RESUMEN

PURPOSE: To study trends regarding the use of contraceptive methods and digital health modalities and to identify target groups of natural family planning (NFP). MATERIAL AND METHODS: Using an online questionnaire specifically developed for this study in German (utilizing the online tool at 'www.surveymonkey.com'), we analysed the attitude towards NFP -methods and -apps, the need for contraceptive effectiveness in general, the perceived contraceptive effectiveness of NFP methods, and differences between NFP users and non-NFP users among 779 sexually active German-speaking women of fertile age (18-50 years) from November 2019 to October 2020. RESULTS AND CONCLUSIONS: Participants used NFP more frequently than they did five years ago. Women aged 30 years and older, with higher levels of education, who are living with a partner and have children, seem to be the target group for NFP methods. Concerning the wish for contraceptive effectiveness we found significant (p < .001) differences between NFP and non-NFP users. Furthermore, an increasing number of women wants to use NFP-methods and -apps for contraception; thus, non-hormonal contraceptive options should be offered. The majority of current NFP users stated that the handling and effectiveness of NFP have been improved by digitalisation.

RESUMEN

Extracardiac rhabdomyomas are rare benign tumors. According to histopathologic and clinical characteristics, they are divided into 3 subgroups: adult, fetal, and genital rhabdomyomas. Various adult extracardiac rhabdomyomas have been reported in the head and neck region, whereas genital rhabdomyomas are uncommon. Here, we report on a uterine genital rhabdomyoma in a 32-yr-old woman with secondary sterility. After myomectomy, the histopathologic analysis showed a slow cycling tumor with striated muscle differentiation and without any evidence of malignancy. Immunohistochemical staining proved coexpression of actin, caldesmon, and desmin. To the best of our knowledge, this is the first case of a uterine-based genital rhabdomyoma.

RESUMEN

PURPOSE: Obstetric anal sphincter injuries (OASIS) increase the risk for pelvic floor dysfunctions. The goal of this study was to examine the long-term outcomes after OASIS on pelvic floor functions and quality of life. MATERIAL AND METHODS: Between 2005 and 2013, 424 women had an OASIS at the Women University Hospital Ulm. Out of these 71 women completed the German pelvic floor questionnaire, which includes questions regarding prolapse symptoms as well as bladder, bowel and sexual function. In addition, 64 women were physically examined, including a speculum examination to evaluate the degree of prolapse, a cough test to evaluate urinary stress incontinence (SI) and an evaluation of both pelvic floor sphincter (modified Oxford score) and anal sphincter contraction. RESULTS: A high rate of pelvic floor disorders after OASIS was found, as 74.6% of women reported SI, 64.8% flatus incontinence and 18.3% stool incontinence, respectively. However, only few women stated a substantial negative impact on quality of life. The clinical examination showed that a positive cough test, a weak anal sphincter tone and a diagnosed prolapse correlated with the results of the self-reported questionnaire. CONCLUSION: On one hand, OASIS has an influence on pelvic floor function going along with lots of complaints, while on the other hand, it still seems to be a taboo topic, as none of the participants spoke about the complaints after OASIS with a doctor. Therefore, the gynecologist should actively address these issues and offer therapy options for the women with persisting problems.

RESUMEN

BACKGROUND: First manifestation of Cushing's syndrome during pregnancy is rare. The diagnosis of both Cushing's and primary aldosteronism within a pregnancy has not been previously documented. Diagnosis is especially challenging due to the normal physiological changes that occur during pregnancy. Consequently, many tests that are normally used for diagnosis are not reliable. Tumor based etiologies can be surgically removed. Etiologies that are not tumor based are challenging to treat during pregnancy. CASE PRESENTATION: A 25 year old G1P0 was admitted in the 22 5/7 week of pregnancy with elevated blood pressure (200/100 mm Hg), acne, moon facies, abdominal striae and hirsutism. With five antihypertensive medications her blood pressure remained 190/100 mm Hg. The patient was admitted to the ICU for intravenous medications and monitoring. She was diagnosed with Cushing's syndrome and primary aldosteronism. In spite of therapy with spironolactone and metyrapone she developed preeclampsia and was delivered in the 26 0/7 week of pregnancy. At her follow up visit eight weeks postpartum she had blood pressure within normal limits, no clinical signs or symptoms, and all medications had been discontinued. CONCLUSIONS: Early diagnosis of pregnancy induced Cushing's syndrome and primary aldosteronism requires an interdisciplinary approach. Late detection has been associated with increased perinatal morbidity and mortality including but not limited to placental abruption and intrauterine demise. Collaboration is essential in the optimization of maternal and fetal outcomes.

RESUMEN

For several years there is an evidence for a relationship between the polycystic ovary syndrome (PCOS) and of insulin resistance; therefore metformin, an insulin sensitizer, is used for the treatment for more than 10 years. However, the evidence for metformin is assessed controversially. This review will give an overview about the data published on this topic.

RESUMEN

OBJECTIVE: Obesity is an important issue among fertile women as it may affect obstetric and neonatal outcomes. METHODS: Obstetric and neonatal outcomes of primiparous women were retrospectively analyzed in non-obese (n=11387) and obese (n=943) women. A subgroup analysis was performed in obese women divided into three groups: Grade I obesity (Group A, n=654), Grade II obesity (Group B, n=192), and Grade III obesity (Group C, n=97). Odds ratios (OR) were expressed with the corresponding 95% confidence intervals (CI). RESULTS: The incidence of gestational diabetes (non-obese, 1.9%; obese, 7.6%; Group C, 19.6%) and preeclampsia (non-obese, 3.3%; obese, 13.5%; Group C, 17.5%) increased with rising weight. The risk of non-elective cesarean section was significantly higher in obese women than in non-obese women (21.7% vs. 13.2%). The risk of extreme preterm birth (before 28 weeks of gestation) doubled in the Grade I obesity group (OR, 2.1; 95% CI, 1.4-3.2) and nearly tripled in women with body mass index ≥35 kg/m2 (OR, 2.9; 95% CI, 1.7-4.9). CONCLUSION: Pre-pregnancy obesity is associated with higher incidences of gestational diabetes and preeclampsia. Our study shows that obese women have a higher risk of non-elective cesarean section and preterm birth.

RESUMEN

OBJECTIVES: Because of substantial toxicities in older adults, chemotherapy is often omitted while the frequency of radiotherapy changes only minimally. In this study, we addressed the value of different assessments for predicting fatigue after radiotherapy in older breast cancer patients. PATIENTS AND METHODS: We included 74 women with primary breast cancer over the age of 65 years treated with radiotherapy (26 % with additional chemotherapy). Assessments were conducted before adjuvant treatment and after radiotherapy. The assessments included the Vulnerable Elders Survey (VES-13), the Karnofsky Performance Status (KPS), the EORTC Quality of Life assessment (EORTC-QLQ-C30), a cancer-specific comprehensive geriatric assessment (cancer-specific CGA), and the Fried frailty score. Multiple linear regression analyses were used to assess correlations with the FACIT-fatigue scale. RESULTS: Patients were on average 71 years old (range, 65-86 years). Most tumors (n=62) were classified as intermediate risk according to the St. Gallen consensus. The cancer-specific CGA was best associated with fatigue (p < 0.001, ß estimate = 1.75), followed by the Fried frailty score (for the score of 1 versus reference of 2 and higher: p = 0.035, ß estimate = - 5.74). There were no significant ceiling effects but there were substantial floor effects for the VES-13, KPS, and frailty score. CONCLUSION: The cancer-specific CGA and the Fried frailty score (driven mainly by the item "exhaustion") outperformed the other indices in predicting fatigue in a group of rather well-functioning older women with primary breast cancer.

RESUMEN

PURPOSE: Work-life balance is an upcoming issue for physicians. The working group "Family and Career" of the German Society for Gynecology and Obstetrics (DGGG) designed a survey to reflect the present work-life balance of female and male gynecologists in Germany. METHODS: The 74-item, web-based survey "Profession-Family-Career" was sent to all members of the DGGG (n = 4,564). In total, there were 1,036 replies (23%) from 75% female gynecologists (n = 775) aged 38 ± 7 (mean ± standard deviation [SD]) years and 25% male (n = 261) gynecologists aged 48 ± 11 years. Statistical analyses were performed using the mean and SD for descriptive analysis. Regression models were performed considering an effect of p ≤ 0.05 as statistically significant. RESULTS: 47% women and 46% men reported satisfaction with their current work-life balance independent of gender (p(gender) = 0.15). 70% women and 75 % men answered that work life and private life were equally important to them (p(gender) = 0.12). While 39% women versus 11% men worked part-time (p gender < 0.0001), men reported more overtime work than women (p(gender) < 0.0001). 75 % physicians were not satisfied with their salary independent of gender (p(gender) = 0.057). Work life affected private life of men and women in a similar way (all p(gender) > 0.05). At least 37% women and men neglected both their partner and their children very often due to their work. CONCLUSIONS: Female physicians often described their work situation similar to male physicians, although important differences regarding total work time, overtime work and appreciation by supervisors were reported. Work life affected private life of women and men in a similar way.

RESUMEN

OBJECTIVE: Endometriosis affects approximately 10% of women of reproductive age and leads to significant morbidity and financial burden. Consequently, countries such as France and Germany are formulating strategies to combat endometriosis. In this study, we propose the implementation of our three-dimensional model (3D-E) to raise awareness about endometriosis and enhance timely diagnosis, treatment, and long-term care for affected patients. METHODS: Based on the adapted Six Sigma Principle and the modified recommendation of Sales et al. for implementing evidence-based findings into a clinical routine, we first conducted a comprehensive investigation to identify risk factors leading to diagnostic delay of endometriosis. After identifying improvable factors, the applicable options were selected due to defined criteria such as integrability in the clinical routine, cost-effectiveness, and evidence-based-principle. Finally, solutions feasible for health care providers were integrated and the 3D-E model was established. RESULTS: Some of the main risk factors contributing to diagnostic delays are symptoms acceptance and misinterpreted symptoms, especially if presenting to nongynecologists in cases of extragenital endometriosis with atypical presentation. Therefore, we tried to sensitize colleagues (first dimension) with a review paper in Germany's largest medical journal and started an elective for medical students (second dimension) at our university. In order to involve additional health care professionals in endometriosis care (third dimension), we are preparing the concept of the EndoNurse. CONCLUSION: The 3D-E model is a relatively low-cost, comprehensive, and worldwide adaptable approach for facilitating knowledge transfer, sensitizing health care providers, and improving endometriosis diagnostics and therapy for patients with endometriosis who are in the center of the model.

RESUMEN

Background: There are many reports about variations in the menstrual cycle after infection with SARS-CoV-2 or vaccination against it. However, data on SARS-CoV-2 infection or vaccination-related changes in menstruation-associated endometriosis-typical symptoms such as dysmenorrhea, dyspareunia, dyschezia, dysuria, and bloating are rare or missing. Methods: This retrospective study was performed as an online survey among employees and students at the University Hospital Ulm, Germany. Changes regarding the presence of mentioned symptoms and after immunization (vaccination and/or infection) were evaluated with the McNemar Test. Additionally, the risk factors associated with these changes and associations between a subjectively perceived general change in menstruation and changes in the symptoms were evaluated. Results: A total of 1589 respondents were included in the final analysis. Less than 4% of respondents reported the occurrence of new symptoms that they had not experienced before immunization. Overall, there was a significant reduction in the presence of dysmenorrhea, back pain, dyschezia, bloating, and dyspareunia after immunization against coronavirus (p < 0.001). Only 2.3% of all participants reported to have been diagnosed with endometriosis. Factors associated with changes in endometriosis-typical symptoms following immunization were body mass index, age, endometriosis, and thyroid disease. Conclusions: Our results provide unique data about a reduction in the incidence of endometriosis-associated symptoms as dysmenorrhea, dyschezia, and dyspareunia after immunization against COVID-19.

RESUMEN

Polycystic ovary syndrome (PCOS) is diagnosed according to the Rotterdam criteria, where two of the following three criteria must be met: Anovulation, hyperandrogenism, and characteristic morphology by sonography. Women diagnosed with PCOS are at higher risk for diabetes and impaired glucose tolerance. Therefore, these women should be carefully counselled about lifestyle measures and improvements in fertility and pregnancy outcomes. Some women benefit from metformin, which needs to be clarified by off-label use. For fertility, mild stimulation is possible in women with unovulatory cycles, whereas women with PCOS need to be monitored more closely for the development of gestational diabetes, preeclampsia or hypertension during pregnancy.

RESUMEN

OBJECTIVE: Abnormalities of the menstrual cycle were reported after infection with SARS-CoV-2 and vaccination against it, but the available data are very heterogeneous, do not reflect intermenstrual variations or regional differences, and their risk factors are missing. METHODS: We performed a survey-based study among 6383 employees and students of Ulm University Hospital in Germany between March 1 and 31, 2021. Attributes of menstrual cycles such as cycle length (CL), menses duration (MD), and bleeding volume (BV) were reported as categorical variables before and after immunization against SARS-CoV-2 (first, second, third vaccination or infection). Additionally, the potential risk factors for cycle changes were evaluated and all participants reported the subjective perception of changes, their duration, and time of occurrence. RESULTS: The final analysis included 1726 participants. CL and BV significantly changed after vaccination, but not MD. The subjective perception showed only slight levels of agreement with the objective changes, with the highest Cohen's kappa for CL. The risk factors for the variations in CL were previous cycle irregularities, and risk factors for the changes in BV were age and body mass index. The combination of vaccines (homogenous or heterogeneous) and different types of immunization (infection and vaccination) had no significant effect on cycle irregularities. CONCLUSION: In summary, immunization against SARS-CoV-2 causes changes in the characteristics of the menstrual cycle, which are mostly temporary. The individual risk factors, but not the type of immunization, can affect the mentioned changes.

RESUMEN

Purpose The aim of this guideline is to standardize the diagnosis and therapy of recurrent miscarriage (RM) using evidence from the recent literature. This is done by using consistent definitions, objective evaluations and standardized treatment protocols. Methods When this guideline was compiled, special consideration was given to previous recommendations in prior versions of this guideline and the recommendations of the European Society of Human Reproduction and Embryology, the Royal College of Obstetricians and Gynecologists, the American College of Obstetricians and Gynecologists and the American Society for Reproductive Medicine, and a detailed individual search of the literature about the different topics was carried out. Recommendations Recommendations about the diagnostic and therapeutic procedures offered to couples with RM were developed based on the international literature. Special attention was paid to known risk factors such as chromosomal, anatomical, endocrinological, physiological coagulation, psychological, infectious and immune disorders. Recommendations were also developed for those cases where investigations are unable to find any abnormality (idiopathic RM).

RESUMEN

PURPOSE: To evaluate the outcome of frozen-thawed embryo transfer (FET) when freezing takes place at the pronuclear stage, a retrospective analysis was performed comparing spontaneous and artificial cycles. METHODS: 148 women received FET in a spontaneous cycle (Group A) and 55 women received FET in an artificial cycle (Group B) induced by administering estrogen (E2) and progesterone (P). Pregnancy rates, endometrial thickness and serum levels of E2, P and luteinizing hormone (LH) were measured. Statistical analysis included the mean, the standard deviation, the Chi-squared test and the T-test. RESULTS: The clinical pregnancy rate was 34.5% for Group A and 21.8% for Group B (p = 0.084), with a live birth rate of 20.9% and 12.7% respectively (p = 0.15). There was no difference in endometrial thickness or the P levels, while LH and E2 levels were significantly higher in group B (p < 0.0001). CONCLUSION: Our retrospective study shows a trend towards higher pregnancy rates and live birth rates with the administration of FET during a spontaneous cycle compared to FET during an artificial cycle. Large randomized controlled trials are needed to confirm this trend.

RESUMEN

OBJECTIVE: To investigate the advantages of cryopreserved medulla-containing ovarian cortex grafts with those of commonly used sole cortex grafts for fertility preservation by analyzing tissue quality, neovascularization processes, and the number of vital follicles. DESIGN: Experimental setting of cryopreserved bovine ovarian cortex tissue grafts with or without medulla tissue. SETTING: Laboratory animal research at Ulm University, Ulm, Germany. ANIMALS: Bovine ovaries and fertilized chicken eggs. INTERVENTION(S): Experimental setting of bovine ovarian tissue samples grafted on the chicken chorioallantoic membrane (CAM) after cryopreservation and thawing to examine histologic tissue integrity, apoptosis and proliferation immunohistochemically, blood vessel counts and determine the presence of neutral red-stained vital follicles. MAIN OUTCOME MEASURE(S): We used hematoxylin and eosin staining to visualize tissue structures, immunohistochemistry with anti-caspase 3 to detect apoptosis, anti-Ki67 to examine proliferation, blood vessel count on the chicken CAM to investigate neovascularization processes, and neutral red staining to evaluate vital follicles. RESULT(S): We demonstrated that in all analyzed tissue samples, after cryopreservation, thawing, and grafting on the chicken CAM, there was excellent tissue integrity and quality, as shown by extremely rare apoptosis processes analyzed using immunohistochemical caspase 3 staining (sole cortex, 0.54%; thin medulla-containing cortex, 0.43%; thick medulla-containing cortex, 0.13%; and sole medulla, 2.82%). Moreover, we detected increased neovascularization in the vicinity of medulla and medulla-containing grafts (small blood vessels: cortex 8.7, thin medulla-containing cortex 9.9, thick medulla-containing cortex 9.7, and medulla 9.8; very small blood vessels: cortex 7.0, thin medulla-containing cortex 13.0, thick medulla-containing cortex 12.0, and medulla 15.0), with higher Ki67-detected proliferation (cortex, 17.58%; thin medulla-containing cortex, 20.28%; thick medulla-containing cortex, 20.56%; and medulla, 29.9%). Additionally, we identified an increased number of vital follicles in medulla-containing cortex grafts compared with the number of vital follicles in sole cortex tissue (cortex, 256.1; thin medulla-containing cortex, 338.2; thick medulla-containing cortex, 346.6; and medulla, 8.1). CONCLUSION(S): In this experimental setting, bovine medulla-containing cortex tissue had excellent tissue structure and quality after cryopreservation and thawing and increased neovascularization and an augmented vital follicle count after grafting than the commonly used sole cortex tissue. Therefore, we suggest reconsidering the current cryopreservation and grafting processes in humans for fertility preservation by favoring retain medulla tissue at the ovarian cortex.

RESUMEN

The in-vitro culture of human embryos in a medium subjected to regular short intervals of mechanical agitation leads to increased development rates. This type of treatment tries to mimic conditions in nature whereby oviductal fluid is mechanically agitated by the epithelial cilia. This phenomenon can be explained by the fact that an embryo developing in vivo is naturally exposed to constant vibrations of around 6Hz with the periodically repeating increase to 20Hz. This review covers the history of this question and in this light offers an explanation through biological concept for one of the most recent developments in this area: in-vitro culture of human embryos with mechanical micro-vibration. The effect of mechanical micro-vibration on embryos during their in-vitro culture was examined. Pregnancy rates after the transfer of embryos in the group with in-vitro culture under mechanical vibration were increased.

RESUMEN

Great advances in the oncological therapy of childhood and adolescent cancer patients lead to an increase of young cancer survivors with a normal expectancy of life. The aggressive chemotherapy and/or radiation often compromises endocrine function with consecutive menopausal symptoms and sterility. Recently, new approaches were developed to preserve fertility with different methods to restore the ovarian function. The present review gives an overview of the current possibilities, which may be offered to these young cancer patients, as well as the chances of success and risks and the unsolved issues in special situations.
