Stereotaxic needle core biopsy of breast lesions using a regular mammographic table with an adaptable stereotaxic device.

Objective: Fine-needle aspiration and stereotaxic needle core biopsy (SNCB) are techniques used in the workup of breast lesions suggestive of cancer. Many surgeons are reluctant to rely on fine needle results, and until now, SNCB could be done only with a dedicated biopsy table. Our study was done to determine whether SNCB could be performed safely and effectively with a regular mammography unit and an added stereotaxic device.

Immunologic changes after blood transfusion in patients undergoing vascular surgery.

Immunologic changes after blood transfusions cannot be studied ethically in normal individuals. We therefore studied two comparable groups of patients with atherosclerotic cardiovascular disease who received similar drug treatment and experienced a similar degree of surgical trauma, except that one group received an average of 2.5 units of packed red cells at one time period during surgery.
