Contact allergy to and allergic contact dermatitis from formaldehyde and formaldehyde releasers: A clinical review and update.

Contact Dermatitis 2022 Jul 17;87(1):20-27. Epub 2022 Mar 17.

Department of Dermatology, University Hospital Antwerp (UZA) and Research group Immunology, INFLA-MED Centre of Excellence, University of Antwerp, Antwerp, Belgium.

This review aims to provide a clinically useful update regarding the role of formaldehyde (FA) and its five main releasers (FRs) quaternium-15, diazolidinyl urea, DMDM hydantoin, imidazolidinyl urea, and 2-bromo-2-nitropropane-1,3-diol (bronopol) in contact allergy and allergic contact dermatitis. These ubiquitous preservatives are still often present, and sometimes undeclared, in cosmetics, pharmaceuticals, medical devices, household detergents, and chemical (industrial) products. In Europe, the use of free FA and quaternium-15 in cosmetics is forbidden and contact allergy rates have been found to be stable to decreasing. Read More

Dupilumab: A Review of Present Indications and Off-Label Uses.

J Investig Allergol Clin Immunol 2022 Apr 3;32(2):97-115. Epub 2021 Mar 3.

Allergy Service, Hospital Universitario de Salamanca, Spain.

Recent advances in our understanding of T2 inflammation have revealed more diseases in which T2 inflammation is involved. Dupilumab is a recently developed monoclonal antibody that blocks signaling of IL-4 and IL-13, both of which are crucial cytokines in the T2 response. New possible indications are increasingly explored and include skin diseases, such as prurigo nodularis, nummular eczema, allergic contact dermatitis, chronic hand eczema, spontaneous chronic urticaria, bullous pemphigoid, alopecia areata, and Netherton syndrome, as well as respiratory diseases, such as allergic bronchopulmonary aspergillosis, chronic eosinophilic pneumonia, and allergic rhinitis.

When working with dermatology patients, the question sometimes arises which diagnostic tests and tools should be used for workup, particularly in cases of chronic urticaria (CU) and discoid nummular eczema, where the treatment of associated systemic diseases and infections may be crucial for patient outcome. The aim was to investigate retrospectively the influence of associated diseases on skin disease outcomes based on medical records of CU and nummular eczema patients in comparison to controls. We included patients admitted to our Dermatology Department over a 6-year period and analyzed their laboratory findings, related factors and outcomes recorded after two years of workup and treatment.

Effectiveness of dupilumab for the treatment of nummular eczema phenotype of atopic dermatitis in adults.

Dermatol Ther 2020 05 11;33(3):e13290. Epub 2020 Mar 11.

Department of Health Sciences Vincenzo Tiberio, University of Molise, Campobasso, Italy.

Nummular eczema (NE) is currently considered as one of the clinical phenotypes of atopic dermatitis (AD) of the adult. In this multicentre study, 30 adult patients (age ≥ 18 years) affected with nummular-like AD were treated with dupilumab, a monoclonal antibody against the receptor for interleukin(IL)-4 and IL-13. The evaluation of the results after 16 weeks of treatment showed a significant improvement of the disease, as demonstrated by reduction in Eczema Area Severity Score (EASI), visual analogue score (VAS) of pruritus, and Dermatology Life Quality Index (DLQI) scores.

Assoc. Prof. Halil Tekiner, MD, PhD, Department of the History of Pharmacy and Ethics, Erciyes University School of Pharmacy , 38280 Kayseri, Turkey;

The German dermatologist Paul Gerson Unna (1850-1929) is a prominent figure in the history of medicine for pioneering modern dermatopathology and dermotherapy (Figure 1) (1). Aside from writing extensively on anatomy, histopathology, and treatment of skin diseases, he contributed to medicine in many other ways: he originated the idea of using coated pills to enhance local absorption in the intestine, introduced ammonium bituminosulfonate (ichthyol) and resorcinol into medicine, and described several skin conditions including seborrheic dermatitis. Moreover, in 1881 he established a private clinic in Hamburg, Germany, which became a leading expert center in the diagnosis and treatment of skin disorders, hosting postgraduate physicians from all over the world for training (2).
