Abstract Introduction Neuroproliferative vestibulodynia has been proposed as a subtype of vulvodynia characterized by an increase in nerve growth factor (NGF) expression and nerve fiber density in the vulvar vestibule, leading to superficia…

Predictive tools are lacking for pain-related outcomes after endometriosis surgery. The objective of this study was to develop and validate a machine learning-based clinical model to predict poor pain-related quality of life after endometri…

OBJECTIVE: To characterize differences between individuals with and without mid-cycle pain in a registry cohort with endometriosis. DESIGN: Prospective analysis of data from the Endometriosis Pelvic Pain Interdisciplinary Cohort Data Regis…

Endometriosis contributes to 5-21% of hospital admissions for pelvic pain. While hormonal therapies are pivotal in managing endometriosis-related pain, no single hormonal treatment suits all patients. We aimed to assess the effectiveness an…

To correlate pain-related phenotyping for central nervous system sensitization in endometriosis-associated pain with mental health outcomes during the COVID-19 pandemic, the prospective Endometriosis and Pelvic Pain Interdisciplinary Cohort…

OBJECTIVES: To prospectively evaluate pain-related quality-of-life (Endometriosis Health Profile-30 [EHP-30] pain subscale) after surgery at an interdisciplinary centre of expertise for endometriosis and pelvic pain. METHODS: A prospective…

STUDY QUESTION: Is there an association between the somatic loss of PTEN (phosphatase and tensin homolog) and ARID1A (AT-rich interaction domain 1A) and endometriosis disease severity and worse clinical outcomes? SUMMARY ANSWER: Somatic PTE…

Endometriosis-associated dyspareunia can persist after surgical interventions, requiring multidisciplinary treatment including pain education. This study explored the effectiveness of a one-day workshop for improving knowledge, behavioural …

Importance: A subset of people who undergo surgery for endometriosis have persistent pain, suggesting that other factors besides the endometriosis, such as central sensitization, may play a role in this pain. The Central Sensitization Inven…

The clinical phenotype of somatic mutations in endometriosis is unknown. The objective was to determine whether somatic KRAS mutations were associated with greater disease burden in endometriosis (i.e. more severe subtypes and higher stage)…

ABSTRACT: A key clinical problem is identifying the patient with endometriosis whose pain is complicated by central nervous system sensitization, where conventional gynecologic treatment (eg, hormonal therapy or surgery) may not completely …

STUDY OBJECTIVE: Endometriosis fertility index (EFI) is a robust tool to predict the pregnancy rate in patients with endometriosis who are attempting non-in vitro fertilization conception. However, EFI calculation requires laparoscopy. Newl…

Background: Endometriosis is a complex condition that can negatively affect a woman's quality of life, including her sleep. This study aims to assess the multifactorial variables associated with poorer quality of sleep in women with endomet…

STUDY QUESTION: What are the use patterns and factors associated with combined hormonal contraception (CHC) ineffectiveness or discontinuation due to side-effects in patients with endometriosis and pelvic pain? SUMMARY ANSWER: Worse chronic…

INTRODUCTION: Deep dyspareunia is a cardinal symptom of endometriosis, and as many as 40% of people with this condition experience comorbid superficial dyspareunia. AIM: To evaluate the relationship between sexual pain and infertility conce…

Chronic pelvic pain affects one in seven women worldwide, and there is an urgent need to reduce its associated significant costs and to improve women's health. There are many correlated factors associated with chronic pelvic pain (CPP), and…

INTRODUCTION: Deep dyspareunia, a common symptom in endometriosis, has previously been associated with bladder and/or pelvic floor tenderness (BPFT), which suggests a role for central nervous system sensitization. The Central Sensitization …
