Definitions and outcome measures for bullous pemphigoid: Recommendations by an international panel of experts

Our scientific knowledge of bullous pemphigoid (BP) has dramatically progressed in recent years. However, despite the availability of various therapeutic options for the treatment of inflammatory diseases, only a few multicenter controlled trials have helped to define effective therapies in BP. A major obstacle in sharing multicenter-based evidences for therapeutic efforts is the lack of generally accepted definitions for the clinical evaluation of patients with BP. Common terms and end points of BP are needed so that experts in the field can accurately measure and assess disease extent, activity, severity, and therapeutic response, and thus facilitate and advance clinical trials. These recommendations from the International Pemphigoid Committee represent 2 years of collaborative efforts to attain mutually acceptable common definitions for BP and proposes a disease extent score, the BP Disease Area Index. These items should assist in the development of consistent reporting of outcomes in future BP reports and studies. © 2011 by the American Academy of Dermatology, Inc

Iterative Structure-Based Peptide-Like Inhibitor Design against the Botulinum Neurotoxin Serotype A

The botulinum neurotoxin serotype A light chain (BoNT/A LC) protease is the catalytic component responsible for the neuroparalysis that is characteristic of the disease state botulism. Three related peptide-like molecules (PLMs) were designed using previous information from co-crystal structures, synthesized, and assayed for in vitro inhibition against BoNT/A LC. Our results indicate these PLMS are competitive inhibitors of the BoNT/A LC protease and their Ki values are in the nM-range. A co-crystal structure for one of these inhibitors was determined and reveals that the PLM, in accord with the goals of our design strategy, simultaneously involves both ionic interactions via its P1 residue and hydrophobic contacts by means of an aromatic group in the P2′ position. The PLM adopts a helical conformation similar to previously determined co-crystal structures of PLMs, although there are also major differences to these other structures such as contacts with specific BoNT/A LC residues. Our structure further demonstrates the remarkable plasticity of the substrate binding cleft of the BoNT/A LC protease and provides a paradigm for iterative structure-based design and development of BoNT/A LC inhibitors

Herpes gestationis: two case reports.

Herpes gestationis (pemphigus gravidarum, pemphigoid gestationis) is a rare specific dermatosis of pregnancy with the onset in second trimester and worsening in third trimester of gestation. The onset of herpes gestationis has also been described in second trimester, and in early postpartal period. Other dermatoses of pregnancy include prurigo gestationis (besnier), pruritus gravidarum, impetigo herpetiformis, and polymorphic eruptions of pregnancy. On differential diagnosis, bullosus pemphigoid, papules and plaques of pregnancy, dermatitis herpetiformis, drug eruptions, erythema multiforme, and pemphigus vulgaris should be considered. Two patients with verified herpes gestationis are presented. In one patient, the illness developed after delivery, and in the other one four months before conception. The diagnosis of herpes gestationis was made on the basis of clinical features, direct immunofluorescence, and histopathologic findings

Interest of the association retinaldehyde/glycolic acid in adult acne

Topical retinoids have been successfully used in the treatment of acne vulgaris but may induce irritation when used twice daily. The association of retinaldehyde (RAL) with glycolic acid (GA) have complementary activities, which could be of interest for adult women with acne because of a better tolerance/efficacy ratio. The aim of this study was to evaluate the tolerance and the efficiency of RAL (0.1%)/GA (6%) in adult women with acne when used alone or in combination with their usual acne products except retinoids
