A 5-year-old castrated male English bulldog was presented for evaluation of acute vomiting and anorexia. Abdominal ultrasound revealed obstructive small intestinal foreign material with a small amount of abdominal free fluid, consistent with hemoperitoneum. Exploratory laparotomy revealed a segmental jejunal volvulus with foreign material extending from the portion of the intestines immediately orad to the volvulus into the affected intestinal loop. The dog fully recovered following resection and anastomosis of the affected small intestine. Key clinical message: This article documents the first reported case of jejunal volvulus suspected to be secondary to small intestinal foreign material. The dog was discharged 2 d postoperatively with no complications. Although reported outcomes for complete mesenteric volvulus are poor, segmental volvulus may have a better prognosis and should be considered as a differential diagnosis when small intestinal foreign material is causing obstructive ileus. The presence of hemoperitoneum may be an additional indicator that the ileus is associated with intestinal volvulus.

Objective: The objective of this retrospective study was to investigate the associations of age, sex, and breed with platelet count and function in domestic cats.

Animals: Records of healthy cats (N = 93) undergoing platelet function testing at the OVC Comparative Hemostasis Lab (Guelph, Ontario) between 2012 and 2014 were retrospectively reviewed.

Procedure: For every cat, age, sex, breed, and platelet count were recorded. Platelet function was tested using the Plateletworks (PW) ADP system (Helena Laboratories) and the Platelet Function Analyzer-200 (PFA-200) (Siemens Healthineers) with Collagen/ADP (Col/ADP) and P2Y cartridges.

Results: Platelet count was not associated with age, sex, or purebred status. The PW percent aggregation was negatively associated with age (P = 0.002; r = -0.39) but not associated with sex or purebred status; this change persisted on multivariable regression (P = 0.009). The PFA-200 closure times were not associated with age, sex, or purebred status on univariate analysis; however, on multivariate regression, there was an association between purebred status and higher Col/ADP closure times in purebred cats (P = 0.036).

Conclusion: This study revealed that feline platelet function may be associated with age and purebred status but not sex.

Clinical relevance: The degree of change was unlikely to be clinically relevant, but should be accounted for in future research studies. Platelet count was not related to signalment.

A 2-year-old castrated male Pembroke Welsh corgi dog was presented to the referring veterinarian because of acute onset of vomiting and hyporexia. Despite conservative treatment with intravenous fluids, antiemetics, antibiotics, and antioxidants, the dog rapidly deteriorated, with development of severe pigmenturia and icterus over 24 to 48 h, respectively, prompting referral. A thrombotic microangiopathy (TMA) characterized by nonimmune-mediated hemolytic anemia, thrombocytopenia, and acute kidney injury (AKI), suspected to be from hemolytic uremic syndrome not associated with known prodromal diarrhea, was diagnosed. This is a rarely described disorder in dogs and, unlike those in most previous reports, this dog survived with supportive care for AKI and a short tapering course of glucocorticoids for refractory thrombocytopenia. Steroids have been reported for managing certain TMA syndromes in humans but not in animals. The dog in this case made a full recovery, with no reported relapse over 1 y. Key clinical message: Thrombotic microangiopathy is characterized by nonimmune-mediated hemolytic anemia, thrombocytopenia, and AKI. Corticosteroids may be beneficial for treating canine TMA, based on successful recovery in this rare case of non-diarrheal hemolytic uremic syndrome.

This report describes the successful video-assisted removals of urinary bladder bullet foreign bodies in 2 cats. In both cases, the cat was presented because of chronic dysuria and hematuria. Diagnostic imaging, including radiography and ultrasonography, identified a foreign body in the bladder, confirmed as a lead pellet. Video-assisted percutaneous endoscopy was used for foreign body removal and bladder inspection. Both cats recovered uneventfully after surgery, with no postoperative complications. This report highlights the advantages of percutaneous and video-laparoscopic-assisted endoscopy in managing urinary bladder foreign bodies in small animals, providing reduced trauma and quick recovery. Key clinical message: Endoscope-assisted foreign body removal from the bladder seems to be a safe and efficient way to retrieve small foreign bodies in cats.

A 6-year-old neutered male domestic shorthair cat was presented because of a 4-week history of upper respiratory noise and suspected upper respiratory tract infection that were unresponsive to antibiotics. On physical examination, the cat had multiple cranial nerve deficits involving cranial nerves III, V, VII, and potentially VIII. Magnetic resonance imaging (MRI) of the head under general anesthesia was conducted. During the MRI, before intravenous contrast administration, the mandibular and parotid salivary glands became acutely symmetrically enlarged. Subsequent cytology of the salivary gland showed no cytological abnormalities. A condition called "anesthesia mumps" has been reported in humans, in which the salivary glands become acutely enlarged during or following general anesthesia. This is a transient swelling, and the underlying cause is unknown; however, several mechanisms have been proposed in the human literature, including physical obstruction of the salivary duct due to patient positioning, administration of anticholinergic drugs, dehydration, and other causes of salivary stasis. A suspected case of anesthesia mumps was reported in a dog following an elective neutering. This is the first reported case of anesthesia mumps in a cat. More importantly, it is the only case in which the acuteness of the swelling was captured with MRI. Key clinical message: A case of acute transient salivary gland swelling secondary to general anesthesia is described. Anesthesiologists and other veterinary professionals should be aware of this rare and benign but potentially alarming anesthesia complication.
