RESUMO
INTRODUCTION: Excessive sun exposure and sunburns are the main preventable causes of skin cancer. The growing popularity of outdoor sports in developed countries has motivated the objective of this work to study the risk of photoexposure and the skin cancer prevention needs of athletes in an extreme race and evaluate an intervention targeted at this population. METHODS: An observational study was conducted during the XXIII edition of the 101 km de Ronda race, which consisted of trail running and mountain biking categories. Environmental and personal dosimetry, monitoring of meteorological conditions, evaluation of the athletes' photoprotection and skin examination habits, a dermatological checkup, and a satisfaction questionnaire were performed. RESULTS: The ultra-endurance race was carried out under adverse conditions (maximum ultraviolet index (UVI) = 9.2, temperatures above 30°C, and relative humidity >35%). The mean effective erythema dose received by race athletes (n = 11) was 2959.2 ± 404.2 J/m2 , equivalent to 29.6 standard erythema doses (SED). The CHACES questionnaire (n = 1145) showed a sunburn rate of 58% and poor protective habits: 62.9% of athletes do not usually use sunscreen and 67.2% do not self-examine their skin. Actinic keratoses (4.7%) and suspicious skin cancer lesions (4.2%) were found in dermatologic screening exams (n = 170). On the satisfaction questionnaire (n = 111), this intervention was rated as excellent (95.5%). CONCLUSION: This research highlights the extreme risk of photoexposure that athletes are subjected to during ultra-endurance competitions. In the same way, it shows the need to carry out interventions aimed at the acquisition of healthy photoprotection habits and skin surveillance in this target group.

BACKGROUND: Overexposure to sunlight and sunburn are the main preventable causes of skin cancer. Outdoor sports are associated with significant levels of sunlight exposure. AIMS: We sought to quantify the sun radiation exposure received by outdoor rock climbers and assess their sun exposure habits, sun protection behaviors, attitudes, and knowledge regarding skin cancer. METHODS: From April to June 2021, outdoor rock climbers contacted via email completed an online validated self-reported questionnaire on sun related habits, behaviors, attitudes and knowledge. As a pilot trial, ten participants wore a personal dosimeter during two outdoor climbing weekends in May and November 2021. Ambient ultraviolet radiation (UVR) was also recorded. RESULTS: A total of 217 outdoor rock climbers (103 women), mean age 36.8 ± 8.8 years (range 20-70 years) and median climbing practice per week of 8 h (IQR 7.5) were studied. Two in three (65.9%) participants reported at least one sunburn event during the previous rock climbing season. Of the survey respondents, 49.3% reported using sunscreen with SPF ≥ 15, 47% wore sunglasses, and 14.3% indicated they reapplied sunscreen every two hours. The median personal UVR dose measured during the two outdoor climbing weekends analyzed was 5.2 (IQR 1.8) and 8.8 (IQR 1.1) standard erythemal doses, respectively. CONCLUSIONS: The high rates of sunburn, the elevated personal UVR measured and the clearly insufficient sun protection practices followed during rock climbing together with unsatisfactory attitudes towards tanning reveal the need to develop explicit sun protection campaigns and educational strategies to reduce the risk of skin cancer among the athletes studied.

OBJECTIVE: Overexposure to ultraviolet (UV) radiation is the main preventable cause of skin cancer. Outdoor workers, exposed to the sun for many hours throughout their working lives, are at special risk. The aim of this study is to determine occupational photoexposure and photoprotection among outdoor workers employed by a municipality in southern Spain. METHODS: Cross-sectional descriptive study focusing on outdoor workers employed by the municipality of Fuengirola (in areas such as construction, gardening, urban cleaning and beach maintenance). The participants were monitored by personal dosimetry, participated in a dermatological check-up and answered a validated questionnaire (CHACES) on their habits, attitudes and knowledge related to sun exposure. RESULTS: The median effective erythema dose of exposure to solar UV radiation during the working day (n=20) was 379.4 J/m2, equivalent to 3.8 standard erythema doses, almost 3 times higher than the recommended limits for an 8-hour workday. Skin examination (n=128) revealed the presence of actinic lentigines (79.7%), actinic keratoses (8.6%) and skin cancer (3.9%). The CHACES questionnaire (n=128) revealed a sunburn rate of 50.0%. Photoprotection practices were markedly deficient: only 16.7% of the survey respondents sought protection in the shade, 20.3% avoided exposure during the peak exposure hours and 33.1% applied sunscreen. CONCLUSIONS: This is the first study to evaluate UV radiation exposure, occupational sun protection practices, sunburn and actinic injuries of different outdoor workers in one of the sunniest regions of Spain and underlines the need for effective interventions to protect outdoor workers' health.

BACKGROUND: Overexposure to sunlight is the main cause of skin cancer. Photoprotection practices and sunburn play a crucial role in skin cancer prevention. OBJECTIVES: This study aimed to quantify the risk of sun exposure and to evaluate photoprotection practices in Spanish sailors during Olympic competitions. METHODS: Solar daily ultraviolet (UV) radiation cycle, personal UV dosimetry, photoprotection practices and sunburn checking were followed during three consecutive days of competition among sailors from the Spanish Olympic Sailing Team during a Tokyo Olympic Regatta Test Event. RESULTS: A total of 13 sailors (7 women), with mean age of 27.6 ± 4.7 years and sports experience of 17.7 ± 5.4 years, were studied. The most common phototypes were type III (53.8%) and type II (38.5%). The rate of sunburn checked was high (46.2%). The mean daily personal UV exposure received was 761.0 ± 263.6 J/m2 , 3.0 ± 1.1 minimal erythemal dose and 7.6 ± 2.6 standard erythemal dose, seven times greater than the maximum permissible UV light exposure values for an 8 h working day. The use of a T-shirt was the most common practice (94.2%), followed by the use of shade (50.2%), hat/cap (44.0%), sunglasses (26.1%) and sunscreen (11.8%). CONCLUSIONS: Olympic sailor's studies presented high levels of UV radiation received, high rate of sunburn and insufficient adherence to sun-protective behaviours (especially, to use of sunscreen) to prevent sunburn, the main cause of skin cancer. Sport Federations should develop educational campaigns addressing sun-related exposure habits and photoprotection behaviours to reduce the risk of skin cancer among these athletes.

Chronic sun exposure and sunburns are the main preventable causes of skin cancer. Due to the nature of their work, physical education teachers are at high risk for occupational skin cancer. This descriptive, cross-sectional study analyzes primary and secondary physical education teachers in Andalusia, Spain. All participants were invited to monitor their ultraviolet (UV) radiation exposure using individual biologic dosimeters and record their photoprotection practices over 3 workdays. The teachers spent an average of 2.7 h outdoors and the mean personal UV radiation exposure was 309.9 J/m2 per day, a value three times higher than international recommendations. Based on the photoprotection diary, it was determined that classes held outdoors were not scheduled outside the hours with the highest UV index and that the percentage of participants who followed the photoprotective practices of remaining in the shade or wearing a hat during outdoor lessons were less than 20% and 60%, respectively. The results on sun exposure and photoprotection practices show a need for organizational and educational intervention strategies to mitigate sun exposure and increase compliance with photoprotection measures to reduce skin cancer risk among these workers and promote early diagnosis of the disease.

Kitesurfing is one of many water sports that are growing in popularity throughout the world. In such sports, practitioners are exposed not only to direct sunlight but also to reflection from the water surface, which aggravates the impact of solar radiation on the skin. This study sought to analyse the photoprotection and photoexposure habits and knowledge of elite kitesurfers and their beliefs and attitudes in this respect. A sample of convenience of 72 male kitesurfers completed a validated questionnaire in full. By Fitzpatrick phototype, the most common classes were types I and II (69.4%). On average, kitesurfers had been practising their sport for 10.93 years, at a rate of 13.93 h per week. During the last sports season, 84.7% of respondents had suffered at least one sunburn, while 43.1% had been sunburned at least three times. The sun protection practice most commonly adopted was the use of sunscreen cream, which was used by 79.2% of respondents. Although 43.2% of respondents recognized to be worried about they might get skin cancer from the sun, 31.9% does not like using sunscreen and 44.4% like sunbathing. Regarding the respondents' knowledge of facts about sun exposure, the average rate of correct answers for the items evaluated was 66.9%. In conclusion, elite kitesurfers are potentially exposed to dangerous levels of UV radiation, which caused numerous sunburn episodes during the last sports season. It is necessary to raise these athletes' awareness of their risk of developing skin cancer and of the need to improve their sun protection and skin surveillance practices.

Sun exposure in childhood is a major risk factor for the development of skin cancer as an adult. School children spend much of their time outdoors exposed to ultraviolet radiation during recreational and sports activities. Skin cancer incidence tripled from 1978 to 2002 in Spain. Andalusia, the largest and sunniest region of Spain, lacks data on the sun protection measures taken in schools. To address this deficit, the aim of this study was to determine photoprotection practices and policies in preschools and primary schools in Andalusia. This descriptive study involved the administration of an online questionnaire completed by principals regarding school sun protection policies and practices. Preschool and primary schools were selected from the database of the Ministry of Education of the Andalusian Regional Government. Information of interest included photoprotection policies, students' sun protection knowledge, sun protection measures, relevant curricular content, and availability of shade at the school. A total of 2425 schools were contacted. Of them, 420 schools responded (17.31%), with the highest number of responses received from Malaga (23.8%) and Seville (19.5%) provinces. Of those responding, 67.1% of the schools did not have written sun protection policies. The photoprotection measures reported included mandatory use of a cap or hat (3.3%), use of sunglasses in outdoor areas (30%), and active encouragement of students to use sunscreen (50.7%). Roughly 24% of schools evaluated their shaded areas, with 52.9% reporting insufficient protection for most activities. The study results showed that photoprotection policies and practices in Andalusian schools were mostly insufficient. Given that skin cancer incidence has increased considerably over the last decade, it is important to concentrate on improving primary prevention practices. Additionally, photoprotection programs in schools have been shown to improve children's knowledge, attitudes, and habits regarding photoprotection. Thus, it is essential for Andalusian preschools and primary schools to develop policies and strategies to help reduce children's sun exposure while at school.

Non-melanoma skin cancer (NMSC), despite its low mortality, can impose a significant psychological burden on patients. The aim of the present study is to examine the evolution of the quality of life (QOL) in patients with cervicofacial NMSC during treatment. This prospective cohort study was conducted to a group of patients with cervicofacial NMSC, confirmed by skin biopsy. These patients completed the Skin Cancer Index questionnaire at the time of diagnosis and at 1 week, 1 month and 6 months after treatment began. Data for these patients' demographic characteristics and variables related to the type of tumour, the treatment received and the evolution of the condition were recorded. The study group was composed of 220 patients. At the time of diagnosis, the overall mean score for QOL was 54.1 (SD 21.9); for the social appearance component, it was 76.7 (SD 26.2), and for the emotional component, it was 23 (SD 25.1). Six months after treatment began, the overall mean score was 61 (SD19.1), that for social appearance, 85 (SD 20.6), and that for the emotional component, 27.4 (SD 26.6). All the differences were statistically significant (p < 0.05). The results obtained show that during the treatment period, it is at the time of diagnosis when patients with cervicofacial NMSC undergo the greatest deterioration in their QOL. In comparison with the findings obtained in previous studies, our population obtained lower overall scores in the questionnaires and less improvement during follow-up.

Sunburn caused by overexposure to ultraviolet radiation is the main cause of preventable skin cancer. This study aimed to describe the sun protection habits and rate of sunburns associated with the practice of cycling and to identify predictive factors of sunburn among cyclists. A descriptive observational study based on online surveys was conducted. Recruitment of participants was conducted through the Andalusian Cycling Federation (Spain). A questionnaire on behaviour, attitudes, and knowledge related to sun exposure was used. A bivariate analysis was carried out with sunburn episodes during the previous year as outcome variable, and a multivariate logistic regression model was built. Of the 1018 surveys returned, 87.6% were answered by men, mean age was 41.8 years (SD: 11.0), and 37.6% of the participants had phototype I or II. Sunburns during the previous year were reported by 45.6% (95% CI: 42.5-48.7) of the respondents. Sunscreen use was reported by 39.2%, and 61.0% did not examine their skin regularly despite the fact that 34 subjects (3.4%) reported a personal history of skin cancer. The multivariate logistic regression analysis showed that there was a negative correlation between episodes of sunburn and age, phototypes I-II, more than 2 h of sun exposure, and inconsistent use of sunscreen. Cyclists have high rates of sunburns and thus constitute a high-risk group for developing skin cancer. Educational interventions specifically aimed at this group of athletes would improve sun protection knowledge and practices, particularly the use of sunscreen.

PURPOSE: Non-melanoma skin cancer (NMSC) is the most frequent neoplasm today, worldwide. This type of tumour presents low mortality but causes a major psychosocial impact on the patient. Studies have shown that the patient's quality of life (as detected by questionnaire scores in this respect) improves as the care process advances. The main aim of the present study is to identify the factors that are related to this favourable evolution. METHODS: This descriptive cross-sectional study included patients with cervicofacial NMSC, confirmed by skin biopsy. The patients were asked to complete the Skin Cancer Index questionnaire at the time of diagnosis and subsequently at 1 week, 1 month and 6 months after treatment. Relevant demographic variables were recorded, together with information on health status and the treatment received. RESULTS: A total of 229 patients with biopsy-confirmed cervicofacial NMSC were included in the study population, and 220 completed the quality of life questionnaires at the necessary time points during the care process. Some variables-sex, education, marital status, history of anxiety or depression, tumour type, the treatment received and the VAS score in this respect-were found to have a statistically significant influence on the degree of improvement recorded in the quality of life questionnaire scores during follow-up. CONCLUSIONS: The quality of life questionnaire scores of patients with cervicofacial NMSC improve following treatment, but this progression is not homogeneous among patients. We identify the variables that are related to a greater degree of improvement on the questionnaire scales (overall, emotional and social-aesthetic).

Oral oxybutynin (OOx) is an effective and safe treatment for the treatment of hyperhidrosis (HH). However, in some patients a loss of efficacy during prolonged treatment has been observed. Analysis of these cases could enable us to identify patients susceptible to OOx tolerance. An alternative treatment might then be considered. To assess tolerance to OOx in the treatment of HH. Secondarily, to assess epidemiological data and the duration of efficacy, together with the probable causes of any loss in this respect. Retrospective study of patients who started treatment with OOx for HH during the period 2007 to 2017 and who either abandoned this treatment due to loss of efficacy or needed higher daily doses to maintain the initial efficacy. Epidemiological data were collected, the duration of the efficacy of OOx was recorded and the possible causes of loss of efficacy were considered. The development of tolerance was suspected in 18 patients (8.5%) of the 211 who had previously responded to OOx. Thirteen patients abandoned OOx due to its lack of efficacy and five had to increase the dose in order to maintain efficacy. In seven patients, tolerance to the drug appeared in the first year of treatment, while in the remaining 11, the tolerance appeared later. Most patients achieved and maintained good control of HH with long-term OOx. However, in some cases the efficacy of the drug decreases. The study analysis did not produce findings enabling us to predict a loss of treatment efficacy.

Beach users and outdoor workers in resort areas are major risk groups for skin cancer, and therefore seaside hotels constitute a strategic area in which to conduct awareness-raising campaigns and interventions. The main aim of the present study is to describe habits, attitudes and knowledge related to sun exposure, the sunburn events experienced and potentially malignant skin lesions observed among hotel staff and guests recruited during a skin cancer prevention campaign at seaside hotels in the western Costa del Sol (southern Spain). This descriptive cross-sectional study was conducted at four seaside hotels in the western Costa del Sol. An 8-day awareness-raising campaign on skin cancer was conducted for hotel guests and staff, who were invited to complete a questionnaire about their habits, attitudes and knowledge regarding photoprotection, and to receive a comprehensive skin examination. The questionnaire on habits, attitudes and knowledge related to sun exposure was completed by 542 participants. The most common photoprotection practice was the use of sunglasses (79.3%). Potentially dangerous lesions were identified in 39 persons (14%). In addition, 94.0% reported having gained new knowledge, 89.6% had changed their attitudes towards sun tanning and 94.7% intended to improve their photoprotection practices in the future. Seaside hotels are an optimal scenario for conducting studies aimed at skin cancer prevention and reduction. Further studies should be carried out in other geographical areas to confirm our results, to evaluate the costs and benefits of such interventions and determine their long-term impact on health.

BACKGROUND: Photodynamic treatment with methyl aminolevulinate (MAL-PDT) is considered an effective and highly recommended treatment for Bowen's disease. However, its long-term efficacy remains to be established, as significant differences have been reported in this respect. OBJECTIVE: The aim of the present study was to describe the results of a retrospective analysis of patients with Bowen's disease treated with MAL-PDT during the period 2006-17 at the Costa del Sol Hospital (Marbella, Spain). MATERIAL AND METHODS: This study is based on a retrospective descriptive analysis of the clinical records of patients treated with MAL-PDT from June 2006 to September 2017. The analysis was based on calculating the mean and standard deviation values for the quantitative variables, and frequency distributions for the qualitative ones. The survival curves were plotted by the Kaplan-Meier method, and the log-rank test was used to assess differences in survival between groups. A cox regression analysis was performed to clarify the significant prognostic factors. RESULTS: A total of 537 tumours with histologically confirmed Bowen's disease were treated with MAL-PDT. Recurrence-free survival at one year was 88%, and at 5 years, 71%. Tumour size >300 mm2 (≥21 mm in diameter P = 0.019), its location in the upper extremities (P = 0.029) and patient's age <70 years (P = 0.028) were all associated with an increased risk of recurrence. LIMITATIONS: Given the retrospective design of our study, the possible existence of information bias cannot be ruled out. CONCLUSIONS: Although it is an appropriate treatment option for patients with Bowen's disease, MAL-PDT presents a risk of recurrence of almost 30% at 5 years. Larger lesions (>300 mm2 ; ≥21 mm in diameter) are more likely to recur than smaller ones. Therefore, appropriate selection is needed of the tumour to be treated, and prolonged follow-up should be provided.

Most studies of oral oxybutynin (OOx) for the treatment of hyperhidrosis (HH) have assumed a stable treatment protocol, without taking into account adverse effects (AE) or seasonal variations in temperature. The objective is to evaluate adjusting the dose of OOx according to the time of year. Prospective study of patients who began OOx for HH between 2007 and 2017, and maintained treatment for at least 1 year, with a progressively increasing dose was performed. All patients were recommended to vary the dose of medication according to the time of year. Baseline epidemiological data, the response to treatment and AE were analyzed. About 122 patients were included (average age of 33.8 years). Up to 60.7% varied the dose. Significantly better results were obtained in the group that varied the dose. Twenty patients suspended the treatment in winter. Among them the adjusted OR was 3.04 (95% CI 1.24-7.45) for an excellent response. The frequency of AE was 74.6% with no differences among groups. Most patients are able to control their HH without requiring the same dose of OOx throughout the year. Given that the possible AE of OOx are dose-dependent, it seems reasonable to vary it according to the time of year.

BACKGROUND: Painful sunburns at any age are one of the main risk factors for skin cancer. OBJECTIVES: To determine the prevalence and predictors of sunburn among beachgoers. METHODS: A cross-sectional health survey was conducted at the beach during the summer. Adults >18 years with an understanding of Spanish were interviewed using a questionnaire about behaviours, attitudes and knowledge related to sun exposure at the beach. A descriptive analysis was performed, and a log-binomial regression model was used to determine predictors of sunburn. RESULTS: The survey was completed by 1054 beachgoers, with a mean age of 43.8 (SD: 18.7) years, 61.2% women, skin phototypes i (13.6%), ii (22.3%), iii (34.0%) and iv (30.2%). 46.9% of responders reported at least one painful sunburn during the previous summer. Age, sex, education, skin phototype, midday sun exposure, sun protection habits, attitudes towards tanning and knowledge about skin cancer were identified as independent predictors of sunburn. CONCLUSIONS: It is necessary to develop photoprotection campaigns aimed at beachgoers, particularly in young people, men, those with skin phototypes I-III and secondary or university education. Educational strategies should be aimed at discouraging sun exposure at midday, changing attitudes towards tanning and improving knowledge about skin cancer.

Radiotherapy is a widely recognised treatment for non-melanoma skin cancer. We report three cases of radiation-induced skin ulcers in which hyperbaric oxygen therapy was administered in 90-min sessions, 5 days a week at 2.4 absolute atmospheres in a multiplace hyperbaric chamber. Hyperbaric oxygen therapy is an outpatient treatment that does not displace other classical treatments and may be used as an adjunct therapy.

BACKGROUND/OBJECTIVES: Although many treatments are available to address hyperhidrosis, the results are not always satisfactory. The aim of the study was to assess the effectiveness, optimal dosage regimen and long-term safety of oral oxybutynin in the treatment of hyperhidrosis. METHODS: A retrospective review was performed on 110 patients who underwent treatment for hyperhidrosis between February 2007 and December 2013. Their response to treatment was evaluated using the hyperhidrosis disease severity scale at baseline, 3 and 12 months. Additionally, the safety and effectiveness of different up-dosing and fixed-dose regimens were compared. RESULTS: After 3 months of treatment, 87 of the 110 patients (79%) had responded (63%), which was considered excellent. After 12 months, 63 patients (62%) continued to respond, and the response was considered excellent in 50%. Nine patients were lost to follow up between month 3 and 12. In total, 77 and 70% of the patients who responded at 3 and 12 months, respectively, reported mild adverse events. No serious adverse events were observed. Treatment adherence was significantly higher among patients following the individualised up-dosing regimen. CONCLUSION: Oral oxybutynin may be an effective and safe option for the long-term treatment of hyperhidrosis. To improve treatment adherence, oxybutynin dosing regimens should be individualised on the basis of the patient's tolerance and response.

Adolescents are considered a risk group for the development of skin cancer in later life due to their high rates of sunburn. The aim of this study is to evaluate the association between attitudes to sun exposure and the sociodemographic characteristics of adolescents, their habits, practices and knowledge. As a secondary goal, we describe the magnitude and sign of the correlations between these attitudes. Cross-sectional study of adolescent students from 12 secondary schools in southern Spain, the subjects were asked to complete the 'Beach Questionnaire'. This instrument examines four dimensions of attitudes, with standardised scores of 0-100, related to the sun, sun tanning, sun protection and sun cream. The higher the score, the more positive the attitude. The study population was composed of 270 adolescents. The highest scores were obtained for attitudes towards sun protection practices (mean 66.2; SD 18.6) and towards sun tanning (mean 64.2; SD 21.1). The lowest scores were obtained for attitudes towards using sun cream (mean 50.1; SD 24.6). Significant differences were found for all four attitudes, with a positive sign for the relationship between the number of days of sun exposure and a higher score for attitudes towards sunbathing (27.3 points difference between response extremes) and for attitudes towards suntanning (20 points difference). Favourable attitudes towards sunbathing and sun tanning have most influence on inadequate habits of sun exposure and deficient measures of sun protection. Adolescents should be considered a priority group for targeted interventions to improve sun protection behaviour.
