This is a very cool website

Endobible arranges a database of endocrine diseases in widely searchable manner. They lead physicians through the diagnosis, work-up and treatment of most endocrine diseases. They skip diabetes, but outside of that is looks awesome. Nice reminder that endocrine is more than diabetes.

I perused the Conn's Syndrome section (primary hyperaldosteronism). The history and physical were great. The work-up was less impressive. They don't advise saline loading and they still recommend stopping ACEi and beta-blockers before performing a Aldo Renin Ratio. Good luck keeping a resistant hypertension patient from stroking while you wash all those drugs out for 4 weeks.

Overall a clever design and great resource.

Online endocrine textbook

This looks pretty cool.

Here is the link to the section on kidney stones written by Murray Favus. On my brief overview it looks good.

Being in the textbook business in the era of free online textbooks, UpToDate and wiki's has got to be a world of hurt.
