Dorsal suspension for Morton’s neuroma: A comparison with neurectomy

BackgroundThe purpose of this study was to investigate and compare the clinical outcomes of dorsal suspension with those of neurectomy for the treatment of Morton’s neuroma.MethodsWe conducted a retrospective study of dorsal suspension and neurectomy group. The dorsal suspension was performed by dorsal transposition of neuroma over the dorsal transverse ligament after neurolysis. The visual analog scale (VAS), the Foot and Ankle Ability Measure (FAAM), postoperative satisfaction, and complications were evaluated.ResultsBoth groups reported significant pain relief, and there were no significant differences between the groups with respect to postoperative pain. The postoperative FAAM outcomes showed no significant between-group differences. Satisfaction analysis showed ‘excellent’ and ‘good’ results in the dorsal suspension and neurectomy groups (95% and 77.7%, respectively). Complications of numbness and paresthesia reported in the dorsal suspension group (5% and 5%, respectively) were significantly fewer than those of neurectomy group (61.1% and 33.3%, respectively) (both, p < .05).ConclusionsWith its favorable results, dorsal suspension can be another operative option for the treatment of Morton’s neuroma.Level of Evidence: Level III, retrospective comparative case series.     

The increase in bone mineral density by bisphosphonate with active vitamin D analog is associated with the serum calcium level within the reference interval in postmenopausal osteoporosis

Objectives: To examine the factors associated with increase in lumbar spine bone mineral density (LS-BMD) by bisphosphonates (BPs) with active vitamin D analog (aVD).

Methods: Two independent postmenopausal osteoporotic patients treated by BPs with aVD for 24 months (Study 1: n?=?93, Study 2: n?=?99) were retrospectively analyzed.

Results: In Study 1, LS-BMD of the patients significantly increased for 24 m (5.4%, p?r²: 0.088, p?=?.02). While average sCa of the patients was 9.2?mg/dL before treatment, it increased time-dependently to 9.6?mg/dL for 24 m by treatment. As each patient had their LS-BMD five times during the study, there were four instances of %LS-BMD in each patient, resulting in 372 instances of %LS-BMD in Study 1. The smallest Akaike’s information criterion value for the most appropriate cut-off levels of sCa for %LS-BMD by treatment every 6 m was 9.3?mg/dL. The %LS-BMD by treatment for 6 m during 24 m period in patients with sCa ≥9.3?mg/dL (1.5%) was significantly higher than that in patients with sCa <9.3?mg/dL (0.8%, p?=?.038). The results of Study 2 were similar to those of Study 1, confirming the phenomena observed.

Conclusion: sCa was associated with an increased LS-BMD by BPs with aVD.     

磁敏感加权成像黑质“燕尾征”在帕金森病中的诊断价值

目的:探讨3.0 T磁敏感加权成像(susceptibility weighted imaging,SWI)中"燕尾征"缺失在帕金森病(Parkinson's dis-ease,PD)的诊断价值并分析黑质小体-1 (nigrosome-1)可视化与PD患者临床资料的相关性.方法:收集2017年9月至2019年11月于重庆医科大学附属第一医院神经内科住院的50例PD患者及年龄、性别与之匹配的57例非PD患者.所有受试者均接受3.0 T头颅SWI检查.在获得的SWI图像上,由2名临床医师采用盲法独立对双侧"燕尾征"进行评估.一侧"燕尾征"缺失即判定为PD.计算"燕尾征"缺失诊断PD的灵敏度、特异度、预测值和准确度,并分析nigrosome-1可视化与PD患者临床资料的相关性.结果:以临床诊断作为金标准,45例PD患者判断正确,评估者之间的一致性很高(k=0.963,P=0.000)."燕尾征"缺失诊断PD的灵敏度为90.0％,特异度为91.2％,阳性预测值为90.0％,阴性预测值为91.2％,准确度为90.7％.44例PD患者临床症状不对称,其中32例患者nigrosome-1可视化不对称.PD患者nigrosome-1可视化偏侧和临床症状偏侧比较差异无统计学意义(x2=5.756,P=0.056).11例PD患者双侧nigrosome-1全部缺失,纳入全部缺失组,其余PD患者为非全部缺失组.全部缺失组和非全部缺失组患者的汉密尔顿抑郁量表评分差异有统计学意义(U=126.500,P=-0.038),而病程、帕金森病统一评定量表第Ⅲ部分、改良Hoehn-Yahr(H-Y)分级、简易智能状态量表和蒙特利尔认知评估量表评分差异均无统计学意义(P=0.768、0.140、0.839、0.054、0.067).结论:"燕尾征"缺失诊断PD的准确率较高,缺失程度可能与PD患者的抑郁程度有关,对PD的诊断有一定参考价值.     

Hiperplasia endotelial papilar intravascular (tumor Masson) de localización ginecológica

Intravascular papillary endothelial hyperplasia or Masson's tumour is a non-neoplastic vascular lesion of reactive character. It is a rare diagnosis, clinically non-specific and with diverse locations. It is essential to take it into consideration and make a differential diagnosis with malignant vascular tumours such as angiosarcoma. Pathological study is fundamental for diagnosis. Treatment consists of complete resection of the tumour, including sufficiently wide margins to avoid recurrence.The case reported is an exceptional event, because of the pelvic location of the Masson's tumour that was diagnosed as part of the surgical staging of an ovarian cancer.     

Safety profile of the adjuvanted recombinant zoster vaccine: Pooled analysis of two large randomised phase 3 trials

Background

The ZOE-50 (NCT01165177) and ZOE-70 (NCT01165229) phase 3 clinical trials showed that the adjuvanted recombinant zoster vaccine (RZV) was ≥90% efficacious in preventing herpes zoster in adults. Here we present a comprehensive overview of the safety data from these studies.
