Latex-induced asthma in a dental assistant

In this case report, latex-induced asthma is described in a dental assistant with an associated history of contact dermatitis, contact urticaria, and rhinitis. She switched to vinyl gloves, which eliminated her cutaneous symptoms, but her respiratory symptoms continued. Skin-testing to latex was strongly positive. Methacholine challenge and peak expiratory flow rates (PEFR) were abnormal during the workweek but normalized after a two-week vacation. Nebulized latex was implicated in the development of occupational asthma, and personal latex-avoidance measures did not prevent the condition.
