Summary of "The therapeutic effects of 1540-nm nonablative fractional erbium laser on macular amyloidosis, a randomized clinical trial."

This aim of this study was determining the effect of 1540-nm nonablative fractional erbium on macular amyloidosis. This phase-II clinical trial study has been performed with parallel group with blinding of the evaluator. The skin lesions of the patients (15 patients and 30 lesions) with cutaneous macular amyloidosis were randomly assigned into laser and no-treatment groups. In the laser group, treatment was performed by 1540-nm nonablative fractional erbium laser. Thereafter, the patients' lesions were compared in terms of pigmentation, rippling, thickness, and subjective response. The lesions of the intervention group significantly improved in the three-month follow-up compared to the control group (in the control and intervention group, improved pigmentation was observed in 20 and 53.3% with p = 0.02, improved rippling in 6.7 and 60% with p = 0.007, diminished lichenification in 0 and 53.1% with p = 0.007, and overall lesion improvement in 20 and 60% with p = 0.03, respectively). In investigating the subjective response through patient global assessment, the patients in the intervention group, had a greater satisfaction (p = 0.01). There was a considerable improvement of pruritus in the intervention group (p = 0.001). Use of 1540-nm nonablative fractional erbium laser offered a suitable efficacy to treat macular amyloidosis without significant complications.

Medical and Biotech [MESH] Definitions

Treatment using irradiation with LASER light of low power intensity so that the effects are not due to heat, as in LASER THERAPY. These non-thermal effects are thought to be mediated by a photochemical reaction that alters CELL MEMBRANE PERMEABILITY, leading to increased mRNA synthesis and CELL PROLIFERATION. Low-level laser therapy has been used for a wide variety of conditions, but most frequently for wound healing and pain control.

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).

Erbium. An element of the rare earth family of metals. It has the atomic symbol Er, atomic number 68, and atomic weight 167.26.

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.

A form of MACULAR DEGENERATION also known as dry macular degeneration marked by occurrence of a well-defined progressive lesion or atrophy in the central part of the RETINA called the MACULA LUTEA. It is distinguishable from WET MACULAR DEGENERATION in that the latter involves neovascular exudates.
