Pharmacol Rep 2024:10.1007/s43440-024-00625-1. [PMID: 39093549 DOI: 10.1007/s43440-024-00625-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/27/2024] [Revised: 07/03/2024] [Accepted: 07/04/2024] [Indexed: 08/04/2024]
Abstract
BACKGROUND Endometriosis is a female hormone-dependent gynecological disorder characterized by chronic inflammation. Therefore, the development of novel treatment strategies that can diminish the side effects of the long-term use of hormone-based drugs has been emphasized. S-Allyl-L-cysteine (SAC) is the major constituent of aged garlic extracts. Although the therapeutic effects resulting from the antioxidant properties of SAC have been extensively studied in inflammatory diseases, the therapeutic efficacy of SAC in endometriosis has not been described. In this study, we investigated the therapeutic potential of SAC for endometriosis using a mouse model. METHODS An endometriosis mouse model was surgically induced, and oral treatment with 30 mg/kg SAC was administered daily for 28 days. The development of endometriotic lesions was assessed by histological analysis, and the expression profiles of adhesion-, apoptosis-, and inflammation-related genes were evaluated by PCR. Flow cytometric analysis of mouse spleen was conducted to assess changes in lymphocyte subpopulations. RESULTS SAC treatment significantly inhibited endometriotic lesion growth. Transcriptional expression analysis revealed the antiadhesion and apoptosis-promoting effects of SAC. In particular, SAC showed an effective immune modulatory response by altering splenic CD4+ and CD8+ T cell subsets and inflammatory cytokine production in the spleen and endometriotic lesions. CONCLUSION This study newly elucidates the inhibitory effects of SAC on the growth of endometriosis in a mouse model and describes its immunomodulatory effects.

Abstract
Endometriosis is a disease characterized by the implantation of endometrial-like tissue outside the uterine cavity. Common symptoms include cyclical pain, dysmenorrhea, dyspareunia, and infertility. Although endometriosis can spread to various extrauterine locations including the ovaries, fallopian tubes, and peritoneal surfaces, umbilical endometriosis is a rare manifestation of the disease. We report an intriguing clinical case of primary umbilical endometriosis in a 36-year-old female patient admitted to our department due to the notable manifestation of a painful swelling at the umbilicus, accompanied by cyclic episodes of bleeding. Subsequent investigations, incorporating ultrasound and computed tomography, indicated the presence of umbilical endometriosis, a finding that was subsequently confirmed by pathological examination of a mass biopsy. Surgical resection of the umbilical mass was performed, and histopathological analysis definitively confirmed the diagnosis of endometriosis. This case report aims to discuss in depth the diagnosis and management of umbilical endometriosis.

Abstract
Background Endometriosis is defined as a condition in which a formation of abnormal endometrial tissue outside the uterus takes place. Irrespective of any ethnic and socioeconomic class, the prevalence of the diseases has been seen among women of reproductive age. Endometriosis has been seen adversely affect the physical, psychological, social, and career of women. Summary This paper aims to identify and describe the experiences and outcomes of endometriosis healthcare by reviewing the existing literature on social and psychological effects of endometriosis. The study serves the purpose of providing insights on women's dual suffering (mental and social health) and critical comments on the present state of knowledge in order to make future recommendations for psycho-social research. The review included systematic search of the articles from various disciplines like, biology, psychology, sociology, anthropology, etc. A structured process of screening with specific inclusion and exclusion criteria was used to select the articles. The analysis of the articles resulted that woman diagnosed with endometriosis reported poor quality of life and the following symptoms such as anxiety, stress, Chronic Pelvic Pain (CPP), anxiety, dyspareunia, and dysmenorrhea. However, depression appears prominent among women diagnosed with endometriosis. There are few strategies mentioned that can be used to deal with endometriosis. Key Message The most promising causes of endometriosis include abnormality in immune functioning, atypical endometriotic growth, genetics, epigenetic, embryogenetic theory, and endocrine disruptors. The ill effects have been noted in the following domains of women's life such as work, close relationships, social well-being, and education, deteriorating their quality-of-life manifold. Psychological intervention is required to deal with the disorder as only medical treatment with pain may not be sufficient. Though, the condition can be improved by providing awareness regarding the severity of the disorder at the school and community levels.

Front Nutr 2023; 10:1089891. [PMID: 36875844 PMCID: PMC9983692 DOI: 10.3389/fnut.2023.1089891] [Citation(s) in RCA: 6] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/04/2022] [Accepted: 01/31/2023] [Indexed: 02/19/2023] Open
Abstract
Endometriosis is characterized by the presence of endometrial tissues outside the uterine lining, typically on the external surface of the uterus, the ovaries, fallopian tubes, abdominal wall, or intestines. The prevalence of endometriosis in North America, Australia, and Europe is ~1-5% in women of reproductive age. Treatment options for endometriosis are limited. While over-the-counter medications may be used to reduce acute pain, hormonal treatments are common and may interfere with fertility. In more severe cases, laparoscopic excision procedures and even hysterectomies are used to treat the pain associated with endometriosis. Nutritional interventions may be helpful in the prevention and treatment of endometriosis and associated pain. Reducing dietary fat and increasing dietary fiber have been shown to reduce circulating estrogen concentrations, suggesting a potential benefit for individuals with endometriosis, as it is an estrogen-dependent disease. Meat consumption is associated with greater risk of developing endometriosis. Anti-inflammatory properties of plant-based diets may benefit women with endometriosis. Additionally, seaweed holds estrogen-modulating properties that have benefitted postmenopausal women and offers potential to reduce estradiol concentrations in pre-menopausal women. Furthermore, consumption of vitamin D has been shown to reduce endometrial pain via increased antioxidant capacity and supplementation with vitamins C and E significantly reduced endometriosis symptoms, compared with placebo. More randomized clinical trials are needed to elucidate the role of diet in endometriosis.

Abstract
Endometriosis is a chronic systemic disease that can cause pain, infertility and reduced quality of life. Diagnosing endometriosis remains challenging, which yields diagnostic delays for patients. Research on diagnostic test accuracy in endometriosis can be difficult due to verification bias, as not all patients with endometriosis undergo definitive diagnostic testing. The purpose of this State-of-the-Art Review is to provide a comprehensive update on the strengths and limitations of the diagnostic modalities used in endometriosis and discuss the relevance of diagnostic test accuracy research pertaining to each. We performed a comprehensive literature review of the following methods: clinical assessment including history and physical examination, biomarkers, diagnostic imaging, surgical diagnosis and histopathology. Our review suggests that, although non-invasive diagnostic methods, such as clinical assessment, ultrasound and magnetic resonance imaging, do not yet qualify formally as replacement tests for surgery in diagnosing all subtypes of endometriosis, they are likely to be appropriate for advanced stages of endometriosis. We also demonstrate in our review that all methods have strengths and limitations, leading to our conclusion that there should not be a single gold-standard diagnostic method for endometriosis, but rather, multiple accepted diagnostic methods appropriate for different circumstances. © 2022 International Society of Ultrasound in Obstetrics and Gynecology.

[PMID: 35238789 PMCID: PMC8931644 DOI: 10.2196/31317] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/18/2021] [Revised: 10/18/2021] [Accepted: 11/06/2021] [Indexed: 12/01/2022] Open
Abstract
Background Endometriosis is a chronic condition that affects approximately 10% of women worldwide. Despite its wide prevalence, knowledge of endometriosis symptoms, such as pelvic pain, and treatments remains relatively low. This not only leads to a trivialization of symptoms and delayed diagnosis but also fuels myths and misconceptions about pain symptoms. At the same time, the use of web-based platforms for information seeking is particularly common among people with conditions that are perceived as stigmatizing and difficult to discuss. The Sex, Pain, and Endometriosis website is an educational resource designed to provide evidence-based information on endometriosis and sexual pain to help people understand the condition, feel empowered, dispel myths, and destigmatize endometriosis-associated sexual pain. Objective The study objective is to evaluate the usability of the website and assess for destigmatizing properties of sexual health–related web-based resources. Methods We conducted a usability analysis by using a think-aloud observation, a postsystem usability questionnaire, and follow-up interviews with 12 women with endometriosis. The think-aloud data were analyzed using the framework by Kushniruk and Patel for analyzing usability video data, the questionnaire data were analyzed using descriptive statistics, and the follow-up interviews were analyzed using simple content analysis. We conducted a usability assessment by deductively analyzing the interview data via a trauma-informed care framework and a content analysis approach. Results Through usability analysis, we found the website to be simple, uncluttered, satisfying, and easy to use. However, 30 minor usability problems related to navigation; website response; the comprehension of graphics, icons, and tabs; the understanding of content; and mismatch between the website and users’ expectations were reported. In our stigma analysis, we found the web content to be nonstigmatizing. The participants suggested ways in which websites could be designed to address stigma, including ensuring privacy, anonymity, inclusiveness, and factual and nonjudgmental content, as well as providing opportunities for web-based engagement. Conclusions Overall, the participants found the website to be useful, easy to use, and satisfying. The usability problems identified were largely minor and informed the website redesign process. In the context of the limited literature on stigma and website design, this paper offers useful strategies on how sexual health–related websites can be designed to be acceptable and less stigmatizing to individuals with sensitive health issues.

Abstract
Endometriosis is a common condition with significant morbidity. There have been case reports of endometrial deposits affecting the sciatic nerve. Sciatic nerve endometriosis presents with cyclical sciatica and is often difficult to diagnose as it mimics many other causes of sciatica. We report the first case of histological proven endometrial carcinoma arising in a pre-existing sciatic nerve endometriosis. This was initially managed with radiotherapy however symptoms persisted and she opted to have surgery with the aim of better symptom control and long-term prognosis.

Abstract
OBJECTIVE This study aimed to evaluate the validity of laparoscopic visualization for the diagnosis of endometriosis compared with histopathology. METHODS We conducted a retrospective chart review at a tertiary care hospital in Canada for the period of April 1, 2016 to March 31, 2017. Of 1069 women, 96 were selected for having undergone laparoscopic visualization and concurrent histopathological biopsy for suspected endometriosis. Standard measures of validity for diagnostic tests (sensitivity, specificity, positive predictive and negative predictive values, accuracy) were used. RESULTS Mean age of the 96 women included was 40 ± 7.2 years, and median gravidity and parity were 1 (IQR 0-3) and 0 (IQR 0-2), respectively. Common symptoms were abdominal and pelvic pain (41.7%), menstrual bleeding concerns (34.4%), dysmenorrhea (29.2%), and infertility (8.3%). Approximately one-third of women had endometriomas (31.3%), while more than half had deep infiltrating endometriosis (59.4%). The diagnosis of endometriosis was made by surgeons at laparoscopic visualization in 82.3% of women and by histopathology in 74.0%. Using histopathology as the gold standard, sensitivity for laparoscopic visualization was 90.1% (95% CI 81.0-95.1), while specificity was 40.0% (95% CI 23.4-59.3). Positive and negative predictive values were 81.0% (95% CI 71.0-88.1) and 58.8% (95% CI 36.0-78.4), respectively; and the accuracy was 77.1% (95% CI 67.7-84.4). CONCLUSION Although laparoscopic visualization had relatively high sensitivity and positive predictive value, its specificity and negative predictive value were relatively low. These findings support the use of laparoscopic visualization with histopathological analysis for accurate diagnosis of endometriosis.

Abstract
OBJECTIVE To assess the general population's knowledge regarding the utility and availability of tools to diagnosis endometriosis, with a focus on ultrasound. DESIGN An international cross-sectional online survey study was performed between August and October 2019. SETTING AND POPULATION 5301 respondents, representing 73 countries. METHODS In all, 23 questions survey focused on knowledge of endometriosis diagnosis distributed globally via patient- and community-endometriosis groups using social media. MAIN OUTCOMES AND MEASURES Descriptive data of the knowledge of diagnostic tools for diagnosing endometriosis, including details about diagnosis using ultrasound. RESULTS In all, 84.0% of respondents had been previously diagnosed with endometriosis, 71.5% of whom had been diagnosed at the time of surgery. Ultrasound and MRI were the methods of diagnosis in 6.5% and 1.8%, respectively. A total of 91.8%, 28.8% and 16.6% of respondents believed surgery, ultrasound and MRI could diagnose endometriosis, respectively (more than one answer allowed). In those diagnosed by surgery, 21.7% knew about ultrasound as a diagnosis method, whereas in those diagnosed non-surgically, 51.5% knew (P < 0.001).
