BACKGROUND Port wine stains (PWS) affect 0.3-0.5% of both sexes of newborns, usually occurring on the face. OBJECTIVE To document safety and effectiveness of cryogen spray cooled, pulsed-dye laser at higher fluences than previously used to lighten facial PWS in infants < or =6 months, and establish that frequent treatment early in life yields better clearance than if delayed until later in li...

BACKGROUND AND OBJECTIVES Nonablative dermal remodeling is an evolving technology that has generated great interest among both laser surgeons and patients. Evidence indicates that dermal collagen formation is the key mechanism of action for the nonablative techniques. We studied, with ultrasound, new collagen formation after nonablative laser irradiation. METHODS Ten patients with facial rhyt...

BACKGROUND Nodular amyloidosis is a rare form of primary localized cutaneous amyloidosis which is characterized by single or multiple nodules located on the extremities, trunk, genitalia, or face. OBJECTIVE To determine the clinical and histologic response of nodular amyloidosis to pulsed dye laser treatment. METHODS Biopsy-proven amyloid nodules were treated with a 585-nm pulsed dye laser ...

Scars can manifest with cosmetic disfigurement, functional impairment, and discomfort which be particularly impactful in children adolescents. Laser therapy has been recently developed as a useful modality to improve both the appearance of scars status patients. Our study aims determine an association between ratings blind evaluators patient reported outcomes pediatric scar patients pre- post-t...

BACKGROUND AND OBJECTIVES Both the diagnosis and the treatment of lichenoid dermatosis are often difficult and can be time-consuming. There are now more and more publications about the use of laser systems--especially the flashlamp-pumped pulsed dye laser--in the treatment of inflammatory dermatoses, although the laser's exact mechanism of action in these cases is not yet clear. STUDY DESIGN/...

We demonstrate a new type of four-pass dye laser amplifier that can reduce the possibility of parasitic oscillation between optical components used in the amplifier. Pumping the amplifier with a 5.6-mJ Q-switched doubled Nd:YAG laser output, we obtain high-peak-power pulsed output of an incident cw narrow-bandwidth dye laser beam with a power gain greater than 2 x 10(6) . Subsequent amplificati...

Background: Many efforts are made to find new and more effective treatments for psoriasis. Intralesional 5-Fluorouracil (5-FU) +epinephrine is a cheap option which can be administered with long intervals. The effectiveness of Pulse Dye Laser (PDL) on psoriasis has been already assessed. We decided to evaluate the effectiveness of 5-FU+epinephrine and compare it to betamethasone and PDL.</...

BACKGROUND Multiple eccrine hidrocystomas are benign cystic lesions that pose a significant treatment challenge due to their facial location and tendency to scar after traditional surgical and other destructive modalities. METHODS A 585nm pulsed dye laser was used at fluences ranging 7.0 J/cm2 to 7.5 J/cm2 at 6- to 8-week intervals to treat multiple lesions on the face of a 54-year-old man. ...
