Some Librarian points us to a 2006 article in Singapore's Annals of the Academy of Medicine entitled Interesting In- and Outpatient Attendances at Hogwarts Infirmary and St Mungo's Hospital For Magical Maladies.
PubMed's abstract says
"Ailments afflicting wizarding folk are underreported in the muggle world. The recent integration of muggles and magical folk with the return of You-Know-Who (aka He Who Must Not Be Named) may result in a similar affliction of inhabitants of both worlds. We describe interesting maladies afflicting muggles and wizarding folk alike, arising from the use and misuse of magic. We also provide a basic glossary of magical ailments, and describe their muggle corollaries. Further studies will hopefully result in the development of immunity against the unforgivable curses."
And you can read the full article at the journal's web site.
