Compared Burden of Psoriasis, Atopic Dermatitis, Hidradenitis Suppurativa, and Chronic Urticaria: Baseline Characteristics of the Patients Included in the OMCCI Cohort - A French, Prospective Multicenter Study of Chronic Inflammatory Dermatoses.

Introduction: Chronic inflammatory dermatoses (CIDs) can significantly affect patients' lives. The Observatory of Chronic Inflammatory Skin Diseases (OMCCI) cohort was initiated to quantify the impact and disease evolution of four CID over 4 years' follow-up; at least 1,000 patients per CID are planned to be enrolled. The objective of this study was to present baseline characteristics of patients included in the OMCCI cohort between December 2020 and September 2022.

Localization, Morphologic Features, and Chemical Composition of Calciphylaxis-Related Skin Deposits in Patients With Calcific Uremic Arteriolopathy.

Importance: Calcific uremic arteriolopathy (CUA), a rare, potentially fatal, disease with calcium deposits in skin, mostly affects patients with end-stage renal disease who are receiving dialysis. Chemical composition and structure of CUA calcifications have been poorly described.

Objectives: To describe the localization and morphologic features and determine the precise chemical composition of CUA-related calcium deposits in skin, and identify any mortality-associated factors.

Effectiveness and safety of dupilumab for the treatment of atopic dermatitis in a real-life French multicenter adult cohort.

Background: Dupilumab is the first biologic available to treat atopic dermatitis (AD). Its effectiveness and safety were demonstrated in clinical trials.

Objective: We sought to assess the effectiveness and safety of dupilumab in adults with AD in a real-life French multicenter retrospective cohort.
