Statins, fibrates, and melanoma risk: a systematic review and meta-analysis.

BACKGROUND: Large randomized, controlled clinical trials of lovastatin and gemfibrozil for heart disease prevention have reported statistically significantly lower melanoma incidences in persons receiving these medications. Results of in vitro animal model and human case-control studies also suggest that statins and fibrates may reduce the risk of melanoma. METHODS: We performed a systematic review of trials that randomly assigned participants to receive statins or fibrates versus an alternative therapy for a minimum of 6 months. Trials were identified by searching five electronic databases and the reference lists of eligible publications. Unpublished data were solicited from trial investigators and pharmaceutical companies. A meta-analysis was performed using a fixed-effects model, and odds ratios (ORs) with 95% confidence intervals (CIs) were calculated to estimate pooled treatment effects. All statistical tests were two-sided. RESULTS: We obtained data on incident melanomas from 20 of 36 qualifying randomized controlled trials (12 statin trials and eight fibrate trials), with a total of 70,820 participants. A total of 127 melanomas occurred among the 39,426 participants in the statin trials (59 among the 19,872 statin group participants and 68 among the 19,554 control group participants). A total of 27 melanomas occurred among the 31,394 participants enrolled in the fibrate trials (seven among the 12,324 fibrate group participants and 20 among the 19,070 control group participants). Overall, incidence of melanoma was not statistically significantly associated with the use of either statins (OR = 0.87, 95% CI = 0.61 to 1.23) or fibrates (OR = 0.45, 95% CI = 0.20 to 1.01). In a subgroup analysis by drug, only lovastatin use (in one trial) was statistically significantly associated with lower incidence of melanoma (OR = 0.52, 95% CI = 0.27 to 0.99). CONCLUSIONS: These findings do not validate the possibility that statins or fibrates prevent melanoma.

Indoor tanning attitudes and practices of US dermatologists compared with other medical specialists.

OBJECTIVE: To compare the indoor tanning attitudes and practices of dermatologists with physicians in other medical specialties (internal medicine, pediatrics, and family medicine) commonly providing sun safety counseling to patients. DESIGN: Cross-sectional study. SETTING: Questionnaire mailed to randomly selected US dermatologists, internists, family practitioners, and pediatricians. RESULTS: The overall response rate was 38% (364/949): 71% indicated that patients had asked their opinions about indoor UV tanning, 80% believed that UV tanning was unsafe, and 90% agreed they would counsel patients against nonmedical indoor UV tanning. Many supported increased UV tanning legislation, including minimum age restrictions (91%) and parental consent requirements (90%). Dermatologists were significantly more likely than other physicians to respond to the survey (52% vs 31%, P<.001), speak with patients about indoor UV tanning (odds ratio [OR], 26.5; 95% confidence interval [CI], 9.5-74.1]), believe that indoor UV tanning is unsafe (OR, 14.0; 95% CI, 5.0-39.4), and support increased regulation (OR, 11.7; 95% CI, 1.5-88.5). Women discouraged indoor UV tanning more than men (OR, 5.2; 95% CI, 1.8-15.2). Physicians who had used indoor UV tanning (19%) more often agreed that non-UV tanning lotion (OR, 2.0; 95% CI, 1.1-3.8) and airbrush tanning (OR, 1.9; 95% CI, 1.1-3.4) were safe but did not differ in attitudes regarding UV tanning safety. Physicians practicing in the Northeast and Midwest were more likely to support UV tanning to improve mood (OR, 2.0; 95% CI, 1.1-3.5) and more commonly believed that UV tanning could help treat depression (OR, 2.6; 95% CI, 1.5-4.6) or prevent vitamin D deficiency (OR, 1.7; 95% CI, 1.0-2.8). CONCLUSIONS: Physicians, especially dermatologists, are frequently asked about and generally discourage indoor UV tanning. Dermatologists regard indoor UV tanning more negatively compared with other physicians. Physician sex and geographic location were associated with specific indoor UV tanning attitudes.

Uniform resource locator decay in dermatology journals: author attitudes and preservation practices.

OBJECTIVES: To describe dermatology journal uniform resource locator (URL) use and persistence and to better understand the level of control and awareness of authors regarding the availability of the URLs they cite. DESIGN: Software was written to automatically access URLs in articles published between January 1, 1999, and September 30, 2004, in the 3 dermatology journals with the highest scientific impact. Authors of publications with unavailable URLs were surveyed regarding URL content, availability, and preservation. MAIN OUTCOME MEASURES: Uniform resource locator use and persistence and author opinions and practices. RESULTS: The percentage of articles containing at least 1 URL increased from 2.3% in 1999 to 13.5% in 2004. Of the 1113 URLs, 81.7% were available (decreasing with time since publication from 89.1% of 2004 URLs to 65.4% of 1999 URLs) (P<.001). Uniform resource locator unavailability was highest in The Journal of Investigative Dermatology (22.1%) and lowest in the Archives of Dermatology (14.8%) (P=.03). Some content was partially recoverable via the Internet Archive for 120 of the 204 unavailable URLs. Most authors (55.2%) agreed that the unavailable URL content was important to the publication, but few controlled URL availability personally (5%) or with the help of others (employees, colleagues, and friends) (6.7%). CONCLUSIONS: Uniform resource locators are increasingly used and lost in dermatology journals. Loss will continue until better preservation policies are adopted.

What dermatologists do not know about smallpox vaccination: results from a worldwide electronic survey.

The risk of a bioterrorist attack with smallpox has increased owing to breakthroughs in the de novo synthesis of long-chain DNA molecules. Although the leading roles of dermatologists in diagnosing recent outbreaks of cutaneous anthrax and monkeypox demonstrate the importance of dermatologist preparedness for bioterrorism, dermatologist knowledge regarding smallpox vaccination has not been extensively examined. We conducted a cross-sectional worldwide electronic survey of all members of the American Academy of Dermatology with available e-mail addresses. The response rate was 23% (1,303/5,723): 34% of respondents were women, 52% were age 50 or older, 85% practiced in the US, and 90% reported English as their primary language. Less than 37% indicated the Centers for Disease Control and Prevention estimated rate of death owing to smallpox vaccination (1 in 1,000,000), and many failed to identify vaccination contraindications: previous myocardial infarction (83%), angina (83%), congestive heart failure (78%), steroid eye drop use (65%), and the non-emergency vaccination of those younger than age 18 (95%). Widespread dermatologist smallpox vaccination knowledge deficits pinpoint opportunities for educational efforts.

Compliance with youth access regulations for indoor UV tanning.

OBJECTIVES: To describe youth access to indoor UV tanning and youth discount pricing incentives in 4 states with different age restrictions: Colorado (no age restrictions), Texas (age 13 years), Illinois (age 14 years), and Wisconsin (age 16 years). DESIGN: Cross-sectional telephone survey conducted in October 2003 using a standardized script to assess the practices of randomly selected UV tanning operators. PARTICIPANTS: Randomly selected licensed indoor UV tanning facility operators in Colorado, Texas, Illinois, and Wisconsin. MAIN OUTCOME MEASURES: Number of facilities (1) complying with indoor UV tanning minimum age regulations for a 12-year-old potential patron and a 15-year-old potential patron and (2) offering youth discounts. RESULTS: For a 12-year-old potential patron, 62% of facilities in states with minimum age restrictions prohibiting 12-year-olds had an operator report that they would not permit indoor tanning (Texas, 23%; Illinois, 74%; and Wisconsin, 89%) compared with 18% in Colorado, a state without youth access regulations. For a 15-year-old patron, most facilities in Wisconsin, the only state with a minimum age restriction for 15-year-olds, prohibited access (77%). Overall, 15% of operators offered youth discounts: Texas, 23%; Illinois, 14%; Wisconsin, 11%; and Colorado, 11%. CONCLUSIONS: Tanning facilities in 4 states offered price incentives directed at youths. State youth access regulations were associated with decreased youth access to indoor tanning. High compliance levels in states with long-standing youth access regulations (Illinois and Wisconsin) demonstrate the potential for successful tanning industry youth access regulation.

A case for informed consent? Indoor UV tanning facility operator's provision of health risks information (United States).

OBJECTIVE: Indoor UV tanning is associated with skin cancer. This study describes consumer health risks information provided by indoor UV tanning facility operators in four states (Colorado, Illinois, Texas, and Wisconsin) with varying operator training, regulations, enforcement and penalties. METHODS: Using a cross-sectional survey study design, 100 randomly selected licensed indoor UV tanning facilities from each state were surveyed anonymously by telephone. Facility operators were questioned regarding the provision of information on potential adverse effects of indoor UV exposure. RESULTS: Of 628 licensed indoor UV tanning facilities contacted, 400 facilities were surveyed. Most (87%) advised patrons of the potential risk of sunburn from indoor tanning. Less than half of facility operators in Colorado, Texas and Wisconsin informed patrons about the risk of skin cancer (42, 43 and 48%, respectively) compared with 81% of Illinois operators. Likewise, more operators in Illinois reported the risk of premature aging (79%) compared with other states (41% Colorado, 43% Texas and 51% Wisconsin). CONCLUSIONS: Tanning facility operators frequently misinformed patrons of indoor UV exposure risks. The provision of informed consent by indoor tanning facility operators needs improved adaptation by the tanning industry as a standard for customer service.
