RESUMO

OBJECTIVE: Two-dimensional (2D) transvaginal ultrasound (TVS) is an accessible and cost-effective diagnostic tool for the detection of adenomyosis. Different ultrasound features related to adenomyosis have been described, but the predictive value of each ultrasound sign and their combinations requires further investigation. We aimed to analyze the accuracy of 2D-TVS and describe possible combinations of ultrasound signs with a high predictive value in the diagnosis of adenomyosis. METHODS: This was a prospective multicenter study of patients scheduled for laparoscopic hysterectomy who had been examined using standardized 2D-TVS at nine expert centers specializing in the diagnosis and treatment of endometriosis. 2D-TVS examination included nine typical adenomyosis ultrasound features, comprising heterogeneous myometrium, myometrial linear striations, myometrial cysts, subendometrial microcysts, asymmetrical myometrial thickening, uterine enlargement, the 'question mark sign', thickening of the junctional zone and hyperechoic myometrial spots, in order to predict or exclude the presence of adenomyosis. Ultrasound examination results were compared with histology after hysterectomy. The diagnostic reliability of the nine ultrasound signs and their combinations, and the influence of concurrent fibroids on the accuracy of the results, were analyzed. RESULTS: A total of 202 patients were enrolled into the study. Histopathological examination revealed adenomyosis in 130 patients (64.4%). The accuracy of prediction of adenomyosis by 2D-TVS examination using all signs was 63.4% (positive predictive value, 71.5%; negative predictive value, 48.6%; sensitivity, 71.5%; specificity, 48.6%). Heterogeneous myometrium, myometrial cysts, subendometrial microcysts and hyperechoic myometrial spots showed the highest accuracy (55.7-62.1%) as individual ultrasound signs for the prediction of adenomyosis. The combination of the most accurate ultrasound signs (subendometrial microcysts, myometrial cysts and heterogeneous myometrium) improved the specificity of prediction (86.1%) when compared with that of these three single markers (35.2-81.7%). Uterine enlargement and asymmetry showed both low sensitivity (60.8% and 52.3%, respectively) and specificity (41.7% and 49.3%, respectively) as individual sonographic signs. CONCLUSIONS: Heterogeneous myometrium, myometrial cysts, subendometrial microcysts and hyperechoic myometrial spots showed the highest accuracy for the detection of adenomyosis in this study, while uterine enlargement and asymmetry led to high false-positive and false-negative results. A combination of ultrasound features including the most accurate signs increases specificity. © 2023 The Authors.

RESUMO

Introduction Minimally invasive operative techniques are being used increasingly in gynaecological surgery. The expansion of the laparoscopic operation spectrum is in part the result of improved imaging. This study investigates the practical advantages of using 3D cameras in routine surgical practice. Materials and Methods Two different 3-dimensional camera systems were compared with a 2-dimensional HD system; the operating surgeon's experiences were documented immediately postoperatively using a questionnaire. Results Significant advantages were reported for suturing and cutting of anatomical structures when using the 3D compared to 2D camera systems. There was only a slight advantage for coagulating. The use of 3D cameras significantly improved the general operative visibility and in particular the representation of spacial depth compared to 2-dimensional images. There was not a significant advantage for image width. Depiction of adhesions and retroperitoneal neural structures was significantly improved by the stereoscopic cameras, though this did not apply to blood vessels, ureter, uterus or ovaries. Conclusion 3-dimensional cameras were particularly advantageous for the depiction of fine anatomical structures due to improved spacial depth representation compared to 2D systems. 3D cameras provide the operating surgeon with a monitor image that more closely resembles actual anatomy, thus simplifying laparoscopic procedures.

RESUMO

Introduction: Pelvic pain is a common problem in gynaecological practice. It is often unclear whether definite causality exists between reported symptoms and objective clinical findings of the female genital tract, and medical or operative treatments do not always achieve long-term resolution of symptoms. Methods: This pilot study investigated 28 patients (age 20-65, median 36.5 years) from a gynaecology practice whose only clinical finding was painful pelvic floor muscle tightness. Following standardised gynaecological and physiotherapist examination, all patients received osteopathic treatment. Pain had been present for a median of 3 years (range 1 month to 20 years). 14 patients had previously confirmed endometriosis. Treatment success was evaluated on consultation with patients in person or in writing. Results: 22 of the 28 participants completed the treatment according to plan. Overall, 17 reported symptom improvement, while 10 of the 14 patients with endometriosis did. Conclusion: Osteopathy is well received by women with painful pelvic floor muscle tightness and appears to be an effective treatment option.

RESUMO

BACKGROUND: Chronic pelvic pain in women represents a difficult diagnostic and therapeutic problem in the gynecological practice which is always a challenge when dealing with affected women. GYNECOLOGICAL CAUSES: Possible gynecological causes are endometriosis, adhesions and/or pelvic inflammatory disease (PID), pelvic varicosis and ovarian retention syndrome/ovarian remnant syndrome. Other somatic causes are irritable bowel syndrome, bladder pain syndrome, interstitial cystitis and fibromyalgia. PSYCHOSOCIAL FACTORS: Psychosocial causes contributing to chronic pelvic pain are a high comorbidity with psychological factors, such as anxiety disorders and substance abuse or depression but the influence of social factors is less certain. The association with physical and sexual abuse also remains unclear. DIAGNOSTICS AND THERAPY: Important diagnostic steps are recording the patient history, a gynecological examination and laparoscopy. Multidisciplinary therapeutic approaches are considered to be very promising. Basic psychosomatic care and psychotherapy should be integrated into the therapeutic concept at an early stage.

RESUMO

OBJECTIVES: The aim of the current study was to evaluate the prevalence and the impact of sexual dysfunction, sexual distress and interpersonal relationships in patients with endometriosis. STUDY DESIGN: A questionnaire-based multicentre cohort study was conducted in eight tertiary referral centres in Austria and Germany. One hundred and twenty-five patients with histologically proven endometriosis and dyspareunia were included. The Female Sexual Function Index and the Female Sexual Distress Scale were used to screen women's sexuality. Additionally, we evaluated psychological parameters and pain intensity during/after sexual intercourse via a self-administered questionnaire. RESULTS: Female sexual distress and sexual dysfunction were observed in 97/125 and 40/125 patients. Statistically significant correlations were found between sexual dysfunction and pain intensity during/after sexual intercourse (p<0.01/p<0.01), a lower number of episodes of sexual intercourse per month (p<0.01), greater feelings of guilt towards the partner (p<0.01) and fewer feelings of femininity (p<0.01). Thirty-eight out of 125 women agreed that the primary motivation for sexual intercourse was to conceive and nearly half of women (46%) included stated that satisfying the partner acted as primary motivation for sexual contact. CONCLUSION: Overall, our findings demonstrate that dyspareunia as a common complaint in patients with endometriosis causes a severe impairment of sexual function, relationship and psychological wellbeing.

RESUMO

The idea of quality improvement in the management of endometriosis has been brought to attention throughout Europe. This - first and foremost - includes the implementation of centers specialized in treating endometriosis. This leads to qualification of both physicians and other medical staff, enforcement of research efforts, and informing the patients, the public, politicians, healthcare providers, and industry. Given limited budgets, focusing on the existing national commitment may be the first step.

RESUMO

The ENZIAN-Score is presented as a new instrument to classify the deep infiltrating endometriosis. Especially the retroperitoneal part of the severe endometriosis is focussed on. In analogy to an oncological staging four different stages are pronounced. The localisation and the expansion of the endometriosis nodule was indicated to different subgroups. The still used rAFS-score is of no clinical evidence, as we pointed out in a retrospective study of our patients with severe intestinal endometriosis.

RESUMO

As well as providing reliable contraception, modern low-dose oral contraceptives may offer some non-contraceptive advantages. Positive effects on problems such as edema with weight increase and breast tenderness, bloating, dysmenorrhea, and an improvement in skin and hair condition have been reported in several studies using an oral contraceptive containing drospirenone. If these disorders are cycle-dependent, use of the contraceptive in an extended regimen may be of additional benefit. The study reported in this paper followed 1433 women, 175 of whom took the drospirenone-containing pill continuously for between 42 and 126 days. Some symptoms of the premenstrual syndrome were influenced very satisfactorily by administration in an extended regimen.

RESUMO

Malignant tumors arising from endometriosis are rare. A frequency of about 1% has been reported with in 80% the ovary, and in 20% extragonadal sites being affected. The most common extragonadal manifestations are the rectosigmoid and the rectovaginal septum. For extragonadal malignant tumors arising from endometriosis, complete resection followed by post-operative radiotherapy, possibly plus adjuvant progestin therapy, is the treatment of choice. Endometriosis-associated ovarian carcinomas are likely to present with lower stage disease and predominantly lower grade tumors. While their treatment follows that of common ovarian cancer, a poorer response to chemotherapy must be considered. As unopposed estrogen replacement therapy has been identified as a risk factor for the development of endometriosis-associated cancer, it is not recommended for hormone replacement therapy in women with a history of endometriosis. Loss of heterozygosity and mutations of the PTEN tumor suppressor gene may be early events of tumorigenesis. Endometriosis and its malignant transformation, perhaps, may serve as a suitable model in this regard. According to recent studies, endometriosis is associated with an increased relative risk of non-Hodgkin lymphoma.

RESUMO

Numerous medical, surgical, and combined therapies have been proposed in the management of endometriosis. This range of treatment options contrasts remarkably with the evidence regarding their respective proven success rates. An exact preoperative differential diagnosis as well as adherence to operative recommendations that have been established meanwhile are essential for optimal results of surgery.

RESUMO

OBJECTIVE: To determine whether alterations in the secretion and regulation of matrix metalloproteinases (MMPs) and their inhibitors are present in uterine endometrial cells from endometriosis patients. STUDY DESIGN: In an in vitro study, uterine endometrial cells from 19 regularly cycling women with and 32 without endometriosis were treated with diethyl stilbestrol, promegestone (R5020), interleukin-1 (IL-1) and tumor necrosis factor a (TNF-alpha). Culture supernatants were assayed for MMPs 1, 2, 3, and 9, and for tissue inhibitors of MMP (TIMP-1 and TIMP-2) by ELISA. RESULTS: MMP-3 was secreted in high concentrations, moderate concentrations were seen for MMP-1 and MMP-2, and very low concentrations for MMP-9. Substantially more TIMP-1 than TIMP-2 was secreted. MMP-1 and MMP-3 were uniformly attenuated by R5020, while MMP-2 was not influenced by hormone treatment. MMP-3 was upregulated by TNF-alpha in all samples while IL-1 only increased secretion in cells from endometriosis patients. CONCLUSION: The upregulation of MMP-3 by IL-1 may contribute to an increased invasiveness of uterine endometrial fragments in endometriosis patients.

RESUMO

Local invasiveness is an important prognostic factor in endometrial carcinoma. To study the role of two groups of secreted proteinases (serine proteinases and matrix metalloproteinases) in this process, we examined three endometrial cancer cell lines (Ishikawa HEC 1A, AN3CA) for their invasiveness in vitro. Additionally, we considered the secretion of urokinase type plasminogen activator (uPA), plasminogen activator inhibitor 1 and 2 (PAI-1 and PAI-2), as well as matrix metalloproteinases (MMP) 1, 2, 3, and 9, and their inhibitors TIMP-1 and TIMP-2. Compared to the highly invasive fibrosarcoma cell line HT 1080, Ishikawa displayed low and AN3CA moderate invasiveness, while HEC 1A cells were almost as invasive as HT 1080 cells. Ishikawa cells secreted the highest amounts of proteinases. Cytokine and steroid treatments upregulated MMP-1 in all cell lines while the effects were heterogeneous regarding other proteinases and inhibitors. No effect of these treatments on invasiveness could be detected. Both basal secretion and regulation of the proteinases tested in this set of experiments seem to be markers of differentiation rather than of invasiveness.

RESUMO

OBJECTIVES: (1) to demonstrate specificity of integrin function in endometrial cell adhesion; (2) to investigate their regulation by tumor necrosis factor alpha (TNF alpha) and interleukin-1 (IL-1); and (3) to detect differences between cells from patients with and without endometriosis. STUDY DESIGN: Endometrial cell cultures from ten patients with and 13 without endometriosis were tested for their expression of integrins alpha2beta1, alpha5beta1, alpha(v)beta3, and alpha4beta1 by immunocytochemistry and for their adhesion to collagen type IV, laminin, and fibronectin. RESULTS: Integrin expression was independent of cytokine treatment. Addition of antiintegrin antibodies inhibited adhesion. A significant increase in adhesion to laminin and fibronectin was seen in endometriosis after IL-1 treatment and additionally to collagen after TNF alpha. Cells from women without endometriosis showed a significant increase only to fibronectin. CONCLUSIONS: Human endometrial cells express functional integrins in vitro. TNF alpha and IL-1 had more pronounced effects on adhesion in endometriosis. Inflammatory cytokines in the peritoneal cavity may facilitate adhesion of retrogradely menstruated endometrial fragments in endometriosis.

RESUMO

To investigate the effect of medrogestone on bone mineral density (BMD) and bone turnover under conditions of estrogen withdrawal, premenopausal women with endometriosis were treated with goserelin (Zoladex), combined with either placebo (group A, n = 12) or 10 mg medrogestone (Prothil, group B, n = 11) for six months, and followed for an additional six months. Lumbar spine BMD was measured at 0 and 6 month. Markers of bone turnover were serum bone alkaline phosphatase (sBAP) and osteocalcin (sOC) by ELISA, and urinary total pyridinoline (uPYD) and deoxypyridinoline crosslinks (uDPD) by HPLC. Patients in both groups had a similar and significant decrease in BMD after 6 months (4%, p < 0.01). The time course of changes in bone turnover, in contrast, was different in both groups. In group A, crosslink excretion increased from one month onwards, while no changes were seen in group B. In group A, sBAP levels rose during treatment, while in group B, this rise was delayed until treatment was terminated. Additionally, group B showed an initial suppression of sBAP and sOC. In both groups, sOC increased after treatment was discontinued. Medrogestone at 10 mg/d does not prevent lumbar bone loss in premenopausal women under estrogen deprivation. In the medrogestone add back group, the changes in bone turnover are compatible with low turnover bone loss,as ooposed to a state of high turnover seen in the unopposed goserelin group. This effect may be due to glucocorticoid receptor mediated actions of medrogestone on bone.

RESUMO

This study was undertaken to investigate the influence of activated autologous blood therapy on immunological parameters and on the clinical outcome in patients with recurrent spontaneous abortion. In a prospective trial, 36 women with recurrent spontaneous abortion were treated with intramuscular reinjections of extracorporally haemolysed and ultraviolet irradiated autologous blood. A comprehensive immunological investigation revealed significant changes in lymphocyte subpopulations, plasma complement levels, mitogen stimulation and immunoglobulin levels during the treatment period. No side-effects were reported by the patients. From June 1994 to November 1995, 22 intrauterine and one extrauterine pregnancies occurred, resulting in 19 (86%) live births, two (9%) spontaneous abortions and one (4%) artificial abortion compared with a 64% live birth rate in the historical control group. We conclude that activated autologous blood therapy has detectable effects on the immune system, and seems to be promising for further investigation concerning the treatment of idiopathic recurrent spontaneous abortion.

RESUMO

BACKGROUND: Endometriosis is one of the most common benign gynaecological diseases, and attachment of retrogradely shed viable endometrial cells is considered to be important in its development. CD44 is a multifunctional adhesion molecule that undergoes alternative splicing, giving rise to different isoforms. METHODS: The expression of cell surface-associated CD44 std, v4, v5, v6 and v10 variants before and after cytokine treatment was investigated in endometrial cultures derived from 10 endometriosis patients and 22 women without the disease using immunocytochemistry. The immunoreactivity of soluble CD44 std, v5 and v6 variants was measured in culture medium using an enzyme immunoassay kit. RESULTS: We report on the presence of soluble CD44 in endometrial culture supernatants. In particular, circulating CD44 standard form levels were significantly higher than levels of splice variants. We also found that both epithelial and stromal cells express surface-associated CD44 molecules in a distinct pattern and that this expression is not modulated by tumour necrosis factor (TNF)-alpha or/and interleukin 1 (IL-1) alpha/beta. Finally, cell surface-associated as well as soluble CD44 expression was similar in the two groups. CONCLUSION: Our results indicate that endometrial cells can serve as a source of circulating CD44, but a direct role in the pathogenesis of endometriosis is rather improbable.

RESUMO

Essential features of endometrial physiology involve the extracellular matrix (ECM). In the pathogenesis of endometriosis, interactions of endometriosis cells with ECM can be postulated. Two systems of secreted proteases in the endometrium, the plasmin(ogen) activator/inhibitor and the matrix metalloproteinases and their inhibitors were examined in cell cultures of uterine endometrial cells from women with and without endometriosis. Soluble urokinase receptor secretion is increased, and mRNA transcription of tissue inhibitor of metalloproteinases-2 (TIMP-2) is upregulated by progestin in endometriosis. These findings are compatible with an altered ECM turnover in the endometrium of these patients that may explain a higher invasive potential of retrogradely menstruated endometrial fragments.
