  2. Breaking Bad News (hemeonc, psych)
    1. Several mnemonics are available to guide an approach to Breaking Bad News
  3. Type I Diabetes Mellitus (endo, dm)
    1. Early aggressive Insulin management with A1C maintained<7% reduces morbidity and mortality rates, sustained for decades
    2. Self-monitoring of Blood Glucose is associated with better Glucose control
    3. Insulin Pump is selected by more than half of type I diabetics, but multiple daily basal and bolus injections offers similar efficacy
  4. Connective Tissue Disease (diffuse, rheum)
    1. Limit rheumatologic testing (e.g. ANA, RF) to cases of higher clinical suspicion given the high rate of positives in the unaffected population
    2. When higher suspicion for Connective Tissue Disease, only obtain specific Antibody testing when ANA is positive
  5. Chronic Nonallergic Rhinitis (ent, nose)
    1. Reclassification of non-allergic non-Infectious Rhinitis of which subtypes include Vasomotor Rhinitis and Nonallergic Rhinitis with Eosinophilia
    2. Rhinorrhea predominant symptoms are treated with intranasal Atrovent first
    3. Congestion predominant symptoms are treated with Intranasal Corticosteroids and/or intranasal Antihistamines
  6. Congestive Heart Failure Exacerbation Management (cv, chf, er)
    1. Consider causes of acute CHF decompensation (e.g. medication or dietary non-compliance, ACS, arrhythmia)
    2. Start with NIPPV and Nitroglycerin in hypertensive CHF, and consider ACE Inhibitor, Diuretics
    3. History, exam and Bedside Ultrasound are typically more effective as diagnostic tools than BNP
    4. Consider Ottawa Heart Failure Risk Score to risk stratify very low risk patients to discharge (most will require admission)
  7. Fever in the Returning Traveler (id, fever, travel)
    1. Careful history of travel timing, regions, exposures is critical to identifying likely causes
    2. Be vigilant and consider personal protection, when evaluating a febrile traveler who may need isolation (e.g. hemorrhagic fever, MERS)
    3. Excluding Malaria is key, even in mild illness, even in those who took chemoprophylaxis
  8. Pericarditis (cv, Pericardium)
    1. Children with significant Pericarditis (large Pericardial Effusion, Myocarditis) may present with subtle findings (e.g. Sinus Tachycardia, Puffy Eyelids)
  9. Hypokalemia (renal, Potassium)
    1. Obtain EKG for Potassium <3.0 mEq/L and observe for QTc Prolongation
    2. For every Serum Potassium drop of 0.3 mEq/L, total body Potassium deficit increases 100 mEq
    3. Consider empiric Magnesium Replacement with Potassium Replacement (e.g. 400-500 mg twice daily for 3 days)
  10. Chronic Kidney Disease (renal, failure)
    1. CKD patients die of Coronary Artery Disease. Prescribe a Statin, ACE Inhibitor, Aspirin
    2. Significant medication adjustments start at Creatinine Clearance <30 mg/dl

  12. Flumist (id, immunize, virus)
    1. In 2018, Flumist is once again an option for influenza Vaccination, albeit likely still less effective than other influenza Vaccination options
    2. Consider Flumist in healthy, non-pregnant patient aged 2 to 49 years who would otherwise refuse Influenza Vaccine
  13. Migraine Prophylaxis (neuro, Headache)
    1. Erenumab (Aimovig) is a new, expensive ($7000/year) biologic, monthly SQ injection for Migraine Prophylaxis
    2. Indicated when other first-line Migraine Prophylaxis options have been exhausted
  14. Sunburn (derm, environ)
    1. Treat as minor Burn Injury with cool compresses and inert Skin Lubricants (e.g. eucerin)

  16. Methotrexate (rheum, ra, dmaard)
    1. MethotrexateOverdose or toxicity is potentially lethal if not treated
    2. Optimize urine output and alkalinize the urine
    3. Administer folinic acid or Leucovorin to bypass Methotrexate induced blockade of dihydrofolate reductase and supply active Folate
    4. Administer Glucarpidase (if available), an expensive enzyme that breaks down Methotrexate (and unfortunately Leuocovorin)
  17. Serum Magnesium (renal, Magnesium)
    1. Serum Magnesium represents only 1 to 1.5% of total body Magnesium (of which only 50% is active, ionized)
    2. Magnesium levels tend to vary widely (e.g. with respiration) and single values are unlikely to be useful
    3. Serum Potassium tends to be a surrogate marker for Serum Magnesium
    4. Hypokalemia is typically accompanied by Hypomagnesemia (consider empiric Magnesium Replacement at the time of Potassium Replacement)
  18. Provider Burnout (manage, psych)
    1. Acute stress may us more effective in emergencies, but chronic stress is maladaptive and leads to burnout
    2. Consider self actualization pyramid of needs (physiologic, safety, love and belonging and self esteem)
    3. Maintain Exercise, Healthy Diet, adequate sleep, and get together with colleagues, family and friends
  19. Peripheral IV Access (er, procedure)
    1. Two additional techniques for difficult Peripheral IV Access
    2. Tourniquet Infusion Technique uses an already placed small IV to infuse 100 cc NS and a Tourniquet above the elbow results in Forearm venous engorgement for second IV
    3. Central Vein Placement of peripheral IV targets an internal Jugular Vein under Ultrasound guidance with a peripheral IV (48 mm long is ideal if available)

    1. Oxycontin true duration of action approaches 6 hours (instead of 12 hours) in many patients
    2. Oxycontin was released as MS Contin (8 hour duration) patent was expiring
    3. The exaggerated duration may add to misuse and abuse of Opioids
  14. Acute Pain Management (pharm, Analgesic)
    1. Limit Opioids for acute pain to 3 days in most patients (7 days in nearly all patients)
    2. Avoid non-cancer Chronic Opioids
  15. Ketamine (surgery, pharm)
    1. Ketamine is often used as a very effective and safe pre-hospital Chemical Restraint
    2. Ketamine at high dose (4-5 mg/kg) results in GCS 3, but typically maintained respiratory drive (GCS-3K)
    3. Many providers prematurely intubate based on ED arrival GCS 3 (despite Ketamine induced)
