Introduction and objectives Optimal medical therapy decreases mortality and heart failure (HF) hospitalizations in HF patients with reduced left ventricular ejection fraction. Women have been underrepresented in clinical trials and not specifically evaluated. This study aimed to compare the safety and effectiveness of drug titration in women vs men. Methods This post hoc gender study of the ETIFIC multicenter randomized trial included hospitalized patients with new-onset HF with reduced ejection fraction and New York Heart Association II-III and no contraindications to beta-blockers. A structured 4-month titration process was implemented in HF clinics. The primary endpoint was the mean relative dose (% of target dose) of beta-blockers achieved by women vs men. Secondary endpoints included the mean relative doses of angiotensin-converting enzyme inhibitors, angiotensin II receptor blockers, and mineralocorticoid receptor antagonists, adverse events, and other clinical outcomes at 6 months. Results A total of 320 patients were included, 83 (25.93%) women and 237 (74.06%) men (76 vs 213 analyzed). The mean±standard deviation of the relative doses achieved by women vs men were as follows: beta-blockers 62.08%±30.72% vs 64.4%±32.77%, with a difference of−2.32% (95%CI,−10.58-5.94), P = .580; and mineralocorticoid receptor antagonists 79.85%±27.72% vs 67.29%±31.43%, P =.003. No other differences in drug dosage were found. Multivariate analysis showed nonsignificant differences. CV mortality was 1 (1.20%) vs 3 (1.26%), P=1, and HF hospitalizations 0 (0.00%) vs 10 (4.22%), P=.125. Conclusions In a post hoc analysis from the HF-titration ETIFIC trial, we found nonsignificant gender differences in drug dosage, cardiovascular mortality, and HF hospitalizations (AU)

Introducción: Los estudios epidemiológicos sobre incidencia de dermatitis alérgica de contacto en población pediátrica son escasos. Algunos trabajos consideran que se trata de una entidad infradiagnosticada, y que en muchos casos no se sospecha clínicamente, no realizándose pruebas epicutáneas. No obstante se han comunicado tasas prevalencia de hasta el 20% de sensibilización a alérgenos en la población pediátrica, por lo que probablemente debería ser tenida en cuenta como una posibilidad diagnóstica en este grupo de edad. Material y método: Se ha realizado un análisis retrospectivo de la base de datos de alergia cutánea del servicio de Dermatología del Hospital General seleccionando los casos diagnosticados en niños de entre 0 y 16 años durante los últimos 15 años (año 2000 hasta 2015). El estudio incluye variables epidemiológicas (edad, sexo, antecedentes de atopia) y clínicas (localización de las lesiones, baterías de alérgenos empleadas, alérgenos positivos y su relevancia). Resultados: De los 4.593 pacientes estudiados con pruebas epicutáneas en los últimos 15 años, 265 (6%) correspondían a niños de 0-16 años. Ciento cuarenta y cuatro pacientes (54,3%) mostraron positividad para al menos uno de los alérgenos parcheados. Los alérgenos más frecuentemente identificados fueron en orden decreciente: tiomersal, cloruro de cobalto, colofonia, parafenilendiamina, dicromato potásico, mercurio y níquel. La sensibilización fue considerada de relevancia presente en 177 casos (61,3%). Conclusión: Más de la mitad de los niños estudiados mostraron sensibilización a uno o más alérgenos, con un porcentaje importante de sensibilizaciones relevantes. Todo niño con sospecha clínica de dermatitis alérgica de contacto debería ser remitido para realización de pruebas epicutáneas. Al no existir pruebas estandarizadas en este colectivo se requiere un alto nivel de sospecha clínica y un conocimiento de los alérgenos más frecuentemente implicados de cara a seleccionar los alérgenos a parchar (AU)
Background: Few epidemiological studies have investigated the incidence of allergic contact dermatitis in children. Underdiagnosis has been observed in some studies, with many cases in which the condition is not suspected clinically and patch tests are not performed. However, the prevalence of pediatric sensitization to allergens has been reported to be as high as 20%, and the diagnosis should therefore be contemplated as a possibility in this age group. Material and methods: We performed a retrospective analysis of the skin allergy database of the Dermatology Department of Consorcio Hospital General Universitario de Valencia. Children between 0 and 16 years of age diagnosed with allergic contact dermatitis in the previous 15 years (between 2000 and 2015) were included in the analysis. Epidemiological (age, sex, history of atopy) and clinical (site of the lesions, allergen series applied, positive reactions, and their relevance) variables were gathered. Results: Patch tests had been performed on 4,593 patients during the study period. Of these, 265 (6%) were children aged between 0 and 16 years. A positive reaction to at least one of the allergens tested was observed in 144 (54.3%) patients in that group. The allergens most frequently identified were the following (in decreasing order of frequency): thiomersal, cobalt chloride, colophony, paraphenylenediamine, potassium dichromate, mercury, and nickel. The sensitization was considered relevant in 177 (61.3%) cases. Conclusions: More than half of the children studied showed sensitization to 1 or more allergens, with a high percentage of relevant sensitizations. All children with a clinical suspicion of allergic contact dermatitis should be referred for patch testing. As no standardized test series have been developed for this age group, a high level of clinical suspicion and knowledge of the allergens most commonly involved are required when selecting the allergens to be tested (AU)

La dermatitis alérgica de contacto (DAC) a cosméticos es una dolencia con una incidencia creciente en la población, paralelamente a la generalización del uso de cosméticos en la sociedad, así como a su proliferación y diversificación. El objetivo del estudio es determinar la prevalencia de DAC a cosméticos en nuestro medio, analizar su evolución temporal y sus características clínico-epidemiológicas, así como definir los alérgenos y los cosméticos implicados. Se ha realizado un estudio prospectivo durante los años 2005-2013 en la Unidad de Alergia Cutánea del Hospital General Universitario de Valencia, y se ha comparado de forma retrospectiva con el periodo previo de 1996-2004. Se ha incluido a 5.419 pacientes estudiados con pruebas epicutáneas durante el periodo total del estudio. La prevalencia media de DAC a cosméticos ha aumentado de 9,8% en el periodo 1996-2004 a 13,9% en el periodo 2005-2013. La DAC a cosméticos se ha correlacionado con el sexo femenino, pero no con la atopia. El kathon CG (mezcla de metilcloroisotiazolinona y metilisotiazolinona), las fragancias y la parafenilendiamina (PPDA) se han mantenido como las causas más frecuentes, aunque en los últimos años los acrilatos y los filtros solares han sido alérgenos emergentes
The incidence of allergic contact dermatitis (ACD) to cosmetics in the general population is rising with the increasing use of cosmetic products and their proliferation and diversification. The aims of this study were to determine the prevalence of ACD to cosmetics in our setting, analyze changes over time, describe the clinical and epidemiological features of this allergic reaction, and identify the allergens and cosmetics involved. We performed a prospective study at the skin allergy unit in Hospital General Universitario de Valencia in Spain between 2005 and 2013 and compared our findings with data collected retrospectively for the period 1996 to 2004. The 5419 patients who underwent patch testing during these 2 periods were included in the study. The mean prevalence of ACD to cosmetics increased from 9.8% in the first period (1996-2004) to 13.9% in the second period (2005-2013). A significant correlation was found between ACD to cosmetics and female sex but not atopy. Kathon CG (blend of methylchloroisothiazolinone and methylisothiazolinone), fragrances, and paraphenylenediamine were the most common causes of ACD to cosmetics during both study periods, and acrylates and sunscreens were identified as emerging allergens during the second period

OBJETIVO: El objetivo de este trabajo es el estudio descriptivo de los pacientes con dermatitis alérgica de contacto por níquel que han sido atendidos en un hospital de referencia en dermatología en un periodo de 10 años. MATERIAL Y MÉTODOS: Se han analizado los datos de todos los pacientes parchados con la batería estándar del Grupo Español de Investigación en Dermatitis de Contacto y Alérgica Cutánea (GEIDAC) que incluye un parche con sulfato de níquel en vaselina al 5%, a partir de la base de datos informatizada de la sección de alergia cutánea de nuestro servicio. Para conocer la implicación de diferentes objetos metálicos en el origen de la dermatitis utilizamos un método colorimétrico llamado test de dimetilglioxima (DMGO). RESULTADOS: Durante el periodo de estudio se ha explorado mediante pruebas epicutáneas con la batería estándar del GEIDAC a 3.404 pacientes. Del total de pacientes parchados un 24,2% presentaron un parche positivo para sulfato de níquel al 5% en vaselina. Sin embargo, de los 824 pacientes sensibilizados al níquel solo en 57 de ellos (6,9%) se pudo demostrar una asociación de la sensibilización con la dermatitis por la que consultaban. CONCLUSIONES: Solo se identificó relevancia presente en un pequeño porcentaje de pacientes con positividad al níquel en las pruebas epicutáneas. Destacamos la utilidad del test de DMGO como método de ayuda para establecer la relevancia de la positividad del parche con níquel, e incluso para conocer el objeto causante de dicha dermatitis
OBJECTIVE: The aim of this study based on the records of the dermatology department of a tertiary referral hospital was to describe patients treated for allergic contact dermatitis induced by nickel between 2000 and 2010. MATERIALS AND METHODS: From records of the skin allergy section of the dermatology department we extracted and analyzed information for patients who underwent patch testing with the standard series of the Spanish Contact Dermatitis Research Group (GEIDAC), which includes a patch with 5% nickel sulfate in petroleum jelly. The possibility that nickel release from various objects might have triggered the patient's dermatitis was assessed with the dimethylglyoxime spot test, which reveals a reddish precipitate if the metal is present. RESULTS: A total of 3,404 patients underwent GEIDAC patch testing during the study period; 24.2% had positive reactions to the patch containing 5% nickel sulfate in petroleum jelly. However, the contact dermatitis could be attributed to nickel in only 57 of the 824 patients (6.9%) who showed sensitization to nickel. CONCLUSIONS: Patch-test evidence of sensitization was found to be clinically relevant in only a small percentage of patients. We emphasize the usefulness of the dimethylglyoxime test to help establish the relevance of a positive nickel patch test. This test is even useful for identifying the specific object responsible for a patient's dermatitis

Presentamos 7 casos de dermatitis de contacto por povidona yodada (PVP-I) en pacientes sometidos a cirugía. El diagnóstico se basó en la clínica, la historia de exposición, la localización de las lesiones y el resultado de las pruebas epicutáneas. La dermatitis puede aparecer en el área quirúrgica, pero también en zonas distantes, aunque expuestas a la PVP-I y sometidas a oclusión durante la intervención. Las pruebas epicutáneas con PVP-I al 10% en vaselina fueron positivas en todos los pacientes. Aconsejamos utilizar este vehículo y no agua para el diagnóstico de estas dermatitis de contacto, basados en los resultados de estas pruebas en un grupo control. La prueba abierta repetida con la solución comercial de PVP-I fue negativa. Concluimos en la necesidad de que exista una oclusión, tanto para la aparición de los síntomas clínicos como para el diagnóstico de esta dermatitis de contacto, que puede estar infradiagnosticada
We present 7 cases of postsurgical contact dermatitis due to povidone iodine. The diagnosis was based on the clinical manifestations, the history of exposure, the site of the lesions, and the results of patch tests. This type of dermatitis can develop in the area of surgery or at distant sites exposed to povidone iodine during the surgical intervention. Patch tests with 10% povidone iodine in petrolatum were positive in all patients. Based on the results of the same tests in a control group, we recommend the use of petrolatum rather than water as the vehicle for the diagnosis of this form of contact dermatitis. Repeated open application tests with a commercially available solution of povidone iodine were negative. We conclude that the presence of the solution under occlusion during surgery is necessary both for the symptoms to develop and for the diagnosis to be made. This condition may be underdiagnosed

INTRODUCTION: While the standardization of exploration with photoallergy tests or photopatch testing runs its course in Europe, we have carried out an epidemiological study about the current situation of photoallergy in our country. MATERIAL AND METHODS: We have gathered the results of photopatch testing in seven hospital centres of Madrid, Cataluña, Galicia and Comunidad Valenciana during the years 2004 and 2005. The exploration has included, at least, the standard set of the Spanish Photobiology Group (GEF), with 16 (photo) allergens, that have been irradiated with 10 joules/cm(2). We have assessed the total number of explored patients, their sex, present, past or unknown relevance of positive photopatch testing, cross reactions, and allergens responsible for photosensitization. RESULTS: Of 224 patients explored by photopatch testing, 39.3 % show one or more positive tests. Seventy-one percent (103) were considered relevant with respect to clinical history, 14 cases (9.6 %) were cross reactions, and 28 (19.3 %) were considered of unknown relevance. The most prevalent allergens were nonsteroidal antiinflammatory drugs, specially ketoprophen (43 patients), followed by bencydamine (7 patients) and etofenamate (5 patients). The mixture of four sunscreens from the standard set of the GEF only detected 10 of 16 patients with photoallergy to sunscreens. Photopatch testing of unknown relevance was mainly due to antiseptics (fenticlor) and topical antihistamines. CONCLUSIONS: We propose the modification of the standard set of photoallergens from the GEF, that should include the majority of nonsteroidal antiinflammatory drugs and sunscreens available in Spain. Ketoprophen continues to be the most frequent photoallergen in our country. It is also important for the cross sensitizations that may present. Sunscreens should be explored separately and not in form of a mixture.

BACKGROUND: Since the recent description of immediate hypersensitivity to latex, many cases have been reported, some of them with anaphylactic reactions. The aim of this study is to analyze the clinical findings, diagnostic management and therapeutic procedures in these patients. METHODS: We reviewed the clinical findings in 15 patients with contact urticaria to latex from our files. Use-test with a surgical glove, prick-test trough a rubber glove, RAST to latex and standard patch-tests were performed in each case. RESULTS: We found a M:F ratio of 1:4 (3 males and 12 females) and the mean age at diagnosis was 33 years. Atopic background was present in 60% of cases and 46% were health care workers. Systemic manifestations of allergy were found in 25% of patients. Two cases developed anaphylactic shock. Cutaneous manifestations included localized contact urticaria in 33% of cases, chronic hand eczema and urticaria in 46%, and immediate contact dermatitis in 20%. All cases showed a positive use-test, while prick-test and RAST showed positive results in only 75% of patients. Positive patch-test to rubber accelerators were found in 33% of cases. CONCLUSIONS: Latex immediate hypersensitivity is frequently seen at present. Its prevalence in health care workers is high. Atopic constitution, chronic hand eczema, continuous gloves usage, and contact dermatitis to rubber additives are predisposing factors. Diagnosis can be assessed by clinical findings and use-test, confirming by prick-test and RAST.
