It's again that time of the week: the latest issues of Medical Blogging Grand Rounds and Tangled Bank are up at The Grunt Doc and The Grey Thumb Blog, respectively.

From The Grand Rounds, here are a few of the entries which might also be of interest to you:

• The Health Business Blog's take on the economics of pharmaceutics.
• DB's Medical Rants on the pharmaceutical industry: the good, the bad, and the ugly.
• An introduction to Terra Sigillata, a new blog by an experienced pharmacologist.
• and my voted best entry to this round: Aggravated DocSurg's "The Straight Poop on anal Fissure Therapy": using nitroglycerin and botox in the treatment of chronic anal fissures.

From the Tangled Bank, some of the other entries under the Medicine section are particularly interesting:

From Aetiology comes an article explaining in detail why Malaria is so nasty. It plays hide-and-seek and changes it's molecular signature, among other dirty tricks.
Cognitive Daily has a great article about a neurological disorder called focal distonia. In the process, they go into some fascinating detail about how the brain makes use of some of the same regions when it thinks about certain activities as it does when actually performing them.
In The Pipeline discusses controversy over how animal models are used to test compounds for carcinogenic effects.
Why worry about bird flu when there are superbugs running around? James from Ruminating Dude asks why we're spending so much on bird flu (that might not materialize) when these nasties are a very real threat.

Note that Aetiology and cognitive Daily are now part of a network called ScienceBlogs, a project of Seed Media Group, the publishers of Seed Magazine.
