title: [Type I hypersensitivity to pollen of the Poaceae family (Gramineae), by tribe, in atopic dermatitis patients].
abstract: Type I Hypersensitivity to Poaceae pollen was tested in 27 Costa Rican patients with a clinical diagnosis of Atopic Dermatitis (six were males). Skin prick tests were done with 1/10 W/V, 50% glycerinated, pollen extracts, organized by tribes. Most patients had several allergic problems. Sensitivity increased with the number of allergic diagnoses. Positivity ranged from 25% in patients with Atopic Dermatitis exclusively to 100% in those with three or four simultaneous allergic illnesses. Andropogoneae was highest with 37% while the lower positivity was in the Paniceae (22.2%).
