Estudio observacional de seguridad, prospectivo y unicéntrico para determinar la capacidad alergogénica de Mercromina Film(R) y otros antisépticos de uso común en pacientes con dermatitis de contacto / Prospective Single-Center Observational Study of the Allergenic Potential of Mercromina Film and Other Common Antiseptics in Patients With Contact Dermatitis

INTRODUCCIÓN: Pese al uso tan extendido de la Mercromina Film® y otros antisépticos de uso tópico, estos no se encuentran incluidos en la serie estándar española del Grupo Español de Investigación en Dermatitis de Contacto y Alergia Cutánea, realizada ante sospecha de dermatitis alérgica de contacto. Además, no existen estudios recientes sobre capacidad alergogénica de la merbromina, motivo por el que se plantea la presente investigación. OBJETIVO: Determinar la capacidad alergénica de la merbromina y compararla con la de los otros antisépticos de uso tópico frecuentemente utilizados en la práctica clínica, entre los que se incluye la povidona iodada, clorhexidina y eosina. MATERIAL Y MÉTODOS: Estudio observacional de seguridad, prospectivo y unicéntrico realizado en 105 pacientes con sospecha de dermatitis alérgica de contacto que acudieron a la consulta del departamento de dermatología. RESULTADOS: El 1,9% de los participantes presentó dermatitis alérgica de contacto a la merbromina. El 12,4% de los pacientes presentó sensibilización ante la povidona iodada. Las diferencias entre el porcentaje de pacientes que presentó dermatitis alérgica de contacto a Betadine (R) solución dérmica respecto al resto de antisépticos fueron estadísticamente significativas (prueba de McNemar; p < 0,05). No se registraron efectos adversos con ninguno de los antisépticos en estudio. CONCLUSIONES: Mercromina Film ha demostrado una muy baja capacidad alergénica en la prueba de patch test. Cuando se comparan con otros antisépticos tópicos, la mayor capacidad alergénica se encontró con la povidona iodada

INTRODUCTION: Although Mercromina Film and other topical antiseptics are widely used, they are not included in the standard series recommended by the Spanish Contact Dermatitis and Skin Allergy Research Group for testing suspected allergic contact dermatitis (ACD). Furthermore, no recent studies have investigated the allergenic potential of merbromin. OBJECTIVE: To determine the allergenic potential of merbromin and compare it with that of other topical antiseptics widely used in clinical practice, including povidone-iodine, chlorhexidine, and eosin. MATERIAL AND METHODS: Prospective single-center observational safety study of 105 patients with suspected ACD seen at the dermatology department of our hospital. RESULTS: Of the 105 patients studied, 1.9% had a positive patch test to merbromin and 12.4% were sensitized to povidone-iodine. The differences in the proportion of patients with ACD to Betadine Solución Dérmica (povidone-iodine) compared with the rest of the antiseptics was statistically significant (McNemar test, P < .05). No adverse reactions were observed in any of the patients. CONCLUSIONS: Based on the patch tests conducted, Mercromina Film has very low allergenic potential. The highest allergenic potential was observed for povidone-iodine

The highest allergenic potential was observed for povidone-iodine.

Infecciones de transmisión sexual: experiencia de una consulta multidisciplinar en un hospital terciario (2010-2013) / Sexually Transmitted Infections: Experience in a Multidisciplinary Clinic in a Tertiary Hospital (2010-2013)

INTRODUCCIÓN: Las infecciones de transmisión sexual son un motivo de consulta creciente en nuestro medio. El objetivo de este trabajo es describir y analizar las características epidemiológicas, conductuales, clínicas y microbiológicas de los pacientes registrados en una unidad de infecciones de transmisión sexual de un hospital terciario. MÉTODOS: Estudio descriptivo, retrospectivo y unicéntrico realizado en una unidad multidisciplinar especializada en infecciones de transmisión sexual de un hospital terciario entre 2010 y 2013. Se recogieron datos epidemiológicos, clínicos y conductuales mediante entrevista oral abierta y cuestionario estandarizado, y se llevó a cabo la obtención de muestras para estudio microbiológico. RESULTADOS: Se estudiaron 546 pacientes, de los cuales fueron 96% varones, 41% infectados por el VIH, 56% hombres que tienen sexo con hombres. Los motivos de consulta más prevalentes fueron: uretritis, úlceras genitales y/o anales/perianales, proctitis, úlceras orales, contacto sexual de persona con ITS conocida y contacto sexual de riesgo. Los diagnósticos microbiológicos más frecuentes fueron: Neisseria gonorrhoeae en uretritis, Treponema pallidum en úlceras genitales y/o anales/perianales y Chlamydia trachomatis serovares de linfogranuloma venéreo en proctitis. Las principales ITS estudiadas fueron más prevalentes en varones homosexuales e infectados por el VIH. CONCLUSIÓN: Se confirma el incremento en la incidencia de las infecciones de transmisión sexual en los últimos años y las características epidemiológicas de la epidemia VIH/ITS de nuestro entorno

INTRODUCTION: The number of consultations for sexually transmitted infections (STIs) is increasing in Spain. The aim of this study was to describe and analyze the epidemiological, behavioral, clinical, and microbiological characteristics of patients registered at the STI unit of a tertiary hospital. METHODS: This was a retrospective, single-center descriptive study carried out between 2010 and 2013 in a multidisciplinary unit specialized in STIs, situated in a tertiary hospital. Epidemiological, clinical, and behavioral data were gathered using a face-to-face interview and a standardized questionnaire. Samples were collected for microbiology analysis. RESULTS: The study included 546 patients: 96% were men, 41% had human immunodeficiency virus (HIV) infection, and 56% were men who have sex with men. The reasons for consultation were the following: urethritis; genital, anal, or perianal ulcers; proctitis; oral ulcers; sexual contact with a person with a known STI; and high-risk sexual contact. The most common microbiological diagnoses were Neisseria gonorrhoeae in urethritis, Treponema pallidum in genital and anal or perianal ulcers, and Chlamydia trachomatis lymphogranuloma venereum serovars in proctitis. The highest prevalences of the main STIs studied occurred in homosexual men with HIV infection. CONCLUSION: This study confirms the increase in the incidence of STIs in recent years and the epidemiological characteristics of the HIV/STI epidemic in Spain
