Navy funds minimally-invasive surgery institute

Scientists at Cedars-Sinai Medical Center will work closely with clinicians to develop a new generation of minimally invasive tools and techniques at the hospital's newly created Minimally Invasive Surgical Technology Institute. The Institute was established through a $1 million grant awarded by the Office of Naval Research in November 2002 and internal contributions from Cedars-Sinai. Under the direction of biophysicist and Fulbright scholar Daniel L. Farkas, Ph.D., the Institute brings together a scientific research group, a pre-clinical facility and a clinical assessment team, all focusing collaboratively on the development, testing and introduction of noninvasive technologies into everyday surgical practice.

Surgeon uses new method to remove pituitary tumors

Removing pituitary tumors through the nasal cavity rather than using the classic approach beneath the upper lip offers patients a minimally invasive alternative with similar results, less discomfort and faster recovery, a new UCLA study indicates. The findings, published in the February 2003 edition of the peer-reviewed Journal of Neurosurgery, quantify the advantages of the direct endonasal approach over the sublabial procedure, regarded as the surgical standard for more than 40 years.

Brain's perception depends upon the source of cues, researchers find

When the human brain is presented with conflicting information about an object from different senses, it finds a remarkably efficient way to sort out the discrepancies, according to new research conducted at the University of California, Berkeley. The researchers found that when sensory cues from the hands and eyes differ from one another, the brain effectively splits the difference to produce a single mental image. The researchers describe the middle ground as a "weighted average" because in any given individual, one sense may have more influence than the other. When the discrepancy is too large, however, the brain reverts to information from a single cue - from the eyes, for instance - to make a judgment about what is true.

New Technique Lets Doctors Examine Milk Ducts for Breast Problems

A new technique enables doctors to directly examine the lining of milk ducts in the breast for early signs of cancer and other abnormalities, according to research at Washington University School of Medicine in St. Louis. The researchers used the technique, known as ductoscopy, to detect breast abnormalities in women with a condition called pathologic nipple discharge (PND).

Test could reduce need for biopsies in prostate disease

Just a drop, that's all we need Men who test positive for elevated prostate specific antigen (PSA) levels sometimes freak out because they think it means they have cancer. To find out, a surgeon will often perform a biopsy. But researchers from the National Cancer Institute and the Food and Drug Administration report that a new test using a single drop of blood could help distinguish between prostate cancer and benign conditions. The trick is identifying patterns of proteins found in patients' blood serum.
