Recent research on the prevention of childhood allergies will paralyze parents or completely eliminate them.
Finding out: the sucking of your child's pacifier for cleaning can mean that a little less Olivia or Mila will less likely develop allergies.
"The microbes that a child exposes in their early childhood can influence the development of the immune system," said Dr. Eliane Abou-Jaoude, allergic and immunological associate Henry Ford Health System in Detroit and lead author of the new study. In this case, these beneficial microbes appear to come from the mother's mouth.
Abou-Jaoude and colleagues watched for a year and a half after the birth of 128 new mothers, who occasionally wondered how they cleaned their baby pets.
Of the 74 children infants were using, most were washed by hand; 41 percent made a step forward with sterilization of devices. But 12 percent simply released them into their mouths and purged them.
Researchers in the series of blood tests found that babies had lower IgE levels when they were 10 months old. People who have higher IgE values are generally more prone to allergies, asthma, and eczema.
Some children in the study were already at increased risk because of their family history. Approximately 18 percent of mothers had asthma, and about 8 percent had eczema.
Research does not prove that sucking on a baby dude prevents allergies. "It was not a causal study," said Abou-Jaoude. "We can not say that these children will not develop allergies later. We only have IgE values up to 18 months old."
The research team plans to monitor families in the coming years to determine whether any child will eventually diagnose an allergy. Current research will be presented at a meeting of the American College of Allergy, Asthma and Immunology.
Not all bacteria are bad
The findings show that exposure to mammary bacteria in early childhood can be a very good thing. During childbirth, children are exposed to important bacteria when delivered through the birth canal. Last year the study showed that mothers transmit healthy bacteria to infants through breast milk. And the Swedish study in 2013 found infants whose parents tried to cleanse their dads three times less likely to have eczema as long as they were little ones.
But this does not mean that parents should begin to actively expose their babies to saliva – their own or anyone else.
"Saliva is a very versatile tool," said Whasun "Sun" Oh Chung, a research professor at the Washington School of Dentistry University. It examines how the body distinguishes good bacteria from bad bacteria. He emphasizes that saliva can also transmit potentially dangerous bacteria and causing bacteria. "We do not have enough data to see if the benefits (these practices) outweigh the damage," she said.
Abou-Jaoude agrees. "We are not talking to the elderly to clean the baby's sucker by sucking on the pacifiers. Bad bacteria can get the parent to suck on a cunt and then hand it over to his child and reveal them to other infections."
Still, experts say that such research shows that most children do not need to be educated in an extremely hygienic environment.
"The variety of bacteria in your body, in your mouth and on your skin is probably good, especially in a child whose immune system is developing," Dr. Wendy Sue Swanson, a pediatrician at the Child Seattle Hospital.
"Let them play in dirt," she said. "In their early life, give them food and allow them to explore the world in a way that we once did."
