For a long time, SM were thought to be restricted to rural areas; however, they can also be found in urban dwellings. Given that SM exhibit minimal cross-reactivity with HDM and among different SM species, these mite species should be diagnosed and treated separately. To date, there is no overview of which mite species occur in which areas of Germany. The aim of this study was therefore to investigate the indoor acarofauna in Germany, especially allergologically relevant HDM and SM.</p><h3>Methods</h3><p>Between 2006 and 2009, 2554 dust samples were collected from volunteers in all German federal states at different times of the year.

Due to the increasing life expectancy, rising multimorbidity, and growing polypharmacy, there is an increase not only in incidence, but also in diagnostic and therapeutic complexity. Cutaneous adverse drug reactions (CADRs) are highly relevant from a clinical and health economic perspective and require differentiated, guideline-based management.</p><h3>Objective</h3><p>The aim of this study is to provide a comprehensive overview of the pathophysiological mechanisms, clinical manifestations, and current diagnostic and therapeutic strategies for cutaneous drug reactions.</p><h3>Results</h3><p>Analyses of the current literature show that early and differentiated diagnosis is essential for the effective treatment of cutaneous drug reactions.

Consequent topical basic therapy and avoidance of potential trigger factor is recommended for all patients. Basic therapy should be applied not only during a flare, but also to clear skin to prevent worsening; furthermore, mild/moderate eczema should receive anti-inflammatory therapy with topical corticosteroids/calcineurin inhibitors.

Systemic therapies are grouped into conventional and targeted therapies (biologics and Janus kinase inhibitors). Systemic corticosteroids should only be used as rescue therapy for 3 weeks maximum. Targeted therapies in AD have the highest recommendation grade for long-term therapy.
