The role of Alberta Stroke Program Early CT score (ASPECTS) in predicting which patients are likely to benefit from endovascular therapy (EVT) is not well defined. An automated software (e-ASPECTS) has been created to solve its poor interrater reliability. We aim to evaluate correlation between radiologist (Rx) and e-ASPECTS scoring with cerebral blood volume (CBV) infarct core and with final infarct volume; as well as with long-term functional outcome. ⋯ ASPECTS and e-ASPECTS showed a mild correlation with CBV. Rx-ASPECTS, e-ASPECTS, and CBV predicted a low infarct volume after thrombectomy in recanalized patients but only Rx-ASPECTS and e-ASPECTS predicted functional independence at 3 months.

Bowel incontinence in multiple sclerosis might be associated with specific lesion sites. This study intended to determine associations between bowel incontinence and cerebral multiple sclerosis lesions using a voxel-wise lesion symptom mapping analysis. ⋯ Our analysis indicates associations between bowel incontinence and lesions in the left supramarginal gyral area contributing to integrating anorectal-visceral sensation and in the right parahippocampal gyrus and amygdala contributing to generating visceral autonomic arousal states. Moreover, our results suggest left hemispheric dominance of sensory visceral integration, while limbic areas of the right hemisphere seem to contribute to the autonomic component of the defecation process. A limitation of our study is the retrospective evaluation of the bowel incontinence status based on medical records. Further research should evaluate the bowel incontinence status in multiple sclerosis patients prospectively to overcome the limitations of the current study.

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.

Several studies have aimed to find potential biomarkers to simplify the diagnosis of chronic inflammatory demyelinating polyneuropathy (CIDP) and to monitor and predict the disease course. However, reliable markers are still lacking. We aimed to investigate whether high-resolution nerve ultrasound (HRUS) is suitable for monitoring the long-term clinical course of CIDP. ⋯ Nerve ultrasound can be used as a method to objectify the long-term disease course in CIDP patients. The intranerve CSA variability is suitable for monitoring the clinical course of patients with CIDP.

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.
