ABSTRACT
BACKGROUND: Topical imiquimod has shown to be an effective treatment for EMPD, although available evidence supporting its use is based on case reports and small series of patients. OBJECTIVES: To investigate the therapeutic outcomes and analyze potential clinico-pathological factors associated with imiquimod response in a large cohort of EMPD patients. METHODS: Retrospective chart review of 125 EMPD patients treated with imiquimod at 20 Spanish tertiary-care hospitals. RESULTS: During the study period, patients received 134 treatment regimens with imiquimod, with 70 (52.2%) cases achieving complete response (CR), 41 (30.6%) partial response and 23 (17.2%) no response. The cumulative CR rates at 24 and 48 weeks of treatment were 46.3% and 71.8%, respectively, without significant differences between first-time and previously treated EMPD. Larger lesions (≥6â cm; p = 0.038) and EMPD affecting >1 anatomical site (p = 0.002) were significantly associated with a worse treatment response. However, the CR rate did not differ significantly by the number of treatment applications (≤4 vs. > 4 times/week; p = 0.112). Among patients who achieved CR, 30 (42.9%) developed local recurrences during a mean follow-up period of 36â months, with an estimated 3 and 5-year recurrence free-survival of 55.7% and 36.4%, respectively. CONCLUSIONS: Imiquimod appears as an effective therapeutic alternative for both first-line and previously treated EMPD lesions. However, a less favorable therapeutic response could be expected in larger lesions and those affecting >1 anatomical site. Based on our results, a 3-4 times weekly regimen of imiquimod with a treatment duration of at least 6â months could be considered an appropriate therapeutic strategy for EMPD patients.
ABSTRACT
BACKGROUND: Evidence regarding long-term therapeutic outcomes and disease-specific survival (DSS) in Extramammary Paget's disease (EMPD) is limited. OBJECTIVES: To assess the DSS and outcomes of surgical and nonsurgical therapeutic modalities in a large cohort of EMPD patients. METHODS: Retrospective chart review of EMPD patients from 20 Spanish tertiary care hospitals. RESULTS: Data on 249 patients with a median follow-up of 60 months were analyzed. The estimated 5-, 10-, and 15-year DSS was 95.9%, 92.9%, and 88.5%, respectively. A significantly lower DSS was observed in patients showing deep dermal invasion (≥1 mm) or metastatic disease (P < .05). A ≥50% reduction in EMPD lesion size was achieved in 100% and 75.3% of patients treated with surgery and topical therapies, respectively. Tumor-free resection margins were obtained in 42.4% of the patients after wide local excision (WLE). The 5-year recurrence-free survival after Mohs micrographic surgery (MMS), WLE with tumor-free margins, WLE with positive margins, radiotherapy, and topical treatments was 63.0%, 51.4%, 20.4%, 30.1%, and 20.8%, respectively. LIMITATIONS: Retrospective design. CONCLUSIONS: EMPD is usually a chronic condition with favorable prognosis. MMS represents the therapeutic alternative with the greatest efficacy for the disease. Recurrence rates in patients with positive margins after WLE are similar to the ones observed in patients treated with topical agents.

El Kathon es un conservante resultante de la mezcla de dos isotiazolinonas. Se utiliza preferentemente en la industria cosmética a concentraciones 3-15 ppm. También se ha impuesto su presencia en productos de limpieza de uso doméstico y actualmente a concentraciones más altas en preparados de uso industrial como aceites de corte, emulsiones de látex, pinturas al temple, reveladores de fotografía y radiografía, aceites para motores Diesel. Todo ello hace que sea un sensibilizante importante en nuestra vida privada y profesional. Objetivos: 1. Demostrar la relación del Kathon como sustancia sensibilizante en el desarrollo de dermatitis de contacto. 2. Demostrar la relación entre Kathon y dermatitis de contacto de origen laboral y determinadas profesiones. Metodología: Estudio descriptivo: revisión de las historias clínicas de los pacientes que fueron vistos por el Servicio de Dermatología Laboral del Instituto Nacional de Medicina y Seguridad en el Trabajo durante los años 2004-2006; 2333 pacientes, remitidos por diferentes lesiones dermatológicas con posible relación laboral. Buscaremos los sensibilizados a Kathon y analizaremos las variables: sexo, edad, profesión, enfermedades dermatológica de base, localización de las lesiones, manejo de productos que contengan Kathon. Realizaremos el análisis estadístico con el programa SPSS. Resultados: De las 110 positividades a Kathon, 32 son relacionadas con el trabajo (37,2%). Podemos sumarles otros 13 casos dudosos (15,11%) y de estos casos positivos, el 46,6% fueron varones. Conclusiones: El Kathon es un conservante muy utilizado en el mundo laboral, y son precisamente las profesiones que más productos con Kathon usan, las que mayor número de casos registran
The Kathon is a preservative obtained of the mixture of two isothiazolinones. It is preferently used in the cosmetic industry at 3-15 ppm concentrations. Its presence has increased from the end of the 70's in Europe and from the middle of the 80's in USA. The product presence has also imposed in house-cleaning use and at higher concentrations in the industrial use as motor oils, latex emulsions, painting oils, revealers for photography and x-ray, oils for diesel engines. All of these make it to be an important irritating product in our private and professional life. Objectives: 1. To demonstrate the relation of the Kathon like irritating substance in producing contact dermatitis. 2. To demonstrate to the relation between Kathon and contact dermatitis of labor origin and certain professions. Methodology: Descriptive study: revision of clinical histories of the patients who have been observed in the Department of Labor Dermatology of the National Institute of Medicine and Labor Security during years 2004-2006; 2333 patients, found with different dermatological injuries with possible labor relation. We will look for the Kathon-sensitive persons and we will analyze the variables: sex, age, dermatological profession, dermatological diseases, location of the injuries, product handling that contains Kathon. We will make the statistical analysis with program SPSS. Results: Of the 110 positive reactions to Kathon, 32 are related to the labour activities (29.09%). We can add other 13 doubtful cases to them (11.81%) and of these positive cases, 46.6% were men. Conclusions: The Kathon is an additive very used in the labour ambit. The professions that are using more products with Kathon are those with greater number of cases registered

El progresivo envejecimiento de la población está provocando el desarrollo como grupo profesional de los cuidadores profesionales de ancianos, los auxiliares de geriatría. Puede considerarse un grupo de riesgo para el desarrollo de dermatosis ocupacional debido a las características del trabajo que desempeñan, con una regular exposición a irritantes cutáneos y a trabajo húmedo. Los estudios centrados en la patología cutánea de este colectivo son escasos. Objetivo: El objetivo de este estudio es describir y analizar las características y los diagnósticos clínicos dermatológicos de los pacientes que trabajan como cuidadores de ancianos valorados en nuestro servicio. Material y métodos: Se ha llevado a cabo un estudio observacional retrospectivo de los datos de 41 pacientes cuidadores de ancianos estudiados en nuestro servicio durante un periodo de 11 años. Resultados: Encontramos un predominio total de mujeres. El lugar de afectación más frecuente fueron las manos. Los diagnósticos más frecuentemente establecidos fueron: Eczema endógeno (39,6%), dermatitis de contacto irritativa (DCI) (27,1%), dermatitis de contacto alérgica (DCA) (12,5%), Sin lesiones (10,4%), urticaria de contacto al látex (4,2%) y otros. Conclusiones: El colectivo de cuidadores de ancianos es un grupo en aumento y de gran importancia social. Al desempeñar una labor que implica un trabajo húmedo se debe considerar un grupo de riesgo para el desarrollo de dermatosis profesionales. En nuestro estudio destaca que el diagnóstico de eczema endógeno, representado por la dermatitis atópica, sea el más frecuente, explicándose esto porque una irritación provocada por un trabajo húmedo y la oclusión pueden desencadenar un eczema en el individuo con un fondo atópico, que en otras condiciones se habría mantenido latente. Son necesarios futuros estudios más extensos en este sector profesional
The increasing proportion of elderly citizens worldwide is leading to the development of a new professional group of people who are specialized in elderly personal care. They may have an increased risk of occupational skin damage due to the characteristics of their work that is often associated with regular exposure to skin irritants and constant wetwork. Skin disease studies within this group are rare. Aims: The aim of this study was to describe and analyse the characteristics and dermatologic diagnosis of the patients that work taking care of elderly people studied in our department. Methods: We studied retrospectively all 41 patients who work as elder care-taker who attended our department in a 11-year period. Results: We found an absolute female predominance. The most common location affected was the hands. Of the skin diseases clinically diagnosed, endogenous eczema showed the highest prevalence (39,6%) followed by irritant contact dermatitis (ICD) (27,1%), allergic contact dermatitis (ACD) (12,5%), asymptomatic (10,4%), allergy to natural rubber latex (NRL) (4,2%) and others. Conclusions: Elderly care-taker workers are emerging and they have a great social importance. They are at increased risk of occupational skin disease due to contact with several substances and wet work. In our study, endogenous eczema, represented by atopic dermatitis, is the most important diagnosis. It could be concluded that irritants, occlusion and wet work favoured the development of dermatitis in vulnerable patients that would be remained asymptomatic avoiding this work. New further studies are needed

La Dermatosis Neutrofílica del dorso de la mano (DNDM) es una entidad descrita recientemente. Se presenta con placas eritematosas, pústulas y ampollas limitadas al dorso de las manos, y la anatomía patológica se caracteriza por un denso infiltrado de neutrófilos. Desde hace unos años existe un debate para clasificar esta patología dentro de las dermatosis neutrófilicas o de las vasculitis pustulosas. Presentamos un nuevo caso de DNDM en la que no se objetiva vasculitis en la anatomía patológica
Neutrophilic dermatosis of the dorsal hands (NDDH) is a recently described disorder. This condition presented with erythematous plaques, pustules and bullae limited to the dorsal hands, and it is characterized histologically by a dense neutrophilic infiltrate. Controversy remains to categorize this entity as a neutrophilic dermatosis or a pustular vasculitis. We described a new case of NDDH that lack vasculitis in the biopsy findings
