Cross‐reactivity between thiuram disulfides and dithiocarbamates. A study of TETD and ZDEC using mouse models

Contact Dermatitis, Volume 92, Issue 2, Page 137-144, February 2025.
When mice are sensitized with ZDEC or TETD, a significant cross‐reaction occurs between both chemicals with an increased ear thickness after challenge. Cross‐reactivity reactions were also observed in the submandibular and cervical draining lymph nodes with proliferation of both CD4+ T cells and CD8+ T cells when TETD‐sensitized mice were challenged ...

The role of ATP citrate lyase in myelin formation and maintenance

Glia, Volume 73, Issue 1, Page 105-121, January 2025.
Main Points We have tested if mitochondrial substrates of Acetyl CoA generation (e.g. glucose‐derivated pyruvate, amino acids, fatty acids) are required for lipid synthesis in myelinating Schwann cells using a knockout of the ATP citrate lyase (Acly) gene.

A cross‐sectional study of the vulval dermatology clinic population over a 4‐year period and development of a national vulval disease database

Skin Health and Disease, Volume 4, Issue 6, December 2024.
Abstract Background Vulval disease significantly impacts quality of life but is historically under‐researched. The epidemiology and aetiology of many vulval conditions is unclear. Data to optimise patient care are lacking. Objectives To describe the population attending a specialist vulval dermatology clinic and achieve consensus amongst vulval experts

Differential diagnosis of contact dermatitis: A practical‐approach review by the EADV Task Force on contact dermatitis

Journal of the European Academy of Dermatology and Venereology, Volume 38, Issue 9, Page 1704-1722, September 2024.
Abstract The diagnosis of eczema (‘dermatitis’) is mostly clinical and depends on the clinical history and exploratory objective findings (primary lesions, patterns). Contact dermatitis remains as an important condition in the group of eczematous disorders, with important socioeconomic and occupational relevance.
