Dental & Oral Health - How to keep your child's teeth ...

Written by Julie Revelant

Brushing twice a day should definitely be non-negotiable in your house, especially since experts are seeing more and more kids with cavities.

The problem actually starts with the preschool set. In fact, more than 25 percent of children aged 2 to 5 years old in the United States have tooth decay, according to the Centers for Disease Control and Prevention.

What?s more, pediatric dental disease is the primary reason children visit the emergency room each year, according to the Forsyth Institute.

So what more can you do to make sure your child?s teeth and gums will be healthy throughout his lifetime? Here are five things you can do now:

1. Start dental visits early.

?Early intervention can prevent cavities,? said Dr. Joel H. Berg, president of the American Academy of Pediatric Dentistry. Berg said children should see the dentist by the time they turn one or when the first teeth erupt.

The dentist can make sure your child?s teeth are coming in properly, assess his or her risk for problems later on, and talk about fluoride and the correct way to brush your child?s teeth. Plus, regular visits before age 3 get your child used to being examined, which can allay any fears and make it a positive experience, Berg suggests.

2. Eat healthy.

Even if your child isn?t allowed to eat cookies, sugar?albeit natural?can still show up in formula, milk, juice, fruit and crackers.

Make sure your child is eating a balanced diet and try to avoid sticky or sugary snacks. Offer juice only at mealtime and water in between and never put your baby to bed with a bottle.

3. Care for baby teeth.

Even though baby teeth will eventually fall out, it?s important to take care of them now. Baby teeth hold the place for permanent teeth, are important for speech development, and allow your child to chew nutritious food. Plus, infected baby teeth can cause tooth decay in permanent teeth.

Good Reads: 'purdah' culture in India, born good, finding purpose, a Jedi response

This week's good reads includes a young woman's perspective on India's 'purdah' culture, the morality of babies, on whether a life's purpose brings happiness, and an unusual petition to the White House for building a Death Star.

By Ben Arnoldy,?Staff Writer / January 21, 2013

Female staff members of a luxury hotel exhibit their skills after a 10-day self-defense course initiated by the hotel management and Delhi Police women?s wing in New Delhi, India, Jan. 17, 2013. A brutal rape of a 23-year-old student last month has sparked a national debate about the treatment of women and the inability of Indian law enforcement to protect them.

?My first sense as a young girl of sexual menace came from my Indian grandfather. Let me be clear: He never even remotely sexually threatened or molested me. But he made sure I knew that the world in which I, a girl, was growing up was innately perilous to women.?

So starts an illuminating first-person recollection of an American learning the rules of purdah ? or concealment of women from men ? on visits to relatives back in India. Her grandfather upbraided her for uppity talk and anything but simple dress, to teach her that the more invisible she was, the more safe she would be.

Mira Kamdar, writing on the Asia Society website, connects these lessons to the recent gang rape of a young woman on a bus in Delhi: ?It is clear ... that a purdah mentality still dogs Indian society. A woman who can be seen is seen as a woman available for violation.? But, at the same time, ?[r]apid modernization and urbanization in India have made women, especially young women, visible as never before.?

Babies born good

Parents, it turns out that your bundles of joy could also be described as budding altruists. Writing for the Smithsonian magazine, Abigail Tucker writes on a heartwarming new area of research that?s finding babies showing preferences for ?good guys? over ?bad guys? and a proclivity to help and care for others.

?These findings may seem counterintuitive to anyone who has seen toddlers pull hair in a playground tunnel or pistol-whip one another with a plastic triceratops,? notes Ms. Tucker.

But a series of cleverly designed experiments at Yale and Harvard universities are seeing an orientation toward the good long before parents would seem to have had much chance to shape behavior.

The eureka moment for one researcher came while passing a ball back and forth with a toddler. The ball got away from the scientist, and rather than get it, he faked an inability to reach it. Seeing his struggle, the toddler got up to retrieve it for him. Other experiments involved puppet shows in which one color puppet is shown helping or hindering another. Eye-tracking tests found infants as young as 3 months old preferring the helper.?

Life, liberty, and the pursuit of meaning

Whether we are born with it, or taught it, altruism looks to be key to our well-being as adults.

Emily Esfahani Smith, writing for The Atlantic, highlights a new psychological study that suggests ?a meaningful life and happy life overlap in certain ways, but are ultimately very different.? Researchers interviewing 400 Americans found meaning in life to be tied up with being a ?giver,? while happiness was more linked with being a ?taker.? Meaning is also found in contemplating the future and the past, while happiness is fixated on the present ? and is consequently more fleeting.

From the nation?s foundational documents to the self-help aisles of bookstores, Americans are famously in pursuit of happiness. But that?s something of a mug?s game: ?Research has shown that having purpose and meaning in life increases overall well-being and life satisfaction, improves mental and physical health, enhances resiliency, enhances self-esteem, and decreases the chances of depression. On top of that, the single-minded pursuit of happiness is ironically leaving people less happy, according to recent research,? Ms. Smith writes.

The magazine goes on to cite data that roughly 40 percent of Americans have not found a ?satisfying life purpose.?

There will be no Death Star

A group of Internet pranksters raised the 25,000-plus signatures needed to get a response from the White House on their petition to have the US build a Death Star. The White House, to no one?s surprise, replied that the country would not be building the moon-shaped space station from the ?Star Wars? films that could blast planets into space dust. But the wording of the response, glorious it was.

?Why would we spend countless taxpayer dollars? ? $850,000,000,000,000,000, according to one study ? ?on a Death Star with a fundamental flaw that can be exploited by a one-man starship?? wrote Paul Shawcross, chief of the Science and Space Budget at the White House Office of Management and Budget, and arguably the best communicator to emerge from the intersection of space science, accounting, and the federal government.

This smooth-talking Jedi then went on to highlight the gee-whiz stuff the government and the private sector are doing in space.
?[W]e?ve got two spacecraft leaving the Solar System and we?re building a probe that will fly to the exterior layers of the Sun. We are discovering hundreds of new planets in other star systems and building a much more powerful successor to the Hubble Space Telescope that will see back to the early days of the universe.?

In other news, the White House has just upped the signature threshold for a response to 100,000.

EU proposal to protect bees stirs hornets' nest

(AP) ? An attempt to protect Europe's bee population has kicked up a hornets' nest.

On Thursday, the EU's commissioner for health and consumer policy, Tonio Borg, proposed to restrict the use of three pesticides ? called nenicotinoids ? to crops to which bees are not attracted.

The three pesticides were clothianidin, imidacloprid and thiametoxam; the crops from which they would be banned include sunflowers, rapeseed, cotton and maize. The policy would take effect July 1 for the EU's 27 nations and be reviewed after two years.

But while environmentalists welcomed Borg's proposal as an important first step, Borg's spokesman, Frederic Vincent, confirmed that some countries reacted unenthusiastically, preferring further study to immediate action. He declined to identify them.

Marco Contiero of the environmental group Greenpeace said Britain was firmly opposed, and Germany and Spain were either opposed or wanted more time to consider.

Luis Morago of the advocacy group Avaaz, meanwhile, condemned what he called "spurious" British and German opposition and said 2.2 million people had signed an Internet petition calling for a comprehensive ban on the pesticides.

Beekeepers have reported an unusual decline in bees over the past decade, particularly in Western Europe, the European Food Safety Authority says. Bees are critically important to the environment, sustaining biodiversity by providing pollination for a wide range of crops and wild plants ? including most of the food crops in Europe, it says.

"This is the first time that the EU has recognized that the demise of bees has a perpetrator: pesticides," Morago said. "The two-year suspension on pesticides could mark a tipping point in the battle to stop the chemical Armageddon for bees, but it does not go far enough."

Matthias Wuethrich of Greenpeace agreed that more needed to be done to save the bees.

"A ban on a few hazardous pesticides is only a very limited safeguard," Wuethrich said. "The disappearance of bees is just a symptom of a failed agricultural system based on the intensive use of chemicals, serving the interest of powerful corporations like Bayer and Syngenta."

He said the solution was a "paradigm shift to sustainable agriculture and modern eco-farming practices."

People having stroke should get therapy within 60 minutes of hospital arrival

Jan. 31, 2013 ? People having an ischemic stroke should receive clot-dissolving therapy -- if appropriate -- within 60 minutes of arriving at the hospital, according to new American Stroke Association guidelines published in the American Heart Association journal Stroke.

Ischemic stroke, which accounts for nine in 10 strokes, is caused by a blood clot in the arteries leading to the brain. Calling 9-1-1 immediately after recognizing any of the warning signs of stroke -- and getting to a stroke center as fast as possible -- are still the most important steps for optimal stroke care.

During an acute stroke, physicians must quickly evaluate and diagnose the patient as soon as possible to determine if patients are eligible to receive the clot-dissolving drug recombinant tissue plasminogen activator (tPA), which must be given 4.5 hours within hours of symptom onset. The goal is to minimize "door to needle" time which provides the patient with the best opportunity for benefit from the treatment.

"tPA can now be considered for a larger group of patients, including some who present up to 4.5 hours from stroke onset," said Edward Jauch, M.D., lead author of the guidelines and director of the Division of Emergency Medicine at the Medical University of South Carolina.

The new guidelines recommend integrating regional networks of comprehensive stroke centers (which offer 24/7, highly specialized treatment for all types of stroke); primary stroke centers (which provide 24/7 specialized care mainly for ischemic stroke); and acute stroke-ready hospitals (which can evaluate and treat most strokes but lack highly specialized capabilities), and community hospitals.

"This is the first time we've brought these healthcare elements together --, including community hospitals which may lack onsite stroke expertise, which reflects the emerging role of telemedicine in these hospitals," Jauch said.

Among other major revisions to the guidelines, if feasible, patients should be rapidly transferred to the closest available certified primary care stroke center or comprehensive stroke center, which might involve air medical transport. "However, for patients brought to hospitals without specialized stroke expertise, telemedicine can provide real-time access to expertise," Jauch said. "If such a hospital partners with a primary or comprehensive stroke center and uses telemedicine, early treatment decisions can be made for patients. If the patient had to be transferred before administering some therapies, it would be too late."

Other key recommendations in the new guidelines include:

  • Multidisciplinary quality improvement (QI) committees should be created within hospitals to review and monitor stroke care quality. "We now have dozens of studies showing the benefit of QI programs," Jauch said.
  • Recently introduced stent retrievers could potentially remove large blood clots more completely and quickly than tPA. But the devices shouldn't be a substitute for intravenous tPA and should only be used in clinical studies to determine if they improve patient outcomes.

F.A.S.T. is an easy way to remember the sudden signs of a stroke:

  • Face drooping: Does one side of the face droop or is it numb?
  • Arm weakness: Is one arm weak or numb?
  • Speech difficulty: Is speech slurred, are you unable to speak, or are you hard to understand?
  • Time to call 9-1-1: If you have any of these symptoms, even if the symptoms go away, call 9-1-1 and get to the hospital immediately.

Suicide bomber attacks Pakistani mosque, 18 dead

PESHAWAR, Pakistan (AP) ? A suicide bomber detonated his explosives outside a Shiite mosque in northwestern Pakistan as worshippers were leaving Friday prayers, killing at least 18 people and wounding over 30 in the latest apparent sectarian attack in the country, police said.

Shiite Muslims in Pakistan have increasingly been targeted by radical Sunnis who consider them heretics, and 2012 was the bloodiest year for the minority sect in the country's history.

There were conflicting reports about the exact number of dead in the attack on the mosque in the town of Hangu in Khyber Pakhtunkhwa province.

Police officer Naeem Khan said 18 people were killed in the bombing, while Hangu police chief Mian Mohammad Saeed put the death toll at 20. Both police officers said over 30 people were wounded, many of them critically.

Most of the dead and wounded were Shiites, but some of the casualties were also from the country's majority sect since there is a Sunni mosque nearby, said Khan.

Hangu has experienced conflict in the past between the Sunni and Shiite communities that live in the town. Both sides have attacked each other's shops and burned them.

The worst sectarian violence in Pakistan in recent years has been in southwestern Baluchistan province, which has the largest concentration of Shiites in the country. A twin bombing last month at a billiards hall in the provincial capital, Quetta, killed 86 people, most of them Shiites.

According to Human Rights Watch, more than 400 Shiites were killed in targeted attacks in Pakistan in 2012, including over 120 in Baluchistan.

Gas promises bumper black hole 'weigh-in'

Friday, February 1, 2013

A new way of measuring the mass of supermassive black holes could revolutionise our understanding of how they form and help to shape galaxies.

The technique, developed by a team including Oxford University scientists, can spot the telltale tracer of carbon monoxide within the cloud of gas (mostly hydrogen) circling a supermassive black hole at the centre of a distant galaxy. By detecting the velocity of the spinning gas they are able to 'weigh' (determine the mass) of the black hole.

Detailed information on supermassive black holes, thought to be at the heart of most galaxies, is scarce: it has taken 15 years to measure the mass of just 60. The problem is that most other supermassive black holes are too far away to examine properly even with the Hubble Space Telescope.

The new method, when combined with new telescopes such as ALMA (Attacama Large Millimetre/submillimetre Array), promises to extend this black hole 'weigh-in' to thousands of distant galaxies. It will also enable the study of black holes in spiral galaxies (similar to our own Milky Way), which are hard to target using currently available techniques.

A report of the research is published in this week's Nature.

The team demonstrated the new technique on the supermassive black hole at the centre of a galaxy, NGC 4526, in the constellation of Virgo. NGC 4526 was chosen as a test because it has been widely studied but the team believe the technique will work on a wide range of different galaxies.

Tim Davis of the European Southern Observatory, lead author of the paper, said: 'We observed carbon monoxide molecules in the galaxy we were monitoring using the Combined Array for Research in Millimetre-wave Astronomy (CARMA) telescope. With its super-sharp images we were able to zoom right into the centre of the galaxy and observe the gas whizzing around the black hole. This gas moves at a speed which is determined by the black-hole's mass, and the distance from it. By measuring the velocity of the gas at each position, we can measure the mass of the black hole.'

Dr Michele Cappellari of Oxford University's Department of Physics, an author of the paper, said: 'Because of the limitations of existing telescopes and techniques we had run out of galaxies with supermassive black holes to observe. Now with this new technique and telescopes like ALMA we will be able to examine the relationship between thousands of more distant galaxies and their black holes giving us an insight into how galaxies and black holes co-evolve. Importantly our 'weigh-in' technique will work for all kinds of galaxies, including spiral galaxies which are particularly difficult to observe with previous techniques.'

Dr Martin Bureau of Oxford University's Department of Physics, an author of the paper, said: 'The ALMA telescope is now in the final stages of construction and our team is currently bidding for time to use it for our black hole survey. If all goes according to plan we could begin our survey by the end of this year.'
