Swaddling: a traditional care method rediscovered.

Background: This study was undertaken to compare the sleep profiles of healthy infants in swaddling and sleeping bag conditions.

Methods: Polysomnographs of 85 healthy infants (40 in the study group, 45 in the control group) with a mean age of 7.5 weeks were recorded in the sleeping laboratory.

In vivo confocal scanning laser microscopy: comparison of the reflectance and fluorescence mode by imaging human skin.

Optical, noninvasive methods have become efficient in vivo tools in dermatological diagnosis and research. From these promising imaging techniques, only the confocal scanning laser microscopy (CSLM) provides visualization of subsurface skin structures with resolutions similar to those of light microscopy. Skin annexes, as well as cutaneous cells from different epidermal layers, can be distinguished excellently.
