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 ski...

BACKGROUND Nonablative lasers are widely used for treatment of wrinkles, atrophic scars and acne. These lasers stimulate dermal remodelling and collagen production, but the early molecular stimulus for this is unknown. The mechanism of nonablative lasers in inflammatory acne is variously suggested to be damage either to sebaceous glands or to Propionibacterium acnes. Their effects on cytokine p...

Seventeen two-photon transitions for neon have been observed in the 580- 635 nm spectral region for use in the spectroscopic study of its higher excited levels, which are not accessible by one-photon absorption. To compare the two and one-photon absorption signals originating from the same lower level, an effort was made to record single-photon optogalvanic spectrum in the available wavele...

Current standard treatment of cutaneous lupus erythematosus (CLE) include sun protection, topical corticosteroids, and systemic treatment. Various non-medical alternative/adjunctive treatments have been reported such as cryotherapy, laser therapy. Several studies shown the efficacy pulsed dye (PDL) for discoid (DLE). Also there was a case report demonstrating fractional photothermolysis reminis...

Potential complications of IH include impairment of visual or respiratory function, ulceration, permanent anatomic distortion, dyspigmentation, and significant scarring. Haggstrom and colleagues reported that 24% of 1,058 patients with IH who were followed in a national registry developed complications. The most common area of involvement is the face, with 22.9% of facial hemangiomas developing...

Venous malformations are slow-flow vascular malformations present at birth, although they occasionally do not become clinically evident until several years later. They manifest clinically as soft, nonpulsatile masses of blue or violaceous color that compress easily on palpation. Their presence within the mouth is not uncommon and can be associated with bleeding, ulceration, pain, difficulty swa...

BACKGROUND Currently, 595 nm pulsed dye laser (PDL) therapy is offered as one of the effective treatments of port wine stains (PWSs). However, the efficacy of PDL differs in different populations. OBJECTIVE The purpose of the study was to investigate the efficacy, and related factors, of 595 nm PDL in the treatment of PWSs in Chinese patients with skin type III to IV. METHODS A total of 848...

BACKGROUND AND OBJECTIVES The 585-nm pulsed-dye laser and the 1,450-nm diode laser have been found effective for the treatment of mild-to-moderate inflammatory facial acne. This study was designed to evaluate the efficacy and safety of the combined treatment with the 595-nm pulsed-dye laser and the 1,450-nm diode laser for inflammatory facial acne. STUDY DESIGN/MATERIALS AND METHODS Fifteen p...

Background Port-wine stain (PWS) birthmarks currently are treated using a pulsed dye laser (PDL) combined with transient cooling of the epidermis. PDL treatment protocols utilize short pulses of light (585 or 595 nm wavelength) to heat selectively the microvasculature due to absorption by intravascular hemoglobin. Although most patients respond to PDL therapy, few experience complete removal of...

Because of its vascular selectivity, the flashlamp-pumped pulsed dye laser (585 nm) is efficacious in the treatment of vascular lesions and is successfully used for the treatment of port-wine stains and haemangiomas in children. Based on the encouraging results with these cutaneous vascular disorders, the cutaneous lesions of patients with lupus erythematosus (LE) have now also been treated wit...
