Dengue fever may be more than three times more prevalent than current estimates, according to a new report.
The study, led by researchers at the University of Oxford in England, estimates there are 390 million dengue infections around the world each year. Currently, the World Health Organization puts the number between 50 and 100 million infections each year. Researchers hope their findings will help pinpoint parts of the world most vulnerable to dengue fever and develop strategies to treat it.

Exposure to intimate partner violence and maternal depression before the age of 3 may increase a child's risk of developing attention deficit hyperactivity disorder (ADHD), according to a new study published in the journal JAMA Pediatrics.
Researchers at the Indiana University School of Medicine looked a population of more than 2,000 children, and found that those whose parents had reported depression or intimate partner violence were significantly more likely to suffer from ADHD as they grew older.
"It wasn't surprising, from the lens of me being a behavioral pediatrician," said Dr. Nerissa Bauer, an assistant professor of pediatrics at the IU School of Medicine and the lead study author. "I routinely encounter mental health and behavioral problems in children, and this supports my initial hunch that I was seeing an increase in that." FULL POST

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

Children raised by gay or lesbian couples benefit when their parents are allowed to marry, America’s top pediatrics group said Thursday in support of same-sex marriage.
“If a child has two living and capable parents who choose to create a permanent bond by way of civil marriage, it is in the best interest of their child(ren) that legal and social institutions allow and support them to do so, irrespective of their sexual orientation,” the American Academy of Pediatrics said in a policy statement.
Dr. Ellen Perrin, co-author of the policy statement, says marriage gives children of same-sex couples the same advantages of any married couple’s children. 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
