EPM Testing
Equine protozoal myeloencephalitis (EPM) is a frustrating disease. It's been referred to as one of the most overdiagnosed, underdiagnosed and misdiagnosed equine diseases - an apt description. In some areas, every horse (particularly every racehorse) that has any real or perceived abnormality (such as not running fast enough) gets treated, usually without any attempt to make a true diagnosis. Most of these animals don't have EPM, but some might, along with horses displaying a range of sometimes vague neurological signs. When an effort is made to really establish a diagnosis, unfortunately it's not straightforward, which leads to more confusion about the disease and how to manage it.
The Animal Health Diagnostic Center at Cornell University have released a document on EPM testing and diagnosis. This document discusses when and why to test, along with important information about the available, recommended tests. It's a nice, comprehensive overview of the subject and worth a look for equine veterinarians as well as horse owners wondering whether their horse may have this enigmatic disease.

Comparison of the Accuracy of Radiography and Ultrasonography for Detection of Articular Lesions in Horses
Objective
To compare the accuracy of ultrasonographic and radiographic examination for evaluation of articular lesions in horses.
Study Design
Cross-sectional study.
Animals
Horses (n = 137) with articular lesions.
Methods
Radiographic and ultrasonographic examinations of the affected joint(s) were performed before diagnostic or therapeutic arthroscopic surgery. Findings were recorded and compared to lesions identified during arthroscopy.
Results
In 254 joints, 432 lesions were identified by arthroscopy. The overall accuracy was 82.9% for ultrasonography and 62.2% for radiography (P < .0001) with a sensitivity of 91.4% for ultrasonography and 66.7% for radiography (P < .0001). The difference in specificity was not statistically significant (P = .2628). The negative predictive value for ultrasonography was 31.5% and 13.2% for radiography (P = .0022), the difference for the positive predictive value was not statistically significant (P = .3898). The accuracy for ultrasonography and radiography for left versus right joints was equal and corresponded with the overall results.
Conclusions
Ultrasonographic evaluation of articular lesions was more accurate than radiographic evaluation.
Animal Chiropractic Care
Chiropractors view the spine as the fundamental aspect of overall health. Since the spine houses the nervous system, any abnormality of the spine affects the entire body. Therefore, the nervous system is the governor of the body, and a chiropractor’s goal is to maintain proper spinal alignment. In general, chiropractic is a drug-free approach to pet health care. A few terms associated with chiropractic are vertebral subluxation, homeostasis, adjustment, and innate intelligence. A subluxation is defined as a joint that does not properly move compared to other adjacent joints. Therefore, a subluxation is a misalignment or joint dysfunction. This is not only confined to the spine, but the majority of the subluxations are vertebral subluxations. Homeostasis is defined as an internal stability and equilibrium of an organism. This is achieved by adapting or eliminating an environmental stimulus. Chiropractic helps the body’s internal balance or homeostatic state since adjustments eliminate any hindrance on nerve function. An adjustment is a short lever, high velocity controlled thrust by the hand that is directed at specific articulations to correct subluxations. The purpose of an adjustment is to realign the joints so that normal movement can occur and eliminate nerve interference. This eliminates any pain or discomfort and allows for proper neurologic function to ensue. Innate intelligence is the body’s ability to heal itself. Chiropractic care removes any hindrance to this natural process and allows the body’s healing process to occur. Additionally, innate intelligence of the body encompasses the body’s natural ability to adapt to changes in its internal and external environments in order to maintain a state of health. In order for proper chiropractic care of your pet, a history and examination are required. The examination includes posture analysis, gait analysis, vertebral and extremity static palpation, vertebral and extremity motion palpation, orthopedic evaluation and neurological evaluation. The examination takes place upon your pet’s entrance into the clinic. Observing the animal’s demeanor and ambulation into and out of the office is vital in the examination. Even though you might only see the motion and static palpation, the examination starts as soon as you walk through the door!
