I am still researching and writing up a monster post on membraous nephropathy and pregnancy (2,300 words and 7 images so far and I still have a handful of references to go). Researching this topic is like archeology. All the literature is from the early 90's and 80's. Almost none of the data is available as full text on the web. No PDFs. Its all scans of photocopies.
But I think the topic is important and having and the fact that the primary data is locked up in paper makes a comprehensive review indexible by google, all the more important.
The survey is also gaining data. So far it is showing definite equipoise on the questions. I am still looking for some more participants.
