Comparison of Electrodessication, Potassium Titanyl Phosphate (KTP) Laser and Pulsed Dye Laser for Treatment of Cherry Angiomata - Full Text View

Purpose

The primary objective of this study is to determine whether laser treatments over 6 weeks using the pulsed dye laser system or the potassium titanyl phosphate (KTP) laser are effective in patients with cherry angiomas as observed by a physician provider and the subject.

The investigators hypothesize that the two laser treatments will be an effective tool for treating cherry angiomas. The investigators aim to compare these modalities to electrodessication, as all three modalities are considered the current standard of care. Electrodessication can result in atrophic lesions at the site of the treated cherry angiomas.

In summary, the goal of this project is to compare the non-ablative pulsed dye laser and the AuraTM potassium titanyl phosphate (KTP) laser to each other and to the current standard of care, electrodessication.

Primary Outcome Measures:

Mean Changes in Color, Texture, and Size of Cherry Angiomata From Baseline to 3 Months After the Second Treatment by Treatment Type as Assessed by Blinded Raters [ Time Frame: Baseline and 3 months ] [ Designated as safety issue: No ]
Each subject received all 3 treatments. Serial standardized photographs evaluated for color,texture and size by 2 blinded dermatologists using ordinal visual analog scales from 0 to 10(color: 0=skin colored, 5=red, 10=purple; texture: 0=flat, 5=mildly elevated, 10=elevated; size: 0=0mm, 10=10 mm).

Enrollment:	15
Study Start Date:	September 2006
Study Completion Date:	October 2007
Primary Completion Date:	October 2007 (Final data collection date for primary outcome measure)

Arms	Assigned Interventions
Experimental: electrodessication (ED) Treatment over 6 weeks using electrodessication (ED) to remove cherry angiomas. Each participant received treatment with PDL, KTP laser, and electrodesiccation to separate randomly selected areas on the torso, with each area bearing 4 cherry angiomata.	Procedure: Electrodessication Treatment applied to a third of the torso at each study visit.
Experimental: pulsed dye laser (PDL) Treatment over 6 weeks using pulsed dye laser (PDL) to remove cherry angiomas. Each participant received treatment with PDL, KTP laser, and electrodesiccation to separate randomly selected areas on the torso, with each area bearing 4 cherry angiomata.	Procedure: Pulsed dye laser (PDL) Laser treatment applied to a third of the torso at each study visit.
Experimental: potassium titanyl phosphate (KTP) laser Treatment over 6 weeks using potassium titanyl phosphate (KTP) laser to remove cherry angiomas. Each participant received treatment with PDL, KTP laser, and electrodesiccation to separate randomly selected areas on the torso, with each area bearing 4 cherry angiomata.	Procedure: potassium titanyl phosphate (KTP) Laser treatment applied to a third of the torso at each study visit.
