These data suggest that ICAD causing high-grade stenosis and occlusion are more likely to lead to intracranial obstructions and cerebral or retinal ischemic events. Conversely, ICAD without luminal narrowing cause more local signs and symptoms.

Background and Purpose-Autopsy studies found that lacunar strokes differ in the size of the underlying brain infarct and that small lacunes are usually caused by hypertensive small-artery disease (SAD) and larger ones by atheromatous or embolic perforator occlusion. These findings suggest that larger lacunar infarcts might cause more severe neurological deficits and a higher detection rate on brain imaging compared with lacunar strokes caused by SAD. This prospective observational study was performed to investigate whether (1) neurological outcome, (2) prevalence of stroke risk factors, (3) prevalence of clinically asymptomatic occlusive cerebral artery disease, and (4) detection rate of underlying lacunar infarcts at brain imaging differ in ischemic lacunar strokes with (non-SAD) and without potential etiologies other than SAD. Methods-Consecutive patients with lacunar stroke (nϭ244), defined by both clinical findings and brain imaging, were studied. Neurological deficit was quantified at presentation with the use of the National Institutes of Health Stroke Scale (NIHSS) and after 3 months with the NIHSS and the modified Rankin Scale (mRS). Cerebral arteries were investigated by ultrasound. Results-Compared with patients with SAD lacunar strokes (nϭ155; 64%), patients with non-SAD lacunar strokes (nϭ89; 36%) had (1) higher NIHSS scores at presentation and higher NIHSS and mRS scores after 3 months (PϽ0.05); a higher prevalence of (2)

This study suggests that ICAD has a benign long-term prognosis with low rates of ipsilateral carotid territory and any stroke and that the stroke rate in ICAD is not related to the persistence of severe carotid stenosis or occlusion. These results question the rationale of surgical or catheter-based revascularization in patients with ICAD.

In the past, increases in childhood cancer incidence were reported in Europe and North America. The aim of this study is to show updated patterns of temporal behavior using data of the Childhood Cancer Registry of Piedmont (CCRP), a region with approximately 4.5 million inhabitants in North-West Italy. CCRP has been recording incident cases in children (0–14 years) since 1967 and in adolescents (15–19) since 2000. Time trends were estimated as annual percent change (APC) over the 1976–2011 period for children, and over 2000–2011 for both children and adolescents. CCRP registered 5020 incident cases from 1967 to 2011. Incidence rates were 157 per million person-years for children (1967–2011) and 282 for adolescents (2000–2011). From 1976–2011, increasing trends were observed in children for all neoplasms (APC 1.1, 95%CI: 0.8; 1.5) and for both embryonal and non-embryonal tumors: 1.1%, (0.5; 1.6) and 1.2%, (0.7; 1.6), respectively. Increases were observed in several tumor types, including leukemia, lymphoma, central nervous system tumors and neuroblastoma. In 2000–2011, incidence rates showed mostly non statistically significant variations and large variability. The observation of trends over a long period shows that the incidence of most tumors has increased, and this is only partially explained by diagnostic changes. Large rate variability hampers interpretation of trend patterns in short periods. Given that no satisfying explanation for the increases observed in the past was ever found, efforts must be made to understand and interpret this peculiar and still ununderstood pattern of childhood cancer incidence.

Our study shows a good social adjustment of adult survivors from childhood cancer, with the exception of central nervous system tumors. From the methodologic point of view, the present study shows the feasibility of surveillance surveys on health-related quality of life with the contribution of general practitioners.

Estimates of the economic burden of caregiving on families of children and adolescents with cancer derived from administrative data should be considered a minimum burden. The estimated effect of the covariates is informative for healthcare decision-makers in planning support programmes.

Recurrent TIA or stroke after VAD appears to be extremely rare, independent of recanalization or persistent occlusion of the affected artery. CDUS and TCCDUS provide reliable follow-up of VAD in all patients presenting with stenosis or occlusion, but do not allow for detection of pseudoaneurysms of the VA.
