    目的:我们介绍了Ebstein异常患者Starnes术后右心室(RV)康复的一系列病例,应用三尖瓣(TV)的锥形修复以实现双心室或1.5心室生理。
    方法:这是来自北美两个机构的回顾性数据库分析。我们纳入了Starnes手术后所有连续的Cone修复病例。数据表示为中值和四分位距(IQR)。
    结果:11例患者在初次Starnes姑息治疗后,于2019年至2023年接受了RV康复治疗,中位年龄为27个月(IQR20.5)。在进行Starnes手术之前,所有人都病危;四个人在体外膜氧合。在圆锥修复之前,Starnes贴片的术前返流速度中位数为1.65m/s(IQR1.3).在圆锥手术期间,9名患者需要同时进行PV修复,其中三个需要跨环形单核斑块。四名患者成功地改行了双心室修复术,7例既往有Glenn的患者实现了1.5个心室循环。没有心脏传导阻滞,也没有死亡。在11个月的中位随访时间(IQR21.5)中,有7例患者有轻微的反流,三个轻度和一个中度三尖瓣反流。没有明显的电视狭窄;尽管有一名患者出现严重的RV功能障碍,但所有患者在最后一次随访中的功能状态均良好。
    结论:Starnes手术后,圆锥修复允许房车康复,导致轻微或轻度的电视反流在中期随访中持续。Starnes程序是一种可重复的技术,不再使患者终生单心室生理。
    OBJECTIVE: We present a case series of Right Ventricle (RV) rehabilitation after Starnes in patients with Ebstein anomaly, applying the Cone repair of the tricuspid valve (TV) to achieve biventricular or 1.5-ventricle physiology.
    METHODS: This is a retrospective database analysis from two institutions in North America. We included all consecutive cases of Cone repair after the Starnes procedure. The data are expressed as median and interquartile range (IQR).
    RESULTS: Eleven patients underwent RV rehabilitation between 2019 and 2023 after initial Starnes palliation with a median age of 27 months (IQR 20.5). All were critically ill before their Starnes procedure; four were on extracorporeal membrane oxygenation. Before the Cone repair, the median pre-operative regurgitant velocity at the Starnes patch was 1.65 m/s (IQR 1.3). During the Cone procedure, nine patients required a concomitant PV repair, of which three required a transannular monocusp patch. Four patients were successfully rerouted to a two-ventricle repair, and seven patients with a previous Glenn achieved 1.5 ventricle circulation. There was no heart block and no deaths. Seven patients had trivial regurgitation in a median follow-up of eleven months (IQR 21.5), three mild and one moderate tricuspid regurgitation. There was no significant TV stenosis; all patients had good functional status at the last follow-up despite severe RV dysfunction in one patient.
    CONCLUSIONS: After the Starnes procedure, the Cone repair allowed RV rehabilitation, resulting in trivial or mild TV regurgitation sustained in midterm follow-up. The Starnes procedure is a reproducible technique that no longer commits patients to lifetime single ventricle physiology.

    颈椎前路椎间盘切除术和融合术(ACDF)是一种常见的颈椎手术,在美国(U.S.)每年有超过137,000例。历史上,ACDF一直是一个相对安全的程序,尽管遇到了重要的解剖结构,可能有严重的并发症的风险。ACDF的一个特别危险的后遗症是撕裂椎动脉(VA)的风险。虽然VA损伤很少见(占病例的0.5%),对于外科医生来说,通过对VA解剖学的全面了解,预防这种可能致命的并发症是至关重要的.VA通常在横向工头内受到保护;但是,异常可能存在,在手术部位内发现的动脉可能比预期的更内侧或更近.本文的目的是报告在尸体标本中发现的异常,其中VA在ACDF板的2mm内行进。
    一名有冠心病病史的66岁男性因心肌梗死并发症去世。在尸体解剖期间,结果发现,供者之前曾经历过3级(C4-C7)ACDF手术,原因不明.在进一步审查中,观察到左VA在最终进入C5的横向孔之前采取异常的内侧追踪过程。在C5和C6水平上没有左前结节,在对侧的前结节/横孔上发现了明显的骨赘。
    没有发表关于VA变异体的解剖结构及其对ACDF程序的影响的研究。发现ACDF在13.2%的病例中有并发症发生率。在高达20%的美国人群中观察到VA变体,并且ACDF程序中的VA损伤具有接近0.5%的比率。随着解剖结构的变化导致更高的受伤风险,外科医生在手术前需要采取进一步的预防措施,包括订购计算机断层扫描血管造影或磁共振血管造影胶片。了解VA及其变体的详细解剖结构至关重要。利用骨科脊柱外科医生的观点,本研究补充了ACDF手术中潜在VA异常的相关文献.
    UNASSIGNED: Anterior cervical discectomy and fusion (ACDF) is a common cervical procedure with more than 137,000 cases in the United States (U.S.) each year. Historically, ACDF has been a relatively safe procedure despite encountering vital anatomical structures that can risk serious complications. One particularly dangerous sequela of ACDF is the risk of lacerating the vertebral artery (VA). While VA injuries are rare (0.5% of cases), it is crucial for surgeons to prevent this potentially deadly complication with thorough knowledge of VA anatomy. The VA is commonly protected within the transverse foreman; however, anomalies can exist with the artery potentially being found more medial or proximal within the surgical site than expected. The purpose of this article is to report an anomaly found in a cadaveric specimen, where the VA courses within 2 mm of an ACDF plate.
    UNASSIGNED: A 66-year-old male with a past medical history of coronary artery disease passed away due to complications of a myocardial infarction. During cadaveric dissection, it was discovered that the donor had undergone a previous 3-level (C4-C7) ACDF procedure for an unknown reason. Under further examination, the left VA was observed to take an anomalous medially tracking course before eventually entering the transverse foramina of C5. Left anterior tubercles were absent at the level of C5 and C6 with prominent osteophytes found on the anterior tubercles/transverse foramina of the contralateral side.
    UNASSIGNED: There are no studies published on the anatomy of VA variants and their implications on ACDF procedures. ACDF was found to have complication rates in 13.2% of cases. VA variants are observed in up to 20% of the U.S. population and VA injury in ACDF procedures has a rate near 0.5%. With anatomic variations leading to a higher risk of injury, surgeons are required to take further precautionary steps before operating including ordering computed tomography angiography or magnetic resonance angiography films. Understanding the detailed anatomy of the VA and its variants is critical. Using the perspectives of orthopedic spine surgeons, this study supplements the literature on potential VA anomalies encountered in ACDF procedures.

    为了帮助放射科医生检查越来越多的计算机断层扫描(CT)扫描,自动异常检测是医学影像研究的热点。放射科医生必须通过搜索与正常健康解剖结构的任何偏差来分析CT扫描。我们提出了一种检测大脑轴向2DCT切片图像异常的方法。尽管已经进行了许多关于检测大脑磁共振图像异常的研究,CT扫描的工作很少,由于必须由所使用的模型表示的图像对比度低,因此更难以检测到异常。
    我们在第一步中使用生成对抗网络(GAN)来学习正常的大脑解剖结构,并比较两种图像重建方法:在第二步中训练编码器,并在推理过程中使用迭代优化。然后,我们分析与原始扫描的差异,以检测和定位大脑中的异常。
    我们的方法可以重建具有良好图像对比度的健康解剖结构,用于脑部CT扫描。我们在出血测试数据上获得的中位Dice评分为0.71,在测试集上获得的中位Dice评分为0.43,其他肿瘤图像来自公开可用的数据源。我们还将我们的模型与最先进的自动编码器和扩散模型进行比较,并获得定性更准确的重建。
    在训练期间没有定义异常,我们使用基于GAN的网络来学习用于脑部CT扫描的健康解剖学.值得注意的是,我们的方法不仅限于出血和肿瘤的定位,因此可用于检测结构解剖变化和其他病变.
    UNASSIGNED: To help radiologists examine the growing number of computed tomography (CT) scans, automatic anomaly detection is an ongoing focus of medical imaging research. Radiologists must analyze a CT scan by searching for any deviation from normal healthy anatomy. We propose an approach to detecting abnormalities in axial 2D CT slice images of the brain. Although much research has been done on detecting abnormalities in magnetic resonance images of the brain, there is little work on CT scans, where abnormalities are more difficult to detect due to the low image contrast that must be represented by the model used.
    UNASSIGNED: We use a generative adversarial network (GAN) to learn normal brain anatomy in the first step and compare two approaches to image reconstruction: training an encoder in the second step and using iterative optimization during inference. Then, we analyze the differences from the original scan to detect and localize anomalies in the brain.
    UNASSIGNED: Our approach can reconstruct healthy anatomy with good image contrast for brain CT scans. We obtain median Dice scores of 0.71 on our hemorrhage test data and 0.43 on our test set with additional tumor images from publicly available data sources. We also compare our models to a state-of-the-art autoencoder and a diffusion model and obtain qualitatively more accurate reconstructions.
    UNASSIGNED: Without defining anomalies during training, a GAN-based network was used to learn healthy anatomy for brain CT scans. Notably, our approach is not limited to the localization of hemorrhages and tumors and could thus be used to detect structural anatomical changes and other lesions.

    背景在这项研究中,我们的目的是报告单中心腹腔镜小儿泌尿外科手术的经验.我们旨在确定各种泌尿外科和泌尿生殖系统腹腔镜手术的可行性以及提高手术成功率的技巧。方法回顾性分析2018年6月至2023年2月在我们的诊所接受腹腔镜泌尿系统和/或泌尿生殖系统手术以诊断和治疗目的的98例患者的数据。所有手术均由同一手术团队进行。腹腔镜手术包括睾丸固定术,性腺切除术,阴道成形术,子宫切除术,肾盂成形术,肾切除术/肾部分切除术,输尿管膀胱造口术,膀胱憩室切除术,肾囊肿切除术,输尿管近端结石清除术,卵巢切除术,卵巢扭曲,oophoroopexy,和用于诊断目的的淋巴结切除。患者的手术计划是基于小儿肾脏病的决定,儿科内分泌学,儿科肿瘤科和多学科理事会。患者的人口统计学特征,手术适应症,术中数据,以及术后病理诊断和并发症,被记录下来。所有患者均行腹膜入路。手术持续时间从麻醉记录中获得,并定义为从手术切口开始到皮肤切口闭合的时间。结果患者,男性54人,女性44人。中位年龄为7.8岁。在我们的患者中观察到除Clavien-Dindo分类的1级以外的并发症。随着对不同类型的手术进行分析,估计了平均手术时间.结论在小儿泌尿外科中,腹腔镜手术应由经验丰富的外科医师进行。在准备腹腔镜手术以最大程度地减少技术和人体工程学问题时,考虑儿科患者大小的差异至关重要。我们相信每个手术都有其特定的技巧,这些应该是腹腔镜培训的一部分。此外,开发和分享这些信息对儿科泌尿科医师非常有用。
    Background In this study, we aim to report our single-center experience with laparoscopic pediatric urological surgeries. We aim to determine the feasibility of various urological and urogenital laparoscopic procedures and the tricks that increase surgical success. Methodology Data from 98 patients who underwent laparoscopic urological and/or urogenital procedures for diagnostic and therapeutic purposes in our clinic between June 2018 and February 2023 were retrospectively analyzed. All surgeries were performed by the same surgical team. Laparoscopic procedures included orchidopexy, gonadectomy, vaginoplasty, hysterectomy, pyeloplasty, nephrectomy/partial nephrectomy, ureteroneocystostomy, bladder diverticulum excision, renal cyst excision, proximal ureter stone removal, oophorectomy, ovarian detorsion, oophoropexy, and lymph node excision for diagnostic purposes. The surgical planning of the patients was based on the decisions of the pediatric nephrology, pediatric endocrinology, and pediatric oncology departments and the multidisciplinary council. Demographic characteristics of the patients, surgical indications, and intraoperative data, as well as postoperative pathological diagnoses and complications, were recorded. All patients underwent a transperitoneal approach. The duration of the operation was obtained from anesthesia records and defined as the time from the beginning of the surgical incision to the closure of the skin incision. Results Of the patients, 54 were males and 44 were females. The median age was 7.8 years. No complications other than grade 1 according to the Clavien-Dindo classification were observed in our patients. As different types of surgeries were analyzed, the mean operative duration was estimated. Conclusions The laparoscopic method should be performed by surgeons experienced in advanced surgeries in pediatric urology. It is critical to consider the difference in the size of pediatric patients in preparation for laparoscopic surgery to minimize technical and ergonomic problems. We believe that each surgery has its specific tricks and that these should be a part of laparoscopy training. Moreover, developing and sharing this information would be very useful for pediatric urologists.

    背景:交叉融合肾异位(CFRE)是一种常见的先天性异常,其中一个肾脏异常位于中线的另一侧,经常与另一个肾脏融合。然而,单个输尿管引流交叉融合肾异位是罕见的。
    方法:这里,我们报告了一例有结石病史的46岁尼泊尔男性患者的交叉融合性肾异位伴单个输尿管。计算机断层扫描显示左肾位于右侧并与右肾融合。两个肾脏的肾盂融合,和一个输尿管,位于右侧,将两个肾脏排入膀胱。建议患者定期随访。
    结论:单输尿管交叉融合肾异位是一种罕见的肾脏异常。无症状患者通常可以保守治疗。建议定期随访以监测肾功能,微积分形成,感染,和恶性变化。
    BACKGROUND: Crossed fused renal ectopia (CFRE) is a common congenital anomaly where one kidney is positioned abnormally on the opposite side of the midline, often fused with the other kidney. However, single ureter draining crossed fused renal ectopia is a rare occurrence.
    METHODS: Here, we report a case of crossed fused renal ectopia with a single ureter in a 46-year-old Nepali male who presented with history of lithuria. Computed tomography revealed that the left kidney was situated on the right side and fused with the right kidney. The renal pelvises of both kidneys were fused, and a single ureter, located on the right side, was draining both kidneys into the bladder. The patient was advised to have regular follow-ups.
    CONCLUSIONS: Crossed fused renal ectopia with a single ureter represents a rare renal anomaly. Asymptomatic patients can typically be managed conservatively. Regular follow-up is recommended to monitor renal function, calculus formation, infections, and malignant changes.

    背景:睾丸下降是由多种因素调节的生理过程。最终,胚胎/胎儿发育路径的紊乱促进阴囊疝的发生,一种先天性畸形,其特征是由于腹股沟环的异常扩张而在阴囊内存在肠部分。在猪中,一些基因与这种异常有关,但所涉及的遗传机制仍不清楚。这项研究旨在研究腹股沟环组织中可能与阴囊疝表现有关的一组基因的表达谱。
    结果:使用来自正常和阴囊疝影响的约30日龄雄性猪腹股沟环/腹股沟管的组织样品。使用qPCR进行相对表达分析以确认先前在RNA-Seq研究中鉴定的17个候选基因的表达谱。其中,肌球蛋白重链1(MYH1),Desmin(DES),和肌钙蛋白1(TNNI1)基因在各组之间差异表达,并且在受影响的动物中表达水平降低。这些基因编码参与肌肉组织形成的蛋白质,这似乎对增加腹股沟环对腹压的抵抗力很重要,这对于避免阴囊疝的发生至关重要。
    结论:腹股沟组织中肌肉候选基因的下调阐明了其原发部位与这种异常有关的遗传机制,为制定控制猪和其他哺乳动物畸形的策略提供有用的信息。
    BACKGROUND: Testicular descent is a physiological process regulated by many factors. Eventually, disturbances in the embryological/fetal development path facilitate the occurrence of scrotal hernia, a congenital malformation characterized by the presence of intestinal portions within the scrotal sac due to the abnormal expansion of the inguinal ring. In pigs, some genes have been related to this anomaly, but the genetic mechanisms involved remain unclear. This study aimed to investigate the expression profile of a set of genes potentially involved with the manifestation of scrotal hernia in the inguinal ring tissue.
    RESULTS: Tissue samples from the inguinal ring/canal of normal and scrotal hernia-affected male pigs with approximately 30 days of age were used. Relative expression analysis was performed using qPCR to confirm the expression profile of 17 candidate genes previously identified in an RNA-Seq study. Among them, the Myosin heavy chain 1 (MYH1), Desmin (DES), and Troponin 1 (TNNI1) genes were differentially expressed between groups and had reduced levels of expression in the affected animals. These genes encode proteins involved in the formation of muscle tissue, which seems to be important for increasing the resistance of the inguinal ring to the abdominal pressure, which is essential to avoid the occurrence of scrotal hernia.
    CONCLUSIONS: The downregulation of muscular candidate genes in the inguinal tissue clarifies the genetic mechanisms involved with this anomaly in its primary site, providing useful information for developing strategies to control this malformation in pigs and other mammals.

    目的:我们调查了持续泄殖腔(PC)患者接受后矢状位肛门-尿道-阴道-阴道-阴道(PSARUVP)的术后肾功能以及影响肾功能预后的因素。
    方法:对日本的244所大学和儿童医院进行问卷调查。169例患者接受PSARUVP,103名患者被纳入本研究。排除标准为无肾脏预后数据的患者。
    结果:本研究表明,肾脏异常(p=0.09),膀胱输尿管反流(VUR)(p=0.01),和积水(p=0.07)是影响肾功能下降的潜在因素。大约一半的患者肾功能正常,但有45.6%的患者肾功能下降(慢性肾病≥2期:CKD).肾功能下降(RFD)组VUR发生率明显高于保留(RFP)组(p=0.01)。RFD组的膀胱造口术明显高于RFP组(p=0.04)。尿路感染(p<0.01)和膀胱功能障碍(p=0.04)在VUR患者中明显高于无VUR患者。VUR状态与肠功能之间没有关联。
    结论:及时评估和治疗VUR以及膀胱管理可以最大程度地减少肾功能的下降。
    OBJECTIVE: We investigated the postoperative renal function in persistent cloaca (PC) patients who underwent posterior sagittal anorecto-urethro-vaginopalsty (PSARUVP) and factors influencing the renal functional outcomes.
    METHODS: A questionnaire survey was distributed to 244 university and children\'s hospitals across Japan. Of the 169 patients underwent PSARUVP, 103 patients were enrolled in the present study. Exclusion criteria was patients without data of renal prognosis.
    RESULTS: The present study showed that renal anomalies (p = 0.09), vesicoureteral reflux (VUR) (p = 0.01), and hydrocolpos (p = 0.07) were potential factors influencing a decline in the renal function. Approximately half of the patients had a normal kidney function, but 45.6% had a reduced renal function (Stage ≥ 2 chronic kidney disease: CKD). The incidence of VUR was significantly higher in the renal function decline (RFD) group than those in the preservation (RFP) group (p = 0.01). Vesicostomy was significantly more frequent in the RFD group than in the RFP group (p = 0.04). Urinary tract infections (p < 0.01) and bladder dysfunction (p = 0.04) were significantly more common in patients with VUR than in patients without VUR. There was no association between the VUR status and the bowel function.
    CONCLUSIONS: Prompt assessment and treatment of VUR along with bladder management may minimize the decline in the renal function.

    目的:观察CHARGE综合征患者在人工耳蜗植入术后的临床特点和听觉表现。以及影响听觉结果的预后因素。
    方法:回顾性队列。
    方法:高等教育中心。
    方法:对2007-2022年CHARGE综合征患者进行回顾性分析。听觉表现(CAP)评分类别用于评估CI结果,并对可能影响言语结果的因素进行了评估.
    结果:在14名CHARGE综合征儿童中,进行了22CI,6单边和8双边。CI的平均年龄为25.9个月(范围:10-62)。所有患者都有耳朵异常和发育迟缓,全耳存在耳蜗神经缺陷(CND)。在最后一次随访(平均:49.6个月),与术前测量相比,平均CAP评分显着改善(从0.36±0.81到3.21±1.70,P=.001),有6例患者(42.9%)达到4分或更高的CAP评分。然而,在单边和双边CI组之间,最终CAP评分或CAP评分变化相似.因素包括年龄,结肠瘤,CND对言语结果无显著影响(P均>.05)。
    结论:尽管CHARGE综合征具有挑战性异常,CI可以安全地进行,并且可以为显着的语音改善提供有效的贡献。CHARGE综合征患者应给予undergoCI的机会,以最大限度地提高其听力学进展。
    OBJECTIVE: To examine the clinical characteristics and auditory performance of patients with CHARGE syndrome following cochlear implantation (CI), as well as the prognostic factors affecting auditory outcomes.
    METHODS: Retrospective cohort.
    METHODS: Tertiary academic center.
    METHODS: A retrospective chart review was performed in patients with CHARGE syndrome who underwent CI from 2007 to 2022. The category of auditory performance (CAP) score was used to assess the CI outcomes, and factors that may affect the speech outcomes were also evaluated.
    RESULTS: In 14 children with CHARGE syndrome, 22 CIs were performed, 6 unilaterally and 8 bilaterally. The mean age at CI was 25.9 months (range: 10-62). All patients had ear abnormalities and developmental delays, and cochlear nerve deficiency (CND) was present in all ears. At the last follow-up (mean: 49.6 months), the mean CAP score improved significantly compared to the preoperative measure (from 0.36 ± 0.81 to 3.21 ± 1.70, P = .001), with 6 patients (42.9%) achieving a CAP score of 4 points or higher. However, between the unilateral and bilateral CI groups, the final CAP score or change in CAP score was similar. Factors including age, coloboma, and CND did not significantly affect speech outcomes (all P > .05).
    CONCLUSIONS: Even though CHARGE syndrome features challenging anomalies, CI can be conducted safely and can offer effective contribution to significant speech improvement. Patients with CHARGE syndrome should be given the opportunity to undergo CI to maximize their audiological progress.
