RESUMO

Introducción: La exposición regular o prolongada a la luz solar se asocia a tasas más altas de cáncer de piel. El modelo transteórico del cambio de comportamiento (TTM) se ha utilizado con eficacia para explicar el patrón de adquisición y el cese de una variedad de comportamientos que potencialmente ponen en riesgo la salud. Éste consta de etapas del cambio denominadas de precontemplación (no pensado en el cambio), contemplación (considerando seriamente cambiar) y acción (inicio manifiesto del cambio de conducta). Objetivo: Evaluar según TTM la etapa de cambio en que se encuentra una muestra de universitarios y su correlación a sus hábitos de fotoexposición. Pacientes y métodos: Estudio prospectivo en 50 universitarios, a los cuales se les efectuó un cuestionario sobre conductas de fotoprotección y un cuestionario de disposición a la modificación de conductas de fotoprotección (RASP-B). Resultados: De los 50 universitarios, un 58 por ciento fueron mujeres, la edad media fue de 20 años y sus fototipos fueron 22 por ciento tipo II, 40 por ciento tipo III y 38 por ciento tipo IV. Un 68 por ciento reportaron el uso de fotoprotectores en las vacaciones en caso de exposición solar, sólo el 22 por ciento se lo reaplicaban y un 78 por ciento no usaban fotoprotector durante el resto del año. Un 48 por ciento de los universitarios estaban en etapa de acción , 18 por ciento en contemplación y 34 por ciento en precontemplación. Los universitarios en etapa de acción se asociaron a mayor uso de fotoprotectores (p=0.028), mayor uso de elementos de barrera (p=0049), menor exposición solar entre las 11 am y 3 pm (p=0019) y menor frecuencia de quemaduras solares con ampollas (p=0.02). Conclusión: La determinación de la etapa de disposición a cambiar los comportamientos de protección solar permite la planificación y la ejecución de intervenciones eficaces dirigidas a cada una de ellas que puedan ayudar a aumentar el nivel individual de fotoprotección (etapa de acción).


Introduction: Regular or prolonged sun ligth exposure is associated with higher rates of skin cancer. The transtheorical model (TTM) of behavior change has been effectively used to explain the adquisition and ending pattern of a variety of potential healththreatening behaviors. This model has stages of change called precontemplation (not thinking about change), contemplation (seriously considering changing) and action (manifest onset of behavioral change). Objective: to evaluate according to the TTM the stage of change found on a group of university students and to relate it to their habits of sun light exposure. Patients and methods: Cross sectional study in 50 university students which were evaluated through a questionnaire of sun-protective behavior and a questionnaire of sun-protective behavior (RASP-B). Results: Of the 50 university students, 58 percent were women, the mean age was 20 and their phototype were 22 percent type II, 40 percent type III and 38 percent type IV. A 68 percent reported the use of sunscreen on vacations, only 22 percent re-applied it and 78 percent did not use any sunscreen during the rest of the year. A 48 percent of university students were in action stage, 18 percent in contemplation and 34 percent in precontemplation. The student in action stage were associated with more use of sunscreen (p=0,028) and barrier elements (p=0,049), less sun exposure between 11 am and 3 pm (P=0,019) and lower frequency of sunburn with blisters (p=0.02). Conclusion: Determining the stage of readiness to alter sun-protective behavior allows for effective planning of interventions that can help increase the individual level of sun protection (action stage) which may decrease the probably of skin cancer.

RESUMO

Background: Ultraviolet light exposure has a pathogenic effect on the development of skin cancer, whose prevalence increases worldwide. In Chile and the rest of the world, preventive educational campaigns are carried out to change high risk sun exposure behaviors. Aim: To study the behavior of the Chilean population towards skin cancer prevention and to identify erroneous preventive practices and concepts. Material and methods: A survey containing 17 questions about sun exposure behaviors, photoprotective measures and knowledge about ultraviolet radiation and skin cancer was used. It was applied during January and February 2004, to 1,143 subjects (mean age 30 years, 409 males), taking vacations in beach resorts in Chile. Results: The hours of higher sun exposure ranged from 12 AM to 4 PM. Thirty seven percent of subjects were exposed more than 2 hours during this high risk lapse. Women and subjects aged less than 25 years were those with the riskiest behaviors. Fifty four percent used some type of photoprotection and 50% used ocular protection. Seventy percent used creams with sun screen and 74% used a sun protection factor higher than 15. Seventy percent applied the sun screen as recommended. Thirty eight percent had at least one sun burn in the last two years. More than 90% of subjects were aware of the relationship between sun exposure and skin cancer but 60% did not know the hours of higher ultraviolet radiation. The information about sun exposure was obtained from television in 57% of surveyed individuals. Conclusions: More educational campaigns about the risk of sun exposure are needed to reduce risky behaviors in the Chilean population.

RESUMO

La queratosis liquenoide no es bien conocida, a pesar de habérsela descripto en 1966. Se hace una revisión de la literatura y se presentan tres casos propios. Los tres pacientes eran de sexo femenino, de 38, 52 y 68 años. En los tres casos se trató de lesiones únicas, dos aparecieron en zonas expuestas al sol y otras dos tenían forma anular simulando un basalioma. Sólo una era rosada como clásicamente se la describe. La queratosis liquenoide sería una variedad de liquen rojo actínico
