Background: Preclinical studies show that clavulanic acid (CLAV) inhibits cocaine self-administration. This study investigates the effect of CLAV on regions of brain activation in response to cocaine cues during functional magnetic resonance imaging (fMRI) in participants with cocaine use disorder (CUD).

Methods: A double-masked, placebo-controlled clinical trial with thirteen individuals with severe CUD who were randomized to treatment with CLAV (N = 10, 9 completers) 500 mg/day or matched placebo (PBO) (N = 3) for 3 days.

Background: Breast magnetic resonance imaging (MRI) is a very sensitive technique for detection of breast cancer. We report on MRI-guided needle localization for biopsy of abnormalities seen only on MRI.

Methods: A retrospective review was performed of 231 patients with invasive breast cancer or ductal carcinoma-in-situ who had MRI as part of their evaluation and treatment at the University of Pennsylvania between 1992 and 1998.

Background: Sentinel lymph node (SLN) mapping with radioisotope and blue dye is rapidly becoming the standard of care for breast cancer. The optimal location for injection of radioisotope and blue dye is still being investigated. The goal of this study was to determine whether blue dye injection into the subareolar (SA) location localized the same sentinel nodes as the peritumoral (PT) location for patients with breast cancer.
