One resource I would add to your list: http://www.uptodate.com/

Since few MDs can actually stay on top of the latest developments for all the different items that cross their desks, UpToDate serves as a curated summary of many medical conditions, and is updated every 6 months (? maybe 9, it's been a while) for each topic.

It is a subscription service, and if you are dealing with anything in between problematic-to-serious, it is well worth subscribing for a month. If the language is difficult in whatever article seems relevant to you, it is worth figuring out the language because it will provide a good jumping-off point to go examine the literature on which it is based (which is likely your next stop, for serious conditions.)
