An alternative technique for performing minimally invasive release of carpal tunnel syndrome is described. The suggested methodology is based on transillumination of the carpal tunnel during surgery. The advantages of the technique are discussed and compared with other available surgical procedures including endoscopy. The authors also describe preliminary operative results in 50 consecutive pa...

Flow limitation during forced exhalation and gas trapping during high-frequency ventilation are affected by upstream viscous losses and by the relationship between transmural pressure (Ptm) and cross-sectional area (A(tr)) of the airways, i.e., tube law (TL). Our objective was to test the validity of a simple lumped-parameter model of expiratory flow limitation, including the measured TL, stati...

We present a three-dimensional (3D) image reconstruction scheme for optical near-infrared imaging of highly scattering material. The algorithm reconstructs the spatial distribution of the optical parameters of a volume Omega from transillumination measurements on the boundary of Omega. We test the performance of the method for a cylindrical object with embedded absorbing perturbation for a numb...

Resting heart rates in 18 species of spiders as determined by a cool laser transillumination technique range from 9 to 125 beats per minute. Cardiac frequencies obtained in this fashion may readily serve as a measure of standard rates of metabolism. A spider's resting heart rate is a function of body size and of foraging energetics.

OBJECTIVES We hypothesized that transillumination would increase peripheral intravenous (IV) insertion success rates in pediatric emergency department patients. Primary outcome was success in first attempt, and secondary outcome was success within 2 attempts. METHODS We evaluated IV insertion by pediatric emergency department physicians and nurses using the Veinlite (TransLite, Sugar Land, Te...
