Large families and animals keep allergies at bay

Cohort study of sibling effect, infectious diseases, and risk of atopic dermatitis during first 18 months of life BMJ Online First



Having siblings, keeping a pet, or living on a farm helps protect infants against the development of atopic (allergic) diseases, but early infections increase the risk, according to new research from Denmark. This study will be available on bmj.com on Friday 30 May 2004.

Researchers conducted four separate interviews with over 24,000 pregnant women (twice during their pregnancy and again when their child was 6 and 18 months old).


Information on atopic dermatitis and infections before 6 months of age were recorded. Data on factors associated with exposure to microbes, such as number of siblings, pet keeping, living on a farm, and attending day care, were also collected.

The risk of atopic dermatitis increased with each infectious disease before 6 months of age. This contrasts with the common belief that infectious diseases early in life may protect against the development of allergic diseases.

However, the risk of atopic dermatitis decreased with each additional exposure to three or more siblings, day care, pet ownership, and farm residence. This protective effect remained after adjusting for number of infectious diseases, suggesting that it is established independently and very early in life, say the authors.

These findings support the importance of microbial exposure for preventing atopic dermatitis, but challenge the hypothesis that infectious diseases in infancy protect against its development, they conclude.

Im Focus: Scientists channel graphene to understand filtration and ion transport into cells

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.

To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...

Im Focus: Towards data storage at the single molecule level

The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.

Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...

Im Focus: A space-time sensor for light-matter interactions

Physicists in the Laboratory for Attosecond Physics (run jointly by LMU Munich and the Max Planck Institute for Quantum Optics) have developed an attosecond electron microscope that allows them to visualize the dispersion of light in time and space, and observe the motions of electrons in atoms.

The most basic of all physical interactions in nature is that between light and matter. This interaction takes place in attosecond times (i.e. billionths of a...
