|
inflammatory
degenerative metabolic toxic neoplastic |
|
|
What is coonhound parlysis?
|
an inflammatory disease that results in acute ascending parlysis in dogs
lesion is demyelination and influx of inflammatory cells occurs after the scratch or bite from a raccoon reported in dogs and rarely in cars with no history of contact with raccoons and is called acute idiopathic polyradiculoneuritis |
|
|
What are the signs of coonhound paralysis?
|
hyperesthesia, weakness, ataxia, leading to tetra paresis that can last for weeks or months
recovery is common but can take a long time affected dogs develop extensive dennervation atrophy |
|
|
What is Neuritis of the cauda equina?
|
tail and sphincter paralysis in the horse that results from chronic inflammation of the extradural portions of the nerve roots of the cauda equina
can also affect lumbar ad other nerve roots The etiology is unknown lesions are thickened nerve roots die to moderate to severe inflammatory cell infiltration (lymphocytic) |
|
|
What are the signs of neuritis of the cauda equina?
|
perineal paresthesia-anesthesia, urinary incontinence, fecal retention, tail paralysis, croup muscle atrophy and hind limb ataxia weakness
|
|
|
What are examples of traumatic conditions that affect peripheral nerves?
|
avulsion of the brachial plexus in dogs
Amputation neuromas (tail dock neuroma in dogs) sequel of neurectoma of digital nerve in horses |
|
|
What is calving paralysis?
|
bilateral compressive damage of the obturator nerves
complication of dystocia in heifers with oversized fetuses animals are unable to adduct their muscles and can affect the sciatic nerve Animals are splay leg |
|
|
What is diabetic neuropathy?
|
seen in cats
nerves are affected Hind limb weakness with characteristic plantigrate stance, muscle wasting and proprioceptive abnormalities Often associated with amyloid deposition in the pancreatic islets |
|
|
T/F
Lead, thallium and mercury are not possible results of peripheral neuropathies |
False

|
|
What is Vincristine neuropathy?
|
Vincristine sulfate made from an alkaloid plant Vinca rosea that has antineoplatic properties and is used in human and veterinary oncology to treat tumors
see peripheral neuropathy however it is reversible and an accepted sequel to therapy causes neurotubule breakdown which leads to impaired axonal transport and axonal degeneration |
|
|
What are examples of primary tumors that affect the PNS?
|
ganlioneuromas
ganglioneuroblastomas peripheral nerve sheath tumores |
|
|
What is an example of secondary tumors that affect the PNS?
|
rare
Marek's disease |
|
|
What is Merek's disease?
|
Gallid Herpes Virus
induces lymphoma in chickens which can involve the viscera, eyes, CNS and PNS. Spinal lymphosarcoma in cats and cattle can occasionally involve spinal nerve roots |
