Researchers Evaluate Equine Hematology Parameters

Italian researchers believe that a wide number of “healthy” variables—such as breed and geographic location—might impact horses' blood test results. And with the current textbook reference hematology values being based on the Thoroughbred horse in the United Kingdom, the team believes it might be time to develop new reference v...

Osteochondrosis Field Evaluation Protocol Developed

It's common knowledge that osteochondrosis—a developmental orthopedic disease that results from a disruption in the growth of articular cartilage located in specific joints—can cause problems for young horses, but how common is it? How are different breeds affected? Where are the most common lesion sites? And, of course, what’s the m...

Therapeutic Ultrasound Settings for Horses Identified

Did you know that ultrasound can be used for more than just diagnosing tendon and ligament injuries in horses? Indeed, veterinarians can also use it therapeutically to treat soft tissue injuries, but what settings they should use and how long they should treat an injured horse has, until now, been a bit of a "guesstimation" game.

Ultrasonography to Diagnose Equine Lung Problems (AAEP 2012)

Ultrasound is a noninvasive tool veterinarians can use to diagnose myriad medical maladies, including those affecting either the lungs or the space around the lungs. Although practitioners perform thoracic ultrasound exams in referral settings routinely, they can also conduct these efficiently and effectively in an ambulatory setting, explained Virginia B...

CT for Equine Limb Fracture Diagnosis? (AAEP 2012)

A fracture can put a horse's athletic future--sometimes even his life--on the line, and basing treatment on a complete and accurate diagnosis can make a major difference in the horse's recovery. A veterinarian in Belgium believes computed tomography (CT) offers a better option for imaging some lower limb fractures than radiography.

Navicular Bone Fragments' Effect on Lameness (AAEP 2012)

Although researchers have been studying the equine navicular bone for years, many mysteries still surround it. For instance, advanced imaging techniques give veterinarians a clearer picture than ever of irregularities or damage to the navicular bone, but it's not always evident what such pathologies mean for a horse's soundness. Elizabeth Yorke, D...

MRI to Identify Bone Changes in Racehorses (AAEP 2012)

Horses can't describe brewing musculoskeletal discomfort the way human athletes can, so trainers and veterinarians don't know which horses to put on the proverbial bench to prevent career- or even life-ending injuries. But an equine research team has been using MRI to detect bone changes that could indicate a horse is at risk for catastrophic fetl...

Decoding Small Intestine Problems with Ultrasound (AAEP 2012)

The sooner a veterinarian is able to determine whether a colicking horse requires surgery, the better the horse's chances of survival. Colic originating in the small intestine can be particularly tricky since it is not always easily felt on rectal palpation. Ultrasound examination, commonly used in general equine practices for diagnosing pregnancies a...

Hoof Radiographs' Role In Practical Farriery (AAEP 2012)

Radiographs are an often overlooked but indispensible tool for assessing a horse's feet and developing a hoof care plan that will maximize his soundness. At a recent in-depth seminar titled "The Foot from Every Angle," Randy Eggleston, DVM, of the University of Georgia's School of Veterinary Medicine, described how to optimize use of rad...

Identifying Laminitic Changes with MRI

Magnetic resonance imaging (MRI) might offer evidence of laminitic changes in a horse's hoof before the disease is otherwise identified. Equine radiologist and consultant Alexia McKnight, DVM, Dipl. ACVR, of McKnight Insight, in Chadds Ford, Pa., shared her anecdotal experience identifying laminitic changes via MRI during her presentation "Equine...

Top Equine Surgery Studies of 2012 (AAEP 2012)

Equine practitioners are undeniably busy individuals, making farm calls, caring for patients, and evaluating test results on a daily basis. To help veterinarians keep up to date on the most recent and relevant research, three veterinarians review the top studies in the fields of surgery, medicine, and reproduction at the annual American Association of Equ...

Digital Radiographs Beat Analog for Enterolith Detection

Veterinarians have known for many years that analog radiography is an efficient means of diagnosing enteroliths in adult horses, but computed, or digital, radiography has since replaced many analog machines. Researchers at the University of California, Davis (UC Davis) recently put the newer technology to the test and found it outperformed its predecessor...

Study: Nanoparticles to Deliver Therapy for Heaves in Horses

Scientists at Ludwig Maximilians University’s Department of Veterinary Medicine in Munich, Germany, are applying nanoscale molecule research in human allergy suppression to horses. In a recent study the team designed and administered a nanoparticleto deliver CpG-ODN (an immunostimulating DNA that has been shown to suppress allergies in humans) to ho...
