A new assay, Pharmacia CAP System (PCS), for allergen-specific IgE (sIgE) was evaluated in 198 new patients presenting with respiratory symptoms to an urban allergy practice. An experienced allergist examined each patient and clinically assessed sensitivity to timothy, short ragweed, Alternaria tenuis, cat, or D. farinae. Puncture and selected(More)
BACKGROUND Controlled exposure studies suggest that asthmatics may be more sensitive to the respiratory effects of acidic aerosols than individuals without asthma. This study investigates whether acidic aerosols and other air pollutants are associated with respiratory symptoms in free-living asthmatics. METHODS Daily concentrations of hydrogen ion (H+),(More)
We present three case reports involving patients with vocal cord dysfunction. The onset of symptoms in one case was coincident with a generalized cutaneous reaction to penicillin with laryngeal involvement. The other cases had been misdiagnosed as food allergy and chemical sensitivity. We describe the psychologic factors in these cases in terms of the(More)
OBJECTIVE Urban air samples contain numerous irregular respirable black particles, which may be airborne tire fragments. A major component of tires is natural latex. Proteins of natural latex can act as adjuvants and as antigens capable of eliciting immediate hypersensitivity, making their presence in particulate air pollution an important clinical issue.(More)
A new formulation of mometasone furoate (MF) for administration by dry powder inhaler (DPI) was evaluated for the treatment of asthma. A 12-week, double-blind, placebo-controlled dose-ranging study compared the efficacy and safety of three doses of MF DPI (100, 200 and 400 mcg b.i.d) with beclomethasone dipropionate (BDP) 168 mcg b.i.d. administered by(More)
A 21-year-old white male developed life threatening systemic anaphylaxis within seconds of ingesting a small amount of a cookie containing piñon nuts. Skin testing, ELISA, and basophil histamine release studies demonstrated piñon nut-specific IgE. Electrophoresis of the piñon nut extract demonstrated 30 bands, three of which (in the 66 to 68,000 dalton(More)
OBJECTIVE This study explored the safety and efficacy of cetirizine for treatment of allergic rhinitis and asthma. METHODS Daily treatment for 6 weeks with cetirizine 10 mg (93 patients) was compared with placebo treatment (93 patients) in a randomized, double-blind parallel study of patients with allergic rhinitis and asthma. This multicenter study was(More)
Although there is abundant clinical evidence of asthmatic responses to indoor aeroallergens, the symptomatic impacts of other common indoor air pollutants from gas stoves, fireplaces, and environmental tobacco smoke have been less well characterized. These combustion sources produce a complex mixture of pollutants, many of which are respiratory irritants.(More)
