All skin diseases have an underlying immune component. Owing to differences in animal and human immunology, the majority of drugs fail in the preclinical or clinical testing phases. Therefore animal alternative methods that incorporate human immunology into in vitro skin disease models are required to move the field forward. This review summarizes the progress, using examples from fibrosis, autoimmune diseases, psoriasis, cancer and contact allergy. The emphasis is on co-cultures and 3D organotypic models. Our conclusion is that current models are inadequate and future developments with immune-competent skin-on-chip models based on induced pluripotent stem cells could provide a next generation of skin models for drug discovery and testing.

Evaluating the ingress of total polycyclic aromatic hydrocarbons (PAHs) specifically naphthalene through firefighter hoods and base layers.

Structural firefighters are exposed to an array of polycyclic aromatic hydrocarbons (PAHs) as a result of incomplete combustion of both synthetic and natural materials. PAHs are found in both the particulate and vapor phases in the firefighting environment and are significantly associated with acute and chronic diseases, including cancer. Using a fireground exposure simulator (FES) and standing mannequins dressed in four different firefighter personal protective equipment (PPE) conditions, each with varying levels of protective hood interface and particulate-blocking features, the efficacy of the hoods was assessed against the ingress of PAHs (specifically, naphthalene).

Obesity is associated with several other comorbidities, including psoriasis, which is a chronic autoimmune skin disease. Adipocytes produce pro-inflammatory signaling molecules, namely adipokines and classic cytokines, that drive increased inflammation axnd may contribute to the pro-inflammatory pathways driving psoriasis disease pathogenesis.

Post-acne scarring can pose a significant psychosocial burden on patients of all ages; therefore, treatment approaches must be both rapid-acting and effective. Microneedling is a minimally invasive technology that involves the creation of controlled tissue microinjury and subsequent induction of collagen production and tissue remodeling.

Background: Social media is used as a tool for information exchange, entertainment, education, and intervention. Intervention efforts attempt to engage users in skin health.
Objective: This review aimed to collect and summarize research assessing the impact of social media on skin health promotion activities undertaken by social media users.
Background: Ruxolitinib cream has demonstrated anti-inflammatory and antipruritic activity and was well tolerated in a phase 3 study in patients aged 2-11 years with mild to moderate atopic dermatitis (AD).
Objective: This study examined the safety, tolerability, pharmacokinetics, efficacy, and quality of life (QoL) with ruxolitinib cream under maximum-use conditions and with longer-term use.
Methods: Eligible patients were aged 2-11 years with moderate to severe AD [Investigator's Global Assessment (IGA) score 3-4], and ≥ 35% affected body surface area (BSA).
