title: [The prevalence of skin and mucosal symptoms in gardeners handling Ficus benjamina (weeping fig) and Hedera helix (ivy). A cross-sectional study].
abstract: BACKGROUND
  Allergic and toxic initiative symptoms from skin, eyes and respiratory tract are well known among gardeners This study reports the prevalence of these symptoms among gardeners working with Ficus Benjamina (Fb) and Hedera helix (Hh).
  
  
  METHODS
  A questionnaire concerning allergic/toxic-irritative symptoms from skin, eyes and respiratory tract were forwarded to 57 gardeners. A total of 49 questionnaires were returned and matched on sex and age with a control group. A number of 46 women and 52 men participated, with a mean age of 39 (SD 9.7). Differences in frequencies of symptoms were expressed as odds ratio (OR) with a security level of 95% after conditioned logistic regression; other results were calculated from Mantel-Haenzel test.
  
  
  RESULTS
  There were more complaints among gardeners compared to the control group f as to symptoms of asthmatic bronchitis (OR 4.6 [0.98-21.2]), rhino conjunctivitis (OR 6.4 [2.1-20.2]) and skin symptoms (OR 4.3 [1.5-12.5]). The symptoms were especially profound among the caretakers of Fb and Hh and to a lesser degree among gardeners working in greenhouses growing Fb and Hh. The symptoms of the gardeners were to a higher degree independent of the season (OR 3.1 [1.1-9]), related to working environment (OR 16.1 [3.3-78.9]) and indoor work (OR 24 [4.8-118.7]).
  
  
  CONCLUSIONS
  This study seems to demonstrate high frequencies of apparently allergic and/or toxic irritative symptoms among gardeners and should be followed by a study including clinical examinations. With knowledge of the allergenic and toxic irritative properties of Fb and Hh it seems problematic that these plants are found in such high numbers in public and private places. Allergic testing including these plants should be performed to a higher degree than is actually the case.
