Pharmacological treatment for obstructive sleep apnea: A systematic review and meta-analysis

Abstract Objective Summarize the evidence on drug therapies for obstructive sleep apnea. Methods The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed. PubMed, Embase, Scopus, Web of Science, SciELO, LILACS, Scopus, Cochrane Central Register of Controlled Trials, and ClinicalTrials.gov were searched on February 17th, 2023. A search strategy retrieved randomized clinical trials comparing the Apnea-Hypopnea Index (AHI) in pharmacotherapies. Studies were selected and data was extracted by two authors independently. The risk of bias was assessed using the Cochrane Risk of Bias tool. RevMan 5.4. was used for data synthesis. Results 4930 articles were obtained, 68 met inclusion criteria, and 29 studies (involving 11 drugs) were combined in a meta-analysis. Atomoxetine plus oxybutynin vs placebo in AHI mean difference of -7.71 (-10.59, -4.83) [Fixed, 95 % CI, I2 = 50 %, overall effect: Z = 5.25, p < 0.001]. Donepezil vs placebo in AHI mean difference of -8.56 (-15.78, -1.33) [Fixed, 95 % CI, I2 = 21 %, overall effect: Z = 2.32, p = 0.02]. Sodium oxybate vs placebo in AHI mean difference of -5.50 (-9.28, -1.73) [Fixed, 95 % CI, I2 = 32 %, overall effect: Z = 2.86, p = 0.004]. Trazodone vs placebo in AHI mean difference of -12.75 (-21.30, -4.19) [Fixed, 95 % CI, I2 = 0 %, overall effect: Z = 2.92, p = 0.003]. Conclusion The combination of noradrenergic and antimuscarinic drugs shows promising results. Identifying endotypes may be the key to future drug therapies for obstructive sleep apnea. Moreover, studies with longer follow-up assessing the safety and sustained effects of these treatments are needed. PROSPERO registration number CRD42022362639.

Efficacy, Safety, and Acceptability of Misoprostol in the Treatment of Incomplete Miscarriage: A Systematic Review and Meta-analysis / Eficácia, segurança e aceitabilidade do misoprostol no tratamento do aborto incompleto: Uma revisão sistemática e metanálise

Abstract Objective To assess the efficacy, safety, and acceptability of misoprostol in the treatment of incomplete miscarriage. Data sources The PubMed, Scopus, Embase, Web of Science, Cochrane Library, and Clinical Trials databases (clinicaltrials.gov) were searched for the relevant articles, and search strategies were developed using a combination of thematic Medical Subject Headings terms and text words. The last search was conducted on July 4, 2022. No language restrictions were applied. Selection of studies Randomized clinical trials with patients of gestational age up to 6/7 weeks with a diagnosis of incomplete abortion and who were managed with at least 1 of the 3 types of treatment studied were included. A total of 8,087 studies were screened. Data collection Data were synthesized using the statistical package Review Manager V.5.1 (The Cochrane Collaboration, Oxford, United Kingdom). For dichotomous outcomes, the odds ratio (OR) and 95% confidence interval (CI) were derived for each study. Heterogeneity between the trial results was evaluated using the standard test, I2 statistic. Data synthesis When comparing misoprostol with medical vacuum aspiration (MVA), the rate of complete abortion was higher in the MVA group (OR = 0.16; 95%CI = 0.07-0.36). Hemorrhage or heavy bleeding was more common in the misoprostol group (OR = 3.00; 95%CI = 1.96-4.59), but pain after treatment was more common in patients treated with MVA (OR = 0.65; 95%CI = 0.52-0.80). No statistically significant differences were observed in the general acceptability of the treatments. Conclusion Misoprostol has been determined as a safe option with good acceptance by patients.

A heterogeneidade entre os resultados do ensaio foi avaliada usando o teste padrão, estatística I2. Síntese dos dados Ao comparar misoprostol com aspiração a vácuo médico (MVA, na sigla em inglês), a taxa de aborto completo foi maior no grupo MVA (OR = 0,16; IC95% = 0,07-0,36). Hemorragia ou sangramento intenso foi mais comum no grupo do misoprostol (OR = 3,00; 95%CI = 1,96-4,59), mas a dor após o tratamento foi mais comum em pacientes tratados com MVA (OR = 0,65; 95%CI = 0,52-0,80). Não foram observadas diferenças estatisticamente significativas na aceitabilidade geral dos tratamentos. Conclusão O misoprostol tem se mostrado uma opção segura e com boa aceitação pelos pacientes.

Maternal near miss: before and during the coronavirus disease 2019 pandemic

SUMMARY OBJECTIVE: The aim of this study was to evaluate and compare Maternal Near Miss prevalence and outcomes before and during the coronavirus disease 2019 pandemic. METHODS: This retrospective study was carried out in a university maternity hospital of high complexity. The population was divided into two groups: G1, 1 year before the coronavirus disease 2019 pandemic period (August 2018-July 2019) and G2, 1 year during the pandemic period (August 2020-July 2021). All pregnant/postpartum women hospitalized up to 42 days after the end of pregnancy/childbirth were included, and pregnant women who were admitted with coronavirus disease 2019/flu symptoms were excluded. The association of variables with "Maternal Near Miss" was estimated using logistic regression. RESULTS: A total of 568 women from G1 and 349 women from G2 fulfilled the Maternal Near Miss criteria. The prevalence of Maternal Near Miss in pre-pandemic was 144.1/1,000 live births and during the pandemic was 78.5/1,000 live births. In the analysis adjusted for G1, the factors of days of hospitalization (PR: 1.02, CI: 1.0-1.0, p<0.05), pre-eclampsia (PR: 0.41, CI: 1.4-2.2, p<0.05), and sepsis/severe systemic infection (PR: 1.79, CI: 0.3-0.4, p<0.05) were crucial for women with the Maternal Near Miss condition to have a greater chance of being admitted to the intensive care unit. In G2, low education (PR: 0.45, CI: 0.2-0.9, p<0.05), eclampsia (PR: 5.28, CI: 3.6-7.6, p<0.05), and use of blood products (PR: 6.48, CI: 4.7-8.8, p<0.05) increased the risk of admission to the intensive care unit. CONCLUSION: During the pandemic, there was a lower prevalence of Maternal Near Miss in high-risk pregnancies, fewer hospitalizations, and more deaths compared to the non-pandemic period.

Maternal-fetal outcomes of women with hypertensive disorders of pregnancy

SUMMARY OBJECTIVE: The objective of this study was to determine adverse maternal and perinatal outcomes in pregnant women with hypertensive disorders of pregnancy. METHODS: An analytical cross-sectional study was conducted on women admitted with hypertensive disorders of pregnancies to a university maternity hospital from August 2020 to August 2022. Data were collected using a pretested structured questionnaire. Variables associated with adverse maternal and perinatal outcomes were compared using multivariable binomial regression. RESULTS: Of 501 women with pregnancies, 2, 35, 14, and 49% had eclampsia, preeclampsia, chronic hypertension, and gestational hypertension, respectively. Women with preeclampsia/eclampsia had significantly higher risks of cesarean section (79.4 vs. 65%; adjusted RR, 2,139; 95%CI, 1,386-3,302; p=0.001) and preterm delivery at <34 weeks' gestation (20.5 vs. 6%; adjusted RR, 2.5; 95%CI, 1.19-5.25; p=0.01) than those of women with chronic/gestational hypertension. Risks of prolonged maternal hospitalization (43.9 vs. 27.1%), neonatal intensive care unit admission (30.7 vs. 19.8%), and perinatal mortality (23.5 vs. 11.2%) were higher among women with preeclampsia/eclampsia. CONCLUSIONS: Women with preeclampsia/eclampsia had a higher risk of adverse maternal and neonatal outcomes than those with chronic or gestational hypertension. This major maternity care center requires strategies for preventing and managing preeclampsia/eclampsia to improve pregnancy outcomes.

Efficacy of Hormonal and Nonhormonal Approaches to Vaginal Atrophy and Sexual Dysfunctions in Postmenopausal Women: A Systematic Review / Eficácia das abordagens hormonais e não hormonais para atrofia vaginal e disfunções sexuais em mulheres na pós-menopausa: Uma revisão sistemática

Abstract Objective To evaluate the efficacy of the hormonal and nonhormonal approaches to symptoms of sexual dysfunction and vaginal atrophy in postmenopausal women. Data Sources We conducted a search on the PubMed, Embase, Scopus, Web of Science, SciELO, the Cochrane Central Register of Controlled Trials (CENTRAL), and Cumulative Index to Nursing and Allied Health Literature (CINAHL) databases, as well as on clinical trial databases. We analyzed studies published between 1996 and May 30, 2020. No language restrictions were applied. Selection of Studies We selected randomized clinical trials that evaluated the treatment of sexual dysfunction in postmenopausal women. Data Collection Three authors (ACAS, APFC, and JL) reviewed each article based on its title and abstract. Relevant data were subsequently taken from the full-text article. Any discrepancies during the review were resolved by consensus between all the listed authors. Data Synthesis A total of 55 studies were included in the systematic review. The approaches tested to treat sexual dysfunction were as follows: lubricants and moisturizers (18 studies); phytoestrogens (14 studies); dehydroepiandrosterone (DHEA; 8 studies); ospemifene (5 studies); vaginal testosterone (4 studies); pelvic floor muscle exercises (2 studies); oxytocin (2 studies); vaginal CO2 laser (2 studies); lidocaine (1 study); and vitamin E vaginal suppository (1 study). Conclusion We identified literature that lacks coherence in terms of the proposed treatments and selected outcome measures. Despite the great diversity in treatment modalities and outcome measures, the present systematic review can shed light on potential targets for the treatment, which is deemed necessary for sexual dysfunction, assuming that most randomized trials were evaluated with a low risk of bias according to the Cochrane Collaboration risk of bias tool. The present review is registered with the International Prospective Register of Systematic Reviews (PROSPERO; CRD42018100488).

Comparative effects of fractional radiofrequency and microneedling on the genitalia of postmenopausal women: Histological and clinical changes

Abstract Objectives: The authors aimed to evaluate clinical and histological changes induced by Fractional Radiofrequency (FRF) and microneedling in vulvar tissue. Methods: Thirty postmenopausal women were randomly divided into G1 (FRF) and G2 (microneedling) groups. Sub-ablative FRF was executed using disposable fractionated electrodes with an intensity of 8 mJ. Microneedling was performed using a derma roller system. The authors evaluated before and after treatment using the Vaginal Laxity Questionnaire (VLQ), EuroQol Five-Dimensional (EQ-5D) questionnaire, and the Blatt and Kupperman Menopausal Index (BKMI). Additionally, the authors performed biopsies of the labia majora for histological analysis pre- and post-treatment. Data were expressed as mean (± standard deviation). A paired t-test was used for intra-group comparison (pre- and post-treatment), with an independent t-test used to compare intergroup data (both pre- and post-treatment). Results: In the G1 group, the VLQ values showed differences compared to the pre-treatment values with the data obtained 60 days after the beginning of the sessions (p = 0.01). Similarly, the data changes of the G2 group proved to be significant (p = 0.001) across the same time interval. In comparing the groups, VLQ values were not different (p > 0.05). Regarding histological analysis, FRF demonstrated improvement concerning the number of fibroblasts, blood vessels, and fatty degeneration (p < 0.05) compared to the control. Additionally, FRF and microneedling samples showed higher type III collagen and vimentin expression in the immunohistochemical analysis (p < 0.05). Conclusions: The therapies were found to be effective in treating the flaccidity of the female external genitalia. Additionally, histological changes were observed after interventions suggesting collagen remodeling.

Histomorphometric analysis in HPV-induced cervical lesions

SUMMARY Introduction: squamous intraepithelial lesions (SIL) of the cervix involve dysplastic change, or abnormal cell maturation and their progression can result in cervical carcinoma. Some studies have reported the importance of the immune system in the process of tumor progression. Therefore, it is important to characterize the inflammatory infiltration as a possible marker of prognosis. Aim: to analyze density of the inflammatory infiltrate in different degrees of SIL and in cervical cancer to under-stand local and systemic changes in the interactions between HPV associated cervical lesions and the immune system. Methods: one hundred and eight (108) cervical biopsy specimens were obtained from patients treated at the tertiary hospital and were stratified into four groups: Low-grade squamous intraepithelial lesion (LSIL), High-grade squamous intraepithelial lesion (HSIL), cervical cancer (CC) and negative for intraepithelial lesion and malignancy (NILM). Histomorphometric analysis was performed from the identification and quantification of inflammatory cells in ten (10) fields per sample in images captured by a digital system and analyzed using the software Leica Qwin Pro V 3.5.1, Leica Microsystems Ltd. Differences between groups were evaluated by Anova followed by Tukey test. Tests yielding p values < 0.05 were considered significant. Results: we found a significant increase in the average number of lymphocytes (cells/mm2 and cells/field) in samples of CC in relation to the other groups. No statistical difference was observed in relation to neutrophils, plasma cells and eosinophils. Conclusion: cervical cancer specimens had significantly more lymphocytes than NILM, or LSIL and HSIL, suggesting that this cell type plays a central role in cellular immunity against cervical carcinoma.

Introducción: las lesiones escamosas intraepiteliales (SIL) del cuello uterino implican cambios displásicos o maduración celular anormal y su progresión puede resultar en carcinoma cervical. Algunos estudios han informado de la importancia del sistema inmunológico en el proceso de progresión tumoral. Por tanto, es importante caracterizar la infiltración inflamatoria como un posible marcador de pronóstico. Objetivo: analizar la densidad del infiltrado inflamatorio en diferentes grados de SIL y en cáncer de cuello uterino para comprender los cambios locales y sistêmicos en las interacciones entre las lesiones cervicales asociadas al VPH y el sistema inmunológico. Métodos: se obtuvieron ciento ocho (108) muestras de biopsia cervical de pacientes tratados en el hospital terciario y se estratificaron en cuatro grupos: Lesión intraepitelial escamosa de bajo grado (LSIL), Lesión intraepitelial escamosa de alto grado (HSIL), cáncer de cuello uterino (CC) y negativo para lesiones intraepiteliales y malignidad (NILM). El análisis histomorfométrico se realizó a partir de la identificación y cuantificación de células inflamatorias en diez (10) campos por muestra en imágenes capturadas por un sistema digital y analizadas utilizando el software Leica Qwin Pro-V 3.5.1, Leica Microsystems Ltd. Anova seguido de la prueba de Tukey. Las pruebas que arrojaron valores de p <0,05 se consideraron significativas. Resultados: encontramos un aumento significativo en el número medio de linfocitos (células/mm2 y células/campo) en muestras de CC en relación con los otros grupos. No se observó diferencia estadística en relación con neutrófilos, células plasmáticas y eosinófilos. Conclusión: las muestras de cáncer de cuello uterino tenían significativamente más linfocitos que NILM o LSIL y HSIL, lo que sugiere que este tipo de células juega un papel central en la inmunidad celular contra el carcinoma de cuello uterino.

Conclusão: as amostras de câncer cervical tinham significativamente mais linfócitos do que NILM, ou LSIL e HSIL, sugerindo que este tipo de célula desempenha um papel central na imunidade celular contra o carcinoma cervical.

Pelvic floor muscle training program for women in the puerperal period: clinical progress after intervention

SUMMARY OBJECTIVE: To evaluate the sexual function of women in the puerperal period after a postpartum pelvic floor musculature training program. We also sought to evaluate correlations between sexual dysfunction in the women and their delivery type and compare the frequency of sexual dysfunction and the quality of resumed sexual function following vaginal and cesarean deliveries. METHODS: This clinical study included an intervention, carried out between July and December 2019, in which data were collected about 28 rooming-in women at a Maternity School. Data were divided into vaginal delivery and cesarean delivery. Sexual function was evaluated by the Female Sexual Function Index and the International Consultation on Incontinence Questionnaire-Short Form to assess the Incontinence Urinary and qualifies urinary loss. The intervention consisted of a muscle training exercise program. ANOVA tests were used to establish differences between groups. RESULTS: There was an improvement in all outcomes, but there was no time versus group interaction. Improvement in sexual function was observed (p<0.001), the impact of urinary incontinence on quality of life (p<0.001), and pressure of the muscles of pelvic floor muscles (p<0.001) over time. There was no time versus group interaction for sexual function (p=0.87), the impact of urinary incontinence on quality of life (p=0.88), and pressure of the pelvic floor muscles (p=0.66). CONCLUSIONS: Pelvic floor muscle exercise programs seem to be a very promising strategy concerning improving sexual activity among puerperal patients.

Guillain-Barré syndrome associated with SARS-CoV-2 infection: a scoping review

SUMMARY BACKGROUND: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections can affect the nervous system, triggering problems such as the Guillain-Barre Syndrome (GBS), an association that can bring complications to the patient. OBJECTIVE: This scoping review aimed to clarify the clinical features and analyze patients with GBS associated with SARS-CoV-2 infection, looking at morbidity, mortality, and neurological outcomes. SEARCH STRATEGY: The search was conducted through Medline, Web of Science, Embase, CINAHAL, Latin-American and Caribbean Literature in Health Sciences (LILACS), clinicaltrials.gov, SCOPUS, and the Cochrane Central Register of Controlled Trials. SELECTION CRITERIA: Observational studies, published after 2019, describe patients with GBS associated with SARS-CoV-2 infection. There were no language restrictions while selecting the studies. DATA COLLECTION AND ANALYSIS: Three authors, Kleyton Santos de Medeiros, Luíza Thomé de Araújo Macêdo, and Wederson Farias de Souza, independently screened the search results using titles and abstracts. Duplicate studies were excluded. The same authors then went through the entire text to determine whether the studies met the inclusion criteria. Discrepancies were resolved by other reviewers, Ana Paula Ferreira Costa, Ayane Cristine Sarmento, and Ana Katherine Gonçalves. Finally, the selection of the studies was summarized in a PRISMA flow diagram. MAIN RESULTS: Main manifestations were fever, coughing, dyspnea, sore throat, ageusia, anosmia, and respiratory failure, in addition to paresthesia of the upper and lower limbs, tetraparesis, facial diplegia, areflexia, asthenia, mastoid pain, acute ataxia, fatigue, numbness, swallowing disorder, and moderate low back pain. CONCLUSION: Coronavirus disease 2019 (COVID-19) can trigger the GBS, despite the few studies on this topic. Patients had clinical manifestations of COVID-19 infection and neurological manifestations characterizing GBS.

Potential impact of the COVID-19 in HIV-infected individuals: a systematic review Impact of the COVID-19 in HIV-Infected Individuals

SUMMARY BACKGROUND: Although much has been studied about the SARS-Cov-2 virus, its effects, and the effectiveness of possible treatments, little is known about its interaction with other infectious diseases. OBJECTIVE: The aim is to study its clinical features and morbidity, and mortality outcomes of COVID-19 patients with HIV/AIDS coinfection. DATA SOURCES: MEDLINE, Web of Science, Embase, CINAHL, LILACS, Scopus, ClinicalTrials.gov, and Cochrane. STUDY ELIGIBILITY CRITERIA: Atudies in any language, published after 2019, were describing COVID-19 patients with HIV/AIDS. STUDY APPRAISAL: JBI Levels of Evidence, Joanna Briggs Institute. SYNTHESIS METHODS: As shown in the PRISMA flow diagram, two authors separately screened the search results from the obtained titles and abstracts. RESULTS: Chest CT was observed in patients with pneumonia by SARS-CoV-2 with findings of multiple ground-glass opacities (GGO) in the lungs, there is a need for supplemental oxygenation. One patient developed encephalopathy and complicated tonic-clonic seizures; four patients were transplanted (two, liver; two, kidneys), one patient developed severe SARS-CoV-2 pneumonia and 30 patients died (mortality rate, 11%). CONCLUSION: HIV did not show any relevance directly with the occurrence of COVID-19. Some studies suggest that HIV-1 infection through induction levels of IFN-I, may to some extent, stop the apparent SARS-CoV-2 infection, thus leading to undetectable RNA. Moreover, some authors suggest retroviral therapy routinely used to control HIV infection could be used to prevent COVID-19 infection.

The real impact of the coronavirus disease 2019 (covid-19) on the pregnancy outcome / O impacto real da doença do coronavirus 2019 (covid-19) no desfecho da gestação

Abstract The COVID-19 outbreak is increasing around the world in the number of cases, deaths, and affected countries. Currently, the knowledge regarding the clinical impact of COVID-19 on maternal, fetal, and placental aspects of pregnancy is minimal. Although the elderly and men were the most affected population, in previous situations, such as the 2009 H1N1 influenza pandemic and the Ebola epidemic, pregnant women were more likely to develop complications than nonpregnant women. There are unanswered questions specific to pregnant women, such as whether pregnant women are more severely affected and whether intrauterine transmission occurs. Additional information is needed to inform key decisions, such as whether pregnant health care workers should receive special consideration, whether to separate infected mothers and their new borns, and whether it is safe for infected women to breastfeed.

Resumo A COVID-19 está se disseminando em todo o mundo, expandindo o número de casos, mortes e países afetados. Atualmente, o conhecimento sobre o impacto da COVID-19 nos desfechos materno, fetal e placentário da gravidez é mínimo. A despeito de serem os homens e idosos a população mais afetada em situações anteriores, como a pandemia de influenza H1N1 de 2009 e a epidemia de Ebola, as gestantes foram mais propensas a desenvolver complicações do que as mulheres não grávidas. Em relação à gravidez, existem questões específicas a serem respondidas, tais como se as mulheres grávidas são mais gravemente afetadas e se ocorre transmissão intrauterina. São necessárias informações adicionais para embasar a tomada de decisões, tais como; se as profissionais de saúde grávidas devem receber atenção especial, se é necessário separar as mães infectadas dos seus recém-nascidos e se é seguro que as puérperas infectadas amamentem.

What influence does vaginal microbiota have on human papillomavirus nfection? / Que influência a microbiota vaginal tem sobre a infecção por Papilomavírus humano?

Introduction: The human body is colonized by trillions of microbial cells, called the microbiota. The microbiome is defined as microbial cells and their genomes. Vaginal microbiota, especially lactic acid bacteria (mainly Lactobacillus sp.), seem to play a critical role in the prevention of various urogenital diseases such as bacterial vaginosis, fungal infections, sexually transmitted diseases, urinary tract infections, and human papillomaviridae (HPV) infections. Changes in the vaginal microbiome contribute to the development of precancerous cervical lesions. Objective: To evaluate studies associating the vaginal microbiota with HPV, including the risk and persistence of infection and evolution to squamous intraepithelial lesions of the cervix. Methods: A systematic review was conducted based on articles published between September 2011 and September 2019, using the following keyword combinations: "HPV [All Fields] AND "microbiota" [MeSH Terms] OR "microbiota" [All Fields] OR "microbiome" [All Fields])." The keyword search was performed in the MEDLINE, Latin American, and Caribbean Literature in Health Sciences (Lilacs), Cochrane Library, Highwire Stanford, and Embase databases. Results: In total, 239 original articles published between 2011 and 2019 were found in the researched databases on microbiome/microbiota and HPV. After exclusion, only six articles remained. Conclusion: There is a relationship between HPV and the cervicovaginal microbiota, but the mechanism of this influence cannot be specified.

Introdução: O corpo humano é colonizado por trilhões de células microbianas, denominadas microbiota. Microbioma é definida como células microbianas e seus genomas. A microbiota vaginal, especialmente as bactérias produtoras de ácido lático (principalmente Lactobacillus sp.), parece desempenhar um papel crítico na prevenção de várias doenças urogenitais, como a vaginose bacteriana, infecções fúngicas, doenças sexualmente transmissíveis, infecções do trato urinário e infecção pelo Papilomavírus humano (HPV). As alterações no microbioma vaginal parecem contribuir para o desenvolvimento de lesões cervicais pré-cancerosas. Objetivo: Avaliar estudos que associem a microbiota vaginal ao risco de infecção por HPV, sua persistência e evolução para lesões escamosas intraepiteliais do colo do útero. Métodos: Esta é uma revisão sistemática desenvolvida com base em artigos publicados entre setembro de 2011 e setembro de 2019, usando as seguintes combinações de palavras-chave: "HPV" [Todos os Campos] AND ("microbiota" [Termos MeSH] OU "microbiota" [Todos os Campos] OU "microbioma" [All Fields]) nas bases de dados MEDLINE, Latin American and Caribean Health Sciences Literature (Lilacs), Cochrane Library, Highwire Stanford e Embase. Resultados: Entre 2011 e 2019, foram encontrados 239 artigos originais nas bases de dados pesquisadas sobre microbioma/microbiota e HPV. Desse total, após o uso dos critérios de exclusão, restaram apenas seis artigos. Conclusão: Existe uma relação entre o HPV e a microbiota cervicovaginal, mas não foi possível especificar qual mecanismo está envolvido.

Impact of microablative fractional radiofrequency on the vaginal health, microbiota, and cellularity of postmenopausal women

OBJECTIVES: We aimed to evaluate the effectiveness of microablative fractional radiofrequency (MAFRF) in the non-hormonal treatment of genitourinary syndrome of menopause. METHODS: We examined the cases of 55 postmenopausal women before and after treatment with regard to their vaginal health index (VHI), vaginal microbiota, vaginal pH, and cell maturation. Three applications of MAFRF were performed in the vagina/vaginal introitus. During the treatment, six vaginal smears were obtained and stained with the Papanicolaou stain for determining the degree of cell maturation and with Gram stain for classification of vaginal flora, as per the criteria of Spiegel and Amsel. For vaginal pH determination, pH indicator strips were applied against the vaginal wall. Statistical analysis was performed using SPSS for Windows (version 17.0). Data were reported as mean±standard deviation. The differences were analyzed using the statistical method of generalized estimation equations with autoregressive correlation structure "1" and robust standard errors. RESULTS: The mean age was 59.8±4.2 years, and the mean time of menopause was 15.4±4.5 years. After treatment, there was an increase in the percentage of Lactobacillus spp. (p<0.001). Consequently, there was a progressive decrease in vaginal pH during the treatment (p<0.001). Regarding cell maturation, there was a decrease in the percentage of parabasal cells (p=0.001) and an increase in the rate of superficial cells (p<0.001). Additionally, there was an improvement in the VHI index. The mean VHI values before and after treatment were 13.2±5.6 and 22.5±3.7, respectively (p<0.001). CONCLUSION: MAFRF treatment is well tolerated and leads to improvement in the vaginal microenvironment.

Vulvar hemangioma: case report / Hemangioma vulvar: relato de caso

Abstract Hemangioma is a benign neoplasm that may affect the vulva, and it can cause functional or emotional disability. This article reports the case of a 52-year-old female patient with a history of a genital ulcer for the past 3 years and who had undergone various treatments with creams and ointments. The patient was biopsied and diagnosed with vulvar hemangioma and was subsequently submitted to surgical excision of the lesion. We emphasize the importance of following the steps of the differential diagnosis and proceeding with a surgical approach only if necessary.

Resumo O hemangioma é uma neoplasia benigna que pode afetar a vulva e pode causar incapacidade funcional ou emocional. Este artigo relata o caso de uma paciente de 52 anos com história de úlcera genital nos últimos 3 anos, submetida a diversos tratamentos com cremes e pomadas. A paciente foi biopsiada e diagnosticada com hemangioma vulvar e subsequentemente submetida a excisão cirúrgica da lesão. Ressaltamos a importância de seguir as etapas do diagnóstico diferencial e proceder a uma abordagem cirúrgica somente se necessário.

Pain and quality of life in breast cancer patients

OBJECTIVE: To evaluate the influence of pain on quality of life in breast cancer patients. METHODS: A cross-sectional study of 400 patients, including 118 without metastasis, 160 with loco-regional metastasis and 122 with distant metastasis. The instruments used were the European Organization for Research and Treatment for Cancer Quality of Life Questionnaire-Core 30 and the Breast Cancer-specific 23 and short McGill Pain Questionnaire. RESULTS: In total, 71.7% of patients reported pain. The most frequent sensory descriptor used by patients was 'jumping.' In the evaluative dimension, the main descriptor chosen was troublesome. The Global Health self-assessment showed pain to be inversely correlated with quality of life: the group without metastasis had a mean score of 55.3 (SD=24.8) for those in pain, which rose to 69.7 (SD=19.2) for those without pain (p=0.001). Subjects with loco-regional metastasis had score of 59.1 (SD=21.3) when in pain, and those without pain had a significantly higher score of 72.4 (SD=18.6) (p<0.001). Patients from the distant metastasis group showed similar results with a mean score of 48.6 (SD=23.1) for those in pain and 67.6 (SD=20.4) for those without pain (p=0.002). Regarding the association of pain intensity and quality of life, patients with distant metastasis and intense pain had the worst scores for quality of life with a functional scale mean of 49.9 (SD=17.3) (p<0.009), a Symptom Scale score of 50.0 (SD=20.1) (p<0.001) and a Global Health Scale score of 39.7 (SD=24.7) (p<0.006). CONCLUSIONS: Pain compromises the quality of life of patients with breast cancer, particularly those with advanced stages of the disease.

Correlação entre vaginose bacteriana e desfechos obstétricos desfavoráveis em mulheres brasileiras / Correlation between bacterial vaginosis and adverse obstetric outcomes in Brazilian women

Infecções vaginais e mudanças na flora vaginal são prevalentes durante a gravidez e têm sido associadas com desfechos obstétricos adversos, tais como trabalho de parto prematuro, amniorrexe prematura e baixo peso ao nascer. Objetivos: Correlacionar a presença de vaginose bacteriana (VB) com desfecho obstétrico desfavorável em mulheres brasileiras com gravidez no terceiro trimestre. Métodos: O estudo prospectivo observacional foi conduzido avaliando microbiota vaginal por bacterioscopia (a fresco e Gram) usando swab vaginal obtido de mulheres grávidas entre a 26 e a 32a semanas de gestação. As mulheres foram monitoradas até o parto, e os dados de seu seguimento e os demográficos foram coletados por meio de um questionário autoaplicável. Resultados: Foi diagnosticada VB, com base nos critérios de Amsel e de Nugent, em 77 mulheres entre as 190, demonstrando prevalência de 42.5%. VB foi significativamente associada com maior risco de parto prematuro (risk ratio [RR], 2.89; 95% intervalo de confiança [IC], 2.35­3.56) e de baixo peso ao nascer (RR, 2.17; 95%IC, 1.61­2.92). A rotura prematura das membranas não foi associada com VB. Conclusão: Foi constatada alta frequência de VB entre as mulheres brasileiras grávidas no terceiro trimestre, e a BV correlacionou-se com piores prognósticos da gravidez. O rastreio rotineiro de mulheres grávidas pode permitir um tratamento precoce e a prevenção de algumas complicações obstétricas

Vaginal infections and modifications in the vaginal flora are very prevalent during pregnancy and have been associated with adverse obstetric outcomes, such as preterm labor, preterm premature rupture of membranes and low birth weight. Objective: To evaluate the prevalence and associations of bacterial vaginosis (BV) and pregnancy outcomes among Brazilian pregnant women in the third trimester. Methods: A prospective observational study was conducted assessing vaginal microbiota on bacterioscopy (wet mount and Gram stain), using vaginal swabs obtained from pregnant women between 26 and 32 weeks' gestation. The women were monitored until delivery, and their pregnancy outcome and demographic data were collected using an interviewer-administered questionnaire. Results: BV was assessed using both Amsel's criteria and Nugent's score in 77 of 190 women, resulting in the prevalence of 42.5%. BV was significantly associated with preterm labor (risk ratio [RR], 2.89; 95% confidence interval [CI], 2.35­3.56) and low birth weight (RR, 2.17; 95%CI, 1.61­2.92). Premature rupture of membranes was not associated with BV. Conclusion: BV was found to be very frequent among Brazilian pregnant women in the third trimester and correlated to unfortunate pregnancy outcomes. Regular screening of pregnant women may allow for early treatment and prevention of some obstetric complications.
