Endometriosis is a risk factor for recurrent pelvic inflammatory disease after tubo-ovarian abscess surgery.

PURPOSE: To evaluate the clinical outcomes and prognosis of patients undergoing laparoscopic surgery for tubo-ovarian abscess (TOA) and identify risk factors for pelvic inflammatory disease (PID) recurrence. METHODS: We conducted a retrospective cohort analysis including 98 women who underwent laparoscopic surgery for TOA at the Department of Obstetrics and Gynecology at the Bern University Hospital from January 2011 to May 2021. The primary outcome studied was the recurrence of PID after TOA surgery. Clinical, laboratory, imaging, and surgical outcomes were examined as possible risk factors for PID recurrence. RESULTS: Out of the 98 patients included in the study, 21 (21.4%) presented at least one PID recurrence after surgery. In the univariate regression analysis, the presence of endometriosis, ovarian endometrioma, and the isolation of E. coli in the microbiology cultures correlated with PID recurrence. However, only endometriosis was identified as an independent risk factor in the multivariate analysis (OR (95% CI): 9.62 (1.931, 47.924), p < 0.01). With regard to the time of recurrence after surgery, two distinct recurrence clusters were observed. All patients with early recurrence (≤ 45 days after TOA surgery) were cured after 1 or 2 additional interventions, whereas 40% of the patients with late recurrence (> 45 days after TOA surgery) required 3 or more additional interventions until cured. CONCLUSION: Endometriosis is a significant risk factor for PID recurrence after TOA surgery. Optimized therapeutic strategies such as closer postsurgical follow-up as well as longer antibiotic and hormonal therapy should be assessed in further studies in this specific patient population.

Time to first recurrence, pattern of recurrence, and survival after recurrence in endometrial cancer according to the molecular classification.

OBJECTIVE: Despite its generally favorable prognosis at primary diagnosis, recurrence of endometrial cancer remains an important clinical challenge. The aim of this study was to analyze the value of molecular classification in recurrent endometrial cancer. METHODS: This study included patients with recurrent endometrial cancer who underwent primary surgical treatment between 2004 and 2015 at the Karolinska University Hospital, Sweden and the Bern University Hospital, Switzerland (KImBer cohort) with molecular classification of the primary tumor. RESULTS: Out of 594 molecularly classified endometrial cancer patients, 101 patients experienced recurrence, consisting of 2 POLEmut, 33 MMRd, 30 p53abn, and 36 NSMP tumors. Mean age at recurrence was 71 years and mean follow-up was 54 months. Overall, median time to first recurrence was 16 months (95% CI 12-20); with the shortest median time in MMRd patients, with 13 months (95% CI 5-21). The pattern of recurrence was distinct among molecular subgroups: MMRd tumors experienced more locoregional, while p53abn cases showed more abdominal recurrences (P = .042). Median survival after recurrence was best for MMRd cases (43 months, 95% CI 11-76), compared to 39 months (95% CI 21-57) and 10 months (95% CI 7-13) for the NSMP and p53abn cases respectively (log-rank, P = .001). CONCLUSION: Molecular classification is a significant indicator of survival after recurrence in endometrial cancer patients, and patterns of recurrence differ by molecular subgroups. While MMRd endometrial cancer show more locoregional recurrence and the best survival rates after recurrence, p53abn patients experience abdominal recurrence more often and had the worst prognosis of all recurrent patients.

Intrafollicular inflammatory cytokines but not steroid hormone concentrations are increased in naturally matured follicles of women with proven endometriosis.

PURPOSE: The aim of this study was to assess whether the intrafollicular cytokine profile in naturally developed follicles is different in women with endometriosis, possibly explaining the lower reproductive outcome in endometriosis patients. METHODS: A matched case-control study was conducted at a university-based infertility and endometriosis centre. The study population included 17 patients with laparoscopically and histologically confirmed endometriosis (rAFS stages II-IV), each undergoing one natural cycle IVF (NC-IVF) treatment cycle between 2013 and 2015, and 17 age-matched NC-IVF women without diagnosed endometriosis (control group). Follicular fluid and serum was collected at the time of follicle aspiration. The concentrations of inflammatory cytokines (IL-1ß, IL-6, IL-8, IL-15, IL-18, TNF-α) and hormones (testosterone, estradiol, AMH) were determined in follicular fluid and serum by single or multiplexed immunoassay and compared between both groups. RESULTS: In the follicular fluid, IL-1ß and IL-6 showed significantly (P < 0.001 and 0.01, respectively) higher median concentrations in the endometriosis group than in the control group and a tendency towards endometriosis severity (rAFS stage) dependence. The levels of the interleukins detectable in follicular fluid were significantly higher than those in the serum (P < 0.01). Follicular estradiol concentration was lower in severe endometriosis patients than in the control group (P = 0.036). Follicular fluid IL-1ß and IL-6 levels were not correlated with estradiol in the same compartment in neither patient group. CONCLUSIONS: In women with moderate and severe endometrioses, some intrafollicular inflammatory cytokines are upregulated and not correlated with intrafollicular hormone concentrations. This might be due to the inflammatory microenvironment in endometriosis women, affecting follicular function and thereby possibly contributing to the reproductive dysfunction in endometriosis.

Minimally invasive surgery when treating endometriosis has a positive effect on health and on quality of work life of affected women.

STUDY QUESTION: What is the effect of the minimally invasive surgical treatment of endometriosis on health and on quality of work life (e.g. working performance) of affected women? SUMMARY ANSWER: Absence from work, performance loss and the general negative impact of endometriosis on the job are reduced significantly by the laparoscopic surgery. WHAT IS KNOWN ALREADY: The benefits of surgery overall and of the laparoscopic method in particular for treating endometriosis have been described before. However, previous studies focus on medical benchmarks without including the patient's perspective in a quantitative manner. STUDY DESIGN, SIZE, DURATION: A retrospective questionnaire-based survey covering 211 women with endometriosis and a history of specific laparoscopic surgery in a Swiss university hospital, tertiary care center. Data were returned anonymously and were collected from the beginning of 2012 until March 2013. PARTICIPANTS/MATERIALS, SETTING, METHODS: Women diagnosed with endometriosis and with at least one specific laparoscopic surgery in the past were enrolled in the study. The study investigated the effect of the minimally invasive surgery on health and on quality of work life of affected women. Questions used were obtained from the World Endometriosis Research Foundation (WERF) Global Study on Women's Health (GSWH) instrument. The questionnaire was shortened and adapted for the purpose of the present study. MAIN RESULTS AND THE ROLE OF CHANCE: Of the 587 women invited to participate in the study, 232 (232/587 = 40%) returned the questionnaires. Twenty-one questionnaires were excluded due to incomplete data and 211 sets (211/587 = 36%) were included in the study. Our data show that 62% (n = 130) of the study population declared endometriosis as influencing the job during the period prior to surgery, compared with 28% after surgery (P < 0.001). The mean (maximal) absence from work due to endometriosis was reduced from 2.0 (4.9) to 0.5 (1.4) hours per week (P < 0.001). The mean (maximal) loss in working performance after the surgery averaged out at 5.7% (12.6%) compared with 17.5% (30.5%) before this treatment (P < 0.001). LIMITATIONS, REASONS FOR CAUTION: The mediocre response rate of the study weakens the representativeness of the investigated population. Considering the anonymous setting a non-responder investigation was not performed. A bias due to selection, information and negativity effects within a retrospective survey cannot be excluded, although study-sensitive questions were provided in multiple ways. The absence of a control group (sham group; e.g. patients undergoing specific diagnostic laparoscopy without treatment) is a further limitation of the study. WIDER IMPLICATIONS OF THE FINDINGS: Our study shows that indicated minimally invasive surgery has a clear positive effect on the wellbeing and working performance of women suffering from moderate to severe endometriosis. Furthermore, national net savings in indirect costs with the present number of surgeries is estimated to be €10.7 million per year. In an idealized setting (i.e. without any diagnosis delay) this figure could be more than doubled. STUDY FUNDING/COMPETING INTERESTS: The study was performed on behalf of the University Hospital of Bern (Inselspital) as one of the leading Swiss tertiary care centers. The authors do not declare any competing interests.

Clinical significance of 3D ultrasound compared to MRI in uterine malformations.

PURPOSE: Congenital uterine anomalies often remain asymptomatic until they cause problems, for example during pregnancy. We studied the diagnostic aspects of two- and three-dimensional ultrasound and MRI. MATERIALS AND METHODS: 63 women referred for suspected uterine anomalies were studied: In the first group (until July 2008) with 2 D-US and MRI, in the second group (from August 2008) additionally with 3 D-US; these women also had diagnostic or therapeutic operative confirmation. In the third group, only 3D-US was used. RESULTS: In all women 3D-US was possible and successful. The most common anomaly was a subseptate uterus, while a septate uterus was less frequent, and uterus bicornis (unicollis) and uterus didelphys (bicornis bicollis) were rare. The women in the first two groups all underwent at least diagnostic hysteroscopy, and some (subseptate or septate uterus) underwent operative hysteroscopy. After preoperative volume imaging, laparoscopies were required less often. 3D-US diagnoses as judged by intraoperative findings were correct in 100 % of cases, while the MRI diagnoses in the same group were correct in only 7/13 cases. CONCLUSION: Since the introduction of volume imaging (MRI, later 3 D-US), laparoscopy during hysteroscopic septum resection was not necessary in the majority of cases. 3D-US brings the diagnostics of uterine anomalies back into the hands of the gynecologist and can provide the gynecological surgeon with a higher subjective degree of certainty during operative hysteroscopy.

Pain Levels of Women Diagnosed with Endometriosis: Is There a Difference in Younger Women?

STUDY OBJECTIVE: Early diagnosis and treatment of endometriosis affecting adolescent women are important in preventing chronic pain. Our aim was to analyze the clinical characteristics and severity of symptoms in adolescent patients with endometriosis compared with older patients. METHODS: This single-center retrospective cohort study in a tertiary referral hospital analyzed women whose first consultation at the certified endometriosis center of Bern University Hospital between January 2017 and December 2020 resulted in the clinical diagnosis of endometriosis. Patients, divided into 2 groups by age, reported visual analog scale (VAS) scores for noncyclic pelvic pain, dysmenorrhea, dyschezia, dysuria, and dyspareunia. The symptom types and severity in the 2 groups were compared. The young patients with endometriosis were analyzed in greater detail, comparing VAS scores and types of endometriosis. RESULTS: From a total of 826 patients, 144 (17.4%) patients 24 years old or younger and 682 (82.6%) patients over 24 years old were compared. The younger patients reported significantly higher pain scores for dysmenorrhea (VAS 7.3 vs 6.6; P = .015), dyspareunia (VAS 4.6 vs 3.4; P = .001), and noncyclic pelvic pain (VAS 4.3 vs 3.7; P = .032) compared with the older patient collective. Similar results were found when excluding patients with hormonal treatment. CONCLUSION: Young patients with clinically diagnosed endometriosis have significantly higher dysmenorrhea and dyspareunia pain levels than older patients. By acknowledging and understanding this, early diagnosis and adequate treatment can be promoted. Dyspareunia in adolescents in particular merits clinical attention.

The unspoken disease: symptom experience in women with vulval neoplasia and surgical treatment: a qualitative study.

Women with vulval neoplasia often experience severe post-surgical complications. This study focuses on symptom experience of women during the first 6 months following surgical treatment for vulval neoplasia considering their socio-cultural context. In this qualitative study using a critical hermeneutic approach, narrative interviews were conducted. A purposeful sample of 20 patients was recruited from one Swiss and two German university hospitals. Content analysis was employed to analyse the transcribed interviews considering women's experiences and social perceptions. Narratives showed eight interrelated themes: delayed diagnosis, disclosed disease, disturbed self-image, changed vulva care, experienced wound-related symptoms, evoked emotions, affected interpersonal interactions and feared illness progression. The women experienced a general lack of information pertaining to above themes and all described strategies used to handle their situation, which affected their distress. The communication, assessment and treatment of symptoms were hampered by the society's and the health system's tendency to overlook these symptoms and leave them in the realm of the unspeakable. Health professionals need new strategies to support these women to recognise, assess and evaluate the seriousness of symptoms, and to communicate their symptom experience so that timely medical treatment is sought. This support may minimise potentially preventable complications and symptom-related distress.

Effects of female genital mutilation on birth outcomes in Switzerland.

OBJECTIVE: The primary aim of this study was to determine the desires and wishes of pregnant patients vis-à-vis their external genital anatomy after female genital mutilation (FGM) in the context of antenatal care and delivery in a teaching hospital setting in Switzerland. Our secondary aim was to determine whether women with FGM and non-mutilated women have different fetal and maternal outcomes. DESIGN: A retrospective case-control study. SETTING: A teaching hospital. POPULATION: One hundred and twenty-two patients after FGM who gave consent to participate in this study and who delivered in the Department of Obstetrics and Gynaecology in the University Hospital of Berne and 110 controls. METHODS: Data for patients' wishes concerning their FGM management, their satisfaction with the postpartum outcome and intrapartum and postpartum maternal and fetal data. As a control group, we used a group of pregnant women without FGM who delivered at the same time and who were matched for maternal age. MAIN OUTCOME MEASURES: Patients' satisfaction after delivery and defibulation after FGM, maternal and fetal delivery data and postpartum outcome measures. RESULTS: Six percent of patients wished to have their FGM defibulated antenatally, 43% requested a defibulation during labour, 34% desired a defibulation during labour only if considered necessary by the medical staff and 17% were unable to express their expectations. There were no differences for FGM patients and controls regarding fetal outcome, maternal blood loss or duration of delivery. FGM patients had significantly more often an emergency Caesarean section and third-degree vaginal tears, and significantly less first-degree and second-degree tears. CONCLUSION: An interdisciplinary approach may support optimal antenatal and intrapartum management and also the prevention of FGM in newborn daughters.

The role of 3D fusion imaging in sentinel lymphadenectomy for vulvar cancer.

OBJECTIVES: To evaluate the feasibility of fusion imaging compound tomography (FICT) of CT/MRI and single photon emission tomography (SPECT) versus planar scintigraphy only (plSc) in pre-surgical staging for vulvar cancer. MATERIALS AND METHODS: Analysis of consecutive patients with vulvar cancer who preoperatively underwent sentinel scintigraphy (planar and 3D-SPECT imaging) and CT or MRI. Body markers were used for exact anatomical co-registration and fusion datasets were reconstructed using SPECT and CT/MRI. The number and localisation of all intraoperatively identified and resected sentinel lymph nodes (SLN) were compared between planar and 3D fusion imaging. RESULTS: Twenty six SLN were localized on planar scintigraphy. Twelve additional SLN were identified after SPECT and CT/MRI reconstruction, all of them were confirmed intraoperatively. In seven cases where single foci were identified at plSc, fusion imaging revealed grouped individual nodes and five additional localisations were discovered at fusion imaging. In seven patients both methods identified SLN contra lateral to the primary tumor site, but only fusion imaging allowed to localise iliac SLN in four patients. All SLN predicted on fusion imaging could be localised and resected during surgery. CONCLUSIONS: Fusion imaging using SPECT and CT/MRI can detect SLN in vulvar cancer more precisely than planar imaging regarding number and anatomical localisation. FICT revealed additional information in seven out of ten cases (70%).

C-reactive protein production in term human placental tissue.

OBJECTIVE: C-reactive protein (CRP) is a marker of systemic inflammation. Recently, it has been shown that CRP is present in amniotic fluid and fetal urine, and that elevated levels are associated with adverse pregnancy outcome. However, the precise source of amniotic fluid CRP, its regulation, and function during pregnancy is still a matter of debate. The present in vivo and in vitro studies were designed to investigate the production of CRP in human placental tissues. MATERIAL AND METHODS: Ten paired blood samples from peripheral maternal vein (MV), umbilical cord artery (UA) and umbilical vein (UV) were collected from women with elective caesarean sections at term. The placental protein accumulation capacity of hCG, hPL, leptin and CRP was compared with the dual in vitro perfusion method of an isolated cotyledon of human term placentae and quantified by ELISA. Values for accumulation (release) were calculated as total accumulation of maternal and fetal circuits normalized for tissue weight and duration of perfusion. For gene expression, RNA was extracted from placental tissue and reverse transcribed. RT-PCR and real-time PCR were performed using specific primers. RESULTS: The median (range) CRP level was significantly different between UA and UV [50.1 ng/ml (12.1-684.6) vs. 61 ng/ml (16.9-708.1)]. The median (range) difference between UV and UA was 9.3 ng/ml (2.2-31.6). A significant correlation was found between MV CRP and both UA and UV CRP levels. Median (range) MV CRP levels [2649 ng/ml (260.1-8299)] were 61.2 (6.5-96.8) fold higher than in the fetus. In vitro, the total accumulation rates (mean+/-SD) were 31+/-13 (mU/g/min, hCG), 1.16+/-0.19 (microg/g/min, hPL), 4.71+/-1.91 (ng/g/min, CRP), and 259+/-118 (pg/g/min, leptin). mRNA for hCG, hPL and leptin was detectable using conventional RT-PCR, while CRP mRNA could only be demonstrated by applying real-time RT-PCR. In the perfused tissue the transcript levels for the four proteins were comparable to those detected in the native control tissue. CONCLUSIONS: Our results demonstrate that the human placenta produces and releases CRP mainly into the maternal circulation similarly to other analyzed placental proteins under in vitro conditions. Further studies are needed to explore the exact role of placental CRP during pregnancy.

Cigarette smoking among U.S. adults by state and region: estimates from the current population survey.

BACKGROUND: Cigarette smoking is responsible for at least one third of all cancer deaths annually in the United States. Few sources exist in the peer-reviewed literature documenting state and regional differences in smoking behavior, despite the fact that cancer prevention and control efforts are increasingly being implemented below the national level. PURPOSE: Our goals were to determine smoking prevalence rates among men and women, by region, and for each of the 50 states and the District of Columbia from census survey data collected in 1992 and 1993 and to compare these rates with rates determined in 1985. METHODS: Every month, the U.S. Bureau of the Census collects labor force statistics on more than 100000 individuals on its Current Population Survey (CPS). For the September 1992, January 1993, and May 1993 CPS, the National Cancer Institute sponsored a 40-item Tobacco Use Supplement. The definition of a current smoker changed slightly between 1985 and 1992-1993. For the 1985 CPS, individuals were considered current smokers if they had smoked 100 cigarettes in their lifetime and were smoking at the time of interview; for the 1992-1993 CPS, current smokers included anyone who had smoked 100 cigarettes and was currently smoking every day or just on some days. We calculated current smoking rates (every day and some days combined) based on more than a quarter million adults (n = 266988) interviewed in 1992-1993. RESULTS: Substantial geographic variation exists in rates of current cigarette use among adults within the United States. In general, adults in the southern United States have higher rates of smoking and adults in the western states have lower rates of smoking and adults in the rest of the country, although differences in smoking behavior between men and women and among various racial and ethnic populations strongly influence these patterns. Only two states, Kentucky and West Virginia, exhibited adult smoking rates (men and women combined) of 30% or higher in 1992-1993; in contrast, in 1985, such rates were reported from 20 states. The only states in which the prevalence was below 20% in 1992-1993 were Utah (17.1%) and California (19.5%). Rates approaching 20% were reported from New Jersey (20.7%), Massachusetts (21.5%), and Nebraska, New York, and Hawaii (22.0% each) in 1992-1993. Rhode Island experienced the greatest relative decline in smoking prevalence from 1985 to 1992-1993, with a calculated relative change of -30.7% (based on a change in rate from 33.5% to 23.2%), followed by Delaware (-25.9%) the District of Columbia and New Jersey (-23.9% each), Connecticut (-23.2%), California (-22.9%), Alaska (-22.8%), Georgia (-22.6%), Massachusetts (-22.1%), and New York (-22.0%). CONCLUSIONS: Smoking rates are not uniform in the United States but vary considerably from state to state, even within the same region of the country. The CPS is the only mechanism currently capable of simultaneously monitoring smoking trends nationally, regionally, and on a state-by-state basis.

[Practice guidelines: conservative treatment of fibroids]. / Traitement conservateur des fibromes: recommandations pour la pratique.

The conservative treatment of uterine fibroids is essentially based on symptomatology and patient's choice of treatment. The gynaecologist must develop a clear therapeutic protocol based on clinical examination, available test results and consideration of patient preference. The therapeutic options include close surveillance, hormonal treatments, conservative operative endoscopy and arterial embolization.

Laparoscopic Cerclage as a Treatment Option for Cervical Insufficiency.

Background: The traditional surgical treatment for cervical insufficiency is vaginal placement of a cervical cerclage. However, in a small number of cases a vaginal approach is not possible. A transabdominal approach can become an option for these patients. Laparoscopic cervical cerclage is associated with good pregnancy outcomes but comes at the cost of a higher risk of serious surgical complications. The aim of the present study was to evaluate intraoperative and long-term pregnancy outcomes after laparoscopic cervical cerclage, performed either as an interval procedure or during early pregnancy, using a new device with a blunt grasper and a flexible tip. Methods: All women who underwent laparoscopic cervical cerclage for cervical insufficiency in our institution using the Goldfinger® device (Ethicon Endo Surgery, Somerville, NJ, USA) between January 2008 and March 2014 were included in the study. Data were collected from the patients' medical records and included complications during and after the above-described procedure. Results: Eighteen women were included in the study. Of these, six were pregnant at the time of laparoscopic cervical cerclage. Mean duration of surgery was 55 ± 10 minutes. No serious intraoperative or postoperative complications occurred. All patients were discharged at 2.6 ± 0.9 days after surgery. One pregnancy ended in a miscarriage at 12 weeks of gestation. All other pregnancies ended at term (> 37 weeks of gestation) with good perinatal and maternal outcomes. Summary: Performing a laparoscopic cervical cerclage using a blunt grasper device with a flexible tip does not increase intraoperative complications, particularly in early pregnancy. We believe that use of this device, which is characterized by increased maneuverability, could be an important option to avoid intraoperative complications if surgical access is limited due to the anatomical situation. However, because of the small sample size, further studies are needed to confirm our findings.

Endocrine and paracrine regulation of endometrial angiogenesis.

The human endometrium is a complex tissue comprised of different cell types, including epithelial, stromal, inflammatory, perivascular, and blood vessel cells. The hormonal receptivity and distribution of these cell populations change during the menstrual cycle. Cyclical endometrial growth is dependent on its ability to regenerate a vascular capillary network, which grows in parallel with the proliferation and differentiation of the endometrial lining. Natural hormonal effects on the endometrium and endocrine manipulation of this tissue, in response to the use of exogenous steroid therapies, can affect endometrial capillary proliferation and function, leading to clinical abnormalities of uterine bleeding. We propose that the regulation of endometrial angiogenesis is mediated indirectly via complex interactions among cell types. Our laboratory has focused on a prototypical member of the angiogenic proteins, vascular endothelial growth factor (VEGF)-A. In this paper we present data demonstrating that VEGF-A expression in normal endometrial epithelial and stromal cells and in Ishikawa adenocarcinoma cells is increased by an ovarian steroid, estradiol. Infiltrating immune cells, particularly polymorphonuclear granulocytes, also are sources of VEGF-A. In inflammatory conditions involving the endometrium (e.g., endometriosis), a proinflammatory cytokine, IL-1beta, can mediate neoangiogenesis by inducing VEGF-A gene transcription. Thus, endometrial vascularization is effected by both endocrine and paracrine pathways.

Higher rate of fetal acidemia after regional anesthesia for elective cesarean delivery.

OBJECTIVE: To determine the prevalence of fetal acidemia associated with regional anesthesia for elective cesarean delivery in healthy paturients with uncomplicated singleton term pregnancies. METHODS: This was an epidemiologic study using the data base of the Swiss obstetric study group (Arbeitsgemeinschaft Schweizerischer Frauenkliniken). After the exclusion of cases with extraneous factors that may have affected the health of the neonate, we analyzed the umbilical artery pH, Apgar score, and other neonatal outcome measures after cesarean delivery with reference to the anesthetic technique. RESULTS: From 1985 to 1994, 327,763 deliveries, including 40,858 (12.47%) by cesarean, were registered in the data base. Of these, 5806 patients fulfilled the study criteria. The study population included 1002 spinal, 2155 epidural, and 2649 cases of general anesthesia. The frequency of fetal acidemia (pH less than 7.10) was significantly increased in the spinal-anesthesia group (odds ratio [OR] 4.67; 95% confidence interval [CI] 2.73, 8.01) and in the epidural group (OR 2.39; 95% CI 1.42, 4.04) compared with the general-anesthesia group. CONCLUSION: The rate of fetal acidemia is significantly increased after regional anesthesia. This risk must be judged in light of the risks inherent with general anesthesia.

Glycodelin: a pane in the implantation window.

Glycodelin is an endometrial protein with proposed immunomodulatory activity during human embryonic nidation. In this review we describe the effects of ovarian hormones on glycodelin transcription, synthesis, and secretion by human epithelial cells and focus on the importance of glycodelin in implantation. We demonstrate that glycodelin transcription, synthesis, and secretion by human epithelial cells are stimulated by progestins and antiprogestins but not by estrogen. Sequences localized within a 403-base-pair region flanking the 5' human glycodelin gene promoter appear to be responsible for transcriptional activation of this gene mediated by progesterone receptor-ligand complexes. Relaxin, purported to enhance glycodelin production in vivo and in prior in vitro studies, had no stimulatory effect on the expression of this gene in vitro in our models.

Immunobiology of endometriosis.

OBJECTIVE: To provide a review of the humoral and cellular immunology of endometriosis and to discuss the rationale for future approaches to diagnosis and treatment. DESIGN: Literature survey. RESULT(S): Defective immunosurveillance in women who are destined to develop endometriosis may allow for the survival of ectopic endometrial tissue. The evidence includes endometrial cell resistance to apoptosis, perhaps through the secretion of proteins that interfere with implant recognition and/or FasL expression by stromal cells, inducing apoptosis of Fas-bearing immune cells. Although the immune response may be defective, aspects of it clearly are enhanced in endometriosis, as is seen by the generalized polyclonal B-cell autoimmune activation and secretion of immune proteins. Several cytokines, chemokines, and growth factors (including vascular growth factors) are increased in women with endometriosis. CONCLUSION(S): A complex network of locally produced cytokines modulate the growth and inflammatory behavior of ectopic endometrial implants. Proinflammatory proteins from endometriotic lesions and associated immune cells contribute to the enhanced inflammatory reaction associated with endometriosis that subserves the survival of these lesions instead of leading to their demise.

Neutrophils infiltrating the endometrium express vascular endothelial growth factor: potential role in endometrial angiogenesis.

OBJECTIVE(S): To identify leukocytes within the human endometrium expressing vascular endothelial growth factor (VEGF). DESIGN(S): Prospective cohort study. SETTING(S): Healthy volunteers in an academic research environment. PATIENTS(S): Twenty-one normal cycling women without abnormal menstrual bleeding or infertility. INTERVENTION(S): Endometrial tissue collection by Pipelle de Cornier aspiration. MAIN OUTCOME MEASURES(S): Histologic, immunohistochemical (CD3, CD34, CD56, CD68, neutrophil elastase, estrogen and P receptors, VEGF), and simultaneous double immunoenzymatic labeling analysis of VEGF-positive cells within the human endometrium. RESULT(S): Ten endometrial samples were obtained in the proliferative (cycle days 5-10) and 11 samples in the secretory phase (cycle days 15-26). Immunohistochemical analyses showed the expected distribution of the different leukocyte cell types. Besides epithelial and stromal endometrial cells, the predominant cells that stained for VEGF were neutrophil granulocytes. Neutrophils were more abundant in the secretory phase but they expressed neither estrogen-a nor P receptors. CONCLUSION(S): Neutrophil granulocytes infiltrating the human endometrium express VEGF and regulate cyclical endometrial vascular proliferation. Ovarian steroids indirectly influence neutrophil migration.

Umbilical endometriosis.

We report two women who presented with a recurrent, mildly painful, bluish nodule in the umbilicus. Both patients complained of local tenderness and occasional bleeding that increased during menstruation. Neither patient had had previous pelvic surgery. Excision of the lesions revealed a primary umbilical endometriosis; in one case, a simultaneous laparoscopy showed a pelvic endometriosis. We review the current literature and discuss the possible etiopathogenesis and when a laparoscopy is indicated to diagnose a concomitant pelvic endometriosis. Umbilical endometriosis is a very rare disease but should be considered in the differential diagnosis of umbilical lesions.

Two-trocar adnexal surgery: a "quasi" scarless operation.

BACKGROUND: This study aimed to explore the feasibility and safety of two-port abdominal cavity entry for adnexal surgery. METHODS: A series of patients undergoing laparoscopy for benign adnexal diseases requiring adnexectomy, ovariectomy, or salpingectomy were enrolled in the study. A 10-mm 0 degree umbilical operative laparoscope and one 3- or 5-mm suprapubic trocar were used. A grasping forceps was inserted through the ancillary trocar to displace medially and cranially the adnexa or the salpinx. The operation then was performed through the operative channel of the operative laparoscope. RESULTS: A total of 53 patients were enrolled. Bilateral salpingo-oophorectomy was performed in 10 cases. The median operative time was 39 min (range, 21-85 min). The median blood loss was 50 ml (range, 0-300 ml). The median size of the adnexal mass was 6 cm (range, 3-12 cm). No intraoperative complication occurred. At the 3-month follow-up visit, no extraumbilical abdominal scar was visible. CONCLUSIONS: The use of a two-trocar technique is safe and highly appreciated by the patients it leaves no visible abdominal scars.
