EEG-fMRI study of the ictal and interictal epileptic activity in patients with eyelid myoclonia with absences 总被引:1,自引:0,他引:1
Liu Y Yang T Liao W Yang X Liu I Yan B Chen H Gong Q Stefan H Zhou D 《Epilepsia》2008,49(12):2078-2086
Purpose: To investigate the blood oxygenation level‐dependent (BOLD) signal changes correlated with ictal and interictal epileptic discharges using electroencephalography‐correlated functional magnetic resonance imaging (EEG‐fMRI) in patients with eyelid myoclonia with absences (EMA) and then to explore the pathophysiological mechanisms of epileptic discharges and their effect on brain function. Methods: Four patients with EMA were investigated through the method of EEG‐fMRI. The characteristics of BOLD signal changes linked to ictal and interictal epileptic discharges under different states of consciousness were explored. Results: Seven sessions of EEG‐fMRI scanning in the four patients were obtained. The main regions of activation included thalamus, mesial frontal cortex, middle parietal lobe, temporal lobe, insula, midline structures, and cerebellum. Deactivations were mainly in the anterior frontal lobe, posterior parietal lobe, and posterior cingulate gyrus. Thalamic BOLD change was predominantly activation in most of our cases. The distribution of activation associated with ictal epileptic discharges was wider, and the distribution of deactivation was closer to pericortex compared with the BOLD change linked with interictal epileptic discharges. Conclusions: The activation in the thalamus may be associated with generalized spike wave in EMA; the combination of different patterns of activation with consistent pattern of deactivations (“default” pattern) in patients with EMA may prognosticate different states of consciousness in response to ictal and interictal epileptic discharges. 相似文献

Background. Improved postoperative outcome has been demonstratedby perioperative maximization of cardiac stroke volume (SV)with fluid challenges, so-called goal-directed therapy. OesophagealDoppler (OD) has been the most common technique for goal-directedtherapy, but other flow-related techniques and parameters areavailable and they are potentially easier to apply in clinicalpractice. The objective of this investigation was thereforeto use OD for preoperative SV maximization and compare the findingswith a Modelflow determined SV, with an OD estimated correctedflow time (FTc), with central venous oxygenation () and with muscle and brain oxygenation assessedwith near infrared spectroscopy (NIRS). Methods. Twelve patients scheduled for radical prostatectomywere anaesthetized before optimization of SV estimated by OD.A fluid challenge of 200 ml colloid was provided and repeatedif at least a 10% increment in OD SV was obtained. Values werecompared with simultaneously measured values of Modelflow SV,FTc, and muscle and cerebral oxygenation estimated by NIRS. Results. Based upon OD assessment, optimization of SV was achievedafter the administration of 400800 ml (mean 483 ml) ofcolloid. The hypothetical volumes administered for optimizationbased upon Modelflow and differed from OD in 10 and 11 patients, respectively. Changes in FTcand NIRS were inconsistent with OD guided optimization. Conclusion. Preoperative SV optimization guided by OD for goal-directedtherapy is preferable compared with Modelflow SV, FTc, NIRSand until outcome studies for the latter are available. 相似文献

Transatlantic cancer survival comparisons are scarce and involve mostly aggregate European data from the late 1980s. We compare the levels of cancer patient survival achieved in Germany and the United States (US) by the beginning of the 21st century, using data from the Cancer Registry of Saarland/Germany and the SEER Program of the US. Age-adjusted 5- and 10-year relative survival for 23 common forms of cancer derived by period analysis for the 2000-2002 period were calculated, with additional detailed age- and stage-specific analyses for cancers with the highest incidence. Among the 23 cancer sites, 5 (10) year relative survival was significantly higher for 1 (2) and 8 (5) cancers in Germany and the US, respectively. In Germany, survival was significantly higher for patients with stomach cancer, whereas survival was higher in the US for patients with breast, cervical, prostate, colorectal and oral cavity cancer. Among the most common cancers, age-specific survival differences were particularly pronounced for older patients with breast, colorectal and prostate cancer. Survival advantages of breast cancer patients in the US were mainly due to more favorable stage distributions. This comprehensive survival comparison between Germany and the US suggests that although survival was similar for the majority of the compared cancer sites, long-term prognosis of patients continues to be better in the US for many of the most common forms of cancer. Among these, differences between patients with breast and prostate cancer are probably due to more intensive screening activities. 相似文献
