title: [Pollinosis caused by Parietaria. Clinical observations in Northern Sardinia and botanical and allergic considerations on P. officinalis L. and P. judaica L. (P. diffusa Mert. and Koch)].
abstract: Botanical and allergological relations between two Parietaria species with greater pollinosic incidence, P. officinalis and P. judaica-P. diffusa, are examined: taxonomic and morphological aspects are discussed, and a key for their determination is proposed. Results of clinical-allergological survey on pollinosic subjects in North Sardinia during several years by means of Prick or Scratch Test are now presented. Diagnostic assays have been effected with extracts found on the market while the therapy has been carried out with extracts of "allergoids" and "modified" type, as well as with extracts of P. judaica. Cross-reactivity between P. officinalis and P. judaica has been evidenced, and greater therapeutic efficacy has been observed by employing "purified" and "modified" vaccines.
