The role of microbiota in the management of genitourinary syndrome of menopause. Climacteric 2023; 26:353-360. [PMID: 37366082 DOI: 10.1080/13697137.2023.2223923] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2023] [Revised: 05/27/2023] [Accepted: 06/01/2023] [Indexed: 06/28/2023]
Abstract
It is estimated that the 25-50% of women who are reaching menopause every year report symptoms related to the genitourinary syndrome of menopause (GSM). The symptoms are not due simply to lack of estrogen. One possible contributing cause of symptoms is the vaginal microbiota. The vaginal microbiota is a dynamic entity and plays a critical role in the pathogenic interplay of postmenopausal changes. Treatment of this syndrome depends on the severity and type of the symptoms and on the preferences and expectations of women. As there are many treatment options, therapy should be individualized. While new evidence on the role of Lactobacilli in premenopause is emerging, the role of Lactobacilli is still unclear in GSM and the impact of microbiota on vaginal health remains conflictual. However, some reports show promising data on the effect of probiotic therapy in menopause. In the literature there are few studies and small population samples on the role of an exclusive therapy with Lactobacilli and further data will be mandatory. Studies involving large numbers of patients and different intervention periods will be necessary to obtain evidence of the preventive and curative role of vaginal probiotics.

Abstract
Bacterial vaginosis (BV) is the most common cause of vaginal discomfort in women. It is characterised by abnormal vaginal microbiota with a depletion of lactobacilli and predominance of anaerobic microorganisms, mainly Gardnerella vaginalis and Atopobium vaginae. Although antibiotics represent an effective therapeutic option in the short-term, recurrent infections still remain a serious problem. Nowadays, evidence exists about the efficacy of probiotics for the management of BV. The aim of the current double blind, randomised clinical trial was to assess the efficacy of a probiotic mixture, including Lactobacillus acidophilus GLA-14 and Lactobacillus rhamnosus HN001, in combination with bovine lactoferrin, as adjuvant therapy to metronidazole in women with recurrent BV. In particular, normalisation of Nugent score, remission of symptoms and recurrences during a six-months follow-up were assessed. 48 adult women received metronidazole (500 mg twice daily) for 7 days and randomly assigned to take simultaneously either probiotics plus lactoferrin or placebo (2 capsules/day for 5 days followed by 1 capsule/day for 10 consecutive days; induction phase). The verum or placebo administration (1 capsule/day for 10 consecutive days) was repeated each month (maintenance phase) during the six months of follow-up starting the first day of menstrual cycle since the menstrual blood increases the vaginal pH and contributes to increase the risk of recurrences. The results showed that symptoms (vaginal discharge and itching), Nugent score and recurrence rate were significantly improved by probiotics mixture in association with lactoferrin. This alternative approach may represent a safe and effective remedy for the restoration of healthy vaginal microbiota in preventing recurrent BV.

Abstract
Electronic fetal monitoring (EFM) has been introduced in the obstetrics practice as a test to identify the first signs of fetal deterioration, allowing a prompt intervention to reduce neonatal morbidity and mortality. However, results from clinical trials fail to demonstrate a clear benefit with the use of EFM. No decrease in the incidence of cerebral palsy due to intrapartum asphyxia has been achieved and a significant increase in the rate of operative deliveries and in medico-legal litigations has been observed instead. Despite the lack of evidence supporting its safety and effectiveness, this method is routinely used in the clinical practice and periodical updated guidelines to standardize the method of interpretation and proper actions are proposed. However, limitations still exist and the unavoidable consequences are the increasing rate of caesarean delivery, partly due to a defensive attitude in medical choices, and medico-legal litigations for presumed inappropriate evaluation in case of perinatal adverse event. While Obstetrics Societies are trying to "fight" the rise in caesarean section rates, intrapartum EFM tracings are taken in the court proceedings as one of the main evidences in case of adverse event. The aim of this review is to discuss the limitations of guidelines dealing with intrapartum EFM and the pathophysiological basis to assess the suspicious tracings which represent the most observed and critical issue of EFM interpretation.

Lactobacillus plantarum P17630 for preventing Candida vaginitis recurrence: a retrospective comparative study. Eur J Obstet Gynecol Reprod Biol 2014; 182:136-9.

Abstract
BACKGROUND Recurrence is a frequent complaint of patients with vulvovaginal candidiasis (VVC). Although the pathogenesis of VVC remains a controversial issue, disruption of the balance between the vaginal microbiota may facilitate overgrowth by Candida. Some probiotic bacterial strains can suppress Candida albicans; Lactobacillus plantarum P17630 is able to attach to vaginal epithelial cells and significantly reduce the adhesion of C. albicans. OBJECTIVE To evaluate the effect of the application of Lactobacillus plantarum P17630 in restoring the vaginal microbiota and prevention of relapses among women with acute VVC undergoing conventional (azole) local and main therapy. METHODS Retrospective comparative study. We recruited 89 women with a diagnosis of VVC, who were placed into two groups on the basis of reported treatment. The control group was treated with a daily dose of 2% clotrimazole vaginal cream at bedtime for 3 days, followed by vaginal application of a capsule containing lubricant once a day for 6 days and then once a week for another 4 weeks. The probiotic group was treated with the same azole-based protocol but followed by vaginal application of a capsule containing Lactobacillus plantarum P17630 (>10₈ CFU) once a day for 6 days and then once a week for another 4 weeks beginning the day following clotrimazole discontinuation. Clinical and diagnostic patterns were monitored for three months of follow-up. RESULTS At the end of study the probiotic-treated women showed a statistically significant increase in Lactobacillus values "+++" (80% versus 40%, p<0.001) and a better subjective resolution of symptoms such as vaginal discomfort described as burning or itching (90% versus 67.5%, p<0.03). Among controls there was a non-significant increase at 3 months of recurrence of infection, but a significant increase of women with value of pH=5 or >5. CONCLUSION Although the results of different studies are controversial, most have suggested use of probiotics in the prevention or treatment of VVC, and no adverse effects have been reported. Our data with L. plantarum P17630 (Gyno-Canesflor - Bayer) confirm the role of this specific strain as a potential empirical preventive agent for reducing vaginal discomfort after conventional treatment of acute VVC and shifting the vaginal milieu toward a predominance of lactobacilli with an improvement of the vaginal pH value.

Pelvic inflammatory disease (PID) from Chlamydia trachomatis versus PID from Neisseria gonorrhea: from clinical suspicion to therapy. GIORN ITAL DERMAT V 2012; 147:423-430.

Abstract
Pelvic inflammatory disease (PID) is the most significant complication of sexually transmitted infections in childbearing-age women and it represents an important public health problem because of its long-term sequelae (chronic pelvic pain, tubal infertility, ectopic pregnancy). Prior to the mid 1970s PID was considered a monoetiologic infection, due primarily to Neisseria gonorrhea. Now it is well documented as a polymicrobial process, with a great number of microrganisms involved. In addition to Neisseria gonorrhea and Chlamydia trachomatis, other vaginal microrganisms (anaerobes, Gardnerella vaginalis, Haemophilus influenzae, enteric Gram negative rods, Streptococco agalactie, Mycoplasma genitalium) also have been associated with PID. There is a wide variation in PID clinical features; the type and severity of symptoms vary by microbiologic etiology. Women who have chlamydial PID seem more likely than women who have gonococcal PID to be asymptomatic. Since clinical diagnosis is imprecise, the suspicion of PID should be confirmed by genital assessment for signs of inflammation or infection, blood test and imaging evaluation. Laparoscopic approach is considered the gold standard. According to the polymicrobial etiology of PID, antibiotic treatment must provide broad spectrum coverage of likely pathogens. Early administration of antibiotics is necessary to reduce the risk of long-term sequelae.

Abstract
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.

Mannose-binding lectin is produced by vaginal epithelial cells and its level in the vaginal fluid is influenced by progesterone. Mol Immunol 2010; 48:281-6.

Abstract
Mannose-binding lectin (MBL) is a recognition molecule of the complement (C) system and binds to carbohydrate ligands present on a wide range of pathogenic bacteria, viruses, fungi, and parasites. MBL has been detected in the cervico-vaginal cavity where it can provide a first-line defence against infectious agents colonizing the lower tract of the reproductive system. Analysis of the cervico-vaginal lavage (CVL) obtained from 11 normal cycling women at different phases of the menstrual cycle revealed increased levels of MBL in the secretive phase. Part of this MBL derives from the circulation as indicated by the presence of transferrin in CVL tested as a marker of vascular and tissue permeability. The local synthesis of MBL is suggested by the finding that its level is substantially higher than that of transferrin in the secretive phase. The contribution of endometrium is negligible since the MBL level did not change before and after hysterectomy. RT-PCR and in situ RT-PCR analysis showed that the vaginal tissue, and in particular the basal layer of the epithelium, is a source of MBL which binds to the basal membrane and to cells of the outer layers of the epithelium. In conclusion, we have shown that MBL detected in CVL derives both from plasma as result of transudation and from local synthesis and its level is progesterone dependent increasing in the secretive phase of the menstrual cycle.

Abstract
Bacterial vaginosis (BV) is a common condition characterised by a polymicrobial disorder, with an overgrowth of several anaerobic or facultative bacteria and with a reduction or absence of lactobacillus colonisation. The prevalence of BV ranges from 4 to 64%, depending on the racial, geographic and clinical characteristics of the study population. In asymptomatic women, the prevalence varies from 12 to 25%, and similar percentages are observed in pregnant women. Although BV is associated with several adverse outcomes, such as upper genital tract infections, pelvic inflammatory disease, endometritis, preterm birth and low birthweight, many basic questions regarding the pathogenesis of BV remain unanswered. Mucosal immune system activation may represent a critical determinant of adverse consequences associated with BV. An unequal risk for BV acquisition and\or recurrence could derive from different mucosal immune host abilities and\or capability of invading microbes to produce factors that inactivate the local immune response. BV is associated with a two-fold increased risk of preterm birth, with the greatest risk when BV is present before 16 weeks of gestation (odds ratio = 7.55). This may indicate a critical period during early gestation when BV-related organisms can gain access to the upper genital tract and set the stage for spontaneous preterm labour later in gestation. The results of treatment trials for pregnant women with BV have been heterogeneous, with anywhere from an 80% reduction to a two-fold increase in preterm birth among women who received treatment. For this reason, in current clinical practice significant controversy surrounds determining not only who and when to screen but also who and how to treat. Recent evidence shows that individual genetic backgrounds can affect chemokine production. This is an interesting area for future research and could lead to trials of treatment only for women genetically predisposed to preterm birth.

Abstract
AIM With this study, we wanted to evaluate HIV-positive pregnant mothers followed at the HIV Reference Center of Friuli Venezia Giulia and to describe obstetric treatment aimed at identifying vertical transmission factors and at undertaking a correct diagnostic-therapeutic approach to this patient group. The data include a large case series from the European Collaborative Study on HIV in Pregnancy, in which our facility is a collaborating center. METHODS The protocol includes the administration of personalized antiretroviral therapy to seropositive patients at the first visit. An elective caesarean section is performed at 38 weeks gestation. Antiretroviral therapy is continued in the neonate. Breastfeeding is prohibited. RESULTS From 1998 to 2002, 28 pregnant mothers with HIV infection were followed. Most patients came from out of region and had acquired the infection through heterosexual intercourse with a serodiscordant partner. In 1 in 3 patients, a diagnosis of seropositivity was made during pregnancy. One case of vertical transmission was observed. CONCLUSIONS When appropriate prevention measures are instituted, the percentage of vertical transmission of infection can be reduced to less than 1% in Europe today. An important part of this effort is early screening for HIV infection in pregnancy. Other fundamental measures are the institution of antiretroviral therapy starting from the first weeks of pregnancy, monitoring of pregnancy at a tertiary reference center, intravenous administration of therapies before caesarean section, possibly not during labor and with the membrane intact. Equally important factors are neonatal therapy, adequate pediatric monitoring after the infant is born and discontinuation of breastfeeding.

Abstract
In our study we examined the early complement components in patients with bacterial vaginosis (BV), vulvovaginal candidiasis (VVC) and in healthy controls. The levels of C1q, mannose-binding lectin (MBL) and C3 were measured by ELISA in the cervicovaginal lavage (CVL) from gynaecological patients and controls. No significant differences were observed in the levels of these proteins in the three study groups. Immunofluorescence analysis of the clue cells and Candida hyphae from BV and VVC patients for surface-bound complement components showed the presence of C3, while C1q was undetectable. MBL was revealed on clue cells but not on Candida. Binding of MBL to Candida, grown or cytocentrifuged from the CVL of VVC patients, was found to be pH dependent and occurred between pH 4.5 and pH 5.5. In conclusion, we demonstrated that MBL and C3 present in the vaginal cavity act as recognition molecules for infectious agents that colonize the cervicovaginal mucosa. Our finding that MBL, but not C1q, binds to bacteria and fungi in vagina suggests that the lectin and classical pathways of complement activation may play a different role in immune defence in the female genital tract.

Abstract
In order to assess the usefulness of amniotic fluid alpha-fetoprotein (AFP) levels at the time of midtrimester genetic amniocentesis, 4,430 cases were retrospectively studied to compare the high, normal or low AFP values with the karyotype characteristics and fetal anatomy using ultrasound (US) scanning and confirmed by postnatal evaluation or necroscopy in the case of termination of pregnancy. All the cases presenting malformations were correctly diagnosed by US examinations. AFP levels over the 2nd standard deviation (SD) were found in 112 cases (2.52%) and below the 2nd SD in 11 cases (0.24%). The characteristics of these cases are presented and discussed. According to our results, it is concluded that routine assessment of AFP at the time of midtrimester genetic amniocentesis, if coupled with optimal US scanning, is no longer justified.

Abstract
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.

Abstract
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.

Abstract
PURPOSE We investigated the impact of sacral neuromodulation on quality of life and assessed the importance of quality of life for determining the success of sacral neuromodulation in patients with detrusor hyperactivity, including instability and hyperreflexia. We also compared it with parameters documented in a voiding diary. MATERIALS AND METHODS From May 1998 to December 2000, 82 female and 31 male patients 17 to 79 years old (mean age 51.1) with urge incontinence (63), urgency/frequency (5), voiding disturbance (41) and pelvic pain (4) resistant to conservative treatment were enrolled in a national prospective registry after showing a positive response to percutaneous nerve evaluation testing. Of the patients 47 who were 32 to 79 years old (mean age 59.2) with urge incontinence due to detrusor instability and 16 who were 27 to 51 years old (mean age 51.5) with hyperreflexia were asked to complete a validated self-reporting incontinence domain specific quality of life questionnaire before, and 3, 6, 9, 12, 18, 24 and 36 months after implantation. RESULTS Compared with baseline the quality of life index significantly improved at each followup, which strongly correlated with the decrease in the number of incontinence episodes. CONCLUSIONS Evaluating quality of life may be an additional useful tool for assessing the results of sacral neuromodulation for urge incontinence. Our study confirms that sacral neuromodulation is effective therapy for urge incontinence that can have a positive effect on patient quality of life.

Abstract
Vaginal bromocriptine has proven safe and effective in treating hyperprolactinemic women. However, there has been no long-term clinical assessment regarding the influence of daily vaginal bromocriptine administration on the ability to conceive. This article presents two cases of successful pregnancy resulting from this alternative treatment. An infertile woman with an empty sella and hyperprolactinemia was treated with vaginal bromocriptine because of intolerance to oral administration. Prolactin levels were quickly normalized and no side effects occurred. Repeated postcoital tests during treatment proved normal. Twelve months later, the patient conceived. The therapy was discontinued during pregnancy, without complications. Although bromocriptine treatment was not resumed after delivery, postpartum prolactin levels were lower than before treatment and magnetic resonance imaging revealed an unchanged empty sella. Another patient with infertility and pituitary microadenoma with intolerance to oral dopaminergic agonists received the same treatment. Prolactin quickly fell to within the normal range. Vaginal bromocriptine was well tolerated and postcoital test results were not impaired. Tumor regression occurred and 10 months later the patient conceived. Despite bromocriptine withdrawal, no significant complications occurred during pregnancy. It can therefore be concluded that a couple's fertility does not appear to be significantly affected by the persistent local presence of bromocriptine.

Abstract
PURPOSE The Italian Register was created in February 1997 to collect the national results of sacral neuromodulation. All Italian centers at which sacral neuromodulation is performed were invited to participate in our study. We present the results from retrospective and prospective registers. MATERIALS AND METHODS A total of 196 patients underwent permanent implantation of sacral neuromodulation and were enrolled in the Italian register. There were 18 males and 75 females in the retrospective, and 28 males and 75 females in the prospective studies. Student's t test was used to compare paired values, and the Wilcoxon rank sum and nonparametric tests were used when necessary. RESULTS Mean incontinent episodes daily plus or minus standard deviation for patients with detrusor instability went from 5.4 +/- 3.9 to 1.1 +/- 1.6 (median 5 and 0, respectively) at 12-month followup (p <0.001). For idiopathic retention average residual volume decreased from 277 to 108 cc (median 287 and 80, respectively), and 50% of patients stopped catheterization and another 13% catheterized once daily at 1-year after implantation. With neurogenic voiding disturbances, the results fluctuated with time from a minimum of 33% to a maximum 66% of patients who did not catheterize at 6-month followup and 12 months after implantation, respectively. At 12-month followup, 50% of patients with hyperreflexia had less than 1 incontinent episode daily. The problem was completely solved in 66% of patients in the retention group. Of patients in the urge incontinent population 39% were completely dry and 23% had less than 1 incontinent episode daily. CONCLUSIONS Sacral neuromodulation is effective therapy for treating lower urinary tract symptoms resistant to less invasive therapy.

Abstract
OBJECTIVE Our purpose was to examine the efficacy of a topical long-term treatment with boric acid versus an oral long-term treatment (itraconazole) in the cure and prevention of recurrent vulvovaginal candidiasis. STUDY DESIGN A prospective, nonrandomized study of patients affected by recurrent vulvovaginal candidiasis was undertaken. In 3 years we recruited 22 consecutive patients who underwent therapy with itraconazole (group 1) or boric acid (group 2). Women were followed up for 1 year, with clinic and microbiologic controls after 1, 3, 6, and 12 months after the first visit. RESULTS During the treatment, the positive culture results (15.1% vs 12.1%) and the signs and symptoms (33.3% vs. 24.2%) were similar within the 2 groups, with no significant statistical difference. With the withdrawal, after 6 months relapses were common in the 2 groups (54.5%). CONCLUSIONS Boric acid seems to be a valid and promising therapy both in the cure of the vaginal infection and in the prevention of relapses of recurrent vulvovaginal candidiasis, but its efficacy ends with the suspension of the therapy.

Abstract
This prospective, randomized, controlled study compared the effects of recombinant human FSH (r-hFSH) and highly purified urinary FSH (u-hFSH HP) on lipoprotein(a) [Lp(a)] concentrations in women undergoing ovarian stimulation. Fifty infertile women were randomly allocated into two equally sized treatment groups (n = 25 per group). Thirty normal ovulation women were recruited as controls. The infertile women received u-hFSH or r-hFSH 150 IU/day starting on cycle day 2. From cycle day 6 the dose was adjusted according to ovarian response. Human chorionic gonadotrophin 10,000 IU was administered once there was at least one follicle > or =18 mm in diameter. The luteal phase was supported with progesterone 50 mg/day for at least 15 days. Repeated measurements of Lp(a) concentrations were performed during both stimulated and natural cycles. A significant increase in luteal phase Lp(a) concentrations was detected in the stimulated cycles, whereas no significant changes in serum Lp(a) concentrations were observed during natural cycles. There were no significant differences between the urinary and recombinant FSH effects on serum Lp(a). The luteal Lp(a) increase was transitory because after 1 month Lp(a) concentrations returned to baseline values if pregnancy failed to occur; in pregnant women persistent increased Lp(a) concentrations were found at the 8th week. The percentage changes in serum Lp(a) were positively correlated with the luteal progesterone increase (r = 0.40, P < 0.05), but not with follicular or luteal oestradiol increase. The women with low baseline Lp(a) (< or =5 mg/dl) had a greater increase of the Lp(a) concentrations at midluteal phase than women with baseline Lp(a) >5 mg/dl. In conclusion, the recombinant or urinary hFSH administration does not directly influence Lp(a) concentrations. The luteal Lp(a) increase in stimulated cycles is not related to gonadotrophin treatment per se, but appears to be related to the high luteal progesterone concentrations, physiologically or pharmacologically determined. Our results also suggest that the sensitivity to the progesterone changes could be related to apolipoprotein(a) phenotype.

Abstract
BACKGROUND Spinal cord stimulation (SCS) has been shown to be effective in patients with refractory angina and coronary artery disease. No previous study assessed the clinical effects of SCS in patients with refractory angina who present angiographically normal coronary arteries. METHODS SCS was performed in 7 patients (4 men, 3 women, mean age 59.3 +/- 11 years) with refractory angina and normal coronary arteries. Clinical status was assessed 1 month after SCS device implantation and at a mean follow-up of 11 months (range 2-17 months) by: 1) an estimate of the number of anginal attacks and nitrate consumption in the 2 weeks prior to implantation and to follow-up visits; 2) a score of quality of life by a visual analogic scale; 3) a five-item questionnaire assessing effort angina and satisfaction with treatment; 4) treadmill exercise testing. RESULTS At the last follow-up the number of anginal episodes (p < 0.001) and nitrate consumption (p < 0.004) were both reduced by SCS. Visual analogic scale score improved from 2.1 +/- 0.98 to 9.0 +/- 0.9 (p < 0.001) at 1 month and to 6.4 +/- 2.3 (p < 0.01) at the last follow-up. Questionnaire analysis showed that mild (p = 0.006) and moderate (p = 0.000) physical activity, as well as patient satisfaction with anginal status (p = 0.000) and with current treatment (p = 0.000) all improved by SCS. Finally, time to 1 mm ST segment depression, time to angina, and exercise duration were all prolonged by SCS. CONCLUSIONS Our data point out that SCS may considerably improve anginal symptoms and exercise tolerance in a significant number of patients with refractory angina and normal coronary arteries and therefore it should be considered as a valuable treatment option in this group of patients.

Abstract
BACKGROUND Sexually transmitted diseases (STD) have their most incidence in adolescence. We conducted an observational study on the symptomatic patients of our STD's office to evaluate epidemiological distribution, behavioral patterns and diffusion of genital infections in teen-agers in respect of the adult population. METHODS From april 1996 to april 1999 we studied two groups of patients: 54 teen-agers (13-19 years) and 917 women in fertile age (20-40 years). All the patients underwent to a clinical and microbiological examination of vaginal secretions (Gram slide, wet mount, cultures for bacteria, yeasts, eventually Chlamydia trachomatis, Mycoplasma spp, Neisseria gonorrhoeae, Herpes simplex virus--HSV--) and to an anamnestic and socio-epidemiological questionnaire. RESULTS The more frequent genital infections among adolescents was vulvovaginal candidiasis (35% vs. 23.9% of adult people). HSV was found in 1.8% of teen-agers (vs. 0.6%) and when requested, Chlamydia trachomatis and mycoplasmas was found respectively in 16.6% (vs. 1.1%) and 50% (vs. 28%) in adolescents. We observed a high percentage of pregnancy (22.2%) of voluntary pregnancy interruption (41.6%) and a specific sexual behavior among teenagers. CONCLUSIONS Our data show a particular behavioral risk pattern in the adolescence population and indicate the necessity of a serious program of prevention and sexual education that allow young people to live with more consciousness and safety their sexuality.

Abstract
BACKGROUND Adolescence in the age bracket with the highest incidence of sexually transmitted diseases (STDs). An observational study was performed in symptomatic patients attending our Outpatient Clinic for STDs in order to evaluate the diffusion of genital infections in the adolescent population and the different epidemiological distribution compared to adults. METHODS The incidence of these infections was compared in two groups of patients attending the clinic between April 1995 and April 1999. The first consisted of 54 teenagers (13-19 years-old) and the second, used as a control, consisted of 917 women of child-bearing age (20-40 years). All patients underwent clinical examinations and microbiological tests of vaginal secretions (bacterioscopic test on coloured plates using the Gram method, cold tests, cultural assay of bacteria and fungi, assay for (Chlamydia trachomatis, Mycoplasma spp., Neisseria gonorrhoeae, Herpes simplex virus). RESULTS The most common genital infection in teenagers was candidosis (35% vs 23.9%), followed by bacterial vaginosis (31.9% vs 25.8%) and mixed flora vaginitis (25.9% vs 22.6%). HSV was found in 1.8% of adolescents (vs 0.6%), in selected cases, Chlamydia and Mycoplasma were present in 16.6% (vs 1.1%) and 50% (vs 28%) of teenagers respectively. CONCLUSIONS All genital infections were more frequent in the study population of adolescents compared to the control group. The adolescent population should be the target of a serious and systematic programme of prevention in order to ward off the sequelae of early and often irresponsible sexual activity.

Abstract
BACKGROUND Adolescence represents the period with the highest frequency of negative consequences associated with sexual activities (sexually transmitted diseases and unwanted pregnancies). An epidemiological study was carried out in symptomatic patients attending our Outpatient Clinic for Sexually Transmitted Diseases between April 1995 and April 1999 in order to evaluate the behaviour pattern of the adolescent population and identify the differences compared to the adult population. METHODS A questionnaire was used to assess the characteristics of two groups of patients: the first consisted of 54 teenagers (13-19 years-old) and the second, the control group, consisted of 917 women aged between 20 and 40 years old. RESULTS A high percentage of pregnancies (22.2%) and voluntary abortions (41.6%) was observed in teenagers, associated with different sexual behaviours. The age of sexual intercourse was below 15 in 44.4% of adolescents (vs 7.7% of controls), whereas 61.1% had more than one sexual partner and 20.4% had changed partners in the last 6 months (vs 7.4%). 50% of teenagers did not use any method of contraception (vs 44.2%) and barrier methods were only used by 20.4% (vs 18.4%). CONCLUSIONS Our study confirms the existence of a high-risk behavioural pattern in the adolescent population and draws attention yet again to the need for a serious programme of prevention and sexual education which will allow adolescents to experience the discovery of their own sexuality with greater awareness and safety.

Abstract
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.

Abstract
PROBLEM May anti-phospholipid or other autoantibodies interfere with trophoblast-endothelial cells interaction in women with unexplained pregnancy losses? METHODS OF STUDY The sera of 72 women with recurrent spontaneous abortions (RSA) containing antibodies to endothelial cells (28), trophoblast (14), and cardiolipin (10) or lacking antibodies (25), and 26 controls were examined in an inhibition assay of trophoblast adhesion to endothelial cells using an ELISA based on the recognition of trophoblast by antibodies to cytokeratin. RESULTS Adhesion of trophoblast to endothelial cells was time- and dose-dependent. Patients and control sera inhibited trophoblast adhesion with mean values of 37% and 7%, respectively. Inhibition above 2SD of the mean control value was still observed in 58% of the patients sera and 8% of the control sera. Sera containing antibodies to endothelial cells had higher inhibitory effect (38%) than those with antibodies to trophoblast (23%) and cardiolipin (28%) or lacking antibodies (26%). CONCLUSIONS Antibodies and other undefined factors in the sera of women with RSA inhibit adhesion of trophoblast to endothelial cells.

Abstract
AIM A prospective randomized trial was set up to evaluate contractile parameters and quality of life in patients with congestive heart failure. METHODS AND RESULTS We describe the results from 38 patients in sinus rhythm and with chronic heart failure due to congestive cardiomyopathy, prospectively randomized to optimal medical therapy (Group 1, 19 patients) or optimal medical therapy plus dual chamber pacemaker programmed to optimal AV delay (Group 2, 19 patients). At a 6 month follow-up, 7/19 patients in Group 1 had died compared with 5/19 patients in Group 2. During follow-up, there were few significant changes in evaluated parameters except for mitral regurgitation time, which was prolonged in Group 1 and shortened in Group 2. The systolic left ventricular diameter shortened significantly only in Group 2. An energy and activity questionnaire showed that the effect of DDD pacing in the latter patient population was beneficial. CONCLUSIONS From these results we may conclude that at the 6 month follow-up DDD pacing with echo-optimized AV interval programming can improve quality of life without affecting survival.

Abstract
BACKGROUND The effectiveness of cardiac pacing in preventing vasovagal syncope remains controversial. However, DDI pacing with rate hysteresis has been reported to prevent the recurrence of cardioinhibitory vasovagal syncope in up to 35% of affected subjects and to reduce the overall incidence of syncopal episodes in the others. Recently, DDD pacing with a new promising rate drop response function (Medtronic Thera-I model 7960) has become available in clinical practice. AIM OF THE STUDY The aim of the present open trial was to test the effectiveness of this new pacing modality in patients with cardioinhibitory vasovagal syncope. STUDY POPULATION AND METHODS The study population included 20 patients (12 males and 8 females; mean age 61.1 +/- 14 yrs) with recurrent syncope (mean number of prior episode = 6.8, range 5-11) and cardioinhibitory responses during two head-up tilt tests: the first diagnostic and the second during drug therapy with either beta-blockade or etilephrine. The study patients were randomized to receive either DDI pacing with rate hysteresis (8 patients) or DDD pacing with rate drop response function (11 patients). The head-up tilt test performed 1 month after pacemaker implantation was positive in 3 of 12 patients (25%) with DDD pacing with rate drop response function and in 5 of 8 patients (62.5%) with DDI pacing with rate hysteresis. The mean duration of follow-up was 17.7 +/- 7.4 months. During follow-up no patients with a DDD pacemaker with rate drop response function had syncope, while 3 of 8 patients with a DDI pacemaker with rate hysteresis had recurrence of syncope (P < 0.05). CONCLUSIONS These data suggest that DDD pacing with rate drop response function is effective in cardioinhibitory vasovagal syncope and may be preferable to DDI pacing with rate hysteresis.

Abstract
BACKGROUND According to some authors, vaginal delivery always causes denervation of perineum and the greater the damage the longer the second labour phase (the so-called "delivering phase"). Therefore, it is necessary to reduce the number of too prolonged labours, but it is equally important to avoid an uncontrolled increase of cesarean sections. In order to achieve this objective, it is important to carry out a careful selection among laboring women and choose those most at risk for whom cesarean section is strongly recommended. On the basis of the data collected by the medical literature and in consideration of the pathogenetic role of the outlet dystocia, we have tried to identify a simple and effective prognostic index resulting from the different pelvimetric and ultrasonographic parameters. METHODS In 72 full-term pregnant women, we have taken into account the ultrasonographic parameters expressing the fetal dimension (cephalic diameters, cephalic and abdominal circumferences, estimated fetal weight according to Haddlok), the outlet pelvic diameters (trans-ischial and coccygeal-pubic) and a fetal-pelvic index derived from these parameters. RESULTS If taken individually, these parameters do not seem to have any direct connection with the length of the delivering phase, but the combination of the cephalic and external pelvimetric diameters has produced a significative statistical coefficient. CONCLUSIONS On the basis of the data collected, it is suggested that a careful evaluation of external pelvimetric and cephalic parameters would be useful from the clinical point of view.

Abstract
BACKGROUND AND AIMS Given that an increased peripheral insensitivity to insulin represents the primum movens of gestational diabetes, it is reasonable to suppose that the determination and evaluation of the insulinemic response to an oral glucose loading test may represent a simple, effective and low cost screenign test. A method was devised which consisted in performing two assays of insulin and glycemia in venous blood; the first while fasting, the second one hour after the ingestion per os of 50 g glucose. METHODS A group of 79 pregnant women, aged between 20 and 41 years old (mean age 30.5), was tested in around the 23rd week of gestation. All women were attending the Obstetric and Gynecological Clinic at Trieste University. RESULTS Based on the results obtained, insulinemic parameters appear to be significantly correlated with data for the short glycemic curve according to O'Sullivan-Mahan. CONCLUSIONS This study appears to confirm the need to include insulinemic tests as part of the new and more efficacious glucose tolerance tests and to perform prospective studies in order to identify the most reliable screening method in terms of sensitivity and specificity, also in relation to the cost-benefit ratio.

Eligibility criteria for labor induction with prostaglandins. CLIN EXP OBSTET GYN 1997; 24:61-6. [PMID: 9342463] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 02/05/2023]
Abstract
Particular conditions exist at the end of some pregnancies which cause an increase in maternal and fetal risk. A valid alternative for these pregnancies is represented by the administration of prostaglandins, in order to obtain labor induction. The goal of our study was to define the eligibility criteria and the epidemiological characteristics that correlate most with a favorable obstetrical outcome. The study was conducted on 133 informed, consenting patients subjected to labor-induced delivery with prostaglandins E2. The mode of delivery in relationship to parity demonstrated that the pluriparous patients had fewer difficulties in labor and in its induction: of the 43 pluriparous cases, none had a cesarean section for failed induction and 95.3% delivered vaginally. One hundred percent of the patients with a Bishop score of more than 4 went into labor, as opposed to 81% of the patients with a score of less than 4. Therefore, taking into consideration the cost of the method, we retain that choosing an active position is valid, respecting the eligibility criteria for the induction of labor described above.

Abstract
AIMS The aim of this Italian multicentre study was to evaluate the haemodynamic and antiarrhythmic effects of DDIR versus DDI pacing mode in sick sinus syndrome with chronotropic incompetence. METHODS Seventy-nine patients were implanted with a dual chamber rate-responsive pacemaker (Medtronic 7075) and centrally randomised to DDI or DDIR pacing mode. After six months, the pacing modality was crossed over. Follow-up included clinical data, rest ECG, echocardiography, Holter monitoring and exercise testing in DDIR. RESULTS a) Haemodynamic effects. Comparing postimplant exercise testing in DDIR mode with preimplant tests, peak heart rate increased from 96 +/- 17 to 115 +/- 17 bpm (+20%, p < 0.0001), total work capacity from 7.0 +/- 3.5 to 8.8 +/- 4.3 minutes (+26%, p < 0.0001), peak oxygen uptake from 1238 +/- 406 to 1453 +/- 423 ml/min (+17%, p < 0.001) and oxygen uptake at anaerobic threshold from 977 +/- 343 to 1222 +/- 415 ml/min (+25%, p < 0.001). These benefits persisted unchanged during one-year follow-up. b) Antiarrhythmic effects. After six months, paroxysmal atrial fibrillation recurrence significantly decreased in the whole population: group I (DDI) 20.7 vs 48.3%, p < 0.02; group II (DDIR) 21.2 vs 36.4%, p < 0.05; group I + II (DDI + DDIR) 21.0 vs 41.9%, p < 0.001. After one year no significant differences were found between DDI and DDIR. Group I: DDI 23.8 vs DDIR 28.6%, ns; group II: DDI 22.7 vs DDIR 18.2%, ns. CONCLUSION DDIR vs DDI significantly improves short- and long-term haemodynamic performance. Dual chamber pacing shows a significant reduction of paroxysmal atrial fibrillation recurrence, regardless of rate responsiveness.

Abstract
We obtained a series of Escherichia coli strains in which gapA, gapB, or both had been deleted. Delta gapA strains do not revert on glucose, while delta gapB strains grow on glycerol or glucose. We showed that gapB-encoded protein is expressed but at a very low level. Together, these results confirm the essential role for gapA in glycolysis and show that gapB is dispensable for both glycolysis and the pyridoxal biosynthesis pathway.

Abstract
The aim of the study was to evaluate chronic atrial pacing threshold increase after oral propafenone therapy. Fifty patients affected by advanced AV block and sick sinus syndrome were studied at least 6 months after pacemaker implantation, before and after oral propafenone therapy (450-900 mg/day based on body weight). The patients were subdivided into three groups as to the type of electrode implanted, all three unipolar: group I (20 patients) Medtronic CapSure 4003, group II (13 patients) Medtronic Target Tip 4011, group III (17 patients) Medtronic 4057 screw-in leads. In all cases, Medtronic unipolar pacemakers were implanted with the same noninvasive autothreshold measurement method. Propafenone and 5-OH-propafenone blood levels were measured 3-5 hours after drug administration. The packing autothreshold was measured at 0.8, 1.6, and 2.5 V by reducing the pulse width. After propafenone, groups II and III showed a statistically significant threshold rise (P ranging from < 0.01 to 0.05), whereas no significant difference was found in group I. Propafenone and 5-OH-propafenone blood vessels did not show any significant difference among the three groups. Strength-duration curves were drawn for the three groups before and after propafenone: at baseline the curves shifted to the left with the steep part above the knee, clearly favoring CapSure over the other two groups. After propafenone, the curves shifted to the right, with the flat par progressively more evident in groups II and III. In the atrial chamber, steroid-eluting leads prevented threshold increase after propafenone therapy, in contrast with a significant threshold rise with conventional porous and screw-in leads.

Abstract
To evaluate the safety and efficacy of a new algorithm for automatic mode switching (AMS) from DDD-DDDR to DDIR, 26 patients, 16 females and 10 males, mean age 73 +/- 6 years of age, affected by sinus node disease, chronotropic incompetence, and recurrent paroxysmal atrial fibrillation (PAF) received the Medtronic Thera DR pacemaker. The device continuously calculates, in ms, the running average of the intrinsic atrial rate (MAR) and compares the current atrial interval (CAI) with the stored MAR. When the CAI is greater than the MAR it increases by 8 ms, and when the CAI is less than the MAR, it decreases by 23 ms. When MAR < or = 330 ms (182 beats/min), tachycardia is detected and AMS is activated. All patients had clinical evaluation, 12-lead ECG, Holter monitoring, and exercise testing after implantation and every 3 months for 1 year. The results were compared with the data stored in the pacemaker memory: AMS episodes number; the histogram of the last 14 episodes; and atrial electrogram recording. Twenty-two Holter recordings in 13 patients showed PAF and in all of them AMS occurred simultaneously. AMS lasted between 10 seconds and 20 hours, and MAR ranged from 195-400 beats/min. No episode of PAF and no AMS were recorded in 39 Holter recordings in 22 patients. Appropriate AMS was confirmed in five patients by stored atrial electrogram and in nine by 12-lead ECG and pacemaker event markers. Mean atrial sensing was 2.13 +/- 1.04 mV during PAF and 3.18 +/- 1.46 mV during sinus rhythm. No PAF episode and no AMS were recorded during exercise testing. In conclusion, this new algorithm was very reliable, sensitive, and specific.

Abstract
OBJECTIVE To evaluate the prevalence of asymptomatic Chlamydia trachomatis genitourinary infection in women with human immunodeficiency virus (HIV) infection. METHODS The prevalence of asymptomatic chlamydial genitourinary infection in HIV-seropositive women was compared with both HIV-seronegative controls and women with unknown HIV status. Chlamydia trachomatis was isolated in cell culture from endocervical and urethral specimens. RESULTS The prevalence of genitourinary C trachomatis infection among HIV-seropositive women was 18.3% (21 of 115), a rate significantly higher than in both HIV-negative women (11 of 136; P = .016) and controls with unknown HIV status (18 of 326; P = .0001). Crude odds ratios for endocervical and urethral chlamydial infection in HIV-seropositive women compared to HIV-seronegative controls were 2.6 (95% confidence interval [CI] 1.13-6.08) and 3.3 (95% CI 1.15-9.67), respectively. After adjustment for variables related to sexual habits, there was no difference in the risk of cervical C trachomatis infection between HIV-seropositive cases and HIV-seronegative controls (Mantel-Haenszel odds ratio 1.04, 95% CI 0.93-1.14; P = .41). Finally, in HIV-seropositive patients, both the severity of immunosuppression evaluated by CD4+, CD8+, and total lymphocyte counts and the detection of p24 HIV-related antigen did not correlate with the presence of chlamydial infection. CONCLUSIONS Women infected with HIV are at high risk for asymptomatic genitourinary chlamydial colonization. To prevent a possible "epidemic" of pelvic inflammatory disease, appropriate screening programs and therapeutic strategies should be planned.

Abstract
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.

Do steroid-eluting electrodes really have better performance than other state-of-the-art designs? The Italian Multicenter Study Group on Low Output Stimulation.

Abstract
A multicenter study evaluated the performance of atrial and ventricular unipolar leads with porous steroid-eluting and platinized grooved electrodes. A total of 563 leads were implanted in 451 patients. These included 311 ventricular and 97 atrial steroid-eluting electrodes; and 112 ventricular and 43 atrial leads with platinized electrodes. Mean follow-up was > or = 1 year. At implant there were no significant differences in threshold parameters in either chamber. Chronically, however, the steroid-eluting lead consistently had significantly lower pacing thresholds in both chambers. For example, after 360 days implant, steroid-eluting electrodes had 0.23 +/- 0.10 msec ventricular thresholds at 0.8 V compared to 0.45 +/- 0.3 msec in the platinized group (P < 0.0001). In the atrium, the steroid-eluting lead's 6-month thresholds at 0.8 V were 0.15 +/- 0.06 msec compared to 0.9 +/- 0.8 msec for the platinized electrode (P < 0.01). The chronic ventricular QRS amplitudes were significantly greater for the steroid-eluting electrode (P < 0.0005). There were no significant differences in atrial sensing and no incidence of atrial undersensing in the study. The low and consistent thresholds of the steroid-eluting electrodes would have permitted pacing in the ventricle at < or = 2.5 V without compromising safety factor in 99.4% of the patients. The other 0.6% required 5 V temporarily. In the atrium, 100% of the patients could have been paced safely at reduced output. In spite of this, 63% of the implanters lacked the confidence to use reduced outputs.

Abstract
The mean counts of Langerhans' cells were evaluated in cervical biopsies obtained from 30 patients with human immunodeficiency virus (HIV) infection and cervical intraepithelial neoplasia (CIN) and from 30 HIV-seronegative control patients. Each HIV-seronegative control was matched to a seropositive case with respect to grade of CIN, age, and smoking habits. Langerhans' cells were identified by immunohistochemical staining for S-100 protein. In situ hybridization with biotinylated probes was performed to detect human papillomavirus (HPV) DNA 6/11, 16/18, and 31/35/51. The mean counts of S-100 positive cells per 100 basal cells were lower in HIV-seropositive patients than in controls (0.99 +/- 0.08 vs 1.9 +/- 0.2 P = 0.024). These differences occurred independent of any coexisting HPV infection. Positive correlations between S-100 positive cell counts and CD4+ and CD8+ cell counts were found in HIV-infected women. AIDS patients had lower Langerhans' cell counts compared both to patients with AIDS-related complex or asymptomatic HIV infection. Our results suggest that local cervical immunity, as evaluated by Langerhans' cell counts, is impaired in HIV-seropositive women. The severity of impairment seems to correlate with the stage of the HIV disease.
