H1N1 virus attacks deep into the lungs

By Stephanie Smith, CNN Medical Producer December 8, 2009

New York (CNN) -- In the rare cases when the H1N1 virus kills, scientists have found, it penetrates deep into the lungs, creating widespread damage -- a pattern similar to what killed millions during previous flu pandemics in 1918 and 1957.

The New York Office of Chief Medical Examiner examined medical records, autopsy reports and microscopic slides of 34 people with H1N1 who died between May 15 and July 9, 2009, during the early days of the pandemic.

The report found that among those deaths, inflammation and damage in the lungs extended all the way to the alveoli, tiny sacs at the farthest end of the lungs' airways.

"Generally, flu stays in the upper airways," said Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases. "What this shows is clearly this virus has capability of infecting and causing inflammation and destruction of cells from the trachea, all the way down into smaller cells of the lungs.

"The cells of the lung get directly attacked by the virus," said Fauci.

The damage appears in computerized scans as opaque patches that normally would not appear in the lungs, and which obstruct lung function.

Echoing previous reports, the study, published online in the Archives of Pathology and Laboratory Medicine, also revealed that 91 percent of those who died were people with underlying health problems, and most occurred in people between 25 and 49 years old.

More than half of the deaths were caused by bacterial pneumonia.

"The secondary bacterial infection evokes inflammation," said Dr. William Schaffner, professor in the Division of Infectious Diseases at Vanderbilt University School of Medicine. "It socks it in the lung and all of a sudden the lung as an organ can't do its principal job."

Obesity was a factor in 72 percent of H1N1 deaths, a finding that has caused concern among infectious disease experts.

"That was a striking finding," said Schaffner. "It contributes in a very material way to what we know about risks for a severe outcome with H1N1 infection. We are keeping an eye on obesity as a risk factor for H1N1 death."

The study gives interesting insight into the mechanism behind H1N1 deaths, but will not change the current response to the virus, said Fauci.

What really killed the beauty queen?

By Elizabeth Cohen, CNN Senior Medical Correspondent December 10, 2009

When Argentine beauty queen Solange Magnano approached Dr. Guillermo Blugerman in 2004 about helping her achieve a flatter stomach, the plastic surgeon says, he obliged with liposuction. But when she returned five years later requesting silicone injections for a higher, firmer rear end, he turned her away.

"I said this was not allowed to be done in Argentina," Blugerman said on the telephone from his Buenos Aires office.

Blugerman, the president of the Argentina Association of Medicine and Cosmetic Surgery said he believes Magnano then went in search of someone who would give her the injections she wanted.
"She found someone else to do this with this forbidden material," he said.

The former Miss Argentina died November 29, reportedly of a pulmonary embolism, a blood clot that blocks blood supply to the lungs. Embolisms are known complications of silicone injections though they can occur -- rarely -- after any surgery. It's still not clear Miss Argentina was given a silicone injection, which is not an approved procedure for "butt lifts" in Argentina or the United States.

If silicone injections caused Magnano's death, the lesson learned is an obvious one -- seek out unapproved medical procedures at your own peril -- but there are many other, more subtle tips for staying safe during plastic surgery.

The first rule is not to take plastic surgery lightly.

"Some people think of cosmetic surgery as not real surgery. They get the impression they're going to a spa," said Dr. Angelo Cuzalina, president-elect of the American Academy of Cosmetic Surgery. "It's still surgery. You get cut. You bleed."

While complications of plastic surgery are rare, they do happen. For example, for every 100,000 liposuction procedures in the United States, there are between three and 100 deaths, according to the Food and Drug Administration.

The second rule is to be your own investigator.

"It's my impression from being a surgeon that people don't ask enough questions," said Dr. Phil Haeck, president-elect of the American Society of Plastic Surgeons.

Colleen Fledderman learned that lesson the hard way.

When her 18-year-old daughter, Amy, wanted liposuction in her chin and stomach, she said the surgeon told them that Amy was "zero risk."

"I asked him if there was anything we needed to worry about, like blood clots to the brain, or anything like that, and he said absolutely not," Fledderman said.

The procedure was performed in 2001 in the King of Prussia, Pennsylvania, office of Dr. Richard Glunk. Later that day, Amy was transferred to the hospital, where she died two days later. Her autopsy listed complications of a fat embolism due to liposuction as the cause of death. Her parents filed a wrongful death lawsuit and won $20.5 million in damages against Glunk and a nurse anesthetist involved in the surgery. The case is on appeal to the Superior Court of Pennsylvania, where it's scheduled to be argued in January.

Glunk said he never told Amy that she was "zero risk" and that Amy was aware of the risks inherent in surgery, including the possibility of death. He said a fat embolism like the one that led to Amy's death is "a tragic, unpredictable, unpreventable event that has no treatment" other than supportive care.

"The informed consent was at all times with Amy. It was her understanding," Glunk said. "The instant that Amy had any problems, 911 was called."

Glunk said there's no doubt in his mind that the verdict against him will be reversed on appeal.

"Even though everything is going to get reversed in the courts, and it will technically be proclaimed that I did nothing wrong, I've had 8½ years of damage that will never be undone," he said. "Any time anyone has a severe complication with surgery it's a horrible tragedy, but the existence of a complication does not mean that a doctor did anything wrong."

While plastic surgery will never be risk-free, asking these five questions can help decrease the chances of a deadly complication.

1. "Doctor, are you board certified?"

You want a doctor who's certified by the American Board of Plastic Surgery. You can find one by going to the Web site of the American Board of Medical Specialties.

2. "Doctor, is your office accredited for performing this procedure?"

Most cosmetic procedures are not done in hospitals, but rather in outpatient clinics, according to Cuzalina of the American Academy of Cosmetic Surgery.

He recommends going to a clinic that's been accredited by a group such as the Joint Commission or the Accreditation Association for Ambulatory Health Care. These groups inspect facilities and make sure they're set up to safely perform surgical procedures.

"You're better off going to someone who cared enough to get the proper accreditation," Cuzalina said.

3. Doctor, what's your prevention plan for deep vein thrombosis?

One of the more common complications of plastic surgery is a DVT, where a blood clot forms in a deep vein, usually in the leg. The clot can then break loose and travel to the lungs, causing a pulmonary embolism.

Haeck of the American Society of Plastic Surgeons said doctors should have a plan to prevent DVTs, which may include wearing special stockings during surgery, walking as soon possible after surgery, and looking out for early warning signs of complications, such as leg pain or shortness of breath.

4. Doctor, do you have privileges at a hospital to perform this procedure?

Even though you likely won't be in the hospital, you want to know if a hospital has deemed your doctor skilled enough to perform the procedure in their facility.

"The hospital is the judge of the physician's abilities," Haeck said. "If a surgeon says he doesn't have privileges at a local hospital to do the procedure, that should be a red flag."

If the surgeon says he does have privileges, call the hospital and double-check.

5. Doctor, how many of these procedures have you done?

"Good surgeons expect you to research them and won't be afraid to answer personal or tough questions," Haeck said.

When you find out how many times a doctor has performed a procedure, go to other plastic surgeons and compare.

In addition to asking these five questions, here are two more tips. Beware of trying to do too much at once. Lumping together several procedures can increase the chances you're going to have a problem.

"With any major surgery, the longer the surgery and the more invasive the surgery, the higher your chances of developing a blood clot," Cuzalina said.

Also, make sure you talk to your doctor about whether you need to go off certain medications before surgery. For example, birth control pills and estrogen supplements increase your chance of getting a blood clot, and doctors often recommend stopping them several weeks before surgery.

Doctors also sometimes want patients to stop taking herbs such as ginkgo and concentrated garlic, which can lead to excessive bleeding.

Obama to Overturn Bush-epoch Stem Cell Strategy

Posted by editor1 CoolHealthTips.com

US President Barack Obama announced the overturn towards the stem cell policy of former US President George W. Bush. He further said that his government would follow science rather than political ideology. Obama is intended to turn around the limits on stem cell research being funded by federal government and handed over the command to National Institutes of Health to save the science and research from political interference.

In the former rule, there were limitations on the taxpayer money for stem cell research and stem lines were restricted to specific areas. Many of these lines were proved to have drawbacks and should be left while the new and healthy research lines should be funded to get benefits. Bush along with his supporters argued they did so to defend the human life by protecting days-old embryos which were destroyed for the stem cells.

On the other hand, the research supporters strongly favor the Obama’s decision. Stem cells of an embryo are the master cells which can be changed into any cell of the body.

Due to this quality, researchers want to use them for creating replacement tissues in order to cure a variety of diseases like new insulin-producing cells for diabetic patients or to restore movement after spinal injury by creating new nerve connections.

Obama is well aware of the both arguments and has urged the researchers to do research for the betterment of humanity.

American Spending on Alternative Medicine Continues to Skyrocket

By Drucilla Dyess

American consumers spent an estimated $34 billion on alternative medicine in 2007. In fact, alternative medicine accounts for over 11 percent of out-of-pocket spending on health care in the United States. This surprising information comes from the first national estimate of dollars spent on alternative medicine in over ten years. The last government estimate of spending on alternative medicine was reported based on a 1997 survey that found spending to be at about $27 billion.

Alternative medicine includes any healing practice not falling within the realm of conventional medicine. Many such practicies include herbalism, homeopathy, hypnosis, naturopathy, chiropractic, acupuncture, yoga, biofeedback, diet-based therapies, Unani and traditional Chinese medicine. These practices are very diverse and may be based upon traditional medicine, folk knowledge, spiritual beliefs, newly conceived approaches to healing or a combination thereof.

According to Dr. Josephine Briggs, director of the National Center for Complementary and Alternative Medicine, “We are talking about a very wide range of health practices that range from promising and sensible to potentially harmful.” She further explained that there is a critical need for more research into which therapies are effective due to the substantial amount of money consumers are spending on them.

Briggs also noted that as the number of uninsured Americans increases, the use of these therapies may grow even more as some of them are relatively inexpensive. Because the data gathered for the estimate was collected prior to the current recession, it is not know if the economy played a role in jump in alternative medicine spending.

The U.S. Centers for Disease Control and Prevention (CDC) surveyed more than 23,000 adults across the nation and found that over one-third of American adults use alternative medicine. A report of this information was released in December of 2008.

The newly released report on the survey revealed that pain was the primary reason people sought massages and chiropractic care as well as other alternative therapies. Approximately 35 cents of each dollar spent on alternative went for appointments with acupuncturists, chiropractors, massage therapists and other practitioners. With a total of almost $12 billion, this represents about one-fourth of what is spent on mainstream physicians.

The most popular supplements used were found to be glucosamine to battle against joint pain, and fish oil to reduce the risk of heart disease. A total of $15 billion, or 44 cents out of each alternative medicine dollar spent, went for such products as these and echinacea. This is about equivalent to one-third of what American consumers spend out-of-pocket for prescription drugs.

Regarding supplement use, Briggs said, “I personally am pretty conservative about supplement use.” She also said that the center’s research has played a role in consumer behavior regarding their use. For example, when studies revealed that echinacea was ineffective for colds, and that St. John's wort did not quell major depression, consumers use of these products dropped. On the other hand, the use of fish oil has increased following research indicating that it might help lower risk of heart problems. Although many consumers believe that all products that they purchase have been cleared by the Food and Drug Administration, the fact is that they do not need proof of safety or effectiveness to go on the market.

The survey also showed that a stunning $3 billion was spent on homeopathy. Homeopathy is a system of medical practice that treats disease through the administration of minuscule doses of a remedy that would produce symptoms in healthy persons when used in larger amounts.

Findings concluded that 38 million adults visited alternative medicine practitioners for which they paid less than $50 on average per visit, and the average annual spending per person was about $122. For services such as acupuncture, homeopathy and hypnosis, the average was a higher at $75 plus. The average spending for products was $177.
