Is Your Teen Lying to You?

ByGina Shaw
WebMD Feature Reviewed byHansa D. Bhargava, MD

Trying to figure out if your teen is lying to you can be tricky.

Researchers who study lying and truth-telling among children have found that parents often can't tell when their child is lying.

Since trying to catch your teen in a lie is probably a waste of time, family therapists say you're better off using a different tactic: Make it easier for your teen to tell you the truth.

"Punishing for lying just teaches children to be better liars," says psychologist Laura Markham, PhD, author of Peaceful Parent, Happy Kids.

Ideally, you would help your child get comfortable telling you the truth from an early age. But if your child is already a teen, it's not too late to show her that she can be honest with you, if you’re ready to work at it.

“It can take a year of consistently shifting the way you approach lying for your teenager to trust you enough to tell the truth,” says Joe Broome, MA, a family therapist in Renton, Wash.

To start rebuilding the relationship:

Spend time with your teen every day. It doesn't have to be a major event. Just share part of your day with them, one on one. Markham suggests doing something that your teen enjoys, such as getting a manicure or playing video games.   Expect them to test you. "They won't immediately confide in you," Markham says. "They might tell you that their friend Robbie got in trouble because of XYZ. Robbie's a test. If you fly off the handle and say ‘Oh no, do Robbie's parents know about this?' they'll never tell you anything again. But if instead you say, ‘Wow, Robbie must have been so upset. I wonder how he felt. I wonder if lots of kids do this,' you'll encourage him to talk more." Don't overreact. When your teen tells you something that freaks you out, stop and breathe. Bite your tongue if you have to. "When your teen does start confiding in you, it's even more important to really regulate your emotions," Markham says. That doesn't mean that there aren't consequences. You need to clearly define for your teen, ahead of time, how you'll respond if they lie and how much you value honesty. Then you'll need to follow through. Just do it calmly, without flying off the handle. Help your teen problem-solve. Instead of telling him what you think about what he's just confided in you, ask him what he thinks. "If your teenager tells you that other kids are drinking and driving, the impulse is to freak out," Markham says. But taking a simple "Just say no!" approach shuts down the conversation. "Instead, you can say something like, ‘It must be so hard and scary when someone who's been drinking wants you to get in the car. It would be embarrassing to be the one to say something, wouldn't it? What can we do so you're not in that situation?'"

Every parent wants a silver bullet to deal with lying. But there is no such thing.  "It's about building a relationship based on trust," Broome says. "You, as the parent, have to take the lead in that."

Scientists Working Toward Pill for Celiac Disease

ByBrenda Goodman, MA
WebMD Health News Reviewed byBrunilda Nazario, MD

Dec. 21, 2012 -- Scientists say they’re working on a pill that may one day help people with celiac disease tolerate foods that contain gluten, a protein that is found in wheat and other grains.

“It would be pretty much like the Lactaid pill,” says researcher Justin B. Siegel, PhD, an assistant professor of biochemistry and molecular medicine, and chemistry, at the University of California at Davis, referring to a product that helps people who get an upset stomach when they drink or eat dairy foods.

In a study published in the Journal of the American Chemical Society, researchers describe testing a new enzyme called KumaMax that breaks down gluten.

In a test tube, the enzyme -- which was discovered in bacteria that live in Japanese hot springs and modified slightly in the lab -- dismantled more than 95% of a protein component that’s thought to trigger celiac disease.

The enzyme hasn’t yet been tested in people. Researchers say that’s the next step.

Gluten-Free Diet: Getting Started

Other Research Also Under Way

They aren’t the only group working on this kind of a treatment for celiac disease, says Joseph A. Murray, MD, a gastroenterologist and celiac disease specialist at the Mayo Clinic in Rochester, Minn.

Murray recently reviewed experimental approaches for treating celiac disease, but he was not involved in the research.

A company called Alvine pharmaceuticals is also testing an enzyme-based pill. Early results show that people with celiac disease who got the experimental pill had less damage to their small intestine after eating food containing gluten compared to those who got a placebo. But larger studies are needed to confirm those results.

Even if the pills work, they “won’t be a passport to eating gluten with impunity,” says Murray.

“It probably will only reduce your sensitivity to gluten, it won’t block it. Instead of taking in no gluten, you might be able to take in the equivalent of half a slice of bread and get away with it. It’s very unlikely that you could eat a pizza and get away with it,” says Murray, who has been a paid consultant for Alvine.

“It may make life better, but it’s really an adjunct to the continued effort to be gluten-free.”

Tough to Avoid Wrong Foods

In celiac disease, gluten proteins trigger an immune system attack on the lining of the gut. Over time, damage prevents the absorption of important nutrients and may lead to vitamin and mineral deficiencies that cause hair loss, depression, and brittle bones.

Currently, the only treatment for celiac disease is to avoid foods that contain gluten.

Murray says many of his patients find that despite their best efforts to avoid wheat, they end up eating some at least once a month because it turns up in foods they didn’t prepare themselves or because they can’t say no to a favorite treat.

“It’s very difficult to avoid. We’re in a very gluten-rich environment,” Murray says.

FDA Approves Tamiflu for Infants

ByJennifer Warner
WebMD Health News Reviewed byBrunilda Nazario, MD

Dec. 21, 2012 -- Children as young as 2 weeks old may now be treated for the flu with Tamiflu.

The FDA expanded its approval today for Tamiflu to include infants under age 1 who have had symptoms of the flu, such as stuffy nose, cough, sore throat, fever, and body aches, for no longer than two days.

It is not approved to prevent flu infection in this age group.

Tamiflu is now the only drug approved to treat the flu in children under age 1, who are at higher risk of developing complications of the flu.

Until now, Tamiflu was approved to treat the flu in adults and children ages 1 year and older who have had symptoms for less than two days. The drug is also approved to prevent flu infection in children and adults over 1 year of age.

Correct Dosing for Infants Essential

FDA officials say there is a fixed dosing schedule for children and adults over age 1, but dosing for children under 1 year old must be calculated for each infant according to their weight.

Children under age 1 should receive 3 milligrams of Tamiflu per kilogram of body weight twice daily for five days. This smaller dose requires a different dispenser than what currently comes in the Tamiflu package.

“Pharmacists must provide the proper dispenser when filling a prescription so parents can measure and administer the correct dose to their children,” Edward Cox, MD, MPH, director of the Office of Antimicrobial Products in the FDA’s Center for Drug Evaluation and Research, said in a news release. “Parents and pediatricians must make sure children receive only the amount of Tamiflu appropriate for their weight.”

Infants at Risk for Flu Complications

According to the CDC, children younger than 2 years old are especially vulnerable to developing complications from the flu. Infants 6 months of age and younger have the highest rates of hospitalization for the flu.

The FDA based its approval of Tamiflu for children under age 1 on data from previous studies in adults and older children.

Two new safety studies in 135 children under 1 year old with confirmed cases of the flu also showed the safety profile in infants was consistent with that found among older children and adults.

The most common side effect in these studies was vomiting and diarrhea.

Rare cases of severe rash, skin reactions, hallucinations, delirium, and abnormal behavior have been reported with use of Tamiflu but were not found in these new safety studies.

How Do Sleeping Pills Really Work?

Study Says It's Partly Becasue You Think They Do BySalynn Boyles
WebMD Health News Reviewed byBrunilda Nazario, MD

Dec. 20, 2012 -- The most widely prescribed sleeping pills do help people get to sleep, but maybe not only because of the medicine, a new study suggests.

When researchers combined studies of some of the newer prescription sleep drugs, they concluded that the drugs owe about half their benefits to a placebo effect.

But at least one sleep expert disagrees with that conclusion.

Jobs That Wreck Your Sleep

Benefits Small, Study Finds

The drugs included in the study were the sleep aids Ambien, Lunesta, and Sonata and their generic versions.

The researchers conclude that these drugs improved people's ability to fall asleep compared to a placebo; however, the size of the effect was small.

They add that the risk of side effects and the potential for addiction need to be weighed  when considering using these medications for treating insomnia.  

Side effects of sleeping pills can include memory loss, daytime sleepiness, and increased risk of falls, and researchers say the drugs may be especially risky for older patients.  

But a sleep specialist says the study does little to convince him that the drugs -- used by millions of people worldwide -- are less effective than studies suggest.

“The fact is that it is difficult to measure the effectiveness of sleep medications in studies. Patients take them and they either work or they don’t.”

“I don’t see how these researchers can come to the conclusion that 50% of the effect of these sleeping pills are due to the placebo effect,” says David Volpi, MD, of the sleep disorders division of Lenox Hill Hospital in New York.

Sleep Aid Helps Users Fall Asleep Faster

The new analysis, published in BMJ, was a collaborative effort by scientists from the University of Lincoln in the U.K., Harvard University, and the University of Connecticut.

It included data from 13 trials submitted by pharmaceutical companies to the FDA for approval of eszopiclone (Lunesta), zaleplon (Sonata), and zolpidem (Ambien).

The studies focused on the time it took to fall asleep after taking the drug.

The new analysis shows that sleeping pill users fell asleep about 22 minutes faster than non-users. Those on placebo fell asleep after 42 minutes.

According to researcher A. Niroshan Siriwardena, MD, PhD, one of the major limitations of studies submitted to the FDA is that they failed to measure some of the most troubling issues associated with sleep disturbances including total sleep time, waking after falling asleep, and daytime sleepiness.

“Because the studies didn’t measure these things, we cannot say whether these drugs are useful for improving these outcomes,” he says.

Nondrug Sleep Treatments Effective

Volpi says prescription sleeping pills are often used by patients for much longer than they were originally intended.

These drugs are overprescribed and patients stay on them too long, he says. “It’s not unusual to see patients who have been on them for years.”

Siriwardena and Volpi also agree that other types of sleep treatments, such as talk therapy, are underutilized and could be used to help many more patients with sleep issues.

“There are so many things you can try for sleep problems, and cognitive behavioral therapy is one of the best things patients can do to get off of these medication,” Volpi says says.

The manufacturer of Ambien was contacted but declined to comment. The makers of Lunesta and Sonata were contacted but did not respond before publication.
