Does pain severity predict stone characteristics or outcomes in emergency department patients with acute renal colic?

Objectives: After initial emergency department (ED) management of acute renal colic, recurrent or ongoing severe pain is the usual pathway to ED revisits, hospitalizations and rescue interventions. If index visit pain severity is associated with stone size or with subsequent failure of conservative management, then it might be useful in identifying patients who would benefit from early definitive imaging or intervention. Our objectives were to determine whether pain severity correlates with stone size, and to evaluate its utility in predicting important outcomes.

Increasing the mobility of EEG data collection using a Latte Panda computer.

Background: Electroencephalography (EEG) experiments often require several computers to ensure accurate stimulus presentation and data collection. However, this requirement can make it more difficult to perform such experiments in mobile settings within, or outside, the laboratory.

New Method: Computer miniaturisation and increasing processing power allow for EEG experiments to become more portable.
