Morales Yñiguez FJ, Leise BS.Over 25% of all emergencies are classified as wounds, making them the most common health conditions treated by veterinarians. While equine wounds may heal with minimal intervention, many complications associated with wound management can occur, thereby delaying wound healing and leading to chronic non-healing wounds. Wounds should be closed primarily when possible; however, numerous factors influence the risk of complications. Infection and biofilm production are common causes of delayed wound healing. Other causes of non-healing wounds include the presence of foreign material, sequestrum form...
Fain H, Hendrickson DA, Buesing MT, Griffenhagen G.Cryptorchidism is a common congenital disorder in male horses characterized by the failure of one or both testes to descend into the scrotum.

García-López JM.Intrathecal and intrasynovial tendon and ligament injuries can result in extrusion of tendon/ligament fibers, granuloma, and adhesion formation that not only impairs healing of the original injury but can create new injuries that negatively affect adequate healing and return to athletic work. In these cases, endoscopic evaluation and debridement, not only of the lesion, but also any other secondary injury present, can enhance the healing of the tendon or ligament and improve the athletic prognosis. Careful planning of the approach, positioning, instrumentation, and thorough knowledge of the an...
Bethel M.EPM remains particularly rampant in racing populations due to transport stress, young age, and congregate housing conditions. For compounding pharmacists, understanding that we're managing chronic parasite suppression - not achieving cure - fundamentally changes our approach to formulation strategy, stability assessment, and client counseling. The two formulations presented separately represent years of refinement, demonstrating compounding's essential role when commercial products fall short.

Hinckley-Boltax AL, Malone E, Uustalu UK, FitzMaurice M.The Association of American Veterinary Medical Colleges competency-based veterinary education (CBVE) framework can be used to guide curriculum and assessment design and is intended to prepare veterinary graduates for Day One of clinical practice. However, while the framework defines curricular outcomes in terms of demonstrable competencies, it does not define the specific knowledge, skills, and attitudes required to achieve those outcomes. In some human medical curricula, prioritized lists of clinical presentations guide curricular content, design, and assessment. These lists are based, in par...
Lizarraga I, Castillo-Alcala F.Donkeys have contributed to the development and livelihoods of humans for almost 7,000 years. They have been used for traction and transportation, kept as pets, utilized in animal-assisted therapies, or farmed as food-producing animals. Over the past two decades, significant progress has been made in bridging the knowledge gap in veterinary medicine between donkeys and horses. Veterinary practitioners are now more aware that donkeys have important behavioral, anatomical, and physiological characteristics that distinguish them from horses. These peculiarities should be considered when treating ...
Asai Y, Tsunetoshi Y, Susa Y, Matsuzawa A, Miyazaki S, Itagaki Y, Yamamoto H, Kimura K, Kushiya H, Sato S, Okada N, Yamabuki T, Kato K, Kinoshita Y....Horse kicks are a rare cause of injury and tend to cause severe complications such as visceral organ injury. Traumatic duodenal injuries are associated with high mortality rates. Furthermore, their reconstructive procedures vary widely and require appropriate on-the-spot judgment by the surgeon. We experienced a case of blunt abdominal trauma with a complete transection of the first portion of the duodenum caused by a horse kick without any associated lesions. A good postoperative course was achieved by trimming the pyloric part of the stomach and performing an end-to-end anastomosis between t...
Hellige M, Geburek F.A number of indications exist that necessitate radiologic examination of the equine cervical spine. Different neurologic and pain-associated clinical signs within the scope of lameness or poor performance may be associated to pathologies of the cervical spine. Moreover, the number of requests for radiographic examinations of the cervical spine, for example as part of the pre-purchase examination, has increased significantly in recent years. However, the interpretation of radiographs represents a challenge, particularly in the case of clinically sound horses, as it often necessitates the resolu...
