title: Environment and sensitization to cypress in Israel.
abstract: Cypresses are part of the Israeli landscape, as well as they are over most of the Mediterranian area. Pollen dispersal starts in January and peaks in March-April. Assessment of hay-fever patients showed a prevalence of 24%-32% (depending on the region) sensitization to Cypress (Cupressus sempervirens) pollen extracts. 13% of all those who are sensitive to Cypress were monosensitized. They are symptomatic from February till April, when 70% of them have rhinitis, 30% also asthma and 18% conjunctivitis. In the monosensitized patients, anti-cypress immunotherapy was successful.
