Background/Objectives: Several studies havereported that non-alcoholic fatty liver disease (NAFLD) is more frequent in patients with psoriasis, but few have reviewed the presence of liver fibrosis in those patients. Conclusions:Elastography may be a useful tool along with ultrasound to evaluate liver disease in patients with psoriasis.

Background Since 2009, an increasing number of published cases of allergic contact dermatitis (ACD) from isothiazolinones in Europe was observed, amounting to an epidemic. However, only few studies have assessed the current situation after changes in European regulation. Objectives To analyze the incidence of isothiazolinone‐related ACD in our area in the last decade. Methods A retrospective study analyzed all patients patch tested in the allergy unit in a tertiary hospital in Spain between January 2010 and June 2019. Positive patch‐test reactions to methylchloroisothiazolinone (MCI)/methylisothiazolinone (MI) and/or MI alone were recorded. Results A total of 243 patients (9.55%) with positive patch‐test reactions to MCI/MI and/or MI alone among 2544 consecutively patch‐tested patients were recorded. An initial increase in the prevalence of MCI/MI allergy was observed, from 4.5% in 2010 reaching a peak in 2015, which was followed by a significant decrease until July 2019 with 3.1% prevalence in 2019. Conclusions As shown in our data, regulatory interventions have resulted in a dramatic decrease in the prevalence of MCI and MI ACD, reaching a pre‐epidemic level of 3.1% in 2019.

Dupilumab, a biologic drug approved for the treatment of moderate-to-severe atopic dermatitis, has been associated with resolution or improvement in pre-existing alopecia areata. We report a case of significant improvement of AA after Dupilumab-onset treatment for atopic dermatitis and review the literature.
