Cure for cancer one step closer

...sley Hospital alone had almost 2000 cancer related surgeries in 2004. The Queensland Government contributed $1.42 million towards the construction of the Tissue Bank through the Smart State Research Facility Fund. The investment has built and equipped, as part of the Institute's infrastructure, a dedicat...

MU researcher placing eye implants in cats to help humans see

... by age four. To date, Narfstrom has performed surgeries in severely visually impaired or blind cats. During the surgery, Narfstrom makes two small cuts into the sclera, the outer wall of the eyeball. After removing the vitreous, which is the gelatinous fluid inside the back part of the eyeball, ...

No-scalpel vasectomies by skilled surgeons may speed recovery

The Duke team, which also includes Joanna Noble, an undergraduate student, and Matthew Fronheiser, a graduate student in Smith's laboratory, reported the findings in an issue of the journal Ultrasonic Imaging...

Circumcision: A proven strategy to prevent HIV

...urgery. According to Bailey, in 1.7 percent of the surgeries there were minor complications -- usually bleeding or a mild infection. There were no severe adverse events. Bailey cautions that circumcised men may feel they are protected from becoming HIV infected and may be more likely to engage in risky beha...

New fMRI technology making brain tumor surgery safer

...gy may make brain stimulation unnecessary for many surgeries in the future. The new BrainLAB equipment also enables physicians to integrate diffusion tensor imaging (DTI), which provides a map of critical white-matter tracts in the brain. “White-matter tracts,?said Dr. Leach, “are like the electrical conn...

Artificial cornea offers better results for infants, some blind patients

... these children, many of whom have endured several surgeries that have failed," said James Aquavella, M.D., the University of Rochester ophthalmologist who is pioneering the use of the implant and who operated on most of the children in the study. "These are children for whom, until now, there really has no...

Male circumcision reduces HIV risk, study stopped early

...cations from circumcision. However, 1.7 percent of surgeries resulted in mild complications, such as bleeding or infection. Bailey said that promoting circumcision in Africa must be done in conjunction with proper technical training and medical tools, equipment and supplies necessary to perform large number...

More kidney cancer is detected and treated early, yet death rate rises

..."What this shows us is that, despite more frequent surgeries for smaller kidney cancers, mortality among patients with kidney cancer has continued to increase," Hollingsworth says. "So even while detection and treatment are increasing and more tumors have become detectable, this study suggests a disconnect bec...

Many patients are left with a patchy, unfavorable appearance, including large scars and mismatched skin. The studies found the only way to surgically match facial skin texture, pliability and color is th...

Radiotherapy advance points way to noninvasive brain cancer treatment

...stretch survival limits are exceptionally invasive surgeries to remove the tumor and radiation treatment with the maximum tolerated dose - all of which leads to a painfully low quality of life. Because of this, researchers are racing to find better therapies to stop or slow GBM. In the Jan. 1, 2006 issue of t...
