Infection plays a larger role than lack of oxygen in premature infants with brain injury

Johns Hopkins researchers have dispelled the widespread belief among obstetricians that, in premature infants, brain injury results from a lack of oxygen, also called hypoxia, when, in fact, infection plays a larger role.

Sibling history is a better predictor of coronary heart disease than parental history or traditional risk factor scoring

Researchers at Johns Hopkins have found that sibling history -- whether or not a brother or sister had early heart disease -- is a better predictor of a person's likelihood of developing coronary heart disease than parental history or traditional risk factor scoring.

CT scans may be delivering as much radiation as a low-dose atomic bomb

Those full-body CT scans advertised at some health care centers may be delivering as much radiation as a low-dose atomic bomb, according to a new study. And that means people who get them could be raising their cancer risk, researchers from Columbia University report in the journal Radiology (Vol. 232, No. 3:735-738).

Research provides definitive evidence that radiation risk is associated with full-body CT scans

The risk of cancer mortality from a single full-body computed tomography (CT) scan is modest, but not negligible, and the risks resulting from elective annual scans are much higher, according to a study published in the September issue of the journal Radiology.

Surgeons remodel and replace man's jaw bone allowing him to eat first dinner in 9 years

“By the 4th week post-transplantation the patient enjoyed his first dinner in 9 years (bread and sausages); before reconstruction he had only been able to eat soft food and soup”.

Computed tomography may improve screening of latent atherosclerosis

Atherosclerosis is the progressive narrowing and hardening of the arteries over time, known to occur to some degree with aging; but other risk factors (such as high cholesterol, high blood pressure, smoking, diabetes and family history for atherosclerotic disease) that accelerate this process have been identified.

45% of specialists admit having made a recent medical error

Otolaryngologist Dr. David Roberson has first-hand experience with medical errors. He remembers one near-miss in a patient about to receive a cochlear implant – and says it typifies the kinds of mistakes he and his colleagues have turned up in a national survey.

Computer-aided detection (CAD) can help physicians locate and analyze images from computed tomography (CT) scans

The diagnostic imaging modality of computed tomography (CT) scan is very helpful in lung cancer assessment as it spots even small lung tumors that might go undetected in conventional chest X-ray and other tests.

Connection between air pollution and cardiovascular disease

Researchers at the University of Washington will direct the largest study of its kind to explore the connection between air pollution and the No. 1 cause of death in the United States: cardiovascular disease.

Increasing levels of growth hormone may be an effective treatment for HIV lipodystrophy

Increasing the body's production of growth hormone may be an effective treatment for HIV lipodystrophy, a syndrome involving the redistribution of fat and other metabolic changes in those receiving combination drug therapy for HIV infection.

Innovative type of brain scan can determine where blockages of blood to the brain lie

It's a no-brainer that the brain needs a constant supply of blood to keep it going. But some medical conditions can block or reduce that life-giving flow. Whether it's a stroke, a clogged artery or a brain tumor, any situation where blood can't get to the whole brain can lead to death or permanent disability.

American Heart reports on acute ischemic stroke and increased risk of bleeding in the brain

High blood levels of a cell-regulating protein in patients with acute ischemic stroke can identify those with an increased risk of bleeding in the brain, according to a report in today’s rapid access issue of Stroke: Journal of the American Heart Association.

Low back pain - does it need costly scan?

A major study has been conducted to evaluate the role of Magnetic Resonance Imaging (MRI) and Computed Tomography (CT) scans in the treatment of low back pain (LBP).

Radiologists use CT-Scans to inject gene therapy into tumors

Using CT-scan images to steer gene-therapy injections directly into the tumor offers a safe delivery method for treating patients with metastatic kidney cancer, report UCLA radiologists in the May issue of Radiology. Their findings could enhance the treatment of the disease, which resists traditional intravenous chemotherapy in 85 percent of cases.

CT colonography not presently a viable option for colorectal cancer screening

Findings of a new multicenter study by Cotton et al. published today in the Journal of the American Medical Association comparing standard colonoscopy with CT colonography for the detection of colorectal cancer reveal that this technology, in the form used most often in the United States, while of significant interest, is not presently a viable option for routine colorectal cancer screening.

Differing views on virtual colonoscopy accuracy

Demonstrating clearly that not all virtual colonoscopies are equal, the study, published in the December 2003 issue of The New England Journal of Medicine and the American Journal of Roentgenology, found the results found using the Viatronix V3D-Colon system for primary 3D reading to be equal to or better than optical colonoscopy results.

Lung tumor therapies improved by combining scanning technologies

Physicians targeting lung tumors for radiation therapy can substantially improve their aim by combining data from two scanning techniques, according to Washington University researchers at Siteman Cancer Center and Barnes-Jewish Hospital in St. Louis.

CT colonography lacks the sensitivity of conventional colonoscopy

A new study published in JAMA on CT colonography or 'virtual' colonoscopy using 2-D imaging finds that this test lacks the sensitivity and specificity of conventional colonoscopy for colorectal cancer screening. Study co-author and American College of Gastroenterology President Douglas K. Rex, M.D. is available for interviews.
