[Clinical audit of negative pressure therapy].

Negative pressure therapy is used to encourage the healing of a wound. In Bichart Hospital, in Paris, a clinical audit was carried out to assess how the therapy is managed. It emerged that the procedure is used in accordance with recommendations and that the information given to the patient is sufficient.

Randomized controlled trial of chlorhexidine dressing and highly adhesive dressing for preventing catheter-related infections in critically ill adults.

Rationale: Most vascular catheter-related infections (CRIs) occur extraluminally in patients in the intensive care unit (ICU). Chlorhexidine-impregnated and strongly adherent dressings may decrease catheter colonization and CRI rates.

Objectives: To determine if chlorhexidine-impregnated and strongly adherent dressings decrease catheter colonization and CRI rates.

Dressing disruption is a major risk factor for catheter-related infections.

Objective: Major catheter-related infection includes catheter-related bloodstream infections and clinical sepsis without bloodstream infection resolving after catheter removal with a positive quantitative tip culture. Insertion site dressings are a major mean to reduce catheter infections by the extraluminal route. However, the importance of dressing disruptions in the occurrence of major catheter-related infection has never been studied in a large cohort of patients.

Economic evaluation of chlorhexidine-impregnated sponges for preventing catheter-related infections in critically ill adults in the Dressing Study.

Background: The randomized two-way factorial Dressing Study (1,636 patients, 28,931 catheter days) showed that a chlorhexidine-impregnated sponge decreased the incidence of major catheter-related infections from 1.4‰ to 0.6‰ catheter days, and that scheduled dressing changes every 7 days was not inferior to scheduled changes every 3 days.

Chlorhexidine-impregnated sponges and less frequent dressing changes for prevention of catheter-related infections in critically ill adults: a randomized controlled trial.

Context: Use of a chlorhexidine gluconate-impregnated sponge (CHGIS) in intravascular catheter dressings may reduce catheter-related infections (CRIs). Changing catheter dressings every 3 days may be more frequent than necessary.

Objective: To assess superiority of CHGIS dressings regarding the rate of major CRIs (clinical sepsis with or without bloodstream infection) and noninferiority (less than 3% colonization-rate increase) of 7-day vs 3-day dressing changes.

Organ-targeted mutagenicity of nitrofurantoin in Big Blue transgenic mice.

Nitrofurans are widely used in human medicine, as nitrofurantoin and nifuroxazide, still prescribed for long-term antimicrobial prophylaxis of urinary tract and gastrointestinal infection in humans respectively. Recent experiments in mammals, as well as reports mentioning toxic effects in humans associated with a long-term use, specially in the case of nitrofurantoin, raised the need for reevaluating their genotoxicity. The objective of this study was to determine whether these two compounds induce a mutagenic effect in the Big Blue transgenic mouse mutation assay.

Comparison of kinetics of induction of DNA adducts and gene mutations by a nitrofuran compound, 7-methoxy-2-nitronaphtho[2,1-b]furan (R7000), in the caecum and small intestine of Big Blue mice.

In previous experiments, i.p. injection of the 5 nitronaphthofuran derivative 7-methoxy-2-nitronaphtho[2,1-b]furan (R7000) to lacI transgenic Big Blue mice led to an increase in the mutant frequency (MF), especially in the caecum and the small intestine.
