Some Noticing Antiviral Medicine Shortage

PICKERINGTON, Ohio — Some central Ohio pharmacies are dealing with shortages of antiviral medication, like Tamiflu, as more people are treated for flu-like symptoms, 10TV's Kevin Landers reported on Sunday.

Dr. Lee Bowman with America's Urgent Care said many patients with flu symptoms are being treated as if they have H1N1.

That has put a strain on some pharmacies that are trying to keep up with demand.

SPECIAL SECTION: H1N1

"Occasionally we'll get a call back from a patient that we've written a prescription for Tamiflu or Relenza, (and) they'll call back and tell me that the pharmacy doesn't have it," Bowman said.

Antiviral medication is not a cure for the flu, but doctors said it can offer some relief from the symptoms.

"It does help alleviate the symptoms of the flu and it does have some antiviral properties to help kill off some of the virus," Bowman said.

The Centers for Disease Control and Prevention said certain people should not take antiviral medicine, including children younger than 2 and adults 65 and older.

Pregnant women and people with certain chronic medical conditions like asthma, heart failure and lung disease should refrain from taking antiviral medication.

Fresh Ways to Burn More Calories

woman on a swing
Jump in the water, hop on a swing, or run with a hound to burn more calories this summer—sans gym membership.

by Bethany Lye

From hula-hooping to picking berries, we’ve got 18 surprising ways to rev up your heart rate and help you slim down.

Boosting your heart rate keeps your heart in top form and burns serious calories—no gym membership required. Here are 18 simple, surprising tips to help you get your heart pumping this summer.

1. Move your workout into the water. The next time you’re at the beach or poolside, take a break from lounge-chair languishing and try a shallow-water workout instead. Walking through thigh-deep water burns nearly twice as many calories as walking on land.
Total burn: More than 210 calories per half-hour

2. Hold the ’07 Olympic trials in your backyard. The real Games may be a year off, but you can make your mark in the garden-rock shot put or sandbox long jump. Choose your favorite summer Olympic sport and tweak it to make it backyard-friendly. Then gather all the friends and family you can and go for the gold.
Total burn: 170 calories per half-hour

3. Adopt a stretch of park or beach and keep it clean. Picking up trash can help both your community and your heart. Start by recruiting buddies, then crank up some fast-paced tunes on your boom box or MP3 player and get to work. All that squatting and lunging will leave you—and the land—looking beautiful.
Total burn: 102 calories per half-hour

4. Take a bike tour of a nearby city. Explore new neighborhoods, or grab a friend and a map to create your own sightseeing trip. Your heart will be racing in no time.
Total burn: Around 270 calories per half-hour at a moderate pace

5. Pick your own berries. Get a full-body workout while you gather fresh fruit. Walk the fields at a nearby farm, pick to your heart’s content, then carry the berry-filled baskets back to your car. To find a local farm, visit pickyourown.org.
Total burn: 102 calories per half-hour

6. “Test out” playground equipment. 170 calories per half-hour

7. Crank up the iPod and get your groove on. 153 calories per half-hour

8. Go canoeing. 119 calories per half-hour

9. Scale the longest staircase in town. 272 calories per half-hour

10. Get spinning with a hula hoop. 153 calories per half-hour

11. Jog on the beach. 238 calories per half-hour

12. Twirl a jump rope. 340 calories per half-hour

13. Play a game of tennis—with no out-of-bounds. 238 calories per half-hour

14. Volunteer to walk dogs at a local shelter. 102 calories per half-hour

15. Take a self-defense class. 340 calories per half-hour

16. Listen to books on tape while walking the chapters away. 129 calories per half-hour

17. Cultivate a garden of your family’s favorite veggies. 136 calories per half-hour

18. Pack a picnic and hike to the perfect spot. 238 calories per half-hour

Note: All calorie estimates are based on a 150-pound woman.

Can't remember? Sleep on it

Throw out the ginkgo. Forget mnemonics. New research suggests there's a simple way to lock in new info: Sleep on it.

Researchers at Harvard Medical School in Boston asked 48 subjects to learn a list of 20 pairs of words and then tested them 12 hours later on their recall of the pairs. Some subjects were taught the words at 9 a.m., while others learned the words at 9 p.m. and then went to sleep.

The results, to be reported this week at a neurology meeting, were a wake-up call for all-night exam crammers: Subjects in the sleep group remembered 12 percent more words from the list than subjects who learned the words at 9 a.m.

Half of both groups also were asked to learn a second list of words just before testing, to study the effect of distracting information on recall. Yet again, subjects in the sleep group did better, recalling 44 percent more words than subjects in the nonsleep group.

Lead author and neurologist Dr. Jeffrey Ellenbogen said he believes the memory boost could be caused by the brain replaying daytime information during sleep, similar to a rehearsal. And he has some advice for sleep-deprived students.

"I tell my students that you might do OK if you cram for an exam all night long, but don't expect that memory to last very long,'' he says in an e-mail. "Sleep is important for making memories stable and strong.''

When Bad Hair Happens to Good People

Bad Haircut

When Bad Hair Happens to Good People

by Caitlin Losey

Hair repair tips from the pros.

Everyone has bad hair days, but what do you do when an unbearable cut, color, or perm happens to you? These emergencies deserve expert attention. Read on to find step-by-step instructions from salon professionals on handling your hazardous hair.

Emergency: Terrible Trim
You look like an ill-tempered kindergartener cut your hair.
Step 1: Put Down the Scissors. Taming your trim at home “will most likely make it much worse,” says Melissa Bridgers of OC-61 salon in New York City. “A stylist will have more ideas and experience to suggest ways to reshape."

Step 2: Call a Salon (and for the record Supercuts is not a salon). Bridger says “call a stylist immediately, even if you have to leave a message. Most stylists will do their best to make time for you.” If you return to the same salon, you shouldn’t be charged for a fix. If this is a home trim, “be flexible, make yourself available for a good portion of the day,” Bridger suggests. Hang out at the salon, so when an opening comes up, you can slip in.

Emergency: Pitiful Perm
You wanted Sarah Jessica Parkers’ wavy locks, but instead you look like Richard Simmons!

Step 1: Wash your hair. Perms take 24 hours to set; washing may prevent the texture treatment from taking effect.

Step 2: “Use a deep conditioner or a hot oil treatment”, says Tracy Jones of Paul Mitchell: The School in Danbury, Connecticut, this will relax the hair and prevent any help repair damage from the perm.

Step 3: If all else fails, call a professional. Bridgers recommends doing so within two weeks. The simplest solution may be layering the hair, which can help the shape of the body. A gentle treatment will also relax the perm “without making it stick straight.” Good stylists will work with you until you are satisfied with your hair. If you’re afraid to go back to the same stylist, ask around and find one with lots of perm experience. Be sure to describe what your hair has endured.

Emergency: Catastrophic Color
You wanted to be a blonde bombshell, but your hair just looks bombed.

Step 1: Don’t attempt to fix it yourself. Hair coloring is complicated—even some stylists don’t do color. Seek a seasoned professional.

Step 2: Make an appointment within a week so that you are not charged to color additional growth. Find a color expert and arrange for a consultation (almost always free) so they can assess your color disaster. “Color correction is an intensive process; which may require several appointments and be very expensive,” Bridgers says.

Step 3: It is much easier to darken light colors than to lighten locks that have gone too dark, Jones says. Adding a semi-permanent gloss, which is less harsh, can darken your shade. When a color requires lightening, the hair must be stripped. This can cause more damage and dry our your tresses, which is why using an experienced colorist is your best bet.

A Formula to Prevent Overeating

woman dining on patio

A Formula to Prevent Overeating

by Trisha Gura

Follow these guidelines to help you eat less and enjoy your dining experience.

So much goes on around the table while you're eating, and so much of it can affect your appetite. Subtle cues—lights, temperature, aromas, the shape of a wine glass, a whiff of espresso—can all tempt you to overindulge.

But a recent analysis of dozens of studies on "food ambience" (those factors around you that tickle the senses) suggests you don't have to give in. Instead, experts say, you can make the environment work for your waistline. Here's how:

Look before you eat
The brighter the lights, the quicker you'll eat. Physiologically speaking, light intensity revs up the nervous system, and you'll often respond by eating too fast. Result: You'll end up stuffing your stomach before your brain can tell you that you're full. Unfortunately, dim lighting is no solution, because it can hide signals of satiety. "We lose track of what we have eaten," says Brian Wansink, PhD, a nutrition-science expert at the University of Illinois at Urbana-Champaign. That's why people tend to eat more in candlelit restaurants; they linger, picking at their plates even if they're full.

The antidote: If you have to eat in a brightly lit restaurant like a fast-food joint, Wansink says, remind yourself—repeatedly—to eat slowly. In dimly lit restaurants with more romantic settings, pick one: drink, appetizer, or dessert. And keep yourself attuned to your feelings of fullness. When they come, ask your server to box up what you haven't finished.

Dine on the patio
As a general rule, the hotter the climate, the less people eat, says Nanette Stroebele, PhD, a neuropsychologist at the University of Colorado Health Sciences Center in Denver. She co-authored the recent report on food ambience in Nutrition. Heat slows down your metabolism, so your energy needs and your hunger decline as the mercury rises. Use that to your benefit.

The smart strategy: Ask for an outdoor table whenever the weather cooperates. Out where it's balmy, people seem to prefer food that's less dense and usually less caloric (salads instead of mashed potatoes, for example).

Tame your tableware
Supersized portions, whether it's French fries or frittatas, can make you think bigger is normal. That may override your "I'm full now" body sensors. Just as influential are the size of your plate and the shape of your cup. It's called the size-contrast effect, Wansink says: Bigger plates trick people into believing they're getting smaller servings. So do short, fat glasses. Even bartenders—renowned for their ability to "eyeball" a shot of alcohol accurately—will fill a shorter glass with up to 31 percent more than they pour into a tall, narrow one.

The solution: Avoid jumbo plates, and choose taller, thinner glasses.

Play hard to get
"People tend to eat almost everything you put in front of them," says John DeCastro, PhD, a professor and chair of the department of psychology at the University of Texas at El Paso. Working alongside Stroebele on the ambience study, DeCastro found that convenience is one of the strongest triggers for overeating and snacking.

Wansink demonstrated the power of proximity in 2002, when he and colleagues gave a gift of Hershey's Kisses to some university secretaries as part of a study. The secretaries ate nine Kisses daily when the candy was on their desks in transparent bowls. Consumption fell to an average of six and a half candies when the sweets were placed in opaque containers with lids, and only four when the bowls were positioned three steps away. That's a difference of up to 2,500 calories a month—and a prescription for gaining nearly 12 pounds per year.

The answer: At family gatherings and other occasions when overeating is likely, serve the food—and then put the serving platters on the counter or even in another room. Buy fewer ready-to-eat snacks, de Castro says, so you'll have to work harder to nibble when you're not hungry. Parcel out snacks into single-serving zip-top bags, Wansink suggests, and avoid buying food in bulk. What if you just can't resist the price on that 60-count box of granola bars? Stow away the extras in the back of the pantry. Out of sight, out of mind, out of tummy.

Policy reversal leaves hospitals scrambling

Four months ago, Houston's six stand-alone psychiatric hospitals were forced to cut back by 85 beds because Medicaid would no longer reimburse them for treating many of their mentally ill patients.

Now the hospitals are scrambling to rehire staff and reopen bed space because Medicaid has reinstated the payments.

"We do have a vacant unit," said Lois Moore, administrator of the University of Texas Harris County Psychiatric Center. "Now all we need to do is staff it."

The Centers for Medicare and Medicaid Services reversed its policy in response to a special waiver request by the state Health and Human Services Commission. In a May 1 letter, CMS notified state officials that Medicaid-reimbursed HMOs would be allowed to cover people treated in psychiatric hospitals.

In Harris and 27 other Texas counties, Medicaid patients receive their health coverage through a managed-care program called STAR+PLUS.

Dr. George Santos, medical director of West Oaks Hospital in Houston, said Friday that elected officials and mental health advocates from the area had joined forces to push for the agency's reversal.

Now he said the hospitals must rebuild their staffs of nurses and technicians, which won't be easy.

"What hasn't changed is the ongoing crisis in nursing shortages in this community, in the state," said Santos. "Although the regulatory stuff has been reversed, all the hospitals are struggling to locate and hire enough staff to reopen their units."

Betsy Schwartz, executive director of the Mental Health Association of Greater Houston, said she is thrilled that the federal agency reversed its policy but is concerned that resources to help the mentally ill are still too limited.

"We have to keep our eye on the larger issue," she said, "which is that thousands of adults and children with major illnesses are not able to access the treatment they need and deserve."

Weight & see? Nah! Consumers scarf up new diet pill

Weight-conscious consumers seeking the next big thing to help them go from lumpy to luscious ran out yesterday to buy Alli - the first FDA-approved over-the-counter diet pill.

Alli's promise of helping calorie counters lose 50% more weight than by dieting alone apparently outweighs its warnings that the drug can cause users to lose control of their bowels.

At a Manhattan Duane Reade, Debbie and Renee Boyer, sisters-in-law visiting the city from Virginia, each paid $59.99 for a starter pack of Alli, which works by preventing the body from digesting the fat in food.

Both women said they've been concerned about weight gain since hitting menopause.

"I want to lose 20 pounds, just to feel good about myself," said Debbie Boyer. "I wouldn't mind some mild side effects [from dieting], but I won't go and do liposuction."

Renee Boyer said Alli's FDA seal of approval gave her comfort. "Weight has been something I think about every day since my 30s, after I've had children," she said.

A number of drugstores across the city told the Daily News that they had already sold out of their small allotments of Alli and had received numerous phone calls about its availability.

Distributed by GlaxoSmithKline, Alli is a half-dose of the prescription drug orlistat, which is sold by the trade name Xenical. Alli's Web site warns that the drug's fat-blocking activity can lead to "gas with oily spotting" and "more frequent stools that may be hard to control."

On the off chance that someone finds this disturbing, "The excess fat that passes out of your body is not harmful," the Web site says. "In fact, you may recognize it as something that looks like the oil on top of a pizza."

That sounded just a bit too disgusting to Bronx shopper Carmen Malgieri, 33, a student and homemaker from Morris Park.

"This can't be healthy for you...I wouldn't use it," she said. "Would you really want bloating if you're already fat? What are they going to do, sell you the pill and then sell you Depends on the side?"

While the risk of soiling oneself may certainly sound undesirable, other things could always be worse: Federal health advisers yesterday rejected another weight-loss drug, rimonabant, after hearing testimony that it causes an increased risk of suicidal thoughts.

Muscle cream caused NYC teen's death

NEW YORK - A medical examiner blamed a 17-year-old track star's death on the use of too much muscle cream, the kind used to soothe aching legs after exercise.

Arielle Newman, a cross-country runner at Notre Dame Academy on Staten Island, died after her body absorbed high levels of methyl salicylate, an anti-inflammatory found in sports creams such as Bengay and Icy Hot, the New York City medical examiner said Friday.

This undated family photo provided to the Staten Island Advance and released Saturday, June 9, 2007  shows Arielle Newman. Newman, 17, a cross-country runner at Notre Dame Academy in New York's Staten Island, died on April 13, 2007, after her body absorbed high levels of methyl salicylate, an anti-inflammatory found in sports creams such as Bengay and Icy Hot, the New York City medical examiner said Friday, June 8, 2007. (AP Photo/Courtesy Newman family via The Staten Island Advance)
The medical examiner's spokeswoman, Ellen Borakove, said the teen used "topical medication to excess." She said it was the first time that her office had reported a death from using a sports cream.

Newman, who garnered numerous track awards, died April 13. She had gone to a party the night before, then returned home and spent hours talking with her mother.

Methyl salicylate poisoning is unusual, and deaths from high levels of the chemical are rare.


"Chronic use is more dangerous than one-time use," Edward Arsura, chairman of medicine at Richmond University Medical Center, told the Staten Island Advance on Friday. "Exercise and heat can accentuate absorption."

Dr. Ronald Grelsamer, of Mount Sinai Medical Center, said Newman had a very abnormal amount of methyl salicylate in her body.

"She either lathered herself with it, or used way too much, or she used a normal amount and an abnormal percentage was absorbed into her body," he said.

Her mother, Alice Newman, said she still couldn't believe her daughter's death was caused by a sports cream.

"I am scrupulous about my children's health," she told the Advance. "I did not think an over-the-counter product could be unsafe."

Cancer risk cut

LARGE doses of vitamin D may reduce the risk of cancer, a study has found.

Women who took calcium and a dose of vitamin D almost three times the US Government's recommended daily intake for middle-aged adults saw a 60 per cent lower incidence of all cancers than women not taking the vitamin.

The four-year study, conducted by researchers at the Creighton University School of Medicine in Nebraska, was published in the American Journal of Clinical Nutrition. It involved nearly 1200 women over 55.

Joan Lappe, a professor of medicine who led the study, said vitamin D may be an effective way to guard against cancer but many people do not get enough.

The body makes the vitamin after being exposed to sunlight. Not many foods are naturally rich in it. It is found salmon and milk commonly is fortified with it.

Nigeria: Tobacco - Why the Smoke Billows Higher

World No Smoking Day was marked on May 31. Uthman Abubakar takes a look at the habit, and shows that the global population of smokers is on the rise

For Ya'u Abdu, tobacco is an all-times and an all-moods consumable. When he is angry, he consoles himself with a stick of cigarette; when he is happy, he lights one. When he is hungry, he sustains himself with a stick; when he takes a meal, he tops it up with one. When he rises from bed in the morning, he starts the day with a stick; when he retires to bed at night, he ends the day with one.

He wouldn't want to be described as a chain smoker, but he is a compulsive one - most times he lights a stick after an average of every twenty minutes, or thirty minutes, sometimes. He rarely breathes for an hour at a stretch without a stick between the fingers or between the lips at the left end of his mouth, when he is working on a pair of shoes or sandals.

He seems happily married to his beloved, call it affordable, brand of cigarette - Aspen King size, although he sometimes takes London King Size. He takes Rothmans King Size and Benson and Hedges King Size when he is offered by persons who can afford them.

Ya'u Shushana is a cobbler at Suleja in Niger State. He smokes his cigarette as much as he wants, or as much as he can afford. How it erodes his health and his meager earnings seems entirely the business of whoever pities him over that. For him, it is a part of life, it seems, not a part of death. With a stick of cigarette, he gets moving.

Ya'u is among an estimated regular tobacco smoking population of 1.3 billion worldwide. According to World Health Organisation (WHO) studies, tobacco is the second major cause of mortality in the world, with half of its regular smoking population - 650 million, liable to dying of smoking it eventually. It is feared that if current smoking patterns continue, tobacco will kill some 10 million worldwide each year by 2020, with 70% of these deaths occurring in the developing countries. Now, one in every 10 adults worldwide is killed by tobacco, adding up to an estimated 5 million every year.

Secondary, passive or second-hand smoking is equally dangerous. Hundreds of thousands of people, who have never smoked tobacco, die each year as a result of illnesses related to inhalation of other people's tobacco smoke. Half of all children worldwide are exposed to tobacco smoke, particularly in the home. According to estimates, at least 200,000 workers die each year worldwide from secondary smoke exposure at their respective workplaces. A person is a secondary, passive or second-hand smoker of tobacco if he does not smoke it directly, but inhales the smoke puffed out or exhaled by its direct smoker - primary, active or first-hand smoker.

Most tobacco smokers worldwide begin the habit in expression of juvenile delinquency, adolescent come-of-ageness or status symbol, peer group influence or emulation of smoker-parents and elder relations and close associates.

Tobacco-inflicted ailments

According to studies, tobacco is responsible for more than 25 diseases in humans. These include pulmonary diseases, cardiovascular diseases, high blood pressure, impotence, wrinkling of skin, mouth disease, respiratory infections and ulcer. Rise in cigarette smoking by parents may also elucidate asthma epidemic in children. A recent study shows that cigarette smoking inflicts head and neck cancer more than boozing.

No other consumer product, it is believed, is as dangerous, or kills as many people, as tobacco. Smoking increases the risk of erectile dysfunction because blood flow into the penis is blocked by atherosclerosis. Smoking causes abnormal sperm shape, impaired sperm motility damage, reduced number of sperms and reduced volume of ejaculate. Tobacco smokers are also less productive while they are alive due to increased sickness. A 1994 report estimated that the use of tobacco resulted in an annual global net loss of $200 billion, a third of this loss being in developing countries.

Smokers risk damage to almost all major organs in their bodies. The list of diseases caused by tobacco now includes cancers of the kidneys, stomach, cervix, and pancreas, as well as leukemia, cataracts, pneumonia, and gum disease. These illnesses are in addition to diseases previously known to be caused by smoking- bladder, esophageal, laryngeal, lung, oral, and throat cancers, chronic lung diseases, coronary heart and cardiovascular diseases, and sudden infant death syndrome.

The situation is profoundly pathetic with pregnant women who smoke. The developing embryo - and later the newborn infant - encounters many risks from faults in its genes, following the mother's cigarette smoking. The infant loses weight.

Smoking also reduces overall health, contributing to conditions such as hip fractures, complications from diabetes, increased wound infections following surgery, and various reproductive problems. Smoking cigarettes with lower machine-measured yields of tar and nicotine does not help. "There is no safe cigarette, whether it is called 'light,' 'ultra-light,' or any other name," U.S. Surgeon General Dr. Richard Carmona once commented. "The science is clear: the only way to avoid the health hazards of smoking is to quit completely or to never start smoking," according to Health and Human Services.

A clear scientific consensus grounded in many studies holds that exposure to tobacco smoke causes serious and deadly illnesses among adults and children. Tobacco smoke contains more than 4000 known chemicals, of which more than 50 are carcinogens. Second-hand smoke also causes severe forms of heart disease and many respiratory and cardiovascular illnesses, most of them deadly.

Exposure to second-hand smoke also carries economic costs for individuals, companies and the society at large. These costs relate not only to direct and indirect payments for medical expenses, but also to loss of productivity.

The hazards of primary, active or first-hand smoking are known by all. Very dangerous now is the substantial persistent ignorance on the hazards of secondary, passive or second-hand smoking. WHO laments gravely: "The tobacco industry has constantly misled and misinformed the public on both health risks and dangers of passive smoking. It has continued its efforts to slow down the implementation of effective legislation aimed at protecting workers and the public from second-hand smoke."

May 21st 2003 was a historic day for global public health. At the 56th World Health Assembly, WHO's 192 Member States unanimously adopted the world's first public health treaty, the WHO Framework Convention on Tobacco Control. Negotiated under the auspices of WHO, this new treaty is the first legal instrument designed to reduce tobacco-related deaths and disease around the world. Now the key is for countries to sign and ratify the convention as quickly as possible. Since then, No Smoking Day is celebrated the world over on May 31 of every year. The 2007 World No Smoking Day was celebrated last Thursday, May 31.

The treaty became the world's first international public health treaty when it came into force on February 27, 2005. It has been signed by 168 countries and is legally binding in 147 ratifying countries representing over 2.3 billion people. Notable non-parties (currently at 48) are Russia and the United States of America.

The treaty is sponsored by the World Health Organization's Tobacco Free Initiative, an organization dedicated to reducing the health effects of tobacco use. The Tobacco Free Initiative is part of the WHO Noncommunicable Disease and Mental Health Division based in Geneva, Switzerland.

The purpose of the treaty is to set broad limits on the production, sale, distribution, advertisement, taxation, and government policies towards tobacco.

The tobacco industry has sought to limit the influence of this treaty, but with limited success. Most nations worldwide are finding that ever larger numbers of their citizens are getting ill and dying of lung cancer, emphysema, and heart disease sequel to the rise in tobacco smoking. Since national health systems in many nations pay for treatment of these diseases, there is a strong financial incentive for governments to control spending on health and thus discourage tobacco use.

The Nigerian situation

Like most modern societies, in Nigeria, cigarette smoking is more or less perceived by young people as a glamorous thing. A survey conducted by the United States Centre for Disease Control in recent years in Cross River State in Nigeria, found that as many as 45% of the young people surveyed think boys who smoke and 28% think girls who smoke have more friends. Again, 17% think boys who smoke and 16% think girls who smoke, look more attractive. Therefore, as many as 22% of the sample population currently use tobacco with as many as 20% of those who had never smoked likely to start smoking in the following year. A different study found fewer smokers (only 4.4%). According to the survey, kids smoke in the street, and the situation is seen as something that concerns the individual's family rather than one for the police or social workers. These people probably have their hands a bit too full to care, and it is not seen as their role to find a solution.

Smoking is seen as attractive probably because of the way it is presented in Nigeria. Young people see their role models-film stars, musicians, and celebrities-smoking or portraying smoking as something glamorous. Many also see it as a status symbol, a way of telling your peers and contemporaries that you have come of age. In Nigeria there is no age restriction on buying cigarettes. People sell anything to anybody without batting an eyelid. Most adults prefer to send children to buy cigarettes and alcohol for them. There are effectively no laws in this regard.

"I started smoking when I was 13," Ya'u Shushaina, 45, obliged, explaining, "I started with Flight, Target and SM (Sweet Menthol). I started in Kano when I was accompanying my elder relations and friends to Sheila (WAPA), Plaza or Queens Cinemas whenever my uncle took me to Kano. Those were the good old days. Whenever we were watching the film, we would do whatever we liked, like spoilt children."

According to the cobbler, "I started by smoking the leftover, the butt thrown away or about to be crushed by the older members of our cinema-going group. The first time I took it, I was severely dizzy, and it knocked me off, and I fell. My elders laughed at me and I felt ashamed. Since that day, I learnt to withstand the force of the smoke. Shortly after, since we were not working to earn money, we learnt to dupe our aunties. Whenever they sent us to buy food items or soup ingredients at the market or at Kofar Mazugal abattoir, we would always find a way of reducing the money to collect enough for the daily package of a cinema ticket, sticks of cigarette and a bottle of soft drink, including a wrap of biscuits, if we could still afford it after buying the first three."

Ya'u said to this day, he had smoked no fewer than 15 brands of cigarette. He said since he started smoking in the mid seventies, he did not do it for only two years at a stretch in the early eighties, when he ailed severely, and his father threatened that if he did not stop smoking, he would hands-off him on any treatment.

"I know it is injurious to my health. Every smoker knows that, of course. But, like most smokers, I find it difficult to conduct my daily life without it. We know it brings death slowly, but cigarette aggravates your ailing situation when you don't feed well. Death comes when it will. Because it is already in our blood, we believe it gives us life, we believe it moves us in all our daily activities. But I don't mean to tell you that I don't hope to stop smoking one day. I pray to stop it before I die," he offered. According to studies, there are several millions of tobacco smokers in Nigeria. The exact figure has not been determined yet.

The smoking prevalence in the general population in Nigeria is high, judging by a 1990 survey of 1270 adults which showed that as many as 24% of men and 7% of women smoke cigarettes on a daily basis. The adult population reportedly increased its consumption by as much as 32% from what it was in 1970. Another survey, this time in 1998, suggests that there may have been a decline (15% of men and 2% of women), the possibility of the actual current prevalence being higher, cannot be ruled out.

This situation is largely because many cigarettes consumed in Nigeria today are smuggled into the country ,and the fact that a lot of adults would not easily own up to indulging in the habit. The amount of smuggling is high to avoid the huge taxes and import duties on tobacco. Apart from the taxes and duties, traders also smuggle to avoid corrupt customs officials, who inflate the duties and charge their self decreed illegal duties and taxes. As to why adults do not easily own up, the fact remains that although the practice is widespread, tobacco smoking is still not socially acceptable here in Nigeria. Few ladies would own up for fear of scaring away prospective suitors. A good number of young people would even not own up, so as not to incur the wrath of their parents and guardians.

In 1990, during the military administration of President Ibrahim Badamasi Babangida, the then Minister of Health, the late Professor Olikoye Ransome Kuti, initiated a ban on smoking in public places and ensured the enactment of the Anti-Tobacco Decree of 1990. The decree bans smoking in public places and mandate tobacco manufacturers to put on the pack of their cigarettes a warning that smokers are likely to die young and tobacco smoking is injurious to your health. This caveat was also to be added at the end of adverts on radio and television, long before the voluntary withdrawal of such adverts by the manufacturers.

Dr. Mike E. Anibueze is the National Coordinator, Non-communicable Diseases Control Programme of the Federal Ministry of Health. "A 1991 statistic shows that about 4.14 million Nigerians were smoking, 11% of who were heavy smokers. Heavy smokers are those who smoke above 10 and above sticks a day. But I must say that the data should be much higher than that now. If you check the population growth rate and use it to extrapolate, you will see that it is incredible how many people should be smoking now. Even with the very aggressive adverts by the tobacco companies, you will see that much more people should be smoking in Nigeria now. We are currently trying to do a survey that will give us the accurate information on that."

According to the expert, "We also are aware that smoking is a major problem because smoking and tobacco use is a bridge factor for almost all non-communicable diseases - hypertension, heart diseases, asthma, tuberculosis, pregnancy-related diseases and all others."

Dr. Anibueze delved into the antecedents of laws on tobacco control in Nigeria. "The first major attempt by government to control tobacco smoking was in 1990, with that decree which was championed by Professor Ransom-Kuti at that time. It was banning smoking in public places. It also talked about advertising, that if you have to advertise, you must tell people that it kills, that it is injurious to health. That was the first attempt. Incidentally, the implementation of that Decree 20 was not efficient and effective. Therefore, there was need for government to protect its people. There was a bill tabled before the National Assembly by a member. It was passed by the House of Representatives, but the Senate did not pass it. Therefore, it was not law. What it tried to do was focus on adverts and smoking in public places."

"However," he went further, "it is important to inform you that we are very grateful to the Advertising Practitioners Council of Nigeria (APCON) because a resolution by them which prohibited their members from advertising any tobacco product, and it was from a negotiation with the ministry of health. That ban has been most effective, more effective than even our decree, because now you don't see any advert on tobacco anymore, you won't see anywhere. That was just by a resolution of APCON. Imagine when we now come with this bill which prohibits advert, promotion and sponsorship. We already have a draft of this bill which will be discussed next month at the stakeholders' level, multi-sectoral level. All line ministries - Trade, Commerce, Industries, Justice, Education, Customs, Police, Youth and Sports, Environment and Science and Technology."

Dr. Anibueze said to be represented at the discussion are also WHO and NGOs concerned with tobacco control as well as Journalists Against Tobacco. "We will look at this bill. If it is approved, we will send it to our top management in the ministry."

He gave the absence of a law dealing with it as the reason why tobacco smoking seems intractable in the Nigerian society. "No strong law. Now if this country comes out with a law that takes care of demand issues, supply issues, fiscal measures, the sales and consumption will be effectively addressed. If you increase the cost of cigarette by 10%, you will reduce smoking by about 4%. These are some of the fiscal measures we must adopt, and also check illicit trade, because with illicit trade when they bring it across the border without paying tax, they can sell it very cheap, which encourages people to smoke."

The bill also spells out penalties. "If you sell cigarette to someone below 18 years you can go to jail or pay a fine. Smoking in all public places, all government buildings, workplaces, stadia, cinema halls, theatres and markets are all captured in the bill."

The legislation covers tobacco farming. "Government should inform tobacco farmers on the effect of tobacco and get them to change. If you address the tobacco farmers, if you get them to change, the factories will not see it to buy. They are an important part of our control measures, so they should be addressed. To address them, we are going to work with the Ministry of Agriculture to teach them how to be farmers of some thing else, and they are going to be happy because with the tobacco companies, such farmers are the most impoverished among farmers in the world. The companies provide them everything to grow the product and at harvest they deduct all such facilities cost, leaving the farmers with a pittance."

He said government would seek the help of religious leaders to preach to people against smoking. "They have a big role to play, because all our religions - Christianity, Islam, prohibit taking anything that kills. They all preach against you taking something that will kill you."

Dr. Anibueze revealed: "Because smoking is an addiction, it is not very easy to stop. It is easier to prevent people from going into it. For those who are inside, we must provide a away for them to come out. We have, therefore, planned to set up cessation clinics all over the country. For any medical check you come for, the doctor will ask if you smoke. If you say you do, he will counsel you like people are being counseled on HIV/AIDS. There are treatments now available, not in this country though, but abroad, but we are trying to negotiate with some of our partners to see how they can send in these drugs which contain a different make of nicotine which is not injurious to health. With this drug, you fade down consumption of cigarette until you leave it. Nicotine is the greatest addictive substance known to man."

Already, some state governments in Nigeria, most prominently Lagos, Kano and Gombe have sued the tobacco industry to court over the effect of the ever billowing smoke to the health of their peoples, demanding compensations amounting to billions of naira for environmental pollution.

Mallam Ahmad Muhammad is learned in Islamic jurisprudence. "Tobacco smoking is prohibited in Islam. Anything that will in the near or distant future be injurious to your health is prohibited. It is also prohibited because it has no nutritional value for the human body. It has nothing for your body. If you buy that thing that is not important to your body at all and you burn it, then you are being extravagant. Extravagance in Islam is prohibited. So, if you consider the disease it inflicts in you and the extravagance, wasting money on something that does not benefit you and instead injure you, you will arrive at the conclusion that tobacco smoking is directly a prohibited act."

As government at various levels admits lack of any legislation banning tobacco smoking and makes systematic efforts to tackle the injurious habit, the population of tobacco smokers in the Nigerian society, as is generally the case globally, is on the rise. The smoke billows thicker and higher.

HIV drug is recalled over contamination

A drug used to treat HIV-infected adults, adolescents and children over three years of age has been recalled.

The Irish Medicines Board confirmed this morning that the drug Viracept, which is an antiretroviral medicine, has been recalled after it was informed that some batches of the product were contaminated.

The contaminant in question is known to be harmful to DNA and the level of risk involved has yet to be established.

18 Irish HIV-infected patients are currently taking the drug.

Viracept has been withdrawn with immediate effect from European markets.

Genetic find set to transform medicine and serve millions

An unprecedented selection of genes that contribute to common diseases has been identified by the biggest survey of the human genome. The discovery promises to transform treatment and diagnosis of everyday health problems.

The study, which screened DNA samples from 17,000 British volunteers, has identified 24 genetic variants that influence six common conditions that together affect tens of millions of people.

Half the genes have effects that are new to science, and the findings open new approaches to research into type 1 and type 2 diabetes, heart disease, Crohn’s disease, bipolar disorder and rheumatoid arthritis.

Genetic variants that may affect a seventh disorder, high blood pressure, have also been highlighted, though these links have yet to be confirmed.

The discovery by the Wellcome Trust Case Control Consortium is a landmark in humanity’s ability to understand our genetic code, illustrating how variations in DNA make different people susceptible to diseases. As the seven studied conditions and the genes that influence them are common, the results should help scientists to design therapies and screening techniques from which millions will benefit.

Many of the new genes lie in areas of the genome that were not previously thought to be related to the diseases in question. As all the variants have small effects, which predispose to disorders rather than inevitably causing them, the study should also reveal environmen-tal factors that matter as well.

“We have known for a long time that genes play a large role in common human diseases such as heart disease, diabetes and many psychiatric disorders,” said Professor Peter Donnelly, of the University of Oxford, who led the research team. “What we have not known is which parts of the genome are involved.”

“Many of the most common diseases are very complex, part nature and nurture, with genes interacting with our environment and lifestyles. By identifying the genes underlying these conditions, our study should enable scientists to understand better how disease occurs, which people are most at risk and, in time, produce more effective, more personalised treatments.”

In the study, published in the journal Nature, more than 200 scientists took DNA samples from 2,000 individuals with each of the seven diseases and from 3,000 healthy control subjects. The study compared 500,000 genetic markers to identify which were more common in people with disease.

This technique, whole genome association, can find genetic variants that have small effects. The new variants are carried by between 5 per cent and 40 per cent of the population.

Most raise the risk of developing a disease by up to 40 per cent if one copy is inherited, and by double this in people with two copies.

Details of several genes identified by the consortium have already been published, including the FTO gene that influences obesity and a cluster that affects type 2 diabetes.

The most exciting results concern type 1 diabetes and Crohn’s disease, a bowel disorder. Specialists in each disease will be watching progress in the others in search of clues. “If there is a breakthrough in Crohn’s disease, we will be looking at it in type 1 diabetes,” said Professor John Todd, of the University of Cambridge, who led the type 1 diabetes arm of the research.

Mark Walport, director of the Wellcome Trust, said: “This research shows that it is possible to analyse human variation in health and disease on an enormous scale.”

Hope for six conditions

Bipolar disorder Psychiatric illness that affects 100 million people worldwide. One new genetic area reliably linked. Many other genes likely to have a small effect on risk

Coronary heart disease Britain’s biggest killer, causing 105,000 deaths annually. Genetic area on chromosome 9 doubles risk in the 20 per cent of people who have two copies, increases risk by 50 per cent in the 50 per cent of people with one copy of the variant

Crohn’s disease Inflammatory bowel disorder that affects up to 60,000 people in Britain. Three new genes discovered that raise the risk by 40 per cent. The study confirms six other previously identified genes are also linked

Rheumatoid arthritis Auto-immune condition affecting 387,000 people in Britain. One genetic region confirmed to have impact on women

Type 1 diabetes Insulin-dependent form of the condition that usually begins in childhood, affecting 350,000 people in Britain. Four genes found that have an effect, raising risk by up to 40 per cent when people have one copy. Effect of three other genes confirmed

Type 2 diabetes Adult-onset form of the condition, affecting 1.9 million people in Britain. Three new genes that affect risk identified, including the FTO gene that contributes to the risk of obesity

Alta. surgeons complete 18 transplants in 56 hrs

Surgery

The University of Alberta Hospital in Edmonton has set a record. In just 56 hours, surgeons performed 18 transplants on 15 patients.

The complex and delicate operations were undertaken by a large team of health-care professionals at between May 9 and 11.

In all, there were two combination heart and double lung transplants, two double lung transplants, two heart transplants, three liver transplants, five kidney transplants and one combination kidney-pancreas transplant.

In two and a half days, the hospital completed as many transplants as it normally completes in a month.

"The thing that's amazing is the fact that we put all the teams together and actually handle that volume in such a short period," surgeon Dr. John Mullen said Wednesday.

It was all due to an unusual supply of donor organs that became available.

"This was an exceptional few days," said Karen Olivier of the Human Organ Procurement and Exchange program." I sincerely hope this celebratory day reminds people to sign their donor cards and discuss their wishes with their family.''

The patients who received the new organs hail from communities in British Columbia, Alberta and Saskatchewan, and all continue to recover.

One of them is John Kaminsky. The 60-year-old was diagnosed with a potentially fatal lung condition called pulmonary fibrosis. To add to his failing health, shortly after his diagnosis, he had a heart attack. The Vancouver lawyer was told he needed a heart and double lung transplant. One month ago, he got a lifesaving phone call.

"It was incredible," he told reporters. "Just an overwhelming sensation of... basically be were brought to tears because finally I had something to look forward to."

His wife, Barbara Kaminsky, thought she only had a bit of time left with her husband. Now, she says he's looking better than ever.

"He looks almost like the man I married 35 years ago. And now we have a new chapter of our life to look forward to, a chapter we thought maybe we wouldn't have together."

Dr. Norm Kneteman, spokesman for the transplant program, credits teamwork and careful planning for what some are calling a record-breaking achievement.

"These days tested the skill and stamina of many, many people, both inside the operating rooms and beyond,'' Kneteman said.

"Our team rose to the biggest challenge in our history. Hundreds of people worked to make this possible. As a result, 15 people have a new lease on life.''

Kaminsky says a month after his transplant operation, he is feeling strong and can't wait to go home.

"I will take care of this gift -- my new lease on life,'' he said.

Doane Recalls Batch of Ol' Roy Dog Food

Another pet food company has recalled bags of its dry dog food, but this time it's not because the food contains melamine-tainted ingredients imported from China.

Doane Pet Care is recalling a single lot of 55 pound bags of Ol’Roy Complete Nutrition dry dog food because they may be contaminated with salmonella.

The Manassas, Virginia-based company sold the food at 69 Wal-Mart stores in Maryland, North Carolina, Ohio, Pennsylvania, Virginia, and West Virginia. The company produced the potentially contaminated food at one facility in Virginia.

The recalled bags of food have the USC Code “6 05388 72076 4,” the lot number “04 0735 1,” and the Best Buy Date “Apr 13 ’08.”

“This voluntary recall has been issued because FDA (the Food and Drug Administration) detected Salmonella in the product,” the company said on its Web site. “Doane Pet Care has not confirmed the presence of Salmonella, despite extensive independent testing of duplicate samples.”

The company said it has not received any reports of illnesses linked to the food. It did, however, warn pet owners who handled the food that they may be exposed to salmonella -- especially if they do not thoroughly wash their hands after coming into contact with the product.

Salmonella is a bacteria found in the intestines that can cause food poising and gastroenteritis.

The company said pet owners should immediately stop feeding the food to their dogs.

A complete list of stores that sold the recalled food can be found on the company’s Web site:

www.doanepetcare.com/recall/stores.

Pet owners with questions about the recall can also call the company at 1- 800-624-7387.

Doane Pet Care emphasized this action is not connected to the massive recall of millions of bags of dog and cat food -- contaminated with the chemical melamine -- announced in March.

The presence of that chemical triggered one of the largest pet food recalls in U.S. history. It’s also blamed for the deaths and illnesses of thousands of dogs and cats nationwide.

The FDA discovered melamine in the wheat gluten, corn gluten and rice protein imported from China and used to make the pet foods.

Africa AIDS war at pivotal point

DURBAN, June 6 - South Africa is at a pivotal point in the battle against AIDS and may emerge as a role model for other African nations devastated by the disease, the director of the WHO's HIV/AIDS department said on Wednesday.

In an interview with Reuters at the Third South African AIDS Conference, Dr. Kevin de Cock said he sensed a new consensus and determination to halt the spread of the epidemic in the country, where an estimated 12 percent of 47 million people are infected with HIV.

"I think the developments in South Africa are encouraging," de Cock said, adding there was a different mood than in previous years among activists, researchers and health care officials attending the four-day conference in Durban.

"Once in a while you get the feeling there is something special... or that the temperature has changed," de Cock said. "I got the feeling yesterday that this is different from the last time I was here."

He cited the South African government's unveiling of a revamped AIDS strategy in March as a positive milestone, although success would depend on concerted follow-up by the government, health care sector and civic society.

South Africa, criticised in the past for failing to take strong action against the disease and for questioning widely accepted HIV science, has now vowed to dramatically expand access to lifesaving AIDS drugs and increase HIV testing and counselling programmes for those most at risk of infection.

Although it has vastly greater resources and an established health care network, South Africa is grappling with a crippling shortage of health care workers that could derail hopes it can one day provide AIDS-related assistance to its neighbours.It hopes to have one million HIV-positive people on antiretroviral medication by 2011, a five-fold jump from the present number.

If it achieves that target, AIDS mortality and new HIV infection could sharply decline -- about 1,000 South Africans currently die each day from AIDS and related diseases and another 1,500 become infected with HIV. De Cock said the government's ambitious plan could provide a blueprint for other African nations and allow South Africa, the continent's economic powerhouse, to play a leadership role on AIDS in Africa.

"What happens in South Africa in terms of AIDS in a way may be more important than anywhere else in the world, and for the African continent it is immensely important," he said.

"South Africa should be playing a leadership role in Africa.

Although it has vastly greater resources and an established health care network, South Africa is grappling with a crippling shortage of health care workers that could derail hopes it can one day provide AIDS-related assistance to its neighbours.

" Thousands of South African doctors, nurses and medical technicians have left for jobs in Europe, Australia and North America, leaving many communities without a primary care provider.

The exodus has hampered efforts to get key target groups, especially pregnant women and those infected with tuberculosis, tested and treated for HIV.

The government has responded by extending internship periods for qualifying doctors as well as introducing other measures to plug the growing health care staffing gap.

Genetic risk factors for seven diseases identified

The largest-ever study of the genetics behind diseases has found 24 genetic risk factors -- half of them completely new -- linked to seven common diseases, British scientists announced Wednesday.

The discoveries are the biggest identification yet of disease-associated genes, and could one day help researchers decipher the biology of major illnesses, perhaps leading to more effective drugs.

The Wellcome Trust Case Control Consortium has been studying the genetics behind some of most common and mysterious diseases. The consortium has examined DNA samples from 17,000 people across the United Kingdom, bringing together 50 research groups and 200 scientists in the field of human genetics from dozens of U.K. institutions.

Over two years, they have analyzed almost 10 billion pieces of genetic information as they compared the genomes of diseased and healthy volunteers.

The researchers have been able to identify more of the genes known to play a role in the development of:

  • Crohn's disease
  • Rheumatoid arthritis
  • Type 1 diabetes
  • Type 2 diabetes
  • Bipolar disorder
  • Coronary heart disease
  • Hypertension

Scientists have known for years that the causes of our most common diseases are a combination of lifestyle and interaction with our environment, and genetic predisposition. But researchers have been trying to work out which parts of the genome -- the 3 billion sub-units of DNA in our cells -- are actually responsible for each disease.

"By identifying the genes underlying these conditions, our study should enable scientists to understand better how disease occurs, which people are most at risk and, in time, to produce more effective, more personalized treatments," says University of Oxford Professor Peter Donnelly, who has led the Wellcome Trust Case Control Consortium.

"We are just scratching the surface," Donnelly told reporters.

The findings are published in the journals Nature and Nature Genetics.

Among the most significant new findings are four chromosome regions containing genes that can predispose a person to Type 1 diabetes, and three new genes for Crohn's disease. For the first time, the researchers have found a gene linking these two autoimmune diseases, known as PTPN2.

"The link between type 1 diabetes and Crohn's disease is one of the most exciting findings to come out of the Consortium," says University of Cambridge Professor John Todd, who led the study into type 1 diabetes.

"It is a promising avenue for us to understand how the two diseases occur. The pathways that lead to Crohn's disease are increasingly well understood and we hope that progress in treating Crohn's disease may give us clues on how to treat type 1 diabetes in the future."

Research from the Consortium has already played a major part in identifying the clearest genetic link yet to obesity and three new genes linked to type 2 diabetes, published in April, in advance of the main study.

It has also found a major gene region on chromosome 9 identified by independent studies on coronary heart disease.

The consortium is continuing its work, searching as well for the genetic factors behind tuberculosis, breast cancer, autoimmune thyroid disease, multiple sclerosis and ankylosing spondylitis, a form of arthritis also known as Bechterew's disease.

Low Testosterone Linked To Shorter Life In Older Men

A new US study suggests that having low testosterone may shorten the lives of men over 50.

Researchers at the Department of Family and Preventive Medicine at the University of California, San Diego (UCSD) School of Medicine conducted a long-term study involving 800 men over an 18-year period and found that those with low testosterone carried a 33 per cent higher risk of death compared with those who had higher levels.

The study was reported to the Endocrine Society annual meeting in Toronto earlier this month and is one of a selection of articles published in The Endocrine Society's ENDO 07 Research Summaries Book. It was funded by the National Institute on Aging in the US and the American Heart Association.

Assistant professor and one of the report's authors, Dr Gail Laughlin said that:

"The new study is only the second report linking deficiency of this sex hormone with increased death from all causes, over time, and the first to do so in relatively healthy men who are living in the community."

She referred to the study's duration, averaging 18 years, and said this "strongly suggests that the association between testosterone levels and death is not simply due to some acute illness".

The study participants were men aged from 50 to 91 years, who were living in Rancho Bernardo, California. They had been attending the Rancho Bernardo Heart and Chronic Disease Study since the 1970s.

Ten years later, by the start of the 1980s, nearly one third (29 per cent) of the men had low blood testosterone. For the purpose of this study, low testosterone was defined as the lower limit of the range normally found in young male adults.

The nearly one third of men with low testosterone showed a 33 higher risk of death over the 18 years compared with men with higher testosterone. And factors such as smoking status, alcohol consumption, physical activity and pre-existing diseases like diabetes and heart problems did not account for the difference.

Testosterone levels tend to fall as men get older and the range varies widely.

Laughlin and colleagues found that the men with low testosterone were more likely to have:
  • Higher levels of inflammatory cytokines; these are biomarkers for inflammation which contribute to several diseases.
  • Larger waist measurement.
  • A cluster of cardiovascular and diabetes risk factors, collectively called the "metabolic syndrome" that is linked to having a larger waist.

The cluster of factors that characterize metabolic syndrome includes a waist bigger than 40 inches (35 inches for women), low levels of good cholesterol (HDL), high levels of blood fats (triglycerides), high blood pressure and high blood sugar.

Laughlin and colleagues also found that men in the low testosterone group were three times more likely to have metabolic syndrome than men in the higher testosterone group.

Although the study may suggest that hormone supplements might help older men with low testosterone, the authors suggest that weight control and exercise would be a better way to influence longevity.

Principal researcher and UCSD Distinguished Professor of Family and Preventive Medicine and chief of the Division of Epidemiology, Dr Elizabeth Barrett-Connor said:

"It's very possible that lifestyle determines what level of testosterone a patient has."

And she added that:

"It may be possible to alter the testosterone level by lowering obesity."

The authors took pains to point out that while this study suggests low testosterone may be linked with shorter life, it does not suggest that higher testosterone would be linked with longer life.

However, researchers at UCSD are planning to hold a randomized controlled trial to see if testosterone supplements can safely promote longer life.

Barrett-Connor said that while they were excited by the findings, they were not suggesting that men should start taking testosterone supplement in the belief it will prolong their lives. "We're not ready to take this to the prescribing pharmacist," she cautioned.

There are those who say that women tend to live longer because they have higher estrogen and lower testosterone, but the fact is, said Barret-Connor, "We don't know."

"Maybe the decline in testosterone is healthy and comes with older age. Maybe the decline is bad and is associated with chronic diseases of aging," she said.

Surgery begins on conjoined twin girls

CLEVELAND — Doctors began the first in a series of high-risk surgeries Wednesday to separate 3-year-old twin girls joined at the head.

Doctors hope to separate Tatiana and Anastasia Dogaru, who were born in Italy but are of Romanian descent, through several surgeries in about six months. Without separation, the twins risk dying in early childhood.

There was no indication how long the surgery would take and a report on the twins' condition wasn't planned until Thursday, said Janice Guhl, spokeswoman for University Hospitals' Rainbow Babies & Children's Hospital.

In the daylong procedure Wednesday, surgeons said they would begin at the girls' scalps and slowly make a wedge where the twins' skulls are joined. They plan to remove a rectangular bone flap and reinsert it at the end of the surgery.

The procedure will give neurosurgeons their first real glimpse of the girls' brains. The medical team practiced the procedure on a model designed from images.

How much separation is accomplished Wednesday depends on the complexity of blood vessels, tissue and bone connections.

The girls' parents, the Rev. Alin Dogaru, a Byzantine Catholic priest, and Claudia Dogaru, both 31, have said they view the separation surgeries as the girls' best hope. They arrived in Cleveland on April 6 after 2 1/2 years in Dallas.

Twins born joined at the head — known as craniopagus twins — are rare, occurring in about one in 2.5 million births. The top of Tatiana's head is attached to the back of Anastasia's, and they have never been able to look directly at each other.

Last month, doctors succeeded in establishing independent blood flow in the twins by inserting small coils into veins in their brains. That was viewed as a prerequisite for separation surgery.

Bleeding in these procedures is a major risk. Other potential complications include infection, stroke and a build up of fluid in the brain, doctors say.
