Metabolic disease are complex but a few are a slam dunk

29.12.2024 00:31 β π 1 π 0 π¬ 0 π 0No idea.. btw, the original paper (I havenβt it here right now, I will post it) was about osteoporotic fractures in elderly people, so I think itβs not a good idea to apply Genant classification to post-traumatic vertebral fracture in healthy people (like I often read in reports from elsewhere)π€

18.12.2024 19:51 β π 1 π 0 π¬ 0 π 0This has also to do with the prevalence of a disease (another rule of screening, btw), and reminds me what happened several years ago with the fake epidemic of Lyme disease, because of which almost any patient with myalgia was suggested to undergo ELISA test for Lyme diseaseβ¦
18.12.2024 19:49 β π 1 π 0 π¬ 1 π 0Even talking about βsimpleβ brain or spine MRI: my experience is that patients undergoing brain or spine MRI with 0.001% of chances of a significant finding (explaining the symptoms), βjust to be sure and more relaxedβ, are NEVER told that their fear can be even bigger after the MRI π€¦πΌββοΈ.
18.12.2024 19:29 β π 1 π 0 π¬ 2 π 0And, when we inform the patients about WBMRI, how many times do we inform them about the possible scenario of discovering an βunknown thingβ, that will need further exams, maybe invasive/dangerous, provoking anxiety/fears/side effects, maybe for nothing? π€·πΌββοΈ
18.12.2024 19:25 β π 1 π 0 π¬ 1 π 0I then tried to convince you that WBMRI can be even more dangerous than jumping from a skyscraper roof! π Of course, mine was a provocation, to highlight that medical responsibility (in this and other scenarios) canβt be only βto informβ, letting the patients to get the decision by themselves.
18.12.2024 19:21 β π 1 π 0 π¬ 1 π 0Examples showing why βscreening (especially by imaging)β is not always a good thing, even when you find βsomethingβ, are endless.

18.12.2024 19:02 β π 1 π 0 π¬ 1 π 0Even worse with incidental aneurysms: are we sure that it is always π to accidentally discover a cerebral aneurysm? Maybe so small that is not considered treatable.

18.12.2024 18:52 β π 1 π 0 π¬ 1 π 0For several reasons, my friend. 1st: how you get a certain diagnosis of a malignant tumor?

18.12.2024 18:41 β π 1 π 0 π¬ 1 π 0βCan we deny someone the right to jump from a skyscraper roof, if they request it & are willing to cover the cost, once we inform them about pros/cons? Ultimately, the decision should rest in their handsβ. πππΌ
