Introduction Angiosarcoma of the head and neck is a rare vascular sarcoma associated with high rates of local recurrence and distant metastasis and a poor prognosis. Objective We describe our experience treating patients with angiosarcoma of the head and neck to evaluate the outcomes, patterns of failure, and current treatments. Methods We identified six(More)
Background: Synovial Sarcoma of the head and neck is a rare, aggressive malignancy with a poor prognosis. This study reports the clinical course and management of 5 patients presenting with synovial sarcoma of the head and neck at our institution to evaluate the outcomes, patterns of failure, and current treatments. Methods: We identified 5 patients(More)
Activated macrophages are thought to kill Trypanosoma cruzi, which lack catalase, by the generation of hydrogen peroxide. We investigated triggering of the respiratory burst of activated macrophages induced by phagocytosis of virulent T. cruzi, bloodform trypomastigotes, amastigotes obtained from spleens, and tissue culture organisms; and of relatively(More)
Parenteral interferon-gamma (IFN-gamma) activates murine macrophages to inhibit Trypanosoma cruzi multiplication and diminishes parasitemia and mortality in acute infection. To investigate the role of endogenous IFN-gamma in acute infection, monoclonal antibody to IFN-gamma was injected intraperitoneally into mice. The 6250 neutralizing units given 24 and(More)
Glutamine synthetase (GS) from bovine retina was purified to apparent homogeneity by ammonium sulfate fractionation followed by Sephacryl S-200, hydroxylapatite, and Sephadex G-150 chromatography. The purified enzyme showed a single band on polyacrylamide gel electrophoresis. Based on the purification data, retinal GS was shown to be approximately 2% of the(More)
Explants of 13 different organs obtained from C3H/HEN, Swiss-Webster, and C57Bl/6 mice chronically infected with Trypanosoma cruzi (Y strain) were cocultivated with mouse embryo fibroblasts to determine the organs that contain T. cruzi during the chronic infection. Explant cultures frequently yielded T. cruzi as late as 12 months after infection. Spleen and(More)
To determine if exogenous gamma interferon is effective in immunosuppressed mice infected with Trypanosoma cruzi, recombinant murine gamma interferon was administered to cyclosporin-treated mice with either acute or chronic T. cruzi infection. Gamma interferon significantly decreased parasitemia and prevented death in acutely infected mice. Parasitemias and(More)
INTRODUCTION Computed tomography (CT), combined positron emitted tomography and CT (PET/CT), and magnetic resonance imaging (MRI) are commonly used in head and neck radiation planning. Hybrid PET/MRI has garnered attention for potential added value in cancer staging and treatment planning. Herein, we compare PET/MRI vs. planning CT for head and neck cancer(More)
BACKGROUND It is unclear whether bone invasion in small oral cavity squamous cell carcinomas (OCSCC) results in worse prognosis. METHODS Two hundred fifty-four patients with OCSCC were identified and divided into 3 cohorts: (1) ≤4 cm with no bone invasion; (2) ≤4 cm with bone invasion; and (3) ≥4 cm or other factors (eg, skin invasion, deep muscle(More)
A majority of adults without evidence of exposure to vesicular stomatitis virus (VSV) have serum IgG antibodies that interact with pro-inflammatory TLR7 in the presence of VSV, and enhance several aspects of VSV-induced IFN-alpha production. Enhancing IgG antibody enables human PBMC to make IFN-alpha more rapidly and in higher titers in response to a broad(More)
