Nanoparticle technology fights peanut allergy

Nanoparticle technology fights peanut allergy

The much-anticipated arrival of a vaccine for severe peanut allergy is still unfulfilled. There seem to be too many unresolved issues with the vaccines currently being tested — whether they be injectable or oral vaccines. Safety concerns and avoidance of unwanted reactions are instrumental in this delay. Enter nanoparticle technology. Perhaps because the amount of peanut protein used in nanoparticle vaccines is so small, there have been no severe reactions to the vaccine. Also, early studies show that the nano-vaccine…

Hard water known to cause infant eczema

Hard water known to cause infant eczema

Although it’s been suspected that hard water contributes to the development of eczema in infants, the premise had never been scientifically researched until investigators at St. George’s University in Canada have now proven it is so. Hard water (water with high calcium content) and water with higher chlorine content were both found to increase the likelihood of eczema in infants by 46%. The investigators also found the installation of a water softener removed this increased risk.

Tiniest cells causing big misery in young and old

An infection that previously was mostly seen in children, over the past 15 years has been showing up more frequently in older adults. With its extended incubation period (2-4 weeks), it is difficult to diagnose, and capable of emerging as bronchitis or pneumonia. And it is caused by the smallest free-living organisms — Mycoplasma pneumoniae — that were originally thought to be viruses, but have been shown to be bacteria. Unlike most bacteria they lack a cell wall and are…

New shingles vaccine? Not quite yet

New shingles vaccine? Not quite yet

The lead article in the New England Journal of Medicine last month was on a new shingles vaccine. The study involved 15,000 people over age 70 in 18 different countries. Unlike the currently used shingles vaccine which uses a live virus, the new vaccine uses a single protein from the virus, along with an immune stimulator. The new vaccine, which is called HZ/su (Herpes Zoster subunit) prevented shingles in 92% of the patients, and prevented the dreaded complication of shingles…

Q – Tips: Asthma and fracking

Q – Tips: Asthma and fracking

John Hopkins Epidemiologists have found that asthmatics who live in areas of the country where fracking is done have an increased incidence of hospital/ER-requiring flare-ups — that is four times greater than their counterparts not exposed to the environmental leak of natural gas.

Allergic clock might tick in our favor

Allergic clock might tick in our favor

Research scientists in Tokyo have been working on resetting the allergic clock in mice to lessen their tendency to allergy. Our daily circadian clock, which is critical for many of our biological systems, is located in a special area in the hypothalamus of our brain called the light-sensitive central oscillator. It is programmed by the varying exposure to light and dark. In turn, it signals all the peripheral oscillators (clocks) found in individual cells throughout the body. This includes the…

Caring for childhood eczema clearer

Caring for childhood eczema clearer

Just-published research of eczema in children – and the accompanying sleep interruption it causes the kids and their parents – has led to a recommended treatment. University of Nevada researchers compared the benefit of antihistamines versus topical steroids to control the itch/scratching in children with eczema. They found that both forms of therapy were effective. In fact, they were equally good in preventing sleep disturbance from nocturnal itch – a particularly vexing symptom for families because it causes significant loss…
