In persons who have sustained severe injuries to the cervical spinal cord, electrical stimulation of mixed peripheral nerves in a lower limb can evoke short-latency, bilateral motor responses in muscles of the distal upper limbs; such motor responses have been termed interlimb reflexes. In the present study, we investigated the role that cutaneous(More)
BACKGROUND Although some patients report favorable activity levels late after partial left ventriculectomy (PLV), their exercise physiology has not been well described. METHODS AND RESULTS We performed upright bicycle hemodynamics in 10 patients (9 men) aged 56+/-12 years at 1.7 years after PLV. Ejection fraction was 25+/-4%. Patients biked 10+/-7(More)
INTRODUCTION Anton's syndrome describes the condition in which patients deny their blindness despite objective evidence of visual loss, and moreover confabulate to support their stance. It is a rare extension of cortical blindness in which, in addition to the injury to the occipital cortex, other cortical centres are also affected, with patients typically(More)
No effective treatment exists for primary amyloidosis, a plasma cell dyscrasia characterized by deposition of amyloid fibrils consisting of monoclonal light chains in various organs. TNF-alpha has been implicated in other amyloid disorders; therefore, we used etanercept to treat patients with advanced amyloidosis who had failed other therapies or were(More)
To determine whether upright bicycle exercise could provide useful information about disabling exertional dyspnea in the absence of severe abnormalities (as shown by traditional testing methods), we evaluated 13 such patients. There were 3 men and 10 women with a mean age of 49+/-15 (SD) years. We used pulmonary artery catheterization at rest and during(More)
