Things that bug me – telling me normal (CBC, BMP)
Dr. Rabih Geha’s excellent post on Closler – Every Piece of Data Matters – has stimulated much thought. He makes one important point that I would like to expand.
My mind finds it much harder to attach diagnostic significance to pertinent negatives. Even if their impact on a diagnostic hypothesis is equal, I find that a positive test result sways my reasoning more so than an equally impactful negative test.
My students and residents know that I want to hear the numbers. Sometimes normal is not normal. Sometimes seemingly normal gives clues.
The problem comes from our laboratory definition of no...

The New FDA Commissioner
By SAURABH JHA, MD
That the appointment of Scott Gottlieb to head the FDA has elicited a decidedly mixed response is a good thing. I fear consensus as much as the late Christopher Hitchens loved dissent which, he believed, was an indicator of a healthy democracy, which means that rather than facing the morgue, the US might be going through her healthiest days in these times.
Gottlieb has served on the boards of industry, and earned a nifty pocket money doing so. Detractors argue that he’s unfit to head the FDA because of his financial conflict of interest (FCOI). I will not revisit the arguments for and against physicia...

Burgers with a side of glomerulonephritis
Kicking off intern year means BBQs, team dinners, and block parties. Every invitation encourages us to bring our significant others, those people who define our existence outside of the hospital. And yet, hot dog and cold drink in hand, it seems we can’t help but alienate our non-medical partners by talking exclusively about the minutiae of our medical lives: our interesting patients, our frustrations, and our philosophies of medicine. They stand there, nodding and looking into the distance, lip curling over as our incomprehensible exchange rambles on.

Red Dust, dingoes, trauma and Sepsis
Guest post by Dr Chris Edwards of EMJourney recounts his time as a remote retrieval registrar based in Alice Springs – @EMtraveller
I’ve had the privilege to work as a Retrieval Registrar for the Alice Springs Hospital Retrieval Service in Central Australia for the last 6 months. How to describe it – words that spring to mind include:
Challenging (unlike many other retrieval jobs, you often are intimately involved in the logistics planning)
Satisfying (providing ICU level care to the most remote parts of Australia)
Scary (providing ICU level care to the most remote parts of Australia!)

Gliadin: The Universal Human Poison
Autoimmunity is the process describing an immune response waged against our own organs. The complex collection of mechanisms consisting of T and B lymphocytes, antibodies, and others, meant to provide protection against viruses, bacteria, and other body invaders, is misdirected against proteins of the body’s organs, such as liver, pancreas, thyroid, or brain. Autoimmune conditions now affect 8% of the American population–it is increasingly looking like diseases of autoimmunity are out of control.

Causative agent of rheumatic fever
:
a) Group A beta hemolytic streptococci
b) Group A alpha hemolytic streptococci
c) Streptococcus viridans
d) None of the above
Correct answer: a) Group A beta hemolytic streptococci
Rheumatic fever is a delayed manifestation occurring weeks after throat infection with Group A beta hemolytic streptococci. It does not occur after streptococcal skin infection, which can cause glomerulonephritis. Rheumatic fever is an immune complex mediated post streptococcal disease.
