A comparative study of the cytotoxicity of silver-based dressings in monolayer cell, tissue explant, and animal models.

Over the past decade, a variety of advanced silver-based dressings have been developed. There are considerable variations in the structure, composition, and silver content of these new preparations. In the present study, we examined five commercially available silver-based dressings (Acticoat, Aquacel Ag, Contreet Foam, PolyMem Silver, Urgotul SSD).

The validity and reliability of two asthma knowledge questionnaires.

Background: This study aimed to develop and validate two asthma knowledge questionnaires, one for consumers (CQ) and one for health care professionals (HQ) to fill an existing gap in the literature.

Methods: Following development and pilot testing, the revised CQ and HQ were administered to respiratory physicians, pharmacists and people with asthma and without asthma.

Results: Both the CQ and HQ were shown to be reliable with Cronbach's alpha of 0.
