BACKGROUND: In the field of endometriosis, several classification, staging and reporting systems have been developed and published, but there are no data on the uptake of these systems in clinical practice. OBJECTIVES: The objective of the…

BACKGROUND: Different classification systems have been developed for endometriosis, using different definitions for the disease, the different subtypes, symptoms and treatments. In addition, an International Glossary on Infertility and Fert…

BACKGROUND: In the field of endometriosis, several classification, staging and reporting systems have been developed. However, endometriosis classification, staging and reporting systems that have been published and validated for use in cli…

BACKGROUND: Endometriosis is typically regarded as a premenopausal disease, resolving after natural or iatrogenic menopause due to declining oestrogen levels. Nonetheless, case reports over the years have highlighted the incidence of recurr…

Endometriosis is a gynecologic disease affecting up to 10% of the women and a major cause of pain and infertility. It is characterized by the implantation of functional endometrial tissue at ectopic positions generally within the peritoneum…

Endometriosis is a common, chronic gynaecological disease affecting up to 10% of women in their reproductive years. Its aetiology still remains unclear, but evidence indicates genetic factors play a role. We previously identified a region o…

BACKGROUND: Endometriosis is prevalent and women need high-quality care, which should be patient-centered. This study aimed to develop a valid and reliable patient-centeredness questionnaire, based on a defined concept of patient-centered e…

OBJECTIVE: To investigate whether the eNOS gene influences the risk of developing endometriosis in south Indian women. STUDY DESIGN: The single nucleotide polymorphism, Glu298Asp, in exon7 of the eNOS gene was tested for association in a c…

The relationship between endometriosis and polymorphisms in the N-acetyl transferase 2 (NAT 2) gene was investigated in a UK population, as this gene has been previously implicated in the aetiology of the disease. Point mutations in the gen…

OBJECTIVES: This study was undertaken to investigate the overlap between chronic pelvic pain, dysmenorrhea, dyspareunia, irritable bowel syndrome, and genitourinary symptoms in the community and also to examine associated investigations and…

BACKGROUND: Chronic pelvic pain has often been described as a major women's health issue, but no information exists on the extent of the problem in the United Kingdom. AIM: To investigate the community prevalence of chronic pelvic pain and…

Family studies have long suggested a role for genetic factors in the aetiology of endometriosis. The influence of genes on disease development has mainly been researched independently of environmental factors, yet their interaction must pla…

OBJECTIVES: To describe duration of symptoms and patterns of diagnosis and referral in women with chronic pelvic pain. DESIGN: Retrospective cohort analysis of the MediPlus UK Primary Care Database. SETTING: One hundred and thirty-six gen…

OBJECTIVES: To estimate the prevalence and incidence in primary care of chronic pelvic pain in women in the UK. DESIGN: Cross-sectional analysis of MediPlus UK Primary Care Database. SETTING: One hundred and thirty-six general practices i…

OBJECTIVE: To obtain a prevalence estimate for chronic pelvic pain in women in the United Kingdom by analysing published data. DESIGN: Systematic review of published papers. SETTING: The general population or hospitals in the United Kingd…
