Psoriasis dermatitis, a common phenotype of early forms of both psoriasis and atopic dermatitis in children: A prospective multicenter study.

Background: Psoriasis (Ps) and atopic dermatitis (AD) are chronic systemic immune-mediated diseases that can coexist in an overlapping condition called psoriasis dermatitis (PD). PD patients have intermediate lesions with characteristics of both Ps and AD. PD is very rare in adults but much more frequent in children.

Patch Testing in Patients With Severe Atopic Dermatitis Treated With Dupilumab: A Multicentric Approach in Spain.

Persistent localized dermatitis (PLD) or eczema flare-ups (EF) may occur in atopic dermatitis (AD) patients treated with dupilumab. They may reflect concomitant allergic contact dermatitis (ACD) exposed by the inhibition of the Th2 pathway by dupilumab in some cases. To evaluate the prevalence and etiology of these events and the impact of dupilumab on patch test outcome.

Herpes Simplex Virus Infection in Neonates Born to Asymptomatic Mothers: A Case Series.

Neonatal herpes is a rare condition and it is normally acquired through vertical transmission in the peripartum period. Delayed diagnosis and treatment of this condition are associated with high morbidity and mortality. We present five cases of neonatal herpes in infants born to asymptomatic mothers.

Topical 15% Resorcinol Is Associated with High Treatment Satisfaction in Patients with Mild to Moderate Hidradenitis Suppurativa.

Background: Topical 15% resorcinol is commonly used in clinical practice for the treatment of nodules and abscesses in patients with hidradenitis suppurativa (HS). It has been shown to be clinically effective in some small studies, but data on satisfaction perceived by patients are lacking. The Treatment Satisfaction Questionnaire for Medication (TSQM) version 1.

Frequency of sensitization to the individual fragrances of fragrance mix I and II according to the factors included in the MOAHLFA index.

Background: Fragrances constitute the second most frequent cause of allergic contact dermatitis in Spain.

Objectives: To determine the rate of sensitization to the individual fragrances of fragrance mix (FM) I and FM II for each of the demographic and clinical factors included in the MOAHLFA (male, occupational dermatitis, atopic dermatitis, hand dermatitis, leg dermatitis, facial dermatitis, age) index.

Methods: We conducted a 5-year retrospective study in 23 Spanish centres.

No SARS-CoV-2 antibody response in 25 patients with pseudo-chilblains.

Chilblain-like acral lesions have been identified in some coronavirus disease 2019 (COVID-19) patients. It has been suggested that these pseudo-chilblains could be a specific marker of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Most patients with these lesions have had negative polymerase chain reactions (PCRs), but some authors believe serology tests are likely to give positive results.
