Urogenital infections afflict an estimated one billion people each year. The size of this problem and the increased prevalence of multi-drug resistant pathogens make it imperative that alternative remedies be found. A randomized, placebo-controlled trial of 64 healthy women given daily oral capsules of Lactobacillus rhamnosus GR-1 and Lactobacillus fermentum RC-14 for 60 days showed no adverse effects. Microscopy analysis showed restoration from asymptomatic bacterial vaginosis microflora to a normal lactobacilli colonized microflora in 37% women during lactobacilli treatment compared to 13% on placebo (P=0.02). Lactobacilli were detected in more women in the lactobacilli-treated group than in the placebo group at 28 day (P=0.08) and 60 day (P=0.05) test points. Culture findings confirmed a significant increase in vaginal lactobacilli at day 28 and 60, a significant depletion in yeast at day 28 and a significant reduction in coliforms at day 28, 60 and 90 for lactobacilli-treated subjects versus controls. The combination of probiotic L. rhamnosus GR-1 and L. fermentum RC-14 is not only safe for daily use in healthy women, but it can reduce colonization of the vagina by potential pathogenic bacteria and yeast.

Puberty is an important developmental stage wherein hormonal shifts mediate the physical and physiological changes that lead to menarche, but until now, the bacterial composition of vaginal microbiota during this period has been poorly characterized. We performed a prospective longitudinal study of perimenarcheal girls to gain insight into the timing and sequence of changes that occur in the vaginal and vulvar microbiota during puberty. The study enrolled 31 healthy, premenarcheal girls between the ages of 10 and 12 years and collected vaginal and vulvar swabs quarterly for up to 3 years. Bacterial composition was characterized by Roche 454 pyrosequencing and classification of regions V1 to V3 of 16S rRNA genes. Contrary to expectations, lactic acid bacteria, primarily Lactobacillus spp., were dominant in the microbiota of most girls well before the onset of menarche in the early to middle stages of puberty. Gardnerella vaginalis was detected at appreciable levels in approximately one-third of subjects, a notable finding considering that this organism is commonly associated with bacterial vaginosis in adults. Vulvar microbiota closely resembled vaginal microbiota but often exhibited additional taxa typically associated with skin microbiota. Our findings suggest that the vaginal microbiota of girls begin to resemble those of adults well before the onset of menarche.

The National Breast and Cervical Cancer Early Detection Program provides funding to tribes and tribal organizations to implement comprehensive cancer screening programs using a program model developed for state health departments. We conducted a multiple-site case study using a participatory research process to describe how 5 tribal programs implemented screening services, and to identify strategies used to address challenges in delivering services to American Indian and Alaska Native women. We analyzed data from semistructured interviews with 141 key informants, 16 focus groups with 132 program-eligible women, and program documents. Several challenges regarding the delivery of services were revealed, including implementing screening programs in busy acute-care environments, access to mammography, providing culturally sensitive care, and providing diagnostic/treatment services in rural and remote locations. Strategies perceived as successful in meeting program challenges included identifying a "champion" or main supporter of the program in each clinical setting, using mobile mammography, using female providers, and increasing the capacity to provide diagnostic services at screening sites. The results should be of interest to an international audience, including those who work with health-related programs targeting indigenous women or groups that are marginalized because of culture, geographic isolation, and/or socioeconomic position.

A 1993 amendment to the authorizing legislation for the Center of Disease Control and Prevention's National Breast and Cervical Cancer Early Detection Program allows direct funding to tribal organizations and urban Native health centers. This study examined tribal programs' implementation of the public education and outreach component utilizing a multisite case study design implemented in partnership with tribal programs. Data were collected from 141 semistructured interviews with key informants and 16 focus groups with program-eligible women. Innovative strategies built on native iconography and personal encounters have encouraged participation and made the programs culturally relevant, providing insights for other communities with little experience in providing early detection services.
