Reactive oxygen species can be generated by daily exposure of the skin to ultraviolet light and may cause some subchronic and chronic skin disorders. The aim of this study was to investigate a possible preventive role of alpha-tocopherol acetate (ATA) on ultraviolet B (UVB) induced peroxidation by assessing lipid peroxide (LPO) levels and activity of reactive oxygen scavenging enzymes including...

REVIEW QUESTION/OBJECTIVE The objective of this systematic review is to synthesize the best available research evidence to determine the risk of skin cancer in patients on long-term use of topical corticosteroids. Specifically the review question is: In people using long-term (regular use over one month) topical corticosteroids, what is the risk of developing skin cancer (clinically or histolog...

PURPOSE To report a case of atopic eyelid disease treatment using topical tacrolimus in a patient with open-angle glaucoma following corticosteroid discontinuation. DESIGN Interventional case report. METHODS A 59-year-old white man with a history of treated open-angle glaucoma (latanoprost 0.005%) was referred to our department for atopic eyelid disease. The patient had received previous tr...

INTRODUCTION Crystallization of actives in skin following topical application was suggested by studies in the 1950s and 1960s but is poorly understood. In contrast, the problem of crystallization of actives on skin and in transdermal formulations has been known for many years. AREAS COVERED With respect to crystallization in skin, this review describes early reports of a skin 'reservoir' and ...

The aim of the present study was to compare the effectiveness and the safety of different topical agents (glycolic acid, mandelic acid, and grape juice acid mixture) in skin exfoliation by objective instrumental methods. To evaluate the exfoliating effects of these substances, a new experimental in vivo protocol based on DHA (dihydroxyacetone)-induced skin pigmentation was used. Skin acceptabil...

The purpose of this work was to explore the feasibility of ethosomes for improving the antiarthritic efficacy of tetrandrine by topical application. It was found that tetrandrine was a weak base (pK(a) = 7.06) with pH-dependent partition coefficient. The spherical-shaped ethosomes were prepared by pH gradient loading method. Ex vivo permeation and deposition behavior demonstrated that the drug ...

PROSPECTIVE TRIAL COMPARING TOPICAL STEROID APPLICATION TO WET VERSUS DRY SKIN IN CHILDREN WITH ATOPIC DERMATITIS. Lucinda S. Liu, Yanna Kang, and Richard J. Antaya. Department of Dermatology, Yale University School of Medicine, New Haven, CT. The aim of this study was to determine whether “soak and smear,” a technique where hydration via a 10-minute soak in lukewarm plain water followed by top...

BACKGROUND Skin atrophy is a common manifestation of aging and is frequently accompanied by ulceration and delayed wound healing. With an increasingly aging patient population, management of skin atrophy is becoming a major challenge in the clinic, particularly in light of the fact that there are no effective therapeutic options at present. METHODS AND FINDINGS Atrophic skin displays a decrea...

Skin tests to various common antigens, dinitrochlorobenzene, and 5-fluorouracil (5-FU) were performed on patients being treated for cutaneous neoplasms with topical 5-FU cream. Eleven of 15 patients tested both before and after therapy converted from skin test negative to positive with respect to 5-FU. This conversion correlated with positive dinitrochlorobenzene skin tests and therapeutic cure...
