Doctors Link Gene to Childhood Asthma

US researchers discover that a defective gene appears to contribute to childhood asthma, a finding that could lead to a better understanding of allergies.
The Scoop

In what looks to be a true medical breakthrough, a team of researchers from Children’s Hospital of Philadelphia believe they have pinpointed the underlying cause of most cases of childhood asthma: a defective gene that triggers the body’s immune system to overreact to certain allergens.Doctors Link Gene to Childhood Asthma

The study,in the New England Journal of Medicine, tested DNA samples from more than 8,000 people from North America, Europe, and Africa, some of whom had persistent childhood asthma. Allergies were involved in about 85 percent of childhood asthma cases and between 80 to 90 percent of those children had the defective gene.

“The cells that express that gene decide what happens when allergens, viruses, and foreign materials come into the body,” said Dr. Hakon Hakonarson, study lead author, in an interview with ABC News. In children with the gene defect, Hakonarson speculates, immune system cells go awry and chronically produce asthmatic reactions.
For Children

Researchers believe their finding may go a long way towards developing a better understanding of why some children develop asthma—and one day creating a gene-based treatment for the condition.

“Other asthma-related genes remain to be discovered, but finding a way to target this common gene variant could benefit large numbers of children,” noted Hakonarson.

According to the Asthma and Allergy Foundation of America, about 20 million Americans have asthma—a disease of the lungs in which the airways become blocked or narrowed causing breathing difficulty.

Teething

Ouch! Teething is never fun for babies or new parents. Follow our tips to help take the bite out of teething woes.

All Smiles: Tips for Easing Teething

Your baby has been fussing a bit more than usual the past couple days, and you notice that you’re suddenly awash in drool. Could your little one be teething?

First Teeth

Beginning anywhere from ages four to six months, your baby will likely get her first new tooth. The first chompers to show are usually the two front bottom teeth, called the central incisors. The four upper front teeth, also incisors, are normally the next to erupt. The remaining teeth, including molars and eyeteeth, will break through periodically until your child is about two and one-half years old and has 20 teeth altogether.

Teething Symptoms

Expect your baby to experience some discomfort and side effects during teething. While many people believe that a host of symptoms are associated with teething, the most widely recognized by doctors are:

  • irritability
  • restlessness or difficulty sleeping
  • increased saliva, drooling
  • a desire to chew on everything within grasping distance.

Signs of teething in a baby’s mouth can also include swollen, tender gums where a new tooth is coming through. These symptoms may begin three to four days before a tooth pushes through and last two to three days after it makes its appearance.

Teething Remedies

If your baby is showing discomfort from teething, there are things you can do to help him feel better:

  • Try simple distractions such as cuddling, rocking, or walking around with your baby.
  • Use your fingers to massage irritated or swollen gums for two-minute intervals as often as necessary.
  • Wrap a piece of ice in a wet cloth and rub the spot. Be careful that the ice doesn’t slip out of the cloth and into baby’s mouth, since this is a choking hazard.
  • Allow your child to massage her own gums by gnawing on a teething ring. A chilled (but not frozen) teething ring or wet washcloth can be extremely comforting. Avoid using teethers once baby’s teeth appear, since the teeth could puncture a soft teething ring.
  • Offer chilled baby foods such as applesauce or pureed fruit to a child already accustomed to eating solids. Do not use popsicles, frozen bananas, carrots, or any other non-pureed food as these pose a choking hazard.
  • If your baby has excessive drooling, avoid dehydration by replacing lost fluids with diluted juice or water. You will also want to keep your baby’s face and clothes dry to prevent rashes or irritation. A bib may help protect clothing from wetness.
  • If the above methods don’t seem to work, ask your child’s physician about using medicated ointments such as Zilactin Baby medicated gel, Hyland’s Teething Gel or Tablets, Baby Orajel Teething Pain Medicine, or Baby Anbesol.
  • If nothing seems to work, consult with your pediatrician about trying systemic analgesics such as infant acetaminophen or ibuprofen. Do not use baby aspirin, which has been linked to Reye’s syndrome, a serious and potentially life-threatening disease.

As with so many aspects of parenting, teething can be a difficult stage for you and your baby to endure. But remember, this too shall pass and before you know it, your little one will have a beautiful, toothy grin.

Baby Colic Symptoms And Remedies

Do you wonder if your baby might have colic? How to identify and minimize baby colic symptoms plus remedies. Learn why colic’s causes are so mysterious an d how to tell if your infant has colic.

Colic is a common problem found in six to 13 percent of all infants. Colicky infants cry for an average of four hours a day, enough to irritate even the most loving parent. And persistent, inconsolable crying, especially in the evening, is the hallmark of colic.

Does Your Baby Have Colic?

If your little one is often inconsolable, and cries for long stretches of time (often during the evening hours), be sure to make an appointment with your family pediatrician. You and your child’s doctor need to make sure that there is no medical cause for your baby’s colic. While medical causes for colic are rare, if they are present, they should be treated as soon as possible.

To determine if there is an underlying cause for your baby’s crying, discuss the following questions with your pediatrician:

  • Is there a hernia or evidence of some other medical problem?
  • Is your child stooling too much or too little?
  • Is there any blood or mucous in the stool?
  • Is your child eating too much or too little?
  • Are the stools abnormally colored (clay-colored, frothy or very green, tar black)?
  • Is weight gain below what would be expected?

If the answer to any of these questions is “yes,” further investigation by your doctor should be pursued.

Minimizing Colic’s Symptoms

There is no agreement about whether breastfed babies have more or less colic than bottlefed babies. And there is also controversy about whether foods eaten by the mother or infant contribute to colic. In addition, there is little scientific evidence that any treatment reduces the symptoms.

So, what is a parent to do? The answer for baby colic symptoms and remedies are different for different babies. Unfortunately, treating colic involves a certain amount of trial and error. Some common suggestions gleaned from my own experience, and the advice of other doctors and parents, include a variety of options.

Here are some of the more popular ways to try and soothe your colicky baby:

  • If you are breastfeeding, consider eliminating cabbage and other cruciferous vegetables, milk products, caffeine, onions, chocolate, and garlic from your diet. Some studies have suggested that these foods increase the risk of colic. (If this makes a difference, mom should add those foods back into her diet one at a time to identify the offending food or foods.)
  • If you are formula feeding your baby, ask your pediatrician about changing to a non cow-milk–based formula. Although there is no data to support changing formulas, it occasionally does help.
  • Motion is often helpful in soothing fussy babies. Rock your baby or place her in a body carrier.
  • If breastfeeding is well established, consider a pacifier.
  • Burp your baby often—including after sucking on a pacifier and especially after feeding. Babies can swallow a significant amount of air that causes gas.
  • Reduce stimulation in your baby’s environment and offer her a relaxing, fuss-free space to unwind.
  • For little ones who don’t seem to find solace in a completely quiet room, try employing the use of “static” sound, such as a hairdryer, vacuum cleaner, or white noise machine. Some parents find that nondescript background noise can be quite soothing for their fussy baby.
  • If you don’t already swaddle your baby, try wrapping her up in a cozy blanket.
  • Increase the amount of nighttime feedings.
  • Ask your pediatrician if a prescription medication may be a good option for you and your baby. (NOTE: The only drug shown to be effective, dicyclomine, does carry about a five-percent risk of significant side effects.)
  • Ask your pediatrician about over-the-counter Simethicone products or “grip water” products; these may help in some cases.

Since colic is almost always a self-limited problem, treatment should not involve risk. Be sure to check with your pediatrician for treatment suggestions, and always get your doctor involved if the problem worsens or there is a complication from a potential remedy.

And remember, most babies outgrow colic. Although it may appear that the end is nowhere in sight, don’t forget the popular adage used by so many pediatricians: “This too shall pass!”

Thumb Sucking

http://4.bp.blogspot.com/_3vQGNkSWIaY/SdDYtNJlqtI/AAAAAAAABNA/P-9yx1MPDDY/s320/sucking-thumb_50.jpg

Some do it in the womb, some do it right after birth, some never do it at all. Whichever the case, babies clearly start life with a natural urge to suck. Almost all babies plop a thumb, fist, finger, or pacifier in their mouth at some point during the first year. In fact, a recent study on the use of sleep aids from the University of California, Davis, found that almost all infants used something to help them at bedtime. Three-month-olds preferred thumbs, fingers, or hands, whereas 6-month-olds went for soft objects such as pacifiers. Experts say there are benefits from this “nonnutritive sucking”, including the following:

  • It satisfies a baby’s normal sucking reflex.
  • Sucking creates a soothing effect, which helps lull a child to sleep, or calms her when she’s upset.
  • Using their mouths is the primary way infants learn about the world.

Gayle Flynn, a New York City mother of three, notes that while her two-month-old, Logan, puts his fist in his mouth when he’s hungry or cranky, her oldest son Ryan never used anything, whereas daughter Hilary liked a pacifier. “It became a nightly ritual which helped her sleep,” says Flynn.

Pacifier vs. Thumb
When it comes to a pacifier versus a thumb, it seems pediatricians are divided on which is better for your child. Some say pacifiers are less likely to lead to dental problems since pacifiers are more flexible, exerting less pressure on the mouth, and their use can often be stopped earlier. Meanwhile, some studies suggest that babies who use pacifiers are more likely to get ear infections, but that association appears to be negligible if the pacifier is restricted to bedtime. Other research links pacifier use in the first few months to decreased long-term breastfeeding. Also, some babies may develop nipple confusion if a pacifier is introduced before breastfeeding is established.

As for thumbs, experts say babies who use thumb or fingers may be more independent because digits won’t ever get lost or fall out of the crib.

When to End?


Whichever your infant prefers, if he’s still sucking at age 2 you might want to begin to break him of the habit, or at least limit how often he does it. For years doctors have touted thumb or pacifier habits as fine until around age 5, but a new study in the December issue of The Journal of the American Dental Association suggests that if the practice continues beyond age 2, a child’s bite may be affected, causing misalignment of the teeth. Dr. Mary J. Hayes, a pediatric dentist  in Chicago points out that nonnutritive sucking can also lead to speech problems like lisping.

Whether or not your child is affected depends largely on the frequency or intensity of her habit. “Some kids just occasionally place the thumb or pacifier in their mouth, but others suck more often or more intensely,” she says, and those are the ones to watch. A pediatric dentist can help you determine if your child’s sucking is causing problems.

Key nutrients for a healthy pregnancy

Being that March is National Nutrition Month, we’ve been looking at various healthy eating tips. Although it is important to focus on healthy foods and beverages, another nutritional area to be aware of during pregnancy includes vitamins.

There are some important key nutrients your body needs for a healthy pregnancy and baby…

Folic acid: Folic acid is one of the most important pregnancy nutrients you need. Folic acid can greatly reduce the risk of birth defects that affect the spinal cord. The American Diabetes Association (ADA) recommends that all pregnant women get 600 micrograms of folic acid daily.

Iron: Iron deficiency anemia is a very real pregnancy risk. If you’re pregnant you need at least 27 milligrams of iron a day. High-iron foods include spinach, kale, leafy greens, beans, fortified cereals, red meat, chicken and fish.

Calcium: During pregnancy you need plenty of calcium for the healthy development of a baby’s teeth, bones, heart, nerves and muscles. If you don’t consume enough calcium, your baby will take the calcium he needs from your bones, leaving you vulnerable to osteoporosis. You need at least 1,000 milligrams of calcium a day before, during and after pregnancy.

Most pregnant women do need to take a prenatal vitamin and sometimes additional mineral supplements because it’s very hard to get all the key nutrients you need from simply eating food. Discuss vitamin and mineral options with your midwife or doctor.
