OBJECTIVES: Cure from seizures due to cavernomas might be surgically achieved dependent on both, the complete removal of the cavernoma as well as its surrounding hemosiderin rim. High field intraoperative MRI imaging (iopMRI) and neuronavigation might play a crucial role to achieve both goals. We retrospectively investigated the long-term results and impact of intraoperative 1.5T MRI (iopMRI) and neuronavigation on the completeness of surgical removal of a cavernous malformation (CM) and its perilesional hemosiderin rim as well as reduction of surgical morbidity.  相似文献

The field of women's health developed based on the recognition that there are important sex‐based differences regarding several aspects of medical illnesses. We performed a literature review to obtain information about differences between women and men for neurological movement disorders. We identified important differences in prevalence, genetics, clinical expression, course, and treatment responses. In addition, we found that female life events, including menstruation, pregnancy, breast feeding, menopause, and medications prescribed to women (such as oral contraceptives and hormone‐replacement therapy), have significant implications for women with movement disorders. Understanding this biological sex‐specific information can help improve the quality and individualization of care for women with movement disorders and may provide insights into neurobiological mechanisms. © 2013 International Parkinson and Movement Disorder Society  相似文献

Introduction: The purpose of this study was to evaluate the relationship among sensory function, disease severity, and upper extremity force production in adults with type II diabetes (T2D) as compared with healthy age‐ and gender‐matched controls. Methods: Ten adults with T2D and 10 healthy age‐ and gender‐matched control subjects underwent a battery of sensory and motor function evaluations. Data on disease severity and duration were also collected. Results: The T2D group exhibited sensory deficits and altered force production as compared with healthy controls. Sensory function correlated with disease severity, as did signal predictability of kinetic output during submaximal force production tasks. Maximal force production tasks were associated with altered output in T2D, but these data did not correlate with disease severity or sensory dysfunction. Conclusions: Some, not all, motor performance deficits in T2D are associated with sensory dysfunction. Mechanisms responsible for these changes in adult‐onset T2D are described.

Our goal in this report was to determine whether symptom progression in primary lateral sclerosis (PLS) was consistent with disease spread through axonal pathways or contiguous cortical regions. The date of symptom onset in each limb and cranial region was obtained from 45 PLS patient charts. Each appearance of symptoms in a new body region was classified as axonal, contiguous, possibly contiguous, or unrelated, according to whether the somatotopic representations were adjacent in the cortex. Of 152 spread events, the first spread event was equally divided between axonal (22) and contiguous (23), but the majority of subsequent spread events were classified as contiguous. Symptom progression in PLS patients is consistent with disease spread along axonal tracts and by local cortical spread. Both were equally likely for the first spread event, but local cortical spread was predominant thereafter, suggesting that late degeneration does not advance through long axonal tracts.
