In human beings, diabetes mellitus (DM) and diabetic ketoacidosis (DKA) are recognized as proinflammatory states and dysregulation of cytokines has been linked to some potentially fatal complications. Cytokine profiles of dogs with DM or DKA have not been reported. The objectives of this study were to compare cytokine and hormone concentrations in dogs with DKA before and after resolution of ketoacidosis, to compare these concentrations before treatment of DKA to those measured in dogs with uncomplicated DM and healthy dogs, and to compare concentrations in dogs with uncomplicated DM to those measured in healthy dogs.

January 2009

Department of Clinical Studies, Matthew J. Ryan Veterinary Hospital of the University of Pennsylvania, School of Veterinary Medicine, University of Pennsylvania, Philadelphia, PA, USA.

This report describes computed tomography (CT)-guided stereotactic brain biopsy using the Kopf stereotactic system, a commercially available patient restraint system which does not require additional modification for use in small animals. The accuracy of biopsy needle placement was determined by injecting dilute iohexol into cadaver brains and comparing the three-dimensional coordinates of the desired target location to the actual needle tract observed on postcontrast CT images. Overall mean error in needle placement in a dorsoventral trajectory was 0.
