Novel subcutaneous cytarabine infusion with the Omnipod system in dogs with meningoencephalomyelitis of unknown etiology

AMERICAN JOURNAL OF VETERINARY RESEARCH, 83(9).

By: S. Mancini n, P. Early n, B. Slater n, N. Olby n , C. Mariani n , K. Munana n , C. Woelfel n, J. Schacher n, L. Zhong  n, K. Messenger n

MeSH headings : Animals; Area Under Curve; Chromatography, High Pressure Liquid / veterinary; Cytarabine / therapeutic use; Dogs; Half-Life; Humans; Infusions, Intravenous / veterinary; North Carolina
TL;DR: An SC continuous-rate infusion of cytarabine via the Omnipod system is feasible in dogs and was able to achieve a steady-state concentration of more than 1 μg/mL 4 to 10 hours postinitiation of cyTarabine and a Cmax of 7,510 ng/mL, comparable to values reported previously with IV continuous- rate infusion administration in healthy research Beagles and dogs with meningoencephalomyelitis of unknown etiology.

MeSH headings : Animals; Cauda Equina / diagnostic imaging; Dog Diseases; Dogs; Magnetic Resonance Imaging / veterinary; Pain / veterinary; Prospective Studies; Reproducibility of Results; Syringomyelia / diagnostic imaging; Syringomyelia / veterinary
TL;DR: Painful CKCS without SM have decreased distance between the termination of the spinal cord and dural sac, suggesting a shorter FTIL, and more caudal spinal cord termination is associated with development of lumbar SM. (via Semantic Scholar)

Outcomes and prognostic indicators in 59 paraplegic medium to large breed dogs with extensive epidural hemorrhage secondary to thoracolumbar disc extrusion

VETERINARY SURGERY, 50(3), 527–536.

By: C. Woelfel n, J. Robertson n , C. Mariani n , K. Munana n , P. Early n & N. Olby n 

MeSH headings : Animals; Cohort Studies; Dog Diseases / diagnosis; Dog Diseases / surgery; Dogs; Female; Hematoma, Epidural, Spinal / complications; Hematoma, Epidural, Spinal / surgery; Hematoma, Epidural, Spinal / veterinary; Intervertebral Disc Degeneration / complications; Intervertebral Disc Degeneration / surgery; Intervertebral Disc Degeneration / veterinary; Laminectomy / statistics & numerical data; Laminectomy / veterinary; Male; Paraplegia / diagnosis; Paraplegia / surgery; Paraplegia / veterinary; Prognosis; Recovery of Function; Retrospective Studies; Species Specificity; Treatment Outcome; Walking
TL;DR: Paraplegic medium to large breed dogs with DEEH have a less favorable outcome after surgical decompression than paraplegic dogs with TL-IVDE, and loss of pain perception and increased HASTEi are associated with a poor outcome, while more extensive decompression improves outcome.
