RESUMEN

INTRODUCTION: Monitoring of cerebral autoregulation (CA) in patients with a traumatic brain injury (TBI) can provide an individual 'optimal' cerebral perfusion pressure (CPP) target (CPPopt) at which CA is best preserved. This potentially offers an individualized precision medicine approach. Retrospective data suggest that deviation of CPP from CPPopt is associated with poor outcomes. We are prospectively assessing the feasibility and safety of this approach in the COGiTATE [CPPopt Guided Therapy: Assessment of Target Effectiveness] study. Its primary objective is to demonstrate the feasibility of individualizing CPP at CPPopt in TBI patients. The secondary objectives are to investigate the safety and physiological effects of this strategy. METHODS: The COGiTATE study has included patients in four European hospitals in Cambridge, Leuven, Nijmegen, and Maastricht (coordinating centre). Patients with severe TBI requiring intracranial pressure (ICP)-directed therapy are allocated into one of two groups. In the intervention group, CPPopt is calculated using a published (modified) algorithm. In the control group, the CPP target recommended in the Brain Trauma Foundation guidelines (CPP 60-70 mmHg) is used. RESULTS: Patient recruitment started in February 2018 and will continue until 60 patients have been studied. Fifty-one patients (85% of the intended total) have been recruited in October 2019. The first results are expected early 2021. CONCLUSION: This prospective evaluation of the feasibility, safety and physiological implications of autoregulation-guided CPP management is providing evidence that will be useful in the design of a future phase III study in severe TBI patients.

RESUMEN

While bacterial vaginosis (BV) is a well-known type of vaginal dysbiosis, aerobic vaginitis (AV) is an inflammatory condition that remains understudied and under-recognised. It predisposes women to serious complications including urogenital infections and pregnancy problems. Here, we investigated the bacterial community in AV to explore its possible role in AV pathogenesis. We collected vaginal lavage fluid samples of women (n = 58) classified by wet-mount microscopy as suffering from AV or BV and included an asymptomatic reference group without signs of AV or BV. AV samples showed reduced absolute abundances of bacteria in general and specifically of lactobacilli by qPCR, but 16S rRNA gene sequencing and amplicon sequence variant analysis revealed that Lactobacillus remained the dominant taxon in 25% of the AV samples studied. The other AV samples showed high relative abundances of Streptococcus agalactiae and, unexpectedly, the anaerobes Gardnerella vaginalis and Prevotella bivia in more than half of the AV samples studied. Yet, despite increased relative abundance of these potential pathogens or pathobionts in the AV bacterial communities, the AV samples only slightly stimulated Toll-like receptor 4 and showed reduced activation of Toll-like receptor 2/6, receptors of two pathways central to mucosal immunity. Our findings indicate that the reduced total bacterial abundance with associated enrichment in certain pathobionts in AV might be mainly a consequence of the inflammatory conditions and/or altered hormonal regulation rather than bacteria being a major cause of the inflammation.

RESUMEN

In vitro studies suggest that certain probiotic bacterial strains have potential activity against opportunistic infections such as Candida. There are few in vivo trials using probiotics as a single treatment for acute Candida vulvovaginitis (CV). In this open-label, proof-of-concept study, selected Lactobacillus strains were tested in women with acute Candida vaginitis. Twenty women diagnosed with proven, symptomatic CV were instructed to administer a vaginal probiotic gel with L. plantarum YUN-V2.0, L. pentosus YUN-V1.0 and L. rhamnosus YUN-S1.0 for 10 consecutive days. Vaginal rinsing fluid, vaginal culture swab and vaginal smear for fresh wet-mount microscopy were collected before and 7, 14 and 28 days after start of treatment. On average, participating women were 39 years old and had an history of 5 vaginal infections of which 95% was CV. Nine women (45%) completed the study without the need of rescue medication. Women who needed rescue treatment experienced twice as much Candida infections in the past. A negative correlation was found between the clinical composite score and the time to use rescue medication (R2 = 0.127). Seventy-four per cent of participants found the study gel comfortable to use, and 42% of all women would use the tested gel again for this indication. Forty-five per cent of women were treated successfully for acute CV with a novel vaginal gel containing 3 selected Lactobacillus strains. Patients needing rescue treatment were suffering from more severe and long-standing disease. These results warrant for further testing of this new product, especially of its potential in cases with mild to moderate severity, as an adjuvant to antimycotics or as a preventive measure in women with recurrent vulvovaginal candidosis.

RESUMEN

Vulvovaginal candidosis (VVC) is a common condition with severe symptoms and high recurrence rates. Probiotic lactobacilli are explored as alternatives to azole treatments. Although the vaginal microbiota is generally not depleted in lactobacilli during VVC, studies indicate that the functionality and antimicrobial activity of the lactobacilli is impaired. We selected three strains from the Lactobacillus genus complex (L. rhamnosus GG, L. pentosus KCA1 and L. plantarum WCFS1) based on in vitro evaluation and formulated them in a gel for vaginal application. This gel was evaluated in 20 patients suffering from acute VVC, who were followed for four weeks including a 10-day treatment period. The microbiome was assessed through 16S rRNA (bacteria) and internal transcribed spacer (ITS; fungi) amplicon sequencing, supplemented with quantitative PCR, culture and microscopy for Candida evaluation. 45% of women did not require rescue medication (3×200 mg fluconazole), implying an improvement of their symptoms. These women showed similar end concentrations of fungi as women treated with fluconazole. Moreover, fluconazole appeared to reduce numbers of endogenous lactobacilli. Our study points towards important aspects for future selection of lactobacilli for probiotic use in VVC and the need to investigate possible negative influences of azoles on the vaginal bacterial community.

RESUMEN

BACKGROUND: It is commonly stated that Candida in the vagina prefers a low pH to develop infection. However, mixed infections of Candida with bacterial vaginosis (BV) and aerobic vaginitis (AV) are rather common and may challenge the rule that Candida should only be looked for in low vaginal pH settings. In this study we tested whether the vaginal pH in acute vaginal candidosis is lower than in women successfully treated to prevent Candida recurrences. METHODS: Vaginal pH and microscopy findings of vaginal microbiota were recorded during 12 visits over 1.5 years in 117 patients medically monitored during a degressive fluconazole maintenance regimen for proven recurrent vulvovaginal candidosis (ReCiDiF trial). The fluctuation of the mean pH of and microscopic findings of the vaginal smears were studied before, during and after the treatment. RESULTS: The mean vaginal pH of women with acute infection before or after ending maintenance treatment was (4.7±0.8 and 4.8 ±1.0, respectively, p>0.05). During maintenance treatment with fluconazole, the pH dropped significantly to 4.5±0.8 (p=0.01). Depression of Lactobacilli spp. (increased lactobacillary grades) was more frequent during the acute, pre-treatment period (30.0%) than during the treatment period (23.1%, p=0.03). Aerobic vaginitis type flora was also more prevalent pre-treatment than during treatment (30.0% vs 22.2%, OR=0.7 (95%CI 0.5-0.9), p=0.01). DISCUSSION: In women with RVVC, acute vaginal Candida infection is associated with an increased pH, and disturbed vaginal bacterial microbiota. During fluconazole maintenance treatment, the pH drops to normal levels and the lactobacillary grade improves. CONDENSATION: Acute Candida vulvovaginitis can be associated with a disturbance of the vaginal microbiota. In patients with recurrent vulvovaginal candidosis, decrease of pH, and increase of Lactobacilli spp. were observed during fluconazole maintenance treatment. This pH drop was seen in all response groups. This contradicts the common belief that active vaginal Candida infection is related to low pH.

RESUMEN

INTRODUCTION: Despite its frequency, recognition and therapy of vulvovaginal atrophy (VVA) remain suboptimal. Wet mount microscopy, or vaginal pH as a proxy, allows VVA diagnosis in menopause, but also in young contraception users, after breast cancer, or postpartum. Intravaginal low dose estrogen product is the main therapy. Ultra-low-dose vaginal estriol is safe and sufficient in most cases, even in breast cancer patients, while hyaluronic acid can help women who cannot or do not want to use hormones. AREAS COVERED: The authors provide an overview of the current pharmaceutical treatment for vulvovaginal atrophy and provide their expert opinions on its future treatment. EXPERT OPINION: The basis of good treatment is a correct and complete diagnosis, using a microscope to study the maturity index of the vaginal fluid. Minimal dose of estriol intravaginally with or without lactobacilli is elegant, cheap and can safely be used after breast cancer and history of thromboembolic disease. Laser therapy requires validation and safety data, as is can potentially cause vaginal fibrosis and stenosis, and safer and cheaper alternatives are available.

RESUMEN

BACKGROUND: Because of its increasing prevalence worldwide, its sexual transmissibility and its facilitation of human immunodeficiency virus transmission, Trichomonas vaginalis (TV) infection constitutes an important public health concern. THE AIM OF THE STUDY: While searching for possible resistant TV cases, adequacy of management of TV-infected women was assessed. METHODS: Cervical cytology between July 2007 and July 2014 was tested with TV polymerase chain reaction, and 304 women expressed repeatedly positive results, 718 in total. For each of these positive results, a questionnaire about treatment decisions was sent to the 182 Belgian physicians treating these women. RESULTS: From the 346 returned questionnaires by their physician it was evident that 58.1% of women with repeatedly positive TV had received no treatment. TV was overlooked in 31.5%, and in 17.6% the test result was seen but ignored. Upon seeing the positive result, 23.9% of physicians decided that this finding was not important enough to institute treatment, and/or requested confirmatory tests. Adequate treatment was prescribed in 38.4%. Retreatment after failed therapy was given in only 29.3% of the cases. And 60% of the partners of women with persistent TV infection were not traced, nor treated. CONCLUSION: Most of the repeatedly positive TV infection may not be due to antibiotics resistance. The low awareness, poor attention, failure of contact tracing, and low rates of proper treatment provided by treating physicians question the adequacy of the current management of TV infection and requires renewed education campaigns and increased surveillance.

RESUMEN

OBJECTIVE: Although most women on fluconazole maintenance therapy for recurrent vulvovaginal candidosis experience a substantial improvement in quality of life, some do not respond to therapy. Is candidal colonization of extragenital sites related to suboptimal response to maintenance therapy? PATIENTS AND METHODS: Women included in a multicenter follow-up study (ReCiDiF) were evaluated for clinical signs and presence of yeasts in nose, mouth, anus, perineum, and urine. Candida was diagnosed by positive microscopy, confirmed by positive culture or polymerase chain reaction. After treatment, women were divided into groups according to their response to a fluconazole maintenance regimen (optimal, suboptimal, and nonresponders). RESULTS: The most frequent extravaginal Candida spp. were detected in urine (79.5%), perineum (78.6%), and anus (56.4%). Carriers of Candida in the mouth were more likely to have it in the anus (OR 3.2; 95% CI 1.4-7.7). Colonization in anus (OR 3.3; 95% CI 1.3-8.1) or in multiple extravaginal sites (OR 3.0; CI95% 1.2-7.4) was related to nonresponse to therapy. Candidal carriage in the anus did not increase anal and perianal symptoms. CONCLUSION: Women with anal carriage and multiple-site candidal colonization are less likely to respond to individualized decreasing dose fluconazole therapy.

RESUMEN

OBJECTIVE: This study analyses a relation between sexual habits and the presence of Candida in extra-genital locations as well as a potential effect on therapy response. MATERIAL AND METHODS: Candida cultures were obtained from mouth, nose, anus, urine and perineum of 117 women enrolled in a RVVC treatment trial (ReCiDiF). Sexual behaviour and carriage rates of extra-genital Candida of women responding well to treatment were compared to that of non-responders. RESULTS: Most respondents were heterosexual. All but one practiced vaginal sex. Regular receptive oral sex was not related to multiple site colonisation with Candida (OR = 1.27; CI95% 0.36-4.48), nor to non-response to therapy (OR = 1.3; CI 95% 0.41-4.73). Also, masturbation was not related to response to therapy (OR 0.8; CI95% 0.31-1.84), nor was anal sex (OR = 0.54; CI95% 0.11-2.72). CONCLUSION: Neither oral nor casual anal sex, nor masturbation can be held responsible for the association of the multiple site/anal colonisation with Candida and inferior response to fluconazole maintenance therapy. Changing sexual behaviour during fluconazole maintenance treatment for RVVC in otherwise healthy women should not be advocated. Also, treatment of asymptomatic sexual partners of women with RVVC is not recommended.

RESUMEN

Localized provoked vulvodynia (LPV) causes introital dyspareunia in up to 14% of premenopausal women. Vaginal infections like candidosis may play a initiating role. The aim of this study was to test a possible association of vaginal microbiota alternations such as Candida vaginitis (CV), aerobic vaginitis (AV) and bacterial vaginosis (BV) with severity of vulvodynia and painful intercourse. In an observational study, Q-tip touch test (score 1 (no pain) to 10 (worst possible pain)) was performed on seven vestibular locations in 231 LPV patients presenting in the Vulvovaginal Disease Clinics in Tienen, Leuven and Antwerp, Belgium. Severity of pain upon attempting sexual intercourse was recorded in a similar scale. Both scales were compared to results from fresh wet mount phase contrast microscopy on vaginal fluid smears tested for abnormal vaginal flora (AVF), BV, AV and CV according the standardized microscopy method (Femicare). Fisher's exact test was used. Average age was 31.3 ± 11.6 years, and 58.8% (n = 132) had secondary vestibulodynia. There was an inverse relation between the presence of Candida in the vaginal smears and pain score (p = 0.03). There was no relation of pain score, nor Q-tip score with BV. LPV patients with Q-tip score above 7 at 5 and/or 7 o'clock or at 1 and/or 11 o'clock had more often AV than women with lower pain scores (30 vs 14.5%, p = 0.01, and 39 vs 14.7%, p < 0.005, respectively). Detailed study of the vaginal microflora in patients demonstrates that the most severe patients suffer more from AV and less from Candida. These abnormalities need to be actively looked for and corrected before considering surgery or other therapies.

RESUMEN

PROBLEM: Is sensitization to atopic reaction related to treatment response of recurrent Candida vulvovaginal (RVVC)? METHOD OF THE STUDY: Analysis of ReCiDiF trial data of optimal (OR) and non-responders (NR) to fluconazole maintenance treatment, to explore medical history, physical status, family history, and vaginal immune response for potential sensitization to atopic reaction. RESULTS: Sociodemographic characteristics of 33 NR women were not different from 38 OR. NR had received higher number of different treatments (mean difference 1.6 different treatments (95% CI: 0.20-2.97), P = .03) and had more episodes of disease (P < .05). Multivariate regression analysis showed that family history of atopy (OR: 4.9, CI 95%: 1.1-22.2), duration of symptoms (OR: 1.2, CI 95%: 1.02-1.5), and vulvar excoriation (OR: 3.6, CI 95%: 1.4-9.3) were related to non-response. Vulvar excoriation at entry was the only statistically significant predictive factor for non-response in multivariate analysis with specificity 77.8% and sensitivity 51.6%. CONCLUSION: Women with RVVC with vulvar excoriation, longer duration of disease, and family history of atopic disease are at increased risk not to respond to maintenance fluconazole treatment.

RESUMEN

Objective: To characterize the vaginal microbiome and the rate of sexually transmitted infections (STIs) in the women of Príncipe (São Tomé and Príncipe). Methods: Cross-sectional study of 100 consecutive women, invited for a free appointment and cervical cancer screening. A vaginal slide (wet mount microscopy) and a cervical sample (ThinPrep®) (Pap test, high risk human papillomavirus [HR-HPV], N. gonorrhea [NG], T. vaginalis [TV], and C. trachomatis [CT]) were obtained. Results: TV, NG, CT, and HIV were found in 8.0%, 2.0%, 3.0%, and 2.0%, respectively, and were more prevalent in younger women. HR-HPV was positive in 36.7%; 2 were positive for HPV18, but none for HPV16. Coinfection of HPV with other STIs was 8.3%. Prevalence of abnormal vaginal flora (AVF) was 82.5%, mostly bacterial vaginosis (BV) 54.6%, and moderate/severe aerobic vaginitis (msAV) 25.8%. HR-HPV was not related to BV (p = 0.67). The association of abnormal Pap test with msAV was not significant (p = 0.08). Conclusion: The prevalence of NG, CT, TV, and HR-HPV was according to expected, while that of HR-AVF was higher. The surprisingly low prevalence of HPV16 and HPV18 must be considered in the design of programs for prevention and vaccination; this setting can be useful as a model for postvaccination scenarios.

RESUMEN

Aerobic vaginitis (AV) is the name given in 2002 to a vaginal infectious entity which was not recognized as such before. It is characterized by abnormal (dysbiotic) vaginal microflora containing aerobic, enteric bacteria, variable levels of vaginal inflammation and deficient epithelial maturation. Although AV and bacterial vaginosis (BV) share some characteristics, such as a diminished number or absence of lactobacilli, increased discharge (fishy smelling in BV, while in severe forms of AV, a foul, rather rotten smell may be present) and increased pH (often more pronounced in AV), there are also striking differences between the two. There is no inflammation in women with BV, whereas the vagina of women with AV often appears red and edematous, and may even display small erosions or ulcerations. The color of the discharge in BV is usually whitish or gray and of a watery consistency, whereas in AV it is yellow to green and rather thick and mucoid. Women with BV do not have dyspareunia, while some women with severe AV do. Finally, the microscopic appearance differs in various aspects, such as the presence of leucocytes and parabasal or immature epithelial cells in AV and the absence of the granular aspect of the microflora, typical of BV. Despite all these differences, the distinction between AV and BV was not recognized in many former studies, leading to incomplete and imprecise diagnostic workouts and erroneous management of patients in both clinical and research settings. The prevalence of AV ranges between 7 and 12%, and is therefore less prevalent than BV. Although still largely undiagnosed, many researchers and clinicians increasingly take it into account as a cause of symptomatic vaginitis. AV can co-occur with other entities, such as BV and candidiasis. It can be associated with dyspareunia, sexually transmitted infections (such as human papilloma virus, human immunodeficiency virus, Trichomonas vaginalis and Chlamydia trachomatis), chorioamnionitis, fetal infection, preterm birth and cervical dysplasia. Many other possible pathological associations are currently under investigation. The diagnosis of AV is made using wet mount microscopy, ideally using phase contrast. An AV score is calculated, according to: lactobacillary grade, presence of inflammation, proportion of toxic leucocytes, characteristics of the microflora and presence of immature epithelial cells. To circumvent the hurdle of microscopic investigation, some groups have begun to develop nucleic-acid-based and enzymatic diagnostic tests, but the detailed information obtained with phase contrast microscopy is irreplaceable. The best treatment is not yet fully determined, but it must be tailored according to the microscopic findings and the patient's needs. There is a role for local estrogen therapy, corticosteroids, antimicrobials and probiotics. Further research will reveal more precise data on diagnosis, pathogenesis, management and prevention.

RESUMEN

Is non-response to maintenance treatment for recurrent vulvovaginal candidosis (RCVV) related to the impaired glucose metabolism? In the ReCiDiF trial, women with RCVV were given a degressive regimen with fluconazole according to their clinical, microscopic and mycologic response. Data obtained from optimal, suboptimal and non-reponding patients were used for secondary analysis of medical history, physical status and family history for potential glucose impairment. Results were presented in means and percentages. Pearson chi-square, Fisher exact, Mann-Whitney U, Kruskal-Wallis and Spearman's correlation coefficient was calculated. P<.05 were interpreted as statistically significant. Sociodemographic characteristics and family and personal history of diabetes were not different between optimal, suboptimal and non-responders. The average HbA1c concentration was 5.1±0.3% in optimal, 5.0±0.4% in sub-optimal, and 5.1±0.3% in non-responding patients (P=1.0). There are no statistical differences between optimal, sub-optimal and non-respondents to treatment in all deciles of HbA1c among patients with recurrent candidosis (P=1.0). There was no difference among groups in fasting glucose concentration, nor after 30 min, 60 min or 120 min during the oral glucose tolerance test (OGTT) (P=.6). Area under the OGTT curve did not differ within groups (P=.8), nor was the deviation from the normal cut-off value any different (P=.8). Glucose concentration in vaginal rinsing fluid showed no correlation with responsiveness to treatment (P=.7). Glucose metabolism, BMI, personal or family history of diabetes are not related to non-response to maintenance treatment with fluconazole for patients with RVVC.

RESUMEN

Mycoplasmata have been linked to pregnancy complications and neonatal risk. While formerly a limited number of species could be discovered by cultures, molecular biology nowadays discovers both lower quantities and more diverse species, making us realize that mycoplasmata are ubiquitous in the vaginal milieu and do not always pose a danger for pregnant women. As the meaning of mycoplasmata in pregnancy is not clear to many clinicians, we summarized the current knowledge about the meaning of different kinds of mycoplasmata in pregnancy and discuss the potential benefits and disadvantages of treatment. Currently, there is no general rule to screen and treat for mycoplasmata in pregnancy. New techniques seem to indicate that Ureaplasma parvum (Up), which now can be distinguished from U. urealyticum (Uu), may pose an increased risk for preterm birth and bronchopulmonary disease in the preterm neonate. Mycoplasma hominis (Mh) is related to early miscarriages and midtrimester abortions, especially in the presence of abnormal vaginal flora. Mycoplasma genitalium (Mg) is now recognized as a sexually transmitted infection (STI) that is involved in the causation of cervicitis, pelvic inflammatory disease (PID) in non-pregnant, and preterm birth and miscarriages in pregnant women, irrespective of the presence of concurrent other STIs, like Chlamydia or gonorrhoea. Proper studies to test for efficacy and improved pregnancy outcome are scarce and inconclusive. Azythromycin is the standard treatment now, although, for Mg, this may not be sufficient. The role of clarithromycin in clinical practice still has to be established. There is a stringent need for new studies based on molecular diagnostic techniques and randomized treatment protocols with promising and safe antimicrobials.

RESUMEN

OBJECTIVE: Is self-assessed vaginal pH measurement to detect abnormal vaginal bacterial microflora (AVF) an adequate prescreening method for detection of genital sexually transmitted infections (STIs)? MATERIALS AND METHODS: A total of 360 Ugandan women tested themselves with a gloved finger and a pH color strip. PCR for bacterial vaginosis (BV)-associated bacteria was tested by PCR for Mycoplasma hominis, Ureaplasma urealyticum, and/or Atopobium vaginae, while the STIs were diagnosed by positive PCR for Chlamydia trachomatis, Neisseria gonorrhoeae, Mycoplasma genitalium, and/or Trichomonas vaginalis. RESULTS: A strong correlation was found between self-assessed pH values and BV-associated bacteria (P<0.0001), but not with STIs, not as single infections, nor in general. CONCLUSION: Self-measured vaginal pH correlated well with markers of high-risk microflora types such as BV or aerobic vaginitis, but not with STIs. Hence, in a screening program addressing AVF in low-resource countries, extra specific tests are required to exclude STIs.

RESUMEN

Aerobic vaginitis (AV) is a vaginal infectious condition which is often confused with bacterial vaginosis (BV) or with the intermediate microflora as diagnosed by Nugent's method to detect BV on Gram-stained specimens. However, although both conditions reflect a state of lactobacillary disruption in the vagina, leading to an increase in pH, BV and AV differ profoundly. While BV is a noninflammatory condition composed of a multiplex array of different anaerobic bacteria in high quantities, AV is rather sparely populated by one or two enteric commensal flora bacteria, like Streptococcus agalactiae, Staphylocuccus aureus, or Escherichia coli. AV is typically marked by either an increased inflammatory response or by prominent signs of epithelial atrophy or both. The latter condition, if severe, is also called desquamative inflammatory vaginitis. As AV is per exclusionem diagnosed by wet mount microscopy, it is a mistake to treat just vaginal culture results. Vaginal cultures only serve as follow-up data in clinical research projects and are at most used in clinical practice to confirm the diagnosis or exclude Candida infection. AV requires treatment based on microscopy findings and a combined local treatment with any of the following which may yield the best results: antibiotic (infectious component), steroids (inflammatory component), and/or estrogen (atrophy component). In cases with Candida present on microscopy or culture, antifungals must be tried first in order to see if other treatment is still needed. Vaginal rinsing with povidone iodine can provide rapid relief of symptoms but does not provide long-term reduction of bacterial loads. Local antibiotics most suitable are preferably non-absorbed and broad spectrum, especially those covering enteric gram-positive and gram-negative aerobes, like kanamycin. To achieve rapid and short-term improvement of severe symptoms, oral therapy with amoxyclav or moxifloxacin can be used, especially in deep dermal vulvitis and colpitis infections with group B streptococci or (methicillin resistant) Staphylococcus aureus. Since the latter colonizations are frequent, but seldom inflammatory infections, we in general discourage the use of oral antibiotics in women with AV. In cases with a severe atrophy component (more than 10 % of epithelial cells are of the parabasal type), local estrogens can be used; and in postmenopausal or breast cancer patients with a contraindication for estrogens, even a combination of probiotics with an ultra-low dose of local estriol may be considered.

RESUMEN

OBJECTIVE: Is it feasible to learn the basics of wet mount microscopy of vaginal fluid in 10 hours? MATERIALS AND METHODS: This is a pilot project wherein 6 students with different grades of education were invited for being tested on their ability to read wet mount microscopic slides before and after 10 hours of hands-on training. Microscopy was performed according to a standard protocol (Femicare, Tienen, Belgium). Before and after training, all students had to evaluate a different set of 50 digital slides. Different diagnoses and microscopic patterns had to be scored. κ indices were calculated compared with the expert reading. RESULTS: All readers improved their mean scores significantly, especially for the most important types of altered flora (p < .0001). The mean increase in reading concordance (κ from 0.64 to 0.75) of 1 student with a solid previous experience with microscopy did not reach statistical significance, but the remaining 5 students all improved their scores from poor performance (all κ < 0.20) to moderate (κ = 0.53, n = 1) to good (κ > 0.61, n = 4) concordance. Reading quality improved and reached fair to good concordance on all microscopic items studied, except for the detection of parabasal cells and cytolytic flora. CONCLUSIONS: Although further improvement is still possible, a short training course of 10 hours enables vast improvement on wet mount microscopy accuracy and results in fair to good concordance of the most important variables of the vaginal flora compared to a reference reader.

RESUMEN

OBJECTIVE: The aim of the study was to evaluate the diagnostic value of Nugent score, wet mount microscopy, and polymerase chain reaction (PCR) test developed in Russia for bacterial vaginosis (BV) diagnosis. MATERIALS AND METHODS: One hundred Caucasian women were enrolled in this study. Three vaginal samples were taken from each participant: 1 for PCR analysis, 1 for Nugent score evaluation, and 1 for wet mount microscopy. The smears for microscopy were air-dried and sent to Femicare, Tienen, Belgium, for blinded analysis by microscopy. Multiplex real-time PCR was performed using primers and probes targeting Gardnerella vaginalis, Atopobium vaginae, Lactobacillus species, and total quantity of bacterial DNA (16SrRNA gene). RESULTS: Agreement among the 3 methods was 72 (73.5%) of 98 samples. Agreement between Nugent score and PCR results was 77 (78.6%) of 98 samples; between wet mount microscopy and PCR, 81 (82.65%) of 98 samples; between wet mount microscopy and Nugent score, 84 (85.7%) of 98 samples. The sensitivity and specificity of the methods studied were as follows: 75% (21/28) and 97.1% (68/70) for Nugent score, 96.4% (27/28) and 94.3% (66/70) for wet mount microscopy, 92.8% (26/28) and 85.7% (60/70) for PCR, respectively. CONCLUSIONS: This study demonstrated that wet mount microscopy is a superior method for BV diagnosis. The PCR test under study showed a high sensitivity and can be used for discrimination between normal flora and BV.

RESUMEN

OBJECTIVE: To determine whether von Frey filaments are effective in the standardized assessment of the severity of focal provoked vulvodynia (FPV) syndrome. STUDY DESIGN: The data of 30 women with FPV attending monthly at our vulvovaginal disease clinic, for a collective total of 141 visits over 6 months, were analyzed. At each visit sensitivity tests at the vulvar vestibule were performed at the 5 and 7 o'clock area, totaling 282 measurements. A questionnaire, blinded to the examining physician, and a visual analogue score (VAS) of pain ranging from 1 (no pain) to 10 (maximal pain) was obtained of the discomfort felt when attempting sexual intercourse. RESULTS: The VAS, the investigator assessment of redness, and the 1 to 10 score result of the cotton swab touch test at 5 and 7 o'clock were superior diagnostic tools for assessing the severity of the pain when compared to the use of von Frey filaments. CONCLUSION: Although elegant because of the promise of objective, semiquantitative measurements, von Frey filaments are less suitable devices to assess severity of disease and response to treatment than are cotton swab 1 to 10 pain scores and clinical parameters like subjective pain (VAS) and objective focal redness.
