What does the body of evidence have to say about kidney stones (and bladder stones)? You will learn about risk factors for stones; whether or not a low oxalate diet will help; and just exactly what insane stuff our ancestors used to do to help people pass their stones. There’s mention of a “she-ass” and something invasive involving the bum. We’re not even joking.

Obviously, Chris is not your doctor (probably). This podcast is not medical advice for you; it is what we call information.

You thought your toddler was a handful. Have you heard of the She-Hulk toddler? You will learn what GPA means in a patient chart and how menstruation can be used to judge the health of a country, while Chris tries to figure out what is wrong with this tiny but ferocious patient.
Also: an announcement that will change The Body of Evidence forever….
Warning: this episode contains medical discussion of genitals.
A Block: The Case of the She-Hulk Toddler
(0:58) She has the strength of two toddlers! Also, puberty seems to have kicked in. What is going on with her?
B Block: Announcement
(32:29) Chris and Jonathan announce something.

Jonathan and Chris speak to Dr. Andrea Love, a microbiologist, immunologist, science communicator, and the director of the American Lyme Disease Foundation. The tick-borne illness known as Lyme disease is everywhere: on the news, on social media… but is it really near you? Dr. Love separates facts from fiction when it comes to Lyme disease, both the acute infection and the alleged chronic condition.
Correction (2024/07/24): Dr. Love wanted to correct a statement she made. She said that tick-borne relapsing fever does not occur in the U.S., but she meant that it did not occur in the eastern U.S. It does occur in western U.S. states but is caused by a different Borrelia species and spread by different ticks, so there is no overlap with Lyme disease.

What does the body of evidence say on malaria? Your favourite travel destination may be a malaria hot zone: we discuss how to prepare. Plus: a strange FDA application to use MDMA to treat PTSD, and have statins been overprescribed?

What does the body of evidence say on LASIK, the use of lasers to correct vision? Plus: many men on PreP are abandoning condoms as STIs are becoming more common, and Chris tells us if krill oil can cure arthritis of the knee. Also, Jonathan briefly imitates Alex Jones.

(0:59) How lasers are used in medicine; LASIK and its cousins; how to choose; effectiveness, satisfaction, and side effects.
B Block: HIV PrEP and STIs
(28:18) How does pre-exposure prophylaxis against HIV works, and what is simultaneously happening with condom use (going down) and rates of STIs (going up). Also, what is Doxy-PEP?
C Block: Krill Oil for Knee Osteoarthritis
(44:45) An Australian trial of krill oil for arthritis of the knee came to the conclusion that… well, what do you think?

Jonathan and Chris speak to Dr. Matthew Cameron, a local anesthesiologist who does a lot more than local anesthesias! They discuss the ins and outs of putting people to sleep; how safe epidurals really are; and whether or not you need to worry about waking up paralyzed in the middle of an operation (spoiler alert: no). Also, Jonathan is told about “blood patches” for the first time and can’t believe this is a real thing.

It’s the case of the woman who was too tired to “par-tay!” What is afflicting her? It’s something that we don’t about enough. Plus: what is happening with avian flu and should you keep using Q-tips in your ears to remove earwax?
