BACKGROUND Acute traumatic coagulopathy (ATC) is an impairment of hemostasis that occurs early after injury and is associated with a 4-fold higher mortality, increased transfusion requirements and organ failure. OBJECTIVES The purpose of the present study was to develop a clinically relevant definition of ATC and understand the etiology of this endogenous(More)
Neuroimaging and electrophysiological studies have shown that executed action and motor imagery activate common neuronal substrates, leading to the hypothesis that movement preparation and motor imagery are functionally equivalent processes. This study further tested the functional equivalence hypothesis by determining whether electrocortical patterns(More)
A closed-loop model of motor control predicts that central deafferentation should disrupt cortical motor processes when imagining movements of paralyzed limbs. To test this prediction, event-related potentials (ERP) were recorded from the supplementary motor area and the primary sensorimotor area in individuals with paraplegia or quadriplegia as well as(More)
Autoimmune phenomena may complicate the course of myelodysplastic syndromes (MDS) but large vessel arteritis is a rare event. We report a case of large vessel arteritis in a patient with MDS. A 62-year-old male presented with thrombocytopenia and was diagnosed with low-risk MDS, (<5% blasts in his bone marrow and a normal karyotype). Shortly thereafter he(More)
BACKGROUND Spontaneous bacterial peritonitis is frequent among cirrhotic patients, associated with significant morbidity and mortality. Selective intestinal decontamination employing antibiotics is a proposed prophylactic measure. While data regarding this modality among cirrhotic patients with gastrointestinal bleeding exist, there is insufficient data(More)
Visuospatial information processing has been shown to be particularly sensitive to acute alcohol intoxication and chronic alcohol abuse. This study extended previous studies by determining if recently detoxified alcoholics recover visuospatial processing after long-term abstinence. If visuospatial function returns to the level displayed by intoxicated(More)
In an effort to understand the mechanisms involved in dysesthetic pain syndrome (DPS) in spinal cord injury (SCI) patients, four groups of 13 subjects each--SCI subjects with DPS, SCI subjects without pain, chronic low back pain subjects, and control subjects--were examined for sensory detection and pain thresholds at forearm, neck, and rostral trunk areas.(More)
OBJECTIVE Of the many factors that affect the occurrence of and rehabilitation from spinal cord injury, alcohol use and abuse are particularly prominent. Persons with a family history of alcoholism are at greater risk for alcohol abuse and alcoholism. Preliminary data show a much higher than normal proportion of these persons in the spinal cord injured(More)
Laparoscopic sleeve gastrectomy (LSG) has become a common surgical procedure, yet there is no consensus on what bougie size is best for LSG. We reviewed the literature and assessed the relationship between the size of bougie used and the incidence of leak as well as weight loss parameters. We wanted to determine if there is an ideal bougie size for LSG. A(More)
Eleven chronic low back pain (CLBP) patients were compared with eleven age-matched controls to different postures and stress while measuring paraspinal and frontalis EMG activity, heart rate and galvanic skin response. Contrary to current theory, results indicate that the CLBP group exhibited similar or significantly less paraspinal muscle activity than the(More)
