Family-based association mapping was used to follow up reports of linkage between reading disability (RD) and a genomic region on chromosome 15q. Using a two-stage approach, we ascertained 101 (stage 1) and 77 (stage 2) parent-proband trios, in which RD was characterized rigorously. In stage 1, a set of eight microsatellite markers spanning the region of(More)
OBJECTIVES To determine the characteristics of phantom limb sensation, phantom limb pain, and residual limb pain, and to evaluate pain-related disability associated with phantom limb pain. DESIGN Retrospective, cross-sectional survey. Six or more months after lower limb amputation, participants (n = 255) completed an amputation pain questionnaire that(More)
OBJECTIVES A systematic review of somatosensory evoked potentials performed early after onset of coma, to predict the likelihood of nonawakening. The pooled results were evaluated for rates of awakening, confidence intervals, and the possibility of rare exceptions. DATA SOURCES Forty-one articles reporting somatosensory evoked potentials in comatose(More)
Two nearly equivalent models of multilevel security are presented. The use of multiple models permits the utilization of each model for purposes where that model is particularly advantageous. In this case, the more general model is simple and easily comprehensible, being more abstract, and is useful for exposition of the meaning of multilevel security. The(More)
STUDY DESIGN This report examines a technique for measurement of axial vertebral rotation using magnetic resonance imaging. OBJECTIVES To assess the reproducibility of three-dimensional magnetic resonance imaging in the measurement of vertebral rotation at individual endplates in patients with adolescent idiopathic scoliosis. SUMMARY OF BACKGROUND DATA(More)
Twenty patients with vocal fold motion impairment were reviewed to correlate the findings of electromyography (EMG) and stroboscopy. The causes of motion impairment were idiopathic, previous surgery with recurrent laryngeal nerve injury, neck and skull base trauma, and neoplasm. The EMG studies were analyzed to assess the status of innervation of the(More)
BACKGROUND AND PURPOSE Previous work implied that the hippocampal cannabinoid system was particularly important in some forms of learning, but direct evidence for this hypothesis is scarce. We therefore assessed the effects of the synthetic cannabinoid HU210 on memory and hippocampal activity. EXPERIMENTAL APPROACH HU210 (100 microg kg(-1)) was(More)
UNLABELLED Although previous research suggests that preamputation pain is a risk factor for pain after amputation, little is known about the association between acute postsurgical pain and chronic amputation-related pain. The current prospective study examined the associations of preamputation pain and acute postamputation pain with chronic(More)
Biopsychosocial models of chronic pain hypothesize a role for psychological and environmental factors in adjustment to chronic pain. To test the utility of such models for understanding phantom limb pain, 61 persons with recent amputations were administered measures of average phantom limb pain intensity, pain interference, depression, pain coping use, pain(More)
Linkage disequilibrium (LD) mapping was used to follow up reports of linkage between reading disability (RD) and an 18 cM region of chromosome 6p21.3-22. Using a two-stage approach, we tested for association between RD and 22 microsatellite markers in two independent samples of 101 (Stage 1) and 77 (Stage 2) parent/proband trios in which RD was rigorously(More)
