BACKGROUND This study was performed to assess the photothermal response of highly focused laser energy using infrared thermal imaging instrument to detect and assess the actual temperature distribution during flash lamp pumped pulsed dye laser (FLPPDL) treatment for port wine stain (PWS) patients and avoiding its complications. METHODS A retrospective review of 40 patients with PWS birthmark ...

BACKGROUND The current modality of choice for the treatment of Port-wine stains (PWS) is laser photocoagulation. Laser therapy for the treatment of PWS, especially with a pulsed dye laser (PDL), has been proven safe and effective; however, because penetration of the PDL is too shallow for an effective ablation of the blebs, treatment of blebbed PWS, using PDL, may be insufficient. OBJECTIVE W...

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...

BACKGROUND AND OBJECTIVES Many laser, light and energy emitting devices are utilized for skin rejuvenation. STUDY DESIGN/MATERIALS AND METHODS The clinical approach to multiple problems of photoaging are discussed and an algorithm for approach by problem is presented. RESULTS Clinical use of various modalities such as LED photomodulation, intense pulsed light, pulsed dye laser, KTP laser, r...

BACKGROUND AND OBJECTIVES Neither the pathogenesis of port wine stain (PWS) birthmarks nor tissue effects of pulsed dye laser (PDL) treatment of these lesions is fully understood. There are few published reports utilizing gene expression analysis in human PWS skin. We aim to compare gene expression in PWS before and after PDL, using DNA microarrays that represent most, if not all, human genes t...

BACKGROUND Port-wine stains (PWS) affect 0.3% to 0.5% of newborns and pulsed dye laser (PDL) remains the treatment of choice. Optimal treatment intervals have not been established. OBJECTIVE We sought to validate the optimal treatment intervals for the management of facial PWS with PDL. METHODS In all, 24 infants with facial PWS who received at least 5 treatments with the PDL at 2-, 3-, and...

Traumatic scars on skin covering areas of high movement, especially areas on the face, can be stressful for patients. We report two cases of traumatic scars that occurred on the chin, and that were successfully treated with a combined therapy of 595-nm pulsed dye laser (PDL) and intramuscular injection of botulinum toxin. After the treatment, good cosmetic results were achieved in both patients...

BACKGROUND AND OBJECTIVE Pulsed dye laser (PDL) treatment of cutaneous vascular lesions is associated with variable and unpredictable efficacy. Thus, alternative treatment modalities are needed. Previous in vitro and in vivo studies have demonstrated enhanced selective vascular destruction with benzoporphyrin derivative (BPD) monoacid ring A photodynamic therapy (PDT) followed immediately by PD...

An efficient method for generation of high energy pulsed ir light between 0.9 and 1.5 ltm is described. The technique uses difference frequency mixing of pulsed, visible dye and Nd:YAG laser light in a 10 mm long BBO crystal. Quantum efficiencies of up to 23% and ir pulse energies up to 4.5 mJ are demonstrated. The low shot-to-shot fluctuations of difference frequency generation in BBO make thi...

BACKGROUND To our knowledge, no systematic analysis of nonablative laser therapy has been performed. OBJECTIVE To alter the parameters (fluence, spot size, pulse duration, and use of cooling spray) for the pulsed dye laser to determine the precise settings that would yield the most favorable dermal remodeling in a porcine model. METHODS Research was conducted in an animal laboratory at Alba...
