Patient had unknown liver failure and drank a ton of green tea. Liver failure went away while still drinking tons of lower quality stuff. He proceeded to limit high quality green tea without it coming back, but if it was unrelated it wouldn't have come back regardless if he limited green tea or not.
We were all burningly curious whether the liver failure would come back if he resumed his normal green tea consumption, especially him (very "try everything, you only live once" type of personality; see also, consumption of mysterious Peruvian rain forest drugs), thus proving whether the tea was the culprit or not, but for ethical reasons I had to caution him against experimenting on the only liver he had, and he reluctantly agreed he wasn't THAT curious. Therefore, the cause of his liver failure will never be fully and conclusively proven to be green tea.

It's been a bit since my dad was in a hospital, but they wanted to know about literally everything that entered his mouth.
A young man presented in our hospital with acute liver failure. He'd just spent a month traveling through the rain forests of Brazil, Colombia and Peru. During his trip, he'd consumed unknown drugs in a Peruvian shaman ceremony and had unprotected sex with a Peruvian sex worker.
We tested him for everything obvious. He didn't test positive for any known drugs or any obvious drug-related toxins. He didn't have HIV. He didn't have hepatitis A, B, or C. He didn't have EBV, he didn't have CMV, he didn't have Dengue Fever, he didn't have Yellow Fever, he didn't have Malaria. He didn't have any sign of autoimmune conditions.
We called the institute for tropical diseases. We tested him for tropical diseases we'd never even heard of. He didn't have those. He didn't have Syphilis. He didn't have Gonorrhea. He didn't have liver cancer, or any other discernible cancers.
We called the institute for tropical diseases again. They started researching. We tested him for diseases the experts for tropical diseases hadn't even heard of. He had none of those, either.
His liver, which had started failing for no discernible reason, now stopped failing, for equally indiscernible reason. We started planning his discharge.
We had a nice final discussion. He really appreciated how hard we'd tried, he said, and he really appreciated how kind everyone had been, and sorry again about the unprotected sex with sex workers thing, that was effing stupid in retrospect. He said he was looking forward to getting home and detoxing from all this. He said he didn't think the green tea we had on the ward (cheap, shit, comes in bags, unlikely to have ever encountered a tea plant in real life) did anything much, detox-wise, and anyway he'd feel bad emptying our hot water carafe all the time.
Um. How much green tea do you drink, I asked him.
4 to 5 liters per day, he said.
I googled "green tea liver failure," with some vague memory that sometimes tea gets contaminated during the drying process and maybe he'd caught a bad batch? Turns out, green tea just... causes liver failures, occasionally, in higher doses. Probably due to the anti-oxidants.
You live and you learn.
The patient went home and limited his green tea consumption to no more than a cup per day. He checked in with me a year later, because I'd asked him for an update, and his liver was doing perfectly fine and had never failed him again.
Going by that logic, the president's bunker under the pentagon would've been built without a lock. After all, people don't usually have to physically drag a country's leader out of their locked bunker, right? By the time anyone's knocking on that door, usually the war is lost and the country has surrendered.
And yet, if you're designing for defense, why NOT take such a cheap and easy countermeasure as putting a lock on the door or choosing the more defensible way to spiral your staircase? You might want to buy a few more minutes to negotiate in a desperate situation; you might want at least the option of taking that futile last stand; you might be facing not an invading army but a single lunatic with a sword who snuck past the outer guards.
We know vaccines aren't the cause, because large-scale studies have been done that show that autism rates aren't higher in vaccinated children. This leaves us with basically every other possible cause, including not just better diagnostics (I personally find that explanation highly plausible), but also changes in nutrition, effects of some sort of virus, pollution, microplastics and everything else under the sun that's changed in the last decades.
The classic "strong above the waist, paralyzed from the waist down" image of a wheelchair user that people might have from eg the paralympics is the minority.
Stem cell transplantation is a standard treatment for several blood cancers, but will almost certainly never be a standard HIV treatment for anyone except patients who need a transplantation anyway, for one single reason: with modern medicine, living with transplanted stem cells is significantly worse than living with HIV.
With modern meds, HIV patients can have a normal life expectancy and live basically normal lives.
You know how in traditional organ transplantation, your own immune cells will attack and often destroy the transplanted organ? In stem cell transplantation, your transplanted immune cells will attack every single organ in your body. Look up "graft versus host disease."
After stem cell donation, most patients will have to take immuno-suppressants that a have significantly worse side effects than modern HIV meds do, often for the rest of their lives - and that's the lucky ones, where the meds will successfully treat the graft versus host disease. One of the more gruesome sights I've seen in my medical career was a lady with a severe graft versus host skin reaction that her doctors couldn't get under control despite massive doses of immuno-suppressants. Eventually large parts of her skin peeled off in strips, like something out of a horror movie. Then she died of pneumonia from the immuno-suppressants.
This is an extreme example, of course, and many people live perfectly ordinary lives after stem cell transplantation, but the failure more is both more likely and more gruesome than the one for antiviral HIV treatment.
