Background: HPV test-based primary cervical screening is replacing cytology in Canada. In other countries, women's unpreparedness and concerns hindered the transition and post-implementation screening uptake. We investigated psychosocial correlates of intentions of screening in eligible individuals to participate in HPV-based primary cervical screening.

As Canadian provinces and territories prepare to transition to HPV-based primary screening for cervical cancer, failure to identify and address potential barriers to screening could hinder program implementation. We examined screening-eligible Canadians' attitudes towards and knowledge of cervical screening. A nationally representative sample of screening-eligible Canadians ( = 3724) completed a web-based survey in the summer of 2022.

The purpose of this paper is to provide evidence-based guidance on the management of a positive human papilloma virus (HPV) test and to provide guidance around screening and HPV testing for specific patient populations. The guideline was developed by a working group in collaboration with the Gynecologic Oncology Society of Canada (GOC), Society of Colposcopists of Canada (SCC), and the Canadian Partnership Against Cancer. The literature informing these guidelines was obtained through a systematic review of relevant literature by a multi-step search process led by an information specialist.

Pain during sexual intercourse, also called dyspareunia, affects most women after treatment for gynecological cancer. Previous work adopted a biomedical approach to depict dyspareunia in this population, which provided a narrow perspective of this condition. Taking into account women's experiences of dyspareunia and the factors influencing their care-seeking behaviors would provide insight to improve care in the context of gynecological cancer.

Objective: A novel cognitive-behavioral couple therapy (CBCT) has shown efficacy for treating provoked vestibulodynia (PVD), the most common type of genito-pelvic pain, in comparison to topical lidocaine. However, mechanisms of therapeutic change have not been determined. We examined women's and partners' pain self-efficacy and pain catastrophizing as mediators of change in CBCT, using topical lidocaine as a control group.

The disrupted introduction of the HPV-based cervical screening program in several jurisdictions has demonstrated that the attitudes and beliefs of screening-eligible persons are critically implicated in the success of program implementation (including the use of self-sampling). As no up-to-date and validated measures exist measuring attitudes and beliefs towards HPV testing and self-sampling, this study aimed to develop and validate two scales measuring these factors. In October-November 2021, cervical screening-eligible Canadians participated in a web-based survey.

Human papillomavirus-associated vulvar intraepithelial neoplasia (high-grade squamous intraepithelial neoplasia [HSIL] or VIN of usual type) is a lesion characterized by atypia extending from the basal layer to the upper epidermis. There are only rare reports of vulvar intraepithelial morphology exhibiting a pagetoid pattern of intraepithelial dissemination. We herein report two cases of vulvar HSIL in which a pagetoid pattern of spread and a largely uninvolved basal layer represented a diagnostic pitfall for extramammary Paget disease.

Pelvic floor muscle (PFM) training is the first-line treatment for women of all ages with urinary incontinence (UI), but evidence supporting its effects on the functional anatomy of the pelvic floor is scarce in older women. We aimed to evaluate the long-term (one-year) effects of PFM training on the shape of the levator hiatus (LH) in older women with UI and its association with PFM force, incontinence severity, and potential effect modifiers (age, UI severity, BMI, and UI type). This is a secondary analysis of the GROUP study, a non-inferiority RCT assessing the effects of a structured and progressive 12-week PFM training program to treat UI in older women.

Introduction And Hypothesis: Multimodal pelvic floor physical therapy (PFPT) is recommended after gynecological malignancies to treat dyspareunia. However, data to strongly support its implementation in the cancer care continuum are lacking. The aim of this study was to explore the views and experiences of gynecological cancer survivors with dyspareunia regarding the acceptability of multimodal PFPT.

The appropriate age at which to perform endometrial biopsy for abnormal uterine bleeding (AUB) is controversial. This study aimed to determine the prevalence of malignant and premalignant pathologies in women aged 41-49 years with AUB and without risk factors for endometrial cancer. Records of women who had undergone a biopsy at the gynaecology clinic of the Centre hospitalier de l'Université de Montréal between 2014 and 2018 were reviewed.

Background: The human papillomavirus (HPV) test has emerged as a significant improvement over cytology for primary cervical cancer screening. In Canada, provinces and territories are moving toward implementing HPV testing in cervical cancer screening programs. Although an abundance of research exists on the benefits of HPV-based screening, there is a dearth of research examining women's understanding of HPV testing.

Objective: The aim was to investigate whether pretreatment pain characteristics, psychological variables, and pelvic floor muscle (PFM) function predict the response to physical therapy (PT) in women with provoked vestibulodynia (PVD).

Materials And Methods: One hundred-five women diagnosed with PVD underwent 10 weekly sessions of individual PT comprising education, PFM exercises with biofeedback, manual therapy, and dilators. Treatment outcomes were evaluated at pretreatment, post-treatment, and 6-month follow-up and included pain intensity (numerical rating scale 0 to 10) and sexual function (Female Sexual Function Scale).

Background: Among women whose cervical specimens tested positive for high-risk human papillomaviruses (hrHPV) via the Hybrid Capture 2 assay in the Canadian Cervical Cancer Screening Trial (CCCaST), we assessed hrHPV genotype concordance between BD Onclarity HPV Assay and Roche's Linear Array, overall and stratified by hrHPV viral load. We also evaluated the performance of cytology, cytology combined with hrHPV genotyping (Onclarity assay) for HPV16/18 and non-HPV16/18 types, and hrHPV genotyping triage strategies for the detection of cervical intraepithelial neoplasia grade 2 or 3 and worse (CIN2+/CIN3+).

Methods: Standard measures (expected agreement, agreement, and κ values) were used to compare Onclarity to the reference test, Linear Array.

Background: A large proportion of gynecological cancer survivors suffer from pain during sexual intercourse, also known as dyspareunia. Following a multimodal pelvic floor physical therapy (PFPT) treatment, a reduction in pain and improvement in psychosexual outcomes were found in the short term, but no study thus far has examined whether these changes are sustained over time.

Purpose: To examine the improvements in pain, sexual functioning, sexual distress, body image concerns, pain anxiety, pain catastrophizing, painful intercourse self-efficacy, depressive symptoms and pelvic floor disorder symptoms in gynecological cancer survivors with dyspareunia after PFPT, and to explore women's perceptions of treatment effects at one-year follow-up.

Article Synopsis
  • Anyplex II HPV-28 can individually detect 28 HPV genotypes, and a study compared its effectiveness against linear array HPV genotyping (LA-HPV) in 410 anogenital samples from individuals, primarily women.
  • The detection rates showed that HPV-28 identified HPV in 95.9% of samples, while LA-HPV detected it in 93.2%, leading to a high agreement rate of 96.3% between the two methods.
  • Both methods had excellent concordance for most HPV types, especially for high-risk genotypes, but HPV-28 was more often positive for specific types like HPV42 and HPV68.
