Periorbital emphysema after dive barotrauma without radiological evidence of paranasal sinus injury.

Background: Scuba diving has increased in popularity since its invention in 1943, with over 21 million PADI registered members worldwide. Injuries to the paranasal sinuses caused by barotrauma are the second most common after injury to the middle ear.

Case Report: In this paper we present a case of unilateral periorbital surgical emphysema in a 23-yr-old male commercial scuba diver with minimal symptoms following an uneventful 13-ft (4-m) dive.

Tramadol for pain relief in children undergoing tonsillectomy: a comparison with morphine.

Background: Pain control for paediatric patients undergoing tonsillectomy remains problematic. Tramadol is reported to be an effective analgesic and to have a side-effect profile similar to morphine, but is currently not licensed for paediatric use in the UK.

Methods: We conducted a prospective, double-blind, randomized controlled trial in children who were scheduled for elective tonsillectomy or adenotonsillectomy at the Royal Aberdeen Children Hospital.
