Veterinary Student Self-Assessment of Basic Surgical Skills as an Experiential Learning Tool.

Mastery of basic skills is critical for surgical training. Such training is best obtained by experiential learning, which requires an element of self-reflection. Self-reflection is not always an automatic process, however; guidance may be required.

Migration of retrobulbar wooden foreign body between diagnostic imaging and surgical extraction in a German shepherd dog.

A 2-year-old, male castrated German shepherd dog was presented to the University of Tennessee Veterinary Medical Center (UTVMC) with periorbital swelling and conjunctival mucopurulent discharge 2 days following removal of a twig from the medial canthus by the owner. Diagnostic imaging was pursued due to the suspicion of a retrobulbar foreign body (FB). A cylindrical FB approximately 3.

Ammonia concentrations in canine whole blood, EDTA-anticoagulated whole blood, and plasma measured by use of a point-of-care ammonia meter.

OBJECTIVE To investigate the use of canine whole blood (WB) for measurement of ammonia concentration by use of a point-of-care ammonia meter and to compare results of measuring ammonia concentrations in WB, EDTA-anticoagulated WB, and plasma. ANIMALS 40 client-owned dogs. PROCEDURES A blood sample (2 mL) was obtained from each dog.

The effectiveness of cooling conditions on temperature of canine EDTA whole blood samples.

Background: Preanalytic factors such as time and temperature can have significant effects on laboratory test results. For example, ammonium concentration will increase 31% in blood samples stored at room temperature for 30 min before centrifugation. To reduce preanalytic error, blood samples may be placed in precooled tubes and chilled on ice or in ice water baths; however, the effectiveness of these modalities in cooling blood samples has not been formally evaluated.

Perineal Protrusion Secondary to Imperforate Hymen and Hydrocolpos in an 8-Year-Old Spayed Female Dog.

An 8-year-old female spayed Dachshund presented with an acute onset of dysuria, dyschezia, and painful perineal protrusion. A perineal hernia was ruled out on digital rectal examination, and blood work was unremarkable. An extremely dilated vagina was identified on computed tomography, and hydrocolpos was suspected.

Evaluation of a semiquantitative SNAP test for measurement of bile acids in dogs.

Background. Serum bile acids (SBA) are used as a routine screening tool of liver function in dogs. Serum samples are usually shipped to a referral laboratory for quantitative analysis with an enzymatic chemistry analyzer.

Urethral prolapse in dogs: a retrospective study.

Objective: To evaluate the signalment, clinical signs, treatment, and outcome of dogs with urethral prolapse and identify risk factors associated with prolapse or treatment.

Study Design: Retrospective case series.

Animals: Dogs (n = 48) with urethral prolapse.

Objectives of this study were to adapt a commercial human protein C (PC) colorimetric assay for use in dogs and to investigate effects of various storage conditions. The human assay was modified by using pooled canine plasma for calibration and by increasing the activation time. PC activity was measured in fresh canine plasma and in plasma stored under various conditions.

Portosystemic vascular anomalies.

Portovascular anomalies are most commonly seen as congenital communications in dogs and cats. Fixation, whether surgical or interventional, should be considered in all cases for which it is possible to improve perfusion to the liver, and ultimately liver function. Medical management before fixation is always recommended.

Laryngeal paralysis in dogs.

Laryngeal paralysis is a common cause of upper airway obstruction in older, large-breed dogs and is likely associated with a generalized polyneuropathy in most animals. Surgical therapy is frequently indicated, and UAL is currently the recommended treatment. Respiratory signs significantly improve in most patients after surgery; however, postoperative complication rates can be high, and patients have a lifelong risk of developing respiratory tract disease.

Inflammatory mammary carcinoma in 12 dogs: clinical features, cyclooxygenase-2 expression, and response to piroxicam treatment.

Canine inflammatory mammary carcinoma (IMC) is a rare, locally aggressive, highly metastatic tumor that is poorly responsive to treatment. The purposes of this study were to retrospectively evaluate the history, signalment, and clinical signs of dogs with IMC; compare the outcome of affected dogs treated with traditional chemotherapy with those treated with piroxicam; evaluate Cox-2 expression of IMC cells; and correlate Cox-2 expression with outcome based on treatment. Strong cyclooxygenase-2 expression was present in all tumors.

Head and neck swelling due to a circumferential cicatricial scar in a dog.

A 4-year-old, castrated male, mixed-breed dog was evaluated because of progressive head swelling, exercise intolerance, and increasing respiratory effort of 1 month's duration. Physical examination and radiographs revealed severe edema of the head and face that was cranial to a circumferential, midcervical constriction caused by scarring related to previous removal of a foreign body. Surgical en bloc resection of the cicatricial tissue was performed, and clinical signs resolved completely after 2 months.
