BACKGROUND Hyperhomocysteinaemia is a well-known risk factor for cardiovascular diseases. Patients with severe chronic plaque psoriasis have a higher risk of death due to arterial and/or venous thrombosis. OBJECTIVES To investigate the relationship among plasma homocysteine and folate levels and severity of chronic plaque psoriasis in a selected cohort of(More)
Reflectance confocal microscopy (RCM) is a novel noninvasive technique for "in vivo" examination of the skin. In a confocal microscope, near- infrared light from a diode laser is focused on a microscopic skin target. As this light passes between cellular structures having different refraction indexes, it is naturally reflected, and this reflected light is(More)
The growing resistance against antifungal drugs has renewed the search for alternative treatment modalities, and antimicrobial photodynamic therapy (PDT) seems to be a potential candidate. Preliminary findings have demonstrated that dermatophytes and yeasts can be effectively sensitized in vitro and in vivo by administering photosensitizers (PSs) belonging(More)
BACKGROUND Mycosis fungoides (MF) is the most common primary cutaneous T-cell lymphoma (CTCL). Unilesional MF is characterized by a limited involvement of the skin and a chronical, though indolent course. If lesions are refractory to topical steroids, therapies such as localized chemotherapy, photochemotherapy and radiotherapy are available. However, they(More)
Photodynamic therapy (PDT) is a two-step therapeutic technique in which the topical or systemic delivery of photosensitizing drugs is followed by irradiation with visible light. Activated photosensitizers transfer energy to molecular oxygen, generating reactive oxygen species (ROS). The subsequent oxidation of lipids, amino acids and proteins induces cell(More)
BACKGROUND Findings of in vitro studies have demonstrated that dermatophytes and yeasts can be effectively photosensitized after topical delivery of 5-aminolevulinic acid (ALA). This procedure, called photodynamic therapy (PDT), seems to lack mutagenic activity and hazard of selection of drug-resistant strains. METHODS Twenty percent ALA preparation in(More)
BACKGROUND Photodynamic therapy (PDT) with methyl aminolaevulinate (MAL) is an approved noninvasive treatment option for basal cell carcinoma (BCC). In vivo reflectance confocal microscopy (RCM) is a noninvasive imaging technique that has proved useful for in vivo real-time cytomorphological analysis of BCC cells infiltrating the epidermis. OBJECTIVES  (More)
BACKGROUND Photodynamic therapy (PDT) with methylaminolaevulinate (MAL) is an approved noninvasive treatment option for actinic keratosis and Bowen's disease (BD), two precursors of invasive squamous cell carcinoma (SCC). OBJECTIVES To assess efficacy, prognostic features, tolerability and cosmetic outcome of MAL-PDT for the treatment of BD and SCC. (More)
BACKGROUND AND OBJECTIVE Photodynamic therapy (PDT) using aminolevulinic acid (ALA) has been previously investigated in the treatment of photodamaged skin. The aim was to assess efficacy and tolerability of methylaminolevulinate (MAL) as a substitute for ALA in PDT treatment of actinic keratosis (AK) and photoaging. STUDY DESIGN/MATERIALS AND METHODS(More)
BACKGROUND Studies assessing the association between coeliac disease (CD) and psoriasis show conflicting results. OBJECTIVE To assess in the primary care setting the prevalence of CD in patients with psoriasis and the response to a gluten-free diet (GFD) in subjects with psoriasis and CD. METHODS We enrolled 218 patients with psoriasis and 264 controls.(More)
