Lower urinary tract disorders in case of deep endometriosis are common (up to 50% of patients), although often masked by pelvic pain. They result from damage to the pelvic autonomic nervous system by direct infiltration of these structures …

INTRODUCTION: Endometriosis is a common disease that causes pain symptoms and/or infertility in women in their reproductive years. The disease is characterised by the presence of endometrium-like tissue - glands and stroma - outside the ute…

Endometriosis is considered as a tumor-like lesion under the World Health Organization (WHO) classification of ovarian tumors. Data from large cohort and case-control studies indicate that patients with a history of endometriosis have an in…

CONTEXT: Endometriosis is a common gynecologic condition characterized by an important inflammatory process mediated by the prostaglandin pathway. Oral contraceptives are the treatment of choice for symptomatic endometriotic women. However …

BACKGROUND: Uterine leiomyomas (fibroids) are the most common gynaecological benign tumors in premenopausal women. Evidences support the role of oxidative stress in the development of uterine leiomyoma. We have analysed oxidative stress mar…

OBJECTIVE: To determine the serum levels of interleukin (IL)-10 family ILs in women with ovarian endometriosis and investigate the correlation of these levels with disease activity. DESIGN: A case-control laboratory study. SETTING: Tertia…

STUDY QUESTION: Are interleukin-33 (IL-33) serum levels higher in women with uterine leiomyoma compared with controls without leiomyoma? SUMMARY ANSWER: Serum IL-33 is elevated in women with uterine leiomyoma and correlated with features o…

The surgical management of presumed benign ovarian tumors (PBOT) must ensure complete removal of the cyst, reduce the risk of recurrence (especially in case of endometrioma), prevent any risk of tumor dissemination, and must preserve health…

Infertility is a major, multifaceted issue worldwide whose prevalence is increasing in both high- and low-income countries. The reasons are numerous, and may differ among world regions, but lifestyle and nutritional factors, epidemic infect…

Endometrioma is a common ovarian cyst associated with pain and infertility, but its pathogenesis remains enigmatic. Demonstration of the subtelomeric location of hypermethylation in endometrioma has been reported by genome-wide profiling of…

Endometriosis is a chronic inflammatory disease affecting women's health. Pain and infertility are the major symptoms caused by a hormonal/immunological dysfunction, which causes an endometrial impairment. The same pathogenetic mechanisms a…

Endometriosis affects 6 to 10 % of all women of childbearing age. Intestinal involvement is defined by muscularis infiltration and has been estimated to occur in 8 % to 12 % of women with endometriosis. The most common sites are rectum, sig…

STUDY QUESTION: Are anti-Müllerian hormone (AMH) levels lower in women with endometriosis, notably those with endometriomas (OMAs) and deep infiltrating lesions, compared with controls without endometriosis? SUMMARY ANSWER: Endometriosis a…

Introduction: Endometriosis, histologically defined as the presence of endometrium-like tissue - glands and stroma - that develops outside of the uterine cavity, is still an enigmatic disease responsible for pelvic pain and infertility. The…

Cytokines, and specifically interleukin 6 (IL-6) and interleukin 8 (IL-8), have been associated with the pathogenesis of endometriosis. We studied serum concentrations of IL-6 and IL-8 in patients with deep infiltrating endometriosis (DIE) …

BACKGROUND: The objective of this study was to evaluate the significance of severe preoperative pain for patients presenting with ovarian endometrioma (OMA). METHODS: Three hundred consecutive patients with histologically proven OMA were e…

Recurrence of deep endometriosis remains a major issue in the management of endometriosis. The main cause for recurrence appears to be an incomplete excisional surgery. Therefore, the goal of the primary surgery should be the complete resec…

BACKGROUND: Interleukin 33 (IL-33) is a cytokine involved in fibrotic disorders. We have analyzed IL-33 levels in the sera and peritoneal fluids of women with various forms of endometriosis and investigated the correlation with disease acti…

OBJECTIVE: To investigate key genes expression of the sphingosine-1-phosphate pathway in endometriotic tissues. DESIGN: A case-control laboratory study. SETTING: Tertiary care university hospital. PATIENT(S): A total of 31 women, with (n…

OBJECTIVE: Experimental endotoxaemia induces subcutaneous adipose tissue inflammation and systemic insulin resistance in lean subjects. Glyceroneogenesis, by limiting free fatty acids (FFA) release from adipocytes, controls FFA homoeostasis…

BACKGROUND: An inverse association between BMI and endometriosis has been reported but remains controversial. We decided to evaluate the association between BMI and the different types of endometriosis, classified as superficial endometrios…

Glyceroneogenesis, a metabolic pathway that participates during lipolysis in the recycling of free fatty acids to triglycerides into adipocytes, contributes to the lipid-buffering function of adipose tissue. We investigated whether glyceron…

BACKGROUND/AIMS: Deep infiltrating endometriosis is a very painful condition and the mechanism of pain is still poorly understood. Pain and hyperalgesia can partly be explained by an increased number of nerve structures in the painful lesio…

Endometriosis causes pelvic pain and infertility. Infertility results from effects of endometriosis exerted in the pelvic cavity, in the ovaries and/or on the uterus. Medical treatment effective on pain and at preventing disease recurrence …

Endometriosis, a disease of young females that is possibly a devastating ailment requiring surgery, appears to be associated with certain features encountered in adolescence. First among these symptoms is the history of severe and lasting d…
