Abstract
Serous, endometrioid, clear cell and mucinous histotypes are the most common epithelial ovarian cancer. Most serous cancers appear to originate from precursor lesions at the fimbriated tubal end, whereas most endometrioid and clear cell cancers seem to derive from atypical endometriosis. Data regarding hormonal factors and associated gynaecologic conditions were critically analysed with the objective of defining a carcinogenic model for sporadic epithelial ovarian cancer complying with epidemiologic and pathologic findings. Oral contraceptives and tubal ligation substantially reduce the risk of serous, endometrioid and clear cell subgroups, but have no significant effect on mucinous tumours, which probably follow a different oncogenic pathway. We hypothesize that serous, endometrioid and clear cell cancers share a common pathogenic mechanism, i.e. iron-induced oxidative stress derived from retrograde menstruation. Fimbriae floating in bloody peritoneal fluid are exposed to the action of catalytic iron and to the genotoxic effect of reactive oxygen species, generated from haemolysis of erythrocytes by pelvic macrophages. This would explain the distal site of tubal intraepithelial neoplasia. Collection of blood inside endometriomas would lead to the same type of genotoxic insult on gonadal endometrial implants. This would explain why endometriosis-associated cancers develop much more frequently in the ovary than at extragonadal sites. In women not seeking conception, bilateral salpingectomy could be advised whenever planning surgery for independent indications, thus possibly reducing cancer risk, while preserving ovarian function. The use of oral contraceptives should be favoured for prolonged periods of time, especially in women with endometriosis, a population at doubled risk of gonadal malignancy.

Abstract
OBJECTIVE To report a case of uncommon endometriosis located in the Nuck's duct and its laparoscopic resolution. DESIGN Case report. SETTING Gynecologic department at 12 de Octubre University Hospital, Madrid. PATIENT(S) A 35-year-old woman, gravida 1 para 1, presented with an inguinal right mass. She had a right nephrectomy because of acute pyelonephritis. Computed tomography showed a cystic lesion that was suggestive of a Nuck's duct cyst. Fine-needle aspiration cytology was performed, and endometriosis was determined. INTERVENTION(S) Cyst removal and closure of the internal inguinal ring's defect by the laparoscopic approach. MAIN OUTCOME MEASURE(S) Disease free. RESULT(S) The intervention was successfully performed by laparoscopic approach. The postoperative evolution was good, and the patient was discharged 2 days after surgery. CONCLUSION(S) Inguinal or Nuck's duct are both uncommon locations for endometriosis; therefore, it is difficult to suspect in patients without a surgical history. Once identified, the treatment involves removal of the endometrioma and repair of the internal inguinal ring. A laparoscopic approach should be considered when possible.

Abstract
OBJECTIVE To investigate the effect of two laparoscopic techniques for treatment of ovarian endometriomas on recurrence rate. DESIGN Prospective randomized clinical trial. SETTING University teaching hospital. PATIENT(S) Ninety women with ovarian endometriomas. INTERVENTION(S) Patients were randomly selected to undergo either laparoscopic cystectomy (group 1) or laser vaporization (group 2) of ovarian endometrioma. MAIN OUTCOME MEASURE(S) Recurrence, evaluated by ultrasound scan examination, was assessed at 12 and 60 months of follow-up. RESULT(S) Endometrioma recurrence rate was higher, though not significantly different, in group 2 at 60 months of follow-up. Nevertheless, at 12 months of follow-up recurrences were statistically higher in group 2. CONCLUSION(S) The comparison between laparoscopic laser ablation and laparoscopic cystectomy for ovarian endometriomas after long-term follow-up showed earlier recurrences and a higher recurrence rate in the laser group, although at 5 years of follow-up there were no statistically significant differences.

Abstract
The objective of this paper was to investigate the effects of a Chinese Materia Medica variant -Fubao Danggui Jiao (FDJ)-on experimental endometriosis. An endometriosis model was created by virtue of auto-transplantation of endometrial tissue onto rats' abdominal walls. The implants were allowed to grow for 30 days until the successful completion of the model. After that, forty endometriotic rats were randomly divided into four study groups and given different treatments: (1) negative control group (water, 2ml/kg, per os); (2) FDJ-A group (FDJ, 2ml/kg, per os); (3) FDJ-B group (FDJ, 4ml/kg, per os); (4) Danazol group (70mg/kg, per os). After 30 days with treatments, the volumes of endometriotic implants in each rat were measured. The implants and normal uterine horns were removed for routine histological examination. FDJ caused significant decreases in volumes of the surviving endometriotic implants, with two different doses having statistically equivalent effects. Upon histological examination, FDJ was observed to cause regression of epithelium and stroma of endometriotic implants. FDJ had revealed promising therapeutic effects on endometriosis.

Abstract
BACKGROUND In a university hospital setting, a 25-year-old woman presented with large vaginal and cervical polyps. Past medical history was significant for stage IV endometriosis. Polypectomy was performed and the polyps were histologically consistent with endometriosis. Gene expression was compared with control vaginal tissue to assess if the altered gene expression profile was similar to peritoneal endometriosis. METHODS AND RESULTS Using quantitative reverse transcription, real-time PCR, estrogen receptor-β expression was found to be upregulated 10-fold while estrogen receptor-α expression was downregulated 5-fold in the vaginal polyp relative to control vaginal tissue. The estrogen-synthesizing enzyme aromatase was upregulated 8-fold and 3β-hydroxysteroid dehydrogenase was upregulated 400-fold in the polyp. Immunohistochemical staining revealed altered cell type localization for progesterone receptor in the polyp and increased cell proliferation in polyp stromal cells relative to control. CONCLUSIONS Increased proliferation in the vaginal polypoid endometriotic tissue may be due to increased local estrogen production. The altered gene expression profile was very similar to the altered gene expression profile seen in peritoneal endometriosis.

Abstract
A detailed picture of the prevalence and distribution of abdomino-pelvic endometriosis in more that 1,500 cases of endometriosis stage IV is presented. A great prevalence of endometriotic localizations in the posterior pelvic compartment compared to the other quadrants with more frequently observed lesions on the left part of the pelvis supports the menstrual reflux theory. The extent of anatomical sites suggests the opportunity to plan a proper preoperative instrumental study for patients with clinical suspect of severe endometriosis possibly to set a multidisciplinary clinical or surgical management.

Abstract
AIM To confirm the hypothesis of the presence of a possible endometriosis inducing factor(s) (EIF) in the blood of women with endometriosis. PATIENTS AND METHODS Forty infertile women were studied. The study group compromised of fifteen women of each three different degrees of endometriosis and fifteen women without endometriosis as a control group. Stem cells are characterized by being spindle shaped and proliferate in appropriate culture indefinitely. The women sera were co-cultured with mesenchymal stem cells (MSCs) which were followed up weekly to look for morphological changes and to detect Annexin 1 marker and ß-actin gene by reverse transcriptase polymerase chain reaction. RESULTS MSCs cultured with sera of cases with, mild, moderate and severe endometriosis, showed morphological changes to be columnar and cuboidal shaped cells -resembling endometrial cells and glands- by the 4th week in 60%, 60% & 100% respectively. These cells were detected from as early as the first week in women with moderate and severe types (20% for each group). The percentage of the change into endometrial like cells increased among the three groups where it was 30±25.8%, 45±29.9% and 75±37.9% respectively. Moreover, increasing number of endometrial like cells are detected weekly, the more severe the disease is. None of the cultures of serum of the control group had made such changes all over the study. Furthermore, with more differentiation there was a considerable decrease in number of stem cells. These differentiated cells expressed the Annexin-1 marker. CONCLUSION It was evident that serum of women with endometriosis posses a factor(s) that enables the MSCs to be transformed into endometrial like cells and glands in vitro. This finding supports a new theory for the etiology of endometriosis. This observation may have a tremendous effect on the therapeutic implications of this debilitating condition.

Abstract
Endometriosis-associated infertility has a multifactorial etiology. We tested the hypothesis that the endometrial response to the early embryonic signal, human chorionic gonadotropin (hCG), alters over time in a nonhuman primate model of endometriosis. Animals with experimental or spontaneous endometriosis were treated with hCG (30 IU/d), from d 6 after ovulation for 5 d, via an oviductal cannula. Microarray analysis of endometrial transcripts from baboons treated with hCG at 3 and 6 months of disease (n=6) identified 22 and 165 genes, respectively, whose levels differed more than 2-fold compared with disease-free (DF) animals treated with hCG (P<0.01). Quantitative RT-PCR confirmed abnormal responses of known hCG-regulated genes. APOA1, SFRP4, and PAPPA, which are normally down-regulated by hCG were up-regulated by hCG in animals with endometriosis. In contrast, the ability of hCG to induce SERPINA3 was lost. Immunohistochemistry demonstrated dysregulation of C3 and superoxide dismutase 2 proteins. We demonstrate that this abnormal response to hCG persists for up to 15 months after disease induction and that the nature of the abnormal response changes as the disease progresses. Immunohistochemistry showed that this aberrant gene expression was not a consequence of altered LH/choriogonadotropin receptor distribution in the endometrium of animals with endometriosis. We have shown that endometriosis induces complex changes in the response of eutopic endometrium to hCG, which may prevent the acquisition of the full endometrial molecular repertoire necessary for decidualization and tolerance of the fetal allograft. This may in part explain endometriosis-associated implantation failure.

Abstract
Diet plausibly has a role in the aetiology of endometriosis through effects on steroid hormone levels; however, few published studies have examined the diet and endometriosis risk. We evaluated dietary risk factors for endometriosis in a population-based case-control study. Cases were 284 Group Health (GH) enrollees aged 18-49 years with newly diagnosed, surgically confirmed endometriosis between 1996 and 2001. Controls were 660 randomly selected age-matched female GH enrollees without a history of endometriosis. Nutrients and selected food groups were assessed using the Women's Health Initiative FFQ. OR of endometriosis risk associated with dietary exposures were estimated using unconditional logistic regression and adjusted for identified covariates. Increased total fat consumption was associated with decreased endometriosis risk (fourth quartile v. lowest: OR 0·5, 95% CI 0·2, 1·0, P-trend = 0·12). Increased β-carotene consumption and servings/d of fruit were associated with increased risk (β-carotene third quartile v. lowest: OR 1·7, 95% CI 1·1, 2·6; fourth quartile v. lowest: OR 1·6, 95% CI 1·0, 2·5, P-trend 0·16; fruit >2 servings/d v. < 1: OR 1·5, 95% CI 1·0, 2·3, P-trend = 0·04). We also found a suggestion of decreased endometriosis risk associated with the consumption of dairy products (2 servings/d v. ≤ 1: OR 0·6, >2 servings/d v. ≤ 1: OR 0·7), but this association was not statistically significant for the highest tertile. The present study suggests that specific dietary components may be associated with endometriosis risk.

Abstract
Endometriosis is the third leading cause of gynecologic hospitalization in the United States. This disease impacts both a woman's physical and mental well being. This impact is often compounded by the frequent delay from the onset of symptoms to a confirmed diagnosis, which may average 6 years or more. The precise incidence and prevalence of endometriosis remains elusive for a multitude of reasons, and their measurement remains difficult to accurately assess. None the less, there are many unique and interesting components to the disease which arise when population-based analyses are performed. The goal of this paper is to investigate and summarize the existing epidemiologic parameters, primarily risk factors, associated with endometriosis.

Abstract
BACKGROUND Combined oral contraceptives (OCs) inhibit ovulation, substantially reduce the volume of menstrual flow and may hypothetically interfere with implantation of refluxed endometrial cells. The aim of this review is to establish if OC use influences the risk of endometriosis. METHODS We performed a MEDLINE search to identify all studies published in the last four decades (January 1970 to January 2010) in the English language on the relationship between OC exposure and risk of endometriosis. Two authors abstracted data on standardized forms. RESULTS We identified 608 potentially relevant studies and 18 studies (6 cross-sectional, 7 case-control and 5 cohort) were selected. Pooling of the results derived from all the included reports independently from study design, yielded a common relative risk of 0.63 [95% confidence interval (CI), 0.47-0.85] for current OC users, 1.21 (95% CI, 0.94-1.56) for past users and 1.19 (95% CI, 0.89-1.60) for ever users. Methodological drawbacks, such as uncertain temporal relationship between exposure and outcome in cross-sectional studies and suboptimal selection of controls in case-control studies, limit the quality of the available evidence. CONCLUSIONS The risk of endometriosis appears reduced during OC use. However, it is not possible to exclude the possibility that the apparent protective effect of OC against endometriosis is the result of postponement of surgical evaluation due to temporary suppression of pain symptoms. Confounding by selection and indication biases may explain the trend towards an increase in risk of endometriosis observed after discontinuation, but further clarification is needed. To date, the hypothesis of recommending OCs for primary prevention of endometriosis does not seem sufficiently substantiated.

Abstract
OBJECTIVE To investigate the association between self-reported endometriosis and the putative functional promoter +331C/T single nucleotide polymorphism and the PROGINS allele. DESIGN Control subjects from ovarian cancer case-control studies participating in the international Ovarian Cancer Association Consortium. The majority of controls are drawn from population-based studies. SETTING An international ovarian cancer consortium including studies from Australia, Europe, and the United States. PATIENT(S) Five thousand eight hundred twelve white female controls, of whom 348 had endometriosis, from eight ovarian cancer case-control studies. INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) Genotypes for the +331C/T single nucleotide polymorphism and PROGINS allele and a history of endometriosis. RESULT(S) The occurrence of endometriosis was reduced in women carrying one or more copies of the +331 T allele (odds ratio=0.65; 95% confidence interval: 0.43-0.98), whereas there was no association between the PROGINS allele and endometriosis (odds ratio=0.94, 95% confidence interval 0.76-1.16). CONCLUSION(S) Additional studies of the +331C/T variant are warranted given the current finding and the equivocal results of previous studies. The +331 T allele has been shown to result in a reduced progesterone (P) receptor A to P receptor B ratio, and if the observed association with endometriosis is confirmed it would suggest that this ratio is important for this disease.

Abstract
We report an unusual case of a retroperitoneal cystic adenocarcinoma arising in a focus of extra-ovarian retroperitoneal endometriosis. The lesion was completely excised using a transperitoneal laparoscopic approach without the need for any adjuvant chemotherapy or radiation therapy. The patient remains clinically well with no evidence of recurrent or metastatic disease after 3 years of follow-up. To our knowledge, this is the first reported case of this type of rare extra-gonadal endometriosis-associated neoplasm with successful laparoscopic excision.

Hum Reprod 2010; 25:1241-50. [PMID: 20176595 PMCID: PMC2902841 DOI: 10.1093/humrep/deq032] [Citation(s) in RCA: 30] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/11/2008] [Revised: 01/08/2010] [Accepted: 01/25/2010] [Indexed: 12/11/2022] Open
Abstract
BACKGROUND Evidence suggests that eutopic endometrium from women with endometriosis (US-E) has intrinsic functional anomalies compared with women without endometriosis (US-C). We hypothesized that differences in endometrial haptoglobin (eHp) mRNA and protein levels exist between eutopic endometrium from US-E and US-C and that inflammatory mediators may be involved. METHODS Endometrial stromal cells and tissue explants from US-E (n = 18) and US-C (n = 18) were cultured (24 h/48 h for cells/explants) with interleukin (IL)-1alpha, -1beta, -6, -8 or tumor necrosis factor-alpha (TNF-alpha) at 0-100 ng/ml. eHp protein in media and mRNA levels were quantified by enzyme-linked immunosorbent assay and quantitative PCR. RESULTS In eutopic endometrial stromal cells from US-E, IL-1beta, IL-6 and TNF-alpha (10 ng/ml) increased eHp mRNA levels (P = 0.002, P < 0.001 and P < 0.001, respectively) and eHp protein (P = 0.023, 0.031 and 0.006, respectively) versus control. In endometrial tissues from US-E, IL-1beta, IL-6 and TNF-alpha increased eHp mRNA (P < 0.001, P = 0.017 and P < 0.001, respectively) and eHp protein (P < 0.001, P = 0.007 and 0.039, respectively) versus control. IL-1alpha and IL-8 had small or no effects on isolated endometrial cells or tissues. In US-C, IL-1beta, IL-8 and TNF-alpha each reduced eHp mRNA in endometrial stromal cells (all P < 0.001) versus control; IL-1alpha and IL-6 had no effect. eHp mRNA increased in endometrial tissues from US-C in response to IL-1beta (P = 0.008), IL-6 (P = 0.015) and TNF-alpha (P = 0.031) versus control; IL-1alpha or IL-8 had no effect. CONCLUSIONS Endometrium from US-E differentially responds to specific inflammatory cytokines by production of eHp. We propose that up-regulation of endometrial eHp by inflammatory mediators disrupts normal endometrial function and may facilitate the pathogenesis of endometriosis.

Reprod Biomed Online 2010; 21:259-65. [PMID: 20541975 DOI: 10.1016/j.rbmo.2010.04.018] [Citation(s) in RCA: 65] [Impact Index Per Article: 4.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2009] [Revised: 10/09/2009] [Accepted: 03/10/2010] [Indexed: 10/19/2022]
Abstract
Prevention of the recurrence of post-operative endometriosis is crucial for future fertility. The incidence of disease relapse can be influenced by major demographic changes and by the use of long-term adjuvant medical treatment. Decrease in age at menarche, number of pregnancies and duration of breastfeeding and increase in age at first birth all lead to an increase in the overall number of ovulations and menstruations a woman has within a reproductive lifespan. These changes impact during the decade at highest risk for endometriosis, i.e. between 25 and 35 years of age, and may substantially expand the hiatus between first-line surgical treatment and conception attempt. Several lines of evidence suggest that ovulation inhibition reduces the risk of endometriosis recurrence. After pooling the results of a cohort and a randomized controlled trial on long-term post-operative oral contraceptive use, a recurrent endometrioma developed in 26/250 regular users (10%; 95% CI 7-15%) compared with 46/115 never users (40%; 95% CI 31-50%), with a common OR of 0.16 (95% CI 0.04-0.65). After first-line surgery for endometriosis, women should be invited to seek conception as soon as possible. Alternatively, oral contraceptive use until pregnancy is desired should be considered.

Abstract
Protein kinase B (PKB/Akt), a serine/threonine kinase, regulates the function of many cellular proteins involved in apoptosis and proliferation. It was postulated that there is a higher Akt activity in endometriosis compared with normal endometrium, and that oestrogen may be one of the factors responsible for the high Akt activation in endometriotic cells. Phospho-Akt (pAkt) concentrations in normal, eutopic and ectopic endometrial tissues were compared by immunohistochemistry, and a higher pAkt immunoreactivity was revealed in eutopic and ectopic endometrium compared with normal endometrium, in vivo. Higher Akt phosphorylation in stromal cells from eutopic endometrium was observed, when compared with normal, in vitro (P < 0.05). Akt phosphorylation was rapidly (2-10 min) stimulated when endometrial stromal cells from normal and endometriosis patients were treated with 17 beta-oestradiol. In endometrial stromal cells from the endometriosis group, ICI 182,780 (ICI, a specific oestrogen receptor antagonist) failed to antagonize the effect of oestradiol when combined with oestradiol, and revealed a stimulatory effect on Akt phosphorylation when given alone (P < 0.05). In conclusion, since Akt affects cell survival, it is suggested that increased Akt phosphorylation may be related to the altered apoptosis/proliferation harmony in endometriosis, and therefore Akt may play a critical role in the pathogenesis of endometriosis.

Abstract
Endometriosis is a common disease, but ureteral involvement is rare. The symptoms and signs of ureteral endometriosis mimic those of ureteral malignancy. This case report describes a woman who presented with chronic back pain for 5 years. Imaging studies showed a right small contracted kidney with hydronephrosis and a bladder tumor. Endometriosis of the right lower ureter was ultimately diagnosed. The patient was healthy without recurrence during follow-up. It is difficult to differentiate between ureteral endometriosis and malignancy; in fact, renal loss may occur before diagnosis. Ureteral endometriosis should be considered for women with ureteral obstruction manifesting as chronic backache.

Abstract
Phthalates may act as an estrogen and are a potential risk factor for estrogen-related diseases such as endometriosis. We assessed the association between phthalate exposure and endometriosis in 166 consecutive women who presented at a university hospital for consultation regarding infertility. The subjects were interviewed and provided a urine specimen prior to a laparoscopic diagnosis of endometriosis. They were then categorized by the severity of endometriosis as controls (stages 0-I) and cases (stages II-IV). Urinary concentrations of the phthalate metabolites monoethyl phthalate, mono-n-butyl phthalate, monobenzyl phthalate, mono(2-ethylhexyl) phthalate (MEHP), mono(2-ethyl-5-oxohexyl) phthalate, and mono(2-ethyl-5-hydroxyhexyl) phthalate were measured in 57 cases and 80 controls using high-performance liquid chromatography isotope-dilution tandem mass spectrometry. Adjusted odds ratios for endometriosis in relation to dichotomized individual phthalate metabolites (standardized for creatinine) were calculated. No significant association between endometriosis and any urinary creatinine-adjusted phthalate monoester was seen. Adjusted odds ratio (95% confidence interval) for higher dichotomized MEHP by endometriosis was 1.57 (0.74-3.30). No monotonic trend was seen in urinary creatinine-adjusted concentration of phthalate metabolites by endometriosis stage (p=0.23-0.90). Our results do not support the hypothesis that higher urinary concentrations of phthalate metabolites are associated with the risk of endometriosis in infertile Japanese women.

Abstract
STUDY OBJECTIVE We aim to describe the clinical characteristics and the principles of combined laparoscopic and thoracoscopic management of women with diaphragmatic endometriosis at our institution. DESIGN Case series (Canadian Task Force Classification II2). SETTING Tertiary care referral center. PATIENTS Four women with diaphragmatic endometriosis. INTERVENTIONS Laparoscopy and thoracoscopy. MEASUREMENTS We retrospectively reviewed the charts of 4 consecutive women with diaphragmatic endometriosis who underwent laparoscopy and thoracoscopy from June 2008 through September 2008. MAIN RESULTS Four patients underwent a combination of laparoscopy for treatment of abdominopelvic endometriosis and thoracoscopy for treatment of diaphragmatic endometriosis. All patients had a history of chest pain. Three had a history of pelvic pain. Two had a history of catamenial hemothorax or pneumothorax. Two had been previously diagnosed with endometriosis, and three had a history of hormonal pharmacotherapy. All underwent laparoscopy and thoracoscopy without complications. All had uneventful recoveries. At nine-month follow-up, all patients were free of chest pain, and one patient had recurring pelvic pain. CONCLUSIONS To the best of our knowledge, this constitutes the only reported series of patients with endometriosis who underwent a procedure systematically combining both laparoscopy and thoracoscopy for treatment of abdominopelvic and thoracic disease. It confirms that combined laparoscopic and thoracoscopic diagnosis and management of diaphragmatic endometriosis is reasonable. The inferior aspect of the diaphragm should be evaluated in all patients undergoing laparoscopy for endometriosis. Concomitant thoracoscopy should be considered for all patients with history of catamenial hemopneumothorax, cyclic chest or shoulder pain, or cyclic dyspnea. The aim of treatment should be to remove endometriotic lesions, to provide symptomatic relief, and to avoid recurrence. The use of these minimally invasive techniques may reduce the need for laparotomy or thoracotomy in affected patients.

Abstract
Here, we report regarding the health status and medical support for patients suffering from endometrioisis in South Tyrol, which is a politically autonomous province in the north of Italy containing three different ethnic groups. The health service is administered largely by the autonomous regional government. Because of the establishment of a centre for reproductive medicine and the introduction of laparoscopy as a prime surgery method, the gynaecological department of the hospital in Bruneck developed into a reference centre for diagnosis and surgical treatment for endometriosis. The planned future social, health care and insurance developments on local and national level regarding this illness will be discussed.

Abstract
INTRODUCTION Dysmenorrhoea is the major symptom in women with endometriosis. Recently, pain modulation through Neurokinin-1-receptor (NK1R) pathways have been investigated in neuropathic pain patients. Aim of this study was, therefore, to examine the effect of a single nucleotide polymorphism (SNP) of the NK1R gene on the susceptibility for endometriosis and the disease free survival (DFS) after surgery for endometriosis. MATERIAL AND METHODS A case-control study was conducted and germline DNA was isolated. Patients were followed up for a recurrence of the disease up to 4 years. Case-control analyses were performed for parameters of the medical history and the genotype of the NK1R-SNP rs881. Furthermore, DFS probabilities were calculated. RESULTS Concerning the DFS preoperative pain levels and the NK1R genotype were independent predictors for a recurrence with hazard ratios of 2.55 (95% CI: 1.32-4.95) for patients with a high preoperative pain level and 0.44 for patients with a heterozygous or homozygous variant genotype in rs881 (95% CI: 0.21-0.88). CONCLUSION The polymorphism rs811 seems to be associated with a lower recurrence risk in endometriosis patients. Thus, there might be a clinical relevant role of the NK1 pathway in the pain perception of endometriosis patients.

Abstract
BACKGROUND this study aims to evaluate the effectiveness and safety of laparoscopic conservative management of ureteral endometriosis. METHODS Eighty cases of histologically confirmed endometriosis affecting the ureter, 10 of which with bladder involvement were prospectively studied. In detail, patients were 13 women with ureteral stenosis (7 with hydronephrosis), 32 with circular lesions totally encasing the ureter, and 35 with endometriotic foci on the ureteral wall, but not completely encasing it. They were submitted to laparoscopic ureterolysis with or without partial cystectomy, ureteroneocistostomy. The rate of surgical complications, the recurrence rate, the patients' satisfaction rate was assessed during 22 months (median) follow-up. RESULTS Laparoscopic ureterolysis was employed for all patients and set free the ureter from the disease in 95% of cases, whereas ureteroneocystostomy was necessary for 4 patients showing severe stenosis with hydronephrosis, among which 2 had intrinsic endometriosis of the ureteral muscularis. Three post-surgery ureteral fistulae occurred in cases with ureteral involvement longer than 4 cm: two cases were successfully treated placing double J catheter, the third needed ureteroneocistostomy. During follow-up, ureteral endometriosis recurred in 2 patients who consequently underwent ureteroneocystostomy. Most patients expressed high satisfaction rate throughout the whole follow-up period. CONCLUSION laparoscopic ureterolysis is effective and well tolerated in most cases of ureteral endometriosis. Ureteroneocystostomy is a better strategy for patients with extended (more than 4 cm) ureteral involvement or with severe stenosis with or without hydronephrosis.

Abstract
BACKGROUND Endometriosis usually affects women in their reproductive years. Most commonly, the pelvic organs are involved. Involvement of the chest wall after hysterectomy is rare. The incidence of malignant transformation is less than 1% for ovarian endometriosis, but is unknown for extraovarian endometriosis. CASE A 47-year-old woman who had undergone hysterectomy and bilateral salpingo-oophorectomy for endometriosis presented four years after surgery with a well-differentiated endometrioid adenocarcinoma arising in the background of endometriosis in the right chest wall. The tumour was resected, and the patient received six courses of adjuvant chemotherapy. CONCLUSION Women with endometriosis-associated cancer require individualized management options, depending upon the histopathology and stage of the cancer.

Abstract
AIM To investigate the association of CYP2C19 genotypes with endometriosis. METHODS The study included 100 women who underwent laparotomy or laparoscopy: 50 patients with endometriosis diagnosed with surgery and histopathology, and 50 control subjects who had no evidence of endometriosis during exploratory laparotomy or laparoscopy. Genomic DNA of subjects was extracted from the whole blood using High Pure PCR template preparation kit. Genotyping of CYP2C19 polymorphisms were detected by using a LightCycler CYP2C19 mutation detection kit in a real-time PCR, and were compared between the two groups. RESULTS Logistic regression analyses showed that the CYP2C19*2 heterozygote genotype was associated with a significantly increased risk of endometriosis. The odds ratio of endometriosis for the CYP2C19*2 heterozygote genotype was 3.165 (p = 0.023) compared with the control group. CYP2C19*3 genotype was detected as wild in all subjects in the endometriosis and control groups. CONCLUSION Our results suggest that CYP2C19*2 heterozygote genotype has higher risk of developing endometriosis. Therefore, CYP2C19*2 allele gene polymorphisms may be associated with genetic susceptibility of endometriosis.

Abstract
The objective of this prospective study was to assess the safety and short-term outcome of the Helica Thermal Coagulator in the laparoscopic treatment of early stage endometriosis. Two hundred and fifty consecutive women with chronic pelvic pain and stage I and II endometriosis (r-AFS classification) were treated laparoscopically with the Helica Thermal Coagulator. No bladder, ureteric or bowel injuries occurred. None of the procedures was converted to laparotomy and there were no major peri-operative complications. The only complication was a vaginal perforation during dissection of the cul-de-sac in a patient with a vaginal vault endometriotic nodule. We conclude that the Helica Thermal Coagulator is a safe alternative for the treatment of mild to moderate endometriosis. Long-term efficacy studies are required to better assess the role of the device in laparoscopic management of endometriosis.

Abstract
BACKGROUND Immune alterations may be involved in the pathogenesis and progression of endometriosis. Dendritic cells (DCs) are potent antigen presenting cells that are highly involved in the initiation of the immune response. The aim of this study was to investigate DC populations in the eutopic and ectopic endometrium of women with endometriosis compared with controls. METHODS Hysterectomy samples were obtained from premenopausal women with (n = 33) and without (n = 28) endometriosis. In addition, paired peritoneal endometriotic lesions and uterine curettings were collected from 32 women with endometriosis. Specimen sections were stained immunohistochemically using antibodies for monoclonal mouse antibodies directed against human CD1a and CD83, which are specific for immature and mature DCs, respectively. RESULTS The mean density of endometrial CD1a+ DCs in the basal layer was significantly increased in women with endometriosis compared with controls during the proliferative phase only (P = 0.001). There was a highly significant decrease in the density of endometrial CD83+ DCs in women with endometriosis compared with controls in both layers of the endometrium across all phases of the menstrual cycle (P = 0.001). The density of CD1a+ DCs was significantly increased in peritoneal endometriotic lesions (P = 0.003) and in the surrounding peritoneum (P = 0.001) compared with paired uterine curettings and peritoneum distant from the lesion. CONCLUSIONS Both CD1a+ and CD83+ DC populations were altered in the eutopic and ectopic endometrium of women with endometriosis compared with controls. Alterations in these cells, which play a crucial role in the coordination of the immune response, may be involved in pain generation and the pathogenesis of endometriosis.

Abstract
OBJECTIVE The main objective was to examine the association between simple hysterectomy (without bilateral oophorectomy) and breast cancer risk. Because hysterectomy prevalence varies by ethnicity, the secondary objective was to examine whether inclusion of women with hysterectomies affects the estimates of breast cancer risk by ethnicity. METHODS The Multiethnic Cohort study was assembled between 1993 and 1996 and included 68,065 women from Hawaii and Los Angeles, aged 45-75 years, without any missing information or bilateral oophorectomy. Hysterectomy status was self-reported. After 7.7 years median follow-up, 1,862 cases of invasive breast cancer were identified. Proportional hazards models were used to estimate relative risks (RR) while controlling for known risk factors. RESULTS Prevalence of simple hysterectomy varied from 12% to 29% among the ethnic groups (White, African American, Native Hawaiian, Japanese American, and Latina). Overall, hysterectomy was not associated with breast cancer risk (RR = 0.98). Although the RRs were nonsignificantly elevated by 15% in White women and nonsignificantly reduced by 15% in Latinas of non-US origin, the variation by ethnicity was not significant (p(interaction) = 0.48). The breast cancer risk associated with ethnicity was very similar when estimated with and without women with hysterectomies. CONCLUSIONS This study suggests that simple hysterectomy status does not alter breast cancer risk. Therefore, inclusion of women with simple hysterectomies does not substantially change estimated risk of breast cancer by ethnicity.

Abstract
OBJECTIVE To evaluate the possible role of endocrine-disrupting compounds (EDCs) on female reproductive disorders emphasizing developmental plasticity and the complexity of endocrine-dependent ontogeny of reproductive organs. Declining conception rates and the high incidence of female reproductive disruptions warrant evaluation of the impact of EDCs on female reproductive health. DESIGN Publications related to the contribution of EDCs to disorders of the ovary (aneuploidy, polycystic ovary syndrome, and altered cyclicity), uterus (endometriosis, uterine fibroids, fetal growth restriction, and pregnancy loss), breast (breast cancer, reduced duration of lactation), and pubertal timing were identified, reviewed, and summarized at a workshop. CONCLUSION(S) The data reviewed illustrate that EDCs contribute to numerous human female reproductive disorders and emphasize the sensitivity of early life-stage exposures. Many research gaps are identified that limit full understanding of the contribution of EDCs to female reproductive problems. Moreover, there is an urgent need to reduce the incidence of these reproductive disorders, which can be addressed by correlative studies on early life exposure and adult reproductive dysfunction together with tools to assess the specific exposures and methods to block their effects. This review of the EDC literature as it relates to female health provides an important platform on which women's health can be improved.

Abstract
Endometriosis is an often painful medical condition in which, in response to hormones associated with the menstrual cycle, the uterine lining grows in the peritoneum and other organs, bleeding into the surrounding organs and tissues. Diagnosis is not always straightforward, and women and health professionals alike may have difficulties recognizing period pain as a sign of anomaly, considering it instead as an inevitable part of menstruation. This article describes the illness narratives of Australian women with endometriosis, drawing on data collected during a study conducted in Victoria in 2004-5. Thirty women (aged 20-78 years) from various socio-demographic backgrounds participated in in-depth interviews. We explore the influence of socio-demographic background and social and family norms on women's illness narratives of endurance and contest. Narratives of endurance are characterized by the normalization of period pain by young women, their families and health professionals, and, with diagnosis, long-term exposure to biomedical treatments. In contrast, narratives of contest are dominated by how women's subjective experience is challenged by doctors, their requirements for a patient-centered approach, and their desire to have access to complementary treatments.

Abstract
OBJECTIVE To determine the value of patient-reported symptoms in diagnosing endometriosis. DESIGN A national case-control study. SETTING Data from the UK General Practice Research Database for years 1992-2001. SAMPLE A total of 5540 women aged 15-55 years, diagnosed with endometriosis, each matched to four controls without endometriosis. METHODS Data were analysed to determine whether specific symptoms were highly indicative of endometriosis. Odds ratios for these symptoms were derived by conditional logistic regression analysis. MAIN OUTCOME MEASURES Symptoms associated with endometriosis. RESULTS The prevalence of diagnosed endometriosis was 1.5%. A greater proportion of women with endometriosis had abdominopelvic pain, dysmenorrhoea or menorrhagia (73%) compared with controls (20%). Compared with controls, women with endometriosis had increased risks of abdominopelvic pain (OR 5.2 [95% CI: 4.7-5.7]), dysmenorrhoea (OR 8.1 [95% CI: 7.2-9.3]), menorrhagia (OR 4.0 [95% CI: 3.5-4.5]), subfertility (OR 8.2 [95% CI: 6.9-9.9]), dyspareunia and/or postcoital bleeding (OR 6.8 [95% CI: 5.7-8.2]), and ovarian cysts (OR 7.3 [95% CI: 5.7-9.4]), and of being diagnosed with irritable bowel syndrome (IBS) (OR 1.6 [95% CI: 1.3-1.8]) or pelvic inflammatory disease (OR 3.0 [95% CI: 2.5-3.6]). Women with endometriosis were also found to consult the doctor more frequently than the controls and were twice as likely to have time off work. CONCLUSIONS Specific symptoms and frequent medical consultation are associated with endometriosis and appear useful in the diagnosis. Endometriosis may coexist with or be misdiagnosed as pelvic inflammatory disease or IBS.

Abstract
BACKGROUND Epigallocatechin-3-gallate (EGCG), the major component of green tea, is a pleiotropic substance, which may inhibit tumor growth via multiple intracellular signaling pathways. Herein, we studied whether EGCG may also be effective in the treatment of endometriosis. METHODS We investigated the effect of EGCG on activation by estradiol (E(2)), proliferation and vascular endothelial growth factor (VEGF) expression of isolated hamster endometrial stromal cells and glandular cells in vitro using the water-soluble tetrazolium (WST)-1 colorimetric assay and western blot analysis. In the dorsal skinfold chamber model of Syrian golden hamsters, which were treated for 14 days with EGCG or vehicle, we further analyzed angiogenesis, blood perfusion and tissue integrity of both endometriotic lesions and ovarian follicles by intravital fluorescence microscopy and histology. RESULTS We found that EGCG suppresses E(2)-stimulated activation, proliferation and VEGF expression of endometrial cells in vitro (all P < 0.05). Furthermore, EGCG selectively inhibited angiogenesis and blood perfusion (P < 0.05) of endometriotic lesions in vivo without affecting blood vessel development in ovarian follicles. Histology confirmed that EGCG-treatment induces regression of the endometriotic lesions. CONCLUSIONS Our data indicate that EGCG might be a promising therapeutic agent in the treatment of endometriosis, preventing the establishment of new endometriotic lesions.

Abstract
OBJECTIVE To investigate the familial aggregation and the risk of endometriosis among the female relatives of women with endometriosis. We also compared the epidemiologic characteristics of women with and without family history of endometriosis. PATIENT(S) A total of 485 women with endometriosis and 197 infertile women without endometriosis underwent surgical investigation between August 1996 and February 2002. MAIN OUTCOME MEASURE(S) The relative risk of endometriosis in a first-degree relative and the association between potential risk factors was estimated by chi2 and by crude adjusted odds ratios (95% CI). RESULTS Endometriosis was identified in 9.5% of first-degree relatives of women with endometriosis versus only 1% of controls. The odds ratio for endometriosis in a first-degree relative was 10.21 (95% CI 2.45-42.5; P<0.001). In 3.9% of cases women with endometriosis reported that their mother had been diagnosed with endometriosis and 5.6% of cases that at least one sister had been diagnosed. Compared to the control group the odds ratio for the mother having endometriosis (7.99, 95% CI 1.06-60.1) or at least one sister having (11.55, 95% CI 1.56-85.59) were significantly elevated. Among women with endometriosis who reported a family history of endometriosis, and women with endometriosis who did not report a family history of endometriosis, there were no differences in demographic characteristics, body habitus, or menstrual parameters. CONCLUSION(S) Women with endometriosis have a tenfold increased risk of endometriosis in their first-degree relatives.

Abstract
OBJECTIVE To determine whether first physician seen and symptoms beginning in adolescence have an impact on the diagnostic experience of endometriosis. DESIGN Cross-sectional study of self-reported survey data. SETTING Academic research. PATIENT(S) Four thousand three hundred thirty-four Endometriosis Association Survey respondents reporting surgical diagnosis of endometriosis. INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) Specialty of first physician seen, timing of onset of symptoms, time to seeking medical care and to diagnosis, number of physicians seen, and satisfaction with care. RESULT(S) Almost all respondents reported pelvic pain. Fifty percent first saw a gynecologist and 45% saw a generalist for symptoms related to endometriosis. Two thirds reported symptoms beginning during adolescence; they waited longer to seek medical care than adults did. Those seeing a generalist first took longest to get diagnosed; those seeing a gynecologist first saw fewer physicians. Sometime before diagnosis, 63% were told nothing was wrong with them. CONCLUSION(S) Women and girls who reported seeing a gynecologist first for symptoms related to endometriosis were more likely to have a shorter time to diagnosis, to see fewer physicians, and to report a better experience overall with their physicians. The majority reported symptoms beginning during adolescence, also reporting a longer time and worse experience while obtaining a diagnosis.

Abstract
OBJECTIVE To evaluate serum and peritoneal fluid concentrations of interferon-gamma-inducible protein-10 (CXCL10), a chemokine involved in local immune function, in women with endometriosis. DESIGN Prospective study. SETTING Division of Obstetrics and Gynecology, University of Siena. PATIENT(S) A total of 147 women were divided in two groups: women with (n = 77) and without (n = 70) endometriosis. INTERVENTION(S) Serum and peritoneal fluid were collected from all patients undergoing laparoscopy. MAIN OUTCOME MEASURE(S) CXCL10 concentrations were measured by a specific ELISA. RESULT(S) Serum CXCL10 concentrations in women with endometriosis were significantly lower than in those without endometriosis. No statistically significant difference between women with early endometriosis and those with advanced endometriosis was found. CXCL10 concentrations in peritoneal fluid of women with advanced endometriosis were significantly lower than in that of women with an early stage of, or without, endometriosis. CONCLUSION(S) The decreased concentrations of CXCL10 in serum and peritoneal fluid of women with endometriosis indicate an impaired immune activity in women with endometriosis.
