. Body temperature and white blood cell count of complicated cases were significantly higher than those of uncomplicated cases. The duration until removal of catheter from outbreak of fever in complicated cases was significantly longer than that in uncomplicated cases.

From January 1984 to April 1987, we have prospectively studied 210 consecutive episodes of bacteremia recorded in patients who underwent major surgical procedures. The incidence rate was 6.4 episodes/1000 surgical procedures. Men were responsible of 73.8% of episodes. The highest incidence was recorded in general surgery patients and the lowest in Ob & Gyn patients. Bacteremia-related mortality was 15.2% (overall mortality 29.5%). The five most common microorganisms isolated were: Staphylococcus epidermidis (17.7%), Staphylococcus aureus (14.7%), polymicrobial flora (13.3%), Escherichia coli (11.4%) and Pseudomonas sp. (9.5%). The common sources of bacteremia were intravascular devices (34.7%), surgical wound infection (28.5%) and urinary tract infection (12.8%). Multivariant analysis identified six variables that influence an adverse prognosis: complications, source of sepsis in a joint or unknown, admission in trauma or vascular surgery department, development of sepsis between the second and eight postoperative day, chronic illness or fatal underlying disease and sepsis after clean surgical procedures.

The synthesis of large numbers of antibiotics over the past three decades has caused complacency about the threat of bacterial resistance. Bacteria have become resistant to antimicrobial agents as a result of chromosomal changes or the exchange of the exchange of genetic material via plasmids and transposons. Streptococcus pneumoniae, Streptococcus pyogenes, and staphylococci, organisms that cause respiratory and cutaneous infections, and members of the Enterobacteriaceae and Pseudomonas families, organisms that cause diarrhea, urinary infection, and sepsis, are now resistant to virtually all of the older antibiotics. The extensive use of antibiotics in the community and hospitals has fueled this crisis. Mechanisms such as antibiotic control programs, better hygiene, and synthesis of agents with improved antimicrobial activity need to be adopted in order to limit bacterial resistance.

Pharmacokinetic, bacteriological and clinical studies were performed on panipenem/betamipron (PAPM/BP) in children. The results are summarized as follow: 1. Twelve patients with various bacterial infectious diseases were treated with PAPM/BP. Each dose was 20 mg/20 mg/kg, administered 3 times daily, in 30-minute intravenous drip infusion. Treatments were continued for 5-22 days. Clinical efficacies of PAPM/BP in 12 patients with bacterial infections (1 with suspected sepsis, 5 with pneumonia, 1 with acute maxillary sinusitis, 2 with acute otitis media, 1 with cervical abscess and 2 with urinary tract infection complexed type) were evaluated as excellent in 7, good in 4 and fair in 1, with an efficacy rate of 91.7%. Seventeen causative organisms found in 10 patients (Haemophilus influenzae in 4, Branhamella catarrhalis in 3, Streptococcus pneumoniae in 2, Pseudomonas aeruginosa in 2, Staphylococcus aureus in 1, alpha-Streptococcus in 1, Corynebacterium sp. in 1, Peptostreptococcus micros in 1 and Klebsiella pneumoniae in 2) were eradicated except 2 strains (S. aureus and P. aeruginosa) from 1 patient (patient No. 2). No adverse reactions were observed in any of the 12 patients. 2. MICs of PAPM were examined against 22 clinical isolates (H. influenzae 5, B. catarrhalis 3, alpha-Streptococcus 3, S. pneumoniae 2, Corynebacterium sp. 2, S. aureus 1, P. aeruginosa 1, P. micros 1, Enterobacter cloacae 1, Escherichia coli 1, Group D Streptococcus 1 and Staphylococcus epidermidis 1) from children with bacterial infections. PAPM showed a good antibacterial activity comparable to the activity of cefoperazone (CPZ) against S. pneumoniae strains relatively tolerant to penicillins. However, the activity of PAPM against H. influenzae was somewhat weaker than that of CPZ. 3. Pharmacokinetic studies.(ABSTRACT TRUNCATED AT 250 WORDS)

Management of infected prosthetic arterial grafts has traditionally included total graft excision especially when gram-negative bacteria were cultured. Between 1973 and 1991 we treated 42 patients with infected prosthetic grafts (33 polytetrafluoroethylene (PTFE), 9 Dacron) by complete graft preservation when the graft was patent, the anastomoses were intact, and the patient did not have sepsis. The infection involved the anastomosis (36 cases) or the body (6 cases) of 33 peripheral grafts and the distal segment of five aortofemoral and four iliac-distal grafts. Cultures of the 42 infected grafts grew gram-positive bacteria in 33 cases and gram-negative bacteria in 22 cases. Treatment adjuncts included repeated, radical operative wound debridement and rarely (7 of 42) rotational muscle flaps. This management resulted in a 10% (4 of 42) hospital mortality rate and an amputation rate in survivors of 3% (1 of 38 threatened limbs). All four deaths were due to sepsis: gram-positive bacteria were cultured in all cases and gram-negative bacteria in two cases. Of the 38 survivors, 29 (76%) wounds healed and remained healed after average follow-up of 3 years (range, 1 to 18 years). Nine other patients required total graft excision for nonhealing wounds (7 cases) or delayed anastomotic hemorrhage (2 cases). Gram-negative bacteria were cultured in four, and gram-positive bacteria were cultured in six of these nine wounds. Four of nine (44%) graft infections that cultured Pseudomonas organisms healed without complications versus 23 of 33 (70%) wounds that cultured gram-positive bacteria, and 12 of 13 (92%) wounds that cultured gram-negative bacteria other than Pseudomonas organisms.(ABSTRACT TRUNCATED AT 250 WORDS)

A review of the literature reveals that of the eight reported cases of patients with acquired immunodeficiency syndrome acquiring Norwegian scabies, three of these have been complicated by sepsis. We describe such a patient who contracted sepsis from Pseudomonas aeruginosa. We propose that the fissures often seen in severe cases of Norwegian scabies may serve as a port of entry for bacteria, thus placing these patients at a high risk for sepsis. We also believe that empiric antibiotic treatment is justified in these patients and that the choice of agent should be based on the institution's bacterial flora profile.
