Sigmoid colon penetration by an intrauterine device: a case report and literature review.

Background: The intrauterine device (IUD) is one of the most effective contraceptive methods available today. However, IUDs can cause some serious complications, such as bleeding, uterine perforation, and bowel perforation. Migration into bowel is a rare but serious complication that requires surgical attention.

Reduction of conscious sedation requirements by olfactory stimulation: a prospective randomized single-blinded trial.

Objectives: This study investigated the possibility that olfactory stimulation would decrease sedation needed for colonoscopy and therefore decrease the recovery time needed after conscious sedation.

Materials And Methods: Patients were randomized to receive a cherry-flavoredscent in oxygen flowing at a 4 L per minute rate via nasal cannula or oxygen alone. The scent was provided in a cherry-flavored oil.
