Uterine fibroid

子宫肌瘤
  • 文章类型: Case Reports
    子宫平滑肌瘤(ULs)是常见的良性肿瘤,在很大一部分女性中可以根据其在子宫内的位置进行分类。它们可以引起许多骨盆并发症,并且可以进行医学管理,但更常见的是手术。子宫肌瘤常发生在产后,可能是梗塞,并可能导致变性和败血症。我们的病人出现了两个月的潜在化脓性肌瘤,最初在计算机断层扫描(CT)上发现。办公室检查显示子宫颈有突出的肿块,并尝试切除,但最终因疼痛而推迟进行全身麻醉检查。切除平滑肌瘤并显示坏死。化脓性肌瘤通常是阴险的,并且通常可以模仿其他有关的病理。现代成像可以显示骨盆内的病变,但难以在液体收集和可能的梗塞肿块之间进行确定。在这种情况下,质量护理措施的重要性值得强调,以防止严重的并发症。
    Uterine leiomyomas (ULs) are common benign tumors seen in a large percent of women that can be classified based on their location within the uterus. They can cause a number of pelvic complications and can be managed medically, but more often surgically. Uterine pyomyomas often occur postpartum, possibly from infarction, and can lead to degeneration and sepsis. Our patient presents with a two-month development of a potential pyomyoma, found initially on computed tomography (CT). Office exam reveals a protruding mass from the cervical os, and removal was attempted but ultimately postponed for general anesthesia exam due to pain. The leiomyoma was removed and shown to be necrosing. Pyomyomas are often insidious and can often mimic other concerning pathologies. Modern imaging can show lesions within the pelvis but struggle to determine between fluid collection and possible infarcted masses. The importance of quality care measures in cases like this deserve to be emphasized to prevent serious complications.

    目的:子宫肌瘤增加早产风险。目前的研究强调子宫肌瘤坏死是(极端)早产的可能原因。
    方法:在一家荷兰学术医院进行回顾性队列研究。病例是从MyoFert研究的526名参与者中选出的(荷兰试验登记册,NL7990),其中包括2004年至2018年期间就诊的患者,诊断为子宫肌瘤时年龄在18岁至45岁之间.在这些参与者中,414名妇女怀孕了。对首次妊娠进行了回顾性图表回顾。主要结果是(即将发生的)早产和超声检查显示的纤维瘤坏死迹象。在有纤维样坏死迹象的女性中,系统地收集了以下数据:纤维瘤特征,临床表现,妊娠结局,和产后。
    结果:总计,66名妇女早产(16%,66/414),其中25例怀孕在16到<24周之间结束(38%,25/66)和41例怀孕在妊娠24至<37周之间结束(62%,41/66)。在所有早产和可用超声图像的妇女中,15%(7/48)在分娩时出现纤维样坏死。这七个病人,补充了三名在第一次怀孕期间患有纤维瘤坏死的患者和至少一次即将发生早产的患者,更详细地描述了。在这十位患者中,在妊娠早期和中期,肌瘤的大小显著增加,导致所有患者严重腹痛,7例患者入院。超声检查显示肌瘤异源性改变和局灶性跨音速区,这是表明纤维瘤坏死的特征。在四名患者中,行子宫肌瘤切除术,组织学证实坏死。
    结论:妊娠期间的纤维样坏死可能与(即将发生的)早产有关。建议临床医生在结构上评估妊娠子宫肌层,特别是在妊娠中期出现腹痛的女性中。
    OBJECTIVE: Uterine fibroids increase the risk of preterm birth. The current study highlights uterine fibroid necrosis as a possible cause of (extreme) preterm birth.
    METHODS: Retrospective cohort study in one Dutch academic hospital. Cases were selected from the 526 participants of the MyoFert study (Netherlands Trial Register, NL7990), which included patients who presented between 2004 and 2018 and were between the age of 18 and 45 years at the time of diagnosis of uterine fibroids. Of these participants, 414 women became pregnant. A retrospective chart review of the first pregnancies was performed. The main outcomes were (imminent) preterm birth and signs of fibroid necrosis on ultrasound. In women with signs of fibroid necrosis, the following data were collected systematically: fibroid characteristics, clinical presentation, pregnancy outcome, and postpartum period.
    RESULTS: In total, 66 women had a preterm birth (16 %, 66/414), of which 25 pregnancies ended between 16 and <24 weeks (38 %, 25/66) and 41 pregnancies ended between 24 and <37 weeks of gestation (62 %, 41/66). Of all women with preterm birth and available ultrasound images, 15 % (7/48) had fibroid necrosis at the time of labour. These seven patients, supplemented with three patients with fibroid necrosis during their first pregnancy and at least one episode of imminent preterm birth, are described in more detail. In these ten patients, the fibroids increased substantially in size during the first and second trimester, leading to severe abdominal pain in all patients and hospital admission in seven patients. Ultrasound examination of the fibroids showed heterogenic changes and focal transonic areas in the fibroid, which are characteristics that indicate fibroid necrosis. In four patients, myomectomy was performed and necrosis was confirmed histologically.
    CONCLUSIONS: Fibroid necrosis during pregnancy is likely associated with (imminent) preterm birth. Clinicians are advised to structurally evaluate the myometrium in pregnancy, specifically in women presenting with abdominal pain in the second trimester.

    该病例报告显示了一对夫妇原发性不孕症的治疗方法:男性37岁,女性32岁。女性患有粘膜下子宫肌瘤。稍后,在两个宫腔内人工授精(IUI)周期失败后,该女性行子宫肌瘤切除术,以切除子宫粘膜下肌瘤.经过六个月的恢复期,她接受了体外受精(IVF)周期的卵子拾取。在卵子拾取(OPU)的过程中,回收了四个卵母细胞:三个在中期一(M1)阶段,一个在中期二(M2)阶段。随后,这对夫妇经历了卵母细胞的体外成熟(IVM),其中M1期卵母细胞培养6小时。M1期卵母细胞进展到M2期。然后给这些卵母细胞注射精子,这导致了两个胚泡的形成。然后将这些胚泡冷冻保存三个月,三个月后,然后转移这些冷冻胚胎,导致成功的概念。该案例研究评估了一对患有不孕症的夫妇。这项研究包括子宫肌瘤切除术和体外成熟的治疗。
    This case report demonstrates the management of primary infertility in a couple: the male was 37 years old and the female was 32 years old. The female had a submucosal uterine fibroid. Later, the female underwent a myomectomy to remove submucosal fibroids in the uterus after two failed intrauterine insemination (IUI) cycles. After six months of her recovery period, she underwent ovum pickup for an in vitro fertilization (IVF) cycle. During the process of ovum pickup (OPU), four oocytes were retrieved: three in the metaphase one (M1) stage and one in the metaphase two (M2) stage. Subsequently, the couple underwent in vitro maturation (IVM) of oocytes, where the M1 stage oocytes were cultured for six hours. The M1 stage oocytes progressed to the M2 stage. These oocytes were then injected with sperm, which resulted in the formation of two blastocysts. These blastocysts were then cryopreserved for three months, and after three months, these frozen embryos were then transferred, leading to the successful conception. The case study evaluates a couple who suffered from infertility. This study includes a treatment of myomectomy and in vitro maturation.

    背景/目的:经宫颈肌瘤消融术(TFA)是一种无切口治疗有症状子宫肌瘤的方法。虽然未来怀孕的安全性仍有待确定,TFA并不排除怀孕的可能性,先前36例患者的TFA后妊娠病例报告结果正常。之前的系列不包括美国的上市后案例,索纳塔®系统最初在欧洲被清除和使用。这是自2011年6月以来使用奏鸣曲系统的已知怀孕情况的实质性更新,包括欧洲的怀孕情况,墨西哥,和美国。方法:在临床试验和上市后使用TFA治疗有症状的子宫肌瘤。包括医生在患者同意的情况下报告的所有TFA后怀孕。结果:在接受奏鸣曲系统治疗的72名妇女中,有89例怀孕和55例分娩。这包括8名妇女在TFA后怀孕不止一次。完成妊娠(n=62名妇女)包括19例阴道分娩,35剖腹产,5例治疗性流产,1异位妊娠,和1个未知路线的交付。十次怀孕正在进行中。平均出生体重为3276.7±587.3g。10名妇女经历了18次妊娠早期自然流产(SABS),18例SAb中有10例(55.6%)发生在有复发性流产史的两名患者之间。SAb率为22.8%,包括这两个病人,如果将它们排除为异常值,则为10.1%。没有子宫破裂,胎盘植入光谱,或者死产.结论:这个案例系列,迄今为止最大的高温消融模式,这表明索纳塔系统的TFA可能是可行的,关于有症状的子宫肌瘤妇女最终妊娠的安全治疗选择.
    Background/Objectives: Transcervical fibroid ablation (TFA) is an incisionless method to treat symptomatic uterine fibroids. While safety regarding future pregnancy remains to be established, TFA does not preclude the possibility of pregnancy, and a previous 36-patient case series of post-TFA pregnancies reported normal outcomes. That prior series did not include postmarket cases in the United States, as the Sonata® System was initially cleared and used in Europe. This is a substantive update of known pregnancies with the Sonata System since June 2011, and includes pregnancies in Europe, Mexico, and the US. Methods: TFA was carried out under both clinical trial and postmarket use to treat symptomatic uterine fibroids. All post-TFA pregnancies reported by physicians with their patient\'s consent were included. Results: 89 pregnancies and 55 deliveries have occurred among 72 women treated with the Sonata System. This includes 8 women who conceived more than once after TFA. Completed pregnancies (n = 62 women) include 19 vaginal deliveries, 35 Cesarean sections, 5 therapeutic abortions, 1 ectopic pregnancy, and 1 delivery by an unknown route. Ten pregnancies are ongoing. Mean birthweight was 3276.7 ± 587.3 g. Ten women experienced 18 first-trimester spontaneous abortions (SAbs), with 10 of the 18 SAbs (55.6%) occurring between two patients with a history of recurrent abortion. The SAb rate was 22.8%, inclusive of these two patients, and 10.1% if they were excluded as outliers. There were no instances of uterine rupture, placenta accreta spectrum, or stillbirth. Conclusions: This case series, the largest to date for any hyperthermic ablation modality, suggests that TFA with the Sonata System could be a feasible, safe treatment option regarding eventual pregnancy in women with symptomatic uterine fibroids.

    目的:子宫肌瘤(UF)是女性最常见的肿瘤,对并发症构成巨大威胁,比如流产。预后的准确性也可能受到医生经验不足和疲劳的影响,强调需要自动分类的方式,可以分析UF从一个巨大的各种各样的图像。
    方法:已经提出了一种混合模型,该模型将MobileNetV2社区和深度卷积生成对抗网络(DCGAN)结合为医疗从业者找出UF并评估其特征的有用资源。UF的实时自动分类可以帮助诊断情况并最大程度地减少主观错误。DCGAN科学用于卓越的统计增强,以创建一流的UF图像,将其标记为UF和非子宫肌瘤(NUF)类别。然后,MobileNetV2模型完全基于此数据对照片进行精确分类。
    结果:混合模型的整体性能与不同模型形成对比。混合模型实现了40帧每秒(FPS)的实时分类速度,准确率为97.45%,F1等级为0.9741。
    结论:通过使用这种深度学习混合方法,针对目前子宫肌瘤分类方法的不足。
    OBJECTIVE: Uterine fibroids (UF) are the most frequent tumors in ladies and can pose an enormous threat to complications, such as miscarriage. The accuracy of prognosis may also be affected by way of doctor inexperience and fatigue, underscoring the want for automatic classification fashions that can analyze UF from a giant wide variety of images.
    METHODS: A hybrid model has been proposed that combines the MobileNetV2 community and deep convolutional generative adversarial networks (DCGAN) into useful resources for medical practitioners in figuring out UF and evaluating its characteristics. Real-time automated classification of UF can aid in diagnosing the circumstance and minimizing subjective errors. The DCGAN science is utilized for superior statistics augmentation to create first-rate UF images, which are labeled into UF and non-uterine-fibroid (NUF) classes. The MobileNetV2 model then precisely classifies the photos based totally on this data.
    RESULTS: The overall performance of the hybrid model contrasts with different models. The hybrid model achieves a real-time classification velocity of 40 frames per second (FPS), an accuracy of 97.45%, and an F1 rating of 0.9741.
    CONCLUSIONS: By using this deep learning hybrid approach, we address the shortcomings of the current classification methods of uterine fibroid.

    这两例病例的报告长期认为镰状细胞特征(SCT)是临床上的良性疾病,突出了其复杂而严重的临床表现,特别是在失血性贫血和血管闭塞危象(VOCs)的情况下。镰状细胞疾病的标志是由微血管系统的急性血管闭塞引起的严重疼痛,导致骨髓梗塞。我们报告了两例SCT和严重贫血的患者,这些患者继发于子宫肌瘤的失血,随后导致VOC并可能发生骨隔离。SCT中VOCs的发生,虽然不常见,可能很严重,需要很高的怀疑指数,特别是当患者出现严重的痛苦和排除心脏或血管病因时。在这种情况下,贫血的逆转提供了快速解决的症状,我们建议其他临床医生不要忽视SCT携带者中VOC的差异,并敦促治疗患者,就像他们患有镰状细胞疾病一样。本报告挑战SCT作为临床良性条件的传统观点,呼吁重新校准临床理解,管理策略,并在类似情况下关注这种遗传性状。
    This report of two cases confronts the longstanding perception of Sickle Cell Trait (SCT) as a clinically benign condition, highlighting its complex and severe clinical manifestations, particularly in the context of blood loss anemia and vaso-occlusive crises (VOCs). The hallmark of sickle cell disease is the severe pain caused by acute vaso-occlusion of the microvasculature that leads to bone marrow infarction. We report two cases of patients with SCT and severe anemia in the setting of blood loss secondary to uterine fibroids subsequently causing VOCs with likely bone sequestration. The occurrence of VOCs in SCT, while infrequent, can be serious and demands a high index of suspicion, particularly when patients appear in significant distress and cardiac or vascular etiologies are ruled out as a source. Reversal of anemia in this case provided quick resolution to symptoms, and we recommend other clinicians not disregard a differential of VOC in SCT carriers, and urge to treat patients as they would if they had sickle cell disease. This report challenges the conventional view of SCT as a condition of clinical benignity, calling for a recalibration in the clinical understanding, management strategies, and focus on this genetic trait under similar circumstances.

    目的:Raf激酶抑制蛋白(RKIP)在平滑肌瘤不同亚型中的表达模式如何(普通型,细胞,中风或出血性平滑肌瘤,具有奇异核的平滑肌瘤和脂肪平滑肌瘤)和平滑肌肉瘤标本,
    方法:对平滑肌瘤和平滑肌肉瘤标本进行免疫组化染色。平滑肌肉瘤SK-LMS-1细胞系被RKIP敲除,RKIP过表达,和细胞活力,进行了伤口愈合迁移和克隆形成试验。
    结果:在奇异平滑肌瘤中观察到较高的RKIP免疫组织化学表达,比普通型平滑肌瘤。在细胞平滑肌瘤中也发现表达降低,在平滑肌肉瘤中通常没有染色。在SK-LMS-1细胞系中进行RKIP表达操作后,随着时间的推移,细胞活力和迁移能力没有观察到重大差异。RKIP淘汰赛,然而,导致细胞形成集落的能力显着增加(P=0.011)。
    结论:RKIP在平滑肌瘤组织型和平滑肌肉瘤中不同的表达模式,以及它对平滑肌肉瘤细胞集落形成的影响,鼓励RKIP在子宫平滑肌疾病中的进一步研究。
    OBJECTIVE: What is the expression pattern of Raf kinase inhibitory protein (RKIP) in different subtypes of leiomyoma (usual type, cellular, apoplectic or haemorrhagic leiomyoma, leiomyoma with bizarre nuclei and lipoleiomyoma) and leiomyosarcoma specimens, and what is its biological role in leiomyosarcoma cells?
    METHODS: Leiomyoma and leiomyosarcoma specimens underwent immunohistochemistry staining. Leiomyosarcoma SK-LMS-1 cell line was RKIP knocked down and RKIP overexpressed, and cell viability, wound healing migration and clonogenicity assays were carried out.
    RESULTS: A higher immunohistochemical expression of RKIP was observed in bizarre leiomyomas, than in usual-type leiomyomas. Decreased expression was also found in cellular leiomyoma, with generally absent staining in leiomyosarcomas. Upon RKIP expression manipulation in SK-LMS-1 cell line, no major differences were observed in cell viability and migration capacity over time. RKIP knockout, however, resulted in a significant increase in the cell\'s ability to form colonies (P = 0.011).
    CONCLUSIONS: RKIP distinct expression pattern among leiomyoma histotype and leiomyosarcoma, and its effect on leiomyosarcoma cells on colony formation, encourages further studies of RKIP in uterine smooth muscle disorders.

    子宫肌瘤是最常见的非癌性肿瘤,长期药物治疗没有令人满意的选择。成纤维细胞活化蛋白-α(FAP)是增强子宫肌瘤纤维化的关键酶之一。通过STITCH数据库挖掘,我们发现二肽基肽酶-4抑制剂(DPP4i)具有抑制FAP活性的潜力。DPP4和FAP都属于二肽基肽酶家族并且共享相似的催化结构域。因此,与DPP4具有结合亲和力的配体也可以与FAP结合。在DPP4i中,利格列汀与FAP的结合亲和力最高(Dock评分=-8.562kcal/mol)。我们的研究发现,DPP4和FAP之间S2广泛亚位点残基的差异可以作为设计特异性靶向FAP的选择性抑制剂的基础。此外,在动态环境中,利拉列汀能够破坏FAP的二聚化界面,导致其生物活性的潜在抑制。忠实于计算机结果,利格列汀可减少雌激素和孕激素诱导的大鼠子宫纤维化过程。此外,利格列汀降低转化生长因子-β(TGF-β)的基因表达,胶原蛋白分泌和纤维化过程中的一个关键因素。Masson三色染色证实,利格列汀的抗纤维化作用是由于其减少大鼠子宫中胶原蛋白沉积的能力。总之,我们的研究表明,利格列汀有可能用于子宫肌瘤的治疗.
    Uterine fibroid is the most common non-cancerous tumor with no satisfactory options for long-term pharmacological treatment. Fibroblast activation protein-α (FAP) is one of the critical enzymes that enhances the fibrosis in uterine fibroids. Through STITCH database mining, we found that dipeptidyl peptidase-4 inhibitors (DPP4i) have the potential to inhibit the activity of FAP. Both DPP4 and FAP belong to the dipeptidyl peptidase family and share a similar catalytic domain. Hence, ligands which have a binding affinity with DPP4 could also bind with FAP. Among the DPP4i, linagliptin exhibited the highest binding affinity (Dock score = -8.562 kcal/mol) with FAP. Our study uncovered that the differences in the S2 extensive-subsite residues between DPP4 and FAP could serve as a basis for designing selective inhibitors specifically targeting FAP. Furthermore, in a dynamic environment, linagliptin was able to destabilize the dimerization interface of FAP, resulting in potential inhibition of its biological activity. True to the in-silico results, linagliptin reduced the fibrotic process in estrogen and progesterone-induced fibrosis in rat uterus. Furthermore, linagliptin reduced the gene expression of transforming growth factor-β (TGF-β), a critical factor in collagen secretion and fibrotic process. Masson trichrome staining confirmed that the anti-fibrotic effects of linagliptin were due to its ability to reduce collagen deposition in rat uterus. Altogether, our research proposes that linagliptin has the potential to be repurposed for the treatment of uterine fibroids.

    目的:子宫肌瘤是激素依赖性子宫肿瘤。关于肥胖和肌瘤患病率的文献不一致。以前的工作通常将所有体重指数(BMIs)≥30kg/m2的人合并为一个类别,并依赖于临床诊断的肌瘤,这些肌瘤错误地将许多未确诊的肌瘤妇女分类。我们使用前瞻性队列设计与定期超声筛查,以调查BMI的重复测量与每次随访超声评估的肌瘤发生率和生长之间的关联。
    方法:环境研究,生活方式和纤维(SELF)跟随1,693名黑人/非裔美国女性,来自底特律的23-35岁,密歇根州每20个月进行一次超声检查,持续5年。测量的身高和重复的体重测量用于计算BMI。在注册超声检查中无纤维瘤的患者中,使用Cox模型对纤维瘤发生率进行建模。估计在每次就诊之间匹配的个体肌瘤的纤维瘤生长作为就诊之间的对数体积差异,并使用线性混合模型进行建模。所有模型均使用随时间变化的BMI,并针对随时间变化的协变量进行了调整。
    结果:与BMI<25kg/m2相比,BMI为30-<35kg/m2的患者的肌瘤发病率增加(调整后的危险比(aHR)1.37,(95%置信区间(CI):0.96-1.94)),BMI≥40kg/m2的患者的发病率降低(aHR0.61,(95%CI:0.41~0.90)).纤维生长与BMI之间的关联大多很小。
    结论:BMI与纤维瘤发病率存在非线性关联,这可能是由BMI对炎症和生殖激素的影响所驱动。内脏和皮下脂肪及其对激素的影响的更详细的措施,DNA损伤,需要细胞死亡。
    OBJECTIVE: Fibroids are hormonally dependent uterine tumors. The literature on adiposity and fibroid prevalence is inconsistent. Previous work usually combined all those with body mass indexes (BMIs) ≥30kg/m2 into a single category and relied on clinically diagnosed fibroids which misclassifies the many women with undiagnosed fibroids. We used a prospective cohort design with periodic ultrasound screening to investigate associations between repeated measures of BMI and fibroid incidence and growth assessed at each follow-up ultrasound.
    METHODS: The Study of Environment, Lifestyle & Fibroids (SELF) followed 1,693 Black/African American women, ages 23-35 from Detroit, Michigan with ultrasound every 20 months for 5 years. Measured height and repeated weight measures were used to calculate BMI. Fibroid incidence was modeled using Cox models among those who were fibroid-free at the enrollment ultrasound. Fibroid growth was estimated for individual fibroids matched across visits as the difference in log-volume between visits and was modeled using linear mixed models. All models used time-varying BMI and adjusted for time-varying covariates.
    RESULTS: Compared to BMI <25kg/m2 those with BMI 30-<35kg/m2 had increased fibroid incidence (adjusted hazard ratio (aHR) 1.37, (95% Confidence Interval (CI): 0.96-1.94)), those with BMI ≥40kg/m2 had reduced incidence (aHR 0.61, (95% CI: 0.41-0.90)). Fibroid growth had mostly small magnitude associations with BMI.
    CONCLUSIONS: BMI has a non-linear association with fibroid incidence that could be driven by effects of BMI on inflammation and reproductive hormones. More detailed measures of visceral and subcutaneous adiposity and their effects on hormones, DNA damage, and cell death are needed.
