Endometriosis Predictive Models Based on Self-Assessment Questionnaire, Evidence from Clinical Examination or Imaging Findings: A Narrative Review.

OBJECTIVE: The aim of this narrative review is to evaluate existing questionnaires on predictive models for endometriosis. These symptom-based models have the potential to serve as screening tools for adult women to detect endometriosis. DATA SOURCES: A comprehensive search of PubMed and Embase databases was conducted to identify studies on endometriosis screening. SELECTION OF STUDIES: The search targeted predictive models for endometriosis localisation, bowel involvement, need for bowel surgery and fertility. Due to the heterogeneity identified, a systematic review was not possible. A total of 23 studies were identified. DATA EXTRACTION AND SYNTHESIS: Among these studies, twelve included measures for general endometriosis, two targeted specific sites, four focused on deep infiltrating endometriosis (DIE), and three addressed the need for endometriosis-related bowel surgery. Many measures combined clinical, imaging and laboratory tests with patient questionnaires. Validation of these models as screening tools was lacking in all studies, as the focus was on diagnosis rather than screening. CONCLUSION: This review did not identify any fully validated, symptom-based questionnaires for endometriosis screening in adult women. Substantial validation work remains to establish the efficacy of such tools.

Exploring Hormone Therapy Effects on Reproduction and Health in Transgender Individuals.

Transgender individuals often face elevated mental health challenges due to gender dysphoria, but gender-affirming treatments such as surgery and hormone therapy have been linked to significant improvements in mental well-being. The potential influence of time and circadian rhythms on these treatments is prevalent. The intricate interplay between hormones, clock genes, and fertility is profound, acknowledging the complexity of reproductive health in transgender individuals. Furthermore, risks associated with gender-affirming hormonal therapy and potential complications of puberty suppression emphasize the importance of ongoing surveillance for these patients and the need of fertility preservation and family-building options for transgender individuals. This narrative review delves into the intricate landscape of hormone therapy for transgender individuals, shedding light on its impact on bone, cardiovascular, and overall health. It explores how hormone therapy affects bone maintenance and cardiovascular risk factors, outlining the complex interplay of testosterone and estrogen. It also underscores the necessity for further research, especially regarding the long-term effects of transgender hormones. This project emphasizes the critical role of healthcare providers, particularly obstetricians and gynecologists, in providing affirming care, calling for comprehensive understanding and integration of transgender treatments. This review will contribute to a better understanding of the impact of hormone therapy on reproductive health and overall well-being in transgender individuals. It will provide valuable insights for healthcare providers, policymakers, and transgender individuals themselves, informing decision-making regarding hormone therapy and fertility preservation options. Additionally, by identifying research gaps, this review will guide future studies to address the evolving healthcare needs of transgender individuals. This project represents a critical step toward addressing the complex healthcare needs of this population. By synthesizing existing knowledge and highlighting areas for further investigation, this review aims to improve the quality of care and support provided to transgender individuals, ultimately enhancing their reproductive health and overall well-being.

Hysteroscopic features suggestive of chronic endometritis: a systematic review.

The purpose of this systematic review is to identify common hysteroscopic findings suggestive of endometritis, chronic or subclinical, based on current scientific evidence. Data sources were MEDLINE, Embase, PubMed and other sources of grey literature. Four (4) authors independently selected studies addressing hysteroscopic detection of CE based on specific and clearly stated hysteroscopic criteria. The diagnosis was confirmed by histologic assessment, as stated in the materials and methods of these studies included. The initial search identified 599 studies, of which 21 met the inclusion criteria. Significant heterogeneity among published studies on Chronic endometritis (CE) remains the main limitation in performing a metanalysis and further analysis of diagnostic accuracy on the subject. Hysteroscopy is an important diagnostic tool in cases of chronic endometritis when accompanied by endometrial biopsies. Clinicians relate hyperaemia and endometrial oedema with chronic endometritis while more than half include micropolyposis as a pathognomonic feature of this subclinical condition. Micropolyps, stromal oedema, haemorrhagic spots, strawberry aspect, and hyperaemia are proposed as adequate indicators of hysteroscopic evidence of CE according to the literature. The impact of CE in long-term reproductive outcomes remain unclear, thus clinicians ought to communicate this to the patients and provide treatment where clinically appropriate. In addition, we present hysteroscopic images of histologically confirmed CE cases that could play the role of a hysteroscopic atlas.

Fertility preservation in patients with gynaecologic malignancy: Response to ovarian stimulation and long-term outcomes.

OBJECTIVE: To the best of our knowledge, the available evidence on the effect and efficacy of controlled ovarian stimulation (COS) in this group of patients remains poorly reported. Concerns related to the impact of stimulation to cancer progression and recurrence, as well as the risk of disease dissemination during egg collection, might explain the aforementioned trend. METHODS: Overall, our FP Service received 192 gynaecological referrals, between 2005 and 2021, regarding gynaecologic conditions mainly cancer related. A total of 68 (35.4%) patients underwent COS. These patients were diagnosed with the following gynaecologic pathologies: 33 cases (48,5%) of cervical cancer were noted (stage 1b1-2b), 25 ovarian pathology (36.7%), 9 cases (13.2%) of endometrial cancer, and a single case of vaginal cancer (1.5%). RESULTS: The mean age of patients attending the fertility preservation service was 31.5 (std 5.8). The patients presenting to their initial appointment with a mean BMI 24.5 (IQR 6.9) and a median AFC of 12 (IQR 13). The mean duration of COS was 11 days (IQR 3), and the median dose of gonadotrophins was calculated at 300 IU (IQR 75 IU). In 95.4% of the cases, GnRH agonist was used as a trigger for final maturation. The median number of follicles measuring more than 14 mm at the time of trigger was 11 (IQR 8), whereas the median number of oocytes collected was 11 (IQR 9). The complication rate was reported at less than 2%. So far, one in four women of this FP group (17/68, 25% of the overall group) returned to our service to claim their cryopreserved eggs/embryos and successful livebirths were reported in 58.8% of this sample (10/17 cases). The mean time to return to use their oocytes/embryos was 36 months (min value 16 months - max value 85 months). There was no significant difference in mortality rate between patients who received FP vs those who did not (hazard ratio of mortality was estimated at 0.91 (p-value 0.88)). CONCLUSION: Based on our findings, ovarian stimulation for patients presenting with gynaecologic malignancy is a safe and efficient method of fertility preservation. Undoubtedly, the sample size is limited, however our results are reassuring and highlight the efficacy of COS for the purpose of FP based on data coming from the largest Assisted Conception Unit of the South-East of the UK.

Psychometric properties of the Greek versions of the Pandemic-Related Pregnancy Stress Scale and the Pandemic-Related Postpartum Stress Scale and associated risk factors during the second year of the COVID-19 pandemic.

BACKGROUND: The COVID-19 pandemic has affected perinatal mental health. Reliable tools are needed to assess perinatal stress during pandemic situations. AIMS: To assess the psychometric properties of the Greek versions of the Pandemic-Related Pregnancy Stress Scale (PREPS) and the Pandemic-Related Postpartum Stress Scale (PREPS-PP) and to explore the associations between women's characteristics and perinatal stress during the second pandemic wave. METHODS: The PREPS and PREPS-PP were completed by 264 pregnant and 188 postpartum women, respectively, who also completed the State-Trait Anxiety Inventory (STAI) and the Edinburgh Perinatal Depression Scale (EPDS). RESULTS: The internal consistency was similar for PREPS and PREPS-PP. It was good for preparedness stress (a = 0.77 and α = 0.71, respectively) and infection stress (α = 0.83 for both scales) but low for positive appraisal (α = 0.46 and α = 0.41, respectively). Of the pregnant women, 55.33% and 55.27%, respectively, reported scores of ≥40 on STAI-S and STAI-T, and the respective percentages for the postpartum women were 47.34% and 46.80%. In addition, 14.39% of the pregnant women and 20.74% of the postpartum women scored ≥13 on the EPDS. Higher preparedness stress on PREPS and PREPS-PP was associated with primiparity (P = 0.022 and P = 0.021, respectively) and disrupted perinatal care (P = 0.069 and P = 0.007, respectively). In postpartum women, higher infection stress was associated with chronic disease (P = 0.037), primiparity (P = 0.02) and perceived risk of infection (P = 0.065). Higher score on infection stress was associated with disrupted perinatal care in both groups (P = 0.107 and P = 0.010, respectively). CONCLUSIONS: The Greek versions of PREPS and PREPS-PP are valid tools for the assessment of women at risk of perinatal stress during a health crisis.

Ovarian Teratomas in Children and Adolescents: Our Own Experience and Review of Literature.

Background: Ovarian teratomas are the most common type of ovarian mass during childhood and adolescence. There is no clear guidance for the management of the ovarian teratomas in children and adolescents. It is necessary, however, to understand the feature of these tumours and the indications for operating on them, and to put subjective criteria for the management in elective or emergency presentations. Methods: Medical records of patients between the age of 12 and 20 years old that underwent surgery for ovarian teratomas at the Department of Obstetrics and Gynaecology in University Hospital of Ioannina, between January 2000 and August 2022, were reviewed. A medical database was searched between January 2000 and August 2022 with the following keywords: ovarian teratoma, paediatrics and adolescents. Results: We present the results of forty patients, with a mean age of 11.8 years of age. All patients had surgery, where three out of four underwent oophorectomy and only one out of four underwent ovary-sparing operation; similar results were found in the literature. Conclusion: Ovary-sparing treatment is more common recently compared with the past, such as MIS compared with laparotomy. Better-organised and -planned prospective multi-centre studies are necessary to gain a deeper knowledge of the physiology and prognostic factors of teratomas in children.

The WHOQOL-BREF instrument: Psychometric evaluation of the Greek version in patients with advanced cancer and pain and associations with psychological distress.

OBJECTIVES: Assessment of the psychometric characteristics of the Greek version of the brief World Health Organization Quality of Life Instrument (WHOQOL-BREF) in patients with advanced cancer and pain, and exploration of the association between psychological distress and quality of life (QoL). METHOD: The sample consisted of 145 patients with advanced cancer and pain who completed the WHOQOL-BREF, the Symptom Checklist-90 (SCL-90), and the Pain Visual Analogue Scale (VAS). In analysis, the following methods were used: Cronbach's alpha, Item Response Theory (IRT), polychoric, Pearson and polyserial correlation, t-test, and Linear regression. RESULTS: The internal consistency was high for all domains of the WHOQOL-BREF (Cronbach's α ≥ 0.731). Similarly, with the exception of three items, the WHOQOL-BREF items has large discrimination parameters suggesting that they have a high ability in differentiating subjects. On SCL-90, the three dimensions with the highest scores were Depression, Somatization, and Anxiety. The overall score for psychological distress, the Global Severity Index (GSI), showed significant negative association with all the WHOQOL-BREF factor scores (Physical Health: B = -1.488, p < 0.001, Psychological Health: B = -1.688, p < 0.001, Social Relationships: B = -0.910, p < 0.001, Environment: B = -1.064, p < 0.001). Male gender was associated with lower scores for Social Relationships (B = -0.358, p = 0.007) and Environment (B = -0.293, p = 0.026). SIGNIFICANCE OF RESULTS: The Greek version of the WHOQOL-BREF showed good psychometric properties in patients with advanced cancer and can be used as a reliable instrument in clinical practice. The level of psychological distress can be considered a determinant of QoL in patients with advanced cancer and pain, independently of pain intensity or other clinical characteristics. In cancer, the disease process can activate multiple physiological and psychological mechanisms that lead to a wide range of symptoms of psychological distress. To improve their QoL, psychological intervention focused on the identification and alleviation of psychological distress in patients with advanced cancer, and help in finding meaning in their experience, should be provided.

Can maternal hormones play a significant role in delivery mode?

The aim of this study was primarily to evaluate the levels of progesterone, oestradiol and relaxin during different delivery modes and secondarily to assess specific traits and changes in maternal pelvic dimensions during pregnancy and childbirth, in correlation with foetal size and maternal hormonal profile. Nulliparous women (n = 448) were evaluated at three different stages, during first trimester, at the time of admission for childbirth and finally just before childbirth. Each examination included clinical internal pelvimetry, blood sample collection for defining the hormones levels in peripheral maternal circulation and ultrasonographic measurements of specific variables of the pubic symphysis and the foetus. We included 304 nulliparous women divided in three groups. According to our results, there was statistically significant difference at the mean progesterone, oestradiol and relaxin range during different modes of childbirth (p-value < .01). We also found significant correlation between the newborn's weight and the changes in pubic symphysis dimensions. However, no significant association was noted between maternal hormones studied and the changes in pelvic dimensions.IMPACT STATEMENTWhat is already known on this subject? Mode of childbirth can be affected by various aspects, like maternal pelvic anatomy, foetal size and hormonal status at the time of labour. Hormonal fluctuations along with mechanical forces caused by the foetus are believed to lead to morphological alterations to promote natural vaginal childbirth.What do the results of this study add? Our results clearly showed that successful vaginal delivery is characterised by the prevalence of a hyperoestrogenic environment with higher values of intrapartum oestradiol range and significant increase in maternal serum relaxin levels. We also proved that progesterone levels do not decrease during vaginal childbirth, and we concluded that foetal size seems to be the most crucial factor causing alterations in maternal pelvis during parturition.What are the implications of these findings for clinical practice and further research? Our findings could form part of a set of key factors included in future algorithms or computerised biomechanical models for predicting potential childbirth mode. Larger multicenter studies should confirm our results and evaluate their clinical significance in the decision making to ensure safe childbirth and optimal maternal and perinatal outcomes.

Prevalence of postpartum depression and antenatal anxiety symptoms during COVID-19 pandemic: An observational prospective cohort study in Greece.

INTRODUCTION: A significant proportion of pregnant women and women in the early postpartum period suffer from mental health problems. The COVID-19 pandemic represents a unique stressor during this period and many studies across the world have shown elevated rates of postpartum depression (PPD). METHODS: In this multicenter two-phase observational prospective cohort study, we aim to assess the prevalence of anxiety prior to labor (Generalized Anxiety Disorder-7), as well as PPD at 6-8 weeks postpartum using the Edinburgh Postnatal Depression Scale (EPDS). RESULTS: Of the 330 women analyzed, 13.2% reported symptoms of depression using EPDS cut-off score ≥13. High antenatal levels of anxiety (24.8% scored ≥10 in GAD-7) were documented. A significant proportion of postpartum women reported a decrease in willingness to attend antenatal education courses (36%) and fewer antenatal visits to their obstetrician (34%) due to pandemic. Higher antenatal anxiety increased the odds of being depressed at 6-8 weeks postpartum (EPDS ≥13). CONCLUSIONS: Compared to reported prevalence of PPD from previous studies before the COVID-19 era in Greece, we did not find elevated rates during the first wave of the pandemic. High anxiety levels were observed indicating that there is a need for close monitoring in pregnancy during the pandemic and anxiety screening to identify women who need support in the pandemic era. A well-planned maternity program should be employed by all the associated care providers to maintain the proper antenatal care adjusted to the pandemic strains as well as a follow-up after labor.

Uterine sparing management in patients with endometrial cancer: a narrative literature review.

Endometrial cancer is the most common malignancy of the female genital tract. Approximately 25% of cases occur in premenopausal women, and up to 5% of cases occur in women who are younger than 40 years old. The survival rate in these cases is 99%; therefore, uterine-sparing management could be considered under strict criteria selection and the strong desire of the woman to preserve uterus and fertility. Diagnosis should be performed after a hysteroscopic biopsy instead of dilatation and curettage. The highest remission rate was achieved after combining a hysteroscopic resection with hormonal therapy compared to single hormonal treatment. The most common regiments are the following progestins: megestrol acetate (MA) and medroxyprogesterone acetate (MPA) taken orally with a daily dosage of 160 mg-320 mg for MA and 250 mg-600 mg for MP. Evaluations at three and six months could be performed by office endometrial biopsy and/or hysteroscopic directed biopsy especially in the presence of levonorgestrel intrauterine system, and in cases of remission, either a pregnancy attempt or maintenance therapy should be considered. After childbearing, hysterectomy with bilateral salpingo-oophorectomy is recommended, whereas ovarian preservation could be considered depending on the patient's age and whether they fulfil the strict criteria selection.

Phthalates and fetal growth velocity: tracking down the suspected links.

Fetuses that have not achieved their full growth potential are associated with adverse perinatal and long-term outcomes; thus, it is essential to identify environmental factors that can potentially impair normal intrauterine development. Endocrine disrupting compounds (EDCs), substances capable of altering the homeostasis of the endocrine system, are thought to play a role in restriction of growth velocity, with phthalates being among the most common EDCs to which pregnant women are exposed. Such exposure can potentially lead to changes to the epigenome, placental structure, and hormone function and trigger oxidative stress. Given that these pathways have been linked to fetal growth restriction, we reviewed the literature on the relationship between phthalates and fetal growth. The majority of the studies, which used birth weight as an indicator of intrauterine development, showed contradictory results, the main reason being the EDCs' rapid metabolism. However, we can draw more consistent conclusions when phthalates are quantified at more than one time point during pregnancy. In this narrative review, we present current data indicating the role of phthalates, and especially di-(2-ethylhexyl) phthalate (DEHP), in abnormal fetal growth velocity.

Autonomic Responses during Labor: Potential Implications for Takotsubo Syndrome.

Takotsubo syndrome is a serious complication of labor. Although the pathophysiologic role of excessive sympathetic activation is established in this process, concurrent vagal responses have not been adequately described. Moreover, it remains unclear whether autonomic activity depends on the mode of delivery. Here, we explored the hypothesis that the different management of cesarean and vaginal delivery may elicit diverse responses affecting both autonomic arms. For this aim, continuous electrocardiographic recording was performed in 20 women during labor, and non-invasive indices of sympathetic and vagal activity were compared between the two modes of delivery. We report sympathetic prevalence during cesarean delivery, caused by marked vagal withdrawal, whereas autonomic activity was rather stable during vaginal delivery. These differences may be attributed to the effects of anesthesia during cesarean delivery, along with the protective effects of oxytocin administration during vaginal delivery. Our results provide further insights on autonomic responses during labor that may prove useful in the prevention of complications, such as takotsubo syndrome.

Management of recurrent miscarriages: an overview of current evidence.

PURPOSE OF REVIEW: Recurrent miscarriage (RM) or recurrent pregnancy loss (RPL) is defined as the consecutive loss of two or more pregnancies before the age of viability. The exact prevalence of RM is unknown, but it has been reported between 1% and 2%. The objective of this review is to provide a critical summary of the latest evidence for the investigation and management of women with RM. RECENT FINDINGS: RMs are associated with multiple factors including increased female age and lifestyle habits, as well as genetic factors, hereditary and acquired thrombophilia and infections. Metabolic and endocrine factors, in addition to anatomical causes such as uterine malformations have also been suggested as a causative factors of RM. SUMMARY: The management of RM would be expected to cause specific, however, in the majority of the cases no cause is identified, and the factors associated with RM may not be causally related with the condition.

Hysteroscopic detection of chronic endometritis: Evaluating proposed hysteroscopic features suggestive of chronic endometritis.

PURPOSE: To evaluate the proposed criteria in a large sample and in additional subgroups in order to test the validity of the hysteroscopic features widely-accepted as suggestive of CE. METHOD(S): All patients (n: 2675) underwent outpatient hysteroscopy, with the vaginoscopic approach technique. Hysteroscopic features such as, stromal oedema, diffuse or focal hyperaemia, "strawberry aspect", micropolyposis and endometrial polyps, are often indicate the presence of chronic endometritis. All hysteroscopic features, alone and in combination were applied in 7 (seven) different subgroups of the sample: total sample, women in reproductive age, women with infertility issues/IVF screening, women with history of recurrent miscarriages, menopausal women, and women with hysteroscopic indication of Abnormal Uterine Bleeding (AUB) in women of reproductive age and postmenopausal bleeding (PMB). From each case, endometrial samples were obtained and immunohistochemistry, identifying CD-138, was applied in order to diagnose CE. RESULT(S): A total of 2675 patients were included of which, 1444 women were found with at least one of the proposed hysteroscopic features mentioned above. Stromal oedema, focal or diffuse hyperaemia and "strawberry aspect" in combination with micropolyposis demonstrated higher rates of diagnostic accuracy in the detection of CE correlated to histologic confirmation. Micropolyposis, stromal oedema, focal or diffuse hyperaemia and "strawberry aspect" offer great diagnostic accuracy in the hysteroscopic detection of Chronic Endometritis, regardless reproductive status and/or clinical presentation. Endometrial polyps are not valid hysteroscopic features in cases of suspected CE. CONCLUSION(S): Diagnostic hysteroscopy can accurately diagnose cases of CE, based on stromal oedema, focal or diffuse hyperaemia and "strawberry aspect", in combination with micropolyposis. In subgroups of infertile women, higher diagnostic accuracy based on the hysteroscopic features mentioned, was more likely to be achieved. Whether endometrial polyps are suggestive of CE, when identified during office hysteroscopy, remains controversial.

The Effect of Thyrotropin-Releasing Hormone and Antithyroid Drugs on Fetal Thyroid Function.

A euthyroid pregnant woman will normally have a fetus that displays normal fetal development. However, studies have long demonstrated the role of T3 (Triiodothyronine), T4 (Thyroxine), and TSH (Thyroid Stimulating Hormone) and their degree of penetrability into the fetal circulation. Maternal thyrotropin-releasing hormone (TRH) crosses the placental site and, from mid-gestation onward, is able to promote fetal TSH secretion. Its origin is not only hypothalamic, as was believed until recently. The maternal pancreas, and other extraneural and extrahypothalamic organs, can produce TRH variants, which are transported through the placenta affecting, to a degree, fetal thyroid function. Antithyroid drugs (ATDs) also cross the placenta and, because of their therapeutic actions, can affect fetal thyroid development, leading in some cases to adverse outcomes. Furthermore, there are a number of TRH analogues that share the same properties as the endogenous hormone. Thus, in this narrative review, we highlight the interaction of all the above with fetal growth in uncomplicated pregnancies.

Psychological burden of covid-19 health crisis on health professionals and interventions to minimize the effect: what has history already taught us?

Health professionals have been at the frontline of the health service since the outbreak of covid-19, responding promptly to diagnose, support and treat infected patients. World Health Organization (WHO) has already praised their contribution and their essential role in controlling this disease. Some of the main concerns of covid-19's impact to health service staff include work overload, exhaustion, and high risk of self-infection or transmission to family members. Moreover, during the pandemic, caregivers' mental health inevitably becomes vulnerable, with salient stress and anxiety-related symptoms. Uncertainty, fear of contagion, guilt, hopelessness, stigmatization and, in some cases, long-term post-traumatic stress disorder (PTSD) are few of the potential effects posed by this outbreak on health workers. In this review, lessons learnt from previous global crises or pandemics on the psychological impact of health workers are presented. History could potentially provide essential information on how to best manage, support and optimize our approach to this highly appreciated and much needed group of professionals. Targeted and prompt interventions could reduce the psychological strain of health professionals, thus, further improving provided patient care. Covid-19 is an on-going health crisis and this work, even though generated by limited existing data, could be used to inform governments and/or institutions and lead on decisions and changes in current guidelines.

Integrating Lifestyle Focused Approaches into the Management of Primary Dysmenorrhea: Impact on Quality of Life.

OBJECTIVE: This narrative review aims to identify alternative ways to improve the symptoms of primary dysmenorrhea (PD). BACKGROUND: PD refers to endometrial painful cramps during the premenstrual period. This condition affects a lot of women worldwide and is accompanied with absenteeism and high economic costs, thus, risk-free, and effective therapeutic approaches are needed. Pharmacological agents such as non-steroidal anti-inflammatory drugs (NSAIDs) and oral contraceptive pills (OCPs), which are widely prescribed for these women, demonstrate adequate efficacy in alleviating pain and discomfort. The long natural course of the disease dictates remedies that focus on lifestyle changes and on improvement of Quality-of-Life (QoL) for women suffering with PD. MATERIALS AND METHODS: Five major search engines, namely MEDLINE, PubMed, EMBASE, and Cochrane Library were searched for articles published prior to October 2020 focused in PD. A total of 74 paper were included. DISCUSSION: Physical activity, for instance yoga, aromatherapy massage, and other forms of relaxation, vitamins and dietary changes, acupressure and acupuncture,a and some psychological interventions are just few of the proposed health behavior targeted approaches in cases of PD. This review focuses on lifestyle changes and alternative methods that could potentially result in minimizing symptoms of PD and in improving overall QoL for these patients, by providing current scientific evidence on their efficacy. CONCLUSION: Complementary and alternative medicine practices (CAM) are widely accepted by women. International literature provides controversial scientific evidence, thus further studies need to be conducted in order to prove or disregard their efficacy in cases of PD.

Comparative retrospective study on transvaginal sonography versus office hysteroscopy in the diagnosis of endometrial pathology among different subgroups.

BACKGROUND: Transvaginal sonography (TVS) and office hysteroscopy are considered essential diagnostic tool for the gynecologic everyday practice. Through the years equipment developments in both techniques along with cumulative experience gained by the gynecologists result in a disunity among clinicians in choosing optimal diagnostic approach with regards to endometrial pathology. AIM: To evaluate the diagnostic accuracy of TVS versus office hysteroscopy (OHSC) in detecting endometrial pathology. Results were compared to available scientific evidence available among similar published studies. METHODS: Comparative Retrospective study performed at the Endoscopic Unit, Department of Gynecology, University Hospital of Ioannina, Greece. A total of 2675 cases were collected for this study from January 1997 until August 2019. All cases recruited underwent a TVS followed by office hysteroscopy (OHSC) for various indications according to the local protocol. Endometrial samples from all cases were obtained and histology confirmed the diagnosis. Sonographic and hysteroscopic results were correlated with histologic reports to assess the diagnostic accuracy of both techniques. RESULTS: In a total of 2675 cases recruited for this study, 23.2% were postmenopausal while the majority (76.7%) was of reproductive age. The commonest indication for hysteroscopy was abnormal uterine bleeding (AUB) accounting for 29.7% of the cases. Overall, TVS demonstrated diagnostic accuracy of 84.7%% in detecting endometrial pathology, compared to 97.3% of OHSC. Sensitivity, specificity, positive prognostic value (PPV) and negative prognostic value (NPV) of TVS detecting endometrial pathology were 84.0, 86.8, 95.3 and 63.0%, respectively. The corresponding values for hysteroscopy were 98.9, 95.1, 98.4 and 93.9%, respectively. Diagnostic value of both techniques was estimated in 6 (six) additional subgroups: total sample with AUB, women of reproductive age, women of reproductive age with AUB, women of reproductive age with infertility issues, postmenopausal women and postmenopausal women suffering from postmenopausal bleeding (PMB). All values were calculated with regards to histologic findings as gold standard technique. All results were correlated with scientific evidence collected from the international literature. CONCLUSION: Office hysteroscopy is a more reliable tool in detecting endometrial pathologies compared to TVS regardless of reproductive status or clinical presentation. TVS is likely to orientate and guide specialists on what to expect prior to an hysteroscopic intervention.

Immune cells in normal pregnancy and gestational trophoblastic diseases.

A healthy pregnancy requires the development of maternal-fetal immune tolerance against the semi-allogeneic fetus. The interactions between the trophoblastic cells and the maternal immune cells (p.e., natural killer cells, T cells, macrophages, dendritic cells and B-cells) are important for the development of the maternal-fetal immune tolerance and the placental growth and function. These interactions are mediated by cell to cell contact and secreted molecules such as cytokines, chemokines, angiogenic factors and growth factors. The maternal immune cells are present in normal non-pregnant and pregnant endometrium and there are several lines of evidence based on immunohistochemical and RNA sequencing data that the decidual immune cells and immune-related pathways display alterations in GTD, which may have pathogenetic and clinical significance. The present review focuses on the usefulness of the immunohistochemical analysis which provides multiparametric in situ information regarding the numbers, the immunophenotypes and the immunotopographical distributions of the decidual immune cells in tissue sections from normal pregnancy and GTD. We also discuss the significance of the immunohistochemical information in order to gain insight in the putative mechanisms explaining the alterations of the decidual immune cells in GTD and the potential implications of these alterations in the pathogenesis and the clinical behavior of GTD.

"Silent" post-menopausal genital tuberculosis with lethal outcome.

Female genital Tuberculosis (TB) is a rare disease, that usually affects female patients of reproductive age living in developing countries. The diagnosis of the disease is quite difficult since there is no consensus on the appropriate screening and management needed. Female genital TB can mimic many other pathologies including advanced ovarian cancer. Laboratory findings or blood serum tests usually are not suggestive of the disease. Imaging findings can be misleading. The incidence of the disease in Greece is rare. We present a rare case report of a post-menopausal patient with female genital TB, mimicking malignancy and resulting to a lethal outcome. Laboratory and imaging findings were non-specific for the disease, leading to a false diagnosis of disseminated peritoneal carcinomatosis.
