Passive drainage versus primary closure after total ear canal ablation-lateral bulla osteotomy in dogs: 59 dogs (1985-1995).

Objective: Compare passive wound drainage to primary closure of total ear canal ablation-lateral bulla osteotomy (TECA-LBO) in dogs.

Study Design: Retrospective analysis of medical records.

Sample Population: Fifty-nine dogs with end-stage otitis externa or neoplasia of the external and middle ear.

Adenomatous polyps and carcinoma in situ of the canine colon and rectum: 34 cases (1982-1994).

The medical records of 34 dogs (median age, eight years) with colorectal mucosal lesions were reviewed. Hematochezia was the most common (82%) presenting sign. Most dogs (79%) presented with solitary masses located in the rectum.

Globule leukocyte tumor involving the small intestine in a cat.

Globule leukocyte tumor involving the distal portion of the jejunum and proximal portion of the ileum caused chronic vomiting and weight loss in a 3-year-old cat. The intestinal mass was resected during exploratory laparotomy. The histologic appearance of the mass was characterized by inclusion of numerous intracytoplasmic eosinophilic granules.

Mechanical evaluation of half-pin (type 1) external skeletal fixation in combination with a single intramedullary pin.

Half-pin (type 1) external skeletal fixators with four, three, and two fixation pins and an intramedullary pin, and four-pin external skeletal fixators without an intramedullary pin were applied to prepared canine femurs. Load to failure, load to yield, safe load, and stiffness under compressive and torsional loads were calculated. When tested in compression, all measurements for the four-pin fixators with an intramedullary pin were significantly higher than for the two-pin fixators with an intramedullary pin.
