Abstract
OBJECTIVE To assess in utero exposures and the odds of an endometriosis diagnosis. DESIGN Matched cohort design. SETTING Fourteen participating clinical centers in geographically defined areas in Utah and California. PATIENT(S) Operative cohort comprised 473 women undergoing laparoscopy/laparotomy, and an age- and residence-matched population cohort comprising 127 women undergoing pelvic magnetic resonance imaging (MRI), 2007-2009. INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) Women completed standardized interviews before surgery or MRI regarding in utero exposures: mothers' lifestyle during the index pregnancy, and the index woman's gestation and birth size. Endometriosis was defined as visually confirmed disease in the operative cohort, and MRI visualized disease in the population cohort. The odds of an endometriosis diagnosis and corresponding 95% confidence intervals (CI) were estimated for each exposure by cohort using logistic regression and adjusting for current smoking, age at menarche, body mass index, and study site. RESULT(S) Endometriosis was diagnosed in 41% and 11% of women in the operative and population cohorts, respectively. In the primary analysis, adjust odds ratios (AORs) were elevated for maternal vitamin usage (1.27; 95% CI, 0.85-1.91), maternal cigarette smoking (1.16; 95% CI = 0.61-2.24), and low birth weight (1.1; 95% CI, 0.92-1.32). Reduced odds were observed for maternal usage of caffeine (0.99; 95% CI, 0.64-1.54), alcohol (0.82; 95% CI, 0.35-1.94), paternal cigarette smoking (0.72; 95% CI, 0.43-1.19), and preterm delivery (0.98; 95% CI, 0.47-2.03). Sensitivity analyses mostly upheld the primary results except for a decreased AOR for preterm birth (0.41; 95% CI, 0.18-0.94) when restricting to visualized and histologically confirmed endometriosis in the operative cohort. CONCLUSION(S) In utero exposures were not statistically significantly associated with the odds of an endometriosis diagnosis in either cohort.

Abstract
Endometriosis, which affects up to 10 percent of reproductive-aged women, is the presence of endometrial tissue outside of the uterine cavity. It is more common in women with pelvic pain or infertility (25 to 40 percent and 70 to 90 percent, respectively). Some women with endometriosis are asymptomatic, whereas others present with symptoms such as debilitating pelvic pain, dysmenorrhea, dyspareunia, and decreased fertility. Diagnosis of endometriosis in primary care is predominantly clinical. Initial treatment includes common agents used for primary dysmenorrhea, such as nonsteroidal anti-inflammatory drugs, combination estrogen/progestin contraceptives, or progestin-only contraceptives. There is some evidence that these agents are helpful and have few adverse effects. Referral to a gynecologist is necessary if symptoms persist or the patient is unable to become pregnant. Laparoscopy is commonly used to confirm the diagnosis before additional treatments are pursued. Further treatments include gonadotropin-releasing hormone analogues, danazol, or surgical removal of ectopic endometrial tissue. These interventions may control symptoms more effectively than initial treatments, but they can have significant adverse effects and limits on duration of therapy.

Abstract
OBJECTIVE This study investigated the association between gynecological neoplasms, endometriosis, and adenomyosis in women who underwent surgical treatment for gynecological cancer and uterine leiomyoma during reproductive years or after menopause. MATERIALS AND METHODS Information was collected from patient records from the Hospital's database from 1985 to 2007. The study included 502 women, of which 375 were premenopausal and 132 were postmenopausal. RESULTS A significant association was observed between the occurrence of adenomyosis in cancer in women with four or more pregnancies, and in women aged over 40 years (p < 0.0001). The frequency of adenomyosis was significantly higher than the frequency of endometriosis for cancer in two sites (p = 0.0419) or for leiomyomas (p < 0.0001). CONCLUSION Therefore adenomyosis is more frequently found than endometriosis in women with leiomyomas or cancer in two sites in premenopausal women, and clinicians need to be aware of patients with adenomyosis and the risk of cancer.

Abstract
Women in Western nations are exposed to an "unnatural" high number of menstrual cycles and this has been claimed to favour the development of endometriosis. If so, the prevalence of the disease should be low in remote rural settings characterized by high fertility rate, frequent teen-age pregnancy and protracted breast-feeding. To verify this hypothesis, we investigated the prevalence of endometriosis among women referring to the District Hospital of Aber, Northern Uganda for gynecological complaints. Subjects were considered affected if they had a history of surgery for endometriosis or if they had a positive clinical or ultrasound examination. Overall, a total of 528 gynecological consultancies were performed during the one year study period. Endometriosis was recorded in only one case. The frequency of the disease in the whole cohort of referred cases was thus 0.2% (95% confidence intervals (CI): 0.01-0.9%). When focusing on non-pregnant women in their reproductive age, it was 0.3% (95% CI: 0.01-1.3%). When considering women complaining symptoms suggestive for endometriosis, it was 0.4% (95% CI: 0.02-1.9%). In conclusion, endometriosis is rare in a community characterized by high fertility rate, frequent teen-age pregnancy and protracted breast-feeding, supporting the idea that the reproductive pattern plays a crucial role in the pathogenesis of the disease.

Abstract
OBJECTIVE To investigate factors with pelvic adhesions and the effect of different degrees pelvic adhesions on fallopian tube recanalization in infertile patients. METHODS Total of 527 infertile patients undergoing hysteroscopy and laparoscopic surgery in Affiliated Hospital of Chinese People's Armed Police Forces Logistics College were studied retrospectively. According to the extent of pelvic adhesions, tubal umbrella adhesions and atresia, 377 cases were classified into adhesion groups, including 73 cases in grade I, 221 cases in grade II, 75 cases in grade III and 8 cases in grade IV based on adhesion score. The 150 cases with no obvious pelvic adhesion were matched as control group. Among 8 cases with grade IV ahesion were exluded from ahesion group the relationship between pelvic adhesions and related history, abdominal lesions, tubal patency and the prognosis were studied. RESULTS (1) Related factors: the frequency of pelvic adhesion and more than 7 years of infertility of 23.9% (88/369) in adhesion group were significantly higher than 12.0% (18/150) in control groups. (2) HISTORY: compared with the control group (12.7%, 19/150; 28.7%, 43/150; 11.3%, 17/150; 12.0%, 18/150; 17.3%, 26/150), patients with pelvic adhesions present more incidence abortion (23.6%, 87/369), uterine cavity operation (38.2%, 141/369), ectopic pregnancy (20.9%, 77/369), pelvic inflammatory disease (25.5%, 94/369) and abdominopelvic surgery (31.4%, 116/369). (3) Endoscopy exploration: the incidence of hydrosalpinx (24.7%, 91/369), tube distorted (15.7%, 58/369) and salpingostomy (72.9%, 269/369) in adhesion group were higher than those in control group (2.0%, 3/150; 4.0%, 6/150; 12.0%, 18/150), but relatively lower incidence of pelvic endometriosis lesions (5.7%, 21/369) and mesosalpinx cysts (16.3%, 60/369) than those in control group (16.0%, 24/150; 30.0%, 45/150). The rate of proximal tubal recanalization (59.5%, 91/153) in adhesion group was lower than 75.4% (52/69) in control group. However, the rate of distant tubal recanalization of 84.4%, (281/333) in adhesion group and; 13/15 in control group didn't show statistical difference. (4) PROGNOSIS: the rate of ectopic pregnancy of 9.7% (29/299) in adhesion group was significantly higher than 3.1% (4/128) in control group. Among cases with grade III adhesion exhibited the highest rate of ectopic pregnancy (13.0%, 7/54; OR = 4.62, 95%CI: 1.29 - 16.50). (5) Multivariate analysis: it was found that more than two drug abortions (OR = 3.29, 95%CI: 1.34 - 8.07), pelvic and(or) abdominal surgery history (OR = 2.20, 95%CI: 1.35 - 3.57) and pelvic inflammatory disease history (OR = 1.54, 95%CI: 1.21 - 1.97) were risk factors with pelvic adhesions. CONCLUSION More than or equal to two drug abortion history, pelvic inflammatory disease and pelvic and abdominal surgery damage were important factors for pelvic adhesions of infertility patients, which may decrease the possibility of proximal tubal recanalization and increase ectopic pregnancy risk.

Abstract
BACKGROUND Endometriosis no ectopic endometrial stroma and glands. Have different risk factors. Four theories explain it: the theory of coelomic metaplasia, embryonic cell debris, deployment and immunological. Clinical data are pain and infertility. For the American Fertility Society (AFS) is divided into minimal, mild, moderate and severe. Diagnostic studies are antigen Ca 125, Magnetic Resonance, and abdominal ultrasound. The ideal method is direct visualization with histological confirmation. The medical and surgical treatment. OBJECTIVE To determine the risk factors, diagnosis of Endometriosis and effectiveness of treatments used in clinical Endometriosis Gynecology Unit at the General Hospital of Mexico OD. MATERIAL AND METHODS A descriptive, longitudinal and retrospective duration of 2 years 6 months in 30 patients diagnosed with endometriosis in the clinical treatment of Endometriosis General Hospital of Mexico OD. RESULTS The most affected age group was 21 to 25 years, the risk factors are Gesta 1, a resident of Mexico, Mullerian malformation. The symptom was dysmenorrhea. In 16 were diagnosed as a surgical finding and laparoscopically diagnosed. CONCLUSIONS It is important to study the risk factors. The diagnosis is made using clinical data, quantification of CA125 antigen and imaging studies. Medical treatment is indicated both in the preoperative as well as postoperative surgical treatment and seeks to eradicate the lesions.

Abstract
Chronic pelvic pain is a complex condition that requires evaluation of the reproductive, gastrointestinal, urologic, musculoskeletal, psychological, and neurological systems. Usually, diagnosis and management entail identifying a network of disorders rather than a single cause of pain with a definitive cure. Only disorders that we commonly encounter in our practice will be discussed in this review.

Abstract
BACKGROUND An equivocal literature exists regarding the relation between persistent organochlorine pollutants (POPs) and endometriosis in women, with differences attributed to methodologies. OBJECTIVES We assessed the association between POPs and the odds of an endometriosis diagnosis and the consistency of findings by biological medium and study cohort. METHODS Using a matched cohort design, we assembled an operative cohort of women 18-44 years of age undergoing laparoscopy or laparotomy at 14 participating clinical centers from 2007 to 2009 and a population-based cohort matched on age and residence within a 50-mile catchment area of the clinical centers. Endometriosis was defined as visualized disease in the operative cohort and as diagnosed by magnetic resonance imaging in the population cohort. Logistic regression analysis was used to estimate odds ratios (ORs) and 95% confidence intervals (CIs) for each POP in relation to an endometriosis diagnosis, with separate models run for each medium (omental fat in the operative cohort, serum in both cohorts) and cohort. Adjusted models included age, body mass index, breast-feeding conditional on parity, cotinine, and lipids. RESULTS Concentrations were higher in omental fat than in serum for all POPs. In the operative cohort, γ-hexachlorocyclohexane (γ-HCH) was the only POP with a significant positive association with endometriosis [per 1-SD increase in log-transformed γ-HCH: adjusted OR (AOR) = 1.27; 95% CI: 1.01, 1.59]; β-HCH was the only significant predictor in the population cohort (per 1-SD increase in log-transformed β-HCH: AOR = 1.72; 95% CI: 1.09, 2.72). CONCLUSIONS Using a matched cohort design, we found that cohort-specific and biological-medium-specific POPs were associated with endometriosis, underscoring the importance of methodological considerations when interpreting findings.

Abstract
Vascular endothelial growth factor (VEGF) is known to be a key molecule in the pathogenesis of endometriosis. In this study, we evaluated whether two polymorphisms -460T>C and +405G>C in VEGF are related with the susceptibility to endometriosis in northern Iran. Genomic DNA derived from patients with endometriosis and healthy women were analysed by polymerase chain reaction-restriction fragment length polymorphism. The total number of 1080 subjects (480 patients with endometriosis and 600 normal controls) was enrolled into the study. We used the Chi-square (χ(2)) test to evaluate each allele and genotype frequency of -460T>C and +405G>C polymorphisms among the cases and controls. The associations between the polymorphisms and the risk of endometriosis were estimated by odds ratio and their 95% confidence intervals. There was no significant differences in the VEGF -460T>C genotypes and allele frequencies between control women and endometriosis patients (P = 0.63). In contrast, an increased frequency of the +405CC genotype was observed in the patients with endometriosis as compared with the controls. The +405C allele was associated with the presence of endometriosis. It is concluded that the +405G>C polymorphism in VEGF may be associated with higher risk of endometriosis in northern Iran.

Abstract
Endometriosis is usually described as a complex multifactorial disease involving dysregulation of estrogen metabolism, inflammatory and immunological mechanisms. Recently, many authors have questioned the environmental pollution and toxins in the formation and development of endometriotic lesions. Therefore, while dioxins and PCBs have been implicated, insufficient data are available until now to confirm this theory. Endometriosis has also been considered as a genetic disease. Indeed, early familial aggregation and twin studies noted a higher risk of endometriosis among relatives. However, demonstration of a genetic component in the pathogenesis of such a multifactorial disease is quite difficult due to many limitations such as ethnic differences, involvement of environmental factors and size of needed patients cohorts. Over the last decade, the epigenetic approach (DNA methylation, histones modifications and microRNA) has allowed to consider many new perspectives. Indeed, dysregulation (hyper- or hypomethylation) of many genes has already been highlighted. This method of analysis is the subject of numerous studies in order to develop diagnostic, prognostic and therapeutic tools for this disease which is becoming a real public health problem.

Abstract
Benzophenone (BP)-type UV filters are widely used in a variety of personal care products for the protection of skin and hair from UV irradiation. Despite the estrogenic potencies of BP derivatives, few studies have examined the occurrence of these compounds in human matrices. Furthermore, associations among exposure to these compounds and estrogen-dependent diseases (such as endometriosis) have not been examined previously. In this study, we determined the concentrations of five BP derivatives, 2-hydroxy-4-methoxybenzophenone (2OH-4MeO-BP), 2,4-dihydroxybenzophenone (2,4OH-BP), 2,2'-dihydroxy-4-methoxybenzophenone (2,2'OH-4MeO-BP), 2,2',4,4'-tetrahydroxybenzophenone (2,2',4,4'OH-BP), and 4-hydroxybenzophenone (4OH-BP), in urine collected from 625 women in Utah and California, using liquid chromatography (LC)-tandem mass spectrometry (MS/MS). The association of urinary concentrations of BP derivatives with an increase in the odds of a diagnosis of endometriosis was examined in 600 women who underwent laparoscopy/laparotomy (n = 473: operative cohort) or pelvic magnetic resonance imaging (n = 127: population cohort), during 2007-2009. 2OH-4MeO-BP, 2,4OH-BP, and 4OH-BP respectively were detected in 99.0%, 93.3%, and 83.8% of the urine samples analyzed, whereas the detection rates for 2,2',4,4'OH-BP and 2,2'OH-4MeO-BP were below 6.0%. Significant regional differences (higher concentrations in California) and monthly variations (higher concentrations in July and August) were found for urinary concentrations of 2OH-4MeO-BP and 2,4OH-BP. In addition, urinary concentrations of 2OH-4MeO-BP and 2,4OH-BP tended to be higher in more affluent, older, and leaner women. Adjusted odds ratios (ORs) and 95% confidence intervals (CIs) were estimated for the urinary concentrations of BP derivatives and the odds of an endometriosis diagnosis; ORs increased across quartiles of 2OH-4MeO-BP and 2,4OH-BP concentrations, but a significant trend was observed only between 2,4OH-BP and the odds of an endometriosis diagnosis in the operative cohort (OR = 1.19; 95% CI = 1.01, 1.41). When women in the highest quartile of 2,4OH-BP concentrations were compared with women in the first three quartiles, the OR increased considerably (OR = 1.65; 95% CI = 1.07, 2.53). Given that 2,4OH-BP possesses an estrogenic activity higher than that of 2OH-4MeO-BP, our results invite the speculation that exposure to elevated 2,4OH-BP levels may be associated with endometriosis.

Abstract
BACKGROUND Postmenopausal endometriosis is rare. The purpose of this presentation is to give a review of the topic based on existing literature. METHODS A Medline search concerning postmenopausal endometriosis was carried out. Hormone therapy and risk of malignancy in these patients are discussed. RESULTS Some 32 case reports on postmenopausal endometriosis were found. The most common location is in the ovaries. Estrogens stimulate endometriosis. There is a risk of recurrence or de novo occurrence of endometriosis after the menopause in patients who take hormone therapy (HT); especially estrogen only therapy (ET). So far, treatment has primarily been surgery (hysterectomy (TAH) and bilateral oophorectomy (BSO)).There is little experience with medical treatment (aromatase inhibitors). The risk of malignant transformation of premenopausal endometriosis is around 1%. Furthermore, patients with endometriosis have an increased risk of ovarian cancer, and, apparently, other malignancies. The risk of malignant transformation appears to be further elevated in patients who take ET, although this subject is not fully elucidated. CONCLUSIONS Although the condition is rare, it is important to be aware of endometriosis after the menopause. Postmenopausal endometriosis infers a risk of recurrence and malignant transformation. Although solid evidence is lacking, the risk of malignant transformation appears to be lower during combined HT compared to ET. Thus, hormone replacement therapy should generally be reserved for patients with severe climacteric complaints, and if indicated, combined therapy should be used.

Abstract
OBJECTIVE The purpose of this study was to determine outcomes, after the use of propensity score techniques, to create balanced groups according to whether a woman undergoes elective repeat cesarean delivery (ERCD) or trial of labor (TOL). STUDY DESIGN Women who were eligible for a TOL with 1 previous low transverse incision were categorized according to whether they underwent an ERCD or TOL. A propensity score technique was used to develop ERCD and TOL groups with comparable baseline characteristics. Outcomes were assessed with conditional logistic regression. RESULTS The rates of endometritis, operative injury, respiratory distress syndrome, and newborn infant infection were lower and the rates of hysterectomy and wound complication were higher in the ERCD group. CONCLUSION Propensity score techniques can be used to generate comparable ERCD and TOL groups. Some types of maternal morbidity (such as hysterectomy) are higher; other types (such as operative injury) are lower in the ERCD group. Although the absolute risk is low, neonatal morbidity appears to be lower in the ERCD group.

Abstract
STUDY OBJECTIVE To compare the incidence of new-onset endometriosis after laparoscopic supracervical hysterectomy (LSH) with uterine morcellation to traditional routes. DESIGN Single center case-control study (Canadian Task Force classification II-2) of hysterectomies performed from January 2006 through December 2008. PATIENTS Two hundred seventy-seven laparoscopic supracervical hysterectomies with morcellation (cases) and 187 transvaginal or abdominal hysterectomies without morcellation (controls) were performed from January 2006 through December 2008. INTERVENTIONS A total of 464 women underwent hysterectomy, 277 cases via laparoscopic supracervical approach (LSH) with morcellation and 187 performed either transvaginally or abdominally without morcellation. Repeat operative procedures were performed for other benign indications on 16 of 464 (3.5%) patients who had undergone prior hysterectomy. MEASUREMENTS AND MAIN RESULTS One hundred two patients had endometriosis at the time of hysterectomy diagnosed by pathologic evaluation or gross visualization. In those without endometriosis, repeat operative procedures were performed for pain and bleeding in 3.3% (12/362). Sixty percent (3/5) of patients treated with LSH and 28.6% (2/7) of the control group were found to have newly diagnosed endometriosis, conferring a rate of 1.4% (3/217) in the LSH group and 1.4% (2/145) in the control subjects. In patients with endometriosis, repeat operative procedures for pain or bleeding occurred in 2.9% (3/102): 3/60 patients treated with LSH and none in the control group (0/42). Two of these 3 patients undergoing a second surgery had recurrent/continued endometriosis. CONCLUSION Newly diagnosed endometriosis was noted in 1.4% of patients after hysterectomy, with a similar incidence between the LSH and control groups. Reoperation for those with endometriosis at the time of LSH with morcellation was infrequent, but endometriosis was usually found. Further research is needed to delineate risk factors for development of de novo endometriosis after hysterectomy.

Abstract
Endometriosis is one of the frequent gynecological diseases in premenopausal women. The clinical diagnostics is difficult because symptoms of endometriosis are variable. The surgical removal of endometriosis is the primary therapeutic aim. Medical treatment plays a very important role in the therapy of this chronic disease. A symptomatic therapy by analgetics should be combined with a hormonal treatment. The use of oral contraceptives in extended cycle or long-term use is effective against endometriosis associated pain. Progestogens, especially dienogest, which is licensed for endometriosis treatment and good investigated, are very effective and also available for long-term use. GnRH-analogues are effective for a short-term treatment (duration of 3 months). The long-term treatment with GnRH-analogues should only be used in selected cases and in combination with an add back therapy. Treatment of endometriosis should be planned individually for each patient, dependent on stage, localization and activity of endometriosis and further family planning. By the combination of hormonal and operative treatment possibilities a maximum period free of pain or recurrence of endometriosis can be reached.

Abstract
OBJECTIVE To establish a well-defined cohort for genetic epidemiology studies of endometriosis and conduct a pilot study to confirm validity using existing data associated with endometriosis. METHODS Between January and May 2010, a nested cohort within a population-based biobank was established in Marshfield, Wisconsin, USA. The inclusion criteria were women who had laparoscopy or hysterectomy. Fifty-one pleiotropic genetic polymorphisms and other established risk factors, such as smoking status and body mass index, were compared between endometriosis cases and controls. RESULTS From the existing biobank, 796 cases and 501 controls were identified, and 259 women with endometriosis were enrolled specifically for the nested cohort within this biobank. A single nucleotide polymorphism in the MMP1 gene significantly differed between cases and controls only when stratified by smoking status. Minor allele frequency was higher in control women who smoked than in women with endometriosis who smoked (55.5% versus 45.5%, χ(2)=8.2, P=0.017); the inverse relationship was found in non-smoker control women. CONCLUSIONS Women with endometriosis were successfully recruited to participate in a general biobank, and a novel gene-environment interaction was identified. The findings suggest that important potential genetic associations may be missed if gene-environment interactions with known epidemiologic risk factors are not considered.

Abstract
Headache and endometriosis show some similarities in their clinical and epidemiological features that are probably due to the influence of female sexual hormones on both disorders. Epidemiological studies indicate that they are comorbid disorders. However, the nature of the comorbidity is not known with certainty, but a likely explanation may be common susceptibility genes. Another possibility is that, because they both are related to pain, increased pain sensitivity induced by one of the disorders may lead to a higher likelihood of developing the other, possibly mediated by nitrogen oxide or prostaglandins. A common link to the widespread use of estroprogestins may seem less probable. For physicians dealing with women with either of these disorders, awareness of the comorbidity may be helpful in the treatment of the patient.

Abstract
OBJECTIVE To determine the frequency of uterine leiomyomas and hysterectomy in patients with lymphangioleiomyomatosis (LAM), a disease characterized by proliferation of abnormal-appearing smooth muscle-like cells. DESIGN Retrospective study. SETTING Natural history study at the National Institutes of Health. PATIENT(S) 456 patients with sporadic LAM and LAM associated with tuberous sclerosis complex (LAM/TSC). INTERVENTION(S) Review of records and pelvic computed axial tomography scans. MAIN OUTCOME MEASURE(S) Prevalence of uterine leiomyomas and hysterectomy. RESULT(S) A total of 174 women had uterine leiomyomas (38%). One hundred eighteen were diagnosed by computed tomographic scan and 56 were diagnosed by hysterectomy. Among 323 patients who did not have hysterectomy, 105 of 270 patients (39%) with sporadic LAM and 13 of 53 (25%) with LAM/TSC had uterine leiomyomas. Hysterectomy was performed in 108 of 378 subjects with sporadic LAM and 25 of 78 with LAM/TSC. Fifty-six patients were found to have uterine fibroids on hysterectomy. The most common indications for hysterectomy were uterine leiomyoma, LAM, and endometriosis. CONCLUSION(S) Uterine leiomyomas are not more common in LAM than in the general population. However, in LAM, the frequency of hysterectomy is higher because of it having been recommended for treatment of LAM.

Abstract
OBJECTIVE We sought to describe the pattern of age at menopause and factors associated with type of menopause. STUDY DESIGN This was a prospective cohort study of 5113 postmenopausal health survey respondents in the Royal College of General Practitioners' Oral Contraception Study. Logistic regression was used to evaluate associations between sociodemographics, lifestyle, and medical history and menopause type. RESULTS Median age at natural menopause (n = 3650) was 49.0 years (interquartile range, 45.0-51.0), and at surgical menopause (n = 1463) was 42.4 years (38.0-46.4). Early natural menopause was associated with smoking, ever-use of oral contraception, sterilization, and history of endometriosis (all increased odds ratios) and ever-use of hormone replacement therapy (decreased). Surgical menopause was associated with manual social class, sterilization, and having a history of endometriosis, menorrhagia, or painful menstruation (all increased), and ever-use of hormone replacement therapy (decreased). CONCLUSION Age at natural menopause was younger in this cohort than in other studies. More associations were found for surgical menopause than early natural menopause.

Abstract
Bilateral oophorectomy is often performed during hysterectomy for benign conditions and can reduce breast cancer risk by 20%-50% when performed at younger ages. Accuracy of estimating the decrease in breast cancer risk associated with bilateral oophorectomy could be affected by common conditions that lead to surgery, such as uterine fibroids or endometriosis. The authors examined the potential for confounding by nonmalignant indications for surgery on breast cancer risk estimates in a population-based case-control study of invasive breast cancer newly diagnosed in 1992-1995. Breast cancer cases (N = 4,935) aged 50-79 years were identified from Wisconsin, Massachusetts, and New Hampshire tumor registries; similarly aged controls (N = 5,111) were selected from driver's license and Medicare lists. Reproductive and medical history was obtained from structured telephone interviews. Odds ratios and 95% confidence intervals were estimated with multivariate logistic regression. Women who underwent bilateral oophorectomy with hysterectomy at age ≤ 40 years had significantly reduced odds of breast cancer (odds ratio = 0.74, 95% confidence interval: 0.60, 0.90) compared with women with intact ovaries and uterus. Effect estimates were virtually unchanged after adjustment for uterine fibroids or endometriosis history. Results indicate that breast cancer risk reductions conferred by bilateral oophorectomy are not strongly confounded by failure to account for nonmalignant indications for surgery.

Abstract
PURPOSE to evaluate the frequency and clinical picture of patients with incisional endometriosis. METHODS retrospective descriptive study performed from the medical records of patients that underwent nodules resection in the surgical scar at Faculdade de Medicina do ABC, from November 1990 to September 2003. The age, parity, number of cesarean sections, symptoms, tumor location, initial diagnosis, treatment, and recurrences were surveyed and analyzed. The results were reported as percentage, mean, and standard deviation. RESULTS we found 42 patients that were diagnosed with scar endometriosis. From these 42 cases, 37 were of endometriosis on cesarean section scar; 3 cases of episiotomies and 2 cases on bladder in scar of hysterography. The mean age of the patients was 32.4 years old, standard deviation of ±6.2 years. All of them had previous obstetric surgery, and the main complaint was nodulation with perimenstrual pain in 40% of the cases. In 57% of the patients, the clinical evaluation was confirmed by pelvic or transvaginal ultrasonography. Patients were treated with total resection, and recurrence occurred in only two cases. CONCLUSION scar surgical endometriosis is uncommon; however, the clinical diagnosis is easy when the signs and symptoms are known. The effective treatment is surgical resection.
