27 percent of children wait too long for surgery

2011-05-03
(Press-News.org) News Release Embargoed until Monday, May 2, 2011, noon EDT
Please credit CMAJ, not the Canadian Medical Association. CMAJ is an independent medical journal; views expressed here do not necessarily reflect those of its owner, the CMA.

Twenty-seven percent of children in Canada awaiting surgery at pediatric hospitals received the procedures past the target date, found an article in CMAJ (Canadian Medical Association Journal) (pre-embargo link only) http://www.cmaj.ca/embargo/cmaj101530.pdf.

Prolonged wait times are a pressing issue in health care systems and Canadian governments at the federal, provincial and territorial levels have made reducing wait times a priority. However, some procedures may need to be performed sooner than by the established six-month target date.

The study, by researchers from the Hospital for Sick Children (SickKids) and the Canadian Paediatric Surgical Wait Times Project, was based on 64 012 surgeries at Canada's pediatric academic health centres. Dentistry (45%), ophthalmology (43%) and plastic surgery (35%) had the highest percentage of delayed surgeries followed by cancer, neurosurgery, and cardiac surgery.

"Despite receipt of surgery within six months of the decision to treat for 90% of patients, clinically derived targets found that 27% of children waited too long for their specific condition," writes Dr. James G. Wright, The Hospital for Sick Children, Department of Surgery, with coauthors.

Delays in surgery can affect children's physical and cognitive development. For example, delaying surgery to correct strabismus risks a child's chances of having normal vision and can affect quality of life.

"We believe this national collaborative project shows the feasibility and potential benefits of setting nationals standards for surgical wait times. Such accountability can result in measurably improved access in the delivery of national publicly funded health care," they conclude.

In a related research article http://www.cmaj.ca/embargo/cmaj101511.pdf, researchers found that waiting for surgery beyond wait time targets can affect the outcomes and risks associated with surgery. The authors found that wait times longer than three months for adolescents with scoliosis increase the likelihood of complications and additional surgeries. Surgery to correct idiopathic scoliosis, an abnormal curvature of the spine that is potentially progressive during adolescence, is the most common reason for elective pediatric orthopedic surgery.

"The highest risks of adverse events due to prolonged wait times occurred in patients who were skeletally immature and had larger curvatures of the spine," writes author Dr. Henry Ahn, St. Michael's Hospital, Toronto, with coauthors.

They conclude that a three-month wait time, based on empirical analysis rather than on conventional methods such as expert opinion, helps minimize risk. "A maximal acceptable wait time that leads to a reduction in the progression of curvature also has the potential to reduce the strain on healthcare resources by decreasing the need for additional surgery."

No nuts for 'Nutcracker Man'

No nuts for Nutcracker Man
2011-05-03
SALT LAKE CITY, May 2, 2011 –- For decades, a 2.3 million- to 1.2 million-year-old human relative named Paranthropus boisei has been nicknamed Nutcracker Man because of his big, flat molar teeth and thick, powerful jaw. But a definitive new University of Utah study shows that Nutcracker Man didn't eat nuts, but instead chewed grasses and possibly sedges –- a discovery that upsets conventional wisdom about early humanity's diet. "It most likely was eating grass, and most definitely was not cracking nuts," says geochemist Thure Cerling, lead author of the study published ...

No uptake of grant relating to ban on blood donations by gay and bisexual men

2011-05-03
Canadian researchers may be biased since a half-million dollar research grant to possibly change the ban on gay and bisexual men donating blood has not been accessed, states a Salon article in CMAJ (Canadian Medical Association Journal) (pre-embargo link only) http://www.cmaj.ca/embargo/cmaj110262.pdf. "As to why researchers did not proceed in their normal fashion, which is to fiercely compete for any relevant funding opportunity, remains unknown," write Jason Behrmann and Vardit Ravitsky, University of Montreal. "However, a clue may lie in the fact that this grant aims ...

New evidence details spread of amphibian-killing disease from Mexico through Central America

2011-05-03
Using museum specimens from Mexico, Guatemala and Costa Rica, a team of researchers from San Francisco State University and University of California at Berkeley has documented evidence of a Batrachochytrium dendrobatidis (Bd) epidemic wave that wiped out native amphibians, according to research to be published on May 3 by the Proceedings of the National Academy of Sciences. (PNAS). More than 40 percent of all amphibian species are currently in decline, with many species having already disappeared, even in protected areas. The suspected culprit has been the emergence ...

The winners of mass extinction: With predators gone, prey thrives

The winners of mass extinction: With predators gone, prey thrives
2011-05-03
In modern ecology, the removal or addition of a predator to an ecosystem can produce dramatic changes in the population of prey species. For the first time, scientists have observed the same dynamics in the fossil record, thanks to a mass extinction that decimated ocean life 360 million years ago. What was bad for fish was good for the fish's food, according to a paper published today in Proceedings of the National Academy of Sciences. Researchers from the University of Chicago, West Virginia University, and The Ohio State University find that the mass extinction known ...

Catheterization recommended for treating pediatric heart conditions

2011-05-03
Doctors should consider using catheterization as a treatment tool in addition to its established role in diagnosing children with heart defects, according to a new American Heart Association scientific statement. A catheter is a thin flexible tube inserted into a blood vessel and used in procedures such as angiography, in which physicians use the catheter to inject dye into the arteries near the heart to illuminate the vessels via X-ray technology. It can also open a valve, enlarge a narrow blood vessel, close a hole in the heart or close off a blood vessel. The statement, ...

Public confused about ingredients in pain relievers

2011-05-03
CHICAGO --- People take billions of doses of over-the-counter pain relievers like Tylenol every year, but many do not pay attention to the active ingredients they contain, such as acetaminophen, according to a new Northwestern Medicine study. That lack of knowledge about popular pain relievers plus particular ignorance of acetaminophen's presence in more than 600 over-the-counter and prescription medicines could be a key reason acetaminophen overdose has become the leading cause of acute liver failure in the U.S. The study reported only 31 percent of participants knew ...

Skin sensitivity to food allergens explained

2011-05-03
Atopic dermatitis is a form of eczema that is caused by an inappropriate inflammatory response in the skin. Many children with atopic dermatitis also have food allergies, and skin contact with food allergens can make their atopic dermatitis worse. It is unclear why this occurs, but it has been suggested that immune cells known as T cells that are sensitized by exposure to food allergens in the gut are responsible. Raif Geha and colleagues, at Harvard Medical School, Boston, have now generated data in a mouse model of food allergen–induced atopic dermatitis that support ...

Cells derived from different stem cells: Same or different?

2011-05-03
Stem cells are considered by many to be promising candidate sources of cells for therapies to regenerate and repair diseased tissues. There are two types of stem cell considered in this context: embryonic stem (ES) cells, which are derived from early embryos; and induced pluripotent stem (iPS) cells, which are derived by reprogramming cells of the body such that they have the ability to generate any cell type. Recent data indicate that ES and iPS cells are molecularly different, raising the possibility that cells derived from these two sources could be distinct. A team ...
