Body positioning and amount of recumbency time influence cranial migration of epidurally injected methylene blue. If greater cranial migration of an epidurally administered drug is desired, placing the patient in lateral recumbency with the surgical site on the dependent side may precede surgery.

Seven serum samples of 101 samples from nondomestic, captive and free-ranging felids from the United States were indirect fluorescent antibody positive for antibodies to Neospora caninum, whereas 44 samples were positive for antibodies to T. gondii. Although none of the captive animals displayed clinical signs of disease, nondomestic felids in the United States have been exposed to, and are likely infected with, N. caninum and T. gondii. This may have serious implications for zoological gardens exhibiting susceptible animals, such as kangaroos, close to felids.

The endoscope was first developed over 200 yr ago. Endoscopy has since been applied to many disciplines of medicine. Its application to the nervous system was initially slow and not widely accepted and mainly involved the biopsy of tumors and the treatment of hydrocephalus. Several reasons for neuroendoscopy's limited use include inadequate endoscope technology, high skill level required, the advent of the surgical microscope, and the development of other treatments such as ventricular shunting. Over the past 50 yr, improvements in optical glass lenses, fiber optics, and electrical circuitry has led to better equipment and a revival of neuroendoscopy. Neuroendoscopy is now used in many diseases in human medicine including hydrocephalus, neoplasia, and intracranial cysts. This review presents the history of neuroendoscopy, the equipment and technology used, and the possible translation of techniques currently used in human medicine to veterinary medicine.
