Bean bag allergy revisited: a case of allergy to inhaled soybean dust.

Background: Soybean is a common food allergen. It can cause Type 1 allergy (IgE-mediated) symptoms from its ingestion, as well as from inhalation of its dust.

Objective: To report a case of allergy in a child from the inhalation of soybean dust from a bean bag and the course of this allergy over time.

Occupational asthma secondary to inhalation of garlic dust.

An atopic patient in whom the inhalation of occupationally encountered garlic dust precipitated asthma is reported. Studies revealed the presence of immediate skin-test reactivity to garlic extract, and specific IgE anti-garlic antibodies were detected in the patient's serum by the polystyrene tube solid phase radioimmunoassay (PTRIA) technique. Bronchial challenge with garlic dust also resulted in an immediate asthmatic response typical for an IgE-induced mechanism.
