Medical imaging: The good, the bad and the ugly

In the political minefield of healthcare reform, medical imaging has emerged as a microcosm of this contentious debate. Congress has been charged with a high stakes, high wire balancing act: to create a bill preserving quality and access while trimming unethical and unnecessary spending. Medical imaging represents such a challenge, with its undeniable benefits tainted by inappropriate use.

Giant pituitary adenoma can be safely removed through nasal route

It’s even worse than being told you have a brain tumor: having a tumor so large, it’s in a category all its own. Giant pituitary adenoma is a so-called “benign” tumor that can cause visual loss and impair many of the body’s most basic functions. But fortunately, even the largest of these giant tumors—which can grow to the size of an egg and invade nearby structures--can be treated effectively using a multimodality approach starting with minimally invasive surgery through the nose, according to a new study at the John Wayne Cancer Institute at Saint John’s Health Center.

Oxygen treatment may speed memory loss associated with Alzheimer's

A 65-year-old women goes into the hospital for routine hip surgery. Six months later, she develops memory loss and is later diagnosed with Alzheimer's Disease. Just a coincidence? Researchers at the University of South Florida and Vanderbilt University don't think so. They suspect that the culprit precipitating Alzheimer's disease in the elderly women may be a routine administration of high concentrations of oxygen for several hours during, or following, surgery - a hypothesis borne out in a recent animal model study.

New tool for virtual surgery simulates blood flow - helps plan child's delicate heart surgery

Researchers at the Georgia Institute of Technology, collaborating with pediatric cardiologists and surgeons at The Children's Hospital of Philadelphia, have developed a tool for virtual surgery that allows heart surgeons to view the predicted effects of different surgical approaches. By manipulating three-dimensional cardiac magnetic resonance images of a patient's specific anatomy, physicians can compare how alternative approaches affect blood flow and expected outcomes, and can select the best approach for each patient before entering the operating room.

Predictors of disease behavior change in patients with Crohn's disease

Using the Vienna classification system, it has been shown in clinic-based cohorts that there can be a significant change in disease behavior over time, whereas disease location remains relatively stable. Clinical and environmental factors as well as medical therapy might be relevant in predicting disease behavior change in patients with CD.

STAT3 is required for proliferation and maintenance of multipotency in glioblastoma stem cells

In a study published online in advance of print in Stem Cells, Tufts researchers report that the STAT3 gene regulates cancer stem cells in brain cancer. Cancer stem cells have many characteristics of stem cells and are thought to be the cells that drive tumor formation. The researchers report that STAT3 could become a target for cancer therapy, specifically in Glioblastoma multiforme (GBM), a type of malignant and aggressive brain tumor.

New molecule blocks lymphangiogenesis

Researchers in the laboratory of Dr. Jayakrishna Ambati at the University of Kentucky have discovered the first naturally occurring molecule that selectively blocks lymphatic vessel growth. In an article in the Aug. 9, 2009 online edition of Nature Medicine, they report the identification of a new molecule known as soluble VEGFR-2 that blocks lymphangiogenesis - the growth of lymphatics - but not blood vessel growth.
