Re Reply #13 : When you see the word, "Guest," under a poster's name as with "Beautyqueen," it means that the person is no longer a member here, by choice or otherwise. They may read the replies, but cannot post. Thus, she will not be replying. It has been several years since she was "active." Check Replies # 7 and 11 on this thread. I believe they will answer your question/s, as the respondents are QUITE knowledgeable on this Forum. If I remember correctly, Doctor Eugene/Yevgeny S. Botkin had problems with a renal calculus/calculi, which can be VERY painful. AP.
