Repeat resection in recurrent glioblastoma (3rGBM) Trial: A randomized care trial

BackgroundThe prognosis for patients with recurrent glioblastoma (GBM) is dismal, and the question of repeat surgery at time of recurrence is common. Re-operation in the management of these patients remains controversial, as there is no randomized evidence of benefit. An all-inclusive pragmatic care trial is needed to evaluate the role of repeat resection.Methods3rGBM is a multicenter, pragmatic, prospective, parallel-group randomized care trial, with 1:1 allocation to repeat resection or standard care with no repeat resection. To test the hypothesis that repeat resection can improve overall survival by at least 3 months (from 6 to 9 months), 250 adult patients with prior resection of pathology-proven glioblastoma for whom the attending surgeon believes repeat resection may improve quality survival will be enrolled. A surrogate measure of quality of life, the number of days outside of hospital/nursing/palliative care facility, will also be compared. Centers are invited to participate without financial compensation and without contracts. Clinicians may apply to local authorities to approve an investigator-led in-house trial, using a common protocol, web-based randomization platform, and simple standardized case report forms.DiscussionThe 3rGBM trial is a modern transparent care research framework with no additional risks, tests, or visits other than what patients would encounter in normal care. The burden of proof remains on repeat surgical management of recurrent GBM, because this management has yet to be shown beneficial. The trial is designed to help patients and surgeons manage the uncertainty regarding optimal care.Clinical Trial Registrationhttp://www.clinicaltrials.gov. Unique identifier: NCT04838782.     

Anastomotic Recurrence of Colon Cancer—is it a Local Recurrence,a Second Primary,or a Metastatic Disease (Local Manifestation of Systemic Disease)?

The aim of this study is to review the literature to find out the exact etiology of anastomotic cancers of colon post resection and differentiate them between a recurrence, second primary, and metastatic disease (local manifestation of systemic disease). Web-based literature search was done, and datas collected. We searched PubMed for papers using the keywords colon cancer recurrence, anastomotic recurrence, and recurrent colon carcinoma. We also searched for systematic review in the same topic. In addition, we used our personal referrence archive. Anastomotic recurrences of colon are postulated to arise due to inadequate margins, tumor implantation by exfoliated cells, altered biological properties of bowel anastomosis, and missed synchronous lesions. Some tumors are unique with repeated recurrence after repeated resection. Duration after primary surgery plays a major role in differentiating recurrent and second primary lesions. Repeated recurrences after repeated resections have to be considered a manifestation of systemic disease or metastatic disease due to the virulence of the disease. A detailed analysis and study of patients with colonic anastomotic lesion are required to differentiate it between a recurrent, a second primary lesion, and a metastatic disease (local manifestation of a systemic disease). The nomenclature is significant to study the survival of these patients, as a second primary lesion will have different survival compared to that of recurrent lesions.     

Immunotherapy for recurrent pregnancy loss

When immunomodulation is used on an unselected population with recurrent miscarriage (RM), there is no improvement in the live birth rate. However, when the population is selected for a poor prognosis, or immune phenomena, immunotherapy has been shown to be effective. This review discusses four immunomodulatory agents, namely, paternal leukocyte immunization, intravenous immunoglobulin (IVIg), intralipid, and filgrastim. The presence of embryonic aneuploidy may confound the results of treatment, therefore creating an impression of futility when treatment may be highly effective in saving pregnancies that can be saved. Additionally, in an unselected population with RM, there is a relatively good prognosis of 60–80% for a subsequent live birth depending on whether the definition of ≥2 or ≥3 miscarriages is used. Hence, spontaneous prognosis must be taken into account, which has not been the case in previous trials.This review discusses the possible immune-mediated mechanisms of pregnancy loss and the means whereby immunotherapy may modulate these mechanisms.     

Heubner回返动脉显微外科解剖及其临床应用

目的 :为前交通动脉复合体部位显微手术避免损伤Heubner回返动脉提供相关的应用解剖学资料。方法 :对经双侧椎动脉 (VA)、颈内动脉 (ICA)乳胶灌注的尸头标本 2 2例 ,按翼点入路方向 ,在手术显微镜下解剖观测 2 0例Heubner回返动脉的起点、管径、行径及其毗邻关系。 2例模拟手术操作。结果 :(1)本组观测到 4 3支回返动脉 ,其中 39支Heubher回返动脉 ;4支副Heubner回返动脉。 (2 )Heubner回返动脉 4 6 .5 % (2 0 / 4 3)起于A2 段 ,2 5 .6 % (11/ 4 3)起于A1段 ,2 7.9% (12 /4 3)起于前交通动脉 (ACOA)水平的大脑前动脉 (ACA)。 (3)Heubner回返动脉起点管径 :左侧 0 .81± 0 .2 1mm(0 .35～ 1.17mm) ;右侧 0 .84± 0 .2 6mm(0 .37～ 1.2 1mm)。 (4 )回返动脉发出后 ,与ACA反方向成锐角 ,沿A1上壁、外侧及后内侧 ,越过ICA两分叉 ,经大脑中动脉 (MCA)始段前面穿通入脑 ,少数回返动脉行走于前穿质 (APS)的后部。A1近端 3～ 5mm或中 1/ 3段穿通支少。结论 :在前交通动脉复合体部位手术时 ,A1近端 3～ 5mm或中 1/ 3段夹闭 ,并解剖寻找、剥离Heubner回返动脉 ,可避免损伤Heubner回返动脉及其它穿通支 ,最大限度减少术后并发症

MRI诊断腰椎间盘术后粘连和突出复发

失败的下腰椎手术是个复杂的问题，由于其症状和体征不典型，单靠临床检查很难明确诊断，而脊髓造影和常规ＣＴ等检查也很难区别突出复发和硬膜外粘连。本文分析了３２例再手术患者ＭＲＩ图象，并与第二次手术所见对比，发现２７例ＭＲＩ诊断准确，３例假阳性，２例因信号缺失不能明确诊断。     

A case of recurrent Miller Fisher syndrome mimicking botulism

Abstract Miller Fisher syndrome (MFS) is a rare and usually monophasic polyradiculoneuropathy characterised by ophthalmoplegia, decreased or absent tendon reflexes, and ataxia. The objective of this study was to report a case of recurrent MFS with a clinical presentation virtually indistinguishable from botulism. The patient was a young man with two episodes of increasing external ophthalmoplegia, ptosis, and ataxia with a long asymptomatic interval in between. The second episode occurred after consumption of rotten fish and was accompanied by gastrointestinal symptoms and an anticholinergic syndrome. Very rarely, MFS can present with a recurrent course. The importance of this case of recurrent MFS lies not only in its long asymptomatic period and identical clinical presentation, but also in its instructiveness regarding the differential diagnosis of MFS, particularly life-threatening botulism.
