Bone marrow plasma cells (PCs) from 74 patients with newly diagnosed multiple myeloma (MM), 5 with monoclonal gammopathy of undetermined significance (MGUS), and 31 healthy volunteers (normal PCs) were purified by CD138(+) selection. Gene expression of purified PCs and 7 MM cell lines were profiled using high-density oligonucleotide microarrays(More)
OBJECTIVE Sialoscopy has developed into an important diagnostic and therapeutic tool for diseases of the major salivary glands. STUDY DESIGN AND SETTING We evaluated 103 patients with chronic swelling of the major salivary glands. Routine diagnostic measures revealed no clear diagnosis. The findings of 109 sialoscopies are described. A semi-rigid(More)
To identify genes linked to normal plasma cell (PC) differentiation and to classify multiple myeloma (MM) with respect to the expression patterns of these genes, we analyzed global mRNA expression in CD19-enriched B cells (BCs) from 7 tonsils, CD138-enriched PCs from 11 tonsils, 31 normal bone marrow samples, and 74 MM bone marrow samples using microarrays(More)
BACKGROUND Minimally invasive endoscopic and microscopic procedures represent state of the art paranasal sinus surgery techniques in both diagnostic and surgical fields. To combine favorable aspects of both techniques, we evaluated the clinical applicability and effectiveness of multifunctional microendoscopes, providing multiple features to ensure highest(More)
Multiple myeloma (MM) is a hypoproliferative malignancy yielding informative karyotypes in no more than 30% of newly diagnosed cases. Although cytogenetic and molecular deletion of chromosome 13 is associated with poor prognosis, a MM tumor suppressor gene (TSG) has not been identified. To localize a minimal deleted region of chromosome 13, clonotypic(More)
We compared gene expression in purified tumor cells from untreated patients with chronic lymphocytic (CLL) (n=24) and newly diagnosed multiple myeloma (MM) (n=29) using the Affymetrix HuGeneFL microarray with probes for approximately 6800 genes. Hierarchical clustering analysis showed that CLL and MM have distinct expression profiles (class prediction).(More)
Sperm protein 17 (Sp17) is a protein recently identified as a novel cancer-testis (CT) antigen in multiple myeloma (MM). Because this tumor antigen demonstrates a very restricted normal tissue expression, Sp17 may be an excellent target for tumor vaccine of MM. In this study, we determined the ability to generate Sp17-specific HLA class I-restricted(More)
We recently found that sperm protein 17 (Sp17), a spermatozoa-restricted protein, is aberrantly expressed on the tumor cells in patients with multiple myeloma (MM). It may therefore be possible to generate donor-derived Sp17-specific CTL for administration following allogeneic stem cell transplant to augment graft-versus-myeloma (GVM) effect without(More)
A 47-year old man presented with a five-year history of fluctuating hearing impairment in the left ear. There was no tinnitus or vertigo. Imaging studies demonstrated a contrast-enhancing cerebellopontine angle mass in the left internal auditory canal. Surgically the lesion was attached to the cochlear nerve. Pathological evaluation revealed what is best(More)
Frameless stereotactic procedures crucially depend on the firmness of immobilization. Once registered, shifting of the patient leads to inaccuracy, and the patient registration has to be realigned. To overcome the drawbacks of conventional invasive fixation for neurosurgery and the widely accepted fixation with surgical tape in ENT, the Vogele-Bale-Hohner(More)
