Resumen Introduccion Existen escasos estudios de larga duracion sobre las enfermedades atendidas en las consultas de Dermatologia. El objetivo de este estudio es analizar los motivos de derivacion y los diagnosticos realizados en el Servicio de Dermatologia del Complejo Hospitalario de Navarra (CHN) durante el ano 2018. Metodologia Se han analizado de manera retrospectiva las primeras visitas realizadas en nuestras consultas durante el ano 2018 evaluando los siguientes parametros: el sexo, la edad, el origen del paciente, el codigo de derivacion primaria (Clasificacion Internacional de Atencion Primaria – CIAP) y el codigo diagnostico del Servicio de Dermatologia (Clasificacion Internacional de Enfermedades – CIE 9). Resultados La tasa de tderivacion a nuestro servicio en 2018 fue de 45,5 consultas presenciales/1.000 habitantes, con una ratio presencial/no presencial 12:1. Los diagnosticos CIE mas frecuentemente realizados en la consulta presencial son nevus melanociticos (15%), queratosis seborreica (12%) y queratosis actinica (9%). Un 47% de los diagnosticos CIE realizados en la consulta presencial corresponden a enfermedad tumoral benigna y maligna. Conclusiones A pesar de sus limitaciones, la codificacion resulta imprescindible para conocer a la poblacion atendida, sus necesidades reales y poder optimizar el reparto de recursos. Creemos que es importante invertir en el diagnostico clinico y dermatoscopico de las lesiones pigmentadas, para de esta manera poder mejorar la derivacion. Con la informacion actual de la que disponemos no se puede plantear un cribado o priorizacion de la derivacion con base en el analisis del codigo CIAP.

As research continues, new drugs will no doubt be added to the current pool of treatments for moderate-to-severe atopic dermatitis (AD). This raises the need for studies to determine prescriber preferences for different pharmacological options and the factors that influence their choice of treatment. Here we aim to explore physician preferences in the systemic treatment of moderate-to-severe AD, identify the sociodemographic characteristics that can influence physician preferences, and evaluate their satisfaction with current AD therapies.A discrete-choice experiment (DCE) survey was administered to physicians treating patients with AD in Spain. Results were analyzed using a conditional logit model to estimate the relative importance of each attribute and the maximum risk accepted to achieve therapeutic benefit.A total of 28 respondents completed the DCE survey (67.9% female, mean age 45.9 years). Participants identified objective clinical efficacy and risk of severe adverse events (AEs) as the most important attributes, followed by improvement in sleep and pruritus and faster onset of action from the start of the treatment. Respondents gave less importance to mode of administration and therapeutic benefit in other atopic conditions. Respondents were willing to accept an increased risk of severe AEs and mild-to-moderate AEs leading to treatment discontinuation due to intolerance in order to obtain improvements in efficacy, sleep, and pruritus, and long-term clinical benefit.Our findings can help prescribers choose the most appropriate systemic AD therapy.

Porokeratotic eccrine and hair follicle nevus is a very rare non-hereditary disorder of keratinization with eccrine and hair follicle involvement with only 9 cases described in the literature. In 2009 the term porokeratotic anexial ostial nevus was proposed to comprehend porokeratotic eccrine and hair follicle nevus and a related and more common process without follicular involvement: porokeratotic eccrine ostial and dermal duct nevus Recent findings suggest that both entities may be produced by a mutation in GJB2 gene, which is associated to KID syndrome. Herein we report 2 cases of porokeratotic eccrine and hair follicle nevus and review the existing cases in the Spanish and English literature.

Perianal complaints are often consulted in dermatology clinics, and in many cases, a conclusive diagnosis is not easily made.The aim of this study was to study and identify the epidemiological, clinical, and contact allergy features of patients with perianal dermatitis who attended at a contact dermatitis unit in a tertiary hospital in Spain.Adult patients with long-lasting (4 weeks) perianal dermatitis were recruited during the past 10 years for investigation and follow-up. Every patient underwent a diagnostic workup consisting of dermatological exploration and patch tests with the standard and specific series, as well as the patients' own products. General surgical exploration was also performed in some patients.One hundred twenty-four patients were included. The MOAHLFA index was as follows: 43.5, 0, 4.8, 11.3, 1.6, 8.1, and 75. The main final diagnoses were allergic contact dermatitis (32.3%), psoriasis (24.2%), irritant contact dermatitis (17.7%), and lichen simplex (neurodermatitis) (10%). Eighty-one patients (66.1%) showed 1 or more positive reactions, and in 52 patients (43%), positive reactions relevant to the present disease were found.Contact allergy in patients with long-lasting perianal complaints is frequent. It is mandatory for these patients to be referred to a dermatologist for an adequate evaluation and patch testing. Methylchloroisothiazolinone/methylisothiazolinone seems as the most common allergen implicated in perianal contact dermatitis.
