Thymic carcinosarcoma with melanocytic differentiation in a dog.

Carcinosarcomas are very rare tumors in dogs. Although carcinosarcomas with melanocytic differentiation arising from organs other than the thymus have been described in humans, this type of tumor has not been reported in dogs in any part of the body. We observed such a tumor in the cranial mediastinum of an 11-year-old spayed female dachshund.

The Successful Use of an Ultrasound-Guided Mid-Femur Sciatic Nerve Block in a Juvenile Emu () under General Anaesthesia.

The current case report describes a successful ultrasound-guided mid-femur sciatic nerve block in an emu. A 2-month-old emu suffering from acute-onset lameness was referred to the University Clinic of Liège, where he was diagnosed with a lateral luxation of the Achilles tendon on both hind limbs. Two surgical procedures were performed for treatment.

Effect of the surface geometry of uncemented acetabular cups on primary stability in a model of uncemented total hip replacement in dogs.

Objective: To compare the in vitro stability of acetabular cups with peripherally reinforced fixation in a model of uncemented total hip replacement in dogs.

Sample: 63 polyurethane foam blocks and 3 acetabular implant designs: hemiellipsoidal (Model A) and 2 models with equatorial peripheral fins (Model B with 1 level and Model C with 2 levels of fins).

Methods: 2 loading patterns-edge loading and push-out tests-were performed until failure and peak forces were recorded.

Comparison of hydroalcoholic rubbing and conventional chlorhexidine scrubbing for aseptic skin preparation in dogs.

Objective: To compare preparation time, ease of application, and elimination of skin contamination of 3 skin preparation methods for asepsis.

Study Design: Experimental study.

Animals: Healthy dogs (n = 6) with no clinical signs of skin disease.

Prefrontal cortical activity associated with visual stimulus categorization in non-human primates measured with near-infrared spectroscopy.

In biomedical research of brain dysfunction in psychiatric disorders, utilization of animal models is essential. However, translation of findings in animal models into the realm of human clinical conditions requires reliable biomarkers that are assessed with the methods mutually employed in animal models and human patients. Near-infrared spectroscopy (NIRS) is a functional neuroimaging technique that has now been widely utilized in human basic and clinical research.
