Grass awn foreign bodies are a common cause of rhinitis in dogs. Early detection and complete removal of these foreign bodies are important for minimizing risks of long term complications. The objective of this retrospective, descriptive cross-sectional study was to determine whether discriminating CT findings exist between dogs with grass awn foreign body rhinitis and dogs with non-foreign body rhinitis. Computed tomography scans of 47 dogs with a confirmed diagnosis of non-foreign body rhinitis (25 cases) or of a nasal grass awn foreign body (22 cases) were reviewed. In the latter group, grass seeds were visualized directly on CT images for one of 22 (5%) cases. Focal lysis was more strongly associated with the presence of a grass awn foreign body (P = .012, LR = 3.0) and widespread lysis (involving more than one-third of the nasal cavity and/or bilateral) appeared associated with non-foreign body rhinitis (P = .046, LR = 2.0). Maxillary recess filling was associated with non-foreign body rhinitis (LR = 4.4) as was widespread lysis (LR = 2.0). Findings supported prioritizing grass awn foreign body rhinitis as a differential diagnosis for dogs with the former CT characteristics, even if a grass awn cannot be directly visualized.

To describe endoscopic findings, foreign body location, success rate of removal and complications in dogs with bronchial vegetal foreign bodies. Materials and MethOds:The current study retrospectively evaluated the case records of dogs diagnosed with bronchial vegetal foreign bodies at a veterinary hospital centre between January 2010 and April 2020. Information retrieved included breed, sex, age, bodyweight, the season of presentation, presentation and duration of clinical signs, previous removal attempts performed by the referring veterinarian, foreign body location and endoscopic and imaging findings.results: Eighty-four cases were included. Fifty-nine dogs (70%) presented during spring and summer.Cough (77 of 84; 92%) and fever (15 of 84; 18%) were the main clinical signs. One to 10 bronchial vegetal foreign bodies were removed from each dog. Purulent exudate was observed in the ventral larynx, trachea and bronchi in 49 (65%), 61 (81%) and 71 (95%) dogs, respectively. In most cases, only the barbules of the vegetal foreign bodies were initially observed during endoscopy. The presence of large bronchial nodules or an irregular mucosal surface was a frequent finding (62 of 75; 83%). Mild bleeding was the main complication (58 of 75; 77%) of endoscopic removal, which was successful in 67 of the 84 (80%) cases. clinical significance: Mucosal nodules associated with purulent material within the airways are frequent endoscopic findings in dogs with bronchial vegetal foreign bodies. Bronchoscopy is a relatively safe and useful technique for diagnosis and treatment of bronchial vegetal foreign bodies in dogs.

mon complications include system occlusion, urinary tract infection and sterile cystitis. In this case series, we describe three cats with subcutaneous ureteral bypass devices placed where transmural migration of subcutaneous ureteral bypass catheters into the small intestine resulted in gastrointestinal signs, urinary infection and subcutaneous ureteral bypass occlusion. The system was changed in one case and removed in the other two. In all cases, an intestinal resection and anastomosis was performed. All cats had a good medium-term outcome, and urinary infection persisted in the case for which the subcutaneous ureteral bypass system was changed. Transmural migration of the device should be considered in cats with subcutaneous ureteral bypass presenting with persistent urinary tract infection, gastrointestinal signs or device obstruction, even if imaging studies such as ultrasound or contrast studies do not demonstrate any abnormalities.
