Metronidazole for Prevention of Pelvic Cellulitis and Abscess after Laparoscopic Hysterectomy: A Triple-blinded, Randomized, Placebo-controlled Clinical Trial.

Study Objective: To determine whether a postoperative 5-day treatment schedule with vaginal metronidazole added to conventional antibiotic prophylaxis with 2 g cefazolin modifies the risk of pelvic cellulitis (PC) and pelvic abscess (PA) after total laparoscopic hysterectomy (TLH).

Design: A randomized, controlled, triple-blind, multicenter clinical trial.

Setting: Two centers dedicated to minimally invasive gynecologic surgery in Colombia.

Effects of an oral health education program for pregnant women.

Purpose: The purpose of this study was to evaluate the gain in knowledge of oral health after education to pregnant women on dental anticipatory guidance and to determine how much of this information pregnant women retain over time.

Methods: The study consisted of 40 pregnant women. Inclusion criteria included: (1) between the ages of 21-40; (2) in 12-40th week of pregnancy; and (3) spoke English.

Comparison of naïve and expert subjects in the assessment of small color differences.

Determination of the role of subject experience in the development of accurate color difference formulas is of potentially critical concern. As part of a larger multivariable experiment investigating the minimum inter- and intra-subject variability possible among a set of subjects, a study was conducted to compare the performance of 25 novice versus 25 expert visual assessors for a set of 27 pairs of colored textile samples using a controlled psychophysical method and several statistical techniques including t-test, ANOVA, and Standardized Residual Sum of Squares (STRESS) functions. Experts exhibited approximately 43% higher visual difference ratings than novice subjects when assessing sample pairs having small color differences.

The quality of dental faculty work-life: report on the 2007 dental school faculty work environment survey.

This report is the third in a series of articles on the dental school work environment commissioned by the American Dental Education Association's Commission on Change and Innovation in Dental Education. The report is based on the most extensive research to date on faculty satisfaction in the dental school environment. The purpose of the study was to assess faculty perceptions and recommendations related to work environment, sources of job satisfaction and dissatisfaction, and professional development needs.

Unique-hue stimulus selection using Munsell color chips.

Presented are intra- and inter-observer variability data comparing the unique-hue (UH) selections of sets of males and females, using two different visual experimental procedures incorporating Munsell color chips of varying hue but identical chroma and value. Although 34 of the 40 Munsell hue chips were selected by at least one observer as a UH, selections were generally repeatable. In addition, intra-observer variability represented approximately 15% of inter-observer variability.
