Summary of results and conclusions Upon the basis of the samples considered here viagra professional 50mg on-line erectile dysfunction education, it is possible to ob- serve that cheap viagra professional 100mg with amex erectile dysfunction doctors rochester ny, from the viewpoint of quantity generic viagra professional 50mg on-line erectile dysfunction protocol ingredients, the presence of English lan- guage information is scarce, with eleven out of 15 websites containing just a few texts of any kind in English. It is particularly unexpected that even the populous areas surrounding Milan do not seem eager to reach out to potentially international users/patients. Moreover, tackling multilingual communication must be a quite recent necessity; 7 This was changed, with limits, by the recent 2802 sentence by the Italian Supreme Court of 7 February 2014, which allowed a woman who had given up her new-born child for adoption to change her mind past the legal terms. On the qualitative side, the most relevant feature is that there are very few original texts, since most are (likely to be) L1 (Italian) into L2 (English) translations. The analysed translations, including those presented in the case studies in this chapter, are mostly low-quality linguistic products, suffering from numerous syntactic calques and incongruities, as well as unsuitable lexical choices at both the non- specialised and specialised levels, which, all combined, may some- times prevent understanding and result in non-communication. The use of translation is in itself problematic, if only for the time and money a professional (L2 into L1) job requires, two factors of some relevance when discussing web (which means fast) communication, and a public service (funded by public money). On the one hand, it means that the focus of any linguistic qualitative evaluation moves from language assessment to translation quality assessment, which requires an altogether different methodological approach (House 1977/1997; Grego 2010). In this particular case, the quality of the translations was oftentimes such as to prevent full com- prehension of medical procedures as urgent as abortion, for example. It is agreed that access to healthcare information is a right for everybody, irrespective of the language spoken, and as such it should be as inclusive as possible. The ethical aspect of whether some specific information is provided in one language and not in another (especially when this is given in the country’s main language ‒ Italian, in this case) is thus evident, pointing to questions such as: who chooses what to say what in what language(s)?
