25
Why may patients with aortic stenosis get frequent nosebleeds and easy bruising?
The blood moving through the stiffened valve can disform von Willebrand factor, causing an acquired von Willebrand disease
26
Causes of chronic aortic regurgitation
hypertension, a congenital bicuspid valve, degeneration such as calcification, connective tissue disorders e.g. Marfan's
27
Causes of acute aortic regurgitation
rheumatic heart disease aortic dissection infective endocarditis
28
Murmur in mitral stenosis
low-pitched rumbling diastolic murmur over the mitral area
29
Medication in aortic stenosis
Diuretics for symptom relief | Consider anticoagulant prophylaxis as increased risk of clots
30
Treatment of acute limb ischaemia
given anti-platelets (e.g. aspirin), anticoagulants (e.g. heparin) and analgesia (e.g. an opioid) Consideration for surgery (revascularisation if limb is viable or amputation of limb isn't viable)
31
Medication in mild - moderate peripheral vascular disease
Anti-platelets
32
Symptoms of HHS
polyuria, polydipsia, headache, nausea, vomiting and abdo pain, tachycardia, hypotension and confusion
33
Cancer most associated with Cushing's
Small cell lung cancer
34
First line investigation in Cushing's
24 hour urinary cortisol
35
Investigation of acromegaly
First line is look for raised serum IGF-1 Then oral glucose suppression test (growth hormone will remain high) Then MRI to look for pituitary tumour
36
Complications of acromegaly
Diabetes Hypertension Cardiomyopathy Sweating Sleep apnoea (due to increased tongue size) Colon cancer (screened for on diagnosis with a colonoscopy) Reduced secretion of other pituitary hormones due to pituitary compression or visual field defects due to optic chiasm compression
37
Investigation of Cushing's
First line test is usually 24-hour urinary cortisol Midnight cortisol can be taken to show loss in circadian rhythm (it’s usually lowest at night) Low dose dexamethasone suppression test involves giving a low dose of dexamethasone at 11pm then measuring serum cortisol at 8am and showing a lack of suppression Once Cushing’s is confirmed and exogenous steroid use excluded, serum ACTH may be measured to see if it is ACTH dependent. The ACTH can be measured after a high-dose dexamethasone suppression test to see if the ACTH is from the pituitary gland (ACTH will fall) or an ectopic source (ACTH will stay high). If carcinoma suspected, give CT/MRI scan
38
Treatment of prolactinoma
dopamine agonists (e.g. cabergoline) to reduce prolactin levels via negative feedback and shrink the tumour. If unresponsive to this, surgery may be considered
39
SIADH treatment
Diuretics and treatment of the cause if appropriate. In some patients tolvaptan may be used, which is a competitive inhibitor of ADH
40
First line investigations in Addison's
U&Es will show hyperkalaemia and hyponatraemia (due to low aldosterone). 9 am cortisol would be measured (should be highest at this time)
41
How to interpret 9am cortisol in diagnosis of Addison's
If very low, admit to hospital. If slightly low, refer for a synacthen test. If normal or high Addison’s is unlikely.
42
Symptoms of Addisonian crisis
dehydration, hypotension, confusion, abdominal pain, diarrhoea and vomiting, hyponatraemia and hyperkalaemia.
43

There may also be symptoms associated with inflammation in specific tissues.
59
Medications in SLE

106
Imaging in chronic pancreatitis
CT scan to look for duct atrophy, calcification or dilation Secretin enhanced MRI or MRCP scan Endoscopic ultrasound to assess the duct walls
107
Conservative management of chronic pancreatitis
Lifestyle advice (smoking and alcohol cessation) Pain relief (NSAIDs initially but often opioids are needed) In patients with ductal strictures, ERCP can be used to insert a stent into the ducts which can reduce pain Lipase supplements to reduce the symptoms of malabsorption In around a third of patients (particularly those with small vessel disease), giving supplements of pancreatic enzymes improves symptoms.
108
How pancreatic enzyme supplements are given
Trial for 1 month then continued for 6 months at a time if symptoms improve
