    记录妊娠18周零天至23周六天之间流产的门诊医疗管理的临床结果。
    我们对2017年10月至2021年11月在亚利桑那州一家诊所接受米非司酮和重复米索前列醇治疗妊娠中期流产的成年患者进行了回顾性医疗记录审查。我们提取了患者的人口统计数据;怀孕和病史;和术前,术中,和术后数据。我们评估了流产结果,包括程序定时,完成方式(单独用药或药物和程序疏散),和安全。
    所有359例患者均完成了完全流产,其中63.5%的患者仅接受药物治疗,36.5%的患者接受了手术后送备份。从第一次服用米索前列醇到胎儿排出的中位时间为6小时,在那些单独用药物完成堕胎的人中。在那些接受程序疏散作为后援的人中,手术后送的中位时间为10分钟.绝大多数患者(99.4%)没有任何不良事件。发生两起安全事件(0.6%),右韧带撕裂和子宫破裂。
    在一个门诊环境中,患者安全有效地接受了中期妊娠流产的医疗管理,并进行了程序后送备份,三分之二的人完成了单独的药物治疗。
    门诊设置可以考虑在18至24周之间进行人工流产的医疗管理,并进行手术后送备份作为安全措施,有效,和可控的孕中期流产选择。需要对患者体验和满意度进行更多研究。
    UNASSIGNED: Document the clinical outcomes of an outpatient medical management with procedural evacuation backup procedure for abortions between 18 weeks zero days to 23 weeks six days gestation.
    UNASSIGNED: We conducted a retrospective medical records review of adult patients who received mifepristone and repeated misoprostol for second trimester abortion with procedural evacuation backup at an Arizona clinic between October 2017 and November 2021. We extracted patient demographics; pregnancy and medical history; and preoperative, intraoperative, and postoperative data. We assessed abortion outcomes, including procedure timing, mode of completion (medication alone or medications and procedural evacuation), and safety.
    UNASSIGNED: All 359 patients had a complete abortion with 63.5% of patients completing with medication alone and 36.5% with procedural evacuation backup. The median time from first dose of misoprostol to fetal expulsion was six hours, among those who completed the abortion with medications alone. Of those who received procedural evacuation as backup, the median time for procedural evacuation was 10 minutes. The vast majority of patients (99.4%) did not have any adverse events. Two safety incidents (0.6%) occurred, a broad right ligament tear and a uterine rupture.
    UNASSIGNED: Patients in one outpatient setting safely and effectively received medical management of second trimester abortion with procedural evacuation backup, and two thirds completed with medications alone.
    UNASSIGNED: Outpatient settings may consider medical management of abortion between 18 and 24 weeks with procedural evacuation back-up as a safe, effective, and manageable second trimester abortion option. Additional research is needed on patient experience and satisfaction.

    背景:子宫脱垂是一种罕见的妊娠并发症,在交付方式的选择上仍未达成共识。
    方法:患者的生殖史包括流产和重达3200g的女孩的正常分娩;当前的妊娠是第三次妊娠。她的宫颈区域在阴道口外,呈红色,有明显的扩大(6×4厘米)和破碎的表面。宫颈区域也显示白色分泌物。根据她的经阴道超声检查显示,在妊娠约19周时,子宫腔中有胎儿。妇科检查显示阴道前后壁脱垂。对盆腔器官脱垂Q评分的评估表明,患者在IV期患有子宫脱垂。
    结果:口服米非司酮和米索前列醇片几天后,阴道分娩顺利进行,在头部获得一个死去的女性胎儿,25厘米的长度。孕妇的子宫颈在分娩期间没有脱出。
    结论:妊娠合并子宫脱垂和宫颈嵌顿,经阴道分娩是一种潜在的治疗选择。在分娩过程中,维持宫颈回缩和口服米索前列醇片的米非司酮给药至关重要。这种治疗可以最大限度地减少宫颈撕裂和子宫破裂的风险,帮助外科医生成功完成手术。
    BACKGROUND: Uterine prolapse is a rare complication of pregnancy, and there is still no consensus on the choice of delivery method.
    METHODS: The patient\'s reproductive history included an abortion and eutocic delivery of a girl weighing 3200 g; the current pregnancy was the third pregnancy. Her cervical region was outside the vaginal opening and was red in color, with evident enlargement (6 × 4 cm) and a broken surface. The cervical area also showed white discharge. According to her Transvaginal ultrasonography revealed a fetus in the uterine cavity at approximately 19 weeks of gestation. Gynecological examination revealed prolapse of both the anterior and posterior vaginal walls. Evaluation of the pelvic organ prolapse-Q scores showed that the patient had uterine prolapse at stage IV.
    RESULTS: Vaginal delivery was performed smoothly after oral administration mifepristone and misoprostol tablets for a few days, obtaining a dead female fetus in cephalic, 25 cm in length. The cervix of the pregnant woman did not prolapse during the delivery.
    CONCLUSIONS: For pregnancy with uterine prolapse and cervical incarceration, transvaginal delivery is a potential treatment option. Maintenance of cervical retraction and oral mifepristone administration with misoprostol tablets is crucial during this delivery. This treatment can minimize the risk of cervical lacerations and uterine rupture, helping surgeons to complete the operation successfully.

    证据强烈支持使用米非司酮-米索前列醇联合治疗在没有辅助生殖技术的怀孕中早期妊娠丢失(EPL)。没有文学存在,然而,关于这种治疗在体外受精和胚胎移植(IVF-ET)后妊娠中EPL的医学管理中的功效。这些患者不同,因为有些患者使用外源性激素补充剂来提供妊娠支持。因此,在无辅助概念和ET后,EPL的管理可能会有所不同。米非司酮,孕激素受体拮抗剂,与米索前列醇一起用于辅助生殖技术怀孕的EPL治疗时,可能会显示出改变的治疗效果。
    描述我们机构在体外受精和胚胎移植IVF-ET后使用米非司酮-米索前列醇管理EPL的经验。
    回顾性病例系列。
    2020年至2022年的单一学术机构。
    9例IVF-ET后超声证实EPL。
    所有9例患者都接受了体外受精,然后进行新鲜或冷冻胚胎移植。所有9人在800μg米索前列醇之前24小时接受200mg米非司酮。
    不完全流产,需要手术管理,血清人绒毛膜促性腺激素(hCG)阴性的天数。
    在包含的9个科目中,一个人的冷冻胚胎移植周期,6人修改了自然冷冻胚胎移植周期,2例接受新鲜ET。八名受试者通过一次剂量的治疗成功排出了组织,还有一个需要进行子宫抽吸.没有受试者需要额外剂量的米索前列醇。从米非司酮治疗到组织排出的平均天数为4.89±11.30天,阴性范围血清hCG的平均天数为36.89±18.59天。在最初的超声检查中,所有妊娠均有1个妊娠囊;5/9有一个卵黄囊;只有3个有胎儿心脏活动.EPL诊断时的平均胎龄为55.22±8.77天,大多数(8/9)完成了7周的妊娠。
    米非司酮-米索前列醇联合治疗似乎是IVF-ET后EPL患者的合理选择。未来,需要进行更大规模的研究,仅在各种ET方案中比较米索前列醇联合治疗.
    UNASSIGNED: Evidence strongly supports the use of mifepristone-misoprostol combination treatment for early pregnancy loss (EPL) among pregnancies conceived without assisted reproductive technologies. No literature exists, however, regarding the efficacy of this treatment in the medical management of EPL among pregnancies after in vitro fertilization and embryo transfer (IVF-ET). These patients differ as some use exogenous hormonal supplementation to provide pregnancy support. Thus, the management for EPL may differ between unassisted conceptions and those after ET. Mifepristone, a progesterone receptor antagonist, may demonstrate an altered treatment effect when used with misoprostol to manage EPL in assisted reproductive technologie-conceived pregnancies.
    UNASSIGNED: To describe our institution\'s experience using mifepristone-misoprostol to manage EPL after in vitro fertilization with embryo transfer IVF-ET.
    UNASSIGNED: Retrospective case series.
    UNASSIGNED: Single academic institution from 2020 to 2022.
    UNASSIGNED: Nine patients with ultrasound confirmed EPL after IVF-ET.
    UNASSIGNED: All 9 patients underwent in vitro fertilization followed by fresh or frozen embryo transfer. All 9 received 200 mg of mifepristone 24 hours before 800 μg of misoprostol.
    UNASSIGNED: Incomplete abortion, need for surgical management, number of days to negative serum human chorionic gonadotropin (hCG).
    UNASSIGNED: Of the 9 subjects included, one had a programmed frozen embryo transfer cycle, 6 had modified natural frozen embryo transfer cycles, and 2 underwent fresh ET. Eight subjects had successful expulsion of tissue with one dose of treatment, and one required uterine aspiration. No subjects required additional dosing of misoprostol. The mean number of days elapsed from mifepristone treatment to tissue expulsion was 4.89 ± 11.30 days and the mean days to negative-range serum hCG was 36.89 ± 18.59 days. At the initial ultrasound, all pregnancies had one gestational sac seen; 5/9 had a yolk sac; only 3 had fetal cardiac activity. The mean gestational age at the time of EPL diagnosis was 55.22 ± 8.77 days, with the majority (8/9) having completed 7 weeks gestation.
    UNASSIGNED: Mifepristone-misoprostol combination treatment appears to be a reasonable option for those with EPL after IVF-ET. Future, larger-scale studies are needed comparing combination treatment with misoprostol only among various ET protocols.

    背景:米非司酮,也称为RU-486,是一种与合成代谢类固醇具有相似化学结构的抗孕激素类固醇。作为单剂量与米索前列醇联合使用,米非司酮用于诱导药物流产。长期以较高剂量施用的米非司酮也被批准用于治疗皮质醇增多症。仅有2例米非司酮相关肝损伤的报道,在这两种情况下,在库欣综合征的背景下。我们报告了第三例米非司酮引起的库欣综合征患者肝损伤,其独特的组织学发现可深入了解米非司酮和合成代谢类固醇肝损伤的病理生理学。
    方法:患者是一名63岁的白人女性库欣病,既往无肝病史。她开始服用米非司酮和司马鲁肽。开始使用米非司酮90天后,她出现了深黄疸,严重瘙痒,疲劳,和恶心。肝脏检查显示肝细胞/胆汁淤积混合模式。病毒和自身免疫性血清学均为阴性,影像学上无胆道扩张。肝活检显示严重胆汁淤积,但无胆管损伤。局灶性内膜炎存在于中央小静脉内。出现胆汁淤积症状后持续一个月,然后缓慢消退。停用米非司酮四个月后,病人的症状完全缓解,肝脏检查也正常了.RoussellUclaf因果关系评估方法评分的汇编表明可能的因果关系。
    结论:米非司酮与合成合成合成代谢/雄激素类固醇具有相似的化学结构,并且在肝损伤的临床表现上有许多相似之处。该病例与其他2例报道的病例具有相似的临床特征。在我们的患者中观察到内皮炎可能提供了米非司酮之间的机械联系,或一般的合成代谢类固醇,和血管并发症的发展,如骨质疏松。
    BACKGROUND: Mifepristone, also known as RU-486, is an anti-progestational steroid with similar chemical structure to anabolic steroids. Given as a single dose in conjunction with misoprostol, mifepristone is used to induce medical abortion. Mifepristone administered chronically at a higher dose is also approved for the management of hypercortisolism. There have been only 2 reported cases of mifepristone associated liver injury, in both cases, in the setting of Cushing syndrome. We report a third patient with Cushing syndrome with mifepristone induced liver injury with unique histological findings that provide insight to the pathophysiology of liver injury in mifepristone and anabolic steroids.
    METHODS: Patient is a 63-year-old Caucasian female Cushing disease with no prior history of liver disease. She was started on mifepristone and semaglutide. Ninety days after initiating mifepristone, she developed deep jaundice, severe pruritus, fatigue, and nausea. Liver tests revealed a mixed hepatocellular/cholestatic pattern. Viral and autoimmune serologies were negative and there was no biliary dilatation on imaging. Liver biopsy showed severe cholestasis but no bile duct injury. Focal endothelialitis was present within a central venule. Cholestatic symptoms persisted for one month after presentation before slowly subsiding. Four months after stopping mifepristone, the patient\'s symptoms completely resolved, and liver tests became normal. Compilation of Roussell Uclaf Causality Assessment Method score indicated probable causality.
    CONCLUSIONS: Mifepristone shares a similar chemical structure as synthetic anabolic/androgenic steroids and there are many similarities in the clinical presentation of liver injury. This case and the 2 other reported cases share similar clinical characteristics. The observation of endothelialitis in our patient may provide a mechanistic link between mifepristone, or anabolic steroids in general, and the development of vascular complications such as peliosis.

    背景:近年来,许多临床试验使用低剂量米非司酮来控制子宫肌瘤,其中一些已经取得了良好的效果。然而,根据经典的概念,长期服用米非司酮可引起子宫内膜恶变,超低剂量米非司酮对子宫肌瘤的疗效尚不确定。研究人员缺乏长期使用米非司酮治疗的子宫肌瘤病例(超过一年)。
    方法:一名47岁的妇女因贫血而去医院。
    方法:患者诊断为子宫平滑肌瘤。
    方法:患者拒绝手术建议,患者连续接受超低剂量(12.5mg/5日)米非司酮单药治疗4年.
    结果:子宫平滑肌瘤稳定,贫血等症状消失,和月经周期,肝肾功能,肿瘤标志物正常.
    结论:从我们的案例来看,长期的,超小剂量米非司酮治疗子宫肌瘤比常规治疗安全有效。
    BACKGROUND: In recent years, many clinical trials have used low-dose mifepristone to control uterine fibroids, some of which have achieved good results. However, according to the classic concept, long-term use of mifepristone could induce malignant transformation of the endometrium, and the effect of ultra-low-dose of mifepristone on uterine fibroids is still uncertain. Researchers are short on cases of uterine fibroids treated with mifepristone for long periods (more than a year).
    METHODS: A 47-year-old woman went to the hospital because of anemia.
    METHODS: The patient was diagnosed with uterine leiomyoma.
    METHODS: The patient refused the suggestion of surgery, she was continuously treated with an ultra-low-dose (12.5 mg per 5 days) of mifepristone monotherapy for 4 years.
    RESULTS: The uterine leiomyoma was stable, anemia and other symptoms disappeared, and the menstrual cycle, liver and kidney function, and tumor markers were normal.
    CONCLUSIONS: Judging from our case, long-term, ultra-low-dose mifepristone for uterine fibroids treatment was safe and more effective than conventional therapy.
