Richmond - The ticks were so bad last summer that Dr. Fred Robinson, a retired cardiologist, could hardly go for a walk in his yard in Midlothian without coming in to find a tick somewhere on his body.

They were a nuisance, but he now suspects they also are to blame for an unusual allergic reaction he has developed to beef.

It sounds improbable, but allergy doctors say patients such as Robinson are cropping up more and more, and research is pinning down a plausible explanation for what may be happening.

Much of that research is being done at the University of Virginia, where studies are also trying to help patients whose only remedy so far is to give up beef or other red meats.

"About 11 years ago I had a little teeny tick the size of a pinhead behind my left knee," Robinson, said, explaining his ordeal.

"I got part of the tick out. But part of it didn't come out. For years, it would flare up," he said, referring to the area on his leg where the tick was attached.

Scarlet fever--past and present

While "flesh-eating infections" caused by the group A streptococcus (Streptococcus pyogenes) may grab more headlines today, one hundred and fifty years ago, the best known and most dreaded form of streptococcal infection was scarlet fever. Simply hearing the name of this disease, and knowing that it was present in the community, was enough to strike fear into the hearts of those living in Victorian-era United States and Europe. This disease, even when not deadly, caused large amounts of suffering to those infected. In the worst cases, all of a family's children were killed in a matter of a week or two. Indeed, up until early in the 20th century, scarlet fever was a common condition among children. The disease was so common that it was a central part of the popular children's tale, The Velveteen Rabbit, written by Margery Williams in 1922.

Luckily, scarlet fever is much more uncommon today in developed countries than it was when Williams' story was written, despite the fact that we still lack a vaccine for S. pyogenes. Is it gone for good, or is the current outbreak in Hong Kong and mainland China a harbinger of things to come?

Once broken, a compact fluorescent light bulb continuously releases mercury vapor into the air for weeks to months, and the total amount can exceed safe human exposure levels in a poorly ventilated room, according to study results reported in Environmental Engineering Science, a peer-reviewed online only journal published monthly by Mary Ann Liebert, Inc.

The amount of liquid mercury (Hg) that leaches from a broken compact fluorescent lamp (CFL) is lower than the level allowed by the U.S. Environmental Protection Agency (EPA), so CFLs are not considered hazardous waste. However, Yadong Li and Li Jin, Jackson State University (Jackson, MS) report that the total amount of Hg vapor released from a broken CFL over time can be higher than the amount considered safe for human exposure. They document their findings in the article "Environmental Release of Mercury from Broken Compact Fluorescent Lamps."

As people can readily inhale vapor-phase mercury, the authors suggest rapid removal of broken CFLs and adequate ventilation, as well as suitable packaging to minimize the risk of breakage of CFLs and to retain Hg vapor if they do break, thereby limiting human exposure.

One of nature's most perfect foods may be even better for us than previously thought.

While eggs are well known to be an excellent source of proteins, lipids, vitamins and minerals, researchers at the University of Alberta recently discovered they also contain antioxidant properties, which helps in the prevention of cardiovascular disease and cancer.

Jianping Wu, Andreas Schieber and graduate students Chamila Nimalaratne and Daise Lopes-Lutz of the U of A Department of Agricultural Food and Nutritional Science examined egg yolks produced by hens fed typical diets of either primarily wheat or corn. They found the yolks contained two amino acids, tryptophan and tyrosine, which have high antioxidant properties.

After analyzing the properties, the researchers determined that two egg yolks in their raw state have almost twice as many antioxidant properties as an apple and about the same as half a serving (25 grams) of cranberries.

Addis Ababa/Nairobi - Thousands of Ethiopians in Afar State are facing critical food, water and health gaps almost a month after a volcano erupted in neighbouring Eritrea's Nabro region, officials say.

The volcano started erupting on 12 June, spewing ash over hundreds of kilometres, affecting food and water sources as well as air travel in some parts. The eruption also caused an earthquake with a magnitude of 5.7, Eritrea's Information Ministry reported in a communiqué.

According to a report from Ethiopia's Afar Disaster Prevention and Food Security Programs Coordination Office: "The adverse impacts of the volcanic ash increased reports of livestock mortality, migration, critical water shortage, human health problems and rising malnutrition among the worst volcanic affected woredas [districts]: Bidu, Afdera, Erebti, Elidar, Teru and Kori.

FDA's New Sneak Attack on Supplements


Alliance for Natural Health
Tue, 05 Jul 2011 07:46 UTC

Just before the July 4 holiday weekend, hoping to limit media attention, the FDA dropped a bomb on dietary supplements. Don't let them get away with it! A new Action Alert.

On July 1, the US Food and Drug Administration issued draft guidance for complying with the New Dietary Ingredient (NDI) notification protocols contained in the Dietary Supplement Health and Education Act (DSHEA). Ever since DSHEA was enacted in 1994, supplement manufacturers have had very little guidance on what counts as an NDI and when or how to send an NDI notification. The government has arbitrarily ignored or enforced this section of DSHEA, doing as it liked, without spelling out the rules.

Why does this matter? Because when you hear New Dietary Ingredient (NDI), substitute "New Supplement" in your mind. What we are dealing with here is whether the supplement industry is allowed to innovate and create new supplements - and if so, under what rules.

5 surprising, life-changing facts to know about inflammation

Get ready for the health buzzword of 2011: inflammation. A key biochemical process inside every one of us, inflammation is the cornerstone of health and healing - and yet - unless you learn the secrets to managing it - it will also probably eventually kill you.

The good news: As scientists slowly but surely uncover how the inflammatory response works, they're learning how we can influence it to our benefit.

Here, five surprising - and life-changing - facts.

Comment: It's good to see awareness of inflammation hitting the mainstream, but this article is way off for recommending vegetables which are known inflammatory factors and a reduction in saturated fat from already dangerously low levels. SOTT sez: a HIGH-fat, ANIMAL-based Paleo diet will be a win-win for your body.

US: Home birth on the rise by a dramatic 20 percent

One mother chose home birth because it was cheaper than going to a hospital. Another gave birth at home because she has multiple sclerosis and feared unnecessary medical intervention. And some choose home births after cesarean sections with their first babies.

Whatever their motivation, all are among a striking trend: Home births increased 20 percent from 2004 to 2008, accounting for 28,357 of 4.2 million U.S. births, according to a study from the Centers for Disease Control and Prevention released in May.

White women led the drive, with 1 in 98 having babies at home in 2008, compared to 1 in 357 black women and 1 in 500 Hispanic women.

Sherry Hopkins, a Las Vegas midwife, said the women whose home births she's attended include a pediatrician, an emergency room doctor and nurses. "We're definitely seeing well-educated and well-informed people who want to give birth at home," she said.

Robbie Davis-Floyd, a medical anthropologist at the University of Texas at Austin and researcher on global trends in childbirth, obstetrics and midwifery, said "at first, in the 1970s, it was largely a hippie, countercultural thing to give birth outside of the hospital. Over the years, as the formerly 'lay' midwives have become far more sophisticated, so has their clientele."

Long term exposure to air pollution could damage the brain and lead to learning and memory problems and even depression, new research has revealed.

The tests on mice showed that in the long term dirty air could cause actual physical changes to the brain which in turn had negative effects.

While other studies have looked at the impact polluted air has on the heart and lungs this is one of the first to look at the effect on the brain, lead author Laura Fonken noted. She said:
"The results suggest prolonged exposure to polluted air can have visible, negative effects on the brain, which can lead to a variety of health problems.

"This could have important and troubling implications for people who live and work in polluted urban areas around the world."
Ms Fonken, a doctoral student, and her colleagues at Ohio State University exposed mice to either filtered air of polluted air six hours a day, five days a week for almost half their lifespan which was 10 months.

Perfluorochemicals Linked With Impulsivity in Children

Industrial Pollutants: Scientists find that high blood levels correlate with a core feature of attention deficit hyperactivity disorder.

Children's exposure to a growing list of industrial chemicals, including certain pesticides and phthalates, has been linked to development of attention deficit hyperactivity disorder (ADHD). Now evidence suggests that perfluorinated chemicals (PFCs) boost ADHD risks by making children prone to impulsive behavior (Environ. Sci. Technol., DOI: 10.1021/es103712g).

Used since the 1950s to make Teflon and many other stain- and water-repellent products, PFCs are now global contaminants. Scientists had already associated elevated PFCs with neurological problems, such as delayed gross motor development. A study published in December found tantalizing links between blood PFC levels and diagnoses of ADHD (Environ. Health Perspect., DOI: 10.1289/ehp.1001898). Brooks Gump, a psychologist at Syracuse University, wanted to go one step further: He and his colleagues were interested in how the chemicals might affect impulsivity, a core ADHD feature. Impulsivity has cascading effects on so-called "executive functions," such as planning, verbal regulation, and motor control. ADHD is a complex and multi-faceted diagnosis, Gump notes, that results from deficits in executive functioning. By identifying any influence that PFCs have on impulsivity, Gump hoped to connect the dots between chemical exposure, nervous system effects, and processes leading to ADHD.
