Lauran Neergaard, AP Having a bad reaction to penicillin as a child doesn't guarantee you're still allergic decades later. And if the oncologist says you have to switch chemotherapies because of an allergic reaction, well, maybe not. More medical centers are recommending a lesser known choice: Drug desensitization, a carefully controlled method of helping patients temporarily tolerate medications that their bodies once rejected.
Chronic stress has recently been implicated as a factor that may accelerate the growth of tumors. However, the mechanisms underlying this effect have not been determined, offers Anil Sood and colleagues at the University of Texas MD Anderson Cancer Center, Houston. They have generated data using human ovarian cancer cell lines and tumor specimens that indicate that stress hormones, especially norepinephrine and epinephrine, can contribute to tumor progression in patients with ovarian cancer.
Replacing failing artificial animal-based heart valves by implanting mechanical valves inside them is an effective option for high-risk patients, according to research reported in Circulation: Journal Of The American Heart Association. In the study, physicians describe how 24 high-risk patients, whose previous implants failed, received transcatheter valve-in-valve implantation – where a new artificial valve is seated within a previously implanted valve made of pig or cow tissue.
A research team led by Mayo Clinic has found a national trend toward younger, more diverse patients having total knee replacement surgery. The findings were presented at the 2010 annual meeting of the American Academy of Orthopaedic Surgeons in New Orleans. Additional audio and video resources including excerpts from an interview with Dr.
On the heels of a sudden outpouring of support, it looks as if a Cambodian girl will have a chance at risky, but potentially life-extending surgery. A week after the founder of a local non-profit worried that his fledgling group would not be able to raise the money needed to provide open-heart surgery for 3-year-old Socheat Nha, the group's fortunes have turned.
A new report from critical care experts at Johns Hopkins shows the benefits of reducing the use of prescription sedatives by half so that mild exercise programs can be introduced to critically ill patients in the ICU. Curtailing use of the drowsiness-inducing medications not only allows patients to exercise, which is known to reduce muscle weakness linked to long periods of bed rest, but also reduces bouts of delirium and hallucinations and speeds up ICU recovery times by as much as two to three days, the paper concludes.
Being obese may increase the cost of surgery for men with prostate cancer, a new study suggests. Researchers found that among 629 prostate cancer patients at their center who had a radical prostatectomy, obese men generally incurred greater costs. The difference came from higher costs for anesthesia and other services in the OR.

Researchers at Wake Forest University in Winston-Salem, NC, have developed a device that can spray skin cells directly onto burn victims to protect and heal wounds as an alternative to skin grafts April 12, 2010 Inspired by a standard office inkjet printer, researchers at Wake Forest University in Winston-Salem, NC, have developed a device that can spray skin cells directly onto burn victims, quickly protecting and healing their wounds as an alternative to skin grafts, Reuters reported last week.

A Message from Dr. David Blumenthal, National Coordinator for Health Information Technology: “I know that health care providers are concerned about implementing new health information technology and finding professionals who can operate and maintain such systems. I know many clinicians are unsure how they will develop or strengthen their skill set to incorporate using health IT efficiently and effectively without jeopardizing their communication with patients during a clinical visit.
Using adult stem cells, researchers have created functional blood vessels that could one day replace synthetic grafts often required in various vascular bypass surgeries, according to research presented at the American Heart Association's Arteriosclerosis, Thrombosis and Vascular Biology Annual Conference 2010.
Nicotine withdrawal can cause dangerous agitation in intensive care patients. Researchers writing in BioMed Central's open access journal Critical Care found that, compared to non-smokers, agitated smokers were more likely to accidentally remove tubes and catheters, require supplemental sedative, analgesic or anti-psychotic medications, or need physical restraints.
A Los Angeles surgeon has been ordered to pay a Maryland patient and his wife $800,600 in a malpractice judgement.
