Sometime this summer a wiseacre commenter (we get a few) suggested we do a "Five Apps" for a variety of somewhat offbeat topics. One wasn't so far-fetched however: gastroenterologist. One could say that a gastro doc has about the same needs as any doctor, of course, and that's an easy out. So here are 5 apps that are great for gastroenterologists and possibly any medical specialist... Coming soon: 5 apps for the lemur owner.

Epocrates Rx - This free app looks up drugs and is updated weekly. Epocrates [iTunes link] has already been available for other mobile platforms for a while, this is a must-have for physicians, I would think. There's also a Pro version that is designed for medical professionals, and it requires a yearly subscription fee to work. It's $99 for one year, which is pretty reasonable for what this does -- which includes an amazing pill ID tool.

DocWrite - Another free app with a service you subscribe to, but this may appeal to more than doctors. DocWrite [iTunes link] is a transcription service that sends your ramblings securely and sends you back a complete transcription in PDF or Word. DocWrite has a web-based dashboard for your stuff, too, so you'll never be without those documents in text or audio.

PubSearch - PubMed is a massive database of medical research papers and PubSearch (free version) [iTunes link] is an iPhone app that'll search them. Yes, of course you need a subscription to the database (noticing a trend here?). PubSearch also has a Mac desktop app, although there does not seem to be any coordination between the two. I'd imagine something like sharing bookmarks would be helpful. PubSearch Plus [iTunes link] costs $1.99 and is really the more functional version as it will show full articles and use EZProxy (where supported).

Medcalc - A free medical calculator? Yep, Medcalc [iTunes link] includes a ton of formulas for doctors, plus a few indices and charts and whatnot to keep a handy reference for those who need it. This app seems to cover a lot of ground, although I'm not sure how much applies to the field of gastroenterology.

Mobile MIM for iPhone and iPod touch - Sadly, this has yet to be released. But I'm guessing it'll be at the top of many doctors' wish lists. MIMvista makes real-deal medical imaging stuff and the MIM app for iPhone was demonstrated at WWDC. The demo was astounding, showing how doctors could merge CT and PET scans right on their iPhone and make notes for later use. The app is pending FDA approval, with no release date or price set.
