Many expectant parents are wary of all the recommended vaccines their newborns are supposed to get in the first hours, days and even the first couple of years, believing that too many vaccines too soon may increase their child's risk for autism.
A new study published in the Journal of Pediatrics Friday may put them at ease. Researchers found no association between autism and the number of vaccines a child gets in one day or during the first two years of the current vaccine schedule.
The research was led by Dr. Frank DeStefano, director of the Immunization Safety Office at the Centers for Disease Control and Prevention. Together with two colleagues, DeStefano and his team collected data on 256 children with autism spectrum disorder (ASD) and 752 children who did not have autism. The children were all born between 1994 and 1999 and were all continuously enrolled in one of three managed-care organizations through their second birthday. FULL POST

In Europe, some allergy sufferers are given sublingual immunotherapy, or allergy drops, to treat their symptoms. These tiny drops of purified allergens - such as pollen or dust mites - are placed under the tongue as an alternative to weekly allergy shots. The drops work like a vaccine, slowly increasing the body's tolerance to the allergen.
The Food and Drug Administration has yet not approved these drops for use in the United States, but new evidence published this week by the Journal of the American Medical Association could pave the way for American pharmaceutical companies.
"There is a tremendous interest in this treatment," said Dr. Clifford Bassett, medical director of Allergy and Asthma Care of New York. "As such there have been and are currently clinical trials underway by various companies looking to try to get an approval and come to the U.S. market in the years ahead."
Dr. Sandra Lin from the Johns Hopkins University School of Medicine and her colleagues reviewed 63 studies to analyze the effectiveness of allergy drops.

The virus causing your cold sore may put you at risk for something more insidious: Lower cognitive abilities.
In a study of 1,625 people, researchers at Columbia University measured specific antibodies to common infectious agents in each person's blood, and using this information, created an "infectious burden index." Participants higher on the infectious burden index were more likely to have worse cognition, or cognitive abilities.
The study, published Monday in the journal Neurology, further suggests a link between cognitive decline and herpesviridae viral infections in particular, which previous studies have also linked to Alzheimer's disease and risk of stroke, an accompanying editorial notes. Herpesviridae is a family of viruses including HSV-1 or herpes simplex virus-1, which causes cold sores and can cause genital herpes, and HSV-2, which commonly causes genital herpes.

At least 40% of moms are feeding their infants solid foods far too early, according a new study published in the medical journal Pediatrics, and that may lead to problems for their children later in life.
Researchers wanted to know how many babies were being fed solid foods (including cereal and baby food) sooner than recommended, whether breast-feeding or formula feeding made a difference and why solids were being introduced early. When the study began in 2005, the American Academy of Pediatrics (AAP), which also publishes the journal Pediatrics, recommended introducing solid foods when babies were between 4 and 6 months old.
In 2012, the AAP changed those recommendations. Now it says babies shouldn't be eating solid food until they are about 6 months old.

Most packaged meals and snacks marketed to toddlers have more than the recommended amount of sodium per serving, meaning children as young as one are most likely eating far too much salt early in life, according to one of several studies on sodium presented this week.
The studies were presented at the American Heart Association's Epidemiology and Prevention/Nutrition, Physical Activity and Metabolism 2013 Scientific Sessions in New Orleans.
The findings were alarming to researchers since there is evidence a child's sodium intake is related to the likelihood that he or she will develop hypertension as an adult. Hypertension is a major risk factor of cardiovascular disease and the number-one killer of men and women in the United States. FULL POST

Being abused as a child may increase a mother's chance of having a child with autism, according to a new study, but researchers aren't sure why.
Investigators at The Harvard School of Public Health looked at more than 50,000 women in the Nurses' Health Study II group, and found that those who reported the highest levels of abuse as children themselves were 60% more likely to have children with some type of autism-spectrum disorder.

The number of children with autism is "significantly" higher than previously thought, according to a new report released by the Centers for Disease Control and Prevention.
School-aged boys were four times more likely to have an autism spectrum disorder (ASD) diagnosis than girls, according to the new data.
The CDC released a report a year ago estimating 1 in 88 American children has a form of autism spectrum disorder - neurodevelopmental disorders that lead to impaired language, communication and social skills. The report looked at medical and educational records of all 8-year-olds living in 14 areas of the United States during 2008. FULL POST

There are pouches on each side of the human nose below the eyes that are called maxillary sinuses. They're involved in sinus infections, so you may already have a bias against them.
But Nathan Holton, a postdoctoral research fellow in the department of orthodontics at the University of Iowa, wanted to find out why there's such variation in these structures, and how they are affected by variation in the nasal cavity. A study on the subject is published in the journal The Anatomical Record.
Holton and colleagues took computed tomography scans of 40 people. About half of them were European-Americans, and the other half were African-Americans or native South Africans. FULL POST

A new survey finds even though vaccines for certain teenage illnesses are available and are found to be safe, many parents aren't having their teens inoculated. The question is why?
Researchers looked at parent questionnaires collected through a national survey called "Reasons for Not Vaccinating Adolescents: National Survey of Teens, 2008-2010." Investigators wanted to better understand why moms and dads aren't taking their older children in for recommended inoculations.
“These vaccines are safe and effective and people should really have their teens get them," says Dr. Paul Darden, lead author of the study and professor of pediatrics at the University of Oklahoma College of Medicine. “Parents say pediatricians are telling them about the vaccines, yet they just don’t seem to understand why they are necessary or are skeptical about their safety."

A new study from Stanford University looks specifically at aspirin's role in reducing the risk of melanoma , a form of skin cancer that is on the rise.
The study found a significant association between frequent usage of the drug and this form of cancer; aspirin users were less likely to get melanoma than those who did not take aspirin.
This is not proof, however, that aspirin is directly responsible for lowering the risk.
