Study identifies day-of-surgery crisis

A study from Sydney University's Centre for Health Services based at Westmead Hospital, has shown that more than one in 10 operations over a six month period were cancelled at the last minute.

Risks are too high for pregnant women during the summer

Most pregnant women don't drink, speed, or behave recklessly; yet many will end up in trauma rooms across Canada this summer.

New study finds many concerns with clinical trials

A new study led by OHRI Scientist and University of Ottawa Professor, Dr. Dean Fergusson, has looked at current practices in justifying the conduct of clinical trials and found many concerns. For starters, the report notes, some researchers don't even look at existing evidence, repeating trials that have already been conducted and scientifically validated.

Keyhole surgery can be safely used for the removal of tumours from the colon

The safety and short-term benefits of keyhole surgery for colon cancer have been debatable. Minimally invasive surgery for cancer reduces surgical trauma but there has been concern that it could lead to tumour recurrence.

Children who are prone to frequent ear infections may have a high number of potentially infectious bacteria

...and a relatively low number of protective bacteria in their noses, according to a study in the June issue of Archives of Otolaryngology - Head & Neck Surgery, one of the JAMA/Archives journals.

Gastroesophageal reflux disease (GERD) may be associated with more cases of cancers than previously thought

The relationship of GERD and adenocarcinoma (type of cancer) of the esophagus is clear for tumors located along the tubular portion of the esophagus, regardless of whether Barrett mucosa (a condition where the cellular lining of the esophagus has been changed, often caused by gastric reflux) is found.

Researchers use novel cocktail of cells to coax muscle tissue to develop its own vascular network

For years, a major obstacle has dashed the hopes of creating "replacement parts" for the human body: the lack of an internal, nourishing blood system in engineered tissues. Without it, thicker tissues can't thrive, which has confined tissue engineering's practical application to thin skin, which can recruit blood vessels from underlying tissue.

Study finds better long-term outcomes when surgeons place a bypass graft to all the territories of the heart that have significantly blocked arteries

Pointing out that not all coronary artery bypass operations are performed the same way or have equivalent outcomes, cardiothoracic surgeons at Cedars-Sinai Medical Center have found that patients who have blockages of multiple coronary arteries and undergo "complete revascularization" - grafting of arteries to restore blood flow to all affected territories of the heart - have consistently better long-term survival rates than those who have "incomplete revascularization."

Faulty defibrillators may mean surgery for thousands of cardiac patients

Surgery to replace possibly faulty implanted cardiac defibrillators may now be on the cards for thousands of cardiac patients.

Fine tuning drug levels in neuroblastoma patients is effective

Monitoring and fine tuning the levels of the cancer drug topotecan in children with neuroblastoma holds promise for maximizing the drug's effectiveness while reducing its toxicity, according to investigators at St. Jude Children's Research Hospital.

High-volume medical centers better at treating cancer

Patients with certain complex cancers fare better under the care of doctors and hospitals that do the most of that kind of surgery, a new review of studies finds.

MRI measurement of breast tumor volume predicts whether a patient's cancer will return

The study, performed at the University of California-San Francisco, of 58 breast cancer patients found that the best way to predict a patient's recurrence-free survival is to review the initial MR examination (before the patient has chemotherapy) and the final MR examination (after chemotherapy has been completed).

U.S. scientists have successfully engineered blood vessels from human vascular cells in the lab

Tissue engineering has made considerable progress in the past decade, but advances have stopped short of clinical application for most tissues. For elderly patients tissue-engineered arteries could provide grafts for bypass surgery.

Aortic disease difficult to diagnose

Aortic disease kills nearly 15,000 people in the United States each year, but the rarity and complexity of this deadly disorder make accurately diagnosing it difficult for doctors in the health-care trenches, University of Florida researchers have found.

Diabetes patients may benefit most from minor surgery plus antibiotics

A small sore on a toe may not seem like a major medical threat. But for the millions of people who have diabetes and other conditions, it can be the first step on a road that leads to the amputation of a foot -- or even a leg.

FDA approves Xeloda (capecitabine) oral chemotherapy

Roche announced today that the U.S. Food and Drug Administration (FDA) has approved Xeloda (capecitabine) -- an innovative oral chemotherapy -- for the adjuvant (post-surgery) treatment of patients with Dukes' C colon cancer.

Brain surgery for epilepsy means patients still free of fits 30 years later

A study has shown that thirty years after undergoing temporal lobectomy for epilepsy, half of patients are still free from seizures.

Arteries bio-engineered from elderly cells

Researchers from Duke University's Medical Center and Pratt School of Engineering have demonstrated that they can grow new human blood vessels from cells taken from patients who especially need such assistance – older adults with cardiovascular disease.
