Two problems are discussed: hospital infection of neonates and potentially fatal neonatal infections caused by group B streptococci and E. coli K1. The incidence of hospital acquired infections in a neonatal intensive care ward was 12.4%. Premature infants with an average weight of 1673 g were particularly prone to infection. On the average, infected patients stayed in hospital 34.8 days, uninfected patients 6.8 days. The most common infections were sepsis, skin infections, infections of the upper and lower airways and meningitis. Group B streptococci are among the most frequent pathogens of potentially fatal postnatal infections. The "early" form (usually sepsis) and "late" form (usually meningitis) are presented in detail.

Internal intrapartum fetal monitoring has been implicated as a source of maternal and fetal sepsis. We report water-borne contamination of a component of the intrauterine pressure transducer and suggest that this may be a potential source of nosocomial infection.

Utilizing a semiquantitative technique for culturing vascular catheters, we prospectively studied the risk and profile of infection caused by arterial catheters used for hemodynamic monitoring in 95 patients with a high risk of nosocomial infection. Of 130 catheters, 23 (18 per cent) produced local infection (larger than or equal to 15 colonies on semi-quantitative culture) and five septicemia (4 per cent). Sixteen of the 23 local infections and all septicemias occurred with catheter placements exceeding four days (p less than 0.001). Other factors associated with an increased risk of infection included insertion by surgical cut-down rather than percutaneously (ninefold increased rate of bacteremia, p = 0.008) and the presence of local inflammation (12-fold increase, p = 0.009). Systemic antimicrobial therapy (given to 80 per cent of the entire group and to four of the five with septicemia) did not protect against catheter-related infection but may account for the predominance of enterococci, Candida and gram-negative bacilli in these infections. Twelve per cent of all nosocomial bacteremias occurring in this critical care unit population originated from an arterial catheter. Indwelling arterial catheters pose a significant risk of bacteremic infection to ctirically ill patients. The percutaneous mode of placement is preferred; when prolonged arterial cannulation is required, the site should be rotated every four days. Local pain or inflammation, or clinical signs of sepsis without an obvious source should prompt removal and culture of the catheter.

The safety and efficacy of tobramycin and cephalothin in treatment of suspected sepsis were studied in neutropenic children with various malignancies. Twenty episodes of suspected sepsis in 19 febrile children with cancer were treated with parenteral tobramycin and cephalothin; the duration of therapy ranged from one to 80 days. In 14 of the 20 episodes of suspected sepsis, a favorable clinical response was achieved within five days after initiation of antibiotic therapy. These episodes included a urinary tract infection with Proteus mirabilis and sepsis due to Escherichia coli. In four of the additional six episodes, clinical deterioration was though to be caused by the underlying malignancies. Two episodes included a case of E. coli spesis that ended fatally and a nosocomial infection with Eikenella corrodens. Results of this study suggest that combination therapy with tobramycin and cephalothin is safe and efficacious in treatment of suspected sepsis in febrile children with malignancies and neutropenia.

The authors report a nosocomial infection outbreak by Klebsiella pneumoniae, observed in neonates at a gyneco-obstetrical hospital from Mexico City. Forty six newborns presented one or more infections due to K. pneumoniae during their stay in neonatal care units, between October 3 and November 12, 1988. Sepsis was documented in 41 cases by clinical picture and routine laboratory exams, including one positive, blood culture at least. The most frequent invasive procedures practiced in these patients were catheterization and ventilatory support. K. pneumoniae was isolated as well from several environmental sources that could have led to infection of patients. Treatment of cases was initiated with ampicillin-amikacin, however, therapeutic failure with a lethality rate of 50% (14/28) and results of antimicrobial susceptibility conducted to treatment with cefotaxime. Fifteen out of 19 patients receiving the cephalosporin survived. To prevent outbreaks like the one presented here, we concluded that appropriate measures dealing with hygiene and education of personnel plus monitoring of bacterial susceptibility to antimicrobials, should prove successful in our environment.

Although catheter-related sepsis (CRS) is an important cause of nosocomial infection and the major complication of intravenous catheter use, there is, as yet, no consensus concerning either a useful definition of CRS or the optimal method of catheter management and prevention of infection. Semiquantitative culture of catheter tips is a useful method of diagnosis of CRS but other techniques such as quantitative catheter blood cultures and Gram staining of the catheter have roles in selected patients. The most significant impact on the prevention of CRS is made by the introduction of an intravenous therapy team. The site and method of catheter insertion, type of dressing and antisepsis, catheter flushing and use of prophylactic antibiotics are also important issues. Techniques such as guide-wire exchange and catheters such as triple lumen and total implantable venous access devices have their own infection problems. Many new and interesting approaches to the prevention of CRS are being formulated. To facilitate further progress, a standardized definition for diagnosis, and revised recommendations for prevention of CRS would be helpful.

The neutropenia often seen in infants of hypertensive mothers (IHMs) at < 12 hours of age has been associated with nosocomial infection in the first 18 days of life. To assess maternal hypertension as an independent factor for nosocomial infection, we compared 101 low birth weight (< or = 2.00 kg) IHMs to a concurrent birth weight-matched group of infants of normotensive mothers (INMs). Infants without differential leukocyte counts at < 12 hours of age were excluded, leaving 93 IHMs and 98 INMs. The incidence of neutropenia at < 12 hours among IHMs was not significantly different from that among INMs (42/92 (45%) vs 37/98 (38%)). Nosocomial infection was more frequent in neutropenic IHMs than in neutropenic INMs (12/42 vs 2/37; p = 0.007). Infection in IHMs included omphalitis (2 infants), pneumonia (4), and sepsis with or without meningitis (6); INMs had cellulitis (1) and sepsis (1). The underlying mechanism(s) for this predisposition remains to be elucidated, although limited data suggest that neutropenia may be more severe and prolonged among IHMs.

To study the incidence and types of infection among severely traumatized children, we reviewed the medical charts of 212 children, hospitalized following traumatic injury, who received antibiotics at sometime during their hospitalization. Infection occurred in 19%. Eleven children had trauma-related infections, whereas 29 (71% of those infected) had 36 nosocomial infections. Tracheitis, sepsis, and urinary tract infections were the most common nosocomial infections and were diagnosed in the second week (10 +/- 3 days) following injury. Nosocomial infections were more likely to develop in children who were more severely injured and who had a greater number of invasive procedures. Severe head injury (cerebral edema or subarachnoid hemorrhage) was more common in those with nosocomial infection (P < .0002, odds ratio 6.8, 95% confidence interval 2.2 to 21.3). Those without these injuries were much less likely to develop nosocomial infections (specificity 97% and negative predictive value 86%). Finally, the development of any nosocomial infection prolonged the hospitalization by a mean of 16 +/- 6 days when comparing children with the same degree of traumatic injury. Prevention of nosocomial infection in children with severe trauma will significantly reduce length of hospitalization.

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.

MRSA strains were first isolated in 1981 and have increased markedly from 1985 in our surgical ward. One hundred and ninety four strains of MRSA were isolated and 81 cases developed critical infections which were associated with enterocolitis, pneumonia and sepsis. There were many cases in esophageal cancer patients. Bacteriological features of the MRSA strains clearly changed in 1985 from IV to II coagulase type, accompanied with high resistance for antibiotics. Our management against nosocomial infection for MRSA started from April 1988. The number of MRSA cases decreased in 1989, increased in 1990 and decreased again in 1991. We are confident that our management is effective and we will take further efforts to choose the most adequate antibiotics after surgery in our surgical ward.
