Radiodermatitis is an inevitable side effect of radiotherapy in cancer treatment and there is currently no consensus on effective drugs for treating the condition. Vitamin B is known to be effective for repairing and regenerating damaged skin. However, there are few studies on the use of Vitamin B for treating radiodermatitis. This study explored the therapeutic efficacy and mechanism of action of Vitamin B ointment on radiodermatitis. A porcine model of grade IV radiodermatitis was established. The ointment was applied for 12 weeks after which histological staining, transmission electron microscopy, RT-qPCR, western blotting, and gene sequencing were performed for the evaluation of specific indicators in skin samples. After 12 weeks of observation, the Vitamin B treatment was found to have significantly alleviated radiodermatitis. The treatment also significantly reduced the expression levels of NF-κB, COX-2, IL-6, and TGF-β in the skin samples. The pathways involved in the effects of the treatment were identified by analysing gene expression. In conclusion, Vitamin B ointment was found to be highly effective for treating radiodermatitis, with strong anti-radiation, anti-inflammatory, and anti-fibrosis effects. It is thus a promising drug candidate for the treatment of severe radiodermatitis.

Purpose: Graft-versus-host disease (GVHD) is a common complication after allogeneic hematopoietic stem cell transplantation (allo-HSCT). GVHD may affect several organs, including ocular manifestations, ranging from dry eye syndrome to sight-threatening corneal ulceration or perforation. Limited information is available about characteristics and treatments of ocular GVHD and its relation to general prognosis.

Plaque-type psoriasis is a chronic immune-mediated inflammatory skin disease of uncertain etiology, significantly impacting patient well-being. This chronic condition not only contributes to stigmatization and mental health challenges but also poses an independent risk for cardiovascular and other comorbid diseases. Affecting approximately 60 million people globally, psoriasis manifests primarily as mild-to-moderate disease in about 80% of cases, where topical therapy is pivotal.

The aim of this study was to evaluate the efficacy of a paraffin ointment enriched with vitamin A in the protection against severe desiccation using 2D and 3D corneal epithelial in vitro models. We used immortalized human corneal epithelial cell cultures to evaluate the efficacy of four compounds -a paraffin ointment enriched with vitamin A (vA-PFF) and its vehicle; an aqueous gel containing hydroxypropyl guar (HPG); and an aqueous gel containing sodium carboxymethylcellulose (CMC)- to preserve cell viability in an in vitro model of desiccation. WST-1 and Live/Dead assays were used to study cell viability.

Cocrystallization has emerged as a promising formulation strategy for modulating transdermal drug absorption by enhancing solubility and permeability. However, challenges related to cocrystal dissociation in the semi-solid state need to be addressed to mitigate regulatory concerns before the widespread implementation of topical cocrystal products in clinical practice. This study aimed to develop oil-based topical formulations incorporating cocrystals with distinct thermodynamic stabilities, followed by investigating the roles of different structurally similar coformers and oily vehicles on their physicochemical properties.
