Pediatric external auditory canal foreign bodies: a review of 698 cases.

Objective: The study goal was to determine the relationships between patient management factors and patient outcomes in pediatric patients with external auditory canal foreign bodies.

Study Design And Setting: Retrospective analysis was conducted of 698 consecutive cases of pediatric external auditory canal foreign bodies (n = 605 patients) who presented to a tertiary care pediatric referral center during a 6-year period.

Results: Emergency physicians frequently removed foreign bodies under direct visualization while otolaryngologists primarily used otomicroscopy.

Coronary stent and over-the-wire catheter exchange using standard length guidewires: Jet exchange (JEX) practice and theory.

The practice and theoretical principles of hydraulic exchange of over-the-wire (OTW) stent and PTCA catheters are described. Seventy-eight Palmaz-Schatz coronary stent delivery systems (PS-SDS), 8 Cook Flex-stents, and 247 assorted OTW catheters were delivered and extracted over standard length coronary guidewires using Jet Exchange (JEX). JEX was performed by pressurizing the wire lumen of coronary stent catheters to 18-20 atm and PTCA catheters to 15 atm.
