Diaphragmatic dysfunction in dogs with cervical spinal disorders before and after surgery using fluoroscopy, motion-mode ultrasound and radiography was not different than a group of control dogs.

Cervical spinal disorders can lead to life-threatening respiratory complications. Diaphragmatic dysfunction is attributed to spinal cord morbidity secondary to cervical myelopathy or decompressive surgical intervention. The purpose of this observational case-control study was to determine the frequency of diaphragmatic dysfunction in dogs with cervical spinal disorders and a control group, the strength of association between cervical myelopathies and decompressive surgery with diaphragm paresis, and the agreement between and clinical usefulness of fluoroscopy, motion-mode ultrasonography, and radiography for diagnosing diaphragmatic dysfunction.

Association of meniscal injury to joint space width on standard tibial plateau leveling osteotomy lateral radiographic projections of the canine stifle.

Up to 70% of dogs with cranial cruciate ligament tears have concurrent meniscal injury, and these injuries can increase the risk of developing osteoarthritis and persistent lameness. Studies assessing joint space width on knee radiographs in people have indicated associations between joint space width and meniscal injuries. The aim of this prospective analytical study was to determine if there was an association between stifle joint space width on three different radiographic projections (the standard tibial plateau leveling osteotomy projections and a standing lateral projection) and meniscal injuries identified at surgery in dogs.

Effects of short- and long-term administration of nonsteroidal anti-inflammatory drugs on osteotomy healing in dogs.

Objective: To determine the influence of short-term administration of carprofen on bone healing in dogs.

Study Design: Randomized controlled experimental study.

Animals: Eighteen purpose-bred sexually mature hound dogs.

Fin healing and regeneration in sturgeon.

Pectoral fin healing in fin spines and rays were examined in juvenile Atlantic sturgeon Acipenser oxyrinchus oxyrinchus following three different sampling techniques (n = 8-9 fish per treatment): entire leading fin spine removed, a 1-2 cm portion removed near the point of articulation, or a 1-2 cm portion removed from a secondary fin ray. Also, to determine whether antibiotic treatment influences healing, an additional group of fish (n = 8) was not given an injection of an oxytetracycline (OTC)-based antibiotic following removal of the entire leading fin spine. Following fin sampling, fish from different treatments were mixed equally between three large (4,000 I) recirculating systems and fin-ray healing and mortality were monitored over a 12 month period.

Cardiac findings in Quarter Horses with heritable equine regional dermal asthenia.

OBJECTIVE To compare biomechanical and histologic features of heart valves and echocardiographic findings between Quarter Horses with and without heritable equine regional dermal asthenia (HERDA). DESIGN Prospective case-control study. ANIMALS 41 Quarter Horses.

Oral squamous cell carcinoma in a Vietnamese pot-bellied pig (Sus scrofa).

An 18-year-old, neutered, male Vietnamese pot-bellied pig (Sus scrofa) was treated for chronic, intermittent nasal discharge and sneezing. The animal was diagnosed with severe periodontal disease (grade IV), an oronasal fistula, and multiple tooth root abscesses via dental examination and computed tomography of the skull. Dentistry was performed, including multiple tooth extractions, and antibiotic therapy was initiated.

Paresis in an Asian small clawed otter (Aonyx cinereus) associated with vertebral and ischial osteolysis caused by a malignant lymphangiosarcoma.

A 10-yr-old male intact Asian small clawed otter (Aonyx cinerus) was presumptively diagnosed by histopathology and immunohistochemistry with lymphangiosarcoma after bony destruction of the ischium and spinal column from local tumor invasion had caused progressive signs of hind limb lameness and paresis/paralysis, which led to humane euthanasia. At necropsy, the primary tumor was identified as a flocculent mass present under the caudal lumbar vertebrae. Multiple nerves were seen to run from the spinal cord into the wall of the mass.

The clinical utility of the right lateral intercostal ultrasound scan technique in dogs.

When performing abdominal ultrasonography in dogs, the right aspect of the liver, porta hepatis, right kidney, right adrenal gland, pancreas, and duodenum are often not fully visible from a ventral, or subcostal, approach. The right lateral intercostal plane is an alternative approach that allows evaluation of these structures. This report provides multiple case examples that demonstrate the sonographic anatomy via the right intercostal approach.

The clinical usefulness of the ventrodorsal versus dorsoventral thoracic radiograph in dogs.

Differences exist in the ventrodorsal (VD) and dorsoventral (DV) radiographic views of the canine thorax. One view may be preferred over another because of how it portrays different areas of interest or different disease conditions. The VD view is indicated for evaluation of the cranial and caudal mediastinum, the caudal vena cava, and the accessory lung lobe, and in cases of pleural effusion.
