OBJECTIVE The purpose of this clinical study was to evaluate the efficacy of an intense pulsed light (IPL) irradiator system for the treatment of port-wine stains (PWS) resistant to multiple pulsed dye laser (PDL) treatments. MATERIALS AND METHODS Fifteen PWS patients, who were previously found to be resistant to multiple PDL treatments, were treated four times with a second generation IPL sy...

Psoriasis can involve the skin, joints, and nails, either alone or in combination. Psoriasis of the nails can involve both the nail bed and nail matrix. The treatment of nail psoriasis largely depends on the severity of symptoms. The pulsed dye laser (PDL) recently has demonstrated efficacy in treating resistant plaque-type psoriasis and has been suggested as an alternative to conventional ther...

INTRODUCTION Several studies have reported laser treatment of Capillary Malformations (CMs) using systems other than pulsed dye lasers (PDL). Few, however, have compared different systems in the same patients. This study aimed to directly compare CM fading using five different systems. METHODS Eighteen previously PDL-treated patients were test-patched using the alexandrite, KTP, and Nd:YAG la...

OBJECTIVE Laser treatment of port-wine stain (PWS) might be improved using a deeply penetrating wavelength. METHODS PWSs in 17 patients were treated 3 times with a 595-nm pulsed dye laser (PDL) and a 1064-nm neodymium:yttrium-aluminum-garnet (Nd:YAG) laser. Fluences of 1.0, 0.8, and 0.6 times the minimum purpura dose (MPD) were used for Nd:YAG laser. Posttreatment biopsy specimens were taken....

BACKGROUND Keloids are abnormal wound responses characterised by excessive deposition of collagen and glycoprotein. They are both aesthetically and symptomatically distressing for most of the patients. There are reports of keloid management with pulsed dye laser (PDL), fractional carbon dioxide (CO2) laser and neodymium-doped yttrium aluminium garnet (Nd:YAG) laser individually and also in comb...

PURPOSE Although pulsed dye laser (PDL) treatment of port-wine stain (PWS) has long been proven safe and effective, incomplete clearance of these vascular malformations can be problematic. In addition, advanced PWS with deeper coloration and tissue hypertrophy can be particularly difficult to treat because of the superficial dermal penetration of 585- to 595-nm light. The purpose of this study ...

Laser treatment of vascular skin lesions is rapidly improving. Port wine stain (PWS) is one of the first lesions successfully treated with laser. The pulsed dye laser (PDL) has been developed on the concept of selective photothermolysis and has revolutionized PWS treatment. Even though the response is variable, substantial blanching can be obtained after several sessions. Greater selectivity an...

OBJECTIVE Cutaneous telangiectases are a characteristic and psychologically distressing feature of SSc. Our aim was to assess the efficacy of two light-based treatments: pulsed dye laser (PDL) and intense pulsed light (IPL). METHODS Nineteen patients with facial or upper limb telangiectases underwent three treatments with PDL and IPL (randomly assigned to left- and right-sided lesions). Outco...

I applaud Qin et al. for their publication, “Photodynamic therapy of port wine stains – a report of 238 cases”1. Such extensive experience with photodynamic therapy (PDT) for port wine stains (PWS) is impressive and I believe, unequaled in the Western world. In the United States and Europe, pulsed lasers and light sources, especially the pulsed dye laser (PDL; wavelengths = 585 or 595 nm) are t...

Background: Although cryotherapy is still the first-line therapy for solar lentigines, due to side effects such as post-inflammatory hyperpigmentation (PIH), especially in patients with darker skin types, pigment specific lasers should be considered as initial treatment. The aim of this study was to evaluate the efficacy and safety of cryotherapy in comparison with 595-nm pulsed dye laser (PDL)...
