Role of Balloon Guide Catheter in Modern Endovascular Thrombectomy

Chueh, Ju-Yu,Kang, Dong-Hun,Kim, Byung Moon,Gounis, Matthew J. The Korean Neurosurgical Society 2020 Journal of Korean neurosurgical society Vol.63 No.1

Proximal flow control achieved with a balloon guide catheter (BGC) during endovascular treatment of acute ischemic stroke is reviewed in this article. In clinical practice, BGCs offer a multi-faceted approach for clot retrieval by creating proximal flow arrest, reducing embolic burden, and shortening procedure time. Evaluation of frontline thrombectomy procedures with BGCs revealed advantages of combined use over the conventional guide catheter (CGC), notably in the significant reduction of distal emboli to both the affected and previously unaffected territories. Recently, new measures of early and complete reperfusion at first thrombectomy pass have been identified as independent predictors of improved outcomes, which were consistently demonstrated with use of BGC as a safe and effective option to minimize number of passes during intervention. Prior randomized controlled trials reported the positive correlation between BGC-treated patients and a lower risk of mortality as well as shortened procedure time. While BGC use is more common in stent retriever-mediated mechanical thrombectomy, preliminary data has shown the potential benefit of device application during contact aspiration thrombectomy to achieve successful recanalization. However, the question of which major endovascular strategy reigns superior as a frontline remains to be answered. Along with clinical case assessments, BGC performance during in-vitro simulation was analyzed to further understand mechanisms for optimization of thrombectomy technique.

여성주의 비평가들의 엘리엇(T. S. Eliot) 연구

One of the most striking aspects of modem literature can be said to be a rising feminism, and feminists have contributed a great deal to our understanding of twentieth century woman writers, but they limit their understanding of both men and women writers by insisting on interminable sexual warfare as an explanation of literary modernism. Especially Sandra M. Gilbert and Susan Gubar among them seem dedicated to perpetuating wars between men and women by criticizing a massive critic T. S. Eliot. In this respect, this thesis aims to show the right way to approach his criticism by studying their methodology to maintain the polarity in his critical writings. Gilbert and Gubar contend that literary history is an exercise designed to retrieve male heroes and that tradition involves an attempt to define and protect the territory of male writers. They also, by using binary logic, devaluate Eliot's critical views on tradition and unified sensibility. But their strategy makes it impossible for them to see the complexity and subtlety of his thoughts. While undermining binary logic, he recovers harmony. He argues in his early philosophical writings that all oppositions and binary sets are unstable, and that fruitfulness is only possible through a combination of masculine and feminine values. Meanwhile Gilbert and Gubar, by polarizing men and women, eliminate all of the complexities in Eliot's literary criticism and completely miss the point of his concept on complementarity, but even though in fact he clearly suggests that unity can be imagined by insisting on difference.

This study aims to analyze T. S. Eliot's poetry and plays with a view to bringing out the modem mystery elements which function in them both as a dramatic device and as a theme with religious connotations. While many critics including Frank Wilson and David Jones have written on the plays of T. S. Eliot, only some have discussed these elements, but their analyses are not enough. Therefore, this study attempts to show how far Eliot uses the mystery elements to entertain the audience and at the same time to present his religious themes with an eye on the secular and rationalistic trend of the age. By employing the mystery elements Eliot had taken a significant step towards reviving religious mind in secular theater. In conclusion, Eliot uses the mystery elements to his own purposes. He introduces mystery aspects into some poems of his, where these thriller elements play a basic role in developing his interest in detective stories. In Murder in the Cathedral and the subsequent plays the mystery elements impart greater dramatic interest to the religious themes. The insertion of the crime mystery into his works plays a key role in showing his interest in the popular culture. Murder in the Cathedral is a unique play not only because it is an example of a modem mystery play but also because it illustrates the combination of the religious and the secular, the high and the low, and more specifically the use of mystery elements for the exposition of a serious theme. The Family Reunion nearly completes the pattern of a story of crime and punishment ironically reminding of Dickens and Dostoevsky again which is finally transformed into the drama of sin and expiation. The mysterious guest and his companions in The Cocktail Party who remind of several mystery detectives are finally recognized as symbolic figures who help to unite the estranged couple and dispatch the protagonists on different paths of salvation. In The Confidential Clerk there is some real fun in the thriller type of pursuit and analysis of evidence to explore the identities of an unknown father, whose money was swindled away, and a "true" father who had some connections with the church. In The Elder Statesman Eliot shows consistency in the employment of mystery elements such as hidden "crimes", horror and fear of detection, the evidence, and confession of guilt.

Anti-GQ1b 항체 양성을 보인 Mycoplasma pneumoniae 감염에 의한 Miller-Fisher 증후군 1례

저자들은 전형적인 외안근 마비와 운동실조, 심부건반사 소실 증상을 보이고 항 GQ1b 항체가 양성으로 측정되면서 선행 감염원으로 Mycoplasma pneumoniae 항체가가 양성으로 증명된 8세 남아의 Miller-Fisher 증후군 1례를 경험하였기에 보고하는 바이다. Miller Fisher syndrome, first reported by Miller Fisher in 1956, is characterized by a triad of external ophthalmoplegia, areflexia, and ataxia. Many features shared with Guillain-Barré syndrome; CSF usually shows elevated proteins and the syndrome is often is preceded by an infectious disorder. It is believed that the level of anti-GQ1b IgG antibody is elevated during an acute phase, increases and decreases rapidly during clinical recovery, that the level of anti-GQ1b IgG can be used as a diagnostic tool for Miller Fisher syndrome during an acute phase. We report an 8 year-old boy who showed typical clinical manifestations of Miller Fisher syndrome, with respiratory tract illness, associated with the seroconversion of Mycoplasma pneumoniae titers during the development of neurological symptom, with positive anti-GQ1b IgG.

앤 섹스턴(Anne Sexton)의 패러디(parady)에 나타난 남성과 여성의 역할

최영승 신한영미어문학회 1997 새한영어영문학 Vol.36 No.-

Anne Sexton, in her Transformations a parody of Grimm's fairy tales, concerns with the roles of men and women, expressing the actual aspect of their patriarchal society which women are brought pressure upon by men. Her feministic attitude against patriarchy arises from her strong antipathy to the traditional views of women. She loses her won identity in her role as housewife and her double egos as mother and poet are divided in her most poems. In this respect this study aims to enlarge the scope of understanding Sexton's parody poems by making clarify the meaning of the roles of characters in Transformations. 'The Maiden without Hands' expresses love and lust of a man in patriarchal society. And 'Twelve Dancing Princesses, also represents the typical image of the dictatorial father. Sexton's interest in incest embodies 'Briar Rose' in which father plays a role of lover to his daughter. While Sexton describes the pretty princess as a stupid rabbit in 'Show White and the Seven Dwarfs' and she brings a cannibal witch into 'Hansel and Gretel'. She also compares an evil woman with a wounded mother in 'Rumpelstiltskin'. In 'The Little Peasant' Sexton Draws an independent woman based on the theme of adultery. Therefore Anne Sexton tries to strengthen the creative power of women for recovery of dignity through the role changes in her parody Transformations. Her gynocentric discourse can get the power through the relationship between men and women. In her poetry men exist in the center of dignity and women do not be excluded from its center and marginalized.
