Four identification tests, proposed in addition to conventional methods, were evaluated with 320 fermentative nonlipophilic Corynebacterium strains: growth at 20 degrees C, glucose fermentation at 42 degrees C, alkalinization of sodium formate, and acid production from ethylene glycol. These tests were highly discriminant. Corynebacterium amycolatum displayed a unique profile, allowing it to be...

BACKGROUND Human T-cell lymphotropic virus type 1 (HTLV-1) infection can increase the risk of developing skin disorders. This study evaluated the correlation between HTLV-1 proviral load and CD4(+) and CD8(+) T cells count among HTLV-1 infected individuals, with or without skin disorders (SD) associated with HTLV-1 infection [SD-HTLV-1: xerosis/ichthyosis, seborrheic dermatitis or infective der...

BACKGROUND/OBJECTIVES The use of emollients is widely recommended for the management of atopic dermatitis (AD), especially between flares. An imbalance of skin microflora is suspected of playing a key role in exacerbations of AD. Our aim was to evaluate the effect of a new emollient balm on clinical parameters (SCORing Atopic Dermatitis [SCORAD], xerosis, pruritus), skin barrier function (trans...

INTRODUCTION Urea is an organic compound that has been used clinically for dermatological diseases for more than a century. Urea is a potent emollient and keratolytic agent, making urea an effective monotherapy for conditions associated with dry and scaly skin. A systematic review of the literature is needed to provide clinicians with evidence-based applications of urea in the treatment of derm...

Other disorders represent supervening complications in an already treated DM patient. OBJECTIVE To review the information about dermocosmetic care products and their appropriate use in the management and prevention of dermatoses ...

We report the cutaneous side effects of Iressa (ZD1839), a new anti-cancer agent that acts by inhibiting epidermal growth factor receptor signal transduction. The most common cutaneous adverse effect was the development of an acneiform eruption on the face, anterior trunk and back (39%). The second most common side effect was xerosis or desquamation of the face, body or distal parts of the fing...
