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.

[Photoaggravated contact allergy and contact photoallergy caused by ketoprofen: 19 cases].

Introduction: Between September 1994 and September 1999, we observed 19 cases of photoaggraved contact allergy or contact photoallergy to ketoprofen (non steroidal anti-inflammatory derived from arylpropionic acid). We present a clinical and photobiological retrospective study of these 19 cases with investigation of cross-reactivity between benzophenone-containing molecules.

Patients And Methods: On clinical level, we investigated the type of eruption, the delay of appearance, the initial area of eruption and areas of diffusion.

Sweet's syndrome associated with retinoic acid syndrome in a patient with promyelocytic leukemia.

We report a case of Sweet's syndrome associated with retinoic acid syndrome in a patient with acute promyelocytic leukemia treated with all- trans retinoic acid (ATRA). Sweet's syndrome appeared on day 6 of ATRA therapy for promyelocytic leukemia. It was associated with a mild retinoic acid syndrome, an inflammatory syndrome occurring in 25% of patients treated with ATRA and characterized by features of capillary leakage with systemic inflammatory signs.

Prolonged photosensitivity following contact photoallergy to ketoprofen.

We report the third case of prolonged photosensitivity secondary to contact photoallergy to topical ketoprofen, a 2-arylpropionic acid derivative. The patient suffered from persistent photosensitivity for more than 1 year after the withdrawal of ketoprofen with recurrent eruptions on sun-exposed skin areas. This photosensitivity was associated with a persistent decrease in polychromatic and UVA minimal erythemal doses.

[Multiple cutaneous reticulohistiocytosis].

Background: Multicentric reticulohistiocytosis is a non Langerhans cell histiocytosis. This rare disease is characterized by cutaneous papules and nodules and a destructive polyarthritis; multisystem involvement may occur. Multiple and diffuse cutaneous reticulohistiocytosis have been more rarely reported.

Delayed-hypersensitivity granulomatous reaction induced by blepharopigmentation with aluminum-silicate.

Blepharopigmentation has been introduced during the last decade as a technique for creating a permanent line along the eyelid margin, thus simulating a cosmetic eyeliner. Complications related to this procedure are mostly reported in the opthalmologic literature describing infectious, allergic, or technical problems. We report a case of a woman who underwent blepharopigmentation with aluminum-silicate and in whom a delayed hypersensitivity granulomatous reaction developed.
