Diagnostic evaluation of urea nitrogen/creatinine ratio in dogs with gastrointestinal bleeding.

Background: Urea nitrogen/creatinine ratio (UCR) is a marker for upper gastrointestinal bleeding (GIB) in people.

Objectives: To assess the usefulness of UCR to predict occult GIB and distinguish upper from lower GIB in dogs.

Animals: Eighty-nine dogs with GIB and 65 clinically healthy dogs.

A pilot study on the effect of fat loading on the gastrointestinal tract of healthy dogs.

Objective: To assess the effect of a high fat meal (fat loading) on gastrointestinal motility and the appearance of intestinal villi using video capsule endoscopy and ultrasound.

Materials And Methods: Four healthy staff-owned dogs were included in a prospective blinded crossover study. Dogs had initial baseline video capsule endoscopy to measure gastrointestinal transit times and allow for visual assessment of intestinal mucosa.

A wireless endoscopy capsule suitable for imaging of the equine stomach and small intestine.

Background: Capsule endoscopy offers a new method for visualization of the gastrointestinal mucosa in horses where other imaging technologies have diagnostic limitations.

Objectives: To (1) test the feasibility of using this novel endoscopy capsule to visualize intestinal mucosa in horses, including an objective assessment of image quality, (2) assess how changes in preadministration preparation affect the transit time and the amount of gastrointestinal mucosa visualized, and (3) describe intestinal mucosa lesions in healthy horses.

Animals: Five healthy adult horses.

Repeated rhinoscopic and serologic assessment of the effectiveness of intranasally administered clotrimazole for the treatment of nasal aspergillosis in dogs.

Objective: To determine the role of rhinoscopic evaluation and repeated serologic testing in assessing the success rate of intranasally administered clotrimazole for treatment of dogs with nasal aspergillosis.

Design: Prospective case series.

Animals: 23 dogs with nasal aspergillosis.
