Osteomyelitis beneath pressure sores.

Twenty-eight pressure sores were evaluated prospectively. Osteomyelitis was reported histologically in nine of 28 bones and pressure-related changes were reported in 14 bones. Roentgenograms suggested the presence of osteomyelitis in four instances of histologically proved osteomyelitis.

Left ventricular function in hospitalized geriatric patients.

Left ventricular ejection fraction was measured by gated wall motion in 62 patients, 75 years old or older, admitted to a Geriatric Acute Assessment Ward. From this group, 42 patients not taking digitalis or other cardioactive medication were selected for analysis. Thirty of them had clinically identifiable heart disease, whereas 12 did not.

Selective uptake of 75Se-selenomethionine by thymoma with pre red cell aplasia.

Red cell aplasia and an enlarging anterior mediastinal mass developed in a patient being followed for thyroid carcinoma. Differential diagnosis included thymoma and metastatic thyroid carcinoma. Preoperative scanning demonstrated significant uptake of 75Se-selenomethionine whereas 67Ga-galiium citrate failed to visualize the mass.
