“…The reporting of abdominal pain suggests trichomoniasis in the upper urogenital tract. (5,6) It is important to emphasize that this sexually transmitted parasite is present in 39% of women with cervical intraepithelial neoplasia, causes infertility in 20% of cases due to tubal adhesion and occlusion, and induces premature birth, low birth weight, postpartum endometritis, stillbirth and death. (5,6) Individuals with trichomoniasis develop massive infiltration of leukocytes and bleeding points in the genital tissues which favors the transmission of the HIV virus.…”

Objective: Evaluate the prevalence and factors associated with trichomoniasis in women receiving primary health care. Methods: A cross-sectional study was developed, involving a sample of 314 medical records, randomly selected through a process of systematic sampling, among women receiving primary health care services. The socioeconomic, demographic and clinical variables were examined. Results: The prevalence of Trichomonas vaginalis was 10.5%, and 35% of the women studied lived in rural areas. The adjusted logistic regression analysis showed that the independent predictors of the presence of trichomoniasis were: high blood pressure, unpleasant vaginal odor and dyspareunia. Conclusion: In terms of practical applicability, the results can provide information for planning new nursing initiatives to prevent and reduce the prevalence of trichomoniasis in women. ResumoObjetivo: Avaliar a prevalência e os fatores associados à tricomoníase em mulheres assistidas na atenção primária. Métodos: Foi desenvolvido um estudo transversal envolvendo uma amostra 314 prontuários, aleatoriamente selecionados por um processo de amostragem sistemática, entre as mulheres atendidas em serviços de atenção básica à saúde. Foram analisadas variáveis socioeconômicas, demográficas e clínicas. Resultados: A prevalência de Trichomonas vaginalis foi de 10,5%, sendo que 35% das mulheres analisadas residiam na zona rural. A análise de regressão logística ajustada mostrou como preditores independentes para a presença da tricomoníase: a elevada pressão arterial, odor vaginal desagradável e dispareunia. Conclusão: A aplicabilidade prática dos resultados refere-se a subsídios para o planejamento de novas ações de enfermagem para a prevenção e redução da prevalência da tricomoníase em mulheres.

“…(6) Despite the estimate that 200 million people are infected every year in the world, (7) the scientific literature shows that there has been a significant decrease in prevalence in some countries. More recent data indicates a prevalence of 13.1% (8) in Brazil, although reporting is still irregular throughout the country.…”

This study identifies the prevalence of vaginal flora alterations in low-risk pregnant women and their association with reported symptoms and gynecological exams. This quantitative, descriptive, cross-sectional study was conducted in public primary care service units Considering undesirable maternal and perinatal outcomes and feasible laboratory practices, the establishment of a routine for diagnosing vaginal flora alterations in low-risk pregnant women is suggested. Los datos apuntan elevada prevalencia de las alteraciones de flora vaginal, con poca asociación a la sintomatología, pero con asociación a hallazgos del examen ginecológico.Considerándose las repercusiones maternas y perinatales indeseables y la práctica de laboratorio ejecutable, se sugiere el establecimiento de rutina para diagnóstico de las alteraciones de flora vaginal en gestantes de bajo riesgo.Descriptores: Vaginosis Bacteriana; Candidíasis Vulvovaginal; Embarazo; Prevalencia. IntroductionBacterial vaginosis (BV) is a relevant issue during pregnancy because it is associated with a higher risk of late miscarriage, infection of the amniotic cavity, premature rupture of membranes, preterm labor, prematurity, and infant low birth weight (1) . The mechanism through which these obstetrical complications occur is not yet totally The metabolism resulting from the proliferation of these bacteria promote increased production of aromatic amines, the putrescine and cadaverine, which evaporate and induce a bad genital odor (6) . Another frequent symptom is a grayish and fluid vaginal discharge with small bubbles (7) .The Lactobacillus SP is a gram-positive bacillus that produces components such as lactic acid, bacteriocins and hydrogen, and which has properties that protect the vaginal flora. These components determine an acidic vaginal pH, lower than 4.5, inhibiting the growth of pathogenic bacteria. The vaginal flora is also composed of other commensal microorganisms, which in certain situations can become pathogenic (8) .We must take into account that under normal Its most common symptoms are itching, urinary discomfort, perineal irritation, and whitish discharge in plates, while between 25% and 40% of women are asymptomatic (10) . Although it is highly prevalent, it is not related to relevant perinatal complications (11) .Vaginal trichomoniasis is an important sexually Based on a prevalence of altered vaginal flora of 20% with confidence interval of 95% and a margin of error of 5%, the sample minimum size was determined by: Patients included in the study were submitted to speculum examination using a bi-valve vaginal Collins speculum, sterilized and without any lubricating.After this procedure, the macroscopic characteristics of the vaginal content were noted, followed by a pH measurement with Merk  tape graduated between four and seven, pressed against the middle third of the lateral vaginal wall for one minute, then proceeding to the reading according to the manufacturer's instructions.Then, the material of the lateral vaginal wall was collected ...

“…Its infection is considered a sexually transmitted disease, which risk factors are the number of sexual partners, socioeconomic status, personal hygiene, not using condoms and their association with other sexually transmitted diseases [21]. In pregnant women it can cause premature rupture of membranes and premature labor [7].…”

Objective: To verify the frequency of Gardnerella vaginalis, Candida sp. Trichomonas vaginalis in pap smears and the presence of these when using the copper intrauterine device or the oral contraceptive. Method:The analysis of 119,312 examinations of women seen by the public health system in the Northeast region of Brazil from the period from January 2006 to December 2010. The variables analyzed were age, frequency of microorganisms, contraceptive use, type of contraception adopted correlated with the presence of microorganisms. Results:The average age among the women was 33.4 ± 11.15 years.The most frequent microorganism, Gardnerella vaginalis, was found in 16,137 examinations, followed by Candida spp. in Trichomonas vaginalis and the 12,661 in 2023. The use of oral contraceptives was found in 21,792 women, and these, showed the presence of Gardnerella vaginalis in 1054, Candida spp. and Trichomonas vaginalis in 687 in 133 tests. Regarding the use of use of copper intrauterine device, used by 18,894 women, the presence of Gardnerella vaginalis was detected in 964, Candida spp. and Trichomonas vaginalis in 595 in 122 of the cases.
