Endoscopic Anterior Transposition of Ulnar Nerve (EATUN) for Treatment of Tardy Ulnar Nerve Palsy

BackgroundTardy ulnar nerve palsy is the development of late onset ulnar nerve dysfunction and is usually treated by open anterior transposition of ulnar nerve. Open technique is done using a longitudinal incision about 6–8 inch. in length with chances of development of medial antebrachial cutaneous nerve neuromas.PurposeIn this study, we describe the technique of Endoscopic Anterior Transposition of Ulnar Nerve (EATUN procedure) to treat tardy ulnar nerve palsy and analyze the results.MethodsSeven patients diagnosed to have tardy ulnar nerve palsy was treated by EATUN. The humerus-elbow-wrist angle (HEW), pre- and post-operative intrinsic muscle power and sensory assessment, Dellon scores, and the Q-DASH was analyzed.ResultsThe minimum follow-up was 12 months (Mean 27.4 months, Range 12–36 months). Improvement in Dellon and Q-DASH scores following EATUN procedure was statistically significant. There was objective improvement of intrinsic muscle power and sensation on follow-up, though not statistically significant. No instance of neuroma of the medial cutaneous nerve of forearm was noted.ConclusionsThe endoscopic anterior transposition of the ulnar nerve is a good option in surgical management of tardy ulnar nerve palsy.Level of evidenceTherapeutic Level IV.Supplementary InformationThe online version contains supplementary material available at 10.1007/s43465-021-00366-w.     

经跗骨窦入路微创锁定钢板治疗跟骨关节内骨折疗效对比研究

目的:比较经跗骨窦入路使用微创锁定钢板与解剖型锁定钢板治疗跟骨关节内骨折的临床疗效。方法:回顾性分析2016年7月至2017年6月采用跗骨窦入路治疗的48例跟骨关节内骨折患者的临床资料,根据内固定方式不同分为微创锁定钢板组和解剖型锁定钢板组,每组24例。微创锁定钢板组,男14例,女10例;年龄27～46(38.70±5.58)岁;骨折Sanders分型,Ⅱ型18例,Ⅲ型6例。解剖型锁定钢板组,男17例,女7例;年龄26～46(37.10±6.44)岁;骨折Sanders分型,Ⅱ型16例,Ⅲ型8例。观察并比较两组患者手术时间,视觉模拟评分(visual analague scale,VAS),术后并发症情况,比较术后1周及末次随访时B?hler角、Gissane角、跟骨宽度和高度变化情况,采用Maryland足部功能评分进行功能评价。结果:所有患者获得随访,时间12～18(14.10±1.94)个月。48例患者获得骨性愈合,愈合时间8～16(10.60±2.25)周。微创锁定钢板组手术时间、VAS评分、并发症分别为(69.50±7.51) min、(2.80±1.07)分、2例,解剖型锁定钢板组分别为(77.50±7.15) min、(3.80±1.09)分、8例,两组比较差异有统计学意义(P0.05)。两组术后1周及末次随访时B?hler角、Gissane角、跟骨宽度、高度比较差异无统计学意义(P0.05)。两组Maryland足部功能评分比较差异无统计学意义(P0.05)。结论:对于SandersⅡ、Ⅲ型跟骨关节内骨折,经跗骨窦入路使用微创锁定钢板治疗可以达到与解剖型锁定钢板相似的牢靠固定及功能恢复,其操作更简便,手术时间更短,术后早期疼痛更轻,术后并发症更少。     

Aortic homograft implantation after Ozaki procedure: Case report

Introduction and importanceThe infective endocarditis incidence data for patients undergoing aortic valve neocuspidization with glutaraldehyde-treated autologous pericardium (Ozaki procedure) are rare, and the optimal surgical treatment strategy remains unclear.Case presentationThis is the first case report of surgical treatment of infective endocarditis of aortic valve with cryopreserved homograft in an athlete with previously performed Ozaki procedure.Clinical discussionThe choice of homograft was dictated by the young age of the patient; professional activity as an athlete; refusal of anticoagulants and the need for wide excision of compromised tissues to mitigate potential risk of spread of infection as well as its recurrence.ConclusionThe use of the aortic homograft allowed us to radically remove the infected tissues and achieve hemodynamic characteristics similar to the native valve. This is probably the first case report of use of homograft to treat aortic valve endocarditis following Ozaki procedure.     

急性重症胆管炎的救治体会

Effect of lesions of the ascending 5-hydroxytryptaminergic pathways on timing behaviour investigated with the fixed-interval peak procedure

Twelve rats received injections of 5,7-dihydroxytryptamine into the dorsal and median raphe nuclei; 12 rats received sham lesions. The rats were then trained for 60 sessions under a discrete-trials fixed-interval schedule (peak procedure). In half the trials, a reinforcer became available 40 s after trial onset, and the trial was terminated upon reinforcer delivery; the remaining trials were 120 s in duration, and reinforcement did not occur in these trials. Performance during the 120-s trials was characterized by increasing response rate during the first 40 s of the trial, declining response rate between 40 s and 80 s, and a secondary increase in response rate during the final 40 s of the trial. The lesioned group showed a broader spread of the response rate function than the control group (time between attainment of 70% of the peak response rate and subsequent decline of response rate below this level); however, the peak response rate and the time from trial onset until attainment of the peak response rate did not differ significantly between the groups; the spread/peak-time ratio was significantly greater in the lesioned group than in the control group. The levels of 5-hydroxytryptamine (5HT) and 5-hydroxyindoleacetic acid in the parietal cortex, hippocampus, amygdala, nucleus accumbens and hypothalamus were markedly reduced in the lesioned group, but the levels of noradrenaline and dopamine were not significantly affected by the lesion. The results confirm the involvement of 5HTergic function in timing behaviour.     

Pulmonary Failure After Norwood Procedure: Indication for Extracorporeal Membrane Oxygenation? A Case Report

Today some authors consider univentricular repair a contraindication for postoperative cardiac extracorporeal membrane oxygenation (ECMO). The question is whether or not ECMO is indicated as pulmonary support in case of an overwhelming pulmonary infection during the postoperative course after a Norwood procedure. During the prolonged weaning period after a Norwood procedure using a 4 mm aortopulmonary shunt, proven respiratory syncytial virus (RSV) bronchiolitis occurred at the time of expected weaning from artificial ventilation. Venovenous ECMO was able to improve oxygenation, but when pulmonary opacification failed to resolve, ECMO was terminated after 12 days.     

Acute clinical deterioration in a patient with end-stage dilated cardiomyopathy and left ventricular thrombus formation

The case of a 17-year-old male patient with severe end-stage dilated cardiomyopathy and a large thrombus formation within the cavum of the left ventricle is reported. After an acute thrombectomia combined with a partial left ventriculectomy (Batista procedure), the patient was successfully treated with an appropriate left ventricular assist device (LVAD) system using a centrifugal nonocclusive pump (Biomedicus, Medtronic, Anaheim, CA, U.S.A.). Mechanical support was removed on Day 9, and the patient was discharged from the hospital on Day 19. The effectiveness of emergency mechanical support in patients with very unfavorable prognoses is discussed.
