BACKGROUND AND OBJECTIVE Port wine stains (PWS) are heterogeneous vascular malformations that can be treated with vascular-selective pulsed dye lasers (PDL). Hypertrophic PWS, especially in adults, are consistently less responsive to PDL. Furthermore, many PWS that respond well initially to PDL treatment may reach a response plateau, becoming unresponsive to further PDL treatments, a phenomenon...

INTRODUCTION Pulsed dye laser (PDL) has been used to treat acne lesions and scar erythema by interrupting superficial vasculature. Salicylic acid chemical peels are employed chiefly due to their lipophilic, comedolytic, and anti-inflammatory properties. Although studies have looked at peels and laser therapy independently in acne management, we examined these treatments in combination. Our prim...

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...

Acne is a common skin condition that can lead to significant scarring and psychological disturbance. The existing oral and topical anti-acne medications are limited by efficacy, adverse effects and patients' compliance. Lasers or light sources are explored as therapeutic options for acne. Light treatment targets the function of the pilosebaceous glands and reduction of Propionibacterium acnes t...

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...

Fujikura has achieved an output power of 30 W from a Q-switched pulsed fiber laser with a pulse width about 100 ns for the first time in the world. Following the achievement, we commercialized a 70 W output pulsed fiber laser . In the article, we describe our activities on high-power pulsed fiber lasers, and introduce our 70 W output products. Fujikura’s advanced and original functions of pulse...

The bone ablation characteristics of five infrared lasers, including three pulsed lasers (Nd:YAG, lambda = 1,064 micron; Hol:YSGG, lambda = 2.10 micron; and Erb:YAG, lambda = 2.94 micron) and two continuous-wave lasers (Nd:YAG, lambda = 1.064 micron; and CO2, lambda = 10.6 micron), were studied. All laser ablations were performed in vitro, using moist, freshly dissected calvarium of guinea pig ...
