A rare variant of Wilkie syndrome

PixelFlux is the most sensitive parameter to detect COVID related damage of the microvessels:

Effect of Respiratory Failure on Peripheral and Organ Perfusion Markers in Severe COVID-19: A Prospective Cohort Study

Our results show a significant association between the severity of respiratory failure and the impairment of peripheral and organ perfusion, which seems to be consistent with the pathophysiology of the development of ARDS. The usefulness of DTPM developed by Scholbach was investigated in many clinical applications [39,40,41,43,44]. Lubas et al. proved its usefulness in the assessment of renal perfusion among patients with hypertension and glomerulonephritis. However, DTPM was never investigated in ARDS or septic patients.

“revealed that the RCP [ PixelFlux measurements of renal cortical perfusion (inserted by Th. Scholbach) was the best independent parameter associated with the Oxygenation Ratio (R2 = 0.120; p < 0.001) (Table 7).”

“In the presented study, impaired kidney perfusion (RCP) correlates with the deterioration of gas exchange (Oxygenation Ratio; p < 0.000035 and CT score; p = 0.01).

Moreover, statistically significant associations concerning the relationship between the severity of ARDS and renal cortex perfusion, RCP, (p < 0.0001) were revealed. Nevertheless, according to the stepwise retrograde multivariable regression analysis, RCP was the best independent parameter linked to the Oxygenation Ratio.
Our results also show a correlation between the RCP and urea concentration (p = 0.031), which is consistent with the view of reduced renal flow and impaired renal function in sepsis [41,58]. Existing studies show a decrease in the blood flow through the cortex and medulla of the kidneys in patients with severe COVID-19, visible on magnetic resonance imaging [61].”
“It turns out that the peripheral perfusion parameters FIT (p = 0.038), CRT (p < 0.0006), RCP (p < 0.0002)[the best correlation of all parameters! – inserted by Th.Scholbach], and saturation (p = 0.0021) are better related to the severity of gas exchange than the pressure assessment, MAP, SBP, and DBP (p = 0.683, p = 0.718, and p = 0.474, respectively) (Table 5).”

“only renal cortex perfusion (RCP) was substantially correlated with the CT score (p < 0.010) …(CT score—based on Computer Tomography lung involvement severity score).”

“Dear Professor Scholbach,

…Your brilliant software still works! 😊

Kind regards,

Arkadiusz Lubas”

PixelFlux demonstrates rapid post-dialysis improvement of peripheral nerve perfusion ( BORIRE et al. Prince of Wales Clinical School, University of New South Wales, Sydney, Australia)  :

“… we have shown that peripheral nerve hypervascularity is demonstrable in ESKD patients and rapidly improves following a single session of dialysis. Increased INBF is more likely to be seen in nerves of patients with evidence of axonal loss and moderate to severe neuropathy, suggesting that it may be a potential marker of neuropathy severity.

PixelFlux has significantly higher intra- and interobserver reliability than traditional methods to evaluate intraneural blood flow in carpal tunnel syndrome ( BORIRE et al. Prince of Wales Clinical School, University of New South Wales, Sydney, Australia)
