Severe reactions to “Spice” on rise, some associated with drug MAB-CHMINACA
AB-CHMINACA 3 out of 5 stars In vitro and in vivo human metabolism of the synthetic cannabinoid AB-CHMINACA Erratico C et al. Drug Test Analysis 2015 Apr 12 [Epub ahead of print] Abstract The New York Times reported today on the recent dramatic increase in emergency department visits related to use of synthetic cannabinoids (call colloquially, but somewhat inaccurately, “Spice”). This phenomenon has been seen in many states, especially Mississippi, Pennsylvania, and New York. According to reports, patients often present with agitation, delirium, and hallucinations. Medical complications have included rhabdo...

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)

Proton pump inhibitors increase risk of acute kidney injury
3 out of 5 stars Proton pump inhibitors and the risk of acute kidney injury in older patients: a population-based cohort study. Antoniou T et al. CMAJ Open 2015;Apr;3:E166-E171. Full Text Previous studies have suggested that use of proton pump inhibitors (PPIs) increases risk of acute interstitial nephritis, especially in elderly patients. Using information from several large computerized databases containing medical information about patients in Ontario, Canada, the authors carried out a population-based cohort study of patients in Ontario aged 66 years and older who were newly prescribed PPIs, compared with match...

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.

Do medical toxicologists use physostigmine to treat anticholinergic toxidrome?
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 ...

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...

Death after injecting alpha-PVP
3 out of 5 stars Death due to intravenous use of α-pyrrolidinopentiophenone. Sellors K et al. Med J Aust 2014 Nov 17;201:601-3. Full Text α-pyrrolidinopentiophenone (α-PVP) is a synthetic cathinone stimulant with structural similarities to MDPV. Like MDPV, α-PVP contains a pyrrolidine ring, a 5-sided nitrogen-containing component that enables the molecule to effectively block reuptake of dopamine and norepinephrine, with much weaker effects at the serotonin transporter. This dramatic case report describes a 44-year-old man who injected a product labelled “Smokin’ Slurries Scrubba” (α-PVP) intrave...
