Objective: Patients with nonmelanoma skin cancer (NMSC)-ie, basal cell carcinoma (BCC) or squamous cell carcinoma (SCC)-have an increased risk of developing a second skin cancer. The aim of this study was to describe the frequency, incidence per 1000 person-years, and predictors of a second skin cancer in a cohort of patients with NMSC treated with Mohs micrographic surgery (MMS)., Material and Methods: Prospective study of a national cohort of patients with NMSC who underwent MMS at 22 Spanish hospitals between July 2013 and February 2020; case data were recorded in the REGESMOHS registry. The study variables included demographic characteristics, frequency and incidence per 1000 person-years of second skin cancers diagnosed during the study period, and risk factors identified using mixed-effects logistic regression., Results: We analyzed data for 4768 patients who underwent MMS; 4397 (92%) had BCC and 371 (8%) had SCC. Mean follow-up was 2.4 years. Overall, 1201 patients (25%) developed a second skin cancer during follow-up; 1013 of the tumors were BCCs (21%), 154 were SCCs (3%), and 20 were melanomas (0.4%). The incidence was 107 per 1000 person-years (95% CI, 101-113) for any cancer, 90 per 1000 person-years (95% CI, 85-96) for BCC, 14 (95% CI, 12-16) per 1000 person-years for SCC, and 2 (95% CI, 1-3) per 1000 person-years for melanoma. More men than women developed a subsequent skin cancer (738 [61%] vs 463 [39%]). The main risk factors were a history of multiple tumors before diagnosis (relative risk [RR], 4.6; 95% CI, 2.9-7.1), immunosuppression (RR, 2.1; 95% CI, 1.4-3.1), and male sex (RR, 1.6; 95% CI, 1.4-1.9)., Conclusion: Patients have an increased risk of developing a second tumor after MMS treatment of NMSC. Risk factors are a history of multiple tumors at diagnosis, immunosuppression, and male sex., (Copyright © 2022. Publicado por Elsevier España, S.L.U.)

Background and Objectives: Current psoriasis guidelines do not usually include recommendations about first line classical or biologic treatment. The objectives of this study were: to describe shifts in the prescription of the first biological treatment, and to compare treatment withdrawal and rates of adverse events over ten years., Material and Methods: Biobadaderm registry was analyzed to describe: first biological prescription in bio-naïve patients, adverse events rate and reasons for drug withdrawal comparing three periods of time (2008-2010, 2011-2014, 2015-2018)., Results: Anti-TNF drugs were the most prescribed biological drug from 2008 to 2010. Ustekinumab has become the most prescribed first biologic since 2014. The main reasons for drug discontinuation were adverse events, lack of efficacy and remission. In each period any treatment was less likely to be discontinued due to any of these three reasons comparing to the previous period., Conclusions: The present study identifies trends in prescription of the first biological antipsoriatic drug in clinical practice from 2008 to 2018. It suggests that we have become more comfortable with the safety profile and more exigent with the efficacy of the drugs., (Copyright © 2020. Publicado por Elsevier España, S.L.U.)

Sensitive skin has traditionally been viewed as a cosmetic problem or as a purely psychosomatic alteration with a major subjective component. Different studies of its pathophysiologic etiology, however, have shown it to be a complex entity that several authors now consider to be a neurodermatological syndrome. Because of this complexity, skin sensitivity can be difficult to diagnose and treat, particularly considering that it may present with another disease. Simple tools applicable to clinical practice are thus necessary to identify and manage this disease as an independent entity. In this study, we perform a practical review of the most recent scientific advances in the area of sensitive skin that justify it being considered an individual entity, and provide tools for its identification and treatment. We propose diagnostic and treatment algorithms based on evidence from the literature and our experience and expertise., (Copyright © 2019 AEDV. Publicado por Elsevier España, S.L.U.

Background: There is currently little information available on the management of patients with psoriasis in the daily clinical practice of dermatologists in Spain., Objective: The aim of this study was to survey a group of Spanish dermatologists with particular expertise in the management of psoriasis to determine their opinions on the protocols used in routine clinical practice., Material and Methods: A cross-sectional study based on an online survey about the management of psoriasis sent to 75 dermatologists. The survey, which was specifically designed for the study, included 12questions on different aspects of clinical practice in the treatment of moderate to severe psoriasis., Results: The response rate was 96% (n=72). Biologics were the most widely used monotherapy option. In total, 64.3% of respondents reported that their patients used conventional systemic therapies for 1 to 2years before switching to a biologic drug and that the main reason for the switch was unstable control of disease activity. Overall, 85.7% assigned a "high" or "very high" importance to the use of a Psoriasis Area Severity Index score of <3 as a treatment goal. The drugs of choice among the respondents were etanercept for pediatric patients (78.6%), adalimumab and etanercept for patients with psoriatic arthritis (64.3%), and ustekinumab in patients frequently away from home (78.6%) and patients with a history of multiple sclerosis, demyelinating diseases (64.3%), or poor adherence to treatment (71.4%)., Conclusion: This study provides a unique overview of the opinions of a representative sample of expert dermatologists on the current use of biologics for the treatment of psoriasis in Spain., (Copyright © 2018 AEDV.

Introduction and Objectives: Biologic drugs are usually prescribed as second-line treatment for psoriasis, that is, after the patient has first been treated with a conventional psoriasis drug. There are, however, cases where, depending on the characteristics of the patient or the judgement of the physician, biologics may be chosen as first-line therapy. No studies to date have analyzed the demographics or clinical characteristics of patients in this setting or the safety profile of the agents used. The main aim of this study was to characterize these aspects of first-line biologic therapy and compare them to those observed for patients receiving biologics as second-line therapy., Material and Method: We conducted an observational study of 181 patients treated in various centers with a systemic biologic drug as first-line treatment for moderate to severe psoriasis between January 2008 and November 2016. All the patients were registered in the Spanish Registry of Adverse Events Associated with Biologic Drugs in Dermatology., Results: The characteristics of the first- and second-line groups were very similar, although the patients receiving a biologic as first-line treatment for their psoriasis were older. No differences were observed for disease severity (assessed using the PASI) or time to diagnosis. Hypertension, diabetes, and liver disease were all more common in the first-line group. There were no differences between the groups in terms of reasons for drug withdrawal or occurrence of adverse effects., Conclusions: No major differences were found between patients with psoriasis receiving biologic drugs as first- or second-line therapy, a finding that provides further evidence of the safety of biologic therapy in patients with psoriasis., (Publicado por Elsevier España, S.L.U.)

The dermoscopic island is described as a well-defined area in a melanocytic lesion, with a different dermoscopic pattern from the rest of the lesion. It is predictive of melanoma, particularly when the pattern of the island is atypical. We present the reflectance confocal microscopy (RCM) findings in 3 lesions with dermoscopic islands: nevus-associated melanoma, melanocytic nevus, and in situ melanoma. The nevus-associated melanoma and in situ melanoma presented cellular atypia (atypical cells in isolation or forming nests) and architectural distortion on RCM. The nevus presented a dermoscopic island with a typical globular pattern with dense nests and no atypia on RCM. Dermoscopic island is mainly associated with in situ and nevus-associated melanomas. RCM offers good cellular resolution to the depth of the reticular dermis and is useful for diagnosing of melanomas presenting a dermoscopic island., (Copyright © 2017 AEDV.

Background: Regesmohs registry is a nationwide registry including patients evaluated for Mohs surgery in 17 Spanish centres since July 2013. Given that Mohs surgery is the therapy with best results for high risk basal cell carcinoma (BCC) and other skin tumours, we wanted to describe the reasons that lead to some patients being excluded from this therapy and the alternative treatments that they received. These data may be useful to avoid excluding patients for Mohs surgery use, to estimate the healthcare demand of these patients and the demand for Hedgehog inhibitors therapy in this group., Objective: To describe patients excluded for Mohs surgery after pre-surgical assessment, and the treatments that they received., Methods: Regesmohs includes all consecutive patients assessed for Mohs surgery in the participating centres, collecting data on patient characteristics, intervention, and short and long-term results. Patients excluded for Mohs surgery after pre-surgical evaluation were described., Results: 3011 patients were included in Regesmohs from July 2013 to October 2016. In 85, Mohs surgery was not performed as they were considered inadequate candidates. 67 had BCC. Reasons for exclusion were: medical contraindication (27.1%, n=23) low-risk tumour in (18.8%, n=16) and giant tumour and bone invasion (15.3%, n=13). Only 1 patient (1.2%) showed lymph node involvement and no patients had visceral metastases. Of the 85 excluded patients, 29 (34.1%) were treated with conventional surgery, 24 (28.3%) with radiotherapy, 4 (4.7%) with inhibitors of the Hedgehog pathway (only indicated for BCC), and 2 (2.4%) received palliative care. We had no follow-up data on 14 patients (16.5%)., Conclusion: Medical comorbidities were the most common reason for withholding Mohs surgery. Withholding therapy on the basis of distant extension is uncommon. Most excluded patients received simpler therapies: conventional surgery or radiotherapy, with hedgehog inhibitors being a new option., (Copyright © 2017 AEDV. Publicado por Elsevier España, S.L.U.

Introduction: The Spanish Mohs Surgery Registry is used to collect data on the use and outcomes of Mohs micrographic surgery (MMS) in Spain. The aim of this study was to describe perioperative and intraoperative data recorded for MMS procedures performed between July 2013 (when the registry started) and January 2016., Material and Methods: Prospective cohort study of data from 18 hospitals. The data collected included type of anesthesia, surgical technique, hospital admission, number of Mohs stages, management of preoperative risk factors, additional treatments, previous treatments, type of tumor, operating time, and complications., Results: Data were available for 1796 operations. The most common tumor treated by MMS was basal cell carcinoma (85.96%), followed by squamous cell carcinoma (6.18%), lentigo maligna (2.81%), and dermatofibrosarcoma protuberans (1.97%). Primary tumors accounted for 66.9% of all tumors operated on; 19.2% of tumors were recurrent and 13.9% were persistent. The most common previous treatment was surgical. MMS was mostly performed under local anesthesia (86.7% of cases) and as an outpatient procedure (71.8%). The frozen section technique was used in 89.5% of cases. One stage was needed to achieve tumor-free margins in 56.45% of patients; 2 stages were required in 32.1% of patients, 3 in 7.1%%, 4 in 2.7%, and 5 or more in 1.8%. The defect was reconstructed by the dermatologist in 98% of patients and the most common technique was flap closure (47.2%). Intraoperative complications were recorded for just 1.62% of patients and the median (interquartile range) duration of surgery was 75 (60-100) minutes., Conclusion: The characteristics of the patients and tumors treated by MMS are similar to those reported for similar studies in other geographic areas. Lentigo maligna and dermatofibrosarcoma protuberans accounted for a higher proportion of cases in our series, and repair of the surgical defect by a dermatologist was also more common. Operating times in MMS are not much longer than those reported for other procedures and the rate of intraoperative complications is very low., (Copyright © 2017 AEDV.

Acne is a chronic inflammatory disease whose psychosocial effects can greatly impair quality of life. Various scales are used to classify the severity of acne, and several treatment algorithms are currently applied: no consensus on a common scale or treatment guidelines has been reached. A group of Spanish experts therefore met to identify a scale the majority could accept as the most appropriate for classifying severity and treating accordingly. The group chose the following classifications: comedonal acne, mild or moderate papulopustular acne, severe papulopustular acne, moderate nodular acne, and nodular-cystic acne (or acne tending to leave scars). Consensus was reached on first- and second-choice treatments for each type and on maintenance treatment. The experts also issued specific recommendations on antibiotic use (starting with mild or moderate papulopustular acne), always in combination with retinoids and/or benzoyl peroxide. The use of isotretinoin (starting at severe papulopustular or moderate nodular acne) was also covered., (Copyright © 2016 AEDV. Publicado por Elsevier España, S.L.U. All rights reserved.)

Background and Objective: We now have considerable experience in the use of biologic agents to treat psoriasis, but doubts about management arise in certain clinical settings. Surgery is one of them. Although treatment guidelines advise that biologics be suspended before major surgery, data about actual clinical practices and associated complications are lacking. We aimed to analyze current practice in the clinical management of these cases., Methods: Retrospective study of cases in the Biobadaderm database. We analyzed the management of biologic therapy in patients with psoriasis who underwent surgical procedures., Results: Forty-eight of the 2113 patients registered in Biobadaderm underwent surgery. The largest percentage of procedures (31%) involved skin lesions. Biologic treatment was interrupted in 42% of the cases. No postsurgical complications were significantly related to treatment interruption. Likewise we detected no associations between treatment interruption and other variables, such as sex, age, or duration or severity of psoriasis., Conclusion: Continuity of biologic treatment and the risk of postsurgical complications were not associated in this study, although conclusions are limited by the small sample size., (Copyright © 2016 AEDV.

Methotrexate (MTX) is the most frequently used conventional systemic drug in the treatment of psoriasis. Despite over 50years of experience in this setting, certain aspects of the use of this drug in clinical practice are still little standardized and poorly understood. For this reason, a group of 15 experts took part in a consensus development conference to achieve consensus on a series of recommendations on the use of MTX in psoriasis. The guidelines, which were developed on the basis of a systematic review of the literature, were validated by 2 rounds of voting and categorized by level of evidence and grade of recommendation. Before MTX can be used to treat moderate to severe psoriasis, the patient must be evaluated to assess the suitability of the treatment, including consideration of vaccination status and screening for tuberculosis and pregnancy. The recommended starting dose for a patient with no risk factors is 10 to 20mg/wk, the therapeutic dose for most patients is 15mg/wk, and the maximum dose is 20mg/wk. Most patients who respond to treatment will show improvement within 8weeks. Parenteral administration of MTX is desirable when there is a risk of erroroneous dosing, nonadherence, gastrointestinal intolerance, or inadequate response to the therapeutic dose taken orally. Noninvasive methods are preferred for monitoring hepatotoxicity. MTX is a good treatment option for patients with a history of cancer, but is not recommended in patients with chronic hepatitisB infection or individuals who are seropositive for human immunodeficiency virus., (Copyright © 2015.

The clinical distinction between basal cell carcinoma (BCC) and intradermal melanocytic nevus lesions on the face can be difficult, particularly in young patients or patients with multiple nevi. Dermoscopy is a useful tool for analyzing characteristic dermoscopic features of BCC, such as cartwheel structures, maple leaf-like areas, blue-gray nests and dots, and ulceration. It also reveals arborizing telangiectatic vessels and prominent curved vessels, which are typical of BCC, and comma vessels, which are typical of intradermal melanocytic nevi. It is, however, not always easy to distinguish between these 2 conditions, even when dermoscopy is used. We describe 2 facial lesions that posed a clinical and dermoscopic challenge in two 38-year-old patients; confocal microscopy showed separation between tumor nests and stroma and polarized nuclei, which are confocal microscopy features of basal cell carcinoma., (Copyright © 2014 Elsevier España, S.L.U. y AEDV.

Introduction: The Spanish registry of Mohs micrographic surgery started collecting data in July 2013. The aim of the registry is to report on the use of this technique in Spain and the outcomes achieved. In the present article, we describe the characteristics of patients and the tumors treated., Material and Methods: This is a prospective cohort study of patients treated with Mohs micrographic surgery. The participating centers are hospitals where at least one intervention of this type is performed each week. All patients considered for Mohs micrographic surgery in participating centers are included in the registry except those who have been declared legally incompetent., Results: Between July 2013 and October 2014, data from 655 patients were included in the registry. The most common tumor involved was basal cell carcinoma, and the most common histological subtype was infiltrative basal cell carcinoma. Most of the tumors treated were located on the face or scalp, and the most common site was the nose. Almost 40% of the tumors treated were recurrent or persistent, and preoperative tumor size was similar to that reported in other European studies and in Australia. In total, 45.5% of patients had received previous surgical treatment., Conclusion: The findings are similar to those reported in other studies, and the data collected are useful for assessing whether the results of studies carried out elsewhere are applicable in Spain., (Copyright © 2014 Elsevier España, S.L.U. and AEDV.

Psoriatic arthritis, a chronic inflammatory musculoskeletal disease that is associated with psoriasis, causes joint erosions, accompanied by loss of function and quality-of-life. The clinical presentation is variable, with extreme phenotypes that can mimic rheumatoid arthritis or ankylosing spondylitis. Because psoriasis usually presents before psoriatic arthritis, the dermatologist plays a key role in early detection of the latter. As many treatments used in psoriasis are also used in psoriatic arthritis, treatment recommendations should take into consideration the type and severity of both conditions. This consensus paper presents guidelines for the coordinated management of psoriatic arthritis by rheumatologists and dermatologists. The paper was drafted by a multidisciplinary group (6rheumatologists, 6dermatologists, and 2epidemiologists) using the Delphi method and contains recommendations, tables, and algorithms for the diagnosis, referral, and treatment of patients with psoriatic arthritis., (Copyright © 2013 Elsevier España, S.L. and AEDV.

Biologic therapy is a well-established strategy for managing moderate and severe psoriasis. Nevertheless, the high cost of such therapy, the relatively short span of clinical experience with biologics, and the abundance of literature now available on these agents have made evidence-based and consensus-based clinical guidelines necessary. The ideal goal of psoriasis treatment is to achieve complete or nearly complete clearing of lesions and to maintain it over time. Failing that ideal, the goal would be to reduce involvement to localized lesions that can be controlled with topical therapy. Although current evidence allows us to directly or indirectly compare the efficacy or risk of primary or secondary failure of available biologics based on objective outcomes, clinical trial findings cannot be directly translated to routine practice. As a result, the prescribing physician must tailor the treatment regimen to the individual patient. This update of the clinical practice guidelines issued by the Spanish Academy of Dermatology and Venereology (AEDV) on biologic therapy for psoriasis incorporates information from the most recent publications on this topic., (Copyright © 2013 Elsevier España, S.L. and AEDV.

Cutaneous squamous cell carcinoma (cSCC) is the second most common form of skin cancer and its incidence has increased in recent decades. Most cSCCs are successfully treated by surgery, but local and distant metastases develop in approximately 5% of cases; this proportion is higher in certain forms of cSCC with high-risk factors, namely: tumor size >2cm, depth >2mm, Clark level ≥IV, perineural invasion, lymphovascular invasion, poor differentiation, certain histologic subtypes (desmoplastic or adenosquamous carcinoma, invasive Bowen disease, or a cSCC arising in areas of chronic inflammation), immunosuppression, human papillomavirus infection, high-risk anatomic location (pinna of the ear, labial mucosa), expression of certain tumor genes, and inadequate tumor resection. The latest TNM (tumor, lymph node, metastasis) classification of cSCC published by the American Joint Committee on Cancer (AJCC) in the seventh edition of its Cancer Staging Manual now incorporates several of these risk factors to improve disease staging. We review all the factors currently considered to be markers of poor prognosis in cSCC and analyze the new AJCC classification and the different treatment options for high-risk cSCC., (Copyright © 2011 Elsevier España, S.L. and AEDV.

Marginal zone B-cell lymphoma (MZL) is subclassified into extranodal MZL of mucosa-associated lymphoid tissue (including cutaneous lymphomas), splenic MZL, and nodal MZL. We report the case of a 68-year-old man with erythematous-violaceous plaques and nodules. Skin biopsy showed an epidermotropic lymphocytic infiltration and cytology and immunohistochemistry were consistent with MZL. The workup revealed disease in the peripheral blood and bone marrow and massive splenomegaly. Splenectomy confirmed the diagnosis of splenic MZL and led to resolution of the skin lesions. Cutaneous recurrence was treated successfully with chemotherapy and rituximab but caused fatal hepatitis due to hepatitis B virus reactivation. Skin involvement by splenic MZL is uncommon; this form of the disease can present epidermotropism, a very rare finding in primary cutaneous MZL. Treatment consists of splenectomy, which may be associated with chemotherapy and/or rituximab; this treatment may lead to reactivation of latent hepatitis B infection and screening for hepatitis should therefore be performed prior to starting therapy., (Copyright © 2011 Elsevier España, S.L. and AEDV.

Lichen sclerosus is a chronic inflammatory disease that can progress to malignancy. The literature indicates an association with anogenital squamous cell carcinoma and verrucous carcinoma. Two pathogenic pathways, differentiated vulvar and penile intraepithelial neoplasias, which have recently been described in relation to squamous cell carcinoma, are both highly associated with genital lichen sclerosus independently of human papilloma virus (HPV) infection. Furthermore, tumor-promoting molecular changes unrelated to HPV infection have been demonstrated and may explain the malignant potential of lichen sclerosus. The possible relationship between HPV and genital lichen sclerosus currently remains open to discussion, and the prognostic importance of the overlapping of these 2 diseases is still unclear. This review considers the relationship between lichen sclerosus and squamous cell and verrucous carcinomas, the possible oncogenic mechanisms involved, and their possible association with HPV infection., (Copyright © 2011 Elsevier España, S.L. and AEDV.

Background and Objectives: Treatment of mucosal vascular lesions is a challenge for dermatologists, although various approaches have proven efficacy, including surgery, sclerotherapy, intralesional injection of corticosteroids, transfixion, and laser therapy. The aim of this study was to describe the results of treatment with neodymium:yttrium-aluminum-garnet (Nd:YAG) laser in 11 patients with venous malformations and varicosities., Patients and Methods: We describe the use of variable-pulse Nd:YAG to treat venous malformations or varicosities in the oral or genital mucosa of 8 women and 3 men seen in our hospital over a 1-year period., Results: The following laser parameters were used: wavelength, 1064 nm; fluence, 100 to 200J/cm(2); spot diameter, 3 to 5mm; and pulse duration, 30 to 65 ms. The size of the lesions ranged from 5 to 30 mm. In all cases, a clearance of 75% to 100% was achieved in a single session with excellent healing and no significant side effects., Conclusions: Given its efficacy and ease of use, Nd:YAG may become a treatment of choice for mucosal vascular lesions. Comparative studies are now required to assess its potential superiority over other treatment options., (Copyright © 2010 Elsevier España, S.L. y AEDV. All rights reserved.)

During the Nazi period experimentation on human subjects and the elimination of individuals considered to be unproductive members of society were carried out in a systematic fashion. Involved in these practices were many physicians, including dermatologists whose names are linked in one way or another to their specialty. Some, such as Reiter, are very well known. This review attempts to bring to light the identities behind the names we have given to diseases, clinical and histological signs, and syndromes in dermatology., (Copyright © 2010 Elsevier España, S.L. y AEDV.

Background and Objectives: The withdrawal of marketing authorization for efalizumab by the European Medicines Agency in February, 2009 provided a unique opportunity to assess the course of disease in patients who were not subject to the selection criteria and biases that were common in the pivotal trials. The aim of this study was to evaluate the course of psoriasis following forced suspension of efalizumab in a group of patients treated in normal clinical practice. As secondary objectives, we sought to assess the relationships between clinical characteristics, treatment response, and disease course during efalizumab treatment and 12 and 24 weeks after suspension., Patients and Methods: Information on the epidemiological profile and disease course during treatment and following suspension of the drug was collected from a group of patients treated with efalizumab. Statistical analyses were performed to identify predictive factors., Results: One hundred forty-seven patients from 12 Spanish hospitals were included in the study. During treatment, 4% of patients were diagnosed with generalized inflammatory flares. Most patients could be classified as having a good (55%) or moderate (18%) response to treatment. Rebound following withdrawal of efalizumab was observed in 30% of patients. The likelihood of rebound was independent of clinical characteristics, treatment response, or therapeutic approach used by the dermatologist following suspension., Conclusions: There was a high frequency of rebound following suspension of efalizumab, exceeding the rate reported in pivotal trials. This is particularly noteworthy given the large proportion of patients with a good response to treatment and therefore believed to have a better prognosis. Other significant findings were the higher frequency of positive treatment response than observed in previous studies (possibly influenced by the mean treatment duration) and the high frequency of generalized inflammatory flares., (2010 Elsevier España, S.L. y AEDV.

Novel treatment strategies and new information concerning the management of moderate to severe psoriasis justify a reassessment of the role of the classic therapies in this setting. This consensus statement evaluates narrowband UV-B therapy, which is currently considered the phototherapy option of choice in psoriasis because of its risk-to-benefit ratio. The role of excimer laser and photodynamic therapies are also discussed. These targeted therapies are still only available in a small number of centers in Spain and are used principally in the treatment of localized and recalcitrant forms of psoriasis. We discuss the efficacy and safety of phototherapy as well as treatment regimens, combination therapy, and clinical considerations relating to the characteristics of the patient or the disease., (Copyright © 2010 Elsevier España, S.L. y AEDV.

Background and Objectives: The Working Group on Psoriasis of the Spanish Academy of Dermatology and Venereology has initiated BIOBADADERM, a registry of patients with psoriasis receiving treatment with biologic drugs, in order to assess the long-term risk of adverse events (AEs)., Material and Methods: A multicenter study was undertaken in 2 cohorts of patients with psoriasis: patients receiving biologic therapy and patients receiving nonbiologic systemic therapy other than phototherapy. Similar numbers of patients were included in each group. Information was recorded on demographic and clinical variables, treatment, and relevant AEs. The risk of specific AEs was determined by comparison of the frequencies for those events in the 2 cohorts., Results: Data on the 2 cohorts were evaluated for the period from October, 2008 to November, 2009 alongside retrospective data on patients treated with biologics since 2005. Thirteen Spanish hospitals participated in the study. A total of 632 patients were included in the analysis: 417 treated with biologic drugs and 215 controls. Suspension of biologic therapy due to AEs was rare (72 cycles, 10%). A total of 232 AEs were reported in patients receiving biologic therapy. The majority were not serious. The most frequent AEs were infections (mostly upper respiratory tract infections and nasopharyngitis), followed by conditions affecting the skin or subcutaneous tissue. Forty-three AEs were reported in control subjects. The most frequent events were metabolic and nutritional abnormalities and abnormal transaminase levels. Comparison of the incidence of any AE in patients treated with biologics compared with control subjects revealed a relative risk of 2.2 (P<.001) The relative risks of infections or infestations and disorders of the skin or subcutaneous tissue in patients receiving biologic drugs were 23 (P<.01) and 4.9 (P<.05), respectively., Conclusions: Patients treated with biologic drugs had a greater number of AEs, particularly infections and skin conditions. Definitive conclusions, however, are difficult to draw due to the small number of patients included in the registry, particularly in the control cohort, and the short follow-up period. Differences in the percentages of events reported by the different hospitals reveal the difficulties associated with the concept of AEs in clinical practice and highlight the need to harmonize criteria in the future. Since the problems identified in this analysis should be overcome in future years, we expect BIOBADADERM to become an important source of information on the safety profile of biologic drugs in dermatology., (Copyright © 2010 Elsevier España, S.L. y AEDV.

Psoriasis, a chronic multifactorial inflammatory disease that develops in genetically predisposed individuals, affects approximately 1.5% of the Spanish population. This disease has a negative impact on patients' quality of life, and long-term therapy is often required to control the symptoms. In addition to the classical systemic treatments (methotrexate, acitretin, cyclosporine, and ultraviolet light), the group of drugs known as biologics (etanercept, infliximab, adalimumab, and ustekinumab) provides the dermatologist with an expanded therapeutic armamentarium, thereby improving the likelihood of controlling psoriasis in patients with severe and/or extensive disease. Methotrexate, a classic antipsoriatic drug, is still very useful either as single-drug therapy or in combination with other systemic drugs, particularly as a rescue therapy or combined with biologics. This article aims to establish the role of methotrexate in the treatment of psoriasis. We considered it of interest to develop guidelines for using methotrexate in the management of psoriasis with a view to ensuring the safe and proper use of this drug in the management of psoriasis. This document was developed by consensus among members of the Psoriasis Group of the Spanish Academy of Dermatology and Venereology.

Objective: To describe the clinical management of psoriatic arthritis for patients being treated by dermatologists and rheumatologists in Spain., Methods: Multicenter, retrospective, naturalistic observational study in which demographic and clinical variables were recorded for patients diagnosed with psoriatic arthritis. Data referred to the previous 12 months and were collected during a single visit with the physician., Results: A total of 266 patients were enrolled; 78.1% were being treated by rheumatologists and 21.9% by dermatologists. The data covered 1138 visits. The main reason for consulting a physician was to monitor psoriatic arthritis (82.7% of the visits). The most widely used examination was to determine the tender- and swollen-joint count (73.1%). The tests most frequently ordered were acute-phase reactants: erythrocyte sedimentation rate (79.8%) and C reactive protein level (74.5%). Affected body surface area and the Psoriasis Area and Severity Index were the main assessments used by dermatologists. Rheumatologists tended to examine the joints and record biochemical markers. A disease-modifying antirheumatic drug was prescribed for 71.1% of the patients; 51.8% were prescribed a biologic agent (61.5% in combination with another treatment). Treatment approach differed by specialty and was modified if response was nil or partial (the rationale for 45.1% of all changes)., Conclusion: Differences in the management of psoriatic arthritis in dermatology and rheumatology were evident in both diagnostic and treatment approaches. These 2 specialties should cooperate to establish common practice guidelines for use in Spain., (Copyright © 2009 Elsevier España, S.L. y AEDV. All rights reserved.)

Etanercept has been approved for the treatment of moderate-severe plaque psoriasis. This is the most frequent form of psoriasis (80%). In other forms of psoriasis, the use of etanercept, as that of other biological therapies, has been published in an isolated way with satisfactory results. We present a patient with palmoplantar pustulous psoriasis palmoplantar refractory to multiple treatments (topical corticosteroids, phototherapy, methotrexate) who responded favorably to the use of 50 mg biweekly doses of etanercept. The patient has maintained total remission of the lesions 6 months after having terminated treatment. We review the cases published on palmoplantar psoriasis treated with etanercept and also the use of this drug in other forms of pustular psoriasis and of erythrodermal psoriasis.

The common use of etanercept in the treatment of psoriasis entails that the dermatologist may encounter situations in which the need for temporary interruption of treatment may arise. In this article, an attempt has been made to establish guidelines on the interruption of etanercept within some circumstances, such as surgeries or vaccinations, the suspension time and when to reintroduce the drug.

Laser systems and other energy sources for home use are being developed and will have an exponential growth in the coming years. It is in the field of laser hair removal and hair regrowth where these lasers and intense pulsed light systems for home use are gaining most ground. There are few studies supporting their efficacy and safety and there are still no long term studies. Currently these systems do not require medical prescription and can be purchased in the same way as any over-the-counter product. Although they are not a substitute for professional medical systems, they will play an important role in the treatment of medical and cosmetic conditions, and dermatologists should know about them. Technological progress and commercial and market pressures will encourage the development of more sophisticated devices and broaden the cosmetic and medical indications. Appropriate use and rigorous long-term studies would be desirable to better define their safety and efficacy.

Background: Biologic therapies have been a major breakthrough in the treatment of psoriasis because they are more selective and have a better short-term and medium-term safety profile. There are reliable data to support both the efficacy and the safety of these drugs. However, it is always useful to report the clinical experience of dermatologists who are experts in the use of biologic agents to treat psoriasis, particularly with regard to their safety., Material and Methods: We present the results of a survey administered to the members of Spanish Psoriasis Group and based on a series of questions referring to the clinical safety of these agents. A total of 988 patients treated with efalizumab, infliximab, etanercept, and adalimumab were reported by 15 members of the group., Results: There was a particularly high proportion of reactions (34%) to infliximab infusions. Blood test abnormalities were detected in 13.25% of patients and infections in 12.24%, with one case of pulmonary tuberculosis. Attention is drawn to the adverse effects profile of efalizumab: de novo arthritis in 5.8% and rebound in 20.9% of patients., Conclusion: The safety data provided by our study should be taken into account in view of the large number of patients recruited by dermatologists experienced in the use of this type of therapy.
