Q

Give a description of Reed Sternberg cells and then the name (reed sternberg cells)?

A

LARGE MULTINUCLEATED CELL, nucleus bilobed? prominent nucleolus?

B lymphocytes mutate into 2 types of cell:

Q

Interpret Odds ratio:

A
  • If Odds ratio = 1, then no assoc between exposure + disease
  • If Odds ratio more than 1, means positive association, so means exposure causes the disease defo
  • If Odds ratio less than 1, means negative association, so means exposure protects against disease

Q

What are the MOA of the different Parkinsons meds? (5 things) (M list, not sure if acc q or relation to levodopa / carbidopa q from R list)

A
  1. Levodopa = precursor to dopamine, converted to dopamine in brain
  2. Carbidopa = peripheral decarboxylase inhibitor, stops levodopa being broken down peripherally
  3. Pramipexole = dopamine agonist, reduce levodopa dose needed
  4. Rasagiline = MAO-B inhibitor, stop dopamine breakdown in brain
  5. Entacapone = COMT inhibitor, stops dopamine breakdown peripherally

Q

Why are levidopa and carbidopa used instead of just dopamine for Parkinsons? (4 points)

A
  1. Because dopamine can’t cross BBB
  2. Parkinsons is shortage of dopamine inside brain, so you need to get dopamine to brain
  3. Levidopa can cross BBB
  4. But need to give Carbidopa to stop levodopa from being broken down before it reaches brain

Q

Why do Parkinsons pt get choreiform movements? (3 things)

A
  1. Bc Levodopa
  2. Meds taken several times per day

Q

What is the pathophysiology of Parkinsons? (it’s a fill in gap question) (4 points)

A
  1. Parkins is neurodegenerative disorder
  2. Substantia nigra (in basal ganglia) degenerate
  3. So no more dopamine produced
