Emergency Medicine Cases

In this first installment of this Episode, Point of Care Ultrasound Pearls, Pitfalls & Controversies we have a panel of POCUS gurus, Dr. Greg Hall, Dr. Jordan Chenkin, Dr. Paul Hannam & Dr. Jason Fischer. They review the basic criteria for commonly used, practical Point of Care Ultrasound indications at the bedside and then dive into heated debate about specific pearls and pitfalls in Point of Care Ultrasound assessment of the patient with undifferentiated shortness of breath, undifferentiated shock, cardiac arrest and swollen leg. They discuss how best to interpret the massive body of literature for POCUS and when we can hang our hats on our Point of Care Ultrasound findings.

In the 2nd part of this episode on Stroke, Dabigitran & Intracranial Hemorrhage Dr. Walter Himmel & Dr. Dan Selchen tell us everything the ED doc needs to know about the oral direct thrombin inhibitor Dabigatran and how to reverse a Dabigatran ICH. The ED treatment of stroke is reviewed including best medications and a simple way to remember BP goals. They review the management of ICH including BP goals, indications for neurosurgery, the role of recombinant Factor Vlla, and how best to reverse Warfarin-associated and platelet-associated ICH.

Ep17 P1 StrokeDr. Walter Himmel, "the walking encyclopedia of Emergency Medicine" & Dr. Dan Selchen, the head of the stroke program at St. Micheal's Hospital in Toronto with 30+ years of experience as a stroke neurologist, update us on the literature regarding Emergency Stroke Controversies including the ABCD2 Score to predict Stroke after TIA, as well as the current thinking around the best carotid imaging for patients who have had a TIA. They then review the important findings of the key thrombolysis stroke trials & how we could incorporate these findings into our daily practice. Dr. Selchen reviews the key CT findings we should look for in stroke, & Dr. Himmel takes us through how to manage the dreaded complication of ICH post thrombolysis. This episode is super controversial - so please 'speak your mind' at the bottom of the page.

Ep16 MonoarthritisDr. Joel Yaphe, University of Toronto's Emergency Medicine Residency Program Director and Dr. Indy Ghosh discuss the difficult diagnostic dilemmas when faced with a patient with acute monoarthritis. They review how to distinguish clinically between septic arthritis and gout and which aspects of the presentation and work-up are the most reliable in risk stratifying patients. The key differential diagnosis of Acute Polyarthritis can be even more of a challenge, but fear not: by then end of this podcast and post you will be able to recognize the key diagnoses, how to work them up, and who needs consultation.

Septic Arthritis is often at the top of our differential for acute monoarthritis. Dr. Joel Yaphe tells his Best Case Ever of a patient with septic arthritis as a bonus to Episode 16: Acute Monoarthritis. In the related episode Dr. Yaphe and Dr. Indy Ghosh discuss such questions as: What are the most important risk factors for septic arthritis? What are the most predictive signs and symptoms of septic arthritis? How does serum WBC, ESR and CRP contribute to the probability of septic arthritis? Should we still be performing arthrocenteses on patient's with overlying cellulitis? with an INR of 6? How can you tell the difference between septic bursitis and septic arthritis and how are they managed differently? What does the literature tell us about how useful the synovial fluid tests are in ruling in or ruling out septic arthritis? What is the role of bedside ultrasound in septic arthritis? Is there a role for steroid therapy in septic arthritis? When would you consider oral NSAIDs vs oral prednisone vs intra-articular methylprednisolone for the treatment of Gout? Is there a role for colchicine in the ED treatment of Gout? What is acute calcific arthritis of hydroxyapatite disease and why is it important for ED docs to know about? What is the most common cause of dermatitis-arthritis? How can one distinguish Reactive Arthritis from Septic Arthritis clinically, and how do their work-ups differ? Is there a role for antibiotics in Reactive Arthritis? How does gonococcal arthritis present compared with nongonococcal septic arthritis? and many more.....

In Part 2 of this Episode on Acute Coronary Syndromes Risk Stratification & Management, the evidence for various medications for ACS, from supplemental oxygen to thrombolytics are debated, and decision making around reperfusion therapy for STEMI as well as NSTEMI are discussed. Finally, there is a discussion on risk stratification of low risk chest pain patients and all it's attendant challenges as well as disposition and follow-up decisions. Dr. Eric Letovsky, the Head of the CCFP(EM) Program at the University of Toronto, Dr. Mark Mensour & Dr. Neil Fam, an interventional cardiologist answer questions like: What is the danger of high flow oxygen in the setting of ACS? When, if ever, should we be using IV B-blockers in AMI patients? How can you predict, in the ED, who might go on to have an urgent CABG, in which case Clopidogrel is contra-indicated? Which anticoagulant is best for unstable angina, NSTEMI and STEMI - unfractionated heparin (UFH), low molecular weight heparin (LMWH), or fonduparinux? Is there currenly any role for Glycoprotein 2b3a Inhibitors in ACS in the ED? When is thrombolysis better than PCI for STEMI? When should we consider facilitated angioplasty and rescue angioplasty? Which low risk chest pain patients require an early stress test? CT coronary angiography? Stress Echo? Admission to a Coronary Decision Unit (CDU)? and many more.......

In Part 1 of this Episode on Acute Coronary Syndromes Risk Stratification Dr. Eric Letovksy, Dr. Mark Mensour and Dr. Neil Fam discuss common pearls and pitfalls in assessing the patient who presents to the ED with chest pain. They review atypical presentations to look out for, what the literature says about the value of traditional and non-traditional cardiac risk factors, the diagnostic utility of recent cardiac testing, and which patients in the ED should have a cardiac work-up. Finally, in the ED work up of Acute Coronary Syndromes Risk Stratification, they highlight some valuable key points in ECG interpretation and how best to use and interpret cardiac biomarkers like troponin. Drs. Letovksy, Mensour & Fam address questions like: How useful are the traditional cardiac risk factors in predicting ACS in the ED? How does a negative recent treadmill stress test, nuclear stress test or angiogram effect the pre-test probability of ACS in the ED? What does recent evidence tell us about the assumption that patients presenting with chest pain and a presumed new LBBB will rule in for MI and require re-perfusion therapy? How can we diagnose MI in the patient with a ventricular pacemaker? What is the difference between Troponin I and Troponin T from a practical clinical perspective? Is one Troponin ever good enough to rule out MI in the patient with a normal ECG? Should we be using a 2hr delta troponin protocol? How will the new ultra-sensitive Troponins change our practice? and many more.....

In anticipation of Episode 15, 'Acute Coronary Syndromes' with Dr. Eric Letovsky, Dr. Mark Mensour and Dr. Neil Fam, we present here, Dr. Helman's 'Best Case Ever' of an ACS patient. In Episode 15: 'Acute Coronary Syndromes', Drs. Fam, Mensour , Letovsky and Helman discuss questions like: How does a recent negative stress test or angiogram effect the pre-test probability of ACS in the ED? What does recent evidence tell us about the assumption that patients presenting with chest pain and a presumed new LBBB will rule in for MI and require reperfusion therapy?

In association with Episode 14, 'Headache Pearls & Pitfalls' with Dr. Anil Chopra and Dr. Stella Yiu, we present here, the third of our new 5 minute 'Best Case Ever' series. In Episode 14: Headache Pearls & Pitfalls, which has just been released, Dr. Chopra and Dr. Yiu answer questions like: With the ever improving resolution of CT, should we still be doing LP after negative plain CT head for all our thunderclap headache patients? How can we best minimize the chance of post-LP headache? What evidenced-based treatments can we initiate in the ED for our SAH patients that will improve outcomes?
