Bilateral ureteral obstruction in a cat due to a ureteral transitional cell carcinoma.

A 15-year-old cat was presented with a history of lethargy and vomiting. Serum biochemistry revealed severe azotemia. Ultrasonography revealed a small left kidney and hydronephrosis of the right kidney.

Chondroma of the vertical ramus of the feline mandible.

A 5-year-old, castrated male, domestic shorthair cat presented with firm swelling in the right temporal region of the skull. The cat's jaws were almost locked in the closed position. Radiographs showed a mass with an irregular mineralized matrix superimposed on the caudal right mandible and temporomandibular joint.

Urethral obstruction in cats: predisposing factors, clinical, clinicopathological characteristics and prognosis.

Feline lower urinary tract diseases in general, and urethral obstruction (UO) in particular, are common clinical conditions in cats. The aims of this study were to identify risk factors for UO, to characterise clinical and clinicopathological signs, outcome and recurrence, as well as risk factors for mortality and recurrence. Eighty-two cats with UO were compared to 82 sex and time matched controls.

Oesophageal sarcomas in dogs: histological and clinical evaluation.

A histological grading system of oesophageal sarcomas has not been established. Thirty-two cases of oesophageal sarcomas have been reviewed for tumour characteristics and clinical outcome. Nineteen dogs underwent surgical intervention to remove oesophageal tumours; ten of them survived (median 278 days).

Chemotherapeutic treatment of xenograft Spirocerca lupi-associated sarcoma in a murine model.

To date, data are not available concerning the effectiveness of chemotherapy in the treatment of Spirocerca lupi-associated esophageal sarcomas. In the present study, we compared the effectiveness of 4 chemotherapeutic agents against S. lupi-associated osteosarcoma, using a xenograft murine model created in our lab.

Evaluation of lidocaine treatment and risk factors for death associated with gastric dilatation and volvulus in dogs: 112 cases (1997-2005).

Objective: To determine clinical features, outcome, risk factors for death, and efficacy of IV administration of lidocaine as a prophylactic treatment for ischemic reperfusion injury in gastric dilatation and volvulus (GDV) in dogs.

Design: Retrospective case series.

Animals: 112 dogs with GDV.

Perineal urethrostomy in a brown capuchin monkey (Cebus apella).

A 14-yr-old male brown capuchin monkey (Cebus apella) was presented to the Veterinary Teaching Hospital of the Hebrew University of Jerusalem, Israel, with stranguria. The history included distal urethral obstruction and a previous surgical attempt to create a urinary diversion through the perineum. A perineal urethrostomy was performed.

Murine xenograft model of Spirocerca lupi-associated sarcoma.

Nodular masses and granulomas of the esophagus are among the most frequent lesions caused by Spirocerca lupi, a nematode parasite of dogs, and neoplastic transformation of these granulomas to osteosarcoma or fibrosarcoma has been described. In this study, we developed a xenograft murine model of S. lupi-associated sarcoma.

Expression of relaxin receptor LRG7, canine relaxin, and relaxin-like factor in the pelvic diaphragm musculature of dogs with and without perineal hernia.

Objectives: To compare the expression of canine relaxin, relaxin-like factor (RLF), and relaxin receptors within the muscles of the pelvic diaphragm of dogs with perineal hernia (PH) and clinically normal dogs.

Study Design: In vivo comparative study.

Animals: Fifteen client-owned intact male dogs with PH were studied.

Partial esophagectomy with single layer closure for treatment of esophageal sarcomas in 6 dogs.

Objective: To report partial esophagectomy (PE) as a treatment for esophageal sarcoma in dogs.

Study Design: Retrospective study (2000-2002).

Animals: Six dogs with caudal thoracic esophageal tumors.

Spirocercosis-associated esophageal sarcomas in dogs. A retrospective study of 17 cases (1997-2003).

Seventeen client-owned dogs diagnosed with spirocercosis-associated esophageal sarcomas were retrospectively reviewed. The most common clinical signs noticed were vomiting and/or regurgitation (94%), lethargy and depression (59%), pyrexia and anorexia (41% each). Leukocytosis (82%) and microcytic hypochromic anemia (30%) were the most common hematological abnormalities.
