Pulsed Dye Laser Treatment of Acne Vulgaris

2014-08-27 03:16:33 | BioPortfolio

Summary

The results of pulsed dye laser (PDL) treatment of acne vulgaris published so far are controversial: Whereas Seaton et al. described a marked improvement of mild-to-moderate acne after low-fluence pulsed-dye laser therapy, Orringer et al. were unable to replicate said results in a similar, albeit not identical, study design. More recently published studies failed to resolve the controversy, varying in terms of treatment procedure(s) as well as results.

While published results are certainly promising enough to be followed up by independent research, they are insufficient to justify the abdication of methods with proven efficacy. Considering patient treatment ethics and the short 'window of opportunity' for scar prevention when active inflammatory lesions are present, the investigators planned the adjuvant application of the PDL in the present study, providing all patients with the well established and evidentially effective modality of a fixed-combination clindamycin 1%-benzoyl peroxide 5% hydrating gel (C/BPO). The goal of the study was the assessment of the efficacy and safety of a low-fluence PDL treatment in addition to C/BPO in patients with facial inflammatory acne.

Medical and Biotech [MESH] Definitions

A pharmaceutical preparation of adapalene and benzoyl peroxide that is used as a DERMATOLOGIC AGENT for the topical treatment of ACNE.

A peroxide derivative that has been used topically for BURNS and as a dermatologic agent in the treatment of ACNE and POISON IVY DERMATITIS. It is used also as a bleach in the food industry.

A technique utilizing a laser coupled to a catheter which is used in the dilatation of occluded blood vessels. This includes laser thermal angioplasty where the laser energy heats up a metal tip, and direct laser angioplasty where the laser energy directly ablates the occlusion. One form of the latter approach uses an EXCIMER LASER which creates microscopically precise cuts without thermal injury. When laser angioplasty is performed in combination with balloon angioplasty it is called laser-assisted balloon angioplasty (ANGIOPLASTY, BALLOON, LASER-ASSISTED).

Techniques using laser energy in combination with a balloon catheter to perform angioplasty. These procedures can take several forms including: 1, laser fiber delivering the energy while the inflated balloon centers the fiber and occludes the blood flow; 2, balloon angioplasty immediately following laser angioplasty; or 3, laser energy transmitted through angioplasty balloons that contain an internal fiber.

Severe and chronic form of acne characterized by large, burrowing abscesses associated with disfigurement.
