With more surface area available for interactions with other materials around them, nanomaterials can Ôperform exceptional feats of conductivity, reactivity and optical sensitivityÕ. 1 Nanotechnology is maturing rapidly, and is having an effect in medicine, electronics, food science, space, energy, the environment, and consumer products such as sunscreens and cosmetics. 2 Titanium dioxide and zinc oxide become transparent at the nanoscale (< 100 nm). This property, combined with their ability to absorb and reflect ultraviolet (UV) light, has led to nanosized titanium dioxide and zinc oxide particles being used in sunscreens to eliminate the undesired whitening effect of the large-sized particles. There are concerns, however, that these particles might penetrate through the protective layers of the skin, enter viable skin cells, and react with UV light to form reactive species such as hydroxyl radicals that can damage DNA in cells. 3,4 Many business, academic, government and environmental organizations have questioned whether unexpected health consequences could result from the very properties of nanostructured materials that make them so attractive. 2,4,5 In 2004, the United KingdomÕs Royal Society and Royal Academy of Engineering issued a report that expressed concerns about nanotechnology use in sunscreens and cosmetics. 5 In 2006, AustraliaÕs Department of Health and Ageing performed a review of scientific literature on the safety of nanosized titanium dioxide and zinc oxide in sunscreens, and concluded that Ôthe weight of current evidence is that they remain on the surface of the skin and in the outer dead layerÕ. 6 However, the studies conducted to date examined the penetration of nanosized particles in healthy, undamaged skin. The question of what happens to nanosized particles when the skinÕs barrier is compromised, such as when it is sunburned, chronically photodamaged, excoriated or affected by common diseases such as seborrhoeic dermatitis or eczema, is unanswered. 4 Further laboratory

We communicate the good results that we obtained when treating seven patients suffering from AC with ingenol mebutate (IM) 0,015% concentration gel on three consecutive days. Three patients achieved complete clearance and four significant improvement. IM is a topical field treatment approved for actinic keratosis. To our knowledge, reported experience in the management of AC with IM is very limited. Local skin responses grade 3 were the main adverse event observed and they resolved in all patients without specific therapy within 1 to 2 weeks. IM is characterized by its rapid clinical effect, its favorable safety profile and its dosing period of only 3 days, shorter than with other field therapies. All these facts make it an attractive new therapy for AC, with need for further study.

The patient's history included temporal arteritis, for which he had been receiving 20 to 30 mg/d oral prednisone for the previous 13 months. A physical examination revealed 4 or 5 violaceous tumorous lesions on the face (Figure 1) and on the arms. A biopsy of one of the lesions in the nasal dorsum revealed a biphasic vascular spindle-cell growth occupying the entire thickness of the dermis that was characteristic of tumor-phase KS (Figures 2

Its epidemiology is suggestive of an infectious disease and in 1994 Chang and coworkers identified DNA sequences corresponding to a previously unidentified herpes virus—human herpes virus 8 (HHV-8)—in AIDS-associated KS biopsies. It is now believed that the presence of HHV-8 is a necessary condition but not sufficient on its own to cause KS. Other factors such as immunosuppression should also be considered and it is known that immunosuppressive therapy increases the risk of KS.We describe a patient who developed KS after prolonged prednisone therapy for temporal arteritis.

There are many studies that assess this discipline in the general population, but few studies analyse the paediatric population exclusively. The aims of this study are to describe the distribution of diseases consulted through teledermatology, the use of this technique to avoid face-to-face consultations, and the agreement between virtual and face-to-face diagnoses, in the paediatric population. The work consisted of an observational and retrospective study of the virtual consultations made between May 2011 and January 2015 through a store-and-forward teledermatology programme, involving patients from 0 to 15 years. We collected demographic data, as well as the diagnoses made by the paediatrician who made the virtual consultation, and by the dermatologists who assessed the virtual and the face-to-face consultations, the indication given by the dermatologist who assessed the virtual consultation (discharge or referral), reason for referral, and diagnostic agreement rate. A total of 183 virtual consultations were analysed. The most frequent diagnoses were inflammatory diseases (39%), benign pigmented lesions (23%), and infectious diseases (20%). Almost half of the virtual consultations (48%) were referred for a face-to-face diagnosis. Diagnostic agreement between the dermatologist who evaluated the virtual consultation and the dermatologist who evaluated the face-to-face consultation was 89%, and 66% between the paediatrician who made the virtual consultation and the dermatologist who assessed it. Virtual consultations have a similar disease distribution to conventional (face-to-face) referrals. Approximately half of the virtual consultations do not require a subsequent face-to-face visit. The agreement rate between the diagnoses given by both dermatologists (virtual and face-to-face diagnoses) is high.

There is no evidence-based therapy available. The use of sodium thiosulfate (STS) has been increasingly described. Herein we describe two patients who responded well to this treatment.
