Negative pressure dressings as an alternative technique for the treatment of infected wounds.

Coverage of wounds caused by infection and subsequent treatment often are variable because of the location of the wound and wound size. Although much research has been done to expand the indications of negative pressure wound treatment systems, little investigation has been done to quantify the reduction of wound size for vacuum-assisted closure treatment in the presence of infection. In this series, 14 patients who had wounds caused by infections were treated with the vacuum-assisted wound closure system.

Yawning?

Since antiquity yawning has attracted a moderate interest among philosophers, psychologists, physiologists, as well as educators, moralists and physicians. Organisms from birds to men and from the womb to the deathbed were found to be displaying it. While sometimes satisfying to the producer, its display is offensive to the lay observer.
