Michael Jorrin, "Doc Gumshoe"

Author Bio

Michael Jorrin,
I have been a medical writer for about 25 years; before that I was a documentary film maker, and some of my films were about medical subjects. I am not a physician, but I have a pretty good scientific background. I wouldn’t dream of recommending any kind of treatment to anyone, and I cannot give medical advice. However, I understand the medical literature and the data and evidence behind it, and I have an inquiring and skeptical turn of mind. I scrutinize and question and, sometimes, challenge the positions of some of the established health-care organizations as well as the marketers of health information. Eternal vigilance is a small price to pay for health. — Michael Jorrin (aka DocGumshoe) Michael Jorrin is a paid contributor to Stock Gumshoe, he has agreed to our trading restrictions but he chooses his own topics and his words and opinions are his own.

Update on Antibiotic Resistance: December 2019

The headline that snagged my attention was this:  ‘Thirty-five Thousand Americans Die of Antibiotic-Resistant Infections Each Year” This was based on the Centers for Disease Control’s Antibiotic Resistance Threats in the United States, 2019, which led off with the statement that more than 2.8 million antibiotic-resistant infections occur in the US every year, and more […]

Doc Gumshoe – Short & Easy Bits

This particular bit of news leaves your friend Doc Gumshoe shaking his head in puzzlement.  To wit, in the US it is expected that there will be a substantial shortage of physicians in the upcoming years.   The American Association of Medical Colleges predicts that this shortage may reach about 122,000 physicians by the year […]

Cancer: the Changing Landscape in 2019

The publicity material for M. D. Anderson in Houston, Texas, which is perhaps the leading cancer treatment center in the United States, frequently includes a statement to the effect that they are committed to “ending cancer.” That statement puts me in mind of maps dating from the first century AD, in which large unexplored areas […]

Why We Take the Bait

One would think that it would take a person of normal intelligence about half a minute to conclude that lures such as the ones below could not possibly be on the up and up.   Here’s one.  It starts out with a note from Christine O’Brien. “The Sovereign Investor Daily A brand new, ‘Alzheimer’s vaccine’ […]

In Defense of the Egg

Doc Gumshoe is not in the habit of contradicting the conclusions, backed by research, that are stated in papers published by the Journal of the American Medical Association, commonly referred to as JAMA.    JAMA is, after all, one of a handful of the most prestigious medical journals on the planet, along with the New […]

Short Bits for a Short Month

“For such a beastly month as February, 28 days as a rule are plenty,” said the Pirate King.   But you would be surprised at the number of interesting snippets of news in the health-care realm that landed in my inbox during this short month.   I’ll lead off with one that gave me a particular kick. […]

Rapid Response: The Israeli Cure for All Cancers? And a Postscript on Opioids

What set me off on this rant was the very first comment on the piece that posted on January 31st, “Looking Backward – And a Peek in the Other Direction.”   Here’s the comment: “Thanks, Doc. Hope you will comment on the news out of Israel this week: https://www.jpost.com/HEALTH-SCIENCE/A-cure-for-cancer-Israeli-scientists-say-they-think-they-found-one-578939” Naturally, I looked, and what I found […]

Ketamine: Menace or Miracle?

I’ll grant that my headline is meant to be catchy and induce you to read this epistle.   Some of you will ask what is ketamine anyway, and most of you will know from the get-go that ketamine, whatever the heck it is, will turn out to be neither a menace nor a miracle, but something […]

Cancer Treatment 2018: Looking Towards the Future

Most of the attention in the media is now focused on the several forms of cancer treatment grouped under the flattering term “Precision Medicine.”   I find that the term raises my skepticism index just a bit; it’s like eating establishments labeling themselves “Gourmet Restaurants,” the implication being that joints not so identified are just […]

Cancer: The Lay of the Land in 2018

Putting the name of this imperious disease in the title of my homily places a weighty responsibility on me.   Who am I to attempt to put forth relevant information and sensible opinions on this topic, the mere mention of which makes most normal folk distinctly uneasy?   But I probably pay more attention to […]

On Which Is the Real Villain In Heart Disease – Cholesterol or Inflammation?

Pharmaceutical outfits seek FDA approval for new indications for at least a couple of reasons. One, the new indication prompts physicians to prescribe the drug for that indication when they might not have done so otherwise - i.e., it boosts sales. But[...]

Colloidal silver is not in the antibiotic category. It is an anti-infectant, not too disimilar to iodine or alcohol or such. Yes, it can exterminate pathogens, but not without some damage to surrounding tissue.[...]

It would indeed be excellent, but the FDA rule is that once a drug is approved, a physician can prescribe it for anything at all. An antibiotic could be prescribed as a treatment for anything from Addison's disease to Zollinger-Ellison syndrome. Enjoy [...]
