The prognostic role of various indices and ratios of Doppler velocimetry in patients with pre-eclampsia.

Doppler velocimetry is a non-invasive method to monitor pregnancies complicated by pre-eclampsia. We aimed to assess the predictive value of adverse perinatal or maternal outcome of three ratios, i.e. middle cerebral to umbilical arteries pulsatility indices (PI), middle cerebral to uterine arteries PI and uterine to umbilical arteries PI, compared with that of uterine and umbilical arteries PI in pre-eclamptic patients. This is a cohort study on 168 singleton pregnancies between January 2010 and June 2013. Doppler velocimetry was performed at the diagnosis of pre-eclampsia. Logistic regression analysis was performed and receiver-operating characteristics (ROC) curves were calculated to determine the predictive ability of each Doppler index. Multivariate analysis was run to adjust results for confounding parameters. Seventy-eight cases were complicated by adverse perinatal outcome, 79 by maternal one, 49 by both. Considering perinatal outcome, area under ROC curve was 0.730 for uterine arteries PI, 0.691 for umbilical artery PI and 0.834 for middle cerebral to uterine arteries PI ratio, while for maternal one 0.720 for uterine arteries PI, 0.686 for umbilical artery PI and 0.817 for middle cerebral to uterine arteries PI ratio. At multivariate analysis, only middle cerebral to uterine arteries PI ratio remain statistically significant for both outcomes (p = 0.001). The cited ratio appeared more accurate than all other considered indices in predicting perinatal and maternal outcomes in patients affected by pre-eclampsia.

Hemorrhoidal laser procedure: short- and long-term results from a prospective study.

BACKGROUND: We report the results of 2-year regular use of the hemorrhoidal laser procedure (HeLP) in 97 patients with symptomatic second- to third-grade hemorrhoids with minimal or moderate internal mucosal prolapse. METHODS: Data on duration of the procedure, perioperative complications, postoperative pain, downgrading of hemorrhoids, resolution or persistency, and recurrence of hemorrhoidal disease (HD) were prospectively collected. RESULTS: No significant intraoperative complications occurred. The median follow-up was 15 months. Postoperative pain was null in most patients. There were no cases of rectal tenesmus or alteration of defecation habits. Symptoms and HD downgrading reached a "plateau" at 3 to 6 months after the HeLP. At this evaluation, frequency of bleeding, pain, itching, and hemorrhoidal acute syndrome decreased by 76% to 79%. HD grade showed a significant reduction. HD recurrence rate was 5% at 2 years. CONCLUSIONS: Our study demonstrates that the HeLP is a safe, effective, and painless technique for the treatment of symptomatic second- to third-grade hemorrhoids with minimal or moderate mucosal prolapse, ideally suitable as ambulatory treatment.
