Bird flu tops WebMD's list of the top health news stories of 2005, but a pyramid, natural disasters, and a movie star left their mark in a big way, too.
It's been a busy year for the WebMD newsroom. Here's our editors' pick of the top 10 stories.
1. Bird Flu Takes Wing
It's the biggest health story of the year -- and it hasn't happened yet.
Unlike human flu bugs, the hasn't yet learned to spread from person to person.
What do you need to know? WebMD puts bird flu into , and you need to ask -- including whether is inflating bird flu fears.
What will we see in the coming year? Bird flu already is popping up in Europe. As wild birds carry the bird flu virus around the world, it may only be a matter of time before the bug hits birds in Africa and America. Scientists are racing to test a for humans and to develop faster, better flu vaccines.
WebMD's Special Report brings you all the facts about bird flu.
2. The Terri Schiavo Saga -- End of Life and Living Wills
After having her feeding tube removed, Terri Schiavo died. Whether the brain-damaged Florida woman would have wanted it this way -- or whether she would have preferred to be kept alive at all costs -- remains a matter of dispute.
That dispute -- between family members -- played out in the most public of ways as the U.S. Congress and Florida Governor Jeb Bush sought to intervene. No matter how we felt about the dispute, Schiavo's sad story made all of us think about -- and about seeing to our own .
As intimate details of Schiavo's life and death became public, there was some evidence that her collapse may have been due to an . Whether this was the case or not, the story again served to focus our attention on an underappreciated health issue.
Painkillers in the News
3. Black Boxes and Pain Drugs
Remember when you used to pop an over-the-counter pain pill without a second thought? Those days ended this year.
These drugs, known as Cox-2 inhibitors or coxibs, aren't more powerful than older anti-inflammatory pain drugs such as ibuprofen and naproxen. They are designed to be easier on the stomach than ibuprofen, naproxen, or aspirin. But a recent benefit.
The concerns about the Cox-2 drugs extend to all prescription anti-inflammatory drugs, which are commonly used to treat arthritis and other painful conditions. The FDA recently asked the makers of these drugs to add to their labels about heart, stroke, and ulcer risks.
Short-term, low-dose use of over-the-counter anti-inflammatory drugs, such as ibuprofen and naproxen, do not appear to increase the risk of heart attacks and strokes. But patients should check with their doctors before taking these drugs for more than 10 days.
The FDA's highest safety warning for approved drugs, a "black box" warning, was added to the following:
- , due to rare reports of suicidal thinking.
- Celebrex and all other prescription NSAIDs (non-steroidal anti-inflammatory drugs), due to heart concerns.
- , because of fears they may increase the risk of skin cancer and lymphoma.
- due to the possible risk of rare but potentially serious infections associated with the drug.
The FDA has also asked the independent Institute of Medicine for recommendations on how it might improve drug safety. An IOM panel of experts began holding hearings in 2005.
4. Contraceptives Questioned
The concern over the birth control patch followed on the heels of a black box warning late last year about , a long-lasting injectable contraceptive.
Half of unplanned pregnancies occur in women not using birth control. These women might still prevent pregnancy by using the morning-after pill, sold as Plan B. But Plan B has to be taken very soon after unprotected sex.
In 2003 an FDA advisory panel recommended approving Plan B for over-the-counter sale. In 2004 FDA officials said no. And in 2005, the by saying it needed more time to consider how to make the drug available to adults while keeping it out of the hands of girls under 17.
Mental Health in the Spotlight
5. Tom Cruise Condemns Antidepressants
The Hollywood star told his fans -- and everyone else -- that psychiatric drugs are harmful, not helpful. He criticized actress for taking antidepressants for postpartum depression.
There are, of course, and other drugs in the treatment of mental illness. And there are, indeed, risks from taking any drug, including antidepressants. But psychiatrists tell WebMD patients should discuss their concerns with their doctors before taking the advice of Cruise.
6. Medicare on the Mind
For Americans over 65, 2005 has handed them a big decision about Medicare's prescription-drug benefit. And whether to enroll in the program -- known as Medicare Part D -- is only the first part of the problem.
Medicare's future continues to be debated. The federal health program faces , as an aging U.S. population collides with burgeoning health care costs and .
The U.S. House and Senate each passed very different Medicare/Medicaid plans. Both bills cut Medicare spending.
The Senate bill focuses on cutting costs paid to insurers and drug companies -- although it expressly forbids the government from with manufacturers. The House bill would put more responsibility on beneficiaries, with an eye to lowering health care costs by giving patients incentives to keep health expenses in check.
Many in Congress would like to see Medicare become more like private health insurance. In this scenario, Medicare would become more of a premium-support plan. The idea is to cut costs by increasing market competition among insurance providers. Others would like to see Medicare save money by expanding reimbursement for preventive care.
Only one thing is certain: Medicare again will be a big story in 2006.
Focus on Food
2005 New Year's resolutions got a big boost when the U.S. Department of Health and Human Services announced sweeping .
All that got rolled into the U.S. Department of Agriculture's -- the first remodeling of this health landmark in 13 years. It's more than a single pyramid. The new MyPyramid lets you build a food pyramid based on your own health needs. And there's even a new .
8. Katrina and Rita: A One-Two Punch
Few scientific pursuits are more fraught with ethical issues than cloning.
On the one hand, medical researchers hope to clone stem cells, which hold the seemingly magical property of being able to transform into any cell of the body. The cells could be used to repair, replenish, or rejuvenate diseased or worn-out organs -- for example, by replacing .
This kind of cloning, called therapeutic cloning, isn't an ethical slam dunk. While adult stem cells can be cloned, there's still a need to learn from embryonic stem cells. And this raises ethical issues.
For example, Korean researcher Woo Suk Hwang in 2005 reported cloning the first human embryonic stem cells for a specific patient. But some of those cells came from eggs donated by women working as junior scientists in Hwang's lab -- and they were reimbursed $1,445 for "direct expenses." At the time, reimbursing egg donors was not illegal in Korea. As the year ends, is being called into question.
More controversial than therapeutic cloning is reproductive cloning. This means implanting a cloned embryo into the womb of a living female, where it could become a fetus and, eventually, a baby. Scientists are nearly unanimous in rejecting human cloning as unethical. But it's not impossible to achieve. Hwang's Korean lab recently reported the birth of a puppy named Snuppy -- the clone of an Afghan hound named Tai.
Therapeutic cloning isn't the same thing as reproductive cloning. Confusion between the two is a problem, as lawmakers tend to tar therapeutic cloning with the brush of reproductive cloning. Polls show that the therapeutic use of embryonic stem cells.
10. Soda Wars
As the national obesity problem continues to grow, so too does the quest to find a culprit that's causing it. Some of that blame, deserved or not, fell on the shoulder of soft drink manufacturers this year. Lawsuits are in the works to go after "big soda," and one consumer advocacy group labeled soda "liquid candy."
Oddly enough, sweetened soft drinks aren't the only culprit. , too. That's probably because diet drinks are an indicator for other overweight risks -- although animal studies suggest diet drinks may increase appetite.
