discospondylitis in 33 dogs.

Objective: To describe the clinical and imaging findings of 33 dogs with discospondylitis (BDS).

Animals: 33 client owned dogs from four veterinary specialty hospitals within Colorado and Arizona with at least one positive test and spinal diagnostic imaging.

Procedures: Retrospective review of signalment, physical and neurological examination findings, laboratory results, serology, and diagnostic imaging of 33 dogs with BDS.

Canine Butterfly Glioblastomas: A Neuroradiological Review.

In humans, high-grade gliomas may infiltrate across the corpus callosum resulting in bihemispheric lesions that may have symmetrical, winged-like appearances. This particular tumor manifestation has been coined a "butterfly" glioma (BG). While canine and human gliomas share many neuroradiological and pathological features, the BG morphology has not been previously reported in dogs.

Fiberoptic microneedle device facilitates volumetric infusate dispersion during convection-enhanced delivery in the brain.

Background And Objectives: A fiberoptic microneedle device (FMD) was designed and fabricated for the purpose of enhancing the volumetric dispersal of macromolecules delivered to the brain through convection-enhanced delivery (CED) by concurrent delivery of sub-lethal photothermal hyperthermia. This study's objective was to demonstrate enhanced dispersal of fluid tracer molecules through co-delivery of 1,064  nm laser energy in an in vivo rodent model.

Materials And Methods: FMDs capable of co-delivering fluids and laser energy through a single light-guiding capillary tube were fabricated.
