Study reveals major shift in how eczema develops
Not 1, but 2 skin barriers influential in most common skin disease
Like a fence or barricade intended to stop unwanted intruders, the skin serves as a barrier protecting the body from the hundreds of allergens, irritants, pollutants and microbes people come in contact with every day. In patients with eczema, or atopic dermatitis, the most common inflammatory human skin disease, the skin barrier is leaky, allowing intruders – pollen, mold, pet dander, dust mites and others – to be sensed by the skin and subsequently wreak havoc on the immune system.
While the upper-most layer of the skin – the stratum corneum – has been pinned as the culprit in previous research, a new study published today in the Journal of Allergy and Clinical Immunology *** found that a second skin barrier structure, consisting of cell-to-cell connections known as tight junctions, is also faulty in eczema patients and likely plays a role in the development of the disease. Tightening both leaky barriers may be an effective treatment strategy for eczema patients, who often have limited options to temper the disease.
“Over the past five years, disruption of the skin barrier has become a central hypothesis to explain the development of eczema,” said Lisa Beck, M.D., lead study author and associate professor in the Department of Dermatology at the University of Rochester Medical Center. “Our findings challenge the belief that the top layer of the skin or stratum corneum is the sole barrier structure: It suggests that both the stratum corneum and tight junctions need to be defective to jumpstart the disease.”
Currently, there are no treatments that target skin barrier dysfunction in eczema. To treat eczema, which causes dry, red, itchy skin, physicians typically prescribe anti-inflammatory drugs, like prednisone, and a variety of topical anti-inflammatory creams and ointments. But, modest benefit, negative side effects and cost concerns associated with these therapies leave patients and doctors eagerly awaiting new alternatives.

Research suggests exposure to electromagnetic fields before and after birth might play role
MONDAY, Dec. 6 (HealthDay News) — Children exposed to cell phones in the womb and after birth had a higher risk of behavior problems by their seventh birthday, possibly related to the electromagnetic fields emitted by the devices, a new study of nearly 29,000 children suggests.
The findings replicate those of a 2008 study of 13,000 children conducted by the same U.S. researchers. And while the earlier study did not factor in some potentially important variables that could have affected its results, this new one included them, said lead author Leeka Kheifets, an epidemiologist at the School of Public Health at the University of California at Los Angeles.
“These new results back the previous research and reduce the likelihood that this could be a chance finding,” said Kheifets. She stressed that the findings suggest, but do not prove, a connection between cell phone exposure and later behavior problems in kids.
The study was published online Dec. 6 in the Journal of Epidemiology and Community Health.

“Animated Anatomies explores the visually stunning and technically complex genre of printed texts and illustrations known as anatomical flap books. These publications invite the viewer to participate in virtual autopsies, through the process of unfolding their movable leaves, simulating the act of human dissection. This exhibit traces the flap book genre beginning with early examples from the sixteenth century, to the colorful “golden age” of complex flaps of the nineteenth century, and finally to the common children’s pop-up anatomy books of today.”

If these do not fit your needs, consider going to a nearby public, academic, or medical library.
Many academic and medical libraries are open to the public (all libraries receiving state funding are open to the public). Don’t forget to ask for a reference librarian if you would like professional assistance!
Many academic and medical libraries provide at least some reference assistance to the public. Call ahead and ask about library services to the public. You may be pleasantly surprised.
