Mucocutaneous lesions are the most frequent symptoms of Behçet’s disease (BD). Recently, new therapies are being used to treat refractory cases, but the effect of these treatments on mucocutaneous manifestations has been scarcely reported. Our objective was to describe the mucocutaneous response to the different therapies used to treat BD in routine clinical practice. We retrospectively reviewed the clinical records of all patients diagnosed with BD seen at our institution between January 2010 and January 2022. Patients with BD without mucocutaneous manifestations were excluded. We included 109 patients diagnosed with BD: 51 males (46.8%) and 58 females (53.2%). The mean age at diagnosis was 31.58 years (standard deviation (SD) 12.110) and the mean time of disease evolution was 14.94 years (SD 11.094). Oral ulcers were the most frequent symptom present in 100% of patients, followed by genital ulcers (GU) in 76.1% of patients. Twenty-four patients (22%) had severe mucocutaneous symptoms (>12 lesions/year) before treatment. We found that among patients with GU there was a higher prevalence of episodes of posterior uveitis and venous thrombosis ( p = 0.011 and p = 0.045 , respectively). In our series, we observed a lower complete cutaneous response to colchicine in patients with GU, pathergy or severe mucocutaneous symptoms ( p < 0.05 ). Regarding the choice of a TNF-α inhibitor, we observed a lower prevalence of complete cutaneous response to adalimumab among patients with GU (53.3% complete response in patients with GU vs. 100% in patients without GU, p = 0.022 ), whereas no differences were found between clinical characteristics in the response to infliximab.

Background Tralokinumab was recently approved for the treatment of moderate-to-severe atopic dermatitis (AD) and is the first selective interleukin (IL)-13 inhibitor that specifically neutralizes IL-13 with high affinity. Objectives To determine the real-life short-term effectiveness and safety of tralokinumab treatment in patients with moderate-to-severe AD. Methods A multicentre retrospective study was conducted including adult patients with moderate-to-severe AD who started tralokinumab treatment from 1 April to 30 June 2022 in 16 Spanish hospitals. Demographic and disease characteristics, severity and quality of life scales were collected at the baseline visit and at weeks 4 and 16. Results Eighty-five patients were included. Twenty-seven patients (32%) were non-naive to advanced therapy (biological or Janus kinase inhibitors inhibitors). All included patients had severe disease with baseline Eczema Area and Severity Index (EASI) scores of 25.4 (SD 8.1), Dermatology Life Quality Index (DLQI) 15.8 (5.4) and peak pruritus numerical rating scale (PP-NRS) 8.1 (1.8) and 65% had an Investigator’s Global Assessment (IGA) of 4. At week 16, there was improvement on all scales. The mean EASI decreased to 7.5 (SD 6.9, 70% improvement), SCORing Atopic Dermatitis improved 64% and PP-NRS, 57%. Also, 82%, 58% and 21% of the patients achieved EASI 50, 75 and 90, respectively. The percentage of EASI 75 responders was significantly higher among the naive vs. non-naive groups (67% vs. 41%). The safety profile was acceptable. Conclusions Patients, with a long history of disease and prior multidrug failure, showed a good response to tralokinumab, confirming clinical trial results.

Resumen Con el progresivo control de la pandemia por SARS-CoV-2, los miembros del Grupo Espanol de Investigacion en Dermatitis de Contacto y Alergia Cutanea (GEIDAC) realizan una propuesta sobre cuales van a ser los requisitos, las limitaciones y los condicionantes para reanudar el servicio en las unidades de dermatitis de contacto en un escenario en el que se presume la persistencia del virus, con episodios ocasionales o estacionales de exacerbacion. Se aconseja ajustar el numero de pruebas epicutaneas (PE) a las posibilidades de cada centro y la revision de los casos en lista de espera para priorizar a los pacientes en funcion de la gravedad y la urgencia. Se ofreceran, si es factible, metodos telematicos para los documentos relativos a las PE (informacion, pautas, documentos de consentimiento informado). De estar disponible, puede ofrecerse la opcion de realizar una primera visita telematica. Igualmente, en pacientes seleccionados puede llevarse a cabo una televisita en las visitas de lectura a traves de imagenes realizadas por el paciente o mediante una videovisita que permita visualizar el resultado de la exploracion. Estas acciones permitiran reducir el numero de visitas presenciales, aunque no el tiempo dedicado y asignado al facultativo para los actos medicos. Todas estas recomendaciones son sugerencias y se adaptaran a los requisitos y a las posibilidades de cada centro sanitario

Autoinflammatory diseases include disorders with a monogenic cause and also complex conditions associated to polygenic or multifactorial factors. An increased number of both monogenic and polygenic autoinflammatory conditions have been identified during the last years. Although skin manifestations are often predominant in monogenic autoinflammatory diseases, clinical and histopathological information regarding their dermatological involvement is still scarce. Monogenic autoinflammatory diseases with cutaneous expression can be classified based on the predominant lesion: (1) maculopapular rashes or inflammatory plaques; (2) urticarial rashes; (3) pustular, pyogenic or neutrophilic dermatosis-like rashes; (4) panniculitis or subcutaneous nodules; (5) vasculitis or vasculopathy; (6) hyperkeratotic lesions; (7) hyperpigmented lesions; (8) bullous lesions; and (9) aphthous lesions. By using this classification, this review intends to provide clinical and histopathological knowledge about cutaneous involvement in monogenic autoinflammatory diseases.

Atopic dermatitis is a chronic, pruritic, relapsing inflammatory disease with a complex etiopathogenesis. Alterations of the epidermal barrier function together with a predominantly type 2 altered immune response are responsible for the heterogeneous clinical manifestation. Although pruritic eczematous plaques represent the most frequent phenotype, several others are also characteristic. The diagnostic of the disease relies on clinical aspects, and no complimentary tests are needed. In the literature, we can find a significant number of diagnostic and screening biomarkers; however, severity ones are the most reliable and applicable. Patient-tailored treatment is mandatory, as not all the patients equally respond to the same drugs. The newly released therapies, as well as those under investigation, give hope to AD patients.

Langerhans cell histiocytosis (LCH) identifies a spectrum of disorders that are classified according to the organs involved (single- or multi-organ disease) and the presence or absence of organ failure. Patients younger than 2 years with a multisystem disease have a significantly higher mortality rate than older children.1 Nail involvement in LCH is extremely uncommon and rarely reported. To our knowledge, 18 cases have been documented in the literature to date. According to most cases reported, it is thought to indicate a poor prognosis.2, 3, 4, 5, 6 We report the case of a child with nail lesions, which led to a diagnosis of LCH.

Actinic keratosis (AK) is a chronic, progressive disease of the skin that has undergone long-term sun exposure. The affected areas contain visible and subclinical nonvisible sun damage resulting in epidermal keratinocyte dysplasia, known by many as ‘field cancerisation’ (1), which is prone to AKs and sun-related skin cancer (2). Thus, visible AKs are clinical biomarkers for a photo-damaged field with subclinical damage associated with the unpredictable risk of progression to invasive squamous cell carcinoma (iSCC) (3). The aim of this multiexpert opinion article is to provide a discussion succinctly highlighting the clinical gaps for optimal management of AK: the lack of a universal definition and the need for a standardised grade assessment of AK/field cancerisation that also takes into account individual risk.
