Endometriosis in adolescents

Medical Management of Endometriosis in Adolescent and Young Adult Women: A Review of 91 Cases of Biopsy-Confirmed Endometriosis

OBJECTIVE

To characterize contemporary trends in the hormonal management of endometriosis in adolescent and young adult patients with biopsy-proven endometriosis.

METHODS

Retrospective chart review of women aged 14-25 who underwent laparoscopy for pelvic pain with biopsy-proven endometriosis between January 2011 and September 2020 at an academic tertiary hospital system. Final sample included 91 patients with biopsy-confirmed endometriosis.

RESULTS

Combined oral contraceptives (COCs) were the most common initial treatment (64% of patients). Progestin-only formulations (low- and high-dose norethindrone acetate) were offered to younger patients (age 15.9 ± 2.7 years) than those offered COCs (19.9 ± 3.3 years) and levonorgestrel intrauterine devices (LNG-IUDs) (21.9 ± 1.7 years). Current treatments varied widely and included COCs (32%), LNG-IUDs (18%), oral progestins (low- and high-dose norethindrone, medroxyprogesterone) (14%), elagolix (9%), and leuprolide (8%). Oral adjuncts to LNG-IUD were common: usually low- or high-dose norethindrone (37% of patients with an LNG-IUD), but also included progesterone, COCs, and elagolix.

CONCLUSION

Oral progestins, LNG-IUDs, and COCs were the mainstay of initial treatment. Subsequent treatments varied widely and included COCs, LNG-IUDs, oral progestins, elagolix, leuprolide, and combinations of these agents. We observed that most young women switched between therapies, suggesting that a personalized approach is often used to determine treatment plans among the wide range of options currently available. This study helps define the spectrum of treatment regimens for endometriosis in adolescent females.

Surgical Considerations in the Management of Adolescent Endometriosis-An Expert Commentary

Given the complexities and controversies that exist in diagnosing adult endometriosis, as well as optimizing medical and surgical management, it is not surprising that there is even more ambiguity and inconsistency in the optimal surgical care of endometriosis in the adolescent. This collaborative commentary aimed to provide evidence-based recommendations optimizing the role of surgical interventions for endometriosis in the adolescent patient with input from experts in minimally invasive gynecologic surgery, pediatric and adolescent gynecology, and infertility/reproductive medicine.

Understanding Adolescent Gynecological Issues: A Cross-Sectional Study at a Tertiary Care Center

BACKGROUND AND OBJECTIVES

Adolescence is a crucial phase in a woman's life, as it signifies the beginning of her reproductive journey. During this time, there are notable variations in sexual development and a sense of caution that can present challenges for healthcare providers. The rationale for studying adolescent gynecological problems lies in the need to understand and address the unique reproductive health challenges faced by young girls. By investigating these issues, researchers and healthcare professionals can develop effective strategies for prevention, early detection, and treatment of gynecological conditions in adolescents. This knowledge is crucial for promoting the overall well-being and reproductive health of young girls, ensuring they receive appropriate care and support during this critical stage of development. This study focuses on identifying the most common gynecological issues in teenagers, exploring the root causes, examining the available treatment options, and understanding how they are managed at a tertiary care facility.  Methods: This cross-sectional observational study took place at a tertiary care center and focused on gynecological issues in adolescent females who sought care at the gynecology department from January 2016 to December 2022. The study participants were categorized into three groups: early adolescence (10-13 years), middle adolescence (14-16 years), and late adolescence (17-19 years) for analysis. Ethical approval was obtained for this hospital-based research, which involved examining, investigating, and treating the study participants.

RESULTS

Out of the 49,700 new female patients, 2000 (4.02%) fell within the specified age range. The average age of the participants was 16.87±2.16, and the majority of them sought help for menstrual issues (63.45%), followed by abdominal discomfort (15.6%) and vaginal discharge (7.2%). Menstrual disorders were the most common concern, with dysmenorrhea and puberty menorrhagia being prevalent issues. Abdominal pain was caused by various factors, such as urinary tract infections, ovarian tumors, pelvic inflammatory disease, endometriosis, and endometrial tuberculosis. The majority of cases were treated conservatively, with only a small percentage requiring surgical intervention.

CONCLUSION

The significance of early detection and intervention in addressing gynecological issues among adolescents is highlighted in the findings of this research, underscoring the necessity for specialized healthcare services that cater to the specific needs of this demographic. Adolescent gynecology plays a crucial role in safeguarding the reproductive health and overall well-being of young women, emphasizing the importance of seeking assistance proactively.

Deep Infiltrating Endometriosis in Adolescence: Early Diagnosis and Possible Prevention of Disease Progression

Endometriosis has a prevalence of 10% worldwide in premenopausal women. Probably, endometriosis begins early in the life of young girls, and it is commonly diagnosed later in life. The prevalence of deep infiltrating endometriosis (DIE) in adolescence is currently unknown due to diagnostic limits and underestimation of clinical symptoms. Dysmenorrhea is a common symptom in adolescents affected by DIE, often accompanied by dyspareunia and chronic acyclic pelvic pain. Ultrasonography-either performed transabdominal, transvaginal or transrectal-should be considered the first-line imaging technique despite the potential for missed diagnosis due to early-stage disease. Magnetic resonance imaging should be preferred in the case of virgo patients or when ultrasonographic exam is not accepted. Diagnostic laparoscopy is deemed acceptable in the case of suspected DIE not responding to conventional hormonal therapy. An early medical and/or surgical treatment may reduce disease progression with an immediate improvement in quality of life and fertility, but at the same time, painful symptoms may persist or even recur due to the surgery itself. The aim of this narrative review is to report the prevalence of DIE in adolescents, describe the pathogenetic theories and discuss the management in adolescent women, including the challenging road to diagnosis and the treatment alternatives.

The Prevalence of Endometriosis in Patients with Unexplained Infertility

Endometriosis, a systemic ailment, profoundly affects various aspects of life, often eluding detection for over a decade. This leads to enduring issues such as chronic pain, infertility, emotional strain, and potential organ dysfunction. The prolonged absence of diagnosis can contribute to unexplained obstetric challenges and fertility issues, necessitating costly and emotionally taxing treatments. While biopsy remains the gold standard for diagnosis, emerging noninvasive screening methods are gaining prominence. These tests can indicate endometriosis in cases of unexplained infertility, offering valuable insights to patients and physicians managing both obstetric and non-obstetric conditions. In a retrospective cross-sectional study involving 215 patients aged 25 to 45 with unexplained infertility, diagnostic laparoscopy was performed after unsuccessful reproductive technology attempts. Pathology results revealed tissue abnormalities in 98.6% of patients, with 90.7% showing endometriosis, confirmed by the presence of endometrial-like glands and stroma. The study underscores the potential role of endometriosis in unexplained infertility cases. Although the study acknowledges selection bias, a higher than previously reported prevalence suggests evaluating endometriosis in patients who have not responded to previous reproductive interventions may be justified. Early detection holds significance due to associations with ovarian cancer, prolonged fertility drug use, pregnancy complications, and elevated post-delivery stroke risk.

Evaluation and Management of Endometriosis in the Adolescent

Endometriosis is a chronic condition, with debilitating symptoms affecting all ages. Dysmenorrhea and pelvic pain often begin in adolescence, affecting school, daily activities, and relationships. Despite the profound burden of endometriosis, many adolescents experience suboptimal management and significant delay in diagnosis. The symptomatology and laparoscopic findings of endometriosis in adolescents are often different than in adults, and the medical and surgical treatments for adolescents may differ from those for adults as well. This Narrative Review summarizes the diagnosis, evaluation, and management of endometriosis in adolescents. Given the unique challenges and complexities associated with diagnosing endometriosis in this age group, it is crucial to maintain a heightened level of suspicion and to remain vigilant for signs and symptoms. By maintaining this lower threshold for consideration, we can ensure timely and accurate diagnosis, enabling early intervention and improved management in our adolescent patients.

Evidence of shared genetic factors in the etiology of gastrointestinal disorders and endometriosis and clinical implications for disease management

In clinical practice, the co-existence of endometriosis and gastrointestinal symptoms is often observed. Using large-scale datasets, we report a genetic correlation between endometriosis and irritable bowel syndrome (IBS), peptic ulcer disease (PUD), gastro-esophageal reflux disease (GORD), and a combined GORD/PUD medicated (GPM) phenotype. Mendelian randomization analyses support a causal relationship between genetic predisposition to endometriosis and IBS and GPM. Identification of shared risk loci highlights biological pathways that may contribute to the pathogenesis of both diseases, including estrogen regulation and inflammation, and potential therapeutic drug targets (CCKBR; PDE4B). Higher use of IBS, GORD, and PUD medications in women with endometriosis and higher use of hormone therapies in women with IBS, GORD, and PUD, support the co-occurrence of these conditions and highlight the potential for drug repositioning and drug contraindications. Our results provide evidence of shared disease etiology and have important clinical implications for diagnostic and treatment decisions for both diseases.

How to Manage Endometriosis in Adolescence: The Endometriosis Treatment Italian Club Approach

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.

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.

Efficacy of Dienogest in Adolescent Endometriosis: A Narrative Review

Teenage endometriosis is seen as a chronic condition that can worsen if untreated. Treatment objectives include relief of symptoms, prevention of disease development, and preservation of future fertility. In many regions, dienogest (DNG), an oral progestin, has emerged as a key treatment in suppressing endometriosis. The usage of DNG for endometriosis in adolescents was researched in papers published between 2015 and 2022 using PubMed and Google Scholar. A thorough search of all identified studies' reference lists and previously published literature reviews was carried out. The study's nature and geographic scope were not restricted. After reviewing these publications, the authors decided on which ones were the most pertinent in light of their personal experiences. The final study consisted of 14 studies that satisfied inclusion requirements. The trials showed that taking DNG 2 mg daily efficiently lowers endometriotic lesions, eases painful endometriosis symptoms, and improves quality-of-life indicators. In most of these investigations, DNG was shown to be safe and tolerated, with predictable and moderate side effects, good patient compliance rates, and low withdrawal rates. Although endometrioma did not enlarge while receiving treatment, significant regression was not typical. Overall, the studies found that DNG is safe and effective in reducing symptoms of endometriosis in adolescents.

You Can Change a Girl's Life Today: The Truth About Periods and Endometriosis

While endometriosis, a condition where tissue growing outside the uterus causes pain and infertility, is generally widespread among teenage girls and women, it is often misdiagnosed leading to a delay in treatment while the symptoms and damage from the disease increase. This article uses a case study to illustrate the signs and symptoms of endometriosis in a teenage girl, while also discussing many factors surrounding the issue such as the incidence, disease burden, medical research and women, reasons for diagnostic delay, and the current recommended treatments. School nurses are in the unique position to identify young girls and adolescents who are presenting with painful periods or other symptoms possibly associated with endometriosis and can become advocates for the next generation of patients.

Psychiatric Symptoms in Patients with Cerebral Endometriosis: A Case Report and Literature Review

Endometriosis is a systemic medical condition characterized by endometrial tissue that is abnormally implanted in extrauterine sites, including the central nervous system. In this article, we reported the case of a patient with presumed cerebral endometriosis who was diagnosed with bipolar disorder and panic disorder and systematically reviewed the literature for previously reported neuropsychiatric symptoms in patients with cerebral and cerebellar endometriosis. The PubMed, Scopus, and Web of Science bibliographic databases were searched according to the PRISMA guidelines. Seven previous case reports were found and described. While neurological disturbances dominated the clinical picture in the cases retrieved from the literature, our patient represented the first case to show both neurological and psychiatric manifestations. Atypical features of bipolar disorder including chronic mood instability, mixed episodes, and excitatory interepisodic symptoms were highlighted. During the neuropsychological evaluation, a dysexecutive profile consistent with frontal lobe pathology was evidenced. We hypothesized that the course and features of the illness were largely influenced by the presence of documented brain lesions compatible with endometrial implants, especially in the frontal region. Accordingly, patients with endometriosis who exhibit neurological as well as mental symptoms should be investigated for cerebral lesions.

Transvaginal ultrasound evaluation of the pelvis and symptoms after laparoscopic partial cystectomy for bladder endometriosis

Objective:

To evaluate transvaginal sonography (TVS) findings after laparoscopic partial cystectomy for bladder endometriosis and to correlate postsurgical ultrasound findings with symptoms.

Material and Methods:

A retrospective study including women who underwent laparoscopic partial cystectomy for bladder endometriosis. Within 12 months after surgery, TVS examination was conducted in all patients to evaluate the bladder morphology, and the presence of any postsurgical sonographic findings of the pelvis. Painful symptoms were assessed using a visual analogue scale.

Results:

A total of 40 women were included. At the follow-up visit, 25 patients were receiving medical treatment while 15 had declined post-surgical therapy and had tried to conceive. The presence of bladder deep-infiltrating endometriosis (DIE) was found in nine (22.5%), fibrotic thickening of the bladder wall was found in 15 (37.5%), and normal bladder morphology was observed in 16 (40%). There was a correlation between anterior adenomyosis and bladder DIE, and fibrotic thickening of the bladder. Patients with TVS signs of bladder DIE and anterior adenomyosis suffered more dysmenorrhea and dysuria than patients with normal bladder.

Conclusion:

Post-operative TVS can detect the alteration of pelvis and could explain the causes of the persistence of symptoms.

Height and pelvic lesion number: Do they have a positive relationship with postoperative recurrence in adolescent endometriosis?-A retrospective clinical analysis of 89 adolescent endometriosis in China

BACKGROUND

Adolescent endometriosis is a special type of endometriosis. Its diagnosis is often delayed. This study aimed to share the treatment experience of adolescent endometriosis and analyze the clinical manifestation, clinical stage, and risk factors of postoperative recurrence in China.

METHODS

Eighty-nine cases of adolescent endometriosis over 7 years in a single institution were reviewed. Demographic, clinical outcome measures were collected.

RESULT

The cumulative incidence rates of postoperative recurrence at years 1, 2, 3, 4, and 5 were 13.2%, 15.09%, 16.98%, 20.75%, and 20.75%, respectively. The risk factors associated with postoperative recurrence were disease stage, number of lesions, and height. In multivariate analysis, the independent risk factors of postoperative recurrence were height (RR: 1.132, 95% CI: 1.018-1.260) and the number of pelvic lesions (three or more, RR: 4.202, 95% CI: 1.013-17.433).

CONCLUSION

Taller patients and those who had multiple lesion sites (≥3) should receive more attention, because they have a higher possibility of relapse after surgery than their counterparts. This finding can guide the postoperative treatment of adolescent patients with endometrioma.

Cohort profile: The Endometriosis pain QUality aftEr Surgical Treatment (EndoQUEST) Study

Endometriosis affects reproductive-aged females and varies considerably in terms of symptom presentation, morphologic features, and treatment response. Most studies investigating symptom recurrence after an endometriosis-related surgery have been conducted among adults. The Endometriosis pain QUality aftEr Surgical Treatment (EndoQUEST) Study was established to assess characteristics and biomarkers that are associated with pain remediation and improved quality of life after an endometriosis-related surgery among adolescents and young adults. This paper describes the EndoQUEST methodology, summarizes baseline descriptive factors, and compares characteristics by participant retention status. We enrolled 100 surgically-confirmed endometriosis participants aged 12–23 years who provided questionnaire data on reproductive and behavioral factors, pain characteristics and quality of life at three time points; before surgery, 6 weeks to 26 weeks after surgery, and 1 year after surgery. Among these 100 participants, 88 provided blood and/or saliva at all three time points, while 12 provided blood and/or saliva samples only before surgery and 6 to 26 weeks after surgery. There was little evidence of lost to follow-up at 1 year after surgery due to pain symptoms, as pain and quality of life characteristics were similar between participants who completed the questionnaire 1 year after surgery and those who did not. Analyses utilizing these longitudinal data will advance personalized treatment decision making for adolescents and young adults with endometriosis.

Medical and Behavioral Aspects of Adolescent Endometriosis: A Review of the Literature

The majority of young women will experience discomfort associated with menstrual cycles and miss out on education and social opportunities. Endometriosis, the presence of endometrial glands and stroma outside of uterus, is the most common cause of secondary dysmenorrhea and characterized by pain despite treatment with nonsteroidal anti-inflammatory drugs and hormonal agents. The true prevalence of adolescent endometriosis is not clear. Delay in diagnosis leads to persistent pain, affects quality of life, and potentially contributes to disease progression and subfertility. A laparoscopic diagnosis is the gold standard, but the surgical appearance may differ from adults, as endometriotic lesions are usually red or clear, making their identification a challenge for gynecologists who are unexperienced with endometriosis in adolescents. A personalized medical–surgical treatment is regarded as the most effective therapeutic strategy to achieve remission of symptoms, suppress disease progression, and protect future fertility. Studies have demonstrated how adolescent endometriosis negatively affects patients’ quality of life and psychosocial functioning. Development of therapeutic interventions targeting psychosocial function and quality of life is imperative for adolescent patients.

Reduced Activity and Quality of Life in Women Soldiers with Heavy Menstrual Bleeding and Dysmenorrhea

STUDY OBJECTIVE

The aim of the study was to examine the effect of heavy menstrual bleeding (HMB) and dysmenorrhea on daily activity and quality of life (QoL) in young women engaged in demanding activities.

DESIGN

Cross-sectional study.

PARTICIPANTS

A total of 422 Israeli women soldiers in combat and non-combat roles.

INTERVENTIONS

Participants were asked to provide consent and to complete study questionnaires.

MAIN OUTCOME MEASURES

A pictorial bleeding assessment chart (PBAC), visual analog scale (VAS), verbal multidimensional scoring system for assessment of dysmenorrhea, and approved Hebrew-translated age-appropriate Pediatric Quality of Life Inventory (PedsQL).

RESULTS

HMB (PBAC >100) and severe HMB (PBAC >185) were demonstrated in 181 (50%) and 96 (26%) participants, respectively. A high PBAC score was recorded in 20% who answered "no" or "unknown" in the questionnaire on having HMB. Mild, moderate, and severe dysmenorrhea were demonstrated in 80 (21.5%), 115 (31%), and 142 (38%) participants, respectively. The prevalence of HMB and dysmenorrhea was similar in soldiers in combat and non-combat roles. Diagnosis of HMB was related to the lower fitness-for-service score, history of bleeding, and dysmenorrhea. Daily activity and QoL were both affected by the severity of HMB and dysmenorrhea.

CONCLUSION

Underdiagnosis of HMB and dysmenorrhea results from a combination of unawareness from the women's side and inattention from the system. In an era of female empowerment, each woman should be at the optimal physiological and psychological level to start her career; thus, addressing the menstrual burden and providing effective treatment is needed in the military scenario and other settings with demanding activities.

Genetic Relationship Between Endometriosis and Melanoma

Epidemiological studies have observed that risk of endometriosis is associated with history of cutaneous melanoma and vice versa. Evidence for shared biological mechanisms between the two traits is limited. The aim of this study was to investigate the genetic correlation and causal relationship between endometriosis and melanoma. Summary statistics from genome-wide association meta-analyses (GWAS) for endometriosis and melanoma were used to estimate the genetic correlation between the traits and Mendelian randomization was used to test for a causal association. When using summary statistics from separate female and male melanoma cohorts we identified a significant positive genetic correlation between melanoma in females and endometriosis (rg = 0.144, se = 0.065, p = 0.025). However, we find no evidence of a correlation between endometriosis and melanoma in males or a combined melanoma dataset. Endometriosis was not genetically correlated with skin color, red hair, childhood sunburn occasions, ease of skin tanning, or nevus count suggesting that the correlation between endometriosis and melanoma in females is unlikely to be influenced by pigmentary traits. Mendelian Randomization analyses also provided evidence for a relationship between the genetic risk of melanoma in females and endometriosis. Colocalization analysis identified 27 genomic loci jointly associated with the two diseases regions that contain different causal variants influencing each trait independently. This study provides evidence of a small genetic correlation and relationship between the genetic risk of melanoma in females and endometriosis. Genetic risk does not equate to disease occurrence and differences in the pathogenesis and age of onset of both diseases means it is unlikely that occurrence of melanoma causes endometriosis. This study instead provides evidence that having an increased genetic risk for melanoma in females is related to increased risk of endometriosis. Larger GWAS studies with increased power will be required to further investigate these associations.

Characterizing the impact of menstrual and pelvic health disorders in a convenience sample of women in Barbados

Objective:

To describe the impact of menstrual and pelvic health disorders on a sample of Barbadian women living with one or more disorders.

Design and methods:

Responses from a survey taken online by a sample of women living in Barbados (⩾18 years) were assessed. Variables collected included, age, disorder(s) diagnosed, and symptoms. The Work Productivity and Activity Impairment (WPAI) Questionnaire: Specific Health Problem, was administered to measure impact on work and other activities. T-tests, chi- square tests, odds ratios, ANOVA, and multivariate analysis were conducted to estimate the associations between patient characterization, disorder characteristics and outcomes.

Results:

A total of 247 unique responses were received and after data were reviewed 192 responses (77.7%) from this convenience sample were analyzed. Polycystic Ovary Syndrome was the most frequently reported diagnosis (34.7%). The most frequently reported symptom was fatigue (53%). There was an OR of 2.17 (95% CI 0.54–8.74) of missing work due to menorrhagia and 2.60 (95% CI: 1.31–5.17) of missing work if diagnosed with endometriosis. The WPAI revealed endometriosis to be the condition with the most substantial impact on work in the subgroup of persons with one diagnosis, with presenteeism of 49.2%, absenteeism of 13.3% and an impact on other activities of 56.4%.

Conclusion:

Pelvic and menstrual disorders have a significant impact on productivity and other activities of Barbadian women. More research is necessary to elucidate the impacts of menstrual and pelvic disorders and treatments on patient outcomes.

Combating Diagnostic Delay of Endometriosis in Adolescents via Educational Awareness: A Systematic Review

Endometriosis occurs in approximately 10% of adult women worldwide; however, it is commonly under- or misdiagnosed in adolescents. The purpose of this study was to analyze existing scientific literature for reasons for diagnostic delay of endometriosis and to determine how education regarding endometriosis could be improved. An integrative review was conducted based on articles published between December 1980 and December 2020. Suitable articles were identified from the MEDLINE/PubMed databases, using relevant terms. Eligible studies included discussion on potential causes of diagnostic delay of endometriosis in the adolescent population. Data were extracted from eligible publications and qualitative synthesis was used. The 27 articles included in the study revealed several primary reasons for the delay, such as a physician and/or patient knowledge gap, normalization by physician and patient, lack of research, and physician resistance. Strategies to lessen diagnostic delay of endometriosis in adolescents must include integrated actions by educators and healthcare providers to improve health literacy and awareness of common causes of pelvic pain in this age group.

Adolescent Endometriosis

Importance

Endometriosis is a major health concern in the adolescent population and significantly impacts daily physical and psychosocial functioning. Endometriosis can have differing presentations in this population, and the diagnosis often involves long delays and multiple visits to specialists.

Objective

The aim of this review is to discuss adolescent endometriosis, factors specific to this population, accurate diagnosis, and evidence-based surgical and medical management.

Evidence Acquisition

Computerized searches on the topic of endometriosis and adolescent endometriosis were completed. References from identified sources were then searched manually to allow for a thorough review. Data from relevant sources were synthesized to create the review.

Results

The literature supports endometriosis as a frequent cause of secondary dysmenorrhea. The characteristics of adolescents with endometriosis are shown to differ from those of adults. Initial medical therapy includes nonsteroidal anti-inflammatory drugs and combined hormonal contraceptives, but laparoscopy does have a role in the adolescent population, particularly those who have inadequate response to these treatments. Adolescent endometriosis may have a different appearance and be of all stages. Medical therapies are similar to that of the adult population; however, the benefits of medical and surgical management must be tailored to the adolescent patient.

Conclusions and Relevance

Adolescent endometriosis is likely a more prevalent cause of dysmenorrhea than currently appreciated. A high index of suspicion combined with recognition of risk factors and history-based markers of endometriosis may help identify adolescent endometriosis earlier and avoid delays in diagnosis. Expert opinion supports earlier laparoscopic evaluation in patients with symptoms unresponsive to oral medications, those who have failed initial medical therapy, or those who have evidence of deeply invasive disease, such as an endometrioma. Surgeons should be familiar with the unique appearance of lesions in the adolescent and understand the evidence as it relates to surgical therapy. Postoperative medical management is generally advocated by many, although the efficacy remains unclear at present.

Endometriosis in adolescent and young women

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.

The Importance of a Multi-Disciplinary Approach to the Endometriotic Patients: The Relationship between Endometriosis and Psychic Vulnerability

Endometriosis is a chronic inflammatory condition, which is distinguished by the presence of the endometrial-like glands and stroma outside the uterine cavity. Pain and infertility are the most commonly expressed symptoms, occurring in 60% and 40% of cases, respectively. Women with endometriosis, especially those with pelvic pain, also have a greater vulnerability to several psychiatric disorders. There is, in particular, a tendency to contract affective or anxiety disorders as well as panic-agoraphobic and substance use disorders. Endometriosis with pelvic pain, infertility and psychic vulnerability usually leads to disability and a markedly lower quality of life for women of reproductive age. Thus, the burden of endometriosis is not limited to the symptoms and dysfunctions of the disease; it extends to the social, working and emotional spheres, leading to a severe impairment of global functioning. An analysis of scientific literature revealed a close relationship between specific temperamental traits, the expression of several psychiatric symptoms, chronicity of pain, risk of substance use and lower probability of a positive outcome. Endometriosis symptoms and the impact of related psychological consequences, increased vulnerability and the possible onset of psychiatric symptoms may influence coping strategies and weaken resilience, so triggering a vicious cycle leading to a marked deterioration in the quality of life. A multidisciplinary approach consisting of a medical team composed of gynecologists, psychologists, psychiatrists, experts in Dual Disorder, algologists and sexologists, would guarantee the setting of a target and taking the best decision on a personalized treatment plan. That approach would allow the prompt detection of any psychopathological symptoms and improve the endometriosis-related physical symptoms, bringing a healthier quality of life and a greater likelihood of a positive outcome.

Adolescence and endometriosis: symptoms, ultrasound signs and early diagnosis

OBJECTIVE

To evaluate the ultrasonographic presence of different forms of endometriosis and the associated clinical symptoms in adolescent women.

DESIGN

Retrospective observational study.

SETTING

University hospital.

PATIENT(S)

Two hundred and seventy women aged 12-20 years referred to the gynecologic ultrasound unit from January 2014 to June 2019.

INTERVENTION(S)

Two-dimensional, three-dimensional, and power Doppler ultrasound (US) pelvic examination (transvaginal or transrectal in pre-sexually active adolescents) were performed in all included adolescents. Medical history was collected for each patient before the scan.

MAIN OUTCOME MEASURE(S)

All possible locations of endometriosis evaluated and recorded using a dedicated ultrasound mapping sheet and severity of painful symptoms evaluated through a visual analogue scale (VAS).

RESULT(S)

Dysmenorrhea was detected in 147 (54.4%) of 270 patients and heavy menstrual bleeding in 76 (28.1%) of 270. At least one ultrasound feature of endometriosis was identified in 36 (13.3%) of 270 cases. Ovarian endometriomas were found in 22 (11%) patients, adenomyosis in 16 (5.2%), and deep infiltrating endometriosis (DIE) in 10 (3.7%). Ultrasound signs of endometriosis were found in 21% of adolescents who reported dysmenorrhea and 33% with dyspareunia. The presence of DIE at ultrasound was associated with bowel symptoms in 33% of patients and associated with dyspareunia in 25% of patients.

CONCLUSION(S)

The detection rate of pelvic endometriotic lesions at ultrasound was 13%. The rates of dysmenorrhea, dyspareunia and heavy menstrual bleeding in adolescents with endometriosis ultrasound signs were statistically significantly higher compared with those without. In patients with dysmenorrhea, the detection rate of pelvic endometriosis at ultrasound increased to 20%. Professionals involved with teens should be aware of the clinical presentation of endometriosis to reduce the delay between the onset of symptoms and the diagnosis, referring these young women to dedicated centers.

Adolescent Endometriosis: An Update

Endometriosis is the leading pathologic cause of dysmenorrhea and chronic pelvic pain among adolescents. The appearance of endometriosis in adolescents may be different from that in female adults, resulting in delayed recognition and intervention. This article addresses the epidemiology, pathophysiology, clinical presentation, diagnosis, and management of endometriosis in the adolescent.

Strengthening health care worker engagement with early adolescence in low- and middle-income countries: an overdue area for action

The very young adolescent population (ages 10-14) is currently under-served by health care systems, particularly in low- and middle-income countries. Although there is a substantial and growing effort to reach adolescents with the health services and commodities they need, such efforts often overlook the period of early adolescence given this population's lower vulnerability to risk-taking behaviors. However, early adolescence is a period of significant change, with the onset of puberty introducing physiological, emotional, and social changes in girls' and boys' lives. This period also represents a time of intensifying gendered norms, and the transition of youth from childhood focused health care (e.g. deworming programs, nutrition interventions) to additional mid- and older adolescent related care [e.g. human papilloma virus (HPV) vaccine, and contraceptive provision). Strengthening young adolescents' engagement with health care workers around preventative and promotive health behaviors could have profound impacts on their health and wellbeing, which in turn could have cascading effects across the course of their lives. Critically, young adolescents would gain trust in health care systems, and be more likely to return when significant health issues arise later in adolescence or adulthood. Such an effort requires sensitizing health care workers and building their capacity to respond to young adolescents' unique needs, by defining a package of actions that they are mandated to provide, training them, providing them with desk reference tools, and putting in place systems to provide supportive supervision and collaborative learning on the one hand, and encouraging caregivers to connect their pubescent-aged boys and girls with the health care system, on the other hand. This paper presents an argument for increased focus in particular on building attitudes and capacities of health care workers on engaging with early adolescents, applying Principle 3 of the Society of Adolescent Medicine's position paper entitled "Health Care Reform and Adolescents."

Diagnosis and Management of Heavy Menstrual Bleeding and Bleeding Disorders in Adolescents

IMPORTANCE

Heavy menstrual bleeding is a common cause of anemia and reduced quality of life in adolescents. There is a higher prevalence of bleeding disorders in girls with heavy menstrual bleeding than in the general population. Pediatricians should be comfortable with the initial evaluation of heavy menstrual bleeding and the indications for referral to subspecialty care.

OBSERVATIONS

The most common cause of heavy menstrual bleeding in adolescents is ovulatory dysfunction, followed by coagulopathies. The most common inherited bleeding disorder is von Willebrand disease, and its incidence in adolescents with heavy menstrual bleeding is high. Distinguishing the etiology of heavy menstrual bleeding will guide treatment, which can include hemostatic medications, hormonal agents, or a combination of both. Among hormonal agents, the 52-mg levonogestrel intrauterine device has been shown to be superior in its effect on heavy menstrual bleeding and is safe and effective in adolescents with bleeding disorders.

CONCLUSIONS AND RELEVANCE

Anemia, need for transfusion of blood products, and hospitalization may be avoided with prompt recognition, diagnosis, and treatment of heavy menstrual bleeding, especially when in the setting of bleeding disorders. Safe and effective treatment methods are available and can greatly improve quality of life for affected adolescents. A multidisciplinary approach to the treatment of girls with bleeding disorders and history of heavy menstrual bleeding is optimal.

Endometriosis and pain in the adolescent- striking early to limit suffering: A narrative review

Endometriosis, a condition in which uterine tissue grows outside the uterus, is a debilitating disease, affecting millions of women and costing the United States approximately $78 billion annually in pain- related disability. It is also the leading cause of chronic pelvic pain (CPP), which is often unresponsive to existing treatments. Adolescent women with the disease are at particular risk as there are often significant diagnostic delays, which in turn can exacerbate pain. Research and treatment guidelines for adolescents with endometriosis are largely based on studies for adult women due to the limited number of studies focusing on adolescents. The current paper critically reviews the literature as it pertains to endometriosis pathophysiology, mechanisms contributing to CPP, and treatment implications and recommendations with a focus on gaps related to adolescents.

Abnormal uterine bleeding in adolescents: ultrasound evaluation of uterine volume

OBJECTIVE

To evaluate ultrasonographic measurements of internal genitalia in girls suffering from abnormal uterine bleeding (AUB) and to compare the appearances with those of healthy girls. DESIGN Prospective case - control study.

METHODS

One hundred and five not sexually active adolescent girls were enrolled - 67 patients were suffering from AUB and there were 38 healthy peers. The groups did not differ in chronological age, or in postmenarcheal age. All girls underwent assessment of their history, clinical data and transabdominal pelvic ultrasound to evaluate their uterus and ovaries. In order to avoid the impact of endometrium cycle fluctuations, the uterine volume was calculated including and excluding its thickness.

RESULTS

The uterine volume among the girls suffering from AUB was significantly larger than in the control group. The mean uterine volume including endometrium in the study and control groups was 63.2 ± 24.8 and 47.8 ± 17.5 cm³, respectively (p=.001), and excluding the endometrium was 34.7 ± 13.1 and 29.1 ± 13.8 cm³ (p=.043). We did not find any significant difference in ovarian volume between the groups.

CONCLUSIONS

The girls in the AUB group have significantly larger uterine volume than healthy girls. This finding does not depend on endometrial thickness.

Endometriosis biomarkers: Will codevelopment in academia–industry partnerships result in new and robust noninvasive diagnostic tests?

Endometriosis is an important gynecological disease, affecting 10% of reproductive age women, and associated with pain, infertility, reduced quality of life, and high health economic cost. Except for ultrasound detection of ovarian endometriotic cysts, the gold standard for diagnosis is laparoscopy, leading to diagnostic delays of 5–10 years. Accurate noninvasive biomarkers are needed, especially for symptomatic women with a normal gynecological ultrasound, to triage them towards medical or surgical treatment and to monitor their treatment outcome. Such biomarkers are not available today, largely because the research focus has been on discovery, not on reproducibility and validation. Academia/industry partnerships can move this field forward by validation of promising markers, consensus on endometriosis phenotypes/controls and desirable accuracy (sensitivity/specificity). Such partnerships should increase the quality and reproducibility of target discovery work and foster global consensus on the use of relevant preclinical/animal models, if they are managed with complete (financial) transparency and with the aim to translate innovation into products benefiting patients. It is essential that mutual objectives are clarified between industry and academia partners including intellectual property policy, critical decision points, funding agreements, milestones and timelines, with a clear strategy for project termination/change of strategy, a restriction on publications till new discoveries have been patented, considering that a minority of novel findings can be translated into new therapeutic targets, diagnostics, or marketed products.

Endometriosis in adolescents

PURPOSE OF REVIEW

The current article addresses recent literature regarding the diagnosis and management of endometriosis in adolescents.

RECENT FINDINGS

An increasing body of literature suggests that advanced-stage endometriosis (revised scoring system of the American Society for Reproductive Medicine Stage III or IV) and deeply invasive endometriosis are relatively common in adolescents. There remains limited data on the efficacy of postoperative hormonal management of endometriosis in the adolescent population.

SUMMARY

Strong consideration should be made for surgical diagnosis of endometriosis in adolescents with pelvic pain, including noncyclic pain, with a concurrent family history of endometriosis and personal history of atopic disease. More research is needed regarding the benefits of the routine use of hypoestrogenic and other hormonal agents in the prevention of disease progression and long-term sequela in adolescents with endometriosis.

A focus on the distinctions and current evidence of endometriosis in adolescents

Endometriosis (EM) occurring in adolescents presents distinct clinical and histologic characteristics compared to the disease in women. Because the symptoms of EM are nonspecific, often overlapping with those experienced in a range of gynecological and gastrointestinal conditions, the process of reaching a diagnosis of EM is often delayed. The diagnosis of EM is suspected depending on the history and the symptoms and signs, is corroborated by physical examination and imaging techniques, and is finally proved by histological examination of specimens collected during laparoscopy. Currently, there is insufficient evidence to make strong recommendations for management in adolescents who may have EM. This short report reviews some peculiarities of EM in adolescents and provides an update of recent knowledge of the diagnosis and treatment of EM. We hope that the present contribution may help to bring more attention to the clinical diagnosis of EM and consequently aid in decreasing diagnostic delay.

Endometriosis in Adolescent and Young Girls: Report on a Series of 55 Cases

STUDY OBJECTIVE

The aim of this retrospective study was to evaluate endometriosis in adolescent and young girls and further to review the menstrual, reproductive characteristics, and risk factors.

DESIGN AND SETTING

We reviewed the medical records of adolescent and young girls with endometriosis from 2 different countries. Data were collected and analyzed from charts of 900 patients with endometriosis.

PARTICIPANTS AND INTERVENTIONS

Fifty-five female adolescents aged between 13 and 21 years (mean age 18.3 years) participated in our series. This study was conducted in the Obstetric and Gynecology Department of Venizeleio General Hospital of Crete and involved all patients diagnosed with endometriosis between 1996 and 2016.

MAIN OUTCOME MEASURES

Statistical methods included χ² and Mann-Whitney U test.

RESULTS

Of 900 patients with endometriosis we found 55 female adolescents (6.1%). The mean age was 18.3 ± 2.3 years, significantly younger compared with the advanced endometriosis patients (32.7 ± 7.2; P < .001). Regarding the menstrual reproductive and others characteristics, we observed several differences in adolescent young girls compared with the advanced age endometriosis group. The factors associated with an increased risk for young women include age at menarche, dysmenorrhea, history of asthma, and a positive family history of endometriosis. Additionally, we report on 16 of 55 (32%) adolescent women with endometriosis and congenital malformations (P < .01) and 5 patients who were diagnosed with dry eye syndrome.

CONCLUSION

There is an association between endometriosis in adolescent and young women and risk factors including early menarche, early onset of dysmenorrhea, history of asthma, previous surgical procedures, obstructive genital anomalies, and family history of endometriosis.

Endometriosis: Epidemiology, Diagnosis and Clinical Management

Purpose of review

Endometriosis is a disease of adolescents and reproductive-aged women characterized by the presence of endometrial tissue outside the uterine cavity and commonly associated with chronic pelvic pain and infertility. Here we review the epidemiology of endometriosis as well as potential biomarkers for detection and with the goal of highlighting risk factors that could be used in combination with biomarkers to identify and treat women with endometriosis earlier..

Recent findings

Early age at menarche, shorter menstrual length, and taller height are associated with a higher risk of endometriosis while parity, higher body mass index (BMI) and smoking are associated with decreased risk. Endometriosis often presents as infertility or continued pelvic pain despite treatment with analgesics and cyclic oral contraceptive pills.

Summary

Despite a range of symptoms, diagnosis of endometriosis is often delayed due to lack of non-invasive, definitive and consistent biomarkers for diagnosis of endometriosis. Hormone therapy and analgesics are used for treatment of symptomatic endometriosis. However, the efficacy of these treatments are limited as endometriosis often recurs. In this review, we describe potential diagnostic biomarkers and risk factors that may be used as early non-invasive in vitro tools for identification of endometriosis to minimize diagnostic delay and improve reproductive health of patients.

Endometriosis in Adolescents: A Systematic Review

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.

Important considerations in adolescent health maintenance: long-acting reversible contraception, human papillomavirus vaccination, and heavy menstrual bleeding

PURPOSE OF REVIEW

The present article addresses recent research related to three key facets of adolescent preventive care and health maintenance: long-acting reversible contraception, human papillomavirus vaccination, and heavy menstrual bleeding.

RECENT FINDINGS

Recent studies suggest that long-acting reversible contraception use results in significantly lower rates of unintended pregnancies, and is well tolerated by nulliparous adolescent females. Additionally, a strong recommendation from a pediatric primary care provider is extremely effective in ensuring human papillomavirus vaccination prior to sexual debut. Finally, heavy menstrual bleeding is often under-recognized in adolescents, and evaluation and treatment of these patients are variable.

SUMMARY

Based on the recent literature findings, the pediatric primary care provider should be encouraged to, first, recommend long-acting reversible contraception for prevention of unintended pregnancy in adolescent patients; second, strongly endorse vaccination to protect against human papillomavirus in all patients prior to sexual debut; and, third, screen adolescent females for signs and symptoms of heavy menstrual bleeding.

Overall Adiposity, Adipose Tissue Distribution, and Endometriosis: A Systematic Review

BACKGROUND

Endometriosis has been associated with a lean body habitus. However, we do not understand whether endometriosis is also associated with other characteristics of adiposity, including adipose tissue distribution and amount of visceral adipose tissue (VAT; adipose tissue lining inner organs). Having these understandings may provide insights on how endometriosis develops-some of the physiological actions of adipose tissue differ depending on tissue amount and location and are related to proposed mechanisms of endometriosis development.

OBJECTIVES

The aim of this study was to review the literature regarding overall adiposity, adipose tissue distribution and/or VAT, and endometriosis.

METHODS

We reviewed and synthesized studies indexed in PubMed and/or Web of Science. We included studies that had one or more measures of overall adiposity, adipose tissue distribution, and/or VAT and women with and without endometriosis for comparison. We summarized the findings and commented on the methods used and potential sources of bias.

RESULTS

Of 366 identified publications, 19 (5.2%) were eligible. Two additional publications were identified from reference lists. Current research included measures of overall adiposity (e.g., body figure drawings) or adipose tissue distribution (e.g., waist-to-hip ratio), but not VAT. The weight of evidence indicated that endometriosis was associated with low overall adiposity and with a preponderance of adipose tissue distributed below the waist (peripheral).

DISCUSSION

Endometriosis may be associated with being lean or having peripherally distributed adipose tissue. Well-designed studies with various sampling frameworks and precise measures of adiposity and endometriosis are needed to confirm associations between adiposity measures and endometriosis and delineate potential etiological mechanisms underlying endometriosis.

Long-Term Clinical Outcomes in Diabetic Rhesus Macaques (Macaca mulatta) Treated with Medroxyprogesterone Acetate for Endometriosis

Depot medroxyprogesterone acetate (DMPA) is a common medical treatment for endometriosis in NHP. Because DMPA reportedly impairs glucoregulatory function in humans and rhesus macaques, as well as predisposes humans to diabetes mellitus (DM), we performed a retrospective study to further investigate its potential long-term clinical effects in animals with and without DM. Using a cohort of 29 rhesus macaques, we explored the hypotheses that DMPA treatment accelerates the onset of DM and that its use in rhesus macaques with endometriosis worsens clinical outcome measures (lifespan, body weight and body condition score). For both body weight and body condition score, a declining and statistically significant trend in mean values was evident as macaques developed either DM, or endometriosis or both. The addition of DMPA did not significantly alter this pattern. The presence of DM, endometriosis, or DMPA treatment statistically but not clinically significantly increased risk of death. Similarly, the presence of the 2 highly correlated variables endometriosis and DMPA treatment statistically but not clinically significantly increased the risk of incident DM. These results indicate that DMPA treatment was associated with worsening trends in lifespan and incident DM, however these trends did not achieve clinical significance in this cohort.
