Background: Anesthesia and surgery may influence toddlers' sensory processing and consequently postoperative adjustment and behavior. This is the first study to: 1) test pre- to postoperative changes in sensory processing after pediatric anesthesia using the validated Infant/Toddler-Sensory Profile for 7-36 months (ITSP7-36); 2) identify putative predictors of these changes.

Methods: This prospective cohort study included 70 healthy boys (ASA I & II), aged 18-30 months, who underwent circumcision for religious reasons.

This systematic review and meta-analysis was conducted to evaluate the safety of gelatin versus hydroxyethyl starches (HES) and crystalloids when used for cardiopulmonary bypass (CPB)-priming in cardiac surgery. MEDLINE (Pubmed), Embase and CENTRAL were searched. We included only randomized, controlled trials comparing CPB-priming with gelatin with either crystalloids or HES-solutions of the newest generation.

Rapid derivatization of the common hydroxyl function may resolve this analytical problem.
