It’s Friday. The end of another working week.
Are you fagged out? Finding yourself in a fug?
Time for you know what — a fortified bolus of FFFF!!!
Q1. What does this photograph show and what was it used for?
- An ophthalmophantome.
- “This is an antique surgical training tool from the early 20th century. Animal eyeballs were clamped into the eye sockets so that budding ophthalmologists could practice their, er, chops.”
Q2. What is the ‘tattoo-to-teeth’ ratio and what does it indicate?
According to the LITFL’s Signs Of Imminent Admission:
- A general rule of thumb is that if the tattoo-to-tooth ratio (TTR) is greater than or equal to one, your patient is indestructible.
- The higher the TTR score, the lower the likelihood of a terminal outcome.
- A patient with a TTR of just two could be run over by a truck after being shot twice in the back outside of the bar in which he drank six fifths of whiskey, and shortly after admission to the emergency department he would be demanding cigarettes and sexual favors from any nearby persons.
Q3. How is Calabar (in modern times, a city in Nigeria) related to Argyll Robertson pupils?
According to Ophthalmology Befuddler 017 — Pupils and Prostitutes:
- Douglas Moray Cooper Lamb Argyll Robertson (1837-1909) was a Scottish ophthalmologist. He was the first to describe his eponymous pupillary abnormality among patients with tabes dorsalis (neurosyphilis).
- Argyll Robertson was also the first to demonstrate the cholinergic ocular effects of an extract from the Calabar bean, the drug physostigmine.
- Later, Argyll Robertson was consulted by a patient who lived in ‘Old Calabar’ about the ‘Calabar swellings’ that affected her eyes. He extracted filiarial Loa loa worms from these lumps and was thus one of the first to describe ocular loasis.
Q4. How did the C-reactive protein (every emergency physician’s favourite lab test) get its name?
Q5. According to Joseph Lister (1827–1912), what is the best dressing?
(Clue: he wasn’t talking about salad)
- Lister said: ‘skin is the best dressing’.
