Acetone may also cause an allergic airborne contact dermatitis (ABCD), presenting a generalized skin reaction [12]. Although a substantial amount of spray-on fabric diluent evaporates before it reaches the surface, factors such as distance from spray point, diameter of spray nozzle, amount of ...
The pivotal different factor in ACD is the involvement of “allergen-specific” T cells as initiators of the inflammatory skin reaction. In irritant contact dermatitis (ICD), the inflammatory reaction mainly depends on either or both chemical and physical irritation. The most frequent chemical irrita...
By contrast, ACD is a delayed type IV hypersensitivity reaction resulting from the activation of allergen-specific T cells [18]. ACD occurs in the dermis and epidermis, where specific T cells are activated by hapten and an inflammatory cascade is triggered [18]. In light of the knowledge from...
To overcome this limitation, we have adopted a novel “allergic asthma” concept, which could represent partially the severity of an allergic reaction.17,28 Second, despite the sufficient amount of pediatric data (number of COVID-19–confirmed patients = 611), the association between pediatric ...
The exposure was SARS-CoV-2 infection, which was defined if the participants tested positive for COVID-19 either by real-time reverse transcriptase polymerase chain reaction or rapid antigen testing of nasopharyngeal swabs. We considered the original SARS-CoV-2 if the initial infection was before ...

Allergic contact dermatitis is a frequent condition with a life-long prevalence of approximately 15%. It is due to an inadequate delayed immune reaction to a normally nontoxic exogenous substance, usually a small molecule, to which the sensitized individual reacts with skin inflammation. This is re...
