MINNEAPOLIS – A small study of cloth diaper–wearing toddlers with unusual vesiculobullous and erosive lesions found that the rashes fully resolved with aggressive barrier cream application and a switch to disposable diapers.
The four patients had previously received aggressive work-ups, including biopsy in some cases; all had received systemic antibiotics. Katya L. Harfmann, MD, a pediatric dermatologist at Nationwide Children’s Hospital in Columbus, Ohio, was the lead author in a poster presentation at the annual meeting of the Society for Pediatric Dermatology.
The toddlers, aged 17 months to 2 years, had diaper dermatitis of several weeks’ to several months’ duration, with a presentation of vesicles, bullae, and erosions. All of the children had been placed in cloth diapers since birth. The patients, three of them male, had undergone work-ups that included bacterial culture for three patients, herpes simplex virus (HSV) polymerase chain reaction (PCR) testing for three patients, and blood work for two patients. HSV cultures and viral cultures were each performed on one patient. With the exception of one bacterial culture returning methicillin-sensitive Staphylococcus aureus (MSSA), all results were negative.
Two patients underwent biopsies. One biopsy was reported as “spongiform dermatitis,” while the other was read as a “nonspecific ulcer.”
A variety of treatments had been tried for the children. All of the children had received systemic antibiotics; two received systemic antivirals as well. Two patients each received topical steroids and topical antibacterials, and one patient also received topical dapsone. Many treatments were given “in repetitive courses, without improvement in the lesions,” wrote Dr. Harfmann and her coauthor.
The families were advised to switch to exclusive use of disposable diapers and to begin frequent use of a zinc oxide–based thick diaper paste. For all patients, the diaper dermatitis completely resolved within as little as 2 weeks.
The medical literature documents an increased risk of diaper dermatitis with cloth diaper use. “Despite this knowledge in the medical community, nearly half of cloth diaper–using parents select cloth diapers with the assumption that diaper rash is less frequent with their usage,” the researchers noted.
They pointed out that bullae in the diaper region are often thought to be associated with such infectious conditions as impetigo and herpes simplex infection, and can also be associated with immunobullous disorders. Diaper changes are less frequent in older children, though, giving the opportunity for prolonged contact with the irritating chemicals in feces and urine. This prolonged contact, exacerbated by the moister environment of a cloth diaper, may account for the unusual, severe presentation seen in these cases.
Also, the three boys had vesicular lesions on their testicles and penis. “It is possible that the thinner skin in these areas has a lower irritation threshold or that the redundancy of skin often seen on the penile shaft leads to trapping of irritants with extended diaper use,” they wrote.
“An empiric trial of disposable diapers exclusively with aggressive barrier cream application for several weeks may eliminate the need for more invasive procedures and laboratory tests,” wrote Dr. Harfmann and her coauthor.
They reported no conflicts of interest.
