The aim of this study was to investigate the accuracy of imprint cytology (IC) of breast core biopsy under ultrasound guidance and to assess the value of a rapid on-site preliminary diagnosis of breast lesions. A total of 437 breast core needle biopsies under ultrasound guidance with touch imprint cytology, histology, and final diagnosis were reviewed. These cases were collected from archived files at our institution.

In the past several years, breast-conservation therapy has provided an alternative to mastectomy. In order to reduce the subsequent local tumor recurrence, it is critical that all the measures are in place to find the residual foci of occult microscopic tumor at the time of the initial lumpectomy procedure. An accepted method to evaluate the lumpectomy margins for presence of residual tumor is the use of imprint cytology (also called touch-prep), which is assessment of the presence or absence of the tumor cells by cytological preparation.

Fine-needle aspiration biopsy (FNAB) of breast is a minimally invasive sampling procedure with a proven value in the initial evaluation of patients with palpable breast lesions. FNAB is a simple, cost-effective, and relatively nontraumatic procedure that has replaced open surgical biopsy in majority of academic institutions across the world. There are, however, inherent limitations in the ability of FNAB to reliably diagnose small percentage of cases that are difficult to diagnose by cytomorphology alone and require excisional biopsy.

Background: Evidence suggests that the rate at which intravenous anesthetics are infused may influence their plasma-effect site equilibration. The authors used five different rates of propofol administration to test the hypothesis that different sedation endpoints occur at the same effect site propofol concentration, independent of the infusion rate. The authors concurrently evaluated the automated responsiveness monitor (ARM) against other sedation measures and the propofol effect site concentration.

Background: German anesthesiologists have long used transcutaneous electrical stimulation of an acupuncture point near the tragus to reduce anesthetic requirement in unblinded and uncontrolled trials. This is known as auricular electrically stimulated analgesia. The authors therefore tested the hypothesis that auricular electrically stimulated analgesia reduces anesthetic requirement.
