Contributor: Jared Scott, MD Educational Pearls: Cholera has been responsible for 6 previous global pandemics and currently the world is in the seventh pandemic of cholera, ongoing since 1961. Cholera originated in the Ganges Delta of India and spread worldwide but largely is unseen in the US and other developed countries due to water sanitation Cholera is a bacterial illness that is water borne and causes severe diarrhea Estimates say that there are 1.3-4 million cases annually and up to 143,00...

Host : Elizabeth Esty, MD. At this point, with so many of the studies we’ve digested exploring correlations, associations, observational studies and anecdotal reports and speculation, we could subtitle the show: what we don’t know about COVID. And so, today, we’ll look at what we don’t know about Vitamin D and COVID. There have been a number of studies and a fair amount of media coverage in recent weeks that look at a possible link between low Vitamin D levels and severity of COVID. Vitamin D pl...

Contributor: Nick Hatch, MD Educational Pearls: An AC (acromioclavicular joint) separation in the shoulder is a common traumatic injury XRs can help rule out other injuries as well as help with grading the injury There are six different grades for AC separations: Grade I: is stretching of the AC ligament without disruption or displacement of the clavicle and recovers with time. Grade II: is partial tearing of the AC ligament with some displacement but will also heal with time. Grade III: is a fu...

Host : Elizabeth Esty, MD. Smoking is known to increase both susceptibility and severity of all manner of colds and pneumonias, so you’d think the world's 1.1 billion smokers would be at risk in this pandemic of what at first seemed to be a just a respiratory virus. What’s more, tobacco smoking increases risk for COPD, diabetes and coronary disease, so it may increase risk for more severe COVID indirectly. So it’s remarkable that preliminary evidence suggests that smokers may be less likely to b...

Contributor: Don Stader, MD Educational Pearls: Buprenorphine has been shown to decrease morbidity and mortality in opioid use disorder Buprenorphine used in naloxone-induced withdrawals can displace naloxone at opioid receptors, leading to reduced withdrawal symptoms and lessen the chance of using after discharge Patients in acute withdrawal due to naloxone after an overdose should be given Buprenorphine. Data shows that withholding Buprenorphine leads to increased mortality rates of 5% within ...

In the US, few people receive vaccination for tuberculosis (TB), a disease that hasn’t been a major killer here for many decades. But while we in the US mostly experience TB as a relatively rare but real threat in its multidrug resistant form, particularly in pts with HIV--or in Victorian novels--TB still kills 2 million people a year. There is a vaccine for TB, a live attenuated vaccine called BCG for Bacille Calmette-Guerin. In fact it’s the most widely used vaccine on earth, and an estimated ...

Contributor: Dylan Luyten, MD Educational Pearls Acidosis can be caused by a respiratory, metabolic, or mixed source A respiratory acidosis will have a low serum pH and elevated bicarbonate if it’s chronic, but most importantly end tidal CO2 or arterial CO2 will be high. With a metabolic acidosis we expect to see a low serum pH and low serum bicarbonate. Once it’s determined a patient is in a metabolic acidosis, we need to determine if it’s an elevated anion gap or normal anion gap acidosis. Ani...

Contributor: Don Stader, MD Educational Pearls: Acute respiratory distress syndrome (ARDS) is a catch all term for when lung injury leads to fluid collection in the air spaces of the lungs Ventilatory management in ARDS patients involves lower FiO2 and PEEP than other patients and relies on lung protective ventilation strategies to prevent barotrauma Proning these patients has also been utilized with the goal of matching V/Q, or getting good blood flow to areas of the lung which are well ventila...

Last week we looked at neurologic presentations of COVID-19; this week we’ll look more closely at strokes in young people with COVID. A letter published 2 days ago in the NEJM with lead author Thomas Oxley, the Neuro ICU director at Mt Sinai, presents five case studies of relatively young patients who had strokes at home and presented to Mt Sinai between 23 March and 7 April . In pre-COVID days, Mt Sinai saw on about 3 patients under the age of 50 with strokes per month, so 5 in 2 weeks represen...

Contributor: Don Stader, MD Educational Pearls: COVID-19 is diagnosed with a nasopharyngeal swab (q-tip). This unfortunately can be painful, but if the swab doesn’t go deep into the nasal cavity the sample can be inadequate leading to false negatives (missed infections). The sensitivity of the COVID-19 RT PCR test is low, ranging from 66-80% in various studies. Another study has shown 23% of patients who initially tested negative but had COVID-19 symptoms will test positive when re-tested. So te...

Contributor: Don Stader, MD Educational Pearls: When do we give antiplatelet drugs or anti-coagulation drugs? Arterial issues get antiplatelet therapy Venous issues, or slow flow states, get anticoagulation therapy. High flow areas (arteries) are more prone to platelet clotting while the venous system is more prone to allowing blockages caused by coagulation factors. The main side effect with antiplatelet and anticoagulants is bleeding. Typically antiplatelet drugs cause more bleeding issues bec...

Accumulating clinical evidence suggests that many patients with COVID have neurological symptoms a nd that some may even present with neurologic manifestations of the disease. Most COVID patients have a cough, respiratory distress, and while clinicians often speak about how similar the presentations of patients with respiratory COVID are, it’s worth looking at the possibility that COVID has atypical presentations, too. There’s very good evidence that coronaviruses can infect all sorts of human c...
