Simple assault and ground level fall do not require cervical spine CT

2012-05-04
(Press-News.org) Cervical spine CT examinations are unnecessary for emergency department (ED) patients who are a victim of "simple assault" or who have a "ground-level fall", unless the patient has a condition that predisposes the patient to spine fracture, a new study finds.

The study, conducted at Grady Memorial Hospital by researchers from the Department of Radiology and Imaging Sciences of the Emory University School of Medicine in Atlanta, found that out of 218 exams for simple assault, there were none that were positive, said Andrew Nicholson, MD, lead author of the study. In the series of 154 cervical spine CT scans that were obtained for ground-level fall, there was only one positive exam. This fracture was in a patient with ankylosing spondylitis, a condition that is known to increase the risk of fracture of the spine.

"The criteria that exist for cervical spine imaging can be vague in certain circumstances and lead to many patients receiving this exam who likely don't need it," said Dr. Nicholson. "At our level 1 trauma center in the past 12 months, there were 5,046 cervical spine CT examinations; in 2003, there were 2,091, an increase of 241%," he said.

"While this study looks at a relatively small subset of the CT exams ordered from the ED, we believe it can have a significant impact on radiation dose reduction at a population level," said Chad Holder, MD, senior author of the study. "These patients frequently have CT scans of the head and/or the face at the same time. The radiation dose to the lenses of the eyes, thyroid and lymph nodes from cervical spine CT is not insignificant; reducing unnecessary radiation exposure to these organs is important," he said. "Additionally, overutilization of high-cost imaging exams has contributed to the increase in healthcare expenditures. Efforts to contain these two aspects should be led by radiologists, who can be a driving force to reduce overutilization," said Dr. Nicholson.

The study will be presented on May 3 at the 2012 American Roentgen Ray Society Annual Meeting in Vancouver, Canada.

Surgical excision unnecessary in some patients with benign papillomas

2012-05-04
Imaging surveillance is an acceptable alternative to surgical excision in patients with benign papilloma, diagnosed at breast core biopsy without cell abnormalities, a new study shows. The study, conducted at the Breast Health Center of California Pacific Medical Center in San Francisco, included 119 papillomas diagnosed at core biopsy without abnormal cells. Imaging follow-up of a minimum of two years without surgical excision was performed on 66 lesions; no cancer was found in this group, said Jessica Leung, MD, FACR, lead author of the study. Surgical excision was ...

Study finds 'overmanagement' of benign breast disease

2012-05-04
Contrary to current guidelines, women with benign breast biopsies do not need follow-up at six months; they may not need close surveillance at all, a new study shows. The study, conducted at Moffitt Cancer Center in Tampa, FL, followed 388 patients for six, 12 and 24 months. No cancer was found in these patients at six and 12 months, said Shannon Reed, MD, one of the authors of the study. "Of the 197 follow-up examinations performed at 24 months, two women were positive for cancer in a different area than had been previously biopsied," said Dr. Reed. An annual ...

Increasing speed of Greenland glaciers gives new insight for rising sea level

Increasing speed of Greenland glaciers gives new insight for rising sea level
2012-05-04
Changes in the speed that ice travels in more than 200 outlet glaciers indicates that Greenland's contribution to rising sea level in the 21st century might be significantly less than the upper limits some scientists thought possible, a new study shows. "So far, on average we're seeing about a 30 percent speedup in 10 years," said Twila Moon, a University of Washington doctoral student in Earth and space sciences and lead author of a paper documenting the observations published May 4 in Science. The faster the glaciers move, the more ice and meltwater they release ...

Biologists turn back the clock to understand evolution of sex differences

Biologists turn back the clock to understand evolution of sex differences
2012-05-04
Sex differences account for some of the most of the spectacular traits in nature: the wild colours of male guppies, the plumage of peacocks, tusks on walruses and antlers on moose. Sexual conflict – the battle between males and females over mating – is thought to be a particularly potent force in driving the evolution traits that differ in males and females. However, the genetic processes responsible for producing such traits are not well understood, nor how they evolved from their simpler less elaborate ancestral forms. We tend to assume that each tiny step in evolution ...

Aged hematopoietic stem cells rejuvenated to be functionally younger

2012-05-04
CINCINNATI – Researchers have rejuvenated aged hematopoietic stem cells to be functionally younger, offering intriguing clues into how medicine might one day fend off some of the ailments of old age. Scientists at Cincinnati Children's Hospital Medical Center and the Ulm University Medicine in Germany report their findings online May 3 in the journal Cell Stem Cell. The paper brings new perspective to what has been a life science controversy – countering what used to be broad consensus that the aging of hematopoietic stem cells (HSCs) was locked in by nature and not reversible ...

The American College of Rheumatology issues guidelines for management of lupus nephritis

2012-05-04
The American College of Rheumatology (ACR) has issued newly created guidelines for the screening, treatment, and management of lupus nephritis—a severe manifestation of systemic lupus erythematosus (SLE) where the disease attacks the kidneys. Previously, only general guidelines for SLE existed for clinicians. The guidelines, available today in Arthritis Care & Research, are specific to lupus nephritis and include methods for identifying renal disease, newer therapies, and treatment of pregnant SLE patients with kidney involvement. The ACR estimates that up to 322,000 ...

Naturally blond hair in Solomon Islanders rooted in native gene, Stanford study finds

2012-05-04
STANFORD, Calif. — The common occurrence of blond hair among the dark-skinned indigenous people of the Solomon Islands is due to a homegrown genetic variant distinct from the gene that leads to blond hair in Europeans, according to a new study from the Stanford University School of Medicine. "This is one of the most beautiful examples to date of the mapping of a simple genetic trait in humans," said David Reich, PhD, a professor of genetics at Harvard University, who was not involved in the study. The study identifying the gene responsible for blond hair in the Solomon ...

Double duty: Versatile immune cells play dual roles in human skin

2012-05-04
A new study helps to resolve an ongoing controversy about whether Langerhans cells (LCs) in human skin function to suppress the immune response and promote tolerance to normal human skin and its "friendly" microbial flora or mobilize a lethal attack against harmful foreign invaders. The research, published online May 3rd in the journal Immunity by Cell Press, reveals that, depending on the situation, these versatile immune cells can perform either function. Adult human skin contains billions of resident immune cells called T cells that provide protection from invading ...

Pleasure eating triggers body's reward system and may stimulate overeating

2012-05-04
When eating is motivated by pleasure, rather than hunger, endogenous rewarding chemical signals are activated which can lead to overeating, according to a recent study accepted for publication in The Endocrine Society's Journal of Clinical Endocrinology & Metabolism (JCEM). The phenomenon ultimately affects body mass and may be a factor in the continuing rise of obesity. "'Hedonic hunger' refers to the desire to eat for pleasure, and to enjoy the taste, rather than to restore the body's energy needs,"says Palmiero Monteleone, MD, of the University of Naples SUN in Italy ...
