The patients will be screened for study enrollment in a private clinic room within the dermatology clinic at One Hundred Oaks. Patients will be presented with a study summary sheet and a consent form. They will be allowed to ask questions pertaining to the study protocol. Information provided to them will be that found in the study protocol alone. If desired, informed consent can be taken home with the patient to consider, and enrollment can be performed at a later date. In that instance, the patient would be brought back for an additional visit at the time of consent and study enrollment. Study enrollment and first treatment will be performed on the day of study consent. Digital photographs of each elbow or each knee (treatment and control) will be taken on the day of enrollment to serve as a baseline evaluation. The number of lesions (including papules, plaques and vesicles) will be recorded for the treatment and control elbow or knee. Measurements of each lesion will be taken and recorded as well. This data will be written in a chart and stored in the PI's notebook in a locked cabinet in the department of dermatology. Digital photographs will be printed out on the same day as the visit and placed in the notebook as well. Two copies of each photograph will be made. Each photograph will be assigned a letter, A through Z, based on a code for each patient. One copy of each set of photographs will also include the date. No patient identifiable features will be included in the photograph such as the face or eyes. Each photograph will be of the treated or control area only. The code to identify patient photographs will be assigned by the Data and Safety Monitor and kept in a separate locked cabinet. The code will be broken following the blinded evaluation of the photographs by co-investigator.
