BACKGROUND: The commercial tanning industry has opposed efforts to educate the public on the risks of tanning as well as attempts to restrict minors' access to tanning services. Despite a paucity of supporting literature, statements from the tanning industry claiming that dermatologists routinely use in-office phototherapy for cosmetic treatments and refer patients to tanning salons have successfully derailed and defeated legislation in many states. OBJECTIVE: This study aims to evaluate dermatologist referrals for ultraviolet radiation for cosmetic and medical purposes via tanning beds or phototherapy, as well as their opinions on tanning, legislation, and ultraviolet radiation counseling practices...

Sulfur-substituted nucleobases (i.e. thiobases) are a prospective class of compounds for clinical and cosmetic topical phototherapies. Recent investigations of several thiobases have revealed the ultrafast and efficient population of reactive triplet states upon UVA irradiation and the subsequent generation of singlet oxygen in high yield. In this contribution, we examine the photosensitizing activities of three of the most promising thiobase derivatives discovered to date, 2,4-dithiothymine, 2,4-dithiouracil, and 2,6-dithiopurine...

The management of psoriatic disease in the human immunodeficiency virus (HIV)-positive population is challenging. The clinical course often is progressive and refractory; therefore, first- and second-line therapies including topical agents, phototherapy, and oral retinoids often are inadequate. Most other currently available systemic therapies for psoriatic disease are immunosuppressive, which poses a distinct clinical challenge. A comprehensive systematic review of the literature via a PubMed search of articles indexed for MEDLINE using the terms psoriasis and HIV and psoriatic arthritis and HIV combined with several systemic immunosuppressive agents yielded a total of 25 reported cases of systemic immunosuppressive therapies used to treat psoriatic disease in HIV-positive patients including methotrexate, cyclosporine, etanercept, adalimumab, infliximab, and ustekinumab...

Chemotherapy is an important treatment for malignant tumors; however, its efficacy and clinical application are limited by its side effects and drug resistance properties. Chemotherapy and phototherapy exhibit synergistic anti-tumor effects. In the present study, a carboxylated poly(amido-amine) (PAMAM) with low cytotoxicity was synthesized as a delivery nanocarrier for loading chemotherapeutic drugs, temozolomide (TMZ), and fluorescent dye indocyanine green (ICG). Hyaluronic acid (HA), which targets the CD44-overexpressing cancer cells, was modified on the nanocarrier surface to enhance the selective killing of melanoma cells...

Vitiligo has a substantial negative impact on quality of life in affected patients, especially those with involvement of the face. However, the current system can barely distinguish between specific patterns of facial involvement except for the segmental type when focusing only on facial lesions. We classified facial vitiligo into three distinct subtypes using cluster analysis based on facial topography (n = 473): centrofacial vitiligo (72.9%), panfacial vitiligo (18.0%), and hairline vitiligo (9.1%). Centrofacial vitiligo was the most common type and is thought to comprise the typical facial involvement of generalized vitiligo...

Therapeutic efficacy of glioblastoma multiforme (GBM) is often severely limited by poor penetration of therapeutics through blood-brain barrier (BBB) into brain tissues and lack of tumor targeting. In this regard, a functionalized upconversion nanoparticle (UCNP)-based delivery system which can target brain tumor and convert deep tissue-penetrating near-infrared (NIR) light into visible light for precise phototherapies on brain tumor was developed in this work. Methods : The UCNP-based phototherapy delivery system was acquired by assembly of oleic acid-coated UCNPs with angiopep-2/cholesterol-conjugated poly(ethylene glycol) and the hydrophobic photosensitizers...
