Abstract:
Atopic dermatitis (AD) is a chronic, relapsing inflammatory skin disease driven by immune dysregulation and skin barrier defects. This article summarizes the impact of climate change on AD outcomes, focusing on articles published since April 2023. Climate change amplifies environmental stressors, temperature extremes, altered humidity, and rising air pollution, that can trigger or worsen AD symptoms by increasing oxidative stress, disrupting the skin's microbiome, and weakening barrier function. Studies suggest associations between climate variables and AD outcomes, although findings are inconsistent. Strategies such as patient education, indoor air filtration, and broader policy measures to reduce pollution may mitigate climate-related risks.

Asthma: Pathogenesis and Management
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.
Asthma-II: Pathophysiology and Classification
Additionally, environmental and genetic factors play crucial roles in determining an individual's susceptibility to asthma and the severity of their condition.
Critical processes in asthma pathophysiology include:
