INTRODUCTION: Phototherapy with visible light is gaining interest in dermatological practice. Theoretically, blue light could induce biological effects comparable to ultraviolet A (UVA) radiation. OBJECTIVES: To study the effects of blue light on normal skin in terms of photodamage, skin ageing and
BACKGROUND: As different tissue types have distinct capabilities to accumulate protoporphyrin IX, fluorescence diagnosis with aminolevulinic acid-induced porphyrins (FDAP) could be used to discriminate between different types of tissue. Previous results demonstrated higher fluorescence ratios in squ
BACKGROUND: Psoriasis lesions accumulate protoporphyrin IX (PpIX) with a variable distribution within plaques due to variations in hyperkeratosis causing differences in penetration of cream or light. Objectives: To study the effects of different keratolytic pretreatments in PpIX-induced fluorescence
INTRODUCTION: Since actinic keratoses (AKs) often appear in areas with field cancerization, photodynamic therapy (PDT) may have significant advantages over the standard treatment options. Objectives: Clinical efficacy of PDT with topical methyl aminolevulinate (MAL-PDT) in field cancerization was ev
BACKGROUND: Narrow-band ultraviolet (UV) B phototherapy is an effective treatment for psoriasis. However, there is considerable variability in the number of treatment sessions needed to achieve psoriasis clearance. While several clinical and treatment-related factors predict time to clearance, the e
BACKGROUND: In photodynamic therapy the endogenous photosensitizer protoporphyrin IX (PpIX) is synthesized following topical application of aminolaevulinic acid (ALA). However, different tissues have distinct PpIX-accumulating properties, due to differences in penetration of ALA through the stratum
Electroporation of dendritic cells (DC) with mRNA encoding tumor-associated antigens (TAA) for cancer immunotherapy has been proved efficient and clinically safe. It obviates prior knowledge of CTL and Th epitopes in the antigen and leads to the presentation of multiple epitopes for several HLA alle
BACKGROUND: Ultraviolet (UV) B phototherapy is an established treatment option for psoriasis. The optimum dosage regimen still has to be determined. Within-subject comparisons do not take into account the systemic effects of UVB phototherapy. The area of the body treated with low-dose UVB may benefi
