The penetration of 0.005% fluticasone propionate ointment in eyelid skin.

BACKGROUND: The use of corticosteroids to treat periorbital dermatoses carries significant risk of serious side effects such as glaucoma, cataracts, and blindness. Studies to assess levels of corticosteroid penetration in the eyelid are lacking. OBJECTIVE: We assessed corticosteroid penetration in eyelid skin in vitro to obtain information leading to the establishment of safer dosing regimens. METHODS: Fluticasone propionate ointment, 0.005%, was applied (approximately 2-5 mg/cm(2)) to samples of human eyelid skin, and penetration was assessed by using modified Franz diffusion cells. Drug concentration was determined at 12, 24, 36, and 48 hours after application by liquid chromatography tandem mass spectrometry. RESULTS: Only very small amounts of fluticasone propionate penetrated the skin (range, 0.618% +/- 0.339% to 1.467% +/- 0.695%). CONCLUSION: Further studies are warranted to examine the safety and efficacy of 0.005% fluticasone propionate ointment for the treatment of eyelid dermatoses.

All-trans-retinoic acid-induced scrotal ulcerations in a patient with acute promyelocytic leukemia.

Induction therapy with all-trans -retinoic acid has been shown to improve the outcome of patients with acute promyelocytic leukemia, although some side effects occur. Dry skin and lips are among the most common cutaneous side effects. We report a case of scrotal ulcerations induced by all-trans -retinoic acid in an American patient; to our knowledge this is the first such case reported.

Souvenir from the Hamptons - a case of cutaneous larva migrans of six months' duration.

Cutaneous larva migrans is a distinctive serpiginous eruption caused by a reaction to burrowing hookworms. The infection is usually self-limited, normally lasting 2-8 weeks, but may persist for more than a year if misdiagnosed. Biopsies of the creeping eruption rarely reveal an organism. Thus, it is important for the infection to be recognized clinically, so that effective treatment may begin. We found topical thiabendazole to be fast and effective in treating this case of cutaneous larva migrans of six months' duration.

Immunopathogenesis of scleroderma--evolving concepts.

Scleroderma, or systemic sclerosis, is a connective tissue disease which may affect various organ systems including skin, lungs, gastrointestinal tract, cardiovascular system and kidneys. While the etiology is not clear, it is currently believed that scleroderma may represent an autoimmune response to an unknown antigen. In this regard, there is evidence that both humoral and cellular immunity may play roles. The pathophysiology is complex and consists of three major features: (1) vascular damage; (2) mononuclear cellular infiltrates; and (3) massive deposition of newly synthesized connective tissue, mainly collagen. The major pathologic features of scleroderma and the roles of humoral and cellular immunity in its pathogenesis are reviewed and summarized.
