BACKGROUND Eczematous skin changes overlying port-wine stains have been reported to improve with pulsed-dye laser (PDL) treatment. However, PDL has not as yet been evaluated for the treatment of atopic dermatitis (AD; eczema). AIM To evaluate in a controlled trial the effects and safety of PDL treatment in children with AD who had chronic localized lesions. METHODS Twelve children with loca...

BACKGROUND Pulsed dye laser (PDL) is the gold standard for treatment of port-wine stain (PWS) birthmarks but multiple treatments are required and complete resolution is often not achieved. Posttreatment vessel recurrence is thought to be a factor that limits efficacy of PDL treatment of PWS. Imiquimod 5% cream is an immunomodulator with antiangiogenic effects. OBJECTIVE We sought to determine...

introduction: solar lentigines are among commonest cosmetic problems. there are many topical therapies suggested to treat these lesions including cryotherapy, chemical peeling with tri chloro acetic acid (tca) and laser therapy with q-switched lasers as well as long pulsed lasers. considering possible treatment side effects (pih, scar) with cryotherapy and peeling in iranian patients (darker sk...

INTRODUCTION Acne vulgaris is a multifactorial disease of the pilosebaceous unit characterized by the development of inflammatory (papules, pustules, cysts) and/or non inflammatory lesions (open and closed comedones) that may progress to scars. The increase of bacterial resistances, adverse effects and teratogenicity of retinoids and lack of response to usual therapies have led to investigate n...

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...

Twenty years of laser dermatology has resulted in current technology which allows variable spot sizes, different wavelengths, and a variety of effective cooling devices. These developments have made the treatment of cutaneous pigmented and vascular lesions safe and efficacious by targeting selected chromophores while minimizing damage to the surrounding tissue. Vascular lesions are targeted by ...

OBJECTIVE To assess the comparative efficacy of energy treatments in resolving cherry angiomata. DESIGN Rater-blinded randomized controlled trial. SETTING Outpatient dermatology clinic in an urban referral academic medical center. PARTICIPANTS Fifteen healthy adults aged 21 to 65 years were enrolled. Two eligible individuals who were approached declined to participate, and no one enrolled...

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 The optimal parameters for treatment of leg telangiectasia with a pulsed laser are investigated. STUDY DESIGN/MATERIALS AND METHODS The Monte Carlo method is used to calculate the light penetration and absorption in the epidermis, dermis, and the ectatic blood vessel. Calculations are made for different diameters and depths of the vessel in the dermis. In addition, th...

BACKGROUND The pulsed dye laser (PDL) has long been used for treatment of erythematous and hypertrophic scars. Its effectiveness has been attributed in large part to its vascular-specificity. The vascular-specific potassium titanyl phosphate (KTP) laser has also been reported to be clinically effective for scars, but has not been compared to the PDL. OBJECTIVE To compare the safety and clinic...
