Term
How do corticosteroids provide analgesia?
Definition
By reducing the inflammation that causes pain.
Term
What sort of drugs are corticosteroids?
Definition
They are hormones!!
Term
DO corticosteroids tend to have long or short durations of action?
Definition
Long, all of the long
Term
What are the 6 major steps in the neuro exam?
Definition
1. Assessment of mental status and behaviour
2. Assessment of gait
3. Assessment of posture
4. Assessment of muscle integrity
5. Cranial nerve examination
6. Spinal reflexes
Term
What are the things that you are looking for when assessing the mental status and behaviour during a neuro exam?
Definition
Changes in appetite, depression, lethargy, unresponsiveness, anxiety, hyperactivity, hysteria, aggression, head pressing
Term
What are the things to look for with the assessment of gait?
Definition
Sensory - wide stance, swaying, loss of limb coordination, dragging toes
Cerebellar ataxia - over reaching or high stepping
Vestibular ataxia- head tilting, leaning falling, reluctance to move, side to side head swaying
Paresis/paralysis - total or partil loss of motor control
Tremor - rhythmic or oscillatory
Term
How do you assess posture?
Definition
Propreoception
Placing response, will the animal reach for a surface when susenpended
Hopping - Thoracic limbs
Wheel barrowing
Extensor postural thrust - does the animal stretch its hindlimbs to try to make contact with a surface when suspended?
hemistanding/hemiwalking
Term
What are the tests of the cranial nerves?
Definition
Facial symmetry
PLR
Menace response
Visial following
Palpebral response
Strabismus and nystagmus
Swallowing and gag
Term
How do you test spinal reflexes?
Definition
Extensor thrust (assesses muscle tone and femoral nerve)
Patellar reflex
Other refelexes
Deep pain withdrawal
Term
What are the main signs of UMN disease?
Definition
PAresis to paralysis, hyperreflexia, late and mild atrophy, muscle spasm and hypertonia, normal EMG
Term
What are the main signs of LMN disease?
Definition
Paralysis (flacid), hypo to areflexia, early and severe atrophy, abnormal EMG
Term
What are the contraindications of a myelograph?
Definition
Anything that contraindicates administering a GA
Paitents with increased intracranial pressure
Coagulopathy
Congenital abnormalities
Cervical trauma
RABIES!
Term
How much CSF can you take?
Definition
around 1ml/5kg (around 10 drops)
Term
What should you collect CSF in?
Definition
EDTA for presevation of cell morphology, red top for biochem
Term
What is degenerative joint disease?
Definition
A non-inflammatory disease of synovial joints where the cartilage degenerates and is replaced by the formation of bone at the joint surfaces
Term
What causes DJD?
Definition
Enzymatic degradation of the cartilage, though we do not know what initiates this?
Term
Is primary or secondary arthritis more common in dogs?
Definition
Secondary!
Term
What is secondary arthritis secondary to?
Definition
Joint instability, trauma other bone diseases
Term
Is DJD a chronic or acute disease process?
Definition
Chronic with a slow onset.
Term
Does DJD result in systemic signs?
Definition
Nope, it is confined to the musculockeletal system
Term
What is the progression of DJD?
Definition
Join pain, stiffness and loss of motion progressing to fibrosis, pain, decreased excercise tollerance, lameness and muscular atrohpy
Term
What are the aims of treatment for DJD?
Definition
Pallative, not curative.
The aim is to provide pain relief and to minamise the progression of the disease.
Term
What are some of the management factors needed for DJD?
Definition
Reduction of body weight
Controlled, regular excercise, depending on stage of disease and level of pin.
Passive movement of the joints in conjunction with NSAID therapy
Assisted excercise (swimming, slings etc)
Physical therapy (depending on what is available in the area and what the Ox wants to spend)
Term
What are the most commonly used NSAIDS in the treatment of DJD?
Definition
Meloxicam and carprofen
Term
Can you use corticosteroids to treat DJD?
Definition
Yes, BUT NEVER WITH NSAIDS AT THE SAME TIME
Corticotersoids are safe at low doses, but you can have problems if the treatment is continued long term
Term
What are some surgical options for the treatment of DJD?
Definition
Joint replacements (Hip, elbow and stifle)
Arthrodesis, immobilisation of the joint by fusion
Arthroplasty
Joint irrigation with saline or lactated ringers has been shown to provide short term improvements (months)
Term
What are the main concerns when looking after a paralysed paitent?
Definition
Respiratory system
Urinary system
integument
GIT dysfunction
Self trauma
Term
Why do giant and large breed dogs get respiratory issues after a long time in recumbancy?
Definition
Hypoventilation - the 'down' lung is unable to expand fully
Hydrostatic congestion
Increased risk of aspiration pneumonia
Decreased sensory stimulation to the brain centres for respiratory function
Term
What are some of the reasons for urinary incontinence?
Definition
Neuro - UMM, LMN
Non-Neuro - Ectopic ureters, sphincted incompetence, increased urethral closure pressure (mechanical or functional), overactive bladder
Term
How can you treat urinary incontinence?
Definition
Depends on the cause
Congentital deformity? Might be surgical!
Neoplasia? Also might be surgical!
Can give urethral bulking agents to increase the closing capacity of the sphincters
Urethral occuluders - I think it functions like an artificial sphincter. A cuff is inserted and the cuff diameter can be controlled by injecting saline into a port.
Term
Which is a UI condition that is treatable by hormones?
Definition
USMI - treated with oestrogen
Term
Can corticosteroids be used in the treatment of spinal injuries?
Definition
No, if trauma is suspected, this treatment bight be fatal
Term
What is laryngeal paralysis in the dog?
Definition
Pralysis of the aryenoid cartliages resulting in obstruction.
The diseases is commonly idopathic.
Term
What are the medical treatments for larengyal paralysis in the dog?
Definition
Anti-inflammatory doses of corticosteroids and cage rest
Term
What are the surgical options for the treament of larengeal paralysis?
Definition
Larngoplasty - the aim is to open the larynx without predisposing the dog to aspiration pneumonia.
The main surgery done is the unilateral aratenoid tieback procedure. Only one side is tied back to reduce the chance of aspiration.
The main landmarks for the procedure are the cricoid and thyroid cartilages.
Term
What is tracheal stenosis?
Definition
the narrowing of the trachea, due to damage or cogentital absence of the rings.
It results in a total or partial block of the trachea.
Treatment is surgical and may involve trachial resection or prosthesis to maintain the lumen.
