title: Photopneumatic therapy for the treatment of keratosis pilaris.
abstract: BACKGROUND
  Current treatment options for keratosis pilaris (KP) are limited and are often found to be unsatisfactory to patients.
  
  
  OBJECTIVE
  Pilot study to determine if photopneumatic therapy (PPx) can improve the erythema and skin texture in KP.
  
  
  METHODS
  Ten patients with KP were treated with one session of PPx on the upper arm and then evaluated one month later for treatment efficacy.
  
  
  RESULTS
  Average investigator-assessed improvement was 27% in erythema and 56% in skin texture roughness. Average patient self-reported improvement was 52% in erythema and 53% in skin texture. The mean satisfaction score was 6.3 on a scale of 1 to 10 (median 7.5) and 8 out of 10 participants reported they would choose to receive PPx for their KP again in the future.
  
  
  CONCLUSIONS
  Small number of patients, short follow-up period, and lack of blinding of the examiner and the patients making recall bias possible.
  
  
  CONCLUSIONS
  One treatment of PPx improved both the erythema and redness associated with KP over at least a one month period.
