IMPORTANCE Venous thromboembolism (VTE) is associated with significant morbidity and mortality in surgery patients, but little data exist on the incidence of VTE in head and neck cancer surgical patients. OBJECTIVE To determine the incidence of VTE in postoperative patients with head and neck cancer. DESIGN, SETTING, AND PARTICIPANTS A prospective study(More)
BACKGROUND The measurement of jejunal disaccharidases is used by several gastroenterologists when investigating suspected small-bowel disease. The clinical value of this analysis is assessed. METHOD The histology and disaccharidase results in 1585 jejunal biopsy specimens were reviewed retrospectively. RESULTS Disaccharidase and histology results(More)
OBJECTIVES To prospectively determine the incidence of venous thromboembolism (VTE) following major head and neck surgery. At the midpoint of enrollment, an interim analysis was performed to determine if it was ethical to continue this study as an observational study without routine anticoagulation. DESIGN Prospective, observational cohort study. (More)
We investigated the feasibility of using nulling interferometry techniques in the stratosphere to search for extra-solar planets. Studies have shown wavefront distortions from atmospheric turbulence to be too large to obtain clear ground-based images. Wavefront errors caused by atmospheric turbulence in the stratosphere are on the scale of 1 angstrom [4],(More)
The global eradication of poliomyelitis will require substantial changes in immunization practices. One of the proposed scenarios includes cessation of vaccination with live oral poliovirus vaccine (OPV) and the creation of an OPV stockpile for emergency response in case of the reintroduction of poliovirus into circulation. We describe here a retrospective(More)
