Lateralized human cortical activity for shifting visuospatial attention and initiating saccades. J. Neurophysiol. 80: 2900-2910, 1998. The relation between shifts of visual attention and saccade preparation was investigated by studying their electrophysiological correlates in human scalp-recorded electroencephalogram (EEG). Participants had to make saccades(More)
This study determined the in situ detection rate of polymerase chain reaction (PCR)-amplified human immunodeficiency virus type 1 (HIV-1) DNA and RNA in lymph nodes and peripheral blood CD4+ cells in six patients with asymptomatic HIV-1 infection and from six people who died of advanced AIDS. The lymph nodes of patients with asymptomatic infection showed(More)
BACKGROUND The objective of this study was to determine whether a nonabsorbable antibiotic lozenge could alleviate radiation-induced oral mucositis. METHODS Patients scheduled to receive radiation therapy to more than one-third of the oral cavity mucosa were selected for the study. After stratification, patients were randomized to receive either a(More)
Pathologic rupture of the spleen in hematologic malignancies is rare. We present two cases of splenic rupture which occurred in a man with a secondary high-grade non-Hodgkin's lymphoma and a woman with chronic lymphocytic leukemia (CLL). In a review of the literature, we have been able to identify 136 cases of pathologic splenic rupture since 1861; 34% have(More)
PURPOSE Considerable pilot data and clinical experience suggested that an aloe vera gel might help to prevent radiation therapy-induced dermatitis. METHODS AND MATERIALS Two Phase III randomized trials were conducted. The first one was double blinded, utilized a placebo gel, and involved 194 women receiving breast or chest wall irradiation. The second(More)
PURPOSE To evaluate whether cisplatin-based chemotherapy (gemcitabine, vinorelbine, and cisplatin [GVP]) prolongs overall survival in comparison to cisplatin-free chemotherapy (gemcitabine and vinorelbine [GV]) as first-line treatment in patients with advanced non-small-cell lung cancer (NSCLC). PATIENTS AND METHODS Between September 1999 and June 2001,(More)
To determine if in vivo binding specificities of monoclonal antibodies to tumor nodules would reflect in vitro antibody specificities as determined by radioimmunoassay, two monoclonal antibodies were selected for imaging of human tumor xenografts in nude mice. By in vitro radioimmunoassay, antibody 436 binds to the M20 melanoma cell line, but not to the P3(More)
Algorithms for the differential diagnosis of anemias are commonly based on suspected incidences and simple laboratory parameters. Especially microcytic anemias are diagnosed using algorithms created in Mediterranean or Northern American regions. In a West German region we observe relatively high diagnostic uncertainty regarding common forms of anemias. As a(More)
Protein C and protein S deficiencies increase the risk of venous thrombosis and pulmonary embolism, but their role in arterial thrombosis or embolism is controversial. We describe cerebral ischemia in two young women in a family with inherited deficiencies of both proteins C and S and provide evidence that a combined deficiency of proteins C and S may be a(More)
Antibodies against factor VIII occur in about 15-35% of hemophilia A patients and induce refractoriness to factor VIII substitution. In most cases, these antibodies are of the IgG class. Strategies to avoid or to treat such inhibitors are controversial. In very rare cases, factor VIII inhibitors also develop in nonhemophilic patients. Although there are(More)
