髌周去神经化预防全膝关节置换术后膝前疼痛

目的　依据髌周解剖学特点，探讨全膝关节置换术（total knee arthroplasty，TKA）中应用髌周电灼去神经化的临床效果。 方法　纳入82名诊断为骨性关节炎的患者（91膝），予行双侧或单侧不置换髌骨的TKA，按随机对照原则将病人分为两组，共有41名实验组患者（45膝）在TKA中接受了髌周去神经化处理，41名对照组患者（46膝）未做该处理。手术主刀为同一骨科医师，均使用相同的膝关节假体系统。主要评价项目包括膝关节KSS评分、Western Ontario and McMaster Universities（WOMAC）、Feller髌骨评分及VAS评分。 结果　82名患者术后均获随访，平均随访时间为12个月，两组病人的膝关节KSS评分、WOMAC、Feller髌骨评分及VAS评分均无显著统计学差异（P>0.05）。 结论　在TKA中行髌周电灼去神经化，不能显著改善病人的预后。     

Adductor Canal Block or Local Infiltrate Analgesia for Pain Control After Total Knee Arthroplasty? A Systematic Review and Meta-Analysis of Randomized Controlled Trials

Background

Total knee arthroplasty is a treatment option for debilitating arthritis. In the postoperative period, patients experience moderate to severe pain affecting the rehabilitation, hospital stay, and patient satisfaction. This study aims at utilizing current best evidence to determine whether adductor canal block (ACB) or periarticular injection (PAI) is a better modality for managing short-term postoperative pain and opioid consumption.

Stress Testing Versus CT Angiography in Patients With Diabetes and Suspected Coronary Artery Disease

Background

The optimal noninvasive test (NIT) for patients with diabetes and stable symptoms of coronary artery disease (CAD) is unknown.

Eficacia de la terapia con señales electromagnéticas pulsadas y transmitidas de manera dieléctrica monopolar en procesos dolorosos asociados a esclerosis múltiple. Estudio piloto

IntroductionPain is highly prevalent in patients with multiple sclerosis (MS); it is chronic in 50% of cases and is classified as nociceptive, neuropathic, or mixed-type. Pain affects quality of life, sleep, and the activities of daily living. Electrotherapy is an interesting alternative or complementary treatment in the management of pain in MS, with new innovations constantly appearing.Material and methodsThis study evaluates the effectiveness of treatment with monopolar dielectric transmission of pulsed electromagnetic fields (PEMF) for pain associated with MS. We performed a randomised, placebo-controlled clinical trial including 24 patients, who were assessed with the Brief Pain Inventory, the Multiple Sclerosis International Quality of Life questionnaire, the Beck Depression Inventory, and the Modified Fatigue Impact Scale.ResultsStatistically significant improvements were observed in maximum and mean pain scores, as well as in the impact of pain on work, personal relationships, and sleep and rest. Not significant differences were found between the treatment and placebo groups.ConclusionsTreatment with PEMF may be effective in reducing pain in patients with MS, although further research is necessary to confirm its effectiveness over placebo and to differentiate which type of pain may be more susceptible to this treatment.     

中国经肛全直肠系膜切除结构化培训尸体手术训练中学员表现分析

目的 分析参加经肛全直肠系膜切除（taTME）结构化培训尸体手术训练中学员表现。方法 针对2018年4月至2019年7月参加taTME结构化培训研讨会的学员，通过问卷调查获取数据，分析学员在尸体手术训练过程中各步骤的技术表现、术中困难及并发症以及术后标本直肠系膜完整度等结果。结果 共45名学员参加taTME结构化培训研讨会，其中39名学员返回问卷。荷包缝合方面，5名（12.8%）学员未能独立完成，7名（17.9%）学员需要经过两次或以上尝试来完成荷包缝合。在各方向直肠系膜间隙的切开分离过程中，85%～90%学员能在教员不同程度上的口头指导下亲自完成。最终标本直肠系膜完整性的评价中，系膜不完整的标本共5例（12.8%），系膜近乎完整的标本共18例（46.2%），系膜完整的标本共16例（41.0%）。术中并发症及遇到困难方面，18名（46.2%）学员进入错误间隙，1名（2.6%）学员出现直肠穿孔，4名（10.3%）学员出现荷包失败，2名（5.1%）学员出现尿道损伤。单因素分析发现只有学员培训前独立完成taTME手术的例数≥1例为术中不出现并发症的影响因素。结论 参加培训的学员在荷包缝合、直肠全层切开以及直肠系膜间隙的分离等各重要手术步骤中获得较为充足的亲自上手练习机会，较丰富的工作经验以及腹腔镜全直肠系膜切除术（TME），经肛门内镜微创手术（TEM）、经肛门微创手术（TAMIS）的手术经验并不能降低taTME手术经肛操作部分的术中并发症发生率。参加包含尸体手术训练的taTME结构化培训有助于降低术中并发症发生率并提高手术安全性。     

Research Priorities in Pelvic Venous Disorders in Women: Recommendations from a Multidisciplinary Research Consensus Panel

Pelvic venous disorders (PeVDs) in women can present with chronic pelvic pain, lower-extremity and vulvar varicosities, lower-extremity swelling and pain, and left-flank pain and hematuria. Multiple evidence gaps exist related to PeVDs with the consequence that nonvascular specialists rarely consider the diagnosis. Recognizing this, the Society of Interventional Radiology Foundation funded a Research Consensus Panel to prioritize a research agenda to address these gaps. This paper presents the proceedings and recommendations from that Panel.     

Symptomatic palliative care for children with neurodisability

Paediatric palliative care and neurodisability are two relatively new, evolving paediatric sub-specialities that have increasing relevance in the current paediatric landscape. For many people palliative care has been synonymous with end of life care, but in paediatrics it encompasses much more and is for all children with life-threatening or life-limiting conditions, from the point of diagnosis. This breadth of focus is demonstrated well through the interface between paediatric palliative care and paediatric neurodisability. In this article we explore this unique interface through the three domains of complex symptom management, advanced care planning and end of life care. We describe the practicalities involved in all three areas and highlight the importance of early referral and the process of “dual” or “parallel” planning. We cover in more depth the specific management of the symptoms: dystonia/abnormalities of muscle tone, seizures, pain, agitation, secretions, respiratory failure, and gut failure.
