A man in his 70s with weakness and syncope
DiscussionBrugada Type 1 ECG changes are associated with sudden cardiac death (SCD) and the occurrence of ventricular dysrhythmias. Patients that develop a Type 1 pattern without any precipitating or provoking factors have a risk of SCD of 0.5-0.8% per year. In patients that only have this pattern induced by a sodium channel blocking agent have a lower rate of SCD (0 - 0.35% per year)[1]. Drugs that have been associated with Brugada ECG patterns include tricyclic antidepressants, anesthetics, cocaine, methadone, antihistamines, electrolyte derangements, and even tramadol. [2]. Our patient had a Brugada Type ...

60 year old with vomiting, diarrhea, and syncope: is this Wellens? Is this type 2 MI?
 Written by Jesse McLaren, with edits/comments by Smith and Grauer A 60 year-old patient with diabetes and ESRD presented with 24 hours of vomiting, diarrhea, weakness and then a syncopal episode. Vitals: RR 18, sat 98%, HR 103, BP 124/71 and temp 38.0. Here ’s their ECG: is this Wellens?  There ’s borderline sinus tach, normal conduction, normal axis, and low voltages in the limb leads. The anterior leads have loss of R waves, mild convex ST segments and primary T wave inversion. In the context of QS waves, T wave inversion indicates old or subacute infarct, or reperfusion after signif icant infarc...

Vaccine associated myocarditis revisited with COVID-19 mRNA vaccines
When I had reviewed the topic of vaccine associated myocarditis for an editorial in the BMH Medical Journal in 2017, most of the cases were associated with small pox vaccination [1]. There were also reports of streptococcal pneumonia vaccine and influenza vaccine associated myocarditis. Autoimmune/inflammatory syndrome induced by adjuvants (ASIA) used in the vaccine were also implicated in some cases [2,3]. While the large scale vaccination for small pox in an attempt to prepare for potential bioterrorism was the association in 2003 [4], COVID-19 mRNA vaccines are currently in the limelight for vaccine induced myocarditis...

ECMO – Extracorporeal membrane oxygenation
ECMO – extracorporeal membrane oxygenation ECMO – Extracorporeal membrane oxygenation – has been in use for the past four decades to support persons who are unlikely to survive with mechanical ventilation. ECMO is used in both adult and pediatric practice, though in the initial years, use of ECMO was restricted to pediatric intensive care. The enthusiasm for use of ECMO in adults have been triggered by the beneficial effect noted during the last H1N1 influenza pandemic [1]. In contrast from cardiopulmonary bypass which is used for a short period during cardiac surgery, ECMO is used to support for a ...

Sotalol – class IIIa
Sotalol is a class IIIa antiarrhythmic agent as per the Modernized Classification of Cardiac Antiarrhythmic Drugs [1]. The class effect is voltage dependent K+ channel blocker. Specifically, it is a HERG channel –mediated rapid K+ current (IKr) blocker. It has additional action on beta 1 and beta 2 receptors. Sotalol increases refractory period and decreases tendency for reentry. The drug is useful in ventricular tachycardia without structural heart disease and in those with a remote myocardial infarction. It is also useful in atrial fibrillation with conduction through accessory pathway in WPW syndrome. ...

Role of RT-PCR in the diagnosis of Rheumatic fever/RHD
RT-PCR: Real-time polymerase chain reaction, a sophisticated gene sequence-based biochemical test. Thanks to corona, this complex medical investigation has become a household name. Jones proposed his criteria to diagnose acute rheumatic fever  in 1944, we still use it to diagnose with many modifications . Currently, AHA position statement – 2015 by Gewitz et all is  being followed. (Circulation 2015) From Braunwald textbook of cardiology. Apart from this, there is one catch . Even if the child fulfills Jone criteria, there needs to be evidence for preceding streptococcal sore throat, either by culture or antibody. ...

The Decline of Science In the Pandemic
Early in the pandemic there was a widespread belief that science would be our salvation. With the help of science we would be spared the worst consequences, such as occurred during the 1918 Spanish flu pandemic. A vaccine would arrive, reliably, after a few hard months of research, and in short order the problem would...Click here to continue reading...

Will the Uncertainties of COVID Science Resurrect Blogs?
Health news was popular before the pandemic. Now, almost all news is health news. It’s not only a rapt audience contributing to the deluge of COVID19 news. Two other factors: 1) the availability of preprint servers, digital archives where a scientific paper can be published without formal peer-review and 2) the attention economy. Attention is currency. Since the business model of both scientific journals, internet-based medical news sites and mainstream media is attention (citations, views), both groups are eager to publish all that is COVID. The slew of COVID papers are outpacing the normal vetting process. ...

Can We Discuss Flatten-the-Curve in COVID19? My Eight Assertions
Conclusion: I did not have a clear answer for my couple. But after thinking and writing about this question it seems that the most reasonable approach in this crisis is transparent information–no matter how stark. And, crucially, we must have space for public debate. I hate this virus. I wish it never came. But we can make it worse by avoiding hard discussions on tradeoffs, the limits of modern medicine and risk. JMM P.S. I am very interested in your rebuttals to any of my assertions but will block vitriol and politicized nonsense. Related posts: The Debacle of Hydroxychloroquine and Azithromycin for ...

Two ER Physicians Lend Their Opinion on Reopening the Economy
"Typically you quarantine the sick. When someone has measles you quarantine them. We ’ve never seen where we quarantine the healthy." "We’ve tested over 4 million… which gives us a 19.6% positive out of those who are tested for COVID-19. So if this is a typical extrapolation 328 million people times 19.6 is 64 million. That’s a significant amount of people with COVID; it’ s similar to the flu. If

Lonnie and Carrie ’ s Wheat Belly journey
“ Living the Wheat Belly and Undoctored lifestyle will not rid our lives of all adversity. But it can make you stronger, more optimistic, and resilient. Here is Lonnie and Carrie’s story: “One year ago today, my life changed in unthinkable ways. I discovered the Wheat Belly 10-Day Grain Detox book and read it during my kids’ spring break. I had dabbled in the ‘paleo’ diet world a bit over the last five years with inconsistent success and had some idea about how good I felt when eliminating grains… “But the protocols in this book seemed to go further then just diet, like addressin...

Some unconventional thoughts on coronavirus (COVID-19)
Public health authorities are advising frequent hand washing and social distancing, especially in the absence of confirmatory testing for COVID-19. I don’t have any wisdom to add to these practices. Vaccines are in the works, as are anti-viral drugs—nothing to add here, either. But let me reiterate what we do in the Wheat Belly and Undoctored lifestyles. In general, we do not treat diseases; we correct the factors that allow disease to emerge in the first place—a big difference. Take rheumatoid arthritis, for example. In conventional healthcare, the joint pain and swelling of rheumatoid arthritis are sup...
