Lasers (Laser)

An optical source that emits photons in a coherent beam. Light Amplification by Stimulated Emission of Radiation (LASER) is brought about using devices that transform light of varying frequencies into a single intense, nearly nondivergent beam of monochromatic radiation. Lasers operate in the infrared, visible, ultraviolet, or X-ray regions of the spectrum.

1.	Cicatrix (Scar) 01/01/2015 - "A number of treatments are available for red residual lesions but thanks to its effect on erythematous and vascular lesions, PDL has been shown to provide the most reproducibly good results and is the laser method of choice for this type of scar. " 01/01/2012 - "The data confirm the efficacy of all three treatments, with the most effective scar treatment being the fat grafts mixed with PRP, followed by skin resurfacing with nonablative laser. " 01/01/2002 - "Laser resurfacing using the high-energy, pulsed and scanned CO2 laser produces the most dramatic improvement in severe photo-induced facial rhytides and deeply atrophic scars. " 05/01/2011 - "Every lesion (10/10) that initially measured <2 mm resolved completely after laser treatment with minimal scarring noted at the treatment site based on histology. " 10/01/2009 - "In our patients, using this sequential laser device achieved an almost complete clearance of the VM with no scarring."
2.	Neoplasms (Cancer) 04/01/2012 - "Laser + SWNT-GC afford a remarkable efficacy in suppressing tumor growth in animal cancer models, in many cases resulting in complete tumor regression and long-term survival. " 06/01/2010 - "The laser was not helpful with highly vascular tumors. " 05/01/2009 - "Early glottic cancer can be cured with transoral laser resection, but in cases with anterior commissure involvement, there is still controversy concerning the best treatment modality. " 09/01/1989 - "It is concluded that the endoscopic use of the AYG laser for the destruction of tumors, cicatrices, and granulations in the tracheal and bronchial lumen both as the first stage of surgical treatment and as an independent palliative method in inoperable patients is highly effective and safe." 01/01/1987 - "Endoscopic laser treatment was found to be most effective when the tumor was polypoid in appearance bronchoscopically, with little or no submucosal invasion or peribronchial extension seen on CT. "
3.	Pain (Aches) 01/01/2014 - "However, in most studies laser therapy was associated with significant reduction in the intensity and frequency of pain compared with other treatment strategies, a few studies revealed that between laser and placebo group there was not any significant difference according to the analgesic effect. " 01/01/1990 - "By persons with stomatopyrosis and stomatodiniae symptoms analgetic effect was attained through the therapy with the laser already after the first application, and the pain and aches intensity was relieved every day during the therapy, by stomatodinae to complete healing. " 08/01/2008 - "Despite contradictory reports on the effect of laser light on cell proliferation, studies have shown that appropriate doses and wavelengths of laser light are therapeutically beneficial in tissue repair and pain control. " 12/01/2003 - "Several studies have shown good results with the use of low-energy laser, with the aim of accelerating the process of wound healing and promoting pain relief. " 11/01/2015 - "By 12 weeks of treatment, there was a significant improvement in pain, ROM, ESR and leucocytes levels in laser group compared with PEMF, while there was no significant difference in knee circumferences and the 6-min walk test (6MWT) between both groups. "
4.	Macular Edema 03/01/2000 - "Macular edema disappeared or was dramatically reduced in all cases after laser treatment. " 01/01/1990 - "In most cases, diabetic macular edema is treated successfully with central laser photocoagulation. " 08/01/2009 - "However, focal/grid laser photocoagulation continues to be the only proven safe and effective treatment for diabetic macular edema." 06/01/2000 - "Overall, grid laser photocoagulation for diabetic macular edema is a very cost-effective treatment based on the results of this cost-utility analysis." 10/01/2015 - "Focal laser photocoagulation remains the gold standard for macular edema not involving the fovea (and therefore usually good visual acuity). "
5.	Acne Vulgaris 03/01/2010 - "Further studies are warranted to establish optimal parameters for photosensitizer use combined with light therapy for treatment of moderate-to-severe acne; however, the combined use of ALA and a 532 nm laser suggests promising results for acne treatment." 01/01/2011 - "Many laser and light-based treatments have shown excellent clinical results in the reduction of inflammatory acne lesions and improved acne severity. " 01/01/2015 - "Significant improvement in acne was seen in both the combined (laser and peel) and chemical peel alone treatment arms (P < .0005 and P = .001). " 04/01/2012 - "This laser treatment was rapid and effective for treating not only the inflammatory but also the noninflammatory acne lesions when compared with the control side. " 12/01/2006 - "All patients had a reduction in the inflammatory acne lesion count on the laser-treated side, which was statistically significantly greater on the laser-treated side compared with the side treated physically (p=0.039, Wilcoxon signed ranks test).
