Microsurgery has always been the main treatment for large vestibular schwannomas. With the progress of microsurgical technique and neuroimaging, the application of the intraoperative physiological monitoring technology, as well as the popularization of the concept of minimally invasive neurosurgery, the current development trend of surgery for vestibular schwannomas is to realize both the maximal tumoral resection and the maximal preservation of facial nerve function, which puts more emphasis on the improvement of quality of life. It is still a challenge for neurosurgeons to resect the tumor to the maximum extent and preserve the nerve function as well. In view of this background, the strategy of " near-total resection” and " subtotal resection” combined with stereotactic radiotherapy has been more and more accepted in the past years. However, as a neurosurgeon, the ultimate goal should be " gross-total resection of tumor” and preservation of the nerve function as well. For those tumors severely adherent to neurovascular structure, " near total resection” might be a rational choice. Meanwhile, long-term follow-up should be conducted to clarify the biological behavior of tumor residues, as well as the necessity and long-term effect of stereotactic radiotherapy.
Endovascular treatment for acute ischemic stroke has become the main therapy for large vessel occlusion. In addition to stent thrombectomy, in recent years, the application of aspiration thrombectomy is becoming more and more common. The physical principles of aspiration and stent thrombectomy extraction are different. The thrombus is captured by the negative pressure generated by suction through the contact between the reperfusion catheter and the thrombus, thus achieving cerebrovascular recanalization. Currently, more and more researches support the application of aspiration thrombectomy. What are the advantages and disadvantages of the aspiration thrombectomy compared with the stent thrombectomy and how to apply the aspiration technology reasonably are the hot issues concerned by everyone. This paper reviews the application and research progress of aspirating thrombectomy in order to provide reference for clinical treatment decisions.
Objective To collect evidence of treatment for the patients with ocular myasthenia gravis. Methods We searched The Cochrane Library (Issue 1, 2010), PubMed (1966 to April, 2010), CNKI (1979 to April, 2010) and VIP (1989 to April 2010) to identify systematic reviews, randomized controlled trials, controlled clinical trials and prospective avaicohort studies about efficacy and safety of treatment for ocular myasthenia gravis. Results We identified 2 guidelines, 5 systematic reviews and 4 observational studies on inhibitor of acetylcholinesterase, immunosuppressive agents, intravenous immunoglobulin, corticosteroids, and thymectomy for ocular myasthenia gravis. The first choice for ocular myasthenia gravis was inhibitor of acetylcholinesterase. When the symptom could not be remitted, the corticosteroids should be considered. Immunosuppressive agents might be added if the effect of corticosteroids was not good. Plasma exchange was not recommended. Thymectomy should be performed if the patients suffered from thymoma. Conclusion The best clinical evidence can be available by the evidence-based method.
ObjectiveTo explore the risk factors of stroke-associated pneumonia (SAP) in the patients with acute ischemic stroke, in order to provide effective guidance for clinical prevention and treatment.MethodsFrom November 2016 to November 2019, 330 patients with acute ischemic stroke admitted to the Department of Neurology of West China Hospital of Sichuan University and the Department of Neurology of the Sixth People’s Hospital of Chengdu were selected as the research object. The clinical data of the patients were analyzed retrospectively. According to whether SAP occurred, they were divided into infected group and non-infected group. Multivariate logistic regression model was used to analyze the risk factors of SAP.ResultsA total of 71 cases of SAP occurred in patients with acute ischemic stroke, accounting for 21.52%. Logistic regression analysis showed that age≥70 years old [odds ratio (OR)=3.677, 95% confidence interval (CI) (1.452, 9.311), P=0.006], chronic lung disease [OR=4.985, 95%CI (1.558, 15.952), P=0.007], disturbance of consciousness [OR=7.147, 95%CI (1.617, 31.587), P=0.009], bulbar palsy [OR=5.909, 95%CI (2.668, 13.089), P<0.001], the use of nasal feeding tube [OR=7.427, 95%CI (1.681, 32.812), P=0.008] were independent risk factors for SAP in patients with acute ischemic stroke.ConclusionsAge≥70 years old, chronic lung disease, disturbance of consciousness, bulbar paralysis and use of nasal feeding tube are independent risk factors for SAP. It is necessary to strengthen the management of these risk factors in order to identify high-risk patients with SAP early, and develop intervention strategies for risk factors, so as to improve the prognosis.
Stroke with hereditary cerebral small vessel diseases is a rare disease. Its clinical manifestations include early-onset ischemic lacunar or hemorrhagic stroke with high disability. Its typical imaging markers include lacunes, white matter hyperintensities, microbleeds, intracerebral hemorrhages located in deep or lobe of brain, crotical microinfarcts, and enlarged perivascular spaces. As the clinical and neuroimaging signs and symptoms of hereditary cerebral small vessel diseases often overlap with sporadic cerebral small vessel diseases, it is hard to diagnose. This article summarizes the clinical features, importance of obtaining valuable family history, genetic diagnosis, and management of stroke with hereditary cerebral small vessel disease to improve its accuracy diagnosis.
Substantial progresses have been made in cerebral vascular diseases in 2017. By retrospectively analyzing the clinical researches which Chinese experts participated in or were in charge of, this article briefly summarizes the update of stroke epidemiology, explorations of stroke-related risk factors, early management of acute stroke, secondary prevention and prognosis of stroke. These researches include the problems about the dose of thrombolysis medicine, new type of antiplatelet and anticoagulant drugs, prognosis of intracranial hemorrhage and signs of intracranial hematoma enlargement, which have close connection with clinical work and are valuable in practice.
High mobility group box 1 (HMGB1) is widely expressed in mammalian tissues and cells which is involved in various pathophysiological processes such as inflammation, autophagy, and apoptosis, and plays an important role in maintaining cell survival and normal function. HMGB1 plays an important part in the development of stroke, which can affect the prognosis by inducing neuroinflammation and autophagy. HMGB1 may have a bidirectional effect in acute and chronic phases. Exploring the specific role and mechanism of HMGB1 in each stage of stroke may make it a new target for prevention and treatment in the future.
Objective To determine whether Xingnaojing injection can improve functional outcome without causing harm in patients with intracerebral hemorrhage. Methods We searched the electronic bibl iographic databases: Cochrane Central Register of Controlled Trials(CENTRAL, Issue 3, 2007), MEDLINE (1996 to November 2007),EMBASE (1984 to November 2007) and China Biological Medicine Database (1978 to November 2007). We also did handsearching to identify other publ ished and unpubl ished data. Data were extracted and evaluated by two reviewers independently with a designed extraction form. The Cochrane Collaboration’s RevMan 4.2.10 was used for data analysis. Results Thirteen randomized trials involving 1 035 patients were included. The number of people who had died or were dependent at the end of long-term follow-up (at least 3 months) were reported in three trials. Eleven trials measured neurological deficit at the end of treatment. No severe adverse events were reported. The results of meta-analyses indicated that Xingnaojing injection might decrease the number of death or dependency compared to the control group, but the difference was not statistically significant (Peto-OR 0.57, 95％CI 0.32 to 1.01); and Xingnaojing injection were associated with a significant improvement in neurological deficit (Peto-OR 3.70, 95%CI 2.67 to 5.13). Conclusion The evidence currently available showed that Xingnaojing injection may decrease the risk of death or dependency, and can also reduce neurological deficit in patients with intracerebral hemorrhage. However, more high-qual ity trials are needed.
Lung transplantation has been proved to be an effective treatment after more than forty years of fast development, while more than 4000 cases of lung transplantation performed globally each year. Recently, lung transplantation in China has been advanced rapidly, and the number of transplants has increased year by year. Respiratory and Critical Care Medicine team has been recognized to play a crucial role in lung transplantation. It has an irreplaceable role and status in promoting lung transplantation, improving the preoperative evaluation of lung transplantation and the maintenance of donors, and carrying out perioperative management, as well as long-term follow-up. Lung transplantation is a systematic project, requiring the perfect cooperation and collaboration of team members and contributing to recipients’ recovery.
Objective To investigate the long-term prognosis of cerebral venous sinus thrombosis (CVST) and to identify the early predictors of poor outcome. Methods We performed a prospective register study on the prognosis of CVST patients. All patients were followed up continuously. The primary endpoint was death or dependence as assessed by the modified Rankin Scale (mRS) score gt;2 at month 6. A multivariable logistic regression model was applied to identify the predictors of outcome. Results A total of 52 CVST patients were included. The rates of recurrence and death at month 6 were 13.5% and 7.7%, respectively, and 29.9% of the patients were dead or dependent at month 6. The multivariable logistic regression analysis revealed that the predictors of death or dependence at month 6 were intracranial parenchymal lesion (OR=14.62, 95%CI 2.36 to 90.36) and delayed diagnosis (OR=13.14, 95%CI 1.90 to 90.84). Conclusion In China, CVST is still a disease that may lead to death or dependence. Its long-term prognosis is relatively poor compared to that reported in western patients. This difference may due to the delayed diagnosis of CVST in China.
