Sugar is used as a therapy in the treatment of decubitus ulcers (pressure
sores) because the osmolality (the high sugar content) is not a favorable
place for bacteria to live.  The wound is irrigated daily and new, granulated
sugar is applied.  As a nursing student, training in the second largest
publice hospital in the U.S. (New Orleans), I saw remarkable granulation
tissue and a decrease in prurulent drainage and necrotic tissue.  Needles to
say, daily care, cleanliness of the patient and good aseptic technique are
also essential.  Sugar has also been combined with betadine (iodine solution)
and applied to these wounds as a paste.

Perhaps, there is a link between this therapy and the use of honey in wounds.
 I am intrigued by the botulism associated with sugar or corn syrup on the
nipples.  I'll keep my eyes and ears open and watch for more info.

Hope this sugar "trivia" helps.  :)
