Zahra, I do feel that there is value for attendees to some of the presentations. For myself, these would hold little value (frankly, I could give many of these presentations myself), but for most people they do have some value, and you will get a chance to see some very good doctors speak and may get the chance to ask questions of them. I've sat in on patient and parent programs before and they don't teach me much and sometimes create frustration for me, due the parochial views of many of the people involved. However, there are things that can be learned about dealing with day to day life of thals, basic ideas about treatment, such as managing combination chelation and what regular tests should be done, that do have value. If I was there, I would go (mostly to interact with patients, parents and doctors).
