SimulConsult is a diagnostic decision support system started by Dr.Michael Segal. It covers 1,800 diseases that have at least one neurological finding in them.
SimulConsult has an interesting logic behind it. Roughly speaking, its knowledge is derived from a ‘computational wiki’ that is restricted to physician users only. So its database is not only open for viewing, but users can submit modifications to the database. The system performs bayesian pattern matching and also considers temporal information like the age of onset and disappearance of each finding for each disease under consideration.
According to Dr.Segal, there are about 33,000 data points (disease findings) in the system and the future expansion plans are to include more of metabolism and genetic diseases. Interestingly, the wiki approach for knowledge gathering in healthcare is becoming more common (AskDrWiki, WikiDoc, wikiMD to note a few- more on them later).

Curbside.MD is a search engine for finding evidence based clinical information. The idea is to type in the search need as a natural language question that a clinician would normally ask his/her colleague, and get relevant answers from the literature (articles, images, guidelines, etc.)
I took it for a test drive with a moderately complex question (’what is the indication for platelet transfusion in an 80 year old female with dengue fever?’) and got relevant results in terms of review articles and clinical trial outcomes. Pretty cool.
The logic behind Curbside.MD is semantic indexing using a controlled medical terminology (they call it “semantic fingerprinting“) with a bit natural language processing. They provide a bunch of tools (search box, news, spellchecker etc.) for partners and a browser search toolbar for users. The technology is also available as an API service from an alternate website called Fingerprint.MD.
Praxeon is the company that started Curbside.MD and MyDailyApple in 2006. Both websites are currently free for users, but the company admits to a future ad-based business model.
