“Menkes disease (MD) is an infantile—onset X-linked recessive neurodegenerative disorder caused by deficiency or dysfunction of a copper-transporting ATPase, ATP7A. The effect of altered transportation of copper may affect various

enzymatic functions differently. Among all enzymatic functions, lysyl-oxidase enzymatic activity, which is crucial in the formation of the lysine-derived cross-links in collagen and elastin, is the most sensitive to the copper transport alterations. PR 171 Pili torti, tortuous intracranial vessels and bladder diverticula are clinical aspects strictly related to the connective tissue alterations dependent on the lysyl-oxidase deficiency. Despite a pleiotropic clinical appearance of MD patients, we observed tortuous intracranial vessels and bladder diverticula in 4 consecutive Menkes patients at different stages of the disease. We speculate that these findings are present at early stages and could be considered suggestive findings in MD. “
“We retrospectively reviewed neuroradiology database

at our tertiary-care hospital to search for patients with metaphoric or descriptive signs on brain computed tomography or Wnt inhibitor magnetic resonance imaging. Only patients who had clinical or pathological definitive diagnosis were included in this review. “
“This study aimed to identify clinical and ultrasound imaging predictors of progression of carotid luminal narrowing in subjects with asymptomatic moderate internal carotid artery (ICA) stenosis.

A total of 571 subjects with asymptomatic moderate (50-69%) ICA stenoses were enrolled. They underwent ultrasound examination at baseline and after 12 months. Demographics, vascular Thiamet G risk factors, medications, plaque characteristics (surface and echogenicity) and common carotid intima-media thickness (IMT) were collected. At the follow-up examination, any change of ICA stenosis was graded in three categories (i) ≥70% to near occlusion, (ii) near occlusion, and (iii) occlusion. Progression of stenosis was defined as an increase in the stenosis degree by at least one category from baseline to follow-up. At 12 months, progression occurred in 142 subjects (prevalence rate 25%). At the multivariable logistic model, pathological IMT values (considered as binary variable: normal: ≤1 mm vs. pathologic: >1 mm) significantly predicted the risk for plaque progression after adjusting the model for possible confounders (OR 2.28, 95% CI 1.18-4.43, P = .014, multivariable logistic model). Our results confirm the role of carotid wall thickening as a marker of atherosclerosis. Carotid IMT measurement should be considered to implement risk stratification in patients with asymptomatic carotid disease. “
