1/🧵 Ever wonder why tick bites can lead to a red meat allergy, including even anaphylaxis? The answer requires us to examine sugars, tick saliva, and an anti-cancer drug. #medtwitter #tweetorial
1/THREAD Have you ever wondered why sunlight exposure can make someone sneeze, aka 'photic sneezing'? The photic sneeze reflex is a real thing, and reflects some cool neurophysiology. It also sports perhaps the greatest acronym in medical history. Let's explore! #tweetorial
🥵🌶️ "Careful application of topical capsaicin diluted to 25 μg/ml to the right anterior nasal fossa provoked an uncomfortable burning sensation and local rhinorrhoea; however, sneezing was not precipitated."

Als Besitzer eines photischen Niesreflex bin ich über diesen Thread begeistert, vor allem da ich jetzt weiß, dass das auch ACHOO heißt ;)

As a kid I thought I was allergic to report cards—mom opened the curtains, my genes ran the ACHOO protocol. Turns out it wasn’t fear, it was optic–trigeminal crosstalk. Sorry, Mom. 😂

ACHOO!
I have this (like many people) so fascinating to read more about it.
2/ Perhaps the first to question why sunlight exposure can provoke sneezing was Aristotle. In The Book of Problems (XXXIII, Problem 10), he asked, "Why is it that one sneezes more after one has looked at the Sun?" loebclassics.com/view/aristotle… cosmosmagazine.com/science/biolog….
17/SUMMARY: 🌞Photic sneezing, aka ACHOO, involves sneezing in response to sunlight (and bright light in general) 🌞Aristotle and Francis Bacon both wondered about mechanism 🌞Current theories invoke optic-trigeminal summation and visual cortex sensitivity to light stimulation
This should of course be the 1500-1600s 🤦🏻
