MCG is one of 20 centers internationally and the only place in Georgia studying new technology developed by Z-Tech Inc., to compare traditional mammograms with impedence scanning, a technique based on evidence that electrical current passes through cancerous tissue differently than through normal tissue.
This phase of the study will focus on women age 40-50. Older women have less dense breast tissue so cancer is easier to find, says Dr. James Craft, MCG radiologist and principal investigator on the study. Mammograms, also performed in the study, are more accurate in this population, so this phase will be a tougher test of the new technology, he says. The first phase of the study, which began in 2005, was open to women of all ages.

“Normal breast tissue is very dense, especially in younger women, and can hide tumors,” Dr. Craft says. “While we’ve known for a while that water flows more freely through cancerous cells, we also know that electrical current flows easier through cancerous and tumor tissue.”

The Z-Tech scan works by placing a flower-shaped grouping of electrodes over each breast and sending a small, painless amount of electricity through them. Unlike traditional mammography, the scan does not involve breast compression or radiation.

“It’s like doing an EKG of the breast,” Dr. Craft says.

A computer immediately calculates and presents a report based on the electrical signature of the breast tissue. Rather than waiting on breast image from a traditional mammogram, the computer immediately notes whether the scan is positive or negative for cancer.

However, for study purposes, neither Dr. Craft nor the patient will know the results. Patients must undergo a mammogram within 90 days, which Dr. Craft interprets. Z-Tech compares those results to the electrical study.

The hope is that the new test – called HEDA for Homologous Electrical Difference Analysis – will provide an alternative to mammograms. While Dr. Craft believes that having this test should help find more cancers, he doesn’t think it will replace traditional mammography.

“This method doesn’t use radiation, is portable and there is no pain associated with the squeezing that mammograms require,” he says. “I can see it being used as an additional test. I don’t think it will replace mammography, but it could increase our chances of catching breast cancer.”

The second phase of the Z-Tech trial is open to women age 40-50 having routine mammograms as well as those who have a suspicious lump scheduled for biopsy.

Malignant Mesothelioma

Jul 21, 2008 Author: admin | Filed under: Google Health, Health News, Mesothelioma News

HISTORICAL PERSPECTIVE
The existence of malignant mesothelioma as a primary tumor of
the pleura, peritoneum, pericardium, and other organs has long been
controversial. As early as 1767, however, Joseph Lieutaud is credited
with describing two cases of probable mesothelioma in a study of
3,000 autopsies, and E. Wagner recognized the disease as a pathologic
entity in 1870.238,239,298 Klemperer and Rabin described in detail the
histologic features of benign (localized) and malignant (diffuse)
mesotheliomas in 1931.143 A case record of malignant pleural
mesothelioma discussed in 1947 led neither to the recognition of the
diagnosis nor to the suspicion of asbestos as a causative factor, even
though the introductory sentence included the term asbestos worker,
and later the patient’s work was described as “cutting asbestos insulating
board.”48 This controversy lasted until 1960, when the major etiologic
factor (i.e., asbestos) was established in a seminal report by J. C.
Wagner and colleagues in 32 of 33 cases of mesothelioma, largely by
environmental exposure in the “Asbestos Hills” of Cape Province in
South Africa.295 Such a singular relationship, confirmed in many other
countries including the United States, established the disease as a distinct
nosologic entity.236

INCIDENCE AND EPIDEMIOLOGY
Mesothelioma has been such a rare disease, or one recognized so
infrequently, that it has not been coded as a separate cause of death and
has been seriously underestimated in mortality statistics.71,236 The
age-adjusted incidence of pleural and peritoneal mesothelioma in the
United States has been estimated at 14.2 per million per year, with
almost a three-fold increase for pleural mesothelioma in Caucasian
males between 1973 and 1984.71 The male-female ratio is about 4:1,
and 80% arise from the pleura.71 Cases tend to be clustered in areas of
asbestos product plants and shipbuilding facilities.94 Similar trends
have been reported in other industrialized countries, such as England.
104 In autopsy studies, the frequency of malignant mesothelioma
varies from 0.02 to 0.7%, with a rate of 0.2% in the largest series.127
In most hospital series, the pleura is more often involved than the
peritoneum, with a predominance of the right side over the left
(60:40).127 In some epidemiologic studies monitoring cohorts of
asbestos workers, however, the peritoneal form is more common than
the pleural.238
The mean age of patients is approximately 60 years,16,93,214,305 but
the disease can occur at any age, including in childhood.116 In a review
of 80 children with a diagnosis of malignant mesothelioma, the mean
age was 9.7 years, and 59% were male. Only 2 children were noted to
have a history of possible asbestos exposure, 1 had received radiotherapy
for Wilms’ tumor, and 1 had been exposed to isoniazid in utero.102

Summer Exercise Safety

Jul 9, 2008 Author: admin | Filed under: Beauty & Style, Diet & Fitness, Google Health, Health News

Hey everyone!

I’m in NYC, working from a girfriend’s office and generally just acting like I own this town. Last night we ate at this cute spot called The Grey Dog’s Cafe where I washed down a chicken and avocado salad with a pint of sangria and then splurged on Pinkberry ($-wise, I mean; a medium with mangoes and strawberries costs more than a martini. OK, half a martini.) Tomorrow I’ll be appearing on on the Today Show (link to come), spouting off about everything you need to exercise safely outside in the summer…not including obvious gimmes like sunblock and bug spray.

Here’s the scoop:

Drink up!
HydraCoach hydration monitor calculates, monitors and provides instant feedback on fluid consumption. You just punch in your weight and activity for the day and it spits out a personal hydration goal. Then, it coaches you to drink more (or less, for you overachievers out there) as the day goes on! It’s like a mini Jillian Michaels, in water bottle form. i need this considering the majority of water I drink during the day comes from inadvertently swallowing some while brushing my teeth or showering.

Sigg water bottles are reusable so you’re not leaving a mini-carbon footprint every day, plus they have a water-based, non-toxic coating baked into the interior – nothing leaching into your H20. (Perhaps you’ve heard of BPA, or bisphenol-A, a lovely toxin that seeps out of plastic bottles and mimics estrogen in the body? Yucksters.)

Don’t be a victim
AirDrive earphones let you jam to G. Stefani but also allow you to hear ambient noise, like traffic or someone approaching you from behind.

Tip: According to the Department of Justice, nearly one quarter of violent crimes occur during leisure activities away from home…like running.

Fight back
The New Balance/Via pedometer has - get this - a panic button. That is so Jodie Foster! Keep track of your steps and know that should, God forbid anything happen, you can pull up a lever and sound a 120 decibel screeching alarm (for comparison, a power saw is 110 decibels…your baby crying for two hours straight is about 200 decibels.). Plus, you can keep track of your calories! (sarcasm, ok?)

Tip: There are now some studies suggesting that walking 10,000 steps a day is the best. Try starting with 2500/day as a goal.

Keep track of your heart rate
NuMetrex sportsbras and tanks incorporate a heart rate monitor into the clothing itself. I haven’t been so psyched about a techie clothing product since Hypercolor shirts. Not only can you ensure you’re in your target heart rate zone without taking your pulse, but you can avoid overdoing it - crucial in heat and humidity.

Tip: According to the American Heart Association, your maximum heart rate is about 220 minus your age. You want to staying within 50 to 85 percent of your maximum heart rate–this range is called your target heart rate. For a 30-year-old woman, 95-162 beats per minute is your target heart rate.

Stay cool
Champion’s O2Cool line is made with two moisture-wicking layers and is eco-chic (made with fibers) Besides wicking sweat away, mesh panels and mesh-vented bras add cool ventilation

Insider tip: This stuff is on sale now!

Be seen at night
For you super hardcore nighttime exercisers out there, illumiNITE clothing gives ya head-to-toe reflectivity. A special material acts like a bazillion little mirrors working together to reflect light back to its originating source, meaning drivers see your entire silhouette.

If you wanna be seen but don’t want to light up like a Christmas tree, make sure your gear has reflective stripes or logos. Try Lucy, maker of all things gorgeous and beautiful. I especially like their Interval Skirt, which has a cute reflective design on the front left hip and back right hem. Plus, their website touts the skirt’s contoured waistband as being “anti-muffintop” which makes me giggle.

Tip: The largest number of pedestrian accidents and fatalities occur during the morning and evening hours as the sun is rising or falling. People are almost twice as likely to get in a car accident the Monday after Daylight Savings Time, as we’re not used to changes in sunlight.

Hope you can catch the show tomorrow - I’ll be on sometime in the 9 o’clock hour. When I smile, it means I’m think of you!

Cholesterol Drugs for Kids

Jul 9, 2008 Author: admin | Filed under: Google Health, Health News, Science News

The nation’s pediatricians are recommending wider cholesterol screening for children and more aggressive use of cholesterol-lowering drugs starting as early as the age of 8 in hopes of preventing adult heart problems.

The new guidelines were to be issued by the American Academy of Pediatrics on Monday. The push to aggressively screen and medicate for high cholesterol in children is certain to create controversy amid a continuing debate about the use of prescription drugs in children as well as the best approaches to ward off heart disease in adults.

But proponents say there is growing evidence that the first signs of heart disease show up in childhood, and with 30 percent of the nation’s children overweight or obese, many doctors fear that a rash of early heart attacks and diabetes is on the horizon as these children grow up.

Previously, the academy had said cholesterol drugs should be considered in children older than 10 if they fail to lose weight after a 6- to 12-month effort. The academy estimated that under the current guidelines, 30 percent to 60 percent of children with high cholesterol were being missed. And for some children, cholesterol-lowering drugs, called statins, may be their best hope of lowering their risk of early heart attack, proponents said.

“We are in an epidemic,” said Dr. Jatinder Bhatia, a member of the academy’s nutrition committee who is a professor and chief of neonatology at the Medical College of Georgia in Augusta. “The risk of giving statins at a lower age is less than the benefit you’re going to get out of it.”

Dr. Bhatia said that although there was not “a whole lot” of data on pediatric use of cholesterol-lowering drugs, recent research showed that the drugs were generally safe for children.

Surprisingly, the paper published in the medical journal Pediatrics that explains the new guidelines notes that among adolescents, average total cholesterol levels as well as LDL and HDL cholesterol have remained stable, while triglyceride levels have dropped, based on data collected from 1988 to 2000.

It is not clear how many children would be affected by the new guidelines. The recommendations call for cholesterol screening of children and adolescents, starting as early as the age of 2 and no later than the age of 10, if they come from families with a history of high cholesterol or heart attacks before 55 for men and 65 for women.

Screening is also recommended for children when family history is unknown, or if they have other risk factors, like being at or above the 85th percentile for weight, or have diabetes.

If the child’s cholesterol level is normal, retesting is suggested in three to five years. Although lifestyle changes are still recommended as the first course of action, drug treatment should be considered for children 8 years and older who have bad cholesterol of 190 milligrams per deciliter as when cholesterol reaches 160 in children who also have a family history of early heart disease or two additional risk factors, the new recommendations say. Children with diabetes may be considered for drug treatment when cholesterol reaches 130 mg/dL.

The guidelines give no guidance on how long a child should stay on drug treatment. But they do say the first goal should be to lower bad cholesterol levels to less than 160 milligrams or possibly as low as 110 milligrams in children with a strong family history of heart disease or other risk factors like obesity.

Because statins have been around since only the mid-1980s, there is no evidence to show whether giving statins to a child will lower the risk for heart attack in middle age.

The academy also now recommends giving children low-fat milk after 12 months if a doctor is concerned about future weight problems. Although children need fat for brain development, the group says that because children often consume so much fat, low-fat milk is now appropriate.
