RESUMEN
OBJECTIVE: To identify sociodemographic and clinical variables associated with severe pain with levonorgestrel 52â¯mg intrauterine system (IUS) placement among nulligravid women. STUDY DESIGN: We performed a secondary analysis of a randomized trial that evaluated intracervical anesthesia before IUS insertion. We assessed factors associated with severe pain (visual analog scale pain score ≥7) immediately after insertion using bivariate and multiple regression analyses. RESULTS: Overall, 137/300 (45.7%) subjects reported severe pain. In multiple regression analysis, only intracervical anesthesia [RR 0.55, 95% CI 0.37-0.80] and a history of dysmenorrhea [RR 1.36, 95% CI 1.08-1.72)] were associated with severe pain. CONCLUSIONS: Among nulligravid women, a history of dysmenorrhea increases, and intracervical block decreases severe pain during levonorgestrel IUS insertion. IMPLICATIONS: Dysmenorrhea increases the risk of severe pain at levonorgestrel intrauterine system insertion, while receiving an intracervical lidocaine block decreases this risk. This information can be useful for counseling women prior to device placement and for selecting candidates who may particularly benefit from interventions to reduce pain.

BACKGROUND: Fear of pain during the insertion of intrauterine contraceptives is a barrier to using these methods, especially for nulligravidas. An intracervical block may be easier and more reproducible than a paracervical block; however, this intervention has not been evaluated in nulligravid women to reduce pain with intrauterine contraceptive insertion. OBJECTIVE: To evaluate whether a 3.6-mL 2% lidocaine intracervical block reduces pain at tenaculum placement and levonorgestrel-releasing intrauterine system insertion among nulligravidas; and, in addition, to assess whether the intracervical block has any effect on the ease of device insertion and on the overall experience with the procedure. MATERIALS AND METHODS: In this randomized double-blind controlled trial, nulligravidas were block-randomized to 1 of 3 arms prior to 52-mg levonorgestrel-releasing intrauterine system insertion: 3.6-mL 2%-lidocaine intracervical block, sham injection (intracervical dry-needling), or no intervention. The primary outcome was pain at levonorgestrel-releasing intrauterine system insertion. Secondary outcomes were pain at tenaculum placement, ease of insertion (assessed by healthcare providers), and the overall experience with the procedure (pain with levonorgestrel-releasing intrauterine system insertion compared with expectations, discomfort level, wish to undergo another device insertion in the future, and recommendation of the procedure to others). Participants' pain was measured with a 10-cm visual analogue scale and a 5-point Faces Pain Scale. Pain was summarized into categories (none, mild, moderate, severe) and also analyzed as a continuous variable (mean and 95% confidence interval). Our sample size had 80% power (α = 0.05) to detect a 15% difference in pain score measured by visual analogue scale (mean [standard deviation] visual analogue scale score = 5.9 [2.0] cm) and an absolute difference of 20% in the proportion of women reporting severe pain at levonorgestrel-releasing intrauterine system insertion among groups. We used a χ2 test and a mixed-effects linear regression model. We calculated the number needed to treat for the intracervical block to avert severe pain at tenaculum placement and levonorgestrel-releasing intrauterine system insertion. RESULTS: A total of 302 women were randomized (99 to the intracervical block, 101 to the intracervical sham, and 102 to no intervention), and 300 had a successful device insertion. The intracervical block group had fewer women reporting severe pain than the other groups, both at tenaculum placement (intracervical block: 2% vs sham: 30.2% vs no intervention: 15.2%, P < .0001) and at levonorgestrel-releasing intrauterine system insertion (intracervical block: 26.5% vs sham: 59.4% vs no intervention: 50.5%, P < .0001). The mean (95% confidence interval) pain score reported at levonorgestrel-releasing intrauterine system insertion was lower in the intracervical block group than in the other groups (intracervical block: 4.3 [3.8-4.9] vs sham: 6.6 [6.2-7.0], P < .0001; intracervical block: 4.3 [3.8-4.9] vs no intervention: 5.8 [5.3-6.4], P < .0001). Women from the intracervical block group reported less pain than expected (P < .0001), rated the insertion as less uncomfortable (P < .0001), and were more willing to undergo another device insertion in the future (P < .01) than women in the other groups. The ease of insertion were similar among groups. The number needed to treat for the intracervical block to avert severe pain at tenaculum placement and levonorgestrel-releasing intrauterine system insertion was 2 and 4, respectively. CONCLUSION: A 3.6-mL 2% lidocaine intracervical block decreased pain at tenaculum placement and levonorgestrel-releasing intrauterine system insertion among nulligravidas. It also provided a better overall experience during the procedure.

Thrombotic risk is associated with the estrogen dose and type of progestin in combined oral contraceptives. Studies published since 1990 showed that third-generation progestins have larger risk to contribute to thrombosis development than the second-generation. However, there are conflicts in the literature regarding the thrombotic risk associated to the drospirenone progestin. So, this study aimed to evaluate the effects of 3 formulations of contraceptives containing ethinylestradiol (EE) (20 and 30âµg) combined with drospirenone versus levonorgestrel combined with EE (30âµg) in hemostatic parameters. This cross-sectional study included 70 healthy women between 18 and 30 years, BMI 19 to 30âkg/m², not pregnant, non-smokers, and users or non-users (control) of contraceptives for a minimum period of 6 months. The following parameters were assessed: prothrombin time (PT), Factor VII, activated partial thromboplastin time (aPTT), Factor XII, fibrinogen, Factor 1â+â2, Protein C, Protein S, antithrombin, D-dimers, and plasminogen activator inhibitor-1. Significant alterations were found in PT, aPTT, fibrinogen, D-dimers, and protein S, all favoring a state of hypercoagulation for contraceptive containing DRSP/20EE. Both contraceptives containing DRSP/30EE and LNG/30EE promoted changes that favor the hypercoagulability in the coagulant variable PT and in the anticoagulant variables Protein S and Protein C, respectively. We suggest that the progestin drospirenone can contribute to an inadequate balance among procoagulant, anticoagulant, and fibrinolytic factors, since that the contraceptive containing the lowest dose of estrogen and drospirenone (DRSP/20EE) caused a higher number of hemostatic changes.

Fundamento: Em mulheres pós-menopausadas, mudanças significantes ocorrem, que podem induzir doenças cardiovasculares, tais como o perfil lipídico aterogênico devido a um aumento nos níveis de colesterol total e LDL, e uma diminuição nos níveis de HDL. A terapia de reposição hormonal (TRH) pode evitar essas mudanças no perfil lipídico. Objetivo: Determinar os efeitos da TRH constituída por estradiol transdérmico e acetato de medroxiprogesterona nos parâmetros bioquímicos e lipídicos de mulheres brasileiras pós-menopausadas. Métodos: Este é um estudo prospectivo, longitudinal, aberto, no qual trinta mulheres pós-menopausadas receberam estradiol em gel transdérmico (1 mg/dia) de forma contínua, combinado com acetato de medroxiprogesterona (MPA) (5 mg/dia) por 12 dias/mês. Os seguintes parâmetros foram determinados: colesterol total, triglicérides, lipoproteína de alta densidade (HDL-colesterol), lipoproteína de baixa densidade (LDL-colesterol), lipoproteína de muito baixa densidade (VLDL-colesterol), glicose, aspartato aminotransferase (AST), alanina aminotransferase (ALT), gama-glutamil transferase (GGT) e hormônio folículo estimulante (FSH). Resultados: Os parâmetros do perfil lipídico mostraram uma diminuição não-significante, enquanto os níveis de GGT e FSH apresentaram uma diminuição estatisticamente significante. Conclusões: O tratamento com estradiol em gel transdérmico não mostrou um impacto significante no perfil lipídico, de forma que não resultou em um efeito benéfico nos marcadores de doenças cardiovasculares, sugerindo que a dose, modo de administração e o tempo de tratamento foram importantes para esses resultados. Além disso, o tratamento com dose baixa e modo de administração transdérmico também demonstrou um significante efeito hepático nessa população. Dessa forma, esse tratamento pode fornecer efeitos interessantes sobre o perfil lipídico em mulheres brasileiras pós-menopausadas.
Background: In postmenopausal women, significant changes occur that can induce cardiovascular diseases, such as atherogenic lipid profile, due to an increase in total cholesterol and LDL levels, and a decrease in HDL cholesterol levels. The hormone replacement therapy (HRT) can prevent these changes in lipid profile. Objective: Verify the effects of HRT consisting of transdermal estradiol gel associated with medroxyprogesterone acetate on the lipid profile and biochemical parameters in Brazilian postmenopausal women. Methods: This study is an open prospective longitudinal study, in which thirty postmenopausal women received transdermal estradiol gel (1 mg/day) continuously combined with oral medroxyprogesterone acetate (MPA) (5 mg/day) for 12 days/month. The following parameters were determined: total cholesterol, triglycerides, high density lipoprotein (HDL), low density lipoprotein (LDL), very low density lipoprotein (VLDL), glucose, aspartate aminotransferase (AST), alanine aminotransferase (ALT), gama glutamyl transferase (GGT) and follicle-stimulating hormone (FSH). Results: The parameters of the lipid profile did not show a significant decrease, while the levels of GGT and FSH had a statistically significant decrease. Conclusions: the treatment with transdermal estradiol gel did not have a significant impact on the lipid profile, thus not resulting in a beneficial effect on cardiovascular disease markers, suggesting that the dose, administration route and the time of treatment were important for these results. Moreover, the treatment using small dose and the transdermal administration route also had a significant hepatic effect in this population. Therefore, this treatment might provide interesting effects on the lipid profile in Brazilian postmenopausal women.

Resultados: Los parámetros del perfil lipídico mostraron una disminución insignificante, mientras los niveles de GGT y FSH presentaron una disminución estadísticamente significante. Conclusiones: El tratamiento con estradiol en gel transdérmico no mostró un impacto significante en el perfil lipídico, causando un efecto benéfico en los marcadores de enfermedades cardiovasculares, sugiriendo que la dosis, el modo de administración y el tiempo de tratamiento fueron importantes para esos resultados. Además, el tratamiento con dosis baja y modo de administración transdérmico también demostró un significante efecto hepático en esa población. Así pues, ese tratamiento puede surtir efectos interesantes sobre el perfil lipídico en las mujeres brasileñas posmenopáusicas.

Bacterial vaginosis (BV) is the most prevalent vaginal infection worldwide and is characterized by depletion of the indigenous lactobacilli. Antimicrobial therapy is often ineffective. We hypothesized that probiotic Lactobacillus rhamnosus GR-1 and Lactobacillus reuteri RC-14 might provide an adjunct to antimicrobial treatment and improve cure rates. Sixty-four Brazilian women diagnosed with BV were randomly assigned to receive a single dose of tinidazole (2 g) supplemented with either 2 placebo capsules or 2 capsules containing L. rhamnosus GR-1 and L. reuteri RC-14 every morning for the following 4 weeks. At the end of treatment (day 28), the probiotic group had a significantly higher cure rate of BV (87.5%) than the placebo group (50.0%) (p = 0.001). In addition, according to the Gram-stain Nugent score, more women were assessed with "normal" vaginal microbiota in the probiotic group (75.0% vs. 34.4% in the placebo group; p = 0.011). This study shows that probiotic lactobacilli can provide benefits to women being treated with antibiotics for an infectious condition.

OBJECTIVE: To evaluate the effects of soy isoflavone supplementation on profile lipid and endogenous hormone levels. METHODS: In this double-blind, placebo-controlled study, 47 postmenopausal women 47-66 y of age received 40 mg of isoflavone (n = 25) or 40 mg of casein placebo (n = 22). Cardiovascular risk factors were assessed by evaluating lipid profile at baseline and after 6 mo of treatment. To examine the effects of this regime on endogenous hormone levels, follicle-stimulating hormone and beta-estradiol were measured. Urinary isoflavone concentrations (genistein and daidzein) were measured as markers of both compliance and absorption using high performance liquid chromatography. Baseline characteristics were compared by the unpaired Student's t-test. Within-group changes were determined by paired Student's t-test and comparison between the isoflavone and casein placebo groups were determined by analysis of variance. RESULTS: Lipid levels (low-density lipoprotein and total cholesterol) similarly decreased in both groups. High-density lipoprotein increased significantly in both groups and cannot thus be attributable to treatment; the reason for such variation is unknown and can be attributed to chance or to bias (even that of a real placebo effect in both groups or perhaps in spontaneous changes in exercise and dietary habits of patients after their inclusion). Furthermore, in both groups very low-density lipoprotein and triacylglycerol levels increased in a non-significant manner. CONCLUSION: The results of the present study do not support any biologically significant estrogenic effects of isoflavone on the parameters assessed. Further research will be necessary to definitively assess the safety and efficacy of isoflavone.

Culture-dependent PCR-amplified rRNA gene restriction analysis and culture-independent (PCR-denaturing gradient gel electrophoresis) methodologies were used to examine vaginal lactobacilli from Brazilian women who were healthy or had been diagnosed with vulvovaginal candidiasis (VVC) or bacterial vaginosis. Only Lactobacillus crispatus was detected accordingly by both methods, and H(2)O(2)-producing lactobacilli were not associated with protection against VVC.

OBJECTIVE: We evaluated the effects of soy isoflavone supplementation on hemostasis in healthy postmenopausal women. METHODS: In this double-blinded, placebo-controlled study, 47 postmenopausal women 47-66 y of age received 40 mg of soy isoflavone (n = 25) or 40 mg of casein placebo (n = 22) once a day for 6 mo. Levels of factors VII and X, fibrinogen, thrombin-antithrombin complex, prothrombin fragments 1 plus 2, antithrombin, protein C, total and free protein S, plasminogen, plasminogen activator inhibitor-1, and D-dimers were measured at baseline and 6 mo. Urinary isoflavone concentrations (genistein and daidzein) were measured as a marker of compliance and absorption using high-performance liquid chromatography. Baseline characteristics were compared by unpaired Student's t test. Within-group changes and comparison between the isoflavone and casein placebo groups were determined by a mixed effects model. RESULTS: The levels of hemostatic variables did not change significantly throughout the study in the isoflavone group; however, the isoflavone group showed a statistically significant reduction in plasma concentration of prothrombin fragments 1 plus 2; both groups showed a statistically significant reduction in antithrombin, protein C, and free protein S levels. A significant increase in D-dimers was observed only in the isoflavone group. Plasminogen activator inhibitor-1 levels increased significantly in the placebo group. However, these changes were not statistically different between groups. CONCLUSION: The results of the present study do not support a biologically significant estrogenic effect of soy isoflavone on coagulation and fibrinolysis in postmenopausal women. However, further research will be necessary to definitively assess the safety and efficacy of isoflavone.

OBJECTIVE: To evaluate the impact that administration of transdermal estradiol gel combined with medroxyprogesterone acetate (MPA) has on hemostasis. METHODS: In this open prospective longitudinal study, thirty postmenopausal women received transdermal estradiol gel (1 mg/day) continuously combined with oral MPA (5 mg/day) for 12 days/month. The following parameters were determined: prothrombin time (PT), activated partial thromboplastin time (aPTT), factors VII, X, and XII activity, fibrinogen levels, thrombin-antithrombin complex levels, protein C and S antigen, antithrombin activity, plasminogen activator inhibitor type 1 (PAI-1) antigen, tissue-type plasminogen activator (t-PA) antigen, plasminogen activity and fibrin degradation products (FbDP) antigen. They were evaluated before and after 6 months of treatment. RESULTS: There was a significant decrease in factor VII activity (P=0.001), factor X activity (P=0.016), protein C antigen (P=0.022), antithrombin activity (P=0.025), plasminogen activity (P=0.023), t-PA antigen (P=0.043) and FbDP antigen (P=0.048) compared with baseline values. CONCLUSION: The results suggest that the treatment with transdermal estradiol gel combined with MPA avoids any major activation of coagulation and does not produce any overall effect on fibrinolysis. Therefore, this treatment might provide interesting effects on hemostasis in postmenopausal Brazilian women.

O uso de contraceptivos orais está associado a um risco aumentado de doenças tromboembólicas, o que pode ser explicado pelos seus efeitos sobre o sistema hemostático. Tem sido descrito que o uso de contraceptivos orais promovem alteraçöes pró-coagulantes, e que essas alteraçöes säo acompanhadas dos aumentos da atividade fibrinolítica e dos inibidores naturais da coagulaçäo, o que causaria um restabelecimento do equilíbrio hemostático. O objetivo deste estudo foi avaliar os efeitos do contraceptivo oral contendo 20 ug de etinilestradiol e 150 ug de desogestrelsobre os sistemas de coagulaçäo e fibrinólise. Participaram do estudo 11 voluntárias que foram avaliadas antes e após seis meses de uso do contraceptivo oral. Os parâmetros analisados foram: atividades dos fatores VII, VIII, IX, X e XII (plasmas deficientes em fatores com detecçäo foto-óptica do coágulo), atividades da antitrombina, plasminogênio e a2-antiplasmina (ensaios cromogênicos), quantificaçäo dos antígenos t-PA, produtos de degradaçäo da fibrina e proteínas C e S(ELISA), TP, TTPA e concentraçäo plasmática de fibrinogênico (detecçäo fotoóptica do coágulo). Observamos as seguintes alteraçöes estatisticamente significantes (nível de significância de p<0,05): aumento das atividades dos fatores VIII, IX, X e XII, reduçäo do TTPA, aumento da atividade do plasminogênio, aumento de proteína C e diminuiçäo de proteína S. Com esses resultados sugerimos que o uso do contraceptivo oral testado promove um estado pró-coagulante. Entretanto, os mecanismos de restabelecimento do equilíbrio hemostático näo podem ser garantidos, já que näo observamos alteraçöes suficientes que indiquem isso. Näo observamos aumento nos níveis dos produtos de degradaçäo da fibrina, o que indica que näo ocorreram alteraçöes na gênese e degradaçäo da fibrina. Portanto, sugerimos que o uso do contraceptivo oral pode aumentar o risco de doenças tromboembólicas, principalmente em associaçäo com outros fatores de riscos genéticos e/ou adquiridos.

Foram analisadas 535 histerossalpingografias realizadas entre fevereiro de 1960 e julho de 1977 pelo Departamento de Ginecologia e Obstetrícia da Faculdade de Medicina de Ribeiräo Preto. Säo apresentados os dados referentes às indicaçöes, presença de obstruçöes tubárias, freqüência de malformaçöes e sinéquias uterinas e incompetência istmocervical, assim como os resultados obtidos após os tratamentos instituídos. Conclui-se a histerossalpingografia é um método propedêutico indispensável na avaliaçäo da esterilidade feminina e em algumas patologias ginecológicas, sendo praticamente inócua quando respeitadas as normas básicas da indicaçäo e técnica
