Normality Ranges of Menstrual Fluid Volume During Reproductive Life Using Direct Quantification of Menses with Vaginal Cups.

Objective: To determine the normal limits of menstrual fluid volume during reproductive life, quantified by direct measurement.

Methods: This was an observational, prospective clinical trial of healthy women aged 20-49 years old, with normal menstrual periods, recruited in a Natural Family Planning Unit. Women collected their menstrual fluid for at least 3 menstrual periods using a vaginal cup.

Dental students' evaluations of an interactive histology software.

This study assessed dental students' evaluations of a new Interactive Histology Software (IHS) developed by the authors and compared students' assessment of the extent to which this new software, as well as other histology teaching methods, supported their learning. The IHS is a computer-based tool for histology learning that presents high-resolution images of histology basics as well as specific oral histologies at different magnifications and with text labels. Survey data were collected from 204 first-year dental students at the Universidad Austral de Chile.

Laparoscopic repair of vaginal vault prolapse.

Purpose Of Review: Currently, the two laparoscopic techniques available and described in the literature for the treatment of vaginal vault prolapse are uterosacral ligament vault suspension and sacrocolpopexy. These two techniques are opposing each other fundamentally. While the first is reconstructive, the second is essentially palliative.

Chilean miners commuting from sea level to 4500 m: a prospective study.

The development of mining activities in North Chile involves a great number of workers intermittently exposed to high altitude for a long period of time (chronic intermittent hypoxia, CIH). A 2(1/2)-year prospective study aimed to characterize this model of exposure to CIH and to know whether this condition may progressively lead to a chronic pattern. Twenty-nine miners, aged 25 +/- 5 yr, working 7 days at HA (3800 to 4600 m) and resting 7 days at sea level (SL) were studied.
