Evaluation of the analytical performance of a fuel cell breath alcohol testing instrument: a seven-year comprehensive study.

Between 2003 and 2009, 54,255 breath test sequences were performed on 129 AlcoSensor IV-XL evidential instruments in Orange County, CA. The overall mean breath alcohol concentration and standard deviation from these tests was 0.141 ± 0.

Relationship of creative projects in anatomy to medical student professionalism, test performance and stress: an exploratory study.

Background: The anatomy course offers important opportunities to develop professionalism at an early stage in medical education. It is an academically significant course that also engenders stress in some students.

Methods: Over a three-year period, 115 of 297 students completed creative projects.

Discernment of adipose versus nervous tissue: a novel adjunct solution in lipomyelomeningocele surgery.

Objective: To determine a solution capable of discerning adipose versus nervous tissue, to aid in surgical separation of the adipose tissue which appears to be visually indistinguishable from nervous tissue in lipomyelomeningoceles (LMMs).

Methods: The following solutes (in normal saline) were investigated, both at 25 and 37 degrees C: beta-carotene, vitamin D, vitamin E, lecithin, hydrogen peroxide, lipase, protease, hyaluronidase, partially purified collagenase, purified collagenase, trypsin, trypsin plus purified collagenase and non-solute-containing saline (control). Each solution was applied to a pediatric lipoma to determine gross effects over a period of approximately 30 min.
