Background: Previous small reports suggested the role of ultraviolet (UV)-B in the management of cutaneous lichen planus.
Objective: To summarize our experience with UVB in a relatively large study group looking specifically into predictive factors for complete response and the long-term relapse rates.
Methods: A retrospective analysis of 50 patients with generalized cutaneous lichen planus, treated by broad or narrow band UVB.
Results: Seven and 43 patients were treated by broad and narrow band UVB, respectively. Complete response was achieved in 70% and 85% of those were still in remission after a median of 34.7 months. The complete response rate and the need for higher cumulative exposure doses were not influenced by sex, age, skin type, presence of additional diseases, failure of previous treatment or disease duration.
Limitations: This is a retrospective non-randomized analysis of a usually self-limiting disease.
Conclusion: UVB is a safe and efficient treatment option for generalized cutaneous lichen planus.

The role of skin microbiota in lichen planus from a Mendelian randomization perspective.
Arch Dermatol Res

Hospital of Chengdu University of Traditional Chinese Medicine, Chengdu, China.
Lichen planus is a chronic skin lesion characterized by pruritic violaceous papules, which has a high risk of morbidity. Skin microbiota plays an important role in the maintenance of cutaneous mucosal barrier and human health and immune homeostasis. Studies have shown that skin microbiota may play a role in the pathogenesis of lichen planus, but it is not yet clear.

Dr. Phillip Frost Department of Dermatology and Cutaneous Surgery, University of Miami Miller School of Medicine, Miami, FL.
Frontal Fibrosing Alopecia (FFA) poses a distinct dermatological challenge with epithelial-mesenchymal transition (EMT) at its core, driving follicular cell transformation and fibrotic changes. Genetic studies highlight significant associations, while environmental triggers, such as implicated cosmetic products (sunblock, personal hair care products, and moisturizers), introduce complexity. Managing FFA proves daunting due to its chronic and unpredictable nature.

Background: Dermatomyositis is a chronic autoimmune disease with distinctive cutaneous eruptions and muscle weakness, and the pathophysiology is characterised by type I interferon (IFN) dysregulation. This study aims to assess the efficacy, safety, and target engagement of dazukibart, a potent, selective, humanised IgG1 neutralising monoclonal antibody directed against IFNβ, in adults with moderate-to-severe dermatomyositis.
Methods: This multicentre, double-blind, randomised, placebo-controlled, phase 2 trial was conducted at 25 university-based hospitals and outpatient sites in Germany, Hungary, Poland, Spain, and the USA.
Utilization and prescription patterns of topical steroids: a study at dessie comprehensive specialized hospital, Ethiopia.
Arch Dermatol Res
January 2025
Department of Pharmacy, College of Medicine and Health Sciences, Wollo University, Dessie, Ethiopia.
Background: Topical steroids are widely used in dermatology for their anti-inflammatory and immunosuppressive effects, but misuse can cause skin thinning and systemic issues. In Ethiopia, where skin conditions are common, understanding how topical steroids are prescribed and used is essential for ensuring their safe and effective use.
Objective: The study aimed to assess topical steroids' prescription and utilization pattern in Dessie Comprehensive Specialized Hospital (DCSH) from February 1 to May 30, 2024.
Updates on Psoriasis in Special Areas.
J Clin Med

2nd Department of Dermatology, Colentina Hospital, "Carol Davila" University of Medicine and Pharmacy, 050474 Bucharest, Romania.
Special areas of involvement in psoriasis include the scalp region, the palms and soles, genital areas, as well as intertriginous sites. The involvement of these topographical regions is associated with important physical and emotional implications, resulting in reduced quality of life, social isolation, and work disability. Palms and soles can be affected as part of the generalized form of psoriasis or can be exclusively affected as palmo-plantar psoriasis.
