Ovarian endometrioma: a report of a pediatric case diagnosed prior to menstruation. Surg Case Rep 2024; 10:152. [PMID: 38898208 PMCID: PMC11187045 DOI: 10.1186/s40792-024-01951-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2024] [Accepted: 06/12/2024] [Indexed: 06/21/2024] Open
Abstract
BACKGROUND Ovarian endometriomas (OEs) are rarely found in the pediatric population, especially before menstruation. We report a 6-year-old girl who was postoperatively diagnosed with OE before menstruation. CASE PRESENTATION A 6-year-old girl presented to a local pediatrician with abdominal pain and vomiting. Abdominal ultrasonography revealed a multilocular cystic lesion to the left of the bladder. Magnetic resonance imaging (MRI) revealed similar findings, with the contents of the cyst showing a low signal on T1-weighted imaging and a high signal on T2-weighted imaging. The patient was referred to our institution for further examination. Enhanced computed tomography (CT) showed a multilocular cystic lesion sized 56 × 44 × 30 mm with partial calcification. The left ovarian vein was dilated, suggesting the origin of the tumor to be the left ovary. Extirpation of the lesion was performed under laparoscopic assistance. Pathological findings indicated an ovarian endometrioma. To our knowledge, this is the youngest report of an OE diagnosed in a patient prior to menstruation. CONCLUSIONS OEs in children before menstruation are extremely rare; thus, the long-term prognosis is yet to be determined.

Abstract
BACKGROUND There has been considerable progress in our understanding of endometriosis, but its pathophysiology remains uncertain. Uncovering the underlying mechanism of the rare instances of endometriosis reported in early postmenarcheal years and in girls before menarche can have wide implications. METHODS We conducted a literature review of all relevant articles on Medline. RESULTS In the review, we explore the pathogenetic theories of premenarcheal endometriosis, the role of retrograde menstruation in the adult and its potential role in early-onset disease, as well as the factors that argue against the existence of a link between early-onset endometriosis (EOE) and neonatal uterine bleeding (NUB). CONCLUSIONS As with endometriosis in adult women, the pathogenesis of early-onset disease remains unclear. A link between NUB and EOE is plausible, but there are considerable challenges to collating supporting evidence. The state of our understanding of early uterine development and of the pathophysiology of NUB leaves many unknowns that need exploration. These include proof of the existence of viable endometrial cells or endometrial mesenchymal stem cells in NUB, their passage to the pelvic cavity, their possible response to steroids, and whether they can reside within the pelvic cavity and remain dormant till menarche.

Cancers (Basel) 2024; 16:809.

Abstract
This study examined the impact of hormone replacement therapy (HRT) on the occurrence of various cancers in postmenopausal women with de novo or a history of endometriosis. In the datasets for ten cancers (cervical, uterine, ovarian, breast, colon, gastric, liver, lung, pancreatic, and thyroid), women who received HRT (the HRT group) and those who did not (the control group) were selected by a 1:1 matching with those who met the study criteria. In the dataset for each cancer, the incidence of each cancer was very low (0.2% to 1.5% in the HRT group and 0.2% to 1.3% in the control group). The duration of HRT was 1.3 ± 2.1 years. After adjusting for co-variables, HRT was a significant risk factor for uterine cancer (p < 0.05). However, the risk of liver cancer decreased significantly with duration of HRT (p < 0.05). Moreover, combined estrogen and progesterone decreased the risks of liver and thyroid cancers significantly (p < 0.05), and estrogen alone decreased the risks of breast and lung cancers significantly (p < 0.05). Tibolone was not associated with the risk of any of the cancers assessed. These results can help guide the use of HRT in women with de novo or a history of endometriosis.

Neonatal uterine bleeding: Risk factors and its association with endometriosis-related symptoms later in life. Eur J Obstet Gynecol Reprod Biol 2024; 293:146-155.

Abstract
OBJECTIVE We examined the prevalence and risk factors in association with neonatal uterine bleeding (NUB) by retrospective search of contemporary and historical medical records and investigated the possible association between the history of NUB at birth and endometriosis-related symptoms later in life who are now young women. STUDY DESIGN This was a retrospective case-controlled cohort study and prospective evaluation of web-based questionnaire survey on symptoms related to endometriosis among young women born with and without NUB. Multiple regression analysis was performed incorporating various confounding variables that may influence the occurrence of NUB or the reporting of endometriosis symptoms later in life. RESULTS Among the 1093 female neonates born between 1996 and 2000, 105 of them had NUB, yielding with a prevalence of 9.6 %. Of the 807 female babies born between 2013 and 2017, 25 (3.1 %) had NUB. Multiple Logistic regression analysis indicated that younger age of the mother [odds ratio (OR) = 0.92, 95 % confidence interval (CI) = 0.85-1.00, P = 0.048] and longer gestational age of 39 weeks (OR = 3.04, 95 % CI = 1.43-6.45, P = 0.004) and of ≥ 40 weeks (OR = 4.54, 95 % CI = 2.20-9.39, P < 0.0001) of gestation were significantly associated with the occurrence of NUB. While the possibility of recall bias cannot be ruled out, newborn females who had a history of NUB appeared to complain of various endometriosis-related symptoms later in life during adulthood. CONCLUSIONS We confirmed the validity of the reported prevalence and risk factors of NUB. NUB indeed occurs with a prevalence of 3-10% during the historical and contemporary period. Longer gestational age and younger maternal age may be considered as high-risk factors for the occurrence of NUB. The clinical relevance of our findings remains to be elucidated. Future prospective studies, preferably with larger sample sizes and the inclusion of NUB cases after discharge from the hospital, may further illuminate some unresolved issues. We also need to confirm the endometriosis-related symptoms in women with and without history of NUB via more definitive diagnosis such as imaging and histology.

Abstract
The evaluation of endometriosis in an adolescent girl is a challenging topic. The initial stage of the disease and the limited diagnostic instrument appropriate for the youth age and for its typical features can reduce the ability of the gynecologist. At the same time, missing a prompt diagnosis can delay the beginning of specific and punctual management of endometriosis, which could avoid a postponed diagnosis from 6 to 12 years, typical of adolescent girls complaining of dysmenorrhea. This article aimed to answer all the potential questions around the diagnosis and management of endometriosis in adolescents starting from a clinical case looking at the possible solution that is easily reproducible in the clinical practice.

Abstract
Endometriosis is a chronic inflammatory disease associated with bothersome symptoms in premenopausal women and is complicated with long-term systemic impacts in the post-menopausal stage. It is generally defined by the presence of endometrial-like tissue outside the uterine cavity, which causes menstrual disorders, chronic pelvic pain, and infertility. Endometriotic lesions can also spread and grow in extra-pelvic sites; the chronic inflammatory status can cause systemic effects, including metabolic disorder, immune dysregulation, and cardiovascular diseases. The uncertain etiologies of endometriosis and their diverse presentations limit the treatment efficacy. High recurrence risk and intolerable side effects result in poor compliance. Current studies for endometriosis have paid attention to the advances in hormonal, neurological, and immunological approaches to the pathophysiology and their potential pharmacological intervention. Here we provide an overview of the lifelong impacts of endometriosis and summarize the updated consensus on therapeutic strategies.

Abstract
Despite the clinically recognized association between endometriosis and infertility, the mechanisms implicated in endometriosis-associated infertility are not fully understood. Endometriosis is a multifactorial and systemic disease that has pleiotropic direct and indirect effects on reproduction. A complex interaction between endometriosis subtype, pain, inflammation, altered pelvic anatomy, adhesions, disrupted ovarian reserve/function, and compromised endometrial receptivity as well as systemic effects of the disease define endometriosis-associated infertility. The population of infertile women with endometriosis is heterogeneous, and diverse patients' phenotypes can be observed in the clinical setting, thus making difficult to establish a precise diagnosis and a single mechanism of endometriosis related infertility. Moreover, clinical management of infertility associated with endometriosis can be challenging due to this heterogeneity. Innovative non-invasive diagnostic tools are on the horizon that may allow us to target the specific dysfunctional alteration in the reproduction process. Currently the treatment should be individualized according to the clinical situation and to the suspected level of impairment. Here we review the etiology of endometriosis related infertility as well as current treatment options, including the roles of surgery and assisted reproductive technologies.

Abstract
Endometriosis in adolescence represents a specific variant of the disease with its own characteristics and, in some cases, even a possibly different pathogenesis. It has its own clinical presentation, diagnostic and therapeutic modalities. The condition is not rare as once thought and certainly deserves attention in view of increasing evidence of its likely progressive nature. Numerous theories for Its pathogenesis have been formulated and they have been divided into two main categories: the 'in-situ' and the 'transplantation' hypotheses. Clinical manifestations include as the prevailing symptom a persistent chronic pelvic pain, despite medical treatment, manifested under various forms: dysmenorrhea, acyclic chronic pain, acute abdominal pain and migraines. These symptoms can substantially affect the quality of life on an adolescent. At histopathology, adolescent endometriosis is characterized by a high proportion of subtle, clear, red or vesicular implants and by the rarity of deep nodules. Frequently, the picture includes ovarian endometriomas. In some adolescent girls, lesions may regress or even disappear, probably through immune suppression; in others, chronic stress, unhealthy diet or lifestyle such as high-fat diet, may accelerate lesional progression and cause symptoms. Classically, management of adolescent endometriosis has been centered on attempts to treat dysmenorrhea; today both medical and surgical modalities have the potential to improve quality of life, alleviate symptoms, prevent the development of more severe disease and minimize risks for future fertility in adolescents. Nonetheless, at present, medical treatments are considered the first line of interventions in treating young women.

Abstract
CONTEXT Whether endometriosis is a progressive disease is a highly contentious issue. While progression is reported to be unlikely in asymptomatic deep endometriosis, progression in symptomatic deep endometriosis has recently been reported, especially in menstruating women. However, pathophysiological reasons for these differences are unclear. OBJECTIVE This study was designed to investigate whether ovarian endometrioma (OE) is progressive or not. SETTING, DESIGN, PATIENTS, INTERVENTION AND MAIN OUTCOME MEASURES Thirty adolescent patients, aged 15 to 19 years, and 32 adult patients, aged 35 to 39 years, all laparoscopically and histologically diagnosed with OE, were recruited into this study after informed consent. Their demographic and clinical information were collected. Their OE tissue samples were collected and subjected to immunohistochemical analysis for E-cadherin, α-smooth muscle actin (α-SMA), desmin, and adrenergic receptor β2 (ADRB2), as well as quantification of lesional fibrosis by Masson trichrome staining. RESULTS OE lesions from the adolescent and adult patients are markedly different, with the latter exhibiting more extensive and thorough progression and more extensive fibrosis, suggesting that lesions in adults progressed to a more advanced stage. Adult lesions and higher staining level of α-SMA and ADRB2 are positively associated with the extent of lesional fibrosis, while the lesion size and the E-cadherin staining are negatively associated. CONCLUSIONS Our data provide a more definitive piece of evidence suggesting that OE is a progressive disease, since the adult lesions have had a longer time to progress. In addition, the pace of progression depends on lesional age as well as the severity of endometriosis-associated dysmenorrhea, if any.

Abstract
Ultrasound is the first-line imaging modality in the assessment of the female reproductive system in all age groups. However, the paediatric and adolescent subset of patients present a particular set of challenges. These include technical challenges that come from largely being limited by transabdominal imaging as well as dealing with the often-complex social issues around the sexual health of adolescents. In addition, this group of patients has a unique set of pathologies that are not seen in the adult population and conversely, common gynaecological conditions affecting adults such as endometriosis and polycystic ovarian syndrome are difficult to diagnose in adolescents. Therefore, we propose that paediatric and adolescent gynaecological ultrasound requires a different approach. This paper summarises the differences in technique, common pathologies and touches on some of the relevant social issues that are unique to this population of patients.

Abstract
The etiopathogenesis of endometriosis is a multifactorial process resulting in a heterogeneous disease. Considering that endometriosis etiology and pathogenesis are still far from being fully elucidated, the current review aims to offer a comprehensive summary of the available evidence. We performed a narrative review synthesizing the findings of the English literature retrieved from computerized databases from inception to June 2019, using the Medical Subject Headings (MeSH) unique ID term "Endometriosis" (ID:D004715) with "Etiology" (ID:Q000209), "Immunology" (ID:Q000276), "Genetics" (ID:D005823) and "Epigenesis, Genetic" (ID:D044127). Endometriosis may origin from Müllerian or non-Müllerian stem cells including those from the endometrial basal layer, Müllerian remnants, bone marrow, or the peritoneum. The innate ability of endometrial stem cells to regenerate cyclically seems to play a key role, as well as the dysregulated hormonal pathways. The presence of such cells in the peritoneal cavity and what leads to the development of endometriosis is a complex process with a large number of interconnected factors, potentially both inherited and acquired. Genetic predisposition is complex and related to the combined action of several genes with limited influence. The epigenetic mechanisms control many of the processes involved in the immunologic, immunohistochemical, histological, and biological aberrations that characterize the eutopic and ectopic endometrium in affected patients. However, what triggers such alterations is not clear and may be both genetically and epigenetically inherited, or it may be acquired by the particular combination of several elements such as the persistent peritoneal menstrual reflux as well as exogenous factors. The heterogeneity of endometriosis and the different contexts in which it develops suggest that a single etiopathogenetic model is not sufficient to explain its complex pathobiology.

Abstract
Although documented rates of endometriosis in adolescent patients undergoing laparoscopy for chronic pelvic pain range from about 25% to 45%, adolescent endometriosis has received limited attention in terms of research activity and follow-up studies. In this manuscript, distinctive characteristics of adolescent and young endometriosis have been considered in order to define pathogenetic and scientific concepts that might be useful in clarifying some aspects of the adult disease as well. Some highlights relative to the cellular origin of the disease can be derived from reported cases before menarche, from the appearance of endometriotic lesions in teenagers (mostly stage I-II endometriosis), and from the relative infrequency of ovarian endometriotic cysts in this population. Adolescents and young patients might be also particularly useful for studying the natural course of the disease. To this end, clinical manifestations and recurrence patterns of the disease in adolescent patients need to be elucidated. Differences in clinical aspects of the disease between the adult and young populations are presented. Risk of recurrence and potential risk factors involved in the reappearance of the disease in teenagers are completely unknown. (Journal of Endometriosis 2010; 2: 19–25)

Abstract
Introduction The aim of this manuscript is to present a systematic review of characteristics and management of endometriosis in adolescents in order to gain some relevant insight into the most appropriate clinical management of the disease. Methods The literature review was done using electronic database PubMed focusing on the terms ‘adolescents’, ‘endometriosis’, ‘teenagers’, ‘pain’, ‘infertility’, ‘quality of life’, ‘medical’ and ‘surgical management’ from 1980 onward and was limited to articles in English. Articles were only included if they reported original relevant research. Results The 24 studies selected for review included 1148 adolescents with laparoscopic proven endometriosis. The diagnosis of endometriosis was histologically confirmed in 39.02% (448/1148) of cases. The results from trials have been tabulated and main results presented in a question and answer format. Conclusions The majority of adolescent girls with chronic pelvic pain not responding to conventional medical therapy have endometriosis (up to 80%). Laparoscopy with biopsy is the only way to diagnose endometriosis in the adolescent population, and depends on recognition of atypical manifestations of the disease. Surgical management (especially by an expert surgeon) has been shown to be beneficial in reducing pain, improving infertility, and preventing progression or recurrence of disease. Postoperative hormonal suppression helps reduce pain symptoms and recurrence of endometriomas, but it does not seem to prevent disease recurrence or progression of peritoneal endometriosis, and has not been shown to improve future fertility. Postoperative suppression until pregnancy is based on expert opinion only. There is a need for good quality properly randomized trials.

Abstract
Endometriosis is increasingly recognized as a challenging problem of both diagnosis and management in adolescent gynecology. Areas covered: This special report summarizes the current practices in the evaluation and management of endometriosis in adolescent patients. Expert commentary: We recommend prompt recognition and treatment of endometriosis whenever possible. Management should begin with empiric treatment with NSAIDS and hormonal therapy if complaints of pain interfering with daily activities are elicited. If a patient fails medical therapy after three to six months, surgical intervention is warranted by a clinician experienced in operating in this age range and familiar with the appearance of endometriosis in this age range.

Abstract
Background Endometriosis is a debilitating disease in women of child-bearing age. Objective To describe the pattern of presentation, stage of endometriosis and biophysical profile of patients with endometriosis. Method A retrospective study of 61 consecutive infertile patients between June 2003 and November 2014. Results The means (±SD) of age (years) and of body mass index (BMI) (kg/m2) of the patients were 34.1 (4.3) and 25.8 (5.0), respectively. A relatively high percentage (43, 70.5%) of the women were in the age range of 31-40 years; had normal BMI (27, 44.3%); were nulliparous (53, 86.9%) and were of primary infertility (40, 65.6%). The mean (±SD) age at menarche, of cycle length, of the duration of flow and of years trying to conceive were 12.9 (1.7) years, 29.1 (2.7) days, 4.7 (1.1) days and 5.2 (3.8) years, respectively. A high proportion of them (37, 60.7%) presented with severe endometriosis. The main symptoms at presentation was dysmenorrhea (47, 73.8%). Of the 32 (52.5%) with associated utero-tubal factor, 20 (62.5%) were in severe stage of endometriosis. Among women with endometriosis, those with primary infertility were over three times more likely to present with menorrhagia than those with secondary infertility (χ² = 4.70; p value = 0.03; OR = 3.33; 95% CI = 1.10, 10.12). Only 3 (4.9%) had diagnosis of endometriosis in first-degree relative. Dysmenorrhea was a strong predictor of severe endometriosis. Conclusions There may be some trends in the biophysical profile of infertile women with endometriosis which may influence diagnosis and management.

Abstract
INTRODUCTION The aim of our study was to compare the stage and severity of endometriosis in fertile and infertile women with congenital uterine malformations. MATERIAL AND METHODS We performed an observational study from September 2007 to December 2015 in a tertiary care university hospital and assisted reproductive technology center. A total of 52 patients with surgically proven uterine malformations were included. We compared 41 infertile patients with uterine malformations with 11 fertile patients with uterine malformation. The main outcome was the stage, score and type of endometriosis in regard to infertility and class of uterine malformation. RESULTS The rate of endometriosis did not differ between the two groups (43.9 vs. 36.4%). The mean revised American Fertility Society score was higher in infertile patients with uterine malformations (19.02 vs. 6, p < 0.05). No significant difference was found in the rate of superficial peritoneal endometriosis (43.9 vs. 37.5%). Endometrioma and deep infiltrating endometriosis were associated with uterine malformations in infertile women, respectively 14.6 and 0%. No difference in the characteristics of endometriosis was found regarding the class of malformation. CONCLUSIONS The association of uterine malformations and infertility may increase the severity of endometriosis and raise the issue of their diagnosis and management.

Abstract
BACKGROUND About 10% of women of reproductive age suffer from endometriosis, a costly chronic disease causing pelvic pain and subfertility. Laparoscopy is the gold standard diagnostic test for endometriosis, but is expensive and carries surgical risks. Currently, there are no non-invasive tests available in clinical practice to accurately diagnose endometriosis. This review assessed the diagnostic accuracy of combinations of different non-invasive testing modalities for endometriosis and provided a summary of all the reviews in the non-invasive tests for endometriosis series. OBJECTIVES To estimate the diagnostic accuracy of any combination of non-invasive tests for the diagnosis of pelvic endometriosis (peritoneal and/or ovarian or deep infiltrating) compared to surgical diagnosis as a reference standard. The combined tests were evaluated as replacement tests for diagnostic surgery and triage tests to assist decision-making to undertake diagnostic surgery for endometriosis. SEARCH METHODS We did not restrict the searches to particular study designs, language or publication dates. We searched CENTRAL to July 2015, MEDLINE and EMBASE to May 2015, as well as the following databases to April 2015: CINAHL, PsycINFO, Web of Science, LILACS, OAIster, TRIP, ClinicalTrials.gov, DARE and PubMed. SELECTION CRITERIA We considered published, peer-reviewed, randomised controlled or cross-sectional studies of any size, including prospectively collected samples from any population of women of reproductive age suspected of having one or more of the following target conditions: ovarian, peritoneal or deep infiltrating endometriosis (DIE). We included studies comparing the diagnostic test accuracy of a combination of several testing modalities with the findings of surgical visualisation of endometriotic lesions. DATA COLLECTION AND ANALYSIS Three review authors independently collected and performed a quality assessment of the data from each study by using the QUADAS-2 tool. For each test, the data were classified as positive or negative for the surgical detection of endometriosis and sensitivity and specificity estimates were calculated. The bivariate model was planned to obtain pooled estimates of sensitivity and specificity whenever sufficient data were available. The predetermined criteria for a clinically useful test to replace diagnostic surgery were a sensitivity of 0.94 and a specificity of 0.79 to detect endometriosis. We set the criteria for triage tests at a sensitivity of 0.95 and above and a specificity of 0.50 and above, which 'rules out' the diagnosis with high accuracy if there is a negative test result (SnOUT test), or a sensitivity of 0.50 and above and a specificity of 0.95 and above, which 'rules in' the diagnosis with high accuracy if there is a positive result (SpIN test). MAIN RESULTS Eleven eligible studies included 1339 participants. All the studies were of poor methodological quality. Seven studies evaluated pelvic endometriosis, one study considered DIE and/or ovarian endometrioma, two studies differentiated endometrioma from other ovarian cysts and one study addressed mapping DIE at specific anatomical sites. Fifteen different diagnostic combinations were assessed, including blood, urinary or endometrial biomarkers, transvaginal ultrasound (TVUS) and clinical history or examination. We did not pool estimates of sensitivity and specificity, as each study analysed independent combinations of the non-invasive tests.Tests that met the criteria for a replacement test were: a combination of serum IL-6 (cut-off >15.4 pg/ml) and endometrial PGP 9.5 for pelvic endometriosis (sensitivity 1.00 (95% confidence interval (CI) 0.91 to 1.00), specificity 0.93 (95% CI, 0.80, 0.98) and the combination of vaginal examination and transvaginal ultrasound (TVUS) for rectal endometriosis (sensitivity 0.96 (95% CI 0.86 to 0.99), specificity 0.98 (95% CI 0.94 to 1.00)). Tests that met the criteria for SpIN triage tests for pelvic endometriosis were: 1. a multiplication of urine vitamin-D-binding protein (VDBP) and serum CA-125 (cut-off >2755) (sensitivity 0.74 (95% CI 0.60 to 0.84), specificity 0.97 (95% CI 0.86 to 1.00)) and 2. a combination of history (length of menses), serum CA-125 (cut-off >35 U/ml) and endometrial leukocytes (sensitivity 0.61 (95% CI 0.54 to 0.69), specificity 0.95 (95% CI 0.91 to 0.98)). For endometrioma, the following combinations qualified as SpIN test: 1. TVUS and either serum CA-125 (cut-off ≥25 U/ml) or CA 19.9 (cut-off ≥12 U/ml) (sensitivity 0.79 (95% CI 0.64 to 0.91), specificity 0.97 (95% CI 0.91 to 1.00)); 2. TVUS and serum CA 19.9 (cut-off ≥12 U/ml) (sensitivity 0.54 (95% CI 0.37 to 0.70), specificity 0.97 (95% CI 0.91 to 1.0)); 3-4. TVUS and serum CA-125 (cut-off ≥20 U/ml or cut-off ≥25 U/ml) (sensitivity 0.69 (95% CI 0.49 to 0.85), specificity 0.96 (95% CI 0.88 to 0.99)); 5. TVUS and serum CA-125 (cut-off ≥35 U/ml) (sensitivity 0.52 (95% CI 0.33 to 0.71), specificity 0.97 (95% CI 0.90 to 1.00)). A combination of vaginal examination and TVUS reached the threshold for a SpIN test for obliterated pouch of Douglas (sensitivity 0.87 (95% CI 0.69 to 0.96), specificity 0.98 (95% CI 0.95 to 1.00)), vaginal wall endometriosis (sensitivity 0.82 (95% CI 0.60 to 0.95), specificity 0.99 (95% CI 0.97 to 1.0)) and rectovaginal septum endometriosis (sensitivity 0.88 (95% CI 0.47 to 1.00), specificity 0.99 (95% CI 0.96 to 1.00)).All the tests were evaluated in individual studies and displayed wide CIs. Due to the heterogeneity and high risk of bias of the included studies, the clinical utility of the studied combination diagnostic tests for endometriosis remains unclear. AUTHORS' CONCLUSIONS None of the biomarkers evaluated in this review could be evaluated in a meaningful way and there was insufficient or poor-quality evidence. Laparoscopy remains the gold standard for the diagnosis of endometriosis and using any non-invasive tests should only be undertaken in a research setting.

Abstract
BACKGROUND About 10% of reproductive-aged women suffer from endometriosis, a costly chronic disease causing pelvic pain and subfertility. Laparoscopy is the gold standard diagnostic test for endometriosis, but is expensive and carries surgical risks. Currently, there are no non-invasive or minimally invasive tests available in clinical practice to accurately diagnose endometriosis. Although other reviews have assessed the ability of blood tests to diagnose endometriosis, this is the first review to use Cochrane methods, providing an update on the rapidly expanding literature in this field. OBJECTIVES To evaluate blood biomarkers as replacement tests for diagnostic surgery and as triage tests to inform decisions on surgery for endometriosis. Specific objectives include:1. To provide summary estimates of the diagnostic accuracy of blood biomarkers for the diagnosis of peritoneal, ovarian and deep infiltrating pelvic endometriosis, compared to surgical diagnosis as a reference standard.2. To assess the diagnostic utility of biomarkers that could differentiate ovarian endometrioma from other ovarian masses. SEARCH METHODS We did not restrict the searches to particular study designs, language or publication dates. We searched CENTRAL to July 2015, MEDLINE and EMBASE to May 2015, as well as these databases to 20 April 2015: CINAHL, PsycINFO, Web of Science, LILACS, OAIster, TRIP, ClinicalTrials.gov, DARE and PubMed. SELECTION CRITERIA We considered published, peer-reviewed, randomised controlled or cross-sectional studies of any size, including prospectively collected samples from any population of reproductive-aged women suspected of having one or more of the following target conditions: ovarian, peritoneal or deep infiltrating endometriosis (DIE). We included studies comparing the diagnostic test accuracy of one or more blood biomarkers with the findings of surgical visualisation of endometriotic lesions. DATA COLLECTION AND ANALYSIS Two authors independently collected and performed a quality assessment of data from each study. For each diagnostic test, we classified the data as positive or negative for the surgical detection of endometriosis, and we calculated sensitivity and specificity estimates. We used the bivariate model to obtain pooled estimates of sensitivity and specificity whenever sufficient datasets were available. The predetermined criteria for a clinically useful blood test to replace diagnostic surgery were a sensitivity of 0.94 and a specificity of 0.79 to detect endometriosis. We set the criteria for triage tests at a sensitivity of ≥ 0.95 and a specificity of ≥ 0.50, which 'rules out' the diagnosis with high accuracy if there is a negative test result (SnOUT test), or a sensitivity of ≥ 0.50 and a specificity of ≥ 0.95, which 'rules in' the diagnosis with high accuracy if there is a positive result (SpIN test). MAIN RESULTS We included 141 studies that involved 15,141 participants and evaluated 122 blood biomarkers. All the studies were of poor methodological quality. Studies evaluated the blood biomarkers either in a specific phase of the menstrual cycle or irrespective of the cycle phase, and they tested for them in serum, plasma or whole blood. Included women were a selected population with a high frequency of endometriosis (10% to 85%), in which surgery was indicated for endometriosis, infertility work-up or ovarian mass. Seventy studies evaluated the diagnostic performance of 47 blood biomarkers for endometriosis (44 single-marker tests and 30 combined tests of two to six blood biomarkers). These were angiogenesis/growth factors, apoptosis markers, cell adhesion molecules, high-throughput markers, hormonal markers, immune system/inflammatory markers, oxidative stress markers, microRNAs, tumour markers and other proteins. Most of these biomarkers were assessed in small individual studies, often using different cut-off thresholds, and we could only perform meta-analyses on the data sets for anti-endometrial antibodies, interleukin-6 (IL-6), cancer antigen-19.9 (CA-19.9) and CA-125. Diagnostic estimates varied significantly between studies for each of these biomarkers, and CA-125 was the only marker with sufficient data to reliably assess sources of heterogeneity.The mean sensitivities and specificities of anti-endometrial antibodies (4 studies, 759 women) were 0.81 (95% confidence interval (CI) 0.76 to 0.87) and 0.75 (95% CI 0.46 to 1.00). For IL-6, with a cut-off value of > 1.90 to 2.00 pg/ml (3 studies, 309 women), sensitivity was 0.63 (95% CI 0.52 to 0.75) and specificity was 0.69 (95% CI 0.57 to 0.82). For CA-19.9, with a cut-off value of > 37.0 IU/ml (3 studies, 330 women), sensitivity was 0.36 (95% CI 0.26 to 0.45) and specificity was 0.87 (95% CI 0.75 to 0.99).Studies assessed CA-125 at different thresholds, demonstrating the following mean sensitivities and specificities: for cut-off > 10.0 to 14.7 U/ml: 0.70 (95% CI 0.63 to 0.77) and 0.64 (95% CI 0.47 to 0.82); for cut-off > 16.0 to 17.6 U/ml: 0.56 (95% CI 0.24, 0.88) and 0.91 (95% CI 0.75, 1.00); for cut-off > 20.0 U/ml: 0.67 (95% CI 0.50 to 0.85) and 0.69 (95% CI 0.58 to 0.80); for cut-off > 25.0 to 26.0 U/ml: 0.73 (95% CI 0.67 to 0.79) and 0.70 (95% CI 0.63 to 0.77); for cut-off > 30.0 to 33.0 U/ml: 0.62 (95% CI 0.45 to 0.79) and 0.76 (95% CI 0.53 to 1.00); and for cut-off > 35.0 to 36.0 U/ml: 0.40 (95% CI 0.32 to 0.49) and 0.91 (95% CI 0.88 to 0.94).We could not statistically evaluate other biomarkers meaningfully, including biomarkers that were assessed for their ability to differentiate endometrioma from other benign ovarian cysts.Eighty-two studies evaluated 97 biomarkers that did not differentiate women with endometriosis from disease-free controls. Of these, 22 biomarkers demonstrated conflicting results, with some studies showing differential expression and others no evidence of a difference between the endometriosis and control groups. AUTHORS' CONCLUSIONS Of the biomarkers that were subjected to meta-analysis, none consistently met the criteria for a replacement or triage diagnostic test. A subset of blood biomarkers could prove useful either for detecting pelvic endometriosis or for differentiating ovarian endometrioma from other benign ovarian masses, but there was insufficient evidence to draw meaningful conclusions. Overall, none of the biomarkers displayed enough accuracy to be used clinically outside a research setting. We also identified blood biomarkers that demonstrated no diagnostic value in endometriosis and recommend focusing research resources on evaluating other more clinically useful biomarkers.

Abstract
BACKGROUND About 10% of reproductive-aged women suffer from endometriosis, which is a costly, chronic disease that causes pelvic pain and subfertility. Laparoscopy is the gold standard diagnostic test for endometriosis, but it is expensive and carries surgical risks. Currently, there are no non-invasive tests available in clinical practice that accurately diagnose endometriosis. This is the first diagnostic test accuracy review of endometrial biomarkers for endometriosis that utilises Cochrane methodologies, providing an update on the rapidly expanding literature in this field. OBJECTIVES To determine the diagnostic accuracy of the endometrial biomarkers for pelvic endometriosis, using a surgical diagnosis as the reference standard. We evaluated the tests as replacement tests for diagnostic surgery and as triage tests to inform decisions to undertake surgery for endometriosis. SEARCH METHODS We did not restrict the searches to particular study designs, language or publication dates. To identify trials, we searched the following databases: CENTRAL (2015, July), MEDLINE (inception to May 2015), EMBASE (inception to May 2015), CINAHL (inception to April 2015), PsycINFO (inception to April 2015), Web of Science (inception to April 2015), LILACS (inception to April 2015), OAIster (inception to April 2015), TRIP (inception to April 2015) and ClinicalTrials.gov (inception to April 2015). We searched DARE and PubMed databases up to April 2015 to identify reviews and guidelines as sources of references to potentially relevant studies. We also performed searches for papers recently published and not yet indexed in the major databases. The search strategies incorporated words in the title, abstract, text words across the record and the medical subject headings (MeSH). SELECTION CRITERIA We considered published peer-reviewed, randomised controlled or cross-sectional studies of any size that included prospectively collected samples from any population of reproductive-aged women suspected of having one or more of the following target conditions: ovarian, peritoneal or deep infiltrating endometriosis (DIE). DATA COLLECTION AND ANALYSIS Two authors independently extracted data from each study and performed a quality assessment. For each endometrial diagnostic test, we classified the data as positive or negative for the surgical detection of endometriosis and calculated the estimates of sensitivity and specificity. We considered two or more tests evaluated in the same cohort as separate data sets. We used the bivariate model to obtain pooled estimates of sensitivity and specificity whenever sufficient data were available. The predetermined criteria for a clinically useful test to replace diagnostic surgery was one with a sensitivity of 94% and a specificity of 79%. The criteria for triage tests were set at sensitivity at or above 95% and specificity at or above 50%, which in case of negative results rules out the diagnosis (SnOUT test) or sensitivity at or above 50% with specificity at or above 95%, which in case of positive result rules in the diagnosis (SpIN test). MAIN RESULTS We included 54 studies involving 2729 participants, most of which were of poor methodological quality. The studies evaluated endometrial biomarkers either in specific phases of the menstrual cycle or outside of it, and the studies tested the biomarkers either in menstrual fluid, in whole endometrial tissue or in separate endometrial components. Twenty-seven studies evaluated the diagnostic performance of 22 endometrial biomarkers for endometriosis. These were angiogenesis and growth factors (PROK-1), cell-adhesion molecules (integrins α3β1, α4β1, β1 and α6), DNA-repair molecules (hTERT), endometrial and mitochondrial proteome, hormonal markers (CYP19, 17βHSD2, ER-α, ER-β), inflammatory markers (IL-1R2), myogenic markers (caldesmon, CALD-1), neural markers (PGP 9.5, VIP, CGRP, SP, NPY, NF) and tumour markers (CA-125). Most of these biomarkers were assessed in single studies, whilst only data for PGP 9.5 and CYP19 were available for meta-analysis. These two biomarkers demonstrated significant diversity for the diagnostic estimates between the studies; however, the data were too limited to reliably determine the sources of heterogeneity. The mean sensitivities and specificities of PGP 9.5 (7 studies, 361 women) were 0.96 (95% confidence interval (CI) 0.91 to 1.00) and 0.86 (95% CI 0.70 to 1.00), after excluding one outlier study, and for CYP19 (8 studies, 444 women), they were were 0.77 (95% CI 0.70 to 0.85) and 0.74 (95% CI 0.65 to 84), respectively. We could not statistically evaluate other biomarkers in a meaningful way. An additional 31 studies evaluated 77 biomarkers that showed no evidence of differences in expression levels between the groups of women with and without endometriosis. AUTHORS' CONCLUSIONS We could not statistically evaluate most of the biomarkers assessed in this review in a meaningful way. In view of the low quality of most of the included studies, the findings of this review should be interpreted with caution. Although PGP 9.5 met the criteria for a replacement test, it demonstrated considerable inter study heterogeneity in diagnostic estimates, the source of which could not be determined. Several endometrial biomarkers, such as endometrial proteome, 17βHSD2, IL-1R2, caldesmon and other neural markers (VIP, CGRP, SP, NPY and combination of VIP, PGP 9.5 and SP) showed promising evidence of diagnostic accuracy, but there was insufficient or poor quality evidence for any clinical recommendations. Laparoscopy remains the gold standard for the diagnosis of endometriosis, and using any non-invasive tests should only be undertaken in a research setting. We have also identified a number of biomarkers that demonstrated no diagnostic value for endometriosis. We recommend that researchers direct future studies towards biomarkers with high diagnostic potential in good quality diagnostic studies.

Abstract
STUDY OBJECTIVE To evaluate the prevalence of pain symptoms suggestive of endometriosis among adolescent girls aged 15-19 years. DESIGN Cross-sectional study. SETTING University hospital. PARTICIPANTS Adolescent girls aged 15-19 years attending elementary school, high school, or vocational institute at 3 cities in Southwest Finland in 2010-2011. INTERVENTIONS The school nurses distributed a detailed questionnaire to 2582 girls who were attending school at the time of the study. Completion of the questionnaire was voluntary and anonymous. MAIN OUTCOME MEASURES Prevalence and severity of dysmenorrhea, acyclic abdominal pain, dyspareunia, dyschezia, and dysuria. Severity was evaluated with an 11-point numerical rating scale (NRS). RESULTS A total of 1103 eligible answers were analyzed. The prevalence of dysmenorrhea was 68% (738/1092) with mean NRS of 7.0 (SD = 2.0). Acyclic abdominal pain, dyspareunia, dyschezia, and dysuria were less frequent (19% [207/1085], 12% [53/458], 8% [87/1088] and 5% [50/1084], respectively). The prevalence of severe dysmenorrhea (NRS 8-10) was 33% (355/1089). Severe dysmenorrhea was associated with increased risk of concurrent acyclic abdominal pain (odds ratio [OR] = 2.7; 95% confidence interval [CI], 2.0-3.6), dyschezia (OR = 2.5; 95% CI, 1.6-3.9), and regular absenteeism from school or hobbies (OR = 10.0; 95% CI, 4.2-23.6). Using different criteria, 2%-10% (21-106/1103) of all girls could be identified as having symptoms suggestive of endometriosis. Five percent of girls (n = 53/1103) had severe dysmenorrhea, used oral contraceptive pills, and reported inadequate relief from pain medication. CONCLUSION One-third (355/1089) of 15- to 19-year-old girls had severe menstrual pain and 14% (49/355) of them were regularly absent from school or hobbies. Five percent of all teenage girls (53/1103) were poor responders to conventional therapy for primary dysmenorrhea.

BACKGROUND About 10% of women of reproductive age suffer from endometriosis. Endometriosis is a costly chronic disease that causes pelvic pain and subfertility. Laparoscopy, the gold standard diagnostic test for endometriosis, is expensive and carries surgical risks. Currently, no non-invasive tests that can be used to accurately diagnose endometriosis are available in clinical practice. This is the first review of diagnostic test accuracy of imaging tests for endometriosis that uses Cochrane methods to provide an update on the rapidly expanding literature in this field. OBJECTIVES • To provide estimates of the diagnostic accuracy of imaging modalities for the diagnosis of pelvic endometriosis, ovarian endometriosis and deeply infiltrating endometriosis (DIE) versus surgical diagnosis as a reference standard.• To describe performance of imaging tests for mapping of deep endometriotic lesions in the pelvis at specific anatomical sites.Imaging tests were evaluated as replacement tests for diagnostic surgery and as triage tests that would assist decision making regarding diagnostic surgery for endometriosis. SEARCH METHODS We searched the following databases to 20 April 2015: MEDLINE, CENTRAL, EMBASE, CINAHL, PsycINFO, Web of Science, LILACS, OAIster, TRIP, ClinicalTrials.gov, MEDION, DARE, and PubMed. Searches were not restricted to a particular study design or language nor to specific publication dates. The search strategy incorporated words in the title, abstracts, text words across the record and medical subject headings (MeSH). SELECTION CRITERIA We considered published peer-reviewed cross-sectional studies and randomised controlled trials of any size that included prospectively recruited women of reproductive age suspected of having one or more of the following target conditions: endometrioma, pelvic endometriosis, DIE or endometriotic lesions at specific intrapelvic anatomical locations. We included studies that compared the diagnostic test accuracy of one or more imaging modalities versus findings of surgical visualisation of endometriotic lesions. DATA COLLECTION AND ANALYSIS Two review authors independently collected and performed a quality assessment of data from each study. For each imaging test, data were classified as positive or negative for surgical detection of endometriosis, and sensitivity and specificity estimates were calculated. If two or more tests were evaluated in the same cohort, each was considered as a separate data set. We used the bivariate model to obtain pooled estimates of sensitivity and specificity when sufficient data sets were available. Predetermined criteria for a clinically useful imaging test to replace diagnostic surgery included sensitivity ≥ 94% and specificity ≥ 79%. Criteria for triage tests were set at sensitivity ≥ 95% and specificity ≥ 50%, ruling out the diagnosis with a negative result (SnNout test - if sensitivity is high, a negative test rules out pathology) or at sensitivity ≥ 50% with specificity ≥ 95%, ruling in the diagnosis with a positive result (SpPin test - if specificity is high, a positive test rules in pathology). MAIN RESULTS We included 49 studies involving 4807 women: 13 studies evaluated pelvic endometriosis, 10 endometriomas and 15 DIE, and 33 studies addressed endometriosis at specific anatomical sites. Most studies were of poor methodological quality. The most studied modalities were transvaginal ultrasound (TVUS) and magnetic resonance imaging (MRI), with outcome measures commonly demonstrating diversity in diagnostic estimates; however, sources of heterogeneity could not be reliably determined. No imaging test met the criteria for a replacement or triage test for detecting pelvic endometriosis, albeit TVUS approached the criteria for a SpPin triage test. For endometrioma, TVUS (eight studies, 765 participants; sensitivity 0.93 (95% confidence interval (CI) 0.87, 0.99), specificity 0.96 (95% CI 0.92, 0.99)) qualified as a SpPin triage test and approached the criteria for a replacement and SnNout triage test, whereas MRI (three studies, 179 participants; sensitivity 0.95 (95% CI 0.90, 1.00), specificity 0.91 (95% CI 0.86, 0.97)) met the criteria for a replacement and SnNout triage test and approached the criteria for a SpPin test. For DIE, TVUS (nine studies, 12 data sets, 934 participants; sensitivity 0.79 (95% CI 0.69, 0.89) and specificity 0.94 (95% CI 0.88, 1.00)) approached the criteria for a SpPin triage test, and MRI (six studies, seven data sets, 266 participants; sensitivity 0.94 (95% CI 0.90, 0.97), specificity 0.77 (95% CI 0.44, 1.00)) approached the criteria for a replacement and SnNout triage test. Other imaging tests assessed in small individual studies could not be statistically evaluated.TVUS met the criteria for a SpPin triage test in mapping DIE to uterosacral ligaments, rectovaginal septum, vaginal wall, pouch of Douglas (POD) and rectosigmoid. MRI met the criteria for a SpPin triage test for POD and vaginal and rectosigmoid endometriosis. Transrectal ultrasonography (TRUS) might qualify as a SpPin triage test for rectosigmoid involvement but could not be adequately assessed for other anatomical sites because heterogeneous data were scant. Multi-detector computerised tomography enema (MDCT-e) displayed the highest diagnostic performance for rectosigmoid and other bowel endometriosis and met the criteria for both SpPin and SnNout triage tests, but studies were too few to provide meaningful results.Diagnostic accuracies were higher for TVUS with bowel preparation (TVUS-BP) and rectal water contrast (RWC-TVS) and for 3.0TMRI than for conventional methods, although the paucity of studies precluded statistical evaluation. AUTHORS' CONCLUSIONS None of the evaluated imaging modalities were able to detect overall pelvic endometriosis with enough accuracy that they would be suggested to replace surgery. Specifically for endometrioma, TVUS qualified as a SpPin triage test. MRI displayed sufficient accuracy to suggest utility as a replacement test, but the data were too scant to permit meaningful conclusions. TVUS could be used clinically to identify additional anatomical sites of DIE compared with MRI, thus facilitating preoperative planning. Rectosigmoid endometriosis was the only site that could be accurately mapped by using TVUS, TRUS, MRI or MDCT-e. Studies evaluating recent advances in imaging modalities such as TVUS-BP, RWC-TVS, 3.0TMRI and MDCT-e were observed to have high diagnostic accuracies but were too few to allow prudent evaluation of their diagnostic role. In view of the low quality of most of the included studies, the findings of this review should be interpreted with caution. Future well-designed diagnostic studies undertaken to compare imaging tests for diagnostic test accuracy and costs are recommended.

Abstract
BACKGROUND About 10% of reproductive-aged women suffer from endometriosis which is a costly chronic disease that causes pelvic pain and subfertility. Laparoscopy is the 'gold standard' diagnostic test for endometriosis, but it is expensive and carries surgical risks. Currently, there are no simple non-invasive or minimally-invasive tests available in clinical practice that accurately diagnoses endometriosis. OBJECTIVES 1. To provide summary estimates of the diagnostic accuracy of urinary biomarkers for the diagnosis of pelvic endometriosis compared to surgical diagnosis as a reference standard.2. To assess the diagnostic utility of biomarkers that could differentiate ovarian endometrioma from other ovarian masses.Urinary biomarkers were evaluated as replacement tests for surgical diagnosis and as triage tests to inform decisions to undertake surgery for endometriosis. SEARCH METHODS The searches were not restricted to particular study design, language or publication dates. We searched the following databases to 20 April - 31 July 2015: CENTRAL, MEDLINE, EMBASE, CINAHL, PsycINFO, Web of Science, LILACS, OAIster, TRIP and ClinicalTrials.gov (trial register). MEDION, DARE, and PubMed were also searched to identify reviews and guidelines as reference sources of potentially relevant studies. Recently published papers not yet indexed in the major databases were also sought. The search strategy incorporated words in the title, abstract, text words across the record and the medical subject headings (MeSH) and was modified for each database. SELECTION CRITERIA Published peer-reviewed, randomised controlled or cross-sectional studies of any size were considered, which included prospectively collected samples from any population of reproductive-aged women suspected of having one or more of the following target conditions: ovarian, peritoneal or deep infiltrating endometriosis (DIE). We included studies comparing the diagnostic test accuracy of one or more urinary biomarkers with surgical visualisation of endometriotic lesions. DATA COLLECTION AND ANALYSIS Two authors independently collected and performed a quality assessment of the data from each study. For each diagnostic test, the data were classified as positive or negative for the surgical detection of endometriosis and sensitivity and specificity estimates were calculated. If two or more tests were evaluated in the same cohort, each was considered as a separate data set. The bivariate model was used to obtain pooled estimates of sensitivity and specificity whenever sufficient data sets were available. The predetermined criteria for a clinically useful urine test to replace diagnostic surgery was one with a sensitivity of 94% and a specificity of 79% to detect endometriosis. The criteria for triage tests were set at sensitivity of equal or greater than 95% and specificity of equal or greater than 50%, which in case of negative result rules out the diagnosis (SnOUT test) or sensitivity of equal or greater than 50% with specificity of equal or greater than 95%, which in case of positive result rules the diagnosis in (SpIN test). MAIN RESULTS We included eight studies involving 646 participants, most of which were of poor methodological quality. The urinary biomarkers were evaluated either in a specific phase of menstrual cycle or irrespective of the cycle phase. Five studies evaluated the diagnostic performance of four urinary biomarkers for endometriosis, including three biomarkers distinguishing women with and without endometriosis (enolase 1 (NNE); vitamin D binding protein (VDBP); and urinary peptide profiling); and one biomarker (cytokeratin 19 (CK 19)) showing no significant difference between the two groups. All of these biomarkers were assessed in small individual studies and could not be statistically evaluated in a meaningful way. None of the biomarkers met the criteria for a replacement test or a triage test. Three studies evaluated three biomarkers that did not differentiate women with endometriosis from disease-free controls. AUTHORS' CONCLUSIONS There was insufficient evidence to recommend any urinary biomarker for use as a replacement or triage test in clinical practice for the diagnosis of endometriosis. Several urinary biomarkers may have diagnostic potential, but require further evaluation before being introduced into routine clinical practice. Laparoscopy remains the gold standard for the diagnosis of endometriosis, and diagnosis of endometriosis using urinary biomarkers should only be undertaken in a research setting.

Abstract
Adolescents present to outpatient and acute care settings commonly for evaluation and treatment of chronic pelvic pain (CPP). Primary care providers, gynecologists, pediatric and general surgeons, emergency department providers, and other specialists should be familiar with both gynecologic and nongynecologic causes of CPP so as to avoid delayed diagnoses and potential adverse sequelae. Treatment may include medications, surgery, physical therapy, trigger-point injections, psychological counseling, and complementary/alternative medicine. Additional challenges arise in caring for this patient population because of issues of confidentiality, embarrassment surrounding the history or examination, and combined parent-child decision making.

Abstract
The incidence and severity of endometriosis in adolescent are comparable with the incidence in adult women. The mean delay between the onset of symptoms and the final diagnosis varies between 6.4 and 11.7 years. The longer the diagnosis is delayed, the more the endometriosis can progress to a more severe stage certainly in the group of patients with pelvic pain. The evolution of endometriosis and its progressivity are not predictable, and the severity of the disease is not directly related to the degree of pain. Endometriotic cysts have a detrimental effect on the ovarian reserve by the evolution in time and the surgical excision technique. Already, in small endometriotic cysts (<4 cm), loss of follicular reserve is present together with the formation of fibrosis in the cortex of the ovary. Early diagnosis of endometriosis in the adolescent deserves our full attention. Non-invasive imaging techniques like 2-D and 3-D ultrasound are helpful in the early diagnosis. Early ablative surgery is recommendable. Although laparoscopy is traditionally recommended, transvaginal laparoscopy has been shown to be most effective in ablating endometriomas with a maximum diameter of 3 cm. Early detection and intervention will contribute to a better quality of life in these adolescents and also to a lower damage of the ovarian tissue by a less invasive ablative surgery.

Abstract
Endometriosis in the adolescent has, in recent years, been discovered to be a challenging problem in gynaecology. Although the pain may start at a young age, even before the onset of menstruation, the diagnosis by laparoscopy is almost always postponed for several years, by which time destructive lesions have affected the tubo-ovarian structures and severely compromised fecundability. Several factors may play a role, but one important reason for this disease progression is likely to be the delay in diagnosis. Therefore, transvaginal ultrasounds and transvaginal access with a less invasive needle endoscopy are recommended for exploration of the pelvis, diagnosis of endometriosis and treatment at an early stage before severe lesions develop.

Abstract
BACKGROUND Endometriosis associated with pain symptoms in adolescents has been extensively reported, but the exact prevalence is unclear because pain symptoms may be atypical and endometriosis can only be diagnosed by laparoscopy. The aim of this paper is to provide a systematic review of the prevalence of endometriosis diagnosed by laparoscopy in adolescents. METHODS A systematic literature search was carried out for relevant articles published between 1980 and 2011 in the databases PUBMED and EMBASE, based on the keywords 'endometriosis', 'laparoscopy', 'adolescents' and 'chronic pelvic pain (CPP)'. In addition, the reference lists of the selected articles were examined. RESULTS Based on 15 selected studies, the overall prevalence of visually confirmed endometriosis was 62% (543/880; range 25-100%) in all adolescent girls undergoing laparoscopic investigation, 75% (237/314) in girls with CPP resistant to treatment, 70% (102/146) in girls with dysmenorrhea and 49% (204/420) in girls with CPP that is not necessarily resistant to treatment. Among the adolescent girls with endometriosis, the overall prevalence of American Society of Reproductive Medicine classified moderate-severe endometriosis was 32% (82/259) in all girls, 16% (17/108) in girls with CPP resistant to treatment, 29% (21/74) in girls with dysmenorrhea and 57% (44/77) in girls with CPP that is not necessarily resistant to treatment. Due to the quality of the included papers an overestimation of the prevalence and/or severity of endometriosis is possible. CONCLUSIONS About two-thirds of adolescent girls with CPP or dysmenorrhea have laparoscopic evidence of endometriosis. About one-third of these adolescents with endometriosis have moderate-severe disease. The value of early detection of endometriosis in symptomatic adolescents and the indications for laparoscopic investigation in adolescents require more research.

Abstract
The aim of this study was to determine serum and peritoneal interleukin (IL)-2, IL-4, and monocyte chemotactic protein-1 levels as diagnostic markers of endometriosis in adolescent girls. The design of the study encompassed 50 adolescent girls, aged 13 to 19 years after menarche, with chronic pelvic pain who qualified for diagnostic laparoscopy. The patients were allocated into 2 groups: group I (endometriosis) consisted of subjects with diagnosed endometriosis (n = 33, 66%) and group II (control) whose laparoscopic examinations revealed no evidence of endometriosis (n = 17, 34%). IL-2, IL-4, and Monocyte chemotactic protein 1 concentrations in serum and peritoneal samples were assessed using commercially available human enzyme-linked immunosorbent assay kits. The results were analyzed statistically with the Statistica 8.0 computer software. The value of P < 0.05 was the level of statistical significance. The results in adolescents with endometriosis had significantly higher concentrations of serum IL-4 (3.90 ± 1.58 pg/mL vs. 3.04 ± 1.72 pg/mL; P = 0.04) and peritoneal fluid IL-4 (5.03 ± 8.92 pg/mL vs. 2.74 ± 1.11 pg/mL; P = 0.03), and lower peritoneal fluid IL-2 (92.44 ± 292.75 pg/mL vs. 174.23 ± 389.77 pg/mL; P = 0.01) compared with the control. In a receiver-operating characteristic analysis, serum IL-4 as well as peritoneal fluid IL-2 and IL-4 provided the best discriminative ability between subjects with endometriosis and controls. Using cutoff points for serum IL-4 (3.00 pg/mL), peritoneal fluid IL-2 (21.00 pg/mL) and IL-4 (2.7 pg/mL), relatively high odd ratios were obtained in the prediction of endometriosis in adolescents (3.2; 6.4; 3.3). The Serum IL-4, peritoneal IL-2 and IL-4 provided a good method of discrimination between subjects with endometriosis and controls.

Abstract
AIM The aim of this study was to determine the role of serum and peritoneal interleukin (IL)-6, tumor necrosis factor (TNF)-α and glycodelin A levels as diagnostic markers of endometriosis in adolescent girls. MATERIAL AND METHODS The study encompassed 50 adolescent girls, aged 13-19 years, after menarche and with chronic pelvic pain who qualified for diagnostic laparoscopy. The patients were allocated into two groups: group I (endometriosis group) consisted of subjects with diagnosed endometriosis (n = 33, 66%) and group II (control group) included those whose laparoscopic examinations revealed no evidence of endometriosis (n = 17, 34%). IL-6, TNF-α and glycodelin A concentrations in serum and peritoneal samples were assessed using commercially available human enzyme-linked immunosorbent assay kits. The value of P < 0.05 was adopted as the level of statistical significance. RESULTS Compared with the control group, adolescent girls with endometriosis had significantly higher peritoneal fluid levels of: IL-6 (525.10 ± 1168.53 pg/mL vs 62.96 ± 82.35 pg/mL), TNF-α (5.79 ± 5.60 pg/mL vs 1.68 ± 1.24 pg/mL) and glycodelin A (94.24 ± 60.97 ng/mL vs 53.52 ± 41.43 ng/mL). Peritoneal IL-6, TNF-α and glycodelin A provided a good method of discrimination between subjects with endometriosis and controls. Using cut-off points for peritoneal fluid IL-6 (90.00 pg/mL), TNF-α (3.00 pg/mL) and glycodelin A (60.0 ng/mL), exceptionally high odds ratios (10.2; 14.6; 2.2) were obtained in the prediction of endometriosis in adolescents. CONCLUSIONS At the cut-off value of 3.00 pg/mL, peritoneal TNF-α can be a reliable screening marker for the prediction of endometriosis in adolescents, giving a 14.6-fold higher probability of endometriosis detection in girls with chronic pelvic pain.

Abstract
The etiology of endometriosis, a gynecological disease characterized by the presence of endometrial glands and stroma outside the uterine cavity, is still unknown. Our research group has recently demonstrated the presence of ectopic endometrium in human female fetuses at different gestational ages. In this manuscript we describe four new cases of fetal endometriosis found among a series of 52 female fetuses analyzed at autopsy. The anatomical localization of this ectopic endometrium, and its histological and immunohistochemical characteristics are depicted. We suggest that endometriosis is caused by dislocation of primitive endometrial tissue outside the uterine cavity during organogenesis. The clinical and pathological implications of these findings are discussed.

Abstract
Endometriosis has major physical and psychosocial impacts on teens, as well as long-term implications for their health. The hidden suffering of millions of adolescents worldwide calls on the medical profession to respond, despite the challenges. Given the increasing understanding of adolescent endometriosis, treating adolescents with endometriosis can be a most rewarding experience. Moreover, diagnosing and treating the disease early could prevent more complicated disease later, as well as comorbidities. Helping these girls may save them, their families, and their communities much physical and emotional pain, as well as lessen the huge burden on our health care systems and society.

Abstract
The scientific literature on endometriosis specific to the adolescent population is limited, and the existing data are retrospective and descriptive in nature. It is possible that the disease has a different pathophysiology in adolescents, but little epidemiologic or molecular data exist to support or refute this speculation. In addition, the limited literature does not yet confirm that intervening in the adolescent population prevents long-term sequelae such as pain and infertility as adults. Case-control and cohort studies to identify risk factors, as well as prospective observational and intervention studies to assess treatment outcome, are required to further knowledge about endometriosis in the adolescent population. The scientific literature on endometriosis specific to the adolescent population is limited, and the existing data are retrospective and descriptive in nature. This review summarizes studies that have been done to date and suggests areas for future investigation.

Abstract
Endometriosis is a chronic gynecological disease characterized by the growth of endometrial tissue outside the uterine cavity. Exposure to endocrine disruptors during critical period of development causes long-lasting effects, being the genital system one of the targets. This study describes the effects on female genital system caused by developmental exposure to the endocrine-disrupting chemical bisphenol A (BPA) during pre- and peri-natal development in mice. To this end, timed pregnant Balb-C mice were treated from day 1 of gestation to 7 days after delivery with BPA (100, or 1000 microg/kg/day). After delivery, pups were held for 3 months; then, pelvic organs were analyzed in their entirety and livers of both pups and moms were studied for the presence of BPA. We found in the adipose tissue surrounding the genital tracts of a consistent number of treated animals, endometriosis-like structure with the presence of both glands and stroma and expressing both estrogen receptor and HOXA-10. Moreover, cystic ovaries, adenomatous hyperplasia with cystic endometrial hyperplasia and atypical hyperplasia were significantly more frequent in treated animals respect to the controls. Finally, BPA was found in the livers of exposed moms and female offspring. In conclusion, we describe for the first time an endometriosis-like phenotype in mice, elicited by pre-natal exposition to BPA. This observation may induce to thoroughly reconsider the pathogenesis and treatment of endometriosis, considering the high incidence of endometriosis and the problems caused by associated infertility.

Abstract
OBJECTIVE The aim of this study was to: (1) establish the typical experience of menstruation for senior high school girls and (2) determine how many experience considerable menstrual disturbance that could require further investigation and management of underlying pathology. DESIGN Cross-sectional study. SETTING Senior High Schools in the Australian Capital Territory (ACT), Australia. POPULATION A total of 1051 girls aged between 15 and 19 years. METHODS Data based on a quantitative survey. MAIN OUTCOME MEASURES Self-reports of menstrual bleeding patterns, typical and atypical symptoms and morbidities. RESULTS Typical menstruation in adolescence includes pain (93%), cramping (71%), premenstrual symptoms (96%) and mood disturbance (73%). Highly significant associations were found between increasing severity of menstrual pain, number of menstrual-related symptoms, interference with life activities and school absence. These associations indicate that approximately 25% of the sample had marked menstrual disturbance: 21% experienced severe pain; 26% school absence; 26% suffering five or more symptoms; > or =24% reporting moderate to high interference with four out of nine life activities. Approximately 10% reported atypical symptoms associated with menstruation. Diagnosis of menstrual pathology in the sample was low, even though 33% had seen a GP and 9% had been referred to a specialist. CONCLUSIONS Menstrual pain and symptoms are common in teenagers. Girls indicating moderate to severe pain in association with a high number of menstrual symptoms, school absence and interference with life activities should be effectively managed to minimise menstrual morbidity. Those girls who do not respond to medical management should be considered for further investigation for possible underlying pathology, such as endometriosis.

Abstract
BACKGROUND There are many hypotheses regarding the pathogenesis of endometriosis. Most theories, including retrograde menstruation, require the existence of a uterine structure and endometrial tissue. We report endometriosis with the absence of a uterus. This finding supports the theory of coelomic metaplasia. CASE A 20-year-old with Mayer-Rokitansky-Küster-Hauser syndrome presented with increasing pelvic pain and underwent laparoscopy. Uterine, cervical, vaginal, and tubal agenesis was confirmed. Stage I endometriosis was visualized in the posterior cul-de-sac and destroyed. She received medical therapy for 5 years until she represented with pain and underwent another laparoscopy, at which endometriosis was again identified and destroyed. SUMMARY AND CONCLUSION This case of endometriosis in a patient with complete uterine agenesis supports the theory of coelomic metaplasia.

Abstract
BACKGROUND Endometriosis is a gynecological disease defined by the histological presence of endometrial glands and stroma outside the uterine cavity. Women with endometriosis have an increased risk of different types of malignancies, especially ovarian cancer and non-Hodgkin's lymphoma. Though there are several theories, researchers remain unsure as to the definitive cause of endometriosis. Our objective was to test the validity of the theory of müllerianosis for endometriosis, that is the misplacing of primitive endometrial tissue along the migratory pathway of foetal organogenesis METHODS We have collected at autopsy 36 human female foetuses at different gestational age. We have performed a morphological and immunohistochemical study (expression of oestrogen receptor and CA125) on the pelvic organs of the 36 foetuses included en-block and totally analyzed. RESULTS In 4 out of 36 foetuses we found presence of misplaced endometrium in five different ectopic sites: in the recto-vaginal septum, in the proximity of the Douglas pouch, in the mesenchimal tissue close to the posterior wall of the uterus, in the rectal tube at the level of muscularis propria, and in the wall of the uterus. All these sites are common location of endometriosis in women. CONCLUSION We propose that a cause of endometriosis is the dislocation of primitive endometrial tissue outside the uterine cavity during organogenesis.

Abstract
BACKGROUND Uterus didelphys with obstructed hemivagina and ipsilateral renal agenesis is a rare entity, sometimes referred to as Herlyn-Werner-Wunderlich syndrome (HWW). It usually presents after menarche with progressive pelvic pain, sometimes with regular menses, and a palpable mass due to hemihaematocolpos. The diagnosis is generally made only if the suspicion of this genitourinary syndrome is raised. OBJECTIVE To highlight the imaging diagnostic clues in this rare condition. MATERIALS AND METHODS We report on 11 adolescents with this condition. RESULTS Sonography mostly allowed the correct diagnosis by showing uterovaginal duplication, haematocolpos or haematometrocolpos, and the absence of the ipsilateral kidney. MRI provided more detailed information regarding uterine morphology, the continuity with each vaginal channel (obstructed and nonobstructed), and the bloody nature of the contents. CONCLUSION Early and accurate diagnosis of this syndrome is important so that adequate and prompt surgical therapy (excision of the vaginal septum) can provide relief of pain and prevent further complications. It is also advisable to look for an obstructed Müllerian system whenever a multicystic dysplastic kidney or the absence of a kidney is discovered in a fetus, or girl postnatally.

Abstract
In vertebrates the female reproductive tracts derive from a pair of tubular structures called Mullerian ducts, which are composed of three elements: a canalised epithelial tube, mesenchymal cells surrounding the tube and, most externally, coelomic epithelial cells. Since the first description by Johannes Peter Muller in 1830, the origin of the cells making up the Mullerian duct has remained controversial. We report the results from lineage-tracing experiments in chicken and mouse embryos aimed to provide information of the dynamics of Mullerian duct formation. We show that all Mullerian duct components derive from the coelomic epithelium in both species. Our data support a model of a Mullerian epithelial tube derived from an epithelial anlage at the mesonephros anterior end, which then segregates from the epithelium and extends caudal of its own accord, via a process involving rapid cell proliferation. This tube is surrounded by mesenchymal cells derived from local delamination of coelomic epithelium. We exclude any significant influx of cells from the Wolffian duct and also the view of a tube forming by coelomic epithelium invagination along the mesonephros. Our data provide clues of the underlying mechanism of tubulogenesis relevant to both normal and abnormal development of the female reproductive tract.

Abstract
Endometriosis has long been considered as a disease of women over 30 years old. However, recent data from the literature demonstrated its high incidence in teenagers. Endometriosis in teenagers is generally associated with chronic pelvic pains and cyclical signs are less common than in adults. The persistence of the pain despite an estroprogestative contraception associated with non-steroidal anti-inflammatory drugs is a strong argument for the diagnosis and justifies a laparoscopic exploration. During this laparoscopy, the search for atypical lesions, which are much more common than typical ones, is essential. Biopsies of these lesions is mandatory in every patient to rule out false positives and false negatives which are common in atypical lesions. The aim of the treatment is to improve the pain. The first line of medical treatment is based on the estroprogestative contraception and non-steroidal anti-inflammatory drugs. The prescription of GnRH should be the ultimate solution because the bone reserve increases until the age of 18 to 20. The laparoscopic treatment, when required, should be as complete as possible. Early diagnosis and medical management may prevent the development of the disease. However, further studies in the teenager are essential to improve the current empirical management.

Fertil Steril 2005; 84:67-74. [PMID: 16009159 DOI: 10.1016/j.fertnstert.2005.01.113] [Citation(s) in RCA: 116] [Impact Index Per Article: 6.1] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2004] [Revised: 01/20/2005] [Accepted: 01/20/2005] [Indexed: 11/19/2022]
Abstract
OBJECTIVE To analyze endometrial progesterone receptor (PR) expression in women with endometriosis compared with disease-free women and to assess the impact of in vitro 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) exposure on PR isotype expression. DESIGN Controlled laboratory study. SETTING University medical center. PATIENT(S) Healthy volunteers and women with surgically diagnosed endometriosis. INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) Analysis of in vivo PR-A and PR-B expression in endometrium from women with and without endometriosis. The impact of in vitro TCDD exposure on PR-B/PR-A ratio and cell-specific matrix metalloproteinase (MMP) expression was also determined. RESULT(S) The PR-B/PR-A ratio was lower in endometrial tissues from women with endometriosis compared with normal tissues. A similar ratio was induced in normal stromal cells cocultured with epithelial cells and exposed to TCDD. Disruption of stromal PR expression following TCDD exposure was associated with a failure of P-mediated down-regulation of both stromal-specific pro-MMP-3 and epithelial-specific pro-MMP-7. CONCLUSION(S) Our data suggest that reduced progesterone (P) sensitivity in the endometrium of women with endometriosis may be related to an altered pattern of PR expression. The ability of TCDD to selectively down-regulate stromal PR-B expression and increase MMP expression in both stromal and epithelial cells suggests that exposure to this toxin may negatively impact P-mediated cell-cell communication in the human endometrium.

Hediger ML, Hartnett HJ, Louis GMB. Association of endometriosis with body size and figure. Fertil Steril 2005; 84:1366-74. [PMID: 16275231 PMCID: PMC1343487 DOI: 10.1016/j.fertnstert.2005.05.029] [Citation(s) in RCA: 126] [Impact Index Per Article: 6.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2005] [Revised: 05/04/2005] [Accepted: 05/04/2005] [Indexed: 11/30/2022]
Abstract
OBJECTIVE To determine whether body size and perceived figure, both current and historical, are associated with a diagnosis of endometriosis on laparoscopy. DESIGN Cohort study of consecutively identified patients undergoing laparoscopy for tubal sterilization or as a diagnostic procedure. SETTING Two university-affiliated hospitals. PATIENT(S) A cohort of 84 women aged 18-40 years. Endometriosis was visualized in 32 cases; 52 women (controls) had no visualized endometriosis, including 22 undergoing tubal sterilization and 30 with other gynecologic pathology. INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) Body mass index (BMI, kg/m2) from self-report and perception of body figure were compared for their ability to predict case status (diagnosed endometriosis), using logistic regression models. Longitudinal trends in BMI based on perceived figure at 5-year intervals from age 15 years were compared using mixed linear models. RESULT(S) Based on self-report, women diagnosed with endometriosis were taller, thinner, and had a significantly lower BMI. In this series, cases were more likely to be late maturers (menarche at > or = 14 y) and late to initiate sexual activity (> or = 21 y), and they were less likely to be gravid, parous, and a current smoker. Adjusting for age (in years), being tall (height > or = 68 in), and parity (yes vs. no), a higher current BMI was statistically protective for a diagnosis of endometriosis, regardless of whether BMI was determined by self-report (adjusted odds ratio [AOR] = 0.88, 95% confidence interval [CI] 0.79-0.99) or from perceived figure (AOR = 0.86, 95% CI 0.75-0.99). For every unit increase in BMI (kg/m2), there was an approximate 12%-14% decrease in the likelihood of being diagnosed with endometriosis. In an adjusted repeated measures model, BMI was 21.3 +/- 0.6 kg/m2 (estimate +/- SE) for women with endometriosis, compared with 23.2 +/- 0.4 kg/m2 for the controls, a difference over all ages of -1.9 +/- 0.8 kg/m2. This is a consistent difference of about 10 lb at every age, assuming an average height of about 64.5 in. CONCLUSION(S) In a laparoscopy cohort, women diagnosed with endometriosis were found to have a lower BMI (leaner body habitus), both at the time of diagnosis and historically. That women diagnosed with endometriosis may have a consistently lean physique during adolescence and young adulthood lends support to the suggestion of there being an in utero or early childhood origin for endometriosis.
