Sunbed use legislation in Europe: assessment of current status.

BACKGROUND: The use of UV-emitting tanning devices for cosmetic purposes is associated with an increased risk of melanoma and non-melanoma skin cancer. Young women are the most frequent users, therefore, there is an increasing concern about the regulation of sunbed use. OBJECTIVE: The primary objective is to assess the current legislation on sunbed use among European countries. METHODS: We developed a 30-item questionnaire to gather the most relevant information about sunbed use legislation. The questionnaire was sent to Euromelanoma coordinators and to designated coordinators out of the Euromelanoma network. RESULTS: We obtained a response rate of 64%. More than 25% of the countries did not report any specific legislation. Roughly one-third of the countries does not have a restriction for minors. Even in countries with a specific legislation, a lack or insufficient enforcement of age limit was observed in up to 100% of the inspections based on the PROSAFE report from 2012. Self-tanning devices were reported in 50%, and almost 40% of countries do not require supervision of use. Although a warning display is required in 77% of cases, a signed informed consent is not required in 80%. In the vast majority of cases, the number of licensed or closed tanning centres is unknown. CONCLUSIONS: Despite the evidence of its harmful effects, and its frequent use by young people, many of whom are at high risk of skin cancer because of fair skin, a significant number of European countries lack a specific legislation on tanning devices. In order to limit the access of young people to sunbeds, a more strictly enforced regulation is needed, as well as regulation regarding advertisement, and location of tanning centres, in addition to health promotion campaigns that target the vulnerable population of young women seeking its use for improved cosmesis.

The regular use of an emollient improves symptoms of atopic dermatitis in children: a randomized controlled study.

BACKGROUND: Emollients are considered as a first-line therapy for the treatment of atopic dermatitis (AD). However, evidence-based proof that the regular use of emollients reduces AD severity is lacking. OBJECTIVE: To assess whether the regular use of emollients results in a reduction in AD severity in children with AD. METHODS: In this multicentre randomized, parallel group, open-label study, children with mild-to-moderate AD were recruited during a flare. After flare resolution with a topical corticosteroid, patients were randomized to V0034CR emollient, reference emollient or no emollient (1:1:1 ratio), for 12 weeks. AD severity was assessed regularly by physicians [Scoring for Atopic Dermatitis (SCORAD) and subcomponents, IGA] and by parents (PO-SCORAD and POEM). RESULTS: A total of 335 patients were randomized to V0034CR (n = 111), reference emollient (n = 116) or no emollient (n = 108). After 12 weeks of treatment, SCORAD score was reduced by 5.28 points in the V0034CR group and by 3.36 points in the reference emollient group compared with the no emollient group (+4 points; P < 0.001 in both emollient groups vs. no emollient group). In a similar manner, PO-SCORAD score was reduced by 4.88 and 2.67 points in the V0034CR and reference emollient groups, respectively, but increased by 2.90 points in the no emollient group (P < 0.001). Similar results were observed for POEM. A continuous decrease in all scores was observed over the 12-week treatment period. At the end of the study, the percentage of patients in complete remission (i.e. without a new flare over the treatment period) was higher in the V0034CR (59.5%) and reference emollient (44.3%) groups than in the no emollient group (29.8%; P < 0.001). CONCLUSION: These results demonstrate that the regular use of emollients in children with mild-to-moderate AD reduces the severity of symptoms and, therefore, support their use as a first-line treatment for these patients.

Efficacy and safety of secukinumab in the treatment of moderate-to-severe plaque psoriasis: a randomized, double-blind, placebo-controlled phase II dose-ranging study.

BACKGROUND: Conventional systemic therapies for plaque psoriasis have not fully met the needs of patients, and although current biologic treatments are generally well tolerated, concerns exist with respect to long-term safety. Interleukin (IL)-17A is believed to be an important effector cytokine in the pathogenesis of psoriasis and is produced by Th17 cells, a class of helper T cells that act outside the established Th1/Th2 paradigm for regulation of innate and adaptive immunity. OBJECTIVES: To assess the efficacy and safety of different doses of secukinumab, a fully human anti-IL-17A IgG1κ monoclonal antibody, in patients with moderate-to-severe plaque psoriasis. METHODS: Patients (n = 125) were randomized 1 : 1 : 1 : 1 : 1 to receive subcutaneous doses of placebo (n = 22) or secukinumab [1 × 25 mg (n = 29), 3 × 25 mg (n = 26), 3 × 75 mg (n = 21) or 3 × 150 mg (n = 27)] at weeks 0, 4 and 8. After the 12-week treatment period, patients entered a follow-up period of 24 weeks. The primary efficacy outcome was at least 75% improvement from baseline in the Psoriasis Area and Severity Index score (PASI 75); secondary outcomes included the Investigator's Global Assessment (IGA) and PASI 90 and 50 response rates. RESULTS: After 12 weeks of treatment, secukinumab 3 × 150 mg and 3 × 75 mg resulted in significantly higher PASI 75 response rates vs. placebo (82% and 57% vs. 9%; P < 0·001 and P = 0·002, respectively). Higher PASI 75 response rates compared with placebo were maintained throughout the follow-up period with these dosages [week 36, 26% (n = 7) and 19% (n = 4) vs. 4% (n = 1), respectively], with a gradual decline of PASI 75 response over time after the dosing period. IGA response rates were significantly higher in the 3 × 150 mg group vs. placebo at week 12 (48% vs. 9%; P = 0·005) and were consistently higher for the 3 × 150 mg and 3 × 75 mg groups vs. placebo at all time points from week 4 onward. The PASI 90 response rate was significantly higher in the 3 × 150 mg group vs. placebo (52% vs. 5%) at week 12 and remained higher during the follow-up period. Secukinumab was well tolerated. Two cases of neutropenia (≤ grade 2) were reported in the 3 × 150 mg cohort. CONCLUSIONS: Treatment with subcutaneous secukinumab 3 × 75 mg and 3 × 150 mg met the primary outcome of PASI 75 response achievement after 12 weeks, demonstrating efficacy in moderate-to-severe psoriasis.

Waardenburg syndrome.

Waardenburg syndrome (WS) is caused by autosomal dominant mutations, and is characterized by pigmentary anomalies and various defects of neural crest derived tissues. We report a very interesting case of type 1 WS (WS 1) in an adult who presented all the symptoms characteristic of this syndrome. One particularly important clinical feature of WS is congenital hearing loss, which may severely handicap a child. A careful clinical description is useful to differentiate between various types of WS and other associated auditory-pigmentary syndromes. Type WS 1, characterized by dystopia canthorum, is caused by loss of function mutations in the PAX3 gene.
