Two beef cows were presented with a history of anorexia and abdominal pain. Both cows were euthanized. Necropsy revealed the presence of a segmental area of ulceration, necrosis, and intraluminal blood clots in the jejunum. Jejunal hemorrhage syndrome is an emerging disease and has not been reported previously in beef cattle.
The medical records of equine gastrointestinal colic cases presented to the Western College of Veterinary Medicine between 1992 and 2002 are reviewed. There was no breed predisposition to colic. Geldings were more prone to colic than females and stallions. Overall, the 3 most common causes of colic were large colon impaction (20.8%), large colon(More)
OBJECTIVE To describe and evaluate an endoscope-guided balloon sinuplasty technique for dilation of the equine nasomaxillary opening (NMO). STUDY DESIGN Experimental study. ANIMALS Equine cadaver heads (n=5); Quarter Horses (n=4). METHODS A custom rigid balloon introducer was passed into position within the NMO at the caudal recess of the middle(More)
OBJECTIVE To investigate the relationship between inflammatory responses of the temporomandibular joint (TMJ) and the metacarpophalangeal (MCP) joint in clinically normal horses. ANIMALS 7 mature horses. PROCEDURES In each horse, 1 TMJ and 1 MCP joint were injected with lipopolysaccharide (LPS; 0.0025 μg). The contralateral TMJ and MCP joint were(More)
OBJECTIVES To determine the frequency of postoperative septic arthritis after elective arthroscopy in the absence of prophylactic antimicrobial therapy and to report complication rate of 444 consecutive equine arthroscopies. DESIGN Retrospective case series. ANIMALS Horses (n = 444). METHODS Medical records of 444 consecutive elective equine(More)
OBJECTIVE To evaluate an alternative surgical method for treating periapical infection of the mandibular cheek teeth of horses. DESIGN Retrospective study. ANIMALS Eleven horses (3-13 years) with periapical mandibular tooth infection. METHODS Hospital records (1992-2002) of horses that had periapical curettage for the treatment of mandibular cheek(More)
Disease of the paranasal sinuses of the horse is common and treatment often involves lavage and sometimes surgery. The development of minimally-invasive, sinus-specific treatments, such as balloon sinuplasty, requires a thorough understanding of this complex anatomical region. To improve this understanding, 10 heads from dead horses of various ages were(More)
OBJECTIVE To investigate potential relationships between cheek tooth occlusal morphology, apparent feed digestibility, and the reduction in feed particle size that occurs during digestion in horses. DESIGN Cross-sectional study. ANIMALS 17 horses of various ages and breeds and either sex. PROCEDURES Horses were fed 1 of 3 hay-based diets ad libitum(More)
OBJECTIVE To determine whether occlusal angle of the premolar and molar teeth (ie, molar occlusal angle) was associated with feed digestibility, water balance, or fecal particle size in adult horses. DESIGN Observational study. ANIMALS 40 pregnant mares ranging from 3 to 19 years old. PROCEDURE The horses were randomly allocated to 1 of 5 feeding(More)
OBJECTIVES To report the occurrence of, and risk factors associated with, incisional complications of equine ventral median celiotomies closed with USP 7 polydioxanone (7PD). STUDY DESIGN Retrospective case series. SAMPLE POPULATION Horses (n = 73; 75 celiotomies). METHODS Medical records (2000-2010) were retrieved and reviewed for horses that had a(More)
