A lot of these are still used, although some in slightly different contexts. A few of them could still be seen on death certificates. I have to wonder how the author decided on the list. Just looking at the first few letters:

We still describe widespread oedema as anasarca. Apoplexy is still used, but only really in the context of pituitary apoplexy. Atrophy is of course still in use. Cerebritis is still used. Cholera, obviously. Chorea is still a description of abnormal movements (Huntington's Chorea, Sydenham's Chorea etc.) Colic still used to describe a certain kind of abdominal pain. Congestion is still a term. Coryza is still used to describe the collection of symptoms you get from an URTI. Cyanosis is still the correct term. Cystitis is still the term for bladder inflammation.

Goes on and on...
