OBJECTIVES/HYPOTHESIS The aim was to compare the value of 18-Fluoro-Deoxyglucose (18F-FDG) positron emission tomography (PET)/computed tomography (CT) regarding contralateral lymph node (LN) metastasis in the neck. STUDY DESIGN Retrospective analysis of 61 patients staged by 18F-FDG-PET/CT. METHODS Cytology/histology served as a reference standard.(More)
Human prion diseases are devastating and incurable, but are very rare. Fears that the bovine spongiform encephalopathy epizootic would lead to a large epidemic of its presumed human counterpart, variant Creutzfeldt-Jakob disease (vCJD), have not been realised. Yet a feeling of uncertainty prevails in the general public and in the biomedical world. The lack(More)
BACKGROUND Sentinel node biopsy (SNB) has been proposed for staging of the cN0 neck in early oral/oropharyngeal squamous cell carcinomas (SCC). Because SNB is a minimally invasive procedure, it is thought to be associated with less morbidity than elective neck dissection. METHODS Sixty-two consecutive patients were included from 2000 to 2009. Two groups(More)
OBJECTIVE The goal of this study was to describe the incidence, treatment, and outcomes of osteosarcomas in the head and neck over 26 years in the province of Alberta, Canada. DESIGN Retrospective analysis of 14 patients identified and treated in Alberta between 1974 and 1999. Overall and disease-specific survival were the most important outcomes of(More)
OBJECTIVES To determine accuracy and intertest agreement of preoperative fine-needle aspiration cytology (FNAC) and intraoperative frozen-section analysis (FS) findings in thyroid surgery, and to assess the influence of intraoperative FS findings on decision making and the utility of FS in thyroid surgery. DESIGN Retrospective analysis. The results of(More)
OBJECTIVE Follow-up of patients with oral cavity squamous cell carcinoma (OCSCC) after tumor resection and reconstruction with tissue transfer is challenging. We compared contrast-enhanced computed tomography (ceCT), (18) F-fluorodeoxyglucose-positron emission tomography combined with noncontrast enhanced CT ((18) F-FDG-PET/CT), and (18) F-FDG-PET combined(More)
UNLABELLED Considering PET/MR imaging as a whole-body staging tool, scan time restrictions in a single body area are mandatory for the cost-effective clinical operation of an integrated multimodality scanner setting. It has to be considered that (18)F-FDG already acts as a contrast agent and that under certain circumstances MR contrast may not yield(More)
Before, during, and after allogeneic hematopoietic stem cell transplantation (allo-HSCT), patients experience considerable physical and psychologic distress. Besides graft-versus-host disease and infections, reduced physical performance and high levels of fatigue affect patients' quality of life. This multicenter randomized controlled trial examined the(More)
Prion pathogenesis following oral exposure is thought to involve gut-associated lymphatic tissue, which includes Peyer's patches (PPs) and M cells. Recruitment of activated B lymphocytes to PPs requires alpha(4)beta(7) integrin; PPs of beta 7(-/-) mice are normal in number but are atrophic and almost entirely devoid of B cells. Here we report that minimal(More)
Even when the procedures are successful, patients experience considerable physical, psychological and psychosocial stress before, during and after hematopoietic stem cell transplantation (HSCT). Physical exercise therapy constitutes a potentially promising intervention to reduce such stress within the framework of HSCT because of its multidimensional(More)
