Medstory is a health information search engine that went into a public beta in mid 2006. In feb 2007, it was acquired by Microsoft. Their interface is pretty minimalistic, with only a search keyword box on the homepage. The results returned with an option to refine it in various categories like conditions, procedures, trials, articles etc. The google-like interaction and navigation reduces the noise that is usually associated with health related information search.
There isn’t much out there that explains the technology behind Medstory (except vague references to machine learning and AI, like in this CNET article). Anyway, it’s yet another addition to Microsoft Health Solution Group’s product portfolio that includes the enterprise health information system Amalga and the consumer-oriented Healthvault platform.

With a play on google’s name, MEDgle offers symptom based health information search. The idea is to ‘empower patients in their discussions with physicians’, by making relevant content easy to find.
The navigation is pretty simple and straightforward. MEDgle’s output is a probabilistic list of disease/conditions based on the user input. The content is authored by their 3-physician team and is based on publicly available information available such as the Center for Disease Control and National Institutes of Health. Where probability estimates were not available, they have used their own practice experience to fill in the gaps.
The need for a healthcare vertical search engine is widely realized, and like everything else, it opens up the ability for potential (ab)use with self-diagnosing hypochondriacs. Skepticism aside, I did a search using a common symptom (difficulty in walking, heel pain) and found it easy to navigate to a list of links and information around bone spur and plantar fasciitis. The “Related Local Doctors” section for finding local providers relevant for your symptoms is a neat idea too.
There is an obvious limit to the utility of such tools- Alexia Estabrook’s blogpost talks about MEDgle’s performance for a more complex query. Although that points to the Achilles heel of any diagnostic decision support system today; it’s hard to model the entire spectrum of disease-symptom relationship in an all-inclusive, 100% accurate way. It has more to do with the ever-expanding body of medical knowledge than the lack of technical prowess. That why medicine is a science and an art.
PS: You can read the interviews of some of MEDgle team members here and here.

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.
