  • 文章类型: Journal Article
    卵巢囊肿构成严重的健康风险,包括扭转,不孕症,和癌症,需要快速准确的诊断。超声检查通常用于筛查,然而,它的有效性受到弱对比等挑战的阻碍,斑点噪声,和图像中模糊的边界。这项研究提出了一种使用卵巢超声囊肿图像数据库的基于自适应深度学习的分割技术。引导三边滤波器(GTF)用于预处理中的降噪。分割利用自适应卷积神经网络(AdaResU-net)进行精确的囊肿大小识别和良性/恶性分类,通过野马优化(WHO)算法进行优化。优化目标函数骰子损失系数和加权交叉熵以提高分割精度。囊肿类型的分类是使用锥体扩张卷积(PDC)网络进行的。该方法的分割准确率达到98.87%,超越现有技术,从而有望提高诊断准确性和患者护理结果。
    Ovarian cysts pose significant health risks including torsion, infertility, and cancer, necessitating rapid and accurate diagnosis. Ultrasonography is commonly employed for screening, yet its effectiveness is hindered by challenges like weak contrast, speckle noise, and hazy boundaries in images. This study proposes an adaptive deep learning-based segmentation technique using a database of ovarian ultrasound cyst images. A Guided Trilateral Filter (GTF) is applied for noise reduction in pre-processing. Segmentation utilizes an Adaptive Convolutional Neural Network (AdaResU-net) for precise cyst size identification and benign/malignant classification, optimized via the Wild Horse Optimization (WHO) algorithm. Objective functions Dice Loss Coefficient and Weighted Cross-Entropy are optimized to enhance segmentation accuracy. Classification of cyst types is performed using a Pyramidal Dilated Convolutional (PDC) network. The method achieves a segmentation accuracy of 98.87%, surpassing existing techniques, thereby promising improved diagnostic accuracy and patient care outcomes.

    背景:关于将经阴道自然腔道内镜手术(vNOTES)作为卵巢囊肿的治疗选择,缺乏前瞻性临床研究证据。这项研究的目的是评估使用vNOTES治疗卵巢囊肿的可行性和安全性。
    方法:我们的研究包括18至70岁的女性,她们打算接受良性病变的手术治疗。采用分层阻断随机化将参与者分组。主要目的是评估指定组是否遵守推荐的卵巢囊肿切除术或附件切除术的手术技术,对替代手术方法没有任何偏差。
    结果:共有196名患者被纳入研究,每组的所有手术都按照指定的程序进行。其中,卵巢囊肿切除层为vNOTES组58例,传统腹腔镜(CL)组58例。附件层包括vNOTES组40例和CL组40例。利用敏感性分析,对于vNOTES组和CL组之间的比例差异,双侧95%置信下限确定为5.5%.这些下限低于10%的预定非劣效性界限。
    结论:研究结果表明,在附件切除术或卵巢囊肿切除术方面,vNOTES不亚于CL。vNOTES可以被认为是一种更微创的手术方法,因为它减少了术后疼痛,更快的恢复,没有可见的切口。总的来说,VNOTES被证明是安全的,可行,和侵入性较小的治疗选择。
    背景:本研究在中国临床试验注册中心进行了回顾性注册,注册号为ChiCTR2100052223(22-10-2021)。
    BACKGROUND: There is a scarcity of prospective clinical research evidence regarding the utilization of transvaginal natural orifice translumenal endoscopic surgery (vNOTES) as a treatment option for ovarian cysts. The objective of this study was to assess the feasibility and safety of employing vNOTES for the management of ovarian cysts.
    METHODS: Our study included women between the ages of 18 and 70 who intended to undergo surgical intervention for benign lesions. Stratified blocked randomization was employed to allocate participants into groups. The main objective was to assess whether the assigned group adhered to the recommended surgical technique for ovarian cystectomy or adnexectomy, without any deviation to alternative surgical methods.
    RESULTS: A total of 196 patients were included in the study, with all surgeries in each group being conducted according to the assigned procedures. Among them, the ovarian cystectomy layer included 58 cases in the vNOTES group and 58 cases in the conventional laparoscopy (CL) groups. The adnexectomy layer included 40 cases in the vNOTES group and 40 cases in the CL group. Utilizing a sensitivity analysis, the two-sided 95% lower confidence limit was determined to be 5.5% for the disparity in proportions between the vNOTES groups and CL groups. These lower limits fell below the predetermined non-inferiority margin of 10%.
    CONCLUSIONS: The study findings demonstrate that vNOTES was not inferior to CL in terms of adnexectomy or ovarian cystectomy. vNOTES can be considered a more minimally invasive surgical approach, as it results in reduced postoperative pain, faster recovery, and absence of visible incisions. Overall, vNOTES proves to be a safe, feasible, and less invasive treatment option.
    BACKGROUND: This study retrospectively registered with the China Clinical Trial Registry with the registration number ChiCTR2100052223(22-10-2021).

    成熟的囊性畸胎瘤(MCT)由全能细胞产生。虽然卵巢是最常见的部位,性腺外畸胎瘤非常罕见。该病例报告描述了一名20岁女性的临床细节,该女性在临床和影像学研究中发现骨盆腹部大肿块,并且CA-125水平升高。由于质量来源的不确定性,一个多学科小组建议以肠系膜囊肿作为鉴别诊断的剖腹探查术.剖腹手术显示两个卵巢正常,并显示大网膜MCT,被切除了。组织病理学证实了诊断。
    Mature cystic teratomas (MCTs) arise from totipotent cells. While the ovaries are the most common sites, extragonadal teratomas are very rare. This case report describes the clinical details of a 20-year-old woman who was found to have a large pelvi-abdominal mass on clinical and imaging studies and elevated levels of CA-125. Because of the uncertainties of the origin of the mass, a multidisciplinary team suggested exploratory laparotomy with a mesenteric cyst as a differential diagnosis. Laparotomy showed both ovaries to be normal and revealed a large omental MCT, which was excised. Histopathology confirmed the diagnosis.

    背景:囊性淋巴管瘤是由淋巴系统畸形引起的罕见良性肿瘤。肠系膜位置更不常见。
    方法:我们报告了一例63岁的绝经女性,她表现为骨盆的持续性疼痛明确肿块。关于超声波和计算机断层扫描,肿块表现为厚壁单眼同质囊肿,有利于卵巢囊腺瘤。在剖腹手术中,由于发现肿瘤包埋在回肠肠系膜,因此误诊。随后的组织病理学检查证实了良性囊性淋巴管瘤的诊断。
    结论:肠系膜囊性淋巴管瘤是成人罕见的腹膜肿瘤。临床上,它经常伪装成其他腹盆腔肿块,如卵巢囊肿。由于重叠的临床腹部表现和放射学特征,鉴别诊断通常具有挑战性。组织病理学是诊断肠系膜囊性淋巴管瘤的金标准。手术是主要治疗手段,如果手术切缘阴性,复发率较低。
    结论:肠系膜囊性淋巴管瘤通常模仿更频繁和潜在的恶性病变。在评估腹盆腔囊性肿块时,外科医生必须对这种诊断的可能性保持警惕。
    BACKGROUND: Cystic lymphangioma is rare benign tumor that results from a lymphatic system malformation. The mesenteric location is even more uncommon.
    METHODS: We report the case of a menopausal 63-year-old woman who presented with a persistent painful well-defined mass of the pelvis. On ultrasound and computed tomography, the mass appeared as thick-walled unilocular homogenous cyst in favor of an ovarian cystadenoma. During laparotomy, the misdiagnosis was confirmed as the tumor was found to be embedded in the mesentery of the ileum. Subsequent histopathological examination confirmed the benign cystic lymphangioma diagnosis.
    CONCLUSIONS: Mesenteric cystic lymphangioma is rare peritoneal tumor of the adult. Clinically, it often masquerades as other abdominopelvic masses like ovarian cysts. Differential diagnosis is often challenging because of the overlapping clinical abdominal presentation and radiological features. Histopathological is the gold standard in diagnosing mesenteric cystic lymphangioma. Surgery is the mainstay treatment, and the recurrence rate is low if negative surgical margins are achieved.
    CONCLUSIONS: Mesenteric cystic lymphangioma often mimics more frequent and potentially malignant lesions. It is essential for surgeons to remain vigilant for the possibility of this diagnosis when evaluating abdominopelvic cystic masses.

    产后卵巢功能障碍[卵巢囊肿(OC)和持续性卵泡(PF)]一直是一个重要问题。寻找有效的激素治疗以改善奶牛的繁殖性能已成为必要。
    通过针对OC和PFs的特定定制治疗,改善产后奶牛的繁殖性能和卵巢活动。
    该研究包括48头母牛,在第14天P,它接受了两个剂量的500μgIM氯前列醇,间隔14天作为预同步方案。最后一次注射后14天进行超声卵巢扫描,持续4周。根据卵巢状态将奶牛分为三组:OC(n=14),PF(n=12),和NE(n=22)。在OC组,接受500μgIM氯前列醇和100μgIMcystoriline,14天后服用第二剂氯前列醇,36小时后服用第二剂贝司他林,和24小时后的AI(GnRH+PG/PG/GnRH)。在PF组中,装有孕酮释放阴道内装置(PRID)9天;同一天,他们接受了100μg的半胱氨酸,然后在7天后接受了500μg的氯前列醇,在PRID移除AI56小时后(PRID+GnRH/PG)。在NE组中,根据发情检测,进行人工授精至28天。
    卵巢活动受到定制治疗的极大影响,导致卵泡和黄体活动增强,特别是在PGF2α注射后。OC和PF组的发情反应分别为71.43%和75.02%,分别,在AI时间。而NE组排卵率为54.5%,妊娠率为31.8%,治疗组的生殖表现显着改善。OC和PF组的排卵率分别为71.43%和75%,第一次人工授精时的妊娠率分别为64.28%和66.7%。
    提高繁殖性能并最大程度地减少首次服务时间是对OC和PFs产后奶牛进行早期病例特异性治疗的可能优势。
    UNASSIGNED: Postpartum ovarian dysfunction [ovarian cyst (OC) and persistent follicle (PF)] has been an important issue. Finding effective hormonal treatments to improve reproductive performance in dairy cows has become a necessity.
    UNASSIGNED: Improve reproductive performance and ovarian activity in postpartum cows with specific customized treatment for OC and PFs.
    UNASSIGNED: The study included 48 cows at 14 days P.P, which received two dosages of 500 μg IM cloprostenol, 14 days apart as presynchronization protocol. Ultrasound ovarian scans 14 days after the last injection for 4 weeks. The cows were divided into three groups according to ovarian status: OC (n = 14), PF (n = 12), and NE (n = 22). In the OC group, received 500 μg IM cloprostenol and 100 μg IM cystoriline, a second dose of cloprostenol 14 days later and a second dose of cystoriline 36 hours later, and AI after 24 hours (GnRH+ PG/PG/GnRH). In the PF group, was fitted with progesterone-releasing intravaginal device (PRID) for 9 days; the same day, they received 100 μg cystoreline then 500 μg cloprostenol 7 days later, after PRID removal AI 56 hours later (PRID + GnRH/PG). In the NE group, artificial insemination was implemented until 28 days depending on estrus detection.
    UNASSIGNED: The ovarian activity was greatly affected by the customized treatments, leading to enhanced follicular and luteal activity, particularly after the PGF2α injection. The OC and PF groups showed substantial estrus responses of 71.43% and 75.02%, respectively, during AI time. While the NE group had an ovulation rate of 54.5% and a pregnancy rate of 31.8%, the treatment groups showed marked improvements in reproductive performance. The ovulation rates in the OC and PF groups were 71.43% and 75% and the pregnancy rates at the 1st artificial insemination were 64.28% and 66.7%.
    UNASSIGNED: Improving reproductive performance and minimizing the time to first service are possible advantages of early case-specific treatment for postpartum cows with OC and PFs.

    一个身材矮小、智商低的19岁女孩,难以辨认的演讲,在妇科门诊部看到腹部大大扩张。她接受了调查,发现有较大的腹肾盂多囊性卵巢,无恶性特征,绝经前妇女的CA125水平在正常范围内。她的促甲状腺激素(TSH)显着升高。她被诊断为未经治疗的严重甲状腺功能减退伴良性巨大卵巢囊肿,构成囊肿破裂和迫在眉睫的并发症的严重风险。父母得到了建议,他们接受了风险,同意保守治疗.左甲状腺素替代疗法开始,一个月后,她的TSH水平恢复正常.治疗一个月后的随访超声检查显示卵巢囊肿大小明显减小。继续进行甲状腺替代治疗,三个月后,囊肿消失了,和卵巢,小得多,卵巢形态多囊。仔细分析临床体征,调查,适当的治疗有助于避免不必要的手术。
    A 19-year-old girl with a short stature and presenting low intelligence quotient, illegible speech, and a greatly distended abdomen was seen at the gynecological outpatient department. She underwent investigation and was found to have large abdominopelvic multicystic ovaries with no malignant features and CA125 levels within the normal range for premenopausal women. Her thyroid-stimulating hormone (TSH) was markedly elevated. She received a diagnosis of untreated severe hypothyroidism with benign giant ovarian cysts, posing a grave risk of cyst rupture and imminent complications. The parents were counseled, and they accepted the risk, agreeing to conservative therapy. Levothyroxine replacement therapy was initiated, and after one month, her TSH levels normalized. Follow-up ultrasonography after one month of her therapy revealed a marked decrease in ovarian cyst size. Thyroid replacement therapy was continued, and at the end of three months, the cysts disappeared, and the ovaries, much smaller, showed polycystic ovarian morphology. Careful analysis of clinical signs, investigations, and appropriate therapy helped avoid unnecessary surgery.

    多囊卵巢综合征(PCOS)是一种常见的内分泌疾病,影响育龄妇女,其特征是荷尔蒙失衡导致代谢和生殖失调。急性心肌梗死(AMI)是一种危重的心血管事件,传统上在老年人群中观察到,但在具有不同医学背景的年轻人中越来越多。PCOS女性追求辅助生殖技术(ART)以解决不孕症可能会进一步使心血管风险复杂化,因为涉及外源性激素操作。该病例报告描述了一名27岁的患有PCOS的女性接受ART治疗的罕见AMI表现。尽管没有传统的心血管危险因素,患者表现出典型的AMI症状和诊断特征.及时的认可和干预促进了成功的管理和有利的结果。该病例强调了在有复杂病史的年轻女性中考虑非典型心血管表现的重要性。需要提高医疗保健提供者的意识。多学科合作对于全面的风险评估至关重要,预防,以及在这个人群中量身定制的管理策略。需要进一步的研究来阐明PCOS之间复杂的相互作用,ART,和心血管结果,从而优化临床护理和提高生殖结果在这个脆弱的队列。加强对这些关系的理解对于指导基于证据的干预措施至关重要,这些干预措施旨在减轻接受生育治疗的PCOS妇女的心血管风险和改善整体健康结果。
    Polycystic ovary syndrome (PCOS) is a prevalent endocrinological disorder affecting women of reproductive age, characterized by hormonal imbalances leading to metabolic and reproductive dysregulations. Acute myocardial infarction (AMI) represents a critical cardiovascular event, traditionally observed in older populations but increasingly identified in younger individuals with diverse medical backgrounds. The pursuit of assisted reproductive technology (ART) by women with PCOS to address infertility may further complicate cardiovascular risks due to the exogenous hormonal manipulations involved. This case report delineates a rare presentation of AMI in a 27-year-old vicenarian woman with PCOS undergoing ART treatment. Despite the absence of conventional cardiovascular risk factors, the patient exhibited typical symptoms and diagnostic features of AMI. Prompt recognition and intervention facilitated successful management and favorable outcomes. This case underscores the importance of considering atypical cardiovascular presentations in young women with complex medical histories, necessitating heightened awareness among healthcare providers. Multidisciplinary collaboration is imperative for comprehensive risk assessment, prevention, and tailored management strategies in this population. Further research is warranted to elucidate the intricate interplay between PCOS, ART, and cardiovascular outcomes, thereby optimizing clinical care and enhancing reproductive outcomes in this vulnerable cohort. An enhanced understanding of these relationships is essential for guiding evidence-based interventions aimed at mitigating cardiovascular risks and improving overall health outcomes in women with PCOS undergoing fertility treatments.

    背景:脾脏(或异位脾脏)是指过度移动的脾脏,导致其从正常解剖位置移位到通常在下腹部或盆腔中。虽然超声通常是第一种使用的放射学模式,计算机断层扫描(CT)显示清晰的图像和辅助诊断。在没有适当成像模式的情况下,或者操作员没有经验,诊断为脾脏游走可漏诊。
    方法:一名22岁的未婚Sindhi女性到急诊室(ER)就诊,有5天的间歇性严重下腹痛病史。当地医生的超声检查提示卵巢囊肿。在我们的设施进行的超声骨盆和后来的CT扫描报告了一个肿大的游走脾脏,其椎弓根扭转和梗塞。行剖腹探查术和脾切除术。发现脾脏肿大,脾静脉扭转,大网膜包裹在肿块上的动脉供血血栓形成。患者在手术后出现血小板增多症,但其他情况良好,2天后出院。
    结论:继发于脾脏游走的脾扭转对诊断可能具有挑战性,特别是在资源有限的情况下,超声可能是唯一可用的模式。及时诊断和适当干预是挽救生命和脾脏的关键。
    BACKGROUND: Wandering spleen (or ectopic spleen) refers to a hyper-mobile spleen resulting in its displacement from the normal anatomical position to usually in the lower abdominal or pelvic cavity. While ultrasound is often the first radiological modality used, Computed Tomography (CT) shows a clear picture and aides to reach a diagnosis. In circumstances where appropriate imaging modalities are not available, or the operator is inexperienced, diagnosis of wandering spleen can be missed.
    METHODS: A 22-nulligravida unmarried Sindhi female had presented to the Emergency Room (ER) with a 5-day history of intermittent severe lower abdominal pain. An ultrasound at a local practitioner had suggested an ovarian cyst. Ultrasound-pelvis and later CT scan at our facility reported an enlarged wandering spleen with torsion of its pedicle and infarction. Exploratory laparotomy with splenectomy was done. An enlarged wandering spleen was found with torsion of the splenic vein and thrombosed arterial supply from omentum wrapped over the mass. The patient developed thrombocytosis post-surgery but otherwise did well and was discharged after 2 days.
    CONCLUSIONS: Splenic torsion secondary to a wandering spleen can be challenging to diagnose, especially in resource limited settings where ultrasound might be the only modality available. Timely diagnosis and proper intervention are key to saving the life and the spleen.
