Human papillomavirus infections in Mexican women with normal cytology, precancerous lesions, and cervical cancer: type-specific prevalence and HPV coinfections.

The prevalence and genotype distribution of human papillomavirus (HPV) provides the basis for designing HPV prevention programs. The prevalence rates of type-specific HPV and coinfections in samples of Mexican women were investigated in 822 women aged 18-87 years. HPV detection was performed using a Linear Array™ genotyping test.

[Increase S/D ratio in uterine artery as a predictor for preeclampsia in adolescent patients].

Background: Pregnancy during adolescence has been rising in the past years, and it is well known that preeclampsia affects teenagers, because maternal age and primigravida are risk factors. There are different ways and methods to predict preeclampsia, for example doppler velocimetry.

Objective: Determine S/D ratio of uterine artery in pregnant teenagers between 24-28 weeks and correlation with preeclampsia.
