Health Tip: Diabetes and Gum Disease

Diabetes can make it more difficult to fight off gum disease, and in some cases, can make gum disease worse.

The American Diabetes Association says you should see if your dentist if you have any of these warning signs of gum disease.

  • Gums that bleed when you floss or brush.
  • Soreness, swelling or redness of the gums, or persistent bad breath.
  • Gums that have receded from the teeth.
  • Pus forming between the teeth and gums.
  • Teeth that seem loose or like you are able to move them.
  • Any change in your bite, or the way that dentures fit.

Health Tip: Eye Health for Diabetics

Fluctuating blood sugar levels can affect diabetics' vision and eye health, so it's important to heed any warning signs of eye problems.

If you're diabetic and have any of these symptoms, the American Diabetes Association says it's time to get them checked by your eye doctor:

  • Blurred or double vision.
  • Pain in one or both eyes.
  • Difficulty reading.
  • Persistent redness of the eyes.
  • Difficulty seeing from the sides of your eyes.
  • A sensation of pressure in one or both eyes.
  • Seeing spots or floaters.
  • If straight lines or objects look crooked.

U.S. Public Health Agency Leaders Being Replaced

The leaders of a number of U.S. government public health agencies are expected to resign or be shown the door as President-elect Obama's team takes control of the White House.

Each of the current public health agency chiefs has severe critics on Capitol Hill and in the public health community, and there have been repeated charges that the Bush administration has let politics play a major role in science policy, The New York Times reported.

On Tuesday, Food and Drug Administration commissioner Dr. Andrew C. von Eschenbach said he would resign on Inauguration Day, Jan. 20. Dr. Elias Zerhouni has already left his position as director of the National Institutes of Health, and it's widely expected that Centers for Disease Control and Prevention director Dr. Julie Gerberding will be replaced by the new administration.

In addition, National Cancer Institute director Dr. John E. Niederhuber is expected to surrender his post, but may remain at the institute, The Times reported.

One leading candidate for the new FDA chief is Dr. Joshua Sharfstein, a pediatrician and health commissioner of Baltimore. Last year, he petitioned the FDA to ban some pediatric over-the-counter cough and cold medicines.

Another short-listed candidate for FDA leader is Dr. Steven E. Nissen, chairman of cardiology at the Cleveland Clinic. He's been a fierce critic of the safety of several big-selling medications.

There's wide agreement among drug companies, drug-safety advocates, and powerful members of Congress that the FDA needs a major overhaul.

"The FDA has increasingly lost its emphasis on public health, and all of us have been harmed as a result," Diana Zuckerman, president of the National Research Center for Women and Families, told the Times.

Illinois Company Faces Lawsuit Over Preemie Heart Drug

Illinois-based Ovation Pharmaceuticals illegally maintained a monopoly on the only two medicines approved to treat a potentially life-threatening heart defect in premature infants, the U.S. Federal Trade Commission alleges in a civil lawsuit filed Tuesday.

The FTC said that after buying the rights to the two medicines (NeoProfen and Indocin) a few years ago, the company boosted the drugs' prices by nearly 1,300 percent. The lawsuit seeks to prevent Ovation from maintaining simultaneous interest in the two drugs and also seeks forfeiture of all unlawfully obtained profits, the Associated Press reported.

Ovation set the price for both medications at about $500. Before it was acquired by Ovation, Indocin cost $36. Each year, the two drugs are used to treat an estimated 30,000 babies with the heart defect called patent ductus arteriousus. The only other option to drug treatment is surgery, which costs far more than the drugs and carries a risk of serious complications.

"As a result, hospitals have little choice but to pay Ovation's price," the FTC said in the lawsuit. "The artificially high prices that hospitals are forced to pay ultimately raise costs for families, tax-supported programs such as Medicaid, and other public and private insurers."

Ovation disputed the FTC's allegations, the AP reported.

Gene Mutation Effects Should Be Listed on Cancer Drug Labels: Lilly, Amgen

Instructions on the cancer drugs Erbitux and Vectibix should include information on a gene mutation that affects whether the medicines will work, drug makers Eli Lilly & Co. and Amgen Inc. told U.S. regulators Tuesday.

Recent research showed that a mutation in the KRAS gene renders the drugs ineffective in colon cancer patients. Overall, the drugs reduced by 30 percent the risk of a patient's colon cancer worsening. However, more detailed analyses showed that patients with KRAS mutations fared much worse than those with a normal KRAS gene, Bloomberg news reported.

An FDA advisory panel met Tuesday to discuss data on the KRAS gene mutation. The advisers said new types of analyses may be required to better screen people for gene mutations, and they also suggested larger clinical trials may be necessary to determine other biochemical influences on drug performance.

"Two companies have come to us to try to create a situation where they sell less products. This is the first time I've seen this at the FDA," said advisory panel member Derek Raghavan, director of the Taussig Cancer Institute at the Cleveland Clinic, Bloomberg reported.

The FDA is currently working to identify genes that interact with medications. The agency already requires patients to undergo genetic testing before they're prescribed certain drugs.

Actor Peter Falk Has Alzheimer's, Daughter Says

Actor Peter Falk, best known as the disheveled TV detective Columbo, whose "Just one more thing" became a household phrase, has developed Alzheimer's disease and no longer recognizes people, according to papers filed in Los Angeles Superior Court, the Associated Press reported.

The papers were filed by the 81-year-old Falk's daughter, Catherine Falk, requesting a conservatorship of his assets. A hearing has been scheduled for late January, the AP said.

People magazine's online edition quoted Catherine Falk's petition as saying that her father "requires full-time custodial care for his health and safety," and that she was worried he could "easily be deceived into transferring away property."

Falk, who has won five Emmys and a Golden Globe award, also has been an Academy Award nominee twice. He lives in Beverly Hills with his wife, actress Shera Danese.

Cleveland Clinic Announces First U.S. Face Transplant

The United States' first almost total face transplant was done a few weeks ago at the Cleveland Clinic, it was announced Tuesday.

About 80 percent of a woman's face was replaced with that of a dead female donor. The procedure was performed by reconstructive surgeon Dr. Maria Siemionow, the Associated Press reported.

The Cleveland Clinic did not release the name or age of the transplant recipient, and has scheduled a news conference for Wednesday.

The world's first face transplant was conducted three years ago on a French woman who'd been mauled by her dog, the AP reported. Since then, two other face transplants have been performed: on a Chinese farmer attacked by a bear, and on a European man disfigured by a genetic condition.

Health Tip: Managing Joint Pain

Joint pain can keep you from exercising, feeling good and performing everyday activities.

It may be triggered by factors including illness, exercise or overuse injury.

The U.S. National Library of Medicine offers general guidelines for how to combat joint pain:

  • Always follow your doctor's treatment plan.
  • When possible, give your joints a rest.
  • Gentle stretching exercises also may help ease joint pain.
  • Take a warm bath, or get a massage.
  • Take an anti-inflammatory drug, but be sure to discuss it with your doctor first, especially if the person with joint pain is a child.

Health Tip: Massage Arthritis Pain

Medication can help ease arthritis pain, but a gentle massage can also provide relief.

The Arthritis Foundation has this advice:

  • If you start to feel pain or discomfort while massaging the arthritic area, stop right away.
  • Avoid massaging any joints that are swollen or very painful.
  • Use lotion or massage oil on your skin.
  • If you massage using a menthol gel, make sure to wash it all off before you apply any heat to the area. This will help prevent burns.
  • If you go to a professional masseuse, make sure he or she has experience in working with people who have arthritis.

Self-Harm Not Limited to Teen Girls: Survey

Self-harm isn't a problem limited to teenage girls, suggests a survey by the British mental health group Sane.

The survey of nearly 1,000 people with a history of self-harm found that more than 10 percent of respondents were male and that some respondents didn't start harming themselves until they were in their 50s, BBC News reported.

About 84 percent said they tried to hide their behavior from their family and 66 percent tried to hide it from friends. Many inflicted damage to a part of their body that was easy to conceal from others or where the injury could be easily explained away as an accident.

Only about 12 percent of respondents said their first act of self-harm was motivated by a desire for attention, and this decreased to about 8 percent for subsequent acts of self-harm, BBC News reported.

The findings show that a wide range of people inflict self-harm, said Marjorie Wallace, chief executive of Sane.

Home-Based Therapy Benefits COPD Patients: Study

For people with chronic obstructive pulmonary disease (COPD), a home-based exercise program is as good as hospital-based rehabilitation, says a Canadian study that included more than 250 patients with the lung disease.

Some of the patients had a one-time training session at home while others had hospital pulmonary training to improve shortness of breath and quality of life. Both programs yielded the same results, CBC News reported.

"Our results prove that home-based rehabilitation is just as effective and safe as that provided in hospitals. What's more, it is a real benefit to patients in comparison to a strictly pharmacological treatment," said study author Dr. Francois Maltais of the Hopital Laval in Quebec.

Along with the economic benefits of home therapy, improvements in patients' physical condition reduced the number of hospital visits, CBC News reported.

The study was published online in the journal Annals of Internal Medicine.

Zimbabwe Cholera Death Toll 978: U.N.

The death toll in Zimbabwe's cholera outbreak now stands at 978, a 25 percent increase over three days ago, according to the United Nations. The UN also said there have been 18,413 suspected cholera cases since the outbreak began in August, BBC News reported.

The worst-hit area is the capital Harare, with 208 confirmed deaths and 8,454 suspected cases, said the UN's Office for the Co-ordination of Humanitarian Affairs, which estimated that up to 60,000 people in the country may eventually be affected by the disease.

The cholera outbreak has spread quickly in Zimbabwe due to serious problems with the health care and water systems. The South African Red Cross has sent a truckload of medical supplies to treat cholera patients and has issued an urgent appeal to fund supplies to treat a total of 30,000 people, BBC News reported.

Last week, Zimbabwe President Robert Mugabe said the cholera outbreak had been halted.

Health Tip: Where to Keep a Fire Extinguisher

Smoke detectors aren't the only way to prevent a fire-related disaster at home. You should also have at least one fire extinguisher available, the U.S. National Safety Council says.

An all-purpose extinguisher (one that combats both grease and electrical fires) should always be kept in the kitchen. You should also keep one in the garage, near your furnace, and anywhere else where something combustible could start a fire.

Fire extinguishers, however, won't help if no one in the home knows how to use them. Every able-bodied person in the home should be familiar with how to use fire extinguishers, and where they are kept.

Health Tip: Using a Carbon Monoxide Detector

If you have a carbon monoxide detector in your home, you also need to be prepared with an action plan in case the alarm sounds.

The National Safety Council offers these suggestions if there may be a carbon monoxide leak in your home:

  • Quickly confirm that the alarm is coming from a carbon monoxide detector -- not a smoke detector.
  • Make sure that everyone in the house is feeling OK, without any symptoms. These may include fatigue, headache, weakness, confusion, disorientation, nausea or dizziness.
  • Anyone experiencing symptoms should be immediately taken out of the house to get medical attention.
  • If everyone is OK, open up the windows in your home and turn off any boiler, furnace, chimney or appliance that could release carbon monoxide.
  • Have a technician inspect all potential sources of carbon monoxide -- including appliances and chimneys that burn fuel -- to make sure they are working properly.

Behavioral Therapy Helps Eating Disorder Patients: Study

Specially designed cognitive behavioral therapy can help many people with eating disorders, according to a British study that included 154 patients.

The outpatient counseling sessions strive to help patients understand the links between their emotions and behavior in order to make changes. The patients had one 50-minute session per week for 20 weeks, BBC News reported.

Two-thirds of the patients achieved a "complete and lasting" response to the therapy, while the other third showed substantial improvement. The findings were published in the American Journal of Psychiatry.

"Now, for the first time, we have a single treatment which can be effective at treating the majority of cases, without the need for patients to be admitted into hospital," said study leader Professor Christopher Fairburn, of the University of Oxford, BBC News reported.

The study included bulimia and "atypical" patients, but did not include anorexia patients. A second study involving anorexia patients is under way and is showing promising results, the researchers said.

Brushing Teeth Reduces Patients' Pneumonia Risk

Brushing intubated hospital patients' teeth three times a day reduces their risk of pneumonia by 50 percent, according to an Israeli study scheduled for publication in a nursing journal.

"Pneumonia is a big problem in hospitals everywhere, even in the developed world," said researcher Ofra Raanan, of the Sheba Academic School of Nursing at the Chaim Sheba Medical Center, United Press International reported.

"Patients who are intubated can be contaminated with pnemonia only two to three days after the tube is put in place. But pneumonia can be effectively prevented if the right measures are taken," Raanan said.

Salt-Cured Alewives Pose Botulism Risk: FDA

Ungutted salt-cured alewives (also known as gaspereaux fish) produced by a Canadian firm and sent to distributors in Florida shouldn't be eaten because they may contain the bacterium that causes botulism, the U.S. Food and Drug Administration said.

The fish produced by Michel and Charles LeBlanc Fisheries Ltd. of New Brunswick may be tainted with Clostridium botulinum. This toxin can cause botulism, a potentially life-threatening condition that can't be prevented by cooking or freezing, the FDA said in a news release.

The fish were imported to the following Florida distributors: Quirch Foods Inc., Den-Mar Exports LLC, Dolphin Fisheries Inc., and Labrador and Son Food Products Inc.

The products were distributed in 173 white plastic 30-pound pails with green lids. The fish may have been repackaged for individual sale, the agency said.

There have been no reports of illness associated with this product. But the FDA warned that Florida-bought ungutted alewives produced by this manufacturer, or such fish of undetermined origin, should be thrown away immediately.

Symptoms of botulism can begin six hours to 10 days after consumption, and may include double- or blurred vision, drooped eyelids, slurred speech, difficulty swallowing, dry mouth, and muscle weakness. Botulism can also cause deadly paralysis of the breathing muscles. Anyone with these symptoms should be given immediate medical attention.

Health Tip: Braces Basics

Braces require special care to help keep them functioning properly and prevent tooth damage.

The American Association of Orthodontists offers these suggestions for taking care of your teeth and braces:

  • Brush and floss your teeth each day. Infrequent brushing can lead to more trips to the dentist or orthodontist.
  • The cleaner and healthier teeth are, the faster they will move, the AAO says.
  • If you play a sport, you may need to wear a mouth guard.
  • Never chew on pens, pencils, erasers or fingernails.
  • Stay away from foods that are very hard or crunchy, sticky or chewy.

Health Tip: Heading Out on Vacation?

Before you hit the road for an extended vacation, don't forget to pack a medical supply kit.

The Cleveland Clinic offers these suggestions for what to include:

  • Sterile pads, bandages and cotton, as well as an antiseptic.
  • Scissors, tweezers, thermometer and antibacterial wash.
  • Basic over-the-counter products, such as a pain reliever, decongestant and motion-sickness medication.
  • Sunscreen and bug spray.
  • Anti-diarrhea medication and an antacid.
  • Toilet paper and a clean washcloth.
  • If you're going to a warm climate, pack some salt tablets to help prevent excess sweating.

Dueling U.S. Agencies at Odds Over Fish Consumption

A proposal to encourage eating of fish to promote a healthier lifestyle is becoming a political issue in the final months of the Bush administration, reports the Associated Press.

A long-standing government recommendation that pregnant women and children limit their intake of fish because of the possibility that they may also consume harmful amounts of mercury is being reconsidered by the U.S. Food and Drug Administration, the wire service reports.

This has evoked intra-agency controversy, with the Environmental Protection Agency challenging the scientific accuracy of the FDA's 270 page draft of a study concluding that the health benefits of fish consumption outweigh the possibility that a dangerous amount of mercury would be ingested.

Environmental groups are upset as well, the AP reports. Richard Wiles, executive director of the Environmental Working Group, issued a statement: "The FDA was once a fearsome protector of the public health. Now it's nothing more than a patsy for polluters."

Not surprisingly, the food industry is supportive of the FDA's study. One lobbying group, the Center for Consumer Freedom, told the wire service that it "just might be the best Christmas present health-conscious Americans could hope for."

Test Predicts Onset of Preterm Labor

A test that predicts whether premature birth is imminent if a woman's water breaks early in pregnancy has been identified by Swedish researchers.

In such cases, there's a strong link between high levels of lactate in vaginal fluid and onset of labor within 48 hours, said the researchers, who assessed the test in 86 women with single pregnancies of 20 to 36 weeks gestation, BBC News reported.

The study found that 87 percent of the 23 women with high lactate concentrations had spontaneous labor within 48 hours, compared with 5 percent of the 58 women with low lactate concentrations.

Among women with high lactate concentrations, the average time between examination of labor onset was 13.6 hours, compared with 48 days for those with low lactate levels, BBC News reported.

The study about the "Lac-test" appears in BJOG: An International Journal of Obstetrics & Gynaecology.

FDA Panel Endorses New Female Condom

A second-generation female condom called the FC2 Female Condom should be approved for use in the United States, a Food and Drug Administration advisory panel decided Thursday.

In its 15-0 vote recommending approval by the full agency, the panel said there should be a condition that instructions for use remain the same as those for the FC1 Female Condom. The panel also said the manufacturer should identify the study performed to establish the comparable safety and effectiveness of FC2 with FC1.

The first generation FC1 condom was approved for U.S. sale in 1993, and 165 million of the condoms have been distributed in 142 countries. So far, 22 million of the FC2 condoms have been distributed in 77 countries. The World Health Organization has said the condoms can be purchased by United Nations agencies.

The FC2 condom looks similar to the FC1, but is produced and sold at a lower cost. The product is made by the Female Health Company, based in Chicago.

While not required to do so, the FDA usually follows the advice of its advisory panels.

Certain Dementia Patients Can't Detect Sarcasm

People under the age of 65 with frontotemporal dementia (FTD) can't detect when someone is being sarcastic, a finding that may help improve diagnosis of the condition, say Australian researchers.

FTD, also called Pick's disease, is the second most common form of dementia and can be difficult to diagnose in its early stages.

In this study, actors presented scenarios to 26 FTD patients and 19 Alzheimer's patients. The scenarios used the exact same words but were presented either in a sincere tone or laced with sarcasm, Agence France Presse reported.

The Alzheimer's patients picked up on the sarcasm but the FTD patients did not, concluded the University of New South Wales study, which appears in the journal Brain.

"The patients with FTD are very literal and they take what is being said as genuine and sincere," AFP quoted senior author John Hodges as saying. He said the findings help explain the behavior of people with FTD, which is often upsetting to family members.

"(FTD patients) find it difficult to interact with people, they don't pick up on social cues, they lack empathy, they make bad judgments," Hodges said.

Health Tip: Driving During Winter

Depending on where you are, winter can herald a greater risk of car accident, a car that won't start, and getting stranded in wintry conditions.

The U.S. National Safety Council offers these suggestions for safe winter driving:

  • Get your car properly tuned up, and make sure the tires are in good shape before winter starts.
  • Carry equipment in your car, including a tire jack, spare tire, jumper cables, chains, salt or cat litter, flashlight and batteries, and a tool kit.
  • In your car, store non-perishable foods such as unsalted nuts, dried fruits and hard candies.
  • Especially on a long winter trip, pack necessities to keep you warm -- a warm blanket, socks, a hat and gloves.
  • Keep a first aid kit in your car at all times.

Health Tip: Stay Awake Behind the Wheel

People who work the third shift, drive great distances each day, and those who don't get enough sleep or take sedating medications are at greatest risk of drowsy driving.

But everyone is at risk of being impaired behind the wheel because they're too tired. The National Safety Council offers these suggestions to prevent drowsy driving:

  • Get plenty of sleep before you head out on the road.
  • If you start to feel tired, go to a safe area for a quick rest. But don't pull over at the side of the road.
  • Try not to drive between the hours of 12 a.m. and 6 a.m.
  • For long trips, start driving early in the morning, and plan to switch off driving with a buddy.
  • Keep the temperature inside the car cool and comfortable.
  • Take a quick break every 100 miles or so to have a snack, get some fresh air or just to stretch your legs.

Obama Announces Daschle Is HHS Secretary Nominee

President-elect Barack Obama formally introduced former Senate Majority Leader Tom Daschle Thursday as his nominee for U.S. Health and Human Services secretary, according to published reports.

Calling America's health care system the nation's "largest domestic policy challenge," Obama also said Daschle would oversee a new White House Office of Health Reform.

Obama's choice of Daschle to head HHS has been known for several weeks.

Daschle, a Democrat who was part of the health care advisory group of Obama's transition team, has said he was excited about the possibility of leading the new president's efforts to change the nation's health care system.

He believes reforming health care is a priority in the current economic downturn.

"We can't afford not to do it. If we do nothing, we'll be paying twice as much on health care in 10 years as we do today," he said last month, CNN reported.

In a recent book titled Critical: What We Can Do About the Health Care Crisis, Daschle advocated universal health coverage to reach 46 million uninsured people. He said this could be done by expanding the federal employee health benefits program to include private employer plans together with Medicare and Medicaid.

Jeanne Lambrew, who helped Daschle write the book about health care reform, will serve as deputy director of the new White House health policy office. Heads of health advocacy groups have described Lambrew as one of Daschle's most trusted advisers on health issues. She will oversee planning efforts, the AP reported.

Hong Kong Reports First Farm Outbreak of Bird Flu in 6 Years

The first outbreak of H5N1 bird flu on a Hong Kong poultry farm in nearly six years was confirmed by government officials Thursday.

It was announced Tuesday that bird flu was found on a farm near the Chinese border and 90,000 chickens were scheduled for slaughter by the end of the week. Initial tests identified an H5 virus and the new test results confirmed that it's the deadly H5N1 virus, Agence France Presse reported.

The virus has not been found on any other farms in the area.

The World Health Organization is monitoring the situation, said Peter Cordingley, a spokesman for the WHO's Western Pacific regional office. He told AFP the outbreak isn't a surprise because the virus is versatile and tends to be more active in winter.

Hong Kong officials said the H5N1 virus has "changed slightly" and have told scientists to investigate whether the vaccine used since 2003 to protect chickens against bird flu is still effective.

Health Tip: Maintain a Healthy Lifestyle

No one knows precisely why people get cancer, and there's no surefire cure.

But if you maintain a healthy lifestyle, you can help reduce your risk. Here are some suggestions, courtesy of AARP:

  • Eat a healthy diet, including plenty of whole grains, fruits and vegetables. Limit intake of red meat, saturated fats, smoked and salt-cured foods, and foods preserved with nitrates.
  • Get regular exercise of 30 minutes or more at least five days a week.
  • Maintain a healthy body weight.
  • If you drink alcohol, do so in moderation.
  • Wear sunscreen and avoid prolonged exposure to direct sun during the midday hours.
  • Get screened for cancers for which you may be most susceptible.
Health Tip: Get Screened for Cancer

Early detection, by way of regular screening, is one of the best ways to beat cancer.

The American Cancer Society offers these guidelines for cancer screenings:

  • Women, starting at age 40, should get an annual mammogram to screen for breast cancer. Breast exams should start at age 20. An annual exam is recommended at age 40. Before that, women at normal risk should be examined about every three years.
  • Beginning at age 50, women and men need regular screening for colorectal cancer. People at an increased risk for colorectal cancer should be tested earlier.
  • Women need regular Pap smears to screen for cervical cancer. Pap smears should be given within three years of starting intercourse, or by age 21, whichever is earlier.
  • Men 50 and older should get the prostate-specific antigen (PSA) test and a digital rectal examination annually. Men at higher risk should begin testing at age 45.

Test Predicts Onset of Preterm Labor

A test that predicts whether premature birth is imminent if a woman's water breaks early in pregnancy has been identified by Swedish researchers.

In such cases, there's a strong link between high levels of lactate in vaginal fluid and onset of labor within 48 hours, said the researchers, who assessed the test in 86 women with single pregnancies of 20 to 36 weeks gestation, BBC News reported.

The study found that 87 percent of the 23 women with high lactate concentrations had spontaneous labor within 48 hours, compared with 5 percent of the 58 women with low lactate concentrations.

Among women with high lactate concentrations, the average time between examination of labor onset was 13.6 hours, compared with 48 days for those with low lactate levels, BBC News reported.

The study about the "Lac-test" appears in BJOG: An International Journal of Obstetrics & Gynaecology.

FDA Panel Endorses New Female Condom

A second-generation female condom called the FC2 Female Condom should be approved for use in the United States, a Food and Drug Administration advisory panel decided Thursday.

In its 15-0 vote recommending approval by the full agency, the panel said there should be a condition that instructions for use remain the same as those for the FC1 Female Condom. The panel also said the manufacturer should identify the study performed to establish the comparable safety and effectiveness of FC2 with FC1.

The first generation FC1 condom was approved for U.S. sale in 1993, and 165 million of the condoms have been distributed in 142 countries. So far, 22 million of the FC2 condoms have been distributed in 77 countries. The World Health Organization has said the condoms can be purchased by United Nations agencies.

The FC2 condom looks similar to the FC1, but is produced and sold at a lower cost. The product is made by the Female Health Company, based in Chicago.

While not required to do so, the FDA usually follows the advice of its advisory panels.

Certain Dementia Patients Can't Detect Sarcasm

People under the age of 65 with frontotemporal dementia (FTD) can't detect when someone is being sarcastic, a finding that may help improve diagnosis of the condition, say Australian researchers.

FTD, also called Pick's disease, is the second most common form of dementia and can be difficult to diagnose in its early stages.

In this study, actors presented scenarios to 26 FTD patients and 19 Alzheimer's patients. The scenarios used the exact same words but were presented either in a sincere tone or laced with sarcasm, Agence France Presse reported.

The Alzheimer's patients picked up on the sarcasm but the FTD patients did not, concluded the University of New South Wales study, which appears in the journal Brain.

"The patients with FTD are very literal and they take what is being said as genuine and sincere," AFP quoted senior author John Hodges as saying. He said the findings help explain the behavior of people with FTD, which is often upsetting to family members.

"(FTD patients) find it difficult to interact with people, they don't pick up on social cues, they lack empathy, they make bad judgments," Hodges said.

Obama Announces Daschle Is HHS Secretary Nominee

President-elect Barack Obama formally introduced former Senate Majority Leader Tom Daschle Thursday as his nominee for U.S. Health and Human Services secretary, according to published reports.

Calling America's health care system the nation's "largest domestic policy challenge," Obama also said Daschle would oversee a new White House Office of Health Reform.

Obama's choice of Daschle to head HHS has been known for several weeks.

Daschle, a Democrat who was part of the health care advisory group of Obama's transition team, has said he was excited about the possibility of leading the new president's efforts to change the nation's health care system.

He believes reforming health care is a priority in the current economic downturn.

"We can't afford not to do it. If we do nothing, we'll be paying twice as much on health care in 10 years as we do today," he said last month, CNN reported.

In a recent book titled Critical: What We Can Do About the Health Care Crisis, Daschle advocated universal health coverage to reach 46 million uninsured people. He said this could be done by expanding the federal employee health benefits program to include private employer plans together with Medicare and Medicaid.

Jeanne Lambrew, who helped Daschle write the book about health care reform, will serve as deputy director of the new White House health policy office. Heads of health advocacy groups have described Lambrew as one of Daschle's most trusted advisers on health issues. She will oversee planning efforts, the AP reported.

Hong Kong Reports First Farm Outbreak of Bird Flu in 6 Years

The first outbreak of H5N1 bird flu on a Hong Kong poultry farm in nearly six years was confirmed by government officials Thursday.

It was announced Tuesday that bird flu was found on a farm near the Chinese border and 90,000 chickens were scheduled for slaughter by the end of the week. Initial tests identified an H5 virus and the new test results confirmed that it's the deadly H5N1 virus, Agence France Presse reported.

The virus has not been found on any other farms in the area.

The World Health Organization is monitoring the situation, said Peter Cordingley, a spokesman for the WHO's Western Pacific regional office. He told AFP the outbreak isn't a surprise because the virus is versatile and tends to be more active in winter.

Hong Kong officials said the H5N1 virus has "changed slightly" and have told scientists to investigate whether the vaccine used since 2003 to protect chickens against bird flu is still effective.

Health Tip: Be Cautious at Christmas

Holiday decorations, including trees and lights, should be properly set up and maintained to keep your home merry and safe.

The National Safety Council offers these suggestions:

  • Never burn evergreen branches or wreaths in an indoor fireplace, as they can cause large flames.
  • Be careful where you place lit candles. Keep them away from trees and other decorations.
  • If you have young children, avoid putting decorative plants around the home. Many plants, including mistletoe, holly berries, Jerusalem cherry and amaryllis, are dangerous if swallowed.
  • Be careful when spraying decorations with artificial snow. Doing so makes them more flammable.

Health Tip: Using a Carbon Monoxide Detector

If you have a carbon monoxide detector in your home, you also need to be prepared with an action plan in case the alarm sounds.

The National Safety Council offers these suggestions if there may be a carbon monoxide leak in your home:

  • Quickly confirm that the alarm is coming from a carbon monoxide detector -- not a smoke detector.
  • Make sure that everyone in the house is feeling OK, without any symptoms. These may include fatigue, headache, weakness, confusion, disorientation, nausea or dizziness.
  • Anyone experiencing symptoms should be immediately taken out of the house to get medical attention.
  • If everyone is OK, open up the windows in your home and turn off any boiler, furnace, chimney or appliance that could release carbon monoxide.
  • Have a technician inspect all potential sources of carbon monoxide -- including appliances and chimneys that burn fuel -- to make sure they are working properly.

Men's Genes Influence Offsprings' Gender

A man's genes may play a major role in whether he has sons or daughters, according to U.K. researchers who examined 927 family trees that included information on 556,387 people from Europe and North America.

The study found that men were more likely to have sons if they had more brothers and more likely to have daughters if they had more sisters, BBC News reported. The same link between sibling gender and offspring gender wasn't seen in women.

The results provide strong evidence of a genetic component affecting the relative numbers of "X" and "Y" sperm produced by men, said study author Dr. Corry Gellatly, who added that this type of male-directed gender selection balances out the proportion of men and women in the population.

"If there are too many males in the population, for example, females will more easily find a mate, so men who have more daughters will pass on more of their genes, causing more females to be born in later generations," Gellatly said, BBC News reported.

The study was published in the journal Evolutionary Biology.

Doctors Call for Human Studies of New Defibrillators

Human studies must be conducted before important new technology is used in heart defibrillators, say two prominent heart doctors who helped shed light on previous medical device defects.

The new "four-pole connector" technology is a more compact way of connecting heart defibrillators to wires -- called leads -- that conduct electricity to the heart. It would allow defibrillators to be smaller and leads thinner, which would make the implant procedure easier, the Wall Street Journal reported.

The U.S. Food and Drug Administration plans to allow defibrillator makers to sell the new implantable cardioverter defibrillators (ICDs) without conducting human studies, something that "is not in the best interest of patients," cardiologists Dr. Robert G. Hauser and Dr. Adrian K. Almquist wrote in this week's New England Journal of Medicine.

The Minneapolis Heart Institute doctors said they're concerned the new technology could be prone to potentially deadly short-circuiting, the Wall Street Journal reported.

The FDA disputed the cardiologists' claim that the agency has decided to allow the new devices to be sold without human testing, the newspaper said.

Health Tip: When a Loved One Has Cancer

If you have a family member or friend who has been diagnosed with cancer, you may be puzzled about how you can help.

The American Cancer Society offers these suggestions:

  • Prepare meals to keep on hand, or deliver meals each day at certain times, so the person doesn't have to worry about what to eat.
  • Help out with the kids by driving them to and from school, practices and other activities.
  • Drive the loved one to and from doctor appointments.
  • Fill in for him or her when not feeling well. Run errands, take care of chores, or just answer the phone.
  • Research the disease so you can discuss what the person is going through.

Health Tip: Get Screened for Cancer

Early detection, by way of regular screening, is one of the best ways to beat cancer.

Zimbabwe Cholera Epidemic Continues to Spread

The cholera epidemic in Zimbabwe is spreading rapidly, with a reported 15,572 cases and 746 deaths, the United Nations said Wednesday.

A deteriorating health care system and water infrastructure are the reasons why the water-borne disease is rampaging through the impoverished African nation, which last week declared a health emergency, the Associated Press reported.

Aid agencies say coming rains could further spread the disease in a population already weakened by disease and hunger.

There are also concerns that cholera could be carried into neighboring countries. A large number of Zimbabweans with cholera have sought help in South Africa, which has reported 500 cases of the disease, including nine deaths, the AP reported.

Cutbacks Affecting U.S. Health Preparedness: Report

Previous progress made in preparing to deal with disease outbreaks, natural disasters and bioterrorism in the United States is being threatened by the economic crisis and budget cuts, a new report contends.

The sixth annual "Ready or Not?" report, released Tuesday by Trust for America's Health and the Robert Wood Johnson Foundation, also found that major gaps remain in many critical areas of emergency preparedness, including food safety and rapid disease detection, MarketWatch reported.

Ten key indicators were used to score states on their health preparedness. More than half of the states and the District of Columbia achieved no more than seven out of the 10 indicators. Louisiana, New Hampshire, North Carolina, Virginia and Wisconsin scored 10 out of 10, while Arizona, Connecticut, Florida, Maryland, Montana and Nebraska tied for lowest, 5 out of 10.

The United States' food safety system hasn't been fundamentally modernized in more than 100 years, the report said. Twenty states and D.C. didn't meet or exceed the national average rate for being able to identify pathogens responsible for food-borne disease outbreaks in their states, MarketWatch reported.

Twenty-four states and D.C. don't have the capacity to deliver and receive lab specimens, such as suspected bioterror agents or new disease outbreak samples, on a 24/7 basis, the report added.

Recession Putting Burden on Emergency Departments

An increasing number of unemployed and uninsured Americans are seeking treatment in hospital emergency departments, causing overcrowding that could make it difficult for the centers to handle such medical emergencies as heart attacks and trauma injuries, according to an American College of Emergency Physicians report released Tuesday.

Even before the recession, overcrowding in many U.S. emergency departments meant long patient waits and the frequent need to redirect ambulances to other hospitals, The New York Times reported.

"We have no capacity now. There's no way we have room for any more people to come to the table," said Dr. Angela F. Gardner, president-elect of the ACEP, who added that any public dialogue about overhauling the current health system has to include emergency departments.

The unemployed and uninsured are resorting to emergency departments because the departments must see all patients who enter their doors, regardless of ability to pay. But emergency departments are also seeing insured patients who don't have quick access to regular doctors, the Times reported.

High-Fructose Corn Syrup Not Cause of Obesity Epidemic: Studies

There's no link between increased consumption of high-fructose corn syrup and the obesity epidemic in the United States, according to five studies published this week in a supplement to the journal Clinical Nutrition.

For a number of years, high-fructose corn syrup (a liquid sweetener widely used in food and drinks) has been regarded as a major reason for the growing number of overweight Americans. But these new studies say that's not the case, USA Today reported.

"It doesn't appear that when you consume high-fructose corn syrup, you have any different total effect on appetite than if you consume any other sugar," said Barry Hopkins, the author of one of the studies.

High-fructose corn syrup accounts for about 50 percent of the sweeteners used in the United States and about 10 percent of sweeteners used worldwide, said John White, the author of another of the studies.

"But obesity isn't just a U.S. problem," he noted, USA Today reported.

Health Tip: Having Sex Despite Illness

People who have a chronic illness -- which may include heart disease, diabetes or asthma -- may have ongoing pain or fatigue that can hinder a healthy sex life.

The American Academy of Family Physicians offers suggestions for how to enjoy sex, despite having a chronic illness:

  • Figure out what time of day you feel healthiest and most energized, and plan sex around those times.
  • Try to get plenty of rest, and make yourself feel as relaxed as possible.
  • Don't have sex within two hours of eating.
  • If you take pain medicine, take it at least 30 minutes before having sex.
  • Drink only limited amounts of alcohol, and don't use tobacco. Both can affect sexual performance.

Health Tip: Sex During Pregnancy

While sexual intercourse throughout a healthy pregnancy is usually safe, it may not be recommended for women who are a higher risk for complications.

The Nemours Foundation says sex may not be safe for pregnant women with any of the following risk factors:

  • A history or risk of miscarriage.
  • Having had a previous birth that was pre-term (earlier than 37 weeks), or having warning signs of pre-term labor.
  • Vaginal bleeding, discharge or cramping that cannot be diagnosed.
  • Leaking amniotic fluid.
  • Conditions such as placenta previa and incompetent cervix.
  • Carrying multiple fetuses.

Diesel Truckers Have Higher Lung Cancer Risk: Report

Diesel truck drivers are more likely to develop lung cancer than other workers, according to U.S. researchers who examined the records of 31,135 workers, the San Francisco Chronicle reported.

Short-haul drivers had a greater risk than long-haul drivers. This may be because long-haul drivers often keep their windows closed while short-haul drivers keep their windows open and have greater exposure to diesel exhaust, said the researchers from Harvard Medical School and the University of California, Berkeley School of Public Health.

Fresh, newly released diesel particles have a greater potential to cause DNA mutations that lead to lung cancer, according to the study, published in the journal Environmental Health Perspectives.

The study findings will be considered by California's Air Resources Board when it meets Friday to vote on a new regulation to reduce the public health threat posed by diesel truck exhaust, the Chronicle reported.

If the rule is adopted, California would become the first state to require a retrofit or replacement of every privately owned older, heavy-duty diesel truck on the road, the newspaper said.

Pistol Not a Medical Device: FDA

A single-bullet pistol designed to be used as protection by seniors and the disabled will not be approved as a medical device and won't be covered by Medicare, the U.S. Food and Drug Administration said Monday.

The oval-shaped Palm Pistol fits in a person's palm and the barrel sticks out through the fingers. Instead of a trigger, the gun is fired by a thumb- activated button, the Associated Press reported.

The inventor, Matthew M. Carmel of Maplewood, N.J., said an FDA representative advised him to register his company as a medical device facility and list the Palm Pistol as a "recreational adaptor." The registration seemed to go smoothly, but was revoked Monday by the FDA.

Carmel got some bad advice from that agency person, FDA spokeswoman Siobhan DeLancey told the AP.

Health Tip: Symptoms of a Social Phobia

A social phobia occurs when a person has unusually high anxiety before a social situation, such as going to a party, giving a speech, or going to a job interview.

It may include some or all of these physical symptoms, says the American Academy of Family Physicians:

  • Blushing.
  • Sweating.
  • Feeling nauseous.
  • Trembling or shaking.
  • Having trouble talking to or making eye contact with another person.

If you have these symptoms, a doctor should evaluate you for a social phobia. The physician can also recommend treatment options, including medication and/or behavioral therapy.

Health Tip: Prepare Yourself for Surgery

In the days before surgery, it's important to make sure that you are physically healthy, and that your mind is relaxed and prepared.

Here are suggestions from the National Women's Health Resource Center on what to do before your operation:

  • Maintain a healthy, balanced diet. Be sure to get enough vitamin C, which will help your body heal.
  • Quit smoking and avoid alcohol.
  • Get regular exercise.
  • Don't use blood-thinning medications, including aspirin, for one week before surgery. If you have a need to take such medications, discuss this with your doctor.
  • Keep a positive attitude.
  • Talk to your doctor about how to control post-surgical pain.
  • Try deep breathing techniques and relaxation exercises.

Irish Pork May Contain Cancer-Causing Chemicals

Irish pork that may be tainted with cancer-causing dioxins has been removed from sale in Europe and Asia.

The Irish government ordered all pig meat products made since Sept. 1 to be withdrawn after dioxins were found in slaughtered pigs believed to have eaten tainted feed, Agence France Presse reported.

Authorities are investigating a feed company suspected of being linked to the contamination and up to 100,000 pigs from affected farms will be slaughtered.

Contaminated meat may have been shipped to 12 European Union countries and nine nations outside of Europe, AFP reported. Japan, Singapore and South Korea have suspended imports of Irish pork products.

Commentary Supports Brain Stimulant Pills

In a controversial commentary article, a group of experts argues that healthy people should be able to use stimulants to give their brains a boost. They said using pills to increase brain function is no more morally objectionable than eating right or getting a good night's sleep.

The commentary in the journal Nature calls for more research into this area and steps to manage any risks, the Associated Press reported.

"I would be the first in line if safe and effective drugs were developed that trumped caffeine," article co-author Michael Gazzaniga, of the University of California, Santa Barbara, said in a an e-mail.

While some health experts agreed this is an area that deserves attention, Leigh Turner of the University of Minnesota Center for Bioethics disagreed.

"It's a nice puff piece for selling medications for people who don't have an illness of any kind," Turner told the AP.

Cold Sore Virus Linked to Alzheimer's

People who develop cold sores may be at increased risk for Alzheimer's disease, according to British researchers who said the herpes virus that causes cold sores is a major cause of the brain protein plaques associated with Alzheimer's.

The University of Manchester team found DNA evidence of the herpes simplex virus (HSV) type 1 in 90 percent of plaques in Alzheimer's patients' brains, BBC News reported. The findings were published in the Journal of Pathology.

"We suggest that HSV1 enters the brain in the elderly as their immune systems decline and then establishes a dormant infection from which it is repeatedly activated by events such as stress, immunosuppression, and various infections," said Professor Ruth Itzhaki.

This causes damage to brain cells, which die and disintegrate, releasing the proteins that form the plaques that cause Alzheimer's, the study suggested.

The potential good news in this study is that antiviral drugs used to treat cold sores may also prevent dementia. Itzhaki and colleagues plan to test that theory, BBC News reported.

Body Clock Gene Fault Linked to Diabetes

Faults in an important body clock gene (MTNR1B) are associated with higher blood sugar levels and increased risk of type 2 diabetes, according to international teams of researchers.

MTNR1B helps control the action of the hormone melatonin on different parts of the body. Melatonin plays a role in drowsiness and the lowering of body temperature.

The researchers, who analyzed the genomes of thousands of people, said their findings could lead to new ways to control or prevent diabetes, BBC News reported.

"Our research demonstrates that abnormalities in the circadian rhythm may partly be causing diabetes and high blood sugar levels -- we hope it will ultimately provide new options for treating people," said Professor Philippe Froguel of Imperial College London.

The findings appear in the current issue of the journal Nature Genetics.
