Direct magnificaiton of the hands of 44 patients on maintenance hemodialysis showed that the earliest unequivocal changes of renal osteodystrophy occur in the tufts. Some workers made a similar observation, but no previous objective study confirmed or refuted the sensitivity of the tufts in the diagnosis of renal osteodystrophy. The macroradiograph is(More)
Fifty-five computed tomography scans in 27 patients with systemic lupus erythematosus were reviewed. The most frequent indication for scanning was suspected intraabdominal sepsis, and the most frequent finding was mild lymphadenopathy. Renal abnormalities were: subcapsular hematoma, focal defects, overall enlargement, and diminution of size. Other findings(More)
Review of 84 computed tomographic (CT) scans in leukemic patients demonstrated a wide spectrum of abnormalities. Findings caused by leukemia were lymphadenopathy, visceral enlargement, focal defects, and tissue infiltration. Hemorrhage was by far the most common complication and could usually be characterized on the noncontrast CT scan. The distinction(More)
A radioimmunoassay was developed capable of determining Aroclor 1260 in milk at levels of from 20 to 80 ppb and in blood from 2 to 16 ppb. The values obtained by radioimmunoassay correlate well with those determined by gas-liquid chromatography (r2 = 0.96 for milk and 0.99 for blood) but were lower. Antiserum was produced in rabbits and was specific for(More)
