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 Cumulative evidence supports the view that ovarian endometriomas originate from ovulatory events and that the ovarian reserve is reduced following surgery. On these bases, we have hypothesized that the risk of recurrence may be related to the residual ovarian reserve of the operated ovary. STUDY DESIGN We retrospectively selected 45 women scheduled for in vitro fertilization who previously underwent surgical excision of monolateral endometriomas and compared ovarian responsiveness in those who did (n = 24) and did not (n = 21) have a recurrent endometrioma. RESULTS In the intact ovaries, the mean ± SD number of codominant follicles in women with and without recurrences was 3.5 ± 1.7 and 3.7 ± 2.2, respectively (P = NS). In the affected ovaries, the mean ± SD number of follicles in gonads with and without recurrences was 2.5 ± 2.3 and 1.1 ± 1.5, respectively (P < .05). CONCLUSION Ovarian responsiveness is higher in gonads that developed recurrent endometriomas.

Abstract
BACKGROUND/AIMS Perinatal environmental exposure may affect fetal development and reprogram the developing organism for adult-onset disease. In this case-control study, we aimed at assessing this pathogenetic model in endometriosis. METHODS Consecutive patients with a first laparoscopic diagnosis of endometriosis were selected as cases. Controls were women who underwent laparoscopy during the same study period, but who were found to be free of the disease. Selected women and their mothers were interviewed. RESULTS Ninety-one women with endometriosis and 82 controls were selected. Handedness, a variable believed to be determined prenatally by hormonal environment in utero significantly differed between the study groups. Women with the disease were less likely to be left- or mixed-handed (adjusted OR: 0.24, 95% CI: 0.08-0.71). In contrast, we failed to detect any association with birth order, maternal age, smoking, nausea, weight gain, prematurity, birth weight and breast-feeding. CONCLUSIONS Our results generally do not support the view that in utero exposure may play a major role in the pathogenesis of endometriosis. The association with handedness, however, is intriguing in this regard and deserves further investigation.

Abstract
AIM We carried out an association study between T-cell receptor beta polymorphism (TCRB) and endometriosis to investigate the difference in allelic frequency. Polymorphisms in T-cell receptor genes can provide important information for the study of the immune response and autoimmune diseases; indeed, rs1800907, a very common single nucleotide polymorphism (SNP) of the TCRB, has been extensively studied in autoimmune diseases in the 1990s using Southern blot analysis and more recently polymerase chain reaction (PCR) and sequencing. An autoimmune etiology for endometriosis has been strongly suggested for the presence of antibodies against endometrium, high rates of autoimmune disorders and associated atopic diseases. MATERIAL AND METHODS We investigated 70 patients with endometriosis and 120 controls. DNA of patients and controls was studied by PCR followed by restriction digestion and sequencing to determine genotype and presence of linkage disequilibrium (LD). Statistical analysis was carried out using STATA Routine GENHW (StataCorp, College Station, TX, USA) for estimation of Hardy-Weinberg equilibrium and test power calculation. The difference of allele distribution between patients and controls was calculated according to Pearson's and Fisher's tests. Test power for the estimation of linkage disequilibrium is low (0.16). RESULTS We performed an association study of the SNP rs1800907 of TCRB between 70 patients with endometriosis and 120 controls, and did not find any significant difference (χ(2) = 0.27 and P = 0.87). Fisher's test confirmed a P-value of 0.872. CONCLUSION Our study does not suggest an evidential and major involvement of TCRB in the pathogenesis of endometriosis in an Italian population in a small case control study.

Abstract
BACKGROUND There is a growing consensus that ovarian reserve is reduced after surgical excision of ovarian endometriomas. However, it remains to be fully clarified whether this damage precedes or follows surgery. In order to further elucidate this aspect, we evaluated ovarian responsiveness to hyperstimulation in women selected for IVF with unilateral unoperated endometriomas. The main aim of this study was to compare the number of developing follicles in the affected ovary with that in the contralateral intact gonad as a control. METHODS Patients selected for IVF who were diagnosed with one or more monolateral endometriomas (diameter <4 cm) and who did not undergo previous ovarian surgery were retrospectively identified. We compared the number of follicles (diameter ≥ 11 mm) and the number of co-dominant follicles (diameter >15 mm) on the day of hCG administration in the affected and intact ovaries. RESULTS Among the 84 women selected, the median interquartile range (IQR) number of follicles ≥ 11 mm in the affected and intact ovaries was 5 (3-7) and 5 (3-8), respectively (P= 0.36). The median (IQR) number of co-dominant follicles in the affected and intact ovaries was 3 (2-4) and 3 (2-5), respectively (P= 0.48). The number of co-dominant follicles was lower in the affected ovary in 36 cases (43%, 95% confidence interval: 32-53%). We also failed to identify any statistically significant difference between the two ovaries when evaluating data according to the number of cysts, their dimension, the dose of gonadotrophins used or the number of oocytes retrieved. CONCLUSIONS In women selected for IVF, the presence of an endometrioma does not markedly affect responsiveness to hyperstimulation.

Abstract
BACKGROUND The impact of fibroids, not encroaching the endometrial cavity, have on the rate of success of IVF is still controversial. Recent meta-analyses suggest a detrimental effect of intramural lesions but not subserosal lesions. However, they also emphasize the need for further evidence. In order to elucidate this, we designed a prospective cohort study to compare the rate of success of IVF in women with and without fibroids. METHODS Exposed women were those with asymptomatic intramural or subserosal fibroids with a diameter below 50 mm and who were selected for IVF. Unexposed women were those free of fibroids, who were matched to cases by age and number of previous IVF cycles. All recruited patients underwent hystero-sonography to rule out intra-cavitary lesions. RESULTS There were 119 cases and 119 controls recruited. The number of clinical pregnancies in women with and without fibroids was 28 (24%) and 22 (19%), respectively (P= 0.43). The adjusted odds ratio (OR) for pregnancy in affected women was 1.38 [95% confidence interval (CI): 0.73-2.60]. The number of deliveries was 22 (18%) and 16 (13%), respectively (P= 0.38). The adjusted OR was 1.45 (95% CI: 0.71-2.94). Similar results emerged when focusing exclusively on women carrying intramural lesions (n= 80 couples). There was no significant relationship between clinical outcome and either the number or size of the fibroids. CONCLUSIONS In asymptomatic patients selected for IVF, small fibroids not encroaching the endometrial cavity did not impact on the rate of success of the procedure.

Abstract
To evaluate the influence of IVF on the dimension of leiomyomas, we selected 72 women with small intramural or subserosal leiomyomas and assessed the size of these lesions before and after the treatment cycle. The mean ± SD diameters of the tumors at these two time points were 20.5 ± 9.5 and 20.6 ± 10.2 mm, respectively, thus supporting the conclusion that IVF does not influence the growth of these lesions.

Abstract
The number of women with congenital heart disease reaching childbearing age is constantly increasing due to the advances achieved in cardiac surgery during the past decades. The significant physiological haemodynamic changes and adaptations of the cardiovascular system associated with pregnancy, birth and puerperium increases the cardiovascular risk to pregnant women with congenital heart disease. It is therefore necessary not only the awareness of these haemodynamic changes and risks, but also a multidisciplinary approach that involves preconception counseling, choosing the best contraceptive method, close surveillance during pregnancy, delivery and puerperium. The purpose of this article is to review the major risks associated with pregnancy in women with CHD and to provide an indication on the best contraceptive method and cares during pregnancy in these patients.

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
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
BACKGROUND There is limited but interesting evidence suggesting that endometriosis may be associated with specific pigmentary traits and sun habits. In this case-control study, we aimed to further clarify this point. MATERIALS AND METHODS Consecutive patients with a first laparoscopic diagnosis of endometriosis according to Holt and Weiss criteria were selected as cases. Controls were women who underwent laparoscopy during the same study period, but who were found to be free of the disease. Selected women were interviewed and examined by two trained physicians. An unconditional logistic regression model that included age and baseline variables significantly differing between the two groups was used to estimate the adjusted odds ratios (OR). RESULTS There were 98 women with endometriosis and 94 controls selected. Overall, women with the disease had a more photo-sensitive phenotype and were exposed less to sun or ultraviolet radiation. A statistically significant difference was documented for eye color, skin reaction to first sun exposure, freckles score and the use of tanning creams. The adjusted OR (95% CI) for the disease was 1.95 (1.02-3.72) for women with green/blue eyes, 2.19 (1.12-4.28) for those who frequently/always had skin burn reaction to first sun exposure, 5.67 (1.98-16.24) for those with a higher number of freckles and 0.35 (0.15-0.85) for the use of tanning creams. CONCLUSIONS Women with endometriosis have a specific photo-sensitive phenotype and protect themselves more from the sun. This latter habit may be consequent to the former. We speculate that there is a shared genetic background between pigmentation and endometriosis.

Abstract
Estimates of endometriosis recurrence after primary surgery are around 10% per annum during the first postoperative quinquennium. The aim of this study was to define the effect of reoperation in women seeking conception. A MEDLINE and PubMed search was conducted to identify English language studies published in the last 30 years evaluating reproductive performance after second-line surgery. Repeat surgery for recurrent endometriosis and identification of women seeking pregnancy were selected. Two authors abstracted data on standardized forms. The initial literature screening yielded 41 citations, but 19 were excluded because no data on reoperation were described, seven as no original figures were included, three because analyses were performed on the same cohort, and one because extremely skewed data were reported. A total of 313 patients who sought pregnancy after repetitive surgery for recurrent endometriosis were found, 139 in six non-comparative studies, and 174 in five retrospective comparative studies. Overall, pregnancy was achieved in 81 women (26%; 95% confidence interval (CI), 21-31%), without significant difference between the laparotomy (27%) and laparoscopy (25%) approach. Three studies compared pregnancy rate after second-line (28/124; 23%) and primary surgery (236/577; 41%; common odds ratio (OR), 0.44; 95% CI, 0.28-0.68%), and two compared the probability of conception after in-vitro fertilization (IVF) (14/27; 30%) and repetitive surgery (10/50; 20%; common OR, 1.51; 95% CI, 0.58-3.91%). Conclusions. The probability of conception after repeat surgery for recurrent endometriosis appeared limited and reduced compared with that after primary surgery. The results of IVF were not inferior to those of reoperation.

Abstract
BACKGROUND Mayer-Rokitansky-Kuster-Hauser syndrome (MRKH) consists of congenital aplasia of the uterus and the upper part of vagina due to anomalous development of Müllerian ducts, either isolated or associated with other congenital malformations, including renal, skeletal, hearing and heart defects. This disorder has an incidence of approximately 1 in 4500 newborn girls and the aetiology is poorly understood. METHODS AND RESULTS we report on two patients affected by MRKH syndrome in which array-CGH analysis disclosed an identical deletion spanning 1.5 Mb of genomic DNA at chromosome 17q12. One patient was affected by complete absence of uterus and vagina, with bilaterally normal ovaries, while the other displayed agenesis of the upper part of vagina, right unicornuate uterus, non cavitating rudimentary left horn and bilaterally multicystic kidneys. The deletion encompassed two candidate genes, TCF2 and LHX1. Mutational screening of these genes in a selected group of 20 MRKH females without 17q12 deletion was negative. CONCLUSION Deletion 17q12 is a rare albeit recurrent anomaly mediated by segmental duplications, previously reported in subjects with developmental kidney abnormalities and diabetes. The present two patients expand the clinical spectrum associated with this imbalance and suggest that this region is a candidate locus for a subset of MRKH syndrome individuals, with or without renal defects.

Abstract
BACKGROUND Rectovaginal endometriosis usually causes distressing pain. Surgical treatment may be effective but is associated with a high risk of morbidity and major complications. Information on the effect of medical alternatives for pain relief in this condition is scarce. METHODS A comprehensive literature search was conducted to identify all the English language published observational and randomized studies evaluating the efficacy of medical treatments on pain associated with rectovaginal endometriosis. A combination of keywords was used to identify relevant citations in PubMed, MEDLINE and EMBASE. RESULTS A total of 217 cases of medically treated rectovaginal endometriosis were found; 68 in five observational, non-comparative studies, 59 in one patient preference cohort study, and 90 in a randomized controlled trial. An aromatase inhibitor was used in two of the non-comparative studies, vaginal danazol in one, a GnRH agonist in one, and an intrauterine progestin in one. Two estrogen-progestin combinations used transvaginally or transdermally were evaluated in the patient preference study, whereas an oral progestin and an estrogen-progestin combination were compared in the randomized controlled trial. With the exception of an aromatase inhibitor used alone, the antalgic effect of the considered medical therapies was high for the entire treatment period (from 6 to 12 months), with 60-90% of patients reporting considerable reduction or complete relief from pain symptoms. CONCLUSIONS Despite problems in interpretation of data, the effect of medical treatment in terms of pain relief in women with rectovaginal endometriosis appear substantial.

Abstract
In spite of the increasing number of operative laparoscopies performed for endometriosis associated pelvic pain, postoperative symptomatic recurrences are very common. Reoperation is often considered the best treatment option, but the extent and duration of the effect of second-line surgery is still unclear. The best available evidence has been reviewed in order to define the results of repetitive conservative surgery, the effects of pelvic denervating procedures and postoperative medical treatments, as well as the long-term outcome of definitive surgery. Because of the paucity of published data, estimating the real risk of symptomatic recurrence and need for reoperation after repetitive conservative surgery for endometriosis is very difficult. Based on the limited information available, the long-term outcome appears suboptimal, with a cumulative probability of pain recurrence between 20% and 40%, and of a further surgical procedure between 15% and 20%. These figures are probably an underestimate related to drawbacks in study design, exclusions of dropouts, and publication bias and should be considered with caution. Systematic complementary performance of denervating procedures in addition to reoperation cannot be recommended, as only a few symptomatic patients complain of predominantly midline, hypo-gastric pain. The outcome of hysterectomy for endometriosis-associated pain at medium-term follow-up seems quite satisfactory. Nevertheless, about 15% of patients had persistent symptoms, and 3-5% experienced worsening of pain. Concomitant bilateral oophorectomy reduced the risk of reoperation due to recurrent pelvic pain by six times. However, at least one gonad should be preserved in young women, especially in those with objections to the use of oestrogen-progestogens. Medical treatment appears to have limited and inconsistent effects when used for only a few months after conservative procedures. Data on the benefit of prolonged drug regimens with oral contraceptives or progestogen are lacking. The risk of recurrence of endometriosis during hormone replacement therapy seems marginal if combined preparations or tibolone are used and oestrogen-only treatments are avoided. The opportune surgical solution in women with recurrent symptoms after previous conservative procedures for endometriosis should be based on the desire for conception as well as on psychological characteristics. Studies on surgical management of recurrent rectovaginal endometriosis are warranted, due to the peculiar technical difficulties as well as the high risk of complications associated with this challenging disease form.

Abstract
PURPOSE We evaluated the accuracy of magnetic resonance imaging (MRI) in young women with primary amenorrhoea with suspected Mayer-Rokitansky-Kuster-Hauser (MRKH) syndrome (congenital absence of both vagina and uterus and presence of normal ovaries). MATERIALS AND METHODS Fifty-eight women (age range 14-30 years, mean 20.9) with primary amenorrhea were studied with MRI performed with a 1.0-T superconducting magnet (Philips NT Intera). All patients were examined in the supine position using a phased-array coil (four channels). Turbo spin-echo T2-weighted images were acquired in the sagittal, axial and coronal planes with the following parameters: TR 4,750-6,686, TE 100-120, FOV 350-375, 4- to 5-mm sections with a 0.4- to 0.5-mm intersection gap and NSA 6. T1-weighted images were acquired in the axial and coronal planes (TR 470, TE 15, FOV 350, 4-mm sections with a 0.6-mm intersection gap, NSA 3). Two experienced radiologists evaluated all the examinations in consensus to assess the presence, position and morphology of vagina, uterus, ovaries and kidneys and any pelvic abnormalities. MRI results were judged on the basis of laparoscopic findings in 41 patients. RESULTS MRKH syndrome was confirmed in 56 patients with 100% sensitivity and specificity. MRI identified bilateral Müllerian buds in 34/56 (61%) and unilateral in 10/56 (18%) patients. MRI sensitivity was 81.42%, and there was good agreement with laparoscopy (k=0.55) and full agreement in the identification of cavitation between MRI and intraoperative sonography. Both ovaries were visualised in 54 patients, with regular morphology in 46 (82.1%), polycystic in 10 (17.8%), pelvic in 47 (83.6%) and extrapelvic in eight (14.5%). We found associated abnormalities of the upper urinary tract in six patients (solitary kidney in four and ptosis in two). CONCLUSIONS MRI is a useful diagnostic tool in the preoperative evaluation of MRKH syndrome and is less expensive and invasive than laparoscopy. Strong cooperation between radiologists and surgeons is highly recommended.

Abstract
OBJECTIVE To detect a direct transition from a haemorrhagic corpus luteum to an endometriotic cyst by serial transvaginal ultrasonographic scans. DESIGN Prospective observational study. SETTING An academic tertiary care and referral centre for women with endometriosis. POPULATION One hundred and nine women younger than 40 years, with regular menstrual cycles, undergoing first-line surgery for endometriomas, and not wanting postoperative oral contraception. METHODS Three-monthly transvaginal ultrasonography during the luteal phase for 2 years after surgery. MAIN OUTCOME MEASURE Sonographic identification of progression from a haemorrhagic corpus luteum to a recurrent endometriotic cyst. RESULTS A haemorrhagic corpus luteum was identified in 13 women. Serial ultrasonographic scans demonstrated transition to an endometriotic cyst in 11 (85%) instances and resorption in two. A unilateral endometriotic cyst without previous detection of a cystic corpus luteum was observed in 14 women. CONCLUSIONS Bleeding from a corpus luteum appears to be a critical event in the development of endometriomas.

Abstract
BACKGROUND The hormonal milieu that characterizes pregnancy may determine profound modifications of ovarian endometriomas leading to lesions mimicking malignancy. In this study, we report on our experience and perform a review of the literature on this issue. METHODS Data from women evaluated at our referral center for prenatal diagnosis were reviewed in order to identify those who were detected with an ovarian endometrioma in pregnancy mimicking malignancy. A review of the literature on this issue (1990-2008) was also performed, using the PubMed database. RESULTS Three cases were identified at our center. The literature reports on a further 19 cases (11 studies). Sonographic and color Doppler examination consistently documented rapidly growing and abundantly vascularized intracystic excrescences. Conversely, the presence of septations or significant free fluid was never reported. The vast majority of cases underwent surgical removal. Interestingly, in our experience, in a woman who declined surgery and had spontaneous miscarriage at 10 weeks' gestation, the sonographic examination performed 6 weeks after dilatation and curettage revealed an unremarkable typical endometrioma, thus suggesting that it is a transitory transformation. CONCLUSIONS Pregnancy-related modifications of an ovarian endometrioma leading to the rapid development of vascularized intracystic excrescences are an uncommon but possible event. An expectant management and serial monitoring should first be envisaged in these cases provided that other features of malignancy, such as septations or free fluid, are absent.

Abstract
Several causes of chronic pelvic pain (CPP) are recognised, but in many women a definite diagnosis cannot be made. Few randomised controlled trials on treatment of CPP have been conducted. In a Cochrane systematic review, only medroxy-progesterone acetate, counselling, a multidisciplinary approach and lysis of deep adhesions had a proven benefit. The aim of this descriptive review is to describe the management of CPP, which can focus on treating the pain itself, the underlying cause, or both. Combination drug therapy with medications with different mechanisms of action may improve therapeutic results. Pelvic denervating procedures should be indicated in selected circumstances, as the magnitude of the effect is undefined. Several alternative non-invasive treatments have been proposed including exercise programmes, cognitive and behavioural medicine, physical therapy, dietary modification, massage and acupuncture. When the woman has completed her family and particularly when pelvic varices have been demonstrated, hysterectomy can be considered after a careful pre-operative assessment. However, substantial pain relief may be achieved in no more than 60-70% of the cases. A minority of patients (3-5%) will experience worsening of pain or will develop new symptoms after surgery. Treatment of CPP, generally, requires acceptance of the concept of managing rather than curing symptoms.

Abstract
Chronic pelvic pain (CPP), defined as non-cyclic pain of 6 or more months, is a frequent disorder that may negatively affect health-related quality of life. In women several causes are recognised, although in a not negligible proportion of patients a definite diagnosis cannot be made. Different neurophysiological mechanisms are involved in the pathophysiology of CPP. Pain may be classified as nociceptive or non-nociceptive. In the first case the symptom originates from stimulation of a pain-sensitive structure, whereas in the second pain is considered neuropatic or psychogenic. Patients history is crucial and is generally of utmost importance for a correct diagnosis, being sometimes more indicative than several diagnostic investigations. The main contributing factors in women with CPP can still be identified by history and physical examination in most cases. Many disorders of the reproductive tract, urological organs, gastrointestinal, musculoskeletal and psycho-neurological systems may be associated with CPP. Excluding endometriosis, the most frequent causes of CPP are: post-operative adhesions, pelvic varices, interstitial cystitis and irritable bowel syndrome. CPP is a symptom, not a disease, and rarely reflects a single pathologic process. Gaining women's trust and developing a strong patient-physician relationship is of utmost importance for the long-term outcome of care.

Abstract
OBJECTIVE To describe two rare cases of multiple extrauterine adenomyomas, their clinical management, and their response to surgical and hormone therapy with GnRH agonist. DESIGN Case report and review of the English-language scientific literature. SETTING Cases presented in a tertiary health care academic institution. PATIENT(S) Two patients without urogenital malformations diagnosed with extrauterine adenomyoma, which is a benign tumor composed of smooth muscle and endometrium, typically originating within the uterus. INTERVENTION(S) Surgical radical excision of adenomyomas followed by a long-term hormone therapy with GnRH agonist. MAIN OUTCOME MEASURE(S) Anatomical and clinical outcomes. RESULT(S) Surgical treatment followed by long-term GnRH agonist therapy appeared effective in keeping the disease stable. After a long-term follow-up of 10 and 4 years, the two patients are still asymptomatic and stable. CONCLUSION(S) Only 19 other cases of extrauterine adenomyomas are reported in the English-language scientific literature, and no cases of multiple masses are described until now. It is probable that these extrauterine adenomyomas arose from a metaplastic transformation of the subcelomic mesenchyme. Long-term GnRH agonist therapy after surgery appeared effective in keeping the disease stable.

Abstract
BACKGROUND Surgery is often considered the best treatment option in women with symptomatic endometriosis. However, extent and duration of the therapeutic benefit are still poorly defined. METHODS The best available evidence on surgery for endometriosis-associated pain has been reviewed to estimate the effect size of interventions in the most frequently encountered clinical conditions. RESULTS Methodological drawbacks limit considerably the validity of observational, non-comparative studies on the effect of laparoscopy for stage I-IV disease. As indicated by the results of three RCTs, the absolute benefit increase of destruction of lesions compared with diagnostic only operation in terms of proportion of women reporting pain relief was between 30% and 40% after short follow-up periods. The effect size tended to decrease with time and the re-operation rate, based on long-term follow-up studies, was as high as 50%. In most case series on excisional surgery for rectovaginal endometriosis, substantial short-term pain relief was experienced by approximately 70-80% of the subjects who continued the study. However, at 1 year follow-up, approximately 50% of the women needed analgesics or hormonal treatments. Major complications were observed in 3-10% of the patients. Medium-term recurrence of lesions was observed in approximately 20% of the cases, and around 25% of the women underwent repetitive surgery. CONCLUSIONS Pain recurrence and re-operation rates after conservative surgery for symptomatic endometriosis are high and probably underestimated. Clinicians and patients should be aware that the expected benefit is operator-dependent.

Abstract
Endometriosis is a common and enigmatic disease causing pelvic pain and infertility. Current treatment is mainly based on the use of surgery and ovarian suppressive agents. There is in particular the need for new therapeutic options able to allow a normal menstrual cycle to occur and also consent pregnancy. In the present review, we aimed to give a concise and practical overview in order to allow the clinician to clearly understand the level of development of these drugs. We have presented only treatments supported by in vivo researches with a special attention to studies in humans. Results show appealing new possibilities are emerging from agents counteracting the endometriosis-associated inflammation. Recent data also suggests that there is still the opportunity to refine the use of already available agents.

PATIENT(S) Thirteen patients with deep endometriosis and ureteral involvement. Mean age of patients was 36.8 years (range, 31-48 years). INTERVENTION(S) Ureteroneocystostomy with a psoas hitch. Indications for performing psoas hitch ureteroneocystostomy were severe hydronephrosis, radiologic evidence of ureteral stricture measuring >4 cm, and the impossibility of performing ureterolysis. MAIN OUTCOME MEASURE(S) Impact on urodynamic parameters of bladder psoas hitch ureteroneocystostomy. RESULT(S) All patients showed normal bladder capacity 3 months after surgery. Two patients presented with stress incontinence immediately after surgery, which almost completely subsided at 3 months' follow-up. In 4 patients the bladder was also involved; in these cases a bladder resection was performed, followed by ureteral reimplantation. Follow-up was at 6 months from surgery and then every 6 months thereafter, in which patients underwent urogynecologic examination, completed a questionnaire on urinary symptoms, and underwent renal ultrasound evaluation with no evidence of recurrence of obstructive uropathy. CONCLUSION(S) On the basis of the results of the present study, bladder psoas hitch along with ureteral resection and ureteroneocystostomy for infiltrating endometriosis do not seem to have a negative impact on urodynamic parameters.

Abstract
Like endometriosis and uterine myomas, adenomyosis presents the typical characteristics of oestrogen-dependent diseases. The medical treatment of adenomyosis is based on the hormonal dependency of the disease and its strongly debated similarities with endometriosis. Infact, despite the evident differences between the two conditions, the therapies that treat endometriosis effectively have also been successful for the treatment of adenomyosis. Although the two diseases have distinct epidemiological features, they have the same 'target tissue' for hormonal therapy, namely ectopic endometrium. Recognized approaches are systemic hormonal treatments, which are generally used for endometriosis and are capable of suppressing the oestrogenic induction of the disease, and local hormonal treatment that targets the ectopic endometrium directly. Gonadotropin-releasing hormone agonists, danazol and intrauterine levonorgestrel- or danazol-releasing devices have been used in the treatment of adenomyosis. Despite the solid rational basis for its hormonal treatment, few studies have been performed on medical therapy for adenomyosis.

Abstract
Gene polymorphisms, in particular single nucleotide polymorphisms (SNPs), have been associated to multifactorial diseases such as cancer, inflammation and autoimmunity. Indeed for some autoimmune diseases, it has been possible to identify critical residues that play a major role in susceptibility to diseases. The association of a common T/C polymorphism in the promoter region of the beta 2 constant chain of the T-cell receptor with autoimmune diseases, such as insulin-dependent diabetes, autoimmune hepatitis, IgA nephropathy, membranous nephropathy, Graves' disease and Hashimoto's thyroiditis, was described in the 1990 s. These reports have not been confirmed in the last few years. We also failed in a previous study to detect any difference between 70 normal subjects and 70 patients with primary biliary cirrhosis; however, we found a difference in allelic frequency between males and females. This finding led us to make an allele frequency study of this single nucleotide polymorphism between sexes in a new series of patients. We studied 165 subjects, 80 males and 85 females, and we found a significant difference between sexes especially for the CC homozygous genotype: 34% of females vs. 14% of males (P = 0.008). If the higher frequency of CC homozygous genotype (that is associated with an increased risk of autoimmune diseases) in females would be confirmed in normal population, this could be an explanation of the controversial results obtained by association studies made between this SNP and autoimmune diseases.

Abstract
OBJECTIVE To describe the surgical technique and the long-term anatomic and functional results of laparoscopically assisted uterovestibular anastomosis. DESIGN Descriptive study. SETTING Tertiary referral center. PATIENT(S) Twelve consecutive patients with uterine cervix atresia and vaginal aplasia. INTERVENTION(S) Laparoscopically assisted uterovestibular anastomosis was performed in all patients. Follow-up assessments at 1, 6, and 12 months included pelvic examination, transvaginal ultrasonography, and, in selected cases, vaginoscopy and hysteroscopy. Subsequent follow up was done by referring physicians or by means of telephone interview. Mean follow-up was 6 years. MAIN OUTCOME MEASURE(S) Intra- and postoperative characteristics and anatomic and functional outcome. RESULT(S) The surgical procedure was successful in all cases and all of the women have experienced regular menstruation. At 6-month follow-up, mean vaginal length was 6 cm and at least 80% of neovaginal epithelium was iodine-positive in all patients. Six women were sexually active during follow-up without difficulty. None have yet attempted to seek a pregnancy. CONCLUSION(S) The study shows the safety and effectiveness of a laparoscopic approach to uterovestibular anastomosis in women with cervical atresia and vaginal aplasia. In these patients, we believe that conservative surgery should represent the first therapeutic option. A longer follow-up is needed to assess pregnancy rates and outcome.
