If people want to burn fat, detoxify livers, shrink prostates, avoid colds, stimulate brains, boost energy, reduce stress, enhance immunity, prevent cancer, extend lives, enliven sex or eliminate pain, all they have to do is walk in to a vitamin store and look around.

The shelves will be lined with ginkgo or rose and orange oils touted as aids for memory; guarana and cordyceps for energy; chicory root for constipation; lemon balm oil, ashwagandha, eleuthero, Siberian ginseng and holy basil for stress; sage and black cohosh for menstrual pain; coconut oil and curry powder for Alzheimer’s disease; saw palmetto for prostate health; sandalwood bark to prevent aging; garlic for high cholesterol; peppermint oil for allergies; artichoke extract and green papaya for digestion; echinacea for colds; chondroitin sulfate and glucosamine for joint pain; milk thistle for hepatitis; St. John’s wort for depression; and tongkat ali for sexual potency.

The question, however, is: Which products work? And how do we know they work? Fortunately, thanks to James Lind, we can figure it out.

When Lind climbed aboard the HMS Salisbury intent on testing whether citrus was a cure for scurvy in 1740, he moved medicine from a faith-based system to an evidence-based system. No longer do we believe in treatments. We can test them to see whether they work.

Although the size and cost of clinical studies have increased dramatically since the days of Lind, the claims made about alternative remedies are testable, eminently testable.

In that sense, there’s no such thing as alternative medicine. If clinical trials show that a therapy works, it’s good medicine. And if a therapy doesn’t work, then it’s not an alternative.

For example, Hippocrates used the leaves of the willow plant to treat headaches and muscle pains. By the early 1800s, scientists had isolated the active ingredient: aspirin. In the 1600s, a Spanish physician found that the bark of the cinchona tree treated malaria. Later, cinchona bark was shown to contain quinine, a medicine now proven to kill the parasite that causes malaria. In the late 1700s, William Withering used the foxglove plant to treat people with heart failure. Later, foxglove was found to contain digitalis, a drug that increases heart contractility. More recently, artemisia, an herb used by Chinese healers for more than a thousand years, was found to contain another anti-malaria drug, which was later called artemisinin.

“Herbal remedies are not really alternative,” writes Steven Novella, a Yale neurologist. “They have been part of scientific medicine for decades, if not centuries. Herbs are drugs, and they can be studied as drugs.”

Looking at the claims

In many case, though, when natural products have been put to the test, they’ve fallen short of their claims. For instance, although mainstream medicine hasn’t found a way to treat dementia or enhance memory, practitioners of alternative medicine claim that they have: ginkgo biloba. As a consequence, ginkgo is one of the 10 most commonly used natural products.

      Some medicines that end up in the world’s wa­ter­ways af­ter be­ing used are af­fect­ing fish be­hav­ior, ac­cord­ing to a new stu­dy.


Tomas Brodin of Swe­den’s Umeå Uni­vers­ity and col­leagues found that wild Eu­ro­pe­an perch ate faster, be­came bolder and acted less so­cial af­ter ex­po­sure to an anxiety-moderating drug known as Ox­aze­pam.

      Residues of the drug of­ten wind up in nat­u­ral aquat­ic sys­tems af­ter peo­ple con­sume it, the re­search­ers said. They’re ex­cret­ed, flushed down the toi­let, trea­ted at wastewa­ter treat­ment plants, and end up in the wa­ter un­changed.


Brodin and col­leagues dosed wild perch with amounts of Ox­aze­pam equiv­a­lent to those found in Swe­den’s riv­ers and streams. Their re­sults, they said, sug­gested that even small amounts of the drug can al­ter the be­hav­ior and for­ag­ing ra­tes of these fish. 


“Nor­mally, perch are shy and hunt in schools. This is a known stra­tegy for sur­viv­al and growth. But those who swim in Ox­aze­pam be­came con­sid­erably bold­er,” said Brodin, lead au­thor of the re­port, pub­lished in the Feb. 15 is­sue of the jour­nal Sci­ence. The af­fect­ed fish left their schools to seek food on their own, a be­hav­ior that can be risky, he ex­plained; they al­so ate more quick­ly.


“We’re now go­ing to ex­am­ine what con­se­quenc­es this might have. In wa­ters where fish beg­in to eat more ef­fi­cient­ly, this can af­fect the com­po­si­tion of spe­cies, for ex­am­ple, and ultima­tely lead to un­ex­pected ef­fects, such as in­creased risk of al­gal bloom­ing,” said Brodin.


“The so­lu­tion to the prob­lem is not to stop med­i­cat­ing ill peo­ple but to try to de­vel­op sew­age treat­ment plants that can cap­ture en­vi­ron­men­tally haz­ard­ous drugs,” added en­vi­ron­men­tal chem­ist Jerk­er Fick, a co-au­thor of the stu­dy.


The sci­en­tists added that the find­ings should be seen as a point­er about what might be un­der­way in many wa­ters around the world, though full­er stud­ies are re­quired be­fore any far-reach­ing con­clu­sions can be drawn.

Genetically engineered virus kills cancer


Genetically engineered virus kills cancer

Sixteen patients given a high dose of the therapy survived for 14.1 months on average, compared to 6.7 months for the 14 who got the low dose.

“For the first time in medical history we have shown that a genetically engineered virus can improve survival of cancer patients,” study co-author David Kirn told AFP.

The four-week trial with the vaccine Pexa-Vec or JX-594, reported in the journal Nature Medicine, may hold promise for the treatment of advanced solid tumours.

“Despite advances in cancer treatment over the past 30 years with chemotherapy and biologics, the majority of solid tumours remain incurable once they are metastatic (have spread to other organs),” the authors wrote.

There was a need for the development of “more potent active immunotherapies”, they noted.

Pexa-Vec “is designed to multiply in and subsequently destroy cancer cells, while at the same time making the patients’ own immune defence system attack cancer cells also”, said Kirn from California-based biotherapy company Jennerex.

“The results demonstrated that Pexa-Vec treatment at both doses resulted in a reduction of tumour size and decreased blood flow to tumours,” said a Jennerex statement.

“The data further demonstrates that Pexa-Vec treatment induced an immune response against the tumour.”

Pexa-Vec has been engineered from the vaccinia virus, which has been used as a vaccine for decades, including in the eradication of smallpox.

The trial showed Pexa-Vec to be well tolerated both at high and low doses, with flu-like symptoms lasting a day or two in all patients and severe nausea and vomiting in one.

The authors said a larger trial has to confirm the results. A follow-up phase with about 120 patients is already under way.

Pexa-Vec is also being tested in other types of cancer tumours.

A patient undergoes a scanner as radiology technicians look at the exam on a screen, on February 6, 2013, at a medical unit specialised in cancer treatment in France. A genetically-engineered virus tested in 30 terminally-ill liver cancer patients significantly prolonged their lives, killing tumours and inhibiting the growth of new ones, scientists reported on Sunday.

Mystery Brain Disease Strikes Women in US


Doctors have been wrestling with a newly discovered illness that attacks mainly young women and looks a lot like psychosis. In Philadelphia, hospitalized women appeared possessed, crying or laughing hysterically one moment and turning catatonic the next. One had seizures and left her arms stuck out in front of her. Finally doctors realized they weren’t crazy—they were suffering from an auto immune disease known as Anti-NMDA Receptor Encephalitis, reports CBS Philadelphia.

Discovered six years ago, the illness strikes the brain with antibodies and causes it to swell—as one doctor explained to two nervous parents: “He told them her brain is on fire,” says a woman who was hospitalized for weeks. “He used those words: ‘Her brain is on fire.'” A spinal fluid test can spot the disease and immunotherapy can treat it, but there is no cure; all patients face possible relapses. Now a former patient is trying to get the word out, explaining that “there could be people in comas right now or people stuck in psych wards that have this disease and aren’t being treated properly.”

Antioxidants May Actually Be Causing Cancer

James Watson Says Antioxidants May Actually Be Causing Cancer

Celebrated geneticist James Watson, one of several researchers who won the Nobel Prize for discovering the structure of DNA, has just published what can only be called a cancer manifesto in Open Biology. It’s full of fairly harsh criticisms for current cancer researchers, but also suggests several ways forward in the “war on cancer.” Among other claims, Watson asserts that antioxidants like vitamin C — often recommended as cancer-prevention supplements — could be causing some forms of cancer. He also has harsh words for personalized medicine, and the laziness of cancer researchers.

Watson, now in his 80s, has spent a great deal of his life raising money to fund cancer research at Cold Spring Harbor Laboratory, where he’s served as director since the late 1960s. Clearly anticipating his own mortality, he mourns the lack of good leadership in cancer research:

That we now have no General of influence, much less power, say an Eisenhower or even better a Patton, leading our country’s War on Cancer says everything. Needed soon is a leader that has our cancer drug development world working every day and all through the night.

He suggests that the problem is researchers are slacking, only putting in “never frantic, largely five-day working week[s].”

He goes on to say that the current craze for “personalized medicine” that will treat cancer is just not going to work. But the main problem comes from government money being misspent:

The now much-touted genome-based personal cancer therapies may turn out to be much less important tools for future medicine than the newspapers of today lead us to hope. Sending more government cancer monies towards innovative, anti-metastatic drug development to appropriate high-quality academic institutions would better use National Cancer Institute’s (NCI) monies than the large sums spent now testing drugs for which we have little hope of true breakthroughs. The biggest obstacle today to moving forward effectively towards a true war against cancer may, in fact, come from the inherently conservative nature of today’s cancer research establishments.

He goes on to say that conventional thinking about cancer is all wrong. Antioxidants may be undermining cancer therapies and even causing cancer:

In light of the recent data strongly hinting that much of late-stage cancer’s untreatability may arise from its possession of too many antioxidants, the time has come to seriously ask whether antioxidant use much more likely causes than prevents cancer.

All in all, the by now vast number of nutritional intervention trials using the antioxidants β-carotene, vitamin A, vitamin C, vitamin E and selenium have shown no obvious effectiveness in preventing gastrointestinal cancer nor in lengthening mortality. In fact, they seem to slightly shorten the lives of those who take them. Future data may, in fact, show that antioxidant use, particularly that of vitamin E, leads to a small number of cancers that would not have come into existence but for antioxidant supplementation. Blueberries best be eaten because they taste good, not because their consumption will lead to less cancer.

It is thought that antioxidants can prevent damage to DNA from oxygen radicals. But, argues Watson, we want oxygen radicals in cancer cells because this can cause the cells to die. Taking antioxidants might be preventing cancer drugs from destroying cancer cells. Instead, he recommends patients combine anti-antioxidants with cancer drugs.

Watson also recommends an area of research, into a class of proteins called RNAi, which can be used to shut down the activity of genes. He claims that we need less than a billion dollars to win the war on cancer if we focus on RNAi research:

The total sum of money required for RNAi methodologies to reveal the remaining major molecular targets for future anti-cancer drug development need not be more than 500–1000 million dollars. Unfortunately, the NCI now is unlikely to take on still one more big science project when it is so hard-pressed to fund currently funded cancer programmes … Further financial backing, allowing many more cancer-focused academic institutions to also go big using RNAi-based target discovery as well as to let them go on to the early stages of subsequent drug discovery, is not beyond the might of the world’s major government research funding bodies nor that of our world’s many, many super billionaires. The main factor holding us back from overcoming most of metastatic cancer over the next decade may soon no longer be lack of knowledge but our world’s increasing failure to intelligently direct its ‘monetary might’ towards more human-society-benefiting directions.

Watson also wants researchers to focus on a protein called Myc, which is believed to regulate the activity of 15% of our genes. Its activity is also linked to many kinds of cancer. Using RNAi methods, it’s possible we could figure out a way to control Myc, and thus shut down pathways to cancer.

Woman Grows Ear on Arm


US woman grows new ear on arm
Alys Francis, ninemsn
Sherrie Walter grew a new ear on her arm.
Sherrie Walter grew a new ear on her arm.

US doctors have grown a new ear for a woman on her arm after she lost her original ear during a battle with skin cancer.

Sherrie Walter had to have most of her left ear removed, along with parts of her skull and ear canal, in 2010 after she was diagnosed with a basal cell carcinoma, The Baltimore Sun reports.

The 42-year-old mother-of-two, from California, was left disfigured until doctors at Johns Hopkins Hospital in Maryland told her about a groundbreaking new procedure that would enable her to grow a new ear.

The ear was made using cartilage from Ms Walter’s ribs and arteries and from other parts of her body — the structure was then placed under the skin on her arm for four months to grow before it was transferred to her head.

Doctors said the entire process took close to 20 months and it is believed to be the most complicated ear reconstruction completed in North America.

Surgeons performed Ms Walter’s final major surgery last week, fashioning an earlobe and shaping the ear to look more natural.

Speaking before the operation, Ms Walter said: “I am one step closer to the end, to looking normal again.”

Ms Walter first noticed her skin cancer in 2008 when a scab on her ear would not heal.

After drastic surgery to remove the cancer and weeks of radiation, Ms Walter said she became self-conscious of her appearance and grew her hair long to try and hide her face.

She could not wear a clip-on prosthetic ear because parts of her skull had also been removed.

But Dr Patrick Byrne, who led Ms Walter’s surgical team, assured her there were other options and suggested she try the procedure to grow a new ear.

“It seemed a little strange but I was willing to try it,” she said.

Dr Byrne said the new ear should last for years to come.

US scientists are helping pioneer efforts to grow ears, bones and skin in laboratories, with doctors planning to use cutting-edge reconstructive techniques for wounded troops.

Alzheimer’s Epidemic Looms | Medical Mystery


Alzheimer’s remains medical mystery as epidemic looms

by Mariette le Roux

As the population ages, finding a cure for Alzheimer’s disease is increasingly imperative – but there will be a number of hurdles to overcome along the way.

More than 100 years after it was first caught in the act of decaying a patient’s brain, Alzheimer’s disease remains one of medicine’s greatest challenges as it robs ever more people of their memory and independence.

Researchers make halting progress, reporting small steps forward along with many frustrating setbacks.

And while care for Alzheimer’s sufferers has improved since former U.S. president Ronald Reagan and British fantasy author Terry Pratchett helped lift the stigma, the key workings of the illness remain a riddle.

Alzheimer’s disease causes two-thirds of dementia cases – attacking one in 200 people – and finding a cure has never been more pressing as the world’s population grows and ages.

“There is going to be a tsunami in terms of [cost] burden,” Dean Hartley, director of science initiatives at the U.S. Alzheimer’s Association, said ahead of World Alzheimer’s Day on September 21.

A door to hope slammed last month when drug giants Eli Lilly, Pfizer and Johnson & Johnson stopped tests of eagerly anticipated therapies that failed in clinical trials.

On September 6, French researchers announced plant extract gingko biloba, widely marketed as a natural Alzheimer’s remedy, did not actually prevent dementia.

Blaming insufficient funding, at least in part, researchers say they still do not know quite what to make of the plaques and tangles that German doctor Alois Alzheimer first spotted in the brain of a dementia patient who died in 1906.

Little follow-up work was done until the 1960s, partly because fewer people were then living to an age when the disease shows up.

Today, the sole drugs shut in our arsenal treat some symptoms but are powerless to slow the progression of Alzheimer’s.

“People are absolutely desperate for medicines – people suffering from the disease, and people close to them,” said Eric Karran, research director at Alzheimer’s Research UK.

“Where we are at the moment is a critical period for this disease,” he added.

“The pharmaceutical industry has had a range of very, very expensive failures. I worry they might be thinking: ‘this is very difficult and we will just have to wait until the science is more evolved’.”

Hartley and Karran said Alzheimer’s received a fraction of the money governments spend on disease research despite being one of the costliest illnesses in terms of suffering and spending.

Costs and complexity

Alzheimer’s Disease International (ADI) projects the number of people with dementia will rise from 35.6 million in 2010 to 65.7 million by 2030 and 115.4 million by 2050.

The cost, including hospital and home care, drugs and clinic visits, is expected to soar some 85% by 2030 from about US$600 billion in 2010 – roughly the GDP of Switzerland.

But money is not the only problem.

The disease is a particularly complicated one to crack, not least because its effect on humans is nigh impossible to replicate in lab animals.

Its slow progression is an added hurdle.

“The disease seems to be present in people’s brains maybe 15 years prior to … suffering symptoms,” said Karran.

Alzheimer’s normally becomes apparent around the age of 70, when family members observe a loved-one becoming forgetful and confused.

“When patients are available to be studied in clinical trials, you are actually looking at a disease that has been going on for 15 years,” by which stage neurons would already have died, said Karran.

Scientists disagree on the respective roles of beta amyloid plaque build-ups and of a protein called tau, which forms tangles inside these brain cells.

Most test therapies have targeted beta amyloids, but some now suggest it is actually tau killing the brain cells.

“We still do not understand the relation between the structural damage and cognitive symptoms exactly,” Dutch neurophysiology PhD student Willem de Haan said.

Researchers are aiming for a treatment that will halt the disease at an early stage – even before the onset of symptoms.

And while they have not succeeded, their work is throwing up some valuable clues along the way.

Already known is that a small percentage of people, more women than men, are genetically predisposed to developing Alzheimer’s. A family history of the disease boosts the risk.

Some studies suggest healthy living may reduce the chances of those people who do not carry Alzheimer’s-related genes of developing the disease.

Diagnostics, too, are improving: new research shows that a simple eye-tracking test and sleep disruption may be early indicators, helping victims make lifestyle choices before the disease steps into higher gear.

The experts believe that if governments, researchers and drug companies work together efficiently, a treatment may be available within 20 years.

But they also warn against giving false hope to desperate people.

“Finding a medicine for a chronic disease is far, far more complicated than, say, putting a man on the Moon,” said Karran

Jewish Prayerbooks Full Of Crap – Literally!


Kotel Prayerbooks Full Of Crap, Study Finds

Contamination found in Kotel prayer books
Public Health Association discovers bacteria contamination in samples from Western Wall prayer books. Site’s Rabbi: Cause is women’s crying
Dr. Itay Gal • Ynet

A recent examination of communal prayer books in the Western Wall shows large numbers of fecal bacteria, a contamination that far exceeds the normal rate.

The contamination was found in books both from the women’s section and the men’s section. Still, the Western Wall’s rabbi argues that the blame is solely on the women that tend to hold the books close to their faces and shed tears.

The test comprised of samples taken from prayer books from both sides of the partition. The samples revealed extremely large numbers of fecal bacteria colonies including E. coli and other coliform bacteria.

One sample had 460,000 colonies (1000 being the normal rate) and another had 540,000 colonies of bacteria, in addition to high concentration of mold.

High concentration of bacteria can lead to inflammatory bowel, abdominal pain, diarrhea, fever, and sometimes even to life threatening infections.

Although the books are used by men and women alike, the holy site’s rabbi, Shmuel Rabinovitch placed the blame solely on the women. He claimed that hundreds of women cry every day into the books, causing contamination.

The rabbi added that the power of women’s prayer is often stronger than men’s thanks to their tears, excitement and spiritual transcendence.

The rabbi said that the prayer books in the site are frequently replaced, but reaffirmed that following the conclusions of the examination the books will be replaced more often.

Israel’s Association of Public Health saluted Rabbi Rabinovitch for his cooperation and quick response.

Years After Acid Attack Horror, Suicide Stirs Pakistan


Years After Acid Attack Horror, Suicide Stirs Pakistan

Declan Walsh in the New York Times:

ScreenHunter_06 Apr. 10 11.55

Fakhra Younas went under the surgeon’s knife 38 times, hoping to repair the gruesome damage inflicted by a vengeful Pakistani man who had doused her face in acid a decade earlier, virtually melting her mouth, nose and ears.

The painful medical marathon took place in Rome, a distant city that offered Ms. Younas refuge, the generosity of strangers and a modicum of healing. She found an outlet in writing a memoir and making fearless public appearances.

But while Italian doctors worked on her facial scars, some wounds refused to close.

On March 17, after a decade of pining for Pakistan, a country she loved even though its justice system had failed her terribly, Ms. Younas climbed to the sixth-floor balcony of her apartment building in the southern suburbs of Rome and jumped. She was reported to be 33 years old.
