RESUMEN
Subjects with migraine are at increased risk of subcortical white matter lesions (WML). Reports of cognitive testing in adults with migraine have yielded inconsistent results. We performed a cross-sectional study to assess whether migraine without aura (MwA) is associated with impairment in executive functioning, a typical cognitive correlate of subcortical WML. Forty-five subjects with MwA and 90 controls, matched for age and education, underwent a cognitive battery of tests evaluating executive functions. The following migraine characteristics were collected: age at onset and length of migraine history, and frequency, duration and intensity of attacks. Subjects with MwA performed significantly lower than controls in tests evaluating complex, multifactorial executive functions. After multiple adjustments, the duration and intensity of migraine attacks significantly predicted cognitive disturbances. In the interictal phase of MwA there is evidence of mild executive dysfunction. The cumulative effects of repeated migraine attacks on prefronto-cerebellar loop probably account for our results.

Experimental and clinical observation suggest that patients with primary biliary cirrhosis (PBC) have endothelial dysfunction. Postischemic digital blood flow, nailfold capillaroscopy, von Willebrand factor (vWf) and tissue-type plasminogen activator (t-PA) plasma levels were examined in 59 PBC patients. Forty-six subjects (15 with liver diseases other than PBC, 11 hypercholesterolemics, 20 healthy subjects) served as controls. PBC versus healthy controls (209.8 +/- 1.4% and 16.54 +/- 1.44 ng/ml vs. 120.2 +/- 1.4% and 9.91 +/- 1.49 ng/ml; p<0.001) and related to bilirubin (r = 0.38, p<0.02; r = 0.47, p<0.0005, respectively). vWf was also increased in other liver diseases (249.9 +/- 1.7%; p<0.001) and related to bilirubin (r = 0.59, p<0.05). Postischemic finger blood flow negatively correlated with vWf(p<0.05 or less). Our data indicate that PBC patients have microvascular disease. Whether vessels other than those of the fingers were involved remained unclear. vWf and t-PA might reflect a dysfunction of teh hepatic vascular endothelium.
