The aim of the study was to investigate the bacterial profile of chronic venous leg ulcers and the importance of the profile to ulcer development. Patients with persisting venous leg ulcers were included and followed for 8 weeks. Every second week, ulcer samples were collected and the bacterial species present were identified. More than one bacterial species were detected in all the ulcers. The most common bacteria found were Staphylococcus aureus (found in 93.5% of the ulcers), Enterococcus faecalis (71.7%), Pseudomonas aeruginosa (52.2%), coagulase-negative staphylococci (45.7%), Proteus species (41.3%) and anaerobic bacteria (39.1%). Resident bacterial species were present in all the ulcers. In 76% of the ulcers, two or more (up to five) resident bacterial species were found. The most common resident bacterial species were S. aureus and P. aeruginosa. Furthermore, ulcers with P. aeruginosa were found to be significantly larger than ulcers without the presence of P. aeruginosa (P < 0.005). Our study demonstrated that the chronic wound is colonised by multiple bacterial species and that once they are established many of them persist in the wound. Our results suggest that the presence of P. aeruginosa in venous leg ulcers can induce ulcer enlargement and/or cause delayed healing.

The aim of the study was to compare three sampling techniques used in routine diagnostics to identify the microbiota in chronic venous leg ulcers. A total of 46 patients with persisting venous leg ulcers were included in the study. At inclusion, swab, biopsy and filter paper pad samples were collected. After 4 weeks, additional biopsy and filter paper pad samples were collected. Bacteria were isolated and identified at species level by standard methods. The most common bacterial species detected was Staphylococcus aureus found in 89% of the ulcers. No methicillin-resistant S. aureus isolates were found. We did not find any significant differences regarding the bacterial species isolated between the three sampling techniques. However, using multiple techniques led to identification of more species. Our study suggests that it is sufficient to use swab specimens to identify the bacterial species present in chronic wounds, thus avoiding complications during and after biopsy sampling.

In this study, the ibuprofen foam dressing was shown to consistently relieve wound pain in exuding wounds of various aetiologies, irrespective of basal pain intensity. The data suggest that local pain relief by an ibuprofen foam dressing is possible in the most common, painful, exuding, chronic and acute/traumatic wounds and so is a safer alternative to systemic pain treatment.

The discreet design of the compact catheter significantly improved patient quality of life related to intermittent self-catheterization.
