Age at onset of clinical abnormalities, duration of clinical abnormalities prior to surgery, and preoperative neurologic status are risk factors for success of surgical management of AAS in dogs.

Objective—To evaluate the effect of cold compression therapy (CCT) on postoperative pain, lameness, range of motion of the stifle joint, and swelling following tibial plateau leveling osteotomy (TPLO) in dogs. Design—Randomized, blinded, placebo-controlled clinical trial. Animals—34 client-owned dogs with unilateral deficiency of a cranial cruciate ligament undergoing TPLO. Procedures—Dogs were assigned to 2 groups. Group 1 (n = 17 dogs) received CCT in the 24-hour period following TPLO. Group 2 (n = 17 dogs) received no CCT. Degree of lameness, range of motion, and circumference of the stifle joint were measured before surgery and 1,14, and 28 days after surgery. A modified composite Glasgow pain scale, visual analogue scale, and pain threshold score were used to evaluate signs of pain before surgery and 1,14, and 28 days after surgery. Logistic regression and linear regression analysis were used to compare the measured variables. Results—No complications were observed, and all dogs tolerated CCT. Use of CCT resulted in lower values for the visual analogue scale and Glasgow pain scale and lower pain threshold scores; lower lameness scores; less swelling; and an increased range of motion 24 hours after surgery. At 14 days after surgery, there were no significant differences between groups. At 28 days after surgery, too few data sets were available for comparison. Conclusions and Clinical Relevance—CCT decreased signs of pain, swelling, and lameness and increased stifle joint range of motion in dogs during the first 24 hours after TPLO.

Results suggested that LPS was common in dogs with naturally occurring CCL rupture. However, only minor clinical, radiographic, cytologic, and histologic differences were identified between dogs with and without LPS.

TPLO may neutralize tibial thrust by modifying PTA as well as decreasing TPA. TPLO to a TPA of 6 degrees may not be necessary to neutralize the cranial tibial thrust according to the plateau rotation based on PTA(CT) measurement.

This report describes a primary clitoral adenocarcinoma in a dog with secondary hypercalcemia of malignancy. A 10-year-old, spayed female basset hound was evaluated for a mass protruding from the vulva. The mass was excised, and a histological diagnosis of clitoral adenocarcinoma was made. No evidence of metastasis on thoracic radiographs or abdominal ultrasound was seen. Preoperative hypercalcemia resolved following excision of the mass. Cellular features were similar to an apocrine gland anal sac adenocarcinoma, and immunohistochemistry exhibited features noted with apocrine gland anal sac adenocarcinoma. No further treatment was elected by the owner. Internal iliac lymph-node metastasis was identified 4 weeks postoperatively, and hypercalcemia recurred 8 weeks postoperatively. The dog was euthanized 22 weeks postoperatively for signs related to hypercalcemia, including polyuria/polydipsia, lethargy, and weakness. A necropsy was performed and confirmed the presence of internal iliac lymph-node metastasis. The colon, rectum, and anal sacs were grossly and histologically normal. To our knowledge, this is the first reported case of clitoral neoplasia in the dog.
