Photodynamic therapy (PDT) is a technique that utilizes reactive oxygen species produced by a non-toxic dye or photosensitizer molecule in the presence of low intensity visible light to kill mammalian or microbial cells ((1)) . The advantages of PDT are numerous, it is a safe, non-invasive technique which yields effective therapeutic results ((2)) . Photodynamic therapy is not free of adverse effects. The most common one is pain during illumination. With the use of portable light sources to optimize the procedure and facilitate outpatient treatment, the concept of ambulatory PDT has emerged...

BACKGROUND: Photochemotherapy with psoralen and ultraviolet A (PUVA), with or without adjuvant interferon-α (IFN-α), is a first line therapy for early stage mycosis fungoides and other forms of cutaneous T-cell lymphoma (CTCL). However, the mechanism by which PUVA with IFN-α work in CTCL is poorly understood. PURPOSE: To develop a model to investigate the mechanisms of PUVA and PUVA with IFN-α in CTCL cells. METHODS: An in vitro model to study the molecular mechanisms of PUVA was created using two different CTCL cell lines, MyLa, which has functional p53, and HuT-78, in which p53 is inactivated due to a homozygous nonsense mutation...

Psoriasis continues to be a debilitating skin disease affecting 1-3% of the United States population. Although the effectiveness of several current biologic therapies have described this pathology as a IL-23, TNF-α and Th17-mediated disease, less invasive approaches are still in use and in need of refinement. One of these is the usage of narrow band-UVB (NB-UVB) therapy to deplete specifically intra-epidermal CD3(+) , CD4(+) and CD8(+) cells to clear psoriatic plaques. In order to improve NB-UVB therapy, we sought to determine whether skin pre-treatment with the TLR7 agonist imiquimod (IMQ) would help increase the efficiency of the former at resolving psoriatic plaques...

BACKGROUND/PURPOSE: There is strong evidence that topical sunscreens, designed to protect against ultraviolet radiation (UVR) induced erythema, decrease the amount of UVR to which the skin is exposed, but their effectiveness in reducing UVR-induced DNA damage in vivo has not been well quantified. METHODS: We systematically reviewed the published literature (1990-2015) to determine whether sunscreens prevent DNA damage in human skin when applied prior to UVR exposure...

Solar urticaria and polymorphous light eruption (PLE) are acquired idiopathic photosensitivity disorders, but each phenomenon is extremely different; one is an immediate reaction, and one is a delayed-type reaction. Phototesting is necessary not only for the diagnosis of these photosensitivity disorders but also for the determination of the action spectrum so that the patient can try to avoid the triggering wavelengths in ordinary life. Solar urticaria is unique in that the particular spectra that inhibit or enhance the reactions by action spectra are present in some cases...

Polypodium leucotomos (PL) exerts potent antioxidant, photo-protective and immune-modulatory activities. A reconstructed human epidermis (RHE) (Episkin) is a suitable model for the evaluation of acute UV-induced cell damage. No data regarding the photo-protective action of PL in this model are available. We evaluated the effects of PL on the prevention of UVB-induced cell damage assessing sunburn cells, CPD formation, p53, Ki-67, p21 expression, and Epidermal Growth Factor (EGF) production. RHE was incubated in standard conditions...

BACKGROUND/PURPOSE: There are no data comprehensively investigating the key beliefs and sun-protection behaviours in patients with actinic keratosis (AK). Our aim is to determine and correlate the AK perceptions and readiness to increase sun protection (RISP) behaviours. METHODS: AK patients' (n=200) demographics and clinical findings were recorded. Participants completed questionnaires (Illness Perception Questionnaire-Revised and RISP behaviours scales). RESULTS: The mean scores of giving up sunbathing of the patients aged <65 years, and giving up sunbathing and staying in the shade behaviours of females were higher...

BACKGROUND: Photodynamic therapy (PDT), using topical aminolevulinic acid (ALA), has been used for years to treat a variety of dermatologic conditions, including actinic keratosis, superficial basal cell carcinoma, and in situ squamous cell carcinoma. While there is a wide range of neoplastic and non-neoplastic skin diseases for which ALA-PDT is used in adults, there is a knowledge gap when it comes to its use in children. This review highlights what is currently known regarding the use and efficacy of this therapy in the pediatric population...

BACKGROUND: Ultraviolet A (UVA), one of the major components of sunlight, can penetrate the dermal layer of the skin and generate reactive oxygen species (ROS). It causes alterations in the dermal connective tissue and gene expression, inflammation, photoaging, and DNA damage. AIMS: Therefore, the harmful effects of UVA and strategies to reduce it have been consistently investigated. 23-Hydroxytormentic acid (23-HTA) has been demonstrated to improve drug-induced nephrotoxicity and exhibit several free radical scavenging effects with other molecules...

BACKGROUND: The incidence of melanoma has been rising worldwide. One possible reason for this is natural and artificial UV exposure. Only little data on actual consumer statistics from tanning studios and the usage of sunscreen are available. Therefore, it is difficult to describe trends for both and identify the impact of preventive measures. METHODS: To gain knowledge about the popularity of 'tanning bed' and 'sunscreen', normalized search volumes for both search queries were obtained from Google Trends for 11 countries between January 2004 and June 2016...

LETTER
Kelsie Riemenschneider, Jennifer G Powers
Minocycline is a tetracycline antibiotic that can induce hyperpigmentation and scarring of the skin, nails, mucous membranes, thyroid, teeth, bones, and heart valves. Minocycline-induced cutaneous hyperpigmentation consists of three types. Type I pigmentation occurs in areas of prior inflammation such as scars, and it is not thought to be dependent on treatment dose or duration. Type II and type III pigmentation, which occur on normal skin and sun-exposed skin, respectively, appear to be dose-related. This side effect can persist for years if not permanently despite treatment attempts, and definitive therapy does not exist...

BACKGROUND/PURPOSE: Rates of melanoma are rising in Hispanics in the United States. Excessive sun exposure in childhood increases the risk of melanoma in adulthood, and little is known about the factors motivating sun protection behaviors among Hispanic youth. METHODS: Correlates of sun protection were examined among Hispanic children residing in Los Angeles, California (N=1,891). Associations between multiple constructs (psychosocial, familial and cultural) and sun protection outcomes (use of sunscreen, protective clothing, and shade seeking/sun avoidance) were examined...

Porokeratosis (PK), initially described by Mibelli in 1893, is a skin disorder of epidermal keratinization. This disorder is clinically characterized by annular plaques with edges and atrophic centers, as well as histopathologically characterized by the presence of cornoid lamella. The etiology of this disease remains unknown. Several genes have been reported as causative genes, such as mevalonate kinase, phosphomevalonate kinase, mevalonate decarboxylase, and farnesyl diphosphate synthase. The four genes participate in the mevalonate pathway, which may be involved in the proliferation and differentiation of keratinocytes (1, 2)...
