Endometriosis-associated chronic pelvic pain can at times be a complex problem that is resistant to standard medical and surgical therapies. Multiple comorbidities and central sensitization may be at play and must be recognized with the hel…

Endometriosis has yielded controversy on whether it constitutes a single disease or distinct types. Current classification systems poorly correlate with the severity of symptoms and do not provide prognostic tools that can guide management …

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…

The pathogenesis of bowel endometriosis is multifactorial. There is a predilection for disease of the rectum/sigmoid colon because refluxed endometrium is more likely to settle in the pouch of Douglas and its movement is delimited by the si…

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 …

Une femme de 33 ans avec antécédents d'endométriose manifestait des douleurs après l'orgasme accompagnées de métrorragies, de nausées, de transpiration et d'épuisement. Les antécédents et les résultats d'examen de la patiente indiquent une …

STUDY QUESTION: Does interleukin-1β (IL-1β) play a role in promoting nerve growth factor expression, neurogenesis and deep dyspareunia in endometriosis? SUMMARY ANSWER: IL-1β directly stimulates nerve growth factor (NGF) expression in endo…

Endometriosis is a common reproductive condition in women, with multiple implications for sexual health. It is present in approximately one in ten women of reproductive age. The most favored hypothesis for the etiology of endometriosis invo…

PURPOSE OF REVIEW: The purpose of this review is to summarize and highlight recent critical advances in the diagnosis, classification, and management of adenomyosis. RECENT FINDINGS: Recent studies have clarified the specific mechanism thr…

Endometriosis, a systemic disease that is often painful and chronic, affects ∼10% of reproductive-age women. The disease can have a negative impact on a patient's physical and emotional well-being, quality of life, and productivity. Endomet…

INTRODUCTION: Dyspareunia has been traditionally divided into superficial (introital) dyspareunia and deep dyspareunia (pain with deep penetration). While deep dyspareunia can coexist with a variety of conditions, recent work in endometrios…

Background Dyspareunia is a classic symptom of endometriosis but is neglected in research and clinical contexts. This study explored the experience of this endometriosis-associated sexual pain. Methods This was a qualitative descriptive stu…

OBJECTIVE: To systematically review and perform a meta-analysis of the risk of ectopic pregnancy in endometriosis. DATA SOURCES: MEDLINE (OVID), Embase (OVID), CINAHL (EBSCO), and Cochrane Library to April 1, 2019. Inclusion criteria were …

OBJECTIVE: This study sought to identify factors independently associated with a negative impression of the medical profession in patients with endometriosis who were presenting to a tertiary referral centre. METHODS: A cross-sectional ana…

STUDY OBJECTIVE: To describe the hospital-associated cost of endometriosis in Canada from April 2008 to March 2013. DESIGN: Population-based descriptive study. SETTING: Canada, with the exception of the province of Quebec. PATIENTS: All …

The advent of next generation sequencing has vastly improved the resolution of mutation detection, thereby both increasing the resolution of the analysis of cancer tissues and shining light on the existence of somatic driver mutations in no…

Abstract The presence of somatic driver mutations in endometriosis has previously been believed to represent early events in transformation, however our group and others have described such mutations in roughly one-third of cases of deep in…

PURPOSE: Deep infiltrating endometriosis (DIE) is defined as an endometriotic lesion penetrating to a depth of >5 mm and is associated with pelvic pain, but the underlying mechanisms are unclear. Our objective is to investigate whether plas…

INTRODUCTION: Pelvic pain and vulvar pain are common conditions in women. In this study, we sought to characterize the clinical picture of patients with concurrent pelvic pain and provoked vestibulodynia (PVD). AIM: To analyze the associat…

OBJECTIVE: To examine temporal trend in maternal mortality/severe morbidity associated with hospitalisation due to ectopic pregnancy. DESIGN: A population-based observational study. SETTING AND PARTICIPANTS: All women hospitalised for ect…

(Abstracted from Am J Obstet Gynecol 2018;218:114.e1–114.e12) Chronic pelvic pain (CPP) is a common clinical problem among women. Its etiology is complex and involves an interplay of gynecologic, urologic, gastrointestinal, musculoskeletal,…

INTRODUCTION: Deep dyspareunia occurs in half of women with endometriosis, a condition present in 10% of reproductive-age women and associated with negative effects on sexual quality of life (SQoL). However, women with endometriosis can hav…
