Blood vessels are needed to keep the liquid of life pumping throughout our bodies. Bad vessels lead to bad flow, which is undoubtedly a bad thing.
In this episode, Dr Gabrielle talks about vascular surgery, rather interesting stories and workplace injustice.

Here’s a sordid acronym: BITCH.
Acute abdominal pain
- Bleeding (haemorrhage)
- Twisting (torsion, leading to ischaemia)
- Congestion (obstruction)
- Hole (perforation)
- Ruptured AAA, ovarian cyst, ectopic pregnancy or abdominal organ
- Leads to haemoperitoneum, meaning blood in the abdominal cavity
- -itis of any organ in the abdominal area
- Just think of the anatomy in the region to come up with possibilities
- Appendicitis is the most likely surgical cause, while gastroenteritis is a common ailment of the masses
- Sigmoid volvulus
- Torsion of gonadal structures (ovaries or testes)
- Things that involve blockage
- Intestinal obstruction, ureteric obstruction from renal calculus or urinary retention
- Mesenteric ischaemia
- Perforated gastrointestinal structure
- Gastric or duodenal ulcers
Why do your feet swell during aeroplane flights? It’s not sudden-onset elephantiasis (probably).
Instead, it’s due to blood pooling in your veins. (As blood tends to do when stationary, thanks to gravity.)
Yes, gravity strikes again!

As delicious as they might be, persimmons can cause a phytobezoar. This refers to an indigestible clump of fibres that can lead to intestinal obstruction. (Everyone’s least favourite thing, unless you’re super weird!)
That’s an uncommon complication from eating too many of this fruit, not that eating fruit is inherently a bad thing.
Luckily, persimmon phytobezoars can be conquered with Coca-Cola.
It’s drinks such as that which, under normal circumstances, contain an excess of sugar. That’s in contrast to fruit. Ironically, in this case, the roles of causative agent and cure have been reversed.

Lipase is more specific for pancreatic disorders than amylase.
Lipase has a p in it. So does pancreas.
Amylase has nothing.

After you apply some wrapping around wet plaster, you might notice that the patient’s limb feels warm.
Is this simply a product of insulation?
No, it’s not just this reason.
It’s primarily because plaster and water form an exothermic reaction, so heat is released.
People can be burned by this!
