    Eva Pressman Appointed Chair of Obstetrics and Gynecology

    Eva K. Pressman, M.D., has been selected as Henry A. Thiede Professor and Chair of the University of Rochester's Department of Obstetrics and Gynecology. Pressman is the first woman to chair the department, succeeding James R. Woods, M.D., who stepped down in June 2013 after 10 years as chair.

    Dr. Pressman's demonstrated leadership in women's health, on both local and national levels, has prepared her well to meet the challenges and seize the opportunities that lie ahead for our Department of Obstetrics and Gynecology, said Bradford C. Berk, M.D., Ph.D., Medical Center CEO. We look forward with excitement to the vision and expertise she brings to her new role as chair.

    Pressman earned her bachelor of science from Brown University and her medical degree from Duke University School of Medicine, where she was elected to Alpha Omega Alpha Honor Society. She completed residency training in Ob/Gyn as well as a fellowship in Maternal Fetal Medicine at Johns Hopkins University. I am proud to continue the legacy of leadership in Obstetrics and Gynecology at the University of Rochester. Pressman said. Dating back to the discovery of progesterone by Dr. Willard Allen in 1930, this institution has remained at the forefront of women's health care for generations. I look forward to working with our talented faculty and staff to deliver the best, safest and most compassionate care and expanding the field of Obstetrics and Gynecology through education, research and community outreach. Pressman's clinical practice and research have focused on medical complications of pregnancy, preterm birth, premature rupture of membranes, and obstetrical ultrasound.

    With her career-long commitment to maternal health, Dr. Pressman has an established track record in both her clinical practice and research efforts that makes the health of mothers and babies a priority, said Steve Goldstein, president and CEO of Strong Memorial Hospital and Highland Hospital. As department chair, Eva's leadership and commitment will extend to all areas of Ob/Gyn, to the benefit of our organization as well as the health of women throughout our community and region.

    Maria Helguera Appointed Wedd Visiting Professor

    Maria Helguera, Ph.D. was appointed the Wedd Visiting Professor of Pharmacology and Physiology for the 2013-2014 academic year. Dr. Helguera is an Associate Professor in the Chester Carlson Center for Imaging Sciences at RIT, and a long-standing member of the RCBU. Dr. Helguera's research is dedicated to biomedical and materials multimodal imaging.

    Dr. Helguera's research is focused primarily on developing novel ultrasound materials characterization techniques for both biological and non-biological materials. Recently, Dr. Helguera, Dr. Denise Hocking (UR Pharmacology and Physiology), and Dr. Diane Dalecki (UR BME) have established a productive collaboration focused on developing quantitative ultrasound tissue characterization techniques for applications in tissue engineering. Current efforts of the team are focused on developing spectral backscatter techniques to quantify cellular and acellular engineered hydrogels, and utilizing novel image processing techniques to quantitatively characterize vascular morphology in three-dimensional tissue engineered constructs.

    Dr. Helguera has also begun to develop a new collaboration with Dr. Angela Glading in the Department of Pharmacology and Physiology. Dr. Glading and Dr. Helguera aim to develop new imaging techniques that can characterize normal and abnormal vasculature in vivo. The Wedd Visiting Professorship will provide a wonderful opportunity for Dr. Helguera to further these multidisciplinary collaborative efforts, and expose other researchers in the Department of Pharmacology and Physiology to her expertise in imaging science.

    RCBU Members Develop New Way to Detect Prostate Cancer

    RCBU members Vikram Dogra and Navalgund Rao received a patent earlier this year for the new technology, called photoacoustic imaging. Their system uses rapid bursts of laser light to bombard a specific region of the body, with the resulting sound waves captured to create a series of high resolution images. This new technique could make a significant impact when compared to the traditional means of detecting and diagnosing prostate cancer.

    Dr. Dogra, whose specialty is diagnostic radiology, said that the effectiveness of these traditional techniques is limited. Almost half of PSA screened patients get a false-positive from the ultrasound, and biopsies miss about 30 percent of cancer cases.

    We can use ultrasound or even MRI, but we simply can't see the prostate very well, Dogra explained. When we go to biopsy, we're often not seeing where the cancer is. We take six samples from each side, but we still might not find the cancer.

    That's the beauty of what we are trying to do, Dogra said. This new technology will most likely eliminate the need for doing biopsies completely, or at least allow us to do only a targeted biopsy.
