Pregnancy Hormone May Reduce Multiple Sclerosis Symptoms : Shots – Health News : NPR

For decades, women with multiple sclerosis have noticed that they tend to do better while they are pregnant. That has led to an experimental drug for the disease that’s based on a hormone associated with pregnancy.The hormone is a form of estrogen called estriol. It’s abundant in a woman’s body only when she is pregnant. Adding estriol to treatment with an existing MS drug cut relapses by 47 percent in a of 158 women presented at the American Academy of Neurology meeting in April.

Calling Young Girls ‘Fat’ May Increase Their Teen-Obesity Risk

HealthDay News — When people tell a young girl that she’s fat, that in itself increases her risk of eventually becoming obese, according to a new study.The study included more than 2,300 young girls in California, Cincinnati and Washington, D.C., who had their height and weight checked when they age 10 and again at age 19.At the start of the study, 58 percent of the girls had been told by a parent, sibling, friend, classmate or teacher that they were too fat. Those girls were 1.66 times more likely to be obese at age 19 than other girls, the University of California, Los Angeles UCLA researchers found.

New Clues to Link Between MS Drug Tysabri and Rare Brain Disease

HealthDay News — Researchers report that they think they have figured out why patients who take the multiple sclerosis drug Tysabri face a high risk of developing a rare, and sometimes fatal, brain infection.A common virus that can cause the brain disease progressive multifocal leukoencephalopathy PML likes to infect and hide in certain blood cells that are triggered to mobilize by Tysabri, the study authors explained. Even more troubling, the researchers discovered that current tests may be missing some who harbor the virus.

Low Iron in Brain a Sign of ADHD?

MONDAY, Dec. 2, 2013 (HealthDay News) — A newer MRI method can detect low iron levels in the brains of children with attention-deficit/hyperactivity disorder (ADHD).

The method could help doctors and parents make better informed decisions about medication, a new study says.

Psychostimulant drugs used to treat ADHD affect levels of the brain chemical dopamine. Because iron is required to process dopamine, using MRI to assess iron levels in the brain may provide a noninvasive, indirect measure of the chemical, explained study author Vitria Adisetiyo, a postdoctoral research fellow at the Medical University of South Carolina.

If these findings are confirmed in larger studies, this technique might help improve ADHD diagnosis and treatment, according to Adisetiyo.

Childhood Depression and Sleep Apnea

We have noted a significant correlation between depression and sleep disorders in adults for years. However, in this month’s issue of Journal of Clinical Sleep Medicine, a study entitled The Relationship between Depressive Symptoms and Obstructive Sleep Apnea in Pediatric Populations: A Meta-Analysis, demonstrated the increased incidence of depression in children from preschool up to age 18 with sleep apnea.It is well-known that childhood depression is a significant problem. Depression affects 1% of preschoolers, 2% of school-age children, and up to 8% of adolescents. If untreated, it poses a significant risk for increased psychosocial problems, as well as substance abuse and suicide. It is also known that about 2% of all children in this age group suffer from sleep-disordered breathing.

Laser Toys Can Damage Eyes: Report

(HealthDay News) — Popular laser toys can cause serious and potentially permanent eye damage, a new report warns.

The high-powered blue laser gadgets, sold over the Internet, are increasingly sought after by male teens and young adults, according to the researchers.

The study authors report on 14 cases of laser-caused eye damage treated at Saudi Arabia’s King Khaled Eye Specialist Hospital between 2012 and 2013. The injuries were caused by high-power blue laser gadgets and included four cases of perforations of the retina, the part of the eye responsible for detailed central vision.

Think You Know What Your Child’s Up to Online? Think Again

(HealthDay News) — Parental perceptions can be way off when it comes to what their kids are exposed to while surfing the Internet, according to a new study that puts an e-spin on the enduring generation gap.

The survey of 456 parent-child pairs revealed that although nearly one-third of the 10- to 16-year-olds polled said they had been bullied online, just 10 percent of parents were aware of that.

Parents also underestimated how often their child was exposed to online pornography, the survey found.

Such parent-child disconnects highlight the need for greater parental involvement in their child’s cyber world, the researchers said.
