Biopsy News and Research

RSS

Biopsy is the removal of cells or tissues for examination by a pathologist. The pathologist may study the tissue under a microscope or perform other tests on the cells or tissue. There are many different types of biopsy procedures. The most common types include: (1) incisional biopsy, in which only a sample of tissue is removed; (2) excisional biopsy, in which an entire lump or suspicious area is removed; and (3) needle biopsy, in which a sample of tissue or fluid is removed with a needle. When a wide needle is used, the procedure is called a core biopsy. When a thin needle is used, the procedure is called a fine-needle aspiration biopsy.

New paper evaluates effect of topical benzoyl peroxide on Propionibacterium acnes during shoulder surgery

A new paper to be published in The Journal of Shoulder and Elbow Surgery evaluates the effect that topical benzoyl peroxide (BPO), with chlorhexidine skin preparation, has on the presence of Propionibacterium acnes cultured at the time of shoulder surgery. The authors hypothesized that adding topical BPO, the active ingredient in Clearasil, to the pre-operative skin preparation would reduce the number of positive P. acnes cultures identified during surgery.

Weill Cornell scientists reveal how XBP1 gene can trigger immune responses against ovarian tumors

Ovarian cancer shuts down immune system cells that would otherwise act as a first line of defense against the deadly tumor, Weill Cornell Medical College scientists report today. But a therapy that restores the cells' disease-fighting abilities could provide a powerful new strategy to attack the cancer, which kills more than 14,000 women each year.
