Answer

Persons with cardiorespiratory symptoms include patients with increased pulmonary resistance with acetylcholine challenge, which may be a limiting factor in certain occupations (eg, those relating to aerospace).

One form of cholinergic urticaria, sometimes called cholinergic erythema, is believed to show persistent and individual macules of short duration, but with new macules continually appearing at adjacent sites.
