We present the clinical, electrophysiological, and nerve ultrasound findings in cases of persistent carpal tunnel syndrome (PCTS). ⋯ Our data show significant functional disability, axonal nerve damage, and scar tissue formation as common PCTS causes.

Early ischemic changes on noncontrast computed tomography (NCCT) are often subtle. We developed a novel postprocessing technique that aids in detecting such changes. ⋯ In this proof-of-concept study, the rNCCT appears promising for detecting and quantifying early ischemic changes. These findings should be confirmed in a larger cohort.

Impaired distal perfusion predicts neurological deterioration in large artery atherosclerosis. We aim to determine the optimal threshold of Tmax delay on perfusion imaging that is associated with neurological deterioration in patients with symptomatic proximal anterior circulation large artery stenosis. ⋯ A target mismatch profile using Tmax > 6 seconds may define tissue at risk in patients with acute symptomatic proximal anterior circulation intracranial stenosis. More studies are needed to confirm our findings.

The complex function of memory has been linked to both brain gray and white matter (WM). WM abnormalities are associated with memory impairment in pathological conditions. We investigated whether variation in WM microstructure in healthy children also correlates with memory performance. ⋯ Significant correlations between DTI parameter values and CMS indices in multiple WM tracts in healthy children indicate that neuroimaging can sensitively detect brain WM changes associated with variations of memory function, even for that in the normal range.

Although femoral neuropathy is recognized as an adverse consequence following transfemoral neuroendovascular procedures, no reliable estimates are available. We analyzed data from a prospective registry to ascertain the frequency and characteristics of femoral neuropathy following transfemoral neuroendovascular procedures. ⋯ Femoral neuropathy is a rare occurrence following transfemoral neuroendovascular procedures and it usually occurs with pure sensory manifestations with complete resolution.
