Pulsed dye laser and non-ablative wrinkle reduction.

BACKGROUND AND OBJECTIVES: Non-ablative wrinkle reduction is currently an issue, which is being widely discussed in the literature and at academic meetings worldwide. We present the findings of our randomized within patient controlled clinical trial into periorbital wrinkle reduction with a 595 nm pulsed dye laser. STUDY DESIGN/MATERIALS AND METHODS: Twenty-six volunteers, 25 female and 1 male were enrolled into our study. The study was set up as a randomized within patient controlled clinical trial. Subjects received one treatment to the periorbital wrinkles around one eye, using the other as the control. They were then observed at 3 and 6 months post treatment. They then received three treatments spaced 4 weeks apart and were again observed at 3 and 6 months. The author and one blinded assessor reviewed them independently. At the end of the trial a panel of three blinded assessors scored photographs of the subjects independently. The Fitzpatrick wrinkle score was used to score the subjects. All data was subjected to statistical analysis using non-parametric t-tests. RESULTS: Statistical analysis revealed no significant differences in the wrinkle scores of the patients upon completion of the trial protocols. CONCLUSIONS: The 595 nm pulsed dye laser set at 0.5 millisecond pulse width is not an effective means of achieving sub-purpuric non-ablative periorbital wrinkle reduction.

Preventable feto-infant mortality: application of a conceptual framework for perinatal health surveillance to Manitoba perinatal outcomes.

BACKGROUND: Perinatal health surveillance systems have lacked conceptual frameworks to translate data into information for policy and program planning. This paper demonstrates the application of a conceptual framework in the analysis of feto-infant mortality data in the province of Manitoba. METHODS: Fetal and infant deaths were categorized according to a two-dimensional framework of birthweight and age-at-death, and grouped into four broad categories of contributors to perinatal health: Maternal Health, Maternal Care, Newborn Care, and Infant Care. Birth Weight Proportionate Mortality Rates (BWPMR) were calculated for each of the four categories, and preventable "excess" feto-infant mortality was estimated through comparisons to a benchmark sub-population. RESULTS: Between 1985 and 1998, feto-infant mortality declined from 12.3 to 9.8 deaths per 1000 births in Manitoba. Much of this decline occurred in the Newborn Care category; there were only slight declines in deaths attributed to Maternal Health and Infant Care factors. Comparison of the feto-infant mortality rate to the benchmark rate revealed an excess of 3.46 deaths per 1000 births, an "opportunity gap" of 33%. Substantial regional variations in feto-infant mortality rates were observed. SUMMARY: Application of this conceptual framework provided useful information to aid in policy and program planning. As the greatest excess feto-infant mortality was observed in the Maternal Health and Infant Care categories, attention to the broader determinants of health which influence these categories will be required.
