What is a collapsing pulse associated with
Aortic regurgitation
What are the murmur sounds
Aortic stenosis is the correct answer as it produces an ejection systolic crescendo decrescendo murmur (and a slow rising, narrow pulse pressure), heard loudest on expiration.
Mitral regurgitation produces an apical pansystolic murmur.
Aortic regurgitation produces an early diastolic decrescendo murmur (and a collapsing pulse)
Mitral stenosis produces an apical mid diastolic rumble.
Pulmonary stenosis produces an ejection systolic murmur heard loudest on inspiration.

What is typical presentation of IBS
Generalised abdominal pain which gets better after passing wind and/or defecation, bloating and changes in bowel habits typically suggest a case of IBS
Typical Px presentation of Crohn’s
Pain on the right side of the abdomen along with bloody stools and other extra-intestinal features such as mouth ulcers, erythema nodosum and episcleritis although these aren’t always the case
Typical Px presentation of UC
UC only affects the colon so it you tend to get pain in the lower left quadrant of the abdomen instead of generalised abdominal pain. Also, there is blood and mucus in the stool too
Explain Mallory Weiss tears
Mallory Weiss tears occur when there is a tear in the mucosal lining at the oesophagogastric junction due to a sudden increase in intra-abdominal pressure.
Things such as recurrent retching, vomiting etc. can force stomach contents into the oesophagus, dilate it and tear it resulting in haematemesis
First line medication for GORD
PPIs
Omeprazole
Other meds later on inc; H2 antagonist Rantidine
Most common cause of peptic ulcers and its MoA
H. Pylori
Lives in gastric mucus, secretes urease which splits urea in stomach into CO2 + ammonia.
Ammonia + H+→ammonium.
Ammonium, proteases, phospholipases and vacuolating cytotoxin A damages gastric epithelium.
_Causes inflammatory response reducing mucosal defence→mucosal damage_
Also causes increased acid secretion
i. Gastrin release (from G cells)→more acid secretion
ii. Triggers release of histamine→more acid secretion
iii. Increases parietal cells mass→more acid secretion
iv. Decreases somatostatin (released from D cells)→more acid secretion
How can NSAIDS cause peptic ulcers
Recurrent NSAID use is a common cause of peptic ulcers
a. Mucus secretion stimulated by prostaglandins
b. COX-1 needed for prostaglandin synthesis
c. NSAIDs inhibit COX-1
d. No COX-1 = mucous isn’t secreted
e. Reduced mucosal defence→mucosal damage
