Statistical analyses were performed by using Student t and Pearson chi(2) tests.

Results: Multidetector CT venography depicted thrombosis of 98 dural sinuses or jugular bulbs in 57 (40.7%) of the 140 patients with skull fractures extending to a dural sinus or jugular bulb. Fifty-four (55%) of the 98 sinuses or bulbs had occlusive thrombosis. DVST was seen in only those patients with skull fractures extending to a dural sinus or jugular bulb. Among the skull fractures extending to the transverse sinus, sigmoid sinus, or jugular bulb, those of the petrous temporal bone had a higher risk (50%, 36 of 72 fractures) of traumatic DVST than did those of the occipital Selleck GW-572016 bone (34% risk [ 32 of 93 fractures]) (P

= .044). However, among the skull fractures extending to the superior sagittal sinus, those of the occipital bone had a higher risk (67% [ eight of 12 fractures]) of traumatic DVST than did those of the parietal (39% risk [ 11 of 28 fractures]) and frontal (24% risk [ four of 17 fractures]) bones (P = .065). Four (7%) patients with traumatic DVST had associated hemorrhagic venous infarctions, all secondary to occlusive DVST.

Conclusion: In patients with blunt head trauma, multidetector CT venographic evaluation

should be performed only if there is a fracture extending to a dural venous sinus or jugular bulb. (C) RSNA, 2010″
“A micromagnetic numerical study of the precessional motion of the vortex and antivortex states in soft ferromagnetic circular nanodots is presented using Landau-Lifshitz-Gilbert dynamics. For sufficiently Selleckchem KPT-8602 small dot thickness and diameter, the vortex state is metastable and spirals

toward the center of the dot when its initial displacement is smaller than a critical value. Otherwise, the vortex spirals away from the center and eventually exits the dot which remains in a state of in-plane magnetization (ground state). In contrast, the antivortex is always unstable and performs damped precession resulting in annihilation at the dot circumference. The vortex and antivortex frequencies of precession are compared with the response expected on the basis of Thiele’s theory of collective coordinates. LBH589 mouse We also calculate the vortex restoring force with an explicit account of the magnetostatic and exchange interaction on the basis of the “”rigid”" vortex and “”two-vortices side charges free”" models and show that neither model explains the vortex translation mode eigenfrequency for nanodots of sufficiently small size.

“Aim:

With cancer cases expected to rise in the coming decades, increased demands will be placed on our health system to address the psychosocial care of patients affected by cancer. The objective of this study was to review the evidence on the cost effectiveness of psychological interventions for individuals with cancer.
