History of Stethoscopes used by physicians

Stethoscopes  are the most widely used tool by physicians.  With them, we are able to listen to heart, lungs, arteries and intestines.  A physician is able to tell if there is heart disease, pneumonia, bronchitis, carotid stenosis, renal artery stenosis and a host of many other problems. The stethoscope that you commonly see draped around your doctor’s neck is a lot different than those first used.  Below is an old advertisement listing all the different models available  at that time.

Will a Cialis pill a day keep the Viagra away?

I don’t even know what to say about this one!  One of the main side effects of Cialis, Viagra and Levitra are headaches.  For once- it will be the husband who complains of a headache. Viagra became a household name once it became clear that men with erectile dysfunction could benefit from it.  As a matter of fact,  former Presdiential candidate Bob Dole even did a commercial about it. Within years, competitor Cialis and Levitra became popular alternatives.

NEW YORK (Reuters) – Eli Lilly and Co on Tuesday said U.S. regulators approved once-daily use of two low-dose forms of its Cialis anti-impotence drug, offering greater convenience for men expecting frequent sexual activity.

The Indianapolis drugmaker said the once-daily formulations, in dosages of 2.5 milligrams and 5 milligrams, will allow men to attempt sexual activity any time between doses.

“In clinical trials, when taken without restrictions on the timing of sexual activity, Cialis for once daily use improved erectile function over the course of therapy,” Lilly said in a release.

The low-dose daily formulations, already approved in parts of Europe, “may be most appropriate for men with erectile dysfunction who anticipate more frequent sexual activity (e.g. twice weekly),” Lilly said.

The company said the low-dose formulations provide “a new option for men who may be looking for a dosing option that can be taken without regard to timing of sexual activity.”

The treatment, which has global annual sales of $1.2 billion, has been available in the United States since 2003 in dosages of 5 milligrams, 10 milligrams and 20 milligrams, and taken as needed. Those dosages provide effectiveness for up to 36 hours.

Company spokeswoman Keri McGrath said no dosage forms of the medicine, including the newly approved lower ones, are appropriate for heart patients who take nitrates, including nitroglycerin.

Members of the class of drugs to which Cialis belongs — including Pfizer Inc‘s rival Viagra and GlaxoSmithKline Plc’s Levitra — can dangerously lower blood pressure when used alongside nitrates.

The drugs, used by millions of men worldwide, also carry new warnings about potential risk of sudden hearing loss.

Shares of Lilly were up $1.05, or 1.9 percent, to $55.60 in morning trading on the New York Stock Exchange, in line with a 2 percent advance for the drug sector.

Diet during mom’s pregnancy may worsen allergies and asthma in kids-

PARIS (AFP) – Women who follow the famous Mediterranean diet while pregnant may also be shielding their baby from childhood asthma and allergy, a study published on Tuesday says.

Doctors recruited 507 women who attended an antenatal clinic on the Mediterranean island of Menorca in 1997, and quizzed them at length about their dietary habits.

More than six years later, they examined the women’s children for asthma and wheezing and carried out a skin-prick test to see if the youngsters had a response to six common allergens.

The investigation found that the children’s dietary intake at this age appeared to have little impact on whether they had these problems.

What made a difference, though, was what their mothers had eaten while pregnant.

One third of the mums-to-be had a low rating on the Mediterranean Diet Score, a measurement of consumption of fruits and vegetables, olive oil, fish, wholegrain cereals, legumes and nuts. Two-thirds had a high score.

Children from the “low score” group were between three and four times likelier to develop asthmatic symptoms than counterparts from the “high score” group, and almost twice as likely to develop allergies.

Consumption of vegetables more than eight times a week, fish more than three times a week, and beans or peas more than once a week seemed to be especially protective.

But consumption of red meat more than three or four times a week seemed to boost the risks.

The paper, published in the specialist British journal Thorax, points to two key components of the Mediterranean diet: antioxidants — vitamin compounds that mop up damaging molecules called free radicals — and polyunsaturated fatty acids, typically found in olive oil and fish oil.

Antioxidants are known to have a protective effect against asthma in young children, while the fatty acids shield against inflammation, a key factor in the complex problem of asthma, say the authors.

The Mediterranean diet, which is also associated with longevity, also incorporates moderate amounts of red wine.

Alcohol consumption is prohibited in pregnancy and was not included in the study.

The research was headed by Leda Chatzi, a doctor at the Department of Social Medicine at the University of Crete, Greece..

Heart grown in a jar-

 One day when a person needs a heart transplant- they may be searching for one in a used pickle jar! That is right! Scientists are now starting to grow hearts in a jar….

WASHINGTON – Researchers seeking new treatments for heart disease managed to grow a rat heart in the lab and start it beating.

“While it still sounds like science fiction, we’ve hopefully opened a new door in the notion that we can build these tissues and one day provide options for patients with end-stage disease,” said Dr. Doris Taylor, director of the Center for Cardiovascular Repair at the University of Minnesota. “We’re not there yet, but at least now we have another tool in our tool belt.”

Taylor led the team whose research appeared in Sunday’s online edition of the journal Nature Medicine.

Scientists have worked for years for ways to grow body parts. Many efforts have focused on heart valves as an alternative to the plastic or animal valves that wear out after being implanted in humans.

An estimated 5 million people live with heart failure and about 550,000 new cases are diagnosed each year in the United States. Approximately 50,000 die annually waiting for a heart donor…. Read the entire story.
