Paradoxical vestibular syndrome in a dog from western Newfoundland infected with French heartworm .

A dog from western Newfoundland was presented with paradoxical vestibular syndrome. First-stage larvae of were detected on fecal examination. Treatment with milbemycin oxime resulted in resolution of signs.

Interobserver agreement and diagnostic accuracy of brain magnetic resonance imaging in dogs.

Objective: To evaluate interobserver agreement and diagnostic accuracy of brain MRI in dogs.

Design: Evaluation study.

Animals: 44 dogs.

Clinical and MRI findings in three dogs with polycystic meningiomas.

One spayed female Labrador retriever and two castrated male golden retrievers were evaluated for chronic (i.e., ranging from 3 wk to 24 wk) neurologic signs localizable to the prosencephalon.

Incidence of and risk factors for seizures after myelography performed with iohexol in dogs: 503 cases (2002-2004).

Objective: To establish the incidence of and risk factors for seizures following myelography performed with iohexol in dogs.

Design: Retrospective case series.

Animals: 503 dogs.

Investigation of the use of three electroencephalographic electrodes for long-term electroencephalographic recording in awake and sedated dogs.

Objective: To compare electroencephalography (EEG) artifact associated with use of the subdermal wire electrode (SWE), gold cup electrode (GCE), and subdermal needle electrode (SNE) over an 8-hour period in sedated and awake dogs.

Animals: 6 healthy dogs.

Procedures: 8 EEG channels were recorded during 20-minute video-EEG recording sessions (intermittently at 0.

Outcome of medical and surgical treatment in dogs with cervical spondylomyelopathy: 104 cases (1988-2004).

Objective: To compare outcomes and survival times for dogs with cervical spondylomyelopathy (CSM; wobbler syndrome) treated medically or surgically.

Design: Retrospective case series.

Animals: 104 dogs.

Ultrasound-guided fine needle aspiration in the diagnosis of peripheral nerve sheath tumors in 4 dogs.

Ultrasound-guided fine needle aspiration was used in establishing the diagnosis in 4 cases of malignant peripheral nerve sheath tumor. Sonographic and cytologic characteristics are discussed. Because of its availability and ease of use, axillary ultrasonography with fine needle aspiration can be an initial diagnostic step for suspected brachial plexus tumors.

One-year clinical and magnetic resonance imaging follow-up of Doberman Pinschers with cervical spondylomyelopathy treated medically or surgically.

Objective: To evaluate progression of clinical signs and magnetic resonance imaging (MRI) findings in dogs with cervical spondylomyelopathy (wobbler syndrome) treated medically or surgically.

Design: Prospective cohort study.

Animals: 12 Doberman Pinschers.

Correlation of motor evoked potentials with magnetic resonance imaging and neurologic findings in Doberman Pinschers with and without signs of cervical spondylomyelopathy.

Objective: To establish the reference ranges for motor evoked potential (MEP) latency and amplitude in clinically normal Doberman Pinschers, compare the MEPs of Doberman Pinschers with and without clinical signs of cervical spondylomyelopathy (CSM; wobbler syndrome), and determine whether MEP data correlate with neurologic or magnetic resonance imaging (MRI) findings.

Animals: 16 clinically normal and 16 CSM-affected Doberman Pinschers.

Procedures: Dogs were classified according to their neurologic deficits.

Morphologic and morphometric magnetic resonance imaging features of Doberman Pinschers with and without clinical signs of cervical spondylomyelopathy.

Objective: To compare morphologic and morphometric features of the cervical vertebral column and spinal cord of Doberman Pinschers with and without clinical signs of cervical spondylomyelopathy (CSM; wobbler syndrome) detected via magnetic resonance imaging (MRI).

Animals: 16 clinically normal and 16 CSM-affected Doberman Pinschers.

Procedures: For each dog, MRI of the cervical vertebral column (in neutral and traction positions) was performed.

Cervical syringohydromyelia secondary to a brainstem tumor in a dog.

An 11-year-old male Pekingese was evaluated because of a history of head tilt. Neurologic examination revealed a right-sided head tilt, ataxia, scoliosis, and proprioceptive deficits. Diagnostic testing included magnetic resonance imaging (MRI) of the head and neck.

Recurrence of thoracolumbar intervertebral disk extrusion in chondrodystrophic dogs after surgical decompression with or without prophylactic fenestration: 265 cases (1995-1999).

Objectives: To evaluate a population of chondrodystrophic dogs treated for Hansen type 1 intervertebral disk (IVD) disease by surgical decompression with or without prophylactic fenestration and determine the rate and location of surgically confirmed recurrence of intervertebral disk extrusion.

Animals: 265 dogs.

Study Design: Retrospective study.

Correlation between severity of clinical signs and motor evoked potentials after transcranial magnetic stimulation in large-breed dogs with cervical spinal cord disease.

Objective: To evaluate use of transcranial magnetic motor evoked potentials for assessment of the functional integrity of the cervical spinal cord in large-breed dogs with cervical spinal cord disease.

Design: Randomized, controlled, masked study.

Animals: 10 healthy large-breed control dogs and 25 large-breed dogs with cervical spinal cord diseases.
