Interleukin (IL)-9 is present in atopic dermatitis (AD) lesions and is considered to be mainly produced by skin-homing T cells expressing the cutaneous lymphocyte-associated antigen (CLA). However, its induction by AD-associated triggers remains unexplored. Circulating skin-tropic CLA and extracutaneous/systemic CLA memory T cells cocultured with autologous lesional epidermal cells from AD patients were activated with house dust mite (HDM) and staphylococcal enterotoxin B (SEB).

The phenomenon affects the quality of care, increases doctors' workloads and can lead to burnout.This study presents the results of an educational intervention for primary care physicians, aimed at helping them to decrease the prevalence rate of excessive attendance by patients at their centres.
View Article and Find Full Text PDFBackground: Topical imiquimod has been shown to be an effective treatment for extramammary Paget disease (EMPD), although available evidence supporting its use is based on case reports and small series of patients.
Objectives: To investigate the therapeutic outcomes and analyse potential clinicopathological factors associated with the imiquimod response in a large cohort of patients with EMPD.
Methods: Retrospective chart review of 125 patients with EMPD treated with imiquimod at 20 Spanish tertiary-care hospitals.
An 11-year-old boy presented generalized eruptive syringomas (ESs) associated with multiple milia-like whitish palmar papules corresponding to dermal calcium deposits. A relationship between calcium deposits distribution to an underlying eccrine duct was noted on pathology. The observation of dermal calcium deposits and its association with generalized ESs may support a possible sweat duct origin of this uncommon and peculiar form of superficial calcinosis cutis.

Methods: We performed high-throughput RNA sequencing of the TR alpha (TRA) and beta (TRB) genes focusing on the complementarity-determining region 3 (CDR3) in 11 SS and one erythrodermic mycosis fungoides (MF) patients.
Background: Autoimmunity contributes to the pathogenesis of chronic spontaneous urticaria (CSU). The subtyping of CSU has revealed an autoimmune form of CSU. Despite autoimmune diseases having been associated with CSU, there are few prospective studies that have evaluated the characteristics and biomarkers of patients with CSU and autoimmune disease in a real-life practice setting.

Objectives: To assess the DSS and outcomes of surgical and nonsurgical therapeutic modalities in a large cohort of EMPD patients.
Methods: Retrospective chart review of EMPD patients from 20 Spanish tertiary care hospitals.
