Ultrasound Elastography

1 Technique Identifies Patients Who Need Biopsy

Ultrasound elastography, a new technique that helps distinguish malignant from benign breast lesions may result in fewer unnecessary biopsies, finds a new study. Ultrasound elastography works by indicating tissue softness, says lead researcher Dr. Hiroko Satake, Nagoya University School of Medicine, who explains that malignant tumors are harder than benign ones. In an analysis of 115 breast masses that were recommended for biopsy, ultrasound elastography was 79% accurate in identifying cancer. “By accurately identifying benign tumors with imaging, we may be able to avoid sending patients for unnecessary biopsies," says Dr. Satake who notes that utrasound elastography should be used as an adjunct to standard sonography and dynamic contrast-enhanced MRI.

When Diagnosis Certain

2 Antibiotics Good for Middle Ear Infection

Despite some guidelines that say otherwise, antibiotics may still be good for treating middle ear infection when the diagnosis is certain, find two recent studies. The research, reported in the New England Journal of Medicine, shows that symptoms may disappear sooner when an antibiotic like amoxicillin-clavulanate is used. According to MSNBC, the new results contradict the latest recommendation by the American Academy of Family Physicians to use a "watchful-waiting approach" for most cases. Dr. Jerome O. Klein of the Boston University School of Medicine believes that the new study findings offer "the best data yet" on whether antibiotics are a good treatment for middle ear infections. He says the answer is "yes."

Is Your Good HDL Really Good?

3 Good Cholesterol: Not All HDL Equal

Some "good" HDL cholesterol is better than other HDL at getting rid of "bad" cholesterol, or LDL. New research suggests that heart disease risk may be better determined by measuring the ability of HDL to remove plaque from arteries. A simple measure of HDL may not be enough. Dr. Daniel J. Rader of the University of Pennsylvania School of Medicine thinks that a compound or protein in some kinds of HDL is better at eliminating bad cholesterol than other kinds of HDL. Samples of HDL cholesterol taken from people with coronary artery disease didn't remove cholesterol from cells as well as HDL cholesterol from healthy people studied. The research, published in New England Journal of Medicine, may help explain why some people with high levels of HDL still have high heart disease risk.

4 New Guidelines for Preventing Falls in Elderly

Fall prevention efforts for the elderly should include an exercise component, say the American Geriatrics Society and the British Geriatric Society in their first update in guidelines for fall prevention for the elderly since 2001. "Given their frequency and consequences, falls are as serious a health problem for older persons as heart attacks and strokes," says one of the panel chairs, Dr. Mary Tinetti of Yale University School of Medicine. The updated guidelines suggest exercises like Tai Chi or physical therapy for balance, gait and strength training. Other recommendations include medication reduction (specifically sleeping meds and antidepressants) and focusing on raising low blood pressure. A summary of the new guidelines is published in Journal of the American Geriatrics Society.

Stopping, Not Masking Ringing

5 New Treatment Hope for Tinnitus

There's new hope for people who suffer from tinnitus, a ringing noise in the ears that affects 40 percent of military veterans and 10 percent of senior citizens, reports MSNBC. Unlike previous treatments, this new treatment aims to eliminate, not mask, the noise of tinnitus. Human trials of the new treatment will start in Europe this year. The treatment, which has been successful in rats, involves stimulating the vagus nerve in the neck with a device that simultaneously plays different sounds for several weeks. MicroTransponder is manufacturing the device for the human trial. The University of Texas at Dallas published their tinnitus research involving the device in the journal Nature.

Unusual Partners

6 Frog Takes Ride on Snake in Australian Flood

A frog hitched a ride on the back of a snake searching for dry land during flooding in Queensland, Australia. TreeHugger published the amazing image of the frog riding snake-back. The photo was taken by computer technician Armin Gerlach, who was inspecting flood damage as the unusual duo sped by. Gerlach was quoted in Australia's Ninemsn as saying "I felt amazement, I just couldn't believe it."

High Public Health Burden

7 More Than 8 Percent of Americans Have Asthma

According to the most current statistics released by the Centers for Disease Control and Prevention, asthma prevalence in the United States was 8.2 percent in 2009. Rates are highest among women, children, individuals of non-Hispanic black and Puerto Rican race or ethnicity, those with family income below the poverty level, and individuals living in the Northeast and Midwest regions. The condition is associated with substantial loss of work and school days as well as increases in emergency department visits and hospitalizations. A preliminary figure estimates that there were almost 3,400 deaths due to asthma in 2008. The authors write that despite the conditions’ high burden, the treatment of asthma remains below the targets set by the Healthy People 2010 initiative.

Kids and Teens Beware

8 Bottle Rockets Linked to Significant Eye Injury

Bottle rockets, a type of consumer firework, have been associated with significant eye injuries among children and adolescents, according to a study conducted at Vanderbilt University School of Medicine and published in the January 10th issue of the Archives of Ophthalmology. Investigators found significant ocular injuries, including corneal epithelial defect, hyphema, traumatic iritis, cataract, and vitreous hemorrhage related to the use of bottle rockets. Primary intervention, including surgery, was required in the majority of those studied. Bottle rockets are illegal in several states in the US, but are cheap and easy to obtain. The rockets are a hazard because of their ability to fly in many directions other than just vertically.

Clowning Around After IVF

9 Laughter Increases Success of IVF

Thirty-six percent of women who saw a “medical clown” for 15 minutes after in vitro fertilization (IVF) became pregnant compared to only 20 percent who did not according to a new study conducted in Israel. Lead researcher Dr. Shevach Friedler had read about laughter can alter the physiology and fight stress, he developed the study. The clown performed a specific routine and visited the fertility clinic from time to time for a year. More studies will need to be done to demonstrate if other techniques that reduce stress would also work. Most “clown care” is used in pediatric hospitals throughout the U.S., Canada, Europe and Australia. For those interested in specializing in “medical clowning,” a degree in the field can be obtained at the University of Haifa in Israel.

One Mechanism, Two Conditions

10 Dementia in Alzheimer's and Down Syndrome Linked

A new study demonstrates that overproduction of a protein called Calcineurin 1 (RCAN1) leads to a series of events at the molecular level that kill brain cells in the hippocampus and cortex in individuals with Down Syndrome DS) and Alzheimer’s. Dementia due to Alzheimer’s is usually seen in people over 60 years old, while individuals with DS can develop the condition that leads with memory loss and cognitive impairments in their 30s. People with DS have an extra gene that produces the protein, and it is the main reason they have a shorter lifespan. Why some with Alzheimer’s have the elevated RCAN1 levels is not known at this point. The goal of identifying the protein responsible for dementia is to develop treatments that inhibit its production so brain cells are not destroyed.
