Exploring brain perfusion in dogs with meningoencephalitis of unknown origin: A promising role for arterial spin labeling imaging.

Background: Arterial spin labeling (ASL) is a noninvasive brain perfusion magnetic resonance imaging (MRI) technique that has not been assessed in dogs with meningoencephalitis of unknown origin (MUO).

Hypothesis/objectives: Assess brain perfusion changes characteristics before and after medical treatment, and investigate the role of ASL perfusion in the diagnosis and prognosis of MUO in dogs.

Animals: Thirty-one dogs with presumed MUO.

Immune-mediated polyneuropathy in cats: Clinical description, electrodiagnostic assessment, and treatment.

Background: Suspected immune-mediated polyneuropathy has been increasingly reported in cats, especially in the last decade, but the condition remains poorly understood.

Objectives: Refine the clinical description and review the classification of this condition based on electrodiagnostic investigation and evaluate the benefit of corticosteroid treatment and L-carnitine supplementation.

Animals: Fifty-five cats presented with signs of muscular weakness and electrodiagnostic findings consistent with polyneuropathy of unknown origin.

Epidemiology and clinical presentation of canine cataracts in France: a retrospective study of 404 cases.

Objective: To determine the epidemiology and the clinical presentation of cataracts in a population of dogs in France.

Procedures: Records of dogs affected by a cataract presented at the Ophthalmology Unit of Alfort Veterinary School during 2009-2012 were reviewed. The etiology was determined for each dog.
