High-tech imaging software locates more accurately the abnormal electrical impulses that produce heart arrhythmias

Loyola University Health System is one of the first hospitals in the United States to employ new high-tech imaging software - in conjunction with a three-dimensional cardiac mapping and navigation system - to locate more accurately the abnormal electrical impulses that produce heart rhythm disturbances (arrhythmias). This technology represents a major breakthrough in treating complex arrhythmias.

Whole-body positron emission tomography/computed tomography scans may help physicians identify malignant cancerous tumors

A team of researchers at Johns Hopkins Medical Institutions in Baltimore, Md., reports that whole-body positron emission tomography/computed tomography (PET/CT) scans may help physicians identify new, unexpected malignant cancerous tumors in patients, according to an article in the May issue of the Society of Nuclear Medicine’s Journal of Nuclear Medicine.

Patients with metabolic syndrome and moderate calcium levels in the coronary arteries have greater chance of blocked arteries

Conditions such as abdominal obesity, high blood pressure, abnormal cholesterol levels and high blood sugar are problematic enough for people all on their own.

Vitamin E as part of diet may prevent Parkinson's

A new study by Canadian researchers at Royal Victoria Hospital in Quebec has shown that a moderate daily intake of vitamin E through foods appears to prevent the onset of Parkinson's disease.

Routinely reformatting computed tomography (CT) scans to view organs from several different directions may help radiologists improve diagnosis

"You can see things in one view that you might miss in another," said Craig Barnes, M.D., section head of pediatric radiology at Wake Forest Baptist's Brenner Children's Hospital. "It costs no more as relates to scan time or radiation exposure, and we believe it provides added value in diagnosis."

Women more vulnerable to chronic drinking than men are

A study in the May issue of Alcoholism: Clinical & Experimental Research addresses this gap in research, using computed tomography (CT) to examine brain atrophy in the brains of alcoholic men and women. The findings support and build upon a prior hypothesis that women develop alcohol-related brain damage more readily than men.

Breast CT may improve on mammography - more gentler, more accurate

A new breast screening technology that may be able to detect tumors earlier than mammography -- without the need for uncomfortable breast compression -- is being tested in patients at the University of California, Davis, Medical Center.

Swedish study suggests gay men's brains differ from heterosexual men's

Researchers in Sweden have found that a compound taken from male sweat stimulates the brains of gay men and straight women but not heterosexual men, which raises the possibility that homosexual brains are different.

$Soft tissue injuries can predict risk of facial fractures in trauma patients$

Soft tissue injuries can predict risk of facial fractures in trauma patients

Trauma patients with specific types of facial soft tissue injuries should have a CT (computed tomography) scan of the face as well as a standard head scan to determine the presence and severity of facial fractures, according to a study published in the May issue of the Journal of Oral and Maxillofacial Surgery.

Survey of ED doctors shows team-based stroke care, risk-reducing measures, needed to increase use of tPA

Forty percent of emergency physicians say they're unlikely to give stroke patients the only FDA-approved drug shown to improve their prognosis, even in an ideal setting, mostly because of the fear of causing brain bleeding.

Impact of acupuncture goes beyond the acknowledged placebo effect

Researchers at the University of Southampton and University College London have shown for the first time that the impact of acupuncture goes beyond the acknowledged placebo effect caused by the patient's own expectation of feeling benefit from the treatment.

Fusing physics with medicine to fight cancer

Everyone’s lives are touched by cancer - it is a disease that affects 1 in 3 of us throughout our lifetime. Future developments that lead to earlier diagnosis and more effective therapy lie in further successful collaboration between high energy physicists and the healthcare industry.

Discrimination leads to coronary artery calcification in African-American women

The more discrimination African-American women report, the more likely they are to have coronary artery calcification, a buildup of calcium in the vessels that is associated with atherosclerosis, according to a study presented at the American Heart Association's 45th Annual Conference on Cardiovascular Disease Epidemiology and Prevention.

Use of positron emission tomography may eliminate more strenuous drug development trials with animals

A number of articles explore the use of positron emission tomography (PET) and small animal imaging—nonsurgical techniques that open the door to understanding and treating human diseases—in the April issue of the Society of Nuclear Medicine’s Journal of Nuclear Medicine.

Using light under your skin

You have a tiny wound on your hand that doesn’t heal, a bad burn on your chest – or an injured retina. Your doctor cannot tell how serious the injuries are below the surface. He needs tissue samples. That means using a scalpel, which again equals pain, perhaps even a risk. Soon there may be hope for an improved and totally harmless method to peer under the surface of the skin: light.

Gene may boost schizophrenia risk

Clues about how a suspect version of a gene may slightly increase risk for schizophrenia are emerging from a brain imaging study by the National Institutes of Health's (NIH) National Institute of Mental Health (NIMH). The gene variant produced a telltale pattern of activity linked to production of a key brain messenger chemical.

“Virtual Colonoscopy” effective in finding most polyps but may miss small ones

A type of noninvasive “virtual colonoscopy” can diagnose medium to large polyps as well as traditional colorectal probes can, but it may miss some smaller yet potentially cancerous growths, according to a new review of studies.

Scientists reveal the shape of a protein that helps retroviruses break into cells

Retroviruses are among the trickier and more malicious disease agents, causing AIDS and cancers such as leukemia. The viruses manage to sneak into cells with the help of special protein assemblies scattered all over their surfaces. These retrovirus surface proteins cause the membrane envelope of the virus to fuse with the membrane of the cell, spilling virus RNA into the cell to wreak damage.

Smokers who receive abnormal results using computed tomography to screen for lung cancer are more likely to quit

According to a new study, smokers who receive multiple abnormal results using computed tomography (CT) to screen for lung cancer are more likely to quit, suggesting an opportunity for doctors to motivate smokers to quit smoking.

Osteoporosis drug reduces women's risk of mild cognitive impairment

A drug prescribed for the prevention of osteoporosis reduced women's risk of mild cognitive impairment by 33 percent in a worldwide clinical trial led by researchers at San Francisco VA Medical Center (SFVAMC).
