BACKGROUND Topical silicone gel sheeting has been used for more than 20 years to help reduce the size of hypertrophic scars and keloids. Its clinical efficacy and safety is well established. OBJECTIVE To determine whether topical silicone gel sheeting can be used to prevent hypertrophic scars and keloids from forming following dermatologic skin surgery. METHODS Patients undergoing skin surg...

Chronic actinic dermatitis is a chronic photosensitivity disorder characterized by severe eczematous lesions on sun-exposed skin areas. We report a case of chronic actinic dermatitis presenting with leonine facies and secondary adrenal insufficiency, which was successfully treated with topical tacrolimus. The facial lesions dramatically improved after sun avoidance and topical tacrolimus applic...

OBJECTIVES To evaluate the comparative efficacy and tolerability of topical calcipotriol in the treatment of mild to moderate chronic plaque psoriasis. DESIGN Quantitative systematic review of randomised controlled trials. SUBJECTS 6038 patients with plaque psoriasis reported in 37 trials. MAIN OUTCOME MEASURES Mean difference in percentage change in scores on psoriasis area and severity ...

Psoriasis is a chronic inflammatory skin disease mediated by dysregulated auto-reactive immune system. In this study, in order to confirm and further extend the pharmacological basis of topical steroids in psoriasis therapy, we investigated the effect of betamethasone ointment on imiquimod (IMQ)-induced skin inflammation in mice. In BALB/c mice, topical IMQ at the dose of 250 µg each on both si...

Neat N-methyl-2-pyrrolidone (NMP) rapidly penetrated into the skin of male Sprague-Dawley rats after in vivo and in vitro topical application. At the two topical doses tested in vivo, no steady state was observed. The maximal absorption fluxes were 10 and 20 mg/cm(2)/h for 20 microl/cm(2) and 40 microl/cm(2), respectively. Similar results were observed after in vitro topical application of neat...

Semisolid preparations for external application to skin have gained much demand, since it is easily absorbed through the skin layers. Many novel topical dosage forms have been discovered, among which organogels appears to play an important role. Organogels are thermodynamically stable, biocompatible, isotropic gel, which not only give localised effect, but also systemic effect through percutane...
