Validation of a non-contact technique for local skin temperature measurements.

Unlabelled: Here we propose to quantify local temperature variations using thermal imaging to assess the effect of dermatological lasers.

Objectives: To quantify the temperature raise induced by laser application and to differentiate the effects of a potassium titanyl phosphate (KTP) laser and an intense pulsed light (IPL).

Methods: A randomized comparative study was performed on 10 adult volunteers with symmetrical rosacea treated by KTP laser or IPL.

[Relationship between clinical findings of patients with bullous pemphigoid and antigens recognized by their circulating antibasement membrane zone antibodies].

Introduction: Clinical features and extent of bullous pemphigoid lesions differed widely among patients. The pathogenic role of anti-BPAG2 antibodies has been recently demonstrated. The aim of this study was to analyze the relationship between clinical features of bullous pemphigoid patients and the antigens recognized by their serum.

Clinical criteria for the diagnosis of bullous pemphigoid: a reevaluation according to immunoblot analysis of patient sera.

Background: We previously proposed a set of 4 clinical criteria for the diagnosis of bullous pemphigoid (BP) that consisted of age greater than 70 years, absence of atrophic scars, absence of mucosal involvement and absence of predominant bullous lesions on the neck and head. These results have been challenged because direct immunoelectron microscopy (IEM), which was used as the standard diagnostic criterion in our initial study, does not identify the different antigens of the basement membrane zone.

Objective: To reassess the validity of these clinical criteria for the diagnosis of BP using immunoblot analysis of patient sera as the main diagnostic criterion, in order to precisely identify the antigens recognized by patient sera.

[Intravascular papillary endothelial hyperplasia: multiple lesions appearing in the course of treatment with interferon beta].

Introduction: Intravascular papillary endothelial hyperplasia is a benign and rare vascular lesion. We report a case of multiple vascular lesions of the hand following 3 months treatment with beta-interferon injections for multiple sclerosis.

Observation: A 50 year-old man had multiple vascular nodules of the hands.
