RESUMEN
The study objective is to examine epidemiological and microbiological aspects of aerobic vaginitis in female patients admitted to University Hospital of Campania "L. Vanvitelli" over five years. The most represented strains were E. coli (n = 153), Citrobacter spp. increasing from 2020, E. faecalis (n = 149), S. haemolitycus (n = 61), and Candida albicans (n = 87). The susceptibility patterns of a selection of gram-negative and gram-positive representative bacterial isolates were examined. Carbapenems, aminoglycosides, and fosfomycin were most effective against gram-negative bacteria, whereas vancomycin, daptomycin, and linezolid exhibited greater efficacy against gram-positive bacteria. None of the E. coli and Citrobacter spp. isolates produced extended-spectrum beta-lactamases, and the S. haemolyticus strains were methicillin-resistant. In gram-positive isolates, gentamicin susceptibility increased in 2020 and 2021 compared to clindamycin; erythromycin showed high resistance rates in 2020. Our findings indicate that integrating proper microbiological cultures into clinical practice could improve the management of aerobic vaginitis. Moreover, they highlight the necessity of establishing a nationwide surveillance guideline to mitigate antimicrobial resistance. Improvement actions in antimicrobial diagnostic stewardship must be considered when seeking the appropriate diagnosis and treatment for aerobic vaginitis.

ABSTRACT: Vaginal discharge is a common presenting complaint in ambulatory care medicine, emergency medicine, primary care, and gynecology, accounting for nearly 10 million office visits annually in the United States. This article discusses management of abnormal vaginal discharge among women of childbearing age and the clinical significance of inhouse diagnostic tools. Provider-performed microscopy is an invaluable clinical skill that allows for immediate diagnosis, treatment, and management of infections and coinfections and should be strongly considered when evaluating a patient.

OBJECTIVE: Nowadays, there has been limited Mendelian randomization (MR) research focusing on the causal relationship between estradiol and vaginitis. Therefore, this study conducted a two-way MR study to clarify the causal effect and related influencing factors between them. METHODS: All genetic datasets were obtained using publicly available summary statistics based on individuals of European ancestry from the IEU GWAS database. MR analysis was performed using MR-Egger, weighted median (WM) and inverse variance weighted (IVW) methods to assess the causal relationship between exposure and outcome and to validate the findings by comprehensively evaluating the effects of pleiotropic effects and outliers. RESULTS: MR analysis revealed no significant causal relationship between estradiol and vaginitis risk. There was a negative correlation between estradiol and age at menarche (IVW, OR: 0.9996, 95% CI: 0.9992-1.0000, P = 0.0295; WM, OR: 0.9995, 95% CI: 0.9993-0.9998, P = 0.0003), and there was a positive correlation between age at menarche and vaginitis (IVW, OR: 1.5108, 95% CI: 1.1474-2.0930, P = 0.0043; MR-Egger, OR: 2.5575, 95% CI: 1.7664-9.6580, P = 0.0013). Estradiol was negatively correlated with age at menopause (IVW, OR: 0.9872, 95% CI: 0.9786-0.9959, P = 0.0041). However, there was no causal relationship between age at menopause and vaginitis (P > 0.05). In addition, HPV E7 Type 16, HPV E7 Type 18, and Lactobacillus had no direct causal effects on estradiol and vaginitis (P > 0.05). Sensitivity analyses revealed no heterogeneity and horizontal pleiotropy. CONCLUSION: When estrogen levels drop, it will lead to a later age of menarche, and a later age of menarche may increase the risk of vaginitis, highlighting that the longer the female reproductive tract receives estrogen stimulation, the stronger the defense ability is formed, and the prevalence of vaginitis is reduced. In conclusion, this study indirectly supports an association between reduced level of estrogen or short time of estrogen stimulation and increased risk of vaginitis.

In April 2020, two cows in Japan, developed reproductive disorders accompanied by vaginitis with purulent discharge within 3 days of artificial insemination (AI) with the same lot of frozen semen. Histophilus somni was isolated from the vaginal swabs of both cows as well as from the same lot of frozen semen used for the AI. This incident marks the first reported case of H. somni infection in cattle through AI. The major outer membrane protein gene sequences and pulsed-field gel electrophoresis profiles of the isolates were identical. Moreover, we investigated the antimicrobial activity of 12 frozen semen straws against an H. somni isolate using a disk diffusion test. These straws were sourced from five AI centers and included the same lot of semen used for the AI. Although the composition of semen diluents from individual AI centers is not publicly available, both the same lot of frozen semen used in the AI and other lots produced by the same manufacturer showed lower antimicrobial activity than semen from other manufacturers. These results strongly suggest that the two vaginitis were caused by AI using H. somni-contaminated frozen semen because of insufficient antimicrobial activity to inhibit bacterial growth. The minimum inhibitory concentrations of the six antimicrobials recommended for addition to frozen semen in isolates were below the recommended concentrations, suggesting that proper addition could have prevented this incident. This highlights the importance of conducting periodical checks on the antibacterial activity of frozen semen to prevent the transmission of pathogens via AI.

Objective: To determine the etiology of cervico-vaginal infections by cytobacteriology and the efficacy of qPCR for the diagnosis of sensitive strains such as Streptococcus agalactiae, Borrelia crocidurae, Chlamydia trachomatis, Neisseria gonorrhoeae and Treponema pallidum. Methodology: This prospective cross-sectional study was performed between January and September 2021 in 346 women who were examined for cervico-vaginal infection at the Hôpital Principal de Dakar (HPD). Cytobacteriological (direct examination, agar culture) and molecular analyses were performed. Results: Vaginal flora imbalances predominated, with a rate of 72.3%. The proportion of type IV vaginal flora was 46.5%. Of the 199 germs isolated, Candida albicans (25.1%), Ureaplasma urealyticum (17.6%), S. agalactiae (7.8%), Gardnerella vaginalis (6.6%) and nonalbicans Candida (5.5%) were the main pathogens responsible for cervico-vaginal infections in patients. Among women tested for mycoplasma, U. urealyticum was identified in 43.3% of patients. Among those tested for C. trachomatis, the proportion of infected women was low (4%). The prevalence of C. albicans was higher in pregnant women (38.3%) than in nonpregnant women (19.2%). S. agalactiae strains showed high resistance to certain beta-lactam antibiotics (pristinamycin 100%, gentamycin 100%, ampicillin 92.5% and cefalotin 85.2%) and to a glycopeptide antibiotic (vancomycin 100%). The Staphylococcus aureus strain had good sensitivity to antibiotics except gentamycin (100%) and kanamycin (100%). The enterobacteria tested were all sensitive to phenicols, carbapenems, cephalosporins and aminoglycosides. However, E. coli showed high resistance to tetracycline. The different methods showed low prevalences of C. trachomatis and N. gonorrhoeae, so comparisons Test RapidChlamydia/qPCR for C. trachomatis and culture/qPCR for N. gonorrhoeae were not possible. For S. agalactiae, on the other hand, qPCR was more advantageous than culture. The χ2 test showed a significant difference (Yates χ2 = 33.77 and p = 1-7) for the diagnosis of S. agalactiae. S. agalactiae qPCR had a sensitivity of 40.7%, a specificity of 94%, and positive and negative predictive values of 36.7% and 94.9% respectively, as well as a kappa = 0.33. Conclusion: The methods applied enabled us to identify the pathogens that cause cervicovaginal infections. The results suggest that qPCR may be an alternative, at least for the diagnosis of S. agalactiae. However, culture remains indispensable for studying antibiotic sensitivity. In order to improve patient care, molecular techniques need to be integrated into the HPD testing toolbox. To broaden the repertoire of pathogens to be diagnosed by qPCR, targeted comparison studies will be needed to increase the probability of encountering infected individuals.

Vaginitis, a prevalent gynecological condition in women, is mainly caused by an imbalance in the vaginal micro-ecology. The two most common types of vaginitis are vaginal bacteriosis and vulvovaginal candidiasis, triggered by the virulent Gardnerella vaginalis and Candida albicans, respectively. In this study, a strain capable of inhibiting G. vaginalis and C. albicans was screened from vaginal secretions and identified as Lactobacillus gasseri based on 16S rRNA sequences. The strain, named L. gasseri VHProbi E09, could inhibit the growth of G. vaginalis and C. albicans under co-culture conditions by 99.07% ± 0.26% and 99.95% ± 0.01%, respectively. In addition, it could significantly inhibit the adhesion of these pathogens to vaginal epithelial cells. The strain further showed the ability to inhibit the enteropathogenic bacteria Escherichia coli and Salmonella enteritidis, to tolerate artificial gastric and intestinal fluids and to adhere to intestinal Caco-2 cells. These results suggest that L. gasseri VHProbi E09 holds promise for clinical trials and animal studies whether administered orally or directly into the vagina. Whole-genome analysis also revealed a genome consisting of 1752 genes for L. gasseri VHProbi E09, with subsequent analyses identifying seven genes related to adhesion and three genes related to bacteriocins. These adhesion- and bacteriocin-related genes provide a theoretical basis for understanding the mechanism of bacterial inhibition of the strain. The research conducted in this study suggests that L. gasseri VHProbi E09 may be considered as a potential probiotic, and further research can delve deeper into its efficacy as an agent which can restore a healthy vaginal ecosystem.

Objective: To determine the optimum biofilm formation ratio of Gardnerella vaginalis (G. vaginalis) in a mixed culture with Escherichia coli (E. coli). Methods: G. vaginalis ATCC14018, E. coli ATCC25922, as well as five strains of G. vaginalis were selected from the vaginal sources of patients whose biofilm forming capacity was determined by the Crystal Violet method. The biofilm forming capacity of E. coli in anaerobic and non-anaerobic environments were compared using the identical assay. The Crystal Violet method was also used to determine the biofilm forming capacity of a co-culture of G. vaginalis and E. coli in different ratios. After Live/Dead staining, biofilm thickness was measured using confocal laser scanning microscopy, and biofilm morphology was observed by scanning electron microscopy. Results: The biofilm forming capacity of E. coli under anaerobic environment was similar to that in a 5% CO2 environment. The biofilm forming capacity of G. vaginalis and E. coli was stronger at 106:105 CFU/mL than at other ratios (P<0.05). Their thicknesses were greater at 106:105 CFU/mL than at the other ratios, with the exception of 106:102 CFU/mL (P<0.05), under laser scanning microscopy. Scanning electron microscopy revealed increased biofilm formation at 106:105 CFU/mL and 106:102 CFU/mL, but no discernible E. coli was observed at 106:102 CFU/mL. Conclusion: G. vaginalis and E. coli showed the greatest biofilm forming capacity at a concentration of 106:105 CFU/mL at 48 hours and could be used to simulate a mixed infection of bacterial vaginosis and aerobic vaginitis in vitro.

The human microbiome contains genetic information that regulates metabolic processes in response to host health and disease. While acidic vaginal pH is maintained in normal conditions, the pH level increases in infectious vaginitis. We propose that this change in the vaginal environment triggers the biosynthesis of anti-vaginitis metabolites. Gene expression levels of Chryseobacterium gleum, a vaginal symbiotic bacterium, were found to be affected by pH changes. The distinctive difference in the metabolic profiles between two C. gleum cultures incubated under acidic and neutral pH conditions was suggested to be an anti-vaginitis molecule, which was identified as phenylacetic acid (PAA) by spectroscopic data analysis. The antimicrobial activity of PAA was evaluated in vitro, showing greater toxicity toward Gardnerella vaginalis and Candida albicans, two major vaginal pathogens, relative to commensal Lactobacillus spp. The activation of myeloperoxidase, prostaglandin E2, and nuclear factor-κB, and the expression of cyclooxygenase-2 were reduced by an intravaginal administration of PAA in the vaginitis mouse model. In addition, PAA displayed the downregulation of mast cell activation. Therefore, PAA was suggested to be a messenger molecule that mediates interactions between the human microbiome and vaginal health.

Aerobic vaginitis (AV) is a distinct clinical entity characterized by inflammation and abnormal vaginal microflora. Often mistaken for bacterial vaginosis, AV remains relatively unknown and underdiagnosed. AV's understanding is evolving, with some experts suggesting it may primarily be an immunological disorder, the prevalence of which has a range of 7-13% in non-pregnant women and 4.1-8.3% during pregnancy. Pregnancy can affect susceptibility to vaginal infections, leading to adverse outcomes for the woman and the newborn. This review summarizes the correlation between AV and adverse pregnancy outcomes, particularly preterm birth, the leading cause of morbidity and mortality among neonates. An improved understanding of AV's impact on pregnancy outcomes can lead to early recognition, proper management, and effective interventions. While some studies support an association between AV and preterm labor, the existing knowledge of this relationship remains limited. The evidence suggests that AV may contribute to adverse pregnancy outcomes, mainly preterm birth, but further research is needed to establish a definitive link. Further studies are needed to investigate the underlying mechanisms and clarify AV's role in premature labor. A comprehensive understanding of AV's impact on pregnancy outcomes is crucial for early recognition, appropriate management, and effective interventions.

Reproductive tract infections (RTIs) are a persistent public health threat worldwide, particularly among women in low-income countries of Africa, including Ethiopia, where drug resistance is also a growing problem. It is crucial to address this problem to ensure women's health and well-being. A cross-sectional study was carried out among a cohort of 398 women of reproductive age who sought medical attention at the Gynecology Department of the Arba Minch General Hospital, southern Ethiopia, from January to June 2020. They were chosen through systematic random sampling, and a pre-tested structured questionnaire was used to collect the data. The collection of vaginal and/or cervical swabs were done to diagnose bacterial vaginosis (BV) and aerobic vaginitis (AV) using Nugent and AV score analyses, respectively. The swabs were subjected to standard microbiological culture techniques to detect the isolates causing AV and vaginal candidiasis (VC). The susceptibility profiles of the causative agents of AV were checked by the Kirby-Bauer disc diffusion technique. Descriptive and inferential statistical analyses were also done. Aerobic vaginitis was the predominantly diagnosed RTI (n = 122, 30.7%), followed by BV (n = 117, 29.4%) and VC (n = 111, 27.9%). The prominent bacteria of AV were Escherichia coli (n = 36, 34.2%) and Klebsiella pneumoniae (n = 30, 28.5%). The overall rate of multidrug-resistant (MDR) bacteria was 65.71% (n = 69). History of abortion (p = 0.01; AOR = 4.0, 95% CI = 2.1, 7.7) and the habit of using vaginal pH-altering contraceptives (p = 0.01; AOR = 4.7, 95% CI = 2.5, 8.8) have the greatest odds of RTI. The high prevalence of RTIs in our study warrants an urgent intervention to minimize the associated morbidities and complications. The overall rate of MDR bacterial isolates necessitates the implementation of an effective surveillance program in the study setting.

PURPOSE OF REVIEW: To examine impact of vaginal dysbiosis (VD), including bacterial vaginosis (BV) and aerobic vaginitis (AV) on reproductive outcomes of in vitro fertilization (IVF) patients. RECENT FINDINGS: BV-bacteria (e.g. Gardnerella ) and AV-bacteria (e.g. Streptococci and Enterococci ) have been identified in the endometrium. However, there is inconclusive evidence whether IVF patients with VD have lower success rates. SUMMARY: The present systematic review and meta-analysis of PubMed/Medline, until December 2023 included 25 studies, involving 6835 IVF patients. Overall VD was defined as an approximation of community state type IV, including BV and AV-type dysbiosis based on either molecular or microscopy methods. Outcomes were live birth rate (LBR), early pregnancy loss (EPL), clinical pregnancy rate (CPR), and biochemical pregnancy rate (BPR).Vaginal dysbiosis prevalence was 19% [1271/6835, 95% confidence interval (CI) 18-20%]. Six studies examined AV-type dysbiosis with a prevalence of 4% (26/628, 95% CI 3-6%). Vaginal dysbiosis correlates with a higher EPL [relative risk (RR)â=â1.49, 95% CI 1.15-1.94] and lower CPR (RRâ=â0.82, 95% CI 0.70-0.95). No statistically significant impact of VD, BV, or AV was found on LBR and BPR.Thus, the association between VD and reproductive outcome remains puzzling as it is difficult to explain how VD impacts CPR and EPL but not LBR and BPR.

Molecular diagnostic testing (eg, polymerase chain reaction [PCR]-based vaginitis testing) is widely used in clinical practice, although vaginitis experts have reservations about its use for vaginitis diagnosis. As with any new technology, cost to the health system is a large concern. Although clinical evaluation of signs and symptoms along with wet mount microscopy is traditionally used for vaginitis diagnosis, it is less accurate compared with molecular diagnostic testing. Here we review the benefits of adopting newer molecular diagnostics into routine gynecologic practice with some guidance from vaginitis experts that favor both traditional and more modern approaches. We argue that instead of trying to resist the oncoming tide of molecular diagnostics, we can embrace them and put them to appropriate use to effect rapid, accurate, and more flexible diagnosis of vaginitis conditions for our patients.

A primigravida in her late 20s presented to the obstetrics and gynaecology department in labour. On per speculum examination, multiple cystic lesions, 1-5 mm in size were observed occupying the anterior, posterior and lateral vaginal walls. Vaginal wet mount was normal and vaginal cultures were negative. Biopsy findings were consistent with emphysematous vaginitis. Vaginitis emphysematosa is a rare, benign self-limiting condition that presents with multiple, air-filled cysts in the vaginal or ectocervical mucosa. This condition is seen in both gravid and non gravid women, usually associated with a Trichomonas or Gardnerella infection.

Objective: This meta-analysis aims to assess the efficacy of combining clotrimazole and metronidazole in the treatment of mixed infectious vaginitis (VA). The goal is to provide clinical guidance for future medication strategies. Methods: We conducted a comprehensive search of the literature database for studies involving the use of clotrimazole combined with metronidazole in the treatment of mixed infectious VA. After rigorous screening, eligible studies were subjected to meta-analysis using RevMan 5.3 software. Outcome measures included cure rates, recurrence rates, and the incidence of adverse reactions. Results: Six randomized controlled trials (RCTs) were included, comprising 160 patients in the test group (treated with clotrimazole combined with metronidazole) and 160 patients in the control group (treated with alternative regimens). All selected studies were of high quality and possessed significant reference value. Meta-analysis results indicated that, in comparison to the control group, the test group exhibited a comparable incidence of adverse reactions (P > .05), higher cure rates, increased treatment satisfaction, and a lower recurrence rate (P < .05). Conclusions: The combination of clotrimazole and metronidazole is an effective treatment option for mixed infectious vaginitis, thus warranting recommendation.

BACKGROUND: Bacterial vaginosis (BV) is a highly prevalent vaginal infection. OBJECTIVES: Primary objectives of this study were to examine treatment patterns among female patients with Medicaid coverage who were diagnosed with incident BV, the frequency of BV-associated complications, and health care resource utilization (HCRU) and associated costs of incident BV and its recurrence. Secondary objectives were to identify predictors of total all-cause health care costs and number of treatment courses. METHODS: Female patients aged 12-49 years with an incident vaginitis diagnosis and ≥1 pharmacy claim for a BV medication were selected from the Merative MarketScan Medicaid database (2017-2020). Additional treatment courses were evaluated during a ≥12-month follow-up period, in which new cases of BV-associated complications and HCRU and the associated costs were also measured. Generalized linear models were used to identify baseline predictors of total all-cause health care costs and number of treatment courses. RESULTS: An incident vaginitis diagnosis and ≥1 BV medication claim were present in 114 313 patients (mean age: 28.4 years; 48.6% black). During the follow-up, 56.6% had 1 treatment course, 24.9% had 2, 10.2% had 3, and 8.3% had ≥4; 43.4% had BV recurrence. Oral metronidazole (88.5%) was the most frequently prescribed medication. Nearly 1 in 5 had a new occurrence of a BV-associated complication; most (76.6%) were sexually transmitted infections (STIs). Total all-cause and BV-related costs averaged $5794 and $300, respectively, per patient; both increased among those with more treatment courses. Older age, pregnancy, comorbidity, any STIs, postprocedural gynecological infection (PGI), and infertility were predictive of higher total all-cause health care costs, while race/ethnicity other than white was predictive of lower costs. Older age, black race, any STIs, pelvic inflammatory disease, and PGI were predictive of >1 treatment courses. CONCLUSION AND RELEVANCE: The high recurrence of BV represents an unmet need in women's health care and better treatments are necessary.

B-cell depleting therapies are effective in multiple sclerosis (MS) and are widely used (Hauser et al., 2017). Inflammatory vaginitis (IV), characterized by unexplained vaginal symptoms including mucopurulent discharge, pain, irritation, and dyspareunia, has been reported in one MS patient on ocrelizumab (Filikci and Jensen, 2022), and to be present in 3.5 % of women on rituximab for autoimmune diseases (Yockey et al., 2021). We report here four cases of IV in B cell depleted women with MS. B-cell reconstitution was temporally associated with improvement of IV symptoms. Further investigation and vigilance for this potential treatment emergent adverse event affecting sexual and reproductive health of women with MS is needed.

Aerobic vaginitis (AV) is a recently defined vaginal recurring infection, which is treated with antibiotics. However, excessive and prolonged use of antibiotics disrupts healthy vaginal microflora and leads to the emergence of antibiotic resistance among pathogens. This situation has directed researchers to explore alternative antimicrobials. The current study describes in vitro and in vivo antimicrobial efficacy and pharmaceutical interactions between plant essential oils (EOs) and five lactic acid bacteria (LABs), isolated from the healthy vagina, against E. faecalis, one of the major etiological agents of AV. In vitro experiments confirm good antimicrobial activity of both plant EOs and cell free supernatant (CFS) from LABs. Based on high antimicrobial efficacy, Moringa essential oil (MO) was selected to determine its nature of interaction with CFS of five LAB strains. Synergism was recorded between MO and CFS of L. reuteri (MT180537). To validate in vitro findings, prophylactic responses of individual and synergistic application of MO and L. reuteri (MT180537) were evaluated in an E. faecalis (MW051601) induced AV murine model. The prophylactic efficacy was evidenced by a reduction in intensity of clinical symptoms, E. faecalis (MW051601) count per vaginal tissue along with a reduction in AV associated changes in histological markers of infection in animals receiving Moringa essential oil and L. reuteri (MT180537) alone or in combination. However, significant synergism between Moringa essential oil and L. reuteri (MT180537) could not be observed. Our data confirms the importance of in vivo experiments in deducing pharmacological interactions.
Vaginite aeróbica (VA) é uma infecção vaginal recorrente definida recentemente, que é tratada com antibióticos. No entanto, o uso excessivo e prolongado de antibióticos perturba a microflora vaginal saudável e leva ao surgimento de resistência aos antibióticos entre os patógenos. Esta situação levou os pesquisadores a explorar antimicrobianos alternativos. O presente estudo descreve a eficácia antimicrobiana in vitro e in vivo e as interações farmacêuticas entre óleos essenciais vegetais (OE) e cinco bactérias lácticas (BAL), isoladas de vagina sã, contra E. faecalis, um dos principais agentes etiológicos da AV. Os experimentos in vitro confirmam a boa atividade antimicrobiana de ambos os EOs de plantas e sobrenadante livre de células (CFS) de LABs. Com base na alta eficácia antimicrobiana, o óleo essencial de Moringa (MO) foi selecionado para determinar sua natureza de interação com o sobrenadante livre de células (CFS) de cinco cepas de LAB. Sinergismo foi registrado entre MO e CFS de L. reuteri (MT180537). Para validar os resultados in vitro, as respostas profiláticas da aplicação individual e sinérgica de MO e L. reuteri (MT180537) foram avaliadas em um modelo murino AV induzido por E. faecalis (MW051601). A eficácia profilática foi evidenciada por uma redução na intensidade dos sintomas clínicos, contagem de E. faecalis (MW051601) por tecido vaginal, juntamente com uma redução nas alterações associadas a AV nos marcadores histológicos de infecção em animais que receberam óleo essencial de Moringa e L. reuteri (MT180537) sozinho ou em combinação. No entanto, não foi possível observar sinergismo significativo entre o óleo essencial de Moringa e L. reuteri (MT180537). Nossos dados confirmam a importância dos experimentos in vivo na dedução de interações farmacológicas.

OBJECTIVE: Aim: To determine prevalence of Aerobic Vaginitis (AV) after gynecologic surgery, risk factors and antimicrobial resistance of responsible pathogens, and adverse pregnancy outcomes in Ukraine. PATIENTS AND METHODS: Materials and Methods: Multicenter retrospective cohort study was conducted from January 2020 to December 2022 in fifteen medical clinics from eight regions of Ukraine. Smears were analyzed using Donders' classification method and Dong's modified AV diagnosis for Gram stains. Definitions of HAIs were adapted from the CDC/NHSN. Antibiotic susceptibility testing of bacteria was determined by Kirby-Bauer disc diffusion test according to the protocol of the EUCAST. RESULTS: Results: Prevalence of AV among women's undergoing gynecologic surgery in Ukraine was 68.7%. Of the total AV cases, 70.3% were in non-pregnant and 29,7% in pregnant women. The most common pathogen of AV was Escherichia coli, followed by Enterococcus faecalis, Streptococcus agalactiae, Staphylococcus aureus, Enterococcus faecium, Klebsiella pneumoniae, and Pseudomonas aeruginosa. Among the S. aureus strains, 11,6% of MRSA (Methicillin resistant S.aureus) were isolated whereas none of the CoNS were cefoxitin resistant. History of vaginal infection, history of post-operative infection and antibiotic use acted as an important risk factor of AV incidence rate. The presence of AV worsened pregnancy outcomes, by increasing the incidence of preterm birth, the premature rupture of membranes, miscarriage, neonatal jaundice, and neonatal infection. CONCLUSION: Conclusions: Aerobic Vaginitis after gynecological surgeries in Ukraine is a common medical problem in women that is associated with significant morbidity, adverse pregnancy outcome, and hence frequent medical visits.

El objetivo es conocer el abordaje diagnóstico y terapéutico de la vaginosis citolítica. Para ello se hizo una búsqueda sistemática de la literatura médica mediante las bases de datos: PubMed, Central, etc. Se limitó a ensayos clínicos aleatorizados, metaanálisis y revisiones bibliográficas, con disponibilidad del texto completo para evaluarlos en su totalidad e incluirlos en la revisión; publicados entre 1980 y 2021. Se incluyeron 27 publicaciones. La vaginosis citolítica es un trastorno infradiagnosticado. En mujeres con síntomas y signos de candidiasis vulvovaginal, que no responden a la terapia, se debe considerar la probabilidad de estar en presencia de una vaginosis citolítica. El tratamiento obliga a elevar el pH vaginal a valores básicos y a disminuir el número excesivo de Lactobacillus, resultando de utilidad las duchas vaginales con bicarbonato de sodio y/o un tratamiento con antibióticos derivados de la penicilina junto a un inhibidor de ß-lactamasas o doxiciclina en las pacientes alérgicas a la penicilina. Finalmente, se concluye que la vaginosis citolítica es una afección común, frecuentemente se diagnostica de forma errónea porque se confunde con la candidiasis vulvovaginal; se caracteriza por producir un cuadro clínico similar. El tratamiento se enfoca en disminuir el número de Lactobacillus y la elevación del pH vaginal.
The objective is to know the diagnostic and therapeutic approach of cytolytic vaginosis. A systematic search of the medical literature was carried out using the following databases: Medline via PubMed, Central, and Cochrane Database of Systematic Reviews, among others. The search was limited to randomized clinical trials, meta-analyses, and literature reviews that had the full text available for full evaluation and inclusion in the review; published between 1980 and 2021. Twenty-seven publications were included. Cytolytic vaginosis is a frequently underdiagnosed disorder, which mimics Candida vaginitis. In women with symptoms and signs of vulvovaginal candidiasis who do not respond to antifungal therapy, the possibility of cytolytic vaginosis should be considered. The treatment of this condition requires raising the vaginal pH to basic values and reducing the excessive number of Lactobacillus, resulting in useful vaginal douches with sodium bicarbonate and/or treatment with antibiotics derived from penicillin together with a ß-lactamases inhibitor or doxycycline in patients allergic to penicillin. Finally, we conclude that cytolytic vaginosis is a common condition, frequently misdiagnosed because it is confused with vulvovaginal candidiasis, since it is characterized by producing a similar clinical picture. Treatment focuses on reducing the number of Lactobacillus and raising vaginal pH.

Malformações müllerianas correspondem a variações anatômicas do trato repro- dutor feminino. Comumente assintomáticas, o diagnóstico e a verdadeira incidên- cia são difíceis de determinar. A síndrome de Herlyn-Werner-Wunderlich, clas- sicamente descrita pela tríade útero didelfo, hemivagina cega e agenesia renal ipsilateral também pode ter variações diferentes. Em virtude da mesma origem embrionária dos tratos genital e urinário, anomalias renais devem ser investigadas nesses casos, sendo a mais comum a agenesia renal. Este artigo relata o caso de uma paciente de 18 anos, do sexo feminino, com história de piocolpo por cinco anos. Em propedêutica complementar, foi identificado útero com septação com- pleta associado a hemissepto de terço superior de vagina, formação de piocolpo e agenesia renal à direita. Apesar de não ser a definição clássica, o quadro está incluído nos casos de síndrome de Herlyn-Werner-Wunderlich.
Mullerian malformations correspond to anatomical variations of the female repro- ductive tract. Commonly asymptomatic, the diagnosis and true incidence are difficult to determine. The Herlyn-Werner-Wunderlich syndrome, classically described by the triad: uterus didelphus, blind hemivagina and ipsilateral renal agenesis, can also have different variations. Due to the same embryonic origin of the genital and urinary tracts, renal anomalies must be investigated in these cases, the most common being renal agenesis. This article reports the case of an 18-year-old female patient with a 5-year history of pyocolpus. In complementary exams, a uterus with complete septa- tion was identified, associated with a hemiseptum in the upper third of the vagina, formation of pyocolpus and renal agenesis on the right side. Despite not being the classic definition, it is included in the cases of Herlyn-Werner-Wunderlich syndrome.
