Lemierre's syndrome (LS) is a rare, but a life-threatening complication of an oropharyngeal infection. Combinations of fever, pharyngitis, dysphagia, odynophagia, or oropharyngeal swelling are common presenting symptoms. Infection of the lateral pharyngeal space may result in thrombosis of the internal jugular vein, subsequent metastatic complications (e.g., lung abscesses, septic arthritis), a...

OBJECTIVES To analyze the distribution of lymph node metastases in patients with oropharyngeal squamous cell carcinoma and improve the rationale for elective treatment of the neck. DESIGN AND SETTING Retrospective cohort study of patients evaluated from 1990 to 1998 in a tertiary cancer care center. PATIENTS The 81 consecutive patients who were identified from the hospital database. Patient...

A dam spillway is a hydraulic structure that appropriately and safely diverts the outflow to downstream, so that the dam stability and passing of flood flows can be guaranteed. Compared to straight crest spillway, an Ogee spillway with curvature in plan in a fixed-width can pass more flow. Therefore under the low hydraulic heads and the need for a smaller place in plane, they are considered as ...

Genetically altered mice are useful to understand cardiac physiology. Myocardial contrast echocardiography (MCE) assesses myocardial perfusion in humans. We hypothesized it could evaluate murine myocardial perfusion before and after acute coronary ligation. MCE was performed before and after this experimental myocardial infarction (MI) in anesthetized mice by intravenous injection of contrast m...

OBJECTIVE As in Part I, to elucidate the role of fluid mechanical factors in the localized genesis and development of atherosclerotic lesions in man, here in the abdominal aorta. METHODS Flow patterns and preferred sites of atherosclerotic lesions in the aorta were studied in detail using the same isolated transparent aortic trees prepared from humans postmortem and the flow visualization and...

Abstract Lateral forces (wind, seismic) generated in RC buildings are major design criteria against structural collapse. Shear walls offer effective ways to provide resistance such lateral loads. The present study investigates the drift and defection control of symmetrical by providing core corner shear walls. Different limiting were determined four seismic zones (Zone-1 Zone-4) Bangladesh, bas...

UNLABELLED In 2-dimensional cardiac PET/CT, misregistration between the PET and CT images due to respiratory and cardiac motion causes tracer uptake to appear substantially reduced. The resolution and quality of the images have been considerably improved by the use of 3-dimensional (3D) PET acquisitions. In the current study, we investigated the impact that misregistration between PET and CT im...
