Does neuropsychological and positron emission tomography correlate in idiopathic environmental intolerances?
No consistent pathological cognitive performance and functional imaging pattern was found. It appears premature to claim specific neuropsychological or neuroimaging findings characteristic of idiopathic environmental intolerance. Therefore cerebral F-18 FDG PET should not be used to corroborate or rule out suspected idiopathic environmental intolerance, a syndrome whose potential biological underpinnings still need to be clarified.
The poorer recurrence-free outcome for black patients even after multivariate adjustment suggests a potentially more aggressive variant of prostate cancer in this population, the etiology of which is unknown. Race should be a stratification factor in clinical trials, especially those including radical prostatectomy and using recurrence-free outcome as an end point.
