    Cancer: extracorporeal treatment

    In oncology, the 15 years of research carried out by surgeons Aris Zonta and physicist TazioPinelli have revolutionized the treatment of this pathology because it can be treated extracorporeally. The technique involves removing the organ from the body, administering radiotherapy treatment and relocating it. This extracorporeal operation allowed the doctors to administer high doses of radiation to the various tumors disseminated on the organ, without affecting the surrounding organs. But concretely, the surgeons proceed to an injection of a compound with boron atoms absorbed by the cancer cells. A reactor can project neutrons onto the organ and once irradiated by neutrons, the boron atoms disintegrate and destroy the cancer cells. This method of cancer treatment could very well extend to other transplantable organs, such as the kidneys, lungs, pancreas, etc.

    Mini-electrodes technique

    As for neurosurgery, which has had a bad reputation in recent years, new technologies recently discovered will greatly improve the reputation of this discipline. The new technique is virtually devoid of complications and does not result in permanent brain damage. It involves the introduction of mini-electrodes delivering high frequency pulses within a deep brain zone the size of a pea. High frequency stimulations inhibit neurons and interrupt the transmission of the nerve message. Targeted neuron clustering is involved in a particular control that one wants to modify. Electrical stimulation of these brain structures changes their function and improves symptoms. Thanks to the development of brain imaging, some areas have been identified with precision. Once in place, the stimulations are done without the patient being aware and the electrodes are not visible from the outside. This process works on the same model as the pacemaker for the heart, the two electrodes are connected to the stimulator placed under the skin.

    Multi-track system

    In cardiovascular surgery, tremendous progress has also been made and developed, especially by surgeon Philipp Bonhoeffer. We can mention the case of the multi-track system, which is today used very frequently, and whose intervention is commonly called angioplasty or arterial dilatation. This procedure can restore normal blood flow in the arteries narrowed by plaque atherosclerosis (accumulation of cholesterol). Philippe Bonhoeffer, based on his experience in Africa, has developed a technique that consists of inserting into the clogged artery a thin balloon-terminated catheter which, once inflated, dilates the artery and allows a restoration of blood flow. . But within six months of this procedure, three complications can occur: an elastic retraction of the arterial wall decreasing its diameter, a proliferation of cells due to tissue healing and chronic vasoconstriction of the vessel. This is called post-angioplasty restenosis. It is then possible to deposit a small wire mesh inside, the stent, which, like a spring, keeps the artery open when the balloon is removed. It reduces the rate of restenosis by 30% by limiting elastic recoil and vasoconstriction, but it does not prevent cell proliferation. But in this case, the use of ionizing radiation could provide an effective solution.
