Think twice while inserting a transannular patch

Better think before agreeing twice

Think twice before you tell

Answer to the Rhythm Puzzle At first glance the ECG looks very abnormal. The P-wave morphology is not compatible with sinus rhythm, the conduction intervals are normal, and the QRS complexes are very abnormal in amplitude (micro-voltages in the extremity leads). In lead II there is almost no signal at all. Althoughmicro-voltages in the extremity leads are a common feature in one of the most pre...

Vertebroplasty for osteoporotic fracture? Think twice.

Think twice before recommending vertebroplasty (VP) for symptomatic osteoporotic compression fractures. New studies suggest that it has little benefit; thus, VP should be considered only after other, more conservative options fail.

Use of a pulmonary neovalve with a transannular patch for repair of tetralogy of fallot.

INTRODUCTION AND OBJECTIVES To report on our initial experience with the implantation of a pulmonary valve using Nunn's technique in association with a transannular patch for the complete repair of the tetralogy of Fallot. METHODS In total, 21 patients were treated between September 2008 and February 2010. Their ages ranged from 7 months to 15 years (median 12 months) and weights from 6.8 kg ...

Think twice and then: combining or choosing in dialectical bootstrapping?

Individuals can partly recreate the "wisdom of crowds" within their own minds by combining nonredundant estimates they themselves have generated. Herzog and Hertwig (2009) showed that this accuracy gain could be boosted by urging people to actively think differently when generating a 2nd estimate ("dialectical bootstrapping"). Although the "crowd within" promises accuracy gains, it remains uncl...
