:shifty. I notice the smell of rancid body oils in sheets. I sometimes can smell it in the houses I visit. Sometimes it is severe and very unpleasant. At one friend's house I would have to walk by her bedroom to use the bathroom and the smell really was strong to me.
Yeast is by far the most common type of organism found in a diaper rash. The organism is quite prevalent and thrives on warm, moist skin. Yeast involvement should be suspected in any diaper rash that hasn't improved dramatically with 72 hours of appropriate therapy.
The most common cause of diaper rash is due to the use of the diaper itself. This is from wet skin being in contact with the diaper, urine and stool. Typically there is redness and swelling of the skin along the top of the diaper, over the bottom and around the legs.
