Hailey-Hailey disease successfully treated with vitamin D oral supplementation.

Hailey-Hailey disease (HHD) also known as familial benign chronic pemphigus is a rare autosomal dominant genodermatosis. HHD treatment is often not satisfactory and hence, various modalities of treatment have been tried. We describe the case of a 37-year-old woman with a 2 years history of macerated erythematous plaques along with erosions, fissures, and crusts located on axillae and submammary areas, successfully treated with only oral supplementation of vitamin D (800 I.

Topical delivery of active principles: the field of dermatological research.

To be effective an active drug or principle must cross the stratum corneum barrier; this process can be influenced to obtain better functional and therapeutical effects. In spite of the wide variety of the methods studied in order to improve the transdermal transfer to obtain systemic effects, the applicability is limited in this field. Attention to the epidermal barrier and penetration of active principles has been reported mostly in studies concerning dermocosmetics.

Oral terbinafine in the treatment of multi-site seborrhoic dermatitis: a multicenter, double-blind placebo-controlled study.

Seborrheic dermatitis (SD) is a common disorder for which no satisfactory curative treatment exists. Preliminary studies suggest that terbinafine may be effective. The efficacy and tolerability of oral terbinafine was evaluated in multi-site SD in a randomized, double-blind, placebo-controlled study.

Intradermal drug delivery by low-frequency sonophoresis (25 kHz).

Unlabelled: Ultrasound waves (US) have been proposed to facilitate the absorption of active compounds (transdermal delivery) stimulating some disaggregation of the horny layer and promoting convective movements within the epidermis. Drugs used for alopecia areata, melasma, and lentigo, although proved effective, have limited effects resulting from only partial penetration into the skin. This study has evaluated the efficacy of low-frequency sonophoresis (LFS) at 25 kHz produced by a sonicator apparatus for treatment of alopecia areata, melasma, and solar lentigo.

In vitro effect of 5-aminolaevulinic acid plus visible light on Candida albicans.

Photodynamic therapy, currently used as an alternative technique for the treatment of superficial non-melanoma skin cancers, has been employed in vitro to kill different species of microorganisms. Here the development of Candida albicans colonies has been measured after application of 5-aminolaevulinic acid (ALA) plus visible light (VIS) irradiation. C.
