[PMID: 35740705 PMCID: PMC9221787 DOI: 10.3390/children9060768] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/28/2022] [Revised: 05/17/2022] [Accepted: 05/20/2022] [Indexed: 11/16/2022]
Abstract
Tanning beds have been classified as carcinogenic to humans. As a result, many countries have enacted laws regulating the use of commercial tanning beds, including bans for minors. However, there is no international overview of the current legal status of access restrictions for minors that provides details on their specific design regarding age limits and possible exceptions to the statutory regulation. Therefore, we performed a comprehensive web search of current tanning bed legislation for minors on the three continents North America, Australia, and Europe. Our findings regarding the existence and concrete design of access restrictions are presented graphically, using maps. We found a wide variety of different legislations. In Australia, a total ban on tanning beds exists, while in New Zealand, tanning bed use is banned for minors. In Europe, about half of the countries have implemented a strict ban for minors. In North America, we found differences in the age limit for access restrictions between the states, provinces, and territories for those regions that implemented a ban for minors. In the United States, some states have rather “soft bans” that allow use by minors with different types of parental consent. The patchwork in legislation calls for harmonization. Therefore, our comparison is an important starting point for institutions such as the World Health Organization or the European Commission to advance their goals toward a harmonization of tanning bed legislation in general and for minors in particular.

Abstract
To shed further light on the ongoing debate whether sunbed use may increase melanoma risk, we have critically assessed the scientific literature that is at present available, focussing on a meta-analysis that we published recently. Our literature search identified several meta-analyses that report a weak association for ever-exposure to UV radiation from a solarium with melanoma risk. However, the quality of studies included in these meta-analyses and the resulting evidence levels and grades of recommendation were very low due to the lack of interventional trials and because of severe limitations of many of the observational studies. The results of cohort and case-control studies published until today do not prove causality, not even by the Hill criteria. The overall quality of these observational studies and the resulting evidence levels are low due to severe limitations (including unobserved or unrecorded confounding), which leads to bias. It must be recognized that in the majority of studies, published to date, many of the confounding factors, including sun exposure, sunburns and skin type, have not been adequately and systematically recorded and adjusted for. We conclude that the many limitations of the individual studies and the resulting low levels of evidence and grades of recommendation do at present not allow postulation of a causal relationship between solarium use and melanoma risk. At present, there is no convincing evidence that moderate/responsible solarium use increases melanoma risk.

Abstract
Involving and engaging stakeholders is crucial for studying and managing the complex interactions between marine ecosystems and human health and wellbeing. The Oceans and Human Health Chair was founded in the town of Roses (Catalonia, Spain, NW Mediterranean) in 2018, the fruit of a regional partnership between various stakeholders, and for the purpose of leading the way to better health and wellbeing through ocean research and conservation. The Chair is located in an area of the Mediterranean with a notable fishing, tourist, and seafaring tradition and is close to a marine reserve, providing the opportunity to observe diverse environmental conditions and coastal and maritime activities. The Chair is a case study demonstrating that local, collaborative, transdisciplinary, trans-sector, and bottom-up approaches offer tremendous opportunities for engaging coastal communities to help support long-lasting solutions that benefit everyone, and especially those living by the sea or making their living from the goods and services provided by the sea. Furthermore, the Chair has successfully integrated most of its experts in oceans and human health from the most prestigious institutions in Catalonia. The Chair focuses on three main topics identified by local stakeholders: Fish and Health; Leisure, Health, and Wellbeing; and Medicines from the Sea. Led by stakeholder engagement, the Chair can serve as a novel approach within the oceans and human health field of study to tackle a variety of environmental and public health challenges related to both communicable and non-communicable diseases, within the context of sociocultural issues. Drawing on the example provided by the Chair, four principles are established to encourage improved participatory processes in the oceans and human health field: bottom-up, “think local”, transdisciplinary and trans-sectorial, and “balance the many voices”.

Abstract
Indoor tanning leads to melanoma, the fifth most common cancer in the USA. The highest rate of indoor tanning is among young women whose exposure to tanned images in the media is linked to protanning attitudes. This study evaluated the efficacy of a media literacy intervention for reducing young women's indoor tanning. Intervention participants analyzed the content and functions of the media influencing protanning attitudes and produced counter-messages to help themselves and peers resist harmful media effects. The message production was of two types: digital argument production or digital story production. The control group received assessments only. This three-group randomized design involved 26 sorority chapters and 247 members in five Midwestern states where indoor tanning is prevalent. At 2- and 6-month follow-up assessments, those in the two intervention conditions were less likely to be indoor tanners (p = .033) and reported lower indoor tanning intentions (p = .002) compared to those in the control condition. No difference between the two intervention groups was found for behavior. Although the argument group exhibited slightly weaker indoor tanning intentions than the story group, the difference was not significant. The results provide the first evidence of the efficacy of a media literacy intervention for indoor tanning reduction. Implications for participative engagement interventions are discussed.

Abstract
IMPORTANCE In the United States and Minnesota, melanoma incidence is rising more steeply among women than men younger than 50 years. To our knowledge, no study has examined age- and sex-specific associations between indoor tanning and melanoma to determine if these trends could be due to greater indoor tanning use among younger women. OBJECTIVE To examine associations between indoor tanning and melanoma among men and women younger than 50 years. DESIGN, SETTING, AND PARTICIPANTS Population-based case-control study conducted in Minnesota of 681 patients (465 [68.3%] women) diagnosed as having melanoma between 2004 and 2007, and 654 controls (446 [68.2%] women), ages 25 to 49 years. EXPOSURE Indoor tanning, defined as any use, first age of use, and total sessions. MAIN OUTCOMES AND MEASURES Crude and adjusted odds ratios (ORs) and 95% CIs were calculated for melanoma in relation to indoor tanning exposure for men and women by diagnosis or reference age (<30, 30-39, 40-49 years). Sex-specific associations for indoor tanning and melanoma by anatomic site were examined. RESULTS Compared with women aged 40 to 49 years, women younger than 40 years initiated indoor tanning at a younger age (16 vs 25 years, P < .001) and reported more frequent indoor tanning (median number of sessions, 100 vs 40, P < .001). Women younger than 30 years were 6 times more likely to be in the case than the control group if they tanned indoors (crude OR, 6.0; 95% CI, 1.3-28.5). Odds ratios were also significantly elevated among women, ages 30 to 49 years (adjusted OR, 3.5; 95% CI, 1.2-9.7 for women 30-39 years; adjusted OR, 2.3; 95% CI, 1.4-3.6 for women 40-49 years); a dose response was observed among women regardless of age. Among men, results by age were inconsistent. The strongest OR for indoor tanning by anatomic site was for melanomas arising on the trunk of women (adjusted OR, 3.7; 95% CI, 1.9-7.2). CONCLUSIONS AND RELEVANCE Indoor tanning is a likely factor for the steeper increase in melanoma rates in the United States among younger women compared with men, given the timing of when women initiated indoor tanning relative to diagnosis. The melanoma epidemic can be expected to continue unless indoor tanning is restricted and reduced.

Abstract
BACKGROUND We report the development of a cutaneous melanoma risk algorithm based upon seven factors; hair color, skin type, family history, freckling, nevus count, number of large nevi, and history of sunburn, intended to form the basis of a self-assessment Web tool for the general public. METHODS Predicted odds of melanoma were estimated by analyzing a pooled dataset from 16 case-control studies using logistic random coefficients models. Risk categories were defined based on the distribution of the predicted odds in the controls from these studies. Imputation was used to estimate missing data in the pooled datasets. The 30th, 60th, and 90th centiles were used to distribute individuals into four risk groups for their age, sex, and geographic location. Cross-validation was used to test the robustness of the thresholds for each group by leaving out each study one by one. Performance of the model was assessed in an independent UK case-control study dataset. RESULTS Cross-validation confirmed the robustness of the threshold estimates. Cases and controls were well discriminated in the independent dataset [area under the curve, 0.75; 95% confidence interval (CI), 0.73-0.78]. Twenty-nine percent of cases were in the highest risk group compared with 7% of controls, and 43% of controls were in the lowest risk group compared with 13% of cases. CONCLUSION We have identified a composite score representing an estimate of relative risk and successfully validated this score in an independent dataset. IMPACT This score may be a useful tool to inform members of the public about their melanoma risk.

Abstract
The last 30 years has seen a revolution in melanoma. Fundamental elements of the surgical, adjuvant medical, and systemic therapy for the disease have been significantly altered toward improved management and better outcomes. The intent of this article is to reflect on past efforts and research in melanoma and the current landscape of treatment of melanoma. The authors also hope to capture the excitement currently rippling through the field and the hope for a cure. The intent of treatment of advanced melanoma, which was once considered incurable, has changed from palliative to potentially curative.

Abstract
BACKGROUND Indoor tanning increases skin cancer risk. Beyond early research describing melanoma and sun lamps, few recent reports describe where individuals indoor tan and whether skin cancer risk varies by location (business, home-based). OBJECTIVE We sought to assess where individuals tanned indoors and skin cancer risk by tanning device location. METHODS Multivariate logistic regression was conducted in 2 US case-control studies of melanoma (1161 cases, 1083 controls, ages 25-59 years) and early-onset basal cell carcinoma (375 cases, 382 controls, age<40 years) conducted between 2004 and 2010. RESULTS Most indoor tanners (86.4%-95.1%), especially younger individuals, tanned exclusively in businesses. Persons who used indoor tanning exclusively in businesses were at increased risk of melanoma (odds ratio 1.82, 95% confidence interval 1.47-2.26) and basal cell carcinoma (odds ratio 1.69, 95% confidence interval 1.15-2.48) compared with non-users. Melanoma risk was also increased in the small number who reported tanning indoors only at home relative to non-users (odds ratio 4.14, 95% confidence interval 1.75-9.78); 67.6% used sun lamps. LIMITATIONS Self-reported tanning and potential recall bias are limitations. CONCLUSION Business-only tanning, despite claims of "safe" tanning, was positively associated with a significant risk of melanoma and basal cell carcinoma. Home tanning was uncommon and mostly from sun lamps, which were rarely used by younger participants. Regardless of location, indoor tanning was associated with increased risk of skin cancer.

Abstract
BACKGROUND The incidence of melanoma and nonmelanoma skin cancer continues to increase. To detect lesions at an earlier phase in their progression, skin cancer screening programs have been advocated by some. However, the effectiveness of skin cancer screening and the ideal population that these screenings should target have yet to be firmly established. This study details the relationship of a group of well-known risk factors with presumptive diagnoses in a large series of individuals self-referred for free skin cancer screening. METHODS Data obtained during 2007 to 2010 from a descriptive cross-sectional study skin cancer screening program are presented. Participant history was recorded using standardized medical history forms prior to skin examination. Screeners conducted a skin examination varying from whole-body to limited areas (per participant preference) and recorded diagnoses. Diagnoses were assigned to the nonmelanoma cancer (NMC) or suspicious pigmented lesion group for analysis. RESULTS A presumptive diagnosis of NMC was associated with male sex, age ≥ 50 years, personal history of skin cancer, lower skin phototype, increased sunscreen use, and increased chronic sun exposure (all P values ≤ .0001). After controlling for skin phototype, increased sunscreen use was not associated with a presumptive diagnosis of NMC (P = .96). Presumptive diagnosis of a suspicious pigmented lesion was associated with a reported history of "changing mole" (P < .0001) and negatively associated with age ≥ 50 years (P < .0001) and a personal history of skin cancer (P = .0119). CONCLUSIONS Several known risk factors for nonmelanoma skin cancer correlated with a presumptive diagnosis of NMC. The yield of presumptive atypical pigmented lesions was increased in participants aged < 50 years, supporting the notion that this population may benefit from screening.

Abstract
This study examined health belief model (HBM) relevant constructs in the context of indoor tanning cessation. Telephone interviews were conducted between December 2011 and April 2012 with participants drawn from the Growing Up Today Study (GUTS) population, specifically, former tanning bed users (N = 14, all females; mean age, 25.65 years) who reported frequent use in 2007, but had quit by 2010. Participants identified important motivations for quitting including health and financial reasons and the central role of family and friends in providing encouragement for indoor tanning cessation. However, participants also noted substantial barriers to maintaining indoor tanning quitting (e.g., social pressures to look good, tanning salon incentives). Participants' experience of withdrawal highlighted psychological factors more often than physical factors; some were open to resuming use in the future. The findings will be useful in intervention development to encourage cessation, the strengthening of policies to regulate the indoor tanning industry, as well as public health messaging to raise awareness of this prevalent, easily accessible cancer risk behavior.

Abstract
In October 2011, California became the first US state to ban indoor tanning for minors under age 18 years. Vermont followed in May 2012. Increasingly, scientific evidence shows that artificial tanning raises the risk of skin cancer, including melanoma, a common cancer in adolescents and young adults and the type most likely to result in death. The World Health Organization, the American Academy of Pediatrics, the American Academy of Dermatology, the American Medical Association, and other organizations strongly recommend legislation to ban minors under age 18 from indoor tanning. Several nations have banned teen tanning. Yet, tanning in salons is still a prevalent practice in the United States, especially among teen girls, where rates for the oldest teens approach 40%. There is no federal legislation to restrict minors from salon tanning. More than 60% of states have some kind of legislation regarding minors' use of tanning salons, but only California and Vermont have passed complete bans of indoor tanning for minors. The Indoor Tanning Association, an industry advocacy group, has vigorously opposed legislative efforts. Pediatricians can play key roles in counseling families and with legislative efforts. In this update, we review the prevalence of salon tanning, association with skin cancer risk, tanning addiction, the roles of the federal and state governments in regulation and legislation, and responses to arguments created by industry to oppose legislation. Preventing exposure to artificial tanning may save lives, including young lives, and is a key cancer prevention opportunity for pediatricians.

Abstract
OBJECTIVE To estimate the burden of melanoma resulting from sunbed use in western Europe. DESIGN Systematic review and meta-analysis. DATA SOURCES PubMed, ISI Web of Science (Science Citation Index Expanded), Embase, Pascal, Cochrane Library, LILACS, and MedCarib, along with published surveys reporting prevalence of sunbed use at national level in Europe. STUDY SELECTION Observational studies reporting a measure of risk for skin cancer (cutaneous melanoma, squamous cell carcinoma, basal cell carcinoma) associated with ever use of sunbeds. RESULTS Based on 27 studies ever use of sunbeds was associated with a summary relative risk of 1.20 (95% confidence interval 1.08 to 1.34). Publication bias was not evident. Restricting the analysis to cohorts and population based studies, the summary relative risk was 1.25 (1.09 to 1.43). Calculations for dose-response showed a 1.8% (95% confidence interval 0% to 3.8%) increase in risk of melanoma for each additional session of sunbed use per year. Based on 13 informative studies, first use of sunbeds before age 35 years was associated with a summary relative risk of 1.87 (1.41 to 2.48), with no indication of heterogeneity between studies. By using prevalence data from surveys and data from GLOBOCAN 2008, in 2008 in the 15 original member countries of the European Community plus three countries that were members of the European Free Trade Association, an estimated 3438 cases of melanoma could be attributable to sunbed use, most (n=2341) occurring among women. CONCLUSIONS Sunbed use is associated with a significant increase in risk of melanoma. This risk increases with number of sunbed sessions and with initial usage at a young age (<35 years). The cancerous damage associated with sunbed use is substantial and could be avoided by strict regulations.

Abstract
Sunbed/sunlamp use was recently classified as carcinogenic. This report considers characteristics of those who use sunbeds/sunlamps and the effect of sunbed/sunlamp use on their risk for melanoma within a large case-control study carried out in 1991-1992. Females were more likely than males to have used sunbeds/sunlamps. Use by females increased strongly and significantly with younger ages and with the perceived ability to tan. For females, the individual risk for melanoma increased with typical session time and frequency of sessions. Use before age 20, current use and years of use were not significant. The use patterns of occasional and frequent users were very different. We estimate that typical 5-min sessions would increase the risk for melanoma by 19% for frequent users (10+ sessions) and by 3% for occasional users (1-9 sessions). Body sites that are not generally exposed to sunlight were more common sites of primary melanomas for frequent sunbed/sunlamp users. For males, measures of sunbed/sunlamp use were not significantly associated with melanoma risk.

Abstract
Sunbed use is associated with increased risk of melanoma. Younger people might be more susceptible to the carcinogenic effects of ultraviolet radiation. We investigated the association between sunbed use and risk of early-onset cutaneous malignant melanoma. From the Australian Melanoma Family Study, a multicentre, population-based, case-control-family study, we analysed data for 604 cases diagnosed between ages 18 and 39 years and 479 controls. Data were collected by interview. Associations were estimated as odds ratios (ORs) using unconditional logistic regression, adjusting for age, sex, city, education, family history, skin color, usual skin response to sunlight and sun exposure. Compared with having never used a sunbed, the OR for melanoma associated with ever-use was 1.41 (95% confidence interval (CI) 1.01-1.96), and 2.01 (95% CI 1.22-3.31) for more than 10 lifetime sessions (P(trend) 0.01 with cumulative use). The association was stronger for earlier age at first use (P(trend) 0.02). The association was also stronger for melanoma diagnosed when aged 18-29 years (OR for more than 10 lifetime sessions = 6.57, 95% CI 1.41-30.49) than for melanoma diagnosed when 30-39 years (OR 1.60, 95% CI 0.92-2.77; P(interaction) 0.01). Among those who had ever used a sunbed and were diagnosed between 18 and 29 years of age, three quarters (76%) of melanomas were attributable to sunbed use. Sunbed use is associated with increased risk of early-onset melanoma, with risk increasing with greater use, an earlier age at first use and for earlier onset disease.

Abstract
INTRODUCTION In 2009, the WHO listed ultraviolet (UV) radiation as a group 1 carcinogen. In spite of this, each year, millions of people tan indoor in Western countries. The aim of this review is to summarize evidence of tanning bed carcinogenesis and to present guidelines for use of tanning beds and patient safety advice. METHODS A narrative review of the literature was conducted based on both PubMed and Medline searches and on literature review of the retrieved papers. RESULTS Use of indoor tanning beds represents a significant and avoidable risk factor for the development of both melanoma and nonmelanoma skin cancers. Frequent tanners are more often adolescent females. Tanning beds have additional potential adverse effects such as burns, solar skin damage, infection, and possibly also addictive behavior. DISCUSSION The effort in preventing UV light-induced carcinogenesis should currently be aimed at developing new strategies for public health information. Tanning beds are one preventable source of UV radiation. In the majority of people solar UV radiation continues to be the major factor and therefore anti-tanning campaigns must always include sunbathers.

Abstract
We investigated whether MC1R genotype modifies the effect of sun exposure on melanoma risk in 1,018 cases with multiple melanomas (MPM) and 1,875 controls with one melanoma (SPM). There was some suggestion that MC1R genotype modified the effect of beach and water activities on MPM risk: ORs were 1.94 (95% CI 1.40-2.70) for any activities for no R variants and 1.39 (95% CI 1.05-1.84) with R variants (R151C, R160W, D294H, and D84E) (p for interaction 0.08). MC1R modification of sun exposure effects appeared most evident for MPM of the head and neck: for early life ambient UV, the OR was 4.23 (95% CI 1.76-10.20) with no R and 1.04 (95% CI 0.40-2.68) with R (p for interaction = 0.01; p for three-way interaction = 0.01). Phenotype modified the effect of sun exposure and MPM in a similar manner. We conclude that MC1R and pigmentary phenotype may modify the effects of sun exposure on melanoma risk on more continuously sun-exposed skin. Possible explanations include that risk may saturate with higher sun sensitivity for melanomas on continuously sun-exposed sites but continue to increase as sun exposure increases with lower sun sensitivity, or that sun-sensitive people adapt their behavior by increasing sun protection when exposed.

Abstract
BACKGROUND Indoor tanning has been only weakly associated with melanoma risk; most reports were unable to adjust for sun exposure, confirm a dose-response, or examine specific tanning devices. A population-based case-control study was conducted to address these limitations. METHODS Cases of invasive cutaneous melanoma, diagnosed in Minnesota between 2004 and 2007 at ages 25 to 59, were ascertained from a statewide cancer registry; age-matched and gender-matched controls were randomly selected from state driver's license lists. Self-administered questionnaires and telephone interviews included information on ever use of indoor tanning, types of device used, initiation age, period of use, dose, duration, and indoor tanning-related burns. Odds ratios (OR) and 95% confidence intervals (CI) were adjusted for known melanoma risk factors. RESULTS Among 1,167 cases and 1,101 controls, 62.9% of cases and 51.1% of controls had tanned indoors (adjusted OR 1.74; 95% CI, 1.42-2.14). Melanoma risk was pronounced among users of UVB-enhanced (adjusted OR, 2.86; 95% CI, 2.03-4.03) and primarily UVA-emitting devices (adjusted OR, 4.44; 95% CI, 2.45-8.02). Risk increased with use: years (P < 0.006), hours (P < 0.0001), or sessions (P = 0.0002). ORs were elevated within each initiation age category; among indoor tanners, years used was more relevant for melanoma development. CONCLUSIONS In a highly exposed population, frequent indoor tanning increased melanoma risk, regardless of age when indoor tanning began. Elevated risks were observed across devices. IMPACT This study overcomes some of the limitations of earlier reports and provides strong support for the recent declaration by the IARC that tanning devices are carcinogenic in humans.

Abstract
We are seeing a record number of newly diagnosed skin cancers worldwide, with the incidence of melanoma increasing at a faster rate than almost all other cancers. As clinicians, we will have, by far, the greatest impact on reducing this incidence through better methods of early detection of melanoma and proven prevention methods and techniques. The medical community must enhance its efforts to increase its training of new health care personnel who are capable of diagnosing and treating this record number of patients with skin cancer. We must also try to increase the access to our limited number of dermatologists and provide novel ways of patient education such as through skin self-examinations, total body photography, and improved education for our children. By providing easier access to skin examinations, we will increase our chances of detecting melanoma in its earliest and most curable form. The dangers of indoor tanning beds and salons must be transparent to those that use them, focusing on expanding the oversight of such facilities by our local and federal governmental agencies while establishing legislation in several states to further limit their use to our youth, who are especially at high risk for developing melanoma in the future. This review will focus on the epidemiology, prevention, and detection of melanoma.

Abstract
This paper explored how sensation seeking contributes to the likelihood of tanning bed use intentions both directly and indirectly through the way it shapes interaction with peers who use tanning beds and attitudes toward tanning bed. Eight hundred and ninety six (n = 896) male and female college students were recruited for the study. Measured variables included sensation seeking, association with friends who use tanning beds, attitudes toward tanning and tanning bed use intentions. Structural equation modeling was performed to test the hypotheses. In general, results supported the proposed hypotheses and documented that sensation seeking is indirectly associated with tanning bed use intentions through the mediation of association with peers who use tanning beds and attitudes toward tanning. The article discusses theoretical and methodological implications of the findings demonstrating the pathways of influence of sensation seeking on tanning bed use intentions.

Abstract
Adolescents seem to be obsessed with tanning. One third of both adolescents and adults report sunbathing. On average, about 20% of adolescents report ever-using of artificial UV tanning devices with 15% currently using them. Tanning attitudes appear similar for adolescents and adults. The top three reasons for tanning included beliefs that a tan makes them more comfortable socializing with friends, looks better and is attractive. The top reason for using artificial UV tanning devices is also aesthetics, followed by relaxation. Other reasons for using artificial UV tanning devices include vacation preparation and to gain a protective base. Attitudes related to appearance that result in more frequent tanning may be difficult to change.

Abstract
The International Agency for Research on Cancer (IARC) reported meta-analyses of the association of cutaneous malignant melanoma (CMM), finding significant correlations with ever use of sunbeds and first use of sunbeds prior to age 35 years; it did not claim that the associations showed causal links. However, some observational studies in the meta-analysis included individuals in the UK with skin phenotype at increased genetic risk of CMM without adjustment for skin phenotype. Treating the five UK studies separately from the other 14 corrected this oversight. In the original study, the summary relative risk (RR ) of CMM with respect to sunbed use was 1.15 (95% confidence interval [CI], 1.00-1.31). In this study, the similar RR was 1.20 (95% CI, 1.03-1.38). The RR for the five UK studies was 2.09 (95% CI, 1.14-3.84), whereas the RR for the other 14 studies was 1.09 (95% CI, 0.96-1.24). For first use of sunbeds prior to age 35 years, the IARC found a summary RR of 1.75 (95% CI, 1.35-2.36). This study plotted the RRs versus latitude of each study population, with a linear regression analysis carried out for all but the one UK study. The RR increased at 0.077 per degree of latitude and the regression explained 67% of the variance. It is also argued that factors other than sunbed use explain the increasing worldwide trends in CMM. Because solar-UV-simulating sunbeds induce production of vitamin D, the health benefits of their use greatly outweigh any possible risks.

Abstract
BACKGROUND The suntanning industry has grown up over the last decade in Europe, mainly because tanned skin is considered socially desirable and attractive. Because of the potential negative impact of artificial tanning on public health, this study was to investigate tanning bed use behaviour, UV related risk perception and beliefs about tanning in the German population. METHODS In 2007, a representative telephone survey was carried out among 1501 German residents aged 14 years and older. RESULTS More than one fourth (28%) of the German population have used tanning beds at least once before in their lifetime. High-frequency tanning behaviour, i.e. using tanning beds more than 10 times per year, were recorded for 11%. Men and women aged 18 to 44 years and young women under the age of 18 used tanning beds more frequently (>10 times per year). Tanning bed use was positively related to appearance and lifestyle related beliefs as well as to the perception that tanned skin is healthy. CONCLUSION This analysis indicates that tanning bed use is common in Germany. The positive relationships of appearance and health related beliefs with tanning bed use are of great concern. The results indicate underlying misconceptions about the positive effect of artificial UV radiation compared to natural UV radiation particular for high-frequency tanners. The data shows the importance as well as the limitations for risk communication in its current effort to inform effectively about the dangers of artificial UV radiation.

Abstract
OBJECTIVE The purpose of this report is to put the dueling factors of risk and prevention for melanoma in perspective for the thoughtful pediatric specialist to facilitate preteen preventive health counseling. STUDY DESIGN We examined the rate of malignant melanoma among Kentucky residents and compared this rate with indicators of tanning bed prevalence in a large metropolitan area and sunscreen sales from a major distributor. We obtained malignant melanoma annual incidence data from the Kentucky Cancer Registry, which recorded Kentucky population incidence rates over the years 1995 to 2004. The rates reflected 2 malignant melanoma classifications: pre-invasive cancer only, or both invasive and noninvasive cancers combined. RESULTS The age-adjusted incidence rate per hundred thousand for combined invasive and pre-invasive malignant melanoma swelled from 21.9 in 1995 to 31.3 in 2004. The respective invasive-only malignant melanoma incidence rates increased less dramatically, from 17.3 to 20.7, during this same 10-year time period. Since 1983, the number of separate tanning bed businesses increased from 1 in 1983 to 119 by the mid-1990s, and then declined to about 74 separate businesses by 2003. Sunscreen sales data is uneven between states and is currently inconclusive. CONCLUSIONS Although current data cannot draw a precise link between melanoma and the use of tanning beds, the associated risk is implicit, as the ultraviolet A (UVA) and ultraviolet B (UVB) radiation in tanning bed usage is a well-established melanoma risk factor. In advising patients, the pediatric specialist should consider that melanoma rates are poised as a balance of some known risk factors and a few potential preventive factors.

Abstract
Background Melanoma risk is related to sun exposure; we have investigated risk variation by tumour site and latitude. Methods We performed a pooled analysis of 15 case–control studies (5700 melanoma cases and 7216 controls), correlating patterns of sun exposure, sunburn and solar keratoses (three studies) with melanoma risk. Pooled odds ratios (pORs) and 95% Bayesian confidence intervals (CIs) were estimated using Bayesian unconditional polytomous logistic random-coefficients models. Results Recreational sun exposure was a risk factor for melanoma on the trunk (pOR = 1.7; 95% CI: 1.4–2.2) and limbs (pOR = 1.4; 95% CI: 1.1–1.7), but not head and neck (pOR = 1.1; 95% CI: 0.8–1.4), across latitudes. Occupational sun exposure was associated with risk of melanoma on the head and neck at low latitudes (pOR = 1.7; 95% CI: 1.0–3.0). Total sun exposure was associated with increased risk of melanoma on the limbs at low latitudes (pOR = 1.5; 95% CI: 1.0–2.2), but not at other body sites or other latitudes. The pORs for sunburn in childhood were 1.5 (95% CI: 1.3–1.7), 1.5 (95% CI: 1.3–1.7) and 1.4 (95% CI: 1.1–1.7) for melanoma on the trunk, limbs, and head and neck, respectively, showing little variation across latitudes. The presence of head and neck solar keratoses was associated with increased risk of melanoma on the head and neck (pOR = 4.0; 95% CI: 1.7–9.1) and limbs (pOR = 4.0; 95% CI: 1.9–8.4). Conclusion Melanoma risk at different body sites is associated with different amounts and patterns of sun exposure. Recreational sun exposure and sunburn are strong predictors of melanoma at all latitudes, whereas measures of occupational and total sun exposure appear to predict melanoma predominately at low latitudes.

Abstract
The ultraviolet B (UVB) waveband within sunlight is an important carcinogen; however, UVA is also likely to be involved. By ascribing mutations to being either UVB or UVA induced, we have previously shown that human skin cancers contain similar numbers of UVB- and UVA-induced mutations, and, importantly, the UVA mutations were at the base of the epidermis of the tumors. To determine whether these mutations occurred in response to UV, we exposed engineered human skin (EHS) to UVA, UVB, or a mixture that resembled sunlight, and then detected mutations by both denaturing high-performance liquid chromatography and DNA sequencing. EHS resembles human skin, modeling differential waveband penetration to the basal, dividing keratinocytes. We administered only four low doses of UV exposure. Both UVA and UVB induced p53 mutations in irradiated EHS, suggesting that sunlight doses that are achievable during normal daily activities are mutagenic. UVA- but not UVB-induced mutations predominated in the basal epidermis that contains dividing keratinocytes and are thought to give rise to skin tumors. These studies indicate that both UVA and UVB at physiological doses are mutagenic to keratinocytes in EHS.

Abstract
BACKGROUND The incidence of skin cancer, including melanoma, continues to increase. Teenagers are especially vulnerable, as are young females. The incidence of melanoma among young women in their twenties and thirties has begun to increase again. These young people are also the population that frequent tanning salons. OBJECTIVE This voluntary, anonymous, New York University, Institutional Review Board-approved survey was given to students in grades 9 through 12 to ascertain their understanding of what causes skin cancers and the dangers of excessive sun exposure and tanning salons. METHODS AND MATERIALS An Institutional Review Board-approved, 22-question survey was administered anonymously to more than 450 students with 368 returned responses. The survey was administered to students in grades 9 through 12 at two high schools in New York and New Jersey. RESULTS More than 80 percent of students view movie stars as tan and almost 60 percent see "tan" people as better looking. In addition, more than 90 percent believe that a tan does not prevent further damage to the skin (as opposed to the customary belief that a "base" tan can protect against extreme sun exposures, such as when on a tropical vacation). There appears to be a disconnect between knowledge and sun tanning behaviors. Most teenagers still believe that tans are attractive and teenage girls continue to use tanning salons and tan naturally. We need to address the connection between sun tanning in youth and skin cancers years later. Legislation to limit access of tanning salons to teenagers needs to be enacted.

Abstract
An abnormal nevus phenotype is associated with an increased risk of melanoma. We report a pooled analysis conducted using individual nevus data from 15 case-control studies (5,421 melanoma cases and 6,966 controls). The aims were to quantify the risk better and to determine whether relative risk is varied by latitude. Bayesian unconditional logistic random coefficients models were employed to study the risk associated with nevus characteristics. Participants with whole body nevus counts in the highest of 4 population-based categories had a greatly increased risk of melanoma compared with those in the lowest category (pooled odds ratio (pOR) 6.9 (95% confidence interval (CI): 4.4, 11.2) for those aged<50 years and pOR 5.1 (95% CI: 3.6, 7.5) for those aged>or=50). The pOR for presence compared with absence of any clinically atypical nevi was 4.0 (95% CI: 2.8, 5.8). The pORs for 1-2 and >or=3 large nevi on the body compared with none were 2.9 (95% CI: 1.9, 4.3) and 7.1 (95% CI: 4.7, 11.6), respectively. The relative heterogeneities among studies were small for most measures of nevus phenotype, except for the analysis of nevus counts on the arms, which may have been due to methodological differences among studies. The pooled analysis also suggested that an abnormal nevus phenotype is associated most with melanomas on intermittently sun-exposed sites. The presence of increased numbers of nevi, large nevi and clinically atypical nevi on the body are robust risk factors for melanoma showing little variation in relative risk among studies performed at different latitudes.

Abstract
BACKGROUND Skin cancer represents a significant health threat with over 1.3 million diagnoses, 8000 melanoma deaths, and more than $1 billion spent annually for skin cancer healthcare in the US. Despite findings from laboratory, case-control, and prospective studies that indicate a link between youthful indoor tanning (IT) and skin cancer, IT is increasing among US youth. Appearance-focused interventions represent a promising method to counteract these trends. METHODS A total of 430 female indoor tanners were randomized into intervention or no intervention control conditions. Intervention participants received an appearance-focused booklet based on decision-theoretical models of health behavior. Outcome variables included self-reports of IT behavior and intentions, as well as measures of cognitive mediating variables. RESULTS Normative increases in springtime IT rates were significantly lower (ie, over 35%) at 6-month follow-up in intervention versus control participants with similar reductions in future intentions. Mediation analyses revealed 6 cognitive variables (IT attitudes, fashion attitudes, perceived susceptibility to skin cancer and skin damage, subjective norms, and image norms) that significantly mediated change in IT behavior. CONCLUSIONS The appearance-focused intervention demonstrated strong effects on IT behavior and intentions in young indoor tanners. Appearance-focused approaches to skin cancer prevention need to present alternative behaviors as well as alter IT attitudes. Mediational results provide guides for strengthening future appearance-focused interventions directed at behaviors that increase risk of skin cancer.

Abstract
Background Sun sensitivity of the skin is a risk factor for the development of cutaneous melanoma and other skin cancers. Epidemiological studies on causal factors for the development of melanoma must control for sun sensitivity as a confounder. A standardized instrument for measuring sun sensitivity has not been established yet. It is assumed that many studies show a high potential of residual confounding for sun sensitivity. In the present study, a new questionnaire for the assessment of self-reported sun sensitivity is administered and examined. Methods Prior to an occupational skin cancer screening program, the 745 participating employees were asked to fill in a questionnaire for self-assessment of sun sensitivity. The questionnaire was developed by experts of the working group "Round Table Sunbeds" (RTS) to limit the health hazards of sunbed use in Germany. A sun sensitivity score (RTS-score) was calculated using 10 indicators. The internal consistency of the questionnaire and the agreement with other methods (convergent validity) were examined. Results The RTS-score was calculated for 655 study participants who were 18 to 65 years of age. The correlation of the items among each other was between 0.12 and 0.62. The items and the RTS-score correlated between 0.46 and 0.77. The internal consistency showed a reliability coefficient with 0.82 (Cronbach's alpha). The comparison with the Fitzpatrick classification, the prevailing standard, was possible in 617 cases with a rank correlation of rs = 0.65. The categorization of the RTS-score in four risk groups showed correct classification to the four skin types of Fitzpatrick in 75% of the cases. Other methods for the assessment of sun sensitivity displayed varying agreements with the RTS-score. Conclusion The RTS questionnaire showed a sufficient internal consistency. There is a good convergent validity between the RTS-score and the Fritzpatrick classification avoiding shortcomings of the prevailing standard. The questionnaire represents a simple, reliable and valid instrument for the assessment of sun sensitivity. The questionnaire can be useful for epidemiological studies as well as for skin cancer prevention. Further development and standardization of sun sensitivity assessments is necessary to strengthen the evidence of epidemiological studies on causal factors of melanoma and other skin cancers.

Abstract
OBJECTIVE To estimate the separate effects of sunlamp and tanning bed device use on melanoma risk. METHODS Population-based case-control study of 423 cases of melanoma and 678 controls in the state of New Hampshire. Exposure data, including sunlamp and tanning bed use, were collected by telephone interview. Associations were evaluated using logistic regression analyses. RESULTS About 17% of participants ever used a sunlamp, and most use (89%) occurred before 1980. The OR was 1.39 (95% CI 1.00-1.96) for ever using a sunlamp, 1.23 (95% CI 0.81-1.88) for those starting sunlamp use <20 years, and 1.71 (95% CI 1.00-2.92) for those starting >/=20 years. Data suggested increasing risk with number of sunlamp uses and with duration of use (tests of trend p = 0.02). The overall prevalence of tanning bed use was 22% and most use (83%) occurred after 1980. The OR was 1.14 (95% CI 0.80-1.61) for ever using a tanning bed; there was no evidence that risk increased with frequency or duration of use. The OR was 1.96 (95% CI 1.06-3.61) for having used both devices. CONCLUSION Results suggest a modest association between sunlamp use and melanoma risk, and increasing risk with greater frequency and duration of use. No association with tanning bed use was found, but sufficient lag time may not have elapsed to assess a potential effect.

Abstract
BACKGROUND Exposure to ultraviolet radiation (UVR) results in a darkening of the skin known as tanning. Recently, it has been shown that tanning is a response to UVR-induced DNA damage and represents the skin's efforts to protect itself against further injury. Despite the link between UVR and cutaneous malignancy, people continue to pursue tanning from natural and artificial sources. This trend is reflected in the exponential rise in skin cancer incidence. OBJECTIVE The objective of this study was to review our current understanding of the factors controlling the tanning response and the relationship to cutaneous carcinogenesis, as well as the impact that the multibillion dollar tanning industry has had on the practice of dermatology. MATERIALS AND METHODS Extensive literature review was conducted in subjects related to tanning and the relationship to cutaneous malignancy. RESULTS Our knowledge of tanning and its effects on the skin has increased tremendously. It is clear that tanning contributes to the development of skin cancer. Despite this information, the incidence of skin cancer continues to increase exponentially. CONCLUSIONS Skin cancer poses a major public health concern and tanning remains the most modifiable risk factor in its etiology. Social, economic, and legislative issues have become tightly intertwined with the complex nature of human behavior in the continued pursuit of an activity that clearly has detrimental effects on one's health.

Abstract
Background Cutaneous melanoma (CM) is a cancer usually associated with high socio-economic level in the literature. Few studies have, however, assessed this relationship by gender and site or the association between CM and rurality. Methods A major-sized historical occupational Swedish cohort comprising 2,992,166 workers was used to estimate relative risk of cutaneous melanoma, broken down by gender and anatomical site, for occupational sectors (as a proxy of socio-economic class) and rurality. To this end, Poisson models were fitted for each site in men and women, including occupational sector and town size, with adjustment for age, period of diagnosis and geographical area as possible confounding factors. Results White collar workers presented a marked increased of risk in men in all melanoma cases, as well as in trunk, upper and lower limbs. This pattern was less clear for women, in which some heterogeneity appeared, as low risks in lower socioeconomic sectors in trunk, or risk excesses in white collar workers in lower limbs did not achieve statistical significance. Males also showed significant differences in risk by rural/urban distribution, but in women this association was limited to CM of lower limb. Risk of CM of head/neck did not vary by occupational sector or town size, thus depicting a specific epidemiological profile, which proved common to both sexes. Conclusion While differences in risk between men and women could suggest greater homogeneity in UV-exposure behaviour among women, the uniform risk pattern in head and neck melanoma, present in both sexes, might support the coexistence of different aetiological pathways, related to anatomical site.

Abstract
BACKGROUND/PURPOSE Previous studies implicate sunbeds in skin cancer aetiology. Women use sunbeds considerably more than men and the relation between sunbed use and skin cancer formation may therefore be explored as a sex difference. This presupposes that the sunbathing habits and the distribution of sun vacations among men and women have not changed over the last decades. METHODS The incidence of new diagnosed cutaneous malignant melanoma (CMM), basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) per year was provided. The numbers were grouped into sex and different age groups: 0-39, 0-44, 0-49 and 0-54 years. Linear regression analyses of time vs. incidence were performed from 1977 to 1989 and from 1990 to 2002. The slopes for men and women were compared. Data on the sunbathing habits and number of sun vacations for men and women were investigated. RESULTS The sunbathing habits and the distribution of sun vacations among men and women were constant from 1992 to 2002 but women used sunbeds three to four times more frequently than men. No significant difference in slopes was found in any age group for CMM or in the period 1977-1989 for BCC. However, the slopes differed significantly in almost all age groups for BCC from 1990 to 2002 (P<or=0.05). Sufficient data for SCC did not exist. CONCLUSIONS Sunbed use was associated with BCC but not with CMM.

Abstract
BACKGROUND Sunbathing and other types of exposure to ultraviolet radiation are the major preventable risk factors for skin cancer. Due to the continued increase in incidence of melanoma in Northern Ireland, we have conducted a questionnaire survey in an attempt to gather information about sunbathing habits and other forms of ultraviolet light exposure amongst the Northern Ireland population. AIM The aim of this study was to examine the test-retest reliability of a questionnaire used in a large-scale cross-sectional population survey pertaining to sunbathing habits, use of sun screen, skin types, and frequencies of sunburn and to assess the responses given by the subjects to determine the nature of their sun-related behaviour. METHODS Thirty control subjects were randomly selected from a population control sample participating in a large case-control study investigating melanoma in the Northern Ireland population. All participants completed the interview questionnaire on two occasions, with a median of 15 days (range, 12-42 days) between interviews. We randomly chose control subjects who had been visited by the same research nurse, thus ruling out interobserver bias in the analyses. We used the test-retest method. Kappa statistics were used to calculate the association between test and retest scores of all the individual items. If the items contained within the questionnaire are reliable, then repeated measurement after a fairly short period of time should result in high within-subject repeatability. RESULTS Questions pertaining to hours spent in the sun and sun bed usage showed high reliability (kappa > 0.7). Questions about sunscreen usage showed moderately high reliability (kappa > 0.6) in all but one of the 10-year age bands and complete agreement (kappa = 1) in one age category (>50 years). CONCLUSION This questionnaire is a reliable method of assessing sun-associated behaviour identifying high-risk sun-related behaviour and misconceptions about tanning, which can be targeted for improvement in public health.

Abstract
Tanning device usage is prevalent among adolescents. Few studies have assessed the role of parental influence on children's use of indoor tanning facilities. Our objective was to determine if children's tanning device usage is affected by parental knowledge of risks of indoor tanning or by parental tanning practices. A survey was administered to 160 parents of 328 children at a general pediatrics clinic and 204 parents of 367 children at a pediatric dermatology clinic (parents n=364, children n=695). Over half of all parents and 17% of all teenagers queried had previously used tanning devices. The level of parental knowledge did not predict tanning device usage by their children. However, parental tanning device usage was associated with increased usage by children (p<0.05). Children began using tanning devices on average more than 4 years earlier than their parents. Most parents (69%) never wanted their children to use tanning devices, but only 15% of parents had discussed them with their children. Therefore, health providers can provide an important service by initiating discussions about tanning devices. Additional measures, including legislation requiring parental consent for indoor tanning, are needed to reduce tanning device usage by minors.

The present study examined theoretical mediators of a parent-based intervention on sunbathing tendencies and sunburn frequencies based on the work of Turrisi et al. [Turrisi, R., Hillhouse, J., Heavin, S., Robinson, J., Adams, M., & Berry, J. (2004). Journal of Behavioral Medicine, 27, 393-412.]. Three hundred and forty parents in two regions of the United States were educated about the dangers of risky sun behavior and how to convey information about skin cancer prevention to their children. Attitudes toward sunbathing, health beliefs, appearance beliefs, and social normative beliefs were examined and found to be significant mediators of program effects on sunbathing tendencies and sunburn frequencies. The findings are discussed with respect to maximizing the effectiveness of future skin cancer interventions with children.

Abstract
Artificial tanning, defined as deliberate exposure to ultraviolet rays produced by artificial tanning devices, is a new and emerging public health issue in Australia and globally. Epidemiological research suggests that artificial tanning may contribute to the incidence of melanoma, nonmelanoma skin cancer as well as other health problems. Given that Australia has a high incidence of skin cancer, we have undertaken a study to explore how artificial tanning has been promoted to its users. The aim was to analyze the completeness and accuracy of information about artificial tanning. A content analysis of web sites of tanning salons and distributors of tanning equipment in Australia was conducted. A total of 22 web sites were analyzed. None of the solarium operators or distributors of equipment provided full information about the risks of artificial tanning. Fifty-nine percent of web advertisements had no information and 41% provided only partial information regarding the risks of artificial tanning. Pictures with the image of bronze-tanned bodies, predominantly women, were used by all web advertisers. In light of the success of sun-safety campaigns in Australia, the findings of future epidemiological research on the prevalence of artificial tanning and sociological and anthropological research on why people utilize artificial tanning should be a basis for developing effective targeted health promotion on the elimination of artificial tanning in the country.

Abstract
Solar UV radiation is the most important environmental factor involved in the pathogenesis of skin cancers. The well known genotoxic properties of UVB radiation (290-320 nm) mostly involve bipyrimidine DNA photoproducts. In contrast, the contribution of more-abundant UVA radiation (320-400 nm) that are not directly absorbed by DNA remains poorly understood in skin. Using a highly accurate and quantitative assay based on HPLC coupled with tandem mass spectrometry, we determined the type and the yield of formation of DNA damage in whole human skin exposed to UVB or UVA. Cyclobutane pyrimidine dimers, a typical UVB-induced DNA damage, were found to be produced in significant yield also in whole human skin exposed to UVA through a mechanism different from that triggered by UVB. Moreover, the latter class of photoproducts is produced in a larger amount than 8-oxo-7,8-dihydro-2'-deoxyguanosine, the most common oxidatively generated lesion, in human skin. Strikingly, the rate of removal of UVA-generated cyclobutane pyrimidine dimers was lower than those produced by UVB irradiation of skin. Finally, we compared the formation yields of DNA damage in whole skin with those determined in primary cultures of keratinocytes isolated from the same donors. We thus showed that human skin efficiently protects against UVB-induced DNA lesions, whereas very weak protection is afforded against UVA. These observations emphasize the likely role played by the UVA-induced DNA damage in skin carcinogenesis and should have consequences for photoprotection strategies.

Abstract
BACKGROUND Malignant melanoma is the third most common skin cancer in the United States. It is commonly thought that sun exposure is causative in these tumors. Recently, however, the significance of the role of sun exposure in melanoma has come into question. Some have suggested that other factors, such as genetics, play a larger role, and that sun protection may even be harmful. OBJECTIVE AND METHODS To investigate the role of sun exposure in melanoma etiology. An extensive review of basic science and clinical literature on this subject was conducted. RESULTS Although exceptions exist, sun exposure likely plays a large role in most melanomas. The pattern of this exposure, however, is not fully known, and controversy exists, especially in the use of sunscreens. Sun exposure may interact with genetic factors to cause melanomas, and sun protective measures appear to be prudent. CONCLUSIONS The cause of melanoma is probably variable and multifactorial. Sun exposure may play a primary or supporting role in most melanoma tumors.

Abstract
The incidence of cutaneous malignant melanoma is still increasing in most light-skinned populations. Sunscreen use has been proposed for the primary prevention of melanoma. However, sunscreen use may increase time spent in the sun when users are willing to acquire a tan or to stay in the sun for a long time, which may increase melanoma risk. When sun exposure is not associated with the desire to acquire a tan or stay in the sun for a long time, sunscreen use may prevent squamous cell skin carcinoma. Sun protection should give priority to clothing and sun exposure reduction. Over the last 20 years, tan acquisition through exposure to artificial sources of ultraviolet radiation has become frequent among fair-skinned adolescents and young adults. There is accumulating evidence that sunbed use is associated with melanoma when started before approximately 30 years of age.

Abstract
Skin cancer is a large and growing problem in the United States. Sun and other ultraviolet (UV) light exposures play a key role in the development of skin cancer. Pediatricians can play an important role in counseling patients and are in a position to help educate children and their families about skin cancer. The purpose of this review is to familiarize pediatricians with the magnitude of the skin cancer problem and the evidence that ultraviolet light exposure, particularly indoor tanning, contributes to this problem. We reviewed the literature on ultraviolet light and skin cancer (based on a MEDLINE search of articles using the headings "ultraviolet light" and "skin cancer") and found that skin cancer is the most rapidly growing cause of cancer deaths in the United State. There is strong epidemiologic evidence for the relationship between UV exposure and nonmelanoma skin cancer and growing evidence for the relationship between indoor tanning and melanoma. We recommend that pediatricians counsel children and their parents about UV protection. Measures such as use of sunscreen and hats for outdoor play, both at home and in school, should be encouraged.

Abstract
Retinyl palmitate (RP), a storage form of vitamin A, is frequently used as a cosmetic ingredient, with more than 700 RP-containing cosmetic products on the U.S. market in 2004. There are concerns for the possible genotoxicity and carcinogenicity of RP when it is exposed to sunlight. To evaluate the photomutagenicity of RP in cells when exposed to ultraviolet A (UVA) light, L5178Y/Tk+/- mouse lymphoma cells were treated with different doses of RP alone/or in the presence of UVA light. Treatment of the cells with RP alone at the dose range of 25-100 microg/ml did not increase mutant frequencies (MFs) over the negative control, whereas treatment of cells with 1-25 microg/ml RP under UVA light (82.8 mJ/cm2/min for 30 min) produced a dose-dependent mutation induction. The mean induced MF (392 x 10(-6)) for treatment with 25 microg/ml RP under UVA exposure was about threefold higher than that for UVA alone (122 x 10(-6)), a synergistic effect. To elucidate the underlying mechanism of action, we examined the mutants for loss of heterozygosity (LOH) at four microsatellite loci spanning the entire chromosome 11, on which the Tk gene is located. The mutational spectrum for the RP + UVA treatment was significantly different from the negative control, but not significantly different from UVA exposure alone. Ninety four percent of the mutants from RP + UVA treatment lost the Tk+ allele, and 91% of the deleted sequences extended more than 6 cM in chromosome length, indicating clastogenic events affecting a large segment of the chromosome. These results suggest that RP is photomutagenic in combination with UVA exposure in mouse lymphoma cells, with a clastogenic mode-of-action.

Abstract
BACKGROUND Although numerous studies have evaluated risk factors associated with cutaneous malignant melanoma (CMM), no such study has been carried out in Belgium. OBJECTIVES To identify individuals who are at high risk of developing malignant melanoma in Belgium, which could enhance the efficacy of screening interventions and avoid unnecessary skin inspections. STUDY DESIGN/SETTING/SUBJECTS: We prospectively included patients who were diagnosed with invasive malignant melanoma between 1998 and 2001 at the Department of Dermatology in a case-control study. Controls were selected from the outpatient dermatology clinic. Participants were interviewed and clinically examined by a dermatologist. We asked questions concerning most known risk factors associated with malignant melanoma such as phenotypical and skin characteristics, and environmental and lifestyle exposures. To adjust for confounding variables and to estimate odds ratios (ORs) and 95% confidence intervals (CIs), a multivariate model was used. RESULTS Although sunburn in childhood and substantial occupational solar exposure were modestly, but significantly, associated with malignant melanoma risk, clinical examination yielded several stronger risk factors. In a multivariate model, which adjusted for age, gender and skin phototype, phenotypical characteristics such as skin, hair and eye colour were significantly associated with the development of malignant melanoma. In the multivariate model, people with three or more atypical naevi were at more than 10-fold risk of developing a malignant melanoma (> or = 3 atypical naevi; adjusted OR = 11.40, 95% CI = 4.79-17.53) compared to those without an atypical naevus. The presence of one or more palpable naevi on the upper extremities or having solar lentigines increased the odds of developing malignant melanoma at least twofold. CONCLUSIONS In Belgium, risk factors associated with malignant melanoma appear to be in accordance with previous studies. To assess peoples' risk profile, clinical skin examination is likely to yield the most important sporadic malignant melanoma risk factors. Therefore, focusing screening campaigns on individuals with predefined findings on skin self-examination may increase its efficacy.
