Teratoma is a rare germ cell testicular cancer composed of cells that are not normally present in the site where it originates. These tumors are rarely described in horses, where they may develop due to cryptorchidism. Teratomas consist of cells originating from different germinal layers, arising from germinal multi-potential cells with differentiation defects, and can simultaneously contain several tissues from two or more embryonic layers. Testicular teratomas are described in horses, cats, dogs, wild boars, bulls, and humans. In the rare descriptions found in literature of testicular teratoma in stallions, they occur frequently in cryptorchid testicles, as a consequence of congenital neoplasm. To our knowledge there is no other report of a dentigerous equine teratoma in a stallion. We describe here a successful laparoscopic removal of a testicular teratoma and its clinic-pathological features.

This study evaluated the effect of different dietary concentrations of Goji berries (GB) on the meat quality of rabbit. At weaning, 60 New Zealand male rabbits were assigned to three groups and fed with a commercial standard diet (C), C supplemented with 1% (LG) or 3% Goji berries (HG) until slaughter. Supplementation did not affect colour, water holding capacity, and tenderness but regression analyses showed linear relationships between pH (P < .05), Thiobarbituric Acid Reactive Substances (TBARS; P < .001), Oxygen Radical Absorbance Capacity (ORAC; P < .001), Redox Index (RI; P < .001), and phenolic content (P < .001) of Longissimus thoracis et lumborum muscle and the rate of GB in the feed. However, by pairwise comparisons emerged that acidification (pH: P < .05), antioxidant/oxidant status (TBARS, ORAC, RI; P < .001), and phenolic content (P < .01) of muscle significantly improved only in HG compared with C group. Then, a dose-dependent relation was found but only the higher dose of GB guaranteed an increase in protection against oxidative phenomena of meat., (Copyright © 2019 Elsevier Ltd.

Objectives: Oral pain is underrecognized and undertreated in small animal practice. This study aimed to develop and perform a preliminary validation of an instrument to evaluate oral and maxillofacial pain in dogs and cats. Methods: Indicators potentially associated with oral pain in dogs and cats were identified and selected. The Composite Oral Pain Scale-Canine/Feline (COPS-C/F) in the Italian language was developed using a two-part questionnaire (owner and veterinary specific questionnaires). The instrument was used to score the intensity of oral and maxillofacial pain in patients with oral disease. Content validity was performed and the COPS-C/F was applied to 20 dogs and 16 cats with oral disease at baseline and 15 days after dental treatment for construct validity. Criterion validity was assessed by comparing the COPS-C/F with a visual analog scale (VAS), a numeric rating scale (NRS), and a simple descriptive scale (SDS). Construct validity/responsiveness and criterion validity were assessed with Wilcoxon and Spearman Pearson tests, respectively ( p ≤ 0.05). The Cronbach's alpha coefficient was used to calculate internal consistency. Thereafter, the instrument was refined and translated to English and back-translated for semantic equivalence. Results: Construct validity was confirmed with a significant reduction of pain scores after treatment ( p < 0.05) for most items. Criterion validity was confirmed by a significant correlation among the COPS-C/F total pain scores and those from VAS, NRS, and SDS ( p < 0.05). Cronbach's alpha coefficient was 0.876 and 0.860 for the owner and the veterinary specific questionnaires, respectively, indicating good internal consistency. The items that did not present significant differences between time-points and the VAS, NRS, and SDS were removed prior to translation to English (COPS-C/F ENG). Conclusions and Clinical Relevance: The study described the development and preliminary validation of the COPS-C/F as an instrument for pain assessment in dogs and cats. Refinement and back-translation of COPS-C/F with semantic equivalency resulted in the COPS-C/F ENG consisting of six and four items for the owner and veterinary specific questionnaires, respectively. The English version requires further validation and testing using a larger number of patients in the clinical setting.

Objectives: To describe the perioperative management, including surgery, anesthesia, metabolic derangements, and physiotherapy, in a goat referred for paraparesis secondary to a road traffic accident., Study Design: Case report., Animals: 2-year-old mixed breed dwarf 44 kg female pet goat., Methods: Clinical examination showed symptoms of early compensatory stages of shock, paraparesis with hyperextension of the thoracic limbs, pain on palpation of the thoracolumbar spine, increased patellar reflexes of both pelvic limbs without superficial sensitivity, but preserved deep pain sensation. These signs suggested a spinal cord injury with upper motor neuron syndrome and an anatomic localization between the third thoracic and third lumbar vertebrae. Radiographic examination revealed a thoracolumbar vertebral subluxation. Vertebral stabilization was achieved with the application of pins in the vertebral bodies stabilized by an interconnecting bridge of polymethylmethacrylate, a technique commonly adopted in companion animals., Results: Surgery and recovery from anesthesia were uneventful, but 3 days later ruminal atony and subsequent bloating occurred. This was associated with metabolic derangements (metabolic alkalosis), decreased mentation, and marked tachypnea that responded to medical treatment. From day 3 post-surgery, the goat underwent physiotherapy with manual and active exercises during the rehabilitation period of 21 days duration., Conclusion: The injury in this goat was successfully managed using vertebral stabilization similar to that used in dogs and cats. Extensive postoperative physiotherapeutic support contributed to the complete recovery of the animal., (© 2016 The American College of Veterinary Surgeons.)
