Meet the Interstitium, the Largest Organ We Never Knew We Had (thedailybeast.com) 208

An anonymous reader quotes a report from The Daily Beast: A study published in Scientific Reports on Tuesday suggests that a previously unknown organ has been found in the human body. More astonishingly, the paper puts forth the idea that this new organ is the largest by volume among all 80 organs -- if what the researchers found is, in fact, an organ. The new organ, [pathologist Neil Theise] explained, was a thin layer of dense connective tissue throughout the body, sandwiched just under our skin and within the middle layer of every visceral organ. The organ also made up all the fascia, or the thin mesh of tissue separating every muscle and all the tissue around every vein and artery, from largest to smallest. What initially seemed to be a solid, dense, connective tissue layer was actually a complex network of fluid-filled cavities that are strong and flexible, yet so tiny and undiscerning that they escaped the attention of the brightest scientific minds for generations. In fact, Theise expanded, this "interstitium" could explain many of modern medicine's mysteries, often dismissed by the establishment as either silly or explainable by other phenomena. Take acupuncture, Theise said -- that energetic healing jolt may be traced to the interstitium. Or perhaps the interstitium acted as a "shock absorber," something that protected other organs and muscles in daily function. Also, the space is in direct communication with the lymphatic system as the origin of lymph fluid -- which means the interstitium's system of fluid-filled backroads could explain the metastasis of cancer cells and their quick spread beyond the limits of the organ in which the cancer started.

    I propose:

    The interstitium is the body's internet.

    After all, it's a very small layer of tubes that transmits through the entire body...

        When you are sick, it's like your interstitialian is a highway that's jammed with traffic.

        Alternately, you could say if the human being were a car, the interstiliarium is roughly equivalent to the rich Corinthian leather covering the seats and dash.

        • Since the bloodstream and lymphatic system also connect different tissues together in an already well demonstrated fluid transfer network of blood vessels, the transfer of cancerous cells from one organ to another would not seem to require explanation. And since acupuncture consistently fails double blind experiments, that would seem to be another "mystery of modern medicine" that would seem to be already explained, as a placebo effect.

              The problem is that acupuncture rarely has effects either. In every test it has shown to only be as effective as a placebo. Even in China it was recognized as quackery and outlawed.

              It's testable by "poking" somewhere else than where the practitioner would plan. As I understand it, Different practitioners have different patterns for what disorders or issues are treated by different acupuncture points. If there is no verifiable association between the acupuncture points and the disorders, if it doesn't matter which acupuncture points are used, then that indicates it's a placebo effect.

              • Double-blind means that the person administering the treatment or placebo does not know the difference (in addition to the patient). So if you are being poked in a place other than where the practitioner would plan, then you might have a problem being able to do a double-blind study. In general, if a procedure or theory is not falsifiable (testable) then its probably a sham.

                  Double-blind study means that neither patient or person _compiling the results_ knows if this was placebo or real treatment. In many cases outside of simple medicine switch, person executing the experiment (as it goes outside of just medical subjects) is very well aware if it is real or not, he just labels it in secret which will get revealed after all the single measurements and compilations on A/B (rather than placebo/real) are finished.

                  There is, as best I can tell, no master map used by all or even most practitioners.

              Leave the poking to the assistant who doesn't know jack shit about where he/she SHOULD poke - just how to stick the needle into a predesignated spot marked on a drawing.

                That is interesting ... but I guess it only would work if the subject does not notice the poke.

    Now that this structure of what appears to be the container for the extracellular fluid and a major shock absorber for tissues has been identified, it will be interesting to see what disease processes might be the result of degradation of its function.

    I'd expect examination of breakdowns in this system to result in the causes of several diseases, currently dismissed as psychosomatic or as real but mysteries, to be identified.

    I'd also expect that the structure might degrade in old age, and that this might be another source of age-related problems.
