Floppy Iris Risk Factors
We read with great interest the article by Chatziralli and Sergentanis entitled, “Risk Factors for Intraoperative Floppy Iris Syndrome: a Meta-analysis.” The authors found a hierarchy concerning α1-blockers in floppy iris syndrome (IFIS) occurrence, with tamsulosin having a 40-fold greater than the other compounds of the same family, i.e., alfuzosin, doxazosin, and terazosin. In addition, regarding the collateral factors, they concluded that “ . . . hypertension, but not diabetes mellitus, emerged as a risk factor for IFIS.” Consequently, a question arises: what is the weight of the therapy and that of the disease; in other words, is the disease per se, (hypertension) that leads to IFIS, or rather, is the therapy responsible for its occurrence?

Brain Imaging in Behavioral Neuroscience
series:Current Topics in Behavioral NeurosciencesThis volume highlights the remarkable new developments in brain imaging, including those that apply magnetic resonance imaging (MRI) and Positron Emission Tomography (PET), that allow us to non invasively study the living human brain in health and in disease.  These technological advances have allowed us to obtain new and powerful insights into the structure and function of the healthy brain ...
