A strain of Methicillin-Resistant Staphylococcus aureus (MRSA) was first isolated in our hospital in March 1986. Since then, MRSA has become a difficult pathogen and a cause of sepsis, bacterial endocarditis, and pneumonia in 1988. Rigorous hospital-wide control measures have been planned. The major control measures, based on the various investigations reported, consist of the following three points; improvement of environmental control, reinforcement of handwashing practices during care and control usage of antibiotics. The frequency of isolation of MRSA among the S. aureus isolates was 43.3% in 1988 and this was further reduced to 31.7% in 1990. The total number of MRSA isolates from decubitus, bile, and blood samples have also declined. This decline resulted in a reduction of cases of severe MRSA infection. As yet, MRSA strain are still isolated on incubation. There may be a limit to complete control by measures in a single hospital. It is desired that regional measures and national consensus on nosocomial infection be established.

Staphylococcus aureus (SA) is among the most important causes of skin infections. The incidence of Methicillin-resistant SA (MRSA) strains isolated from skin and skin structure infections was about 20-40%. In deep-seated pyoderma such as furuncle and furunculosis, MRSA was more frequently isolated than in other type of infectious diseases of the skin. But the incidence was gradually increasing. As to coagulase typing, type IV was most frequently isolated in MRSA. The damaged skin is easily colonized by high numbers of SA on its surface and within hair follicles. Through the indwelling catheters or decubitus SA on the skin could cause easily severe systemic MRSA infections such as sepsis or endocarditis of in-patients.

Panipenem/betamipron (PAPM/BP) is a mixture of panipenem (PAPM), carbapenem antibiotic, and betamipron (BP), N-benzoyl-beta-alanine. The adverse reaction to PAPM of the kidney is reduced by the addition of BP to PAPM which inhibits the anion transport in the kidney tubules. We studied the pharmacokinetics and the clinical efficacies of PAPM/BP in children and we evaluated the antibacterial activities of PAPM by determining MIC values of PAPM in vitro against organisms isolated in our children's hospital from January to December, 1990. 1. Pharmacokinetics 10 mg/kg of PAPM/BP (10 mg PAPM/10 mg BP) was administered intravenously by drip infusion to 7 children. The mean blood concentration of PAPM was 14.8 micrograms/ml at the peak, and the mean half life was 0.9 hours in blood. PAPM was not detected in blood 3 hours after the time when the peak values were attained. 2. Clinical studies 10 mg/kg of PAPM/BP was administered intravenously 3 times a day to 18 cases including 15 of respiratory infections, 2 of otitis media and 1 of sepsis. The clinical efficacies of PAPM/BP were excellent or good in 17 out of the 18 cases. All causative organisms isolated in 5 cases, Methicillin-sensitive Staphylococcus aureus (MSSA) (1 case), Streptococcus pneumoniae (1), Haemophilus influenzae (2) and Branhamella catarrhalis (1) were eradicated in a few days upon the administrations of PAPM/BP. No adverse reactions due to PAPM/BP were observed, but a slight elevation of platelet counts in blood was observed in 1 case, which was normalized soon after the end of the treatment. 3.

Imipenem/cilastatin (IPM/CS) was used to treat 39 documented infections in patients who had failed to respond to other antibiotic regimens. The overall response rating was 76.9%. Respiratory infections responded less frequently (efficacy rating, 55.6%) to IPM/CS than abdominal infections, urinary tract infections, or sepsis. Methicillin-resistant Staphylococcus aureus, Xanthomonas maltophilia, and Acinetobacter calcoaceticus were less sensitive to IPM/CS therapy than the other bacterial strains encountered. Respiratory tract infections were though to be less responsive to IPM/CS, probably because imipenem-resistant strains of S aureus were present in most of those cases. It is concluded that IPM/CS is well tolerated and effective in the treatment of various bacterial infections.

The microorganisms isolated in 1981-1985 from 171 cases of septicemia in patients with hematological malignancies were on the whole the same as those found in 1970-1972. The distribution between species was also quite similar for the two periods except within staphylococci, where the isolation rate of coagulase-negative staphylococci was higher in the latter period while that of Staphylococcus aureus was lower. Of 67 strains of Enterobacteriaceae tested for an aminoglycoside, 6% were found to be resistant, whereas 8% of 48 Enterobacteriaceae strains were found to be cefotaxime resistant. Methicillin- or aminoglycoside resistant S. aureus did not occur.

A 10-year survey of positive blood cultures was conducted among 6,616 infants admitted to an intensive care unit from 1974-1983. Group B streptococci (59) and E. coli (32) were the most common pathogenic organisms isolated from the early onset group (less than 72 hours of age). The percentage of infants with bacteremia, the birth weight distribution of infected infants, and the organisms isolated did not change in the early onset group throughout the study period. Coagulase negative staphylococci (471), S. aureus (126), E. coli (33), Klebsiella sp. (30), and enterococci (30) were the most frequent organisms isolated from the late onset group. The frequency of infection in the late onset group did not change as a function of time but was associated with decreasing birth weight during the study period. Methicillin and gentamicin resistance among coagulase negative staphylococci preceded that of S. aureus by one to three years, suggesting interspecies transfer of bacterial resistance among staphylococci. The data indicate that whereas the epidemiology of early-onset septicemia has remained relatively stable during the study period, the incidence of late onset bacteremia is increasing with improved survival rates of low birth weight infants. Antibiotic administration in the late onset group should include consideration of hospital-acquired, multiply antibiotic resistant organisms as well as maternally-acquired bacterial flora.

The experience with septicemia due to coagulase-negative Staphylococcus at a 623-bed primary care hospital between 1980 and 1984 was reviewed. A total of 38 episodes in 37 patients were documented; data were available on 37 episodes in 36 patients. The organism accounted for 3.8% of all cases of septicemia and 6.7% of cases of nosocomial septicemia and was associated with 0.03% of all admissions. The incidence remained stable over the 5 years. The rate of survival 28 days after the episode was 78%. Most of the episodes (31) originated from infected vascular access sites. Of the 37 isolates 15 (41%), all S. epidermidis, were slime producing. S. epidermidis accounted for 33 of the isolates; of the 33, 5 were methicillin-resistant and slime producing. Various in-vitro susceptibility testing methods and testing for beta-lactamase production yielded conflicting results. Methicillin resistance, slime production and speciation as S. epidermidis were not confirmed as virulence markers. Five patients with methicillin-resistant organisms were treated with cephalosporins, and all recovered. These findings as well as examination of the literature do not support the recommendations that laboratories report such isolates as resistant to all beta-lactam agents and that vancomycin be given in all such infections. The different case mix in community hospitals as compared with university centres results in different patterns of nosocomial infection. Since the community hospital patient population is much larger, more information on the patterns of infections in these centres is needed.

The work describes an epidemic infection by Methicillin-Resistant S. aureus in a N.I.C.U. which took place during the first six months of 1986. Hospital systemic infection supported by M.R.S.A. are frequently noticed in N.I.C.U. This is related, on the one side with a selection of antibiotic resistant bacterial strains inside the hospital premises and, on the other side with increased survival of high infectious risk neonates who are subjected to invasive medical manoeuvres. The cases reported include 7 neonates (5 of which were preterms) who were affected by a severe sepsis. From an epidemiological study it appeared that M.R.S.A. strain was introduced in N.I.C.U. by a neonate coming from the surgery after being operated for a diaphragmatic hernia. The isolation and the treatment of the carriers, the severe asepsis and the systematic disinfection of the Unit made it possible to eradicate the infectious strain. The infected neonates have been treated with an aimed antibiotic therapy, especially with Vancomycin, administration of blood and/or fresh plasma and/or immunoglobulins and/or concentrated granulocytes. The outcome was favourable for 3 neonates; of the others, 1 showed post-infectious neurological sequelae and 3 died (they were however affected by other severe associated diseases).

Eleven hundred and sixty eight traumatic cases have been operated on under constant conditions in a conventional operating room with filtered air and positive pressure using absolute filters of 99.999 efficiency. Two hundred and five were submitted to post-operative prophylactic administration of Cephalosporin (Cefazolin) for 2 days. The overall results showed 0.6 p. 100 of infection but 4 cases of severe sepsis were seen in the group of patients who had received prophylactic antibiotics. The authors have compared these results with those obtained during the previous period when the operating room was less modern. They conclude that this factor is of paramount importance. On the other hand, they have observed 2.1 p. 100 of contaminated drains without subsequent infection. They are concerned at the increase of gram-negative organisms resistant to Cefazolin (60 p. 100) and of Staphylococci resistant to Methicillin (30 p. 100). They conclude that the peroperative flash technique of the administration of Penicillin M is worthwhile.
