Abstract
Interrelationships among bacteria, protozoa, helminths, and ectoparasites were explored in a cross-sectional survey of 213 pregnant and 99 lactating indigenous women. Prevalences in pregnancy and lactation, respectively, were: vaginitis (89.2%; 46.8%), vaginal trichomoniasis (75.3%; 91.1%), bacterial vaginosis (BV; 60.6%; 63.3%), hookworm (56.6%; 47.8%), asymptomatic bacteriuria/urinary tract infection (AB/UTI; 56.2%; 36.2%), cervicitis (33.3%; 6.3%), vaginal yeast (24.9%; 11.4%), Ascaris (32.5%; 17.4%), vaginal diplococci (20.4%; 31.6%), caries (19.7%; 18.2%), scabies (17.4%; 8.1%), and Trichuris (12.5%; 8.7%). Multiple regressions revealed positive associations during pregnancy (trichomoniasis and AB/UTI; diplococci and Ascaris) and lactation (yeast and scabies). Negative associations were detected in pregnancy (BV and trichomoniasis; hookworm and diplococci) and lactation (BV and yeast). Vaginal Lactobacillus reduced odds of diplococci in pregnancy and lactation, but increased Ascaris eggs per gram (epg) and odds of trichomoniasis in pregnancy and yeast in lactation. These associations raised a concern that treatment of one condition may increase the risk of another.

Abstract
Infections of the lower genital tract associated to maternal and perinatal complications frequently occur during pregnancy. The aim of this study was to evaluate vaginal dysfunction through the analysis of basic vaginal states (BVS) using the methodology of balance of the vaginal content (BAVACO) and to compare it with the microbiological study of candidiasis, trichomoniasis and bacterial vaginosis (BV). Pregnant patients (1238) were examined from 2010 to 2012. In asymptomatic (A) (n: 1046) and symptomatic pregnant women (S) (n: 192) BVS I was 59.5% and 26% of the patients, respectively. BVS II was observed in 19.7% of A and in 17.2% of S. BVS III was only detected in A in 0.4%. BVS IV was observed in 14.4% of A and in 38% of S. BVS V was detected in 6% of A and in 18.8% of S. Yeasts were associated to BVS I and II in 55.5% and 23.2% of A, respectively; and in 32.4% and 31% of S, respectively. Trichomonas were associated to BVS I in 50% of A, to IV in 44.4% of S and to V in 33.3% of S. BAVACO susceptibility to detect yeasts was 80.4% and 85.5% in A and S, respectively; 40% and 75% in A and S, respectively, to detect trichomonas and 100% in A and S to detect BV. BAVACO specificity was 100% for all pathogens in A and S. The study of BVS proved useful as a guide to evaluate vaginal dysfunction, regardless of symptomatology. Therefore, this study is recommended as prenatal control.

Detection of bacterial vaginosis, Trichomonas vaginalis infection, and vaginal Candida infection: a comparative study of methods of extracting exudates, with and without a speculum, during pregnancy. J Low Genit Tract Dis 2006; 9:213-5.

Abstract
PURPOSE To compare the collection of vaginal exudates with and without the use of a speculum to diagnose vaginal infections. MATERIAL AND METHODS We examined 45 patients with vaginal discharge. Two vaginal swabs were taken, one with and the other without a speculum. Both were examined by wet mount microscopy to detect bacterial vaginosis (BV), Trichomonas vaginalis, and the presence of blastospores with or without pseudomycelium. RESULTS A total of 90.9% of patients whose vaginal exudates were negative for BV when extracted with a speculum were also negative in the swab taken without a speculum. In the case of BV-positive exudates using a speculum, the correspondence was 90.5% with the swabs taken without a speculum. Among those exudates obtained with a speculum that were negative for Candida, 92.6% of those obtained without a speculum tested negative. In patients with pseudomycelium, when a speculum was used, 100% also presented a diagnosis of pseudomycelium from the swabs taken without a speculum. A concordance test between the techniques involving the use or nonuse of a speculum was performed for each of the diagnoses showed a good agreement according to the observed Kappa statistics (0.8467 and 0.8396 for BV and Candida, respectively). CONCLUSIONS A very good agreement between the results obtained with and without the use of a speculum was observed. Swabbing without the use of a speculum is especially convenient for pregnant women who require frequent testing for these types of infections during their pregnancies.
