Results: Whole-brain median ADC was a significant predictor of poor outcome as measured by no eye opening (specificity, 100% [95% confidence interval CI: 86%, 100%]; sensitivity, 30% [ 95% CI: 18%, 45%]) AZD6738 mouse or 6-month modified Rankin scale score greater than 3 ( specificity, 100% [ 95% CI: 73%, 100%];
sensitivity, 41% [95% CI: 29%, 54%]), with patients with poor outcomes having significantly lower ADCs for both outcome measures (P <= .001). Differences in ADC between patients with good and those with poor outcomes varied according to brain region, involving predominantly the occipital and parietal lobes and the putamen, and were dependent on the timing of imaging.
Spatial and temporal differences in ADCs may provide insight into mechanisms of hypoxic-ischemic brain injury and, hence, recovery.”
“In preterm infants, the germinal matrix is a common origin of hemorrhages during the first 7 days of life. Sonographically, germinal matrix hemorrhages present as subventricular echodensities evolving into pseudocysts. Similar lesions have been reported as incidental findings click here also beyond 7 days of life. They may result from vasculitis and ischemic infarction, rather than hemorrhage. To assess the occurrence, time course, and significance for neurodevelopment of such late germinal matrix hemorrhage-like lesions, we reviewed serial cerebral ultrasound examinations obtained in 86 sequentially admitted infants (gestational age <32 weeks or birth weight <1500 g). Neurodevelopment was
assessed at 3 years (Bayley Scales of Infant Development). Nine infants had late isolated germinal matrix hemorrhage-like lesions. Their Psychomotor Development Index scores were significantly lower than that in infants without hemorrhage. Our results suggest that late isolated germinal matrix hemorrhage-like lesions are of clinical significance because of their notable incidence and association with neurodevelopmental Tubastatin A purchase outcome.”
“Background: Lateral mass screw fixation with plates or rods has become the standard method of posterior cervical spine fixation and stabilization for a variety of surgical indications. Despite ubiquitous usage, the safety and efficacy of this technique have not yet been established sufficiently to permit “”on-label”" U.S. Food and Drug Administration approval for lateral mass screw fixation systems. The purpose of this study was to describe the safety profile and effectiveness of such systems when used in stabilizing the posterior cervical spine.
Methods: A systematic search was conducted in MEDLINE and the Cochrane Collaboration Library for articles published from January 1, 1980, to December 1, 2011.
