Aims: 30-40% of individuals will be affected by varicose veins during their lifetime. Many will contemplate treatment and will access the (Inter)net for information. The aim of this study is to determine whether New Zealand-based websites are an accurate source of information for the public.

Methods: Inclusion criteria were New Zealand based websites that contained information on varicose vein treatments. These websites were identified using the search-engines Google and Yahoo. The first 60 websites from each were evaluated and subdivided into 4 groups based on web-site ownership: (1) Vein clinic/hospital; (2) Appearance medicine; (3) Online stores; (4) Health editorials; and (5) Medical resources.

Results: 46 of the 120 websites satisfied the inclusion criteria. 18 websites (39%) explained what varicose veins were. Information about treatment options was most comprehensive in the "Vein clinic/hospital" group. The "Appearance medicine" group mostly contained information on outpatient interventional therapies. "Health editorial" sites had lifestyle modification options. All the online herbal/health stores mentioned herbal treatment options.

Conclusion: Few websites fully informed patients about treatment options while some simply advertised non-evidence based treatments. This study suggests that the Internet is not a reliable source of information and does not accurately inform patients about varicose veins and the treatment options.

Preventing recurrence of venous leg ulcers can be achieved through strongest tolerated compression and endo-venous ablation surgery, but it is not clear how often this is done in practice. This study explores (1) nurses' awareness of strongest tolerated compression and endo-venous ablation surgery as prophylactic treatments for venous leg ulcer, (2) how often these treatments are offered, and (3) assessment of the barriers and enablers to deploying those treatments using the capabilities, opportunities and motivations model of behaviour change. An online cross-sectional survey was conducted among nurses who treat and manage venous leg ulcers across the United Kingdom.

There is a practice gap with regard to knowledge of normal oral mucosa variants, performance of the oral examination, and competence in diagnosing and treating oral mucosal disorders. The oral mucosa falls within the purview of dermatology.

Objective: This study aimed to evaluate the performance of an innovative multicomponent compression system in a single bandage (UrgoK1, Laboratoires Urgo, France) in the treatment of patients with venous leg ulcers (VLUs) and/or lower limb oedema in everyday practice.

Method: A prospective, observational, clinical study with the evaluated compression system was conducted in 39 centres in Germany between March 2022 and July 2023. Main outcomes included a description of the treated patients, changes in wound healing and oedema progression, local tolerance and acceptability of the compression system.
