Procedures were categorized by species (small animal, equine, food animal) and disciplines (imaging, anesthesia, diagnostic medicine/necropsy). Ophthalmology was added as a fourth discipline for the class of 2010. Students recorded procedures into the ...
Differentiation of ataxic and orthopedic gait abnormalities in the horse. The differentiation of ataxia and orthopedic disease can be facilitated by the use of several additional tests, not commonly part of either neurologic or orthopedic examination protocols. However, a full neurologic and orthopedic examination and suitable diagnostic imaging will of course also be necessary in such cases. The common association of orthopedic and neurologic disease makes it even more necessary to correctly attribute movement or posture abnormalities to potentially treatable structures.
Plasma therapy in foals and adult horses. Although a range of plasma-based products (e.g., cryoprecipitate, albumin, platelet-rich plasma, individual coagulation factors) are available to human physicians, equine veterinarians are largely restricted to using whole blood, frozen plasma, and fresh frozen plasma for transfusions. The indications for frozen or fresh frozen plasma in human medicine are relatively limited, and there is little evidence supporting the efficacy of these products in many cases. Furthermore, many human physicians have concerns regarding disease transmission and anaphylactic reactions after administration of any ...
Generalised tetanus in a 2-week-old foal: use of physiotherapy to aid recovery. A 2-week-old Estonian Draft foal presented with signs of severe generalised tetanus, recumbency and inability to drink. The suspected source of infection was the umbilicus. Medical treatment was administered, including tetanus antitoxin, antimicrobial therapy and phenobarbital to control tetanic spasms. In addition, an intensive physiotherapy program was carried out during the recovery period. Techniques designed for syndromes involving upper motor neuron spasticity in humans were applied.

Understanding abdominal ultrasonography in horses: which way is up? The recent introduction of more affordable and portable ultrasound equipment makes it possible to perform transabdominal ultrasonography on equine patients in the field. Clipping the hair is not always necessary: intraabdominal structures can be quickly evaluated by soaking hair with isopropyl alcohol and using a 3.0- to 3.5-MHz curvilinear transducer. The ultrasonographer must be acquainted with the location and architecture of normal intraabdominal structures and simultaneously mindful of the depth of the viewing field, the tissue interface densities, the orientation of the transducer relati...
Neonatal encephalopathy in foals. Neonatal encephalopathy is a common central nervous system disorder of neonatal foals and human infants, resulting in clinical signs such as lethargy, inappropriate behavior, seizures, and other neurologic deficits. Although neonatal encephalopathy is frequently seen in equine practice, a paucity of veterinary clinical and basic science research data is available. Therefore, the pathophysiologic mechanisms of this disorder in equids, such as energy deprivation, excess excitatory amino acids, and free radical injury, have been extrapolated from human medicine. Equine veterinarians have used var...
