Background

Diaper dermatitis is caused by overhydration of the skin, maceration, prolonged contact with urine and feces, retained diaper soaps, and topical preparations and is a prototypical example of irritant contact dermatitis. Signs and symptoms are restricted in most individuals to the area covered by diapers.[1, 2]

The photograph below depicts a 3-week-old female neonate with diaper rash.

Pathophysiology

Diaper rash affects the areas within the confines of the diaper. Increased wetness in the diaper area makes the skin more susceptible to damage by physical, chemical, and enzymatic mechanisms. Wet skin increases the penetration of irritant substances. Superhydration urease enzyme found in the stratum corneum liberates ammonia from cutaneous bacteria. Urease has a mild irritant effect on nonintact skin. Lipases and proteases in feces mix with urine on nonintact skin and cause an alkaline surface pH, adding to the irritation. (Feces in breastfed infants have a lower pH, and breastfed infants are less susceptible to diaper dermatitis.) The bile salts in the stools enhance the activity of fecal enzymes, adding to the effect.

Candida albicans has been identified as another contributing factor to diaper dermatitis; infection often occurs after 48-72 hours of active eruption. It is isolated from the perineal area in as many as 92% of children with diaper dermatitis. Other microbial agents have been isolated less frequently, perhaps more as a result of secondary infections.

Epidemiology

Race

No racial difference is observed.

Sex

No sexual difference is noted.

Age

Diaper dermatitis commonly affects infants, with peak incidence occurring when the individual is aged 9-12 months. One study determined that at any given time, diaper dermatitis is prevalent in 7-35% of the infant population.[3]

Diaper dermatitis can affect persons of any age who wear diapers, in particular, elderly people.
