Unlabeled amphetamine isomer in sports supplement “probably” caused hemorrhagic stroke
3.5 out of 5 stars Hemorrhagic Stroke Probably Caused by Exercise Combined With a Sports Supplement Containing β-Methylphenylethylamine (BMPEA): A Case Report. Cohen P et al. Ann Intern Med 2015 May 12 [Epub ahead of print] Reference Last month, the FDA sent letters to 5 companies that manufacture so-called “dietary” or “sports” supplements, warning them that their products were mislabeled because they contained an unlisted ingredient. That ingredient, β-methylphenylethylamine (BMPEA), is an isomer of amphetamine. Although the effects of BMPEA in humans have not been well studied, it has been ...

ED sedation with droperidol is relatively safe and effective
This study has shown that droperidol is relatively safe and effective for the management of violent and aggressive patients in the ED and that there was no increased risk of QT prolongation and torsades de points according to a large cohort of cases.” The “Editor’s Capsule Summary” that accompanies the article is even more emphatic*: How this is relevant to clinical practice Droperidol is safe even with the high doses used in this study. The authors note that the study does not rule out that droperidol may be associated with rare cases of torsades. But the agitated, delirious ED patient may be a dan...

Lipid rescue therapy and ECMO in the poisoned patient — can they be used together?
3 out of 5 stars What are the adverse effects associated with the combined use of intravenous lipid emulsion and extracorporeal membrane oxygenation in the poisoned patient? Lee HM et al. Clin Toxicol 2015;53:145-150. Abstract Veno-arterial extracorporeal membrane oxygenation (VA-ECMO) is often used in the neonatal and pediatric intensive care units on children who are also receiving intravenous lipid emulsion (LE) for nutritional support. Complications reported in patients receiving both interventions include lipid agglutination, clogging, occurrence of blood clots, and cracking of parts of the ECMO circuit. There is inc...

Even Dr. Oz can’t rebut John Oliver
Dr. Oz’s rebuttal yesterday to the letter from ten self-described “distinguished physicians” who demanded that Columbia Medical School cancel his faculty appointment was absolutely brilliant — recasting the narrative from the selling of snake oil to standing up for free speech and against the juggernaut agricultural-industrial complex. But there’s no rebuttal to John Oliver. See also Michael Specter’s New Yorker blog post on this issue, as well as his superb profile of Dr. Oz in the magazine. (Source: The Poison Review)

Poisonous birds: what’s new
3 out of 5 stars Poisonous birds: A timely review. Ligabue-Braun R, Carlini CR. Toxicon 2015 Mar 31;99:102-108. Abstract It was just over two decades ago that Dumbacher et al published their landmark paper describing the presence of the alkaloid batrachotoxin (BTX, “frog poison”) in the skin and feathers of three species of Pitohui bird in New Guinea. This toxin binds to voltage-gated sodium channels maintaining them in the open position. This action causes depolarization of nerves and myocardial cells. This may serve the bird by acting as a “chemical defense” against large predators, or as a ...

Factors associated with emergency department opioid-related adverse drug events
This study has a number of limitations, which the authors discuss candidly. For example, the study design would miss capturing a patient who received an opioid in the emergency department, was admitted, and died from respiratory depression on the floor. Nevertheless, this is a valuable reminder of the patient, provider, and systems factors that should raise red flags of caution when administering opioids in the emergency department. Worth reading.

“Flakka”: one of the most bizarre drugs yet
South Florida has recently seen a number of cases associated (at least by history) by exposure to a street drug called “Flakka”: In Lake Worth, a naked man brandishing a handgun stood on the roof of an apartment building, shouting “I feel delusional, and I’m hallucinating.” In Fort Lauderdale, a man tried to kick in the door of the local police station because he thought he was being chased by automobile seeking to do him harm. And 2 weeks ago, also in Fort Lauderdale, a man impaled himself on a spiked fence around a police station apparently in thrall to a paranoid delusion: It is no wonder ...

ACEP Toxicology Section Antidote App (free)
This simple but very useful app, from the Toxicology Section of the American College of Emergency Physicians, provides basic information about uses and dosing of basic antidotes used in toxicology. Version 1.1 covers approximately 50 different antidotes from A (acetylcysteine) to T (thiamine). Of course, clinical judgment is still required when considering these treatments, and most situations requiring use of the antidotes listed would justify consultation with a poison center. For example, one of the potential indications listed for hyperbaric oxygen (HBO) therapy in carbon monoxide (CO) poisoning is myocardial ischemia....

Intravenous lipid emulsion in oral overdoses: what is the optimal dosing?
This article is an attempt to arrive at a rational dosing schedule for LE in oral overdoses.

2.5 out of 5 stars The Use of Physostigmine by Toxicologists in Anticholinergic Toxicity. Watkins JW et al. J Med Toxicol 2014 Dec 16 [Epub ahead of print] Abstract Physostigmine is a carbamate that reversibly inhibits acetylcholinesterase, the enzyme that breaks down acetylcholine (ACh). By so doing, it increases the levels of ACh in synapses, serving as an antidote for drugs and agents causing anticholinergic syndrome. Unlike neostigmine, physostigmine crossed the blood-brain-barrier and has both peripheral and central effects. Decades ago, physostigmine was routinely used with some frequency to treat overdose with ...

Evidence does not support use of long-term opioid therapy for chronic pain
3.5 out of 5 stars The Effectivenss and Risks of Long-Term Opioid Therapy for Chronic Pain: A Systematic Review for a National Institutes of Health Pathways to Prevention Workshop. Chou R et al.

Tox Tunes #92: Born in Chicago (Paul Butterfield)
This is my favorite live version of Paul Butterfield’s blues classic “Born in Chicago” (written by Nick Gravenites.) It also features Rick Danko on bass and Blondie Chaplin on guitar. Although this visceral and gritty song does not specifically mention drugs, they are certainly alluded to in the lyrics: Well, my first friend went down When I was 17 year old Well, my first friend went down When I was 17 years old Well, there’s one thing I can say about that boy He gotta go Well, my second friend went down When I was 21 years of age Well, my second friend went down When I was 21 years of age Well, th...

Tox in the news: 72 die in Mozambique from poisoned beer
Mozambique In a very strange story that’s been developing all week, the Washington Post reported that at least 72 people died in Mozambique after consuming poisoned beer offered at a funeral gathering. Details are scarce and the poison (or poisons) has not yet been identified, but a limited clinical scenario can be gleaned from reading news coverage. Apparently, the funeral was an all-day affair. The beer was brewed in and served from a 210 liter container. People who drank the beer only in the morning were not affected. However, those who had the beer in the afternoon were sick by the next morning, with diarrhea ...

Whole bowel irrigation? Don’t just do something, stand there!
3.5 out of 5 stars Position paper update: Whole bowel irrigation for gastrointestinal decontamination of overdose patients. Thanacoody R et al. Clin Toxicol 2015 Jan;53:5-12.

Hallucinogenic stimulant PMMA found in “Superman” pills that killed 4 in Britain
The Guardian (U.K.) reported yesterday that the deaths of 4 men in Britain over the holidays were associated with a drug — purported to be MDMA (ecstasy) — that actually contained the hallucinogenic stimulant PMMA, a far more dangerous drug. The deaths all seemed to be related to a 5-sided pill that reproduced the famous Superman logo. PMMA is related to PMA, a drug so lethal it has been marketed under the name “Dr. Death.” Some data indicates that PMMA (para-methoxymethamphetamine) is metabolized to PMA (para-methamphetamine.) Both PMA and PMMA cause increased release of serotonin along with decreased re...
