Exciting to see the growing list of doctors. I won't be able to attend and take notes this time, due to work conflicts. It will so interesting to see the abstracts and information that has been gleened since September 2009 in Bologna. I'll try to make them available as soon as possible.
I'm thrilled to note that Dr. Gabbiani will be speaking again. He is a vascular professor at the University of Geneva, and has published hundreds of papers-- he studied jugular vein tissue in pwCCSVI and found a collagen shift in the entire vein, not just the area of stenosis. A morphological change which has been connected to artheriosclerosis in arteries, not seen in veins before. Also a repeat visit from Dr. Franceschi, the pre-eminent vascular specialist of France. Dr. Ferlini is the Italian DNA specialist, and she has been looking at the connection in copy number variations in vascular malformations and MS.
And many new doctors, with representation from the UK, and more new names from the US and Italy. These are not Zamboni cronies. These are highly respected researchers. And they are all gathering to make sense out of venous abnomalities found in pwMS.
Very exciting times,
cheer

I used to know what optical coherence tomography was!drsclafani wrote:optical coherence tomography
here we go:
Optical coherence tomography (OCT) is a new, noninvasive, noncontact, transpupillary imaging technology which can image retinal structures in vivo with a resolution of 10 to 17 microns. Cross-sectional images of the retina are produced using the optical backscattering of light in a fashion analogous to B- scan ultrasonography. The anatomic layers within the retina can be differentiated and retinal thickness can be measured.

Do you know if that's a collagen shift that is permanent or is it reversible, either in CCSVI or in artheriosclerosis?I'm thrilled to note that Dr. Gabbiani will be speaking again.

OCT is a technique that can image live tissue similar to what ultrasound does but with much higher resolution.Cece wrote:I used to know what optical coherence tomography was!drsclafani wrote:optical coherence tomography

Cross-sectional images of the retina are produced using the optical backscattering of light in a fashion analogous to B- scan ultrasonography. The anatomic layers within the retina can be differentiated and retinal thickness can be measured.
It is like looking at a pathology slide under the microscope but with live tissue.
The resolution is so great that in patient with MS we can often quantify a thinning of the nerve fiber layer near the optic nerve specially if the patient had optic neuritis in the past and that tissue is only few microns thick.
Here of course they are referring to intravascular OCT and the bottom line is: if you like IVUS you will love Intravascular OCT.
To be applied to the vascular tissue they use infrared wavelength to overcome the opacity of the medium.
Optical Coherence Tomography (OCT) is the Extreme Resolution™ imaging technology for cardiovascular disease diagnosis. LightLab OCT utilizes near-infrared light to create images with 10 times the resolution of Intravascular ultrasound (IVUS). The proprietary LightLab OCT interferometer analyzes reflected light waves to create our extreme resolution Golden Image™ for enhanced diagnosis and treatment decisions.
The bandwidths of infrared light utilized for OCT are far higher than ultrasound, resulting in greatly increased image resolution. In fact, LightLab OCT provides intravascular images with 15 micrometer axial resolution, about twice the size of a red blood cell. Despite providing this extreme resolution LightLab OCT is a radiation-free* imaging medium.

is this the ideal screening tool? - P. Zamboni Italy
Plethysmography is the recording of changes of body volume.
It is used to check your lung function or, more interesting for us, the blood flow.
Cervical means neck so they are talking about an instrument that check blood flow in the neck.Unless you were talking about this other test::oops:Plethysmography is a test used to measure changes in blood flow or air volume in different parts of the body. It may be done to check for blood clots in the arms and legs, or to measure how much air you can hold in your lungs.
Plethysmography is a non-invasive technique for measuring the amount of blood flow present or passing through, an organ or other part of the body. Plethysmography is used to diagnose deep vein thrombosis and arterial occlusive disease.
Plethysmography is used as the sole diagnostic modality for these conditions, or as an initial evaluation to determine the need for venography or arteriography. A variety of plethysmographic techniques are available.Penile plethysmography (PPG), or "phallometry", is a controversial type of plethysmograph that measures changes in blood flow in the penis.[

The collagen shift in artheriosclerosis can be reversable--if it is due to inflammation (from environmental issues like diet) and disturbed blood flow that can be corrected. If it is due to a genetic condition, like Ehler Danlos disease, it is permanent. The doctors continue to study this. The truth may be that some is congenital, some is situational.Cece wrote:

It's quite a line up of speakers...hope someone is able to go and report back to us all.
And as far as your return of vivid color perception, Cece....we need only look to the reduction of diffuse cerebral hypoxia in your brain thanks to Dr. Sclafani's skills....
http://www.springerlink.com/content/u44986g78877w715/This study reports the effect of a moderate level of hypoxia on human color discimination. We found a generalized loss of color vision affecting both red-green and blue-yellow discrimination at an altitude of 12,000 feet. Although the residual color discrimination at this altitude was within age-matched, sea-level norms, a statistically significant increase over sea level error scores was measured on the Farnsworth-Munsell 100-Hue test and the Pickford-Nicolson anomaloscope. An analysis of psychophysical and electrophysiological studies indicates that hypoxia acts by depressing retinal ganglion cell activity and that it can affect photopic visual processes as well as scotopic vision. We conclude that studies evaluating man's visual performance at altitude must consider post-receptoral processes.
Your brain has been living at high altitude....welcome to sea level!
keep healing, we're going to need your energy to help others,

yes - a neck collar contraption that measures blood flow - sorry, I wasn't very clear last night! There are pictures of it in the article CuriousRobot linked, if it's the same as the article we had before, and it is a bizarre looking thing but exciting if it delivers more accurate or reproducible results than the other imaging methods thus farCuriousRobot wrote:Noninvasive measurement of central venous pressure by neck inductive plethysmography.Nunzio wrote: I do not know how you came up with this one.

I wish I'd have done a before-and-after Hue test or Pickford-Nicolson anomaloscope! How validating it would've been to have this measured.
Hypoxia depresses the retinal ganglion cell activity, which affects photopic visual processes and scotopic vision...I am going to have to look some of this up.
