It indeed has been a very long time since my last entry. This time around, let’s focus on something different. I’d like to talk about medical myths and how they might wreak havoc in your lives. No, I don’t mean the food fads, the herbal remedies your grandma made popular and all that. This article’s meant for the doc in training.
Consider this question:-
What antibody response is typical of Extrinsic Allergic Alveolitis?
In case you hadn’t read about this disorder’s immunology specifically, your survival instincts would have immediately led you to say IgE. Given the utterly memory-oriented way our brain functions in modern medical study, it immediately homes onto specific keywords in the question. Allergy and IgE go hand in hand don’t they? Well, not in this case they don’t. The correct answer here happens to be IgG.¹ Examinations such as the USMLE will test you with these odd-balls and boy do they constitute a bunch! Regardless of the ethical issues concerning what should or shouldn’t be tested in medical examinations, knowing the right responses to such questions and indexing them to one’s already burdened memory can indeed make or break one’s career.
There’s another oddity that you’d be interested to know about Extrinsic Allergic Alveolitis. This is one lung disorder that has a lower incidence rate among smokers!²
That’s it for now. Hope you’ve found this post interesting. Your comments are welcome as always. Until my next post, Ciao!
