Q

What is the definition of a stroke vs TIA?

A
  • TIA: a transient episode of neurologic dysfunction due to the focal brain, spinal cord, or retinal ischemia without acute infarction or tissue injury. (<24h)

What is the other model of frailty (not phenotypic)?
Cumulative Deficit Model
91
Describe the Cumulative Deficit Model?
Described by Rockwood in Canada, it assumes an accumulation of deficits (ranging from symptoms e.g. loss of hearing or low mood, through signs such as tremor, through to various diseases such as dementia) which can occur with ageing and which combine to increase the ‘frailty index’, which increases the risk of adverse outcomes

What is the mechanism of hyperandrogenism in PCOS?
Insulin resistance is a crucial part of PCOS. When someone is resistant to insulin, their pancreas has to produce more insulin to get a response from the cells of the body. Insulin promotes the release of androgens from the ovaries and adrenal glands. Therefore, higher levels of insulin result in higher levels of androgens

What is the pathophysiology of anky spon?
- Main joints affected = sacroiliac joints and the joints of the vertebral column - tends to be symmetrical - Inflammation in vertebra occurs in the corner and bone marrow oedema develops - Fat is deposited in the corner of the vertebra as a result of oedema - This encourages new bone formation and calcium deposition over time in the ligaments of the spine - This fuses the spine and results in a question mark posture, where they cannot move their head or spine or neck
145
What changes would be seen on an x-ray for anky spon?

What are the stages of chronic peripheral artery disease?
Develops from intermittent claudication (walking small distances increases metabolic demands of the muscle, causign pain in te calf, thigh or buttock that abates after rest, as a result of the narrowing of the peripheral arteries) ⇒ rest pain (inadequate oxygen supply to allow it to function normally at rest) ⇒ night pain (when it gets so bad it happens at night because they lose gravity as a driver of circulation when they’re led down) ⇒ critical limb ischaemia (demands aren’t being met to keep tissue alive) ⇒ loss of limb
168
What surgeries might be offered for intermittent claudication and critical limb ischaemia?
- Endovascular angioplasty and stenting - inserting a catheter under Xray guidance, and inflating a balloon at the site of stenosis and then a stent to hold the artery open - Endarterectomy – cutting the vessel open and removing the atheromatous plaque - Bypass surgery – using a graft to bypass the blockage. Better patency and limb salvage but higher risk of morbidity and mortality
169
What surgeries might be offered for acute limb ischaemia?
- Endovascular thrombolysis – inserting a catheter through the arterial system to apply thrombolysis directly into the clot - streptokinase or alteplase - Endovascular thrombectomy – inserting a catheter through the arterial system and removing the thrombus by aspiration or mechanical devices - Amputation if it is not possible to restore blood flow
