Dye Laser treatment of port-wine stains: Comparison of the continuous-wave Dye Laser with a robotized scanning device and the pulsed Dye Laser☆
Journal of the American Academy of Dermatology, 1995Co-Authors: Jeffrey S. Dover, Roy G. Geronemus, Robert S. Stern, Deirdre O'hare, Kenneth A. ArndtAbstract:Abstract Background: Despite good results in the treatment of most port-wine stains (PWS) with continuous-wave visible-light Lasers, light PWS and those in certain locations respond less favorably and have a higher risk of scarring. Robotized scanning devices such as the Hexascan device have been developed for continuous-wave Laser sources to produce greater target specificity, to increase reproducibility of results, and to decrease the incidence of adverse effects. Objective: The purpose of this study was to compare the effects of the same wavelength of light (585 nm) on test sites within PWS with the flashlamp-pumped pulsed Dye Laser and a continuous-wave tunable Dye Laser scanned through a Hexascan robotized scanning device. Methods: Two adjacent, noncontiguous sites within PWS were treated in 29 patients, one site with the flashlamp-pumped pulsed Dye Laser and the other with an argon-pumped continuous-wave tunable Dye Laser affixed to a Hexascan device. Results: Twenty-eight patients completed the study. The pulsed Dye Laser was found to be superior to the continuous-wave Dye Laser with the Hexascan device in 45% of patients, whereas the continuous-wave tunable Dye Laser with the Hexascan device was considered superior in 15%. There was no difference in the remaining 40%. Undesirable side effects were infrequent with both treatments. There was no significant difference in hypopigmentation or atrophic and hypertrophic scarring, but hyperpigmentation was more frequent with the continuous-wave Dye Laser with the Hexascan device. Conclusion: Both the pulsed Dye Laser and continuous tunable-wave Dye Laser with the Hexascan device produce slight lightening after one treatment. The pulsed Dye Laser produces slightly greater lightening than the continuous-wave tunable Dye Laser with the Hexascan device 6 weeks after treatment of test areas within PWS in 40% of those treated. It also produced slightly less hypopigmentation and hyperpigmentation.

Treatment of spider veins with the 595 nm pulsed-Dye Laser.
Journal of the American Academy of Dermatology, 1998Co-Authors: E F Bernstein, D B Brown, Gary Lask, Roy G. Geronemus, J. Lowery, J HsiaAbstract:Previous attempts to treat spider veins with the conventional 585 nm pulsed-Dye Laser with a 0.5-ms pulse duration have been relatively ineffective. Recently, a new pulsed-Dye Laser that is tunable from 585 to 600 nm with a pulse duration 3 times longer than previously available Lasers has preliminarily been shown to be effective for treatment of spider veins. Our purpose was to evaluate the effectiveness of multiple treatments with the tunable long-pulse Dye Laser in treatment of spider veins of the lower extremity. Ten female volunteers were treated in two separate areas containing blue or red linear spider veins less than 1.5 mm in diameter. Treatments were administered with the pulsed-Dye Laser with a 1.5-ms pulse duration and 595-nm light at fluences of 15 and 20 J/cm2, and each subject received a total of 3 treatments at each site, administered at 6-week intervals. Photographs were taken before and 6 weeks after the last treatment. Computer-based image analysis showed clearing of more than three fourths of veins after 3 treatments with 15 or 20 J/cm2. Side effects were minimal and the treatments were well tolerated. The 595 nm, 1.5 ms pulse duration, pulsed-Dye Laser is safe and effective for treating blue or red spider veins of the lower extremities less than 1.5 mm in diameter in nontanned patients with Fitzpatrick skin types I and II. Multiple treatments improve on the results obtained after a single treatment.

pulsed Dye Laser treatment of warts
Archives of Family Medicine, 1995Co-Authors: Arielle N.b. Kauvar, David H. Mcdaniel, Roy G. GeronemusAbstract:OBJECTIVE: To determine the safety and efficacy of the flashlamp-pumped pulsed Dye Laser for the treatment of uncomplicated and recalcitrant warts. DESIGN: Observational study. PATIENTS: A total of 142 patients with 703 recalcitrant and 25 previously untreated warts consecutively referred to two tertiary care Laser centers from July 1993 through January 1994. INTERVENTION: Photocoagulation with the flashlamp-pumped pulsed Dye Laser. MAIN OUTCOME MEASURES: Complete resolution of treated warts after a follow-up ranging from 3 to 9 months. RESULTS: The overall response rates were 99% for body, limb, and anogenital warts; 95% for hand warts; 84% for plantar warts; and 83% for periungual warts. Side effects were limited and infrequent. CONCLUSION: Pulsed Dye Laser therapy is a highly effective and safe method used to selectively destroy warts without damaging the surrounding skin.

Pulsed Dye Laser Treatment of Vascular Lesions in Children
The Journal of Dermatologic Surgery and Oncology, 1993Co-Authors: Roy G. GeronemusAbstract:background. The flashlamp-pumped pulsed Dye Laser (577, 585 nm) with 300 to 450 μsecond pulsewidths has been demonstrated to effectively and safely treat portwine stains, telangiectases, and superficial hemangiomas in children. objective. The objective of this manuscript is to review the indications of the pulsed Dye Laser in the treatment of vascular lesions in children. conclusion. Pulsed Dye Laser treatment of port-wine stains can remove or lighten the lesions with multiple treatment sessions. Spider telangiectases respond with complete resolution, usually within one to two treatment sessions. Superficial hemangiomas respond quite easily and effectively with the pulsed Dye Laser, while a more variable response is noted in deeper hemangiomas, early proliferative lesions, and ulcerated hemangiomas. This procedure is safe with a low incidence of scarring and pigmentary alteration.
