Funtabulously Frivolous Friday Five 162

Just when you thought your brain could unwind on a Friday, you realise that it would rather be challenged with some good old fashioned medical trivia FFFF, introducing the Funtabulously Frivolous Friday Five 162

Question 1

What is a Sutherland wrap?

Reveal the funtabulous answer

Pressure bandage with immobilisation (PBI) for snakebite in Australia

It was developed in the 1970s by Straun Sutherland (1936-2002) as a first-aid measure. [Reference]


Question 2

What did Dutch physiologist Hartog Jacob Hamburger invent and was subsequently referred to as “normal xxxxx

Reveal the funtabulous answer

Saline

During the late 1800 doctors were trying to treat cholera patients with intravenous fluids based on Thomas Latta’s work in 1832. Various mixtures of sodium, chloride, potassium and bicarbonate were used but haemolysis was common.

Hamburger created a solution with 0.9% NaCl and observed no haemolysis to red blood cells incorrectly concluding this was the normal concentration in blood (its 0.6%) and hence the term “normal saline” was adopted. The solution is however, isotonic and therefore haemolysis does not occur.


Question 3

Who gets Pigbel?

Reveal the funtabulous answer

Typically Children of Papua New Guinea

Pig Bel is a form of acute, segmental, necrotizing enteritis presenting as a common and life-threatening disease. It relates to the consumption of contaminated pig meat and is thought to be caused by Clostridium welchii type C (an organism not usually present in the human intestine).

The perfect storm occurs during ceremonial feasts when large amounts of pork with contaminated bowels are eaten with sweet potatoes. Sweet potatoes contain a trypsin inhibitor. C. perfringens is normally digested by trypsin but its low levels secondary to a sweet potato meal result in increased levels of toxin. [Reference]


Question 4

What is Fagan famous for in evidence-based medicine?

Reveal the funtabulous answer

nomogram

The Fagan nomogram converts pre-test probabilities into post-test probabilities using the likelihood ratio for any given test.

Fagan Nomogram demo
An example of the determination of post-test probability using a Fagan Nomogram, by drawing a line that intersects the known pre-test probability (prevalence) of 0.25 and the likelihood for a negative result (in this example) of 0.1. The post-test probability is 0.03.

Question 5

Who has candle bones?

Reveal the funtabulous answer

Patients with Léri Disease (Melorheostosis)

It is an uncommon mesenchymal dysplasia manifesting as regions of sclerosing bone with a characteristic dripping wax appearance or flowing candle wax appearance.
