The objective of this case series is to report clinical presentation, diagnosis, and management of various forms of cutaneous endometriosis. Material and Methods: It was an observational, retrospective and descriptive review of cases presenting with cutaneous endometriosis among Cameroonian women managed at the gynaecological outpatient department of Yaounde Gynaeco-Obstetric and Pediatric Hospital. All the following parameters were analysed: age, parity, previous pelvic surgery, presenting symptoms and duration, associated symptoms, localizations, imaging, size of the lesion, other localization of endometriosis, management and histopathological results. Results: we reported 4 cases of cutaneous endometriosis, with 3 umbilical endometriosis and 1 abdominal scar endometriosis. Patient age ranged from 28 to 39 years with an average of 33 years. All patients described infertility (two primary and two secondary) and two had a history of abdominal surgery. All patients presented local cyclical signs such as pain, swelling, color change and bleeding. The duration of symptoms varied from 2 to 3 years and the size of lesions ranged from 2 to 3.5 cm for umbilical lesions and was 9 cm for abdominal scar endometriosis. In all cases, no imaging was required for the diagnosis, which was suspected on the basis of patient’s history and the cyclical nature of local signs, followed by wide surgical excision and confirmation on histopathology. Conclusion: Cutaneaous endometriosis is a rare benign condition. Umbilical endometriosis seems to be the main cutaneous localization and can be described as primary or secondary. Even if its diagnosis must be confirmed by histopathology, it should be considered in patient with cutaneous cyclic signs such as pain, swelling or bleeding with or without history of abdominal surgery.展开更多

It is estimated that 6% to 10% of women of reproductive age, 50% to 60% of adolescents and adults with pelvic pain, and up to 50% of women with infertility are pregnant from the condition. However, this proportion tends to be even greater due to the difficulty in diagnosing it: because it presents different symptoms, lack of information from health professionals, and a high-cost diagnostic test. Another aggravating factor is the average time from the onset of symptoms to the medical diagnosis, which even today ranges from five to ten years;this delay has consequences for disease progression, as it prevents early treatment, which is important for improving pain levels and physical and psychological well-being. Aware of these mishaps, it is therefore important to assess the difficulties faced by doctors in the diagnosis of endometriosis in the public health system, in Brazil, the Unified Health System (SUS). With this purpose, a cross sectional was carried out, developed in the virtual environment using traffic in Google forms, with the difficulties quantified in the Likert scale. Participating physicians pointed out a medium difficulty for patients with endometriosis to access the consultation (58%) and moderate difficulty (52%) to perform an ultrasound examination;also signaled great difficulty in performing magnetic resonance imaging (77%) and laparotomy (61%) in these patients. It is hoped that knowledge about the difficulties faced by physicians in the diagnosis of endometriosis in the SUS will give these physicians a voice and corroborate, even if minimally, so that there is more research that provokes the search for these difficulties, in order to improving the quality of life of these women.展开更多

Our aim was to describe the epidemiological profile, clinical presentation and location of lesions in patients operated on for endometriosis. Methodology: We conducted an analytical cross-sectional study with retrospective data collection over a period of 05 years from 1 January 2017 to 31 March 2022. Our study population consisted of women who had undergone laparoscopy for endometriosis. Data analysis was performed using SPSS software version 23.0. Results: In total we included 159 patients who had undergone laparoscopy for endometriosis. The mean age was 32.9 ± 5.9 years, most of whom were nuligravida 61.6% (n = 99). Infertility was the most frequent reason for consultation, accounting for 72.3% (n = 115), followed by dysmenorrhoea in 60.8% (n = 96) of cases and chronic pelvic pain in 37.7% (n = 60). In addition, 46 (28.9%) patients complained of deep dyspareunia, 17 (10.7%) of dyschezia and nine (5.7%) of dysuria. Magnetic Resonance Imaging (MRI) was used in one patient. Diagnostic laparoscopy was performed directly in 77 (48.4%) patients. The lesions were multifocal, according to the #ENZIAN classification nomenclature. Tubal lesions were most frequently found 107 (67.3%) on the left, followed by compartment B (uterosacral ligaments, cardinal ligaments and lateral pelvic wall) 49.7% (n = 79), and endometriomas 40.9% (n = 65). Conclusion: Women operated on for endometriosis were of a more advanced age, and predominantly nulliparous. Infertility was the most frequent reason for consultation and tubal location most frequently encountered for superficial lesions and compartiment B for deep lesions according to #ENZIA.展开更多

文摘Endometriosis is a common chronic gynecological disease with endometrial cell implantation outside the uterus.Angiogenesis is a major pathophysiology in endometriosis.Our previous studies have demonstrated that the prodrug of epigallocatechin gallate(ProEGCG)exhibits superior anti-endometriotic and anti-angiogenic effects compared to epigallocatechin gallate(EGCG).However,their direct binding targets and underlying mechanisms for the differential effects remain unknown.In this study,we demonstrated that oral ProEGCG can be effective in preventing and treating endometriosis.Additionally,1D and 2D Proteome Integral Solubility Alteration assay-based chemical proteomics identified metadherin(MTDH)and PX domain containing serine/threonine kinase-like(PXK)as novel binding targets of EGCG and ProEGCG,respectively.Computational simulation and BioLayer interferometry were used to confirm their binding affinity.Our results showed that MTDH-EGCG inhibited protein kinase B(Akt)-mediated angiogenesis,while PXK-ProEGCG inhibited epidermal growth factor(EGF)-mediated angiogenesis via the EGF/hypoxia-inducible factor(HIF-1a)/vascular endothelial growth factor(VEGF)pathway.In vitro and in vivo knockdown assays and microvascular network imaging further confirmed the involvement of these signaling pathways.Moreover,our study demonstrated that ProEGCG has superior therapeutic effects than EGCG by targeting distinct signal transduction pathways and may act as a novel antiangiogenic therapy for endometriosis.
文摘Introduction: Cutaneous endometriosis is an uncommon but well-known skin disorder that represents about 0.5% to 1% of all endometriosis. The objective of this case series is to report clinical presentation, diagnosis, and management of various forms of cutaneous endometriosis. Material and Methods: It was an observational, retrospective and descriptive review of cases presenting with cutaneous endometriosis among Cameroonian women managed at the gynaecological outpatient department of Yaounde Gynaeco-Obstetric and Pediatric Hospital. All the following parameters were analysed: age, parity, previous pelvic surgery, presenting symptoms and duration, associated symptoms, localizations, imaging, size of the lesion, other localization of endometriosis, management and histopathological results. Results: we reported 4 cases of cutaneous endometriosis, with 3 umbilical endometriosis and 1 abdominal scar endometriosis. Patient age ranged from 28 to 39 years with an average of 33 years. All patients described infertility (two primary and two secondary) and two had a history of abdominal surgery. All patients presented local cyclical signs such as pain, swelling, color change and bleeding. The duration of symptoms varied from 2 to 3 years and the size of lesions ranged from 2 to 3.5 cm for umbilical lesions and was 9 cm for abdominal scar endometriosis. In all cases, no imaging was required for the diagnosis, which was suspected on the basis of patient’s history and the cyclical nature of local signs, followed by wide surgical excision and confirmation on histopathology. Conclusion: Cutaneaous endometriosis is a rare benign condition. Umbilical endometriosis seems to be the main cutaneous localization and can be described as primary or secondary. Even if its diagnosis must be confirmed by histopathology, it should be considered in patient with cutaneous cyclic signs such as pain, swelling or bleeding with or without history of abdominal surgery.

文摘Introduction: Endometriosis is a chronic disease affecting approximately 10% of women. Our aim was to describe the epidemiological profile, clinical presentation and location of lesions in patients operated on for endometriosis. Methodology: We conducted an analytical cross-sectional study with retrospective data collection over a period of 05 years from 1 January 2017 to 31 March 2022. Our study population consisted of women who had undergone laparoscopy for endometriosis. Data analysis was performed using SPSS software version 23.0. Results: In total we included 159 patients who had undergone laparoscopy for endometriosis. The mean age was 32.9 ± 5.9 years, most of whom were nuligravida 61.6% (n = 99).

文摘Background:Chinese herbal medicines have been proven to be effective in clinical treatment and disease prevention.Jinlingzi San is a herbal medicine used for the treatment of endometriosis.However,a comprehensive network pharmacology approach has not been used to understand the active ingredients and therapeutic mechanisms behind Jinlingzi San in the treatment of endometriosis.Methods:A network pharmacology approach and a molecular docking approach were used to predict the active ingredients and potential targets of Jinlingzi San in the treatment of endometriosis.Results:The integrated network pharmacology approach successfully identified 60 active ingredients and 540 key targets of action in Jinlingzi San dispersion.Among them,STAT3,TP53,MAPK3,RELA,MAPK1,JUN and other key genes were mainly regulated through pathways in cancer,lipid and atherosclerosis,AGE-RAGE signaling pathway in diabetic complications,pancreatic cancer,prostate cancer,PI3K-Akt signaling pathway,Th17 cell differentiation,and other signaling pathways in the cell body,receptor complexes,cytoplasm,nucleoplasm,and plasma membrane.Conclusion:Based on a systems network pharmacology approach,our work successfully predicts the active components and potential targets of Jinlingzi San for the treatment of endometriosis and helps to illustrate the mechanism of action at an integrative level.This demonstrates that Jinlingzi San for the treatment of endometriosis is regulated through a multi-component,multi-target,multi-system co-regulation.This study identifies key genes and pathways associated with endometriosis and pathogenesis from new insights,and also provides a viable approach to the chemical basis and pharmacological studies of Jinlingzi San.
文摘Deep infiltrating endometriosis is an often-painful disorder affecting women during their reproductive years that usually involves the structures of the pelvis and frequently the gastrointestinal tract.We present the case of a 37-year-old female patient with an endometrial growth on the sigmoid colon wall causing pain,diarrhea and the presence of blood in the feces.The histology of the removed specimen also revealed the involvement of the utero-vesical fold,the recto-vaginal septum and a pericolic lymph node,which are all quite uncommon findings.To identify the endometrial cells,we performed immunohistochemical staining for CD10and the estrogen and progesterone receptors.
文摘Bowel endometriosis affects between 3.8% and 37% of women with endometriosis.The evaluation of symptoms and clinical examination are inadequate for an accurate diagnosis of intestinal endometriosis.Transvaginal ultrasonography is the first line investigation in patients with suspected bowel endometriosis and allows accurate determination of the presence of the disease.Radiological techniques (such as magnetic resonance imaging and multidetector computerized tomography enteroclysis) are useful for estimating the extent of bowel endometriosis.Hormonal therapies (progestins,gonadotropin releasing hormone analogues and aromatase inhibitors) significantly improve pain and intestinal symptoms in patients with bowel stenosis less than 60% and who do not wish to conceive.However,hormonal therapies may not prevent the progression of bowel endometriosis and,therefore,patients receiving long-term treatment should be periodically monitored.Surgical excision of bowel endometriosis should be offered to symptomatic patients with bowel stenosis greater than 60%.Intestinal endometriotic nodules may be excised by nodulectomy or segmental resection.Both surgical procedures improve pain,intestinal symptoms and fertility.Nodulectomy may be associated with a lower rate of complications.
文摘目的·探讨基于EMS[环境管理(environment management,E)、用药指导(medicine direction,M)与自我监测(self monitoring,S)]管理模式的延续性护理在学龄前喘息性疾病儿童中的应用效果。方法·选取2019年12月至2020年11月,在上海交通大学医学院附属儿童医院呼吸科收治的67例0~6岁喘息性疾病患儿,按照随机数字表分为观察组33例和对照组34例,其中失访3例,最终每组32例。观察组采用基于EMS管理模式的延续性护理,对照组给予常规护理和出院电话随访。2组患儿出院后1、3、6个月随访评估儿童呼吸和哮喘测试(Test for Respiratory and Asthma Control in Kids,TRACK)结果、喘息复发情况;出院后6个月随访采用支气管哮喘用药依从性评分表(Medication Adherence Report Scale for Asthma,MARS-A)和护理工作满意度调查表评估用药依从性及护理工作满意度。结果·2组患儿人口学特征及临床基线特征差异无统计学意义。重复测量方差分析结果显示,时间、组别、组别×时间的交互作用对TRACK总分的影响均有统计学意义;出院后1、3、6个月,观察组TRACK总分均显著高于对照组(均P=0.000);2组患儿TRACK总分均随时间推移逐渐上升(P=0.000)。观察组1、3、6个月随访发现喘息复发率分别为25.0%、18.7%、9.4%,均显著低于对照组(分别为50.0%、43.7%、31.3%,均P<0.05);广义估计方程分析显示组间比较差异有统计学意义(P=0.013),观察组干预效果优于对照组(OR=0.292)。出院后6个月观察组MARS-A得分为(4.519±0.395)分,显著高于对照组[(3.994±0.739)分,P=0.001]。护理工作满意度调查结果显示,观察组显著高于对照组(P=0.000)。患儿MARS-A得分与护理工作满意度呈中度正相关(r=0.389,P=0.001)。结论·基于EMS管理模式的延续性护理可显著提高学龄前喘息性疾病儿童的用药依从性和喘息控制水平,明显降低喘息复发率,以及提高护理工作满意度。
