Efficacy of lidocaine 7 %, tetracaine 7 % self-occlusive cream in reducing MAL-cPDT-associated pain in subjects with actinic keratosis: A randomized, single-blind, vehicle-controlled trial (The "3P-Trial").

Introduction: Conventional photodynamic therapy (cPDT) is considered a very effective treatment of actinic keratosis (AK) lesions. However, its use is limited by the fact that this procedure could be very painful. The use of topical anesthetics such as tetracaine or lignocaine/prilocaine has shown disappointing results in term of pain reduction.

Peristomal allergic contact dermatitis caused by ostoma pastes and role of Gantrez ES-425.

Background: Peristomal allergic contact dermatitis is an emerging problem and contact sensitization is probably more common than previously thought. Our objective was to identify sensitization to the most common topical equipment for ostomy in patients with history of peristomal dermatitis.

Methods: Twenty-six patients with suspected peristomal contact dermatitis were patch tested with our standard series and with products for stoma care (adhesive pastes, powders, adhesive skin barriers).

Radiodermatitis after spinal arteriovenous fistula embolisation.

We report acute radiation dermatitis on a patient's back and left arm, which developed 4 weeks after endovascular embolisation of a spinal arteriovenous malformation. Vesciculation and erosions were followed by a gradual re-epithelisation of the skin resulting in rectangular hyperpigmented patches that resolved almost completely within 1 month. Fluoroscopic radiodermatitis has been reported with more frequency over the past decades because of the rise in duration and number of procedures performed under fluoroscopic guidance.

Daylight photodynamic therapy with methyl-aminolevulinate for the treatment of actinic cheilitis.

Actinic cheilitis (AC) is a common premalignant condition that requires an effective treatment to reduce the risk of malignant transformation. Photodynamic therapy (PDT) has been recently added to the armamentarium available for AC treatment. Daylight PDT (D-PDT) is a novel PDT modality in which the activation of the topical photosensitizer is induced by the exposure to natural daylight instead of artificial light sources without preliminary occlusion.
