The ages of the Maltese dogs ranged from 9 months to 4 years. Four dogs were male, and one was female. The dogs had a history of seizures with or without(More)
Deficiency of glycogen branching enzyme (GBE) activity causes glycogen storage disease type IV (GSD IV), an autosomal recessive error of metabolism. Abnormal glycogen accumulates in myocytes, hepatocytes, and neurons, causing variably progressive, benign to lethal organ dysfunctions. A naturally occurring orthologue of human GSD IV was described previously(More)

In the present study, 2 cases of confirmed canine lycoperdonosis are described. The first case presented to the Matthew J. Ryan Veterinary Hospital of the University of Pennsylvania, and the second case was submitted for(More)
OBJECTIVE To document the clinical, clinicopathologic, and pathologic findings in cats with severe sepsis, identify abnormalities unique to this species, and identify criteria that could be used antemortem to diagnose the systemic inflammatory response syndrome in cats. DESIGN Retrospective study. ANIMALS 29 cats confirmed to have severe sepsis at(More)
OBJECTIVE To identify risk factors associated with fatal acute pancreatitis in dogs. DESIGN Case-control study. ANIMALS 70 case dogs with clinical evidence and histopathologic confirmation of fatal acute pancreatitis and 104 control dogs that had trauma, underwent necropsy, and did not have histologic evidence of acute pancreatitis. PROCEDURE(More)
A retrospective review of records of 205 cats with histologically confirmed disease of the spinal cord was performed to identify the prevalence of disease in this nonrandomly selected population of cats. Clinical records were reviewed, and age, duration of neurologic illness, and clinical and histopathologic findings in cats with spinal cord disease were(More)
OBJECTIVE To determine clinical, clinicopathologic, radiographic, ultrasonographic, and coagulation abnormalities in dogs in which acute pancreatitis was fatal. DESIGN Retrospective study.
