To determine and compare the safety and efficacy of broad area photodynamic therapy with aminolevulinic acid (ALA-PDT) following topical retinoid pre-treatment vs ALA-PDT with occlusion on...
Photodynamic therapy is an effective treatment for actinic keratoses. In the United States topical aminolevulinic acid (ALA) is approved as a photosensitizing agent for this treatment, and...
Photodynamic therapy technique (PDT) is a conventional technique which is performed applying the product under occlusion lesions, let it incubate for 3 hours and then exposed skin to a lig...
Comparison of treatment efficacy and safety of pretreatment with ablative fractional laser versus microdermabrasion combined with large-area photodynamic therapy with methyl aminolevulinat...
To evaluate a possible prophylactic efficacy of photodynamic therapy on the incidence of non-melanoma skin cancer, actinic keratoses, warts and keratoses in recently organ transplanted rec...
Photodynamic therapy (PDT) is an effective therapy treating photodamaged areas with multiple actinic keratoses (AK). Still pain during therapy is one of the most challenging obstacles for patients. Th...
Photodynamic therapy (PDT) can be used to treat large fields of actinic keratoses (AKs) with high clearance rates. A notable downside is the amount of pain that accompany the treatment. This study aim...
It is important to collect data about the risk of transformation of an actinic keratosis (AK) lesion into squamous cell carcinoma (SCC) after a single photodynamic therapy (PDT) with 5-ALA patch for a...
Photodynamic therapy (PDT) is an effective intervention for actinic keratosis (AK) and field-cancerization. Ablative fractional laser may facilitate the delivery of photosensitizers and thereby improv...
Cutaneous field cancerization arises due to UV-induced carcinogenesis of a "field" of subclinically transformed skin and actinic keratoses (AKs) with a tendency to progress and recur. Commonly used tr...
The purified component of HEMATOPORPHYRIN DERIVATIVE, it consists of a mixture of oligomeric porphyrins. It is used in photodynamic therapy (HEMATOPORPHYRIN PHOTORADIATION); to treat malignant lesions with visible light and experimentally as an antiviral agent. It is the first drug to be approved in the use of PHOTODYNAMIC THERAPY in the United States.
A complex mixture of monomeric and aggregated porphyrins used in the photodynamic therapy of tumors (HEMATOPORPHYRIN PHOTORADIATION). A purified component of this mixture is known as DIHEMATOPORPHYRIN ETHER.
Preliminary cancer therapy (chemotherapy, radiation therapy, hormone/endocrine therapy, immunotherapy, hyperthermia, etc.) that precedes a necessary second modality of treatment.
Light-induced change in a chromophore, resulting in the loss of its absorption of light of a particular wave length. The photon energy causes a conformational change in the photoreceptor proteins affecting PHOTOTRANSDUCTION. This occurs naturally in the retina (ADAPTATION, OCULAR) on long exposure to bright light. Photobleaching presents problems when occurring in PHOTODYNAMIC THERAPY, and in FLUORESCENCE MICROSCOPY. On the other hand, this phenomenon is exploited in the technique, FLUORESCENCE RECOVERY AFTER PHOTOBLEACHING, allowing measurement of the movements of proteins and LIPIDS in the CELL MEMBRANE.
A compound produced from succinyl-CoA and GLYCINE as an intermediate in heme synthesis. It is used as a PHOTOCHEMOTHERAPY for actinic KERATOSIS.
