MIA 2012: Nishijima DK et al. Immediate and delayed traumatic intracranial hemorrhage in patients with head trauma and preinjury warfarin or clopidogrel use. Ann Emerg Med. 2012 Jun;59(6):460-8.e1-7.
Bottom Line 1 CREST study: Patients presenting to the emergency room with blunt head trauma and preinjury warfarin or clopidogrel use have a high incidence of immediate intracranial hemorrhage, but a very low incidence delayed intracranial hemorrhage. Thus, if the initial head CT is negative, you should be able to discharge the patient home… [+]
MIA 2012: Hoffmann U et al. Coronary CT angiography versus standard evaluation in acute chest pain. N Engl J Med. 2012 Jul 26;367(4):299-308.
Bottom Line 1 ROMICAT-II study: Coronary CT angiography (CCTA) is a safe and faster diagnostic strategy than the standard evaluation of low-to-intermediate risk chest pain patients. CCTA, however, results in higher radiation exposure and more downstream testing. [+]
MIA 2012: Backes D, et al. Time-dependent test characteristics of head computed tomography in patients suspected of nontraumatic subarachnoid hemorrhage. Stroke. 2012 Aug;43(8):2115-9
Bottom Line 1 100% sensitive and specific if < 6 hours from headache onset 90% sensitive if after 6 hours A noncontrast head CT can effectively rule out atraumatic subarachnoid hemorrhage (aSAH) in patients who present with acute headache within six hours after ictus. Those who present outside this time window or present atypically for SAH (ie neck pain) require further workup, including a lumbar puncture. [+]
MIA 2012: Samuels-Kalow ME et al. Effective discharge communication in the emergency department. Ann Emerg Med. 2012 Aug;60(2):152-9
Bottom Line 1 This study tells us what we might already suspect: in the busy, hectic and loud Emergency Department, patients we discharge often lack comprehension of their hospital course. Additionally, they are frequently unable to report their diagnosis, a discharge plan or reasons they should return to the ED. [+]
MIA 2012: Pearce MS et al. Radiation exposure from CT scans in childhood and subsequent risk of leukaemia and brain tumours: a retrospective cohort study. Lancet. 2012 Aug 4;380(9840):499-505.
Bottom Line 1 Interpret this data how you will: Exposure to 2-3 CT scans of the head will triple the risk of brain tumors; 5-10 head CT scans will triple the risk of leukemia. In absolute terms, this translates into approximately 1 excess case of leukemia and 1 excess brain tumor per 10,000 patients. [+]
MIA 2012: IST-3 collaborative group et al. The benefits and harms of intravenous thrombolysis with recombinant tissue plasminogen activator within 6 h of acute ischaemic stroke (the third international stroke trial [IST-3]): a randomised controlled trial. Lancet. 2012 Jun 23;379(9834):2352-63.
Bottom Line 1 Giving tPA to stroke patients within 6 hrs of symptom onset does not improve mortality or independence at 6 months. However, patients might be a little “less disabled” while they are alive. Maybe. [+]

MIA 2012: Than M et al. 2-Hour accelerated diagnostic protocol to assess patients with chest pain symptoms using contemporary troponins as the only biomarker: the ADAPT trial. J Am Coll Cardiol. 2012 Jun 5;59(23):2091-8.
Bottom Line 1 For ED patients presenting with undifferentiated chest pain, a TIMI score of 0, together with a non-ischemic EKG, and a negative cTnI at 0 hours and 2 hours, can identify patients at very low-risk for having a major adverse cardiac event (MACE) in 30 days. [+]
Trick of the Trade: Ossification centers of the elbow
Fracture or a normal ossification center? This is a common question heard when viewing an xray of a pediatric elbow. How do you remember the timing of normal ossification centers? FYI, the xray images above are normal and have no fractures. [+]
Most Interesting Articles of 2012
The following compilation of the Most Interesting Articles in 2012 is the work of the EM residents at the Jacobi/Montefiore Emergency Medicine Residency Program. INTRODUCTION Standing at the intersection of patient care and academics, we Emergency Medicine residents have overwhelming expectations. We’re the ones dropping NG tubes, popping abscesses, and pushing stretchers, while also expected to remain up to date with current research and trends in our field. With all these lofty expectations, not to mention the ever-present requirement of sleep and caloric intake, how does a resident pick which papers to read in this sea of literature? [+]
