Diagnose this patient

The psychology instructor had just finished a lecture on mental health and was giving an oral test.

Speaking specifically about manic depression, she asked, "How would you diagnose a patient who walks back and forth screaming at the top of his lungs one minute, then sits in a chair weeping uncontrollably the next?"

A young man in the rear raised his hand and answered, "A basketball coach?"

Carl Koller

Died 21 Mar 1944 at age 86 (born 3 Dec 1857).Czech-born American ophthalmic surgeon whose introduction of cocaine as a surface anesthetic in eye surgery on 16 Sep 1884 inaugurated the modern era of local anesthesia. He was a colleague of Sigmund Freud, who in 1884 was interested in the use of cocaine to cure morphine addiction. Koller noticed cocaine had a numbing effect on the tongue and, after experimenting with animals, introduced it as a local anaesthetic in ophthalmology. It was also quickly adopted for nose and throat surgery and for dentistry. Cocaine was isolated in 1859 and was synthesized in 1885. It became evident that this agent produced erosion of the corneal epithelium in high doses or with repeated use. Later, less toxic, synthetic local anesthetics such as tetracaine and proparacaine were developed.
