TORONTO - Tina Szenasi's quest to cure her two autistic sons began with soy milk.
Ms. Szenasi switched to the milk substitute after reading testimonials from other parents who said their autistic children's symptoms had improved - even disappeared - when dairy and wheat were eliminated from their diet.
People with coeliac disease are waiting an average of 13 years to be diagnosed, a poll has revealed.
The gut disorder is caused by gluten intolerance, and can lead to bone problems, infertility or bowel cancer.
The charity Coeliac UK says some of the 800 patients surveyed reported seeing their GP almost 30 times before being diagnosed.
But it says the condition can be easily detected by GPs using a quick and simple blood test.
People with coeliac disease can experience a range of symptoms, including as bloating, diarrhoea, chronic fatigue, breathlessness, depression and weight gain.
WASHINGTON -- A parasitic disease rarely seen in United States but common in the Middle East has infected an estimated 2,500 US troops in the last four years because of massive deployments to remote combat zones in Iraq and Afghanistan, military officials said.
Alcohol consumption more severely affects women than men, according to a new study by researchers at RTI International, Pavlov Medical University, Leningrad Regional Center of Addictions, Pacific Institute for Research and Evaluation and Johns Hopkins School of Medicine.
The study, published in the May issue of Alcoholism: Clinical and Experimental Research, found that women become alcohol dependent more quickly than men and that alcohol more severely impairs women's cognitive functioning including perceptual and visual planning and processing, working memory and motor control.
"Our studied showed that female alcoholics experience a greater decrement in cognitive and motor functions and sustain an accelerated decline in processing speed than males," said Barbara Flannery, Ph.D., research psychologist at RTI. "Our findings confirm and extend prior research that alcohol exerts more profound adverse effect more quickly on women compared to men."
According to a new brain study, even people who seemed resilient but were close to the World Trade Center when the twin towers toppled on Sept. 11, 2001, have brains that are more reactive to emotional stimuli than those who were more than 200 miles away.
That is the finding of a new Cornell study that excluded people who did not have such mental disorders as post-traumatic stress disorder (PTSD) or major depression. One of the first studies to look at the effects of trauma on the brains of healthy people, it is published in the May issue of the journal Emotion.
The growing premature birth rate in the United States appears to be strongly associated with increased use of pesticides and nitrates, according to work conducted by Paul Winchester, M.D., professor of clinical pediatrics at the Indiana University School of Medicine. He reports his findings May 7 at the Pediatric Academic Societies' annual meeting, a combined gathering of the American Pediatric Society, the Society for Pediatric Research, the Ambulatory Pediatric Association and the American Academy of Pediatrics.
Dr. Winchester and colleagues found that preterm birth rates peaked when pesticides and nitrates measurements in surface water were highest (April-July) and were lowest when nitrates and pesticides were lowest (Aug.-Sept.).
More than 27 million U.S. live births were studied from 1996-2002. Preterm birth varied from a high of 12.03% in June to a low of 10.44% in September. The highest rate of prematurity occurred in May-June (11.91%) and the lowest for Aug-Sept (10.79%) regardless of maternal age, race, education, marital status, alcohol or cigarette use, or whether the mother was an urban, suburban or rural resident. Pesticide and nitrate levels in surface water were also highest in May-June and lowest in August - September, according to the U.S. Geological Survey.

Regulators in the U.S. are warning drugmakers, suppliers and health professionals to be on the alert for counterfeit medicine additives that substitute a poison used in antifreeze for a common sweetener.
In order to comprehend the continuous stream of cacophonies and visual stimulation that battle for our attention, humans will breakdown activities into smaller, more digestible chunks, a phenomenon that psychologists describe as "event structure perception."
Event structure perception was originally believed to be confined to our visual system, but new research shows that a similar process occurs when reading about everyday events as well.
Nicole Speer and her colleagues at Washington University examined event structure perception by having subjects read narratives about everyday activities while undergoing functional Magnetic Resonance Imaging (fMRI) to measure neural activity. The subjects were then invited back a few days later to reread these same narratives, this time without the fMRI scan. Instead, they were asked to divide the narrative where they believed one segment of narrative activity ended and another segment began.
Unintentional weight loss in older adults often leads to frailty, a decline in physical function and even death. So is it wise for older, overweight women to embark on a weight loss program? New research from Wake Forest University Baptist Medical Center suggests that these women are better off trying to lose weight - even if they regain some of it.
"Our results suggest that losing weight through calorie cutting won't lead to increased disability in older women," said Jamehl Demons, M.D., lead investigator on a project evaluating the effects of weight loss on physical performance.
And even when some of the weight was regained, the women still came out ahead.
"It looks like they are better off than if they had never tried to lose weight," said Mary F. Lyles, M.D., lead investigator on an analysis exploring how dieting affected body composition.
The results of both projects - which are part of the larger Diet, Exercise and Metabolism in Older Women (DEMO) study - are being presented today (May 4) at the annual meeting of the American Geriatrics Society in Seattle.
Multitasking seems to come easier for some and is virtually impossible for others, however new research shows that it is difficult for all in the late night and early morning.
Previous studies have shown that the time of day greatly affects human's reaction time (for a review, see Carrier & Monk, 2000). This performance decrement is constantly found during the night with its' lowest point in the early morning. This leads to the assumption that the time of day directly affects the speed of cognitive processing.
Daniel Bratzke at the University of Tuebingen wished to take these studies a bit further and figure out what makes our reaction time so slow during the wee hours. While many researchers have studied this, Bratzke focused on one of the three stages of human processing because he argues that measuring overall reaction time does not allow researchers to separate the effects of three different processing stages. Bratzke describes, for example, that the stage models of human performance assume at least three distinct processing stages: early perceptual, central decisional and late motor. He writes, "Given this widely accepted view, the question arises whether time of day affects all processing stages in general or one or more stages selectively."
