Because the photosensitizer is preferentially absorbed by hyperproliferative tissue and the light source is directly targeted on the lesional tissue, photodynamic therapy achieves dual selectivity, minimizing damage to adjacent healthy structures. Patients should be thoroughly questioned concerning the use of any prescription drugs, over-the-counter medications, or herbal products and regarding any procedures that could increase the photosensitivity or penetration of MAL or ALA.

Occasionally, however, the patient may have persistent symptoms long after the allergen is gone or may have recurrent reactivations of the dermatitis when exposed to only the light source alone. However, subanalysis of the data suggested that a single session (without retreatment) may not be sufficient for AKs that are of moderate thickness. In this section focus, we highlight ACD and explore top relevant allergens, regional-based dermatitis presentations, topic-based dermatitis presentations and clinical tips and pearls for diagnosis and treatment. Elsevier, 2008. eBook. Patients who have never been treated with ALA photodynamic therapy can be started with a 30- to 60-minute incubation time if ALA is applied to broad areas. As sunscreen agents and topically applied NSAIDS are the major known allergens in PACD, a careful history of exposures is key to finding the causative agent.

The individual variability of phototoxic reactions seen following photodynamic therapy and the possibility of a severe phototoxic reaction (with erythema, a burning sensation, crusting, and vesicles) should be discussed in advance. Batchelor et al showed that a 48-hour application time was more accurate, and, since then, most photo-patch test protocols follow this 48-hour application schedule.13. The importance of using red versus blue light has not been thoroughly studied, but given that sebaceous glands are often located in the mid dermis, red light might be a better choice to target these glands.

[2, 3, 4, 5, 6, 7, 8]. 2003; 14(1):5-11. [25, 26, 27, 28, 29, 30, 31, 32] At present, topical ALA and MAL are the most promising photodynamic therapy agents for many dermatologic uses. [Medline]. The major limitation of topical photodynamic therapy is its depth of treatment, which appears to be mainly the result of the failure to achieve adequate drug penetration, rather than light penetration. It is probably underestimated because of the lack of patient access to photo-patch testing (PPT), the need for a high incidence of suspicion and confusion around which allergens to photo-patch test.5-7 In 2003, Warshaw et al8 found that only 65% of members of the American Contact Dermatitis Society (ACDS) routinely performed PPT. Patients should stay inside and avoid exposure to sunlight, bright artificial lights, or cold between ALA application and light exposure. /viewarticle/906683 However, in clinical practice, most physicians are currently using shorter (30-90 min) incubation times for the treatment of AK.

For enhanced penetration for BCC, use red light and not light of a shorter wavelength (eg, blue light, green light, daylight). 3. Light at a wavelength corresponding to a peak of the porphyrin excitation spectrum in tissues is used to most efficiently generate a therapeutic effect. 7:43. Physicians currently using ALA photodynamic therapy for the treatment of acne use a short incubation time of 30-60 minutes followed by light exposure, mostly from a Blu-U or an intense pulse light device. Physicians are also currently using light sources other than the FDA-approved Blu-U for the treatment of AK.
