PURPOSE The validity of clinical perimetry for evaluation of the pathology of glaucoma is based on correlated losses in retinal ganglion cells and visual sensitivity, but procedures to quantify neural losses from visual field defects have not been developed. The purpose of the present study was to investigate the neural and sensitivity losses from(More)
BACKGROUND Multivitamin and mineral supplements are the most commonly used dietary supplements in the United States. PURPOSE To synthesize studies on the efficacy and safety of multivitamin/mineral supplement use in primary prevention of cancer and chronic disease in the general population. DATA SOURCES English-language literature search of the MEDLINE,(More)
Electromyography was done in patients at the C6 level of quadriplegia after transfer of the brachioradialis to the flexor pollicis longus to restore lateral pinch and transfer of the posterior deltoid to the triceps to restore elbow extension. The relationship of the integrated electromyogram to pinch force during a graduated isometric contraction enabled(More)
The energy expenditure and gait characteristics of eleven subjects who had a unilateral arthrodesis of the hip and ten subjects who had a unilateral arthrodesis of the ankle were measured during a twenty-minute walking trial. Oxygen consumption was determined and heart rate, respiratory rate, and step frequency were monitored. The average walking speed for(More)
Graft-vs-host disease (GVHD) is a potentially treatable cause of progressive neurologic decline after bone marrow transplantation (BMT). The authors present histologic confirmation of CNS granulomatous angiitis in a child with chronic GVHD after BMT. Since cranial MRI showed only nonspecific findings, CNS vasculitis associated with GVHD after BMT may be(More)
OBJECTIVES To review and synthesize published literature on the efficacy of multivitamin/mineral supplements and certain single nutrient supplements in the primary prevention of chronic disease in the general adult population, and on the safety of multivitamin/mineral supplements and certain single nutrient supplements, likely to be included in(More)
Inclusion body myositis is an inflammatory myopathy in which dysphagia has been considered a rare finding. However, recent literature finds dysphagia an increasingly common symptom as more cases of inclusion body myositis are identified. Unlike some inflammatory myopathic disorders, inclusion body myositis is resistant to treatment with corticosteroids, and(More)
AIMS This study investigated the development of the fallopian canal with particular reference to the mode of ossification and dehiscences, sites of incomplete closure around the facial nerve. BACKGROUND The precise sequence of events surrounding ossification of the tissues around the facial nerve is uncertain. Incomplete ossification results in dehiscence(More)
OBJECTIVE We evaluated central venous catheter motion causing misinterpretation of catheter tip location in pediatric patients and in an experimental model. MATERIALS AND METHODS After the recognition of clinically significant catheter motion in 12 randomly selected patients, we conducted a prospective 2-month study of chest radiographs in our pediatric(More)
