Tox Tunes #113: Legend of a Mind (Moody Blues)
“Legend of a Mind” is about Timothy Leary, the one-time Harvard professor of psychology and 1960s LSD-mountebank Timothy Leary, whom Richard Nixon once called the “most dangerous man in America.” Timothy Leary’s Dead No, no, he’s outside looking in He’ll fly his astral plane Takes you trips around the bay Brings you back the same day Timothy Leary, Timothy Leary Despite this funereal first verse, the song long pre-dated Leary’s death in 1996, and appeared on The Moody Blues 1968 progressive rock album In Search of the Lost Chord. “Legend of a Mind” was writte...

The 8th Annual Alexander Awards: The Best Tox Reading of 2017
Alexander Gettler Once again, last year’s outstanding examples of long-form journalism dealing with topics related to medical toxicology were dominated by coverage of the opioid crisis, its origins and the resulting carnage. The must-read article of the year was “The Family That Built a Empire of Pain,” Patrick Radden Keefe’s massive history of the Sacklers, one of America’s richest clans, much of whose wealth comes from their ownership of Purdue Pharma and the marketing and distribution of Oxycontin. The article, which appeared in the New Yorker, notes that the clan’s patriarch, Ar...

Lipid rescue therapy for local anesthetic toxicity: is less more
DISCUSSION: Most of the “adverse events” associated with lipid rescue therapy have occurred after administration of relatively high doses. Although there have been no good studies demonstrating the maximum “safe” dose of intralipid for lipid rescue therapy, many authors recommended limiting the dose to that recommended by the FDA for nutritional support: 12.5 mL/kg (lean body mass) per day total. In specific cases it may be reasonable to consider extending the infusion beyond this, but such situations are likely rare. In this patient, who did not appear to have cardiovascular instability, it is...

More myths and legends are attached to the life of Robert Johnson (1911 – 1938) than surround any other American blues artist. It’s said that he sold his soul to the devil down at a Mississippi crossroads in return for the ability to play guitar with a technique that musicians like Eric Clapton are still trying to replicate. It’s said that his death at age 27 established a precedent for other great American musicians who also died at that same age, including Jimi Hendrix, Janis Joplin, Jim Morrison, and Al “Blind Owl” Wilson.

Labetalol in acute cocaine toxicity: is it safe?
3 out of 5 stars Acute Toxicity from Topical Cocaine for Epistaxis: Treatment with Labetalol. Richards JR et al. J Emerg Med 2017 Mar;52:311-313. Abstract There has long been a debate among toxicologists — still unresolved — as to whether it is safe to use a beta-blocker to treat cocaine-related hypertension and tachycardia. The (theoretical) concern is that since cocaine is both an α- and a β-agonist, blocking the β-receptors could lead to unopposed α stimulation with increased severe hypertension. Some authors contend that in this setting, labetalol would be safe since it blocks bot...

Did the nerve agent VX kill Kim Jong Nam?
Last night Malaysian authorities announced that they identified the nerve agent VX taken off the face of Kim Jong Nam, who was murdered on February 13 at Kuala Lumpur International Airport. As the History Channel video above indicates, nerve agents are potent acetylcholinesterase inhibitors that utilize the same mechanism as organophosphate insecticides such as parathion. Conceptually, the effect of VX exposure is simple: wherever in the body acetylcholine acts as a neurotransmitter, nerve agents cause unregulated, chaotic activity. There are generally 3 such sites: muscarinic sites: connections between ner...

Linda Parton/shutterstock.com 4 out of 5 stars Interpretation of Workplace Tests for Cannabinoids. Kulig K. J Med Toxicol 2016 Sep 29 [Epub ahead of print] Abstract The interpretation of workplace urine drug tests for marijuana often becomes a point of contention in workman’s compensation cases or proceedings moving towards firing an employee. In may experience, the court or arbitrator not infrequently gets the science of these tests wrong. Such misinterpretation can be devastating for the employee who is at risk of losing his or her job and benefits. This concise review of the subject by Ken Kulig gets the science r...

Missing loperamide (Imodium) abuse can be a fatal mistake
3 out of 5 stars Epidemiologic Trends in Loperamide Abuse and Misuse. Vakkalanka JP et al. Ann Emerg Med 2016 Nov 4 [Epub ahead of print] Abstract This paper reviews loperamide exposures reported to the National Poison Data System  over the 6-year period from 2010 through 2015. Because of the well-recognized limitations involved in retrospective analysis of poison center data, there is not much clinically useful information revealed by their study. The authors did find — unsurprisingly — that reported exposures to loperamide went up from 2010 to 2015, increasing by 91%. As we’ve discus...

Does exposure to marijuana cause myocardial infarction?
2 out of 5 stars Prolonged cardiac arrest complicating a massive ST-segment elevation myocardial infarction associated with marijuana consumption. Orsini J et al. J Community Hosp Intern Med Perspect 2016 Sept 7;6(4):31695 Full Text The medical literature contains scattered, rare case reports and series describing myocardial infarction, acute coronary syndrome, and cardiac arrest associated with exposure to cannabis. (Extreme emphasis on the word “associated.”) This literature is limited by a number of crippling problems, including failure to screen completely for presence of other drugs, failure to collect com...

Abstract As mentioned here a number of times in the past, I find papers that abstract and collate data from computerized poison center registries frustrating and infuriating. They are invariably beset by multiple intractable limitations: incomplete and unreliable data, poor follow-up, unconfirmed assertions, reporting bias, mis-coding, etc etc.  Typically, extensive statistical analysis manipulations ar...

Alcoholic ketoacidosis: case report and review
3.5 out of 5 stars A Patient with Alcoholic Ketoacidosis and Profound Lactemia. Gerrity RS et al. J Emerg Med 2016 Oct;51:447-449. Abstract This is a very good short case-based review of alcoholic ketoacidosis (AKA), and well-worth the 5 – 10 minutes reading time. Some key points: Development of AKA requires increased (binge) alcohol intake along with starvation (decreased food and water intake.) The characteristic high anion gap metabolic acidosis with elevated lactate and β-hydroxybutyrate levels are the result of dehydration, decreased glycogen stores, increased reducing potential (increased NADH) ...

Must-read post: Why dialyze patients with chronic, asymptomatic hyperlithemia?
About a month ago I discussed a new state-of-the-art review of lithium poisoning, which I rated “four skulls” and called a near must-read. Now comes a superb post entitled “Why dialyze patients with chronic, asymptomatic hyperlithemia” from Josh Farkas from PulmCrit.org and emcrit.org. It is essential reading for all clinicians who deal with lithium poisoned patients. Dr. Farkas makes the following important points: A single lithium level, not correlated with the patient’s clinical condition or history, does not provide much useful information. The serum lithium level does not corre...

Must-read: ayahuasca in America
Ecuadorian ayahuasca shaman (Ammit Jack/shutterstock.com) In the current (Sept 12) issue of The New Yorker. Ariel Levy writes about the drug-fueled South American shamanistic ritual ayahuasca (or yagé,) and how its plants and practices are being imported to “hip” American areas such as Brooklyn and Silicon Valley. As TPR has explained before: Pharmacologically, ayahuasca is quite interesting. It is commonly made by macerating and boiling together parts of the plants Banisteriopsis caapi and Psychotria viridis. Neither of these plants, taken alone, has psychedelic properties. P. viridis doe...

State-of-the-art review of lithium poisoning: almost a must-read
4 out of 5 stars Lithium Poisoning: State of the Art.  Baird-Gunning J et al. J Intensive Care Med 2016 Aug 11 [Epub ahead of print] Abstract This is a very good paper, the best comprehensive review I can remember reading on lithium. It is up to date, with 78 references as recent as 2015. A major reason I liked it so much is that the authors are quire frank about how much we don’t know, and resist giving, for instance, mandates about when to start hemodialysis based on lithium levels. This is a temptation that the authors of the recent ExTRIP review  succumbed to. Interestingly, the two papers sha...

Elephant-tranquilizer (carfentanil)-tainted heroin showing up in Ohio
4 out of 5 stars Human Health Hazards of Veterinary Medications: Information for Emergency Departments. Lust EB et al. J Emerg Med 2011 Feb;40:198-207 Abstract Yesterday, Canadian police announced that, earlier in the summer, they had seized one kilogram of carfentanil contained in a package labelled “Printer Parts” shipped from China and addressed to a man in Calgary. Carfentanil is frequently, and accurately, referred to as an “elephant tranquilizer.” It is a fentanyl analog with a potency 10,000 times that of morphine (or 100 times that of fentanyl.) It is not approved for any medical i...
