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. The format is starting to take shape – we will be trying to post questions on:
- Rare or eponymous syndromes
- Medical history or biography
- Bizarre and ‘out there’ medical trivia to baffle your colleagues
- What is an interrobang?
- You don’t know what an interrobang is‽
- The interrobang or interabang is a quesclamation mark (‽)
- Many writers, especially in informal writing, have used multiple punctuation marks to end a sentence expressing surprise and question.
- American Martin K. Speckter invented the interrobang in 1962 as an exclamation mark superimposed on a questions mark. Speckter believed that advertisements would look better if copywriters conveyed surprised rhetorical questions using a single mark.
- In fact the failed Aussie tourism advertising campaign may have fared better had they used the interrobang:
- Where the bloody hell are you ‽
- Perhaps more controversial is the gnaborretni (interrobang backwards). A reverse and upside down interrobang (combining ¿ and ¡, Unicode character: ⸘), suitable for starting phrases in Spanish, Galician and Asturian…
- So go on…why not use one today‽
- On what part of the body do melanomas most commonly develop in African-Americans?
- The Feet
Reference: Journal of Foot and Ankle Research
- Although relatively uncommon, malignant melanoma in African-Americans and other minority ethnic populations represents an aggressive disease highly associated with invasive lesions and a more advanced stage of disease at diagnosis, and consequently with a decreased survival compared with Caucasians.
- Caucasians have a predilection to develop lesions on sun-exposed surfaces such as the face and neck.
- However dark-skinned individuals have lesions predominantly located on sun-protected mucosal and acral sites, particularly the foot. [Reference: Dermatology Online Journal]
- Where is the sinus of Keith?
- Immediately posterior to the coronary sinus.
- The lower medial corner of the right atrium is variously termed “the appendix autricildaris of His” or “the sub-eustachian sinus of Keith“. From it the coronary sinus extends toward the left side of the heart and upward so as to form an angle of 40 to 70 degrees with a line drawn between the caval orifices.

- Dr Arthur Keith (1866-1955)
- What would a Hollywood star with dewlap do?
- Have plastic surgery.
- A dewlap is a longitudinal flap of skin that hangs beneath the lower jaw or neck of many vertebrates.
- In humans, the formation of a dewlap is prevented by the attachment of the deep cervical fascia to the hyoid bone.
- However…with age…this skin loosens and extends, leaving folds of skin hanging around the neck and jaw.
- Who might be regarded as the father of IV therapy?
- Sir Christopher Wren (of St. Paul’s Cathedral fame)
- In 1656 Sir Christopher injected opium intravenously into dogs using a quill and bladder, thereby becoming the father of modern IV therapy… and the first drug pusher (at least for canines).
