Peanuts for a Peanut Allergy?


It almost seems counterintuitive. With almost 3.3 million people suffering from allergic reactions when they eat or even come in contact with peanuts or tree nuts, almost two-thirds of whom are children, this type of allergy can prove deadly. In fact, last year there were 150 deaths caused by ingesting, either by mouth or through skin contact.

The American Academy of Allergy, Asthma and Immunology Research believes they may have the answer to a peanut allergy: give them peanuts. The dose begins in many instances with one-thousandth of a peanut with gradually increasing amounts. The experiment lasted for over two years and was conducted among 33 children. Powdered forms of peanuts were sprinkled on the child's food (in other words, don't try this experiment at home on your tot) with six children receiving a placebo. (A placebo is how science determines the results of the experiment by administering fake doses with real ones.)

The study, conducted at Duke University and Arkansas Children’s Hospital in Little Rock, found that most of the children who received the powdered form of the peanuts, in gradually increasing doses suffered from no allergic reaction - five of the children did so well they dropped out of the study because of the significant increases in their tolerance for the nut.

Parents should know that there are still no concrete findings on why these children develop this allergy. According to the Cincinnati Center for Eosinophilic Disorders they have looked at numerous possibilities, ruling out a few along the way and being surprised by others. Worries over what a mother had eaten while pregnant were studied. The report concluded that "Notably, cord blood analysis revealed no detectable IgE to peanut indicating in utero exposure was not likely to account for the sensitization. Of further note, maternal dietary factors also had no correlation with peanut allergy. However, there was an association between the duration of breastfeeding and peanut allergy; the significance of this is unclear."

But on the other hand, the study revealed that "there was a strong and statistically significant association between consumption of soy milk or soy formula in the first two years of life and the development of peanut allergy. This consumption typically preceded development of peanut allergy. The association with soy protein exposure and peanut allergy could arise from cross sensitization through common episodes that may prime T cell responses."

Milk allergy was not associated with peanut allergy nor was the use of breast creams, often containing trace elements of peanut oil was also ruled out. But some creams for rashes also contain peanut oil and researchers found that the use of these types of creams was suspect in causing the allergy.

The mystery has yet to be solved. The peanut is actually not a true nut, but a member of the legume family, which includes peas, lentils, soybeans and lima beans. Having a peanut allergy doesn't necessarily mean a person will be allergic to other legumes or nuts because of the varying sensitivity level of the individual to the peanut protein found in different types of nuts and legumes.

So far, after-the-fact treatment of the allergy and avoiding the nut, or traces of the nut in the production of other products is still the best approach in prevention. But the results of this study is promising. But whatever you do, don't try any home treatments not recommended by your child's doctor. But rest assured, the answer to this childhood problem seems close.

Pre-School and Daycare Vaccines: What is Measles?

With the recent refusal of numerous parents to vaccinate their children, most based on the fear that these types of vaccines are a result in the increase in autistic children, measles has begun to rear its ugly (rash-y) head. This might be as dangerous a consequence as refusing to get the vaccine in the first place, a gamble that may have long-lasting effects and possibly even death waiting in the wings

What is measles?

According to the New York Department of Health, it is an "acute, highly contagious viral disease capable of producing epidemics." What is often unknown, is how many people have had the vaccination that prevents this disease from spreading. Because the disease is "usually considered a childhood disease, it can be contracted at any age. The majority of cases are now imported from other countries or linked to imported cases." But that is changing according to Mike Stobe of the Associated Press.

He writes: "Measles cases in the U.S. are at the highest level in more than a decade, with nearly half of those involving children whose parents rejected vaccination, health officials reported Thursday" of last week.

"The number of cases" he continues, "is still small, just 131, but that's only for the first seven months of the year. There were 42 cases for all of last year." It seems to be making its re-emergence via home schooled kids in particular.

The following information comes from the NY Department of Health and is extremely important when making the decision to or not to vaccinate:

"In the first stage, the individual may have a runny nose, cough and a slight fever. The eyes may become reddened and sensitive to light while the fever consistently rises each day. The second stage begins on the third to seventh day and consists of a temperature of 103-105 degrees Fahrenheit and a red blotchy rash lasting four to seven days. The rash usually begins on the face and then spreads over the entire body. Koplik spots (little white spots) may also appear on the gums and inside of the cheeks.

"How soon do symptoms appear?
"Symptoms usually appear in 10-12 days, although they may occur as early as seven or as late as 21 days after exposure.

"When and for how long is a person able to spread measles?
An individual is able to transmit measles from four days prior to and four days after rash onset.

"Does past infection make a person immune?
"Yes. Permanent immunity is acquired after contracting the disease.

"What is the treatment for measles?
"There is no specific treatment for measles.

"What are the complications associated with measles?
"Pneumonia occurs in up to six percent of reported cases and accounts for 60 percent of deaths attributed to measles. Encephalitis (inflammation of the brain) may also occur. Other complications include middle ear infection, diarrhea and convulsions. Measles is more severe in infants and adults.

"How can measles be prevented?
"Anyone born on or after January 1, 1957, who does not have a history of physician-diagnosed measles or serologic confirmation of measles immunity, should receive two doses of MMR (measles, mumps, rubella) vaccine for maximum protection. The first dose should be given at 12-15 months of age. The second dose should be given at four to six years of age (school entry) at the same time as the DTaP and polio booster doses. MMR vaccine is recommended for all measles vaccine doses to provide increased protection against all three vaccine-preventable diseases: measles, mumps and rubella. Measles immunization is required of all children enrolled in schools and pre-kindergarten programs. Since August 1, 1990, college students have also been required to demonstrate immunity against measles."
