OBJECTIVE: The purpose of this study was to define the incidence of deep venous thrombosis (DVT) and pulmonary embolism (PE) in patients with clear cell carcinoma (CCC) of the ovary and to investigate the prognostic factors in such patients. METHODS: Between January 1987 and December 2003, 641 women with primary invasive epithelial ovarian cancer underwent treatment at the Royal Hospital for Women in Sydney, Australia. Sixty-six patients (10.3%) with CCC were identified from the data bank, and their data were compared with a matched-control group of 132 patients with non-clear cell epithelial ovarian carcinoma. RESULTS: A thromboembolic event (DVT or PE) was noted in 27.3% of patients with CCC, compared to 6.8% of patients with other epithelial ovarian cancers. PE was detected in 13.6% and 3.8% of patients, respectively. In patients with CCC, DVT was frequently observed before operation or at the time of recurrence. In a multivariate analysis of patients matched for age and stage, the occurrence of a DVT or the presence of endometriosis was significant predictors of clear cell histology. Within the clear cell group, no particular risk factor for DVT could be identified. Metastases of 50 mm or greater in diameter, ascites of 1000 ml or more, advanced FIGO stage, and the occurrence of DVT were poor prognostic factors for CCC in univariate analysis, but in a multivariate Cox regression analysis, only FIGO stage and occurrence of DVT remained significant. CONCLUSION: The incidence of venous thromboembolic events was found to be significantly higher in patients with CCC when compared to patients with other epithelial ovarian cancers.

Evidence as to whether clinician has to give specific treatment in all patients of catamenial hemoptysis is unclear. We considered that the current treatment such as long-term usage of hormonal agent or surgery might be excessive for the catamenial hemoptysis. Therefore, we developed prospective observation study with observation strategy and follow-up for the patients. In sequential four patients of catamenial hemoptysis between December 2000 and November 2001, physical examination, chest X-ray, pelvic ultrasonogram and chest CT scan were taken at both the diagnosis and last follow-up. All patients were only observed without specific treatment within the limit of the possibility and followed for average 58 months. Mean age of patients was 23.5years (range, 22-25years). All patients have a history of undertaking one or two dilatations and curettages before diagnosis. The chest CT scans of all patients presented with ground-glass opacities of peripheral location that were disappeared without any residual lesion at last follow-up. Hemoptysis of two patients was spontaneously disappeared after 6 months. In the other two patients, it was greatly lessened in amount and frequency, then clinically insignificant in one. It was disappeared after subsequent 2 months and then relapsed two times in the late of follow-up of another patient. This study suggests that observation only may be an alternative option in the treatment of catamenial hemoptysis.

BACKGROUND: Deep infiltrating endometriosis (DIE) is commonly associated with severe pain. The pain can be managed successfully with GnRH agonists or continuous progestins. The precise molecular mechanism by which DIE causes pain or why hormonal treatment is effective, however, remains unclear. We recently identified three potential candidate genes that might be involved in DIE pain pathways: tyrosine kinase receptor B (TrKB), mu-opioid receptor (MOR) and serotonin transporter (5HTT). We hypothesized that if these three genes were involved in DIE-associated pain, their expression levels would probably be modulated by GnRH agonist or progestin. In this study, we compared mRNA expression levels of TrKB, MOR and 5HTT in DIE among patients pre-operatively treated with GnRH agonist, progestin or without pre-operative medical treatments. METHODS: The expression levels of TrKB, MOR and 5HTT mRNA in DIE were determined using laser capture microdissection and real-time RT-PCR techniques. RESULTS: The expression levels of TrKB in epithelial cells and MOR in stromal cells from DIE were significantly decreased in patients with pre-operative GnRH agonist or progestin. There was no significant difference in 5HTT expression levels among untreated, GnRH agonist- and progestin-treated patients. CONCLUSION: The expression levels of TrKB and MOR genes in DIE appeared to be modulated by GnRH agonist or progestin. However, the functional roles of TrKB and MOR in DIE remain to be clarified.

OBJECTIVE: To assess the effect of a new progestin progestogen only pill (desogestrel) versus an oral contraceptive in the treatment of recurrent endometriosis. STUDY DESIGN: A randomized prospective clinical study. A group of women with endometriosis (n=40) who showed recurrent dysmenorrhea and/or pelvic pain after conservative surgery, and did not desire a pregnancy. Continuous treatment for 6 months with desogestrel (75 microg/d) (n=20) versus a combined oral contraceptive (ethinyl estradiol 20 microg plus desogestrel 150 microg) (n=20) was performed. RESULTS: A significant improvement of both pelvic pain and dysmenorrhea was observed following each type of treatment (P<0.001). The use of desogestrel progestogen only pill was associated with a breakthrough bleeding in 20% patients, while a significant body weight increase was observed in 15% after oral contraceptive. CONCLUSIONS: Both desogestrel and an oral estro-progestinic were effective, safe and low cost therapy of pain symptoms after endoscopic surgery for endometriosis, the former showing an impact on breakthrough bleeding, the later an incidence on body weight increase.

Uterine stem cells: what is the evidence?

Gargett CE.

Department of Obstetrics and Gynaecology, Monash University, Melbourne, Victoria, Australia. caroline.gargett@med.monash.edu.au

The mucosal lining (endometrium) of the human uterus undergoes cyclical processes of regeneration, differentiation and shedding as part of the menstrual cycle. Endometrial regeneration also follows parturition, almost complete resection and in post-menopausal women taking estrogen replacement therapy. In non-menstruating species, there are cycles of endometrial growth and apoptosis rather than physical shedding. The concept that endometrial stem/progenitor cells are responsible for the remarkable regenerative capacity of endometrium was proposed many years ago. However, attempts to isolate, characterize and locate endometrial stem cells have only been undertaken in the last few years as experimental approaches to identify adult stem/progenitor cells in other tissues have been developed. Adult stem cells are defined by their functional properties rather than by marker expression. Evidence for the existence of adult stem/progenitor cells in human and mouse endometrium is now emerging because functional stem cell assays are being applied to uterine cells and tissues. These fundamental studies on endometrial stem/progenitor cells will provide new insights into the pathophysiology of various gynaecological disorders associated with abnormal endometrial proliferation, including endometrial cancer, endometrial hyperplasia, endometriosis and adenomyosis.

Endometriosis involving the ileocaecal junction with regional lymph node involvement in the baboon–striking pathological finding identical between the human and the baboon: a case report.

The baboon is an established model for endometriosis research. This report describes the occurrence of spontaneous endometriosis involving the ileocaecal junction and associated regional lymph nodes in the baboon. All endometriotic foci lacked the nuclear atypia, abnormal mitotic activity and altered nuclear-to-cytoplasmic ratio typical of malignancy. These findings are identical to reports in the human in which ileocaecal and colonic endometriosis is associated with endometriosis in pericolonic and mesenteric lymph nodes. The similarity between baboon and human colonic endometriosis in both location and pathology is striking and lends further evidence supporting the validity of the baboon as a model for human endometriosis.

This prospective study aims to evaluate the efficacy of multislice computed tomography combined with colon distension by water enteroclysis (MSCTe) in determining the presence and depth of bowel endometriotic lesions. Ninety-eight women with symptoms suggestive of colorectal endometriosis underwent MSCTe; locations, number of nodule/s, size of the nodule/s and depth of bowel wall infiltration were determined. Independently from the findings of MSCTe, all women underwent laparoscopy. MSCTe findings were compared with surgical and histological results. Abnormal findings suggestive of bowel endometriotic nodules were detected by MSCTe in 75 of the 76 patients with bowel endometriosis. MSCTe identified 110 (94.8%) of the 116 bowel endometriotic nodules removed at surgery; 6 nodules missed at MSCTe were located on the rectum. MSCTe correctly determined the degree of infiltration of the bowel wall in all of the 34 serosal bowel nodules identified at MSCTe. In six nodules reaching the submucosa, the depth of infiltration was underestimated by MSCTe. MSCTe had a sensitivity of 98.7%, a specificity of 100%, a positive predictive value of 100% and a negative predictive value of 95.7% in identifying women with bowel endometriosis. MSCTe is effective in determining the presence and depth of bowel endometriotic lesions.

BACKGROUND: The association between lesion type, disease stage and severity of pain was studied in a large group of women with endometriosis to verify whether endometrial implants at different sites determine specific complaints and to evaluate the validity of the current classification system in women with symptomatic disease. METHODS: A total of 1054 consecutive women with endometriosis undergoing first-line conservative or definitive surgery were included. Data on age at surgery, disease stage according to the revised American Fertility Society (AFS) classification, anatomical characteristics of endometriotic lesions, and type and severity of pain symptoms were collected and analysed by multiple logistic regression. RESULTS: Minimal endometriosis was present in 319 patients, mild in 139, moderate in 292 and severe in 304. A significant inverse relationship was demonstrated between age at surgery and moderate-to-severe dysmenorrhoea, dyspareunia and non-menstrual pain. A strong association was found between posterior cul-de-sac lesions and pain at intercourse [Wald chi (2) = 17.00, P = 0.0001; odds ratio (OR) = 2.64, 95% confidence interval (CI) = 1.68-4.24]. A correlation between endometriosis stage and severity of symptoms was observed only for dysmenorrhoea (Wald chi (2) = 5.14, P = 0.02) and non-menstrual pain (Wald chi (2) = 5.63, P = 0.018). However, the point estimates of ORs were very close to unity (respectively, 1.33, 95% CI = 1.04-1.71, and 1.01, 95% CI = 1.00-1.03). CONCLUSIONS: The association between endometriosis stage and severity of pelvic symptoms was marginal and inconsistent and could be demonstrated only with a major increase in study power.

BACKGROUND: Alterations in the progesterone receptor (PR) are considered a risk factor for the development of endometriosis. In this study, the frequencies of the PROGINS and +331G/A polymorphisms of the PR gene were determined in deep infiltrating endometriosis and correlated with the expression of the PR protein. METHODS AND RESULTS: The frequencies of the PR polymorphisms were determined in women with deep infiltrating endometriosis (n = 72), women with adenomyosis in the uterine wall (n = 40), gynaecological patients without symptomatic endometriosis (n = 102) and healthy females (n = 93). Detection of +331G/A and PROGINS polymorphisms was performed using PCR-restriction fragment length polymorphism (RFLP) analysis. Expression of PR-A and PR-B protein was assessed with immunohistochemistry. The allelic frequency of the polymorphic allele +331A was lower in women with endometriosis (P < 0.01) and adenomyosis (P < 0.02) compared with healthy females. The frequency of the PROGINS polymorphism did not differ between the groups. The mean staining index (SI) for PR-B in endometriotic epithelium was higher in the presence of the +331A polymorphic allele (n = 2) (P < 0.001) compared with +331G/G individuals (n = 61). The PROGINS polymorphism did not affect the SI for PR-A and PR-B. CONCLUSIONS: The presence of the PR gene polymorphic allele +331A is associated with a reduced risk of deep infiltrating endometriosis and adenomyosis compared with healthy population controls. The PROGINS polymorphism does not seem to modify the risk of deep infiltrating endometriosis.

Most of the current medical treatments for endometriosis aim to downregulate estrogen activity. However, a high recurrence rate after medical treatment has been the most significant problem. BAY 11-7085, a soluble inhibitor of NK-kappaB activation, has been shown to inhibit cell proliferation and induce apoptosis of a variety of cells. To examine the potential application of BAY 11-7085 in the treatment of endometriosis, we investigated the effects of this agent on the cell proliferation and apoptosis of cultured ovarian endometriotic cyst stromal cells (ECSCs) by a modified methylthiazole tetrazolium assay, a 5-bromo-2′-deoxyuridine incorporation assay, and internucleosomal DNA fragmentation assays. The effect of BAY 11-7085 on the cell cycle of ECSCs was also determined by flow cytometry. The expression of apoptosis-related molecules was examined in ECSCs with Western blot analysis. BAY 11-7085 significantly inhibited the cell proliferation and DNA synthesis of ECSCs and induced apoptosis and the G0/G1 phase cell cycle arrest of these cells. Additionally, downregulation of the B-cell lymphoma/leukemia-2 (Bcl-2) and Bcl-X(L) expression with simultaneous activation of caspase-3, -8, and -9 was observed in ECSCs after treatment with BAY 11-7085. These results suggest that BAY 11-7085 induces apoptosis of ECSCs by suppressing antiapoptotic proteins, and that caspase-3-, -8-, and -9-mediated cascades are involved in this mechanism. Therefore, BAY 11-7085 could be used as a therapeutic agent for the treatment of endometriosis.

OBJECTIVE: Chronic pelvic pain is a complex disease and is far more common than generally recognized. STUDY DESIGN: Between 1 January 1979 and 31 December 2002 authors had performed 11,681 laparoscopic interventions. Among them, 1061 operations (9.08%) were done because of chronic pelvic pain. RESULTS: In 29.5% of these cases no anatomical abnormality was found. Analysis of data of laparoscopic operations performed from 1989 to 1990 and from 1998 to 1999 revealed that complaints dated back for a significantly longer period of time in patients presenting no obvious sign of pelvic anatomical anomaly when compared with those who had positive findings. In patients with positive pelvic findings laparotomy had previously been performed in a significantly higher number. When no apparent pelvic pathology was found medical history was also negative for ectopic pregnancy. Similarly, there were only three cases of previous adnexal operations. However, among patients with positive findings, medical history revealed 19 prior cases of ectopic pregnancy, 49 cases of previous adnexal operations, 82 appendectomy, and 26 cholecystectomy (p<0.01). Among patients with positive pelvic findings, diagnostic laparoscopy was immediately completed by adequate surgical treatment in the same session in more than two-third of cases. Most frequently this included adhesiolysis, ovarian cystectomy, uterosacral nerve ablation, electrocoagulation of areas of endometriosis, and ventrosuspension of the retroflected uterus. CONCLUSION: Based on our retrospective data analysis we believe that laparoscopy is an essential method for the diagnosis and management of chronic pelvic pain.

OBJECTIVE: We present a retrospective analysis of 22 cases of endometrioid ovarian carcinoma, reviewed to identify endometriosis and its malignant transformation. STUDY DESIGN: Twenty-two patients with endometrioid ovarian cancer were included in the review. Their clinical and histological data were retrospectively reviewed. The origin of the tumours was considered endometriosis-related when the presence of malignant changes in endometriosis glands leading to endometrioid carcinoma were found. RESULTS: Endometriosis was detected in three cases (3/22=14%). One of them presented a clearly benign to malignant transformation area. In another patient, the transition zone was abrupt and present in both ovaries. In the third, a pre-menopausal woman, ovarian endometriosis with only focal endometrioid carcinoma was observed. The three of them had a clear-cell carcinoma component. The presence of a clear-cell component was significantly greater in patients with endometriosis than in patients without endometriosis Each patient had a different clinical presentation: increase in abdominal perimeter, post-menopausal vaginal haemorrhage and hypermenorrhea. Preoperative CA 125 levels were avalaible in 15 of the patients (15/22=68%). Endometriosis was found in two of these 15 patients, both with the highest CA 125 measured levels, exceeding 1700 U/ml. In the remaining of the patients, CA 125 value did not exceed 35 U/ml. CONCLUSION: Although this association is not very frequent, patients with ovarian endometriosis and a high CA 125 serum level should be managed with special care, regardless of their pre-menopausal or post-menopausal status.

Human Locomotion Science, University of Southern Denmark, Odense, Denmark.

Some chronic painful conditions including e.g. fibromyalgia, whiplash associated disorders, endometriosis, and irritable bowel syndrome are associated with generalized musculoskeletal hyperalgesia. The aim of the present study was to determine whether generalized deep-tissue hyperalgesia could be demonstrated in a group of patients with chronic low-back pain with intervertebral disc herniation. Twelve patients with MRI confirmed lumbar intervertebral disc herniation and 12 age and sex matched controls were included. Subjects were exposed to quantitative nociceptive stimuli to the infraspinatus and anterior tibialis muscles. Mechanical pressure (thresholds and supra-threshold) and injection of hypertonic saline (pain intensity, duration, distribution) were used. Pain intensity to experimental stimuli was assessed on a visual analogue scale (VAS). Patients demonstrated significantly higher pain intensity (VAS), duration, and larger areas of pain referral following saline injection in both infraspinatus and tibialis anterior. The patients rated significantly higher pain intensity to supra-threshold mechanical pressure stimulation in both muscles. In patients, the pressure pain-threshold was lower in the anterior tibialis muscle compared to controls. In conclusion, generalized deep-tissue hyperalgesia was demonstrated in chronic low-back pain patients with radiating pain and MRI confirmed intervertebral disc herniation, suggesting that this central sensitization should also be addressed in the pain management regimes.

OBJECTIVES: This study was undertaken to evaluate the incidence and the factors associated with uterine bleeding while taking GnRH agonist treatment combined with tibolone add-back therapy in endometriosis patients of reproductive age. STUDY DESIGN: The medical records of 188 endometriosis (stages III-IV) patients of reproductive age receiving postoperative GnRH agonist treatment combined with tibolone add-back therapy for 6 months were reviewed. Clinical features were analyzed and compared between the two groups: Group A, patients without an episode of uterine bleeding (n=137) and Group B, patients that had experienced uterine bleeding (n=51). RESULTS: Demographic profiles were not different in the two groups. The incidence of uterine bleeding was 27.1% and irregular spotting was the most frequent bleeding pattern. The proportion of patients who received ovarian surgery during pelviscopy was higher in Group B (p<0.05), but other clinical characteristics were not different between two groups. CONCLUSIONS: The incidence of uterine bleeding was 27.1%. And, the proportion of patients who received ovarian surgery was higher in patients with uterine bleeding.

Peritoneal endometriosis (PE) and deep endometriotic nodules (DEN) are gynecological diseases recently shown to be associated with elevated serum concentrations of organochlorines. The objective of the present study was to compare risk factors associated with both forms of the disease, with a particular attention to potential sources of organochlorine exposure. This matched case-control study with prospective recruitment included 88 triads (PE-DEN-control). All women were face-to-face interviewed with a standardized questionnaire, and serum dioxin and polychlorinated biphenyl measurements were available for 58 of them. Alcohol consumption (odds ratio (OR): 5.82 [confidence interval at 95% (95%CI) 1.20-28.3]) in DEN and low physical activity at work for DEN (OR: 4.58 [95%CI 1.80-11.62]) and PE (OR: 5.61 [95%CI 1.90-16.60]) were traced as significant risk factors. Organochlorine-related factors (use of tampons, occupational or environmental exposure) were not related to the disease. The current consumption of foodstuffs that were more likely to contribute to organochlorine body burden did not differ among the groups. Only some of these fatty foodstuffs (marine fish, pig meat) were traced by multiple regression analysis as significant determinants of organochlorine body burden, explaining only a small fraction (20%) of the interindividual variation of organochlorine body burden. We conclude that PE and DEN share similar patterns of risk or protective factors.

Department of Mother’s and Child’s Health, University of Medical Sciences, Polna 33, 60-535 Poznan, Poland. kp.szymanowski@wp.pl

OBJECTIVE: In the present study we aimed to describe apoptosis patterns in eutopic endometrium in women suffering from endometriosis in order to assess its value as a marker of early forms of endometriosis, and also to try to answer whether endometriosis is caused by changes within the eutopic endometrium or whether endometriotic lesions change the characteristics of eutopic endometrium. STUDY DESIGN: The study was performed on 125 women treated in Division of Reproduction. In 52 patients peritoneal endometriosis was diagnosed (I(0)-23; II(0)-29). Seventy-three patients in whom no endometriotic foci could be found at laparoscopy were qualified as the control group. Endometrial biopsy 7-9 days after ovulation was taken for assessment of apoptosis (TUNEL) and routine histology. RESULTS: Apoptosis indices in the eutopic endometrium of women with endometriosis were lower compared to women without endometriosis. In the endometrial glands apoptosis indices were 2.94+/-1.66 versus 5.23+/-2.06 (p<0.01) in the group of women with and without endometriosis, respectively. In the endometrial stroma apoptosis indices were estimated at 2.04+/-1.72 in women with endometriosis and 4.12+/-1.62 in the control group (p<0.01). CONCLUSIONS: The observed changes could support the hypothesis of the different properties of eutopic endometrium in endometriotic women as a causing factor of peritoneal endometriosis.

Department of Neurosciences, Ophthalmology and Genetics, University of Genoa, and Department of Obstetrics and Gynaecology, San Martino Hospital, Genoa, Italy.

OBJECTIVE: This study aims to determine whether women with endometriosis have greater subclinical atherosclerosis than the general population. STUDY DESIGN: This case-control study included 66 women with endometriosis and 66 controls matched for age and body mass index. All subjects were >or=35 years old. Exclusion criteria were obesity, diabetes, hypertension, hyperlipidemia, renal or metabolic diseases. Before laparoscopy, all patients underwent a measurement of intima-media thickness (IMT) and distensibility coefficient (DC) on the common carotid artery. In addition, blood samples were taken to determine the levels of lipids, fibrinogen, C-reactive protein, homocysteine, fasting glycemia, antithrombin III, plasminogen, protein C, protein S, and activated protein C resistance. RESULTS: All the biochemical parameters evaluated had similar levels in the two study groups. IMT was similar in women with endometriosis and in controls both on left (p=0.330) and right (p=0.648) carotid artery. Similarly, no significant difference was observed in the DC between women with endometriosis and controls both on left (p=0.539) and right (p=0.178) carotid artery. No significant difference was observed in IMT and DC between women with mild and severe endometriosis. CONCLUSION: Women with endometriosis do not have more subclinical atherosclerosis than the general population.

1st Department of Gynecology, University School of Medicine, Lublin, Poland. polakg@yahoo.com <polakg@yahoo.com>

OBJECTIVE: The aim of the study was to evaluate for the presence of lactoferrin (LTF) in peritoneal fluid (PF) of women with and without endometriosis. PATIENTS: Seventy-eight women were studied, including 49 women with endometriosis and, as a reference group, 29 patients with functional follicle ovarian cysts. RESULTS: Lactoferrin levels were detectable in all peritoneal fluid samples. Women with minimal endometriosis had lower PF lactoferrin concentrations compared to both patients with high revised American Fertility Society classification scores and women with follicle ovarian cysts. No significant difference in the peritoneal LTF levels was found between patients with stage II endometriosis, stage III or IV endometriotic disease and women with functional cysts of ovaries. CONCLUSIONS: Owing to its antibacterial properties lactoferrin is probably an important defense factor in the peritoneal cavity, however its role in the pathogenesis of endometriosis remains enigmatic.

Vesical endometriosis accounts for approximately 1% of all discovered cases of endometriosis. We report the first case of a 36-year-old woman with pregnancy-associated decidual changes within bladder endometriosis that are clinically presented as a rapidly growing bladder tumor. Cystoscopy, with subsequent cold cup biopsy and fulguration, revealed a solitary, red-brown, nodular lesion, which turned to be a decidualized endometriosis of the urinary bladder. Delivery and postdelivery follow-up was uneventful and no recurrence was diagnosed.

The unexpected discovery of a second form of the estrogen receptor (ER), designated ERbeta, surprised and energized the field of estrogen research. In the 9 yr since its identification, the remarkable efforts from academic and industrial scientists of many disciplines have made significant progress in elucidating its biology. A powerful battery of tools, including knockout mice as well as a panel of receptor-selective agonists, has allowed an investigation into the role of ERbeta. To date, in vivo efficacy studies are limited to rodents. Current data indicate that ERbeta plays a minor role in mediating estrogen action in the uterus, on the hypothalamus/pituitary, the skeleton, and other classic estrogen target tissues. However, a clear role for ERbeta has been established in the ovary, cardiovascular system, and brain as well as in several animal models of inflammation including arthritis, endometriosis, inflammatory bowel disease, and sepsis. The next phase of research will focus on elucidating, at a molecular level, how ERbeta exerts these diverse effects and exploring the clinical utility of ERbeta-selective agonists.

OBJECTIVE: Ovarian endometrioma recurrence is frequent. Conventional treatment of ovarian endometrioma is by surgical cystectomy. We proposed an alternative medical treatment for recurrent ovarian endometrioma: cyst aspiration followed by in situ methotrexate injection. STUDY DESIGN: From January 2002 to May 2003, 14 patients with recurrent homolateral ovarian endometrioma underwent transvaginal ultrasound guided cyst puncture and aspiration followed by methotrexate injection, whilst under general anasthesia. Recurrence rate during follow up was evaluated. RESULTS: No complication was reported. After a mean follow up of 20+/-5 month (min: 13, max: 29), four recurrences were diagnosed (28.6%). Two asymptomatic recurrences were not treated and two painful recurrences underwent a second cyst drainage with methotrexate injection. CONCLUSIONS: In situ methotrexate injection is a simple, effective and an interesting alternative to surgical treatment in women with recurrent homolateral ovarian endometrioma.
