Podcast 748: Botulism

Podcast 748: Botulism
Contributor: Nick Hatch, MD Educational Pearls: Botulism requires a prompt clinical diagnosis as lab results can take about 5 days to return Whale blubber, honey, home fermented foods, homemade wine (especially the wine made in prison), and improperly stored canned food can all contain the toxin The botulinum toxin is create by a Clostridium botulinum that is prevalent on our food and in the soil, but the toxin is readily degraded with heat and light Blocks release of acetylcholine at the neuromuscular junction preventing release of neurotransmitter and therefore the propagation of an electrical nerve potential Descending paralysis, often first including bulbar muscles, and anticholinergic symptoms can be present on exam Infantile botulism, classically seen as floppy baby syndrome, occurs up to a week after ingestion, because the infant GI tract is not acidic enough to deactivate the toxin Antitoxin is available to neutralize the botulism toxin present, but it cannot prevent the already established symptoms References Jeffery IA, Karim S. Botulism. [Updated 2021 Jul 19]. In: StatPearls [Internet]. Treasure Island (FL): StatPearls Publishing; 2022 Jan-.

Podcast 747: Food Impaction
Contributor: Ricky Dhaliwal, MD Educational Pearls: Esophageal food impaction can be managed in the ED prior to calling GI for endoscopy Coca-cola, glucagon, benzodiazepines, calcium channel blockers, and dissolved nitroglycerin are all options to try For pediatric patients, weighted bougies can be used under sedation to attempt retrieval of the food bolus Always evaluate airway status, especially if the patient cannot maintain secretions References Long B, Koyfman A, Gottlieb M.

Podcast 746: Elderly Head Trauma on Anticoagulation
Contributor: Aaron Lessen, MD Educational Pearls: Biggest study to date examined new protocol for repeat head CT in anticoagulated elderly patients with head trauma and an initial negative head CT 0.5%-6% of patients in this category will get a delayed ICH and this can occur up to a week out from initial injury 18% of the study group had an ICH on initial head CT, but the rest who had negative head CT initially received a repeat head CT at 6 hours 0.9% had a bleed identified on repeat head CT 6 hours after initial imaging, but of this group no one had an intervention for this bleed Suggests repeat head CT may not be needed and that good counseling for return precautions and discharge is a reasonable disposition in caring for these patients Supratherapeutic INR was a risk factor for delayed bleed, so they should be treated as a higher risk group of patients References Borst J, Godat LN, Berndtson AE, Kobayashi L, Doucet JJ, Costantini TW. Repeat head computed tomography for anticoagulated patients with an initial negative scan is not cost-effective.

Podcast 745: Nitrous-Induced B12 Deficiency
01/10/2022
Podcast 745: Nitrous-Induced B12 Deficiency
Contributor: Alicia Oberle, MD Educational Pearls: Nitrous oxide (N2O) can cause a vitamin B12 deficiency in patients after regular use N2O is used in procedural sedation but also as a popular recreational drug N2O binds and inactivate B12 in the body, therefore decreasing usable supply Lack of B12, which is essential for myelinating nerves, can lead to subacute combined degeneration of the spinal cord Presentation may include paresthesias, ataxia, gait changes, or bilateral lower extremity motor weakness B12 can be normal on labs, as the B12 is present but inactivated Treatment is daily B12 injections and oral supplementation References Stockton L, Simonsen C, Seago S. Nitrous oxide-induced vitamin B12 deficiency. Proc (Bayl Univ Med Cent). 2017;30(2):171-172. doi:10.1080/08998280.2017.11929571 Samia AM, Nenow J, Price D.

Podcast 744: Glucagon for Beta Blocker Toxicity
Educational Pearls: Glucagon can be used to treat hypoglycemia and esophageal foreign body, but it can also be used in beta-blocker toxicity to bypass cardiac beta-blockade The superior option for treating bradycardia due to beta-blocker toxicity is glucagon Glucagon has decreased efficacy in patients with heart failure, so increased doses up to 10 mg might be required in the event of beta-blocker toxicity References Khalid MM, Galuska MA, Hamilton RJ.

Podcast 743: Rust Rings
Contributor: Jared Scott, MD Educational Pearls: A rust ring can occur after a metallic foreign body is left in the eye for a prolonged period of time Issues occur when the rust ring is left as it can epithelialize and become a permanent spot in the patient’s vision An eye burr or Alger brush can help to gouge out the rust ring in the emergency setting These tools have a failsafe mechanism to prevent the eye burr from going through layers past the cornea (though this does not work if the foreign body is already through the cornea) Referral to ophthalmology, antibiotic drops, and dilating drops are recommended options upon discharge Complications include poor wound healing, scarring, and infection References Camodeca AJ, Anderson EP.

Podcast 742: Pulse Check During CPR
12/29/2021
Podcast 742: Pulse Check During CPR
Contributor: Aaron Lessen, MD Educational Pearls: Pulse checks are necessary during CPR to check for return of spontaneous circulation (ROSC) Previous studies have shown that assessing ROSC with palpating for pulse are not a very consistent Study compared palpating pulses at carotid/femoral artery versus a newly contrived gold standard for pulse checks The gold standard used was an increase in end tidal CO2 + cardiac activity on ultrasound + perfusing rhythm on ECG Carotid artery palpation was the best location to confirm pulse during pulse check, although femoral artery palpation Carotid artery palpation was 92% accurate versus 82% accuracy with femoral pulse check Regardless of chosen site, remember 10 seconds is the maximum amount of time for a pulse check before resuming CPR References Yılmaz G, Bol O. Comparison of femoral and carotid arteries in terms of pulse check in cardiopulmonary resuscitation: A prospective observational study.

Podcast 732: Organophosphate Toxicity
Educational Pearls: Organophosphates affect the cholinergic system by inhibiting acetylcholinesterase affecting muscarinic and nicotinic receptors Symptoms include lacrimation, salivation, bronchoconstriction, blurred vision, bradycardia, bronchorrhea, emesis, and diarrhea Initially, the patient should be decontaminated to prevent further organophosphate exposure Treatment consists of atropine every 5 minutes, 1-3 mg to start and doubling the dose each time it is given until reversal of symptoms is seen Atropine only works on muscarinic receptors, so nicotinic receptor activation continues despite atropine administration resulting in muscle contractions and eventually respiratory arrest Pralidoxime (2-PAM) should also be given to prevent the nicotinic effects and maturation of the organophosphate-acetylcholinesterase complex References Robb EL, Baker MB.

Podcast 724: Ivermectin Overdose
Contributor: Don Stader, MD Educational Pearls: Ivermectin is a Nobel-Prize winning antiparasitic used to treat filariasis and onchocerciasis Ivermectin is receiving press due to a scientific study examining ivermectin on COVID-19 viral replication in vitro, but the dosages needed for this effect were much higher than is safe for human use Ivermectin has since been studied in humans with no evidence suggesting it is a viable treatment for COVID-19 Ivermectin is a neurotoxin but at normal levels it does not cross the blood-brain barrier Ivermectin toxicity can include altered mental status, seizures, coma, tachycardia, hypotension, nausea, vomiting and diarrhea Treatment of suspected ivermectin overdose is predominately supportive References Caly L., Druce J.D., Catton M.G., Jans D.A., Wagstaff K.M.
