I've just tried six different medical searches and I'm not seeing Scholar articles. Maybe it's a test - but if so, it is also a test I would probably appreciate seeing. In many "scholarly" searches there is too much junk to wade through these days.
If you want Scholar articles why aren't you searching within scholar.google.com?
I recently discovered while looking up something else that in some countries, "scholar" is one of the visible items in g###'s Black Bar. For the less brainy parts of the world, you have to look under More to bring it up ;)
Anyway, this interlocks beautifully with JSTOR's recent decision to allow complete access to their older articles (exact cutoff age depends on which country you're in). No more getting chopped off in the middle of an abstract dating from 1871.
What country are you in? When I check googles that I've never used in my life, the content of the top bar varies by country. Fascinatingly, Norway, Denmark and Greenland have "scholar" in plain sight but in Sweden it's relegated to "more"-- where it's at the top of the list. google.uk similarly has "scholar" as the first item on the "more" list; google vanilla has it much further down.
