Endometrial carcinoma in high-risk populations: is it time to consider a screening policy?

Endometrial carcinoma (EC) is the leading female genital tract malignancy in industrialized countries. It will become an important public health problem in the coming years in the USA and Europe, where its incidence is increasing, and next-generation interventions should include periodical screening in high-risk women. In this review, we discuss the importance to gynaecologists of detecting women at high risk and offering an adequate screening programme. Screening for EC is particularly challenging and there is currently no proven programme for the surveillance of women estimated to be at an increased risk of developing this form of cancer. The data in the literature, including this and previous issues of Cytopathology, and personal experience suggest that endometrial liquid-based cytology (LBC) might play an essential role in a screening policy for EC. LBC may enable practitioners to reduce age-adjusted mortality for women at high risk for EC.

Role of high molecular weight hyaluronic acid in postmenopausal vaginal discomfort.

AIM: Aim of the present study was to quantify the intensity of vulvovaginal symptoms before and after treatment with high molecular weight hyaluronic acid (HA), to test the tolerability and safety of the product, to evaluate the effect on the quality of life and the compliance to the treatment. METHODS: This was a double-blind randomized placebo-controlled study. In seven months we enrolled 36 post-menopausal women, equally distributed in placebo and active group. The evaluation was based on at least three atrophy-related signs and on the patient reported symptoms. After the written informed consent, the participants were instructed to apply the gel (drug or placebo) daily. Three days after the end of the treatment the patients received a final examination to evaluate the progress of symptoms, the presence of any adverse events and their correlation with the treatment. RESULTS: Self-evaluation scales and investigator evaluation showed that the vaginal dryness was significantly reduced both in placebo and in the active group; however, high molecular weight HA was the only active treatment in reducing significantly itching and burning (P<0.02 and <0.04 respectively). Both treatments significantly reduced vaginal atrophy (P<0.001), erythema (P<0.01 placebo and P<0.001 HA) and vaginal dryness (P<0.001), but HA treatment was significantly more effective on the first two symptoms. Both treatments were very well tolerated and compliance of the treatment was very high. CONCLUSION: High molecular weight HA could be effective in subjective and objective improvement of postmenopausal vaginal atrophy providing a good compliance. No adverse events occurred during the entire period of the study.

[Proteomic applications in gynecology-obstetrics]. / Applicazioni della proteomica in ambito ginecologico-ostetrico.

Proteomics has recently emerged as a powerful approach both for discovering biomarkers as well as for understanding the physiopathology of unclear gynecological-obstetrical disorders. Currently, several biological fluids and fetal tissues were successfully tested, including maternal plasma, amniotic fluid, cervical-vaginal fluid, urine, saliva, placental trophoblast, amnio-chorionic membranes and cord blood. The potential of proteomics on the polycystic ovary syndrome (PCOS) involves biomarkers discovery for a more accurate diagnosis of the syndrome and identification, within the patients with PCOS, those who respond more easily to treatment and those who will be at increased risk for future metabolic complications. The proteomic approach applied to patients with endometriosis would allow not only a non-invasive early diagnosis, but also a staging of the disease and a prediction of infertility risk. Proteomics also involves oncological field, in order to discover biomarkers that allow early diagnosis and prognosis of female genital malignancies. In addition to this, proteomics could be used to understand and predict obstetrical complications such as recurrent spontaneous abortion, preterm birth and preeclampsia. However, further studies are needed on a larger cohort of patients to introduce these biomarkers in clinical practice.

SOPHY project: an observational study of vaginal pH and lifestyle in women of different ages and in different physiopathological conditions. Part I.

AIM: The importance of vaginal pH and vaginal flora in maintaining a well-balanced vaginal ecosystem is well known and has been widely described. However, no systematic nationwide studies have been carried out concerning the correlation between vaginal pH, life style and different physiopathological conditions in women of different ages. METHODS: SOPHY (Study on pH and Hygiene) collected data concerning the lifestyle, vaginal pH, and the presence of symptoms, stratified into different subgroups (prepuberal, fertile, pregnancy, postpartum, premenopause and menopause) in a representative sample of the Italian gynecological population (264 gynaecologists for a total of 2 641 women) with the aid of a specific Internet site for data entry. RESULTS: A more acid vaginal pH was related to a better satisfactory sexual activity and to more healthy genital condition. A positive relationship was detected between education level and good perception of sexuality. Certain clothing habits and a higher frequency of candidiasis and bacterial vaginosis was shown. CONCLUSION: SOPHY revealed some interesting correlations between clothing and the frequency of candidiasis and bacterial vaginosis, between vaginal pH and satisfactory sexual activity, and between education and sexuality. SOPHY had a considerable educational impact, leading the physicians and women to consider vaginal pH as an important aspect of everyday life.

SOPHY project: an observational study of vaginal pH, lifestyle and correct intimate hygiene in women of different ages and in different physiopathological conditions. Part II.

AIM: The first part of the Study on pH and Hygiene (SOPHY) evidenced some interesting correlations between clothing and the frequency of candidosis and bacterial vaginosis, between vaginal pH and satisfactory sexual activity, and between education and sexuality. SOPHY second part explored the effect of intimate hygiene, appropriately chosen within natural plant extracts, according to the women's different ages and conditions, on vaginal pH, candidosis, bacterial vaginosis, and satisfactory sexual activity. METHODS: The second part of the study enrolled 2 641 women randomized into different subgroups (prepubertal, fertile, pregnancy, breastfeeding, premenopause and menopause). The most appropriate detergent for the woman's intimate hygiene was recommended by 264 gynecologists on the basis of age and physio-pathological status of the patients: extract of Salvia officinalis for adolescents, child-bearing age and pre-menopause; extract of Camomilla recutita in menopause; extract of Thymus vulgaris during pregnancy and lactation, and in the presence or risk of vaginal infections. Each product had to be used once or twice a day for four weeks. RESULTS: The natural plant extracts used for intimate hygiene showed a positive clinical effect favouring the reduction of vaginal pH, the improvement of symptoms and the quality of sexual activity in all age/conditions observed. CONCLUSION: SOPHY evidenced that an appropriate intimate hygiene can be an important tool in women's everyday life.

Update on Chlamydia trachomatis.

Chlamydia trachomatis is one the most important sexually transmitted diseases; it can cause serious sequelae despite the absence of symptoms in some people. It's estimated that about 25% of women who have acute salpingitis become infertile, and chlamydial infection is the commonest cause. The introduction of screening programs for its detection are still a topic of discussion. The literature shows that the total cost of examination and treatment of complications known to be associated with genital chlamydial infection (PID, chronic pelvic pain, tubal factor infertility) is generally higher than the total cost of a large-scale Chlamydia screening program. The selection of a diagnostic test for detection of chlamydial genital infection depends on availability, local expertise, and prevalence of Chlamydia trachomatis in the test population. Cell culture is too expensive in nonendemic regions, so the use of non-culture techniques is very attractive. PCR (polymerase chain reaction) and LCR (ligase chain reaction) are actually the two most commonly used alternatives to conventional methods for detecting STD agents. In fact, PCR and LCR have proved useful for detection of Chlamydia trachomatis in cervical and urethral samples both in symptomatic and asymptomatic women. Recently, testing of first-void urine (FVU) specimens with these techniques has shown that the amplification tests are as sensitive as tests with endocervical swab cultures.

Vulvar lichen sclerosus: an immunologic study.

OBJECTIVE: To investigate the seroimmunologic (CD3, CD4, CD8 lymphocytes, C3c and C4 complement fractions, and several autoantibodies) and immunohistochemical (T lymphocyte subpopulations, B lymphocytes, natural killer cells, macrophages, immunoglobulin [Ig] G, Ig M, and C3c complement fraction) characteristics of vulvar lichen sclerosus. METHODS: Serum samples from 68 women with histologically proven lichen sclerosus were compared with those from 53 healthy controls, and tissue samples from 14 of 68 women chosen at random were compared with those from 14 of 53 healthy controls. A scoring system was constructed to compare the number of cells in the tissue. RESULTS: Patients had significantly lower counts of circulating lymphocytes CD3 and CD4 than controls (P < .05) and a higher number of autoantibodies (P < .01). Analysis of the tissue samples confirmed a lower number of CD2 cells (two-tailed P = .002 in epidermis, .005 in dermis), CD3 cells (two-tailed P = .001 in epidermis and in dermis), CD4 cells (two-tailed P = .002 in epidermis, .011 in dermis), and CD8 cells (two-tailed P = .002 in epidermis, .051 in dermis) in subjects than in controls. Numbers of monocyte-macrophage cells were similar in the epidermis but different in the dermis (two-tailed P = .003). No natural killer CD56 cells or B lymphocytes (CD19-CD21) were detected in the affected areas. Deposits of IgG, IgM, and C3 were no greater in biopsy specimens of patients than in those of controls. CONCLUSION: Vulvar lichen sclerosus is not caused by a T cell-mediated response, and a viral origin is unlikely. The absence of CD19 and CD21 cells excludes local production of autoantibodies. Our data do not confirm an autoimmune pathogenesis for vulvar lichen sclerosus but help explain why systemic cortisone is of no benefit and justify the use of petroleum jelly to relieve pruritus.

Epidemiologic characteristics of women with idiopathic recurrent vulvovaginal candidiasis.

OBJECTIVE: To evaluate risk factors related to anamnestic variables, sexual behavior, feminine hygiene habits, and microbiologic findings in women with idiopathic recurrent vulvovaginal candidiasis. METHODS: We conducted a multivariate observational study comparing sociodemographic, anamnestic, clinical, and microbiologic variables between 86 patients with recurrent vaginal candidiasis and 180 controls with nonrecurrent infection. RESULTS: In logistic regression analysis, women with recurrent candidal vaginitis were more likely than controls to use contraceptive pills (adjusted odds ratio 2.0, 95% confidence interval [CI] 1.02-3.91; P = .04) and commercially available solutions for either vulvoperineal cleansing (adjusted odds ratio 2.2, 95% CI 1.25-3.88; P = .007) or vaginal douching (adjusted odds ratio 1.8, 95% CI 1.0-3.26; P = .05). The rate of isolation of non-albicans candida species was significantly higher among cases than controls (adjusted odds ratio 3.0, 95% CI 1.50-6.04; P = .005). Finally, increasing frequency of monthly sexual intercourse was significantly correlated (chi 2 for trend = 4.87; P = .027) with recurrent infection. CONCLUSION: Several behavioral factors seem to influence the occurrence of relapses in recurrent vulvovaginal candidiasis. Appropriate counseling about contraception, sexual activity, and personal hygiene habits could be an important preventive measure in these cases.

A simple method for fallopian tube sperm perfusion using a blocking device in the treatment of unexplained infertility.

OBJECTIVE: To evaluate the efficacy of fallopian sperm perfusion (FSP) using a new method similar to the FAST system in comparison with standard intrauterine insemination (IUI) in patients with unexplained infertility. DESIGN: Prospective, randomized, controlled study. SETTING: Assisted conception service in a University Hospital. PATIENT(S): Women with unexplained infertility undergoing controlled ovarian hyperstimulation (COH). INTERVENTION(S): After hCG administration, patients were randomized to either standard IUI or FSP. The women received the same treatment in the first and all subsequent cycles. A maximum of three cycles was performed. Intrauterine insemination was performed using a standard method, and fallopian sperm perfusion was performed using a commercial device for hysterosalpingography and tubal hydropertubation. MAIN OUTCOME MEASURE(S): Clinical and ongoing pregnancy rates. RESULT(S): A total of 132 cycles was completed: 66 IUI cycles and 66 FSP cycles. In the IUI group, there were 5 ongoing pregnancies, giving a pregnancy rate of 7.6 per cycle and 15.6% per patient; in the FSP group, 14 ongoing pregnancies occurred, giving a pregnancy rate of 21.2% per cycle and 42.4% per patient. The prevalence of multiple pregnancies, miscarriages and ectopic pregnancies was similar in the two insemination groups. Fallopian sperm perfusion was easy to perform, and no case of sperm reflux was observed. The procedure was well tolerated and no complications were observed. The costs were comparable with standard IUI. CONCLUSION(S): In the treatment of couples with unexplained infertility, the method for fallopian sperm perfusion described yields higher pregnancy rates than IUI, with no significant increase in costs or complications. However, these results need to be confirmed in larger studies before replacing IUI with FSP as standard practice.

New perspectives in antibiotic prophylaxis for obstetric and gynaecological surgery.

The goals of antibacterial prophylaxis during obstetric/gynaecological surgery are similar to those of prophylaxis during intra-abdominal surgery. The vaginal flora consists of many aerobic and anaerobic organisms, is dominated by peroxide-producing lactobacilli, and is non-pathogenic under normal conditions. Destabilization of the vaginal ecosystem, as in bacterial vaginosis (BV), causes a massive increase in the ratio of anaerobes to aerobes and is associated with a large increase in the risk of infection. The surgical procedures at most risk of postoperative infection are vaginal, abdominal and radical hysterectomy and caesarean section. Both the American College of Obstetricians and Gynecologists and the American Society of Health-System Pharmacists have recommended single-dose prophylactic protocols using a variety of agents (penicillins, cephalosporins and clindamycin). However, it remains doubtful whether prophylaxis is used widely. In Italy, such prophylaxis has proved less effective in women with BV. Accordingly, patients with confirmed BV are given topical clindamycin for 7 days leading up to surgery, in addition to the usual prophylactic regimen. Caesarean delivery carries a 5- to 20-fold greater risk of infection that normal vaginal delivery. A meta-analysis of 66 clinical studies has shown that any prophylactic regimen is effective in reducing postoperative complications. The use of prophylaxis in patients undergoing a low-risk caesarean section remain controversial.

Assessment of the QoL in Italian menopausal women: comparison between HRT users and non-users.

OBJECTIVES: The aim of this cross-sectional study was to describe QoL in a large sample of women attending menopause centres and compare untreated postmenopausal women and matched HRT users by employing the Women's Health Questionnaire (WHQ) and two generic instruments, the SF-36 and the EQ-5D. METHODS: Overall, 2906 women were recruited by 64 menopause centres throughout Italy, of whom 2160 filled in the questionnaire (1093 on HRT and 1067 not on HRT; response rate: 74%). RESULTS: HRT users tended to be younger, healthier and with shorter menopause duration as opposed to non users, while no major socio-economic differences were present. At multivariate analysis, the presence of chronic diseases, low socio-economic status and living in Southern Italy represented the most important predictors of poor QoL. Furthermore, HRT users showed a lower probability of reporting problems in usual activities and pain/discomfort (EQ-5D), role limitations due to emotional problems (SF-36) and anxiety/fears (WHQ). HRT users also showed highly significant better outcomes in those areas that are more directly attributable to hormonal changes of mid age, namely vasomotor symptoms and sexual problems. CONCLUSIONS: Although QoL is mainly influenced by socio-economic and cultural factors, HRT has the potential for improving not only symptoms, but also more general aspects of physical and psychological well-being of symptomatic postmenopausal women.

Quantitative in situ detection of high-risk human papillomavirus in cytological specimens by SYBR Green I fluorescent labeling.

In this study we developed an in situ protocol for quantitative detection of high-risk human papillomavirus (HPV), based on direct in situ polymerase chain reaction (PCR) with SYBR Green I labeling and GeneAmp 5700 Sequence Detection System technology. This protocol was applied on cytological specimens of patients with cervical intraepithelial neoplasia (CIN) and squamous cell carcinoma (SCC). We performed direct in situ quantitative PCR on cell smears, uninfected human skin fibroblasts, Hela and Caski cells. After in situ amplification, slides were counterstained with propidium iodide and analyzed under a fluorescent microscope in order to localize high-risk HPV and verify preservation of morphology. After PCR optimization, we obtained the following results. The Hela cells showed values ranging from 15 to 33 copies of high-risk HPV per cell, the Caski cell line from 220 to 300 high-risk HPV copies per cell and the cell smear (both CIN and SCC) around 20-35 copies of high-risk HPV per cell. No high-risk HPV amplification was detected in uninfected human fibroblasts, healthy controls, non-amplification control, and non-specific primer control. A positive intranuclear high-risk HPV amplification was detected in cell smears from 20 patients with CIN and 10 with SCC. In conclusion, our in situ quantitative protocol for high-risk HPV detection on cell smears combines both quantitative data and in situ localization of the target, with preservation of morphology. For this reason it could be used as a rapid screening tool when both morphological and quantitative results are requested on the same slide.

Severity of abruptio placentae and neurodevelopmental outcome in low birth weight infants.

The short term neonatal morbidity and 2-year neurodevelopmental outcome were evaluated in 40 low birthweight (< 2500 g) liveborn infants delivered after abruptio placentae and in 80 control infants of similar gestational age. Apgar scores at 1' and 5' were lower in infants born to mothers with severe abruption. The prevalence of intraventricular hemorrhage (Grades I-IV) was 17.5% (7/40) in the cases and 5% (4/80) in the controls (P = 0.035). Cystic periventricular leukomalacia was diagnosed in two cases (5%) and in none of the controls (P = 0.1). At 2-year follow-up, among surviving infants, cerebral palsy (spastic diplegia, hemiplegia or tetraplegia with or without mental retardation) was diagnosed in 11.1% (4/36) of the cases and in none of the 76 controls (P = 0.011). After adjustment by logistic regression analysis for the effect of confounders (gestational age, birthweight, social class and duration of mother's education) the odds ratio of a poor outcome defined as neonatal death or cerebral palsy was 4.4 (95% confidence interval, 1.2-17.0) in index cases as a whole and 8.0 (95% confidence interval, 1.5 to 43.0) in the subgroup of infants born after severe abruption. Mild abruption did not affect the 2-year infant outcome in both univariate and multivariate analysis.

Determinants of different Candida species infections of the genital tract in women. Sporachrom Study Geoup.

OBJECTIVE: We have analyzed the differences in the epidemiological characteristics of women with different Candida low female genital tract infection. STUDY DESIGN: Eligible for the study were 4228 women aged 18-70 years with symptomatic low gynecological tract infection and clinical findings suggestive for Candida infection consecutively attending during the study period first level outpatients gynecological services in Italy. CHROMagar Candida method was used to identify albicans and non-albicans species and among non-albicans ones Candida glabrata, tropicalis and krusei. RESULTS: Out of the 4228 women who entered the study, Candida infection was confirmed by CHROMagar test in 3351 cases (79.3%): Candida albicans was identified in 1431 cases (43%) and non-albicans in 1920. Among the 1920 women with non-albicans infection, Candida glabrata was identified in 1207 women, Candida krusei in 290, Candida tropicalis in 404 (in 19 cases other species or non-specified species were involved). Candida albicans infection was more frequently reported than non-albicans ones in diabetic women (Odds Ratio, OR=1.7, 95%, Confidence Interval, CI 1.1-2.7). Current oral contraceptive users tended more frequently to be infected with Candida albicans than non-albicans, however the estimated OR was only slightly above unity and of borderline statistical significance (OR 1.3, 9.5%, CI 1.1-1.5). Women reporting previous treatment with topic antimicotic reported more frequently non-albicans infection, than Candida albicans ones. However the association was limited and of borderline statistical significance (OR albicans vs. non albicans 0.7, 95% CI 0.5-1.0). Albicans infection was more frequently identified in women whose partner reported symptomatology for Candida infection (OR 1.7, 95% C.I. 1.4-2.0). CONCLUSIONS: This study shows that in this Italian population with symptomatic Candida infection of low female genital tract, there are some differences in the epidemiological characteristics of women with albicans and non-albicans infection.

Coagulation and fibrinolysis changes in normal pregnancy. Increased levels of procoagulants and reduced levels of inhibitors during pregnancy induce a hypercoagulable state, combined with a reactive fibrinolysis.

OBJECTIVE: To establish the physiologic changes in the coagulation and fibrinolytic systems during normal pregnancy and puerperium. STUDY DESIGN: One hundred and seventeen normal pregnant women were investigated in a longitudinal study involving five measurements: blood samples were collected at 10, 20, 30, 36 weeks and on the second day puerperium and were assayed for prothrombin time (PT expressed in INR), activated partial thromboplastin time (PTT), fibrinogen (FBG), antithrombin III activity (AT III), protein C activity (PC), protein S activity (PS), prothrombin fragments 1+2 (F1+2), type 1 plasminogen activator inhibitor activity (PAI) and tissue-plasminogen activator antigen (t-PA). Student t-test, One Way Analysis of Variance (ANOVA) and Bonferroni test were used for statistical analysis. P<0.05 (two tails) was assumed to indicate a significant difference. RESULTS: Fibrinogen concentrations were always increased with respect to controls (P<0.001), while protein S was always decreased, with values averaging 60% of those of controls from the 10th week of pregnancy onwards (P<0.001). Variance analysis showed a statistically significant increase with gestational age for procoagulant factors (INR: P<0.001; FBG: P<0.001), a reduction for anticoagulants (PC: P<0.0001; PS: P<0.0001), and a rise for F1+2 (P<0.0001). With regard to fibrinolysis, there was an increase both for t-PA (P<0.0001) and PAI-1 (P<0.0001) during pregnancy. The t-PA values were always comprised in the normal range. PAI-1 were increased with respect to control values starting from 31st week. The most significant variations in the procoagulants (expressed by PT and FBG) were recorded up to the 20th week (P<0.001); from the 30th week onwards, they remained stable until after the delivery. The same was true for protein S levels (P<0.001), except that the difference between the 10th and the 20th weeks was not statistically significant. The level of F1+2 gradually increased throughout pregnancy (P<0.001), and then fell in the puerperium (P<0.001). CONCLUSIONS: The parameters showing the greatest variation during pregnancy were PT, FBG, PS, F1+2 and PAI-1. The existence of a hypercoagulable state in pregnancy was suggested by the increased levels of F1+2.

The effect of fetal infection with human immunodeficiency virus type 1 on birthweight and length of gestation. SIGO Study Group of HIV Infection in Pregnancy.

We sought to evaluate the effect of vertical transmission of human immunodeficiency virus type 1 (HIV-1) on birthweight and length of gestation. For this purpose we used maternal and pregnancy data of 559 HIV-1-seropositive pregnant women delivered at 13 Italian centers from 1985 to 1991. The mother-to-child transmission rate of HIV infection was 18.2% (84/461). After adjustment for potential confounders with multiple linear regression analysis, there were no differences in birthweight, gestational age, and proportion of expected birthweight (observed birthweight/expected birthweight) between infected and uninfected children. Intravenous drug abuse during current pregnancy was the factor which correlated best with a reduction in birthweight (mean reduction, 214.4 g; 95% confidence interval (CI), 61.7-367.1), length of gestation (mean reduction, 9.3 days; 95% CI, 3.9-14.7) and proportion of expected birthweight (mean reduction, 12.1%; 95% CI, 4.7-19.5%). In our population, HIV-1 infection of the fetus has little effect on length of gestation and birthweight.

Prevalence, diagnosis and treatment of lower genital neoplasia in women with human immunodeficiency virus infection.

The prevalence of lower genital neoplasia and Human Papilloma-virus-related genital lesions were evaluated in a cohort of 75 women with Human Immunodeficiency Virus type 1 (HIV-1) infection at different stages of HIV disease. The overall rate of cervical intraepithelial neoplasia (CIN) in the group studied was 29.3% (22/75). Eight out of 10 high-grade CIN lesions contained 'high-risk' HPV-DNA 16/18 and/or 31/35/51 as demonstrated by 'in situ' hybridization with biotinylated probes. Vulvar and/or perianal condylomata were histologically diagnosed in 14 patients (18.7%); nine of these biopsies contained detectable HPV-DNA which was always related to HPV 6/11. The rate of high-grade CIN in symptomatic HIV-infected patients was 28% (7/25) as compared to 6% (3/50) of the other cases (P = 0.022). CD4 lymphocyte counts, white blood cell counts, CD4+/CD8+ cell ratio and percentage of CD4+ lymphocytes were lower in patients with high-grade CIN in comparison to the patients with negative colposcopical and/or cytological examination. After adequate standard treatment (cryotherapy, electrocauterization, cold-knife conization) only one case of CIN 2 recurred during the 2 years of follow-up period. The prevalence of lower genital neoplasia and HPV-related lesions among HIV-infected women is high and seems to correlate with the severity of HIV disease.

Growth retardation, size at birth and perinatal mortality in twin pregnancy.

The records of 194 consecutive pairs of twins were reviewed. Univariate and multivariate analyses of relative risks (RR) of perinatal death were performed. Perinatal mortality rate was higher in small-for-gestational-age twins and in fetuses with discordancy in size at birth more than 20% and 25%. The RR of perinatal death for small-for-gestational-age twins was 4.8 (2.74-8.42 95% CI). For intertwin birth-weight percent differences of 20% and 25%, the RR was 5.48 (3.2-9.38 95% CI) and 7.2 (3.87-13.42 95% CI). Population mortality attributable risk in the two populations (10.36% and 14.5%, respectively) demonstrates the importance of the prenatal assessment of the respective size of twins in preventing perinatal death.

The urine stream interruption test and pelvic muscle function in the puerperium.

OBJECTIVES: This study assesses the role of the uroflowmetric urine stream interruption test (UST) in the evaluation of postpartum pelvic floor muscle function. METHOD: Two months after vaginal delivery, 492 women who underwent a digital test, vaginal manometry, and a UST were divided into two groups: continent and incontinent. Variables were subjected to the Student's t-test and to Fisher's exact test to verify the difference between the two groups. RESULTS: Digital test and vaginal manometry results were higher in the continent group, but only the UST showed significantly different values (P=0.001). All test results of incontinent puerperae who underwent rehabilitation were significantly improved after treatment. CONCLUSIONS: UST is low cost, non-invasive, and can give objective information about pelvic floor performance after a vaginal delivery. It can be used for both routine clinical use and an outcome measure for women who undergo rehabilitation treatment.
