The study evaluates the incidence and consequences of infectious complications after 700 transurethral resections of the prostate. The patients were treated individually for bacteriuria according to urine cultures. No general antibacterial prophylaxis was used. 376 patients (54%) had negative urine cultures throughout the course and received no antibacterials. Of the 256 patients with an indwelling catheter before surgery only 64 (25%) had negative cultures throughout, as opposed to 312 (70%) out of 444 patients without an indwelling catheter preoperatively. Antibacterial treatment was given to 127 patients (18%) before surgery because of bacteriuria. Positive urine cultures postoperatively indicated antibacterial therapy to 197 patients (28%). Four non-fatal cases of septicemia were recorded. The influence of bacteriuria and indwelling catheters on the postoperative course and on the length of hospital stay is documented. It is concluded that antibiotic prophylaxis may be indicated in patients with a preoperative urethral catheter; other patients should be treated if and when bacteriuria occurs.

Certain infections, such as UTI, may have an increased incidence during pregnancy owing to physiological changes. Between 2 and 10% of pregnant women have covert or asymptomatic bacteriuria which is associated with an increased incidence of acute symptomatic UTI in later pregnancy if left untreated. Thus antenatal screening to detect the presence of bacteriuria is justified. Most women will remain abacteriuric throughout the remainder of pregnancy after a single course of antibiotic therapy but a small percentage will fail to respond or have recurrent UTIs. Maternal infection with certain organisms, namely those which resist phagocytosis, may result in transplacental infection of the fetus in utero. Congenital syphilis is preventable and antenatal serological screening is usually routinely performed. Listeriosis following maternal infection in pregnancy is less predictable and the epidemiology of L. monocytogenes remains unclear. Genital tract carriage of sexually transmitted organisms, such as N. gonorrhoeae or C. trachomatis, may also be detected during pregnancy and antibiotic therapy will be indicated to eradicate such organisms and prevent maternal and neonatal morbidity. Antibiotic therapy during pregnancy will not, however, eradicate carriage of GBS from the genital tract, although carriage status at term can now be reliably predicted by using enriched culture techniques and swabbing multiple sites on more than one occasion. Where carriage is confirmed, the administration of intrapartum antibiotics to the mother appears a useful approach in the prevention of early onset neonatal GBS disease. Broad spectrum intrapartum antibiotics may also be indicated when there are complications, such as prolonged labour or premature rupture of membranes, which are associated with a higher incidence of maternal postpartum endometritis and morbidity than in women following uncomplicated vaginal delivery. Serious postnatal sepsis and shock is fortunately now rare. The pharmacokinetics of antibiotics in late pregnancy and the puerperium are altered and maternal serum levels may be reduced by 10-50%. Most antibiotics cross the placenta and are excreted in breast milk. Some agents, such as the beta-lactams, are considered safe in pregnancy and breast-feeding women while other antibiotics are contraindicated owing to risk of toxicity (often rare) or teratogenicity (often theoretical). Caution is necessary with many agents which may cause side effects or toxicity although this does not necessarily contraindicate their use in pregnancy.(ABSTRACT TRUNCATED AT 400 WORDS)

Catheter-associated urinary tract infections are the most common nosocomial infection and a frequent cause of significant morbidity, sepsis, and death. The pathogenesis is multifaceted. Most frequently, bacteria from the urethral meatus ascend to the bladder between the mucosal and catheter surfaces. Alternatively, bacteria may ascend within the drainage system following contamination of the drainage bag or disruption of the catheter tubing junction. The incidence of infection is approximately 5 to 7 per cent for each day of catheterization and closely linked to unalterable host factors such as age, female sex, and debilitating disease. Efforts to reduce the incidence of infection must begin with reduction of the frequency and duration of catheterization. Aseptic insertion of the catheter and careful maintenance of the drainage system are mandatory to prevent incidental bacterial contamination. Prophylactic, systemic, or topical antimicrobial agents and modifications of the catheter drainage system that are designed to reduce contamination are expensive and have not been shown to be efficacious for the majority of patients. Furthermore, antimicrobial prophylaxis frequently leads to outgrowth of resistant bacterial strains that are difficult to eradicate. However, antimicrobial prophylaxis warrants consideration for high-risk patients who are catheterized for a short time. If bacteriuria occurs prior to removal of the catheter, the patient should be treated with appropriate antimicrobial therapy. Urinalysis or urine cultures should be obtained following removal of the catheter to assure sterility of the urinary tract. If these guidelines are followed, the incidence and sequelae of catheter-associated urinary tract infections can be reduced.

We report the result of the bacteriological samples performed for 5 years (1980-1984) in neonates, referred to the neonate unit of the hospital of Clermont-Ferrand, for infection (2,894 infants). The CSF tests show aseptic meningitis in 4% of the cases and in 0.4% meningitis with bacteria on the direct examination and in culture. We emphasize the interest of carrying out the soluble bacterial antigen assay (Strepto B, Coli K1) to find out the bacteria involved in the meningitis. 13.7% of the infants have one or several positive blood culture. The germ is a E. Coli in 30% of the cases, and less frequently a streptococcus D. They are few listeria. In 1984, the frequency of streptococcus B is increasing. Septicemia due to anaerobic germs or Candida Albicans emerge during the stay in the unit. Among 12,704 bacteriological urine analysis, we compare the real urinary infections (in which the enterobacteria are the main strain: 75.3%) and the significant bacteriuria.

In a randomized control study comprising 261 patients undergoing transurethral prostatic resection (TUR), the effect of a short perioperative course with the oral combination of pivampicillin/pivmecillinam (PAPM) was analysed in 129 patients. The study was divided in 2 parts: the first 60 patients received 450 mg and the following 69 patients, 900 mg every 12 h until removal of catheter but not longer than for 1 week. 132 controls received parenterally 1 g of cefotaxime (CFT) daily throughout the study. During the first part of the study the frequency of bacteriuria in the PAPM group was 43% preoperatively and 30% 10 days postoperatively, during the second part 47% and 12%, respectively (p less than 0.025). In the CFT group the frequency of bacteriuria was reduced from 52% preoperatively to 28% postoperatively. The prophylactic effect (i.e. the protection against acquired bacteriuria) was 96% and 92% in the PAPM and the CFT groups, respectively. Preoperative bacteriuria was eliminated in 40% of the patients during first part and 69% during second part in the PAPM group, while corresponding figures were 48% and 46% in the cefotaxime group. There were 2 cases of septicemia and 5 of upper urinary tract infections throughout the study evenly distributed between the two groups. Oral pivampicillin/pivmecillinam 900 mg every 12 h was found to be a good alternative for perioperative antibiotic prophylaxis at TUR.

During a 6-month period data were collected on 460 patients residing on the long-term care division of this 1200-bed county hospital. The purpose was to determine prevalence and spectrum and to identify risk factors for skin infections, urinary tract infections, respiratory infections, and sepsis. Overall, the prevalence of nosocomial infections among 460 patients was 12%. Patients with infections had an average of 2.8 diagnoses of their underlying disease compared to patients without infections, who only had 1.8 diagnoses. Specific risk factors were identified. Skin infections were more common in patients who were nonambulatory, diabetic, malnourished, and incontinent of urine and feces, whereas respiratory infections were more common in patients who were smokers or had chronic obstructive lung disease and had not received pneumococcal vaccine. Thirteen percent of patients with an indwelling urinary catheter had symptomatic urinary tract infections, whereas 100% had asymptomatic bacteriuria.

This study evaluates the importance of low-colony-count bacteriuria (less than 10(5) CFU/mL) in septicemia originating from urinary tract infections. In a 14-month period, 260 episodes of septicemia occurred. No clinical or microbiologic evidence for a source other than the urinary tract was evident in 68 (26.2%) cases. Of these 68 patients, 13 (19.1%) had colony counts less than 10(5) CFU/mL, and 6 of the 13 had colony counts less than 10(4) CFU/mL. Nine of the infections were community acquired and four were nosocomial. None of the nosocomial cases were associated with an indwelling catheter; four of the 13 patients were receiving chemotherapy and/or steroid therapy. These data support the thesis that some cases of septicemia in patients other than acutely dysuric women, can be caused by UTIs with low colony counts.

This is a report of a randomized, comparative, double-blind study of mezlocillin and cefotaxime given perioperatively to 100 patients undergoing genitourinary surgery. Of 94 evaluable patients, 2 (4.7%) in the mezlocillin group and 2 (3.9%) in the cefotaxime group infections developed in the immediate postoperative period. The difference in these incidences is not statistically significant. One patient with recent bacterial prostatitis and prostatic calculi received cefotaxime and bacteriuria and sepsis developed on the first postoperative day.

Urinary tract infections (UTI) due to gram-positive bacteria are fairly uncommon. In order to investigate the efficacy of treatment for UTI secondary to gram-positive rods, we performed a non-comparative study on the effect of cefotaxime in 64 patients with gram-positive UTI. Patients with a history of hypersensitivity to cephalosporins and penicillin as well as patients who had received antibiotic treatment within 48 hours after the administration of cefotaxime, patients with hepatic disease and patients with fatal progressive disease were excluded from the study. UTI was confirmed by positive cultures with a colony count of greater than or equal to 100,000 cfu/ml of gram-positive organisms before treatment with cefotaxime. When sepsis or bacteriuria occurred after two days of hospitalization, the UTI was considered nosocomial. The most common microorganism isolated was Staphylococcus aureus, followed by Streptococcus faecalis. 30% of the patients showed polymicrobic bacteriuria, especially in association with gram-negative bacteria (70%). A high frequency of predisposing factors was present in the urinary tract, mainly obstruction, indwelling catheters, surgery and chronic debilitating diseases. Seven patients developed bacteremia. All patients were treated with cefotaxime i.m. or i.v. at a daily dosage ranging between 4 and 12 g. Urine cultures were repeated five days after the beginning of treatment and again two to three weeks after the end.(ABSTRACT TRUNCATED AT 250 WORDS)

The identity and antibiotic sensitivity of the isolated bacteria from 179 patients undergoing transurethral resection of the prostate were analysed. The patients were randomized into a group receiving a short course of cefotaxime in conjunction with the operation and a control group given no antibiotics. Preoperatively 70 patients had bacteriuria (greater than or equal to 10(7) CFU/l) with a predominance of Gram-negative bacteria (57 isolates, mainly Escherichia coli, Enterobacter, Klebsiella ssp, Proteus ssp), although Gram-positive species (24 isolates, mainly enterococci and Staphylococcus epidermidis) were also frequently encountered. Preoperatively isolated pathogens were evenly distributed in both groups and the sensitivity pattern was comparable. In the cefotaxime group postoperative recurrence of the preoperatively identified bacteria occurred in a lower frequency (11/43) than persistence in the control group (24/38). Only Gram-negative pathogens were isolated from patients with postoperative septicemia and upper urinary tract infections indicating that it is most important to direct prophylaxis against Gram-negative bacteria. A high degree of sensitivity against cefotaxime, gentamicin, trimethoprim, co-trimazine and a combination of ampicillin and mecillinam was recorded among both pre- and postoperatively isolated bacteria.
