Chemicals in menstrual products: A systematic review.

BACKGROUND: From menarche until menopause, the average menstruator will use over 11 000 tampons or sanitary pads. Vaginal and vulvar tissue is highly permeable, and chemicals are absorbed without undergoing first-pass metabolism. OBJECTIVES: To conduct a review of the literature to determine exposure to environmental chemicals in menstrual products. SEARCH STRATEGY: This review identified 15 papers over the past 10 years. SELECTION CRITERIA: Papers that measured chemicals in menstrual products and that measured human biomarkers of chemical exposure were included. Papers had to also be available in English. DATA COLLECTION AND ANALYSIS: Reviewers assessed the articles and data provided. Multiple chemical groups were found. MAIN RESULTS: Phthalates, volatile organic compounds, parabens, environmental phenols, fragrance chemicals, dioxins and dioxin-like compounds were detected in menstrual products. Research gaps were identified, including the lack of studies on newer products such as menstrual underwear and cups/discs. In addition to measuring chemicals in these products, future research should focus on clarifying the exposure per menstrual cycle to these chemicals to understand how menorrhagia and cycle length influence exposure from menstrual products. CONCLUSION: Menstrual products contained measurable levels of a range of endocrine disrupting chemicals including phthalates, phenols and parabens. This reflects a potentially important route of exposure to chemicals that can impact women's reproductive health.

Menstrual Tampons Are Reliable and Acceptable Tools to Self-Collect Vaginal Microbiome Samples.

Many women report embarrassment as the cause for their avoidance of routine gynaecological screening appointments. Methods of self-collection of bio samples would perhaps encourage women to participate in routine screening programs. The vaginal microbiome plays a key role in women's health and reproductive function. Microbial disturbances can result in the loss of lactobacillus dominance, also known as dysbiosis, associated with an increased risk of contracting sexually transmitted infections (STIs), pregnancy complications and infertility. Our primary aim was to determine if vaginal microbiome screening results are comparable between two methods for self-collected sample acquisition: tampons and lower vaginal swabs (LVSs). Secondary aims included the assessment of the effect of pre-analytic storage on the data (to streamline processing), the prevalence of dysbiosis and the acceptability of the tampons to the participants. Statistical analysis revealed no significant difference in the microbiome data, from tampons versus LVSs or fresh versus frozen samples. The prevalence of dysbiosis in this population of healthy volunteers was 42.9%. The questionnaire data revealed that 52.4% of volunteers use tampons every period, and the majority of volunteers rated the tampons as 5 on a 1-5 Likert scale regarding their perceived comfort using tampons. All (100%) of volunteers were happy to provide a tampon as a sample for testing. The findings from this study show that tampons and LVSs were comparable when analysing the vaginal microbiome, with potential superiority of the tampon with regard to patient acceptability. Self-collection of vaginal secretions for gynaecological screening using tampons warrants further research as this could change the screening landscape, ensuring wider participation and increasing efficacy.

Menstrual Toxic Shock Syndrome: A French Nationwide Multicenter Retrospective Study.

BACKGROUND: Studies describing the clinical features and short-term prognosis of patients admitted to the intensive care unit (ICU) for menstrual toxic shock syndrome (m-TSS) are lacking. METHODS: This was a multicenter retrospective cohort study of patients with a clinical diagnosis of m-TSS admitted between 1 January 2005 and 31 December 2020 in 43 French pediatric (n = 7) or adult (n = 36) ICUs. The aim of the study was to describe the clinical features and short-term prognosis, as well as to assess the 2011 Centers for Disease and Control (CDC) diagnostic criteria, in critically ill patients with m-TSS. RESULTS: In total, 102 patients with m-TSS (median age, 18 years; interquartile range, 16-24 years) were admitted to 1 of the participating ICUs. All blood cultures (n = 102) were sterile. Methicillin-sensitive Staphylococcus aureus grew from 92 of 96 vaginal samples. Screening for superantigenic toxin gene sequences was performed for 76 of the 92 vaginal samples positive for S. aureus (83%), and toxic shock syndrome toxin 1 was isolated from 66 strains (87%). At ICU admission, no patient met the 2011 CDC criteria for confirmed m-TSS, and only 53 (52%) fulfilled the criteria for probable m-TSS. Eighty-one patients (79%) were treated with antitoxin antibiotic therapy, and 8 (8%) received intravenous immunoglobulins. Eighty-six (84%) patients required vasopressors, and 21 (21%) tracheal intubation. No patient required limb amputation or died in the ICU. CONCLUSIONS: In this large multicenter series of patients included in ICUs for m-TSS, none died or required limb amputation. The CDC criteria should not be used for the clinical diagnosis of m-TSS at ICU admission.

Quantifying procedural pain associated with office gynecologic tract sampling methods.

OBJECTIVE: Emerging technologies may enable detection of endometrial cancer with methods that are less invasive than standard biopsy methods. This study compares patient pain scores among 3 office gynecologic tract sampling methods and explores their potential determinants. METHODS: A prospective study including 3 sampling methods (tampon, Tao brush (TB), endometrial biopsy (EB)) was conducted between December 2015 and August 2017 and included women ≥45 years of age presenting with abnormal uterine bleeding, postmenopausal bleeding, or thickened endometrial stripe. Patients rated pain after each sampling procedure using a 100-point visual analog scale (VAS). RESULTS: Of 428 enrolled, 190 (44.39%) patients underwent all 3 sampling methods and reported a VAS score for each. Nearly half were postmenopausal (n = 93, 48.9%); the majority were parous (172, 90.5%) of which 87.8% had at least one vaginal delivery. Among the 190 patients, the median (IQR) pain score was significantly lower for sampling via tampon (0 [0,2]) compared to TB (28 [12, 52]) or EB (32 [15, 60]) (both p < 0.001, Wilcoxon signed rank test). Among women who underwent tampon sampling, age and pain scores showed a weak positive correlation (Spearman rank correlation, r = 0.14; p = 0.006); EB sampling was associated with a weak inverse correlation between parity and pain scores (r = -0.14; p = 0.016). CONCLUSION: Gynecologic tract sampling using a tampon had significantly lower pain than both EB and TB. Pain with tampon sampling was positively correlated with age and pain with EB sampling was inversely correlated with parity. Pain scores for TB and EB were not significantly related to age, menopausal status, or BMI.

The Tampon Test as a Primary Outcome Measure in Provoked Vestibulodynia: A Mixed Methods Study.

BACKGROUND: Provoked vestibulodynia (PVD) is characterized by severe pain, often induced by penetrative sex. This may lead to women abstaining from sexual intercourse, hence the recording of pain intensity levels in PVD research is often challenging. The standardized tampon test was designed as an alternative outcome measure to sexual intercourse pain and has frequently been used in clinical studies. AIM: The aim of this mixed methods study is to evaluate the tampon test as a primary outcome measure for an upcoming randomized clinical trial for women with PVD. METHODS: An explanatory sequential design was applied, integrating quantitative and qualitative methods. In phase one, pain intensity levels were evaluated with the tampon test amongst 10 women, aged 18-33, with PVD. The test was repeated on day 1, 7 and 14. Pain intensity was rated on the Numerical Rating Scale (NRS), (0-10), 10 being worst possible pain. In phase two, the participants' experiences with the test were explored with semi-structured interviews using a descriptive and inductive qualitative design. All participants were recruited from the Vulva Clinic, Oslo University Hospital, Norway. OUTCOMES: The tampon test data and interviews were brought together to see how the interviews could refine and help to explain the quantitative findings. RESULTS: The tampon test data demonstrated large intra- and inter-individual variability. Median tampon pain intensity was 4.5 (min=1.7; max=10; Q1=2.5; Q3=6). Many experienced the test as an inadequate representation of pain during intercourse as it was less painful, different in nature and conducted in an entirely different context. Four participants had a mean score of four or lower on the NRS, whilst concurrently reporting high levels of pain during sexual intercourse. CLINICAL IMPLICATIONS: The findings indicate that the tampon test may underestimate severity of pain among some women with PVD. Participants with low pain scores would be excluded from studies where the tampon test is part of the trial eligibility criteria, even though severe pain was experienced during sexual intercourse. Large intra-individual variability in pain scores also reduces the test's ability to register clinical meaningful changes and hence necessitates repeated measurements per assessment time point. CONCLUSION: Although the tampon test has many advantages, this study indicates several potential problems with the application of the test as a primary outcome measure in PVD. In our opinion the test is most useful as a secondary outcome, preferably undertaken repeatedly in order to increase precision of the pain estimation. Kaarbø MB, Danielsen KG, Haugstad GK, et al.

Intracellular pH regulation and the acid delusion.

The hydrogen ion concentration ([H+]) in intracellular cytoplasmic fluid (ICF) must be maintained in a narrow range in all species for normal protein functions. Thus, mechanisms regulating ICF are of fundamental biological importance. Studies on the regulation of ICF [H+] have been hampered by use of pH notation, failure to consider the roles played by differences in the concentration of strong ions (strong ion difference, SID), the conservation of mass, the principle of electrical neutrality, and that [H+] and bicarbonate ions [HCO3-] are dependent variables. This argument is based on the late Peter Stewart's physical-chemical analysis of [H+] regulation reported in this journal nearly forty years ago (Stewart. 1983. Can. J. Physiol. Pharmacol. 61: 1444-1461. Doi:10.1139/y83-207). We start by outlining the principles of Stewart's analysis and then provide a general understanding of its significance for regulation of ICF [H+]. The system may initially appear complex, but it becomes evident that changes in SID dominate regulation of [H+]. The primary strong ions are Na+, K+, and Cl-, and a few organic strong anions. The second independent variable, partial pressure of carbon dioxide (PCO2), can easily be assessed. The third independent variable, the activity of intracellular weak acids ([Atot]), is much more complex but largely plays a modifying role. Attention to these principles will potentially provide new insights into ICF pH regulation.

Thrombus formation and ischemic necrosis of the uterus and adnexa due to purpura fulminans: A case report.

Purpura fulminans (PF) is a syndrome characterized by the sudden onset of progressive skin hemorrhage, necrosis of the extremities, and thrombotic occlusion. Although the cause is believed to be protein C deficiency, many aspects of this syndrome have yet to be clarified. A 45-year-old Japanese woman, G2P2 (vaginal delivery), developed fever and lower abdominal pain. It was her 5th day of menstruation, and a tampon had been in the vagina for a few days. Septic shock and disseminated intravascular coagulation were diagnosed, and multidisciplinary treatment was started. Also, toxic shock syndrome due to tampon use was suspected. The purpura on the limbs turned into blisters and then blackish-purple spots, leading to hemorrhagic necrosis within a few days. Moreover, imaging showed that the uterus and both adnexa had enlarged significantly, and raised suspicion of abscess formation. Total hysterectomy and bilateral adnexectomy were performed, and the histopathological diagnosis was hemorrhagic necrosis due to extensive thrombus formation. In men, PF affects the scrotum and penis, leading to autoamputation of the male genitalia, while there are no reports of PF involving the female genitalia. Regarding the PF, in this case, we considered the possibility of pathologic conditions progressing to the female genitalia.

Combining copy number, methylation markers, and mutations as a panel for endometrial cancer detection via intravaginal tampon collection.

OBJECTIVE: We aimed to assess whether endometrial cancer (EC) can be detected in shed DNA collected with vaginal tampon by analyzing copy number, methylation markers, and mutations. METHODS: Tampons were collected prior to hysterectomy from 38 EC patients and 28 women with benign indications. Extracted tampon DNA underwent the following: 1) low-coverage whole genome sequencing (LC-WGS) to assess copy number, 2) pyrosequencing to measure percent promotor methylation of HOXA9, RASSF1, and CDH13 and 3) next generation sequencing (NGS) to identify mutations in 19 genes associated with EC identified through The Cancer Genome Atlas. Sensitivity and specificity for each test and test combinations were calculated. RESULTS: Methylation analysis yielded the highest specificities but lowest sensitivities (37-40% sensitivity; 100% specificity for HOXA9, RASSF1 and HTR1B) while mutation analysis had improved sensitivity (50% sensitivity; 83% specificity). Only one "false positive" result for copy number variants was identified among women with benign surgical indications, which was based on detection of copy number changes, and associated with a leiomyosarcoma that was only recognized at hysterectomy. Considering any of the 3 biomarker classes as a positive, resulted in a sensitivity of 92% and specificity of 86%. Mutation analysis did not add sensitivity to the combination of analysis of copy number and methylation. CONCLUSIONS: This study demonstrates a proof-of-principle for non-invasive yet precise detection of endometrial cancer. We propose that with improved biomarker testing, it may be possible to develop a clinically useful test for detecting EC.

Sensitizing fragrances in absorbent hygiene products.

BACKGROUND: Allergenic fragrances are present in a wide range of products but they are not regulated in all industries to the same extent. In Europe, absorbent hygiene products (AHPs) are only covered by the general product safety directive and therefore fragrances can be used freely, whereas in cosmetics and toys the use of these ingredients is regulated. METHOD: An analytical method was developed to evaluate the presence of 24 sensitizing fragrances in AHPs. This method allows simultaneous identification and quantification and was validated using the total error approach with an acceptance value of ±15%. RESULTS: The validated method was applied to evaluate 10 scented AHPs consisting of four tampons, three panty liners, and three sanitary pads. Eight allergenic fragrances were identified in these products and five products contained at least one allergen above 10 µg/g. CONCLUSION: The presence of these allergens is not communicated to the consumer. This is, however, a strict requirement in other industries (eg, cosmetics, toys) to ensure adequate consumer protection. Knowing that the exposed area is more susceptible to allergens and irritants, the presence of these allergens should be disclosed.

[Staphylococcal toxic shock syndrome should be considered in the event of diffuse erythema with fever and shock]. / Érythème généralisé fébrile et choc : choc toxinique staphylococcique.

BACKGROUND: Toxic shock syndrome (TSS) was first described by Todd in 1978. The relevant Lancet publication reported 7 cases of children with fever, exanthema, hypotension and diarrhoea associated with multiple organ failure. An association between TSS and use of hyper-absorbent tampons in menstruating women was discovered in the 1980s. Following the market withdrawal of such tampons, TSS virtually disappeared. Herein we report a new case of TSS in a 15-year-old girl. PATIENTS AND METHODS: A 15-year-old patient was admitted to intensive care for severe sepsis and impaired consciousness associated with diffuse abdominal pain. Dermatological examination revealed diffuse macular exanthema. Laboratory tests showed hepatic cytolysis (ASAT 101 U/L, ALAT 167 U/L, total bilirubin 68µmol/L) and an inflammatory syndrome. Lumbar puncture and blood cultures were sterile while thoraco-abdomino-pelvic and brain scans were normal. The patient was menstruating and had been using a tampon over the previous 24hours. Vaginal sampling and tampon culture revealed TSST-1 toxin-producing S. aureus. Management consisted of intensive care measures and treatment with amoxicillin-clavulanic acid and clindamycin for 10 days. CONCLUSION: In case of septic shock associated with diffuse macular exanthema a diagnosis of TSS must be envisaged, particularly in menstruating women.

Impact of Currently Marketed Tampons and Menstrual Cups on Staphylococcus aureus Growth and Toxic Shock Syndrome Toxin 1 Production In Vitro.

Fifteen currently marketed intravaginal protection products (11 types of tampon and 4 types of menstrual cup) were tested by the modified tampon sac method to determine their effect on Staphylococcus aureus growth and toxic shock syndrome toxin 1 (TSST-1) production. Most tampons reduced S. aureus growth and TSST-1 production, with differences based on brand and composition, and the level of S. aureus growth was higher in destructured than in unaltered tampons. We observed higher levels of S. aureus growth and toxin production in menstrual cups than in tampons, potentially due to the additional air introduced into the bag by cups, with differences based on cup composition and size.IMPORTANCE Menstrual toxic shock syndrome is a rare but severe disease. It occurs in healthy women vaginally colonized by Staphylococcus aureus producing toxic shock syndrome toxin 1 using intravaginal protection, such as tampons or menstrual cups. Intravaginal protection induces TSS by the collection of catamenial products, which act as a growth medium for S. aureus Previous studies evaluated the impact of tampon composition on S. aureus producing toxic shock syndrome toxin 1, but they are not recent and did not include menstrual cups. This study demonstrates that highly reproducible results for S. aureus growth and TSST-1 production can be obtained by using a simple protocol that reproduces the physiological conditions of tampon and cup usage as closely as possible, providing recommendations for tampon or cup use to both manufacturers and consumers. Notably, our results do not show that menstrual cups are safer than tampons and suggest that they require similar precautions.

Contribution of toxic shock syndrome toxin-1 to systemic inflammation investigated by a mouse model of cervicovaginal infection with Staphylococcus aureus.

Toxic shock syndrome toxin-1 (TSST-1), a superantigen produced by Staphylococcus aureus is a causative agent of toxic shock syndrome (TSS) that is frequently associated with tampon use. It has long been suggested that TSS is induced when TSST-1 circulates through the body. However, the systemic distribution of TSST-1 from vagina or uterus has never been demonstrated. In this study, a mouse cervicovaginal infection model was established. Transcervical inoculation with a virulence strain of S. aureus and its derivative TSST-1-deficient mutant demonstrated that TSST-1 distributed to the bloodstream and spleen, and promoted systemic inflammation without bacteremia. Transcervical administration with the wild-type toxin and a superantigen-deficient mutant of TSST-1 (mTSST-1) demonstrated that the superantigenic activity of TSST-1 was essential to stimulate the systemic inflammation. Furthermore, this activity was not promoted by co-transcervical inoculation with lipopolysaccharides. The circulating TSST-1 and systemic inflammation rapidly reduced at 48 h after administration, suggesting that persistence of S. aureus in the uterus may be involved in long-term complications of TSS. Transcervical inoculation with mTSST-1-producing S. aureus showed that this toxin promoted bacterial number, uterine tissue damage, and localization of bacterial cells around uterine cavity. The results suggest that TSST-1 enhances S. aureus burden in uterine cavity, the secreted TSST-1 distributes into circulation system, and then systemic inflammation is induced.

Use of Hemostatic Nasal Plugs in Emergency Medical Services in the Netherlands: A Prospective Study of 33 Cases.

BACKGROUND: Epistaxis is a common medical emergency with possible life-threatening complications. In the prehospital setting, epistaxis can be treated with nasal tampons. HemCon® Nasal Plug is a nasal tampon impregnated with oxidized cellulose, which has hemostatic properties. OBJECTIVE: The objective of this study was to determine the effectiveness and usability of HemCon Nasal Plugs in the treatment of severe epistaxis in the prehospital setting. METHODS: From June 2012 to December 2014, all ambulances of two emergency medical services in the Netherlands were equipped with HemCon Nasal Plugs. The plug was used according to protocol; if conventional treatment failed to control severe epistaxis or if conventional treatment was unlikely to achieve hemostasis. The ambulance personnel filled in an evaluation form after each use. RESULTS: A total of 33 patients were treated with HemCon Nasal Plugs. Twenty-four patients were taking anticoagulants or suffered from a clotting disorder. The cause of epistaxis was idiopathic in the majority of the patients. Inserting HemCon Nasal Plugs resulted in cessation of epistaxis in 25/33 patients and resulted in reduction of epistaxis in 4/33 patients. HemCon Nasal Plugs failed to control epistaxis in 4/33 patients, possible due to an unreachable site of bleeding. CONCLUSION: This study demonstrated that HemCon Nasal Plug is an effective adjunct in the prehospital treatment of severe and uncontrolled epistaxis.

Effects of polymer-based, silver nanoparticle-coated silicone splints on the nasal mucosa of rats.

Infection is a serious complication after nasal packing that otolaryngologists seek to avoid. The aim of this study is to investigate the use of silver (Ag) nanoparticle, which serves as antimicrobial agents, with nasal tampons. The study design is an experimental animal model and the setting is tertiary referral center. Twenty-four rats were randomized into the following four groups: (1) control group (n = 6); (2) silicone nasal splint (SNS) group (n  =  6); (3) polypropylene-grafted polyethylene glycol (PP-g-PEG) amphiphilic graft copolymer-coated SNS group (n  =  6); and (4) Ag nanoparticle-embedded PP-g-PEG (Ag-PP-g-PEG) amphiphilic graft copolymer-coated SNS group (n  =  6). These tampons were applied to rats for 48 h, after which they were removed in a sterile manner, and the rats were sacrificed. The nasal septa of the rats were excised, and assessments of tissue changes in the nasal mucosa were compared among the groups. The removed tampons were microbiologically examined, and quantitative analyses were made. When the groups were compared microbiologically, there were no significant differences in bacterial colonization rates of coagulase-negative Staphylococcus spp. among the three groups (p = 0.519), but there was a statistically significant difference among bacterial colonization rates of Heamophilus parainfluenzae and Corynebacterium spp. (p = 0.018, p = 0.004). We found that H. parainfluenzae grew less robustly in the Ag-PP-g-PEG than the PP-g-PEG group (p = 0.017). However, we found no significant difference between the Ag-PP-g-PEG and SNS groups, or between the SNS and PP-g-PEG groups. The growth of Corynebacterium spp. did not differ significantly between the Ag-PP-g-PEG and SNS groups (p = 1.000). When Group 4 was compared with Group 2, the former showed less inflammation. Compared with other tampons, Ag-PP-g-PEG amphiphilic graft copolymer-coated silicone nasal tampons caused less microbiological colonization and inflammation. Therefore, the use of these tampons may prevent secondary infections and reduce the risk of developing complications by minimizing tissue damage.

Preparation and characterization of textile-based carrier systems for anal fissure treatment.

Anal fissure is common and painful disease of anorectum. In this study, microparticles containing nifedipine and lidocaine HCl were prepared by spray drying and applied to bio-degradable and bio-stable tampons. Characterization of microparticles was determined by visual analyses, mass yield, particle size measurement, encapsulation efficiency, drug loading and in vitro drug release. Mass yield was between 5.5 and 45.9%. The particle size was between 15.1 and 26.8 µm. Encapsulation efficiency were 96.142 ± 5.931 and 85.571 ± 3.301; drug loading were 65.261 ± 3.914% and 37.844 ± 4.339% of L2 and N1, respectively. Well-separated, mainly spherical microparticles with suitable properties were obtained. Optimum microparticles were applied to tampons. Physical properties and visual characteristics of tampons were investigated before and after binder application. In vitro drug release from tampons were also examined. According to the results, textile-based carrier systems loaded microparticles containing nifedipine and lidocaine HCl will be an effective and promising alternative for current anal fissure treatment.

Detection of endometrial cancer via molecular analysis of DNA collected with vaginal tampons.

OBJECTIVE: We demonstrate the feasibility of detecting EC by combining minimally-invasive specimen collection techniques with sensitive molecular testing. METHODS: Prior to hysterectomy for EC or benign indications, women collected vaginal pool samples with intravaginal tampons and underwent endometrial brushing. Specimens underwent pyrosequencing for DNA methylation of genes reported to be hypermethylated in gynecologic cancers and recently identified markers discovered by profiling over 200 ECs. Methylation was evaluated individually across CpGs and averaged across genes. Differences between EC and benign endometrium (BE) were assessed using two-sample t-tests and area under the curve (AUC). RESULTS: Thirty-eight ECs and 28 BEs were included. We evaluated 97 CpGs within 12 genes, including previously reported markers (RASSF1, HSP2A, HOXA9, CDH13, HAAO, and GTF2A1) and those identified in discovery work (ASCL2, HTR1B, NPY, HS3ST2, MME, ADCYAP1, and additional CDH13 CpG sites). Mean methylation was higher in tampon specimens from EC v. BE for 9 of 12 genes (ADCYAP1, ASCL2, CDH13, HS3ST2, HTR1B, MME, HAAO, HOXA9, and RASSF1) (all p<0.05). Among these genes, relative hypermethylation was observed in EC v. BE across CpGs. Endometrial brush and tampon results were similar. Within tampon specimens, AUC was highest for HTR1B (0.82), RASSF1 (0.75), and HOXA9 (0.74). This is the first report of HOXA9 hypermethylation in EC. CONCLUSION: DNA hypermethylation in EC tissues can also be identified in vaginal pool DNA collected via intravaginal tampon. Identification of additional EC biomarkers and refined collection methods are needed to develop an early detection tool for EC.

A prospective double-blind cross-sectional study of the accuracy of the use of dry vaginal tampons for self-sampling of human papillomaviruses.

OBJECTIVE: To evaluate if a dry vaginal tampon can be used to accurately detect high-risk human papillomaviruses (HPV) and so be used as a cervical screening tool for the early detection of high-grade cervical intraepithelial neoplasia (CIN2+). DESIGN: Prospective double-blinded cross-sectional study. SETTING: Colposcopy unit in North London. POPULATION: Women referred for colposcopy with both abnormal and normal cervical cytology were invited to participate in this study. METHODS: Women inserted a dry tampon in the vagina before colposcopic examination. Polymerase chain reaction (PCR) HPV test was carried out on the dry tampon. Cervical samples were collected by the colposcopist for HPV testing using Hybrid Capture (an HC2 kit). MAIN OUTCOME MEASURE: Detection of CIN2+. RESULTS: In all, 501 women participated in the study. The majority of participants (69%) were in the 25-35-year age group. Overall sensitivity and specificity for detection of CIN2+ by vaginal tampon were 76% (95% confidence interval [95% CI] 65-85) and 61% (95% CI 56-66), respectively, and HC2 had a sensitivity of 92% (95% CI 83-97) with a specificity of only 46% (95% CI 41-51). Sensitivity ratio was 0.83 (95% CI 0.73-0.94) (P = 0.004) and Specificity ratio for CIN2+ was 1.33 (95% CI 1.22-1.45). Indicating that the tampon test was significantly (P < 0.0001) more specific. Sensitivity decreased and specificity improved with increasing age. CONCLUSIONS: Dry tampon test showed reasonably high sensitivity and specificity when detecting CIN2+. The majority of participants (98%) approved of the use of dry tampons as a method of sample collection, which could be an effective alternative method for detecting HPV infection.

The impact of vaginal penetration difficulties on the sexual functioning of women and their male partners.

OBJECTIVES: To compare the sexual function of women with and without vaginal penetration difficulties (VPDs) and relate it to the sexual function of their male partners. METHODS: All consenting women attending a sexual medicine centre during 2005-2007 completed the Female Sexual Function Index (FSFI) and answered questions about five VPDs (placement of a tampon, gynaecological examination, insertion of her or her partner's finger, and penile-vaginal intercourse). Male partners filled the International Index of Erectile Function (IIEF). RESULTS: Full data were available for 223 women, and 118 male partners. Male partners of women with VPDs (n = 53) had lower sexual desire (p = 0.0225). The number of VPDs in the women concerned negatively correlated with their partners' desire (r = - 0.18339, p = 0.0468) and erectile function (r = - 0.19848, p = 0.0312). All women with at least one VPD (n = 109) reported significantly more sexual pain (p < 0.0001) and had worse sexual function scores (p = 0.014) than women with no VPDs (n = 114). Women with VPDs other than penile-vaginal penetration had worse orgasmic functioning (p = 0.0119). CONCLUSIONS: The women's VPDs are correlated with worse sexual functioning for them and for their male partners. The five VPDs are a practical and useful tool for identifying impaired sexual functioning.

Cotton Fibers with a Lactic Acid-Like Surface for Re-establishment of Protective Lactobacillus Microbiota by Selectively Inhibiting Vaginal Pathogens.

Failure to reconstruct the Lactobacillus microbiota is the major reason for the recurrence of vaginal infection. However, most empiric therapies focus on the efficacy of pathogen elimination but do not sufficiently consider the viability of Lactobacillus. Herein, cotton fibers with a lactic acid-like surface (LC) are fabricated by NaIO4 oxidation and L-isoserine grafting. The lactic acid analog chain ends and imine structure of LC can penetrate cell walls to cause protein cleavage in Escherichia coli and Candida albicans and inhibit vaginal pathogens. Meanwhile, the viability of Lactobacillus acidophilus is unaffected by the LC treatment, thus revealing a selective way to suppress pathogens as well as provide a positive route to re-establish protective microbiota in the vaginal tract. Moreover, LC has excellent properties such as good biosafety, antiadhesion, water absorption, and weight retention. The strategy proposed here not only is practical, but also provides insights into the treatment of vaginal infections.

A pharmacist's role in increasing access to menstrual products: an education and advocacy approach.

Individuals who menstruate grapple with diverse challenges in menstrual and reproductive health. This includes financial burdens, societal stigmas, and negative mental and physical health implications. Period poverty, marked by insufficient access to menstrual products, education, and sanitation, remains a prevalent and poorly addressed issue. Alarming statistics highlight the extent of this problem and shed light on the staggering number of individuals lacking access to essential menstrual products. The discourse extends to the safety and accessibility of a diverse array of menstrual products. A comprehensive comparison of the cost of available period products was conducted using data obtained from various retail websites. The often-overlooked potential indirect expenses and profound impacts on quality of life were also discussed. Amidst other public health initiatives, pharmacists have emerged as pivotal advocates and educators. Pharmacists are poised to drive initiatives that increase access to menstrual products through public health education and advocacy. By providing education on different menstrual product options, pharmacists can empower individuals to make informed decisions based on their needs. This perspective illuminates the complex impacts of menstruation on individuals and proposes that pharmacists can play a role in overcoming barriers to access. The proposed strategies, rooted in education, research, and advocacy, pave the way for enhancing access, reducing stigma, and elevating the quality of life for those navigating the intricate complexities of menstruation.
