I need an Atypical Rock Star Death
Everything this guy usually takes could cause this!
UDS negative for opiates, cocaine and amphetamines ? False negatives

Screw It
Differential too large
I’ve got better things to do
I’m not feeling the love
I need a new system approach
![Page 33: Clinical Pathological Case Presentation NACCT 2003](https://reader034.vdocuments.us/reader034/viewer/2022042718/56813fdf550346895daac8fe/html5/thumbnails/33.jpg)

Apologies to Dr. Elizabeth Kubler-Ross

Denial
I am good enough and smart enough and doggone it, people like me.
I have plenty of time to figure out the CPC!
![Page 35: Clinical Pathological Case Presentation NACCT 2003](https://reader034.vdocuments.us/reader034/viewer/2022042718/56813fdf550346895daac8fe/html5/thumbnails/35.jpg)
Anger
How the hell do they expect me to figure out this CPC!
Everything has a case report associating it with pulmonary edema!
Where are my fellows when I need them!
![Page 36: Clinical Pathological Case Presentation NACCT 2003](https://reader034.vdocuments.us/reader034/viewer/2022042718/56813fdf550346895daac8fe/html5/thumbnails/36.jpg)
Bargaining
Who can I bribe to figure out this CPC?
How can I cheat if at all possible?
![Page 37: Clinical Pathological Case Presentation NACCT 2003](https://reader034.vdocuments.us/reader034/viewer/2022042718/56813fdf550346895daac8fe/html5/thumbnails/37.jpg)

Depression
My differential just keeps getting larger.
Maybe there will be another blackout.
What do 4 out of 5 toxicologists recommend for an overdose?
![Page 39: Clinical Pathological Case Presentation NACCT 2003](https://reader034.vdocuments.us/reader034/viewer/2022042718/56813fdf550346895daac8fe/html5/thumbnails/39.jpg)
Acceptance
OK, the differential is enormous and there is little to narrow down the field so what answer is the most satisfying intellectually for an NACCT CPC?

The Shit That Killed Elvis
Elvis died in the bathroom.Slang term for high grade marijuanaPercodanDemerolAmphetaminesMyriad sedative hypnotics Methaqualone Barbiturates Ethchlorvynol

Marijuana
UDS positive for THC Doesn’t usually cause pulmonary edema Possible contaminant
PCP Ketamine Paraquat

Methaqualone
Used by Elvis
Reports of Pulmonary Edema
Schedule I since 1984 and reports are infrequent
Kids are making everything these days

Ethchlorvynol
Placidyl – sedative,hypnoticUsed by ElvisCauses NCPE when injected not usually when taken orallyAfter IV injection causes a minty taste in the mouth then dyspneaAbbott discontinued production in 1999.Is it available?
![Page 47: Clinical Pathological Case Presentation NACCT 2003](https://reader034.vdocuments.us/reader034/viewer/2022042718/56813fdf550346895daac8fe/html5/thumbnails/47.jpg)
Ethchlorvynol
The following ethchlorvynol cases have been reported to AAPCC TESS since 1/1/2000:
50 human cases as substance 1, no deaths
90 human cases total as one of the involved substances, no deaths
![Page 48: Clinical Pathological Case Presentation NACCT 2003](https://reader034.vdocuments.us/reader034/viewer/2022042718/56813fdf550346895daac8fe/html5/thumbnails/48.jpg)
