| protein-calorie malnutrition in patients with colorectal cancer. | protein-calorie malnutrition, as determined by anthropometric measures and laboratory tests, was assessed in 17 preoperative patients with colorectal cancer and 47 control patients. the cancer patients had significant deficits in visceral protein and skeletal muscle and no deficit in fat stores. greater attention should be given to preoperative nutritional assessment and to the correction of protein deficits. | 1998 | 104851 |
| asymptomatic bacteriuria in pregnancy: epidemiological, clinical and microbiological approach. | asymptomatic urinary tract infection is a risk factor for fetal and maternal morbidity including development of pyelonephritis, premature labor and impaired intra-uterine development. in this study, 326 pregnant and 100 non-pregnant control women were screened for significant asymptomatic bacteriuria from april 8 to july 25, 1997 to gain insight into the prevalence rate, clinical characteristics of the disease and microbiological assessments of the causative agents. all the subjects were clinica ... | 1998 | 10214459 |
| antibacterial activity of peritoneal exudate in patients treated with 2 g cefotiam for surgical anti-microbial prophylaxis. | the objective of this study was to investigate the presence of antibacterial activity in peritoneal exudate (pe) of patients treated with cefotiam (cft). cft (2 g) was administered as a 'single-shot' antimicrobial prophylaxis to 6 patients at the beginning of colorectal resection. samples of pe were collected from each patient on days 1, 2 and 3 after surgery. cft was detectable in the samples of day 1 for 5 of the 6 patients. the influence of pe on antibacterial activity of the antimicrobial dr ... | 1998 | 9612603 |
| [bactericidal activity and capacity for selection of mutants resistant to imipenmen and meropenem in strains of proteus, morganella and providencia]. | to compare the bactericidal activity and frequency of mutation for meropenem and imipenem against proteus mirabilis, morganella morganii and providencia rettgeri. | 1998 | 9763741 |
| studies on the formation of crystalline bacterial biofilms on urethral catheters. | a model of the catheterised bladder was used to test the ability of urease-producing urinary tract pathogens to encrust urethral catheters. encrustation was assessed by determining the amounts of calcium and magnesium deposited on the catheters and visualised by scanning electron microscopy. urease-positive morganella morganii, klebsiella pneumoniae, and pseudomonas aeruginosa failed to raise the urinary ph and form crystalline biofilms. in contrast, strains of proteus mirabilis, proteus vulgari ... | 1998 | 9832268 |
| natural antibiotic susceptibility of providencia stuartii, p. rettgeri, p. alcalifaciens and p. rustigianii strains. | the natural antibiotic susceptibility of 38 providencia rettgeri, 35 p. stuartii, 23 p. alcalifaciens and 20 p. rustigianii strains was examined. mic values were determined by a microdilution procedure and evaluated by a table calculation programme. p. stuartii was the least susceptible providencia sp. and was naturally resistant to tetracyclines, some penicillins, older cephalosporins, sulphamethoxazole and fosfomycin and to antibiotics to which other species of enterobacteriaceae are also resi ... | 1998 | 9839568 |
| antibacterial activity of human pleural fluid: alone and in combination with antibiotics. | this study investigated the antibacterial activity of human pleural fluid (hpf) and its interaction with gentamicin (gm), meropenem (mrpm), ciprofloxacin (cpfx) and clarithromycin (cltm) against escherichia coli k-12, proteus rettgeri (sanelli) and staphylococcus aureus. minimal inhibitory concentrations or volumes, expressed as mic or volume percentage (miv, v/v%), were measured using a micro-dilution technique in microtiter plates. the antimicrobial activity of hpf combinations with antimicrob ... | 1998 | 9916908 |
| adenocarcinoma of the prostate in perspective. | adenocarcinoma of the prostate is responsible for one of every nine deaths from cancer in canada. in this review epidemiologic factors are considered and current staging systems are outlined. the american urological system is recommended for staging because of its ability to reflect changes in the understanding of the biologic behaviour of this neoplasm. the adoption of a quantitative grading scheme is suggested to complement the information obtained from the staging assessment. the routes of sp ... | 1998 | 105800 |
| controlled trial of disodium cromoglycate in chronic persistent ulcerative colitis. | oral disodium cromoglycate (200 mg qds) has been tested in 26 patients with ulcerative colitis that was resistant to medical treatment. in a double-blind crossover trial disodium cromoglycate and placebo were added to conventional treatment in random order, each for four weeks. there was no significant difference in therapeutic effect between disodium cromoglycate and placebo. | 1998 | 105970 |
