  • Episode 106. Toxic Alcohols with Thom Maciulewicz

    Show Notes from the Pharm So Hard Podcast with Dr. Thom MaciulewiczOverviewToxic alcohols like methanol, ethylene glycol, and isopropanol can cause severe metabolic acidosis and organ damage when ingested. This post summarizes key learnings from a podcast episode with toxicology expert Dr. Thom Maciulewicz on recognizing and managing toxic alcohol poisoning in the emergency setting.Key Topics Covered:

    • What are toxic alcohols?
    • Clinical signs and symptoms
    • Metabolic pathways
    • Diagnostic approach
    • Treatment principles
    • Specific agents – methanol, ethylene glycol, isopropanol
    • Importance of history taking
    • Using antidotes – fomepizole vs ethanol
    • Determining need for hemodialysis
    • Supportive care and monitoring
    • What are Toxic Alcohols?

      • Substances like methanol, ethylene glycol, isopropanol
      • Found in antifreeze, windshield fluid, solvents, fuels
      • NOT meant for human consumption
      • Metabolize into toxic intermediates
      • Clinical Presentation

        • CNS: Confusion, ataxia, coma
        • GI: Nausea, vomiting, pain
        • Ocular: Vision changes, blindness
        • Renal: Flank pain, kidney injury
        • Cardiac: Tachycardia, hypotension
        • Metabolic: High anion gap acidosis
        • Metabolic Pathways

          • Alcohol dehydrogenase converts parent alcohol into toxic aldehydes and acids
          • Methanol -> formaldehyde -> formic acid
          • Ethylene glycol -> metabolites like glycolic acid and oxalic acid
          • Isopropanol -> acetone
          • Organic acids cause high anion gap metabolic acidosis
          • Diagnostic Approach

            • Clinical suspicion from history and exam
            • High anion gap metabolic acidosis
            • Check osmolal gap, electrolytes, renal function
            • Test specific alcohol levels
            • Assess for end-organ damage like vision changes or kidney injury
            • Treatment Principles

              • IV fluids for hydration support
              • Bicarb for severe acidemia
              • Fomepizole or ethanol to block alcohol dehydrogenase
              • Hemodialysis to clear parent compound and metabolites
              • Manage end-organ effects – folinic acid for methanol, thiamine/pyridoxine for ethylene glycol
              • Close monitoring and supportive care
              • Specific AgentsMethanol

                • Formic acid causes blindness and basal ganglia damage
                • Bicarb, fomepizole, folinic acid
                • Hemodialysis often needed
                • Ethylene Glycol

                  • Oxalic acid crystals cause kidney injury
                  • Bicarb, fomepizole, thiamine, pyridoxine
                  • Hemodialysis if renal failure
                  • Isopropanol

                    • Acetone causes CNS depression
                    • Supportive care, address gastritis
                    • Hemodialysis rarely needed
                    • Key Takeaways

                      • Obtain thorough history – critical for identifying possible toxic alcohol exposure
                      • Have low threshold to start fomepizole empirically if concerned
                      • Tailor management to likely toxicant – methanol, ethylene glycol, isopropanol have important distinctions
                      • Determine need for hemodialysis since it is definitive treatment for significant poisoning
                      • Provide diligent monitoring and supportive care throughout course

                        EMPoweRx Home Study

                        This video is part of our Crazy Tox Case in the 2023 EMPoweRx Conference held in Austin, Texas. It was a requested topic of interest from many pharmacists and physicians in the emergency medicine world. In this video, we discuss the case study and provide insights into the treatment and management of a patient was Xylazine Toxicity. We hope that this video will be informative and helpful to those who are interested in emergency medicine.

                        https://youtu.be/3BxzFe09pag

                        Show Notes: Episode 102 – The Controversy of Cefdinir in UTIs

                        In this episode, we dive into the hot topic of using cefdinir, a third-generation oral cephalosporin antibiotic, in treating urinary tract infections (UTIs). Despite its low urine concentrations, cefdinir has shown clinical efficacy in treating UTIs, sparking a controversy that we explore in depth.

                        Key Topics:

                        Background on Cefdinir: We discuss the role of cefdinir in treating UTIs and why its use is controversial.

                        Review of Literature: We delve into several clinical trials and studies that have been conducted on the use of cefdinir for UTIs:
                        Cardinale et al: High efficacy and safety of cefdinir in UTI treatment.
                        Sader et al., 2005: Cefdinir showed high activity against common UTI pathogens.
                        Bonsu et al., 2006: High susceptibility of urinary pathogens to cefdinir.
                        Oishi et al., 2011: Prophylactic cefdinir could prevent recurrent UTIs in pediatric patients.
                        Leigh et al., 2000: Clinical cure rates and microbiologic response rates for cefdinir and cefaclor were statistically equivalent.
                        Kim et al., 2014: Cefdinir has low urine concentrations, which could potentially affect its efficacy in treating UTIs.
                        Davis et al., 2022: The study found that despite high resistance rates to some antibiotics in the U.S.-Mexico border region, cefdinir, along with amoxicillin/clavulanate, cefuroxime, and nitrofurantoin, showed lower resistance rates and could be effective for outpatient UTI treatment.

                        Clinical Pearls:
                        We share some key takeaways from the studies and discussions, including the role of cefazolin as the susceptibility surrogate for oral cephalosporins.

                        Discussion of Twitter Comments and Retweets: We discuss the results of a Twitter poll and the interesting discussions it sparked among healthcare professionals.

                        How do you tell a medical doctor?

                        Real doctors: *reluctant to state they are doctors in public/social forums*

                        Non-MD/DOs: *take every opportunity to say they are a doctor…* (chiropractors, naturopaths, pharmacists, apothecaries, charlatans…) https://t.co/OSVrViNZS1

                        EMPoweRx Conference

                        The Society for Academic Emergency Medicine is pleased to host EMPoweRx at SAEM23. The Emergency Medicine Pharmacotherapy with Resuscitation (EMPoweRx) Conference is an annual international, multidisciplinary conference dedicated to celebrating advancements in research and practice of emergency medicine pharmacotherapy.

                        While still new, emergency medicine pharmacists and pharmacotherapy has not had its own platform to present the latest evidence and issues facing emergency medicine pharmacy, until now. 

                        The EmpoweRx Conference, to be held in concurrently with the SAEM Annual Meeting, is designed by practicing emergency medicine pharmacists. The program will include a multidisciplinary and multispecialty speaker lineup to present on the latest in resuscitation, emergency medicine pharmacotherapy, and administrative issues that are unique to the emergency department.
