Purpose Meniscal injuries are a common occurrence in sports-related activities, often leading to pain, reduced joint function, and impaired athletic performance. This study aimed to evaluate the role of ultrasound-guided intra-articular platelet-rich plasma (PRP)-rich fluid injection which was obtained through serial centrifugation in the treatment of meniscal injuries resulting from sports activities. Materials and Methods A prospective study was conducted involving 54 cases with grade I, II, and III meniscal injuries, aged 18 and 43 years. PRP-rich fluid was prepared by subjecting autologous blood samples to a two-step centrifugation process. Patients were assessed pretreatment and at regular intervals posttreatment. Results Patients reported reduced pain and improved joint functionality following treatment. Average age of the patients was 34.4 years, and average follow-up period was 275.1 days. It is noteworthy that no cases of bilateral meniscal injuries were identified; indicating that the focus was primarily on single knee injuries. Predominance of grade II injuries suggests that the PRP intervention might be particularly effective in addressing more severe meniscal tears. Conclusion The results of our study provide compelling evidence for the positive impact of PRP augmentation in meniscus repair. Our findings indicate that PRP therapy has the potential to bring about substantial benefits for individuals with meniscus tears of the knee, particularly in terms of pain relief and enhanced functional capabilities.
目的 半月板损伤是运动相关活动中的常见损伤,通常会导致疼痛、关节功能减退和运动表现受损。本研究旨在评估超声引导下关节内注射通过连续离心获得的富血小板血浆(PRP)在治疗运动导致的半月板损伤中的作用。材料与方法 一项前瞻性研究涉及 54 例 I 级、II 级和 III 级半月板损伤病例,年龄分别为 18 岁和 43 岁。自体血液样本经过两步离心过程制备出富含 PRP 的液体。治疗前和治疗后定期对患者进行评估。结果 患者表示治疗后疼痛减轻,关节功能得到改善。患者的平均年龄为 34.4 岁,平均随访时间为 275.1 天。值得注意的是,没有发现双侧半月板损伤的病例,这表明治疗主要集中在单膝关节损伤上。II级损伤居多,这表明 PRP 干预疗法可能对治疗更严重的半月板撕裂尤为有效。结论 我们的研究结果为 PRP 增量在半月板修复中的积极作用提供了令人信服的证据。我们的研究结果表明,PRP疗法有可能为膝关节半月板撕裂患者带来巨大的益处,尤其是在缓解疼痛和增强功能方面。

Objective This article evaluates the ability of low-energy (40 keV) virtual monoenergetic images (VMIs) in the local diagnosis of cervical cancer compared with that of conventional computed tomography (C-CT) and magnetic resonance imaging (MRI), using clinicopathologic staging as a reference. Methods This prospective study included 33 patients with pathologically confirmed cervical cancer who underwent dual-energy CT and MRI between 2021 and 2022. The contrast-to-noise ratio (CNR) of the tumor-to-myometrium was compared between C-CT and VMI. Additionally, sensitivity, specificity, and area under the receiver operating characteristic curve (AUC) for each local diagnostic parameter were compared between C-CT, VMI, and MRI. Interradiologist agreement was also assessed. Results The mean CNR was significantly higher on VMI (p = 0.002). No significant difference in AUC was found between C-CT and VMI for all local diagnostic parameters, and the specificity of VMI was often significantly less than that of MRI. For parametrial invasion, mean sensitivity, specificity, and AUC for C-CT, VMI, and MRI were 0.81, 0.99, 0.93; 0.64, 0.35, 0.79; and 0.73, 0.67, 0.86, respectively, and MRI had significantly higher specificity and AUC than that of VMI (p = 0.013 and 0.008, respectively). Interradiologist agreement was higher for VMI than C-CT and for MRI than VMI. Conclusion The CNR of VMI was significantly higher than C-CT and interradiologist agreement was better than with C-CT; however, the overall diagnostic performance of VMI did not significantly differ from C-CT and was inferior to MRI. VMI was characterized by low specificity, which should be understood and used for reading.
目的 本文以临床病理分期为参考,评估低能量(40 keV)虚拟单能量图像(VMI)与传统计算机断层扫描(C-CT)和磁共振成像(MRI)相比,在宫颈癌局部诊断中的能力。方法 这项前瞻性研究纳入了 33 名病理确诊的宫颈癌患者,他们在 2021 年至 2022 年期间接受了双能 CT 和 MRI 检查。比较了 C-CT 和 VMI 的肿瘤-子宫对比度-噪声比(CNR)。此外,还比较了 C-CT、VMI 和 MRI 对每个局部诊断参数的敏感性、特异性和接收器操作特征曲线下面积 (AUC)。同时还评估了放射科医生之间的一致性。结果 VMI 的平均 CNR 明显更高(p = 0.002)。在所有局部诊断参数上,C-CT 和 VMI 的 AUC 均无明显差异,而 VMI 的特异性往往明显低于 MRI。对于宫旁侵犯,C-CT、VMI 和 MRI 的平均敏感性、特异性和 AUC 分别为 0.81、0.99、0.93;0.64、0.35、0.79;0.73、0.67、0.86,MRI 的特异性和 AUC 明显高于 VMI(P = 0.013 和 0.008)。VMI 比 C-CT 和 MRI 的医师间一致性更高。结论 VMI 的 CNR 明显高于 C-CT,放射科医生之间的一致性也优于 C-CT;但是,VMI 的总体诊断性能与 C-CT 没有明显差异,不如 MRI。VMI 的特点是特异性低,这一点应得到理解并用于阅读。

Abstract Background  Artificial intelligence chatbots have demonstrated potential to enhance clinical decision-making and streamline health care workflows, potentially alleviating administrative burdens. However, the contribution of AI chatbots to radiologic decision-making for clinical scenarios remains insufficiently explored. This study evaluates the accuracy and reliability of four prominent Large Language Models (LLMs)—Microsoft Bing, Claude, ChatGPT 3.5, and Perplexity—in offering clinical decision support for initial imaging for suspected pulmonary embolism (PE). Methods  Open-ended (OE) and select-all-that-apply (SATA) questions were crafted, covering four variants of case scenarios of PE in-line with the American College of Radiology Appropriateness Criteria®. These questions were presented to the LLMs by three radiologists from diverse geographical regions and setups. The responses were evaluated based on established scoring criteria, with a maximum achievable score of 2 points for OE responses and 1 point for each correct answer in SATA questions. To enable comparative analysis, scores were normalized (score divided by the maximum achievable score). Result  In OE questions, Perplexity achieved the highest accuracy (0.83), while Claude had the lowest (0.58), with Bing and ChatGPT each scoring 0.75. For SATA questions, Bing led with an accuracy of 0.96, Perplexity was the lowest at 0.56, and both Claude and ChatGPT scored 0.6. Overall, OE questions saw higher scores (0.73) compared to SATA (0.68). There is poor agreement among radiologists' scores for OE (Intraclass Correlation Coefficient [ICC] = −0.067, p  = 0.54), while there is strong agreement for SATA (ICC = 0.875, p  < 0.001). Conclusion  The study revealed variations in accuracy across LLMs for both OE and SATA questions. Perplexity showed superior performance in OE questions, while Bing excelled in SATA questions. OE queries yielded better overall results. The current inconsistencies in LLM accuracy highlight the importance of further refinement before these tools can be reliably integrated into clinical practice, with a need for additional LLM fine-tuning and judicious selection by radiologists to achieve consistent and reliable support for decision-making.
摘要 背景 人工智能聊天机器人已显示出增强临床决策和简化医疗保健工作流程的潜力,有可能减轻行政负担。然而,人工智能聊天机器人对临床场景中放射学决策的贡献仍未得到充分探索。本研究评估了微软必应、Claude、ChatGPT 3.5 和 Perplexity 这四种著名的大型语言模型(LLM)在为疑似肺栓塞(PE)的初始成像提供临床决策支持方面的准确性和可靠性。方法 设计了开放式(OE)和全选适用(SATA)问题,涵盖符合美国放射学会适当性标准(American College of Radiology Appropriateness Criteria®)的四种肺栓塞病例情景。这些问题由来自不同地区和机构的三位放射科医生向 LLM 提出。根据既定的评分标准对回答进行评估,OE 回答的最高得分为 2 分,SATA 问题的每个正确答案为 1 分。为便于比较分析,对得分进行了归一化处理(得分除以最高得分)。结果 在 OE 问题中,Perplexity 的准确率最高(0.83),而 Claude 的准确率最低(0.58),Bing 和 ChatGPT 的准确率均为 0.75。在 SATA 问题中,Bing 的准确率最高,为 0.96;Perplexity 的准确率最低,为 0.56;Claude 和 ChatGPT 的准确率均为 0.6。总体而言,OE 问题的得分(0.73)高于 SATA 问题(0.68)。放射科医生对 OE 的评分一致性较差(类内相关系数 [ICC] = -0.067,p = 0.54),而对 SATA 的评分一致性较强(ICC = 0.875,p < 0.001)。结论 本研究揭示了不同 LLM 在 OE 和 SATA 问题上的准确性差异。Perplexity 在 OE 问题中表现优异,而 Bing 则在 SATA 问题中表现突出。OE 查询的总体结果更好。目前 LLM 准确性的不一致凸显了在将这些工具可靠地整合到临床实践中之前进一步完善的重要性,放射科医生需要对 LLM 进行额外的微调和明智的选择,以便为决策提供一致、可靠的支持。

Abstract An isolated injury to the coracobrachialis is an exceedingly uncommon occurrence, with only a handful of case reports documented in the literature. The majority of the reported cases attribute the injury to either direct trauma to the affected area or the contraction of the muscle, leading to the rupture of the muscle belly. In this article, we reported a case of indirect traumatic partial rupture of the coracobrachialis muscle, accompanied by a substantial hematoma at the proximal myotendinous junction had an unusual presentation of glenohumeral internal rotation deficit. To the best of our knowledge, no other case of isolated coracobrachialis injury has been reported in a bowler/cricketer.
摘要 角肱骨肌的孤立性损伤极为罕见,文献中仅有极少数病例报告。大多数报告的病例都是由于患处受到直接创伤或肌肉收缩导致肌腹断裂所致。在本文中,我们报告了一例间接外伤性肱角肌部分断裂病例,该病例伴有近端肌腱交界处的大量血肿,并伴有不寻常的盂肱关节内旋障碍。据我们所知,还没有其他关于保龄球/板球运动员孤立性角肱肌损伤的报道。

Abstract Cerclage wiring may be used to optimize the stability of intramedullary nail or plate fixations in comminuted proximal femoral fractures, periprosthetic fractures, and other selected cases. In this article, we presented a novel case of iatrogenic sciatic nerve entrapment from cerclage wiring used to supplement intramedullary nail fixation. We also illustrate and highlight the role of ultrasound in assessing the sciatic nerve to make a timely diagnosis.

Abstract Background  The Pre-Conception and Pre-Natal Diagnostic Techniques (Prohibition of Sex Selection) Act (PC&PNDT Act), 1994 was enacted to prevent sex determination and female feticide. As a mandatory statutory requirement, All India Institute of Medical Sciences, New Delhi, India has to renew its PC&PNDT license after every 5 years. Aim  The current study was undertaken with an objective to delineate in detail, the process of PC&PNDT license renewal, and the challenges dealt with while submitting the renewal application. Methods and Material  An observational descriptive study was conducted from February to July 2022. The renewal process was categorized into preapplication, application, and postapplication phases. The requisite documents and data were collected from the Hospital Establishment Section and Medical Records Department. Results  The preapplication phase involved obtaining details from 24 departments, with 20 responding initially. Challenges included incomplete documents and deficient details. The application phase required consolidation, affidavits, form filling, and fee payment. Postapplication, an inspection was conducted, and the renewal certification was obtained. Conclusion  The study highlights the complexities of renewal of PC&PNDT license of a large multispecialty tertiary care teaching hospital. Planning leads obtained during various phases could serve as a guiding template for other similar teaching hospitals. The study suggests the need for digitalization and streamlining of documentation process to ease out the renewal process and hence contribute to better patient care at large.
摘要 背景 1994 年颁布的《受孕前和产前诊断技术(禁止性别选择)法》(PC&PNDT 法)旨在防止性别鉴定和堕胎。作为一项强制性法定要求,印度新德里全印度医学科学研究所必须每 5 年更新一次 PC&PNDT 许可证。本研究旨在详细描述 PC&PNDT 许可证的续期过程,以及在提交续期申请时遇到的挑战。方法和材料 2022 年 2 月至 7 月期间进行了一项观察性描述研究。更新过程分为申请前、申请中和申请后三个阶段。研究人员从医院编制科和医疗记录部收集了必要的文件和数据。结果 申请前阶段需要从 24 个部门获取详细资料,其中 20 个部门做出了初步回应。面临的挑战包括文件不完整和细节不充分。申请阶段需要进行合并、宣誓、填表和缴费。申请后进行了检查,并获得了续期证书。结论 本研究强调了一家大型多专科三级护理教学医院 PC&PNDT 许可证续期的复杂性。各阶段获得的规划线索可作为其他类似教学医院的指导模板。研究表明,有必要实现文件流程的数字化和简化,以简化续证流程,从而有助于更好地为广大患者提供医疗服务。

Abstract Aim  This article determines the compliance rates with low-dose aspirin (LDA) and outcomes in a group of pregnant women identified at high risk for preeclampsia (PE) and fetal growth restriction (FGR) at 11 to 14 gestational weeks (GWs) in a rural district of central India. Methods  A single, experienced fetal radiologist assessed all enrolled pregnant women using trimester-specific antenatal screening protocols that included mean arterial blood pressure assessment, and fetal ultrasound and Doppler studies. A trimester-specific individualized risk for preterm PE and FGR was estimated for each woman. Pregnant women categorized as high risk for preterm PE or FGR based on a 1 in 150 criteria at 11 to 14 GW were recommended LDA 150 mg once daily at bedtime. Outcome measures included compliance with LDA assessed, incidence of PE and FGR, preterm delivery (< 37 GW), birth weight, stillbirths, and perinatal mortality. Results  The data of 488 pregnant women with longitudinal trimester-specific assessments from 11 to 14 GW till childbirth was analyzed. At the 3rd trimester assessment, 215 (80.83%) of the high-risk women were compliant with LDA. The incidence of PE, FGR, and preterm births was significantly higher in LDA noncompliant women, and the mean birth weight was significantly higher in LDA-compliant high-risk women. Conclusion  Good compliance for LDA is possible in rural populations with adequate counseling. Starting LDA at 11 to 14 GW for high-risk pregnant women lowered the incidence of PE, FGR, and preterm birth rates and improved birth weight in the study population.
摘要 本文确定了印度中部农村地区一组在 11-14 孕周(GWs)时被确定为子痫前期(PE)和胎儿生长受限(FGR)高风险孕妇服用低剂量阿司匹林(LDA)的依从率和结果。方法 由一名经验丰富的胎儿放射科医生对所有入组孕妇进行评估,采用特定孕期的产前筛查方案,包括平均动脉血压评估、胎儿超声和多普勒检查。对每位孕妇的早产 PE 和胎儿畸形风险进行了特定孕期的个体化估计。在怀孕 11 至 14 个月时,根据 150 分之 1 的标准被归类为早产 PE 或 FGR 高风险的孕妇被推荐服用 LDA 150 毫克,每天一次,睡前服用。结果测量包括对 LDA 的依从性评估、PE 和 FGR 的发生率、早产(< 37 GW)、出生体重、死胎和围产期死亡率。结果 对 488 名孕妇的数据进行了分析,这些孕妇从 11 至 14 个月至分娩前接受了三个月的纵向评估。在第 3 个孕期的评估中,215 名(80.83%)高危孕妇符合 LDA 要求。未遵从 LDA 的产妇的 PE、FGR 和早产发生率明显较高,而遵从 LDA 的高危产妇的平均出生体重明显较高。结论 在农村人口中,通过适当的咨询,LDA 的依从性是有可能实现的。高危孕妇在 11 至 14 GW 开始服用 LDA 可降低 PE、FGR 和早产率的发生率,并改善研究人群的出生体重。
