Buster's Achievements

  1. There are several great places to donate depending what your focus is. I donate to two groups: pandasppn.org and pandasnetwork.org. Pandasppn.org focuses on sponsoring clinical research and research grants associated with pans/pandas - it's more focused on medical professionals. Pandasnetwork.org sponsors research, research symposiums, and provides parent support services and outreach. Buster
  2. According to dr Swedo, The cell line that had the d8/17 marker died out. It appeared promising but no longer practical.
  3. That's a good point. The current FAQ is very PANDAS specific rather than being PANS/PANDAS and PITANDS partitioned. I'll try a version partitioned and see.
  4. Hi folks, I've been going through the various papers and trying to tease out what questions the researchers are actually answering. If you've been reading papers you think are signfiicant can you add to this list or send me a message regarding other questions/papers? I'm not looking for "review" articles, but rather people running experiments that are testing certain hypothesies. Whether sudden onset OCD is correlated with untreated strep infections? [swedo1997] S Swedo et al, "Identification of Children With Pediatric Autoimmune Neuropsychiatric Disorders Associated With Streptococcal Infections by a Marker Associated With Rheumatic Fever", Am J Psychiatry 154:1, January 1997 http://ajp.psychiatryonline.org/cgi/reprint/154/1/110.pdf [swedo1998] Swedo SE et al., "Pediatric Autoimmune Neuropsychiatric Disorders Associated With Streptococcal Infections: Clinical Description of the First 50 Cases", Am J Psychiatry 155:2, February 1998. http://ajp.psychiatryonline.org/cgi/reprint/155/2/264 Whether established OCD and/or tic disorders have exacerbations associated with treated strep infections?

  5. Will do. I'll update that section.
  6. Just a note that I updated the Frequently Asked Questions (FAQ) at http://www.latitudes.org/forums/index.php?showtopic=6266 I'll make another pass at it tomorrow to bring in more of the research of the last 2 years. Buster
  7. Hi, Leckman is an extremely reasonable doctor and has seen now first hand the PANDAS kids. He didn't retract his prior papers (which is a shame, but has said publically that he didn't think he had PANDAS kids in his prior trials and instead had kids with Tourettes who met most (if not all) the PANDAS criteria as interpreted at the time). He frankly thought sudden onset or episodic course was a throw away line as it applied to any tic because they all have sudden onset and wax/wane. It took him seeing a PANDAS kid before, during, and after an exacerbation to understand how different the sawtooth pattern of exacerbation was from the more wave like transitions associated with tics/traditional OCD. Buster
  8. Here's a reference to the original work. Heard about it today on NPR: Lancet article
  9. What is the role of Th17 in GABHS inflammation

    1. Buster


      Very important paper by Wang and Cleary on GABHS colonization inducing Th17 response http://www.pnas.org/content/107/13/5937.short
