Leukemic blasts from 40 consecutively admitted adults with untreated acute lymphoblastic leukemia (ALL) were examined for myeloid surface antigen expression. Of these, 14 (35%) were reactive with one or more myeloid monoclonal antibodies. Each example of myeloid surface antigen-positive (My+ ALL) met the standard morphologic and cytochemical criteria for(More)
Philadelphia chromosome-positive (Ph1) acute leukemia is a heterogeneous subset of acute leukemia with a poor prognosis. We studied five patients to determine the potential for phenotypic and molecular heterogeneity. Cellular characterization studies included light myeloperoxidase (L-MPO), terminal deoxynucleotidyl transferase (TdT), ultrastructural MPO(More)
Thirty-three patients with chronic lymphocytic leukemia (CLL) with advanced Rai stage (III-IV) or progressive Rai stage (0-II) disease were treated with fludarabine as a single agent. Eleven patients (33%) obtained a complete remission (CR), 13 (39%) a clinical CR with residual nodules as the only evidence of disease (nodular partial remission [PR]), and(More)
Type 2 diabetes is associated with biochemical evidence of low-grade inflammation, and experimental studies have suggested that both insulin and glucose affect inflammatory responses. To determine the effect of in vivo changes in glucose availability and plasma insulin concentrations in humans, we administered 20 U/kg Escherichia coli lipopolysaccharide(More)
Theoretical models suggest that small differences only exist between brain and body temperature in health. Once the brain is injured, brain temperature is generally regarded to rise above body temperature. However, since reports of the magnitude of the temperature gradient between brain and body vary, it is still not clear whether conventional body(More)
Lymph-node and tonsillar biopsies occasionally are obtained from patients with the infectious mononucleosis syndrome secondary to Epstein-Barr viral infection, particularly if the clinical presentation is atypical and a viral etiology is not suspected. The presence of Reed-Sternberg-like cells in infectious mononucleosis resulting in confusion with(More)
Proton magnetic resonance spectroscopy ((1)H MRS) was used to determine brain temperature in healthy volunteers. Partially water-suppressed (1)H MRS data sets were acquired at 3T from four different gray matter (GM)/white matter (WM) volumes. Brain temperatures were determined from the chemical-shift difference between the CH(3) of N-acetyl aspartate (NAA)(More)
Temperature has a major effect on survival in all animal species. Despite wide variations in climate, organ temperature is regulated 'tightly' by homeostatic mechanisms controlling heat production and conservation, as well as heat loss. Although less is known about the temperature of the healthy or injured human brain, mammalian brain homeothermy involves(More)
A primary pancreatic choriocarcinoma was discovered at surgery in a patient with a clinical diagnosis of pancreatic inflammatory pseudocyst. To our knowledge, this is the first example of an extragonadal choriocarcinoma reported as a primary at this site. We consider this neoplasm to be another example of a visceral choriocarcinoma arising from a primary(More)
OBJECTIVE To establish whether there is consensus in the management of body temperature in patients with severe traumatic brain injury (TBI) admitted to hospitals in the United Kingdom and Ireland for neurosurgical intensive care. METHODS Permission was granted from the Society of British Neurosurgeons (SBNS) and the Local Research Ethics Committee to(More)
