Tubulotrabecular adenocarcinoma of the nasopharynx operated by transoral and transpalatal approach in a cat.

Case Summary: A 10-year-old castrated male crossbreed Birman cat was presented for respiratory difficulties, nasal discharge, dysphagia and wheezing. An obstructive nasopharyngeal mass invading the caudoventral nasal cavity and the left sphenoid sinus was observed on a CT scan. Surgical treatment via a ventral rhinotomy and curettage was performed.

Penile amputation and scrotal urethrostomy followed by chemotherapy in a dog with penile hemangiosarcoma.

A 7 yr old castrated male standard poodle weighing 25 kg was presented with a 5 day history of hematuria, dysuria, and the presence of a 2.5 cm, firm swelling within the prepuce. Abdominal radiographs revealed a soft-tissue mass on the distal prepuce and lysis of the cranial margin of the os penis.

Pelvic limb kinetic and kinematic analysis in Labrador Retrievers predisposed or at a low risk for cranial cruciate ligament disease.

Objective: To compare kinematics, net moments, powers, ground and joint reaction forces (GRF, JRF) across the hock, stifle and hip joints in Labrador Retrievers at low risk or predisposed to cranial cruciate ligament disease (CCLD).

Study Design: Cross-sectional clinical study.

Animals: Clinically normal Labradors predisposed (n = 11) or at low risk for CCLD (n = 9).

Kinetic and kinematic analysis of the right hind limb during trotting on a treadmill in Labrador Retrievers presumed predisposed or not predisposed to cranial cruciate ligament disease.

Objective: To identify gait characteristics during trotting on a treadmill in nonlame Labrador Retrievers presumed predisposed or not predisposed to cranial cruciate ligament disease (CCLD).

Animals: Clinically normal Labrador Retrievers presumed predisposed (n = 10) or not predisposed (7) to CCLD.

Procedures: The right hind limb of each dog was classified by use of a predictive score equation that combined tibial plateau angle and femoral anteversion angle as presumed predisposed (high score [> -1.

Improving regions of deviation gait symmetry analysis with pointwise T tests.

The regions of deviation method has been proposed as a technique for identifying regions of the gait cycle where joint motion deviates from normal (Shorter et al., 2008). The original statistical analysis distinguished only peak values during stance and swing.

Septic peritonitis: treatment and prognosis.

Septic peritonitis is an inflammatory condition of the peritoneum that has a wide variety of clinical courses. The etiology and pathophysiology of this condition and its diagnosis in small animals are reviewed in a companion article. This article addresses the treatment of septic peritonitis and prognosis in small animals.

Septic peritonitis: etiology, pathophysiology, and diagnosis.

Septic peritonitis is an inflammatory condition of the peritoneum that occurs secondary to microbial contamination. This clinically important condition has a wide variety of clinical courses as well as high morbidity and mortality due to secondary multiorgan dysfunction. This article reviews the etiology and pathophysiology of this condition and its diagnosis in small animals; a companion article addresses treatment and prognosis.

Segmental jejunal entrapment, volvulus, and strangulation secondary to intra-abdominal adhesions in a dog.

A 4 yr old, castrated male dachshund was presented for lethargy, restlessness, a "hunched" posture, and a painful abdomen. A gastric foreign body had been surgically removed 24 mo previously. Exploratory celiotomy revealed a devitalized segment of jejunum with twisted mesentery.

Multivariate analysis of morphometric characteristics to evaluate risk factors for cranial cruciate ligament deficiency in Labrador retrievers.

Objectives: To determine the combination of conformation characteristics of the pelvic limbs of Labrador Retrievers that best discriminates between limb at risk to develop cranial cruciate ligament (CCL) disease and limbs at low risk using radiographs, computerized tomography (CT) images, and dual-energy X-ray absorptiometry (DEXA).

Study Design: Cross-sectional clinical study.

Animals: Twelve clinically normal and 9 unilaterally CCL-deficient Labrador Retrievers.

Inverse dynamics analysis of the pelvic limbs in Labrador Retrievers with and without cranial cruciate ligament disease.

Objectives: To quantify net joint moments, joint powers, and joint reaction forces (JRF) across the hock, stifle, and hip joints in Labrador Retrievers with and without cranial cruciate ligament (CCL) disease. To investigate differences in joint mechanics between normal, CCL deficient, and contralateral pelvic limbs.

Study Design: Cross-sectional clinical study.

Evaluation of intra- and interobserver variability and repeatability of tibial plateau angle measurements with digital radiography using a novel digital radiographic program.

Objective: To compare the intra- and interobserver variability occurring when observers with differing experience levels measure tibial plateau angles (TPAs) with a novel digital radiographic projection program (tibial plateau leveling osteotomy [TPLO] planning program), the Kodak Picture Archiving and Communications System (PACS), and standard sized printed films (SF).

Study Design: Cross-sectional study.

Sample Population: Dogs (n=36) with cranial cruciate ligament (CCL) rupture that had a TPLO.

Noninvasive determination of body segment parameters of the hind limb in Labrador Retrievers with and without cranial cruciate ligament disease.

Objective: To determine mass, center of mass (COM), and moment of inertia (ie, body segment parameters [BSPs]) of hind limb segments by use of a noninvasive method based on computerized tomography (CT) in Labrador Retrievers with and without cranial cruciate ligament (CCL) disease and to provide regression equations to estimate BSPs of normal, CCL-deficient, and contralateral hind limbs.

Animals: 14 clinically normal and 10 CCL-deficient Labrador Retrievers.

Procedures: Bone, muscle, and fat areas were identified via CT.
