Epidermal Fluence Threshold Determination by Real-Time Melanin Measurements.

Background And Objective: Epidermal preservation is essential during laser treatment for vascular, hair, and benign pigment dyschromias. Epidermal tolerance is determined by epidermal melanin content, fluence, pulse width, wavelength, skin cooling, and spot size. The authors' objective was to determine the maximum epidermal tolerance for the long-pulse alexandrite 755 nm and the long-pulse neodymium-doped yttrium aluminum garnet (Nd:YAG) 1064-nm lasers for varying epidermal melanin content.

Incidence of and Risk Factors for Skin Cancer in Organ Transplant Recipients in the United States.

Importance: Skin cancer is the most common malignancy occurring after organ transplantation. Although previous research has reported an increased risk of skin cancer in solid organ transplant recipients (OTRs), no study has estimated the posttransplant population-based incidence in the United States.

Objective: To determine the incidence and evaluate the risk factors for posttransplant skin cancer, including squamous cell carcinoma (SCC), melanoma (MM), and Merkel cell carcinoma (MCC) in a cohort of US OTRs receiving a primary organ transplant in 2003 or 2008.

Defining the Absorption Spectrum of the Skin After Application of a Popular Sunless Tanner, Dihydroxyacetone, Using Re ectance Photospectrometry.

Dihydroxyacetone (DHA) is a popular ingredient in sunless tanner and lotions. We sought to measure the absorption spectrum of hu- man skin after application of DHA. A male in his 30's applied DHA to one underarm once daily for seven days.

Cutaneous siderosis secondary to intramuscular iron dextran treated with 755 nm Q-switched alexandrite laser: A case report.

Background: Cutaneous siderosis is accumulation of iron in the dermis and the subcutaneous tissue secondary to extravasation of an intramuscular or intravascular iron injection. It presents as varying shades of brown macules with no distinct contours. The hyperpigmentation is permanent without treatment.

Treatment of acral persistent papular mucinosis using an Erbium-YAG laser.

Background And Objectives: Acral persistent papular mucinosis (APPM) is a rare condition with persistent flesh colored papules on the hands and extensor wrists. The authors aim to present a novel treatment option for this condition.

Patients And Methods: A female with APPM was treated using a 2940 nm Erbium-YAG laser with a 1 mm spotsize defocused to 2-3 mm with settings of 200-300 mJ until the lesion was flush with the surrounding skin.

Genital psoriasis is associated with significant impairment in quality of life and sexual functioning.

Background: Genital involvement has significant psychosexual implications for psoriasis patients.

Objective: This study was designed to ascertain factors associated with the development of genital psoriasis and its impact on quality of life and sexual functioning.

Methods: This was an observational, multicenter study of 354 consecutive psoriasis patients.
