No stethoscopes, antibiotics, X-rays or vaccines. Bloodletting was a common treatment. If you had a heart attack or a stroke, doctors put you in bed and hoped for the best. If you needed surgery, you got a few shots of whiskey and a bullet to bite.

Into this medical dark age, two Boston doctors brought a beacon of light. They started what is now the New England Journal of Medicine with the idea that science should guide care — not whoever argued loudest or had the most persuasive theory.

The first 100 copies in January 1812 were delivered by horseback. Today, 2 million people read the journal online every month. It is the oldest continuously publishing medical journal in the world, and it has touched lives in more ways than you may know. Some examples:

—Stroke victims now get clot-busting medicine, not dark rooms to ride out their brain trauma, because a 1995 study in the journal proved its benefit.

—Heart attack patients have arteries unclogged without surgery, then go home on medicines that studies in the journal showed could prevent future attacks.

—Women with early stage breast cancer can have just the lump removed followed by radiation instead of losing the whole breast, thanks to a 1985 study that found the lesser surgery just as good.

—Bone marrow and organ transplants — radical ideas when first tried half a century ago — are now routine. Even face transplants are becoming more common: three were described in last week's issue.

—Rehydration is now recognized as the main treatment for many diarrheal diseases. A journal article warned against bloodletting in 1832 as cholera ravaged New York City.

—People no longer suffer surgery without anesthesia, a field that grew from Henry Jacob Bigelow's 1846 report on the first successful use of inhaled ether.

—Medicine is more ethical, and study participants have more protections, because of a 1966 report in the journal about researchers failing to get informed consent. Another top journal had rejected the article as too controversial.

The New England Journal started decades before the American Medical Association was founded in 1847 and is widely credited with promoting evidence-based care.

"It has been very good for society," said Pat Thibodeau, head librarian and associate dean for the Medical Center Library at Duke University. "When I go in, I'm hoping my doctor has read the New England Journal of Medicine or something similar and is following that information."

"It's the cream of the crop," said Dr. Barron Lerner, a Columbia University physician and medical historian.

"They get the best research submitted to them, and they do an extremely good job of peer reviewing" to make sure it is solid, he said.

That's what Boston surgeon John Collins Warren and James Jackson, who helped found Massachusetts General Hospital, hoped for the journal, which is now published weekly. It got its current name in 1928, seven years after it was bought by the Massachusetts Medical Society.

Warren's father, John Warren, surgeon to George Washington's troops, wrote the first article, on chest pain. Doctors had been debating whether it was caused by plaque — "the cement that builds up in arteries" — or blood clots, said Dr. Jeffrey Drazen, the journal's editor-in-chief since 2000. Both proved correct — the "cement" fractures and allows a clot to form that blocks an artery, he said.

Heart care has been a journal specialty, and two prominent doctors — Elizabeth Nabel and Eugene Braunwald of Brigham and Women's Hospital — trace its evolution in this week's issue. Nabel is former director of the National Heart, Lung and Blood Institute and now is president of the Boston hospital.

They describe the first human cardiac catheterization — now a common diagnostic procedure — that Werner Forssman performed on himself in 1929. Under local anesthesia, he put a catheter into his arm and maneuvered it into his own heart.

For a heart attack, "it used to be that all we did was put people to bed for five weeks," but studies in the journal showed "that that was the worst thing you could do," said Dr. Jerome Kassirer, its top editor from 1991 to 1999.

The journal also helped prove "germ theory" and the nature of infectious diseases.

"People didn't realize you could infect people when you were using your dirty gloves or not using gloves. People didn't realize tuberculosis was communicable. They thought it emanated from clouds they called miasma, clouds of dirty smoke in cities," said Lerner, the Columbia historian.

Not all was grand in the journal's history, though, as Allan Brandt, a Harvard University medical historian writes in this week's issue.

When Harvard Medical School debated admitting female students in 1878, the journal expressed concern about men and women mingling during surgeries normally witnessed only by one sex. The school didn't admit women until 1945, when World War II caused a shortage of men.

The journal also agreed with mandatory sterilization of "mental defectives" in the early 20th century. "Most alarming," Brandt writes, was its declaration in 1934 that "Germany is perhaps the most progressive nation in restricting fecundity among its unfit." The journal later condemned Nazi medicine.

In recent years, it has tracked health policy, from the Clinton health care plan and the advent of managed care to current debates about Medicare.

There were oddball reports along the way, like the 2007 account of a cat named Oscar that had a knack for predicting when patients at a Providence, R.I., nursing home were close to death by curling up to them in their final hours.

The journal has printed few studies on alternative medicine because so little good research has been done on it, Drazen said. Unlike some other journals that like controversial research, the New England Journal tries to avoid it.

"People think the cutting edge is sharp. The cutting edge is very dull. It's very foggy and you don't know what the right answer is," so editors try to pick studies that are definitive enough to affect care, Drazen said.

That's why it publishes very few observational studies, the kind that in the 1990s led to pronouncements like "margarine is better than butter" only to be reversed by the next such study.

"Some of those are papers that we've seen and turned back," Drazen said. "I'm looking for a higher evidence standard."

England bans cigarette machines

AppId is over the quota
AppId is over the quota
1 October 2011 Last updated at 07:59 GMT A cigarette vending machine Vending machines are expected to be banned in Wales, Northern Ireland and Scotland in February The sale of tobacco from vending machines has been banned in England, with anyone caught selling cigarettes in machines facing a fine of £2,500.

The Department of Health said the ban had been introduced to prevent under-age sales to children and to support adults who were trying to quit.

The rest of the UK is expected to implement a similar ban next year.

Some pub landlords say it is a further threat to a livelihood that has already been damaged by the smoking ban.

But Cancer Research and the British Heart Foundation have welcomed the move.

According to the Department of Health, nearly all adult smokers started smoking before they turned 18.

'Unsupervised'

Of the children who regularly smoke, 11% buy their cigarettes from vending machines.

It is also estimated that 35 million cigarettes are sold illegally through vending machines to children every year.

Under the new rules, pub landlords will still be able to sell cigarettes from behind the bar but they must ensure all tobacco advertising on vending machines is removed. Any person found guilty of displaying cigarette adverts on a vending machine could face imprisonment for up to six months, a fine of £5,000, or both.

Health Secretary Andrew Lansley said smoking was "one of the biggest and most stubborn challenges in public health", with more than eight million people in England still smoking, causing more than 80,000 deaths each year.

Continue reading the main story
When [smokers have] got to stand in the street and they can't even buy their cigarettes in the pub, then where is it left? There's no point in them going to a pub. ”

End Quote Bill Sharp Pub landlord He said: "Cigarette vending machines are often unsupervised, making it easy for children to purchase cigarettes from them.

"The ban on cigarette sales from vending machines will protect children by making cigarettes less accessible to them - we want to do everything we can to encourage young people not to start smoking in the first place."

Jo Butcher, the National Children's Bureau's programme director of health and wellbeing, welcomed the ban and said a person's lifetime smoking or non-smoking behaviour was "heavily influenced" by decisions in their adolescence.

"Children and young people tell us that external influences make it even more difficult for them to choose healthier lifestyles.

"It's essential that we create environments that improve health and tobacco legislation is an important part of public health protection and promotion," she said.

Protection

Charities have also welcomed the ban.

Betty McBride, director of policy and communications at the British Heart Foundation, said thousands of children at risk of this "deadly addiction" regularly got tobacco from vending machines, "which conveniently don't ask them to prove their age".

"These children are often blissfully unaware of the damage smoking does to their health and, by the time they realise, they're hooked.

"Scrapping these machines cuts off an easy source of tobacco for existing young smokers and makes it harder for a new generation to start.

"We're encouraging landlords to remove machines completely now so they - and any left-over branding - don't act as dusty old adverts for tobacco," she said.

Eileen Streets, director of tobacco control at the Roy Castle Lung Cancer Foundation, said she hoped the ban would play a "significant part in stopping many children becoming the next generation of lung cancer victims".

Other measures

Jean King, of Cancer Research UK, added: "Tobacco kills half of all long-term users and is responsible for one in four cancer deaths.

"Cancer Research UK is determined to protect children from tobacco marketing and through our Out of Sight Out of Mind campaign we are continuing to work for legislation to introduce plain packaging for cigarettes."

But the British Beer and Pub Association described the ban as "an unnecessary measure".

A spokesman said the machines were there for the convenience of adult customers, and that the association did not believe they played a role in childhood smoking.

Although cigarettes can be sold by bar staff, the spokesman said many pubs would not opt to introduce that, as it raised issues about having a "high-value" item behind the bar and interfered with serving drinks.

One London pub landlord, Bill Sharp, said the ban was another "nail in the coffin" of his livelihood.

"I can understand them removing it from public places because that's a view, a health issue, call it what you will.

"But when [smokers have] got to stand in the street and they can't even buy their cigarettes in the pub, then where is it left? There's no point in them going to a pub. They going remove real ale from pubs next?"

Other measures to protect young people from the dangers of smoking are also on the way.

In April 2012, large retailers in England and Scotland will have to get rid of all tobacco displays. Small shops will be expected to comply from April 2015.

Wales and Northern Ireland plan to implement similar regulations.

The government is also due to begin a public consultation before the end of the year on whether to introduce plain packaging for cigarettes in order to lessen their marketing appeal to young people, help make health warnings more effective and help reduce the number of smokers.
