The widespread variety and popularity of mobile apps demonstrate a great potential to expand the practice and delivery of dermatologic care.

Participants: All nations with legislation regarding access to indoor tanning found through web-based Internet search. Main Outcome Measures: Number of nations with legislation and changes to laws regarding access to indoor tanning since 2003. Results: The number of countries with nationwide indoor tanning legislation restricting youth 18 years or younger increased from 2 countries in 2003 to 11 countries in 2011. Six states or territories in Australia restricted indoor tanning in all minors; a province and a region in Canada implemented youth tanning laws; and 8 states, in addition to 3 preexisting state laws, in the United States implemented indoor tanning legislation since 2003. Conclusion: Since 2003, access to indoor tanning has become increasingly restricted around the world.

Patients with recessive dystrophic epidermolysis bullosa (RDEB) have incurable skin fragility, blistering, and skin wounds due to mutations in the gene that codes for type VII collagen (C7) that mediates dermal-epidermal adherence in human skin. In this study, we evaluated if topically applied human recombinant C7 (rC7) could restore C7 at the dermal-epidermal junction (DEJ) and enhance wound healing. We found that rC7 applied topically onto murine skin wounds stably incorporated into the newly formed DEJ of healed wounds and accelerated wound closure by increasing re-epithelialization. Topical rC7 decreased the expression of fibrogenic transforming growth factor-β2 (TGF-β2) and increased the expression of anti-fibrogenic TGF-β3. These were accompanied by the reduced expression of connective tissue growth factor, fewer α smooth muscle actin (α-SMA)-positive myofibroblasts, and less deposition of collagen in the healed neodermis, consistent with less scar formation. In addition, using a mouse model in which skin from C7 knock out mice was grafted onto immunodeficient mice, we showed that applying rC7 onto RDEB grafts with wounds restored C7 and anchoring fibrils (AFs) at the DEJ of the grafts and corrected the dermal-epidermal separation. The topical application of rC7 may be useful for treating patients with RDEB and patients who have chronic skin wounds.

Patient-centered and professional dermatology organizations use social networking sites; however, academic journals tend to lag behind significantly. Although some journals are active in social media, most have yet to recognize the potential benefits of fully embracing popular social networks.
