Perineal dermatitis in the elderly. A critical review of the literature.

The review of literature revealed a significant lack of research on the pathogenesis of perineal dermatitis in the elderly. The majority of what is known about this condition stems from the pediatric population. The differences between TEWL and skin surface pH levels in pediatric and geriatric skin raises questions about the further generalizability of the pediatric studies. There appears to be some controversy in the literature regarding whether baseline TEWL is increased or decreased in cutaneous aging. The literature did reveal some data indicating that skin surface pH increases with age; however, no data on the perineum was found. No studies examining the role of TEWL and skin surface pH and its association in the development of perineal dermatitis in the elderly were found. Additionally, no studies were found that examine the nursing variables identified in the literature search. The paucity of scientific data on this serious and costly condition warrants additional research in this area.
