BACKGROUND AND PURPOSE Maneuvers that distend a lumen facilitate radiographic examinations. In evaluation of the upper aerodigestive tract, Valsalva and phonation maneuvers complement barium fluoroscopy. The current work investigates "puffed-cheek" CT to improve visualization of oral cavity tumors. METHODS Seven patients (ages 17 to 86 years) underwent conventional and puffed-cheek CT. Five h...
OBJECTIVE Simple diagnostic methods can facilitate the diagnosis of COPD, which is a major public health problem. The objective of this study was to investigate the accuracy of clinical variables in the diagnosis of COPD. METHODS Patients with COPD and control subjects were prospectively evaluated by two investigators regarding nine clinical variables. The likelihood ratio for the diagnosis o...
A highly pursed DNA-polymerase has been isolated from normal and regenerating rat liver by differential ultracentrifugation, acid precipitation, ammonium sulfate precipitation, and chromatography on phosphocellulose and on DNAcellulose. The molecular weight of the enzyme is estimated to be 49,000. Enzyme purified in this manner has no detectable terminal transferase, exonuclease, and endonuclea...
AIM To identify risk factors associated with hepatocellular carcinoma (HCC), describe tumor characteristics and treatments pursed for a cohort of individuals with nonalcoholic steatohepatitis (NASH) cirrhosis. METHODS We conducted a retrospective case-control study of a well-characterized cohort of patients among five liver transplant centers with NASH cirrhosis with (cases) and without HCC (...
Previous communications from this laboratory (l-7) have demonstrated that swine maintained on a highly purified diet deficient in pyridoxine develop a severe anemia which is characterized by microcytosis, slight hypochromia, and an increase in polychromatophilia, reticulocytes, and nucleated red cells in the blood. There is a marked hyperferremia, normoblastic bone marrow hyperplasia, myelin de...
We conducted a prospective study to compare the effectiveness of conventional computed tomography (CT) and puffed-cheek CT in detecting the presence and extension of oral cavity malignant tumors. We enrolled 11 patients--5 men and 6 women, aged 32 to 85 years--who had a primary squamous cell carcinoma of the oral cavity. These tumors were located in the floor of the mouth in 4 patients, in the ...
