Positive impact of Distintivo Soludable on implementation of sun protection policies and practices in schools of Andalusia, Spain.

The incidence of skin cancer is increasing worldwide even though its main risk factor is preventable. This study evaluated the impact of the Distintivo Soludable pilot intervention on implementation of photoprotection policies and practices in preschool and primary schools in Andalusia, Spain. We completed two rounds of a Sun Protection Policies and Practices Survey (SPPPS) nine months apart. At baseline, 67 Andalusian schools earned a median score of 3/12 points (range 0-8; IQR: 2). Ten schools involved in Distintivo Soludable intervention group significantly increased their scores from 4 to 7.5/12 points (p = 0.014). We also detected a modest positive effect in 57 control group schools, an increase from 2 to 3 points (p = 0.002). This pilot study demonstrated that the main achievement of the Distintivo Soludable intervention was implementation of organizational policies regarding sun protection, an essential starting point for establishing positive attitudes toward sun protection in school communities.

Sun exposure practices, attitudes and knowledge among students and teachers at a University School of Health Sciences in Ecuador.

Skin cancer incidence is increasing worldwide. Late adolescence and young adulthood are fundamental stages of life to acquire good sun exposure practices, regarding both personal involvement in skin cancer prevention and being a role model for others, especially in a health education environment. This descriptive cross-sectional study is based on the validated CHACES questionnaire to study sun exposure and photoprotection behavior among students and teachers at the School of Health Sciences in the National University of Chimborazo, Riobamba (Ecuador). University members (814 students (89.8 %) and 93 teachers (10.2 %)) were studied, with a predominance of females and light-skin phototypes in both groups. Similar results were obtained regarding sun exposure, with higher recreative exposure in the teachers' group and higher occupational exposure in students. However, students significantly showed lower avoiding midday sun (41.9 % vs 60.9 %), and lower use of sunglasses (10.1 % vs. 41.6 %). Attitudes towards the sun and photoprotection knowledge issues were also equivalent between students and teachers (6.1/10 vs 6.2/10). Students' sunburn rate last year reaches 88.4 % and 52.7 % in teachers (p < 0.001). Using a multivariable logistic regression model, we identified risk factors associated with a greater risk of sunburn in our population. This study highlights areas to be improved regarding knowledge, attitudes and, especially, practices of photoprotection, among students and teachers at the University of Chimborazo. These results point out that awareness-raising campaigns should be implemented to reduce sunburns, morbidity and mortality of skin cancer in this environment.

Hábitos, actitudes y conocimientos sobre la exposición solar de corredores de fondo en la Costa del Sol / Sun Exposure and Long-Distance Runners on the Spanish Costa del Sol: Habits, Attitudes, and Knowledge

A nivel dermatológico, la elevada exposición solar a radiación ultravioleta asociada a la práctica de actividades deportivas al aire libre, máxime en actividades recreativas de larga duración como son los corredores de fondo, aumenta el fotoenvejecimiento de la piel y la incidencia de cáncer de piel. El propósito del estudio fue evaluar los hábitos, actitudes y conocimientos sobre la exposición solar de corredores de fondo de nuestra comunidad. Se realizó un estudio transversal descriptivo mediante encuesta con un muestreo de conveniencia entre aquellos participantes de las medias maratones populares de Fuengirola y Marbella celebradas en el mes de septiembre del año 2016. En la muestra evaluada se ha hallado una intensa exposición solar realizando actividades al aire libre, asociado ello a una prevalencia de quemaduras solares elevada (uno de cada 2 corredores) (AU)

Exposure to UV radiation during the practice of sports in the open air is especially high in sustained recreational activities such as long-distance running. UV exposure increases skin photoaging and the incidence of skin cancer. This study aimed to describe habits and attitudes related to sun exposure among long-distance runners in our area of southern Spain as well as to evaluate the runners’ knowledge of exposure. A cross-sectional descriptive study was designed to survey a convenience sample of participants in half marathons in Fuengirola and Marbella in September 2016. We found a high level of sun exposure among participants in this outdoor activity. The prevalence of sunburn was also high, experienced by half of the runners surveyed (AU)

Photoprotection habits, attitudes and knowledge among school communities in the Costa del sol (Spain).

BACKGROUND: Scholar photoprotection campaigns are among the most effective strategies for preventing skin cancer. Analysis of the target population constitutes a valuable starting point for the implementation of primary prevention strategies. Our aim is to study photoprotection habits, attitudes and knowledge among a Spanish school community. METHODS: Descriptive cross-sectional study targeting schoolchildren, parents and teachers at 20 schools in the area of the Costa del Sol Health Agency in southern Spain. Two population-specific, validated questionnaires were used: the CHRESI (for children aged 0-10 years) and CHACES Questionnaire(for adults and adolescents aged > 11 years). We collected demographic data, skin colour, skin phototype, sunburn episodes, sun exposure and photoprotection practices, attitudes and knowledge. RESULTS: 1728 questionnaires were analyzed (22% parents, 14.5% teachers, 44.8% adolescents and 18.6% children). The average ages were 8 years (children), 16 years (adolescents), 39 years (teachers) and 42 years (parents). Globally, the predominant features were: male sex (52%), Spanish nationality (92%) and phototypes II-III (61%). Children, followed by adolescents, reported the highest exposure to the sun, both in frequency and in duration. Adolescents had the higher rate of sunburn (75%), followed by parents/teachers (54.1%) and children (44.1%). Children and their parents were the most likely to adopt photoprotection measures, while adolescents presented more risky attitudes. Knowledge regarding photoprotection was acceptable (6.9/10). CONCLUSIONS: This study highlights the need to improve photoprotection knowledge, habits and attitudes among our target population. Scholars, parents and teachers in our area should be addressed in campaigns to promote healthy sun exposure habits, thus reducing skin cancer-related morbidity and mortality in this region.

Validación de un cuestionario para el estudio sobre hábitos, actitudes y conocimientos en fotoprotección en la población adultojuvenil: «cuestionario CHACES» / Validation of a Questionnaire Designed to Study Knowledge, Attitudes, and Habits Related to Sun Exposure Among Young Adults: The CHACES Questionnaire

Las campañas escolares de prevención del cáncer cutáneo han demostrado ser eficaces y costo-efectivas. Su éxito depende de un adecuado diseño, basado en la encuestación previa de la población diana (alumnos, profesores y padres). Sin embargo, son escasos los cuestionarios validados en castellano que estudien hábitos y conocimientos sobre exposición solar en infancia, y nulos en la población adultojuvenil. OBJETIVOS: Elaborar y validar un cuestionario que explore las conductas relacionadas con la exposición solar en población adultojuvenil. METODOLOGÍA: Se elaboraron 2 cuestionarios, dirigidos a población adulta (mayor de 18 años) y juvenil (11-17 años), incluyendo datos demográficos, color de piel, fototipo, quemaduras solares, prácticas, actitudes y conocimientos relacionados con la exposición solar. Tras el pilotaje y análisis de validez de contenido, se diseñó un estudio de validación en 2 fases: I) Análisis de la validez y consistencia interna de los ítems (estudio trasversal sobre 1.482 adolescentes-adultos, con estudio de validez de constructo [mediante análisis factorial exploratorio] y de consistencia interna [alfa de Cronbach]), II) Estudio de la estabilidad (test-retest sobre 39 sujetos). RESULTADOS: El pilotaje demostró la validez de contenido de sendos cuestionarios. El análisis de los componentes principales reveló 2 componentes en cada dimensión estudiada, explicando más del 50% de la varianza. Todos los ítems mostraron buena correlación entre ellos. Se demostró validez en la fase i (coeficiente alfa de Cronbach entre 0,45-0,8, excepto el área de conocimientos [0,335]) y estabilidad en la fase ii (acuerdo absoluto > 60%). CONCLUSIONES: El cuestionario posee propiedades psicométricas que lo hacen válido y fiable para estudio de hábitos, actitudes y conocimientos con relación al sol en población escolar adultojuvenil

Skin cancer prevention campaigns in schools have been shown to be both effective and cost-effective. The success of such programs depends on the use of an appropriate design informed by a prior survey of the target population (pupils, teachers, and parents). There are, however, very few validated Spanish-language questionnaires designed to study the habits and knowledge of this population with respect to sun exposure in childhood and none designed for use with a young adult population. OBJECTIVES: To construct and validate a questionnaire designed to explore sun exposure behaviors in a young adult population. METHODOLOGY: Two questionnaires were developed, one for adults (18+) and the other for young adults (11-17); both included demographic information, skin color, Fitzpatrick skin type, and history of sunburn as well as questions on knowledge, attitudes and practices related to sun exposure. The content was then piloted and its validity analyzed. The subsequent validation study was divided into 2 phases as follows: 1) analysis of the validity and internal consistency of the items in a cross-sectional study of 1,482 adults and adolescents, using exploratory factor analysis to test construct validity and Cronbach α to measure internal consistency; and 2) evaluation of test-retest reliability in 39 individuals. RESULTS: The pilot study demonstrated the content validity of both questionnaires. Principal component analysis revealed that 2 components in each of the dimensions studied accounted for over 50% of the variance. A good correlation was found between the items studied. Validity was demonstrated in the first phase of the analysis with a Cronbach α of between 0.45 and 0.8 for all components except knowledge (0.335). In the second phase, test-retest reliability was demonstrated (absolute agreement > 60%). CONCLUSIONS: The psychometric properties of the questionnaire make it a valid and reliable tool for the study of knowledge, attitudes, and habits with respect to sun exposure in the young adult school population

Todas las recomendaciones mostraron un alto nivel de acuerdo, tanto en la valoración de la importancia y factibilidad como en la categorización de los niveles de complejidad. Conclusión: Se trata del primer distintivo de fotoprotección escolar que se desarrolla en nuestro país. Se necesitan estudios que evalúen el grado de aceptación de la estrategia y su impacto en los hábitos de fotoprotección de los escolares

Introduction: Sun exposure during childhood is the main risk factor for skin cancer in later life. School-based sun protection policies and practices have proven to be the most effective and cost-effective strategies for preventing skin cancer. Objective: To develop a sun protection accreditation program known as «Soludable» (a play on the Spanish words sol [sun] and saludable [healthy]) to objectively identify schools that actively promote sun protection behaviors among students. Methods: The consensus method used was a 2-round Delphi technique with input from a panel of experts. We then calculated the median scores for the importance and feasibility of each of the recommendations proposed and the level of complexity assigned to each recommendation by counting the percentage of experts who chose each difficulty category. Results: The resulting accreditation model consists of 14 recommendations with corresponding evaluation criteria divided into 7 domains: 1) organizational leadership (5 recommendations), 2) effective communication (2 recommendations), 3) structural elements (2 recommendations), 4) training of professionals (1 recommendation), 5) school curriculum (1 recommendation), 6) behavioral models (2 recommendations), and 7) student habits (1 recommendation). A high level of agreement among experts was observed for all recommendations, in terms of both their perceived importance and feasibility and their categorization by levels of complexity. Conclusions: This is the first sun protection accreditation program developed for Spanish schools. Studies are needed to evaluate how this program is received and how it affects students' sun protection behaviors

Utilidad de la ecografía cutánea en la clasificación de subtipos de los carcinomas basocelulares primarios / Usefulness of high-frequency ultrasound in the classification of histologic subtypes of primary basal cell carcinoma

INTRODUCCIÓN: La biopsia incisional puede fallar en la correcta catalogación de subtipos histológicos de carcinoma basocelular (CBC). La ecografía (ECO) cutánea es una herramienta diagnóstica útil en el diagnóstico y manejo de este tumor. OBJETIVOS: El objetivo principal fue evaluar la utilidad diagnóstica de la ECO frente a la biopsia punch en la correcta clasificación del patrón histológico de infiltración de los CBC primarios. Los objetivos secundarios fueron: evaluar si el rendimiento diagnóstico de la ECO frente a la biopsia incisional guardaba relación con el tamaño tumoral y con formas de CBC simples frente a formas mixtas. MÉTODOS: Estudio observacional prospectivo de los casos de CBC primarios atendidos en el Servicio de Dermatología del Hospital Costa del Sol (Marbella) entre octubre de 2013 y mayo de 2014. Previamente a la extirpación quirúrgica se realizó una ECO cutánea (Dermascan C©, sonda lineal, 20 Mhz) y una biopsia punch. Se valoró el porcentaje de acuerdo absoluto y rendimiento diagnóstico (sensibilidad, especificidad, valor predictivo positivo [VPP] y valor predictivo negativo [VPN]) para resultados globales y parciales entre ECO y punch frente al gold estándar (biopsia escisional por cortes seriados). RESULTADOS: Se incluyeron 156 casos. La tasa de concordancia diagnóstica global de la ECO fue del 73,7% (sensibilidad: 74,5%, especificidad: 73%) vs. 79,9% (sensibilidad: 76%, especificidad: 82%) para el punch. En el análisis individual destaca para el CBC superficial un VPP para la ECO del 93,3% frente al 92% para el punch. En el análisis por tamaño tumoral la ECO incrementó el porcentaje de acuerdo absoluto del 70,4 al 77,3% (área 40 mm2 vs. área > 40 mm2) manteniendo el VPN constante para ambos subgrupos (82%). Para la biopsia punch, el porcentaje de acuerdo absoluto pasó del 86,4 al 72,6%. CONCLUSIONES: La ECO cutánea muestra una especial utilidad para descartar la presencia de invasividad, para el diagnóstico de formas superficiales simples y para la correcta catalogación de CBC de área mayor a 40 mm2

INTRODUCTION: Incisional biopsy may not always provide a correct classification of histologic subtypes of basal cell carcinoma (BCC). High-frequency ultrasound (HFUS) imaging of the skin is useful for the diagnosis and management of this tumor. OBJECTIVES: The main aim of this study was to compare the diagnostic value of HFUS compared with punch biopsy for the correct classification of histologic subtypes of primary BCC. We also analyzed the influence of tumor size and histologic subtype (single subtype vs. mixed) on the diagnostic yield of HFUS and punch biopsy. METHODS: Retrospective observational study of primary BCCs treated by the Dermatology Department of Hospital Costa del Sol in Marbella, Spain, between october 2013 and may 2014. Surgical excision was preceded by HFUS imaging (Dermascan C©, 20-MHz linear probe) and a punch biopsy in all cases. We compared the overall diagnostic yield and accuracy (sensitivity, specificity, positive predictive value [PPV], and negative predictive value [NPV]) of HFUS and punch biopsy against the gold standard (excisional biopsy with serial sections) for overall and subgroup results. RESULTS: We studied 156 cases. The overall diagnostic yield was 73.7% for HFUS (sensitivity, 74.5%; specificity, 73%) and 79.9% for punch biopsy (sensitivity, 76%; specificity, 82%). In the subgroup analyses, HFUS had a PPV of 93.3% for superficial BCC (vs. 92% for punch biopsy). In the analysis by tumor size, HFUS achieved an overall diagnostic yield of 70.4% for tumors measuring 40 mm2 or less and 77.3% for larger tumors; the NPV was 82% in both size groups. Punch biopsy performed better in the diagnosis of small lesions (overall diagnostic yield of 86.4% for lesions 40 mm2 vs. 72.6% for lesions > 40 mm2). CONCLUSIONS: HFUS imaging was particularly useful for ruling out infiltrating BCCs, diagnosing simple, superficial BCCs, and correctly classifying BCCs larger than 40 mm2

Responsiveness of the Spanish Version of the "Skin Cancer Index".

Background. Skin Cancer Index (SCI) is a specific questionnaire measuring health related quality of life (HRQL) in patients with cervicofacial non-melanoma skin cancer (CFNMSC). The original scale has recently been adapted and validated into Spanish. Objectives. Evaluate the responsiveness of the Spanish version of SCI. Methods. Patients with CFNMSC candidate for surgical treatment were administered the questionnaire at time of diagnostic (t0), 7 days after surgery (t1), and 5 months after surgery (t2). The scale and subscales scores (C1: social/appearance, C2: emotional) were then evaluated. Differences between t0-t1, t1-t2, and t0-t2 were determined and a gender-and-age segmented analysis was performed. Results. 88 patients, 54.8% male, mean age 62.5 years, completed the study. Differences between t0-t1 and t1-t2 scores were statistically significant (p < 0.05). The lowest values were found at time of diagnosis and postsurgery. Women and patients under 65 years showed the lowest values at the three times. Limitations. Concrete geographic and cultural area. Clinical and histological variables are not analysed. Conclusions. Our results confirm responsiveness of the Spanish version of the SCI. Further development of the instrument in Spanish-speaking countries and populations will make it possible to extend worldwide research and knowledge horizons on skin cancer.

Siliconomas axilares en pacientes con melanoma / Axillary Silicone Granulomas in Patients With Melanoma

Durante el seguimiento de pacientes con melanoma podemos detectar lesiones subcutáneas cuyo principal diagnóstico diferencial son las metástasis en tránsito o las adenopatías metastásicas. Se describen 2 mujeres con melanoma portadoras de prótesis mamarias que presentaron durante su seguimiento lesiones subcutáneas palpables en la región axilar. El estudio ecográfico puso de manifiesto en ambos casos la existencia de imágenes hiperecogénicas difusas en «tormenta de nieve» localizadas en el tejido subcutáneo. En estos casos la ecografía se posiciona como herramienta diagnóstica fundamental para el despistaje de procesos relacionados con el melanoma, como las metástasis en tránsito o las adenopatías metastásicas

Subcutaneous lesions may be detected during follow-up of patients with melanoma. The main entities that should be contemplated in the differential diagnosis in such cases are in-transit and regional lymph node metastases. We describe 2 cases of women with breast implants who developed palpable subcutaneous lesions in the axillary region during follow-up of melanoma. In both cases, the ultrasound study showed diffuse hyperechoic signals forming the characteristic snowstorm sign in the subcutaneous tissue. Ultrasound proved to be a key diagnostic tool for ruling out melanoma-related disease, such as in-transit metastases and regional lymph node metastases

Utilidad del colgajo paramediofrontral en cirugía reconstructiva nasal: estudio retrospectivo de una serie de 41 pacientes / Usefulness of the Paramedian Forehead Flap in Nasal Reconstructive Surgery: A Retrospective Series of 41 Patients

INTRODUCCIÓN: La pirámide nasal, área de difícil reconstrucción quirúrgica, constituye una localización predilecta del cáncer cutáneo no melanoma. La cirugía oncológica a menudo origina defectos cutáneos extensos, con la participación ocasional del cartílago subyacente y de la mucosa nasal. Nuestro objetivo es describir nuestra experiencia en el uso del colgajo paramediofrontal en la reconstrucción de defectos nasales. METODOLOGÍA: Estudio retrospectivo de pacientes consecutivos en los que se empleó un colgajo paramediofrontal para la reconstrucción de defectos quirúrgicos nasales (julio de 2004-marzo de 2011). Se describen aspectos clinicoepidemiológicos, características de la técnica quirúrgica, complicaciones, procedimientos secundarios y resultados cosméticos. RESULTADOS: Se incluyen 41 pacientes, con edad media de 67 años (SD: 10,36) y de predominio masculino (2,4:1). Los factores de riesgo asociados fueron diabetes (27%), factores de riesgo cardiovascular (49%) y hábitos tóxicos (19,5%). Los defectos de sustancia eran mayoritariamente distales (80%) y no penetrantes (78%), con un tamaño medio de 21,6mm (SD: 6,78). Un 14,6% de los pacientes presentaron complicaciones posquirúrgicas precoces y un 31,7% secuelas tardías (22% abultamiento del colgajo y 19% transposición de pelo), requiriéndose técnicas de refinamiento secundario en el 19,5% de los pacientes. Los resultados cosméticos se consideraron mayoritariamente aceptables/excelentes (90,2%). DISCUSIÓN: El colgajo paramediofrontal es un colgajo versátil, que proporciona características similares en color y textura a la piel de la pirámide nasal. Su pedículo vascular seguro garantiza su viabilidad, así como la de otros tejidos, cuando se utiliza en combinación con injertos condromucosos o condrocutáneos. Para la obtención de resultados óptimos pueden requerirse procedimientos de revisión secundarios

INTRODUCTION: Surgical reconstruction of the external nose, a common site for nonmelanoma skin cancer, is difficult. Oncologic surgery often leaves large skin defects, occasionally involving the underlying cartilage and nasal mucosa. We describe our experience with the paramedian forehead flap for reconstruction of nasal defects. METHODOLOGY: We performed a retrospective study of consecutive patients in whom a paramedian forehead flap was used to repair surgical defects of the nose between July 2004 and March 2011. We describe the clinical and epidemiologic characteristics, the surgical technique, complications, secondary procedures, and cosmetic results. RESULTS: The series comprised 41 patients with a mean (SD) age of 67 (10.36) years. The majority were men (male to female ratio, 2.4:1). Associated risk factors included diabetes in 27% of patients, cardiovascular risk factors in 49%, and smoking or drinking in 19.5%. The tissue defects were distal in 80% of cases and nonpenetrating in 78%. The mean (SD) diameter was 21.6 (6.78) mm. Early postoperative complications occurred in 14.6% of patients and late complications in 31.7% (trap door effect in 22% and hair transposition in 19%), with a need for Readjustment in a second operation was needed in 19.5% of patients. The cosmetic results were considered acceptable or excellent in 90.2% of cases. DISCUSSION: The paramedian forehead flap is versatile and provides skin of a similar color and texture to that of the external nose. It has a reliable vascular pedicle that guarantees the viability not only of the flap but also of other tissues that may be used in combination, such as chondromucosal or chondrocutaneous grafts. Revision of the technique in a second operation may sometimes be required to achieve an optimal result
