Dysmenorrhea in adolescents requires careful investigation of endometriosis-an analysis of early menstrual experiences in a large case-control study.

Introduction: Recent evidence shows that endometriosis, a significant cause of infertility, may already present in adolescents. Dysmenorrhea, often leading to school absences, is a key symptom of the maturing menstrual cycle but also of endometriosis. However, it is often perceived as "normal" and left untreated. In adolescents, laparoscopy, the standard procedure to diagnose endometriosis, is performed particularly cautiously. To improve reproductive health in adolescents, we evaluate associations between early menstrual experiences and endometriosis. Methods: Retrospective data on early menstrual experiences from 563 women with surgically/histologically verified endometriosis and from 563 age-matched controls were compared. Study participants were recruited in Switzerland, Germany, and Austria. Information on menstrual experiences was collected via a structured questionnaire. Results: The bivariate analysis showed that early menarche (p = 0.004), dysmenorrhea and negative memories of menarche (p < 0.001) were significantly associated with a diagnosis of endometriosis. After controlling for confounders in bivariate regression analysis occurrence of dysmenorrhea (p = <0.001, OR 5,74, 95% CI 3.82-7.22) especially with onset >3 years after menarche ((p = <0.001, OR 3.42, 95% CI 2.09-5.64) remained statistically significant predictors for diagnosis of endometriosis. Dysmenorrhea in mothers and mothers' perceived attitude towards menstruation were not associated with the occurrence of Endometriosis. Conclusions: Dysmenorrhea and onset of dysmenorrhea at menarche or several years after it are strongly associated with the development of endometriosis. As mothers perceived attitudes towards menstruation show no significant association with their daughters' experiences, physical symptoms accompanying menarche and menstrual period pain in adolescents seem to be very reliable predictors in diagnosis of endometriosis. Therefore, dysmenorrhea in adolescents requires careful investigation of possible endometriosis, especially if it does not respond to medical management. Clinical trials registration: The study was registered on ClinicalTrials.gov, identifier (NCT02511626).

Physical Activity in Women with Endometriosis: Less or More Compared with a Healthy Control?

BACKGROUND: Endometriosis, i.e., endometrial-like tissue outside the uterus, is a chronic inflammatory condition affecting physical functioning. However, the specific levels of physical activity (PA) in the context of endometriosis and different disease symptoms remain unclear. METHODS: This multi-center, cross-sectional study compared PA levels and influencing factors in endometriosis patients and non-endometriosis patients. Data were collected through questionnaires. Endometriosis was surgically confirmed. A statistical analysis was performed with appropriate tests. RESULTS: The study included 460 women with endometriosis and 460 age-matched women without this condition. The two groups did not differ significantly in terms of age, education level, or stable partnership. Women with endometriosis exhibited lower PA levels, practicing fewer hours of sports weekly and climbing fewer stairs daily compared to the control group. These differences remained significant after controlling for confounding factors. Factors such as endometriosis, current dysmenorrhea, and depression were associated with decreased PA. CONCLUSIONS: These findings suggest that women with endometriosis engage in less PA compared to those without this condition. These results highlight the need for interventions to promote increased PA in endometriosis patients and harness the associated health benefits. Further research is warranted to explore the underlying mechanisms and develop tailored exercise therapies for this population.

Did the first wave of the COVID-19 pandemic impact the cesarean delivery rate? A retrospective cohort study at a primary care center in Switzerland.

OBJECTIVES: During the first 3 months of the coronavirus disease 2019 (COVID-19) pandemic, our hospital's quality management team determined a decline in the rate of cesarean deliveries (CD). Thus, in this study we examined both the factors associated with this decrease as well as neonatal outcomes. METHODS: This was a retrospective observational cohort study comparing deliveries (n=597) between March and May 2020 (first nationwide "lockdown" in Switzerland) with those during the same period in 2018 and 2019 (n=1,063). A multivariable logistic regression analysis was used to examine the association between CD and the pandemic, adjusting for relevant risk factors for CD. RESULTS: The overall rate of CD during the pandemic period was lower (30.0%), than during the pre-pandemic period (38.7%, unadjusted odds ratio 0.68, 95% confidence interval [95%CI]: 0.55 to 0.84, p=0.0004) a result that was supported by the adjusted odds ratio (0.73, 95%CI: 0.54 to 0.99, p=0.04). CONCLUSIONS: The results of this study confirmed a significant reduction in the rate of CD in early 2020, during the first lockdown period due to COVID-19, but without major differences in maternal and infant health indicators or in obstetric risk factors than before the pandemic. These results may have been due to a difference in the composition of the obstetric team as well as the behavior of the obstetrics team and in the patients during the pandemic, given the burden it placed on healthcare systems. However, this hypothesis remains to be tested in further research.

Sexual Satisfaction and Frequency of Orgasm in Women With Chronic Pelvic Pain due to Endometriosis.

BACKGROUND: Dyspareunia, one of the main symptoms of the chronic gynecological pelvic pain disorder endometriosis, may interfere with the likelihood of reaching an orgasm, yet for women with dyspareunia, no data on orgasm rates in different sexual activities are available. AIM: The aim of this study was to evaluate the ability to reach an orgasm and its association with sexual satisfaction during different sexual activities in women with a chronic pelvic pain disorder and in healthy control women. METHODS: A set of questionnaires including the brief index of sexual functioning and global sexual functioning was used to evaluate sexuality in women affected with endometriosis (n = 434) and a nonaffected control group (n = 434) recruited in German-speaking countries. OUTCOMES: The primary outcome measure of this study was the orgasm rate during different types of sexual activities. RESULTS: Only the ability to have an orgasm during sexual intercourse (P = .002) but not during masturbation (P = .509) or partnered noncoital sexual activities (P = .229) is affected by endometriosis. Dyspareunia was associated with a reduced ability to experience an orgasm during intercourse for endometriosis patients (P = .020) and control women (P = .006). The ability to orgasm during noncoital sexual activities (P = .006) and sexual intercourse (P = .038) was associated with a higher sexual satisfaction in women with endometriosis. For controls, only the ability to achieve an orgasm with sexual intercourse was associated with sexual satisfaction (P = .038). CLINICAL IMPLICATIONS: Sexual counselling as part of medical support could help couples living with chronic pelvic pain of the female partner integrate noncoital sexual activities in their sex lives, leading to fewer sex-related problems and higher sexual desire and satisfaction. STRENGTHS AND LIMITATIONS: This study is the first to examine different ways of achieving an orgasm and sexual satisfaction in a large group of women with endometriosis and a matched control group. The breadth of the questionnaire allowed a differentiated analysis of factors influencing the likelihood of achieving an orgasm and overall sexual satisfaction. The one limitation is that the length and the intimate nature of the questionnaire possibly resulted in reluctance to answer this part of the questionnaire. CONCLUSION: Partnered noncoital sexual activities may represent an alternative to reach orgasm for women with endometriosis-related chronic pelvic pain or anorgasmia during sexual intercourse.

Qualitative and quantitative aspects of sex life in the context of endometriosis: a multicentre case control study.

RESEARCH QUESTION: What are the specific characteristics of sexual activity in women with endometriosis compared with women without endometriosis? DESIGN: Multicentre case control study. Participants were recruited from university hospitals, district hospitals and doctor's offices in Germany, Switzerland and Austria. A total of 565 women with endometriosis were pair-matched to 565 control women by age and ethnic background. Diagnosis of endometriosis was confirmed by histology, and disease stage was classified according to American Society for Reproductive Medicine criteria. Data on sexuality were collected using selected questions from the Brief Index of Sexual Function and the Sexual History Form. RESULTS: Altogether, 69.1% of women with endometriosis and 77.8% of control women engaged in sexual activity during the month before the study period (P < 0.001). Overall, 42.3% of endometriosis-affected women and 30.5% of the control women desired a higher frequency of sexual activity (P < 0.001). Petting, foreplay and vaginal sexual intercourse were reported to be practised less often by women with endometriosis. Frequencies for masturbation, reciprocal masturbation, oral and anal sex were similar in both groups. Dyspareunia was negatively associated with sexual activity (OR 2.42, 95% CI 1.26 to 4.63), whereas chronic pain showed no association with sexual activity (OR 1.35, 95% CI 0.93, 1.96). CONCLUSIONS: Women with endometriosis have lower frequencies of petting, foreplay and vaginal sexual intercourse than control women; this difference has to be attributed, at least in part, to dyspareunia. Potentially pain-free sexual options are used to a limited degree. As endometriosis-affected women desire higher levels of sexual activity, sexual counselling should be included in medical support.

Does endometriosis affect professional life? A matched case-control study in Switzerland, Germany and Austria.

OBJECTIVES: Endometriosis is a gynaecological disease most commonly causing severe and chronic pelvic pain as well as an impaired quality of life. The aim of this study was to investigate if and how endometriosis affects choices regarding professional life as well as the quality of daily working life. DESIGN, SETTING AND PARTICIPANTS: In the context of a multicentre case-control study, we collected data from 505 women with surgically/histologically confirmed diagnosis of endometriosis and 505 matched controls. Study participants were recruited prospectively in hospitals and doctors' practices in Switzerland, Germany and Austria. Using a detailed questionnaire, the study investigated work-life and career choices of study participants. MAIN OUTCOME MEASURES: Associations between endometriosis/disease symptoms and limitations in career development as well as ability to work. RESULTS: Women with endometriosis were less often able to work in their desired profession than women from the control group (adjusted OR=1.84, 95% CI: 1.15 to 2.94, R2=0.029, p=0.001) and they had to take health-related limitations into consideration in their career decisions to a significantly higher degree than women in the control group (OR=4.79, 95% CI: 2.30 to 9.96, R2=0.063, p<0.001). Among women with endometriosis, chronic pain was significantly associated with increased sick leave (OR=3.52, 95% CI: 2.02 to 6.13, R2=0.072, p<0.001) as well as with loss of productivity at work (OR=3.08, 95% CI: 2.11 to 4.50, R2=0.087, p<0.001). CONCLUSIONS: Endometriosis is associated with impairment of professional life, in particular with regard to career choices. Further research to develop strategies to support endometriosis-affected women in realising professional opportunities is recommended. TRIAL REGISTRATION NUMBER: NCT02511626; Pre-results.

The use of home remedies and complementary health approaches in endometriosis.

RESEARCH QUESTION: Conventional treatments are often associated with adverse effects and endometriosis pain symptoms may reoccur despite treatment. Consequently, many women use complementary health approaches (CHA) and home remedies (HR) to relieve their pain. The aim of this study was to examine the frequency and the subjectively perceived efficacy of CHA/HR use by women affected by endometriosis. DESIGN: Retrospective evaluation using medical charts and a questionnaire. Women recruited in hospitals and in self-help groups were asked about the use of 'topical heat', 'repose/relaxation', 'movement/massages', 'homeopathy/phytotherapy', 'acupuncture/traditional Chinese medicine (TCM)' and 'kinesiology/physiotherapy'. RESULTS: From a total of 574 women with a confirmed diagnosis of endometriosis, 359 (62.5%) applied some form of CHA/HR. Women suffering from fatiguing disease symptoms more often selected alternative therapies (odds ratio [OR] 3.14, 95% confidence interval [CI] 1.39-7.11, P = 0.006) compared with women without these characteristics. Furthermore, women dissatisfied with healthcare provided by their treating physician, more frequently (OR 2.30, 95% CI 1.19-4.45, P = 0.013) chose the aforementioned alternative strategies. CONCLUSION: As conventional therapies may not be sufficiently effective, women's needs should be closely examined, and individual treatment options should be discussed and initiated by clinicians to provide the best comprehensive treatment possible for endometriosis.

Satisfaction with medical support in women with endometriosis.

Endometriosis affects various aspects of women's lives. We searched for predictors for patient satisfaction with medical support (PSwMS) in women with endometriosis. The study was designed as a multi-centre retrospective cohort study. We approached women with histologically confirmed endometriosis from 2010 until 2016, comparing women satisfied to women dissatisfied with medical support. We analysed data on characteristics of endometriosis, PSwMS and the influence of disease characteristics on PSwMS. Information on satisfaction with medical support was collected through a standardized questionnaire. After exclusion of 73 women because of inchoately filled in questionnaires, data from 498 women was evaluated. Altogether, it was observed that 54.6% (n = 272) of the study participants were satisfied with medical support and 45.4% (n = 226) were not. Feeling adequately informed by the time of diagnosis (p < 0.001), taking women's mental troubles seriously (p < 0.001) and supporting women in handling their pain (p < 0.001) were significantly associated with satisfaction. We found adequate information to be the most distinctive indicator for PSwMS. Further, acknowledging psychological distress and supporting women in handling their symptoms rather than to alleviate them, positively affect PSwMS. To achieve PSwMS, healthcare providers have to give adequate information on endometriosis and its management.

Fatigue - a symptom in endometriosis.

STUDY QUESTION: Is fatigue a frequent symptom of endometriosis? SUMMARY ANSWER: Fatigue is an underestimated symptom of endometriosis as it affects the majority of women with endometriosis, but it is not widely discussed in literature. WHAT IS KNOWN ALREADY: Fatigue can be a symptom of endometriosis causing major distress impacting the daily activities and quality of life of women with endometriosis. However, few studies with large sample sizes have investigated fatigue as a symptom of endometriosis. STUDY DESIGN, SIZE, DURATION: The study was designed as a multi-center matched case-control study. Recruitment took place at hospitals and private practices in Switzerland, Germany and Austria between 2010 and 2016. Data was collected from 1120 women, 560 of them with endometriosis. The women with endometriosis were matched to 560 control women in regard to age ±3 years and ethnic background. PARTICIPANTS/MATERIALS, SETTING, METHODS: Diagnosis of women with endometriosis had to be surgically and histologically confirmed. Surgical exclusion or absence of any endometriosis-identifying symptoms was required for control subjects. Materials included surgical and histological reports as well as data retrieved from a self-administered questionnaire. This study focused on the symptom fatigue in endometriosis. Relationships of variables were established by regression analysis and associations were quantified as odds ratios. MAIN RESULTS AND THE ROLE OF CHANCE: Frequent fatigue was experienced by a majority of women diagnosed with endometriosis (50.7% versus 22.4% in control women, P < 0.001). Fatigue in endometriosis was associated with insomnia (OR: 7.31, CI: 4.62-11.56, P < 0.001), depression (OR: 4.45, CI: 2.76-7.19, P < 0.001), pain (OR: 2.22, CI: 1.52-3.23, P < 0.001), and occupational stress (OR: 1.45, CI: 1.02-2.07, P = 0.037), but was independent of age, time since first diagnosis and stage of the disease. LIMITATIONS, REASONS FOR CAUTION: Women with asymptomatic endometriosis cannot be excluded in the control group which would lead to underestimation of our results. The study's design allows no evaluation of causal effects. WIDER IMPLICATIONS OF THE FINDINGS: As fatigue is experienced by numerous women with endometriosis, it needs to be addressed in the discussion of management and treatment of the disease. In addition to treating endometriosis, it would be beneficial to reduce insomnia, depression, pain and occupational stress in order to better manage fatigue. STUDY FUNDING/COMPETING INTEREST(S): There was no additional funding received for this study and no conflict of interest. TRIAL REGISTRATION NUMBER: ClinicalTrials.gov, NCT02511626.

Temporal trends of postpartum haemorrhage in Switzerland: a 22-year retrospective population-based cohort study.

AIM: Postpartum haemorrhage (PPH) is one of the leading causes of maternal morbidity and mortality. Studies have reported an increase in incidence of postpartum haemorrhage in recent years. Our goal was to investigate changes in the incidence of postpartum haemorrhage (PPH) and its risk factors in Switzerland from 1993 to 2014. METHODS: This population-based retrospective cohort study used data from the national Swiss Hospital in-patient database for obstetric and gynaecological hospital admissions - "Arbeitsgemeinschaft Schweizer Frauenkliniken" (ASF Statistik). All patients with deliveries between January 1993 and December 2014 were included. We used the database codes to identify patients with PPH, maternal factors, pregnancy-related and delivery-related factors. Significant changes in temporal trends were determined using Mantel-Haenszel test for trend. Multivariable logistic regression analyses were conducted to assess PPH and risk factors. RESULTS: Births complicated by PPH in Switzerland increased from 2.5% in 1993 to 4.5% in 2014 (p <0.001), paralleled by an increase in uterine atony. Failure to progress during the second stage of labour (odds ratio [OR] 1.5, 95% confidence interval [CI] 1.5-1.6), oxytocin augmentation (OR 1.2, 95% CI 1.2-1.3), vacuum extraction (OR 1.1, 95% CI 1.1-1.2), and especially abnormally invasive placenta (OR 10.4, 95% CI 9.5-11.5) and placenta praevia (OR 4.9, 95% CI 432-5.6) were factors with the highest risk for postpartum haemorrhage. CONCLUSIONS: Postpartum haemorrhage is a relatively common and potentially dangerous obstetric complication with increasing incidence over the last two decades in Switzerland. Its increase over time has been paralleled by an increase in uterine atony.

Endometriosis, especially mild disease: a risk factor for miscarriages.

OBJECTIVE: To investigate the prevalence of miscarriage in women with endometriosis (WwE) compared with disease-free control women (CW). DESIGN: Cross-sectional analysis nested in a retrospective observational study (n = 940). SETTING: Hospitals and associated private practices. PATIENT(S): Previously pregnant women (n = 268) within reproductive age in matched pairs. INTERVENTION(S): Retrospective analysis of surgical reports and self-administered questionnaires. MAIN OUTCOME MEASURE(S): Rate of miscarriage, subanalysis for fertility status (≤12 vs. >12 months' time to conception), endometriosis stages (revised American Society of Reproductive Medicine classification [rASRM] I/II vs. III/IV) and phenotypic localizations (superficial peritoneal, ovarian, and deep infiltrating endometriosis). RESULT(S): The miscarriage rate was higher in WwE (35.8% [95% confidence interval 29.6%-42.0%]) compared with CW (22.0% [16.7%-27.0%]); adjusted incidence risk ratio of 1.97 (95% CI 1.41-2.75). This remained significant in subfertile WwE (50.0% [40.7%-59.4%]) vs. CW (25.8% [8.5%-41.2%]) but not in fertile WwE (24.5% [16.3%-31.6%]) vs. CW (21.5% [15.9%-26.8%]). The miscarriage rate was higher in women with milder forms (rASRM I/II 42.1% [32.6%-51.4%] vs. rASRM III/IV 30.8% [22.6%-38.7%], compared with 22.0% [16.7%-27.0%] in CW), and in women with superficial peritoneal endometriosis (42.0% [32.0%-53.9%]) compared with ovarian endometriosis (28.6% [17.7%-38.7%]) and deep infiltrating endometriosis (33.9% [21.2%-46.0%]) compared with CW (22.0% [16.7%-27.0%]). CONCLUSION(S): Mild endometriosis, as in superficial lesions, is related to a great extent of inflammatory disorder, possibly leading to defective folliculogenesis, fertilization, and/or implantation, presenting as increased risk of miscarriage. CLINICAL TRIAL REGISTRATION NUMBER: NCT02511626.

The value of endocervical curettage after conization for cervical intraepithelial neoplasia.

The objective of this study is to assess the value of postcone endocervical curettage, after conization of cervical intraepithelial neoplasia or carcinoma as a predictive tool for residual lesions. This is a retrospective observational study. All data were obtained by the University Hospital of Zurich, Department of Gynaecology. One hundred fifty patients underwent hysterectomy within 12 months after conization and endocervical curettage from 1993 to 2006. To analyze the sensitivity, specificity, and the positive predictive value (PPV) and negative predictive value (NPV) of the endocervical curettage after conization, we used the Fisher exact test and χ(2) test. The main outcome measures are the sensitivity and specificity as well as the PPV and NPV of the postconization endocervical curettage. The endocervical curettage exhibited a sensitivity of 0.38, a specificity of 0.85, a PPV of 0.56, and an NPV of 0.73. Comparing patients younger than 50 years to women 50 years or older, endocervical curettage had a sensitivity of 0.35 and 0.44, a specificity of 0.83 and 0.94, a PPV of 0.46 and 0.88, and an NPV of 0.76 and 0.63, respectively. The endocervical curettage after conization of cervical intraepithelial neoplasia does not generally improve the prediction of residual lesions. However, in women 50 years or older, a higher specificity and PPV, 0.94 and 0.88, respectively, was observed. Therefore, this subgroup of patients may benefit from an endocervical curettage.
