RESUMEN

INTRODUCCIÓN: La teledermatología (TD) es la especialidad clínica más desarrollada de la telemedicina. El desarrollo de la TD en un país completo no se ha estudiado previamente en profundidad. MÉTODOS: El objetivo fue analizar los modelos de TD en práctica real en España, centrándose en la organización, los aspectos técnicos, la docencia y las ventajas/desventajas percibidas por los teledermatólogos. Se realizaron 2 encuestas con teledermatólogos en 2009 y 2014. RESULTADOS: Se identificaron 25 centros utilizando TD en 2009 y 70 en 2014. La encuesta ampliada fue completada por 21 centros en 2009 y 42 en 2014. Las características generales en 2014 fueron: TD almacenamiento (TDA) fue la técnica predominante (83%), solo el 12% TD en tiempo real y el 5% TD híbrida. El 75% de los pacientes vistos en TD viven a menos de 25 km (TD urbana). La mayoría de los centros utilizan cámaras bridge de gama media y solo el 12% utiliza los teléfonos móviles. El 15% practica teledermoscopia y el 15% TD terciaria. En el 25%, la TD se restringió a la oncología cutánea; el 66% utiliza la TD para formación de médicos de primaria. Las ventajas principales (puntuación 0-10) fueron priorización en oncología (8,3), asistencia rápida de urgencias (7,8), la formación y la comunicación con los médicos de primaria (7,6), el cribado de enfermedad banal (7,6) y la disminución de las visitas presenciales (7,6). Los principales inconvenientes fueron (puntuación 0-10): la baja calidad de imágenes (6,3), el miedo al error (5,7), difícil coordinación con los médicos de primaria (MP) (3,8) y consumo de tiempo (3,3). La evolución 2009-2014 mostró más centros con TD y más teledermatólogos, mejor tecnología y aumento de los modelos TDA y urbano. CONCLUSIÓN: La TD es una tecnología emergente que comienza su fase de consolidación en España. Más del 25% de los centros de dermatología en España han puesto en práctica un sistema de TD. El modelo predominante es TDA en un entorno urbano. Los dermatólogos perciben la TD como una opción efectiva con más ventajas que desventajas. La satisfacción general es alta, sin embargo, todavía hay áreas que necesitan mejoras significativas

INTRODUCTION: Teledermatology is the most advanced clinical specialty in telemedicine. The development of teledermatology in specific countries has not been studied in depth. METHODS: Our objective was to analyze teledermatology models in clinical practice in Spain. We paid special attention to organization, technical aspects, training, and the advantages/disadvantages as seen by teledermatologists. Two surveys were carried out (2009 and 2014). RESULTS: Teledermatology was used at 25 centers in 2009 and at 70 in 2014. The extended survey was completed by 21 centers in 2009 and 41 in 2014. Store-and-forward teledermatology was the main technique (83%) in 2014. Only 12% of centers used the real-time method, and 5% used a hybrid modality. Patients lived less than 25 km away in 75% of cases (urban teledermatology). Most centers used mid-range bridge cameras; only 12% used mobile phones. Teledermoscopy and tertiary teledermatology were each used in 15% of centers. Teledermatology was restricted to skin cancer in 25% of cases, and 66% of centers used it to train primary care physicians. The main advantages, assessed on a scale of 1 to 10, were prioritization in cancer screening (8.3), rapid emergency care (7.8), training of and communication with primary care physicians (7.6), screening for trivial conditions (7.6), and reduction in the number of face-to-face visits (7.6). The main disadvantages were poor image quality (6.3), fear of error (5.7), difficulty in coordinating with primary care physicians (3.8), and time commitment (3.3). Between 2009 and 2014, the number of centers using teledermatology and the number of teledermatologists increased, as did use of the store-and-forward and urban models. The technology used also improved. CONCLUSION: Teledermatology is an emerging technology that is becoming well established in Spain. More than 25% of dermatology centers in Spain have implemented a teledermatology model. Store-and-forward in an urban setting is the most widely used modality. Teledermatologists see this technology as an effective option with more advantages than disadvantages. General satisfaction is high, although there is room for significant improvement in some areas

RESUMEN

BACKGROUND: Port wine stains (PWSs) are commonly treated by the pulsed dye laser. However, treatment of hypertrophic or resistant PWSs is a major therapeutic challenge. The long-pulsed Alexandrite laser could be a safe and effective treatment for resistant PWSs, due to an increase depth of penetration of 50-75% over PDL. OBJECTIVE: The aim of this study was to assess the efficacy and safety of a long-pulsed Alexandrite laser in patients with hypertrophic, dark and/or resistant PWSs. Pink pale resistant PWS were excluded from the study. METHODS: Twenty-one patients (age 20-75 years), phototypes I-IV on the Fitzpatrick scale, with PDL dark resistant PWSs were treated with long-pulsed Alexandrite laser. We excluded high phototypes and PDL pink resistant PWSs. All patients were treated with 3 laser sessions at settings of 3-ms pulse duration, 10-mm spot, 35-55J/cm2, with cooling (Dynamic Cooling Device 50 ms with delay 30 ms). Laser sessions were repeated approximately every 2 months. Three dermatologists evaluated treatment effectiveness by means of photographs of the patients before and after laser treatment (scale from 0 to 4). Adverse events were registered. Patient satisfaction was also assessed (scale from 0 to 10). RESULTS: Mean global improvement was rated as 2.28. Long-lasting side effects included minimal scarring after blistering in 1 patient. Mean patient satisfaction was 8.5. CONCLUSIONS: Our study concludes that long-pulsed Alexandrite laser was effective for treatment of resistant PWSs, although the therapeutical window is narrow with this treatment

ANTECEDENTES: Las manchas en vino de oporto (MVO) son normalmente tratadas con láser de colorante pulsado. Sin embargo, el tratamiento de MVO hipertróficas o resistentes continúa siendo un importante reto terapéutico. El láser de Alejandrita de pulso largo podría ser un método seguro y eficaz para el tratamiento de estas lesiones, debido a que la profundidad que alcanza puede superar entre un 50-75% al láser de colorante pulsado. OBJETIVO: El objetivo de este estudio fue evaluar la eficacia y la seguridad del láser de Alejandrita de pulso largo en pacientes con MVO hipertróficas y/o resistentes. Los pacientes con MVO resistentes de color rosa pálido fueron excluidos del estudio. MÉTODOS: Veintiún pacientes (Edades entre 20-75 años), fototipos I-IV en la escala Fitzpatrick, con MVO oscuras, resistentes al tratamiento con láser de colorante pulsado fueron tratados con láser de Alejandrita de pulso largo. Se excluyeron los fototipos altos y las MVO de color rosado pálido. Todos los pacientes fueron tratados con 3 sesiones de láser con los siguientes parámetros: duración de pulso de 3 ms, spot de 10 mm de diámetro, fluencias comprendidas entre 35 y 55 J/cm2, con refrigeración (Dynamic Coolong Device). El intervalo de tiempo entre sesiones fue de 2 meses aproximadamente. Tres dermatólogos evaluaron la efectividad del tratamiento a través de las fotografías de los pacientes antes y después del tratamiento con láser (escala de 0 a 4). Se registraron los eventos adversos acontecidos. La satisfacción del paciente también se evaluó (escala de 0 a 10). RESULTADOS: La mejoría global media fue de 2,28. Los efectos adversos duraderos fueron lesiones cicatriciales mínimas en un paciente. La satisfacción media de los pacientes fue de 8,5. CONCLUSIONES: Nuestro estudio concluye que el láser de Alejandrita de pulso largo puede ser eficaz en el tratamiento de MVO resistentes, aunque la ventana terapéutica es estrecha con este tratamiento
