Comparative histomorphometric analysis of cellular phenotype in canine stifle ligaments and tendon.

Objective: To measure the density of cellular phenotypes in canine caudal cruciate ligament (CaCL), cranial cruciate ligament (CrCL), medial collateral ligament (MCL), and long digital extensor tendon (LDET).

Study Design: Ex-vivo study.

Methods: Ten CaCL, CrCL, MCL, and LDET obtained from 1 stifle of 10 dogs with no gross pathology were analyzed histologically.

Detection of bacterial DNA by PCR in dogs with stifle pathology.

Objective: To determine presence of bacterial DNA in canine stifles with cranial cruciate ligament rupture (CCLR) and medial patellar luxation (MPL) compared to normal canine stifles (control).

Study Design: Prospective clinical study.

Animals: Dogs (n = 44).

Histomorphometric analysis and regional variations of full thickness skin grafts in dogs.

Objective: To (1) compare thickness of the epidermis and dermis of anatomically different donor sites in dogs, and (2) evaluate hair follicle damage during full thickness skin grafts (FTSG) preparation from anatomically different donor sites. Another objective was to compare the extent of agreement between gross and histologic quality of graft preparation.

Study Design: Ex vivo study.

Outcome after repair of a sarcoma-related pathologic fracture in dogs: a Veterinary Society of Surgical Oncology Retrospective Study.

Objective: To report outcome in dogs after internal fixation of a sarcoma-related pathologic fracture of the appendicular skeleton.

Study Design: Multi-institutional case series.

Animals: Dogs (n=16).

Pathologic fracture in dogs with suspected or confirmed osteosarcoma.

Objective: To evaluate clinical presentation of pathologic fractures associated with suspected or confirmed osteosarcoma in dogs and to assess treatment and survival times.

Study Design: Case series.

Animals: Dogs (n=25) appendicular pathologic fracture.

Vascular distribution in ruptured canine cranial cruciate ligament.

Objective: To (1) determine the microanatomic vascular distribution in ruptured canine cranial cruciate ligaments (CCL) using specific vascular immunohistochemical techniques, and (2) compare vessel density between ruptured and intact canine CCL and between different areas of interest in ruptured CCL using histomorphometric analysis.

Study Design: In vitro study.

Animals: Dogs (n=41) admitted for surgical treatment of ruptured CCL and 19 dogs euthanatized for nonorthopedic conditions.

Immunohistochemical and histomorphometric evaluation of vascular distribution in intact canine cranial cruciate ligament.

Objectives: To (1) describe vascular distribution in the grossly intact canine cranial cruciate ligament (CCL) using immunohistochemical techniques specific to 2 components of blood vessels (factor VIII for endothelial cells, laminin for basement membrane); and (2) compare the vascularity in different areas of interest (craniomedial versus caudolateral bands; core versus epiligamentous regions; and proximal versus middle versus distal portions) in the intact normal canine CCL.

Study Design: In vitro study.

Animals: Large, mature dogs (n=7) of breeds prone to CCL disease that were euthanatized for nonorthopedic conditions.

Use of color flow Doppler ultrasonography to diagnose a bleeding neuroendocrine tumor in the gallbladder of a dog.

Case Description: A 13-year-old neutered female Keeshond-cross was evaluated because of a history of melena, anemia, hematemesis, vomiting, and high serum liver enzyme activities over a 1.5-year period.

Clinical Findings: Abdominal ultrasonography revealed a hyperechoic mass in the gallbladder.

Spontaneous left medial liver lobe torsion and left lateral lobe infarction in a rottweiler.

The abdominal ultrasonogram of a dog admitted for acute onset of collapse revealed an abnormally displaced left medial liver lobe with no blood flow. Surgical and histological findings confirmed the ultrasonographic diagnosis of left liver lobe torsion. Ultrasonographic findings were useful and probably sufficient for a correct diagnosis.

Tracheal rupture in a cat: diagnosis by computed tomography.

A cat was presented with a history of worsening generalized subcutaneous emphysema following dental prophylaxis. Tentative diagnosis of tracheal rupture was made. The location and extent of the tear was confirmed with the help of computed tomography.

Cecal inversion followed by ileocolic intussusception in a cat.

A cat was presented with a history of constipation, tenesmus, and malaise. Ultrasonography revealed an ileocolic intussusception and cecal inversion. Surgical findings included an easily reducible intussusception and an inverted cecum that was moderately difficult to reduce.
