שאלה מ 21/7 שלא נענתה

Dear Professor Zadik, is there a non-public e-mail address or a phone number I can use to contact you? You have not answered my question dated 21 July and I am really eager to read your opinion. I turned to you at the recommendation of Prof. Arnold Pollak, Director of the Paediatric Dept. of the Vienna Gereal Hospital. Many thanks in advance!
